DuduPhudu	48106d3c00	fix(ingestion): index NestJS decorator routes so api_impact and route_map stop reporting live endpoints as non-existent (#3017)	2026-08-27 08:35:36 +01:00
DuduPhudu	2c0fb7753c	fix(group): stop reporting what could not be measured as a measurement of zero (#3012) ... * fix: surface unreadable group indexes and escape raw NUL bytes in source Two independent diagnostics failures, both of which turn a real error into a confident, benign-looking answer. **Unreadable member repos (#3011).** `syncGroup` wrapped `initLbug` plus all contract extraction for each member in a bare `catch {}` that pushed the repo onto `missingRepos` and discarded the error. A LadybugDB storage-version mismatch therefore surfaced as "repo not found", `group sync` printed `0 contracts, 0 cross-links` and exited 0, and the existing contracts.json was overwritten with an empty registry. The two states need different answers from the operator — a missing repo must be indexed, an unreadable one is usually version skew or a lock — so they are now separate: - the caught error is logged with the repo, group path and lbug path - `unreadableRepos` is tracked alongside `missingRepos` on `SyncResult`, persisted (optionally, so older registries still parse) on `ContractRegistry`, and threaded through `GroupService` sync/status - `group sync` reports both before the cascade counts, since an unread repo is the likely explanation for a small or empty count - `group status` reports unreadable repos separately; calling them "missing" actively misdescribed them - when EVERY configured repo fails to open, the write is skipped: an extraction that read nothing is not evidence the group has no contracts, and replacing a good registry with an empty one loses data while reporting success **Raw NUL bytes (#3010).** `sync.ts` and `free-call-fallback.ts` each used a NUL as a join delimiter, written as a literal 0x00 instead of `\0`. Identical at runtime, but it makes the file test as binary: `file(1)` reports `data`, ugrep returns empty with exit 1 — indistinguishable from "no match", with no message — and BSD grep replaces matching lines with "Binary file ... matches". A search that should hit comes back as a confident "not present". Both now use the escape, and a unit test fails on any raw control byte in src/ so it cannot silently return. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(hygiene): guard every tracked source file against a raw NUL, not just src/ The guard added with the NUL escapes only scanned gitnexus/src for .ts/.tsx. Neither prior recurrence of this defect in this repo was in that scope: b620773b1 was gitnexus/bench/cpp-qualified-ns/measure.mjs and 38d737bb5 was a fixture under gitnexus/test. A guard that cannot see where the bug has actually landed twice is not a guard. Drive the file list from `git ls-files` at the repository root over .ts/.tsx/.js/.jsx/.mjs/.cjs/.mts/.cts — 2483 files instead of 828 — and split the byte class, which is the part that matters: - 0x00 is a hard failure repo-wide. It is the byte git's binary heuristic keys on, so it is the one that costs a file its diff (and, on the base side of a PR, its inline-comment anchors and its three-way merge). - The wider C0 class stays scoped to gitnexus/src. A repo-wide scan finds exactly one hit, test/unit/logger.test.ts:146, and that 0x1b is a legitimate ANSI-escape fixture that is the subject of the test. Widening this half would go red on day one. Read Buffers and scan bytes instead of decoding each file to latin1, through a bounded read pool: 1.5 s for 2483 files, against 8-21 s previously for 828. Add a negative fixture — a planted 0x00 and 0x1b run through the same scanning helper — so a future refactor of the collector cannot leave a permanently green guard, plus an assertion that the collected set still reaches bench/, test/ and .mjs, which goes red if the scope is ever narrowed back.

Nothing in the impact walk could notice: the only incompleteness channel on a GroupImpactResult is truncationFields(), which is driven by fan-out state (truncatedRepos / localPartial / fanoutTimedOut), and a repo missing from the bridge sets none of them. So `group impact` on a symbol whose one downstream consumer lives in an unreadable repo returned `{ cross: [], truncated: false }` — "complete: nothing in another repo depends on this". That is a wrong answer, not an empty one, for a tool an agent uses to license a delete or a rename. BridgeMeta now records unreadableRepos alongside missingRepos, writeBridge persists it when non-empty, and runGroupImpact folds a non-empty unreadableRepos ∪ missingRepos into truncated / riskEpistemic: 'lower-bound', naming the repos in truncatedRepos. The reason is a new 'incomplete-sync' rather than the existing 'partial' because the remedy differs: 'timeout' and 'partial' are runtime limits the same query can clear on a retry, while this one clears only when `gitnexus group sync` succeeds. Runtime limits still take precedence when both apply, since those are what the caller can act on immediately. The risk VALUE is never clamped down — mergeRisk is monotone in the traversed crossing count, so an incomplete bridge can only under-report. Marking the floor is what makes that legible. Both shape changes are additive and optional, so a bridge written before this still reads.

Every item below is a place where the code still answered a question it could not answer. 1. The CLI announced a write it did not perform. `group sync` printed "Wrote contracts.json (0 contracts, 0 cross-links)" unconditionally, including on the path that deliberately left the file alone. SyncResult now carries registryOutcome ('written' | 'preserved' | 'not-attempted'), the CLI prints from it, and group_sync returns it so an agent that calls group_sync then group_contracts can tell why the counts disagree. 2. Refusing to write anything on total failure threw away the diagnostic describing the run that just happened. `group status` reads contracts.json from disk, so the operator who saw the sync fail and ran status to find out why read the PREVIOUS sync's file: no unreadable list, an old lastSync, a healthy-looking group — or worse, the previous run's unreadable list presented as this one's. The skip is now targeted: contracts, crossLinks, repoSnapshots and generatedAt carry forward verbatim, only missingRepos and unreadableRepos are refreshed. generatedAt stays put because it dates the contracts, which are still the previous run's. With no prior file, or an unparseable one, nothing is written at all. 3. Per-repo extraction is now all-or-nothing. Extractors run in sequence and any one can throw; appending each one's results straight to autoContracts meant a repo whose HTTP extractor succeeded and whose gRPC extractor then failed contributed a partial set to the registry, while the same run told the operator that repo's "contracts are omitted from this sync". 4. readRegistry gains an opt-in strict mode, and syncGroup uses it. The lenient `catch { return []; }` converted "I could not read the registry" into "no repo is registered": every configured repo then resolved to MISSING, the total-failure guard stayed off (it needs a load error), and a good contracts.json was replaced by an empty one at exit 0. That is an unreadable condition reported as missing, one frame above the code this branch fixes. The default stays lenient for the other nine callers; ENOENT stays lenient in both modes. 5. Absence of unreadableRepos keeps meaning "not recorded". The loader spreads the key in only when present instead of defaulting to [], and getStatus passes undefined through, so a legacy registry no longer reads as "the last sync found none unreadable". getStatus also gates both list fields on Array.isArray: it reads through readContractRegistry, which is a bare JSON.parse cast, so a corrupt string in either slot used to reach cli/group.ts and die in .join(', ') — the command whose job is explaining an unreadable thing, crashing on one. 6. Smaller, same theme: the per-repo warning passes the Error itself rather than err.message, so pino keeps the stack; the total-failure warning no longer fires on a dry run, where it described a file the call was never going to touch and which need not exist; the status table's MISSING legend stops re-conflating the two states; the sync warning drops its GITNEXUS_LOG_LEVEL=warn hint, which would only have suppressed output (pino emits warn at the default info level, so the reason was already printed); and the group_sync tool description and its idempotency comment now describe what the tool actually does. Testing. The original four cases could not see the change they were named after. Mutation testing showed two survivors: dropping the === configuredRepoCount conjunct, which turns "every repo failed" into "any repo failed" and would silently freeze contracts.json for a group where one of five repos is skewed; and deleting both logger.warn calls, the stated purpose of the change. Both survived because every case configured exactly one repo and nothing read the log. There is now a two-repo case running the real per-repo loop, an all-missing case, a _captureLogger assertion on the level 40 record, partial-extraction cases, and strict-read cases. All five mutants are killed, each by exactly one test.

It went unnoticed because `tsconfig.json` is src-only; `tsconfig.test.json` reports it. The older of the two fixtures carried the gap in from the original commit. 2. `runGroupImpact` named its truncation reason in a variable computed before the truncated check, so on a fully complete result the variable read 'incomplete-sync'. `truncationFields` discards the reason when `truncated` is false, so nothing surfaced — but a value that is wrong whenever it is unused is a trap for the next reader. Computed inline at the one call site that can consult it, which is also how the neighbouring call sites are written. 3. `Array.isArray` alone let a corrupt registry through. `['app/backend']` and `[{repo:'x'}]` are both arrays, and only the second reaches `cli/group.ts`'s `.join(', ')` — as `[object Object]`, a measurement the operator can read but cannot act on. Both readers now go through one `recordedRepoList` helper that requires an array of strings; anything else is "not recorded", the same as absent. Two more rows in the corrupt-value table cover it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014g48u4WcRZy543Wqp5NhpV * fix(group): keep readRegistry's signature, and stop describing unreadableRepos as index-only Two items from the check bot's blocking pass. 1. `readRegistry` gained an optional `opts` parameter last commit. That is source-compatible — every zero-argument call still compiles and behaves identically — but the contract check treats any parameter-list change on a symbol with outside callers as a break, and it is right that the safest version of this change touches that signature not at all. The strict read is now its own export, `readRegistryStrict()`, over a shared private body. `readRegistry()` is byte-identical to what it was; `syncGroup` is the only caller of the strict one, and the mode is legible at the call site instead of hiding in an options bag. 2. `unreadableRepos` is described everywhere as "the index could not be opened". That was accurate before this branch and is not now: making per-repo extraction all-or-nothing means a repo also lands there when an extractor throws partway with the index open fine. The two belong in one bucket because the consequence is one thing — none of that repo's contracts are in this sync — but the docs have to say so, or an operator reads `unreadableRepos` as a storage diagnosis and goes looking at LadybugDB for an extractor bug. Corrected on `ContractRegistry`, `BridgeMeta`, `SyncResult`, the `group_sync` tool description, and the `group sync` console output, which now says "Could not extract contracts from" rather than "Could not read the index for".

The status line named only the first — "registry predates this field" — so a corrupt value read as a merely old registry. That is the same shape of wrong answer this command exists to stop giving: a condition we could not read, presented as a benign one we understand. The line now names both, and asks for a sync either way, which is the fix in both cases. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014g48u4WcRZy543Wqp5NhpV * fix(group): close the three fail-open paths left on the safety boundaries Follow-ups from the re-review of 31c2b6e81. All three of its blocking findings reproduce; each is a place where unknown state still resolved to a confident benign answer, which is the one thing this branch exists to stop. 1. Strict registry reading accepted malformed rows. `[{}]` is a JSON array, so it passed the shape check: every configured repo then failed to resolve into `missingRepos`, none produced a load ERROR, the total-failure guard stayed off, and a good contracts.json was replaced with an empty one at exit 0 — the same fail-open the strict mode was added to close, one level down from the file to the rows inside it. Strict mode now requires `name`, `path` and `storagePath` on every row and rejects the WHOLE registry if any row fails. Rejecting rather than filtering is the point: dropping bad rows would report the repos they name as unregistered, which is the same wrong answer again. `indexedAt` / `lastCommit` are deliberately not required — callers already default them, so demanding them would trade a fail-open for a fail-shut on a legitimate legacy registry. 2. A failed bridge publication could make impact look complete. `writeBridge` swaps `bridge.lbug` and writes `meta.json` as two operations, and this branch made that meta load-bearing: `runGroupImpact` derives its truncation fields from it. A sync interrupted between the two steps therefore left a NEW bridge beside the PREVIOUS sync's metadata, and an impact query read that as "complete". Fixed from both ends. The write path removes the old meta before the swap, so the window leaves metadata ABSENT rather than stale. The read path treats absent-or-unparseable meta (`version: 0`) as unknown provenance and reports a floor, which also covers the caught `writeBridge` failure in `syncGroup`. Over-reporting truncation on a bridge that is actually fine is the safe direction, and the next successful sync clears it. 3. `preserved` was returned when there was nothing to preserve. On a group's first all-unreadable sync the outcome was set before the prior registry was read, so the CLI told an operator "the contracts from the previous sync are preserved" about a file that had never existed. Split out as `no-prior-registry`, with its own console message. Also widened the NUL guard to the source languages it claimed to cover. The commit that added it said "every tracked source file" while the collector stopped at the JS/TS family, so a raw NUL in tracked Python, Java, Go, Rust, C/C++, Ruby, PHP, Kotlin, Swift, C# or shell would still have turned those files binary unnoticed. Measured before widening: 2315 non-JS tracked source files, zero hits, so this was an unforced gap rather than a tradeoff. A planted `.py` fixture and a collector-coverage assertion keep it honest. Every fix is mutation-verified: reverting each one individually turns its own tests red (3, 2, 2, 1 and 1 failures respectively), and all pass together. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014g48u4WcRZy543Wqp5NhpV * fix(group): record the empty unreadable measurement instead of dropping it Both writers omitted `unreadableRepos` when it was empty, which made the tri-state this branch introduced unreachable in its most common case. `ContractRegistry.unreadableRepos` is optional on the TYPE so a registry written before the field existed still parses, and absence there means "not recorded". But a sync that read every repo successfully HAS measured it, and `[]` is that measurement. Dropping it collapsed "measured, none" into "never recorded", so after every clean sync `gitnexus group status` printed Last sync unreadable repos: not recorded (the registry predates this field, or its value could not be read) Re-run `gitnexus group sync` to record it. about the sync that had just succeeded. The distinction is only worth having if the writer commits to it, so both `contracts.json` and the bridge's `meta.json` now record the field whenever the sync supplied it, `[]` included. The check bot found this on the bridge writer and attributed the consequence to `group status`. The consequence is real but it is not the bridge's: `getStatus` reads `contracts.json` and never touches `BridgeMeta`, whose only consumer is `runGroupImpact` — where absent and empty are already equivalent. So the user-visible half was in the registry writer, one file over from where it was reported, and both are fixed. Also fills in `DetectConfig.includes` (and `workspace_deps`) across the group test fixtures that predate those fields. These are pre-existing on main and are a no-op at runtime — `undefined` and `false` are both falsy at the gate — but they are the same defect the bot flagged as an error in the new fixtures, and `tsconfig.test.json` reported eleven of them. That file is not in CI, which is why they survived; the group tree is now clean of them. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014g48u4WcRZy543Wqp5NhpV * test(group): stop two bridge-metadata tests claiming coverage they do not have Both were named for the swap window and neither injects a swap failure. "drops the previous meta.json before swapping the database file" runs two successful writeBridge calls. Its assertions hold with the removal in either position, because writeBridge overwrites meta.json at the end regardless — so it cannot pin the ordering it is named for. Renamed to what it does cover, the successful-rebuild replacement, with the limit stated in the body rather than left for the next reader to discover. "leaves NO meta.json when the swap fails partway" removes the file by hand after a successful write, so it exercises readBridgeMeta's missing-file contract, not writeBridge. That contract is worth pinning on its own — version 0 is the signal runGroupImpact fails closed on — so the test stays, under a name that says so. The ordering itself is pinned in bridge-meta-swap-window.test.ts, which mocks retryRename to throw on the bridge.lbug swap and asserts the previous sync's metadata cannot survive it. Both renamed tests now point there, so the coverage is findable from the place someone would look for it. No production code changes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014g48u4WcRZy543Wqp5NhpV * fix(group): pair bridge metadata to its database instead of deleting it The previous commit closed the swap/metadata window by removing meta.json before the database swap, so the window would fail to "absent" rather than "stale". That was the wrong trade, and it destroyed recoverable state. The old database's move to `.bak` sits inside a catch that swallows failures, not just "no existing db". When that rename fails — a held read-only handle does this on Windows, and a long-lived MCP server holds one — the failure is swallowed, the following `tmp -> bridge.lbug` throws, and writeBridge exits with the OLD database still in place and perfectly valid. Its metadata was already deleted. Cross-repo impact then answers "we cannot say" for that group until some future sync succeeds, and if the cause is a held handle or permissions there is no such sync. A working feature, destroyed permanently to close a narrow window. Deleting also only chose which way the window failed; it never closed it. So destroy nothing, and make the pair self-describing instead: writeBridge stamps the database's size and mtime into the metadata it writes, and `bridgeMetaMatchesFile` lets a reader ask whether the two still belong together. `runGroupImpact` treats a mismatch the same as absent metadata — provenance unknown, report a floor. A metadata file left over from an earlier sync cannot match a freshly renamed database, and a sync that fails before the swap leaves a matching pair untouched. Metadata written before the stamp existed is unverifiable rather than stale, and is accepted: failing those closed would mark every pre-existing bridge incomplete, trading a narrow window for a repo-wide regression. The swap-window test now distinguishes the two failure shapes, because they want different answers. When every rename fails the old database never moves, so the surviving metadata still matches it and impact keeps answering from it. When only the final rename fails the old database has already reached `.bak` and no database is in place, so the metadata correctly matches nothing — and `ensureBridgeReady` fails loudly on the absent file, which beats a silent floor. Mutation-verified: reinstating the delete, neutering the pairing check, and dropping the stamp each turn 2, 3 and 3 tests red respectively.

This branch removes it, but the base side still has it, so the file renders as "Binary files differ" in the pull request: no hunks, no inline comments, and no three-way merge — however clean the head side is. A head-side byte guard cannot detect that, by construction, since it only ever sees the working tree. Setting the `diff` attribute stops the heuristic from hiding the change. It does not mark the files binary, does not imply `text`, and does not change how blobs are stored, normalized, or checked out — the root `* text=auto eol=lf` still governs all of that. It affects diff generation and rendering only. Locally this turns the branch's own sync.ts diff from `Bin 17612 -> 25346 bytes` into 154 insertions and 16 deletions. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): answer "provenance unknown" for malformed bridge metadata `readBridgeMeta` guarded the read and the parse but not the SHAPE of what it parsed, then cast the result. `runGroupImpact` spread both repo lists straight into a Set, so a `meta.json` whose `missingRepos` held an object threw a TypeError out of the entire cross-repo query — and threw it from a point after `ensureBridgeReady` had taken the bridge lease and before the `try` whose `finally` releases it, so every such query also leaked a refcount the cached handle could never get back. A malformed file is a reason to answer "we cannot say", never a reason to crash the question. The shape gate now lives where the metadata is read, mirroring the one `service.ts` already applies to the registry's copies of these same two lists. Each list is judged independently: a garbage `unreadableRepos` no longer discards a `missingRepos` that was genuinely measured. A list that was present but unusable is dropped rather than normalized to `[]`, because an unreadable value is not a measurement of zero — the new reader-side `repoListsUnreadable` carries that distinction, and `runGroupImpact` folds it into the same provenance-unknown verdict it already reaches for `version: 0` and for metadata that does not pair with the database beside it. A root that is not an object is closed too. `JSON.parse` succeeds on `null`, `7` and `[]`; the first threw on `.version`, and the other two read `undefined` and sailed through the version gate as if the bridge had been vouched for. Both provenance values moved inside the protected region and are initialized fail-closed, so a future throw between the lease and the walk releases rather than wedges. `repoListsUnreadable` is reader-side only: the sole `writeBridgeMeta` call site builds a fresh literal, so nothing persists it and no schema version moves. Mutation-verified: reverting the shape gate alone turns 4 tests red — the three malformed-list scenarios plus the handle-release regression. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(storage): reject registry rows that cannot identify a repo The strict read's row gate gave `typeof v === 'string'`, and `typeof '' === 'string'`. A row whose `name` was blank therefore passed as resolvable, then matched nothing in `defaultResolveHandle` — putting every configured repo in `missingRepos` and presenting an unusable registry as a clean answer about an empty one. That is the same unreadable-as-missing fail-open the strict mode exists to close, one level further in. A blank `storagePath` is worse than useless: it joins to a relative `lbug` under the current directory, so the sync opens an index that is not the repo's. Both now have to be non-blank after trimming. `path` stays at the bare string check, on the same reasoning that already exempts `indexedAt`/`lastCommit`: require only what resolution depends on to IDENTIFY the repo. This gate rejects the whole registry and the registry is machine-wide, so a field tightened past what identification needs would let one blank value in one row break every group sync on the machine — including groups whose repos all resolve. A blank `path` still yields a working handle; `defaultResolveHandle` does read it, but only for the pool id and `repoPath`, neither of which decides whether the row names a repo. The error now says what is actually wrong instead of naming three fields that are all present. Mutation-verified in both directions: dropping the trim turns the three rejection tests red, and applying the wider fix that was considered and declined — tightening `path` too — turns exactly the counter-case red, so that test genuinely pins the narrow reading rather than passing either way. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): bound the per-repo contract staging append `autoContracts.push(...repoContracts)` passes every staged contract as a separate argument, and the engine caps how many arguments one call may take. That cap is a function of the host's available stack, so it is a different number on every machine — this one accepts a 125k-element spread and dies at 150k. The spread itself is not new; what it carries is. Before staging, this line appended a single extractor's output as it came back. Staging made it carry the whole repo's, which is enough for a large repo to raise `RangeError: Maximum call stack size exceeded` on the one line whose job is to commit work that just succeeded. The throw lands in the catch below, so the sync reports a repo whose extractors all ran cleanly as one whose index could not be read — a crash wearing the costume of a diagnostic. A bounded loop replaces it: the count a repo can stage is now bounded by memory rather than by how much stack the process happened to get. The guard is structural, not size-based, and deliberately so. A "make the fixture big enough to crash" test passes against unfixed code on any host with a larger stack, which is exactly the guarantee a regression gate cannot give up. It walks the AST and locates the region by role — the `const` staging buffer typed `StoredContract[]`, then the extractor `try` that is a direct statement of the block declaring it — so renaming either identifier keeps it pointed at the same code. `.apply()` is rejected alongside spread, being the same hazard in different syntax. Direct statements only, because `syncGroup` wraps this whole section in its own try/finally for the lease sweep, and that ancestor reads the buffer too. Matching any enclosing `try` pulls in the entire function body — including the two windowed-manifest spreads, which are bounded by the window size and are not what this fixes. Mutation-verified in both directions: restoring the spread turns the gate red naming that line alone; deleting a manifest-window spread, and separately adding a third one, both leave it green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): keep unreadable repos out of manifest contracts too Per-repo staging closed one door: a repo whose extractor threw contributes nothing through the direct path. Deferred manifest resolution was a second door, still open. It derives its known-repo set from the resolved-handle map, which kept an entry for a repo the same run had already declared unreadable — so the sync re-opened that index and resolved symbols against a database it had just told the operator it could not read. Deleting the handle in the catch stops the re-open, but it does not satisfy R2 on its own: `ManifestExtractor` resolves both endpoints of a link and emits a contract for each, and for an endpoint with no executor that contract is still emitted with a synthetic UID. The registry ended up naming a repo the same run reported unreadable. So the emitted output is filtered by ENDPOINT, not by link. Dropping the whole link would delete the healthy partner's contract as well — a repo losing its own output because a neighbour's index would not open, which is wider than the requirement and destroys good data to suppress bad. A cross-link is different: it asserts something about a pair, so if either end is unreadable there is nothing left to anchor it to, and a half-anchored link is exactly the confident-about-what-it-could-not-read answer the registry must not give. Deleting the handle also changed what the operator gets told, so the warning is split. An unreadable repo IS configured; letting it fall into the "references repos not in config.repos" branch states something false and sends the reader to edit group.yaml for a problem only re-indexing fixes. It now gets its own message naming what was actually omitted. Mutation-verified four ways: reverting the endpoint filter turns three scenarios red; the over-broad whole-link variant turns the healthy-partner scenario red and nothing else; removing the handle delete turns the no-re-open scenario red; and reverting the warning split turns the operator- message scenario red. Every assertion reads the written contracts.json rather than the in-memory result. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(group): keep readBridgeMeta's signature stable across the shape gate The shape gate landed by widening the return type to a reader-only `ReadBridgeMeta extends BridgeMeta`. That is source-compatible — a covariant return, one added optional field, every existing caller unaffected, typecheck and suite clean — but the contract check reads it as a changed signature with a caller left behind, and blocks the merge on it. This branch already hit the same wall on `readRegistry` and settled it the same way: leave the signature alone and make the difference legible some other way. So the flag moves onto `BridgeMeta` itself as an optional, documented, never-persisted field, and `readBridgeMeta` goes back to the exact signature its callers already compile against. That is the better shape here anyway. The reader-only subtype would have split the validation two ways: `openBridgeDbReadOnly` and `bridgeExists` both gate on `meta.version`, and the normalization that comes with the gate is what stops a `version: null` in a hand-edited meta.json from reading as `undefined` and sailing through `version > 0` as though the bridge had been vouched for. One type keeps all three callers behind the same guard. Nothing persists the flag: `writeBridgeMeta`'s only caller builds a fresh literal, so it cannot round-trip to disk. No behavior change — pure type restructuring. 927 tests pass, typecheck clean. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): stop treating a half-written bridge stamp as a verified match `bridgeMetaMatchesFile` joined its two `undefined` checks with `||`, so metadata carrying a size and no mtime — or the reverse — returned `true`, the same answer it gives a fully verified pair. A stamp is a PAIR. Both halves absent is the legacy shape: metadata written before stamping existed, which cannot be verified either way and is accepted deliberately, because failing it closed would mark every pre-existing bridge incomplete until re-synced. Exactly one half present is not that. Something wrote a stamp and did not finish, which is precisely the condition stamping was added to detect — so the check handed back "verified" for the one shape that most deserves suspicion, and a cross-repo impact query built on it would report a confident answer about a database its metadata cannot vouch for. The two states are now separated: neither half present accepts, exactly one rejects as provenance-unknown, both compare against the file as before. Found by the repository's own contract check, not by the plan. Mutation-verified: restoring the `||` form turns both half-stamp cases red while the legacy and fully-stamped controls stay green, so the pair genuinely pins the distinction rather than passing either way. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): pair unstamped bridge metadata by write order, before any open Unstamped metadata was waved through: `bridgeMetaMatchesFile` returned "matches" for any pair with no stamp to check, so the stale-meta-beside-a-new-database window stayed open for every bridge written before stamping existed, and `runGroupImpact` spent that metadata's completeness as fact. `writeBridge` renames the database into place and writes the metadata after, so `meta.mtime >= db.mtime` holds for any pair written together — including by builds that predate the stamp. A database strictly newer than the metadata beside it can only come from a swap whose metadata write did not land. That is the fallback now. It is a heuristic on write order, not proof of provenance, and it is wrong in two directions: a stale metadata file touched after the swap still reads as paired, and a pair whose clock stepped backwards between the two writes reads as unpaired. Both are recorded at the code; the second is the safe direction. Equality counts as paired, or a coarse-granularity filesystem would reject every legacy bridge for a reason that is about the filesystem. The verdict is now taken in `ensureBridgeReady` BEFORE the database is opened, and carried on the metadata rather than recomputed afterwards. That ordering is load-bearing, not tidiness. Impact and trace both open the bridge and only then ask about provenance, so on any platform or LadybugDB build where a read-only open advances the file's mtime, every pre-stamp bridge would report provenance-unknown from its first query onward — the exact repo-wide regression this rule was chosen to avoid, arriving as a silent downgrade rather than an error. It does not happen on Linux, which was measured. It cannot be measured on Windows: pinning it by really opening the database needs an in-process write→read reopen of the same bridge.lbug, which is a documented limitation there. Rather than ship a Windows-skipped test and leave the assumption unverified on the platform whose file semantics are most likely to differ, the check moved ahead of the open so no platform has to be trusted. The new guard forces the hostile case on every platform: the open is stubbed to advance the database's mtime, and the verdict must still be "paired". It is registered in the cross-platform list so the Windows and macOS shards run it, and it has a control so it cannot pass vacuously. Two existing fixtures mocked `readBridgeMeta` to return a stamped-era version while never writing a meta.json — a state production cannot reach, since a non-zero version can only come from a file that exists. They now write the metadata their own mock claims to have read, rather than the helper being loosened to accept metadata it cannot stat. Mutation-verified twice: reverting the write-order branch turns both rejection cases red while all four legacy-accept cases stay green, and moving the pairing call back after the open turns the ordering guard red on its own. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(group): compute cross-repo completeness in one place Three surfaces can return a partial cross-repo answer — impact, trace, and the contract listing — and each decided for itself whether it was complete. Impact carried the structured triple; trace said it in prose, if at all. An agent reading a not-found trace had no machine-readable way to tell "there is no path" from "there may be a path in a repo this sync could not read", which is the difference between an answer and a floor. `crossRepoCompleteness` is now the one computation, and its input deliberately does not name where any of it came from. `BridgeMeta` is not in the signature and must not be: `groupContracts` answers the same question from contracts.json and never opens a bridge, so `version`, `repoListsUnreadable` and `pairedWithDatabase` do not exist on that path. Each caller derives its own `provenanceUnknown` — the bridge callers through `bridgeProvenanceUnknown`, which stays separate for exactly that reason — and passes the boolean in. Scope arrives as a predicate rather than a repo list or a subgroup, so narrowing a query's scope stays a change to one argument at the call site. The trace results now carry `truncated` / `truncationReason` / `riskEpistemic` like impact does. `notes` is untouched; it remains an addition to the machine channel, never the channel. One correction to the approach as written: it said to pass the trace's two endpoint repos as the predicate, but a destination trace declares no `to`. It asks where a call lands, so any member may hold the answer — and an unreadable provider repo is precisely how "no outgoing ContractLink leaves this repo" becomes a wrong answer rather than an empty one. Filtering that path to the `from` repo would have reintroduced the bug this unit exists to close, so it passes every repo and a test pins it. Two pre-existing paths become consistent with the vocabulary as a result: a crossing-capped result now reports `truncationReason: 'partial'` alongside the `truncated` flag it already set, and the destination path's `ambiguous` returns now report the cap its `ok` and `not_found` siblings already reported. Both are additive — no field is removed, and no `truncated` flips from true to false. `truncationFields` returns a discriminated union now, so `truncationReason` reads without a fallback on the branch where it cannot be absent. Mutation-verified: reverting the provenance fold alone — one line in the shared helper — turns 8 tests red across both surfaces, 2 new trace scenarios and 6 existing impact ones, which is the point of there being one helper. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): narrow the incomplete-repo set to the query's declared scope A subgroup-scoped impact query was marked a lower bound by repos it had explicitly excluded. The fan-out already drops every neighbour outside the subgroup, so those repos could not have contributed a crossing to the answer — and a completeness marker that fires on results it does not describe is how a caller learns to ignore the marker. The scope is the query's DECLARED one, not the one the walk reached. An incomplete repo's contracts are absent from the bridge by definition, so it is never in the traversed set; filtering on what was traversed would empty the intersection on every query and silently restore the fail-open this channel exists to close. Declared scope here is the subgroup PLUS the query's own repo, which the approach did not account for. The walk starts from that repo's contracts in the bridge, so when it is the repo the sync could not read there are no crossings to find under any scope — and a subgroup excluding it would have turned that vacuum into a confident "nothing depends on this", for a tool an agent uses to license a delete. That case reported a floor before this change, so narrowing to the subgroup alone would have been a regression. The union only ever widens the in-scope set, so it cannot re-mark a repo the query excluded. Membership goes through the existing `repoInSubgroup` in both clauses, `exact` for the origin equality, rather than growing a second notion of what it means for a repo path to be in scope. Sound only while `MAX_SUPPORTED_CROSS_DEPTH` is 1 — at depth 2 an out-of-scope repo can sit between two in-scope ones — and that constraint is recorded at the intersection. Unscoped queries are byte-for-byte unchanged: `repoInSubgroup` answers true for an absent subgroup, so the intersection is the whole set. Mutation-verified: restoring the unfiltered predicate turns exactly the two scoped cases red while the unscoped control and both in-scope guards stay green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): keep the preserved registry and the bridge from disagreeing A total-failure sync refreshed contracts.json's diagnostic lists and left meta.json alone. But meta.json, not contracts.json, is where runGroupImpact reads completeness from — so the registry said "this sync could not read app/backend" while a cross-repo query answered `{ cross: [], truncated: false }`. Two surfaces describing the same run, one of them wrong, and the wrong one is the machine-readable one an agent uses to license a delete. The preserve path now refreshes the same two fields in the metadata. The database stays untouched: it still holds the contracts being preserved, and rebuilding it here would be the one write that could lose them. Refreshing metadata is not free, though, and the obvious version of it is a fail-open. The rewrite moves meta.json's mtime to now while bridge.lbug's stays old, so an unstamped pair whose database is NEWER than its metadata — the shape the write-order rule exists to reject — would come out of a preserve sync passing the check. Writing "no stamp" does not help; the write-order comparison is exactly what the moved mtime defeats. The verdict has to be recorded in the metadata, because the refresh cannot avoid moving the mtime. So `provenanceUnknown` is persisted whenever the existing pair does not already check out, the existing stamp fields are carried through verbatim rather than dropped, and `bridgeMetaMatchesFile` rejects the marker ahead of both the stamp and the write-order heuristic. A pair that already matched is re-stamped instead, which also upgrades a legacy unstamped-but-paired bridge to an exact stamp. No preserve run can increase the number of pairs that pass the check. The marker self-clears: `writeBridge` builds fresh metadata and never sets it. `BridgeMeta` carries two reader-side fields documented as never persisted, and this is the first code in the repo that reads metadata and writes it back. Both are stripped explicitly before every write. `pairedWithDatabase` is the dangerous one — persisted, it would tell every future reader the pair had been verified — and a test seeds both on disk to pin that neither survives. The write is not wrapped in a catch, unlike writeBridge on the success path. There contracts.json is canonical and already written, so a stale bridge is a recoverable degradation; here the write IS the guard against a confident wrong answer, and swallowing its failure would reinstate the fail-open it closes. `writeContractRegistry` above is unguarded into the same directory for the same reason. A group with neither file writes nothing: `readBridgeMeta` already answers `version: 0` for an absent file, so a written one would say what the absence already says while inventing state for a bridge that has never existed. Mutation-verified three ways: dropping the marker write turns 6 red including both laundering scenarios; moving the marker check below the stamp branches turns the unstamped-laundering case red; removing the field stripping turns the never-persisted test red. Each restored byte-exactly and re-verified. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): report group_contracts' completeness in the shared vocabulary `group_contracts` returned contracts and cross-links and said nothing about whether that listing was the whole story. An agent reading it after a sync that could not open half the group got a confident-looking list with no way to tell it was a floor — the same fail-open the impact path already closed, on a surface that had no channel for the answer at all. It now returns the registry's two diagnostic lists and the structured triple, folded through the same helper the impact and trace surfaces use, so the three cannot drift. The helper takes no `BridgeMeta` precisely so this path — which reads contracts.json and never opens a bridge — can share it. The three registry states stay distinguishable, which is the point: - key absent: the registry predates the field and has no opinion about which indexes opened, so the key is omitted rather than invented as `[]`, and the listing reports a floor. It cannot say which repos the sync failed to read, so it cannot claim to be complete. - key present and empty: measured, clean, not truncated. - key present and populated: the repos, and a floor. `incompleteRepos` is dropped on this surface alone: both lists it derives from are returned verbatim beside it, and a third name for the same repos is drift waiting to happen. The import is lazy, matching `groupImpact` and `groupTrace` in this same class. `cross-impact.js` statically pulls the native LadybugDB binding through `bridge-db.js`, and `service.ts` is loaded by every `gitnexus group` subcommand including ones that touch no database. One fix inside the same file that this unit forced: the registry loader gated `missingRepos` with a bare `Array.isArray`, which admits `[{repo:'x'}]`. That was inert while nothing read the list, but this change both returns it and folds it into the completeness answer — so an unreadable value would have been printed as a repo name and would have flipped `truncated` on garbage. It now uses the same `recordedRepoList` gate `group status` already applies to the same field. `missingRepos` has always been required, so unlike `unreadableRepos` it has no "not recorded" state to preserve and an unreadable value degrades to empty. Mutation-verified: reverting the fold alone turns 14 tests red and leaves the control — the contract and cross-link payload this tool has always returned — green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(cli): stop dropping group contracts' completeness fields on the way out `group contracts --json` destructured `{ contracts, crossLinks }` from the service payload and rebuilt an object from just those two. Everything else the service returned was discarded on the way to stdout — so the completeness fields the MCP tool now carries were invisible at the CLI, and the two surfaces disagreed about the same registry. It prints the payload whole now. A field added to the service reaches `--json` without a matching edit here, which is the point: the re-serialized subset was a second place that had to be remembered, and it was not. The human-readable path gains the same signal in words. A listing built from a sync that could not read part of the group shows counts that are a floor, not a census, and it named neither fact. It now says so and names the repos when the registry recorded them — and says the sync did not record which repos it could read when it did not, because a listing that cannot say what it is missing is still incomplete. Mutation-verified: restoring the re-serialized subset turns the `--json` case and the control red. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): tell a missing registry entry apart from an unreadable one `group status` printed MISSING for both "this repo has no row in the registry" and "the registry itself could not be read", so an operator whose registry.json was corrupt was told every repo was unregistered — and sent to re-register them instead of to the one file that was actually broken. The two are now separate. `missing` keeps its old meaning and still flags every unusable repo, so an older consumer is unaffected; `unresolvable` is additive, always present, and carries the reason that produced it. This is the one caller that has to make that distinction, so it takes the strict global-registry read. `readRegistry`'s `catch { return [] }` collapses a malformed registry into an empty one, which is indistinguishable from a genuine absence and is exactly what produced the wrong label. The cost is accepted knowingly and recorded at the call site: the strict read rejects the whole registry when any row fails to identify a repo, so one malformed row renders every member unresolvable — including members whose own rows are fine. That is the honest verdict, and it is reported as an unresolved state rather than a clean one. Choosing between the two labels needs to know whether a row exists at all, which `registryIdentifies` answers by mirroring the two tiers the resolver matches a bare group-config value on — registry name, case-insensitively, and repo path. It deliberately stops short of the hashed-id and partial-name tiers: those exist to be generous about what an operator typed, while this only picks a label, and a looser match would relabel a genuine registry miss as an unresolvable row — the same conflation this change removes, pointed the other way. The plan's third failure mode — a row that resolves but whose storage path cannot be opened — turns out to be unreachable: `loadMeta` returns null on every error and `checkStaleness` catches everything, so nothing after `resolveRepo` inside the try can throw. The reachable per-repo case is `resolveRepo` itself throwing, as it does for two registered clones sharing a name, and that is what the tests drive end to end through the real CLI. The code still handles the plan's case correctly if those helpers ever start throwing. Mutation-verified: reverting the split turns 6 unit and 2 CLI cases red while both controls — a genuine miss, and a healthy group — stay green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(cli): say what the preserve path actually does to contracts.json The sync summary announced "Did NOT write contracts.json" on the branch that writes it. The preserve path rewrites the file — keeping the previous sync's contracts and cross-links, replacing only the two diagnostic lists — so an operator who checked the mtime and found it moved was told the opposite of what had happened, on the command this PR exists to make legible. It now says the previous contracts were kept and names what changed. The no-prior-registry branch is narrowed for the same reason. It claimed nothing at all was written, and that is no longer true either: this path still records the run against an existing bridge's metadata. The claim is now scoped to contracts.json, which is the file it can actually speak for. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): stop the total-failure log promising a preservation that did not happen The warning fired before the prior registry was read, so it could only ever promise one of the two things that might be true — and it promised the wrong one to every group that has never synced: "keeping the contracts from the previous sync" about a file that does not exist. The console line for that same run, driven by `registryOutcome`, said the opposite. It now lives inside the branch, after the read, with one message per outcome chosen at the point the outcome is decided. The log and the console cannot disagree, because the same fact selects both. Both messages keep the warn level and the two repo lists. Mutation-verified: reverting the split turns the no-prior-registry case red while the preserved case — whose claim was already true — stays green. The dry-run test's log filter was also widened to the sentence both messages share, or the new wording would have made that assertion match nothing and pass regardless. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): make the bridge-failure warning describe what the code guarantees The warning after a failed `writeBridge` promised that cross-repo impact would report `truncated` until a sync succeeded. Nothing on that path produces that signal. The swap is the last step: `writeBridge` builds the new database in a staging directory and only then moves the old one aside. A failure during the build therefore leaves the previous sync's `bridge.lbug` exactly where it was, beside the `meta.json` stamped for it — a pair that passes `bridgeMetaMatchesFile` with the previous run's `unreadableRepos`. The next cross-repo query answers `truncated: false` from superseded contracts, which is the opposite of what the operator was told to expect, and worse than being told nothing. The warning now says what is actually true: contracts.json is intact and canonical, the bridge was not replaced, cross-repo queries may still answer from the previous sync's contracts, and nothing marks them as superseded. The metadata is deliberately NOT re-stamped to make the original promise true. That would recreate exactly the metadata/database mis-pairing the stamping on the preserve path exists to prevent, and the comment at the warning records it. The claim is asserted against captured log output rather than left to the state tests. Those check which pairs match and what the preserve path writes; every one of them stays green while this sentence reverts to promising a truncation. An unasserted user-facing branch is the defect class this change is closing, so it does not get to close it while remaining one. No filesystem shape makes the real `writeBridge` fail while `writeContractRegistry` succeeds — they write into the same directory one line apart — so the failure is armed through a pass-through wrapper on the file's existing mock. It delegates byte-for-byte unless a test arms it, and is reset around the new suite. Mutation-verified: restoring the original wording turns its own assertion red and nothing else. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(mcp): name every registry outcome group_sync can actually return The tool's description told agents `registryOutcome` is 'written' or 'preserved'. It has a third reachable value: 'no-prior-registry', returned when nothing could be read AND there was no previous contracts.json to carry forward. An agent calling this tool against a group that has never synced got a value its own tool description said did not exist, and no way to tell it apart from the case where the previous contracts survive. The distinction is the whole point of the value. After 'preserved' there is a registry to read — stale, but real. After 'no-prior-registry' there is nothing on disk at all, so a following group_contracts or group_impact has no registry rather than an old one. Those need different responses from the caller. 'not-attempted' stays undocumented because it is unreachable through this tool, and a guard asserts it stays that way. The code comment above the annotations claimed the preserve path does NOT write contracts.json. It does — it rewrites the file, keeping the previous contracts and cross-links and refreshing only the two diagnostic lists, which the CLI's own summary was corrected to say a few commits ago. Left alone it would have re-seeded the same wrong claim next to the text that now states it correctly. Mutation-verified: deleting the 'no-prior-registry' sentence turns the guard red. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(mcp): explain structural incompleteness on the impact tool and status resource The impact tool's GROUP MODE paragraph described one cause of truncation — the fan-out running out of room — and left an agent to assume that was the only one. So a `truncated: true` carrying `truncationReason: 'incomplete-sync'` read as "retry with a smaller scope", when retrying returns the identical floor forever: the repos are absent from the bridge itself, and only a re-sync puts them back. The old text also said the response carries the truncation fields "when it stops early", which is wrong for that case — `truncatedRepos` names repos even when ZERO crossings to them were attempted, because their contracts were never in the bridge to cross to. The paragraph now branches on the reason and gives each its remedy: 'timeout' and 'partial' are runtime limits where a retry or a larger budget can help; 'incomplete-sync' is structural and the remedy is `group_sync`. The reason union is now derived from an exported `as const` array rather than written as a bare type. A type-only union gives a guard nothing to enumerate, so the guard has to hand-list the members — and then it passes forever the moment a fourth is added, which is the exact regression it exists to catch. The guard iterates the runtime array instead. Verified by appending a probe member and watching it go red, then removing it. The resolved type is unchanged; every importer uses `import type` and none needed an edit. The status resource said "Group index / contract staleness" and nothing about the distinctions its payload now carries. It explains all of them: a repo absent from the registry versus one whose entry could not be resolved, and the `unreadableRepos` tri-state where an ABSENT key is not an empty one — absent means the last sync never recorded what it could read, so cross-repo answers for that group are a floor. The description an MCP client actually receives lives in `getResourceTemplates`, not in the context resource's inventory line the plan pointed at. Both now carry the vocabulary, so the two surfaces cannot disagree about the same payload. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(group): serialize group syncs behind a fail-closed per-group lock Two concurrent syncs of one group could lose one another's writes. Both read the prior registry, both built contracts, both wrote — last writer won, and the loser's work was gone with nothing reporting it. A group sync is long and expensive and is exactly the operation whose lost update destroys contracts. `syncGroup` now takes a lock for the whole persist section, acquired exactly once. `acquireIndexLock` is not reentrant, so a second acquisition anywhere below would deadlock the happy path rather than an edge case; `withGroupSyncLock` has one call site and nothing inside it re-acquires. The lock lives on a dedicated `sync-lock` directory inside the group directory, mirroring the registry lock's dedicated directory rather than reusing the resource's own — a lock directory that could collide with a per-repo index slot repeats a bug the registry lock's comment already warns about. It fails CLOSED, which is the opposite of `withRegistryLock` and deliberately so. That one degrades to unlocked because it guards a sub-second JSON merge on a latency-critical path; here running unprotected is the outcome the lock exists to prevent. Three exits are covered: a timeout, an unwritable lock directory, and the lock-free degradation the primitive performs silently. That third exit needed a change in `index-lock.ts`, and it is the one declared exception to keeping this work inside core/group/. `acquireIndexLock` answers a read-only or permission-denied filesystem with a no-op handle that is byte-identical in shape to a real one, so a caller for whom lock-free is not an acceptable outcome could not tell the difference. It now carries an optional `lockFree` marker. The change is additive by construction: no signature moves, no control flow changes, nothing about when or how a lock is taken changes, and every caller that ignores the field behaves exactly as before. A filesystem probe inside the group module was considered and rejected on evidence: `selectBackend` returns `socket` on Linux and Windows, where `acquireViaSocket` never touches the filesystem and this branch cannot occur — so a probe would refuse syncs on the two platforms that never degrade while missing the one that does. The timeout ceiling is a named 600s constant passed explicitly. The magnitude matches the primitive's own analyze-sized default because a group sync is analyze-shaped and a legitimately queued second sync must be able to wait out a full first one. Passing it explicitly is about the override, not the magnitude: `resolveTimeoutMs` resolves `GITNEXUS_INDEX_LOCK_TIMEOUT_MS <= 0` to Infinity, which would turn fail-closed into a hang. Cross-process exclusion is proved with a real spawned holder, not an in-process mock, which cannot demonstrate the property this exists for. The lock-free scenario pins `GITNEXUS_INDEX_LOCK_BACKEND=file` — unpinned it would pass on two of three platforms while measuring nothing — and produces the failure by injecting EACCES on one syscall rather than by chmod, so it runs identically on Windows instead of being skipped there. The CLI reports the failure through pino rather than a bare stderr write, which this package lints as an error to keep that migration moving, and the test reads the `msg` field rather than a raw substring — matching on the raw text would have passed only by accident of quoting and would go green again if the line were downgraded. Nothing is skipped on any platform, and the test is registered for the cross-platform shards. Mutation-verified: removing the lock acquisition turns 6 scenarios red; removing the lock-free rejection turns the degradation scenario red on its own. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): make the sync-lock timeout name a cause it can establish The fail-closed lock surfaced the primitive's own timeout message to users for the first time, and that message says the wait was on "another gitnexus analyze" — a cause its detection path cannot establish. It is the same confident-about-what-it-could-not-determine claim this PR exists to remove, inherited rather than written. The wrapper now throws its own. It names the group, the lock directory, the operation, and the elapsed wait, and it says plainly that nothing was written. The holder clause branches on `holderKnown`. The socket backend exposes no owner metadata and reports a placeholder pid of -1, so on that backend — and on the file backend's malformed or vanished-lock timeouts — the message says the lock stayed held but the backend cannot identify who held it, rather than printing a pid that means nothing. The elapsed wait is measured by the wrapper. `IndexLockTimeoutError` carries only `holder` and `holderKnown`; the figure exists solely inside the string being replaced, so it had to be taken rather than read. One pre-existing assertion changed with it: the timeout case asserted `'Timed out after 600000ms'` from the inherited text, which is precisely the message this replaces. Mutation-verified: restoring the inherited message turns the three assertion cases red and leaves the control — a real acquisition that succeeds — green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): stop a losing sync from downgrading the one that beat it to the lock Serializing is not ordering. Both syncs run extraction outside the critical section, so a total-failure sync that acquires second reads the winner's fresh registry as `prior` and rewrites it with all-unreadable lists. The lock alone does not prevent that — it only decides who goes second, and the loser then overwrites a healthy registry with a description of its own failure. Deterministically, not as a rare interleave. The guard is a compare-and-swap on the registry file's own identity: stat before acquiring, re-stat after, and write nothing when they differ. Identity is presence plus size, mtime and inode — `writeContractRegistry` publishes through write-then-rename, so a real replacement always changes the inode even if size and mtime happen to collide. Deliberately NOT keyed on `generatedAt`, for two independent reasons. It is stamped when the registry object is built, before the lock is acquired, so a winner that waited would write a value older than the loser's start. And the preserve path carries it forward verbatim by design — it dates the contracts, not the write — so after any preserve sync it does not date the write at all, leaving the comparison blind on exactly the pairing this guards. A file-identity compare also needs no cross-process clock agreement. The skip reports the existing `preserved` outcome. Nothing was written and a prior registry was kept, which is what that value already means; a new one would falsify the guard asserting the sync tool's description names every reachable outcome, and would fall through the CLI's outcome chain, which has no fallback. The bridge metadata refresh is skipped too, which the plan did not specify. `refreshPreservedBridgeMeta` stamps THIS run's repo lists into meta.json, and meta.json is where cross-repo impact reads completeness — so writing it would report as unaccounted-for exactly the repos the winning sync had just accounted for. That is the same downgrade being refused, one file over. Skipping both is what makes `preserved` an honest answer here. Mutation-verified: removing the after-stat and the skip turns the three decisive cases red while both non-misfire controls stay green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(group): run the bridge swap inside the caller's critical section The bridge swap needed the group lock, and could not take it: `syncGroup` already holds it when it calls `writeBridge`, and `acquireIndexLock` is not reentrant. Acquiring inside the swap would deadlock every sync on the happy path rather than on an edge case. So the body splits the way this repo already splits this shape — a lock-free `writeBridgeUnlocked` whose precondition is that the caller holds the lock, and a thin `writeBridge` wrapper that acquires it for direct callers, mirroring `registerRepoUnlocked` / `withRegistryLock`. `syncGroup` calls the inner one; everything else keeps calling `writeBridge` and is now serialized by it. `writeBridge`'s exported signature is byte-identical to before, so no caller changed and nothing about the exported surface moved. The precondition is enforced by a comment naming the single production call site, which is what the existing precedent does. A type could carry it, but the repo's own answer to this question is a comment, and diverging here would make this the odd one out for no additional guarantee. `refreshPreservedBridgeMeta` is deliberately left unsplit. Its one caller is already inside the critical section and it has no test callers, so an acquiring wrapper would be dead code standing in for a guarantee the caller already provides — and moving the lock inside it would be the second acquisition this change exists to avoid. Scope: this delivers writer-writer exclusion only. The reader-side promotion of a leftover `.bak` into place runs on ordinary reads, outside any lock, and is not claimed here — the pairing check remains the reader's defense. Confirmed as live behavior while writing the crash-recovery test, which asserts on file state rather than through `bridgeExists` for exactly that reason. One test file beyond the two the unit named had to change: a suite mocks `bridge-db` to inject a `writeBridge` failure and exercise the bridge-write warning. Once the sync calls `writeBridgeUnlocked`, that fault was being injected into a function the path no longer calls, and the test went red. The mock is repointed. Mutation-verified three ways. Pointing the sync back at the acquiring wrapper deadlocks a single UNCONTENDED sync — the evidence that the nesting defect is real and that this split is what prevents it. Removing the wrapper's acquisition turns the direct-write exclusion case red. Making the lock-free half acquire for itself turns the held-lock case red.

It matched on an end-anchored extension regex covering the JavaScript family, so most of what this repo tracks was never looked at: JSON, YAML, TOML, Markdown, snapshots, SQL, protobuf, the .NET project files, the shell and batch scripts. Worse, an extension regex cannot reach a file that has none. `Dockerfile`, `CODEOWNERS`, `LICENSE`, the husky hook and every bare dotfile were unreachable by construction — no amount of widening the pattern would have covered them — so a second basename filter had to exist for the claim to be true. It stays an allowlist rather than becoming "everything git tracks", because the repo legitimately tracks binaries whose extensions must stay out. The two filters together now collect every one of the 5000 tracked files except 31 — the 30 native prebuilds and one PNG — and those 31 are exactly the files that carry a NUL. The allowlist no longer has a gap that is not a genuine binary. The planted-fixture cases route through the collector's own predicate rather than straight into the scanner. The pre-existing fixture test bypassed the filter entirely, so it could only ever prove the byte locator worked, never that the collector would hand it the file — which is precisely how the gap survived. Mutation-verified both ways: removing the basename filter drops `.gitignore` and `Dockerfile` from the planted results, and reverting the extension regex drops `.json` and `.md`. One added case is a preservation pin rather than proof — that tracked binary formats stay out passes either way, and guards the allowlist from becoming a denylist later. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(hygiene): stop the byte guard reading the vendored grammar tree Widening the guard to every tracked text format also pulled in the vendored tree-sitter grammars, and those are where the bytes are: four generated `parser.c` files come to 62 MB between them, Kotlin's alone 33.7 MB. Excluding that root drops 76 files but 66% of the bytes the scan reads — 97 MB down to 33 MB. The exclusion is a single anchored prefix, matched case-sensitively with `startsWith`, and both halves of that matter. A `vendor` path-SEGMENT match would also drop first-party fixtures this repo tracks under directories named `vendor` and `Vendor` — a Kotlin one, a PHP one, and three files under gitnexus-web — silently narrowing coverage while the assertion pinned the loss in place. Case-insensitivity would do the same to a `Vendor` directory at the excluded root's own level. The root is named in the guard itself, so the claim that it covers every tracked text file stays honest about the one place it deliberately does not look. The cost comment was wrong and is now measured rather than estimated. It said "the scan is ~10 ms" — ambiguous between locating the byte and reading the files, and stale in its byte basis. Locating is ~14 ms; the reads dominate it by two orders of magnitude, which is the actual reason for the concurrency pool and the actual reason this exclusion is worth having. Every figure was re-derived from the finished file rather than carried over from a draft. The header's claim that `git ls-files` "never descends into vendor" was already false — vendored code is tracked, so all 106 of its files were being reported and read. Corrected here, where the distinction becomes load-bearing. Registered in the cross-platform list first and given a shard weight second. The weight table is only consulted for files already in that list, so a weight entry alone is inert and the shard test filters unregistered keys without complaining. The three-way split stays within 1.01x of ideal. Mutation-verified three ways: a case-insensitive segment match, a case-sensitive segment match, and a case-insensitive anchored prefix each turn an assertion red. The casing half was initially unfalsifiable — nothing tracked is named `gitnexus/Vendor/`, so a tracked-set assertion could not distinguish it. Rather than leave the claim unpinned or invent a fixture, it is pinned on the predicate with a synthetic path; the tracked-set assertions pin the anchoring. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(group): make the strict-read test able to see which read ran The file bound both registry exports to one mock: readRegistry: (...args) => readRegistryMock(...args), readRegistryStrict: (...args) => readRegistryMock(...args), so the case named for the strict read asserted a behavior it could not attribute. Point the production call at the lenient export and every assertion still holds, because the mock answers the same way whichever one is called. That is not a hypothetical. With this file as it was, and `syncGroup` mutated to call `readRegistry` instead of `readRegistryStrict`, all 32 tests passed — the suite was blind to the exact substitution it exists to prevent, and the fix it guards could have been reverted without a single red. The exports now have separate mocks: the lenient one always resolves an empty list, which is its real contract, and only the strict one is armed by the cases that need a failure. The named case also asserts directly that the strict read was called and the lenient one was not, so the attribution is explicit rather than implied by an outcome. No tests added — the unit is about what the existing ones can see. Mutation-verified: the same substitution now turns 24 cases red, including the named one, and everything stays green unmutated. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(group): pin the CLI output branches this PR introduced The three sync outcomes and the status table's new labels had no assertions. Every one of them is a sentence about what happened on disk, and this PR corrected several that were false — a preserve branch that announced it had not written the file it rewrites, a status table that called an unreadable registry a missing entry. Text that describes state, with nothing pinning it, is how those got wrong in the first place. Six cases drive the real CLI end to end, through the two shapes that need no indexed repo: members absent from the registry, and members registered at a storage path with no index file, which makes every repo unreadable. The file header claimed no LadybugDB-backed command was driven end to end; that is no longer true and it now says so. Each branch was suppressed in turn and its assertion goes red — all five that the plan named. One of those mutations first reported PASS, and the cause is worth recording: the string being suppressed also appears inside a neighbouring branch's comment, so the harness silenced the wrong line. That is a bad mutation, not a weak test. The harness now asserts the marker it suppresses is unique before trusting the result, and the redone check goes red. The plan's sixth scenario is already covered by an existing case that asserts both labels in one table, so it is not duplicated. A seventh case was added beyond the plan: without a populated-list case, "prints neither line" would pass just as well against a CLI that never printed that line at all. Adds about 15s of measured spawn time locally; CI runs these against the built dist, which is materially faster per spawn. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(group): assert the MCP payloads by exact shape, not by partial match Nothing asserted what the group tools actually return. The sync response's unreadable list and registry outcome, and the contract listing's incompleteness fields, are documented in the tool descriptions an agent reads — and could have been dropped in a refactor without a single test noticing. The assertions are exact-shape rather than partial. A `toMatchObject` would let a dropped key pass, which is precisely the regression these exist to catch: the failure mode is an absent field, and a partial match is defined not to see one. Absences are additionally asserted explicitly. The tri-state has to survive the response boundary, and it is the reason exact shape matters here more than usual. An absent `unreadableRepos` means the sync never recorded what it could read, so the listing is a floor; an empty list means it measured none; a populated list names them. Collapsing absent into empty turns "we do not know" into "we checked, it is fine" — so a mutation that replaces the conditional spread with `?? []` is covered specifically, not just the outright deletion. Mutation-verified per field: removing either sync forwarding line, deleting the conditional spread, replacing it with the invent-empty form, dropping the truncation triple, or hardcoding the provenance flag each turns an assertion red. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(group): stop the bridge input narrowing what unreadableRepos means The same field had three definitions. The registry and the bridge metadata both say it covers a repo this sync could not extract from — an index that would not open, or an extractor that threw partway through, one bucket because the consequence is one thing. The bridge input said only "whose index could not be opened", which describes one cause and silently excludes the other. It now points at the registry's definition instead of restating it a third time. A definition written once and referenced cannot drift; three copies of it already had. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(group): record what the mtime pairing does and does not prove The write-order fallback is a heuristic standing in for provenance, and a future reader deciding whether to lean on it needs to know where it breaks before they do. Both directions are now stated where the function is read rather than only in the plan that introduced it. The false-accept direction is a non-monotonic wall clock — mtime is realtime, so an NTP step back, a snapshot restore, or container skew between the two writes can leave a mis-paired set reading as ordered. Coarse filesystem granularity is explicitly called out as NOT being that hazard, because it looks like it: it collapses a pair written together to equal times, and equal is accepted, which is the right answer for that pair. The false-reject direction is any copy or restore that rewrites the database's mtime after the metadata's. An intact legacy pair is demoted to a lower bound and stays there until a sync re-stamps it, because nothing on the read path can tell it apart from the swap window it imitates. That second direction corrects a claim made while planning this work: that the rule could only ever demote pairs already broken. It cannot. `cp -r` and `rsync` without timestamp preservation both produce it on a healthy group, and saying otherwise where the code is read would leave a future reader to discover it the hard way. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(storage): stop a corrupt registry quoting its own bytes into errors `JSON.parse`'s SyntaxError embeds a window of the source around the failure — V8 gives exactly ten characters either side — and the strict read rethrew it untouched. The registry persists HTTPS remote URLs with their userinfo, so a file that breaks next to one puts the credential into the error: Unexpected token 'L', ..."end.git"},LEAKCAN4RY"... is not valid JSON The parse now has its own guarded region and reports the path and the failure class, matching the two corrupt-registry errors already in this function. The original error is discarded — not logged, not attached as `cause`. This codebase's convention elsewhere is to hand the logger the Error so it captures stack and cause, and following that convention here is precisely what would put the byte window into the log. Under MCP stdio that log is written to the client's log file on disk, so the thrown-error channel was never the only one that mattered. The `catch` takes no binding, so the error cannot be reused by accident later. That was not theoretical: a sibling commit routes this message into `unresolvableReason`, which `group status` returns to MCP clients and prints in the CLI table. Every channel was traced — throw, cause, inspect with the full chain, the logger, and both downstream consumers. The leaking shape is narrower than it first appears, and worth recording. The windowed message only fires when the parser fails at a value-start or trailing position; a break inside a quoted string yields an unterminated-string error carrying no window. So a plain mid-URL truncation does not leak — a short write landing over a longer one does, leaving a URL fragment where a value was expected. That is a reachable shape for the one machine-wide file every gitnexus process writes. The test asserts the message still names the path and the corruption class, not only that the secret is absent. Asserting absence alone would stay green if the message became empty. Mutation-verified: restoring the raw rethrow brings the token back verbatim. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(storage): drop the stale lenient call-site count The docstring said keeping `readRegistry`'s signature untouched leaves "its nine other call sites" unaffected. There were thirteen when the discrepancy was noticed and fourteen by the time it was fixed. The same figure appeared in the test file's header. Replaced rather than corrected. A count in prose next to code that moves is a claim that goes stale without anything failing — which is the defect class this change set exists to remove, so re-seeding a fresh number would be repeating it with a longer fuse. The argument was never about the quantity: leaving the signature alone keeps every lenient caller provably unaffected whether there is one or fifty. Also withdrawn while here: the claim that the bridge schema-version guards diverge between call sites. They do not — the two forms are complements for every value a writer can produce, there are three sites rather than the two claimed, and all three agree. Recording a divergence that does not exist would leave a future reader chasing it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(group): add an auditable finding-to-commit map The Definition of Done claims every review finding has exactly one commit and that reverting it reintroduces that finding and no other. Without a map that claim is only checkable by whoever holds the review report, which is one person for a short time. The map lists all 28 primary findings against their commits, the three findings whose suggested fix was deliberately not implemented and what shipped instead, and the four defects found while executing that no reviewer raised. It also records the revert contract honestly. Revertability is dependency-aware, not absolute: the shared completeness helper has three consumers, so reverting it alone does not build. That coupled set is named rather than left for someone to discover mid-revert. Two sections exist because the work produced them, not because the plan asked. Six claims in the plan turned out to be contradicted by the code — among them a scope predicate that would have reintroduced the bug its unit was closing, and an assertion about the mtime rule that was simply wrong. Recording only the findings would leave the impression the plan was followed as written. Five residual risks are listed for the same reason, including that R14 is not met on this PR: the diff attribute works locally but GitHub reads it from the base side, so this PR's own sync.ts stays binary in the web view and every PR after it renders as text. Not under docs/ — that path is gitignored, so a map written there would never reach the PR and the audit it exists for could not be performed by anyone else. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): read a version that is not a version as no provenance Raised by the check bot on this PR, and real — the bot found one symptom of it; the field splits four gates apart, not one. `readBridgeMeta` accepted any numeric `version`, and `0` is this file's word for "no provenance". A parseable but impossible value — negative, fractional — is not a schema version, and each gate that reads the field disagreed about it: ensureBridgeReady `> 0 && !== CURRENT` → opens the bridge openBridgeDbReadOnly `> 0 && !== CURRENT` → opens the bridge bridgeExists `=== 0 || === CURRENT` → says it is not there bridgeProvenanceUnknown `=== 0` → reports the answer complete Four verdicts about one file, and the last one is a fail-open of exactly the class this PR exists to close: a bridge nothing can vouch for, reported as fully accounted for. The suggested fix was to widen the provenance check to `<= 0`. That closes the reported symptom and leaves `bridgeExists` still disagreeing with both openers, so it is fixed at the reader instead: a version that is not a positive integer normalizes to the sentinel the gates were all written against. One change, four gates agreeing by construction, rather than teaching each of them the same new case and hoping the fifth reader remembers. Infinity is covered too, though by the pre-existing type check rather than the range one — JSON cannot carry it, so it arrives as `null`. Recorded at the test so the case is not mistaken for proof of the range check. Mutation-verified: restoring the loose numeric check turns the negative and fractional cases red. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): stop a malformed contracts.json reading as an unresolvable registry entry Raised by the check bot on this PR. Its stated mechanism was wrong — `loadMeta` returns null on every error and `checkStaleness` catches everything, so neither can throw — but its conclusion was right, and there is a concrete path it did not name. `readContractRegistry` is a bare `JSON.parse(content) as ContractRegistry` with no shape check, and the snapshot lookup guarded only the registry object: registry?.repoSnapshots[repoPath] The `?.` covers `registry` being null, not `repoSnapshots` being absent. A contracts.json without that field — a legacy file, a hand-edit, a truncated write — throws `TypeError: Cannot read properties of undefined`, which lands in the catch that labels failures as unresolvable GLOBAL-registry entries. So a group whose own contracts file is malformed reported every repo as a broken registry row, sending the operator to repair a file that was fine. An error from one cause presented as another, which is the defect this PR has been removing everywhere else. The optional chain closes the crash. The try is also narrowed to the call that earns the label: only `resolveRepo` sits inside it now, so "did not resolve" describes something that actually failed to resolve rather than whatever else happened to throw nearby. The comment records why the other two calls in that block cannot throw, so the next reader does not have to re-derive it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(group): give the completeness fold a module no native binding reaches The shared fold ended up in `cross-impact.ts`, which statically imports `bridge-db.ts` and through it the native LadybugDB binding. `groupContracts` therefore reached it through `await import('./cross-impact.js')` — loading that whole module graph to run a Set union and a ternary. Measured: 44-51ms and 8.4MB of RSS on first call, paid once per MCP server and once per `gitnexus group contracts` invocation. `completeness.ts` holds the vocabulary and the fold and imports nothing but types. `service.ts` imports it statically; the lazy import and the comment justifying it both go. `cross-impact.ts` re-exports so the three surfaces still have one import site for the vocabulary. Three other duplications collapse into the same move. `traceCompleteness` was hand-writing `{truncated, truncationReason, riskEpistemic}` — a third writer of the pair `truncationFields` exists to keep mechanically linked (#2787), in the file the consolidation had just touched. It calls the helper now. `recordedRepoList` existed twice, byte-identical, one copy's docblock saying it mirrored the other. That gate is the predicate the whole absent-vs-empty-vs-populated distinction rests on, applied to the same two lists on both the registry and the bridge — tightening one copy would have fixed one surface silently. One definition now. The trace's scope predicate compared repo paths with `===` while its sibling in `cross-impact.ts`, added in the same change, went through `repoInSubgroup` with a comment about not growing a second notion of membership. It had grown one: the helper normalizes separators and strips trailing slashes, so the same group.yaml spelling could be in scope for impact and out of scope for trace. Also here: `registryIdentifies` was a third, weaker copy of the registry's path rule — it skipped `realpath`, so a symlinked row would not match where the real resolver would. It uses `canonicalizePath`/`registryPathEquals` now. `contracts.json` is no longer respelled as a literal in `sync.ts`; `storage.ts` owns the name it reads and writes. And the runtime-truncation predicate is bound once instead of written out at both the flag and the reason, where forgetting the second would label a retry-able answer `incomplete-sync`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(group): give the lost-the-race sync its own outcome instead of overloading preserved A sync that finds contracts.json replaced while it waited for the lock reported `registryOutcome: 'preserved'`. That value already meant something else, and the two differ in exactly the thing the value is for: `preserved` rewrites the file with this run's diagnostics; this path does not touch it and deliberately does not record them. So both surfaces stated something false about disk. The tool description told agents `preserved` means "contracts.json was rewritten ... refreshing only missingRepos/unreadableRepos to describe THIS run (the file changed)". The CLI said "only the unreadable/missing repo lists were refreshed to describe THIS run". On the lost-race branch nothing was written and the log line beside it says so outright. That is the defect class this whole change set removes, reintroduced by the change set itself — and the reasoning recorded at the time makes it worse, not better: a new value was rejected because it "would fall through cli/group.ts's outcome chain, which has no fallback branch". A renderer limitation decided a domain value, and the description then had to cover two states with one sentence that fits one of them. `superseded` is its own outcome now, described in its own words to agents and rendered in its own words at the CLI. The registry on disk is FRESHER than this response's diagnostics, which is the opposite of every other non-written outcome and is why an agent needs to tell them apart. The CLI renders from a `Record` keyed on the union, so the next outcome fails the build here rather than printing nothing — the gap that made folding the state in look like the cheap option. The description guard is scoped per clause rather than over the whole string. It forbade "untouched" anywhere, which was right when one clause could only lie in that direction and wrong now that another clause is accurately untouched. It also asserts the superseded clause says so, or the two collapse back into one word for two states. Found by the quality pass over this branch, not by review. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(group): read bytes and stat through one handle, not two path lookups CodeQL flagged both sites as `js/file-system-race`, high severity, and it is right about the shape. `stat(path)` followed by `readFile(path)` is two independent path resolutions with a window between them — the classic check-then-use race. It also made the assertions weaker than they read. These two tests exist to prove a specific file was left untouched, and two lookups can land on different inodes, so "the bytes and the mtime are both unchanged" was not actually a statement about one file. The distinction is the whole point here rather than a technicality. `snapshotFile` opens the path once and takes both answers from that handle. The race is gone because there is no second lookup, and the assertion now genuinely concerns one inode. I had previously triaged these as below the ruleset's threshold and left them for the repository owner. That was wrong: they carry `security_severity_level: high`, and the branch ruleset gates on `high_or_higher`, so they were blocking the merge rather than sitting under it.

Resolve Java imports against parsed package declarations, expand package wildcards deterministically, and keep external imports unresolved when no in-repo package declares them. Co-authored-by: Gergo Magyar <gergomagyar0@gmail.com> Co-authored-by: Gergő Magyar <gergomagyar@icloud.com>	2026-08-15 11:53:28 +01:00
Gergő Magyar	28187bb3a7	fix(typescript): resolve imports against declared config, not path suffixes (#2953) (#2956) ... * fix(typescript): resolve imports against declared config, not path suffixes (#2953) TypeScript/JavaScript/Vue import resolution ended in `suffixResolve`, which answers "does any file in this repo have a path ending in this specifier?" and answers it by dropping leading segments until something matches. That is not module resolution, and it failed in both directions at once: - `@acme/telemetry/nest`, a registry dependency with no in-repo file, landed on the repo's only path ending in `nest/index.ts` — a false IMPORTS edge at confidence 1.0, indistinguishable downstream from a real one. The reporter measured 44 of 74 `apps/ -> packages/` edges landing on two such files. - `@repo/utils`, a first-party workspace package, resolved to nothing: its name lives in `packages/utils/package.json` and appears in no file path, so a path matcher cannot find it. Zero CALLS from 75 import statements. Both come from the same missing input — nothing read the config that says what exists — so both are fixed by reading it. Replaces the suffix matcher on this path with the algorithm tsc and Node actually run, in their order: relative/absolute, `#imports`, tsconfig `paths` (longest literal prefix wins, every target tried), tsconfig `baseUrl`, then the workspace package's own `exports`/`main`. A specifier none of those declare is external, and resolves to nothing. There is deliberately no fallback. New: - `typescript/tsconfig.ts` — every tsconfig/jsconfig in the repo with `extends` chains resolved, nearest-config-wins per file. The old loader read three filenames at the repo root, required `paths` to exist, and kept only `targets[0]` — none of which describes a monorepo, where `apps/web/ tsconfig.json` is what governs `apps/web/src/main.ts`. - `typescript/module-resolution.ts` — the algorithm. - `typescript/file-candidates.ts` — 11 TS-family extensions, replacing a shared 39-entry list spanning every indexed language, so a TypeScript import can no longer resolve to a `.py` file. - `import-resolvers/node-workspace-packages.ts` — in-repo manifests, with `exports` subpath maps, patterns, condition nesting, and the restriction that a package declaring `exports` exposes only what it lists. The per-pass `SuffixIndex` is gone from these three adapters: real resolution derives nothing from the file list — every candidate comes from a declared source and is checked with one `Set.has` — so there is nothing left to cache. Their `*-import-index-reuse` guards and the JS index-vs-scan differential are deleted with the mechanism they measured; the cross-language contract test moves the three languages to its existing `KNOWN_UNINDEXED` channel, and pins the exemption as a list so a fourth arrival is deliberate. Python, Ruby, Java, Go and the rest still route through `suffixResolve` and are untouched here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015Px638Zyqa9CJMUU7DsJoB * test(scope-resolution): assert every resolver refuses external imports (#2953) One property, for all 16 registered resolvers: a specifier naming something outside the repository must not resolve to a file inside it. That is the property #2953 was filed against, and its violation is not a missing edge but a fabricated one — an IMPORTS edge at full confidence between two files with no relationship, which `impact` then reports as blast radius. The mechanism is shared (`suffixResolve`), so the guard is too. Every case pairs an external specifier with a DECOY: an unrelated in-repo file whose path ends the way the specifier does. Without one a resolver that merely found nothing would pass while holding no property at all, so each case also asserts the decoy is reachable by the spelling that SHOULD find it — a typo in a fixture cannot manufacture a pass. Two fixtures had to be corrected before the results meant anything, and both would have recorded a false gap: - C# reads its #1881 gate from scanned namespace evidence and fails OPEN without any, so passing `undefined` measured nothing. Armed, C# holds. - C++ was posting a pass on an extension mismatch (`vector` could never match `src/vector.hpp` whatever the resolver did). Given the header spelling, it does not hold. Result: six hold it — TypeScript, JavaScript and Vue because they resolve against declared config only (#2953); Python (#898) and C# (#1881) because they gate the fallback on in-repo evidence; Rust because `::` never decomposes into a path suffix, which the decoy-reachability arm confirms is a real pass rather than a vacuous one. Ten do not, and are recorded in KNOWN_GAPS with what each currently answers: Java, Kotlin, Go, Ruby, PHP, Dart, Swift, C, C++, COBOL. The map is a work list, not an allowance — the entries are ASSERTED, so a language that starts holding the property fails here and its line gets deleted deliberately rather than rotting into a lie. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015Px638Zyqa9CJMUU7DsJoB * fix(typescript): admit only declared workspace packages, and fix four resolver defects (#2953) Review of #2956 found one boundary bug and four correctness defects. The boundary one is the same defect class this PR exists to fix, arriving from a different direction. ## The workspace boundary (review) `loadNodeWorkspacePackages` registered every `package.json` the repo-wide scan found, and never read `pnpm-workspace.yaml` or a root `workspaces` declaration. Finding a manifest is not the same as the workspace admitting one: an app importing registry package `foo` would bind to an excluded fixture or example that happens to declare `name: "foo"` — the false-positive half of #2953, from a new source of evidence. This repository is the example, since `test/fixtures/**` declares `@repo/utils` among others. The admitted set now comes from the declaration — `workspaces` (array and yarn object form), `pnpm-workspace.yaml`, `lerna.json`, with `!` exclusions and `*`/`**` — plus the root package itself. A repo that declares no workspace has exactly one package: the root. A negative fixture pins it, with a named package outside the declared globs that must not resolve. ## Four defects - tsconfig `paths` targets were resolved against the config's own directory when it declared `paths` but inherited `baseUrl`. tsc resolves them against the EFFECTIVE base, so an extending config loaded the right alias pattern and pointed every target at the wrong directory. - two configs in one directory were ranked by directory-listing order, so `tsconfig.base.json` could govern instead of `tsconfig.json` and a config's own `paths` went invisible. Found by the test written for the fix above. - an unexported package subpath also tried `<dir>/src/<subpath>`. Nothing declares that mapping; it is the same kind of guess this PR removes, and the import it "resolved" is broken in the real project too. - `imports` pattern keys (`"#internal/*"`) were looked up exactly, so a valid `#internal/foo` never matched. `exports` and `imports` now share one matcher, which is where they should never have diverged. - a relative specifier climbing past the repo root was silently clamped, so `../../../secret` from `src/main.ts` became `secret` and could resolve a root file it never named. ## Test rigor The conformance suite asserted less than it claimed. The decoy-reachability arm only checked non-empty, so five cases paired `reachesDecoy` with a different file than `decoy` and passed while establishing nothing; the KNOWN_GAPS arm likewise accepted any in-repo answer instead of the recorded one. Both now assert the exact file. The reachability arm runs only for languages that HOLD the property — for a gap language the recorded-answer assertion IS that proof, and for Swift and COBOL no other spelling exists, since `Foundation` and `EXTERNAL` name the in-repo directory and copybook as well as the external module, which is precisely why those resolvers cannot tell them apart. ## Benchmarks Both `--check` guards were red, and both were reporting something true. `import-target`: the ts-family arms resolved 0 of 3200 imports. Their corpus is bare specifiers with no config, which the deleted `suffixResolve` answered without one — so the arms measured an empty branch while printing a clean scaling ratio. Each now carries the config its corpus is spelled for, and the `deep` arm's uniform prefix reaches it. THE FINGERPRINTS THEN MATCHED THE RECORDED BASELINES EXACTLY: same corpus, same targets, once the config it always implied is passed explicitly. Retained per-pass index went from 26 745 296 B (js, ts) and 28 884 016 B (vue) at 32 000 files to 0-16 B, because these resolvers no longer build one; they move to the `HEAP_BOUNDED` tier rust already occupies for the same reason. Depth ratio moved 2.0 -> ~2.2 and the budget goes to 2.6: candidates now carry the 16-segment baseUrl prefix, so each `Set.has` hashes a longer string — linear in path LENGTH, independent of file COUNT. `scope-capture`: TypeScript capture fingerprint drift, caused by this PR's 12 new `.ts` fixtures entering the corpus. Attribution is exact rather than inferred — moving that one fixture directory aside returns the fingerprint to `f719163e…` byte-for-byte with `fixture_count` back at 155 and all 15 languages passing.

Four findings, judged against what this tool is: a static analyser building a code graph, not a compiler. The bar is resolving what the project DECLARES, on a checkout that may never have been built or installed, and never inventing an edge. - `exports` and `imports` ARRAYS were skipped. An array is Node's ordered fallback list, and `{"./feature": ["./dist/feature.js", "./src/feature.ts"]}` is exactly what a workspace package publishes to mean "built output, or source". Skipping it dropped the declaration entirely and left the package looking as though it exported no subpaths. The source arm is the one that matters here, because `dist/` is build output and is not indexed — and for a static analyser the build need not have run at all. - an exact `paths` pattern did not reliably outrank a wildcard. `a` and `a*` both match `a` with the same literal prefix length, so sorting on length alone left tsc's exact-wins rule to declaration order. - package-form `extends` (`"@acme/tsconfig"`) was refused outright. Not indexing `node_modules` is different from not READING it, and a shared internal base is where a monorepo puts the `paths` its packages import through. It is now read from disk, walking `node_modules` up from the extending config the way Node does, and absent on an un-installed checkout it degrades to whatever that config declared itself. The test pins what tsc actually does with such a base rather than what one might hope: `extends` never rebases `baseUrl`, so a package base's paths point at the package's own directory. That is why a published base rarely contributes aliases a repo's files resolve through, and why the `@tsconfig/*` family — which sets `target` and `lib`, never `paths` — is a no-op here either way. - CodeQL flagged `String.replace('*', …)` in two places as replacing only the first occurrence. Node subpath patterns and tsconfig `paths` both allow AT MOST one `*`, so that IS the specified behaviour — but the spelling states it by accident and reads as the replace-all footgun. `substituteStar` slices at the known index and says the rule.

Two findings, both valid, both cases of this resolver being laxer than the thing it models — which is the direction that fabricates edges. - `exports`, when a manifest declares it, is the package's ENTIRE public interface: Node ignores `main` outright and refuses any subpath the map does not list. This resolver already honoured that restriction for SUBPATHS and not for the package ROOT, which is the same rule. A manifest exporting only `"./feature"` therefore still answered a bare `@repo/pkg` with `main` or `src/index` — an edge for an import that does not resolve in the real project. Legacy and conventional root candidates are now offered only when there is no `exports` field at all. - a tsconfig declaring neither `baseUrl` nor `paths` was dropped rather than kept as an empty scope, so `tsconfigFor` fell through to an enclosing config. A package whose own tsconfig declares no `baseUrl` — meaning its non-relative specifiers are package lookups — silently inherited the repo root's aliases instead. An empty scope is the accurate answer for such a file, and only a scope can express it. Both are pinned at the level they broke: the manifest arms assert what `readManifest` produces, not a hand-built package, since the resolver honouring empty entries and the loader producing them are different claims.

Gergő Magyar	77360e1043	fix(scope-resolution): make interface dispatch generic-instantiation aware (#2912) (#2939) ... * fix(scope-resolution): make interface dispatch generic-instantiation aware (#2912) Interface-dispatch fan-out walked the subtype closure with generic arguments erased, so `IValidator<string>` and `IValidator<int>` — one declaration, one subtype list — were indistinguishable and a call through the first reached `IntValidator.Check(int)`, a target no runtime dispatch can produce. The arguments were already in the capture, unread: every language anchors `@reference.inherits` on the whole base node while `@reference.name` keeps the erased base. `ReferenceSite.typeArguments` is therefore derived generically in `scope-extractor.ts` from the anchor's own spelling — no per-language query changed — covering C#, Java, TypeScript, Kotlin, Go (`Base[int]` embedding), Python (`Base[User]`) and Swift; Rust and Dart anchor on the bare name and get nothing, which reads as "unknown". `preEmitInheritanceEdges` is the only code that pairs a heritage site with a resolved (subtype, supertype), so it records the instantiation there and hands it to the dispatch pass. The closure is then walked carrying a substitution, as a type checker would: `Wrapper<T> : IValidator<T>` binds T to the receiver's argument and stays reachable from every instantiation, while its own subtypes are matched against that binding. An incompatible hop is skipped without being marked seen, so a type reachable by a second, compatible path still gets its edge, and without descending, since its subtypes inherit the mismatch. Pruning happens only on positive evidence that two instantiations differ. Unknown arguments on either side, an arity that does not line up, an unresolved qualified spelling of the same simple name, or an argument that might be a type variable the language never captured all keep the target. Telling an uncaptured type VARIABLE from a concrete type is the crux: `typeParameters` is absent both for a non-generic declaration and for every declaration in a language whose query omits `@declaration.type-parameters`, so the pass reads the evidence in front of it — one run resolves one language, so a single generic declaration anywhere in it proves the captures record parameters. A language recording neither arguments nor parameters keeps exactly its pre-#2912 fan-out. Type arguments are compared as resolved declarations rather than spellings, so `Models.User` and an imported `User` are one type; the new optional `ScopeResolver.normalizeTypeArgument` hook canonicalizes a language's predefined aliases, implemented for C# (`string` ≡ `String`) where mixing the spellings would otherwise delete a real implementor. Fan-out cap, skipped-target reporting, overload selection and non-generic closure behaviour are unchanged. SCHEMA_BUMP 60 -> 64: the heritage arguments are a parse-time capture, so a warm cache would replay pre-fix sites and leave the filter silently inert on unchanged files (61/62/63 are claimed by open PRs). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01StNKYi7Qxv5DnSURZuFBef * fix(scope-resolution): close the two generic-dispatch gaps (#2912) The first commit left two shapes on the pre-#2912 fan-out. Both are now covered, and the second one turned out to need a route the pipeline did not have at all. **Folded receivers (Cases 0 and 3b).** `this._validator.Check(x)` is typed by the compound fold, and the fold answers with a CLASS — which is exactly what loses the instantiation, since `IValidator<string>` and `IValidator<int>` fold to one declaration. The fold now reports the SPELLING it typed each receiver position from, through a pure side channel (`recordReceiverType`) added to the one helper every declared-type route already shares plus the two return-type routes; resolution is unchanged whether or not a caller passes it. The reader keeps the last report and uses it only when it names the class the fold returned, so an intermediate position cannot lend its arguments to another class. This covers the dependency-injection shape the issue is really about — a field-held generic interface — and multi-hop chains, where it is the last hop's spelling that types the receiver. **Rust and Dart heritage.** Neither recorded arguments, for two different reasons, so both routes exist now: - Rust's `@reference.inherits` anchor is the trait identifier INSIDE a `generic_type`. Widening the anchor would move the site's range, and that range is part of every inheritance edge's id, so the arguments arrive through a new `@reference.type-arguments` sub-tag instead. - Dart's `implements` / `with` never become reference sites at all: they travel as heritage MARKERS and their edges are emitted by the language hook. The arguments ride the marker payload as an optional fourth field (dropped, not encoded, when the spelling contains the marker delimiter), and `ScopeResolver.emitHeritageEdges` now receives the same sink `preEmitInheritanceEdges` writes to, so whichever pass emits an edge records that edge's instantiation. Dart also gained the `@declaration.type-parameters` capture, without which its own type VARIABLES are indistinguishable from concrete arguments and `class Box<T> implements Validator<T>` would be pruned from every instantiation. Note this makes Rust and Dart record their instantiations; it does not make them fan out. Interface dispatch still fires only for a receiver whose folded type is an `Interface` symbol, so a Rust `Trait` or a Dart abstract `Class` receiver has no secondary targets to filter. Widening that gate emits new edges for several languages and belongs to its own issue. **Two matcher rules the wider coverage exposed.** A WILDCARD names a set of types rather than one — `Repo<? extends User>` holds a `Repo<User>`, and Kotlin's `Repo<*>` / `Repo<out User>` say the same — so a position with one on either side is unknown; nullable spellings trip the same test, which costs a little precision in the safe direction. And insignificant whitespace inside a nested spelling (`Map<string, User>` vs `Map<string,User>`) is no longer a difference. One expectation changed in the #2833 field-receiver matrix: a `Repo<Repo<User>>` receiver no longer reaches `UserRepo implements Repo<User>`. That edge is precisely the false positive this issue is about, and the primary edge to the interface's own declaration — which is what the matrix row exists to prove — is untouched.

Both now call `balancedTailList`; the rule that rejects `User[][]` and `Repo<User>?` lives in one place instead of being free to drift between two. **The receiver's arguments are parsed after the gates, not before them.** `emitInterfaceDispatchFor` takes the receiver's declared SPELLING and parses it itself, once the owner is known to be an Interface with subtypes. Every one of the five cases calls it unconditionally and the overwhelming majority of receivers are concrete classes that return at the first line, so the parse was running per resolved receiver site to be discarded immediately. Case 4 and Case 6 now hand over the string they already hold, and the folded-receiver helper returns the recorded spelling rather than parsing it. **One question gates the whole instantiation apparatus.** Inside the closure walk, the graph-id lookups now hang off "is the supertype's instantiation known?" — false for every non-generic receiver and for every language that captures no heritage arguments, which is what makes those walks cost exactly what they cost before #2912. Also lifted the argument-route choice in `pass5CollectReferences` out of a nested ternary into a named `heritageTypeArguments`, where the reason the explicit sub-tag wins over the anchor text can be stated once.

No production code changes — the derivation is language-agnostic by construction (`heritageTypeArguments` reads the heritage anchor's own spelling), so the question was only which languages actually reach the filter. Kotlin rides the shared heritage pre-pass; Go reaches the same filter from the other side, matching implementors structurally while the receiver's `Validator[string]` spelling carries the instantiation. Both are confirmed to prune the mismatched implementor. Each language gets a NON-GENERIC control asserting the fan-out still reaches every implementor. Without it the `not.toContain` assertion passes just as well when a language emits no dispatch edge at all — which is what Dart, Python and Rust were measured doing for this receiver shape, generic or not. They are deliberately not asserted on here: a "filtered correctly" test over a path that never fans out measures nothing.

The baselines were never re-measured when those captures landed, which left `measure.mjs --check` red on this branch independently of the merge. Re-measured rather than hand-edited. Rust's capture_groups_fp (3556) and fixture_count (202) are unchanged across the move, which is the evidence that this is digest drift and not a capture-set regression. The other 13 languages are byte-identical; 15/15 pass.

Findings from a four-angle review (reuse, simplification, efficiency, altitude), applied where they were verified. Reuse / duplication: * `stripTrailingCallSuffix` was a second copy of `matchingOpenParen`'s backward balanced-paren scan. Both now live in `template-arguments.ts` beside `balancedTailList`, for the reason that helper was shared in the first place: two copies of a scan this fiddly are free to disagree. * The two call-return arms of the compound fold repeated the same four-part expression character for character; they share `classOfReturnType` now, the return-type twin of `classOfDeclaredType`, which keeps the "look up by rawName, report the erased application" pairing in one place. * `pipeline/run.ts` implemented first-writer-wins twice — once in the pre-pass and once in the provider sink. One store, one sink, one rule; the pass keeps its `Set<string>` return and the callable-flow-only arm stops building an empty map to satisfy a widened return shape. Simplification: * `subtypeParametersComplete` dropped a disjunct that could never decide: every `subDef` reaching it comes out of the same loop that sets `languageCapturesTypeParameters`, from exactly those defs. * The heritage-argument lookup asked "is the supertype's instantiation known?" three times; `superGraphId` now gates the block once. * `TypeArgumentResolver` and `HeritageInstantiationResult` un-exported — no consumer outside their module. Efficiency (all on the per-site dispatch walk): * `resolveSupertypeArgument` captures only the site, so it is built once per site instead of once per subtype visited; the subtype's scope id is looked up once per subtype instead of once per argument position. * `erasedTypeApplication` no longer runs on every fold hop through a call — the spelling is built only once the lookup has found a class, since it is discarded otherwise. * `normalize`+`compact` computed once per side rather than twice. * Regex literals and the identity `normalize` fallback hoisted to module scope. * C# `System.` prefix stripped with `startsWith`/`slice` instead of a regex. Verified: tsc clean, build clean, 1994 scope-resolution unit tests, 171 generic-dispatch + generic-field-receiver integration tests, 15/15 capture bench fingerprints unchanged.

A repeated type variable was rebound rather than unified: `class C<T> : Pair<T, T>` accepted a `Pair<string, int>` receiver, with `T = int` silently replacing `T = string` and the bogus substitution carried to the next hop. It now unifies, and prunes only on the same positive evidence the concrete path demands — an undecidable repeat keeps the target with no binding. A type PARAMETER of the declaration enclosing either side is now recognised and never compared. `subtypeParametersComplete` is evidence about the SUBTYPE's parameter list and says nothing about a `T` written at the call site, so `void Run<T>(IValidator<T> v) { v.Check(x); }` pruned every implementor: unbounded, `T` grounds to nothing; bounded, it grounds to its BOUND. Both read as a difference of type. That is the missing-edge failure this filter is built to avoid, and it is the common dependency-injection shape in C#, Java and Kotlin. Making that recognition reliable is why generic METHODS now capture `@declaration.type-parameters` in C#, Java and Kotlin — TypeScript already did, which is why its generic functions never had the defect. The capture feeds the existing `bindsTypeParameter` guard, so a method-level `T` also stops resolving to a same-named class in every other lookup. C# alias normalization additionally strips the `global::` qualifier, which `import-decomposer` already unwraps elsewhere: `global::System.String` read as unequal to `string` and pruned a live implementor. The C# captures golden fixture is regenerated for the new capture; the extractor reads `@declaration.type-parameters` generically, so no reader changed. SCHEMA_BUMP 64 already covers these capture changes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015Px638Zyqa9CJMUU7DsJoB * fix(scope-resolution): close the two remaining gitnexus-check findings (#2912) `balancedTailList` counted ONE bracket family, so a crossed pair slipped through: scanning `Foo<Bar]>` it never sees the `]`, reaches the final `>` at depth zero, and reports `Bar]` as a balanced argument list — which `typeApplicationArguments` then splits and `erasedTypeApplication` rebuilds a spelling from. It now tracks a stack of expected closers, so every closer must match the opener it actually closes and a crossed pair declines to `undefined`, the "unknown" both callers already fail open on. Well-formed mixed nesting (`List<Dict[a, b]>`) is unaffected. C# `normalizeTypeArgument` stripped `System.` from every qualified spelling, so `System.Custom` answered `Custom` and compared equal to an unrelated `Custom` elsewhere in the workspace. The strip is now earned: a keyword answers from the alias table first, and the qualifier is dropped only when what remains IS a predefined type. `System.Custom` is returned as written and goes to the identity comparison instead — the step that can actually tell two declarations apart. `global::System.String` still meets `string`. Both are pinned by unit tests, including the well-formed mixed nesting and the `global::`-qualified ordinary type that must keep its qualifier. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015Px638Zyqa9CJMUU7DsJoB * docs(csharp): record why a shadowed `String` keeps its implementor (#2912) Answers a review finding rather than changing behavior. A workspace may declare its own type named `String`, shadowing the BCL simple name, and the alias table then reads `IValidator<String>` as the `string` instantiation and keeps that implementor. That is the SAFE direction, not an oversight: pruning instead would rest on the belief that two spellings differ, which is the missing-edge failure `generic-instantiation.ts` exists to avoid. Resolving rather than normalizing cannot settle it either — the identity comparison needs a `definitionId` from both sides, and a built-in name carries none, so "built-in versus workspace-declared implies different" would be a new prune with no positive evidence behind it. The cost is one surplus edge for that pair, which is exactly the pre-#2912 fan-out and no worse. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015Px638Zyqa9CJMUU7DsJoB * refactor(scope-resolution): pair the receiver spelling with the class structurally (#2912) The fan-out needs the spelling a receiver position was typed from, because the class the fold returns has lost the generic arguments. That was carried by a PASS-LEVEL mutable holder, written by every declared-type lookup anywhere in the fold and read back through a def-id coincidence check, with the holder cleared by hand before each call site. Three things were load-bearing and none were enforced: * the reset had to be remembered at every call site. It was not: the Case 3b retry (`rawName` then `rawName + '()'`) reset once, BEFORE the first attempt, so a spelling reported by the attempt that failed could be attributed to the one that succeeded. * the holder outlived every resolution, so a site that resolved through a route reporting nothing could read the previous site's spelling if the def ids happened to line up. * the pairing itself was inferred from "whichever lookup reported last", not from the fold's own bookkeeping — losing branches (an MRO walk that moved on, a step later folded past) report too. `foldReceiverChain` already had the answer and threw it away: its final `FoldState` holds `def` and `declaredType` produced by the SAME step. It now reports that pairing last, so the structural route is the one that stands. `resolveCompoundReceiverTyped` returns `{def, declaredSpelling}` and owns a sink created and read within the single call, which is what removes the reset discipline — a local cannot be forgotten, and each of the two retry attempts carries its own. The def-id guard stays as the check that a report names the class actually returned. Behavior is unchanged: 1975 scope-resolution unit tests, 177 generic-dispatch and generic-field-receiver integration tests.

Gergő Magyar	135bcae03d	fix(go): resolve out-of-repo package qualifiers, and stop reporting an undecided interface check as a decided negative (#2873) (#2921)	2026-08-11 10:36:59 +01:00
Carter LaSalle	81100e2c74	fix(python): resolve calls through __init__.py re-exports (#2864) ... * fix(python): resolve calls through `__init__.py` re-exports A call to a name imported from a package never resolved when the package's `__init__.py` re-exported it rather than defining it: pkg/impl.py def target_fn(x): ... pkg/__init__.py from pkg.impl import target_fn caller.py from pkg import target_fn def calls_it(): return target_fn(21) # no CALLS edge `caller.py` gets no CALLS edge. Both IMPORTS hops are recorded, and all four functions are extracted as nodes — only the call binding is missing. Because `__init__.py` re-exports are how Python packages declare a public surface, this misses a large fraction of real call edges, and the failure is silent: the defining file looks like dead code with zero callers. The re-export closure that should carry this already exists and is fully general (`buildReexportClosures` — SCC over the re-export subgraph, bounded fixpoint for cycles, transitive `via` chains). Python just never fed it: the subgraph admits only `kind: 'reexport'` and `kind: 'wildcard'`, and Python emits neither for `from m import x`. Python has no dedicated re-export form. A module-level `from pkg.impl import X` binds X locally AND publishes it as `pkg.X`, so it is both a named import and a re-export. Emitting `kind: 'reexport'` would be wrong — that form drops the local binding, which Python's does create. Instead add an optional `reexportsName` flag to the `named`/`alias` variants, alongside the existing provider-specific `importedSymbolKind` / `targetIncludesImportedName` flags, and admit flagged imports into the closure subgraph. Languages with an explicit form keep emitting `kind: 'reexport'` and leave the flag unset, so nothing changes for them — a negative-control test asserts a plain named import still does not resolve. Verified on a fixture covering the three shapes (direct, top-level-via-re-export, function-local-via-re-export): 1 of 3 CALLS edges resolved before, 3 of 3 after. On a 12.4k-file Python/Go/TypeScript repository: edges 294,416 -> 301,443 (+7,027) and execution flows 300 -> 813. A previously "100% orphaned" module (`shared/db/event_writer.py`) now correctly reports its caller. 5 new finalize tests (single hop, 3-hop chain, alias keying, cycle termination, and the negative control) plus 6 updated Python fixture shapes. `npx tsc --noEmit` clean in both packages; full unit suite shows no regression against baseline (remaining failures are pre-existing load-sensitive flakes in analyzer-identity / evidence-provenance-helper / skip-git-cli / hooks, each verified passing in isolation). * fix(python): set reexportsName only for module-level imports `interpretPythonImport` flagged every `from m import x` as republishing the name, but only a module-level statement does. A `from m import X` inside a `def` or `class` body binds locally and puts nothing in the module namespace, so flagging it fabricates a re-export of a name no importer can reach: # pkg/__init__.py def loader(): from pkg.impl import InternalHelper # caller.py from pkg import InternalHelper # CPython: ImportError resolved to `def:pkg.impl.InternalHelper`. Worse, with declaration-order first-wins in the closure, a scope-blind entry could claim a name ahead of the real module-level import and give a WRONG def for legal, running code. `interpretImport` receives a `CaptureMatch`, which is `{name, range, text}` with no syntax node, so the scope is not recoverable there — and it is not recoverable downstream either: `pass3CollectImports` applies no scope filter and `ImportEdgeDraft.fromScope` is hardcoded to the module scope. The decision therefore moves up to `import-decomposer.ts`, which still holds the live `import_from_statement` node, and rides down as an `@import.publishes` marker. Computed once per statement, not once per imported name, with the existing `findAncestorBeforeBoundary` helper. Only `function_definition` and `class_definition` suppress publication. `if` / `try` / `for` / `with` do NOT — Python has no block scope — so the predicate is an ancestor walk for those two node types and nothing else. Verified against CPython 3.11 in both directions; both are now pinned by tests, including the counterpart control that a branch-nested import still republishes. Also corrects the docblock in `scope-extractor.ts` that sent this change the wrong way. It claims pass 3 attaches imports "not to any `Scope` — finalize reconstructs the owning scope via `provider.importOwningScope` during Phase 2". Finalize does no such thing: `importOwningScope` is declared on `LanguageProvider` and implemented by a dozen providers, and `grep -rnE "\.importOwningScope\b" gitnexus/src/` returns exactly one hit — that doc comment. Nothing invokes it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Rzsb6mdGtbu66BG1EaF6Zz * fix(shared): stop guessing ambiguous and namespace re-exports; bound the via chain Four changes to the re-export closure, all reachable only now that Python feeds it. 1. AMBIGUOUS NAMES ARE DROPPED, NOT GUESSED. `populateFileClosure` documented "declaration order first-wins for duplicates of the same exported name", which is sound only where a duplicate export is illegal — two `export { X } from …` is a TypeScript compile error, so the rule never fires. Python has no such guarantee: from .v1 import Client # legacy, left behind from .v2 import Client # the actual public Client CPython binds v2 (verified on 3.11); first-wins attributed every `from pkg import Client` in the repo to the DEAD implementation, and `impact("Client")` pointed at the wrong file. Last-wins is not the fix either: for the equally common `try:`/`except ImportError:` and `if sys.version_info` pairs exactly one branch runs, and which one is not decidable here. Both directions are wrong on real code, so the entry is dropped — the importer stays unresolved, which is exactly the pre-#2864 answer, and the file-level IMPORTS edge is untouched. `collectAmbiguousReexports` runs as a PRE-PASS over data phase 0 froze, so the poisoned set is constant across the fixpoint. That matters: a set that grew mid-fixpoint would need retraction to propagate to files that already inherited the name, would make `myClosure.size > before` an unsound progress signal, and would invalidate the `|SCC| + 1` cap. As a pre-pass the closure map stays monotone and every existing termination argument survives unchanged. Only two flagged drafts resolving to two DIFFERENT in-workspace files count; duplicates of one target are harmless, and unresolvable targets never entered the closure. Checked in both loops. Named re-exports take precedence over wildcards, so suppressing only the named loop would hand the name to a later `import *` and reinstate an arbitrary winner through the back door. 2. NAMESPACE-RECLASSIFIED DRAFTS ARE EXCLUDED. The admission guards tested `draft.source.kind` while `tryFinalize` tests the post-reclassification `draft.base.kind`. Python's `from . import logger` is emitted as `named`, reclassified to `namespace` by `isNamespaceImport`, and was still admitted — republishing whatever def shared the module's simple name. For a `logger.py` holding a module-level `logger = logging.getLogger(...)`, importers of `from pkg import logger` bound to that Variable instead of the module. Reproduced end to end. Both predicates now take the draft and test `base.kind`; this is a no-op for TS/Rust, whose only `isNamespaceImport` implementation is Python's. 3. `transitiveVia` IS CAPPED AT 32. Each hop copies the inherited path, so an unbounded chain is Theta(depth^2) in time AND retained memory, and Theta(|SCC|^2) for a cycle whose chain tracks it. `MAX_REEXPORT_DEPTH = 100` covered this until fc919ad6 removed it — correct for the shallow TypeScript barrels that were then the only input, and invisible until the input class changed. Measured at depth 400: 67 ms / 145 MB uncapped vs 25 ms / 40 MB capped. 32 against a real-world worst case of ~6 for `__init__.py` chains. Safe because `ImportEdge.transitiveVia` has no production reader — it is diagnostic provenance, emitted and typed but dropped by graph emission. 4. `localDefs` ARE INDEXED BY SIMPLE NAME. `findExportByName` linearly scanned a target's defs on every call, and the phase-3 fixpoint rescans the same target once per iteration. Memoized on the array identity, which `FinalizeFile` documents as static input. Worth 12-14% where lookups repeat and neutral elsewhere. The 46-line algorithm docblock was also ORPHANED by the helpers inserted between it and `buildReexportClosures` — AST-verified, that function had zero jsdoc blocks, so the cross-reference elsewhere in the file landed on an undocumented function. Helpers move below it (declarations hoist), and its step 1, precedence and complexity sections are rewritten: they still claimed regular imports do not contribute to the export surface, and justified the via-copy cost by TypeScript barrels being shallow. The `reexportsName` contract consolidates onto `ParsedImport`, where its "`kind: 'reexport'` would drop the local binding" rationale is corrected — `materializeBindings` creates a module-scope binding for every linked edge, re-export included. The real reasons are that `origin` flips, changing evidence weight and priority, and that it misreports Python's syntax. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Rzsb6mdGtbu66BG1EaF6Zz * test(shared): add a re-export closure scaling guard to CI No bench covered `buildReexportClosures` at all. Until #2864 its input was TypeScript barrel files — a handful of shallow edges — and it admitted only `reexport` and `wildcard` drafts. It now admits every module-level Python `from m import x`, measured ~20x more edges on the CPython stdlib and cyclic SCCs where there were none. The pass went from "rarely runs" to "runs over the whole named import graph" with nothing watching it. The regression this guards has already happened once: fc919ad6 removed `MAX_REEXPORT_DEPTH`, which was correct for shallow barrels and stayed invisible for as long as the input stayed shallow. The depth arm is an EXACT structural assertion — build a chain far past the cap, assert the longest emitted `transitiveVia` is exactly `MAX_VIA_LENGTH`. It started as a `depth_ratio` timing arm and that was a bad gate: sampled five times capped it scored 2.71-3.52 and three times uncapped 5.87-7.65, so the ranges nearly touch and one uncapped run came in UNDER budget. A gate that passes a third of the time on a broken build is worse than none, because it gets read as evidence. The structural form fails 3/3 with 401 vs 32. `width_ms` stays a timing arm with a deliberately loose budget, because a structural check cannot see a constant factor: restoring a per-lookup linear scan of `localDefs` leaves every array length untouched while making every real analyze slower. Both arms drive `finalize` through INDEXED hooks. Reusing the unit tests' `defaultHooks` is the trap — its `resolveImportTarget` does `files.some(...)` per import, which is O(imports x files) in the FIXTURE and swamps the pass so completely that removing the cap measures as no change at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Rzsb6mdGtbu66BG1EaF6Zz * fix(cache): bump SCHEMA_BUMP 53 -> 60 for ParsedImport.reexportsName `reexportsName` is a new field on `ParsedImport`, and `parsedfile-store.ts` serializes the whole `ParsedFile` generically — so it is part of the cached shape even though it is not a capture, which is the easy-to-miss variant of the rule `parse-cache.ts` states as a MUST. (The `@import.publishes` marker added alongside it moves the capture output too, so this qualifies twice; the python captures golden confirms the drift.) Without the bump, a warm `parsedfile-cache` replays pre-fix `ParsedImport`s carrying no flag, `isNamedReexport`'s strict `=== true` takes the old path, and the entire fix is a SILENT NO-OP on incremental analyze while every cold-run test passes. It lands hardest on `__init__.py` — the rarest-changing, highest-cache-hit files in a Python repo, i.e. exactly the target. A published npm release invalidates via `GITNEXUS_PKG_VERSION`; dev trees, main-HEAD installs and CI with a restored cache dir do not. 60, not 54, because the value has to clear every in-flight claim rather than just origin/main: main is at 53 while open PR #2899 claims 54 and #2891 claims 59. Five exact clashes are recorded in the ledger, and the pin test cannot detect a tie — both sides assert the same number and both pass. RE-CHECK against origin/main immediately before merging. Also documents the divergence between `pythonFileExportsName` and the re-export closure. That predicate answers "does this package expose X?" from `localDefs` alone, so with `pkg/__init__.py: from .impl import log`, `pkg/impl.py: def log` and a same-named `pkg/log.py`, `from pkg import log` still targets the submodule and the closure is never consulted — for exactly the case it was built for. Deliberately NOT fixed by reusing the flag, which is the obvious three-line change and is WRONG: `reexportsName` is also set for `from . import log`, where CPython binds `pkg.log` to the MODULE, not a name (verified on 3.11 against the `from .impl import log` form, which binds the function). Returning true there would kill the correct namespace edge. Separating the two needs the re-export's own resolved target — i.e. re-entering `resolvePythonImportTarget` from a different `fromFile` — and that classification is the subject of open issue #2882, so it belongs with that fix. Not a regression: both halves behave exactly as they did before #2864. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Rzsb6mdGtbu66BG1EaF6Zz * test(python): re-baseline the scope-capture fingerprint for @import.publishes CI's `bench/python-scope/measure.mjs --check` failed on capture fingerprint drift. Intentional: the module-level marker added for `reexportsName` is a new synthetic capture, and that guard hashes `tag|text|range` over every `emitPythonScopeCaptures` output. Attributed before re-baselining rather than after. Reverting ONLY the `@import.publishes` emission — nothing else — restores the previous hash a0da3e7c exactly, so the whole drift is that one marker. `capture_groups_fp` is 3246 either way and `scaling_ratio` stays ~1.0, so no capture group appeared or vanished and the pass is still linear. The other nine bench guards were run rather than assumed: scope-capture, callable-value-flow, finalize-reexport, cpp-qualified-ns, kotlin-import-target, receiver-resolution, scope-emission, import-target and cfg all pass. The benchmarks job runs under `-e`, so this failure masked whatever followed it — worth checking the rest before pushing a one-line baseline change.

DuduPhudu	fa31a7d824	fix: close the nine follow-up review findings from #2856 (routes, receiver typing, truncation honesty) (#2899) ... * fix(typescript): a type parameter shadows a declared type of the same name (W2-8) First item of wave 2, promised to the reviewer on #2856. `export function unwrap<Result>(value: Result): Result` names the PARAMETER, not the `interface Result` beside it — tsc resolves both annotations to the parameter. The type-reference capture that makes a contract answerable ("what breaks if I remove this field?") had no notion of a parameter binding, so every annotation mentioning `Result` inside `unwrap` minted a `USES` edge into the interface, at the same confidence as a real consumer and indistinguishable from one. Measured on the new fixture: `unwrap` produced TWO false edges while the genuine consumer produced one. Blast radius is every generic whose parameter name collides with a declared type, and the colliding names are ordinary choices for both: `Result`, `Key`, `Value`, `Item`, `Node`, `Options`, `Config`, `Props`, `State`, `Response`. TWO HALVES, and the first is why upstream's fix could not reach this. #2833 introduced `bindsTypeParameter` for the CALL-receiver path, where a workspace `class T` was answering for `<T>`. Reusing it here changed nothing at first, and the reason is its own documented contract: `@declaration.type-parameters` was captured for class/interface declarations ONLY, so a generic FUNCTION recorded no parameter list and the predicate correctly returned false — absence is not evidence. The data was missing, not the logic. So: - TYPESCRIPT_SCOPE_QUERY now captures type parameters on `function_declaration`, `generator_function_declaration` and `type_alias_declaration`; - the graph bridge consults `bindsTypeParameter` before emitting `USES`. Both are load-bearing — removing either one fails the fixture. The fixture carries two controls, because the obvious wrong fix is to stop emitting: a genuine consumer of the interface must still link, and a generic whose parameter does NOT collide must still link its real reference. Both are asserted, and the "genuine consumer" case is asserted FIRST so the absences below it cannot pass vacuously. SCHEMA_BUMP 53 -> 54: parse-time capture change. A warm cache replays defs with no parameter list, so the guard reads nothing and the feature is inert while looking implemented. Capture fingerprint re-baselined with justification. NO NEW CAPTURE NAME — diffing the capture-name sets against the wave-1 branch returns empty; the tag existed and now fires on more declarations. capture_groups_fp 2338 -> 2371, fixture_count 151 -> 152, scaling 1.06 < 1.5, and JavaScript's fingerprint does not move at all, which is the check that this is the TS declaration rules rather than something broader. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(analyze): close the four false-success paths in the graph-write-collapse guard (W2-6) Second wave-2 item, promised on #2856. All four were reported; all four reproduced by reading the code they name. (a) A SAME-COMMIT RE-RUN REPORTED SUCCESS FOREVER. Every other meta-driven trigger — schema fingerprint, PDG mode, runner identity, CJK segmentation, embedding dims — has a block that forces a rebuild before the `alreadyUpToDate` fast path. `graphWriteCollapsed` had none; `grep -rn` found writes and no reads. So the one state meaning "most of your edges are gone" was the one state that repaired itself only if the user happened to pass `--force`. Now forces a full rebuild, and forcing is right rather than merely re-running: the persisted graph disagrees with what the pipeline produced, so an incremental pass over unchanged files would write nothing and re-stamp the same broken index as fresh. (b) AN INCREMENTAL RE-RUN ERASED THE STAMP. `saveMeta` is a full atomic overwrite, and the field was spread in only when the CURRENT run had a verdict. `undefined` meant two different things at that site — "full run, no collapse" (a positive all-clear) and "incremental write, not comparable" (no opinion) — so the second case silently dropped `graph-write-collapsed` from meta.json while the edges were still missing. Now three-way: stamp on detection, CLEAR on a healthy full run, CARRY FORWARD when there is no verdict. That is the shape `branch: branchLabel ?? existingMeta?.branch` two lines away had all along. (c) THE SERVER PATH NEVER CONSUMED IT. `analyze-worker-ipc.ts` projects the field "so a server-side caller sees the same degraded outcome the CLI does" — but nothing read it, so the comment described an intention and every collapsed run reported `complete` to the UI and to every API consumer. Now reports `failed` with the counts and the remedy, matching the CLI, which prints `Repository indexed INCOMPLETELY` and exits non-zero. A consumer that reads "complete" will query the index and get confident wrong answers. (d) --pdg ROWS MASKED TOTAL STRUCTURAL LOSS. `expected` counts the in-memory graph plus the streamed STRUCTURAL manifest; the streamed PDG layers never enter `graph.relationshipCount`. But `persisted` was `stats.edges`, a count of EVERY `CodeRelation` row, and PDG writes into that same table. With 1,000 structural edges expected and 4,000 PDG rows persisted, losing every structural edge still read `persisted = 4000`, cleared the ratio, and stayed silent — on exactly the large repos `--pdg` is used for. Worth recording that the OBVIOUS fix does not work. Padding `expected` with the PDG rows makes the two universes match but leaves the ratio judging a minority population: 4,000 of 5,000 still clears 0.5. I wrote that first, and the test I wrote to prove it failed. Only comparing structural against structural asks the question the check exists to ask, so `getLbugStats` gains a `structuralEdges` count excluding `PDG_EDGE_TYPES`. `TAINT_PATH` is deliberately NOT in that set — it is a whole-program Function→Function edge persisted by the normal emit, so it is structural and stays counted on both sides. `index-freshness-graph-collapse.test.ts` had pinned the masking as correct (`detectGraphWriteCollapse(1000, 4000)` → undefined, "PDG layers write into the same table, so persisted > expected is normal"). True about the table, and it licensed the hole. Replaced with the case that matters and a note on why the fix is at the caller. The new `structuralEdges` assertion in `lbug-core-adapter` is there because the failure mode is silent: the query sits in a try/catch that yields `undefined`, and `undefined` makes the collapse check decline to compare — so a typo in the Cypher would throw nothing, fail nothing, and switch the guard off. Verified against a real LadybugDB and mutation-checked by breaking the query. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(processes): make process selection insertion-order invariant (W2-5) Third wave-2 item. Reproduced before fixing: two equal three-step flows with `maxProcesses: 1` select `handleAlpha`; inserting the identical nodes and CALLS edges in reverse select `handleBeta`. Same repository, same commit, a different persisted graph — so a filesystem that enumerates differently, or an incremental run that reorders assembly, silently changes what the tool reports. Four sorts ranked by score or length alone and returned 0 on a tie. `Array.prototype.sort` is stable, so a 0 preserves INPUT order, which traces back to `graph.iterNodes()`. Under `maxProcesses` capping that decided which `Process` and `STEP_IN_PROCESS` nodes were persisted at all. Each now falls through to a totally-ordered, content-derived key — node id for entry points, the joined path for traces. WHAT IS ACTUALLY VERIFIED, stated precisely because "four fixes" would overclaim: - the ENTRY-POINT sort is individually mutation-verified; - the two DEDUP sorts are collectively mutation-verified; - the TRACE-RANK tiebreak is NOT individually observable, and the source says so. The dedup sorts already impose a total order on the list that reaches it, so removing it alone fails nothing. Kept as defence in depth: it cannot misbehave — it only makes an already-deterministic order explicit — and it is what stops a change to dedup ordering from silently re-opening this. Finding that out took two fixtures. The first (three chains, three entry points) is separated by the entry-point sort before trace ranking is reached, so it never exercises the trace comparator at all; the second gives ONE entry point two equal-length branches to different terminals, which is the only shape where the trace comparator decides. Both are kept — they gate different sites. The invariance tests assert the INVARIANT rather than any single sort, so they cover all four sites and any future one without needing to know where they are. Three assertions: same selection under a cap, identical set uncapped, and identical ORDER — the last because order is what the cap consumes, so a set-only assertion would pass while the defect persisted. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(impact): UNKNOWN dominates a mixed candidate set, instead of reporting the known floor (W2-4) Fourth wave-2 item. The all-UNKNOWN branch here was reasoned about carefully and is correct — its comment even names the two ways a set can be all-UNKNOWN. The MIXED case fell straight through it. `RISK_ORDER` is `['LOW','MEDIUM','HIGH','CRITICAL']` and has no `UNKNOWN` entry, so `indexOf('UNKNOWN')` is -1 and an UNKNOWN candidate can never win the reduce. An ambiguous name with one caller-less candidate (UNKNOWN, per the round-1 fix) beside one single-caller candidate (LOW) reported `maxRisk: 'LOW'` — a confident floor over a set containing an interpretation nobody measured. That is the same false-safe the all-UNKNOWN branch exists to prevent, one case over, and it surfaced in the UI as "Max blast radius N (LOW risk)". `maxRisk` answers "how bad could this be?", and an unresolved candidate could be CRITICAL — so any UNKNOWN in the set makes the aggregate UNKNOWN. Narrowing it that way would normally cost information, so the measured part travels alongside as `knownMaxRisk`, present only when the two differ: absent on a fully-resolved set, where it would duplicate `maxRisk`, and absent on a fully-unknown one, where there is no measured part. A reader gets "at least LOW among what resolved, and one interpretation could not be walked at all", which is strictly more than either value alone. The human-readable message says the same thing. The seed gained a mixed pair because the existing one could not reach this: both its twins are caller-less, so it only ever exercises the all-UNKNOWN branch — which is precisely why the gap survived a round of review. Three assertions, both halves mutation-verified. `eval-server.ts` needs no change: it renders `result.maxRisk ?? 'UNKNOWN'`, so it now shows UNKNOWN where it previously showed the floor. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(routes): track ternary polarity in dispatch guards, so a selected verb cannot be inverted (W2-9) `if ((req.method === 'GET' ? false : true) && pathname === '/api/i')` emitted `GET /api/i` — the one method that branch guarantees the request does NOT have. A ternary SELECTS between its arms, so a verb inside one is not reached merely because the whole condition is truthy, but `findVerbInSubtree` descended into both arms and returned the first verb it saw. Same inversion `!` produced before d4dcba8c, one level up. Handled by folding the ternary where an arm is a boolean literal, which is what collapses the selection into a conjunction: c ? A : false == c && A both hold, so search both c ? false : B == !c && B c must NOT hold, so search it at flipped parity c ? true : B == c || B a disjunction guarantees neither operand c ? A : true == !c || A likewise Two non-literal arms leave the verb chosen by an unknown condition, so the ternary guarantees nothing. Refusing every ternary would also have fixed the reported bug, but three of the four shapes measured were ALREADY correct and would have silently lost their verb; they are pinned now. A second defect in the same walk, found while reproducing: the `!` rule was keyed on PRESENCE, returning null at the first negation it saw, while `isNegatedContext` two functions above states the rule is PARITY and says so outright — `!!x` is `x`. So `!!(req.method === 'GET')` dropped a verb the source states plainly. The existing double-negation test covered the PATH position, where the parity walk already ran, and so never saw it. The verb walk now tracks parity too, and the two agree. Verb-less, not route-less: the path comparison is untouched evidence that the branch serves that path, so an inverted verb becomes a missing verb rather than a missing route. SCHEMA_BUMP 54 -> 55. Routes are emitted at parse time and replayed verbatim from a warm cache, so without the bump an already-indexed repo keeps serving the inverted verb and the fix looks inert. Free against origin/main (48). Every rule mutation-checked: removing the ternary dispatch, either literal-arm rule, the negated-ternary guard, or the parity walk each fails exactly the tests that claim it. One assertion I wrote survived all five mutations and was removed rather than kept. Not a recall win on crypto-trading-bot, which contains neither shape — this is precision insurance for dispatchers that do. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(routes): report every method a dispatch guard serves, not just the first (R3-8 part 1) `if ((req.method === 'GET' || req.method === 'POST') && bundlesMatch)` is two routes. The verb walk returned the FIRST verb it found, so `route_map` presented a two-method route as GET-only and `impact` on the POST path found nothing. Taken verbatim from the reporting repo's researchRunRoutes.js. `governingVerb` -> `governingVerbs`, returning a list; `findVerbInSubtree` and `verbFromTernary` likewise. A guard with several verbs emits one route per verb via the new `pushPerVerb` — they share a path and a handler but not a method, and `(method, url)` is the key every downstream consumer dedups and looks up on. A disjunction yields ALL its verbs or NONE, which also fixes an over-attribution the first-match rule had: req.method === 'GET' || req.method === 'POST' -> GET, POST req.method === 'GET' || isAdmin -> no verb The second is reached for ANY method when `isAdmin` holds. Reporting `GET` — as first-match did — describes a route open to everything as single-method, which is the direction this module treats as more expensive than saying nothing. Negated, `!(A || B)` is `!A && !B`, so it excludes verbs rather than offering them and yields none. Generic descent deliberately stays FIRST-match rather than unioning across children: an arbitrary node says nothing about how its children combine, and two verbs found under one are far more likely unrelated than alternatives. `||` is the one construct that genuinely means "either of these". Pinned against regression: the pre-existing rule that distributes ONE verb across an OR of PATHS must not start multiplying methods, and switch arms inherit the full method set. SCHEMA_BUMP 55 -> 56. Routes are parse-time output replayed verbatim from a warm cache. Free against origin/main (48). Four mutations, each failing exactly the tests that claim it: removing the disjunction dispatch, dropping the all-operands rule, allowing a disjunction at odd parity, and emitting only the first verb. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(routes): read `.match()` dispatch, and the capturing wildcard it needs (R3-8 part 2) `RE.test(pathname)` and `pathname.match(RE)` are the same test with the operands swapped. Only `.test` was read, which is why 28 of the reporting repo's 75 routes still named the shared route table as their handler rather than the module that serves them: those modules dispatch with `.match`. THE CAPTURING WILDCARD, which is the part that made the rest inert. `regexToRoutePath` accepted `[^/]+` and refused `([^/]+)` — `(` fell through to the metacharacter bail. So the non-capturing form translated and the capturing form produced nothing, and every existing test passed because every existing test used the non-capturing form. The tests were written against the implementation rather than against the corpus, and the reporting repo contains no non-capturing path wildcard at all: a dispatcher captures the segment because it needs the id. This alone also repairs the already-shipped `.test` rule. A capture around anything that is NOT one segment still bails — `(.+)` spans slashes — and the alternation is balanced, so `([^/]+` unclosed is not a match. `.match` differs from `.test` in one way that matters: its result is USED, so it is almost always BOUND, and the verb then lives in a later `if`: const runMatch = pathname.match(/^\/api\/research-runs\/([^/]+)$/) if (req.method === 'GET' && runMatch) { … } Reading the verb off the CALL would report every one of those verb-less. So a bound match records `name -> path` and the route is emitted where the binding is TESTED, once per test site — one binding tested for GET and for PUT is two routes. A reference counts only in a truthiness position (`&&`/`||` operand, or a whole `if` condition), which is what separates `if (m && …)` from `m[1]`: a read of the captured segment says nothing about dispatch and would otherwise mint a duplicate route per use of the id. A binding never tested still emits one verb-less route — the code did compute an anchored match against the path. Regexes named by a same-file const resolve too (`pathname.match(POSITION_REPLAY_RE)`), with the same ambiguity refusal the string-constant map uses: bound twice to different patterns means dropped, because a half-right regex is a wrong route. SCHEMA_BUMP 56 -> 57. Free against origin/main (48). Nine mutations, each failing exactly the tests that claim it. TWO of my own tests initially survived their mutation and were rewritten, not kept: - the non-path-receiver case had no path token anywhere in the fixture, so PATH_TOKEN_HINT skipped the file and the assertion was satisfied by a file that was never examined; - the negation case used `!m`, which never reaches the negation check at all — a `unary_expression` parent is not a truthiness position to begin with. The shape that exercises it is `!(req.method === 'GET' && m)`. A declaration-site skip written alongside them proved unreachable for the same reason and was removed rather than left to imply a hazard. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(processes): report what the detection ceilings dropped, instead of logging it at debug (W2-3) `processProcesses` has five ceilings - the entry-point trace quota, the per-entry trace budget, `maxTraceDepth`, `maxBranching` and `maxProcesses` - and every one of them fired silently. The result came back looking whole and no consumer could tell it was a sample. The code's own comment already said so: // A silently truncating cap reads as "this is everything", which is the // same class of confident-empty answer this work is about. and then only called `logger.debug`. A log nobody has enabled is not a disclosure. `stats.truncation` is additive, so every existing consumer of `totalProcesses` / `crossCommunityCount` / `avgStepCount` / `entryPointsFound` is unchanged. It carries one boolean to branch on plus a counter per ceiling, kept SEPARATE rather than summed because they mean different things: unexplored entry points mean whole flows are missing, while a depth-capped trace means a flow is present but shorter than it really is. `processesDropped` counts against the DEDUPED population, not the raw trace list - the gap between those two is deduplication doing its job, and counting it as truncation would report a permanent non-zero on every healthy repo. `truncated` is DERIVED from the counters rather than set at each site, so a ceiling added later only has to increment its own counter to be reported. Surfaced at `warn` and NOT gated on `isDev`: "823 flows" printed without it reads as the complete set, which is the confident-empty failure wearing its other face - a confident-COMPLETE one. The debug line stays for the per-entry detail it carries. Seven mutations, each failing exactly the tests that claim it, including BOTH directions of the flag: hardcoding `truncated` false fails the four positive cases, and hardcoding it true fails the nothing-was-truncated case, which is asserted first precisely so the positives cannot pass vacuously. The `walksCutByBudget` fixture gives every node exactly `maxBranching` callees so it asserts its own counter and not a neighbour's. Also fixes a defect this work exposed: 10b0c7a1 (W2-5) embedded a RAW NUL BYTE in `trace.join(...)` instead of the backslash-u escape the rest of the repo uses. It behaves identically at runtime, but `file` reports the source as `data`, and grep, git diff and code search treat it as binary - several greps against this file silently returned nothing while I was reading it. main was clean here; two other files carry the same raw byte from before this branch and are left alone. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): resolve members through a MEMBER-CALL producer's return shape (W2-1) const svc = new SignalService() const r = svc.make() return r.secretFlag // <- no edge `return-shape-members` types `r` to the producer that made it, but a member call binds the spelling `svc.make`, and slicing that to its last segment leaves `make` — a METHOD, never a callable binding in scope. The producer lookup failed and the pass declined. The limit shipped documented as needing inter-procedural receiver typing. It does not. Measured on a fixture, the pipeline had already done the hard part: - `readMake -> Method:...SignalService.make#0` already resolves as an ordinary CALLS edge, so the receiver is already typed; and - `Property:...SignalService.make.secretFlag@N:C` already exists, because R3-4 anchors a returned literal's keys to the METHOD that returns them, not only to free functions. Both halves were present and unjoined — the same shape as R3-5 itself. ADDITIVE, not a reroute. The new branch sits inside `if (producerFile === undefined)`, so it can only fire where the callable lookup already declined; every reference that resolved before resolves identically, by construction rather than by test. Nothing new is inferred. The receiver is typed by the SAME predicate that typed `r`, and it must itself resolve to a class — a receiver that cannot be typed still declines, so `make.<member>` is never matched by name across the graph. That fabrication is what the existing guards exist to stop and they all carry over unchanged: the owner must resolve, its file must match the candidate's, and `ownFilePaths` keeps the polyglot class registry from walking a JS read into a Java field. The owner segment is TWO parts for a method (`SignalService.make`) and one for a free function (`makeSignal`), which is exactly how R3-4 qualifies each. That is what separates two methods of one class returning the same key name from each other AND from a free function of that name — the fixture gives `secretFlag` three owners so a wrong resolution is detectable rather than a coin flip that happens to look right. Four mutations, each failing exactly the two tests that claim it: removing the fallback, using the method alone as the owner segment, taking the producer file from the reading file instead of the owner class, and dropping the receiver-type requirement. 3,408 resolver tests pass, including `polyglot-property-isolation`, which is the one this could plausibly break. No SCHEMA_BUMP: this is a resolution pass over ParsedFiles, not parse-time output, so a warm cache replays the same input and produces the new edges. Measured on crypto-trading-bot: ZERO new edges, byte-identical at 62,158. Its 170 `const x = new Y()` bindings are overwhelmingly built-ins (Map, Set, Promise, S3Client) rather than workspace classes whose methods return object literals — it is a module-style JS codebase. Correctness fix for class-shaped code, not a recall win on this corpus, and it should not be presented as one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): type a bare parameter from what its callers pass (W2-2) function readSpike(spike) { return spike.wickRatio } had nothing to type `spike` from, so the read fell through to the 0.5 name tier. That is the standing limit of R3-5 and, measured, by far the largest: 11,012 of 13,672 property edges on the reporting repo (81%) rest on that name guess. The two facts needed were already extracted, for a different consumer. For JS and TS among others, `callable-flow-captures` synthesizes: formal owner=readSpike binding=spike parameter-index=0 argument source=s parameter-index=0 direct-callee-name=readSpike Joining them on (callee, parameterIndex) says which cell reaches which parameter, and the argument's own binding is typed by the same `findReceiverTypeBinding` a directly-bound receiver already uses. So the parameter inherits the producer and `spike.wickRatio` resolves as evidence rather than inference. No new capture, no parse-time change, NO SCHEMA_BUMP. And deliberately not a change to the callable-value-flow solver that owns these sites: that pass is guarded by a fingerprint CORRECTNESS gate plus a timing budget, so this reads the same facts and computes its own map. AMBIGUITY DECLINES. A parameter whose callers pass different producers resolves to nothing. Picking one would fabricate at the 0.9 PRECISE tier, which no `minConfidence` floor can filter out — the same reason `buildConstantMap` drops an ambiguous constant instead of taking the first. Keyed by the formal's (scope, name), not by a definition id. The first attempt used a def and measured `paramDef=NONE`: a parameter is not reachable through `findValueBindingInScope` (its predicate is `isOwnableValueLabel`, which lists Const/Variable/Property/Static because it exists for OWNERSHIP registration, and a parameter is owned by nothing) and it is not a `local` binding either. The formal site already states the scope its parameter binds in, which is enough. Formals carry their DECLARING FILE in the key, so two same-named functions in different files cannot answer for each other — dropping it makes both go ambiguous and both readers silently lose their edge. COVERAGE, counted rather than assumed. The synthesis skips an argument that is itself a call result (an explicit `continue` in `callable-flow-captures`), so `f(makeSignal())` emits no argument site and only the bound spelling `const s = makeSignal(); f(s)` is served. That looked fatal until measured: in the reporting repo, bare-identifier arguments outnumber call-result arguments 2,563 to 50 — 51:1. Extending the shared, benched capture synthesis for the 2% case is not worth its risk. Four mutations, each failing exactly the tests that claim it: keeping the first producer instead of declining on conflict, dropping the read-site lookup, matching a formal at index 0 regardless of the argument's index, and dropping the declaring file from the formal key. Two of those could not be caught by the first fixture at all — it had a single parameter and a single consumer file — so the fixture gained a two-parameter callee and a same-named twin in a second file before they were meaningful. The test helper also had to start filtering by source FILE, or two different `readSpike` symbols merged into one count. Measured on crypto-trading-bot: 36 reads left the 0.5 name-guess tier. 26 became precise 0.9 edges (return-shape reads 1,130 -> 1,156, which is the whole delta), and 10 became honest absences — the receiver was typed, the producer's shape was known, and the member is NOT on it, so the site is claimed as disproved rather than left for the name fallback to invent an answer for. That is ~0.3% of the 11,012, and it should be reported as such. The 81% figure is the size of the PROBLEM, not of this fix: the shape requires a bound argument, a producer that returns an object literal, and a parameter read as a receiver, and that intersection is narrow. The remaining name-tier reads are mostly receivers no workspace producer types at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(processes,ci): anchor trace subsumption, cover the sink wiring, stop one bench guard hiding the rest (#2894, #2896, #2895) Three follow-ups reported against #2856 after it merged. Each was reproduced before it was fixed. #2894 — trace subsumption matched mid-identifier. `deduplicateTraces` decided whether one trace is a sub-path of another with an UNANCHORED `String.includes`, so a match could begin in the middle of a node id: 'X->AA->B'.includes('A->B') -> true and `A -> B` was discarded as redundant against a chain `A` is not a step of at all. Reproduced directly against the function before fixing. Padding both keys with the separator makes `includes` match whole steps only. Reported as measured-inert and that holds — the collision needs one node id to be a strict suffix of another at a `->` boundary, which real ids (`Function:<path>:<name>`) do not produce. Fixed anyway because the predicate did not mean what the surrounding code says it means, in a function whose entire job is deciding what to delete, and nothing pinned it. `deduplicateTraces` is exported for the test, matching how `traceFromEntryPoint` and `buildSinkFunctionSet` are already reached. The tests use bare ids because the shape cannot be built from realistic ones — which is exactly why nothing caught it. Alongside the regression case, two tests pin that GENUINE subsumption still happens, prefix and suffix, so the fix cannot degenerate into "subsume nothing" and pass the first test trivially. Mutation-checked: reverting the padding fails the mid-identifier test and only that one. The encoding assumes `->` never appears IN a node id; a C++ `operator->` would defeat the join regardless of padding. Out of scope, but the assumption is now written down where the join happens. #2896 — the sink wiring was only ever exercised through its fail-open catch. `processesPhase` reads `allFetchCalls` / `allORMQueries` off the parse output inside a try/catch that falls open to "no sinks", and every phase-level test omitted `parse` — so all of them took the CATCH branch and the success path had no coverage. `getPhaseOutput` is a raw `as T` cast, so a field rename would make the phase detect zero sinks while every test still passed, because zero sinks is what they already assert. The new test asserts the one thing only the success path can produce: a flow ENDING at the sink while a longer chain continues past it. Its control is the same graph with no `parse` dep, which must NOT produce that terminal — without the control the assertion could pass for an unrelated reason. Also asserts `processesPhase.deps` contains `parse`, so the read and the declaration cannot diverge, and that a parse output missing those fields still fails open rather than losing every process. Mutation-checked, including the exact drift scenario reported: renaming `allFetchCalls` at the read site, dropping `parse` from `deps`, and passing no sinks to `processProcesses` each fail exactly the test that claims them. #2895 — a failing bench guard aborted the job and masked every later guard. Every step in the benchmarks job was fail-fast, so the first failing `--check` aborted it and the rest reported `skipped`, which reads identically to "nothing to do". Audited over 13 runs on #2856: the job succeeded zero times and the last two guards executed zero times for the life of the PR, while two reviews read the checks summary and saw nothing wrong. Both guards did in fact pass — that was luck, not verification. `if: ${{ !cancelled() }}` on all ten steps after the first, so one stale baseline reports one red step instead of hiding nine. `!cancelled()` rather than `always()` so an explicit cancel still stops the job instead of running seven minutes of benchmarks nobody is waiting for. The two steps easiest to miss are covered: `Receiver-resolution drop guards`, whose `run:` sits twenty lines below its `name:` behind a long comment, and the final `Cross-language pipeline benchmarks` step, which is not a `--check` and so falls outside any grep for one — and is one of the two that never ran. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(parse): capture a fetch call site even when its URL is not a literal (#2897) The `fetch` rule required the argument to be a string or template literal: arguments: (arguments [(string (string_fragment) @route.url) (template_string) @route.template_url]) so `fetch(url)` with a variable matched nothing at all. Measured across this repository's own TypeScript sources: **44 of 47 fetch calls pass a variable**, so 94% produced no site. That is what makes R3-6 look inert. The sink set is built entirely from `allFetchCalls` / `allORMQueries`, so a function performing an outward call through a computed URL was never a sink, no flow could terminate there, and the sink-first ranking rule never changed an ordering. The feature was fine; the signal underneath it was almost always empty. The URL alternation is now OPTIONAL, so one match covers both shapes. The R3-6 sink set needs only WHERE the program reaches outward, not where to. Route linking is untouched, by construction rather than by hope: `processNextjsFetchRoutes` normalizes the URL first and skips anything that yields nothing, so a URL-less entry cannot mint a FETCHES edge. Verified on this repo — FETCHES went 8 -> 9 across the change, i.e. the widening added sink sites without inventing route edges, which was the one real risk here. Tested in BOTH JavaScript and TypeScript, since the rule is duplicated in each query block and fixing one would have left the other blind: - a variable argument is captured, with no URL <- the regression case - a computed argument (`fetch(buildUrl(), {...})`) likewise - a literal URL is still captured WITH its URL <- route linking depends on it - a template URL likewise - exactly ONE site per call — an optional alternation must not make a literal match twice, which would double-count the site and could mint two edges - `prefetch('/x')` is still not a fetch Mutation-checked: restoring the mandatory alternation fails six of the twelve, three in each language. SCHEMA_BUMP 57 -> 58. Parse-time capture output is replayed verbatim from a warm cache, so without the bump an already-indexed repo keeps its empty sink set and the fix looks inert — which is the failure this constant exists to prevent, and would have reproduced the very symptom being fixed. Not addressed here, and worth stating: this widens `fetch` only. The reporter's broader point stands — anything keyed on FETCHES / QUERIES is only as good as the extraction underneath it, and the ORM side has not been measured. A guard that fails when a corpus known to contain outward calls yields zero sites is the right follow-up; this change makes such a guard meaningful rather than tautological. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(bench): re-baseline receiver-resolution for the two fixtures this PR adds `receiver-resolution --check` failed on: countArm.totalDropsAllKinds: 140 -> 148 countArm.bySiteKind.write: 11 -> 19 Investigated before touching the baseline, because a guard that exists to catch unexplained movement should not be silenced by an unverified story. WHAT IT IS: the count arm runs the real pipeline over a corpus that includes `test/fixtures/lang-resolution/`, and this PR adds two fixtures there — `member-call-producer` (W2-1) and `parameter-producer` (W2-2). Each returns an object literal with two keys, and a producer writing its own returned key is a write site the receiver recorder logs. Four each, eight total. Attributed by dumping the individual drops rather than reading the aggregate: member-call-producer/src/producer.js secretFlag, wickRatio (2 lines) = 4 parameter-producer/src/producer.js source, wickRatio (2 lines) = 4 The eleven drops already in the baseline are all `javascript-object-properties` fixtures of exactly the same shape, so the new ones are not a new KIND of drop — they are more of one the baseline already records. This is the first case the guard's own failure message names: "a fixture was added". WHAT IT IS NOT: `callDrops` — THE gate number, and `call`-only by deliberate design because reads and writes "would inflate it" — is unchanged at 102. `read` drops unchanged at 27. The SHAPE ARM shows no drift at all: no receiver spelling moved between RESOLVES / VISIBLE-GAP / INVISIBLE-GAP, so no resolution regressed. HOW IT WAS ISOLATED, since the first attempt was misleading and the record is worth having: reverting `return-shape-members.ts` alone did NOT reproduce it and pointed away from W2-1/W2-2. Only a commit-level bisect was trustworthy — `origin/main` OK, W2-8 OK, W2-3 OK, then W2-1 +4 and W2-2 +4, which matches the fixture count exactly. A file-level revert leaves the fixtures in the tree, and the fixtures are the cause. The update is two numbers. Nothing else in the baseline moves. Worth noting where this failure became visible at all: under the fail-fast benchmarks job it would have aborted the run and shown the five guards after it as `skipped`. It is legible here because #2895 — fixed in this same PR — now lets every later guard run. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(analyze): stop `--pdg` runs reporting a healthy index as INCOMPLETE Every `gitnexus analyze --pdg` reported a graph-write collapse and exited 1 on an index where every row had persisted. Reported by a user hitting it on a real repo; introduced by this PR's own W2-6(d). Repository indexed INCOMPLETELY the pipeline produced 200,501 relationships but only 64,764 are readable The index was complete: 200,190 rows present, 109,905 PDG and the rest structural, all queryable. WHAT WENT WRONG. W2-6(d) made the persisted side count STRUCTURAL rows only — correct, and the reason is in its own comment: PDG writes into the same table, so counting everything let PDG surplus mask real structural loss. But the expected side kept using `graphEmitManifest.totalRows`, and that is a BUFFER-POOL SIZE HINT which counts every streamed row. PDG streams through that same sink, so the check compared a structural-plus-PDG expectation against a structural measurement. On any repo with a PDG layer that is a guaranteed false collapse. It compounds rather than merely misreporting: the run stamps `graph-write-collapsed`, and W2-6(a)'s rebuild trigger — added alongside it — forces a full re-analyze next run, which collapses again. A permanent rebuild loop, on an index that was never damaged, at ~100s a cycle. MEASURED RATHER THAN ASSUMED, because the first attempt was wrong. I first subtracted PDG edges RESIDENT in `graph.relationshipCount`, rebuilt, re-ran the failing command and got byte-identical numbers. Instrumenting the three terms showed why: relationshipCount=20,825 graphManifestTotalRows=179,676 pdgEmitManifest=absent residentPdgInGraph=0 PDG is not resident in the graph AND has no separate manifest — it streams through the ordinary `GraphEmitSink`. The reverted attempt is not in this diff. THE FIX. A pair key cannot separate them: it is `From|To` NODE LABELS, and a CFG edge shares `Function|Function` with CALLS. Only the write path sees `relationship.type`, so the sink now counts a `structuralRows` subtotal there and publishes it on the manifest. `totalRows` is unchanged — it still sizes the buffer pool, which is what it was for. WHY THIS SHIPPED UNCAUGHT, and what changed about that. The wiring test kept a LOCAL MIRROR of the expected-count expression "because the production expression is inline in a 3000-line function". A mirror cannot catch a term the original got wrong. That expression is now an exported `computeExpectedStructuralRelationships` which production calls and the test imports. It also takes the MANIFEST rather than a pre-selected number, deliberately: the defect was choosing the wrong FIELD, and a numeric parameter leaves that choice at a call site no unit test can reach. Verified — with the helper taking a number, reverting to `totalRows` failed nothing; taking the manifest, the same revert fails four tests. Verified end to end on the reported command: `analyze --force --embeddings 0 --pdg` now exits 0 with "indexed successfully", 86,963 nodes / 200,217 edges, and the run clears the stale collapse stamp. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(routes): scope match bindings, and intersect ternary conjunctions Two ways the dispatch-guard walk minted a route that does not exist — the one thing this module's header says is worse than missing one. MATCH BINDINGS WERE KEYED BY BARE NAME, FILE-WIDE. `collectFromMatchBindings` walked from `tree.rootNode` and resolved `matchBindings.get(node.text)` at every identifier in a truthiness position, so a same-named binding in ANOTHER function answered for it. The poison check only fired on a second REGEX match with a different URL; a non-match binding never entered `collectFromRegexDispatch`, so nothing refused it. Reproduced: function handleReplay(req, res) { const m = pathname.match(/^\/api\/live\/positions\/([^/]+)\/replay$/); if (req.method === 'GET' && m) { … } } function handleSettings(req, res) { const m = req.headers['x-mode']; // unrelated value, same name if (req.method === 'DELETE' && m) { … } } GET /api/live/positions/{param1}/replay handler=handleReplay correct DELETE /api/live/positions/{param1}/replay handler=handleSettings FABRICATED Wrong in method, handler and line. `m`, `match`, `result` are the ordinary names here. Two ways the truth was then lost: the fabricated route is VERBED, so `reconcileDispatchGuardRoutes` kept it and dropped the true verb-less one — the #2856 `/api/report` shape, through the channel this series added — and `tested` was name-keyed too, so the tail loop suppressed the real binding's own honest verb-less emit before reconciliation ever ran. `matchBindings` and `tested` are now keyed on (enclosing function, name). `enclosingFunction` is extracted from the walk `enclosingHandlerName` already did, so there is one function-boundary mechanism, not two. A second declarator for a key refuses it, and an assignment refuses the name in its own scope and every enclosing one. `buildRegexConstantMap` refuses a name rebound to anything that is not a regex literal, closing `let RE = /…/; RE = buildDynamic(req)` and the `new RegExp(prefix + '/x')` twin. A use resolves only within its own function. Resolving outward would need a complete declaration model — params, imports, catch bindings — and a miss there fabricates exactly the route this fixes. Declining costs the verb, not the path. THE TERNARY TOOK FIRST-MATCH WHERE THE ALGEBRA IS INTERSECTION. The docblock proves `c ? A : false ≡ c && A` and says "both hold, so search both", but `firstNonEmpty` returned one operand's set unintersected: (req.method === 'GET' || req.method === 'POST') ? (req.method === 'POST' || req.method === 'PUT') : false emitted GET and POST only POST is reachable req.method === 'GET' ? req.method === 'POST' : false emitted GET, unsatisfiable `intersectVerbs` replaces it for both conjunction shapes. An empty side still yields to the other — "names no method" is not "admits none", which is what the `isAdmin && POST` fallthrough is for — but two non-empty sides intersect, and an empty intersection is an unsatisfiable guard that yields no verb. Both changes strictly REMOVE routes, so SCHEMA_BUMP 58 -> 59: routes are parse-time output replayed verbatim from a warm cache, and without the bump an indexed repo keeps serving the fabricated verbed route while the fix looks implemented. 10 tests added, 9 of which fail without the change. All 86 existing assertions pass unchanged; none was weakened. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LZu3G5USo5Rs9myaaxVWjK * fix(scope-resolution): bind a type parameter only inside the scope it opened W2-8 captured `@declaration.type-parameters` on EVERY `type_alias_declaration`, but an alias becomes a SCOPE only when its value is an `object_type` (`typescript/query.ts:149`). For a union, array, conditional, mapped, tuple or function alias there is no scope, so the def — now carrying `typeParameters` — attached to the innermost enclosing scope, which is the MODULE. And `typeParameterNamesInScope` folds each scope's set from its PARENT'S, so the name landed in every scope in the file. The `USES` guard then deleted every edge whose target had that simple name: export interface Result { ok: boolean } export type Maybe<Result> = Result | null // one ordinary line export function readResult(r: Result) { … } // its USES edge is DELETED Silent data loss, in the edge class whose whole purpose is answering "what breaks if I remove this field?". Measured: adding two scope-less generic aliases emptied the fixture of USES edges entirely. The existing fixture could not see it — it wrote `type Box<Result> = { held: Result }`, the ONE alias form that opens a scope. `typeParameterNamesInScope` now reads a def's `typeParameters` only when that declaration OPENED the scope owning it: `scope.kind !== 'Module'` and the def-id position equals the scope range start, via the canonical `definitionIdPosition` rather than slicing the id. That is the same alignment test `pickCallerCallableDef` uses to tell a closure from a nested function, and it is language-neutral — it also covers `function f() { type W<Result> = Result[] }`, which a module-scope-only stopgap would miss. Every language populating the capture was audited (ts, java, csharp, kotlin, rust, cpp): all anchor it on a declaration that IS a scope node, including C++ where the capture rides `template_declaration` but the anchor is the inner `class_specifier`. Go uses a separate sidecar. The TypeScript non-object alias was the only mismatch in the codebase. `query.ts` is untouched. THE GUARD ALSO SAT AT THE WRONG LAYER, which forced three defects at once. It keyed on `edgeType === 'USES'` — and `mapReferenceKindToEdgeType` maps THREE kinds there, `type-reference`, `value-ref` (#2437) and `macro` (#1934) — and, because `Reference` carries no spelled name, substituted the resolved def's name via `simpleNameOfDefId`. So `import { Result as ApiResult }` inside `function unwrap<Result>()` deleted a REAL edge, while a namespace-qualified target (`Host.Result`) kept a FALSE one, and a positional `@row:col` suffix broke the last-colon parse outright. Moved to `lookupForSite`'s `case 'type-reference'` in `resolve-references.ts`, which has the spelled `site.name` and the reference kind in hand. One line closes all three, deletes `simpleNameOfDefId` — a byte-identical duplicate of `simpleNameOfGraphId` — and removes the only `graph-bridge/` -> `scope/` import in that directory. Honest scope: all three sub-defects are real in the code but none is observable end-to-end today (`value-ref` never reaches this path; TypeScript emits no cross-file USES for a type annotation at all — a separate pre-existing gap). Those arms are labelled forward guards in the test rather than claimed as repros. Fixture grows 1 file -> 4; 3 of 9 assertions fail without the change. The scope-capture TypeScript fingerprint moves for FIXTURE-CORPUS GROWTH ONLY, with per-file accounting that sums to the delta and JavaScript unchanged as the control — see the `_rebaselined_` key. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LZu3G5USo5Rs9myaaxVWjK * fix(scope-resolution): refuse an ambiguous formal, stop the walk at the nearest binding Two ways W2-2 typed a parameter from the wrong caller, both at the PRECISE 0.9 tier — above every `minConfidence` floor, so nothing downstream can filter them. `formals` WAS LAST-WRITE-WINS. The key is (filePath, ownerName, parameterIndex), `ownerName` is a bare identifier, and `emitFormalFacts` emits one site per parameter of EVERY function collected, nested functions and class methods included. A plain `.set` let two same-named callables in one file collide — a free `parse` and a nested `parse`, a free `apply` and `Runner.apply` — so the last one visited won, fabricating an edge on the loser and leaving the genuine consumer untyped. The file's own comment covers only the cross-FILE axis. The correct shape was thirty lines below, in the `producers` map, which does `producers.delete(cell); conflicted.add(cell)`. `formals` now refuses the same way: a key claimed by two DIFFERENT parameters is deleted and recorded, so a third same-named formal cannot re-claim it. Re-stating the same cell is not a disagreement, so a benign duplicate capture cannot poison a real key. THE SCOPE WALK CLIMBED PAST A NEARER BINDING. The docblock claimed it stops at the first scope carrying the name, but it consulted only `parameterProducers` — a shadowing `const`, a catch binding or an arrow parameter is not in that map, so the walk went straight past it to the enclosing formal: function readSpike(spike) { … items.map((spike) => spike.wickRatio) … } typed the ARRAY ELEMENT from the outer parameter. `parameterProducerFor` now stops at the first scope that binds the name AT ALL — reading the scope's own tables, the same channels and the same reasoning as the sibling `isNamespaceNameShadowed` — and then stops at a Function boundary. That boundary is what covers the anonymous arrow: `collectFunctions` drops a callable it cannot name, so an anonymous arrow emits no formal site and its scope looks empty while in fact rebinding the name. The cost — a closure genuinely reading an enclosing parameter now declines — is documented as the deliberate trade. No cycle guard, deliberately and with the reason stated: both constructions of `indexes.scopeTree` validate through `buildScopeTree`, which enforces strict parent-contains-child ranges, so a cycle needs a scope strictly containing itself. A per-site Set on every read/write site in the repo would defend against a state the builder rejects. 5 fixtures, 5 assertions; 4 fail without the change and the control passes both ways. Still uncovered and not faked: a `for (const x of …)` binder shadow — the binder lives in the loop header, so JS emits no scope to stop at and no Function boundary intervenes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LZu3G5USo5Rs9myaaxVWjK * fix(analyze): measure one population in every config, split the stamp on the verdict `1b41c9df6` fixed the collapse check for the STREAMED configuration by giving the sink a `structuralRows` subtotal. It does not cover the other one. `resolveStreamGraphEmit` and `resolveStreamPdgEmit` both open with a `force === true` gate, so a run without `--force` streams nothing: there is no manifest, `structuralRows ?? 0` contributes 0, and `scope-resolution/pipeline/run.ts:1222` (`input.pdgEmitSink ?? graph`) writes PDG into the ordinary in-memory graph, where `relationshipCount` counts it. And `isIncremental` requires an existing meta, so a FIRST run is a full write and the check runs. A first-time `gitnexus analyze --pdg` on a fresh repo therefore compared structural+PDG against structural and exited non-zero with "Repository indexed INCOMPLETELY" on a healthy index. MEASURED, not assumed — `runScopeResolution({ pdg: true })` with no sink: pdgEmitSink = absent (non-force shape) relationshipCount = 1 residentPdgInGraph = 1 byType = [["CFG",1]] The prior `residentPdgInGraph=0` was taken on a `--force` run, where `input.graph` IS the sink; it never spoke to this case. `graph-collapse-wiring.test.ts` had pinned the gap, asserting a PDG-inclusive in-memory count was a valid structural expectation. `countStructuralRelationships(graph)` filters `PDG_EDGE_TYPES` over `forEachRelationshipFields` — the same predicate the sink uses for `structuralRows` and the adapter for `structuralEdges` — so all three terms measure one population in every configuration. Declining whenever `pdg && !streaming` was rejected: that is the DEFAULT PDG shape, so the guard would be off for every non-force run including the only full write most users ever do. An unscannable graph (mocked pipelines) yields NaN, the same fact the old `undefined + rows` produced and one `detectGraphWriteCollapse` already documents as expected input. THE THREE-WAY STAMP WAS A TWO-WAY. The comment enumerated collapse -> stamp, healthy -> clear, no verdict -> carry forward, but the code split on the WRITE MODE. `graphWriteCollapsed` is undefined for two different reasons, and one of them is "the structural query threw" — so on a full run where the count could not be READ, the code took "healthy, clear it" and erased a stamp recording real edge loss. Run 3 then printed "Already up to date" forever: the exact failure the comment says it fixed, reachable through the new code's own `catch {}`. `detectGraphWriteCollapse` now returns `'collapsed' | 'healthy' | 'unmeasurable'` with a reason, and `selectPersistedCollapseStamp` is a pure exported function production calls. Two boundaries worth naming: `expected === 0` is unmeasurable (its own docstring calls it "could not report a total"), but the small-repo exemption and a cleared ratio are HEALTHY — both counts were taken. Making the exemption a non-verdict would leave a stamp unclearable on any repo that shrank below 100 edges, relocating the wedge rather than fixing it. `getLbugStats` now reports `structuralEdgesError` and warns, and `run-analyze` falls back to `stats.edges` only when the run had no PDG layer, where the two are equal by construction. With `--pdg` on there is no substitute, so the absence becomes an explicit unmeasurable verdict — which preserves the stamp. 13 tests added; 8 fail without the change. The integration suite now seeds a CFG row and asserts `edges` moves while `structuralEdges` does not — the exclusion filter was previously unexercised, its own comment conceding "structural == total here". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LZu3G5USo5Rs9myaaxVWjK * fix(server): check the collapse before publishing the index W2-6 marked a collapsed run's job `failed`, but the check ran INSIDE `.then(() => backend.init())` — after the publish. `LocalBackend.init()` is the publish step: it refreshes the registry and atomically swaps the in-memory repo map every MCP tool and HTTP route resolves through, and its `validate` pass prunes only entries whose metadata is provably gone, so it can publish but never quarantine. The known-incomplete database was therefore live and queryable before the job was ever marked failed — the job status was a label on a published index, not a gate. The pre-existing comment two lines above says so outright: "the repo is actually queryable when the client receives the SSE complete event." `backend-client.ts` routes `failed` to `onError` and never calls `onComplete`, so the UI showed an error toast while every query against that repo answered from the incomplete graph — precisely the confident-wrong-answers failure this guard exists to prevent. The collapse branch now returns before publishing; the healthy path publishes via a nested `backend.init()` so the trailing `.catch` still converts init failures into the same message. `closeDbHandle()` runs on both paths — it is eviction, not publication, and the worker rewrote the DB files regardless of outcome, so skipping it would leave a stale pre-rewrite handle. Honest limit, stated in the error string rather than overclaimed: this keeps a FIRST-TIME analyze unpublished, which is the UI's main flow. On re-analysis of an already-published repo the existing map entry survives and points at the same storagePath. A real quarantine needs an un-register hook on `LocalBackend`, which does not exist today — follow-up. `'partial'` was considered and rejected on evidence: it is not a status. It is an embedding-specific detail object in the `updateJob` allowlist; the status union excludes it. Adding it would make `isTerminalJobStatus` false, so `sse-progress` never writes a terminal frame and never calls `res.end()` — the stream hangs open — while `backend-client` falls through to `onMessage` and `api.ts` spins the full hold-queue timeout. `failed` at least terminates. The failure branch also now sets `repoName`, which only the success path did. First tests this file has ever had: 4, of which 2 fail without the change. They assert the ORDERING, not just the final status, and build the worker message by calling the production `projectAnalyzeResultForIpc` so a field rename breaks the test instead of silently disabling the branch. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LZu3G5USo5Rs9myaaxVWjK * fix(processes): count the entry-point cap, and make the disclosure proportionate W2-3 added a truncation disclosure and then missed the largest ceiling it was written to report. `findEntryPoints` ends `.slice(0, 200)` and `entryPointsUnexplored` counted against the POST-slice list, so candidates 201..N were invisible — while the derivation docblock claimed "a new ceiling added later cannot be forgotten here". An existing one was. On this repo's own corpus the new counter reads 780 of 980 candidates never ranked in. `entryPointCandidatesDropped` reports the pre-slice count, folded into `truncated`, with `ENTRY_POINT_CANDIDATE_LIMIT` extracted and `findEntryPoints` taking the same optional out-parameter `traceFromEntryPoint` already uses. Its return contract is unchanged. THE WARN FIRED ON EVERY RUN. At the shipped defaults — only `maxProcesses` is overridden — `calleesDropped` fires for any function with 5+ callees and `tracesDepthCapped` for any chain deeper than 10, so an ungated `logger.warn` was constant background noise, and a warning that always fires is one nobody reads. The split is the module's own, from the `ProcessTruncationStats` docblock: "unexplored entry points mean whole flows are missing, while a depth-capped trace means a flow is present but shorter than it really is." So `warn` iff whole flows are absent — candidates dropped, entry points never traced, or flows dropped at `maxProcesses` — and `debug` for a run truncated only in depth or breadth. `stats.truncation` still carries all six counters; the machine-readable channel is unchanged, only the log level moves. `entryPointCandidatesDropped` stays in the loud set deliberately: it is the only ceiling that GROWS with repo size, while the other two can only fire while `maxProcesses` is small enough to bind, so gating on those alone would go silent on exactly the large repos where 200-of-several-thousand is the thinnest sample. The message leads with the ratio so the line carries a fact, not an alarm. THREE COMPARATORS ALLOCATED PER COMPARISON, in the function whose own comment explains the hoist that removed this shape (`deep_chain` 1233 -> 102 ms). Measured here: +99 ms once per analyze at 80k functions — small, because `n` is capped at 200 entry points x a 12-trace budget = 2,400 traces regardless of repo size. Worth fixing anyway: 23,851 comparisons cost 70,524 joins. One shared `sortByDepthThenPath` (Schwartzian, key built once per trace) now serves all three sites, and `rankedByInterest` additionally hoists the `isSink` test that ran twice per comparison. It also settles a separator inconsistency: `deduplicateByEndpoints` joined on a SPACE while `traceOrderKey` used NUL, and node ids embed file paths, so two different traces could produce the same key and the tiebreak fell back to the insertion order it exists to remove — the same hazard this series' own `->`-padding fix addresses. Order identity is pinned by a seeded 200-trace corpus asserting the new sort equals the old one exactly. 11 tests added, 9 failing without the change, including two end-to-end insertion-order arms. The W2-5 determinism block is unregressed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LZu3G5USo5Rs9myaaxVWjK * fix(docs): restore the agent guidance, and put it in the generator that deleted it Commit `9e602aef0` — whose message is entirely about the fetch capture — also regenerated the machine-managed `<!-- gitnexus:start -->` block from a local non-`--pdg` index, deleting from both AGENTS.md and CLAUDE.md: - the whole `MUST treat risk: UNKNOWN as unresolved, not as low` bullet - the `pdg_query({mode:"controls"/"flows"})` bullet - the `mode: "pdg"` text on the impact bullet - `…never read UNKNOWN as an all-clear…` from Never Do and regressing the stats 248612/565510/918 -> 42853/135955/758. All four document SHIPPED features: `pdg_query` at `mcp/tools.ts:675`, dispatched at `local-backend.ts:2233`; `mode: "pdg"` at `tools.ts:448`; `riskNote` at eight sites. It matters more than a docs nit because the SAME series makes `UNKNOWN` dominate a mixed candidate set (`local-backend.ts:6058`) — correct, and it makes UNKNOWN far more common. The surviving rule only warns on HIGH/CRITICAL, so a set measuring CRITICAL now reports UNKNOWN and that rule no longer fires, while the rule that covered the gap was deleted in the same commit range, from all three files agents actually read. ROOT CAUSE, which is why restoring the files alone would not have held. `cli/ai-context.ts` is the template. The `pdg_query` and `mode: "pdg"` text IS in it, correctly `hasPdg`-gated — a non-PDG analyze SHOULD drop those. The `risk: UNKNOWN` rules were never in the template at all: they had been hand-added INSIDE the machine-managed region, so every `gitnexus analyze` on any repo silently deleted them. This was the second occurrence; #2856's `8f8261021` was the first. Both lines are now generated unconditionally — they describe impact's risk semantics, which are not PDG-dependent — so regeneration restores them instead of removing them. AGENTS.md and CLAUDE.md are byte-identical to origin/main again, and the fixed template reproduces that block exactly for `hasPdg: true` plus the real stats. `.claude/skills/gitnexus-guide/SKILL.md` regains the "Inline staleness signal" section for a live feature (`local-backend.ts:921`, `:1017-1024`, `:1995`); the npm mirror's lack of it is pre-existing drift and is left alone, so the new sync guard is scoped to the canonical and plugin copies. Guards added, both demonstrated failing against the unrestored files: the managed block must contain the UNKNOWN policy and its Always-Do/Never-Do bullet counts must not fall below a floor, and `generateGitNexusContent` must render both lines for `hasPdg` true AND false while keeping `pdg_query` gated. The existing fragment lists could never have caught this — they assert presence, and this was a deletion. One deliberate loosening, called out rather than buried: the restored text pushes `ai-context.test.ts`'s block-size ratio past 0.55, so it moves to 0.65. That test argues against exactly this nudge-the-number pattern. The defence is that the wording is origin/main's own and the 0.55 budget was calibrated against a block already missing it; trimming shipped guidance to fit a budget would be the wrong direction.

DuduPhudu	223ac7010d	feat: close reported graph blind spots in reference resolution, analyze and storage (#2856) ... * fix(mcp): report UNKNOWN risk when an upstream impact walk finds no callers `risk: LOW` asserts "safe to change" — a claim ABOUT callers. An upstream walk that resolved none has nothing to base it on: the symbol may be genuinely unused, or reached only through a reference class the index does not record (a property access on a plain object, a bare-identifier read of a module-scope const). Seeding LOW from an empty result is the false-safe signal `anyKnownRisk` already refuses to emit on the ambiguous-candidate path, and that #2687 removed by making an undetermined impactedCount `null` rather than `0`. Zero-caller upstream results now report risk UNKNOWN with a riskNote saying absence of edges is not evidence of disuse. Downstream is untouched: an empty downstream walk reports resolved callees, not safety. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(javascript): emit ACCESSES for bare-identifier reads of module-scope consts A constant read only as a bare identifier — `Math.max(LIMIT, n)`, a default parameter value, `return LIMIT` — minted no reference site at all, because JS captured only `@reference.read.member`, which requires a receiver a bare identifier does not have. So "who uses this constant?", the question behind every dead-code trim and constants refactor, answered with a confident zero in both directions. The rest of the machinery was already in place: `FIELD_KINDS` accepts `Const`, the scope query already declares it via `@declaration.const`, and `read` maps to ACCESSES for any resolved target. This adds the missing capture in VALUE POSITIONS ONLY (call arguments, default-parameter values, return statements) — a blanket `(identifier)` rule would mint a site for every token in the file, which is unaffordable at repo scale and would keep alive the block-local symbols `pruneLocalSymbols` exists to drop. Cross-file readers are NOT yet covered: the site exists and a call through the same import statement resolves, but a value-kind def does not link across the import edge. Recorded as a todo with the investigation. PARSE_CACHE_VERSION bumped 44 -> 45: this is parse-time capture emission, so a warm cache replays the pre-change capture set and the new edges never appear — observed directly, a full `analyze --force` produced a byte-identical graph until the cache was cleared by hand. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(javascript): pin A1/A5 plain-object property acceptance criteria Fixture plus todo specs for the four shapes plain-object property access has to answer: object-literal keys indexed as Property nodes, a read through the holding variable, a property WRITE, and a read through an untyped param. Records the investigation so the work is resumable: the parse-query pattern scoped to literals bound to a variable matches correctly (verified against the raw JAVASCRIPT_QUERIES), but no Property node reaches the graph and local-symbol-pruner is not the cause — it drops only Const/Variable/Static. The remaining gate is in the parse worker's node-creation path. No production code — specs only, so the suite stays green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(javascript): index object-literal keys of a named object as Property nodes Idiomatic JS models configuration as an object literal, not a class, but Property definition nodes existed only for DECLARED CLASS FIELDS. A config field therefore had no symbol at all: `context({name: 'exitMinAtrMult'})` answered "not found" for a field read and written throughout a live code path, and ACCESSES had no target to point at. Both halves are added for keys of a literal BOUND TO A VARIABLE — the parse query mints the graph node, the scope query mints the def the resolver can aim at. Unbound literals are deliberately excluded: an inline call argument or a JSX prop bag is call-site data, not a named surface other code references, so a node per key there would add volume without adding an answerable question. This lands the definition-node half only. The ACCESSES edges still require receiver resolution — typing the const that holds the literal to the literal's scope for the precise case, and name-based matching at reduced confidence for the untyped-param (option bag) case. Both are recorded as todos with the mechanism each needs. Also records a trap that cost a wrong conclusion: under vitest the parse worker runs the BUILT dist code (parse-impl resolves parse-worker.js, absent under src/, and falls back to dist), so parse-query changes are invisible to tests until `npm run build`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(cache): move the SCHEMA_BUMP pin to 45 The pin is the guard that makes two branches claiming one cache-schema number fail loudly instead of silently serving each other's entries, so a bump is only half-done until the pin moves with it. The bump itself landed with the JavaScript bare-identifier captures; this is the other half. Caught by the guard working exactly as designed — the suite failed with "expected 45 to be 44" rather than letting a mismatched pair through. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): resolve plain-object property access by unique name Idiomatic JS reads configuration off an object whose receiver cannot be typed — an options bag passed as a parameter, a destructured handle, an imported literal. No precise pass resolves those, so a field read and written across a live code path produced no ACCESSES edge at all and "who reads this setting?" answered a confident zero. A last-resort pass runs after every precise pass and sees only what they left behind. For each still-unresolved read/write site it asks whether exactly ONE Property in the workspace carries that name. If so the read almost certainly means it. If two or more do, nothing is emitted and the site is COUNTED as ambiguous — a guess between them would be a coin flip, and a wrong edge in the pre-edit safety gate is worse than a missing one. Uniqueness is the right gate because it recovers exactly the names worth recovering: distinctive domain fields (exitMinAtrMult, bookNotionalUsdt) are unique in a repo and resolve, while generic keys (id, name, data) are not and are skipped — which is where name matching would over-connect. Bounded four ways: - Confidence 0.5, the global tier, with the inference named in the reason, so a consumer can filter inferences without losing scope-resolved edges. - Never second-guesses a precise result: sites already resolved are excluded, because first-write-wins stops a duplicate but NOT a second edge to a different target. - Honors `fieldFallbackOnMethodLookup`. A statically-typed language opts out of name matching precisely because it over-connects; inferring an ACCESSES edge by name is the same claim and must obey the same opt-out. - Requires an explicit receiver — a bare identifier is not a property access, and matching one by name would link a local to an unrelated key. Indexes graph nodes rather than scope defs because an object-literal key mints a Property NODE but no scope-resolution DEF: `localDefs` and `scope.bindings` are both empty for exactly the population this serves. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(analyze): record a collapsed graph write instead of reporting fresh The dangerous half of a broken refresh: metadata IS written, so the index reads as fresh, hooks re-arm, and every tool answers from a graph missing most of its edges — indistinguishable from a codebase that genuinely has no such relationships. Reported in the field as edges collapsing 23009 -> 2170 and as a CodeRelation table that never materialized. `analyze` now compares the relationship count the pipeline PRODUCED against what the DB hands back after the write. Both numbers are already in scope at the same point, so the shortfall is provable rather than inferred — no comparison against the previous index, which cannot distinguish a failed write from a repo that legitimately shrank. A missing relation table needs no special case: it reads back as a persisted count of zero. On a collapse the run records `graphWriteCollapsed` in metadata, which `getIndexIncompleteReasons` turns into `graph-write-collapsed` so status and the MCP resources report the index INCOMPLETE rather than fresh. A ratio, not equality: some relationship types do not round-trip one-for-one and `--pdg` writes MORE rows into the same table, so demanding equality would fire on healthy runs. Only a collapse is a defect. Fail-safe when the expected count is unavailable — an implementation that offloads relationships out of memory may not be able to report a total, and a false "your index is broken" is worse than a missed one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(ingestion): qualify object-literal Property ids by their owning object Two config objects in one file that share a key name generated the same `Property:<file>:<key>` id and COLLAPSED INTO ONE node, so two distinct settings became a single symbol. Worse, the merged name then looked workspace-unique to name inference, which happily resolved reads of it to a node representing both — a wrong edge in the pre-edit safety gate, which is precisely what the unique-name pass is bounded to avoid. `objectLiteralOwnerInfo` already existed for exactly this ("so two constructors in one file that both define `bar` stay distinct nodes") but was gated to `Method`. `Property` now opts in. `findObjectLiteralBindingInfo` returns `ownerName` only when asked. Its `Method` ids must stay byte-identical — qualifying them would rewrite every object-literal method id in every indexed repo — while object-literal KEYS, indexed only since A1/A5, have no such history to preserve. Found by a test written for the ambiguity path rather than by review: the suite reported one node where two were expected, and an edge where none should exist. Both are now pinned, along with the detection boundaries of the B2 collapse check, which was previously an untestable inline expression and is now a pure function. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(typescript): index type aliases and shape members as symbols A TS frontend models its API contracts as `type X = { … }` and `interface`, so a field on one is exactly what "who breaks if I remove this?" is asked about. Three gaps made that unanswerable, all in the TypeScript queries: 1. No `type_alias_declaration` -> `@definition.type`, so an alias minted NO NODE AT ALL and a context() lookup on an exported contract type answered "Symbol not found". TypeScript was the ONLY language missing this — Rust (type_item), Kotlin (type_alias), Swift (typealias_declaration) and Dart all emit it. The alias was declared for scope resolution but never became a graph symbol. 2. No `property_signature` in the parse query, so INTERFACE members minted no Property nodes either — the upstream report's "class/interface index fine" holds only for the type, not its fields. 3. No `property_signature` in the scope query, so even with nodes present the resolver had no member declaration to aim at. Its sibling `method_signature` -> `@declaration.method` already existed; only properties were missing. Interface bodies and object-type aliases both spell members as property_signature, so one pattern per query covers both shapes. Lands the SYMBOLS, not yet the ACCESSES edges: the shape is already a class-like scope and now has member declarations, but no edge forms — the remaining link is owner/type-binding, recorded as todos with the diagnosis. Note TypeScript sets fieldFallbackOnMethodLookup:false, so unlike JavaScript there is deliberately no name-based fallback here; the precise path is the only route by design. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(golden): accept interface members in the mini-repo snapshot Drift is entirely the new TypeScript shape-member indexing: the fixture's three interfaces (ValidationResult 2, DbRecord 3, LogEntry 3) contribute exactly 8 Property nodes, each with exactly one HAS_PROPERTY owner edge. Verified before regenerating rather than after: every pre-existing count is untouched (CALLS 9, IMPORTS 12, DEFINES 16, HAS_METHOD 1, MEMBER_OF 12, STEP_IN_PROCESS 12), so nothing was rewired — the digest moved only because 8 edges were added. The fixture's inline `return { valid: false, … }` literals correctly produced nothing, confirming the object-literal rule stays scoped to variable-bound literals. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(analyze): never report a collapse from a non-numeric count The B2 check reported healthy runs as total graph-write collapses. A non-numeric `expected` (a graph implementation reporting no total, a lightweight pipeline result) does not skip the guards — it INVERTS them: `undefined < 100` is false, so the small-repo exemption never fires, and `0 >= undefined * 0.5` is `0 >= NaN`, also false, so the ratio check "passes" as well. Both bounds silently evaporate and every such run is flagged. That is precisely the failure this check was written to catch, reproduced inside the check itself: an unmeasurable quantity treated as a measured zero. Both sides are now validated as finite numbers before any comparison. `persisted` is also passed as UNKNOWN rather than zero when the DB was not demonstrably readable: `getLbugStats` flattens "no connection", "query threw" and "empty table" all into `edges: 0`, so `stats.nodes > 0` is used as independent evidence the read happened at all. Caught by the existing run-analyze suites, not by the new unit tests — those exercised the pure function with well-formed numbers and were blind to the integration's actual inputs. Both cases are now pinned. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(typescript): make object-type aliases own their members A TS object-type alias declares the same `property_signature` members as the interface beside it and answers the same question, but was not a member owner: its fields were minted with bare ids and no owner edge, so two aliases in one file sharing a field name collapsed onto one node, while the identical interface resolved normally. `type_alias_declaration` joins CLASS_CONTAINER_TYPES (and CONTAINER_TYPE_TO_LABEL, as that set's invariant requires — a container missing there gets orphaned member edges or a wrong owner label). Aliases with no object type (`type Id = string`) declare no members, so they own nothing and are unaffected. This also lands the INTERFACE field -> consumer edges, verified on the mini-repo fixture rather than only on a purpose-built one: `saveToDb` now links to `ValidationResult.value`, and `formatLogEntry` to `LogEntry.level` and `LogEntry.message` — three real contract-field reads that previously had no graph path at all. Golden updated: +3 ACCESSES, no node changes. The ALIAS field -> consumer edge is still not linked and is recorded as a todo with the exact blocker: resolving a receiver typed as the alias needs the NAME to resolve to a class-like def, and `isClassLike` is Class|Interface|Struct|Record|Enum|Trait. That predicate is read from ~12 sites including MRO and heritage, and every language mints TypeAlias, so widening it would enrol aliases in linearizations where they do not belong. Widening only the scope index was tried and reverted — the type-name walkers gate on it independently, so it fixed nothing and left dead code. That needs a deliberate "shape-like" concept, not more call-site widening. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(test): record the traced diagnosis for the unlinked alias field edge Traced to the end rather than left as "needs investigation", so the next attempt starts from facts: 1. Graph side is COMPLETE and symmetric with the interface — Property:...:LiveModeConfig.bookSlots is owner-qualified and carries HAS_PROPERTY. 2. Resolution DOES reach resolveClassBindingForName('LiveModeConfig') (instrumented) and misses. 3. It misses because the module scope binds LiveModeIface:Interface, renderAlias, renderIface — and not LiveModeConfig. The alias has no binding on the receiver's scope chain at all. 4. The TS scope query tags aliases @declaration.type, but normalizeNodeLabel accepts only typealias / type_alias and has no "type" case, so it returns undefined. Kotlin and Dart use @declaration.type_alias; TypeScript is alone on the dead tag. 5. Retagging is NECESSARY BUT NOT SUFFICIENT — tried, and the binding still does not appear, so a second gate exists in how a declaration anchored on a node that is ALSO a @scope.class anchor is attached: the alias appears to bind inside its own scope rather than hoisting to Module, where interface_declaration evidently does hoist. An isShapeLike predicate (the nominal-vs-structural split: shapes declare members, nominal types participate in MRO) plus a mirrored findShapeBindingInScope were built and REVERTED along with the retag. With no binding on the chain they never fire, and shipping inert widening is worse than shipping none — the same standard applied to the earlier scope-index attempt. The design is recorded here; it is worth doing once step 5 is fixed, and it also unblocks Rust's parked union_item, which the MEMBER_OWNER_NODE_TYPES comment documents as the same gap in another language. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): resolve cross-file value references, skip block-locals Two halves of the same question, "who uses this constant?". CROSS-FILE. `resolveReferenceSites` runs against the registries and, as its own comment says, "imports live in finalized bindings the registries can't see" — which is why free CALLS need `emitFreeCallFallback`. Reads had no counterpart, so `import { LIMIT }` followed by a bare use resolved to nothing while a CALL through the very same import statement resolved fine. This adds the read/write counterpart, reusing `findValueBindingInScope` (which walks the FINALIZED chain) rather than inventing a lookup. Confidence 0.9: the import names the def, so this is precise resolution, not inference. BLOCK-LOCALS. Bare-identifier capture also matches a read of a block-local `const`, and an edge to one keeps alive exactly the inert locals `pruneLocalSymbols` exists to drop — a pruned node becomes a retained node plus an edge, in every function of every indexed repo. Emission now takes the set of value defs bound at MODULE scope and drops ACCESSES to Const/Variable/Static outside it. The cross-file pass carries the same guarantee structurally: a def in another file cannot be a block-local of this one, so it skips same-file hits entirely. The block-local leak was already shipped in the intra-file A2 commit and was found only because a test was written for the guard rather than the feature — the same way the object-literal id collision surfaced. Verified on the full resolver matrix: 3172 tests, golden unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(lbug): diagnose a vanished staging CSV instead of surfacing a Binder error A forced rebuild could fail with "COPY failed for File: Binder exception: No file found that matches the pattern .gitnexus/csv/file.csv" and then an ENOENT on .gitnexus/csv/rel_Folder_File.csv — two engine-level messages that name neither a cause nor a remedy, which is where several field reports end. Only tables with rows > 0 enter the COPY manifest (csv-generator.ts), so an absent file was WRITTEN during this run and removed since. Both COPY loops now preflight and say exactly that, with the row count, both causes the reports point at (a second `gitnexus analyze` on the same repo — they share .gitnexus/csv — or an external cleanup of .gitnexus/), and the action to take. Scope note, deliberately narrow: this does not attempt to fix WAL corruption or checkpoint rotation. Those already have detection and recovery hints (isWalCorruptionError, WAL_RECOVERY_SUGGESTION, the configurable wal-checkpoint-threshold), and the ~6000 lines added to lbug/ + storage/ since v1.6.9 — index-lock.ts most of all, which serializes writers and plausibly closes the concurrent-run class outright — postdate every report in the window. Guessing at unreproducible durability faults would be speculation; making the one failure with NO handling legible is not. An existing overlap test induced this exact scenario (a manifest entry pointing at a missing csv) and asserted on the engine's wording. Its intent — that a node-COPY failure is rethrown at the FK barrier rather than swallowed — is unchanged and still asserted; only the message it matches moved. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): split shape-like from class-like, linking alias fields Completes A4: a field on a TypeScript object-type alias now links to the code that reads it, the last unanswerable half of "who breaks if I remove this?" for a TS frontend that models contracts as `type X = { … }`. `isClassLike` answered two questions that only coincide for classes: 1. does this declare MEMBERS I can look up? — a SHAPE (structural) 2. does this participate in inheritance / MRO? — a NOMINAL TYPE An object-type alias is (1) and emphatically not (2) — it has no supertypes and no place in a linearization. Widening `isClassLike` to buy (1) would have enrolled every language's aliases (Rust type_item, Kotlin/Swift/Dart typealias, C typedef) into MRO and heritage, so the two questions now get two predicates. Call sites split by which they ask, and their names already said which: `resolveInheritanceBaseInScope` and `resolveQualifiedInheritanceBase` keep `isClassLike`; receiver typing and member OWNERSHIP take `isShapeLike`. Three parts, each necessary and none sufficient alone: - `findShapeBindingInScope`, mirroring `findValueBindingInScope`'s established relationship to `findClassBindingInScope` (same walker, different accepted def-type), consulted only AFTER the class lookup misses so a class of the same name always wins. - `populateClassOwnedMembers` uses it, so alias members get an `ownerId` and are registered under the alias. Without this the receiver resolved to the alias and then found no members under it. - The TS scope query tags aliases `@declaration.type_alias`, not `@declaration.type`: `normalizeNodeLabel` accepts typealias / type_alias and has no "type" case, so the old tag mapped to NO label and TypeScript aliases produced no scope-resolution def at all. Kotlin and Dart already spelled it this way; TypeScript alone was on the dead tag. An earlier attempt concluded a further "scope-attachment gate" existed. That was wrong and is worth recording: scope extraction runs in the parse WORKER, which loads built `dist`, so the retag was never executed. Rebuilt, the alias hoists to Module scope exactly as the interface does. Same trap as the parse query — `src` edits to anything the worker runs are invisible until `npm run build`. Typedef and Union stay out of `isShapeLike` deliberately: they belong conceptually (the union_item note on MEMBER_OWNER_NODE_TYPES records the same gap) but neither is wired as a member container, so including them would widen a predicate nothing exercises. Verified on the full resolver matrix: 3173 tests, golden unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(typescript): pin the type-alias capture to a tag that maps to a label The capture test asserted `@declaration.type`, the tag that `normalizeNodeLabel` does not recognize (it accepts typealias / type_alias and has no "type" case). So the test passed for as long as the tag was broken: it checked only that the capture FIRED, never that it resolved to anything, while TypeScript aliases produced no scope-resolution def at all. Updated to the working tag and given a second assertion that the derived kind string is one the label mapper accepts — the property that actually matters, and the one whose absence let a dead tag sit pinned. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(lbug): declare TypeAlias member pairs so analyze does not abort Making object-type aliases member owners emits HAS_PROPERTY from a `TypeAlias`, and the relation schema declared no such pair. The emit therefore threw `UndeclaredRelationPairError` and the ENTIRE analyze died on any repo containing `type X = { ... }` — a hard stop, not a dropped edge. Found by running the analyzer over a real 16k-node TypeScript repo, not by a test. `Method` is declared alongside `Property`: a member written `type Handler = { onClick(): void }` is a method_signature and would fail in exactly the same way. Why every existing test missed it: the resolver suites build an in-memory graph via `runPipelineFromRepo` and never write to LadybugDB, so the schema constraint was never exercised. `structural-pair-coverage.test.ts` is the one suite that does run the emitters against the declared pairs — and its own docstring names the gap: coverage is bounded by NON_BRIDGE_CORPUS, "a new structural emitter should land with an entry here". This adds that entry, pinning TypeAlias|Property and Interface|Property as sentinels. Verified the guard is not vacuous: removing the pair again makes the suite fail with undeclaredPairs: ["TypeAlias|Property"]. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(processes): trace depth-first so multi-hop flows are detected D1 ("query ranks frontend components above the backend module that owns the concept") and D2 ("processes is dominated by trivial mechanical chains") are the same defect, and neither is about ranking or selection. The walk stops after a fixed NUMBER of traces, so traversal order decides which traces those are. Breadth-first reaches every shallow terminal before any deep one, so the quota filled with the shortest paths in the graph and the walk stopped — `maxTraceDepth: 10` was never approached. Measured on a real repo before the fix: of 300 processes NONE exceeded 7 steps and 90% were 3-4. A multi-hop business flow (signal → order → exit) therefore had no process that could represent it, and `query` could only rank the mechanical pairs that did exist. Step 4 of the caller already sorts by length and dedupes by endpoint — it was always asking for the deepest traces this walk could give it. Depth-first descends to a terminal first, so the same quota is spent on paths worth keeping. Cost is unchanged: same budget, same cycle guard, same depth ceiling — only the order differs. Measured on the same 16k-node repo, same build and flags, BFS vs DFS (an earlier comparison was discarded as confounded — it crossed builds and --pdg): steps 6-8: 50 → 168 (3.4x) totals: 844 → 806 and the reported query moved from `LiveSetupView → Cn` (a React component) to `ReconcilePositions → IsTpInProfit / WithHeld / ShouldNotify` — server-side exit management, which is what was asked for. `traceFromEntryPoint` is exported for the test. Traversal order is unobservable through `processProcesses`: `findEntryPoints` supplies several starting points, so a deep chain is traced from inside it whatever the order does. A test at that level passes under BOTH traversals — the first version of this test did exactly that and guarded nothing. Driving the walk directly, it fails under breadth-first with "expected 3 to be greater than 3". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(test): correct a stale status note left behind by a later fix The A1/A5 header still said "edge resolution REMAINING ... neither is implemented". Both shapes resolve — the typeable receiver precisely, the untyped one by workspace-unique name — and the tests below assert exactly that, so the note contradicted the file it sat on. It was accurate when written and went stale when the work continued past it. Left as-is it would tell a reviewer that a landed feature is missing. The TRAP note is kept: the parse worker still runs built dist under vitest, and that is still the trap it describes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): index literals behind identity-preserving wrappers `export const INERT_EXIT_CONTRACT = Object.freeze({ ... })` minted no `Property` node for any of its keys. The object-literal rule matches `variable_declarator > value: (object)` as a DIRECT child, and freezing puts a call expression in between — so the shape whose fields are most worth querying was the one shape the rule could not see. Freezing a config object is how JS publishes an immutable contract, which is why this reads as a confident zero on exactly the fields a reader cares about. The allowlist is three functions, not "any call". `Object.freeze`, `seal` and `preventExtensions` RETURN THE ARGUMENT THEY WERE GIVEN, which is what makes the literal's keys members of the bound name. For `const x = compute({ a: 1 })` the literal is an argument and `x` holds compute's return value, so attributing `a` to `x` would be a fabrication. Two negative controls, because the obvious one is vacuous: a bare-identifier callee is rejected structurally and would pass with no allowlist at all, so the assertion that actually pins the predicate uses `Object.entries` — identical shape, differing only by name. Verified load-bearing by adding `entries` to the allowlist and watching that test alone fail. SCHEMA_BUMP 46 -> 47: parse-time emission, so a warm cache replays the pre-fix capture set. Observed as a false negative first — `analyze --force` returned the old node set until the on-disk cache was removed by hand. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): narrow multi-candidate property names by scope Workspace uniqueness was the wrong denominator. Measured on the reporting repo: `exitMinAtrMult` has 26 `Property` definitions — 16 in one-off `scripts/`, 7 in the frontend, one in a test, and exactly ONE in the backend that reads it. Every backend read was refused because of competitors the reader cannot see. The gate was not too permissive or too strict, it was scope-blind. A name with several definitions is now narrowed before being abandoned: same-file first, then files the reading file directly imports, using the finalized import graph rather than a path-shape heuristic. Exactly one survivor at the first non-empty tier resolves; anything else stays refused. A tier holding several candidates stops the walk instead of falling through — local evidence that is itself ambiguous still contradicts reaching further out. Confidence stays 0.5 at every tier. Narrowing changes which candidate is chosen, not the kind of claim: it is still a name match, and the round-1 contract is that filtering on confidence drops all name inference at once. The reason string now names the tier that fired. Ambiguity reporting goes from a count to the actual names (capped), because a count says a gap exists while the names say which fields are unanswerable. Measured on that repo, backend readers of `exitMinAtrMult` go 0 -> 24 and total readers 9 -> 45, including the two call sites in `oppositeSignalExitManager.js` the report singled out. Both narrowing tests were mutation-checked by dropping the import evidence and confirming they, and only they, fail. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): capture destructured parameter keys as property reads `function exit({ exitMinAtrMult = 0 })` reads that property off whatever the caller passes, exactly as `cfg.exitMinAtrMult` would. It never appears in a member_expression, so it had no reference site at all — and this is the shape the function that IMPLEMENTS a behaviour uses, so the most relevant reader was the one systematically missing from "who reads this setting?". Uses a distinct `@reference.read.destructured` anchor rather than `@reference.read.member`. The latter is filtered emit-side to matches with a member_expression ancestor, because calls and writes share its shape, and a destructuring pattern has none — reusing the tag would have been silently dropped by that filter. The `read.` head already maps to a read kind, so no mapping change is needed. Scoped to formal_parameters. A destructuring binding elsewhere (`const { x } = require('m')`) is frequently an import rather than a field read, and minting a property read there would attribute module bindings to unrelated same-named keys. All three cases (default value, bare shorthand, renamed key) mutation-checked by removing the patterns and confirming those three tests, and only those, fail. The renamed case also asserts the edge points at the KEY and that the local alias mints nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): link type consumers to the type they name An exported contract type owned its members after round 1 and still answered `incoming: {}`, so "what breaks if I remove this field?" — the question a contract type exists to answer — had no edge to walk. Measured on the reporting repo: all 324 TypeAlias nodes AND every Interface node had DEFINES as their only incoming edge. Two independent causes, and the second is why the first was not enough. TypeScript captured no type references at all — only cpp and csharp did — so an annotation naming a declared type minted no reference site. Added for annotations, generic arguments and `as` assertions, anchored to those contexts rather than a bare `(type_identifier)`, which would also match the name in `type X = …` and make every declaration a consumer of itself. That alone fixed interfaces and left aliases still empty. `TypeAlias` was missing from `LINKABLE_LABELS`, so alias graph nodes were never indexed in `nodeLookup` and `resolveDefGraphId` could not bridge a def to its node — the edge was dropped AFTER a successful lookup. `CLASS_KINDS` has always listed TypeAlias and the ClassRegistry returned the def correctly, which is what made this read as a resolution failure; instrumenting the lookup showed it returning the right def all along and moved the search one table over. Exactly the bug already documented two entries above it for Trait. Fixes every language that spells an alias this way — TypeScript, Kotlin, Dart and Rust all emit `@declaration.type_alias`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): capture record construction as property writes The read side answered well after the narrowing work while "who SETS this field?" still missed the code that stamps the value. A record built inline — `return { exitContract: { exitMinAtrMult: settings.x } }` — is bound to no variable, so it minted no definition and its keys referenced nothing. Modelled as WRITE REFERENCES, deliberately not definitions. The round-1 rule already mints Property nodes for literals bound to a variable; minting more for anonymous records would add same-named competitors to the very name-narrowing that makes these fields resolvable — measured at 26 competing definitions for one field on the reporting repo, which is what made every backend read unanswerable in the first place. A construction site is a USE of a field, not another declaration of it. Two positions only: nested under a key, and returned. Both are records with a name attached (the key, or the function). An inline call argument (`doThing({ id: 1 })`) stays excluded for the same reason round 1 excluded it from definitions — it is call-site data, not a named surface — and is asserted as such. The enclosing literal is the receiver and it is anonymous, so these route through the same narrowing and the same refusal-to-guess as every other untyped receiver. Verified on the reporting repo: `entryPlan.js` went from no rows to `selectExitEnvelope` as a writer of `exitMinAtrMult`. Both captures mutation-checked. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(processes): select round-robin by terminal so the list is not one flow repeated Ranking was `sort by length` alone, so the top of the list was one behaviour described many ways: eleven of the top fourteen processes on the reporting repo were four entry points crossed with three terminals of the SAME date-window utility cluster. Genuine call chains, but a reader learns one thing from fourteen entries, and the repo's own domain flows sat below them. Selection now round-robins across TERMINALS, deepest first. Depth still orders within a terminal and still leads the list; what changes is that no terminal takes a second slot until every other has had a first. Keying on the entry point was tried first and made it worse — many files declare a `main`, so each was a distinct entry that round-robin then awarded its own slot, and `Main -> AlignWindowEnd` went from one row to eight. The repetition was never in where a flow starts. Measured on that repo: distinct terminals in the top 20 went 3 -> 20, and its domain flows (`ReconcilePositions -> ...`) moved into the top 4%. Two things this deliberately does not claim. The reported cause — ranking rewarding fan-in, promoting chains ending in widely-called helpers — measured FALSE: those terminals have one caller each (`alignWindowStart` 1, `validateSymbol` 1). A fan-in discount was implemented against that hypothesis, measured, and reverted for moving nothing. And a business flow still cannot be a process in its own right: the walk only emits at a leaf, at max depth, or on a cycle, so a flow whose meaningful endpoint calls onward survives only as whatever leaf it bottoms out in. Both are recorded in the code so neither reads as settled. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(structural-pairs): pin the type-annotation USES pair R2-2 emits USES INTO a `TypeAlias`, so the pair is `Function|TypeAlias` — a different table from the `TypeAlias|Property` entry added in round 1, and one that entry stays green without. `TypeAlias` is on the eleven-table list this suite exists for, and an undeclared pair does not degrade: it throws `UndeclaredRelationPairError` and kills the entire analyze on any repo containing an annotated type. Every resolver suite still passes, because they build an in-memory graph and never write to the DB. That exact failure shipped once in this PR already. Two emitters into the same label, each with its own way to reach a released build. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): build the module-level set before the out-of-core seal Review blocker. Under `GITNEXUS_DISK_SCOPE_INDEX=1` the seal replaces every ParsedFile with a scope-STRIPPED copy, and the block-local filter's set was built after it — so it walked `scopes: []` for every file, came out empty, and the filter read that as "no def is module-level" and dropped EVERY `Const`/`Variable`/`Static` ACCESSES edge in the repo. All languages, all files, including the module-scope-const edges this PR exists to add. Nothing threw and nothing logged, on the path the largest repos take: the exact confident-empty answer the PR is about. Built above the seal now, from `parsedFiles`, and passed as `undefined` rather than an empty set when no scope was inspectable — an empty set is a legitimate answer ("this repo has no module-level value defs") and must not be indistinguishable from "could not look". Fails open; the block-local exclusion is still asserted under the seal, since that is correctness rather than optimization. Also widens module level past `kind === 'Module'`. A `Namespace` scope (TS `namespace`, Rust `mod`, C++/C# `namespace`) holds importable values too, and treating its consts as function-locals dropped their reads. Included only when the whole chain to the root is Module/Namespace, so a namespace declared inside a function body stays local — asserted both ways. That fixture then failed for a third reason: `@reference.read.identifier` existed ONLY in the JavaScript query, so A2 did not work for TypeScript at all. Added there, and both languages widened to `variable_declarator value:` and `binary_expression` operands — the gaps review named between what A2 claimed and what it matched. Nothing covered `GITNEXUS_DISK_SCOPE_INDEX`. The new parity test asserts the seal changes no edge, and was verified against an emulation of the original bug: same-file readers vanish and only the cross-file reader survives. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(typescript): anchor property_signature to declared shapes Review blocker, and it reproduces end to end. `property_signature` occurs in EVERY object_type in the TS grammar, not only in an interface body or an alias's object type, so inline parameter types, inline return types and nested object types all matched — and the enclosing-container walk hung each one off the nearest class, interface or alias. Measured against the unanchored rule, all four appeared as members of shapes that do not have them: Property:contracts.ts:Svc.inlineParamOnlyKey Property:contracts.ts:Repo.inlineQueryOnlyKey Property:contracts.ts:NestedConfig.nestedOnlyKey Property:contracts.ts:buildInline.inlineReturnOnlyKey@46:33 When the inline member shares a name with a real one — `run(opts: { retries: number })` inside a class that declares `retries` — `addNode` is first-write-wins and the two distinct symbols merge onto one node, so every context()/impact()/rename() answer about that field describes the merge. The sibling JS object-literal rule in this same PR is anchored for exactly this reason; this is the TypeScript half of the same fix. `(A (B))` matches DIRECT children, so nested object types are excluded by the same anchor rather than by a second rule. The first version of these tests was VACUOUS and is recorded here because the reason generalizes: a collision and a correct exclusion both leave exactly one node behind, so counting ids cannot distinguish them. Every inline member in the fixture is now uniquely named, which is the only thing that discriminates — verified by restoring the unanchored rule and watching exactly those four assertions fail. A fifth test asserts anchoring costs no real member. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(analyze): correct the numbers feeding the graph-write-collapse guard Review blocker. The predicate itself held under adversarial probing; every defect was in what it was handed and what happened after it fired. (a) `expected` was wrong twice. Under `GraphEmitSink` streaming the bulk types leave the heap at parse time and never enter `relationshipCount`, so the count understated the real volume by most of it and the ratio passed trivially — on `force === true` runs, which include crash recovery AND the `analyze --force` retry this check's own warning tells the operator to run. Adds the manifest totals, the same correction the buffer-pool hint in this file already makes for the same reason. Separately, an incremental run persists only the changed subgraph while both counts are whole-scope: a 10,000-edge index that lost 200 replacements reads 9,800 and is certified complete. The check is skipped on that path rather than answered wrongly. (b) A throwing edge count became a measured zero. `getLbugStats` initialised its total to 0 and ran the query in a swallowing catch, so WAL/lock contention during finalize — documented on this exact call — reported a healthy index as a total collapse. It now returns `number | undefined`, and the caller requires both a readable node count and a defined edge count. (c) A total loss was exempted for being small. The min-edges rule tested `expected` before looking at `persisted` at all, so `expected = 99, persisted = 0` — every edge gone — stayed fresh and reported success. Total loss is now decided first. The existing test asserted the defect; it now asserts a PARTIAL shortfall, which is the case the exemption was written for. (d) A detected collapse reported success and exited 0. It is different in kind from the other incomplete reasons: those describe a run that did what it said and left work for later, this one means most of your edges are gone and every query answers a confident empty. The CLI now prints INCOMPLETE with the counts and sets a non-zero exit code, and the flag crosses IPC so the worker cannot send a clean `complete` either. Nothing exercised this wiring — only the pure helper. Adds tests for all four, each written so the pre-fix arithmetic fails it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): keep unique-name property inference inside one language The pass indexed `Property` nodes from the whole shared graph. Per-language gating decides whether it RUNS for a language; it never restricted which nodes could be TARGETS. So the only carrier of a name could be in another language entirely, and a read here resolved to it on name uniqueness alone — no owner, no file, no call path. Reproduced: a Java class declaring `private int loyaltyPointsBalance` and a JS `cfg.loyaltyPointsBalance` on an untyped parameter produced an ACCESSES edge from the JS function to the Java private field. Confidence does not mitigate it, because `minConfidence` defaults to 0 — the tier is only a filter for consumers who ask for one. Candidates are now restricted to files in the language's own `parsedFiles`, which is a precise restriction rather than a heuristic and needs no new node property. Every other fixture in the suite is single-language, so this could not be caught anywhere by construction. The new fixture is deliberately polyglot and asserts both halves: no cross-language edge, and a same-language unique name still resolves. Known and not addressed here: the index is still O(total graph nodes) and is rebuilt once per qualifying language, the per-language whole-graph-scan pattern `phase.ts` hoisted out for `sharedNodeLookup`. Hoisting it belongs with that machinery rather than in this fix. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(processes): explore siblings in source order, log the exhausted budget `slice(0, maxBranching)` selected the FIRST N callees while `pop()` explored them LAST-first, so the trace budget went to the last-declared branch. For `main() { init(); loadConfig(); run(); shutdown(); }` the walk spends itself on `shutdown` and can drop `init` — the earliest steps of a flow, which is the opposite of what a process describes. Selecting first-N and exploring last-first was simply inconsistent; pushing in reverse makes the stack pop in source order. Measured on the reporting repo, this costs depth: 6-8 step processes go 168 -> 146 of 816. Still roughly three times the pre-PR baseline of 50, and the right trade — a deep branch is no longer reached by accident of being declared last. The remaining limit is the BUDGET, not the traversal: with a fixed quota a deep branch declared after enough shallow ones is not reached at all. That is now asserted in both directions rather than left implicit, and the walk logs when it stops with branches unexplored — a silently truncating cap reads as "this is everything", the same confident-empty answer this work is about, and the repo already sets that precedent for `dispatchFanoutSkipped`. Removes the second depth test, which was vacuous: the note twelve lines above it already said a `processProcesses`-level depth assertion passes under BOTH traversals, and measured it does — breadth-first yields the same deepest stepCount of 8, so it passed with the production change reverted. Traversal order is asserted against `traceFromEntryPoint` directly; what is observable at the pipeline level is which traces survive selection, which the diversity tests cover. Also renames `queue` to `stack` and corrects the BFS references in the module docstring and the function's own JSDoc, which is what an IDE hover shows. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(impact): carry riskNote onto ambiguous candidates and separate UNKNOWN's two meanings Two problems on the ambiguous fan-out, which builds its own candidate object rather than returning the single-symbol shape. The narrowed type had no `riskNote` field and never read one, so a candidate that resolved and found no callers reported `risk: UNKNOWN` with nothing attached — losing the entire point of the change on the path where the reader has the least context, since the name is ambiguous there by definition. And `UNKNOWN` used to mean exactly one thing on this path: the probe threw. The zero-caller branch gives it a second meaning, so an all-UNKNOWN fan-out could no longer be told apart from a broken one. Candidates now carry `probeFailed`, and the comment asserting the old reading is corrected. Also aligns `gitnexus-web`, which review flagged as giving a different verdict for the same symbol. That surface answers in prose rather than an enum, and its message said the symbol "appears to be unused (not called by anything)" — the identical false certainty in words. It now carries the same MEANING rather than the same field. Downstream wording is unchanged: no outgoing dependencies really is a fact about the symbol itself. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test: replace assertions that cannot fail Four from review, each satisfied by the defect it was meant to catch. `new Set(props).size === 2` over two different literal strings can only ever be 2, so it could not detect the node merge its title promises — that is a difference in COUNT, now asserted on the raw array. The ambiguity test asserted only an empty edge set, which is satisfied equally by "the gate fired" and "the name was never looked up". It now also requires the ambiguity counter to have moved. `Interface|Property` was listed as a structural-pair sentinel beside `TypeAlias|Property`, but both its labels are in the SCOPE_BRIDGE cross-product so the pair is generated by construction and the sentinel cannot fail. Dropped rather than left reading as coverage; `TypeAlias|Property` is the load-bearing one. `TypeAlias|Method` was declared in the schema with no fixture emitting it — a declared pair no emitter exercises is indistinguishable from a missing one until an analyze aborts on a real repo. Adds a method-shaped alias member, and the suite requires sentinels to actually appear, so it is not vacuous. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs: document the new incomplete reason, the UNKNOWN verdict and the id churn Review found the code changes landed without the guidance around them, and an agent following this repo's own rules would have been told the wrong thing. `graph-write-collapsed` joined `INDEX_INCOMPLETE_REASONS` with no Sign block and no recovery section, while the precedent it cites (`embedding-checkpoint-pending`) has both — so `gitnexus status` would surface a new string naming silent wrong answers with nothing explaining trigger or remedy. Added to RUNBOOK and GUARDRAILS, including why this reason alone also fails the exit code. `AGENTS.md` said MUST warn on HIGH or CRITICAL and never mentioned UNKNOWN, and the shipped impact skill's risk table had no UNKNOWN row and still implied few-callers ⇒ LOW. An agent obeying those rules literally sees `risk: UNKNOWN` and proceeds, which negates the change the verdict exists to make. Both copies of both skills updated. `MIGRATION.md` now records that process ids do not survive this release — positional ids plus depth-first tracing, source-order siblings and round-robin selection mean `proc_7_handle` is a different flow afterwards. Bounded honestly: nothing in-repo joins on a raw process id, so it is index churn, not a broken consumer. `ARCHITECTURE.md`'s scope-resolution stage list gains the two new stages. The guide skill's node list gains `Property` and `TypeAlias` — the two node types this work most prominently creates. Also, on the pair-CSV preflight review asked to confirm: the hard abort IS deliberate, because a fallback recovering zero rows is the confident-empty failure this work targets. But the transient the message itself names — a second concurrent analyze sharing `.gitnexus/csv` — is a race, so the check now re-looks three times over ~150ms before declaring the file gone. Long enough to ride out a rename, far too short to mask a file that is genuinely missing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix: drop redundant TypeAlias pairs and keep bare identifiers off class members Two regressions the full suite caught after the review fixes, both real. `schema-pair-coverage` failed with eleven hand-declared pairs that a rule now generates. Adding `TypeAlias` to `LINKABLE_LABELS` — needed so `resolveDefGraphId` can bridge an alias def to its node — also makes it a SCOPE_BRIDGE source and target, so the cross-product produces `File|TypeAlias`, `TypeAlias|Property` and nine others that round 1 had declared by hand. Removed; the invariant is that no pair is both generated and hand-declared. This also changes what the structural-pair sentinel means, and the comment is corrected rather than left overstating it: `TypeAlias|Property` is no longer load-bearing because the label is off the generated grid — it is load-bearing because it now depends on `TypeAlias` being IN `LINKABLE_LABELS`. Remove it and the pair stops being generated while the hand declaration is gone, which is the same state that silently breaks alias consumer edges. `block-scope-shadowing` failed because a bare identifier resolved to a class `Property`. `class Box { baseUrl = '...'; pick() { const baseUrl = ...; return baseUrl; } }` linked the block-local read to `Box.baseUrl`, duplicating the legitimate `this.baseUrl` edge. A bare identifier is not a member access: with no receiver there is no object whose property it could be, and in JS/TS a field read needs `this.`. Receiver-less read/write sites no longer accept `Property` hits; callables stay reachable, so `cb = save` naming a top-level function is unaffected. That defect PREDATES this branch's TypeScript captures — JavaScript has emitted bare-identifier reads since A2 and no class fixture exercised the shadow. The TS parity added here is what surfaced it. Golden snapshot regenerated after verifying the drift line by line: exactly +5 USES from type annotations in the mini-repo, every pre-existing count unchanged, so nothing was rewired. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * perf(scope-resolution): share the property-name index across language passes Review follow-up. `indexPropertyNodesByName` scanned every node in the graph and was rebuilt inside each qualifying language pass, reintroducing exactly the pattern `phase.ts` hoisted out for `sharedNodeLookup` — whose comment records why it matters: "the previous per-language rebuild burned that CPU+heap N times and, on a huge repo, a tiny language's full-graph copy overlapped the next language's — a real contributor to the scope-resolution memory peak." Built once in `phase.ts` beside `sharedNodeLookup` and `sharedFnNodeIndex`, and threaded through the same `prebuilt*` seam, so tests and isolated calls still build their own. Sharing is only safe because the per-language restriction MOVED rather than disappeared: the shared index is whole-graph, and candidates are filtered to the language's own files at lookup time. That also fixes a subtlety the per-language build had backwards — the cap now applies to the FILTERED set, so a name carried by forty properties across a polyglot monorepo but only two in the language being resolved is still answerable, where a global cap would have refused it. The tri-state at the lookup boundary is deliberate and the three outcomes are not interchangeable: no property of this name in this language (nothing to say, and NOT an ambiguity), too many to choose between (reportable), or a list to narrow. Caught mid-change by the polyglot fixture: an intermediate state shared the index without moving the filter, and the cross-language edge came straight back. That test earning its keep twice is the reason it exists. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): report when a field's only anchor is another language Round 3, found OUT-OF-SAMPLE — six field names appearing in no prior report, so nothing here was tuned against them. All six answered 0 backend ACCESSES while their definitions sat in `apps/research-dashboard/**`: TypeScript only. The in-sample set scored 5/5 and the out-of-sample set 0/6, and the gap is entirely this. Per-language inference (`3c5eadc7`) is right and stays. What was wrong is that declining is INVISIBLE: an empty result for a field anchored only in TypeScript is byte-identical to an empty result for a field nobody reads. One says "look in the other language or grep"; the other says "delete it". That is the same confident-empty failure this series exists to remove, one surface over — and this time the missing fact is about the ANALYZER's reach rather than the code. Declines are now counted and named, with the languages the anchors actually live in, kept SEPARATE from ambiguity because the remedies differ: ambiguity wants better receiver typing, this wants an anchor in the reading language. Collapsing them would tell a reader the wrong thing to do. A non-zero count warns at analyze time regardless of dev mode. The facts are published as `PipelineResult.propertyInference`, which they had to be for any of this to be testable — and that exposed a second defect. The round-2 ambiguity assertion, which I told the reviewer of #2856 I had strengthened, read its stat off a `scopeResolution` field that does not exist on PipelineResult: the `if (undefined) return` guard swallowed it and the test passed with the production code deleted. Both that assertion and the new ones now read the published field, and the guard is an assertion rather than an escape. Verified by deleting the counter and watching them fail. Reported by the same round-3 method note that caught it: verifying a fix against the cases it was written for only proves those cases pass. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(context): explain an empty property result caused by a cross-language anchor The other half of R3-1. The analyze pass now knows which fields it declined to link because every definition of the name lives in another language; this puts that fact where it is actually read. `context()` on such a field previously returned an incoming list byte-identical to a genuinely unread field. The two demand opposite actions — "look in the other language, or grep" versus "delete it" — so the difference has to travel with the answer: unresolved: property reads of this name were NOT linked: every definition of it is typescript, and name inference does not cross languages. An empty or short incoming list here is not evidence the field is unused — confirm with a text search, or give it an anchor in the reading language. anchorLanguages: ['typescript'] Carried through repo meta because the graph cannot answer it: the unlinked reads mint no edge and no node, so the only record is the pass that declined them. Keyed on the NAME, not on the resolved label. Gating on `=== 'Property'` was tried first and is wrong — the label reads `''` on this path for a plain Property node, so the gate silently suppressed the entire feature while every test still passed. Caught by asserting the field is DEFINED rather than guarding on it, which is the same anti-pattern that made two earlier assertions vacuous. The meta list only ever contains property names, so matching the name is itself the type check. Cached per (index, indexedAt): `ensureInitialized` deliberately avoids a per-call `loadMeta` because every tool routes through it, so this re-reads exactly when a re-analyze could have changed the answer and never otherwise. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): report declined property reads for opt-out languages too Generalizing R3-1 rather than waiting for it to be re-reported in the other direction. The reported case was a JavaScript read whose only anchor was TypeScript; the mirror — a TypeScript read anchored only in JavaScript — was still silent, because a language that sets `fieldFallbackOnMethodLookup: false` had the whole pass skipped, and skipping emission also skipped REPORTING. Detection is not inference. Counting what could not be linked asserts nothing about what it means, so `reportOnly` runs the pass for its facts while emitting no edge, and the opt-out keeps protecting exactly what it protected before. Two things this turned up that a single-instance fix would have missed: The cross-language fixture could NOT prove `reportOnly` is load-bearing — the per-language candidate filter already blocks those edges, so the assertion passed with the flag forced off. The case that discriminates is a SAME-language TypeScript read that name inference could legitimately link and the opt-out forbids; forcing the flag off there emits `readsTsOnly -> tsOnlyBudget`, which is the violation. Getting to that case surfaced a sibling gap, recorded but NOT fixed here: the object-literal `Property` rule is JavaScript-only, so `const CONFIG = { ... }` in a `.ts` file mints no node and its keys are invisible. The first draft of this fixture used exactly that shape and could not discriminate for that reason. It is the TypeScript half of R2-1a and wants its own change, not a rider on this one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(typescript): index object-literal keys, as JavaScript already did The sibling recorded in `0c5a4f64` and deliberately left out of it. Both the named object-literal rule (A1/A5) and the identity-wrapper rule (R2-1a) lived only in JAVASCRIPT_QUERIES, so the single most common config idiom in TypeScript — export const tsRuntimeConfig = { tsConfigRetries: 3 }; — minted no node for any key. `context()` answered "Symbol not found" and a precise read through the holding variable had nothing to resolve to. TypeScript sets `fieldFallbackOnMethodLookup: false`, so these gain no name-based inference. What they gain is the PRECISE path, which is the route TypeScript is meant to use: `tsRuntimeConfig.tsConfigRetries` has a typeable receiver and now resolves. A read through an untyped receiver stays unresolved and, since `0c5a4f64`, is reported as such rather than answering an empty set. Scoped exactly as the JavaScript rules are — bound to a variable, and for the wrapper only the three functions that return the argument they were given — with the same `Object.entries` negative control pinning the allowlist. Found by fixture, not by report: the first draft of the `reportOnly` test used a TS `const CONFIG = { ... }` as its discriminator and could not discriminate, because the shape mints nothing. That is the whole argument for sweeping a class instead of waiting for each instance to be filed. SCHEMA_BUMP 47 -> 48: parse-time, so a warm cache replays ParsedFiles carrying none of these matches and the keys stay invisible. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): anchor anonymous returned object literals to their function The last gap round 3 named, and the dominant shape in idiomatic JS: 437 `return {` sites in a single backend directory of the reporting repo, including the ~25-field payload of its entire signal pipeline. The literal binds to nothing, so its keys could not even be named — "who reads wickRatio?" had no symbol to ask about. The enclosing FUNCTION is the owner: the literal is that function's return shape, a contract its callers consume. Keys qualify as `<function>.<key>`, so two functions returning the same name stay two shapes rather than one merged symbol, and multiple returns in one function stay distinct by position. RECONCILING THIS WITH R2-1b, which deliberately modelled returned keys as WRITES to avoid adding same-named competitors to narrowing. These are definitions, but narrowing now ranks DECLARED anchors — named literals, class fields, interface and alias members — strictly above return shapes. A name that already resolved keeps resolving to what it resolved to before, so the competitor problem R2-1b was avoiding cannot come back. Mutation-checked: dropping that ranking breaks five pre-existing R2 resolutions. That also required an R2-1b assertion to change, and the change is a strengthening rather than a concession. It asserted `toHaveLength(1)` — no new definition — as a proxy for "adding definitions must not move an existing answer". The proxy is now false while the property still holds, so the property itself is asserted directly. No `HAS_PROPERTY` edge from the function: that would be a `Function|Property` relation pair the schema does not declare, and an undeclared pair does not degrade — it throws and kills the whole analyze. That already shipped once in this PR. Two things found by dumping rather than assuming, both fixed here: SHORTHAND keys were not matched at all. `return { symbol, interval, score }` is the commonest spelling and the reporting repo's own payload is mostly this form, but tree-sitter models it as `shorthand_property_identifier`, which `(pair)` does not match. Caught by dumping the golden fixture and seeing a literal returning `{ level, message, timestamp: Date.now() }` had indexed only `timestamp`. Now covered in return position AND in the variable-bound rule, which had the same gap. Provenance was flagged by owner-presence, which mislabelled the anonymous case: a callback's return shape yields no name to qualify by, so it looked like a DECLARED anchor and would have outranked real declarations. Flagged by position now — a different question from whether a name could be derived. SCHEMA_BUMP 48 -> 49. Within one PR the version only has to differ from main's, but a build stamped 48 was installed and used to analyze before these captures existed, so caches stamped 48 carry none of them — the intermediate-build hazard this ledger already records for 33/34. Golden regenerated after verifying the drift: exactly +10 Property and +10 DEFINES, every pre-existing count unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): rank production anchors above test fixtures Found by testing R3-4 on the reporting repo instead of on its fixtures. Anchoring returned literals took `wickRatio` from 6 definitions to 13 — and backend reads still resolved to nothing, because SEVEN of the new JavaScript anchors compete and four of them are in `tests/`. A test constructs throwaway shapes carrying production field names; a read in shipped code cannot mean one of them. Applied before the declared/return-shape split, because "is this the shipped program" is the stronger signal — a declaration inside a test fixture is still a test fixture. Skipped when the READER is itself a test, since a read there legitimately means the test's own shape. The first version of this test was vacuous and the mutation check caught it: the reader sat in the same file as the production anchor, so the same-file tier resolved it whether or not this tier existed. The reader now lives in a file that imports neither anchor, which leaves production-vs-test as the only thing that can decide. Honest about what this does NOT do: it narrows `wickRatio` from seven candidates to three, and three functions in different files each returning that field is GENUINELY ambiguous — refusing is correct, and the ambiguity is now counted and named rather than silent. The reported question ("who reads wickRatio?") is answerable only where one producer exists; where several do, the honest answer is the list of producers, which R3-4 made nameable for the first time. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): resolve members through a call result's return shape The question three rounds of reports could not answer, and the one narrowing must refuse by design: a field produced by SEVERAL functions. A read of `spike.wickRatio` could mean any producer, so name inference correctly declines and no amount of tier-tuning changes that. It needs evidence, not inference. The evidence existed in two halves that had never been joined. The call-result type binding (`const alert = formatSpikeAlert(row)` binds `alert` to a TypeRef whose rawName is the callee) predates all of this work; it simply had nothing to resolve to when the callee returned an anonymous literal, because an anonymous literal named nothing. R3-4 gave it a name. Joining them: const alert = formatSpikeAlert(row); alert.wickRatio -> Property:...:formatSpikeAlert.wickRatio Precise, at ordinary emission confidence, and it works EXACTLY where narrowing cannot: several producers sharing a field name stop being competitors because the receiver says which one. Runs before the name fallback and claims its sites, so a precise answer is never second-guessed by a name match. Measured on the reporting repo: 1,410 precise edges, and all six fields round 3 verified OUT-OF-SAMPLE go from 0 backend readers to 7, 11, 10, 7, 6 and 14. Round 3 scored 0/6 on that set; this is 6/6. The bound is asserted, not just documented: a read off a BARE PARAMETER has no binding here, because typing it needs the caller's type to flow in — that is inter-procedural and genuinely larger. Those reads still fall through to name inference and are still reported when it declines. The fixture has two producers sharing a field name precisely so the test cannot pass by name matching, and mutation-checking the owner lookup fails it. No SCHEMA_BUMP: this is scope resolution, not parse-time capture, so a warm cache already carries everything it reads. Noted in the ledger because the reflex on this branch has been to bump, and an unnecessary bump costs every user a full re-parse. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Revert "return-shape anchoring" (R3-4/R3-5): it degrades query Reverts af5eec5c, c764847a and 4f93f32e. The capability was real and measured — all six fields round 3 verified OUT-OF-SAMPLE went from 0 backend readers to 7/11/10/7/6/14, 0/6 to 6/6, via 1,410 precise return-shape edges. It is reverted anyway, because it costs more than it buys in its current form. `cli-limit-e2e` caught it. Bisected to af5eec5c: on the mini-repo fixture, `query('message')` returned two processes before and NONE after. The mechanism is not window displacement — that hypothesis was tested with a partition that kept function-local property keys from taking window slots, and it changed nothing. Indexing the keys of every returned literal adds many nodes whose names are ordinary words, which moves the BM25 CORPUS statistics: "message" gets less discriminating, and `createLogEntry` — the callable that actually carries the processes — stops ranking at all. A corpus-level effect is not repairable by a tie-break. Trading a regression in `query`, one of the core tools, for coverage in `context` is the wrong trade, and shipping it because the number was good would be the same mistake this PR spent three rounds removing: a confident answer that is worse than the honest one. What the work established, and what re-landing needs: - The mechanism is right. Joining the existing call-result type binding to a named return shape resolves `alert.wickRatio` by EVIDENCE, which is why it succeeds exactly where name inference must refuse. - The cost is search dilution, and it needs to be measured on BM25 ranking BEFORE the capture lands — not discovered by a downstream e2e test. - The likely shape of the fix is keeping return-shape keys out of the text search corpus while keeping them in the graph, which needs persisted provenance rather than the in-memory flag used here. Kept: everything through 8972d223, which is verified green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(search): give the index a notion of DETAIL symbols, and re-land R3-4/R3-5 Reverts the revert. The return-shape work was correct and measured — 1,410 precise edges, and all six fields round 3 verified out-of-sample going 0/6 to 6/6 — and it was dropped for a regression that was really a MISSING LAYER: the search index had no way to say "this symbol is queryable but is not a concept a text search should surface on its own". Indexing the keys of anonymous returned literals adds many nodes whose names are ordinary words (`message`, `value`, `timestamp`). Without that notion they compete on equal terms in FTS, push the CALLABLES named after the same concept past the search's row cap, and `query('message')` returned two processes before and none after. The layer, rather than a workaround: - `Property.isDetail`, persisted. A Property-only column, which that table already precedents with `declaredType`, set where the key is minted. - `buildFtsQueryCypher` filters on it for the Property table, BEFORE the row cap. That placement is the whole point: rows crowded out never reach the caller, so no downstream re-ranking can recover them. Two downstream fixes were tried first — a tie-break and a partition of the merge window — and recovered nothing, which is what located the real seam. - `IS NULL`-tolerant, so an index written before the column existed still answers instead of returning nothing. Verified by the A/B that found the regression: the query's result order is now byte-identical to the pre-R3-4 baseline — `proc_0_processrequest, proc_2_errormiddleware, Function:createLogEntry, Property:LogEntry.message` — with the return-shape coverage retained. The determinism guard then caught prose in the new DDL comment containing the token this repo scans for, which would have read as an unordered query. Reworded; that suite is doing exactly its job. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(processes): let a flow end where the program reaches outward The item three rounds kept circling. A trace was only emitted at a node with NO outgoing calls, so a real flow — scan, score, arm, PLACE THE ORDER — is always a PREFIX of some longer chain that runs on into date helpers, and could never be a process in its own right. Ranking could not fix that; the flow was never a candidate to rank. What blocked it was signal granularity, and the fix is the layer that was missing rather than a heuristic. GitNexus already knew where the program reaches outward: the parse phase collects fetch calls and ORM queries carrying `filePath` + `lineNumber`. Those facts only ever produced FILE-level edges (`File -[FETCHES]-> Route`), which cannot end a trace — every function in a file containing one would qualify. Attributing each site to the function whose range CONTAINS it turns the same facts into the function-level signal the walk needs: no new extraction, no new relation pair, no schema change. Innermost wins, so a closure that performs the call is the sink rather than the function spanning it. Three touch points, and the second is the one that makes or breaks it: - the walk emits at a sink AND CONTINUES, so `placeOrder` is an endpoint while `placeOrder -> formatDate` still exists separately; - subset-removal PRESERVES sink-terminated traces. A sink flow is by definition a prefix of the chain that runs past it, so emitting one at the walk and deleting it one step later would have been a no-op. Mutation- checked: removing this preservation fails all three sink tests, including the one asserting the sink is reached at all; - selection ranks sink-terminated above leaf-terminated, then by depth. `processes` now declares `parse` as a dependency. It historically avoided that on the grounds the dependency was spurious for a progress counter — it is no longer spurious, so it is declared rather than reached for implicitly, and the read fails open so a pipeline without that output detects no sinks instead of losing every process. Bounded honestly: this fires where fetch/ORM extraction fires. On the reporting repo it will do nothing until route detection handles hand-rolled dispatchers, since that codebase routes with `pathname === '/api/...'` on raw node:http and produces zero Route nodes — a separate gap, and the next one worth closing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(processes): the comment above the sink ranking still described it as unreachable R3-6 taught the walk what a sink is, but the block explaining the ranking still carried the paragraph written when that was out of reach — "a business flow still cannot be a process in its own right ... fixing that means teaching the walk what a sink is" — sitting directly above the code that does exactly that. A reader arriving at `rankedByInterest` would take the limitation as current. The measured-false fan-in finding stays; it is still true and still worth not re-deriving. What replaces the stale half is the bound that IS current: sinks fire where fetch/ORM extraction fires, so a codebase whose outward calls are not detected as such still sees leaf-terminated traces only. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(routes): read a route that is declared by a comparison, not by a framework `route_map` on the reporting repo returned {"routes": [], "total": 0, "message": "No routes found in this project."} for a codebase with SEVENTEEN route modules, an `apiRouteTable.js`, and 113 path comparisons. Not a partial answer — a statement about the code, and a false one. Same confident-empty class as the rest of this branch, except here it takes out a whole tool. Four route-discovery paths existed — filesystem convention, single-file framework route, cross-file framework route, decorator — and every one of them needs a FRAMEWORK to declare the route. A raw `node:http` server declares it the only way the language offers: if (req.method === 'GET' && pathname === '/api/live/portfolio') { … } A path, a verb, and a handler. Nothing in the pipeline could read it. The failure modes are not symmetric, so the rules are weighted accordingly: a route this misses is a coverage limit, a route it invents is `route_map` asserting something false. A comparison therefore qualifies only against a demonstrable request path (`pathname`, `*.pathname`, `req.url`; `path` is excluded — in Node it is overwhelmingly `node:path` or a file location), and anything untranslatable is dropped rather than approximated: - `pathname.startsWith('/api/')` is a namespace test; minting `/api` would claim a route nobody serves; - a bare `pathname === '/'` with no verb is more often the static-file normalisation branch (`pathname === '/' ? '/index.html' : pathname`) than a route — WITH a verb the intent is unambiguous, so that form IS taken; - an anchored regex converts only when its body is a literal path plus single-segment wildcards, so `/^\/api\/research-runs\/[^/]+$/` becomes `/api/research-runs/{param1}` while an optional group or an alternation bails. Three things went in that nobody reported, each found by measuring rather than by a second report. `switch (pathname) { case '/api/x': }` is the same dispatch in different syntax, and waiting for a bug report per shape is how a graph stays permanently one idiom behind the code it indexes. The reconciliation had to move up a level. The reporting repo keeps its path table (`isKnownApiPath`) in one module and its handlers in sixteen others, so a per-file rule sees each half separately and lists every route twice — once verb-less with the table as its "handler", once properly. Measured: 22 of the first 94 routes were that shadow. Only the whole registry can tell them apart, so the rule lives in the routes phase and touches dispatch-guard routes only — a framework route without a verb is method-agnostic BY DECLARATION (a Django function view, a Laravel resource), a fact rather than a weaker observation. And a path composed from a constant needed folding. One of those seventeen modules writes every one of its routes as `` `${autoTradeBasePath}/rules` ``, where the base is an alias of a module-level literal. Refusing that lost the whole file — and lost it INVISIBLY, since a module with unfoldable paths and a module with no routes are the same empty answer. Same-file only, literals only, one alias hop, and it refuses on ambiguity: a name declared twice with different values is dropped rather than guessed, because a partially-folded path is a wrong route and a wrong route is the failure this module exists to avoid. Wiring is a LanguageProvider hook, not a language check in shared code. `extractDecoratorRoutes` was already the general "route from this file's own AST" channel rather than a decorator-only one — express routes have flowed through it as `decorator-express.get` for a while — so the transport, the `(method, url)` dedup and the handler-symbol resolution all apply unchanged. `ExtractedDecoratorRoute.source` carries the one thing that genuinely differs: a decorator route is DECLARED, a dispatch-guard route is INFERRED. The walk is gated behind a substring pre-filter so it costs nothing on files that cannot produce a route, and the gate is sound by construction — every rule reaches a route only through `isPathExpression`, which needs one of exactly those tokens. SCHEMA_BUMP 49 -> 51, two entries. Decorator routes are worker output carried in the parse cache, so a warm cache replays results predating the extractor and `route_map` stays empty — the symptom this fixes, wearing the mask of "the extractor does not work". The second bump is the v34 hazard tripping again: a build stamped 50 had already been used to analyze before folding existed, so caches stamped 50 carry the unfolded route set. Caught by measuring — the post-folding run came back suspiciously fast and would have reported the pre-folding number. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): ask whether a value def is FUNCTION-LOCAL, not whether it is module-level The locality filter for value references was written as an ALLOWLIST of module-scope defs, and that shape cannot express a class member. A value def has three homes, not two: module level, a function body, and a CLASS body. Java and C# fields and Python class attributes live in the third, so an allowlist keyed on "module level" excludes every one of them by construction. The guard written to make that safe could not fire either. The set arms whenever a Module scope is FOUND, and Java has module scopes while having no module-level values at all — so for Java it armed permanently empty, which is exactly the state the guard exists to distinguish from "there genuinely are none". Inverting it removes the class. A blocklist of defs positively identified as function-local fails safe: a Java field, a Python class attribute, or a language whose scopes could not be inspected is emitted rather than dropped. That also retires the arming flag — an empty blocklist and an uninspected one mean the same thing, and both mean "emit". The failure mode moves from "silently deletes an edge class" to "retains an inert local", which is the right direction for a tool whose stated principle is that a confident empty answer is the worst outcome. MEASURED, because the review that prompted this reported it as a P0 deleting every Java/C#/Python field ACCESSES edge, and that half does not reproduce. Instrumenting the bridge over `java-write-access` shows ZERO value-ACCESSES candidates reaching the filter: Java field references resolve to a `Property` target and `isValueDefinitionLabel` covers only Const/Static/Variable, so the filter is never consulted there. Pipeline-level edge sets are byte-identical with the filter forced on and forced off, across four shapes — Java cross-file field writes, Java cross-file constant reads, Java bare same-class constant reads, and a Python module-constant/class-attribute mix. The defect is real and latent; the blast radius is not. Fixed anyway, because the predicate asks the wrong question and the next change that makes the bridge the sole emitter would ship the deletion for real. New `value-ref-locality.test.ts` pins the invariant triple — local dropped, module-scope kept, class member kept — by TARGET rather than by `reason`. The per-language suites filter on `rel.reason === 'read'|'write'` while the bridge stamps `scope-resolution: read|write`, so they are blind to bridge-side change in both directions. The file states plainly which half gates the mechanism (JS, mutation-verified) and which gates only the outcome (Java, because the mechanism is unreachable there), so it cannot be mistaken for a stronger gate than it is. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(docs): restore the agent guidance a generated-block refresh deleted Commit 8f8261021's message is entirely about cross-language anchor reporting; it also regenerated the `gitnexus:start` block in AGENTS.md and CLAUDE.md against a LOCAL, non-PDG index and swept six documentation/config files along with it. The review caught this and it is correct. Restored: - the index stats, which regressed 248612 symbols / 565510 relationships / 918 flows -> 29969 / 118986 / 762 — my machine's index described as the project's; - the whole `pdg_query` bullet and the PDG half of the impact bullet, while both capabilities remain live in `mcp/tools.ts` and `local-backend.ts`; - the "Inline staleness signal" section in the guide skill, content that never left `origin/main` and that this branch had no reason to touch; - `.mcp.json`, which had moved from `npx -y gitnexus@latest mcp` to a bare `gitnexus` — a fresh clone with no global install gets a dead MCP server. The worst of it is self-inflicted in a specific way worth naming: commit 411cac9b9, four hours earlier on this same branch, ADDED the instruction telling agents not to read `risk: UNKNOWN` as an all-clear. The refresh deleted it. So the branch shipped a new UNKNOWN verdict and simultaneously removed the guidance for reading it — the exact false-safe this PR exists to remove, reintroduced one layer up in the docs. Re-applied that guidance, and found the drift is wider than reported. The review noted the `.claude/` copy contradicting the plugin mirror; in fact the UNKNOWN block was present in ONE of five shipped distributions. `gitnexus/skills/` (the npm package), `gitnexus-cursor-integration/`, and `.agents/` were missing it too, so every non-Claude consumer of this skill had the old table. `shipped-skills-sync.test.ts` passed 54/54 through all of that. Its byte-identical check covers only the plan/work/review/lfg family, and the standard skills are guarded solely by per-skill fragment lists — so a fragment nobody listed is a fragment nothing protects. Added the UNKNOWN fragments to that list, plus a `copies.length > 1` assertion so an empty copy list cannot make the loop vacuous. Verified it fails against the pre-fix tree. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): require the return-shape producer to RESOLVE, not merely to name-match Review finding 2, reached independently by three Claude lanes and two Codex legs, and reproduced here. `emitReturnShapeMemberAccesses` took the receiver's type binding, then filtered a WHOLE-GRAPH property index with `idNamesMember` — a textual match on the node id. Any node whose id happened to read `<producer>.<member>` qualified, in any file and any language, and it emitted at the 0.9 PRECISE tier where a `minConfidence` floor cannot filter it out. The sibling unique-name pass was given a per-language restriction for exactly this hazard; this pass consumed the same shared index with none. Three guards, catching different shapes: - the producer must RESOLVE to a definition (`findCallableBindingInScope` — a CALLABLE lookup: the producer is the function whose return shape owns the member, and it resolves through finalized import bindings so a producer in another file still yields its own file); - the member must live in that definition's file; - that file must belong to the language being resolved. The third is not redundant with the second, which is the part worth recording. A receiver typed by CONSTRUCTION (`const bound = new Loyalty()`) resolves through the shared class registry, which is polyglot — so the producer resolves into `Loyalty.java`, its members legitimately live in that same file, and file equality waves the cross-language edge straight through. Also fixes the sibling P2: a site where the receiver IS typed to a producer that owns no such member now claims the site. That branch is the strongest negative evidence the pipeline can produce, and letting it fall through meant the 0.5 name fallback answered a question the precise pass had just DISPROVED — measured, linking a read to an unrelated same-named key in another file. `polyglot-property-isolation` gains the bound-receiver arm the review asked for, and it is the right arm: the pre-existing case has an untyped receiver and so only ever exercised the unique-name pass, while one extra token routes an identical read through this one. Mutation-verified — restoring the pre-fix matching makes exactly the new leak assertion fail. The first version of that arm was silently vacuous (it introduced a JS key of the same name, which destroyed the fixture's Java-only premise), which is why it now asserts on the TARGET FILE rather than on the absence of a name. KNOWN LIMIT, stated rather than papered over: a member-call producer (`const r = svc.make()`) binds `svc.make`, which resolves to no callable, so this pass now declines it. Codex B3 raised that converse case and it is real. Fixing it means typing `svc` and then finding `make` on that type — a larger piece of work, queued for the follow-up PR. Declining is the correct interim behaviour: the alternative is matching `make.<member>` by name across the graph, which is the fabrication this commit removes.

The out-of-core seal replaces `emitParsedFiles` with a scope-STRIPPED copy — that is its documented contract, scopes are reachable only via `scopeTree.getScope` afterwards — so under the seal the map came out empty, every `directImports` lookup returned undefined, and tier-2 narrowing died repo-wide. The reporting is the worse half. The loss surfaced as `ambiguous`, which means "several candidates and the pass refused to choose". The truth was "the evidence was discarded one function earlier". A reader acting on that would go looking for better receiver typing to fix a problem that was not there. This is the SECOND consumer of `parsed.scopes` on this branch to hit the seal. The first was hoisted above it. This one is converted to the point lookup instead, which is the stronger fix: a point lookup survives the seal by contract, so there is no ordering left for a future edit to get wrong. The parity assertion that would have caught it now exists. The sealed harness in `javascript-const-references` already ran the fixture both ways, but every assertion in it pinned ONE field's readers — which is exactly how a second instance slipped in, since no assertion happened to cover a narrowed name. It now also compares the WHOLE ACCESSES edge set between the two runs, as a sorted diff so a failure names the edges that moved, with a non-empty guard so two empty sets cannot compare equal and assert nothing. Mutation-verified: forcing the map empty fails it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): bind a producer's own returned key to itself, and stop claiming uniqueness for a ranked answer Review finding 3, accepting the two defects it demonstrates and declining the remedy it proposes. Both halves are mutation-verified. 1. A SITE INSIDE ITS OWN RETURN SHAPE NOW BINDS TO ITS OWN KEY. `export function buildB(row) { return { tickIntervalMs: row.b } }` writes the key that IS `buildB.tickIntervalMs`. Ranking declared anchors above return shapes is correct for a READ through a receiver, but applied to this site it handed the write to a same-named module const that `buildB` never touches — a wrong edge — while the node the key actually defines was left with no writer at all. Both halves wrong from one rule applied to the wrong shape. Checked before every other rule, because it is evidence rather than ranking: the owner qualifier on the candidate id and the enclosing callable are the same symbol. Nothing outranks that. 2. THE TIER NO LONGER LIES. `workspace-unique` is a claim that exactly one node in the workspace carries the name — a fact about the graph, and the label a reader trusts most. An answer reached by FILTERING (tests down-ranked, return shapes down-ranked) is a weaker claim, and it was reported under the same label. The edge is unchanged; what it is allowed to say about itself is not. `narrowed` now counts these correctly too, since it keys off the tier. WHAT I AM NOT DOING, and why. The review proposes dropping the same-file and imported-file tiers "and keeping only genuine workspace-uniqueness". That would revert the measured R2 result taking backend readers of `exitMinAtrMult` from 0 to 24. Workspace uniqueness was already measured too strict on that repo: the field carries 26 Property definitions — 16 in one-off scripts, 7 in the frontend, one in a test, and exactly one in the backend that reads it. Strict uniqueness declines all 24. The alternative suggestion — require the receiver to bind to the owning object — has the same effect by another route: the population this pass exists for is the untyped option bag, whose receiver binds to nothing. Requiring a binding turns the pass off for its own use case. So the two demonstrated defects are fixed and the capability around them is kept, at half confidence, naming its inference in the reason string, and honoured only where `fieldFallbackOnMethodLookup` allows. The R3-5 precision test needed rescoping rather than relaxing: it asserted that EVERY edge to the contested field is a precise return-shape edge, which the producer's own (correct, name-tier) write now violates. It asserts the reader edges are precise and the producer's write binds to its own key — two different claims reached two different ways, which is what the code now models.

It only surfaced now because a merge conflict had prevented CI from running at all, so nothing reported it. Re-baselined per the file's own instruction ("re-baseline intentionally on a legitimate capture change"), and verified first rather than rubber-stamped. The capture-name sets in both scope queries, diffed against `origin/main`: TypeScript + @reference.read.identifier (A2, bare-identifier reads) + @reference.type (R2-2, type references) JavaScript + @reference.read.identifier (A2) + @reference.read.destructured (R2-1c) + @reference.write.property-key (R2-1b) Nothing removed on either side. A pure superset is the check that no EXISTING capture moved — which is the failure mode a fingerprint guard exists to catch, and the reason to look before regenerating. Consistent everywhere else too: `capture_groups_small`/`_large` are unchanged (4503/14403) because those measure the SYNTHETIC scaling source this branch does not touch, so only the fixture-corpus number moves — 2097 -> 2338 across 21 new lang-resolution fixtures, 146 -> 151 files. Scaling stayed linear and inside budget (typescript 1.116, javascript 1.010, both < 1.5), so the added rules cost no super-linear time. Prior and new hashes are recorded in the baseline note, as every previous entry in that file does. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(bench): re-baseline the receiver-resolution drop guard for the new WRITE site kind Second of the two bench guards that had been failing for the whole PR without anyone seeing it — CI could not run while the branch was conflicted, so both went unreported until the merge cleared. The drift is a new site KIND, not a movement in an existing one: totalDropsAllKinds 129 -> 140 bySiteKind {call: 102, read: 27} -> {call: 102, read: 27, write: 11} `call` and `read` are byte-identical, which is the check that matters. This branch added write-site captures the corpus never had — `@reference.write. property-key` (R2-1b record construction) and the destructured-read rules — so write sites reach receiver resolution for the first time, and 11 of them have a receiver that does not resolve. A drop is the honest outcome for those; the alternative is the name-inferred guess this series spent three rounds bounding. Verified it is NOT caused by this session's review fixes before re-baselining: removing the `memberNotOnShape` site-claim added in 69047086 and re-running gives the identical 129 -> 140 / write: 11 drift, so the movement predates today and belongs to the capture work, exactly as the arithmetic above says. The sibling `scope-emission` guard still PASSES untouched, and the fingerprint guard passes after 20a937f4 — so all three arms of the benchmarks job are green locally. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(routes): track boolean polarity in dispatch guards, so a negated condition cannot invent a route Reproduced exactly as reported. `dispatch-guard.ts` refuses to inherit a verb from an `if` whose `else` branch holds the comparison — the module's own doc comment explains why: that branch runs precisely when the condition did NOT hold, so attributing it is backwards. `!` is the same fact written as an operator, and it was not handled. A stated invariant with half an implementation, which is worse than an absent one, because the comment reads as though it were covered. Measured against the real extractor before fixing: if (!(pathname === '/api/admin')) -> '' /api/admin INVENTED if (!(req.method === 'GET') && pathname === '/x') -> GET /x INVERTED if (!(req.method === 'POST' && pathname === '/w')) -> POST /w BOTH And the review is right that this is not additive-only. Driven through the real pipeline with a policy module that serves nothing plus a one-line route table, the invented `GET /api/report` collected into `verbedUrls` and `reconcileDispatchGuardRoutes` then EVICTED the true verb-less route for that path. A false route deleted a real one. After the fix that repo yields exactly one route, verb-less, path intact. Parity, not presence: `!!x` is `x`, so counting negations and testing the parity is the only rule that keeps a doubly-negated guard working. A negated VERB drops to verb-less rather than dropping the route — `!(method === 'GET')` means every method except GET, which no single value expresses, while the path evidence is untouched. Applies to the regex arm too; `!/^\/api\/x$/.test(pathname)` had the identical hole. Deliberately NOT keeping the `statement_block` break from the suggested patch. It is unreachable — the `!` in `if (!cond) { … }` lives in the condition, a SIBLING of the block, never an ancestor of anything inside it, and the only shape that puts a `!` above a block is an IIFE, which the function-boundary stop catches first. Unreachable in the UNSAFE direction, too: breaking early under-counts negations, and an under-count reads a negated guard as positive and invents the route. Verified by mutation — with the break present, deleting it fails nothing; the other three guards each fail a test when removed. Six new cases, all previously absent (`grep -c '!(' ` over both test files was 0, and the only negation covered was `!==`, the form that already worked). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(bench): re-baseline the emit-persistence byte-identity fingerprint for the isDetail column The third bench guard this branch left red, and the one the earlier rebaseline pass missed: the `benchmarks (GITNEXUS_BENCH)` job has never succeeded once in eleven attempts, and since step 11 aborts the job, the two steps after it — the streaming PDG-emit guard and the cross-language pipeline benchmarks — have never executed at all. [emit-persistence --check] FAIL: byte-identity fingerprint drift (got 4ee15e74…, expected 69e9182a…) Cause is this branch's own `isDetail` BOOLEAN on the Property table (PROPERTY_SCHEMA), which `streamAllCSVsToDisk` writes as one more header field and one more cell per Property row. Verified header-only rather than regenerated on faith. Dumping every CSV the bench emits on both `origin/main` and this branch and diffing them per file (name, byte length, sha256): the file set is identical at 35 CSVs, 34 of the 35 are byte-identical, and the sole difference is property.csv growing 68 -> 77 bytes as the header gains `,isDetail`. The synthetic graph mints no Property nodes, so not one data row moved — which is the thing this fingerprint exists to catch. Both timing gates were green throughout (scaling_ratio 0.783 against a 1.8 budget, elapsed_ms_large 229ms against the 1000ms backstop), so no throughput claim is being rebaselined away. Justification recorded in a `_rebaselined_<reason>` key, the convention bench/scope-capture/baselines.json already sets, and the note now says so explicitly so the next regeneration records its reasoning too.

The allocation, not the substring scan, is what the pass spends its time on. Nothing about breadth-first search made that safe. It only hid the cost by keeping traces short — measured on this repo the walk averaged 4.3 steps before D1 and 9.4 after, which roughly doubles both the number of surviving traces and the length of every key, so the same quadratic that was affordable under BFS is about six times the work under DFS. That is the whole of the slowdown D1 was carrying; the depth-first walk itself is cheaper than the queue it replaced (`pop()` against an O(frontier) `shift()`), and its frontier is bounded by depth rather than by breadth. Hoisting the join into a `uniqueKeys` array removes the multiplication. Measured back to back on one host, 5 reps, 25k callables, production sink path (main -> this branch before -> this branch after): deep_chain 876.8ms -> 1233.1ms -> 101.9ms mixed_cycles 731.4ms -> 1130.6ms -> 132.8ms shallow_wide 572.5ms -> 531.8ms -> 49.6ms and on the real gitnexus/src corpus (11,490 symbols) process detection goes 204ms -> 89ms against main, having been slower than main before. Output is unchanged, which is the property that matters here: swapping the file back and forth and diffing every non-timing field across all sixteen shape x scale x sink-variant configurations gives no difference, and the real corpus returns the same 936 processes / 4,648 steps either way. Sink keys are pushed alongside the traces they belong to, so the comparison set is the same set it always was.

Verified with a real `tsc --noEmit --strict` run over exactly that rename — the typed consumers error, this one did not. The runtime `.filter` stays, since it is the only thing actually guarding the cast. Also brings the phase docblock back in line with the deps array, which was missing `structure` (pre-existing) and `parse` (added by this branch), and records the two parse fields the phase now reads.

Gergő Magyar	997fc05b83	fix(resolution): resolve calls through a generic-typed field receiver in every language (#2833) (#2855) ... * test(resolution): pin generic-typed field receivers across languages (#2833) A field whose declared type carries a type argument (`repo: Repo<User>`) emits zero CALLS edges — not a truncated chain, not an edge to the interface declaration, nothing. This adds the cross-language matrix that measures it, modelled on the #2807 inferred-field matrix: every language runs the same two calls, one through a generic-typed field and one through a non-generic control field, and each language is compared against its OWN control row rather than an absolute edge count. Measured state, pinned here as `known-gap` so the file is green on main and flipping a row is a visible edit: affected TypeScript, C#, C++, Python unaffected Java, Kotlin, Go, Rust, Swift, Dart The unaffected six erase type arguments at interpret time (Java's `stripGeneric`, F41 #1928; Swift likewise). TypeScript, C# and Python instead run a container ALLOW-LIST that returns the type ARGUMENT, so a user-defined `Repo<User>` survives verbatim into a lookup that binds nothing. The `ts-local-vs-field` case is the bug in one file: `viaLocal` and `viaParam` both resolve for the identical type, and only `viaField` loses every edge — a bare name reaches Case 4 and its generic-aware lookup, a dotted field receiver does not. Negative controls pin what erasure must NOT do: an unbounded type parameter denotes no declaration, and a C++ explicit specialization is a different class from its primary template. The `Box2<T>` row pins a PRE-EXISTING false edge (a workspace class named `T`) so it cannot later be mistaken for fallout from this work. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * refactor(resolution): move resolveClassBindingForName to the shared walkers (#2833) Pure relocation, no behaviour change: the generic-aware class lookup moves from `passes/receiver-bound-calls.ts` to `scope/walkers.ts`, beside the bare `findClassBindingInScope` it wraps. Its two existing callers — `classifyReceiverOrigin` and Case 4 — import it from the new home and are otherwise untouched. The move is required rather than cosmetic: `receiver-bound-calls.ts` already imports from `compound-receiver.ts`, so having the compound receiver call into the pass would close an import cycle. `walkers.ts` is the shared floor both already depend on. Verified behaviour-neutral: the #2833 matrix is 44/44 identical before and after, across all fifteen fixtures. detect_changes attributes `resolveInheritanceBaseInScope`, `resolveQualifiedInheritanceBase` and `EMPTY_BINDINGS` to this commit; those are line-shift artifacts of inserting a function above them, and their bodies are byte-identical. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(resolution): type generic field receivers through the generic-aware lookup (#2833) A field receiver is spelled `this.repo` — dotted — so it types through the receiver-chain fold and the text cascade, both of which reach `findClassBindingInScope`. That function has no notion of type arguments, so a field declared `Repo<User>` resolved to nothing and the call site emitted NO edge at all: not the interface declaration, not the implementation fan-out, nothing. A local or parameter of the identical type is a bare name, reaches Case 4 and its generic-aware `resolveClassBindingForName`, and resolved fine. The bug was the asymmetry, not the generics. Three receiver-typing lookups now call the generic-aware helper instead: `typeOfMemberOnClass`'s primary and module-hoist branches, and the cascade's bare-identifier type-binding read. Every other one of the 38 `findClassBindingInScope` call sites is untouched — its own docstring records that widening it globally suppresses the `?? otherResolver(...)` fallbacks two dozen callers rely on, which would retarget inheritance edges, and impact rates it CRITICAL with 12 direct dependents. Order matters and is preserved: the helper tries the exact name, then an arity- and token-exact match against `def.templateArguments`, and only then falls back to the base name. Erasing first would collapse a C++ explicit specialization onto its primary template — `Vec<bool>` really is a different class. A bare type parameter carries no type arguments, so it never enters the generic branch and cannot be erased into a class that happens to share its name. Measured: TypeScript and C# generic-typed fields now emit exactly what their non-generic control rows emit, primary plus interface-dispatch fan-out. Java, Kotlin, Go, Rust, Swift and Dart are byte-identical. Both type-parameter negative controls are unchanged. C++ and Python are still open and stay pinned as known-gaps — they fail for different reasons and get their own commits. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(cpp,python): bind generic-typed member fields so their calls resolve (#2833) Completes #2833 for the two languages the shared resolution change could not reach. Each failed for its own reason, and both were found by measurement rather than assumed. C++ — a CAPTURE gap, not a resolution one. All three `field_declaration` type-binding rules required `type: (type_identifier)`, so a member declared `Repo<User> repo;` is a `template_type` and matched none of them: the field got no type binding at all, and every call through it lost its edge in both the bare and `this->` spellings. A LOCAL of the identical type resolved the whole time, because the local declaration rules gained their `template_type` variant long ago. Three mirrored rules close it, one per declarator shape (plain, pointer, reference). Written as separate patterns rather than one alternation: a node-type alternation in a field position is a tree-sitter 0.21 hazard this repo has been bitten by before. Python — the bracket spelling never entered the generic branch. Its `stripGeneric` is a container allow-list over `[...]` that returns the type ARGUMENT (`list[User]` to `User`), so a user-defined `Repo[User]` matched nothing and survived verbatim, and the shared lookup's generic branch is gated on `<`. It now reduces a subscripted type neither allow-list claims to its base name — the same rule Java and Swift already apply to `<...>`. Deliberately the LAST resort: a container must reach its own rule first, or `list[User]` would type the receiver as the container and retarget every call in a for-loop chain. The as-written spelling survives on `TypeRef.declaredSpelling`, which is what the fold's index step reads. Both are parse-time and land in the cached ParsedFile, so SCHEMA_BUMP goes 45 -> 46 with its pin test. Verified free against origin/main; the ledger in that file records three prior EXACT clashes, so re-check again immediately before merge. The matrix now covers the spellings real code writes, all measured: a nullable generic, a bounded wildcard, a raw type, a nested generic and a multi-argument one. None needed work beyond the shared lookup, which is the evidence that base-name erasure is the right primitive. The C++ specialization control now asserts what it was written for: `Vec<bool>.save` and `Vec.save` are DIFFERENT target ids, so the arity/token match still wins over erasure. scope-capture is byte-identical for cpp and c, so no rebaseline — the bench corpus contains no generic-typed member field, which is worth its own coverage issue. Two pre-existing gaps were measured and are deliberately NOT fixed here, because in both cases the language's own non-generic CONTROL row fails identically: C++ `this->field.m()` emits nothing, and JavaScript/PHP docblock-declared field types bind nothing at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(python): do not reduce containers or typing special forms to a base name (#2833) Review finding on this branch's own Python change, caught by probing the interpreter directly rather than by reading it. The base-name reduction was reached by FALLTHROUGH: "neither container rule matched" was treated as "not a container". It is not, and two measured shapes proved it: dict[str, list[User]] -> dict (was: the annotation, intact) Dict[str, Repo[User]] -> Dict Callable[[int], User] -> Callable Literal["a"] -> Literal Union[A, B] -> Union tuple[int, ...] -> tuple The dict rule's value group cannot span a nested `]`, so a nested value declines and falls through — and the dict rule's own comment says that shape is deliberately "left for a downstream strip pass". Collapsing it to `dict` destroyed the value type instead. The typing SPECIAL FORMS are worse: `Callable`, `Literal`, `Annotated` and `Union` are not classes, and reducing them to a bare name binds any workspace class that happens to share it — a fabricated edge, which is strictly worse than the missing edge #2833 set out to fix, and those names are ordinary enough for a real codebase to declare. Reduction is now guarded by an explicit deny set covering the containers the two allow-lists already own and the typing special forms. Everything named there keeps its as-written text and resolves exactly as it did before #2833. `arr[0]` also reduces to `arr` in isolation, but that is unreachable and is now documented as such: every Python `@type-binding.type` capture is a `(type)`, `(identifier)`, `(attribute)` or `(dotted_name)` node, so a subscripted VALUE expression never reaches the interpreter. Pinned by a new unit test that asserts all four groups — user generic reduces, container reduces to its ELEMENT, declined container shape stays intact, special form untouched. Reverting the deny set fails three of its five cases. Also corrects `resolveClassBindingForName`'s docstring, which this branch had made false: it claimed only `classifyReceiverOrigin` passes the decoration stripper, while the three receiver-typing lookups in compound-receiver.ts now pass it too. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(resolution): rank base-name candidates lexically and refuse arg-pinned defs (#2833) Review of #2855 found that this PR turned a MISSING C++ edge into a CONFIDENTLY WRONG one — the direction this subsystem calls unrecoverable. `resolveClassBindingForName` ended with an unguarded base-name fallback that returned the first same-named class the scope chain reached. A C++ primary template carries `templateArguments === undefined`, so it can never satisfy the exact-args branch, and every non-specialized instantiation fell through to that fallback. Measured through the real pipeline: with the primary forward-declared and the specialization defined first, `Vec<int> vi; vi.save()` emitted `Vec<bool>::save`. Declaring the primary first gave the correct target — selection was SOURCE-ORDER DEPENDENT. Two more triggers behaved the same way: a partial specialization (`Vec<int*>` against `Vec<T*>`), and lexical shadowing between a global `Box<bool>` and a namespaced `N::Box<bool>`. Two changes, neither of which is any of the three remediations the review proposed — each was rejected on measured evidence: - Exact-argument matching is now LEXICAL-FIRST. Candidates come from the scope chain, and the workspace-wide qualified-name bucket is consulted only when the chain produced no exact match, so cross-file specializations still bind. - The base-name route refuses a definition that pinned its own template arguments: if the fallback's answer carries `templateArguments`, the visible candidates are re-decided with those removed — exactly one, or decline. Why not the filed options. "If specializations exist and none matches exactly, return undefined" deletes a green committed row (`neg-cpp-specialization/runInt` legitimately resolves to the primary). "Resolve all defs for the base name, return only on exactly one" deletes a working edge for C# `partial class Repo<T>` split across files — two unspecialized defs under one name is legitimate, and `QualifiedNameIndex`'s own docstring names that case. Preferring the primary alone fixes nothing about shadowing, which is a ranking bug. The guard is expressed as `carriesOwnTemplateArguments`, not as "specialization", so shared pipeline code still names no language (AGENTS.md R6). It can only fire where a declared name carries concrete arguments — measured `undefined` for `class Repo<T>` in TypeScript and C# and for a C++ primary template — so the blast radius is bounded to C++-style specializations. Partial-specialization SELECTION is deliberately not implemented: choosing `Vec<T*>` for `Vec<int*>` needs template-argument deduction, which is a semantics expansion and cannot live in language-neutral shared code. The source-order dependence is what is fixed; the answer is now deterministically the primary. Also in this commit: dropped an unreachable `?? []` (QualifiedNameIndex returns a frozen empty array on miss by contract) whose comment was wrong on both clauses; made the docstring true about argument ERASURE being what widens what binds, rather than only the decoration stripper; and corrected a stale pointer that still placed `resolveClassBindingForName` in `receiver-bound-calls`. `findClassBindingInScope` itself is untouched — 38 call sites, CRITICAL. Verified: matrix 56/56, cpp.test.ts 334, unit scope-resolution 1505. Mutation proof: reverting this file fails the three trigger cases and passes the non-regression cases; restoring it passes all five.

The structural cause is PEP 585: nearly every container has two spellings differing only in case (`deque`/`typing.Deque`, `frozenset`/`FrozenSet`). Exact matching forced every pair to be listed twice, so any half-pair was a silent escape. The deny lookup is now CASE-FOLDED, which closes that axis by construction — `Deque` becomes impossible rather than remembered. `SINGLE_ARG_CONTAINERS` and `MAPPING_CONTAINERS` are now the single source of truth: they build the two container regexes (verified byte-identical `.source` and `.flags`, so zero behaviour change) and feed the property test. The deny set is re-scoped to a closed, auditable universe — the documented Python stdlib type-system surface — and grew 39 -> 65 concepts: the `collections.abc` views, `contextlib` managers, `re.Pattern`/`Match`, the `IO` family, ordinary-named stdlib generics (`Queue`, `Task`, `Future`, `PathLike`), the remaining typing special forms, and the generic machinery (`Generic`, `Protocol`, `TypeVar`...). Third-party generics (`Mapped`, `QuerySet`, `Model`) are deliberately NOT added and are pinned as a decision: that universe is open, enumerating it only chases the last escape, and declining `Model` would cost real edges in the many projects that declare one. The review's suggested property test — derive the names from the `single`/`dict` regex sources — would NOT have caught `Deque`: `deque` appears in neither regex, only in the deny set. Both properties are implemented, since they catch different drift. The unit test was also TAUTOLOGICAL: it asserted members OF the deny set, so it structurally could not detect an omission. It now asserts case-fold closure and PEP 585 alias coverage, and the capture fixture drops its `as unknown as` cast for the fully-typed helper pattern the sibling `java-interpret.test.ts` already uses. Still at interpret time, so no further SCHEMA_BUMP (already 45 -> 46). Proving the base is a class the FILE can see — the real fix for the remaining exposure, since `findClassBindingInScope` binds any name with exactly one workspace def regardless of scope or imports — is a follow-up, not reachable from this file. Mutation proof: restoring HEAD's deny-set contents and exact-match lookup fails four assertions including the `Deque` pair, with the pre-existing guard rows still passing; restoring gives 125/125.

"C++ fixed" was overstated. Six new patterns — three declarator shapes (plain, pointer, reference) by two qualifier depths — written as separate patterns rather than one alternation, keeping the tree-sitter 0.21 field-position discipline the existing rules follow. The design choice was measured, not assumed. Codex suggested preserving the full qualified spelling and normalizing `::`; preserving resolves NOTHING, because `findClassBindingInScope`'s dotted-tail fallback splits on `.` while C++ writes `::`, and `ns::Repo` is not an index key either (C++ emits no `@declaration.qualified_name`). Measured: `ns::Repo<User>` resolves to nothing, `ns.Repo<User>` resolves to `Repo`. Since a tree-sitter capture is a NODE and not synthesized text, the only lever is which node to capture — so `@type-binding.type` goes on the INNER `template_type`, dropping the qualifier and landing on the same single-match-or-decline path the bare spelling already takes. Qualifier depth 3+ (`a:🅱️:c::Repo<User>`) remains uncaptured. Stated as a limit and pinned by a test row, not claimed as fixed. The bench blindness the review identified is also closed. The `scope-capture` C++ corpus contained ZERO template-typed member fields — confirmed a fourth way by applying six demonstrably behaviour-changing patterns and getting a byte-identical fingerprint. The corpus now carries generic and qualified-generic members, and the gate is load bearing for the first time: three states that all hashed to 856d02f3 before now differ (pre-#2833 0e7cbda7, +this PR's 3 rules de07d8b5, +these 6 rules bd47c82d). Rebaselined for cpp only; c is unchanged. Histogram diff: only 5 tags move with the fields, each by exactly +40 (20 entities x 2), and every `@reference.*` count is unchanged. Over-match is preserved: 20 shapes still produce no field capture, including the 8 original method/pointer/reference/function-pointer/ using/typedef/friend/operator forms plus their `std::`- and `a:🅱️:`-qualified variants. Not fixed here, deliberately: NON-generic qualified fields (`ns::Address addr;`, `std::string name;`) still capture nothing. Closing that needs six more patterns and would newly bind every `std::string`/`std::mutex` member repo-wide, changing edges far outside #2833. Separate issue. The template-template-parameter hazard the review filed against these rules is NOT capture-side: a tree-sitter query has no scope knowledge, so it cannot know `Map` is bound by the enclosing `template <...>` header, and the PRE-EXISTING `type: (type_identifier)` rule already captures a bare `T item;` and erases it the same way. It is handled by the lexical ranking in `walkers.ts` in this series. Mutation proof: reverting this file fails 9 of 32 assertions (all eight qualified spellings return no capture) while every over-match negative still passes; restoring gives ALL PASS. Bench `--check` passes for all 15 languages.

The rows that discriminate against the resolver fix (they fail if `walkers.ts` is reverted): - C++ specialization must not depend on DECLARATION ORDER: the forward-declared-primary/specialization-first arrangement must land on the primary, same as the mirror arrangement. Plus a cross-case property asserting the two independently built fixtures agree. - Partial specialization is deterministic in both orders. The note says explicitly that selecting `Vec<T*>` would need argument deduction and that flipping this row later is a deliberate expansion, not a regression fix. - Lexical shadowing: the namespace-local `N::Box<bool>` wins for a field inside `N`, and the global specialization wins at global scope. The NON-REGRESSION rows are load-bearing — they are why two of the three proposed remediations were rejected: cross-file C++ specialization binding, and C# `partial class Repo<T>` split across two files with the field in a third (two legitimate unspecialized defs under one name). Coverage the review found missing: C++ pointer and reference generic fields (two of this PR's three original rules had ZERO coverage); all six qualified patterns plus the depth-3 boundary pinned as empty; TS/C# multi-arg container collision; an anti-vacuity sibling for `neg-bounded-type-parameter`; Swift/Dart rows restructured so the ANNOTATION is the only possible source (the old rows gave the field an initializer of the same generic type and could not tell which resolved); and cross-file, inheritance/MRO, import-alias, static-member and the TypeScript module-hoist branch. Six things were measured and pinned AS MEASURED rather than asserted as wishes, each flagged in its row note: a static/class-level member emits nothing for generic AND non-generic alike (a static gap, not a generics one); a cross-file C++ primary template does not bind while the cross-file specialization does; `std::unique_ptr<Payload>` types to `unique_ptr` rather than `Payload` (smart-pointer transparency is not applied on the qualified path); two same-named C++ specializations in one file collapse to one node id; and the container-name collision (`Map<string, User>` binding a workspace `class Map`) is recorded as INTENDED, since the annotation does name that class. The `new Set(...)` dedup was kept rather than narrowed: a per-case surplus-edge sweep measured ZERO duplicate edges anywhere in this file, Swift included, so the quirk that justified a blanket dedup does not reproduce. The sweep now pins zero surplus per case, so a real double-emit fails instead of being absorbed. The file is deliberately NOT split: four assertions compare cases against each other, cost is linear in cases, and the 1,800,000 ms `beforeAll` is kept because the same run measured 271-428 s depending on host load — a tighter bound converts contention into a red suite. The reasoning is recorded in the file header. Also corrects the SCHEMA_BUMP pin-test title, which still said (#2766). Mutation proof: reverting `walkers.ts` fails exactly the five order and shadowing assertions and passes the other 109; restoring gives 114/114. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * feat(resolution): capture declared type parameters so a type variable is not a class (#2833) Three review findings were blocked on one missing fact. `templateArguments` records the arguments a declaration was written AGAINST (`struct Vec<bool>`); nothing recorded the parameter list a declaration DECLARES (`template <class T>`, `class Box<T extends Repo>`). So the resolver could not tell a type variable from a class, and: - `class Box2<T> { t: T }` beside a workspace `class T` emitted a FALSE edge `run2 -> T.foo`. `T` carries no type arguments, so it never entered the generic branch — the plain lookup simply bound a same-named class. The lexical grounding added elsewhere in this series cannot help, because `export class T` IS lexically bound. - `class Box<T extends Repo> { t: T }` resolved to nothing: no recorded bound to resolve through. - A full specialization `template<> struct Vec<T*>` and a partial `template<class T> struct Vec<T*>` were byte-identical (`['T*']`). `SymbolDefinition.typeParameters` now records `{ name, bound? }` in declaration order (substitution is positional). `bound` is kept verbatim and un-split, so `Repo & Closeable` stays whole; ABSENT means UNKNOWN, never "unbounded", which is what keeps unconverted languages behaving exactly as before. Transport is the raw parameter-list node via `@declaration.type-parameters`, read by a language-neutral parser that recognizes TOKENS, not languages: `extends`/`:` introduce a bound, the name is the trailing identifier, so `class T`, `typename T`, `in T`, `out T`, `reified T` and `class... Ts` are one rule. Populated for TypeScript, C++, Java, Kotlin, C# and Rust. JavaScript, C, COBOL, PHP and Ruby have no declared type parameters to capture; Go and Python spell them with SQUARE brackets, which this parser deliberately rejects as ambiguous against subscript and array spellings (Go already has a working main-thread sidecar in this series); Dart and Swift are straightforward follow-ups. Two latent hazards found and closed on the way: - The new capture was not in `KNOWN_SUB_TAGS`, so it could out-span its own declaration and become the anchor — silently DROPPING the whole class def. - A templated C++ struct matches both the standalone and `template_declaration` patterns, minting two defs under one id, and only one twin could see the parameter list. `buildDefIndex` is first-write-wins, so MATCH ORDER decided whether `Vec` remembered `T`. A narrow duplicate-declaration backfill gives both twins the list. Also fixed by its own test: a Rust lifetime `'a` parsed as a parameter named `a`, which would have shadowed a real class. Parse-time output lands in the cached ParsedFile, so SCHEMA_BUMP goes 46 -> 47. Re-checked against origin/main at write time: main is on 45; 46 was taken by this same branch, and a warm cache stamped 46 carries ParsedFiles with no `typeParameters` at all. The csharp and rust capture goldens were regenerated with the tests' own documented `UPDATE_GOLDEN=1`; only digests moved, no captureGroups.

Base-name erasure (`Repo<User>` -> `Repo`, `Repo[User]` -> `Repo`) bound through a workspace-wide qualified-name fallback that consults NO scope, NO import and NO module — it bound any name with exactly one workspace def. That is why a Python `Mapped[User]` could bind an unrelated `class Mapped`, and why the language deny lists were papering over an open universe. `resolveErasedBaseName` now admits an erased base on one of four grounds, strongest first: the scope chain binds it; the declaration is in the SAME FILE; the index proves the name is a template family; or the file binds no cross-file class at all, so its silence is no evidence. The last ground fails toward permissive on purpose — every way it can be wrong costs a wrong edge that already existed, never a working one. Two measurements drove that design and refuted the simpler rule. A C++ `#include` materializes NO binding whatever, and C# resolves cross-namespace without `using` through the index — so a pure "require lexical grounding" rule would have deleted every cross-file C++ generic member. Both are now pinned. Python erases at CAPTURE time, so by resolution there is no `<` and the grounded route was never entered. `erasedTypeApplication` rebuilds the application from `TypeRef.declaredSpelling` — strictly: the raw name must be the base and the argument list the whole balanced remainder, so `User[]`, `vector<Item>` and `Repo<User>?` decline and behave exactly as before. Closing it took finding FOUR emitters, not one. Three were in Case 4; the fourth was `emitReferencesViaLookup` re-emitting the refused edge from the pre-resolved reference index, which needed the site marked handled with a recorded `receiver-unresolved`. A fifth lived in the text cascade: a declined fold falls THROUGH by design, and the cascade held its own ungrounded copy of the member-typing lookup. This file typed a receiver from a `TypeRef` in five places and the PR had wired three; all five now go through one `classOfDeclaredType`. Also here, from the same review: - Type parameters no longer bind a same-named class (uses the new `typeParameters`), and a BOUNDED parameter resolves through its bound. - A cross-file C++ PRIMARY template now binds: a ranking bug, not a capture one — the index fallback needs exactly one candidate and `Vec` held two, so removing the argument-pinned declaration leaves one. - `this->field.m()` resolved to nothing for generic AND non-generic alike. A language that declares `this` IS the enclosing class (`resolveThisViaEnclosingClass`) synthesizes no `this` typeBinding, so a chain whose BASE is `this` could never seed its head. Reading the provider flag keeps the rule language-free. - Class-level (static) member receivers emit nothing in TypeScript and Kotlin — for the non-generic control too. Case 6 types them from the DEF side (`isStatic` + `declaredType` on the field node), which needs no capture change; the target lookup stays the ordinary instance walk, so a static field HOLDING an instance still binds an instance method and a genuine static call is untouched. Partial-specialization SELECTION is deliberately not implemented: it needs argument deduction against a parameter list, and full C++ partial ordering is a real algorithm with no measured driving case. The discriminator now exists if someone wants it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(cpp,js,php,go): close the remaining per-language generic-field gaps (#2833) Four language gaps the review measured, each with a different cause. **C++ qualified member fields.** `std::vector<Item> items;`, `ns::Repo<User> r;` and `ns::Address addr;` captured NOTHING: every field rule required the type node to BE a `type_identifier` or `template_type`, and a qualified member type is neither — tree-sitter wraps both in a `qualified_identifier`. Three depth-agnostic rules (one per declarator shape) now match the outer node, which also REMOVES the depth boundary rather than raising it: depths 1-4 capture, generic and non-generic alike. Preserving the qualifier resolves nothing — measured: `ns::Repo<User>` binds neither way, because the dotted-tail fallback splits on `.` while C++ writes `::`, and `ns::Repo` is not an index key. Since a capture is a NODE and not synthesized text, the qualifier is dropped in `interpret.ts` by a top-level-only `::` split, so `std::vector<std::string>` reduces to `vector<std::string>`, not `string`. Measured cost of the non-generic half, which was the reason to hesitate: field captures go 8 -> 32 across the C++ bench corpus, but the resolution-level census over those 13 repos is 32 CALLS edges before and 32 after, BYTE-IDENTICAL. It fabricates only where a workspace class shares a std name (`class string` beside `std::string name;`), which is the same accepted policy the already-landed qualified-generic rules carry, pinned in the matrix as intended. **JavaScript `@type {Repo<User>}` and PHP `@var Repo<User>`.** Neither bound a field type — and neither did the NON-generic control, so this was a docblock gap rather than a generics one. PHP needed TWO captures, not one: with only the type binding, `$this->repo->save()` resolved until a second class declared `save` and then went unresolved, because narrowing a same-named method needs the receiver's member owned. Generics do NOT come free in PHP — `normalizePhpType('Repo<User>')` returns `'User'` by the container-element convention, so passing the raw spelling through would have emitted `User::save`; type arguments are erased at capture instead. In JavaScript they DO come free, verified byte-identical to the TypeScript control. Both decline what they cannot prove: arrays, `list<User>`, unions, `Promise`/`Array` wrappers (via an exported predicate rather than a copied name list), statics, and any property that already has a native type. **Go generic interfaces.** `UserRepo` genuinely DOES implement `Repo[User]` — the spec says a generic type must be instantiated, that instantiation substitutes type arguments and yields a new non-generic type, and that a type implements an interface when it is in its type set. So the old behaviour was a FALSE NEGATIVE and the matrix note calling it "already correct" was wrong. Satisfaction is now checked against POSITIONALLY SUBSTITUTED method sets, so `Repo[Order]` does not match a `Save(x User)` implementor — substitution, not erasure. #2829's exact method-set model is untouched: pointer receivers still follow MS(*T), unexported names stay package-scoped, the declaration's own method set is still checked first, and the harvest is gated so a repo with no generic interface never runs it. `go.test.ts` is unchanged at 296 passing.

All eight are flipped, and the prose describing them as open gaps is corrected. Nine new cases cover the fixes that would otherwise have shipped unpinned. Flipped, each measured: the type-parameter FALSE edge (`run2`) is gone; a bounded parameter now resolves through its bound with fan-out; the cross-file C++ primary binds; the C++ qualifier depth boundary is removed rather than raised; Go gains its two structural implementors and JOINS the paired sweep, which had quietly excluded it — that exclusion was the taxonomy admitting a bug; and both static-member rows resolve. Added: JS `@type` and PHP `@var` docblock fields with three PHP declines; a Kotlin `companion object` receiver (given an INTERFACE control so the paired sweep can check it, which `ts-reach-shapes` cannot — its two sides are not count-comparable); the Python third-party grounding refusal plus the ground that still ADMITS, so an empty row can never be read as "erased names never resolve"; the four mirrors that would break if grounding were tightened (same-file and imported Python, a C++ `#include`, C# cross-namespace without `using`); C++ qualified non-generic fields including the fabrication policy and its absence case; `this->field.m()` for generic and non-generic with bare controls; and a Go negative proving substitution is positional, not erasure. Three shapes are pinned AS MEASURED with notes saying they are deliberate limits so nobody "fixes" them by accident: C++ partial-specialization selection is deterministically the primary (real selection needs argument deduction); `std::unique_ptr<T>` types to the pointer, not the pointee (`.` and `->` are indistinguishable to the resolver, so transparency would trade a recoverable miss for a confident wrong edge); and two same-named C++ specializations in one file collapse to one node id, which is why the shadowing fixture uses two files. One row pins a REMAINING wrong edge rather than hiding it: `m.inner.ping()` on a `Mapped[User]` head still binds the unrelated workspace class, while the one-segment-shallower `m.save(u)` correctly declines. The obvious one-line guard was written and MEASURED not to close it, so the surviving route is elsewhere and wants its own diagnosis — a broader refusal would change chain-head resolution for every language without pinning the shape it is meant to fix. `bench/scope-capture` is rebaselined for the six languages whose captures moved, regenerated from a fresh measurement rather than pasted; `--check` passes for all 15. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * perf(resolution): remove three measured hot-path regressions this series added (#2833) A quality pass over the #2833 series found three performance defects it had introduced, all measured, plus dead code and stale docs from six agents having appended to the same files across four rounds. No behaviour change: the resolver suite is identical before and after, and every scope-capture fingerprint is byte-identical. **An accidental quadratic in Go instantiation harvesting.** `collectGoInstantiations` calls `record()` for every type binding and every declared, return and parameter type in every Go file, and the `includes('[')` gate does not filter Go's most common types — `map[string]string`, `[]map[string]*v1.Pod` and `map[string]map[string]int` all produce a `map` candidate. Each false base then failed a full scope-chain walk and fell through to a LINEAR SCAN OF EVERY INTERFACE IN THE PROGRAM, with no dedupe on the spelling, so the same `map[string]string` written 10,000 times paid 10,000 scans. Now a qualified-name index built in `buildDetectionIndexes` (one probe, ambiguity semantics preserved exactly) plus a per-scope base memo: 8,000 interfaces / 80,000 spellings: 6,662 ms -> 104 ms (64x) `resolveEmbeddedInterface` held a byte-identical copy of that scan and now shares the helper. `GoInstantiation` was a single-field wrapper and collapses to the array it wrapped; its two parallel maps fold into one whose inner key IS the dedupe. `candidateStructIdsFor` was rebuilt per instantiation although every substituted method set has the same key set — hoisted, and materialized, because one branch returned a live iterator that would have yielded nothing on a second pass. **`scanForCrossFileClass` asked a name-keyed question that needs no name key.** It answered "does this file bind any cross-file class" by probing every accessible namespace once PER NAME. It now iterates the channels directly, taking whichever side is smaller so a large namespace table cannot reintroduce the product. Predicate and early exit preserved: 5,000 module names x 1,000 namespaces: 159.0 ms -> 1.2 ms (132x) **A duplicated scope walk on every generic receiver.** `resolveClassBindingForName` computed the lexical candidate list, then `resolveErasedBaseName` recomputed the identical `findAllBindingsInScope`. Computed once and passed: receiver at depth 8: 5,617 ns -> 3,091 ns (-45%) **A whole extra AST traversal per JavaScript and PHP file.** The docblock synthesis passes each added a full tree walk to find one node kind — the ninth in the JS emitter, the third in PHP. `node.namedChildren` materializes a wrapper array across the N-API boundary for every node, so one added pass cost 1.9x what parsing the entire file costs. Folded into the existing walks as one more node kind; capture output is byte-identical and every fingerprint is unchanged. Total emit time per file drops 4-7%. Hygiene, all verified stale rather than assumed: - `receiverOriginOpts` passed `resolveThisViaEnclosingClass`, which `classifyReceiverOrigin` never reads — the "both hooks" comment above it is true again. - The `stripDecoration` docstring's caller roll-call claimed the only edge-emitting caller "emits no edge and can only change a diagnostic label". Case 6 passes it and does emit edges. Replaced the roll-call with the rule; six rounds each appending a name to a list is how it went wrong. - A Python comment described the resolution-time grounding as a follow-up that "this parse-time pass cannot do" — it landed in this same branch and is pinned by `py-erased-grounding`. - `classOfDeclaredType` took a `scopeId` all five callers derived from the `TypeRef` they also passed. Dropped, so "these five are the same call" is enforced rather than asserted. - Three exports with no consumer outside their own file. - PHP had three copies of one preceding-comment sibling walk and two regexes for one tag, so a fix to either reader of `@var` would land on one and not the other — the symptom being a field typed differently from its own foreach element type. One walk, one regex. Tests: the new matrix leaked a fixture repo per case; it now carries the sibling suite's `cleanupTempDirSync` and the Windows EBUSY reasoning that goes with it. `PAIRED` was a second hand-maintained list and 19 of 41 cases had silently fallen out of it — it is derived from the cases now, with a new assertion that each case is either swept as a pair or carries a written reason it is not. That recovered one genuine omission (`php-typed-property`). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * test(bench): rebaseline receiver-resolution for the #2833 this-> fix The `Receiver-resolution drop guards` CI step failed on this branch: shapeArm.cpp.fieldReceiverCall: "INVISIBLE-GAP" -> "RESOLVES" shapeArm.cpp.decoratedFieldType: "INVISIBLE-GAP" -> "RESOLVES" Both are the intended improvement. The guard is exact-match by design — the drop count cannot move without a deliberate rebaseline, and the rebaseline path demands the movement be explained — so this records the two shape flips and leaves the call-drop count arm untouched. BASELINE.md still claimed `this->repo.save()` and `this->repo->save()` were INVISIBLE-GAP. That is now false: the `resolveThisViaEnclosingClass` head seed added in this PR resolves both. Also notes what the control established — this was never a generics gap, since the non-generic control failed identically before the fix. * docs(parse-cache): narrow the SCHEMA_BUMP ledger to what the bump delivers The ledger claimed a warm cache would make "the whole fix ... a silent no-op on every incremental analyze". That overstates the constant. The bump invalidates the PARSE half; whether the re-parsed captures reach the graph is gated separately and does not move: - `isIncremental` (core/run-analyze.ts) tests `!options.force`, an existing meta, `!schemaFingerprintMismatch(...)`, feature parity, non-empty `fileHashes` and a git repo. SCHEMA_BUMP is in none of them. - the incremental branch writes back only `hashDiff.toWrite` and logs the rest as "unchanged file rows preserved". - SCHEMA_FINGERPRINT hashes node/relation DDL, untouched here, so it is byte-identical and moves nothing either. So an incremental analyze re-parses an unchanged file correctly but keeps its existing rows; the new edges land on the next full rebuild. That is the pre-existing contract for every capture change, not a regression in this PR — but the comment should not promise more than it delivers. Comment only; no behavior change.

Gergő Magyar	aaa78f9590	fix(scope-resolution): fan out interface dispatch from Case 3b receivers (#2832) (#2842) ... * fix(scope-resolution): fan out interface dispatch from Case 3b receivers (#2832) Case 3b (chain-typebinding) folds a receiver through the same `resolveCompoundReceiverClass` call and the same `[owner, ...mroFor(owner)]` walk Case 0 uses, but emitted its edge without calling `emitInterfaceDispatchFor`. When that fold landed on an Interface the site got one edge to the interface's bodiless declaration and none to any implementation — the defect #2813 reported for field receivers, in the half #2829 did not cover. The gap was a property of how a receiver was SPELLED rather than of what it resolved to. `d.repo.save()` contains a dot, so it took Case 0 and fanned out; binding the identical field to a local first — `const r = d.repo; r.save()` — made the receiver a bare name with a dotted typeBinding, which is Case 3b, and lost every implementation edge. `ownerDef` is the receiver's own folded type, matching Case 0's `currentClass` and Case 4's `ownerDef`, not the owner of the member the MRO walk settled on: a receiver folding to a concrete class that merely inherits an interface method must not fan out, because its runtime type is that class. The closure self-gates on `ownerDef.type !== 'Interface'`, so the call is inert for every concrete receiver and needs no language check. Confidence is the 0.85 literal this case's own primary emits, so dispatch edges never outrank the edge they hang off; Case 4's site.kind-dependent value has no counterpart here because Case 3b's primary does not vary that way. The new fixture pins the route as well as the fix. `const r = d.repo` reaches Case 3b and nothing else can take the site: Case 0 needs a `.`/`(` in the receiver name or a minted receiver chain, and `encodeReceiverChain` returns undefined for the empty step list a bare identifier produces; Case 4 excludes itself on the dot. Before the fix the primary assertion passed while the fan-out came back empty — the exact "reached Case 3b and stopped at the declaration" signature. Resolution-side only: this changes what the resolver produces, not how it is stored, so no SCHEMA_BUMP applies. An existing index must be re-analyzed to show the new edges. Follow-up from #2829. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(scope-resolution): record Case 3b's interface-dispatch fan-out in I4 (#2832) Invariant I4 documented the fan-out as something "Cases 0 and 4 both perform" and spelled out Case 0.5's exclusion, while saying nothing about Case 3b — which is what made 3b's missing fan-out an undocumented asymmetry rather than a deliberate exclusion someone could defend or point at. With the fan-out added, Case 0.5 is the only case that folds or walks to a receiver type without dispatching to implementations, and its exclusion is gated behind `resolveThisViaEnclosingClass`. Saying so explicitly keeps the next reader from having to re-derive which cases fan out by reading the pass. Comment-only; `detect-changes --scope staged` reports no graph change. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(scope-resolution): add the concrete-implementor control for Case 3b (#2832) The Case 3b fan-out shipped with one negative control — a chain folding to PlainCache, a class that implements nothing. That proves only the weak claim: no interface anywhere near the site, no fan-out. Add the stronger negative. SqlRepo implements Repo, so an interface IS in scope and `save` is a name Repo declares, yet the receiver's folded type is the concrete class and nothing may fan out. This is the control that fails if a later change fans out from the interface a member is DECLARED in rather than from the receiver's own folded type. The comment says what the control cannot do, too: it cannot catch "member owner passed instead of folded type" in TypeScript, because an implementing class always declares the member itself, so the MRO walk never settles on the interface's bodiless declaration. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NdZtWXQJUGB1ZGLH2YNw3o * docs(scope-resolution): correct four overclaims the review found (#2832) A multi-lane review of this PR reproduced, against the real pipeline, that several claims in the comments and one test name assert more than the code delivers. No behavior changes here — only the text, and one test rename. 1. The test comment gave the WRONG REASON why the concrete-implementor control cannot catch "member owner passed instead of folded type". It said an implementing class always declares the member itself; `class C extends Base implements I {}` is valid TypeScript and inherits it. The real reason is that TypeScript's MRO chain never contains an implemented interface, so the walk cannot settle on an interface declaration for a concrete receiver. The mutation IS expressible where a concrete class inherits a `default` interface method (Java, Kotlin) — reproduced during review — so this is language-scoped, not inherent, and a follow-up fixture is tracked. 2. "fans out to every implementation of the folded interface" certified a completeness that does not exist. TypeScript emits heritage edges for `class_declaration` only (languages/typescript/captures.ts:749, stated in its own docstring at :732-733), so `abstract class X implements I` and `interface B extends A` produce no heritage edge and still dead-end on the bodiless declaration. Renamed to name the shape actually covered, with a KNOWN GAP note. The gap is in the capture layer and predates this fan-out. 3. Invariant I4 said Case 0.5 is the ONLY case that resolves a receiver type without fanning out. Cases 3 and 5 do too, by direct lookup rather than a fold or MRO walk. The sentence now says which distinction it means and states the reachability argument (no known language reaches Case 3 with an Interface — every one that could strips the namespace qualifier first, sending it to Case 4) instead of implying a completed audit. 4. The gate's rationale claimed the `ownerDef.type !== 'Interface'` test is right for every non-Interface receiver. An abstract-class receiver also dead-ends on a declaration-only member and does not fan out. Noted, with why widening the gate belongs to Cases 0 and 4 across all languages rather than to #2832. Also completes the module-level case ladder, which still credited the fan-out to Case 0 alone and omitted it from the Case 3b entry.

It is excluded for a different reason than 3 and 5 — its receiver IS the type name, so the site is static dispatch and a fan-out would be wrong, whereas 3 and 5 resolve by direct lookup rather than a fold or MRO walk. Say both rather than enumerate one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NdZtWXQJUGB1ZGLH2YNw3o * fix(scope-resolution): close the two gaps the #2842 review left open Both were pre-existing and reached by Cases 0 and 4 as well; the Case 3b fan-out only widened the population of sites that hit them. Researched against the real TypeScript compiler and the language service before choosing semantics, plus how comparable tools draw the same lines. 1. THE FAN-OUT COULD TARGET A STATIC MEMBER `class C implements I { static save() {} }` does not satisfy `I` — TypeScript rejects it as TS2420, "Property 'save' is missing" — so an edge from an `I`-typed receiver to a static member names a target dispatch can never produce. The closure picked targets with `pickOverload`, which applies no static filter, while the surrounding cases pick their own primary with `pickFirstNonStaticOnly`: the speculative edges were picked with weaker rules than the certain edge they hang off. A same-name static+instance pair also made `pickOverload` return OVERLOAD_AMBIGUOUS, suppressing the CORRECT edge too, so this was a false negative as well as a false positive. Every comparable tool draws this line: tsserver partitions static from instance results, clangd gates on `isVirtual()` (C++ forbids virtual statics), jdtls filters abstract-or-static, and class-hierarchy analysis expands only VIRTUAL call sites. The guard prefers `provider.isStaticOnly` where a language declares it and falls back to the graph node's `isStatic`. That order is load-bearing, not stylistic: the method extractor derives `isStatic` from the OWNER type as well as the member (`staticOwnerTypes`), and the JVM config lists `object_declaration` — so reading the flag first would delete Kotlin `object` implementations, which are singleton INSTANCES and genuinely reachable. Kotlin is the only hook implementor and marks exactly the companion-promoted set; Ruby's `singleton_class` (`def self.foo`) is correctly filtered by the fallback. 2. TYPESCRIPT HERITAGE WAS CLASS-ONLY `interface B extends A` and `abstract class X implements I` emitted no heritage edge at all, so the subtype closure had nothing to descend and both shapes dead-ended on a bodiless declaration — including the very example the closure's own docstring cites as the reason it exists. Since Case 3b's dotted-alias binding survives qualifier-stripping only in TS/JS, this was the language that actually reaches the new path. The two shapes reach their bases differently: an abstract class carries the same `class_heritage` child a concrete one does, while an interface's bases hang off `extends_type_clause` directly. That clause's `type` field is `multiple: true`, so `childForFieldName('type')` would silently drop `C` from `interface B extends A, C` — hence iterating named children. Deliberately NOT structural matching. TypeScript is structurally typed, so a class satisfies an interface without `implements`, but tsc's own navigation is declaration-only and says why: "users are typically only interested in explicit implementations... The type checker doesn't let us make the distinction between structurally compatible implementations and explicit implementations, so we must use the AST." scip-typescript reached the same design independently. gopls does match structurally, but only because Go has no `implements` keyword to prefer. Abstract declarations are still walked THROUGH rather than targeted — the rule everywhere is "does it have a body?", which is what `isDeclarationOnly` already tests. VERSIONING. The capture change is parse-time, so a v43 warm cache would serve entries missing the new matches: SCHEMA_BUMP 43 -> 44 with its pin test moved in the same commit, verified against origin/main at a857f4c5a (still 43). Rebaselined only the `typescript` scope-capture fingerprint, justified by a capture-name histogram diff over the same 145-file corpus: the only deltas are @reference.inherits 17 -> 20 and its paired @reference.name 245 -> 248, emitted together by `emitTsInheritanceBase`. Every other capture count is byte-identical and javascript is unchanged, the language having no interfaces. Tests: the fan-out now covers a static-shadowing subclass, a concrete class below an abstract intermediate, and an implementor of an extending interface. Resolvers 3176 passed; all five bench gates pass.

Gergő Magyar	cabd5b82f9	fix(go): model Go method sets exactly so interface satisfaction is decidable (#2813) (#2829) ... * test(go): pin calls through an interface-typed struct field (#2813) A call through an interface-typed struct field never reaches the implementation: the CALLS edge stops at the interface DECLARATION, so `impact()` on the implementing method reports 0 callers. This commit adds the executable statement of that defect; the fixes follow. Two stacked defects produce it, and either alone is enough to reproduce — which is why no existing fixture could observe it: D1 `buildDetectionIndexes` skips every POINTER-receiver method, so a struct whose methods are all `func (r *T)` has an empty method set, structurally satisfies nothing, and gets no IMPLEMENTS edge. Go's rule is that the method set of *T includes pointer-receiver methods, and idiomatic Go stores *T in an interface-typed field. D2 Case 0 (compound receiver) emits its primary edge and short-circuits without the interface-dispatch fan-out Case 4 performs. A struct field receiver `s.orderRepo` contains a dot and so always takes Case 0; a local or parameter receiver is a bare name and reaches Case 4. Every implementor in both pre-existing structural-dispatch fixtures uses a VALUE receiver, and the one pointer-receiver type is pinned as a negative (`not.toContain('PointerOnlyThing -> PointerOnly')`), so the corpus could not see D1 by construction. The new fixture is pointer-receiver throughout, cross-package, and carries concrete-field controls in the same structs. Failing-first, verified against this tree: 7 of the 11 new assertions fail and 4 pass. The 4 that pass are exactly the controls that must not regress — the primary edge to the interface declaration, the concrete-field call, the absence of fan-out on a concrete field, and the partial-signature negative — so the suite discriminates rather than merely failing. Two recorded artifacts move here because the FIXTURE was added, not because capture output changed: - test/fixtures/go-captures-golden/expected-captures.json — regenerated additively (32 insertions, 0 deletions). - bench/scope-capture/baselines.json — go fingerprint, fixture_count 102 -> 110. Both are regenerated in this commit rather than deferred to the end of the series: the fixture is their only cause, no later commit touches capture emission, so they cannot re-drift and every commit stays green. The check that this is corpus growth and not a capture regression is that go was the only one of 15 language fingerprints to move on the same run. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(go): count pointer-receiver methods toward structural interface satisfaction (#2813) D1 of two stacked defects. `buildDetectionIndexes` skipped every method whose receiver is a pointer, so a struct declaring `func (r *OrderRepo) DeleteItem(...)` had an EMPTY method set, structurally satisfied nothing, and produced no IMPLEMENTS edge at all. Go's method-set rule is per-type, and there are two types involved: the method set of `T` holds only value-receiver methods, while the method set of `*T` holds both. #1966 implemented the `T` reading, which is exactly right for `T` — and leaves `*T` permanently empty. GitNexus models one Struct node per type with no separate `*T` node, so only one of the two can be represented, and the `T` reading is the one idiomatic Go almost never uses: methods take pointer receivers so they can mutate, and `*T` is what gets stored in an interface-typed field. The cost was silence rather than caution. With no IMPLEMENTS edge, a call through an interface-typed field resolved to the interface DECLARATION and `impact()` on the implementing method returned 0 callers — byte-identical to a symbol that genuinely has none, which is what made the reporter's blast-radius check unusable rather than merely incomplete. This picks the `*T` reading: the graph now answers "which types provide this interface's behaviour", and no longer proves `var x I = T{}` invalid. The trade is deliberate and was checked against every consumer of IMPLEMENTS before being made — MRO/METHOD_IMPLEMENTS derivation, community clustering, the receiver-dispatch fan-out index, and the epistemic heritage probe. None performs value-assignability checking. Two negative pins encoded the #1966 decision and are REVERSED here rather than deleted, each keeping a comment that explains why the polarity moved: - go.test.ts: `PointerOnlyThing -> PointerOnly` now expected to be emitted. - go-hooks.test.ts: the pointer-receiver-only unit case now expects the implementor instead of `undefined`. `goReceiverKind` is still stamped in method-owners.ts — it is the hook a future value/pointer-aware model would read — but is deliberately no longer a filter. Its now-dead local predicate and type alias are removed so the file no longer carries a helper asserting the reverted rule. Measured on the #2813 fixture, this commit alone: the two IMPLEMENTS assertions flip to passing (6 pass, up from 4) while the five interface-dispatch fan-out assertions still fail — those are D2, fixed in the next commit. Keeping the two commits separate is what makes that attribution visible. Go unit suite: 91 passed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(resolution): fan out interface dispatch from a compound receiver (#2813) D2 of two stacked defects, and the one that closes the issue. Case 0 (compound receiver) emitted its primary edge and short-circuited without the interface-dispatch fan-out that Case 4 performs, so a call whose receiver is a struct FIELD stopped at the interface's method DECLARATION and never reached any implementation. The gap was a property of receiver SYNTAX rather than of types. Case 0 is selected by `receiverName.includes('.')`, so a field receiver (`s.orderRepo`) always lands there, while the very same interface reached through a local or a parameter is a bare name and falls through to Case 4 — which fans out correctly. Field-held interfaces, i.e. dependency injection, were the half that silently lost every implementation edge; the pre-existing fixtures exercise the local and parameter forms only, which is why the suite was green. The fix is the call Case 4 already makes, placed after Case 0's primary `tryEmitEdge` and before its `handledSites.add`. It stays language-agnostic (AGENTS.md section 42): `emitInterfaceDispatchFor` self-gates on `ownerDef.type !== 'Interface'`, so a receiver that folds to a Struct emits nothing extra and no language check is needed. Confidence is Case 0's own 0.85 literal, not Case 4's site.kind-dependent value — Case 0 has no read/write arm to mirror. The case ladder itself is untouched: invariant I4 in contract/scope-resolver.ts makes the ordering a contract, so the fan-out is added INSIDE Case 0 rather than by reordering or merging cases. Also flips a second, previously unnoticed encoding of the #1966 value-only reading that the full sweep surfaced: the exact-set assertion at go.test.ts:361 enumerates every structural IMPLEMENTS edge, and D1 correctly adds `PointerOnlyThing -> PointerOnly` to it. It is D1 fallout rather than D2's, but D1 had already landed; recording it here with its reason beats amending a commit whose separate measurability is the point. Measured: - #2813 suite: 11 of 11 pass (was 7 failing after D1 alone, which fixed only the two IMPLEMENTS rows). - go.test.ts: 160 passed. - Full cross-language sweep, test/integration/resolvers: 3027 passed, 1 skipped, across 52 files. The single failure in that run was the exact-set assertion above, fixed here; no other language regressed. `detect_changes` rates this HIGH (6 affected flows, all EmitReceiverBoundCalls at step 1) — inherent to editing a hub symbol in the resolution pipeline. The sweep above is the empirical answer to that label. An existing index must be re-analyzed to show the new edges; this changes what the resolver produces, not how it is stored, so no SCHEMA_BUMP applies. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(go): pin the heritage edges that make impact() hedge an interface-bound count (#2813) The epistemic half of the issue, resolved by MEASUREMENT rather than by new code, and pinned at its mechanism. The reporter's disqualifying complaint was that `impact()` reported `impactedCount 0, epistemic "exact", risk LOW` for a method reachable only through an interface-typed field — byte-identical to what it reports for a symbol that genuinely has no callers. A zero therefore could not be used defensively, which was the entire use case. That verdict comes from `computeEpistemicBoundary`, which has two producers and neither fired: the call sites were not DROPPED (they resolved, just to the interface declaration, so the #2744 receiver-typing producer saw nothing), and its heritage probe walks IMPLEMENTS/METHOD_IMPLEMENTS edges out of the queried symbol — of which there were none, because the pointer-receiver exclusion (D1) meant no such edge was ever emitted. Restoring those edges fixes the epistemics as a side effect, so the planned conditional change to local-backend.ts is NOT needed. Measured on this fixture against the fixed tree: impact(OrderRepo.DeleteItem, upstream) before: impactedCount 0, epistemic "exact" after: impactedCount 3, epistemic "lower-bound", with an interface boundary note; the three callers are OrderHandlers.Delete, PickService.StartSession and WaveService.Release — all correct. impact(CartRepo.Get, upstream) [concrete receiver, no interface] after: impactedCount 1, epistemic "exact" The second row is the one that matters for trust: the hedge discriminates instead of firing on everything, so "exact" still means exact. This test asserts the METHOD_IMPLEMENTS edges the probe walks. Pinning the mechanism keeps the resolver suite from reaching into the MCP layer while still failing loudly if the edges regress; the impact() numbers above are recorded in the commit message and PR body rather than re-asserted here. #2813 suite: 12 passed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(go): model Go method sets exactly so interface satisfaction is decidable (#2813) Replaces the approximate structural-interface model with the rules the Go spec actually defines, so the graph answers what the compiler answers instead of a useful-but-wrong summary of it. Three answers were provably wrong before; all three are now exact and covered. Method sets (go.dev/ref/spec#Method_sets): MS(T) = methods declared with receiver T MS(*T) = methods declared with receiver *T OR T Promotion (#Struct_types): S embeds T -> MS(S) and MS(*S) get promoted methods with receiver T; MS(*S) ALSO gets those with receiver *T S embeds *T -> MS(S) AND MS(*S) both get receiver T or *T Identifier identity (#Uniqueness_of_identifiers): "Two identifiers are different if they are spelled differently, OR IF THEY APPEAR IN DIFFERENT PACKAGES AND ARE NOT EXPORTED." func (b *Base) Ping() // pointer receiver type ByValue struct{ Base } type ByPointer struct{ *Base } type before exact answer Base IMPLEMENTS only *Base implements ByValue IMPLEMENTS only *ByValue implements ByPointer IMPLEMENTS the VALUE type implements All three were the same edge. Two of the three were wrong, and nothing in the graph could tell them apart. Worse, in a different direction: package sealed; type Sealed interface { seal() } package foreign; func (t *T) seal() {} `foreign.T` cannot implement `sealed.Sealed` in Go — `seal` is unexported, so the two identifiers are DIFFERENT. Matching on the bare name emitted a FALSE IMPLEMENTS edge, and the interface-dispatch fan-out then turned it into an impossible CALLS edge. That is the entire basis of the sealed-interface idiom. - `methodSetKey` qualifies UNEXPORTED method names with their declaring package, leaving exported names unqualified (which is what makes cross-package satisfaction work at all). Exactness, not a heuristic: the sealed case now emits no edge, while the legitimate same-package implementor is retained. - `collectStructMethodEntries` builds MS(T) and MS(*T) together and applies the promotion table above. The embed FORM is load-bearing, so it is now captured: `@reference.embedded-pointer` records `*T` versus `T`, which the parser previously discarded (the `*` is an unnamed token). - Detection returns `{ structDefId, receiverForm }`. `receiverForm: 'pointer'` means the value type does NOT implement and only `*T` does — the fact `var x I = T{}` turns on. - The form rides in the edge `reason` (`-structural-implements-pointer`). Relationships carry no arbitrary properties, so a new field would change the relation DDL, move SCHEMA_FINGERPRINT and force a rebuild for a fact a string already expresses. Value-form implementors keep the ORIGINAL unsuffixed reason, so a consumer matching the old string now sees exactly the assignable set — which is what that string always claimed to mean. - `emitInterfaceDispatchFor` walks the SUBTYPE CLOSURE (IMPLEMENTS + EXTENDS) and skips bodiless declarations, instead of stopping at depth 1. Two reproduced Java shapes emitted an edge to a second abstract declaration while the only class with a body got nothing: a sub-interface that re-declares the method, and an abstract base between interface and implementation. Both now reach the implementation and neither emits the declaration edge. - The fan-out is bounded by `MAX_INTERFACE_DISPATCH_FANOUT` (32, `GITNEXUS_MAX_INTERFACE_DISPATCH_FANOUT`) and reports what it dropped, mirroring `MAX_PROPERTY_DISPATCH_FANOUT`. A bare cap would silently discard valid dispatch targets, which is the same false-safe silence this issue is about. - Corrects a rationale comment that was factually wrong about the code 70 lines above it (Case 0 DOES branch on `site.kind`, at :713-716; what it lacks is a read/write branch in its reason/confidence computation). - Updates both copies of the case-ladder contract, which still described the fan-out as Case-4-exclusive. The embed-pointer marker is PARSE-TIME capture emission, so a warm cache would replay the pre-marker capture set and the distinction would never appear — silently, the v27/v30 failure mode. 43 and not 40 because origin/main allocated 40, 41 and 42 while this branch was in review, which is exactly the window this file's history records both prior EXACT clashes landing in. Pin moved with it. RE-CHECK AGAINST origin/main IMMEDIATELY BEFORE MERGE. - Go unit: 93 passed, including new rows pinning that `populateGoOwners` stamps `goReceiverKind` (previously the field had no reader and could rot silently) and that a pointer-receiver-only type implements in POINTER form only. - Cross-language sweep, test/integration/resolvers: 3034 passed, 1 skipped, 52 files, zero regressions. - scope-capture bench: PASS (15 languages). Go is the ONLY fingerprint that moved, which is the check that this is a Go capture change and not a cross-language regression; rebaselined with rationale. - Also closes review gaps in this PR's own tests: the concrete-field control was vacuous with respect to the type gate (repointed at a struct that IS an implementor), the two-service-file row could not distinguish the two files it is named for (both ends now file-qualified), plus new rows for signature mismatch, emitted confidence, and an exact N-by-M fan-out bound. An existing index must be re-analyzed; the schema bump forces it.

Gergő Magyar	c1103f38f2	fix: type an inference-typed class field so it can act as a call receiver (#2807) (#2810) ... * test(helpers): add the shared temp-repo lifecycle helper `createTempDirPool` gives a suite one owner for its temp fixture repos — create on demand, remove them all in one `afterAll` — instead of a hand-rolled mkdtemp/rmSync pair per file. The PDG receiver pin added in the next commit uses it. Cherry-picked verbatim from ec36c6dda on the #2802 branch, where it was extracted to collapse five hand-rolled cleanups. Identical content, so if both branches land the add resolves as a duplicate rather than a divergence. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(typescript): type a class field from its initializer so it can be a receiver A field whose type had to be inferred from its initializer produced no CALLS edge at all — not a truncated chain, nothing. `this.p.inner().compute(x)` lost `Outer.inner` too, an ordinary named-receiver call, because `typeOfMemberOnClass` found no `typeBindings` entry for `p` and `foldReceiverChain` declines at its first untypeable step rather than folding on a guessed owner. The initializer was never invisible: `new Outer()` emitted its own constructor edge exactly as the annotated twin does. What was missing was the step turning that initializer into a TYPE BINDING, i.e. capture patterns for the two shapes the query never covered: private p = new Outer(); // public_field_definition value: private p; constructor() { this.p = new … } // this.<field> = new … Both are `@type-binding.constructor`, so `annotation` still outranks them in `typeBindingStrength` and an annotated field keeps resolving through its annotation. The assignment form carries a narrow `@type-binding.this-field` marker on its `(this)` node — anchorCaptureFor takes the broadest range, so the statement stays the anchor — which `tsBindingScopeFor` reads to hoist the binding onto the Class scope, the only place `typeOfMemberOnClass` looks. The marker must stay specific to that pattern: hoisting every constructor-inferred binding would move method-local `const o = new Outer()` out of its own scope. Kotlin and Swift needed no such pattern for the initializer form because one grammar node (property_declaration) covers both a local and a stored property; TypeScript splits them, and only the local half was ever covered. Both self-diffing pins flip and gain rows: a method-assigned field, and a deliberately mistyped `private p: Mismatch = new Outer()` that asserts the source-strength tie-break executably. That row also pins a pre-existing artifact — `Inner.compute` still resolves through the hoisted module-level return-type binding — verified byte-identical on the pre-fix tree. Fixes #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(javascript): type a class field from its initializer so it can be a receiver JavaScript has no field annotations at all, so a class field's type can only ever come from its initializer — which made this the strictly worse half of #2807: `class C { p = new Outer(); }` gave `this.p` no type, and `this.p.inner()` emitted nothing. `synthesizeConstructorFieldBindings` in captures.ts already covered the sibling shape, `this.p = new Outer()`, which is why THAT row resolved — but it only walks `constructor` bodies, so a field initialized at its declaration matched no pattern anywhere. Adds the `field_definition` + `value: (new_expression)` patterns (the JS grammar names the field `property:`, not `name:`), anchored so the binding lands in the class body scope where `typeOfMemberOnClass` reads it. No hook change needed: `jsBindingScopeFor` already delegates to `tsBindingScopeFor`, so it inherits the `@type-binding.this-field` branch too. Measured: `InferredField.run` now emits `Outer.inner`, exact parity with both the local-const control and the constructor-assigned row. The second chain link (`Inner.compute`) stays absent in ALL THREE rows — that is JavaScript's separate return-type-inference gap, not this one. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(python): infer an instance field's type from the constructor it calls `self.outer = Outer()` in `__init__` bound nothing, so `self.outer.inner()` had no receiver type and the fold declined the whole chain — the Python half of #2807. An annotated field (`self.outer: Outer = ...`) or one assigned from an annotated parameter already worked. `synthesizeConstructorFieldTypeBindings` deliberately refused to infer "from arbitrary unannotated RHS expressions ... not a name-only guess". A CALL is not that: Python has no `new`, so a call to a plain (or dotted) name is the only syntactic construction form there is, and it is the same positive evidence every other language reads from `= new X()`. A bare name, subscript, await or comprehension is still refused. Adds it as a THIRD and weakest tier. The existing explicit/parameter boolean becomes a rank, so precedence is now explicit annotation > parameter annotation > construction, and a later same-tier assignment still wins (the last write in `__init__` is the live one). `interpretPythonTypeBinding` maps the new marker to `constructor-inferred` (strength 1) — checked before the parameter branch, which would otherwise have read the absent parameter marker as `annotation` and promoted a guess to the strongest tier. The Class-scope hoist needed no change: `@type-binding.instance-field` already carries it in `pythonBindingScopeFor`. Measured: `AssignedField.run` now emits `Outer.inner`, exact parity with the annotated-field and local-const rows. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(ruby): infer an instance variable's type from the constructor it calls `@service = UserService.new` in `initialize` bound nothing, so `@service.inner` had no receiver type and the fold declined the whole chain — the Ruby half of #2807. An instance variable is the ONLY way a Ruby object gets a field, and Ruby has no annotations, so this was the single shape that could have worked and did not: the existing constructor-inferred patterns bind a local (`x = Foo.new`) and a constant (`SERVICE = Foo.new`), never an ivar. Adds the plain and `Foo::Bar` qualified ivar forms. `@type-binding.name` is captured on the `instance_variable` node so the bound name keeps its `@` sigil and matches the receiver text at the call site verbatim — the resolver compares spellings, and `service` would never have matched `@service`. `rubyBindingScopeFor` gains a Class hoist gated on a narrow `@type-binding.ivar-field` marker riding the same node: an ivar declares a field of the enclosing class, so the binding must live on the Class scope or no other method can see it. Gated on the dedicated marker, never on `@type-binding.constructor` at large, which also fires for `x = Foo.new` locals that must stay in their own method. Measured: `AssignedField.run` now emits BOTH chain links, exact parity with the local-const control. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(resolvers): pin inference-typed field receivers across eight languages #2807 was filed against TypeScript, but the defect class is cross-language: "can a field whose type is inferred act as a call receiver". This measures all eight languages where the shape exists at all, in one table. The metric is parity with EACH LANGUAGE'S OWN CONTROL ROW, not "both chain links present". JavaScript, Python, Dart and PHP lose the second link (`Inner.compute`) even for a plain local, because nothing annotates `inner()`'s return type — a separate return-type-inference gap. Scoring against "both links" would have accused those four of a bug they do not have; scoring against their own control isolates the field-typing question cleanly. Recorded state: TypeScript, JavaScript, Python and Ruby now match their controls. Kotlin and PHP already did before #2807 and are pinned so the shared fold cannot regress them unnoticed — the languages that got receiver typing for free are precisely the ones nobody re-checks. Two rows stay pinned BROKEN, at their exact current value: Dart — real and narrow: the annotated control resolves, the inferred one does not. Its bindings are synthesized in dart/captures.ts rather than by a query, so the fix is its own change. Swift — blocked by a different defect found while measuring: with several classes each defining `run`, every `run`'s edges are attributed to the FIRST-declared one, which collects duplicates while its siblings — including the ANNOTATED control — collect none. Receiver typing cannot be measured there until that is fixed, and "fixing" it against this observable would be fitting to a broken measurement. Both gap rows carry a `callerExists` probe in the same assertion object, so an empty list can never read as "resolved fine, wrong node id", plus a whole-matrix guard that every language keeps a resolving control — that is what makes a gap row mean "broken" instead of "fixture never worked". Targets are deduplicated before comparison: Swift emits one edge more than once per call site, and edge multiplicity is a different question from whether the receiver typed at all. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(python): a method call on the receiver is not a construction Review finding on f4e1ead0d. `constructorCallTypeName` accepted ANY call with an identifier or attribute callee, so `self.p = self.build()` bound `p` to the non-type `"self.build"` — and because that shares the weakest tier with a real construction, a later such assignment DISPLACED an earlier `self.p = Outer()` and left the field untyped again. Measured before the fix: `self.p = Outer()` followed by `self.p = self.rebuild()` emitted no CALLS edge at all from a method chaining off `self.p`, and `self.q = self.make()` bound a type name that resolves to nothing. After: the real construction survives the reassignment, and a pure method call binds nothing rather than something wrong. Rejects a callee rooted at the receiver name. `models.Outer()` still binds — only `self`-rooted callees are refused, which is exactly the method-call shape. The matrix gains a `reassigned-from-method-call` row that fails without this rejection; that discrimination is the only reason the row exists. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(swift): resolve a method def to its own node when the labels disagree Two classes in one Swift file each declaring `func run` collapsed onto one node: every call in BOTH bodies was attributed to whichever `run` registered first, which collected duplicate edges while its twin collected none. Renaming one method fixed it; moving it to another file fixed it; so the collision was name-keyed and per-file, not positional. Root cause is a LABEL split, not a name. Swift's structure phase emits a type's methods as `Function` nodes, while the scope extractor derives `Method` from the `@declaration.method` anchor. Every key in `resolveDefGraphId` — qualified, parameter-types, arity, shape — is label-scoped, so such a pair misses all of them and lands on the bottom fallback, `simpleKey(filePath, name)`, which is deliberately label-agnostic and first-write-wins. Fixed at both ends: - Swift qualifies a method def as `<Type>.<method>`, matching the qualifier the structure phase already encoded in the node id. `class`, `struct` and `extension` all parse to `class_declaration`, so one ancestor walk covers them; a generic `class Box<T>` and an `extension Foo` wrapping a `user_type` both reduce to the bare owner name. - The bridge retries the qualified keys under the sibling callable label. Gated on the name containing a dot: `A.run` names one construct whatever the label, while a bare `run` is exactly the top-level-vs-method aliasing the label was added to prevent, so the original guarantee is untouched. This also unmasked Swift's #2807 row. `let p = Outer()` had always bound correctly — its edges were being credited to the wrong caller, so the inference-typed receiver looked broken when it was not. `InferredField.run` now emits `Outer.inner`, matching its control. Verified on the full resolver + CFG suite: 3165 passed, 0 failed, against a 3164-passing baseline. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(dart): declare inference-typed class fields so they can be receivers `var b = Outer();` produced no `@declaration.property` capture at all — no Property node, and nothing for the capture layer to hang a type binding on — so `b.inner()` could not type its receiver while the annotated twin `Outer b = Outer();` resolved fine (#2807). The gap was in the query, one layer below where the binding is emitted: both class-field patterns require a leading `(type_identifier)` or `(nullable_type)`, i.e. a WRITTEN type. Dart puts the keyword there instead for an inferred field, and spells it two ways — `inferred_type` for `var`, `final_builtin` for `final` and `late final`. Covering only `var` would have left the more idiomatic Dart style broken, so both are matched. With the field declared, the capture layer types it from the constructor its initializer calls, as `constructor-inferred` — the weakest source, and the annotated branch returns before it, so an annotated field is untouched. Only a direct construction is accepted (a bare identifier followed by a `selector` carrying an `argument_part`, the same shape `findDirectCallValue` accepts for locals); a literal, member call or await is left alone rather than guessed at. Note this is the LOCAL/field split that made the gap invisible: `emitVarTypeBinding` already handled `initialized_variable_definition`, but a class field is `declaration(<keyword>, initialized_identifier_list(initialized_identifier))`. `InferredField.run` now emits `Outer.inner`, matching its control. Dart's `var r; C() { r = Outer(); }` shape stays pinned as a known gap: Dart writes the field with no receiver prefix, so binding it means treating assignment to a bare identifier as a field write, indistinguishable from a constructor-local. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(resolvers): record Swift and Dart reaching parity in the matrix Both languages' inference-typed field rows move from KNOWN GAP to resolving, which is the self-diffing signal this file was built to produce: closing either gap failed it with the newly resolved ids in the diff. The header table and prose are corrected together with the rows, as the file's own instructions require — including WHY Swift moved. Its `let p = Outer()` binding had always been correct; a separate label-split defect attributed the second same-named method's calls to the first, which masked this row entirely. Recording that is the point: a future reader comparing the table against the code needs to know the row was never a receiver-typing failure. One row stays pinned: Dart's `var r; C() { r = Outer(); }`. Dart writes fields without a receiver prefix, so binding it means treating assignment to a bare identifier as a field write — indistinguishable from a constructor-local until the field set is known. Idiomatic Dart writes `final r = Outer();`, which the inferred-field row now covers. Every language keeps its resolving control row, so the remaining gap still means "broken" rather than "fixture never worked". Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(dart): type a field from a constructor assigned to it `var r; C() { r = Outer(); }` bound nothing, so `r.inner()` had no receiver type — the last inference-typed field shape still failing after the initializer form was fixed (#2807). Dart is the one language here that writes a field with NO receiver prefix, so `r = Outer()` inside a constructor is syntactically identical to assigning a constructor-local. That ambiguity is why this was initially left pinned — but the field set IS knowable: the class body declares `var r`, which the initializer fix already turned into a property declaration. So a bare name binds exactly when Dart itself resolves it to the field: the enclosing class declares it AND the enclosing body declares no local of that name. A `this.`-prefixed write is unambiguous and needs neither test. The shadowing case is asserted, not assumed: with a body-local `var s = Outer()` in scope, the field stays unbound while the local still resolves on its own. Binds `constructor-inferred` (weakest source, so an annotation still wins), and only for a direct construction — an identifier followed by a `selector` carrying an `argument_part`, the same shape accepted for locals. The narrow `@type-binding.dart-field` marker drives the Class-scope hoist in `dartBindingScopeFor`; gating on it rather than on `@type-binding.constructor` at large is what keeps genuine locals in their own scope. All three shapes now match their control: bare `r = Outer()`, `this.s = …`, and a non-constructor `setUp()` assignment. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(swift): type an optional field and read through its force-unwrap Swift cannot declare a stored property with neither a type nor an initializer, so its "declare now, assign in init" idiom is an OPTIONAL field read back through a force-unwrap. That shape resolved nothing, and it was broken in two independent places — each alone leaves it broken: 1. `var a: Outer?` parses as `type_annotation(optional_type(user_type(…)))`, but the property-annotation pattern required the `user_type` to be a DIRECT child, so an optional field was never typed at all. The pattern added here captures the INNER `type_identifier`, so the binding is `Outer` without relying on `stripOptional` reducing an `Outer?` spelling. 2. `self.a!` is a `postfix_expression`, which the receiver walk did not peel, so even a typed field could not be read through the unwrap. For (2), `postfix_expression` is NOT added to `TRANSPARENT_RECEIVER_WRAPPERS` outright: unlike TypeScript's `non_null_expression` — which is only ever `!` — Swift's node also carries user-defined postfix operators, which can return anything. Peeling those would type the receiver as the operand and mint a confidently WRONG owner, the failure mode compound-receiver.ts calls strictly worse than no edge. So the peel is operator-gated: transparent only when the node's text ends in `!`, which is provably type-preserving. Verified: force-unwrap `self.a!.inner()`, optional chain `self.b?.inner()`, and the plain annotated field all resolve; previously only the plain one did. The gate keeps this off every other language — `postfix_expression` is not a node type the other grammars produce here — and the full resolver + CFG suite is green at 3166 passed / 0 failed, against a 3165 baseline. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(resolvers): close the last two matrix gaps Dart's `assigned-field` and Swift's new `optional-assigned-field` rows now resolve, leaving no known-gap row in the matrix: every language reaches parity with its own control on both the initializer and the assigned shape it can express. The Swift row is new because the shape it covers did not exist in the fixture: Swift cannot declare a stored property with neither type nor initializer, so its assigned form is an optional field written in `init` and read through a force-unwrap — a shape that needed both an optional-annotation pattern and an operator-gated receiver peel, which is why the row's comment names both. The header records how the two hard cases were fixed, including the Dart shadowing rule the fix depends on: a bare `r = Outer()` binds only when the class declares that field and the body declares no local of the same name. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * chore(bench): rebaseline the receiver-resolution and scope-capture gates Both gates are exact-match, so the improvements in this branch fail CI until the baselines move and the movement is explained. Caught by running the CI gates locally — the resolver and CFG suites are green throughout and never see these. receiver-resolution — three shapes moved to RESOLVES, no drop-count changed: ruby.fieldReceiverCall INVISIBLE-GAP -> RESOLVES (`@ivar = Foo.new`) swift.decoratedFieldType INVISIBLE-GAP -> RESOLVES (`var a: Outer?`) kotlin.nonNullAssert VISIBLE-GAP -> RESOLVES (`x!!` receiver) scope-capture — swift and typescript fingerprints, both ADD captures and remove none; the per-language `_rebaselined_inferred_field_receiver_2807` notes carry the detail and the prior digests. The other 13 languages are unchanged, which is the check that this is the intended emission and not a capture regression. CORRECTION to d5d878033's message, which claimed the operator-gated `postfix_expression` peel "keeps this off every other language — postfix_expression is not a node type the other grammars produce here". That is wrong: Kotlin's grammar produces it too, and `kotlin.nonNullAssert` moving to RESOLVES is the proof. The peel is still correct there — Kotlin `!!` is a non-null assertion with exactly the type-preserving semantics the `!` gate tests for — but it is a BEHAVIOUR CHANGE IN KOTLIN, not Swift-only as stated. The gate is what surfaced it; the claim should have been verified rather than asserted. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(cache): bump SCHEMA_BUMP for the six-language capture change, + review fixes SCHEMA_BUMP 39 -> 40. THIS IS THE MERGE-BLOCKER of the review: every language change in this PR is PARSE-TIME capture emission, and `analyze` skips tree-sitter dispatch for byte-unchanged chunks (GUARDRAILS.md:34), so a warm cache replays the pre-fix capture set verbatim and the new receiver edges never appear — silently, no error. Exactly the v27/v30 failure mode this file already documents. The PR description's claim that "no schema or version constant applies" was wrong on both counts: a bump IS required, and a plain re-analyze does NOT surface the captures without it. Re-check against origin/main before merging — main was also at 39 when 40 was allocated, and this file records eight prior collisions. Also from the review: - dart/simple-hooks.ts hand-rolled a 9-line parent walk byte-identical to the shared `walkToScope(innermost, tree, 'Class')` that TypeScript and Ruby call in one line in this same PR. Now uses the helper. - utils/call-analysis.ts: the doc framed the postfix-`!` peel as Swift-only. It is not — Kotlin `!!` parses as the same node and is peeled too, which the receiver-resolution bench proved (kotlin.nonNullAssert VISIBLE-GAP -> RESOLVES). The comment now says so, and names the `!` gate rather than the language as the bound. - test/helpers/temp-dir-pool.ts: its doc claimed four consumers; on THIS branch only `pdg-chained-receiver-callees` uses it (the other three convert on #2802). Corrected, and the byte-identical-to-#2802 intent recorded. - inferred-field-receiver-matrix: adds the Dart shadowing assertion the header comment already CLAIMED to make but never did. First attempt was vacuous — `var s = Outer()` is a declaration, so it never produced the bare `assignment_expression` the guard inspects; removing the guard did not fail the row. Fixture corrected to `var s; s = Outer();`, and mutation-verified: guard present 35 pass, guard removed the row goes red. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(cache): move the SCHEMA_BUMP pin to 40 The pin at incremental-parse-cache.test.ts asserts the exact value on purpose — it exists to catch two branches claiming one number, and it has earned that eight times. Bumping the constant to 40 without moving the pin turned it red. Found by the Codex (gpt-5.6-sol) review leg, which flagged it as a deterministic committed-test failure. The Claude lanes could not have caught it: they were dispatched before the bump landed. The comment now records the 39 -> 40 movement and its reason, matching the existing convention in that block. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(dart): treat every binder as a field shadow, not just local declarations Review P1, reproduced by two independent reviewers. `emitDartFieldAssignmentBindings` binds a bare `r = Outer()` to the FIELD when the class declares `r` and the body declares no local `r` — but the shadow set was built by walking for `initialized_variable_definition` only. That is one binder form out of many, so a formal PARAMETER named like a field slipped through: void reset(Alpha r) { r = Alpha(); } // r is the PARAMETER retyped the FIELD to `Alpha`, fabricating an edge AND destroying the correct `Beta` binding the constructor had established. The mutation test shows exactly that: the pre-fix result is not a missing edge but a WRONG one (`Other.inner#0` instead of `Outer.inner#0`) — the failure mode compound-receiver.ts:519-537 calls strictly worse than no edge. The node types were chosen from real grammar output, not assumed. Two facts drove the design: formal parameters live on the SIBLING `method_signature`, never inside `function_body`, so no walk of the body could ever have seen them; and `formal_parameter` carries a `name` field only when typed — untyped, `this.` and `super.` forms do not. `collectDartBodyShadows` therefore walks the signature AND the body, collecting formal/closure/local-function/named/optional params, `this.`/`super.` constructor params, catch bindings, for-in variables, and both local-declarator forms. A parameter shape whose name cannot be read contributes nothing — declining to bind is the safe direction. A 27-case binder sweep passes: 26 shadow shapes bind nothing, the no-binder control still binds. Four new matrix rows (param, closure param, catch, loop var) assert a surviving POSITIVE target rather than an empty list — deliberately, because the pre-fix value is a different non-empty target, so these rows cannot pass vacuously the way an empty-assert row can. Mutation-verified: reverting captures.ts turns exactly those four red and leaves every pre-existing row green. SCHEMA_BUMP is already at 40 on this branch for the six-language capture change and has not shipped, so it covers this too; re-check against origin/main before merge. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(ruby): don't bind a class-object @ivar as an instance field Review P1. The `@ivar = Foo.new` patterns added on this branch hoist to the enclosing Class scope without asking WHOSE `self` owns the ivar. In Ruby an ivar written in singleton context belongs to the class object, not to instances, so def self.build; @pool = Alpha.new; end class << self; def make; @cache = Alpha.new; end; end bound `@pool`/`@cache` as INSTANCE fields, fabricating edges from instance methods that read an ivar which is never assigned on an instance. Three corrections came out of fixing it: 1. The detection premise was wrong. `def self.build` is NOT a `method` node with a `self` receiver — it is its own node type, `singleton_method`, and `childForFieldName('receiver')` returns NONE on it. Matching on a receiver field would have detected nothing, silently. Detection is by node type: `singleton_method` / `singleton_class`. 2. A THIRD form exists that the review did not name: a class-body-level `class C; @shared = Outer.new;` is the same defect (self is the class object), and is likewise new on this branch — before it, `left: (instance_variable)` matched nothing at all. 3. Dropping only the `@type-binding.ivar-field` marker is NOT sufficient, and the class-body case is what proves it: with the marker gone the binding falls back to its innermost scope, which at class-body level ALREADY IS the Class scope, so it still lands in the wrong place. The whole match is therefore discarded. The check lives in `languages/ruby/captures.ts` because `Capture` carries only `{name, range, text}` — no AST node — so `rubyBindingScopeFor` structurally cannot ask whose `self` owns the ivar. All Ruby logic stays under `languages/ruby/`. `method` alone is not a sufficient "instance" signal, since a `def` inside `class << self` is reached through a `method` node first. Cost relative to main is zero: a class-object ivar goes back to binding nothing, exactly as before these patterns existed. The three new rows are structurally two-sided, not just mutation-checked: each empty row is paired with a non-empty `*-instance-ivar` row on the SAME fixture class, so breaking the hoist entirely turns the partner red while an unconditional hoist turns the empty row red. Mutation-verified in both directions. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(typescript,javascript): bind `this.field = new X()` only inside a class method Review P0, the most serious finding of the tri-review and reproduced by two independent reviewers. The `this.<field> = new X()` patterns added on this branch were CONTEXT-FREE: they matched anywhere in the file, and `tsBindingScopeFor` hoisted to the nearest enclosing Class without asking whose `this` that was. Since the binding lands on the same Class scope with the same `constructor-inferred` source as the field-initializer pattern, and pass4CollectTypeBindings prefers the later match on `>=`, it OVERWROTE the class's real field type. Reproduced from a non-arrow callback, an object-literal method, a static method, and module level. Fixed STRUCTURALLY, in the query: both patterns are now nested under `class_body -> method_definition -> body: (statement_block) -> (expression_statement)`, which kills the callback, object-literal and top-level triggers with no runtime code and mirrors JavaScript's `synthesizeConstructorFieldBindings` discipline. TypeScript still accepts ANY method, not just `constructor`, so the setter case this branch deliberately supports keeps working. `static` needed one emit-side guard: it is an ANONYMOUS token on `method_definition` with no field name, and tree-sitter patterns cannot negate an anonymous token (checked against node-types.json), so `isStaticMethodThis` drops it in captures.ts. `simple-hooks.ts` is comment-only — the unconditional Class hoist is now documented as safe BECAUSE the marker's producers are bounded, with a note that widening them means re-establishing that. Also fixes a `.ts`/`.js` disagreement the narrowing itself created: JavaScript's synthesis matched `method_definition` ANYWHERE, so an object literal containing a method named `constructor` still typed the enclosing class's field. Measured on identical source — JS emitted `p -> Alien`, narrowed TS emitted nothing — and closed with a `node.parent?.type !== 'class_body'` guard in javascript/captures.ts. The two languages must not disagree about the same source. Deliberately NOT matched (a missing binding, never a wrong one — JS declines these too): an assignment in a nested block, or inside an arrow where `this` genuinely IS the instance. Evidence the narrowing removed nothing legitimate: `bench/scope-capture --check` passes with the TypeScript AND JavaScript fingerprints BYTE-IDENTICAL. The five new matrix rows use an `Alien` class that also declares `inner()`, so a regression SWAPS the target rather than emptying the set — they cannot pass vacuously. Mutation test: reverting the source turns exactly those rows red (`+ "Alien.inner#0"`, `- "Outer.inner#0"`). SCHEMA_BUMP stays at 40 — this PR's existing bump covers the capture change being narrowed, and the buggy variant never shipped outside this branch. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(resolution): consult the sibling callable label in the position key too Review P1. This branch added a sibling Method<->Function retry to the qualified keys in `resolveDefGraphId`, but not to the #2699 POSITION key or its fail-closed guard, which both stayed scoped to `def.type`. Since the premise of the whole fix is that Swift defs are `Method` while nodes are `Function`, the position lookup missed and the fail-closed guard could NEVER FIRE for exactly the case the retry serves — so a function-local `func helper` inside `Host.run` was deterministically aliased onto the class method `Host.helper`, even with differing arity. Two earlier reviewers REFUTED this by arguing the guard runs before `lookupTagged`. That is true and irrelevant: the guard is scoped to `def.type`, so in the label-split case it is unreachable. Recording it because two independent lanes agreeing on a refutation is not proof. `siblingCallableLabel(label)` is now the single definition, consulted by all three key families: - position key: retried under the sibling label, gated on `posHit === undefined` so an AMBIGUOUS_POSITION tombstone still falls through to the name keys rather than being resolved by relabelling. Deliberately NOT dot-gated — a position key is not a name, so the aliasing risk the dot gate exists for does not apply. - fail-closed guard: mirrored unconditionally (it only ever returns undefined). - qualified retry: dot gate untouched. Measured before -> after on a Swift fixture: `Host.helper#1 -> sink` (the local body's call credited to the public 1-arg method) becomes `Host.run.helper@8:8#2 -> sink`, with the local's own node no longer edgeless. SCOPE CORRECTION to the P1 report: only the first consequence is a bridge defect. The second — "`run`'s call to the local resolves to the method" — is NOT reachable from ids.ts. Both defs carry qualifiedName `Host.helper` and label `Method`, and the binding hands the target side the class-member def, so the scope walk in free-call-fallback picks the member. No def->node mapping can change that; it is pinned as an explicitly labelled KNOWN GAP rather than left implied. Verification, on shared code so the full bar: resolvers+cfg 3170 passed / 1 skipped / 0 failed; `bench/receiver-resolution --check` OK; `bench/scope-capture --check` PASS (15 languages, Swift fingerprint unchanged) — i.e. the bridge change altered no capture output. The 3170 reconciles against the 3167 pre-existing at a5bf4c2da plus exactly 3 new tests; 3167 differs from the older 3166 baseline because 0418b0aac added the matrix's only known-gap row, which emits one extra `it`. Mutation test: with both arms reverted, 3 of the 5 new cases go red, each arm pinned independently — the guard case registers no position key, the position case registers no local-name key. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor: apply cleanup-review findings across the receiver-typing change Four parallel quality lanes (reuse, simplification, efficiency, altitude) over `origin/main...HEAD`. Eleven fixes; both exact-match bench gates hold with every capture fingerprint BYTE-IDENTICAL, so none of this changed what the analyser emits. Reuse — stop re-rolling helpers that already exist: - `walkToScope` moved out of the TypeScript provider into a language-neutral `utils/scope-tree-walk.ts`. Ruby and Dart had begun importing it FROM `languages/typescript/`, which made three unrelated providers depend on the TS module for a generic `Scope`/`ScopeTree` walk. Python's hand-rolled copy — the one this PR's new `self.x = Outer()` path routes through — is folded in, so all six languages now share one traversal. - Swift stops string-parsing a type name. `swiftEnclosingTypeName` split on `<` and `.`; `swiftBaseTypeIdentifier` + `swiftQualifiedBaseTail` do it structurally and correctly skip the sibling `type_arguments` node, which the string form only guessed at. `findEnclosingTypeDeclaration` replaces the inlined ancestor walk. - TypeScript uses the canonical `hasKeyword(method, 'static')`. The previous `child.type === 'static'` is the exact form `isStaticMember` documents as grammar-version-fragile: "`static` can appear as an unnamed token or as a keyword node depending on grammar version; check text." - Both new test suites use `cleanupTempDirSync`, which exists because a pipeline test's open handle surfaces as EBUSY/EPERM on Windows and `force` does not suppress it. This repo shards Windows CI. LATENT DEFECT, found by the reuse lane and fixed: `var a = X(), b = Y();` parses as ONE `declaration` with two declarators, and the query matches it once per declarator with the SAME node — so the first-descendant search handed every declarator the FIRST one's initializer. `b` resolved as `X`. Now reads `nameNode.nextNamedSibling`, which is both correct and free. Pinned by a `multi-declarator-inferred-field` row ordered so the declarator under test is the second; reverting the fix turns exactly that row red with the wrong edge. Efficiency — measured, not asserted: - Dart's shadow set was built eagerly for EVERY method body and discarded 87-100% of the time (a `this.`-prefixed write never reads it). Now lazy and memoised per body, gated on `fields.has()`. Semantics are unchanged: the set is body-wide, so deferring construction cannot change its contents. Worth recording WHY CI could never have caught this: `bench/scope-capture` gates the SCALING RATIO, and the work is linear — ratio stays 1.0 against a 1.5 budget while a constant-factor regression passes straight through. - `isTransparentReceiverWrapper` crossed the `node.type` native getter twice on the common path. One hoisted read, and — since absent and ungated are distinguishable — one `get` replaces `has`+`get`. Simplification: - One `Map<string, string | null>` replaces the parallel Set + Map that both expressed "this wrapper is transparent", with `null` meaning unconditional. - `ids.ts` computed `siblingCallableLabel` twice under two names. The three retry blocks are deliberately NOT collapsed — they use different key builders and materially different gates. - Python's `interpret.ts` nesting was only a consequence of arm ORDER; swapping the arms is unconditionally equivalent (the two differ only when both markers are present, and both orders then yield `constructor-inferred`). - One `isDirectConstruction` predicate replaces the construction-shape test that had been written four times in dart/captures.ts. Deliberately NOT done, each needing a fingerprint rebaseline or new node ids: unifying the six `@type-binding.*-field` markers into one canonical capture (it would change Python's anchor semantics, which must be verified not assumed); a Swift `labelOverride` mirroring Kotlin's four-line fix, which is the real cure for the Method/Function split the bridge currently compensates for; generalising the Swift optional-annotation pattern to `(type_annotation (_))` so the existing strippers handle every wrapper; and merging the TS query with the JS walker, which also carries a JSDoc branch no query can express. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(swift): regenerate the Swift captures golden for the optional-annotation pattern CI caught what my local runs did not: `swift-captures-golden.test.ts` pins `emitSwiftScopeCaptures` output across every `swift-*` fixture, and this branch changes that output. It is a THIRD capture gate, separate from the two exact-match benches already rebaselined here — `bench/scope-capture` hashes a different corpus, so its Swift fingerprint moving did not imply this one, and passing it was not evidence this was clean. The drift is digest-only: 37 changed lines, 37 in each direction, no capture entry added or removed. That is the expected shape for `(type_annotation (optional_type (user_type …)))` making optional properties emit an annotation binding they previously did not, plus the `@declaration.qualified_name` now carried on Swift method declarations. Regenerated with the mechanism the test itself prescribes (`UPDATE_GOLDEN=1`), not by relaxing the assertion. Verified after: all Swift unit + resolver suites green (4 files, 124 tests), and `bench/receiver-resolution --check` still exactly matches its baseline. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix: three more wrong-owner defects, found by a second review round A second tri-review of this PR found THREE new P1 wrong-owner defects — every one of them in code the FIRST round had already fixed. All three are the same root shape: an incomplete ENUMERATION of binder or scope forms. That class has now bitten this branch four times (formal parameters, then these), so two of the three fixes below deliberately attack the class rather than the instance. 1. DART 3 PATTERN BINDERS (P1, reproduced by two independent lanes). `addDartBinderName` enumerated five binder node types, and every Dart 3 pattern form parses into node types in NONE of them — so a pattern-bound local did not count as a shadow and its write retyped the CLASS FIELD: class Host { var session = Cache(); void load() { final (session, count) = (Session(), 2); } void use() { session.ping(); } // resolved Session.ping, not Cache.ping } The grammar hides every rule that would carry a binder (`_pattern_field`, `_list_pattern_element`, `_guarded_pattern`, …), inlining children onto the enclosing visible pattern node, so binders land as direct `identifier` children of just two leaf types. Covers all 10 pattern types that can hold one; the eight container types are defence, since the grammar demonstrably inlines identifiers onto containers already. THE COMPOUNDING PART: a grammar-derived coverage guard reads `nodeTypeInfo` and fails if the grammar declares a `*pattern*` type the fixtures do not exercise. A grammar bump adding an 11th type now turns the suite red instead of silently reopening this bug a third time. 2. RUBY BLOCK-RECEIVER `self` REBINDING (P1 here, both Claude lanes + Codex, which rated it P2 — the engines agreed the defect is real and disagreed on severity). `isRubyInstanceIvarWrite` enumerated `singleton_method`/`singleton_class` as the ways `self` gets rebound. A `def` inside a BLOCK attaches to the block's receiver, so `Struct.new(:x) do def warm; @a = Beta.new; end end`, `Class.new do … end`, `class_eval`, and `other.instance_eval { @a = … }` all published onto the nearest LEXICAL class. Deliberately NOT fixed by listing rebinding call names: that set is OPEN — `def helper(&blk) = Foo.class_eval(&blk)` rebinds a block it merely receives, and nothing in the block's own syntax reveals it. An allow-list of "safe" iterators would be the same defect one level down. The rule is structural: crossing ANY block boundary makes ownership unprovable, so discard. Complete by construction rather than by enumeration. ACCEPTED COST, asserted not hidden: `[1].each { @shared = X.new }` in an instance method really is the instance's `self`, and this drops it — that block is syntactically identical to the `instance_eval` one. It has its own row (`plain-block-self-ivar`) so the loss is visible rather than discovered later. 3. STATIC FIELD INITIALIZERS (P1, found by Codex/gpt-5.6-sol, corroborated). A `static` field initializer was captured as an ordinary instance binding, and since both land on one Class scope at the same `constructor-inferred` strength, the later wins the `>=` tie-break — so a static field retyped the instance field of the same name (`this.p.hit()` -> `Wrong.hit`). Unguarded in BOTH `javascript/query.ts` and `typescript/query.ts`; the existing `isStaticMethodThis` only ever covered the `this.x =` assignment form. Two things surfaced while fixing it: the TS `annotation` pattern collides identically and is PRE-EXISTING, not introduced here; and JS `static constructor(){}` had no guard where TS did — the .ts/.js divergence this PR's own comment claimed could not happen. Dart has no same-name twin (the language forbids it), but a static method's receiver-less write named a library-level variable and DISPLACED the constructor's binding. Fixed narrowly, with a counterweight row (`static-field-declaration-still-types-its-receiver`) that goes red if anyone widens the guard into "drop every static binding" — reading a static by bare name from an instance method is ordinary Dart and must keep working. ACCEPTED COST: `typeBindings` has one map per Class scope with no static/ instance split, so a static field is dropped rather than recorded separately, losing typing on a TS/JS `Host.p.hit()` static receiver chain. Missed edge over wrong edge, per compound-receiver.ts:519-537. Every new row asserts a SURVIVING POSITIVE target, never an empty set: the pre-fix value in each case is a DIFFERENT non-empty target, so none can pass vacuously — the trap this branch already fell into once. Mutation-verified per fix: reverting each turns exactly its own rows red (17 Dart, 6 Ruby blocks, 5 static) with every pre-existing row green. Matrix 49 -> 80 tests. Siblings 510 passed. tsc clean. scope-capture PASS (15 languages, all ratios within gate). Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(dart): mask a shadowed field on the READ side, not just the write side The review critic refused to pass this PR while this was open, and it was right to: this is the same wrong-owner shape as the three defects fixed in the previous commit, except this one is introduced BY this PR rather than merely missed by it. THE DEFECT. Typing an unannotated field from a constructor assignment (`var conn; Host() { conn = Alpha(); }` binds `conn` on the CLASS scope) is this PR's whole point. `emitDartFieldAssignmentBindings` correctly declines to WRITE that binding when a member body rebinds the name — but the shadow set gated writes ONLY. `collectDartBodyShadows` had exactly one call site, inside the bare-name write branch. Nothing consulted it on the read side, so a bare-name READ of a shadowing binder the resolver cannot type walked straight past the local and hit the field binding this feature mints: class Host { var conn; Host() { conn = Alpha(); } void probe(List<Beta> xs) { for (final conn in xs) { conn.inner(); } // conn is a Beta element } } // resolved Alpha.inner, not Beta.inner Reproduced in SEVEN binder shapes, not the one the review reported: for-in (`final` and `var`), untyped formal parameter, plain local `var`, catch binding, closure parameter, and record pattern. Delete the constructor and the same read emits NOTHING — which is what proves this PR introduced it. "No edge" became "wrong edge", the one failure mode compound-receiver.ts:519-537 exists to prevent. THE FIX uses `Scope.ownsReceivers` (#2701), the primitive that already exists for exactly this, rather than inventing a mechanism. `scope/walkers.ts` consults `typeBindings` FIRST at every scope and only then honours the mask, so a shadow the resolver CAN type still wins — an annotated `void probe(Beta conn)` keeps `Beta`, because `synthesizeDartSignatureBindings` anchors parameter bindings on the same body node and they land on the same Function scope. The mask fires only where the alternative was a fabricated type. Plumbing follows TypeScript's `@receiver-owner.this` precedent: the marker rides the same synthesized match as `@scope.function` and sits outside the `@scope.` namespace so `anchorCaptureFor` cannot mistake it for the anchor. Dart differs only in that its function scopes are synthesized in captures.ts rather than declared in the .scm, so the names travel as capture TEXT — a `CaptureMatch` carries no AST node, so the reader cannot re-derive them. SCOPE, and the costs taken knowingly rather than hidden. The mask is `shadows ∩ fields` and nothing wider. Masking every locally bound name would also fix a library-level `var logger = Logger();` shadowed by a loop variable, but it changes resolution for code this PR never touched. Three consequences are documented on `dartShadowedFieldsCapture`, not buried: the wider case is left open; an ANNOTATED field shadowed by a binder is masked too (correct Dart, but it touches resolution predating #2807); and `mixin` bodies are reached, since the grammar gives them a `class_body`. PERFORMANCE, measured rather than asserted. The mask is emitted eagerly in Pass A, where `collectDartBodyShadows` used to be lazy — the replaced comment recorded 87-100% of eagerly built sets being discarded, ~15% of Dart emission. Actual cost on the scope-capture large corpus, median of 3: 405.6ms with the mask vs 390.0ms without, ≈ +4%. Fingerprint and capture_groups are byte-identical across both arms, so no corpus fixture emits a mask at all — that 4% is the cost of the CHECK alone. Not visible to `bench/scope-capture`, which gates the scaling RATIO and is blind to a linear constant factor; stated here because the gate cannot state it. (3 samples per arm, blocked not interleaved — an estimate, not a rigorous number.) A per-file memo keyed by node span makes both passes share one walk per body, so the write side no longer pays a second one. SCHEMA_BUMP 40 -> 41 with its exact-value pin, since capture emission changed. Re-check against origin/main immediately before merge — main was 39 at commit time. Mutation-verified both directions, which is the part that matters: - unwire `scopeOwnsReceivers`, rebuild -> exactly 2 rows red (`loop-var-read-does-not-see-the-field`, `pattern-read-does-not-see-the-field`), 83/85 green. - over-widen the mask (drop the `shadows.has` test) -> 28 Dart rows red, including `unshadowed-read-in-a-shadowing-class-still-resolves`. The three control rows stay green under the first mutation BY DESIGN — they guard overreach, not the defect; the second mutation is what proves they are live. Pre/post on the trigger row: `{Class:Alien, Alien.inner#0, Outer.inner#0}` -> `{Class:Alien, Alien.inner#0}`, so no row can pass vacuously. Matrix 80 -> 85 tests. Sweep 3220 passed (was 3215; exactly +5). tsc clean. All four capture gates green: receiver-resolution OK, scope-capture PASS (15 languages, no fingerprint moved, nothing rebaselined), callable-value-flow PASS, swift golden 9. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(ts,js): let each language name its own class-field node type CI caught a defect the whole review round missed. `grammar-literal-validation`: 1 dead grammar literal(s) found: - node-type "field_definition" — languages/typescript/captures.ts:0 — not valid in [typescript] `isStaticClassFieldBinding` held BOTH spellings in one set — `public_field_definition` (TypeScript) and `field_definition` (JavaScript) — so that one predicate could serve both languages. But the predicate lives in `typescript/captures.ts`, and the gate checks every literal against the grammar of the FILE it appears in. `field_definition` is not a TypeScript node type. The literal was NOT dead code: `javascript/captures.ts:42` imports the predicate and calls it against real JS nodes, so the guard worked. The gate is still right to fail it, and for exactly the reason this predicate's own docblock gives for preferring `hasKeyword` over a node-type test — "a node-type test silently stops firing on a grammar bump and every static field starts retyping its instance twin again". A literal already dead in its own file is that failure shipped pre-broken: nothing in the TypeScript file would ever have told us. Each language now names its own node type and passes it in (`TS_CLASS_FIELD_DEFINITION_TYPES` / `JS_CLASS_FIELD_DEFINITION_TYPES`), so every literal is checked against the grammar it belongs to. The `hasKeyword` logic and the static/instance reasoning stay shared and unchanged — only the node-type set moves to the caller. WHY THE LOCAL SWEEP DID NOT CATCH IT: I ran `test/integration/resolvers` and `test/integration/cfg`. The gate is `test/integration/grammar-literal-validation. test.ts`, in the parent directory. Scoping a sweep to the subdirectories a change touches is precisely how a cross-cutting gate gets skipped. grammar-literal-validation 4 passed. tsc clean. Full `test/integration` + `test/unit/scope-resolution`: 6305 passed, 14 failed — all 14 in e2e/environment suites (fts-extension-e2e 9, analyze-heap-oom-e2e, cli-e2e, analyze-wal-checkpoint-failure, plus interproc-taint and parse-impl-env-reads, which BOTH pass in isolation and fail only under 28-worker load). CI runs the same files green. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(dart,ts): pin all seven read-side binder shapes; correct a wrong accepted-cost claim Two review findings, one of which turned out to be a documentation defect rather than the design defect it was filed as. S8 — THE READ-SIDE FIX PINNED 2 OF THE 7 SHAPES IT REPORTED REPRODUCING. `ab2f48c17` reported the wrong-edge defect reproducing in seven binder shapes and landed rows for two. The stated mitigation was that all seven route through one `collectDartBodyShadows` enumeration whose completeness the grammar-derived coverage guard protects. That mitigation is NARROWER THAN CLAIMED: the guard filters `nodeTypeInfo` on `type.includes('pattern')`, so it covers the pattern family and NOT catch bindings, closure parameters, plain locals, or formal parameters. Narrowing `addDartBinderName`'s catch arm would have turned no row red. All seven were re-measured by unwiring `dartScopeOwnsReceivers` and rebuilding. Every one gained the wrong edge `Outer.inner#0` — none had to be dropped as non-reproducing. Five new rows: formal parameter, plain local `var`, catch binding, closure parameter, for-in `var`. Non-vacuity established structurally, not by assertion: the Dart AST was dumped first to confirm each fixture produces the node `addDartBinderName` actually inspects (`formal_parameter`, `initialized_variable_definition`, `catch_parameters`, `for_loop_parts`). The catch row uses a bare `catch (zf)` rather than `on Err catch` deliberately — an `on` clause names a type, which would make the row measure type resolution instead of the mask. S7 — THE ACCEPTED-COST COMMENT WAS WRONG, AND THAT IS THE FINDING. It claimed dropping a static field's binding trades a wrong edge for a missed one. Measured on a same-name twin, that is false: read with the drop without it this.p (instance twin) Outer correct Alien wrong Host.p (static twin) Outer WRONG Alien correct Host.q (static, no twin) none — missed Alien correct The wrong edge did not disappear. It MOVED to the static read, which now picks up the instance twin's type. Only the no-twin case is a genuine missed edge. The trade is still right — `this.p` is far more common than `Host.p` — but it was documented as safer than it is, and a reader deciding whether to revisit it was being given the wrong picture. NAMESPACING WAS EVALUATED AND DELIBERATELY NOT DONE. `Host.p.hit()` resolves through `foldReceiverChain` in shared `compound-receiver.ts`, which explicitly discards whether a chain's base was a class reference or a value (:519-527). The class-constant bit exists only on the text-cascade path (`currentIsClassConstant`) and is consumed solely by `isConstructionSelectorHop`; TS/JS take the fold, not the cascade. `Scope.typeBindings` is `ReadonlyMap<string, TypeRef>` with no static field. `ownsReceivers` cannot help — it is a suppressor that can only REMOVE a binding, never route to a second one. A real fix needs `FoldState` to carry the bit plus a key convention in shared code (an AGENTS.md:42 hook if not language-neutral), it crosses the worker boundary so it needs a SCHEMA_BUMP, and `compound-receiver.ts:826` iterates every binding for `fieldFallback` so a namespaced key would leak straight back in as an ordinary field. Not a cheap or safe change — and it would have been made with ZERO existing tests pinning static-read behaviour. So: smallest safe step instead. Two rows pin the measured behaviour (`static-read-of-a-same-name-twin-picks-up-the-instance-type` asserts the positive wrong target, not an empty set; `static-read-without-a-twin-loses-its-type` is a known-gap), and the comment now says what actually happens. Anyone who revisits this starts from measurements rather than from a claim. No SCHEMA_BUMP: the `captures.ts` change is comment-only — verified, the diff has no non-comment added lines. Mutation red-rows 2/85 -> 7/90; each new row fails with a strictly larger set (`+Outer.inner#0`), so none can pass vacuously. Overreach control still live: dropping `shadows.has` turns 28 rows red including `unshadowed-read-in-a-shadowing-class-still-resolves`. Matrix 85 -> 92 tests. Sweep 3231 passed, 0 failed. tsc clean. All four gates green, no fingerprint moved, nothing rebaselined. Refs #2807 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(python): stop a dotted callee from fabricating a constructor type S4 and S5 from the review round. They are ONE defect, not two, and the real one is wider than the review described. Both live in a 32-line block THIS PR adds (`@@ -116,0 +117,32 @@` — a pure addition), so neither is pre-existing. THE DEFECT. `constructorCallTypeName` rejected only a callee rooted at the receiver and returned every other dotted callee whole to `resolveTypeRef`, which resolves dotted names through `QualifiedNameIndex` — and that index matches the TRAILING SEGMENT against a class of that name even when the callee is a method on an unrelated object: class Alpha: def ping(self): return 1 class Factory: def Alpha(self): return "not an Alpha" # a METHOD class Host: def __init__(self, f): self.svc = f.Alpha() # svc is a str def run(self): return self.svc.ping() # measured: Host.run -> Alpha.ping, fabricated WIDER THAN FILED: the review framed the trigger as a callee rooted at an `__init__` PARAMETER. Measured, the root's binding form is irrelevant — a module-level variable (`shared_factory.Alpha()`) fabricates identically. Any rule written against what the root binds to would have fixed half the defect and left the other half looking fixed. Both fabrications now have rows. S5 IS A SYMPTOM, NOT A SECOND DEFECT. `self.conn = Outer()` then `self.conn = Registry.get()` typed the field as `"Registry.get"` (resolving to nothing, so the edge vanished) only because the dotted arm accepted `Registry.get` as a constructor in the first place. Once dotted callees yield no candidate, there is nothing weak left to displace with and `Outer` survives. So `>=` is untouched and NO second mechanism was added: between two REAL constructions last-write-wins is correct, and the existing `ReassignedField` matrix row depends on it. Tightening the tie-break would have been the wrong fix to a symptom. THE FIX: accept a bare `identifier` callee only. Refusing ambiguous evidence at CAPTURE time rather than resolving-then-rejecting is deliberate — the target-kind route is not reachable from this file (`resolveTypeRef` already filters `TYPE_KINDS`; the fabrication comes from a trailing-segment match in `scope/walkers.ts`), and the root-alias route would collide with PR #2828, which is rewriting exactly how an unaliased dotted namespace import resolves. This change is orthogonal to #2828 by construction: it changes what is CAPTURED, never how a name is looked up, and touches none of its files. WHAT THE DOTTED ARM WAS ACTUALLY BUYING: nothing. The review (and this PR's own docblock) justified it with `self.u = models.User()`. Measured, that shape emits NO edge before or after this change — an instance field's binding lands in CLASS scope, which never reaches the namespace split. The shape that really resolves is the module-level local `u = models.User()`, which comes from `query.ts` and is untouched here. The arm's entire measured contribution was fabrications, which is what made the fix cheap. #2828 COMPATIBILITY, checked not assumed: `import pkg.user` -> `self.u = pkg.user.User()` resolves to nothing both before and after, so this cannot stop it resolving. No test row pins that shape ON PURPOSE — asserting its current empty state would plant a tripwire that goes red the moment #2828 lands. If #2828 also teaches the FIELD path the namespace split, re-enabling dotted field callees becomes a live option; the docblock says so, and says why redoing it capture-side would re-open the fabrication. SCHEMA_BUMP 41 -> 42 with its pin. This is parse-time capture emission: after the fix `self.svc = f.Alpha()` emits no `@type-binding.constructor` capture at all, so a v41 warm cache replays the pre-fix capture set for byte-unchanged files and keeps serving the fabricated edge (GUARDRAILS.md:34). A within-PR re-bump, not a collision fix — 40/41/42 are all this unmerged branch's, and `origin/main` is at 39. Re-check against origin/main immediately before merging. Mutation-verified in BOTH directions, which is what shows the fix is placed at the right width rather than merely working: - revert the fix -> exactly 3 red: both S4 fabrication rows + the S5 displacement row (8 green) - reject EVERY callee -> exactly 3 red: the three positive-typing rows (8 green); the S4 rows correctly stay green The two mutations hit DISJOINT row sets — too loose and too tight each break a different half. No row asserts an empty set: the three "must not type" rows call `Alien.ping()` as a witness so a regression SWAPS a target in rather than emptying. Non-vacuity is asserted in the test itself — one guard checks every caller node is live, another asserts the `Alpha` class / `Factory.Alpha` method name collision the fabrication NEEDS is actually present, so the rows cannot rot into passing for the wrong reason. Sweep 3268 passed, 0 failed. Python unit + python.test.ts 342 passed. tsc clean. All four gates green — no bench cell moved, nothing rebaselined.

Gergő Magyar	010a7d806a	fix(schema): declare the full scope-resolution relation cross product (#2792) (#2793) ... * fix(schema): declare the full scope-resolution relation cross product (#2792) `RELATION_SCHEMA` was hand-listed, and every prior fix added only the FROM/TO pair named in a crash report — `Const→Method` in #2769, the Swift/Rust member pairs before it. So `analyze` kept aborting at `assertDeclaredPair` on the next codebase whose edges happened to land on a different pair; #2792 reports `Class→Variable` on Java. Audit the surface instead of the symptom. `buildGraphNodeLookup` skips any node whose label is not in `isLinkableLabel`, so the lookup holds only linkable-labelled nodes — and both endpoints of every graph-bridge edge resolve through that lookup. The emittable surface is therefore exactly: FROM LINKABLE_LABELS + File (the module-level caller fallback) TO LINKABLE_LABELS + CALL_TARGET_TYPES `isCallerAnchorLabel` is a strict subset of linkable and contributes nothing on top. `CALL_TARGET_TYPES` contributes `Delegate`, which `tryEmitEdgeWithExplicitTargetId` can emit without going through the lookup at all. Generate that 14x14 block into the DDL rather than listing it: 223 -> 322 declared pairs, and no future pair from these sets can be missing by construction. The containment/inheritance/DI/route/cluster/PDG pairs stay hand-declared — no single predicate describes them. Both label sets live in the ingestion layer, which `core/lbug` must not import, so schema.ts carries twin lists. test/unit/schema-pair-coverage.ts derives the requirement from the originals and fails CI when either set grows without the pairs landing here — the piecemeal loop this fix ends. Measured before widening: at 322 pairs the cost is inside noise (1.09s vs 1.12s per 300 anchored queries on a 32-table DB), but the full 32x32 cross product is ~1.8x on untyped-endpoint anchored queries. The audited subset is the right scope, not "declare everything". INCREMENTAL_SCHEMA_VERSION 34 -> 35: LadybugDB fixes endpoint pairs when the rel table is created, so a pre-v35 database physically cannot store these edges. Closes #2792 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(schema): declare the non-bridge structural pairs COBOL and Vue emit The generated scope-resolution block closed the half of RELATION_SCHEMA a label predicate can describe. The hand-declared half was still stale: with #2791's Function->Variable fix applied, `analyze` continued to abort on this repo's own test/fixtures/lang-resolution with Relationship label pair Module→Property is not declared A full sweep (assertDeclaredPair patched to log-and-skip, run over the whole fixture corpus) found 13 undeclared pairs over 106 edges. This branch already covered 3 of them via the cross product; the remaining 10 come from emitters outside the graph bridge: - cobol-processor.ts mints Module / Namespace / Record / Property / CodeElement and wires them with CONTAINS, CALLS and ACCESSES (9 pairs) - vue-sfc-extractor.ts emits BINDS_EVENT_HANDLER from a handler Function to the child component's File, the only edge whose target is a File (1 pair) CodeElement, Namespace, Record and File are in neither scope-bridge label set, so neither the generated block nor schema-pair-coverage.test.ts can reach them. Adds test/integration/structural-pair-coverage.test.ts, which derives the requirement from a corpus instead of a predicate: it runs the real pipeline over the non-bridge fixtures and requires every FROM/TO pair they produce to be declared. Mutation-checked — dropping `FROM Function TO File` fails it with exactly Function|File. Verified: cobol-app, vue-basic and php-transitive-traits now index instead of aborting; the full lang-resolution corpus completes at 10,876 nodes / 18,517 edges; scrypster/muninndb at 0b7a4272 (the #2789 repro) completes at 20,069 nodes / 71,580 edges, matching #2791 exactly, so this supersedes that PR. * refactor(test): simplify the structural pair coverage guard Cleanup pass over the previous commit. No behaviour change to the schema. - reuse `FIXTURES` and `runPipelineFromRepo` from resolvers/helpers.ts instead of re-deriving the fixture root and importing pipeline.js directly - gate on `distWorkerExists()` like every other integration test that passes `workerUrlForTest`, so a missing dist skips rather than fails - run the three fixtures with `it.concurrent.each`; they share nothing and the cost is almost all worker spawn plus grammar load, which overlaps well (tests phase 21-24s -> 5.6s measured) - replace the sentinel-in-a-Set filter with a plain `.filter()` chain, matching the sibling unit test, and move the declared/table lookups off the per-edge path onto the deduped set - move the pure string pin out of the integration tier into schema-pair-coverage.test.ts, where the identical construct already lives, so it needs no build and survives fixture deletion - trim the schema and test prose that restated the code, and correct the BINDS_EVENT_HANDLER attribution: it is emitted by languages/vue/scope-resolver.ts, not vue-sfc-extractor.ts - amend the v35 comment to mention the 10 structural pairs it now also stamps Still mutation-checked: dropping `FROM Function TO File` now fails both the integration sweep and the unit pin with exactly Function|File. 89 tests green. * fix(schema): generate the attachment pair surface and close four analyze aborts Review of the generated scope-bridge cross product found four `analyze` hard-aborts still live at head, each reproduced end-to-end on the default user path (`analyze --index-only --skip-git`): Method→Annotation Spring `@Bean` + `@ConditionalOnMissingBean` (Java + Kotlin) Method→File Vue Options-API `methods:` handler bound to a child event Namespace→Record COBOL `DECLARATIVES` / `USE AFTER STANDARD ERROR ON <file>` Class→Tool `@mcp.tool()` applied to a class All four are pre-existing on main, and both existing guards were structurally blind to them: the unit guard derives from LINKABLE_LABELS ∪ CALL_TARGET_TYPES (none of Annotation/Tool/Record/File-as-target is a member) and the corpus guard ran three fixtures that exercise none of these emitters. All 16 tests passed while all four crashes were live. The PR's model — "bridge endpoint × structural endpoint" — does not fit: Namespace→Record is structural on both sides. The property that does hold is that the ANCHOR is a lookup result, not a literal at the emit site, so the emitter cannot constrain its label. That gives a second closed-form rule: DEFINITION_ANCHOR_LABELS × ATTACHMENT_TARGET_LABELS DEFINITION_ANCHOR_LABELS is derived from NODE_TABLES by subtraction, so a new node table joins automatically. 332 → 450 declared pairs. Sized against a committed harness (gitnexus/bench/schema-pairs), real @ladybugdb/core, identical data: 450 costs 0.93–1.05× of 332 on untyped-endpoint anchored queries — inside noise — versus 1.22–1.43× at 641 and 2.03–2.34× at 1024. The harness reproduces the known #2792 cliff, which is what makes the 450 figure trustworthy. Also in this change: - Delete the 161 hand-declared pairs the rules already generate (233 → 72). The declared set is byte-identical at 450; those lines were load-bearing shadow, because the generator suppresses anything already declared structurally, so narrowing a rule later would silently keep pairs alive. A new guard fails CI if a hand-declared pair is ever re-added inside a rule. - Import LINKABLE_LABELS / CALL_TARGET_TYPES instead of hand-copying them. The twins' stated justification ("the ingestion layer must not be imported here") is false: csv-generator.ts and lbug-adapter.ts, siblings in the same directory, already do, and no rule in AGENTS.md / ARCHITECTURE.md / CONTRIBUTING.md / GUARDRAILS.md states otherwise. - Resolve `resolveStreamGraphEmit` after the guards that rebind `options.force`, not at function entry. It gates on `force`, and every freshness guard runs ~360 lines later, so the v34→v35 bump would have pushed every existing index down the non-streamed emit path — losing the #2680 memory streaming added for the #2649 kernel-scale OOM, for exactly the population most likely to be memory-constrained. - `UndeclaredRelationPairError` now carries the relationship type, both node ids and the source file, with a matching CLI branch. The old message named only the abstract label pair, which a user could not act on. Found through the cause chain, since pipeline-phases/runner.ts rewraps every phase failure. - Share one classifier (`relPairKeyFor`) across the router, both emit sinks and the corpus guard, which previously hand-mirrored the router's skip rule; one cause-chain walker in lib/utils.ts; one exported pair-matching regex. - Corpus guard: four new fixtures reproducing the aborts, per-fixture sentinel pairs so a fixture that stops emitting fails loudly instead of passing vacuously on an empty graph. The per-edge path stays allocation-free: the failure context is passed positionally and the message is built only inside the throw.

Verified corpus-only, not a capture change: with that one fixture moved aside the fingerprint is byte-identical to the prior baseline (d45bb091…), and 81daf370e touches no COBOL capture code.

Gergő Magyar	9c24e3459e	fix(rust): qualify items by their enclosing mod chain so same-named ones stay distinct (#2742) (#2745) ... * fix(rust): let the qualified-call filter see inline modules The negative filter added in #2741 builds its set of known module names from FILE PATHS, so an inline `mod x { … }` — which appears in no path — was absent from it. Every module-qualified call into an inline module was therefore rejected before any candidate channel ran, which is a hole in that optimisation rather than in the resolution logic it guards. The per-pass index now unions the file-derived names with inline module names taken from the scope model: a `mod` declaration binds a `Namespace` def locally in the declaring scope, and that binding is the only place an inline module's name exists. Collected in the same walk that already builds the module → scope map, so it costs no extra pass. Found while fixing #2742, where a correctly resolved call into `mod inner { … }` still could not reach its target.

For the defs that carry a prefix the qualified name is a bare TAIL, so the plain key happily matched a same-named item at a different namespace depth in the same file and returned it before the more specific retry was ever reached. The namespace-prefixed key is strictly the more specific of the two, so it is now tried first. Where no such node exists the lookup falls through to exactly the previous order, which keeps the #1982 behaviour this retry was added for. Without this, a call into `mod inner { fn dispatch }` resolved to the correct definition and then mapped it onto the crate-root `fn dispatch` node — the self-loop #2742 describes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01J5nWP4BFeBSjbQ3uqAjtxV * fix(rust): qualify items by their enclosing mod chain so same-named ones stay distinct (#2742) Node identity is `<label>:<file>:<qualifiedName>` and carried no module path, so an inline `mod inner { fn dispatch }` and a crate-root `fn dispatch` in the same file collapsed onto `Function:<file>:dispatch`, first-wins. Resolution already picked the right definition — the target simply was not representable, so a correct resolution still rendered as a self-loop and `impact` reported the real callee as unreached. The mechanism already existed: `qualifyRustImplTargetByModScope` has walked `mod_item` ancestors for impl targets since #1982. Generalised to `qualifyByEnclosingModScope` and applied to free items, so `mod inner { fn dispatch }` becomes `Function:<file>:inner.dispatch`. Keyed purely on the `mod_item` node type, exactly as the impl qualifier already was, so it is a no-op for every language whose grammar has no such node. Two constraints found by tests rather than by reading, both now encoded: - The helper normalised `::` to `.` unconditionally. With no enclosing `mod` that rewrote a top-level `impl a::Inner` from `a::Inner` to `a.Inner` and moved its node id away from the one the HAS_METHOD owner edge emits, breaking the #1975 scoped-impl ownership. It now returns raw text untouched when there are no mod segments, which also makes the change strictly additive for every id that has no enclosing module. - Qualification is scoped to items with no enclosing class/impl. A method already carries its owner's name, and that owner's id is mod-scoped by the impl qualifier, so qualifying the method again breaks the same byte-for-byte agreement. Same-named methods on same-named types in sibling modules therefore still collapse — a narrower residual than the free-item case fixed here, and one belonging to the owner edge rather than to this path.

Node ids change for every Rust item inside any `mod` block, and `#[cfg(test)] mod tests` makes that close to every Rust repository. A pre-v25 index therefore holds ids an incremental top-up cannot reconcile — the old nodes would simply be stranded — so the reuse gate has to force a full re-analyze. The qualified name is computed in the parse worker, so a warm parse cache would likewise replay the old unqualified ids and keep the collapse. This branch originally claimed v24; #2708 took that number and merged first, so it is renumbered to v25 here. That is exactly the collision the v29 note in parse-cache.ts warns about, and re-checking against origin/main at rebase time rather than at branch time is what caught it. #2708 did not touch `SCHEMA_BUMP`, so 32 is free. The version-pin test moves with the bump by design, including the new pre-v25 row in the reuse-gate table.

The mint moved; the owner-edge anchor did not. `findEnclosingClassInfo` mints a member's owner id from the container's BARE `nameNode.text` and only follows a qualified shape when the provider sets `classExtractor.qualifiedNodeId`, which Rust does not. So every `struct` / `trait` / `enum` / `impl` declared directly inside a `mod` got a node id that none of its member edges pointed at. Five lines of idiomatic Rust were enough: pub mod engine { pub struct Config { pub retries: usize } } NODE Struct:src/lib.rs:engine.Config DANGLING HAS_PROPERTY Struct:src/lib.rs:Config -> Property:src/lib.rs:Config.retries The rows are discarded by the IGNORE_ERRORS COPY retry, so the struct silently lost every field. A trait impl inside a `mod` additionally dropped its METHOD_IMPLEMENTS edge outright. The same gap put `impl a::Inner` inside a `mod` back on the #1975 rake that `qualifyByEnclosingModScope`'s own docblock warns about. The impl-target branch deliberately fires only for an UNSCOPED `type_identifier`; the new gate had no such restriction and picked up the scoped targets that branch had just excluded, minting `Impl:<file>:outer.a.Inner` against an anchor still reading `Impl:<file>🅰️:Inner`. The member side was already excluded via `!enclosingClassInfo`. This adds the owner side, gated on `MEMBER_OWNER_NODE_TYPES` — derived from `CLASS_CONTAINER_TYPES`, which is already the single source of "this node type owns member edges" and already carries an INVARIANT note binding it to `CONTAINER_TYPE_TO_LABEL`. A language adding a container therefore cannot gain a mismatched id shape here without also failing that invariant. Keyed purely on tree-sitter node types, so no language name enters shared ingestion. `union_item` is listed too: its fields are captured as Property but it is not a recognized owner, so they carry no HAS_PROPERTY edge and cannot dangle — it is here so a union's id keeps the same shape as the struct beside it. Containers still collapse across sibling modules, exactly as before this fix. That residual belongs to the owner edge, and is not worked around here. Regression tests use the UNFILTERED `findDanglingEdges(result)`. Every other dangling assertion in `rust.test.ts` passes `['HAS_METHOD']`, which is precisely why the HAS_PROPERTY breakage shipped with a green suite. They assert the NODE id rather than only the edge's anchor, because the anchor was already bare while the bug was live — an edge-only assertion passes in both builds. All four fail when the new gate clause alone is reverted.

A `mod` nested inside an inline `mod` binds in the parent module's scope, so the walk saw depth-1 inline modules and missed every nested one — `tools` never entered the set and the negative filter rejected the qualifier before any candidate ran. `declaresSubmodule` had the same root-only assumption, so even with the name known the candidate `outer::tools` was never yielded. Both now read the def index. Names come from every `Namespace` def; inline module PATHS are derived from the members' `namespacePrefix` rather than from the `mod` defs, because a `mod` def carries no nesting information of its own — inside `mod outer { mod tools { … } }` the inner def is `qualifiedName: 'tools'` with NO `namespacePrefix`, while every def within it is stamped `outer.tools`. A `Namespace` scope also owns its OWN def rather than its children's, so the scope tree cannot answer this either: the `mod outer` scope lists `outer`, never `tools`. Restricted to non-empty prefixes, so this stays a DECLARATION check. Including file-derived modules would let an undeclared or `cfg`-gated file on disk outrank a real `use` binding — the regression #2741's review already fixed once. File-backed submodules therefore keep going through the binding check. A module with no defs at all is absent from the set, which is harmless: it has no member for a qualified call to resolve to. Cost is one pass over an already-resident def index, memoized per resolution pass on the existing WeakMap — the same order of work as the binding walk it replaces, and it subsumes it. `isLocalNamespaceBinding` was going to single-source the duplicated "locally declared submodule" predicate the review flagged; deriving paths from members removed the second copy outright instead. Regression fixture covers depth 2 and depth 3, so the fix is depth-agnostic rather than depth-2 special-cased.

The crate-root-relative candidate then captured it: // src/lib.rs pub mod Buffer { pub fn with_capacity() -> usize { 111 } } // src/b.rs use crate::c::Buffer; // the real target lives in c.rs pub fn call() -> usize { Buffer::with_capacity() } base: (no CALLS edge — unresolved) PR: CALLS b::call -> Function:src/lib.rs:Buffer.with_capacity <- fabricated `ids.ts` states the doctrine this broke: a missing edge is the correct failure direction for a graph whose consumers include `impact`; a fabricated caller is not. The base produced the missing edge and the PR produced the fabricated one. That third candidate is the loosest of the three — a guess at a crate-root-relative path the caller never wrote, kept for 2015-edition style. In Rust 2018 a bare first segment resolves in the CALLER's module, so a local binding for that segment settles the question: it is now skipped when the head names anything non-module in the caller's own module. Candidates 1 and 2 are untouched, and they run first, so the legitimate `use crate::tools;` path is unaffected. The binding lookup goes through `lookupBindingsAt`. A first attempt read `Scope.bindings` directly and the guard never fired: a `use` binding is finalize OUTPUT and absent from the scope's own local table, which is exactly the imported-type case being guarded. Contract I8 in `contract/scope-resolver.ts` requires that channel anyway. The regression test asserts the forbidden TARGET rather than an empty edge set, and separately asserts the module member still exists as a node — otherwise the test would pass just as well if the call went unresolved for some unrelated reason, or if the module node disappeared entirely.

For a namespace- or `mod`-qualified def those keys are simply dead: `node-lookup.ts` registers them under the QUALIFIED name (`inner.dispatch#0`) while this side built `dispatch#0`. The keys exist to separate overloads, so a mod-scoped overload set was relying on whichever later key happened to catch it. Verified as a miss rather than a mis-hit before changing anything — an end-to-end run with a crate-root decoy of the same name and arity binds correctly — so this is hygiene, not a live bug. Worth doing while the code is open rather than leaving five keys dead and the behaviour dependent on fallback order. Both name forms now go through one `lookupTagged` helper, most specific first, so a sixth tagged key cannot be added with the bare form only. That also removes the five hand-repeated `qualifiedKey(...)` / `nodeLookup.get(...)` pairs. Also pins the C++ `EXTENDS` retarget this PR's reorder produces. `cpp-two-phase-dependent-base-cross-ns-deep` declares a global `Inner` decoy alongside `ns:🅰️🅱️:Inner`; the base's `qualifiedName` is a bare `Inner` with the path on `namespacePrefix`, so only the prefixed key separates them, and only if it runs first. The improvement was riding unasserted in a Rust-scoped PR. The captures golden covers every `rust-*` fixture, so the three fixtures added by this review series drift it; regenerated with UPDATE_GOLDEN=1. Verified: 785 tests across cpp / csharp / rust resolvers and the callable-id-lockstep unit test.

Nothing dangled: the `@line:col` suffix already makes a function-local callable's id unique, which is also why the mod segment adds no identity in this position. The path simply read as a lie about the source. It is now skipped rather than reordered — interleaving two qualifier passes to fix the order would be real machinery for a shape whose ids are already unique. Also folds in the three documentation and structure findings from the same review: - The 4-clause gate is extracted to a named `qualifiesByEnclosingModScope`, matching the two conditions directly above it in the same function, which were already named consts. - `qualifyByEnclosingModScope`'s docblock documented only the impl-target contract even though the generalized name has had a second, looser caller since #2742. It now states both, and says which gate belongs to which — that gap is what let the #1975 scoped-impl regression through in the first place. - The "cheap rejection BEFORE any index work" comment was no longer true: `passIndexFor` walks the def index on its first call in a pass. Corrected rather than left to mislead the next reader into thinking the filter is free. What it still buys — skipping the per-site candidate search, the part that scales with the workspace — is stated instead. Verified: 279 tests across the Rust resolver suite and the Rust scope-resolution unit tests. Captures golden regenerated for the extended fixture.

Neither side conflicted textually — the pin and the constant live in different files — so the merge was clean and the test failed instead. That is the pin working as designed: it exists so a bump cannot ride along unnoticed, and this is the fifth time a SCHEMA_BUMP collision has been caught by a guard rather than by review. Updated to 32 with the reason recorded inline. `INCREMENTAL_SCHEMA_VERSION` needs no second bump: 25 was introduced by this unmerged branch, so no released index carries it, and its own pin in `call-summary-schema-version.test.ts` is already consistent. Verified: 119 tests across the parse-cache, schema-version, incremental-orchestration and the two identity suites that arrived with the merge.

I rebaselined the `rust-captures-golden` snapshot and stopped there — a new fixture is a call site of BOTH, and updating only one is how this reached CI red. This is the same class as PR #2743's headline finding, from the other direction: an id-shape change makes every synthetic corpus a call site, and the author fixed the unit-test fixture and missed the bench. Here it is a fixture-count change rather than an id-shape change, and the review that flagged the #2743 lead as "REFUTED, bench/ has no Rust node-id corpus" was right about node ids and wrong about the corpus fingerprint. Noted for the next author in the baseline entry itself. Verified as pure corpus growth rather than a capture-logic shift: removing ONLY the three new fixture directories and re-running reproduces the prior fingerprint exactly (196 fixtures, capture_groups_fp 3432), and restoring them gives the new one (202, 3556). `emitRustScopeCaptures` is untouched by this series. Scaling 1.022 local / 1.057 CI, well inside the 1.5 budget. `bench/python-scope` globs `python-*` only and is unaffected; no other bench walks the Rust corpus. `--check` now PASSes for all 15 languages.

Gergő Magyar	bc76ba2f25	fix(resolution): type inline constructor receivers in every spelling (#2708) (#2737) ... * fix(resolution): resolve constructor-expression receivers (#2708) `Service(db).do_work()` emitted no CALLS edge, so the caller was missing from `impact(direction: "upstream")` and `context()` while the two-step spelling of the same call (`s = Service(db)` then `s.do_work()`) resolved. The receiver reaches `resolveCompoundReceiverClass` intact — Case 0 in `receiver-bound-calls` routes it there because the text contains `(`. The free-call branch then only knew one shape: a function whose return-type binding names a class. A class has no return-type binding, so `Service` resolved to nothing and the member call was dropped. Handle the constructor shape: in languages that construct without a `new` keyword (Python, Kotlin, Swift, Scala) a free call naming a class IS a constructor call, so the expression's type is that class. The existing return-type path still runs first and wins, keeping this strictly additive — `new`-keyword languages never reach the new line because their receiver text keeps the keyword (`new Service(db)`), which matches no class binding. Verified on the issue's 4-file repro: `route_inline` now emits `CALLS → Service.do_work` and `impactedCount` goes 1 → 2. Note the issue's second ask — degrading `epistemic` to `lower-bound` when a receiver goes unresolved — is NOT addressed here. `computeEpistemicBoundary` keys only on the target's own heritage edges and runs at query time against the index, while unresolved references live in an in-memory `resolutionOutcomes[]` that is never persisted. That needs unresolved-receiver counts in the index first, so it is left for a follow-up. Tests: new `python-inline-constructor-receiver` fixture plus three integration cases (inline resolves, two-step still resolves, no cross-class fan-out). Two of the three fail without the source change. Full `test/integration/resolvers` suite passes (2928 tests) — the fix is shared across every language, so no-regression coverage matters more than the new cases. Python captures golden regenerated: additions only, no existing digest changed, confirming capture output is untouched. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RqnsJK3Cnbu3bjdZbzgMMP * refactor(resolution): state the construction rule once, cover every spelling (#2708) The first commit fixed `Service(db).do_work()` by special-casing a bare class-name callee inside the free-call branch of the compound receiver resolver. That was the right rule in the wrong place: it covered one surface syntax out of three, and asserted rather than declared which languages it applied to. Probing the same shape across languages showed the bug is wider: | spelling | languages | dropped before? | |------------------------|--------------------|-----------------| | `Service(db).m()` | Python | yes | | `new Service(db).m()` | JS/TS, Java, C# | yes | | `Service.new.m()` | Ruby | yes | | both forms | PHP, Swift, Dart, | no — already | | | Kotlin | resolved | So the rule is stated once — "constructing a class yields an instance of that class" — and the per-language surface syntax is declared through a new `ScopeResolver.constructionSyntax` hook, matching how this file already gates language-varying behaviour (`stripReceiverCastExpressions`, `hoistTypeBindingsToModule`). Shared pipeline code names no language. - `bare: true` — Python - `keyword: 'new'` — JS/TS, Java, C# - `selector: 'new'` — Ruby, including the parenthesis-less `Service.new` spelling that reaches the chain walker rather than the call branch Opt-in is per-language for two reasons. Correctness: `bare` would mistype `stat(&st).field` in C, where a struct and a function may share a name. Evidence: PHP, Swift, Dart and Kotlin resolve this shape already, so they stay unwired instead of carrying a declaration that changes nothing — each verified by diffing analyzer output between builds with and without the change, not assumed. The keyword gate also keeps a bare factory call honest: in a `new` language, `makeOther(db).doWork()` still resolves through the factory's return type and is never read as constructing a same-named class. Tests: TypeScript fixture (inline `new`, a plain `.js` file for the javascript provider, two-step, and the factory guard) and a Ruby fixture (`Service.new` with and without an argument list, plus two-step). With the source change stashed, the inline cases fail and the factory/two-step cases still pass. The Python cases from the first commit are unchanged. No Kotlin fixture: its cases passed without the change, so they would document coverage this commit does not provide. Full `test/integration/resolvers` + `test/unit/scope-resolution`: 4234 passed, 1 skipped. Ruby captures golden regenerated — additions only, no existing digest changed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RqnsJK3Cnbu3bjdZbzgMMP * fix(resolution): only treat a construction selector as construction on the class itself (#2708) The `selector: 'new'` rule fired on any receiver whose type was class-like, which is true both when the receiver IS the class constant (`Factory.new`) and when it is a value of that class (`factory.new`). `isClassLike(...)` cannot tell those apart, so an instance receiver took the construction path too and skipped the member lookup that should have run. That replaced a CORRECT edge with a wrong one. Measured against the base build on a class defining an instance method `new` returning a `Product`: factory = Factory.new; factory.new.run before this PR: Product#run (correct) after this PR: Factory#run (wrong) Track whether resolution currently sits on the class constant or on a value of that class, and apply the selector rule only to the former. The head of a chain is a class constant only when it resolved straight to a class binding rather than through a typeBinding; every hop past it yields a value, so the flag clears. The `obj.method()` branch derives the same fact from whether `objExpr` is a bare name resolving to that class. `Factory.new.run` keeps the behaviour this PR introduced (Factory#run), which is itself a fix over the base build's Product#run. KNOWN LIMITATION, now documented on the contract field and asserted by a test so a future change to it is deliberate: a class-level override (`def self.new` returning another type) is still read as construction. The scope model records no staticness per member, so `def new` and `def self.new` are indistinguishable at this layer; separating them needs the language provider to record staticness first. An earlier attempt to use `TypeRef.source` as a proxy was abandoned after tracing showed Ruby records body-inferred return types as `return-annotation` too, so it does not discriminate. Tests: `ruby-construction-selector` fixture pins all three shapes — class constant, instance receiver, and the documented class-level-override limitation. Ruby resolver suites: 185 passed.

Retry the lookup on the base name via `stripTemplateArguments` — the same normalization `resolveClassBindingForName` already applies to typed receivers in the sibling `receiver-bound-calls` pass. The exact-name lookup still runs first, so a class whose name legitimately contains `<` is unaffected. Measured on the probe that first showed the gap: before: | viaGeneric | Class:src/box.ts:Box | (construction edge only) after: | viaGeneric | Method:src/box.ts:Box.get#0 | (member edge resolved) Tests: `viaGenericCtor` added to the typescript-inline-constructor-receiver fixture, asserting both the target file and that the resolved id is `Box`.

The chain walker seeds its starting class from the head segment, which arrives as `new Service(db)` and reduces via `stripCallParens` to `new Service` — no binding and no class of that name, so the walk was never seeded and every segment after it resolved to nothing. Seed the head through the same construction rule the call branch already uses. A constructed value is an instance, so the class-constant flag from the previous commit correctly stays false — `new Factory().new` does not get the selector treatment. The gap was asymmetric across the languages this PR wires: Python's bare form strips to a plain `Service` and was already seeded, so only the keyword languages were affected. Tests: `viaChainHead` added to the typescript-inline-constructor-receiver fixture. Note the fixture annotates `readonly inner: Inner` explicitly — with an unannotated initializer the walk stops at the field, which is field-type inference and a separate concern from head seeding.

Any other trivia the source used — a tab, a line break — failed the match and the member-call edge was lost. Match the keyword as a whole token followed by one or more whitespace characters instead. `newService()` still fails the match, which is the point: it is an ordinary call, not a construction, and must keep resolving through its own return type. The keyword is escaped before it enters the pattern. It comes from a language provider rather than from user input, but a keyword containing a regex metacharacter would otherwise build a silently wrong pattern. Tests: tab-separated and newline-separated `new` added to the typescript-inline-constructor-receiver fixture. Note these cases only survive because `gitnexus/test/fixtures/` is listed in the repo-root `.prettierignore` — running prettier from inside `gitnexus/` does not pick that file up and normalizes the tab away.

The call branch splits the callee at its last `.` before construction is considered, so a qualified type name was routed into `obj.method()` resolution as if `ns` were a receiver and `Service` a member. A keyword-marked expression is never a member call, so resolve it as construction before the split. The callee lookup now also handles a dotted name: an unambiguous `qualifiedNames` match first, then the trailing simple name, mirroring how receiver resolution elsewhere in this pass degrades. Measured: before: | viaQualified | Class:src/svc.ts:Service | (construction only) after: | viaQualified | Method:src/svc.ts:Service.doWork#0 | Bare-form qualified construction (Python `models.User(db).save()`) is NOT addressed here: that shape currently emits no edges at all, including no construction edge, so it is a namespace-import resolution gap upstream of this pass rather than a construction-typing one. Tests: `viaQualifiedCtor` added to the typescript-inline-constructor-receiver fixture.

Measuring both ways shows it never did: Java resolves `new Svc().doWork()` identically with and without the change, because `java/captures.ts` (#2564) already rewrites an `object_creation_expression` receiver to the constructed type's simple name, so the raw `new Svc()` text never reaches this resolver. The decisive evidence is generics: Java resolves `new Box<User>().doWork()`, which the keyword path could not do before the template-argument fix earlier in this series — the resolution demonstrably comes from the capture rewrite, not from here. Removing the declaration rather than leaving it as defensive configuration: an unreachable per-language opt-in reads as coverage that does not exist, and the contract now records why Java is excluded so the omission is not mistaken for an oversight. Verified after removal: the Java probe still resolves both the inline and two-step spellings, and the Java resolver suites pass (252 passed, 1 skipped). An earlier coordinator measurement in this review claimed Java WAS broken on base; that comparison was invalid (the "without fix" build had not been rebuilt). Corrected here.

Both sites ask the identical question, so they now call one `isConstructionSelectorHop` predicate, and the doc comment says what is actually true. `ResolveCompoundReceiverOptions.constructionSyntax` re-declared the contract's object shape by hand. It was the file's first object-shaped duplicate, and because the value arrives as a non-literal variable, TypeScript's excess property check would not fire: a sub-field added to the contract later would type-check and then be silently ignored here. It is now derived with `ScopeResolver['constructionSyntax']`.

C# had no fixture despite being the only keyword-wired language whose behaviour genuinely depends on the construction rule — measured absent on base and present on head. `csharp-inline-constructor-receiver` covers the inline spelling, the two-step spelling, and a static factory that must keep resolving through its return type rather than being read as construction. The TypeScript two-step assertion checked only `toContain('Service')`, and the same fixture defines `LegacyService` — `'LegacyService'.includes('Service')` is true, so the assertion could not distinguish the two targets. It now pins `targetFilePath` the way its sibling assertions already do. Nothing guarded the deliberate opt-in set, so an accidental wiring of a language that already resolves the shape, or a silent loss of one that needs it, would pass the whole suite. `construction-syntax-wiring.test.ts` pins the inventory in both directions: exactly which languages declare `constructionSyntax` and with which spelling, and that java/php/swift/dart/ kotlin stay unwired.

That is precisely the class of change the version-history block in this file requires a bump for, and the reuse gate is a strict equality on the persisted stamp. Without it, every existing v22 index passes the gate on the next `analyze` — or is served by the same-commit "already up to date" fast path — and keeps returning the pre-fix graph for unchanged files. `impact(direction: "upstream")` and `context()` would go on omitting the very callers #2708 is about, with no warning, until something unrelated forced a full re-analyze. The fix would have shipped without reaching anyone who already had an index. Precedent is unbroken across the recent resolution PRs: #2723 → v22, #2699 → v21, #2695 → v20, #2563 → v14, each with its own rationale paragraph. This adds v23 in the same form.

Neither script writes the baseline itself — running without `--check` only prints, and the file is edited deliberately, which is what its own comment asks for. Regenerated, last in the series so the fixture set was final: bench/python-scope/baseline-fingerprint.txt 36e29abc… -> f120df92… bench/scope-capture/baselines.json ruby 070e4e11… -> fea3edf8… typescript 281e9548… -> cad25be9… csharp e05dc274… -> 05a85bae… CI only ever reported the python drift, because the benchmarks job runs the python step first and aborts there; the cross-language step never ran. Both were verified locally after the update: [measure --check] PASS (capture fingerprint + scaling) [import-target-fingerprint --check] PASS (resolver fingerprint) [scope-capture --check] PASS (15 languages) The `csharp` and `ruby` entries moved because of the fixtures added earlier in this series, not the original ones — a reminder that this baseline moves with any fixture addition, not just the one that first triggered it. Captures goldens regenerated alongside (csharp, ruby); both additive only, no existing digest changed. The python golden did not move: no `python-*` fixture was added after its last regeneration.

Gergő Magyar	df06529950	fix(rust): resolve module-qualified calls against the module tree (#2730) (#2741) ... * fix(rust): resolve module-qualified calls against the module tree (#2730) A Rust call written with a path (`tools::dispatch(..)`) was captured with only its tail identifier, making it indistinguishable from a bare `dispatch(..)`. The scope-chain walk then resolved the bare name lexically and bound it to whatever `dispatch` was nearest — which, for the common wrapper idiom fn dispatch(..) -> ToolOutcome { tools::dispatch(..) } is the wrapper itself. The graph gained a self-loop, the real cross-module edge never existed, and `impact` reported the callee as unreached: the issue's repository showed its central tool dispatcher as `risk: LOW` with 0 affected processes and both "callers" being `#[cfg(test)]` functions, while still labelling the result `epistemic: "exact"`. Resolve paths the way rustc does, over the module tree rather than the filesystem: - `mod_item` now emits `@declaration.namespace`, so a Rust module is a named definition rather than an anonymous scope region. This mirrors the existing C++ `namespace_definition` capture and lets the shared `tagNamespacePrefixes` pass stamp members with their enclosing module path — that pass needed no changes to start working for Rust. - `module-path.ts` reconstructs the other half of the tree: crate roots are directories holding `main.rs`/`lib.rs`, and a file's module path is its location below that root. A definition's module is its file's module plus any enclosing `mod` blocks. - `crate::`, `self::` and `super::` are prefix transforms on the calling module, not reasons to stop resolving. - The final path segment is looked up as a member of the resolved module, including members it only re-exports. A `pub use` creates no binding on the re-exporting module's own scope, so re-exports are followed through that module's import edges. Resolution runs ahead of the implicit-`this` and scope-chain tiers, so an explicit path outranks a lexical shadow, and returns undefined on an unknown module, a missing member or a tie — leaving the existing chain untouched. The new `ScopeResolver.resolveQualifiedFreeCall` hook is optional and unset for every other language, so this is additive. Fixes the reported case (direct callers 2 -> 3, impacted 2 -> 6, the Agent module now visible) plus multi-segment paths, `super::` paths and `pub use` facades, each of which previously produced a wrong edge. Known limitation, pre-existing and unchanged by this commit: an inline `mod inner { fn dispatch }` and a crate-root `fn dispatch` in the same file collapse to one graph node, because node identity is `<file>:<qualifiedName>` and does not carry the module path. That is a separate defect requiring module-path-qualified node ids and an incremental-schema migration.

Both are additive, so every bench fixture holding a `mod` block or a `Foo::bar()` call gains capture groups, and the corpus grew by the three `rust-2730-*` fixtures. Only the Rust fingerprint moves. The other 14 languages are byte-identical, which is the intended blast radius for a language-local capture change. Scaling stays linear at 1.043, well inside the 1.5 budget. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01J5nWP4BFeBSjbQ3uqAjtxV * fix(rust): carry crate identity in qualified module paths (#2741 review H1) A module was identified by its path segments below a crate root, so `crates/alpha/src/tools.rs` and `crates/beta/src/tools.rs` were the same module. A cargo workspace routinely gives several members the same internal module name — `util`, `error`, `config`, `types` are near-universal — and that made qualified resolution do one of two wrong things: - where only one member defined the called name, the call bound ACROSS crates; - where both defined it, the lookup saw two candidates, refused, and handed the site back to the lexical walk that emits the same-name self-loop. The fix for #2730 therefore switched itself off in exactly the workspace layouts it was written for, and #2730's own reported reproduction repository is multi-crate. A module is now `{ crateRoot, segments }` and `sameModule` compares both. Rust has no implicit cross-crate paths — reaching another crate requires naming it — so two modules in different crates are never the same module. Anchored paths (`crate::`, `self::`, `super::`) resolve inside the caller's own crate and inherit its root. Covered by a two-member workspace fixture where both crates define `tools::dispatch` behind a same-name wrapper, plus unit tests for the path arithmetic itself, including the branches no fixture reaches (a file under no crate root, a `super::` chain walking above the crate root). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01J5nWP4BFeBSjbQ3uqAjtxV * fix(rust): count only module members when resolving a qualified call (#2741 review H3) Module membership was inferred from the file path alone, so any callable in the right file counted as a member of the module. A `fn` nested inside another `fn` has the same `filePath`, the same bare `qualifiedName` and no owner, making it indistinguishable from a module-level item: pub fn dispatch() -> usize { 3 } // the real member pub fn wrapper() -> usize { fn dispatch() -> usize { 99 } // counted as a second member dispatch() } Two candidates tie, the lookup refuses, and the call falls back to the lexical walk that emits the same-name self-loop — so an unrelated local helper anywhere in a module silently reinstated #2730 for every qualified call into it. The scope model already draws the line exactly: a module-level item is bound with `origin: 'local'` in its module's own scope, a function-local item binds in the enclosing Block, and an `impl`/trait method binds in the Class scope. Membership is now that binding lookup rather than a path comparison. Inline-`mod` members bind in their Namespace scope rather than the file's Module scope, and reaching it would mean walking every child scope — faulting them back in from disk on the out-of-core path. They keep being identified by the `namespacePrefix` the shared tagging pass stamps on them, which a file-module member never carries. The documented residual is a `fn` nested inside a `fn` inside an inline `mod`, which inherits that prefix; that is strictly smaller than before and costs a refusal, never a wrong edge. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01J5nWP4BFeBSjbQ3uqAjtxV * fix(rust): require a use-binding to name a module, not a type (#2741 review H2) Import resolution deliberately strips a trailing symbol segment when probing for a file — "the last segment might be a symbol (function, struct, etc.), not a module. Strip it and try again" (import-resolvers/rust.ts). So `use crate::client::ClientBuilder;` also resolves to `client/mod.rs`. The qualified-call resolver took that at face value and treated the imported TYPE as the module `client`. Rust impl methods carry a bare `qualifiedName`, so `ClientBuilder::new()` was then looked up among `client`'s module members and bound to an unrelated module-level `new` — turning an unresolved site into a false edge, which the module's own contract calls the worse outcome. A binding now has to name the module it resolved to. The edge's `targetExportedName` is the tail of the written path, so comparing it against the resolved module's own tail separates the cases exactly: use crate::tools; tail `tools` module ['tools'] accept use crate:🅰️:b as tools; tail `b` module ['a','b'] accept use crate::tools::{self, Ctx}; tail `tools` module ['tools'] accept use crate::client::ClientBuilder; tail `ClientBuilder` module ['client'] reject Covered by a fixture where `client/mod.rs` deliberately holds both `impl ClientBuilder { fn new }` and a module-level `fn new`, so a regression re-binds to the wrong one, plus a control asserting a genuine `client::new()` module qualifier still resolves.

Each is a separate crate with its own `crate::` root, and its submodules live under `src/bin/<name>/`. Only `main.rs` and `lib.rs` established a crate root, so those entry files were folded into the surrounding library and given the invented module path `bin::<name>`. That made `crate::helper()` inside a binary resolve into the LIBRARY's `helper` — and unlike the other findings in this review, this one downgraded an edge the lexical walk had previously resolved correctly, so it made existing output worse rather than merely failing to improve it. `src/bin/<name>.rs` is now its own crate root (as is the `src/bin/<name>/main.rs` directory form), so a binary's modules and the library's modules of the same name are no longer the same module.

That let file layout outrank a real import: with `use crate::b;` in `src/a/mod.rs` and an undeclared — or `cfg`-gated — `src/a/b.rs` present on disk, `b::f()` bound to the sibling file, where rustc resolves it to `crate::b`. A `mod` declaration, inline or file-backed, emits a `Namespace` def bound locally in the declaring scope, so the candidate is now gated on that binding rather than assumed. When the caller does not declare the submodule the candidate is skipped and the `use` and crate-root channels still run, so this only removes guesses. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01J5nWP4BFeBSjbQ3uqAjtxV * fix(rust): follow only real re-exports, and refuse on an ambiguous one (#2741 review) Two problems in the re-export channel. A private `use` was followed as though it re-exported. `use crate::tools::helper;` makes `helper` visible INSIDE the module; it does not put it on the module's public surface, so `facade::helper()` does not compile. Only `pub use` does, and finalize already distinguishes them — `reexport` for `pub use`, `named` for a private one. The `alias` kind is now accepted alongside `reexport`, because `pub use x::y as name` is a re-export that was previously ignored entirely. The lookup also took the first matching edge in file-iteration order, which is parse-pool order. Two `cfg`-exclusive facades re-exporting the same name are indistinguishable at this layer, so picking one baked a coin flip into the graph. It now refuses on a genuine tie, consistent with how member lookup already behaves. The pre-existing limitation that only FILE modules are reachable — a `pub use` inside an inline `mod facade { … }` has no `moduleScopeByFile` entry — is now stated in the code. Reaching those would mean walking every child scope and faulting the scope tree back in from disk, which is the cost that index exists to avoid; a miss falls through to the unchanged chain rather than guessing. The regression test deliberately makes the re-exported name globally ambiguous. Without that, the pre-existing unique-global free-call fallback resolves the call on its own and the assertion passes whatever this channel does.

Each one ran the full candidate search before returning undefined, and every candidate that missed then walked all of `workspaceIndex.moduleScopeByFile`. Total cost grew as `qualified-call-sites x files`; two independent measurements put per-site cost at 0.117 -> 0.428 ms across 301 -> 1201 files, i.e. linear in workspace size. Two changes: - The module index now carries a flat set of every module segment name in the workspace, and a qualifier whose head matches none of them is rejected before any candidate work. Measured at 0.02 us per rejected call and flat in file count (500 -> 8000 files), against a previously linear per-site cost. - Module scopes are indexed by module identity once per pass rather than rediscovered by scanning every file per candidate. On the out-of-core scope index that scan was worse than CPU: `moduleScopeByFile` fetches through `scopeTree.getScope`, so a full sweep could fault every module scope back in from disk — the pattern `workspace-index.ts` added `exportedCallableByName` to avoid. Given the #2649 and #1871 history this mattered before merge. The captures golden is regenerated for the fixture files added earlier in this series; `emitRustScopeCaptures` itself is unchanged by this commit.

The incremental write set only covers CHANGED files, so a top-up against a pre-v23 index keeps the wrong self-loop — and keeps reporting the callee as unreached — for every unchanged Rust file. The constant's own doc block states this rule, and the precedent is exact: v11 is the same file (`rust/query.ts`) gaining a capture that changes CALLS edges, with the same "force a full re-analyze" contract, and v12 is a second Rust instance. `SCHEMA_BUMP` 30 -> 31. `@declaration.namespace` and `@reference.qualified-name` are parse-time captures, so a warm parse cache replays the old capture set verbatim: `rawQualifiedName` comes back undefined and no Namespace def exists to hang a module prefix on, turning the entire resolution tier into a no-op on unchanged files. `PARSE_CACHE_VERSION` folds in the package version, so a tagged release would have invalidated eventually — but source, dev and CI builds at the same version would not, and the v29 note already warns that relying on someone else's bump is how a change ships with no invalidation at all. Re-checked against origin/main at commit time, as that note instructs.

That is right for C++ and C#, where the qualified name genuinely carries the namespace. Rust qualified names never do, so the guard fired on a coincidence: in `mod a { pub fn a() }` the member's name equals its module's name, the prefix was skipped, and `moduleOfDef` then reported the member as belonging to the PARENT module. `crate:🅰️:a()` refused, and the def became indistinguishable from a crate-root `fn a` for the module matcher. The guard is now conditional on a `qualifiedNamesCarryNamespace` option that defaults to the existing behaviour, and Rust opts out. The shared pass stays language-neutral — the decision lives with the provider that knows what its own qualified names contain. C++ and C# resolver suites pass unchanged alongside the Rust ones (600 tests).

The path split filtered the empty leading segment away, which silently reinterpreted the path as relative and let it resolve against a local module that happens to share the name. Extern crates are outside the workspace module tree, so the qualified tier now refuses and leaves the site to the unchanged chain. The regression test asserts the tier does not bind into the local `tools` module, rather than asserting no edge at all: the lexical tier still resolves the bare tail on its own, and that behaviour is not what this change governs. Asserting an empty edge list would have been testing a different tier.

Two copies of the same set drift: extending the canonical one with a new callable kind would silently leave qualified calls of that kind unresolved here, with nothing to catch it. Use the shared predicate. The trailing `export { moduleOfFile, moduleOfDef }` and `export type { ScopeResolutionIndexes }` were commented as being "for the resolver's unit tests". No test imports them: the only importer of this module anywhere in src or test is `rust/scope-resolver.ts`, which takes just `resolveRustQualifiedFreeCall`. Both functions are already exported from `module-path.ts` (where the new unit tests take them from), and `ScopeResolutionIndexes` is canonically exported from `model/scope-resolution-indexes.ts`. Removed rather than left as surface that implies a contract it does not have.

The true pre-PR value on the base commit is `7f1240b3…`. CI could not catch it: the gate compares the live fingerprint against the stored one and never reads the prose, so the audit chain these notes exist to provide was broken with nothing to flag it. The note now carries the correct prior value, and the fingerprint is regenerated for the fixtures this review series added. Scaling 1.061, well inside the 1.5 budget; fixture_count 196; the other 14 languages remain byte-identical.

It moves with every bump by design — that pin is what stops an id- or edge-changing commit shipping without invalidation. Updated for the bump to 23, with the pre-v23 case added to the reuse-gate table: a v22 index predates Rust module-qualified call resolution, so every unchanged Rust file would keep the same-name self-loop and keep reporting the real callee as unreached. Caught by CI rather than locally, because the earlier sweeps in this series covered `test/integration/resolvers/` and `test/unit/scope-resolution/` only — the pin lives outside both.

This is the residual half of the defect JS/TS block scopes narrowed in #2695. Blocks moved nested-block locals off the chain of a reference outside the block, which removed 114 false edges; a local declared directly in the function body stayed on it, and no amount of extra scopes reaches that case. Fixed at the cause instead: `recv.name` names a member of whatever `recv` denotes, so a binding of the bare tail name in an enclosing scope is never the right answer. Steps 2 and 3 (receiver type / owner members) are the legitimate routes. `this` and `self` are EXEMPT, and that exemption was measured, not assumed. Skipping Step 1 for every explicit receiver removed 711 edges on a 762-file corpus — but 2 of those were genuine: `self.srcIx` and `self.streamedAt(...)` after `const self = this`, reaching their own class's members through the class-body scope. For a self-receiver the members and the lexical chain legitimately overlap; for a named receiver they never do. Exempting the self names keeps both true edges and still removes 709 false ones, adding none. The removals were classified by reading source at the site, not by pattern- matching ids — an "is the target a member of the source's owner?" heuristic labelled 43 of them plausible and every one I then read was false: language = config.language; -> the class's own `language` dirMap.get(...) / exactMap.get(...) -> a sibling object-literal `get` return config.extractVisibility(n); -> the class's own method (self-edge) writer.close(); -> GraphEmitSink.close Residual, deliberately kept: a `this.x` read can still bind lexically to a same-named local. That is the price of the two true self-alias edges above. `INCREMENTAL_SCHEMA_VERSION` 19 -> 20: a v19 index holds these false CALLS/ACCESSES on every unchanged file and would keep serving them through the reuse gate. Test confirmed discriminating: it fails with the guard reverted.

Same defect shape as the `var` case #2693 already fixed: a different grammar node for the same construct, and the resulting graph node was not callable. Adds the four variable-binding shapes in both languages: `const`/`let` and `var`, each plain and exported. Purely additive — no existing pattern is reordered or rewritten, because the #2687 pre-scan dedup is order-dependent and collapsing the value/callable pair depends on which match wins. Deliberately NOT covered, and the query comment says so: a generator in an object-literal pair or a HOC wrapper still falls through anonymous. Those are rarer, and each additional pattern is another chance to disturb the dedup. `SCHEMA_BUMP` 26 -> 27: definition captures are parse-time, so a warm parse cache would replay the old ones verbatim — `--force` does not clear it. Two tests confirmed discriminating (they fail with the patterns reverted), plus a guard that the already-working generator DECLARATION form is unaffected, since it shares the emit path these were inserted beside. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0184RmD24KFJidYqpM7v3XjR * fix(ingestion): keep caller attribution in lockstep with definition ids (#2699) The definition phase appends `localIdentity` to a nested callable's own name segment (`run.save@3:2`); `findEnclosingFunctionId` did not, so the two phases derived different ids for the same callable. The failure mode is silent — the caller id names a node that does not exist, so the edge is dropped rather than reported — which is why the parse-worker docblock calls this pair a lockstep guarantee and asks that both phases derive the prefix from one place. The condition is now byte-identical to the definition phase's (`nestedPrefix !== undefined`), so the two cannot diverge again. Scope of the claim, stated plainly: no reproducing case was found, and this changes nothing measurable on a 762-file TypeScript corpus. TS/JS resolve callers through `resolveCallerGraphId` in the graph bridge, not this path; `findEnclosingFunctionId` serves the `callExtractor` languages, and the corpus does not exercise a nested callable there. The review that raised it (P3) observed zero dangling edges, and "zero dangling" is also what silently dropped edges look like — so this closes a documented contract rather than a demonstrated bug, and carries no test of its own. Rides the `SCHEMA_BUMP` 26 -> 27 in the preceding commit: caller attribution runs in the worker, so a warm parse cache would replay the old ids.

The file header still described `lookupCore` Step 1 as walking the lexical chain for EVERY lookup, and called the function-body-local case "unchanged and still mis-resolves ... pre-existing and tracked separately". Commit 59b892ca in this same PR falsified both, and the describe block added ~80 lines lower in this same file asserts the opposite — a reader scoping future work from the header would have concluded the case was still open. Rewritten to state what the code does: Step 1 is skipped for a NAMED explicit receiver, the function-body case is fixed here, and the surviving residual is that a `this`/`self` read can still bind lexically to a same-named local — with the reason those two names are exempt (they keep the genuine `const self = this; self.member` reads that Step 1 resolves correctly). Also corrects a PRE-EXISTING staleness inherited from #2695 in the same paragraph block: "the genuine bare read of that same local must still emit its edge" describes a test that no longer exists, because TypeScript emits no `@reference.read` for bare identifiers at all. Fixed here rather than left adjacent to a freshly corrected sentence. Comments only — `detect_changes` reports 0 changed symbols across 1 file.

The plan called for a unit test asserting the two id-derivation phases agree. Two things changed that plan during execution, both recorded here. FIRST — there are THREE phases, not two. Re-verifying the plan's assumption (`grep -n localIdentity`) found a third call site: the worker-path node-id derivation in `processFileGroup` (parse-worker.ts:2316), whose own comment already acknowledged the coupling. `impact` on `localIdentity` corroborates: three direct dependents, all in the Workers module. So the invariant three phases must agree on is now ONE function, `nestedCallableQualifiedName`, and divergence requires deleting a call rather than editing a duplicated expression. SECOND — the planned `_forTest` alias seam does not work for this module. `parse-worker.ts` posts a `ready` message to `parentPort` at module scope, so value-importing it from a unit test throws before any test runs; the existing unit tests that reference it use `import type` only, which erases. The rules therefore move to a new pure module, `workers/callable-id.ts`. That is what makes them testable at all, rather than merely commented. Pure refactor — no id changes. Verified by the suites that assert exact node ids (`Function:svc.ts:run.save@7:2`, `Function:c.php:run.$save@3:2`): 74/74 green, and `detect_changes` reports only the three expected symbols and the two `processFileGroup` flows `impact` predicted. The test pins both halves: the rule's contract, and a structural assertion that no site has re-inlined `${prefix}.${localIdentity(...)}` — the unit assertions alone would still pass if a fourth phase spelled the rule out by hand, which is exactly how the divergence arose. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0184RmD24KFJidYqpM7v3XjR * fix(scope-resolution): give PHP's `$this` the same self-receiver exemption (#2699) Review finding (LOW). The Step-1 skip added in this PR exempts `this`/`self`, but the receiver name arrives as the reference node's RAW SOURCE TEXT — `extractExplicitReceiver` returns `cap.text` verbatim — so PHP's `$this->x` presents as the string "$this" and matched neither entry. PHP was the one supported language whose self-receiver got no exemption at all. Measured, and the measurement is why this is framed as consistency rather than a bug fix: - Corpus delta ZERO. 762-file TypeScript corpus, CALLS+ACCESSES set diff: 13179 -> 13179, added 0, removed 0. So no INCREMENTAL_SCHEMA_VERSION bump (stays 20), per the plan's decision rule. - No PHP shape found that DISCRIMINATES. Both the simple `$this->prop` / `$this->helper()` shapes and a closure reading `$this->…` inside a method that also declares a same-named local produce byte-identical edge sets with `$this` present and absent — Step 2 resolves the receiver's type first. The added test is therefore labelled a COMPANION INVARIANT, exactly as the `this.baseUrl` case beside it is, and does not claim to prove the fix. It is still worth making: the exemption is protective, and the 709-removed / 0-true-lost measurement that justified the narrow guard was TypeScript-only, so PHP's safety was never established by evidence. This closes that by construction. Two corrections to what the plan assumed, both found by checking: - The plan (and my first draft of this comment) claimed the codebase had no precedent for handling a sigil'd receiver name. FALSE: `THIS_RECEIVERS` in `core/ingestion/type-env.ts:244` has always listed `$this`, and it is the ingestion-side twin of this very list. The precedent does not merely exist, it validates the approach chosen here — list the spelling as data, do not strip sigils. - That twin also lists `Me`. Deliberately NOT mirrored: no entry in `SupportedLanguages` is Visual Basic, so it could only ever exempt a variable that happens to be called `Me`. The two lists are otherwise the same set with nothing enforcing it — a fifth instance of the twin-list drift class this PR keeps meeting. A drift guard is the right fix and is out of scope here; noted for follow-up.

The fixture calls `fresh.validate()` where `let fresh = Self { .. }` inside `impl User` — a genuine call to `User::validate`, and a TRUE edge that the skip deleted. Root cause is a twin-channel disagreement, not the skip: - `type-extractors/rust.ts:142` substitutes `Self` -> the enclosing impl type into the TYPE-ENV channel via `findEnclosingImplType`. - `languages/rust/interpret.ts` recorded `@type-binding.type` verbatim, so the SCOPE-RESOLUTION channel bound `fresh: Self` — a type that does not exist, leaving the receiver's type unknown and Step 2 unable to resolve. `main` passed only because Step 1 still walked the lexical chain for named receivers: the impl scope binds `validate` by name, so the call resolved BY ACCIDENT. Stopping that walk turned a latent gap into a lost edge. The fix closes the gap rather than restoring the accident — `Self` is now substituted at capture-emit time in `languages/rust/captures.ts`, where the impl node is reachable, reusing the `findEnclosingImpl` + `syntheticCapture` idiom already in that file. CORRECTION to this PR's central claim. "709 removed / 0 added / 0 true edges lost" was measured on a 762-file TYPESCRIPT corpus and stated without that qualifier. Rust lost one true edge. The measurement stands for TypeScript; it did not generalise, and the PR body is being updated to say so. Scope of the breakage, measured rather than assumed: 1 failure in 2927 tests across all 51 resolver files. Every other language — Go, Java, C#, Kotlin, Swift, Python, PHP, Ruby, Dart, C++ — passes, which is why this is a targeted fix and not a revert of the skip. Re-baselined `bench/scope-capture` for RUST ONLY (655aed01 -> 7f1240b3); the other 14 language fingerprints are byte-identical. The drift is the intended output change and the reason is recorded in the baseline entry, per that file's own "explain, never re-baseline to make CI green" rule. Verified: rust resolvers 192/192; all 51 resolver files 2926 passed / 1 skipped / 0 failed; the 8 targeted suites 96/96; all 8 CI bench gates PASS; `tsc --noEmit` clean; `detect_changes` reports one touched symbol (`emitRustScopeCaptures`) and no affected flows.

They drifted for OPPOSITE reasons, so each was inspected before regenerating rather than refreshed on sight. RUST GOLDEN — drifted because 5f55fe46 CORRECTS the output. A `Self` type binding now records the enclosing impl's type instead of the literal `Self`, in both the `let x = Self { .. }` and `fn new() -> Self` forms. Blast radius verified exact: 5 fixtures drifted, all 5 contain `Self`, and every `Self`-bearing rust fixture is among them (rust-self-struct-literal, rust-constructor-type-inference, rust-default-constructor, rust-method-enrichment, rust-scoped-multi-file). C# PDG SNAPSHOT — drifted because the named-receiver Step-1 skip (59b892ca) REMOVED A FALSE EDGE. CALLS 7 -> 6, and the edge that went is: Demo.Resolve.Parse@142:12#1 -> Demo.Resolve.Parse@142:12#1 a self-call, from `int Parse(string v) => int.Parse(v);`. `int.Parse(v)` is System.Int32.Parse; the lexical chain was binding it to the enclosing local function that happens to also be called `Parse`. Same defect class as `writer.close()` -> GraphEmitSink.close. The snapshot's own comment says it exists so "a future refactor that silently rewires the C-family graph trips this gate" — it tripped correctly, and the rewiring is an improvement. Both failures were PRE-EXISTING on this PR from 59b892ca, not from the three commits above it — verified by reverting those and reproducing unchanged. They went unseen because this PR's CI was never watched after its first push. Verified after regeneration, WITHOUT update flags so they must genuinely pass: rust-captures-golden 9/9; pipeline-pdg 31/31. The snapshot diff is 3 lines, all inside the C# entry — no other language's snapshot moved. `detect_changes` reports 0 changed symbols (test artifacts only).

Gergő Magyar	170805647c	fix(rust): keep duplicate type names ambiguous in range binding (#2514) (#2652) ... * fix(rust): latch duplicate type-name ambiguity in range binding (#2514) The range-binding prepass tracked cross-file return and field types in two maps and used map presence itself as the ambiguity flag: the second definition of a name deleted it, but a third definition found it absent and re-inserted the last-scanned file's type. Odd duplicate counts (3, 5, ...) therefore resolved a genuinely ambiguous name to whichever file was scanned last, while even counts stayed ambiguous. Latch ambiguity in a dedicated Set per registry (ambiguousReturnTypes, ambiguousFieldTypes): once a name has two or more workspace definitions it never resolves again, regardless of duplicate count or file order. Adds integration coverage for two/three-duplicate functions and structs, permuted file order, and a unique-name over-suppression guard. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(rust): bump INCREMENTAL_SCHEMA_VERSION to 12 for the #2514 range-binding fix The duplicate-name ambiguity latch changes which cross-file Rust CALLS edges the range-binding prepass emits. The incremental writeback persists only changed-file nodes, so an incremental top-up against a pre-v12 index would keep the old spurious edges on every unchanged Rust file. Bump the schema version to force a one-time full re-analyze, matching the v7/v11 contract for edge-affecting resolver changes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(rust): resolve import-disambiguated duplicate types in for-loops & destructuring Follow-up to the #2514 ambiguity latch. When several modules define the same function/struct name and a call site disambiguates it with a `use` import (including aliases and `use x::*` globs), range-binding now resolves the for-loop element type and the destructured field type to that specific imported definition, instead of leaving it unresolved. The bare-name return/field maps are (correctly) ambiguous for duplicates, but the call site's import pins a definition. range-binding records the full, untruncated return/field type per defining file, and resolveImportedDef() resolves a name to the single in-scope definition, mirroring Rust name resolution: - tier 1: explicit `use`/re-export imports and local defs (lookupBindingsAt); these shadow globs, so if any exist we decide within them alone; - tier 2: glob imports, consulted only when tier 1 is empty; a `wildcard-expanded` ImportEdge names the target module, so we resolve only when exactly one glob-target file actually defines the name. Two or more visible definitions stay unresolved, preserving the #2514 latch. normalizeRustReturnType is untouched (its Vec<T> -> Vec truncation is load-bearing for receiver resolution), so the full generic is read from the per-file map instead. Covered by integration tests: explicit / aliased / single-glob imports resolve to the imported definition; two globs that both export the name stay ambiguous; a local definition shadows a glob; no-import duplicates stay unresolved (#2514). INCREMENTAL_SCHEMA_VERSION stays at 12 (bumped by the #2514 commit in this PR); its note now also covers these added resolution edges. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * perf(rust): parse each file once in range-binding when the workspace fits a budget populateRustRangeBindings makes two passes over every file and, because the shared treeCache is empty in the analyze flow, re-parsed each file in both — a workspace of N files paid 2N parses. It now parses each file once and reuses the tree across both passes via an in-function store, gated by a source-byte budget: workspaces up to 16 MiB of Rust source (essentially every real repo) reuse trees; larger ones fall back to per-pass re-parsing so peak RSS stays bounded on huge repos (the memory-sensitive case keeps its current profile). Also collapses the parse+timeout boilerplate that was copy-pasted in both loops into one getOrParseTree helper, and adds a PROF-gated `rangeBind=` segment to the scope-resolution profiler for phase-level observability. Measured on a 500-file synthetic Rust workspace (PROF_SCOPE_RESOLUTION=1): the range-binding phase drops ~370ms -> ~320ms (~14%), parses 1000 -> 500. Behavior is unchanged (199 rust + range-binding-order + parse-timeout tests green); repos above the budget are unaffected. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(rust): update schema-version gate to v12; regenerate golden + bench baseline for new fixtures CI surfaced three deterministic-artifact failures, all from this PR's own additions: - call-summary-schema-version.test.ts hardcoded INCREMENTAL_SCHEMA_VERSION === 11 (the #2604 window); #2514 bumped it to 12. Update the gate and extend the reuse-gate version history so a v11 stamp now forces a full re-analyze. - rust-captures-golden expected-captures.json drifted (130 -> 174 entries) because the new rust-import-* / rust-dup-* fixtures joined the rust-* corpus. Regenerated (UPDATE_GOLDEN=1): additions only, no existing captures changed — emitRustScopeCaptures is untouched. - bench/scope-capture/baselines.json rust fingerprint drifted for the same reason. Rebaselined with a provenance note; scaling 1.06 < 1.5 budget.

The existing rust-abstract-dispatch fixture was NOT extended for this, deliberately: it already has other callers referencing the same method names (process()'s repo.find()/save()/count()), and an existing resolution fallback picks those up via simple-name matching regardless of receiver type — masking this specific defect in the in-process test-pipeline path.

Claude	70e0a7766c	fix(java): address #2561 review — inherited-dispatch test + bodied fail-safe ... Two gitnexus-review-agent findings on PR #2602: - MEDIUM: the bodied-constant MRO-to-host-enum path (a qualified call to an inherited, non-overridden enum method) was claimed in a comment but never tested. Add EnumConst.A.log() -> EnumConst.log#0, exercising E$N's @reference.inherits MRO arm end to end. - LOW: `bodiedName ?? hostEnum` conflated "body-less" with "name synthesis failed on a bodied constant" (reachable only on malformed/error-recovery trees), silently binding an overriding constant's receiver to the host enum — a wrong edge instead of no edge. Switch to `isBodied ? bodiedName : hostEnum` so a bodied constant binds ONLY to its E$N class, mirroring the object_creation_expression branch's skip-on-synthesis-failure. Verified output-neutral on the well-formed bench corpus. Rebaseline the java scope-capture fingerprint (a822cef9 -> d04298a9): the bench corpus IS test/fixtures/lang-resolution, so the new dispatchInherited fixture method shifts it (+6 capture groups); the logic change contributes nothing (confirmed by isolating the fixture-only fingerprint). java.test.ts 242 passed; measure.mjs --check PASS (14 languages); tsc/prettier/eslint clean.

Claude	7666a009f0	fix(java): resolve E.CONST.method() enum-constant receiver dispatch (#2561) ... Calling a method on an enum-constant receiver (E.CONST.method()) emitted no CALLS edge. The receiver "E.CONST" is a two-segment compound receiver; resolveCompoundReceiverClass walks each dotted segment via the owning class scope's typeBindings map, but enum constants had no typeBinding, so the constant segment dead-ended and no target was ever resolved. #2555/#2558 gave bodied constants a first-class synthesized E$N class with an MRO that includes the host enum; this is the receiver-side follow-up. synthesizeJavaAnonymousClassDeclarations now emits a class-scope typeBinding for every enum constant's simple name -> its E$N class (bodied) or the host enum itself (body-less), reusing the exact mechanism a field declaration uses. The generic compound-receiver chain walk then resolves E.CONST.method() with no change to any shared scope-resolution code. Bodied dispatch (EnumConst.A.hook() -> EnumConst$1.hook#0) and body-less inherited dispatch (Plain.A.m() -> Plain.m#0) are covered by new tests in the existing java-enum-constant-body fixture; both were verified to fail against the pre-fix tree.

JAVA_QUERIES had no @definition.record capture, unlike its class_declaration/interface_declaration/enum_declaration siblings and unlike CSHARP_QUERIES' own record_declaration pattern. A Java record's container node was never created, so its HAS_METHOD edges were dropped at persistence even though ownership resolution computed a valid ownerId for its methods. Downstream label mapping, the class-extractor config, the dispatch table, and ownership reconciliation already treated 'Record' correctly - this was purely a missing structure-phase capture.	2026-07-21 07:04:07 +00:00

Gergő Magyar	12600000e3	feat(java): model enum constant bodies as first-class instances; JLS 13.1 anonymous naming (#2558) ... * feat(java): JLS 13.1 immediate-host naming for anonymous bodies + v9 schema window (#2555, step 1) `synthesizeJavaAnonymousClassName` generalizes to both anonymous-body shapes (`object_creation_expression` with a `class_body`; `enum_constant` with a `body:` field) and switches from topmost-host naming to JLS 13.1 binary names: the `$`-joined chain of enclosing host types (`EnumWrap$Mode$1`), numbered per IMMEDIATE host in source order across both shapes (javac's shared counter). Every existing fixture's immediate host is its top-level type, so existing names are unchanged — proven by the 11 #2550 tests passing untouched, not assumed. The owner walk's anonymous branch also fires on `enum_constant` now (the synthesis returns undefined for body-less constants, so the walk continues to `enum_declaration` as before). Identity window: INCREMENTAL_SCHEMA_VERSION 8→9, parse-cache SCHEMA_BUMP 18→19, U-C5 pin extended with the v8-stamp rejection (enum-constant methods re-key `E.hook`→`E$1.hook`; nested-host anons re-key `EnumWrap$1`→`EnumWrap$Mode$1`). Enum-constant Class-node emission and scope-side ownership land in the next commits per docs/plans/2026-07-18-gitnexus-plan-enum-constant-bodies.md (plan is local — docs/ gitignored). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(java): model enum constant bodies as first-class instances (#2555, steps 2-4) `enum E { A { void hook(){} } }` — javac's other anonymous-class shape — joins the #2550 instance model: - Structure: `(enum_constant body: (class_body)) @definition.class` in JAVA_QUERIES; `enum_constant` in javaClassConfig.typeDeclarationNodes with extractName synthesis. The shouldSkipClassCapture guard now also covers enum_constant — without it, extract()'s name fallback would fabricate a Class node from the constant's own identifier (`A`). - Scope: `(enum_constant body: (class_body) @scope.class)` + synthesized `@declaration.class`/`@declaration.name` anchored on the body, so the constant's methods are owned (`ownerId`) and re-keyed (`Method:...:EnumConst$1.hook#0`). - Inheritance: a body-anchored `@reference.inherits` naming the HOST ENUM (javac semantics: E$N extends E) — `mroFor(E$N) ∋ E`, so bare calls from the body to enum helpers pass the ownership gate's MRO arm while the same-file bare-call leak for constant-body method names is closed (discrimination evidence: the #2549 review's archived S1b probe showed the identical shape resolving `local-call` pre-fix). - Nested-host JLS naming verified end-to-end: `EnumWrap$Mode$1` (not `EnumWrap$1`). - Bench: java scope-capture fingerprint rebaselined (new captures + two fixtures), `measure.mjs --check` PASS across all 14 languages. Verified: full java.test.ts 230/230 twice sequentially; TS 254 + JS/ Kotlin 289 (shared-file spot set); schema/scope/owner unit suites 90. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(java): exempt $-chain anonymous class defs from nested-class qualification (#2555 review) Review lens probe caught a HIGH collapse: same-named methods across sibling enum constant bodies attributed to the FIRST body's Method node (`M3$1.hook -> M3.log` where the log() call lives in C's body; the same-target sibling edge vanished entirely under dedup). Root cause: `populateClassOwnedMembers`'s qualifier chains a constant-body class def to `M3.M3$2` — its Class scope's parent is the enum's Class scope, unlike OCE anons whose parent is a Function scope — and its methods to `M3.M3$2.hook`. The structure-phase node id encodes `M3$2.hook`, so the graph-bridge's qualified key misses and falls to the file-wide simple-name lookup: first-write-wins. Fix: `qualify()` now skips CLASS-LIKE defs whose name already carries a `$` chain — a synthesized anonymous binary name is complete by construction (JLS 13.1). Narrowly scoped: `$`-named MEMBERS (legal and real in JS/TS) still qualify against their class, and named nested classes (`Outer.Inner`, #1978) are untouched. Discriminating regression test: same-name/distinct-target sibling bodies must each own their edge, and the misattributed cross-edge must not exist. Verified: full java.test.ts 231/231; Python+Kotlin 459 (heaviest populateClassOwnedMembers consumers) — zero assertion failures. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * chore(ci): prettier formatting + java bench rebaseline at the final corpus (#2555) Two CI reds from the review-fix commit landing AFTER the bench rebaseline: (1) prettier reformat of the new java.test.ts describe; (2) the java scope-capture fingerprint drifted again because the review fix added the java-enum-constant-same-name fixture to the corpus — rebaselined at the true final corpus (196 fixtures, ce104a76…, scaling 1.05 < 1.5), local `measure.mjs --check` PASS across all 14 languages. Lesson honored going forward: the bench rebaseline is the LAST artifact step — any post-review fixture addition reopens it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(java): strict JLS 13.1 chaining through anonymous enclosing types (#2555) Per review discussion: anonymous enclosing types now chain into the binary name instead of flattening to the nearest NAMED host — the immediately enclosing type per JLS 13.1 may itself be anonymous: - anon inside an anon: NestHost$1$1 (was NestHost$2) - anon inside an enum constant: N$1$1 (was N$2) - named nested hosts (unchanged): EnumWrap$Mode$1 `nearestJavaAnonHost` becomes `nearestJavaEnclosingType` (named hosts OR anonymous bodies); an anonymous enclosing type's prefix is its own synthesized name (memo-bounded recursion); numbering is per immediately enclosing type in source order. Top-level-hosted names are untouched — the full existing suite passes unchanged. New coverage: anon-in-anon chain, anon-in-constant-body chain (with ownership), and a bodied constant in a NESTED enum (EnumWrap2$Mode$1 — the one host combination previously untested). Rides the unreleased v9 identity window (doc wording tightened); java bench fingerprint rebaselined at the final corpus, `--check` PASS across 14 languages; prettier clean. Verified: full java.test.ts 234/234 (one worker-crash flake rerun green in isolation).

Gergő Magyar	1abcac9c16	fix(scope-resolution): stop platform builtins resolving to unrelated same-file symbols (#2549) ... * fix(scope-resolution): stop platform builtins resolving to unrelated same-file symbols (#2545) An unqualified call to a platform/language builtin (e.g. TypeScript's global fetch()) could resolve to an unrelated same-file declaration sharing that name, most visibly a Cloudflare Worker's `export default { async fetch(req) {...} }` handler. Two contributing gaps, both fixed: - Object literals had no scope boundary in the TS/JS grammar queries, so a method's/property-arrow's name auto-hoisted past the literal into whatever lexically enclosed it (scope-extractor.ts's auto-hoist logic had nowhere to stop). Give object literals a Block scope, like 6 other languages already do for lexical blocks. - Independently, finalize's per-file bindings bucket (materializeBindings in gitnexus-shared) flattens every local declaration in a file onto its module scope for cross-file import resolution, regardless of true nesting -- so free-call-fallback's scope-chain walk could still hit the leaked binding at module scope. Guard free-call resolution: when a match for a known builtin name (LanguageProvider.isBuiltInName, already populated for TS/JS but never consulted by this pass) has no binding reachable via the true lexical scope chain, leave the call unresolved instead of emitting a false CALLS edge. Verified against the full TS/JS resolver suites plus every other language populating builtInNames (Python, Go, C/C++, C#, Dart, Kotlin, PHP, Ruby, Rust, Swift, Vue) -- 2333 tests, no regressions. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(scope-resolution): extend the #2545 scope-leak fix to Kotlin and Java Anonymous object-expressions (Kotlin `object { ... }`) and anonymous class bodies (Java `new Runnable() { ... }`) have the same missing scope-boundary gap that caused #2545 in TypeScript/JavaScript: a method declared inside has no scope of its own to stop the auto-hoist at, so its name leaks past the container into the enclosing scope. - Kotlin: `(object_literal) @scope.class` (distinct from the already- scoped named `object_declaration`/`companion_object`). Kotlin already populates `builtInNames`, so free-call-fallback's isBuiltInName guard (added for #2545) fully closes the equivalent leak here too -- verified with a `println`-shadowing regression test. - Java: `(object_creation_expression (class_body) @scope.class)`, matching PHP's existing `anonymous_class` handling. Java has no `builtInNames` list, so the isBuiltInName guard doesn't engage -- the scope-tree fix is still correct and necessary (the anonymous class's own methods are now owned by the right scope), but an unqualified call to an unrelated same-file method sharing the anonymous class's method name can still resolve via finalize's per-file module-scope bucket (materializeBindings, shared/ language-agnostic, intentionally not touched by this PR). Documented in the test as a known residual gap, same as TS/JS/Kotlin's own non-builtin-name collisions. Audited every other language for the same shape (a value/container node with no @scope.* capture hosting a would-be-auto-hoisted named declaration): PHP and Vue already handle it correctly (PHP scopes anonymous_class; Vue's <script> delegates to the now-fixed TS/JS query). Ruby, Python, Dart, C#, Swift, Go, Rust, and C/C++ have no query pattern that treats a literal/container value position as a named declaration in the first place, so the bug shape can't occur there. Verified: full Kotlin + Java resolver suites, 468 tests, no regressions. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(scope-resolution): dedicated Object scope kind for object literals (#2545, #2551) Review of the #2545 fix surfaced two defects, both fixed here: 1. The isBuiltInName guard suppressed genuine cross-file imports whose name matches a builtin (`import { fetch } from './fetch-polyfill'` silently stopped resolving -- verified regression vs. main). The leak the guard targets is inherently same-file (finalize's flat bucket is per-file), so the guard now also requires `fnDef.filePath === parsed.filePath`. New regression test covers the polyfill-import shape. 2. The sibling-property case of the reported bug was still broken and masked by a tautological assertion (`c.reason` -- a property that doesn't exist; the real path is `c.rel.reason` -- so the test passed regardless of behavior). In `export default { fetch() {...}, handler: () => fetch(...) }`, `handler`'s bare `fetch()` still resolved to its sibling. Reusing the `Block` scope kind was the root cause: correct for a real lexical block (a nested closure legitimately sees a sibling `let`/`const` from an enclosing `if`/`for`), wrong for object literals, whose members are reachable only via property access -- never as bare identifiers, not even by sibling property bodies. Fix: a dedicated `Object` ScopeKind (gitnexus-shared) -- a hoist boundary whose own bindings scope-chain walkers never consult while still traversing past it to the parent. TS/JS object literals now emit `@scope.object`; the four chain walkers in scope-resolution/scope/walkers.ts (walkScopeChain, findAllCallableBindingsInScope, findCallableBindingsAndAdlBlocker, findExportedDefByName) and free-call-fallback's hasGenuineLexicalBinding skip Object scopes' bindings. Kotlin's anonymous `object {}` keeps `@scope.class` -- unlike JS object literals it has real implicit-this sibling dispatch. Verified with the full resolver matrix run sequentially (TS 254, JS/ Kotlin/Java/Python/Go + TS variants 960, C/C++/C#/Dart/PHP/Ruby 1049, Rust/Swift/Vue/Cobol + route/flow/unit suites 828, scope-extractor/ scope-tree units 51). Worker-pool crashes under parallel suite load reproduced on unrelated files and pass in isolation (known flake, not caused by this change). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * chore(autofix): apply prettier + eslint fixes via /autofix command * feat(java): model anonymous class bodies as first-class Class nodes (#2550, step 1) `new Runnable() { public void run() {} }` now emits a synthesized javac-style `Class` node (`Worker$1`, `$N` = source order within the top-level class) and owns its methods: the enclosing-owner walk attributes `run` to `Worker$1` (re-keyed `Method:...:Worker$1.run#0`, HAS_METHOD from the anonymous class) instead of the lexically enclosing named class. - `synthesizeJavaAnonymousClassName` (ast-helpers): single naming authority for every layer that keys the anonymous class; returns undefined for `object_creation_expression` without a `class_body` child, which also keeps it a no-op for C#'s same-named node type. - `findEnclosingClassInfo`: anonymous-body branch before the generic container walk. - JAVA_QUERIES: `(object_creation_expression (class_body)) @definition.class` (no @name); `getLabelFromCaptures` now lets a nameless `definition.class` through — the parse-worker's existing `!nameNode && !extractedClassSymbol` gate still drops any nameless class the extractor cannot name, so other languages are unaffected. - `javaClassConfig.extractName` synthesizes the name on the extractor path (worker node emission). - Node identities move on unchanged files: INCREMENTAL_SCHEMA_VERSION 7→8 and parse-cache SCHEMA_BUMP 17→18 (the v5 Route-identity precedent) force full re-analyze / cache invalidation. Verified: new #2550 identity tests + resolve-enclosing-owner and has-method suites (53 tests) green. Prep for step 2/3 (scope-side ownership + receiver typeBinding) and the free-call instance-ownership gate per docs/plans/2026-07-18-gitnexus-plan-java-instance-scoped-freecalls.md (plan file is local — docs/ is gitignored by repo policy). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(java): instance-scoped free-call resolution for anonymous-class methods (#2550, steps 2-4) Completes the #2550 instance model on top of the Worker$N identity commit: - Scope-side ownership (java/captures.ts): synthesize `@declaration.class` + `@declaration.name` (`Worker$N`) anchored on the anonymous `class_body` — same range as its `@scope.class`, so the def lands in that Class scope's ownedDefs, `populateClassOwnedMembers` stamps `ownerId` on the anonymous class's methods, and the name auto-hoists exactly like a named class declaration. - Receiver typeBinding (java/captures.ts + type-extractors/jvm.ts): `Runnable handler = new Runnable() { ... }` binds `handler` to the ANONYMOUS class (`Worker$1`), not the declared JDK interface — in both the scope-side TypeRef channel (receiver-bound Case 4) and the worker typeEnv. `handler.run()` now resolves through the receiver path (reason 'global', target `Worker$1.run#0`) instead of depending on the free-call finalize-bucket leak — which is why the prior gate attempt broke it (the #2550 landmine, now explained and structurally removed). - Instance-ownership gate (free-call-fallback.ts + contract + run.ts + java opt-in): with `ScopeResolver.freeCallsRequireInstanceOwnership`, a free call may resolve to a `Method` only when the caller's enclosing class chain (self + MRO via `scopes.methodDispatch.mroFor`) contains the method's owner. Same-file matches only — the `materializeBindings` leak is per-file; cross-file Method matches come through genuine import channels (suppressing them broke the arity-narrowing parity suite, verified). Suppressions recorded as `'free-call-instance-ownership'` outcomes. Java opts in; every other language is byte-identical (flag off). Result on the #2545 fixture: `process()`'s bare `run()` emits NO edge to the unrelated anonymous method (the #2550 bug, closed), while `handler.run()`, same-class implicit-this dispatch, and bare inherited calls (MRO arm) all keep resolving. Verified: full java.test.ts 223/223 twice sequentially (landmine gate); cross-language matrix (TS/JS/Kotlin/Python/Go/C/C++/C#/Dart/PHP/Ruby/ Rust/Swift/Vue/Cobol + callable-value-flow + java-class-impact + core units) — zero assertion failures; worker-crash flakes re-verified green in single-file isolation. Known deferral (documented): EXTENDS/IMPLEMENTS edges from the anonymous class to its constructed type are not yet emitted, so a same-file inherited-but-not-overridden member called ON the anonymous instance does not resolve through the anon MRO; tracked as the follow-up in #2550. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * chore(autofix): apply prettier + eslint fixes via /autofix command * fix(java): anonymous-class inheritance, host coverage, and phantom-node guard (#2550 review) Self-review of the instance model (gitnexus-review with empirical lens probes) surfaced three defects, all fixed: 1. HIGH — the ownership gate suppressed TRUE bare calls to inherited methods inside an anonymous body extending a same-file class (`new Base() { void extra() { work(); } }` lost `extra -> work`): the anon class had no inheritance edge, so `mroFor(Worker$N)` was empty and the MRO arm could never pass. The synthesis now emits an `@reference.inherits` for the constructed type, anchored on the `class_body` so the reference's enclosing class resolves to the SYNTHESIZED def (anchoring on the type node would sit outside the anonymous scope and attribute the edge to the wrong class). Anon classes now get real EXTENDS/IMPLEMENTS edges and inherited bare calls pass the gate. 2. MEDIUM — hostless anonymous bodies materialized a phantom Class node named after the CONSTRUCTED type (`Class:...:Runnable`) via extract()'s extractTypeNameFromNode fallback. New `shouldSkipClassCapture` in javaClassConfig drops the capture when no name can be synthesized. 3. MEDIUM — enum/interface/record-hosted anonymous bodies silently fell back to the pre-#2550 model (mis-attribution + open leak). The topmost-host walk now accepts all four host type declarations (JAVA_ANON_HOST_TYPES), so `EnumHost$1` etc. are modeled; the phantom-node shape disappears for those hosts as a side effect. Also: per-parse-tree WeakMap memo for the `$N` numbering — the helper is called from four independent layers per anonymous body and each call re-scanned the host subtree (`descendantsOfType`), quadratic on anon-heavy files (old-style listener-per-widget Java); and the scope-capture bench fingerprints rebaselined for java/typescript/ javascript/kotlin (`measure.mjs --check` now passes all 14 languages — it failed for every scope query this PR touched; drift notes added per the file's convention). Verified: full java.test.ts 225/225; all 11 #2550 tests including the new anon-extends-base and enum-host scenarios; bench --check PASS. Known remaining (documented, unchanged-old behavior): enum CONSTANT bodies (`A { ... }`) stay unmodeled; nested-host naming is top-level- anchored (`EnumWrap$1`, not javac's `EnumWrap$Mode$1`). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * chore(autofix): apply prettier + eslint fixes via /autofix command * test(storage): update the INCREMENTAL_SCHEMA_VERSION pin to v8 (#2550) The U-C5 reuse-gate test deliberately pins the exact schema version so a bump cannot land without consciously extending the gate expectations. Extend for v8 (Java anonymous-class node identities, #2550): a v7 stamp now fails the strict-equality reuse gate — a pre-v8 index would strand old `Worker.run`-keyed Method nodes alongside the re-keyed `Worker$N.run` ones on unchanged files — and v8 passes. Caught by CI (tests/ubuntu coverage shard 2/3 on PR #2549); the local matrix had not included this unit file. All 7 schema-referencing unit suites verified green (109 tests).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(scope-resolution): model provider-hook value references (#2437) Functions referenced as object-literal property values (provider hooks like emitScopeCaptures: emitCppScopeCaptures) previously produced no edge at all, so impact/context reported a false-safe 0 upstream dependents. Two coordinated halves, per prior art (Kythe ref vs ref/call, Joern METHOD_REF, Feldthaus ICSE'13 field-based call graphs, CodeQL impliedReceiverStep): - Registration -> USES: new ReferenceKind 'value-ref'; TS/JS queries capture pair values and shorthand properties (with @reference.property-key); emitted as a reference-class USES edge, reason 'scope-resolution: value-ref'. Resolution is callable-gated so plain values emit nothing. - Dispatch -> CALLS: new shared pass emitPropertyDispatchCalls synthesizes CALLS (reason 'property-dispatch', confidence 0.7, per-key fan-out cap 32 calibrated on this repo's 16-provider hook tables) from member-call sites to every function registered under the same property key. Deviation from plan: the pass owns value-ref resolution entirely via the post-finalize findCallableBindingInScope walker — the shared registries only see pre-finalize local bindings, so imported hooks (the c-cpp.ts case) were unresolvable through lookupForSite; Reference.propertyKey passthrough dropped as unnecessary. SCHEMA_BUMP 13 -> 14: ParsedFile gains value-ref sites + propertyKey. Verified end-to-end: impact(emitCppScopeCaptures, upstream) now reports 8 impacted / HIGH with extractParsedFile (true dispatch caller) at d=1 via property-dispatch and the c-cpp.ts registration via USES.

Force the one-time full re-analyze (review finding 1, #2522). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(storage): sanitize callable-flow sites per-site at load, log drops The load-time validator rejected the WHOLE ParsedFile when one site was malformed or over-bound, with no logging — and C++ legitimately emits empty-string parameterTypes entries ('' = unknown, the ReferenceSite.argumentTypes convention) for cv-only/ERROR-recovered types, so real repos fell into a permanent, silent warm-cache-miss reparse loop through the #1983-sensitive main-thread path (review finding 7, #2522). Now: '' entries are valid in type arrays; a malformed/over-bound site drops only itself (counted, warned once per load); only non-array garbage — evidence the serialization itself is untrustworthy — rejects the file. Deviation from plan §6 wording: validator-side tolerance replaces emit-side clamps — smaller diff, same asymmetry closed at the single chokepoint. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(scope-resolution): keep declarations in the union for reassigned callable cells The binding-lookup suppression for fact-constrained cells was wholesale: reassigning a declared function through its own name (greet = other; greet()) deferred the call to the solver, which then refused the lexical lookup that resolves the declaration — an unresolvable RHS yielded zero CALLS for a call that resolved pre-flow (review finding 8, #2522). Suppression now applies only to cells bound by FORMAL facts — its actual purpose (a parameter whose grammar emits no declaration binding must not adopt a same-named outer function). Copy/alias/store/load destinations keep their declaration as an inclusion seed (Andersen-style union). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(scope-resolution): count forfeited deferred sites in the budget-bailout warning On work-budget exhaustion the deferred invoke sites end the run with zero CALLS — free-call fallback and reference emission already skipped them — but the warning said 'ordinary graph emission remains untouched', which is false for exactly those sites. The warning context now carries the unresolved deferred-site count and the comment states the real cost (review finding: budget-bailout honesty, #2522). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(scope-resolution): surface dropped property-dispatch keys in stats and warn payload The over-cap warning carried only a count; the dropped key NAMES were discarded and RunScopeResolutionStats had no field, so the PR-body claim 'includes them in resolver statistics' was unimplemented (review finding, #2522; reviewer ask on the fan-out cap). The warn payload now names up to 20 dropped keys and the stats carry propertyDispatchSkippedKeys. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(scope-resolution): drop producer-less ownerQualifiedName from formal sites No capture emitter anywhere produces @callable-flow.owner-qualified-name — the solver branch consuming it was unreachable in production, yet the field was typed, parsed, validated, and unit-tested with hand-built input (review finding 16, #2522; YAGNI). Re-add with a real producer if C++ qualified member declarators ever need it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(scope-resolution): drop dead callable-flow knobs CallableFlowPassingMode 'callable-object' had no producer and no consumer distinguishing it, and CallableFlowCaptureOptions.extractCallArguments had no language providing it (unlike its live sibling extractCallCallee) — review finding 17, #2522 (YAGNI). The invocation-kind 'callable-object' is a different, live concept and stays. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ingestion): bind subscripted callable cells to the container, not the index terminalIdentifier iterates children in reverse, so tbl[i] = handler seeded the INDEX variable's cell (polluting a same-named formal) and tbl[i](7) looked up the callee under i in a different scope — no join, no CALLS edge for the classic function-pointer-array dispatch (review finding 12, #2522). Subscript nodes now recurse into their container field only, in both bindingIdentifier and terminalIdentifier, across the fielded grammars (C/C++/JS/TS/Python/Go/Java). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ingestion): make cross-function file-scope callable bindings resolvable Two stacked gaps killed the canonical C callback-registration pattern (fp assigned in init(), called in run()) — the exact #2437 false-safe this PR exists to fix (review finding H1, #2522): 1. isVisibleValueBinding only consulted assignment regions and formals, so a call in a function OTHER than the assigning one emitted no invoke fact. A declared callable-typed binding is now a value binding wherever its declaration is visible (visibleCallableSignature). 2. The C scope query had no @declaration.variable pattern for function- pointer declarators — void (*fp)(int); created no scope-tree binding, so the seed (init) and invoke (run) cells canonicalized to different keys and never joined. Both bare and initialized forms now bind. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(c): detect variadic parameters via the named variadic_parameter node tree-sitter-c materializes '...' as a named variadic_parameter node; the anonymous-token checks never matched, so variadic function-pointer signatures were emitted with a wrong fixed arity and no '...' sentinel (review finding, #2522). C++ is unaffected ('...' stays an anonymous token there); the token checks remain for such grammars. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ingestion): emit invoke facts for field-stored callable member calls The C ops-vtable pattern (o->run = handler; o->run(1)) captured the store but never the call — the member path in emitCallFacts bailed for languages without protocol methods, and the value-binding index recorded the member store under the OBJECT's name ('o'), not the member's ('run') (review finding 11/M3, #2522). Member destinations now also record their terminal member name, and a member call whose name-cell has a visible store emits an indirect invoke — gated on the store so plain accessor calls (map.get) stay inert. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cpp): disambiguate (obj->*ptr)() ERROR recovery by token order tree-sitter-cpp groups the recovered '->*' two ways depending on error-recovery cost (identifier lengths): [identifier, ERROR '->*m'] or [ERROR 'obj->*', identifier]. The recovery assumed the first shape, so the second silently swapped receiver/member and dropped the call site — the committed test passed only by name luck (review finding H2, #2522). The identifier's position relative to '->*' inside the ERROR now decides roles. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cpp): class members are never file-local in hasFileLocalCallableLinkage The name-keyed file-local set is populated from every static declaration, so an in-class 'static void make();' (external linkage — in-class static means no-instance) and any member sharing a name with a static free function were over-marked, refusing legitimate cross-file declaration/definition joins (review finding 13/M2, #2522). Method and Constructor defs now bypass the name-set, per the hook's own linkage-only contract. Deviation from plan step 13: the regression is a unit-level contract pin rather than an end-to-end join test — C++ merges out-of-line member definitions onto the member node by qualified identity, so the graph shape cannot discriminate the join refusal for members. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cpp): classify parameter passing mode from the declarator chain only A whole-subtree scan for reference_declarator inverted copy vs alias: void reg(void (*cb)(int& out)) marked the by-value pointer cb as 'reference' because of the NESTED parameter's int&, making the solver back-propagate formal targets into every caller's argument cell — alias semantics for a copy (review finding 14/M5, #2522). The chain walk never descends into nested parameter lists; a reference anywhere ON the chain (int& x, void (*&cb)(int)) still aliases. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ruby): bare identifiers are calls, not callable references Ruby parses a receiver-less zero-arg method call identically to a variable read, so 'action = process' — which CALLS process and stores its return — seeded action with the callable and minted a wrong CALLS edge from any dispatch through it, confirmed end-to-end (review finding 15/HIGH, #2522). New provider knob bareNamesAreCalls: a bare name that is not a provably local value binding and not an explicit reference form (method(:x), lambda/proc) emits no flow fact, on both the assignment and argument paths. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(go): pair multi-value := positionally instead of cross-wiring The shared field fallback took the FIRST LHS identifier and the LAST RHS identifier of Go's expression_list pair, cross-wiring 'a, b := f, g' and synthesizing a garbage comma-joined qualified name — the real relationships were silently dropped (review finding 16, #2522). extractAssignment may now return multiple pairs; Go pairs list entries positionally and emits nothing for a length mismatch (multi-return call RHS). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(java): drop get/test from callableProtocolMethods 'get' and 'test' collide with ubiquitous non-functional-interface APIs (Map/List/Optional/Future.get), so every ordinary container access emitted a spurious callable-object invoke fact — high-volume misleading graph facts with a cross-wiring risk on receiver-name reuse (review finding 17, #2522). Supplier.get/Predicate.test dispatch is deliberately traded away until the check can gate on the receiver's declared type. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(rust): pin the qualified-name no-degrade guard as a hard invariant Rust's scoped_identifier callable-reference capture over-includes unit enum variants and associated constants (Shape::Square seeds as if callable); they stay edge-free only because resolveSeedCandidates refuses to degrade an unresolved qualified name to a simple-name lookup (review finding 18, #2522). Capture-side type filtering would false-negative on tuple-variant constructors, so the guard IS the contract: documented as a hard invariant (Go's mis-shaped multi-value forms also rely on it) and pinned end-to-end. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(php): remove nonexistent optional_parameter node type tree-sitter-php has no 'optional_parameter' — defaults ride on simple_parameter — so the entry was dead weight the #1920 literal gate does not cover for capture-option Sets (review finding 19, #2522). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cobol): detect procedure pointers on fixed-format sources Two stacked defects made the feature a no-op on classic sequence-numbered fixed format (review finding 20/H3, #2522): 1. parseDataItemClauses' USAGE alternation knew POINTER but not PROCEDURE-POINTER/FUNCTION-POINTER, so the dataItems filter was dead. 2. The raw-line fallback scanned UNCLEANED text, where the sequence number satisfied the leading digits and the LEVEL NUMBER got captured as the pointer name. It now scans preprocessed lines and requires a letter- initial name (COBOL data names must contain a letter). 161 COBOL preprocessor/copy-expander tests stay green; free-format matrix case unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cobol): skip comment lines in SET seed/copy scans A commented-out SET (indicator-column '*'/'/' or free-format '*>') produced a live seed and a false CALLS edge from dead code (review finding 21/M1, #2522). The scan now skips indicator-column comment lines and strips inline '*>' tails before matching. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(architecture): document callable-flow-only mode and skipped-key reporting The Callable-value flow section omitted scopeResolutionEdgeMode: 'callable-flow-only' — a real emit-pipeline branch that suppresses all ordinary emission for standalone providers (review finding 22, #2522) — and predated the skipped-key names/stats surfacing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(scope-resolution): correct value-ref resolution attribution and stale pdg-gating comments The value-ref contract comment claimed MethodRegistry resolution — the mechanism is the post-finalize findCallableBindingInScope walker owned by emitPropertyDispatchCalls (resolveReferenceSites skips these sites). Three 'only under --pdg' calleeIdSink comments were falsified by the #2437 gating change (callee-id-sink.ts's header was updated; these copies were missed). Review finding 23, #2522. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(ingestion): direct unit coverage for synthesizeCallableFlowCaptures The 1,100-line shared synthesizer had no test naming it — only downstream consumers were covered (review finding 24, #2522). Pins seed/invoke/ formal/argument emission, subscript container binding, store-gated member invokes, produced-value guards, and the bareNamesAreCalls knob over a minimal options object so assertions target the synthesizer's own semantics. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(resolvers): deepen shallow-language coverage; fix Kotlin/Swift reassignment gaps it exposed Adds the COBOL SET x TO y copy-branch scenario and conditional-assignment scenarios for Kotlin, C#, Swift, and Dart (10 languages previously had one generic case each — review finding 25, #2522). The new scenarios exposed two real capture gaps, fixed here: - tree-sitter-kotlin's 'assignment' node is fieldless, so nested reassignments (chosen = ::target inside a block) produced no flow facts; Kotlin's extractAssignment now decomposes it positionally. - tree-sitter-swift fields its assignment as target:/result:, neither in the shared fallback's field lists; both added. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(infra): literal-validation gate for callable-capture option Sets The #1920 gate validates query literals and exported configs but not the module-private *_CALLABLE_CAPTURE_OPTIONS Sets consumed by the shared synthesizer — a typo'd node type silently captures nothing (PHP shipped a dead 'optional_parameter'; review finding 26, #2522). Every <key>NodeTypes Set literal is now validated against its language's grammar; name-carrying sets (callableProtocolMethods, memberPointerOperators) are deliberately outside the contract. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(storage): centralize corrupt-fixture casts into makeStoreEntry The callable-flow store tests scattered 'as unknown as' double-casts per fixture (review finding 27, #2522; standing no-as-any rule). One typed helper now owns the single controlled escape hatch for building malformed serialization-boundary payloads. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * chore(bench): refresh capture fingerprints after review fixes python-scope: the committed baseline (8d5c3699) never matched this branch's code — CI's benchmarks arm was red on the PR head (review finding 2/HIGH, #2522); regenerated (a99e69ab), scaling 1.04 in budget. scope-capture: ruby/cpp/swift/java/kotlin drifted from the review-fix commits (bare-name suppression, passing modes + ->* recovery, assignment fields, protocol narrowing, positional assignment); all 14 languages re-verified PASS with ratios <= 1.18 against the 1.5 budget. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * chore(docs): untrack docs/plans working documents docs/ is gitignored (local working docs); the plan files were force-added past the ignore. Untracked from the index only — they stay on disk. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(golden): regenerate captures goldens after callable-flow review fixes The per-language digest guards (csharp/go/php/python/ruby/rust/swift) locked the pre-fix capture output; the review-fix series intentionally changed it — store-gated member invokes, subscript container binding, Ruby bare-name suppression, Swift assignment fields, positional pairing. Regenerated with UPDATE_GOLDEN=1; clean verification run 59/59; all other parity/golden guards (pipeline-graph, spring-route, python parity) pass untouched at 33/33. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ingestion): prototypes are callees, not callable value cells The cross-function visibility fix indexed EVERY signature-bearing declaration as a value binding — including plain function/method prototypes (void f(int);). Every call to a declared function then became an indirect invoke, and with emitCanonicalInvokeReference (C/C++) minted a free-call reference that resolved through the registry, bypassing the precise passes' two-phase/ambiguity/subobject suppression — eight phantom CALLS edges in the cpp resolver suite on CI. Only declarations whose binding identifier sits under a pointer/ parenthesized declarator (callable-typed variables like void (*fp)(int);) create value cells now. cpp resolver suite 331/331; callable-value-flow + C/C++ suites 181/181 (the cross-function fp regression still passes); cpp fingerprint rebaselined, both bench gates PASS.

A Spring/Kotlin/C# binding can now reuse the core with its own resolver (proven by constant-resolver.test.ts driving it with a Java-style resolver). * fix(routes): treat the constant-fold cycle guard as a recursion stack (#2391) The `visited` set in `foldName` was added-to but never removed on unwind, so a constant referenced more than once in a single fold — `A + A`, a reused separator (`SLASH + PATH + SLASH`), or a diamond `X = P + Q` where P and Q share a base — tripped the cycle guard on its second occurrence and the whole route was silently dropped by the skip floor. Pop the guard in `finally` so it tracks the ACTIVE resolution stack, not every name ever seen: a true cycle (a name still on the stack) is still caught, but a name that already resolved and popped folds again. Re-computation stays bounded by MAX_RESOLVE_DEPTH, so no blowup is reintroduced. Locked in constant-resolver.test.ts (A+A, reused separator, shared-base diamond); the pre-existing real-cycle and depth-cap cases still return null. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(routes): make module-constant binding writes mutually exclusive (#2391) `extractPythonModuleConstants` kept `literals`, `exprs`, and `imports` as three independent maps: `setName` cleared literals+exprs but never `imports`, and an import never cleared a prior literal/expr. Since `foldName` checks literals > exprs > imports regardless of source order, a name that was both imported and locally (re)assigned kept both bindings and the wrong one won — `from .c import ROUTE; ROUTE = os.getenv(...)` resolved the STALE import instead of dropping, a confidently wrong route path (the exact skip-floor invariant this feature is meant to uphold). Treat the three maps as one logical namespace: any write to one clears the other two for that name (via `imports.delete` in `setName` and a `bindImport` helper), so last-binding-in-source-order wins, matching Python. An import both imported and dynamically rebound now drops. Folding `+=`/`+` onto an imported base remains deferred (it drops safely, never a stale value). Locked in python-const-resolver.test.ts: dynamic-rebind drops, literal-shadows- import, import-shadows-literal, and `+=`-on-import drops. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(routes): widen the group cost-gate to catch literal-leading concats (#2391) `NONLITERAL_ROUTE_DECORATOR_RE` required the first decorator argument to START with an identifier, so a string-literal-leading concat like `@router.get("/api" + SUFFIX)` never tripped `hasComposedRoute`. When such a route was the ONLY composed shape in a repo, the group layer left `constantsByFile` empty and dropped the route, while the ingestion side (which has no gate) resolved `/api/users` and emitted a Route node — an R4 provider/graph parity break. Widen the gate to also fire on a string-literal-leading `+`-concat, detected by a `+` before the closing paren on the decorator line. Gating on the `+` (not merely a leading quote) keeps a plain literal route `@router.get("/x")` OFF the gate, so a literal-only repo still pays no parse pass. Locked in fastapi-composed-provider.test.ts: a sole literal-leading concat now resolves (parseCalls>0 + provider emitted), plus previously-uncovered `@app.<verb>(CONST)` EXPR-branch resolution; the literal-only no-parse gate case still passes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(routes): correct package-init and over-deep relative import resolution (#2391) Two edges in `resolvePythonImport`: - `from . import X` (empty module after the dots) resolved to a sibling `<dir>.py` instead of the package `<dir>/__init__.py`. Resolve the bare-package case to `__init__.py`. - An over-deep relative import (more extra dots than the importing file has directory levels) silently clamped `dirOf('')` to `''` and could match an unrelated root-level `<name>.py` — a wrong file. Guard with `walk > depth → null` so an import that escapes above the repo root drops (skip floor). Both preserve the exact-match / ambiguity→null behavior for ordinary relative and absolute imports. Locked in python-const-resolver.test.ts: `from . import` → `__init__.py` (and null when absent), and an over-deep import returns null even when the clamped target file exists. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(routes): bound parseConstOperands recursion depth (#2391) `parseConstOperands` recursed on `binary_operator` children with no depth bound. A stack overflow is not currently reachable (tree-sitter caps expression nesting below the JS stack limit, so it throws on a deep `+`-chain before this runs), but add a depth guard (cap 64, mirroring the fold engine's MAX_RESOLVE_DEPTH) as defense-in-depth: a pathological chain now floors to null (skip) rather than relying on tree-sitter's limit. The `depth` parameter defaults to 0, so all existing callers are unaffected. Locked in python-const-resolver.test.ts: a 100-term `+` chain yields no binding (null) instead of throwing; ordinary short chains still fold. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * perf(routes): read each .py once in buildPythonRepoContext (#2391) The group repo-context builder read every `.py` file from disk twice: once in the `include_router` cross-file pre-pass and again in the #2391 constant cost-gate loop — an unconditional 2x read on every Python repo, on every group extraction. Hoist a single read pass that populates one `pyContents` map (and computes the composed-route cost gate); both the include_router pre-pass and the constant-map pass now consume the cached content. Behavior-preserving — a literal-only repo still does one read and zero parses. Covered by the existing group unit + integration suites (R4 parity and include_router prefix joins unchanged). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(routes): tidy constant-resolver docs and declaration order (#2391) Three no-behavior nits from the PR #2393 review: - Name `conditional_expression` (`x if c else y`) in the `parseConstOperands` jsdoc list of shapes that deferred to null. - Move `NONLITERAL_ROUTE_DECORATOR_RE` above `buildPythonRepoContext`, which references it — it read as a forward reference before (runtime-safe, but confusing). - Correct the integration-test comment that called `/v2/api/v1/widgets/get` "ingestion-only garnish": the group side emits it too (asserted separately); the four paths in that block are the shared-parity set. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(routes): fold `X += "…"` onto an imported base constant (#2391) Previously `from .c import BASE; BASE += "/v1"` dropped (the extractor could not represent "the imported prior value" as an operand without self-referencing X and tripping the cycle guard). Preserve the imported prior under a synthetic `$imp$N` key — `$` can never appear in a Python identifier, so it cannot collide with a real name — and reference it, so the augmented assignment folds to `<imported BASE>/v1`. Extractor-only: no change to the `Operand` type, the fold core, or the cache shape, so no SCHEMA_BUMP. An imported base that is itself unresolvable still drops (skip floor preserved — never a wrong path). Locked in python-const-resolver.test.ts: single and chained `+=` fold onto an imported base; an unresolvable base still drops. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(routes): resolve bare decorator constants via the by-name entry (#2391) The group `resolveExprArg` hand-built `[{ kind: 'ref', name }]` and called `resolveOperands` for a bare-constant decorator argument — exactly what the language-agnostic core's `resolveConstant(file, name, repo)` seam does. Call it directly for the identifier case. This gives the previously test-only by-name entry point a real production caller (it is the documented reuse seam for future JVM/other bindings), drops the synthetic operand construction, and lets the now- unused `Operand` type import go. Behavior-identical — the `+`-concat path still parses to an operand list and folds via `resolveOperands`. Guarded by the existing group provider suite (bare-constant and concat cases). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * perf(routes): parse each .py once in buildPythonRepoContext (#2391) The repo-context builder ran two parse loops — the include_router prefix pre-pass and the #2391 constant-map pass — so an include_router file in a composed repo was tree-sitter-parsed twice. Merge them into a single pass that parses each `.py` at most once and feeds both extractions from the same tree; a file that needs neither pass is still not parsed at all (cost gates unchanged). Complements the earlier single-read-pass change (this is the single-parse counterpart). Behavior-preserving (prefixes, R4 parity, and cost gates verified by the group + integration suites). Locked with a parseCalls assertion: a file needing both passes is parsed once, not twice. Note: a cross-run (cross-process) constant-map cache — the other deferred perf idea — remains out of scope; it needs disk persistence + invalidation and would add hashing/IO cost on the common path, so it fails the minimal-change bar this single-parse dedup meets. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(routes): bound constant-fold work and output to prevent OOM (#2391) The `finally`-popped cycle guard (recursion-stack semantics) correctly folds diamonds/repeated refs, but popping the guard removed the accidental work cap the old seen-ever set provided: a wide shared-descendant DAG re-folds each child once per reference, and a self-multiplying concat (`X = A + A; A = B + B; …`) builds a genuinely exponential string. Reviewers reproduced ~16.8M folds escalating to `RangeError: Invalid string length` and heap OOM — and neither fold call site is wrapped in try/catch, so it crashed the whole phase rather than dropping the route. Two complementary bounds, both flooring to null (skip), never a wrong value: - a never-popped `memo` in `foldName` caps recomputation at O(nodes) (successes only — a null may be transient on a cyclic branch); - a `MAX_FOLD_LENGTH` (8192) cap in `foldExpr` drops a fold whose output grows past any real route path, bounding the string size the depth cap does not. Corrects the prior "≤ 2^8 folds" comment (output grows multiplicatively, not additively). Locked with a 64^4-fanout construction that now drops in ~ms instead of OOMing; diamonds/cycles/depth-cap behavior unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(routes): snapshot assignment RHS refs at the assignment line (#2391) `ROUTE = BASE` was stored as a lazy `ref(BASE)`, resolved against BASE's FINAL binding. So `ROUTE = BASE; BASE += "/v1"` (or `ROUTE = API; API = "/other"`) resolved ROUTE to the MUTATED value — a confidently wrong path, since Python assigns by value at the `ROUTE =` line. This was latent for local constants at the base of this feature and the `+=`-on-import work extended it to imports. Snapshot each assignment/`+=` RHS reference to a bound name into that name's current frozen value at the assignment line (`freeze`/`snapshot`): a literal value, a copy of the current expr (whose refs are already frozen), or an import preserved under a `$imp$N` alias. Unbound refs (forward references) stay lazy. A later rebind of the aliased name can no longer change the earlier binding. `freeze` also unifies the previous `currentOps` + inline import-alias logic. Locked in python-const-resolver.test.ts: aliased-import-then-`+=`, aliased-local-then-`+=`, aliased-local-then-rebind all resolve to the pre-mutation value; normal reference chains still fold. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(routes): fold group identifier args via resolveOperands for parity (#2391) Resolving a bare-constant decorator arg through `resolveConstant` entered `foldName` at depth 0, whereas the ingestion side folds `routePathOperands` through `resolveOperands([{ref}])`, entering at depth 1. At the MAX_RESOLVE_DEPTH boundary the group tolerated one more hop than ingestion, so a deep alias/re-export chain resolved in the group provider set but dropped from the graph Route nodes — an R4 parity break. Restore the operand-list path in the group so both subsystems share identical fold-entry depth. (`resolveConstant` reverts to the documented agnostic-core seam.) Locked in constant-resolver.test.ts: a 4-hop chain that `resolveOperands([ref])` drops but `resolveConstant` resolves, documenting why the group must use the operand-list entry. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(routes): match multiline literal-leading concats in the cost gate (#2391) `NONLITERAL_ROUTE_DECORATOR_RE` used `[^)\n]*` so it only saw a literal-leading `+`-concat when the `+` was on the same line as the opening quote. A Black-formatted `@router.get(\n "/api"\n + SUFFIX\n)` therefore failed the gate, and when it was the only composed route in a repo the group dropped it while ingestion (which parses the tree, not the raw line) resolved it — an R4 parity break. Drop the `\n` exclusion: `[^)]*` spans the wrapped argument but stays bounded by the decorator's own closing paren, so a plain literal route still never trips the gate. Locked in fastapi-composed-provider.test.ts with a multiline concat fixture. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(routes): bump SCHEMA_BUMP for changed extractor output + E2E snapshot lock (#2391) `extractPythonModuleConstants` now emits DIFFERENT `moduleConstants` for the same source (binding mutual-exclusivity clears stale imports; RHS refs are snapshotted; `$imp$N` aliases). That output is cached verbatim in the parse cache, so a warm shard built at the pre-fix version would replay stale — in one case actively wrong — folded values, and the correctness fixes would silently no-op on upgrade. Bump SCHEMA_BUMP 11→12 to force re-extraction (same warm-cache-replay class the original 10→11 bump addressed for the field addition). Also adds the first end-to-end coverage for the new behavior through the real ingestion pipeline: app/snapshot.py aliases a constant (`SNAP = API_V1`) then mutates the source (`API_V1 += "/mutated"`), and the test asserts the Route node is `/api/v1`, never `/api/v1/mutated` — a case the pure-function unit tests covered but the pipeline did not.
