fix(analyze): replace the hand-incremented schema version with a derived DDL fingerprint (#2798) (#2808)
* feat(schema): derive a fingerprint from the DDL this build creates `SCHEMA_FINGERPRINT` is a sha256 digest of the node and relation DDL that `runSchemaCreationQueries` actually executes, in the same shape as the existing `taintModelVersion` stamp (hex, sliced to 12). It exists because `INCREMENTAL_SCHEMA_VERSION` is hand-picked and has to *predict* whether an on-disk database matches this build's DDL. That number has collided with `main` eight times, twice exactly — and an exact clash is the quiet one, because the reuse gate is a strict `===`. `EMBEDDING_SCHEMA` is deliberately excluded: its `FLOAT[N]` width comes from `GITNEXUS_EMBEDDING_DIMS` at module load, so folding it in would make the digest a function of the environment rather than of code, and two runs of the same build under different env would thrash full rebuilds. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(storage): record the DDL fingerprint in RepoMeta `RepoMeta.schemaFingerprint` stores the digest of the DDL an index's tables were actually created from. It is the derived companion to `schemaVersion`, not its replacement: both are compared, and both must match. Absent means mismatch, deliberately. Grandfathering a missing fingerprint would let an incremental top-up stamp a fresh one onto a database whose DDL was never verified, permanently certifying exactly the wrong-shaped index the field exists to catch. The cost is one full rebuild per pre-existing index. The version ladder gains a note that its "re-check against origin/main before merge" ritual now only guards *semantic* bumps. v25, v26, v30, v31 and v34 all changed emitted ids, edges or wire formats while leaving the DDL byte-identical, and the fingerprint cannot see any of them — but DDL collisions no longer need renumbering. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(analyze): gate index reuse on the DDL fingerprint, not just the version (#2798) `INCREMENTAL_SCHEMA_VERSION` is a hand-incremented integer that has to predict a derived fact: whether the on-disk DDL matches the code's DDL. It has collided with `main` eight times, and twice the collision was *exact*. An exact clash is the silent one. Two builds stamp the same number over different DDL, the `===` reuse gate reads the index as current, every `CREATE ... TABLE` is then skipped as "already exists" (suppressed in `runSchemaCreationQueries`), and the edges whose endpoint pair the live database cannot hold are dropped by `fallbackRelationshipInserts`' bare `catch`. The result is a wrong graph, with no error anywhere. Reuse now requires the version AND the DDL fingerprint to match, in both the pre-pipeline force-rebuild guard and the `isIncremental` predicate, and the fingerprint is stamped alongside the version at the end of a run. Both conditions are necessary. The fingerprint does not replace the integer: most entries in the version ladder change emitted ids, edges or wire formats while the DDL stays byte-identical, and a fingerprint-only gate would stop forcing rebuilds for all of them. What it does buy is that two branches picking the same number no longer need renumbering. The new branch sits above the `alreadyUpToDate` fast path for the same reason the version guard does — a clean tree at an unchanged commit would otherwise early-return before either check ran. Closes #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(analyze): pin the DDL fingerprint gate and its two failure cases `schema-fingerprint.test.ts` pins the properties the gate rests on: the digest covers exactly the node and relation DDL that gets executed (recomputed from the exported lists, so adding a table or a FROM/TO pair without the fingerprint moving is impossible), it excludes the environment-derived embedding DDL, and it moves when any covered string moves. The two `incremental-orchestration` cases exercise the production path rather than modelling it: an index carrying the *current* version with a foreign fingerprint, and one with no fingerprint at all. Both were run against the pre-fix tree first and both failed there with `alreadyUpToDate === true` — the fast path swallowing the mismatch, which is the #2798 symptom exactly. `call-summary-schema-version.test.ts` widens its gate model to two equalities. The second argument defaults to the current fingerprint so all 33 existing version cases read unchanged, and a new case covers the collision, the legacy absence, and the semantic bump the fingerprint cannot see. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(review-skill): point the schema-constant check at the fingerprint, not the deleted integer All four `gitnexus-review` SKILL.md mirrors told reviewers to verify `INCREMENTAL_SCHEMA_VERSION` "was bumped or regenerated". That constant no longer exists, so the instruction sent every future reviewer looking for something they could not find — and, worse, past its replacement. The check for graph DDL is now derived: `SCHEMA_FINGERPRINT` moves on its own, so the question is whether the diff changed a string in `NODE_SCHEMA_QUERIES` / `REL_SCHEMA_QUERIES`, and whether a newly added DDL array was folded into the fingerprint at all — the one way the derived gate can still be bypassed. What did NOT change is called out explicitly: the parse-store `SCHEMA_BUMP` and the bench fingerprint sets are still hand-maintained and still need the re-check-against-base ritual, and semantic changes that leave the DDL untouched fall outside the fingerprint entirely — those rely on the analyzer runner-identity receipt. Found by the review swarm's docs lane. The original plan for #2798 claimed no documentation mentioned the constant; that sweep covered five root docs and never looked at `.claude/skills/**` or the three mirrors. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(migration): record the one-time rebuild the fingerprint switch costs Replacing `schemaVersion` with `schemaFingerprint` means every index written by an earlier GitNexus carries no fingerprint, reads as a mismatch, and is rebuilt once. That is deliberate — grandfathering absence would stamp a fresh fingerprint onto a database whose DDL was never verified — but until now it was undocumented, so a user's first post-upgrade analyze would announce a full re-analyze with nothing to explain it. MIGRATION.md already sets the precedent: PR #2363's meta.json → gitnexus.json rename was equally automatic and equally in need of an entry. This follows that shape, and is explicit about the parts that are easy to undersell: - the cost is per INDEX, and branch-scoped slots (#2106) each pay separately; on a large repository a full re-analyze is substantial, not a blip; - rollback is safe — an older binary sees no `schemaVersion` and forces its own rebuild, which is a cost, never a stale graph; - alternating between an old and a new binary rebuilds on every switch, because the end-of-run meta is written as a fresh literal so neither field survives the other's run. The retired ladder's per-version rationale is pointed at in git history rather than reproduced: `git show 561f913a3:.../repo-manager.ts`. That commit is an ancestor of origin/main, so the pointer survives this branch being squash-merged. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(identity): cover workspace-linked packages in the analyzer dependency digest `dependencyNames` enumerated `dependencies`, `optionalDependencies` and `peerDependencies` only. `gitnexus-shared` is declared as a devDependency (`file:../gitnexus-shared`), and in a source-mode run the build root is the gitnexus package tree, which does not contain that sibling. So a change to gitnexus-shared moved neither `build.digest` nor `dependencyRuntime.digest`. That gap matters more since #2798 deleted `INCREMENTAL_SCHEMA_VERSION`. A DDL-affecting edit there is still caught by `SCHEMA_FINGERPRINT`, but a SEMANTIC-only edit — a new `REL_TYPES` member, say, where the relation table carries a bare `type STRING` column so no CREATE statement moves — was covered by nothing at all. Roughly thirty of the retired ladder's entries were exactly that change class, and the runner-identity receipt is what now carries them. Only checkout-local specifiers are added: `file:`, `link:`, `workspace:`, `portal:` and npm's bare local-path shorthands. Pulling in every devDependency was rejected — vitest, eslint and typescript would enter the digest and force a full re-analyze on unrelated tool bumps, which is worse than the hole. Scanning the linked sibling for the first time exposed a latent throw: `collectArtifacts` honoured `PRUNED_RUNTIME_DIRECTORIES` only for a real directory, so a SYMLINKED `node_modules` fell through to the payload branch and died with "Analyzer identity input is not a file". Worktree-style dev layouts and pnpm shared stores hit this immediately — verified in this worktree, where `gitnexus-shared/node_modules` is such a symlink. Pruning it loses nothing: packages beneath are still reached through `resolveDependencyPackageRoot`. Verified: a real `analyze` in this worktree succeeds with `packageCount` 259; editing the linked package's source moves the digest, bumping an installed registry devDependency does not, and removing the link moves it. `DEPENDENCY_RUNTIME_CANONICALIZATION` is deliberately not bumped — freshness compares digests, not the label, and the input-set change already moves them. Follow-up worth having: no fixture in the suite declares `devDependencies`, so this has no regression test yet. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(analyze)!: delete INCREMENTAL_SCHEMA_VERSION, gate reuse on the DDL fingerprint alone The integer and its ~180-line version ladder are gone, along with `RepoMeta.schemaVersion`. Index reuse is now decided solely by `SCHEMA_FINGERPRINT`; a mismatch — including the absent stamp every pre-existing index carries — warns and forces a full re-analyze, which wipes and recreates the database so the tables are built from the current DDL. Deleting the integer is safe because it was already redundant: the runner-identity guard deep-compares the whole schema-v4 receipt, including a digest over the build tree, and forces a rebuild on ANY analyzer delta. Verified empirically — a comment-only edit to logger.ts, with the fingerprint byte identical, produced "runner identity changed ... forcing a full rebuild". The fingerprint is not thereby redundant. It fires where that guard cannot: a DDL-affecting change in `gitnexus-shared`, which is a workspace-linked devDependency and so sat outside both digests until the companion commit closed that gap. Review findings folded in, each correcting a line this rewrite itself introduced and never published: - B1: two assertions matched a log string the rewrite had renamed; both tests failed. They now assert what production emits. - B2: the pre-existing downgrade test perturbed `schemaVersion: 7`, a field this change deletes, so the spread carried a valid fingerprint, every guard passed, and the run legitimately took the fast path. It perturbs the fingerprint now, restoring the only integration coverage of the gate-above-the-fast-path ordering invariant. - N5: duplicate `schemaFingerprint` keys silently collapsed two assertions into one (TS1117). - N6: the absent-stamp message told non-git repositories their index was "built by an older GitNexus version" — on every run, about an index this exact build had just written. Non-git repos never record a fingerprint, and now the message says so. - N9: the on-disk stamp is shape-checked before being echoed, so a crafted gitnexus.json cannot push ANSI escapes through the CLI log. - N7: a test case that re-computed the same digest expression with its operands swapped, mislabelled as a randomness check on a module-level const. - N10: comments claiming the digest "cannot collide" (it is 48 bits), pointing at a vector-column gate that does not exist, and asserting storage/ is free of a core/ dependency two lines below a core/ value import. None of these were caught by `tsc -p tsconfig.json`, which covers src only, nor by eslint, where no-dupe-keys is off. `tsconfig.test.json` reports all three test defects and is not currently wired into CI. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(schema): pin that the fingerprint covers every DDL statement init executes `SCHEMA_QUERIES` is the list `runSchemaCreationQueries` iterates — the DDL that actually runs. The fingerprint hashes only two of its three members, and until now no test imported `SCHEMA_QUERIES` at all, so nothing tied the two together. A fourth member appended to that array — the one literally named for what init executes — would have been invisible to the gate. Every existing test would still pass, because they all recompute the digest from the same two arrays the fingerprint already uses. An index whose gate passed would then run `initLbug` over the old database, where `runSchemaCreationQueries` suppresses "already exists", so the new table would never be created and its edges would be dropped by `fallbackRelationshipInserts`' bare catch. A wrong graph, no error — exactly the failure #2798 exists to end. The check is a pure predicate over (executed, fingerprinted, documented exclusions) rather than a positional `toEqual`, so `EMBEDDING_SCHEMA` is named as an exclusion with its reason — its FLOAT[N] width is environment-derived — rather than sitting in a list where a future reader might "fix" it by folding it in. It asserts both directions and is order-insensitive, leaving ordering to the digest assertion that already pins it. The negative case is pinned in CI rather than checked by hand once: the same predicate over a synthetic fourth member must report it. If a refactor ever makes the predicate vacuous, that case fails even though the positive one would not. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(analyze): name the invariant the version deletion now rests on Deleting `INCREMENTAL_SCHEMA_VERSION` moved a load-bearing guarantee into an implicit one. Roughly thirty of the retired ladder's entries changed no DDL at all — node ids, wire formats, resolution tiers — and the fingerprint is structurally incapable of firing on any of them. Their only remaining cover is the analyzer runner-identity receipt, and nothing in the suite said so. This adds a table over the real `analyzerRunnerIdentitiesEqual` with a well-formed schema-v4 receipt: byte-identical reuses; an entrypoint-only difference reuses (CLI vs analyze worker); a moved build digest with unchanged DDL forces — that case IS the invariant, commented as such; and a dependency change, an ABI change, undefined, null, a schema-v3 legacy receipt, a missing build section and a non-sha256 digest all fail closed. The deleted `expect(INCREMENTAL_SCHEMA_VERSION).toBe(35)` pin is also worth naming: it failed CI on every bump by design, which is what made an author stop and think. Nothing replaced it. This does not restore that — a digest has no literal to pin — but it does make the mechanism that took over the job visible to the next person who reads the file. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(spring): pin CLASS_SCHEMA's membership in the fingerprinted DDL set When `INCREMENTAL_SCHEMA_VERSION` went away, its sibling in basicblock-callee-ids-schema.test.ts got a replacement assertion tying BASICBLOCK_SCHEMA to the fingerprint's input set. This file's `>= 23` floor was deleted with nothing put in its place. The file still asserts CLASS_SCHEMA's CONTENT — that the `frameworkAnnotations` column exists — but not that CLASS_SCHEMA is part of what the digest covers, and the second is what makes an index built before that column carry a different fingerprint and get rebuilt. Mirrors the sibling so the two read the same way. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(identity): stop a symlinked directory from aborting the whole analyze `collectArtifacts` fused two orthogonal facts into one condition: that four directory names never carry runtime payload, and that a symlink where a real directory was assumed falls through to the payload branch, where `snapshotReadableFile` stats the target, sees a directory, and throws "Analyzer identity input is not a file". The second was only fixed for those four names. Every other symlinked directory in a scanned package root still aborted the run — `dist -> build`, a vendored grammar link, anything inside a linked sibling checkout. Newly reachable, because making workspace-linked packages scannable pointed the scanner at a live checkout instead of an immutable registry tarball for the first time. Split along the actual seam: prune on the NAME alone, and give symlinks their own branch in the type dispatch, ahead of the payload branch. Link text is recorded rather than followed. Following was rejected on three grounds, each checked in source: the traversal is a stack with no visited set, so a self-referential link would recurse to `runtimeDepth` — which throws, trading one hard abort for another; `snapshotDirectory` rejects a symlink outright, so the directory guard could not accept one without a realpath rewrite of its canonical-path identity; and a link into an already-scanned tree double-counts against `runtimeEntries`/`runtimeBytes`, which also throw. The cost is stated in code: a link out of the package contributes its text, not its target's content. Links resolving to a regular file keep the existing content digest. The new `'unfollowed-symlink'` kind is threaded through every consumer, including the cache validator — which re-probes with `mode: 'link'`, since the readable-file probe resolves the target and would return null for exactly this kind, silently failing every warm validation. No canonicalization or cache-schema bump. Digest content changes only for trees that previously crashed: a delta scan over all 258 scanned roots of this install found no regular file bearing a pruned name and no symlink failing to resolve to a file, so `dependencyRuntime.digest` is byte-identical here. Six of the eight new tests fail against the unfixed tree with the exact production error; all eight pass after. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(analyze): give the reuse gate a real seam and sanitize logs at the funnel Cleanup pass over the #2798 branch. Net -183 lines. The gate had no extracted predicate, so its own test asserted it by regex-matching run-analyze.ts SOURCE TEXT. That pinned production formatting: one pattern froze three back-to-back single-name imports from './lbug/schema.js', so merging them — the obvious tidy-up — failed a test named "still imports the DDL digest itself". `schemaFingerprintMismatch` and `isSchemaFingerprintShaped` now live in core/lbug/schema.ts beside the constant. Not in run-analyze.ts next to `pdgModeMismatch`, because storage/ must stay off the analyze pipeline and mcp/resources.ts is a plausible second consumer — the same reasoning that puts `cjkSegmentationModeMismatch` in core/search/. The regex block is gone; the test calls the predicate. The three imports are merged. ANSI sanitation moved from one field to the funnel. The per-field guard's own comment stated the general hazard — gitnexus.json is parsed with no runtime shape validation and the notice reaches console.log — while two sibling guards twelve lines away echoed `runnerIdentity.schemaVersion` and `cjkSegmentation` from that same file raw into the same log. `log()` now strips C0/C1 controls, covering all seven guard messages and any written later. Also: - Deleted a duplicate integration test. After the downgrade test was repointed at `schemaFingerprint` it became the same scenario as the new one, differing only by an extra log assertion — which is now folded into the survivor. Saves a fixture and two full pipeline runs per CI pass. - Replaced a 3-parameter set-difference helper with one set equality. Its doc was false at one call site (arguments semantically swapped) and it needed a fourth test purely to prove itself non-vacuous; set equality cannot go vacuous. - Removed ~115 lines of runner-identity table that duplicated analyzer-identity.test.ts. The three genuinely uncovered cases moved there, and the #2798 invariant — build digest moved while the DDL did not — now asserts against a REAL analyzer-build-tree edit rather than a hand-built literal, which is strictly stronger than what it replaces. - MIGRATION.md quoted a log line the code cannot emit; it was written before the placeholder changed. - Restored the rationale on the `capabilities` docstring, which a previous pass replaced with its consequence — leaving a maintainer reading "duplicated by hand" as a wart to fix by importing, which is what the original forbade. - Marked the `isIncremental` conjunct as belt-and-braces: `!options.force` short-circuits before it, so it cannot decide anything. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(analyze): force a rebuild when the vector column width changes `CodeEmbedding.embedding` is declared `FLOAT[EMBEDDING_DIMS]`, resolved from `GITNEXUS_EMBEDDING_DIMS` at module load. Nothing gated it. Flip the variable on a same-commit clean tree and no guard fired at all: `alreadyUpToDate` returned over a `FLOAT[384]` table while the process embedded at 768. The only reaction anywhere discards the embedding CACHE and re-embeds — into a column whose type it never revisits. This predates #2798; `INCREMENTAL_SCHEMA_VERSION` never covered dims either. It surfaced because the fingerprint work had to reason about why `EMBEDDING_SCHEMA` must stay OUT of the digest: its width is environment-derived, so folding it in would make the same build disagree with itself and thrash rebuilds. That exclusion is correct, and it leaves the width needing its own guard. Modelled on `cjkSegmentation`, the closest sibling: an env-resolved scalar stamped at write time and compared by a small exported predicate that forces on mismatch. `embeddingDimsMismatch` sits in core/lbug/schema.ts beside `EMBEDDING_DIMS`, so the query side can adopt it without importing the analyze pipeline — mcp/local/local-backend.ts already warns on a cjkSegmentation disagreement and has the identical claim here, since the query path embeds at the live width against a table of unknown width with no validation at all today. ABSENCE IS NOT A MISMATCH, deliberately. Forcing on it would be dead code: `embeddingDims` and `schemaFingerprint` ship together, and a missing fingerprint already forces exactly one rebuild — which is where this stamp lands. Absence also carries no signal here, unlike the fingerprint: a missing fingerprint means "DDL this build cannot vouch for" and ships WITH a DDL change, whereas a missing dims stamp means only "written before the field existed", and that run's table agreed with that run's width. Drift requires the env to change, which absence says nothing about. The `cjkSegmentation` trick of folding absence into the default was unavailable — there is no width that is safe to assume for an existing table — so the stamp is instead written unconditionally, giving absence exactly one meaning. Malformed values are not grandfathered: null, '384', NaN and objects all read as a mismatch and err toward a rebuild. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(mcp): warn when the served index's vector width differs from the query embedder's The analyze side now forces a rebuild when the vector column width changes. The query side had no equivalent: a serving process embeds a query at its own width and searches a table whose width was fixed when the index was built. Disagree and the user gets wrong or missing semantic results with nothing explaining why. Mirrors the cjkSegmentation drift warning immediately above it — same warnings[] array, same per-query recomputation, agent-visible in the tool response, and it warns rather than refuses. A width mismatch degrades the semantic lane only; keyword results are unaffected, so `partial` is deliberately not set. Compares against `getEmbeddingDims()` — the width the query embedder actually produces — NOT schema.ts's `EMBEDDING_DIMS`. The two diverge exactly when GITNEXUS_EMBEDDING_DIMS is set on a server that embeds LOCALLY: the query path ignores that variable and embeds at 384, so comparing against the env-derived constant would report drift on a lane that works fine. The recorded width is what the vector CAST actually binds. `embeddingDimsMismatch` is imported from core/lbug/schema.js rather than restated, so "absent is not a mismatch" cannot drift between the analyze and query sides. That predicate was placed in schema.ts precisely so this consumer could reach it without importing the analyze pipeline. Two gates keep it quiet when it would be noise: it fires only for a repo where this process actually produced a query vector, so an index analyzed without --embeddings (or a server whose embedder is unavailable) never carries it. An untrusted recorded value — meta.json is schema-less JSON — is reported as "an unrecognized width" rather than echoed. `loadMeta` is hoisted out of the neighbouring try so both diagnostics share one read and an invalid GITNEXUS_FTS_CJK_SEGMENTATION cannot take this one down with it. Refs #2798 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(identity): detect an npm-linked dev dependency the specifier cannot see `isLocallyLinkedSpecifier` admits a devDependency whose SPECIFIER is checkout-local. `npm link <pkg>` leaves the specifier a registry range while the node_modules entry symlinks to a checkout — locally linked, invisible to a specifier check, so a semantic-only edit there still moves neither digest. The obvious placement is unaffordable, measured rather than assumed: probing every dev-only name inside collectRuntimePackages costs 1998 resolutions, not the ~8 it looks like, because dependencyNames runs for every package in the BFS and published tarballs retain their devDependencies. Persisted path guards go 2221 -> 11050 (+398%), and every guard is re-probed on each warm validation — the path `status` takes. Scoped to the root package instead. The declared-intent half is untouched and still enumerated everywhere: it alone can emit the `<missing>` edge for a declared link whose checkout is absent, where resolution returns null and cannot distinguish that from an uninstalled dev tool. The new resolved-location half runs only when `parent.root === packageRoot`, resolves through the existing resolver so its path guards are recorded, and admits a name iff the realpath'd root carries no node_modules segment. Bounded against mis-fire by EXPANSION. "Not under node_modules" is a proxy for "checkout-local"; under a relocated pnpm virtual store every dev dep passes it and the whole dev tree folds into the receipt — against limits that THROW, so a legitimate install would abort. Measured here: uncapped, that shape takes 259 -> 347 packages and 2250 -> 3786 guards. The cap admits at most four and DROPS THE WHOLE CHANNEL on overflow rather than an arbitrary prefix, because the abort comes from the transitive payload of whichever trees get folded in — four of a mis-fired thirteen is still unbounded, and a sorted-prefix receipt would be arbitrary. Overflow falls back to the specifier-only receipt that ships today. Cost on this install: 259 packages unchanged, 13 dev names resolved, guards 2221 -> 2250 (+29, +1.3%). Verified against the real implementation, not just a replay: validation guards 16295 -> 16324, packageCount and artifactCount unchanged, and `dependencyRuntime.digest` byte-identical — so this forces no re-analysis for anyone. Each test fails on the defect it targets: disabling the channel kills the npm-link and cap cases; dropping the root-only scope makes the differential guard-count case fail at 2.8x guards; removing the specifier half kills the `<missing>` case.

The field that decides whether an existing index can be reused changed in
|
||||
`.gitnexus/gitnexus.json` (and in each `branches/<slug>/gitnexus.json`):
|
||||
`schemaVersion?: number` has been removed and `schemaFingerprint?: string`

||||
added. The new value is a 12-character digest of the graph DDL this build
|
||||
creates, so it *describes* the schema an index's tables were actually built
|
||||
from rather than asserting a number about it.
|
||||
|
||||
An absent fingerprint is treated as a mismatch, and that is the whole
|
||||
backward-compatibility story: every index written by an earlier GitNexus
|
||||
carries no fingerprint, so it is rebuilt exactly once.
|
||||
|
||||
### Do I need to migrate?
|
||||
|
||||
**No.** There is nothing to run, edit, or pass. The first `analyze` after
|
||||
upgrading logs one line —
|
||||
|
||||
```
|
||||
index schema changed (built by an unidentified GitNexus build, this build is <fingerprint>); forcing a full re-analyze so the database is recreated from the current schema.
|
||||
```
|
||||
|
||||
— and then performs that full re-analyze itself. The same run stamps the
|
||||
fingerprint, and every run after it takes the normal incremental path again.
|
||||
|
||||
### What happens on re-index?
|
||||
|
||||
One automatic full re-analyze, once per index. Nothing else changes; the
|
||||
resulting graph is what the current build would have produced anyway.

||||

The scope of that one-time cost is worth knowing before you hit it. It is
|
||||
per **index**, not per machine or per repository — branch-scoped index slots
|
||||
(#2106) each keep their own `gitnexus.json`, so every slot pays for itself
|
||||
the first time it is analyzed after the upgrade. On a very large repository
|
||||
a full re-analyze is substantial, not a blip; plan the first post-upgrade
|
||||
run accordingly.
|
||||
|
||||
### Why a digest instead of a version number?
|
||||
|
||||
`schemaVersion` was hand-incremented, and it had to predict something a
|
||||
number cannot know: whether the DDL an on-disk database was created from
|
||||
matches this build's. It collided with `main` eight times, twice *exactly* —
|
||||
and an exact clash was the quiet failure. Two builds stamp the same number
|
||||
over different DDL, the strict `===` reuse gate reads the index as current,
|
||||
the `CREATE … TABLE` statements are skipped as "already exists", and edges
|
||||
whose endpoint pair the live database cannot persist are dropped. A wrong
|
||||
graph, with no error anywhere.
|
||||
|
||||
A derived digest cannot fail that way: two builds agree exactly when their
|
||||
DDL agrees, so concurrent branches never need renumbering and a mismatch is
|
||||
always a real mismatch. The retired ladder's per-version rationale (v2
|
||||
`BasicBlock.callees` through v35's generated relation cross-product) now
|
||||
lives only in git history:
|
||||
`git show 561f913a3:gitnexus/src/storage/repo-manager.ts`.
|
||||
|
||||
### What about rollback?
|
||||
|
||||
Downgrading to an older GitNexus is safe. The older binary looks for
|
||||
`schemaVersion`, does not find one, treats the index as pre-versioning, and
|
||||
forces its own full rebuild — the same one-time cost in the other direction,
|
||||
never a stale or mismatched graph.
|
||||
|
||||
### What if I alternate between an old and a new binary?
|
||||
|
||||
Every switch forces a rebuild. The end-of-run metadata is written as a fresh
|
||||
object literal rather than merged over the previous file, so a new build's
|
||||
write drops `schemaVersion` and an old build's write drops
|
||||
`schemaFingerprint` — neither field survives the other's run, and each binary
|
||||
then finds its own gate unsatisfied. This hits anyone running a pinned
|
||||
`npx gitnexus@<version>` alongside a local build, or an editor hook still on
|
||||
an older release. It is a cost, not a correctness problem: each run rebuilds
|
||||
against its own schema, and the graph it serves is correct for the binary
|
||||
that produced it. Pin one version per index to avoid the churn.

|

* `fallbackRelationshipInserts`' bare `catch`. A wrong graph, not an error.
|

*
|

|

* resolved, almost always the 384 default, and it was consistent with the
|
||||
* table it wrote. Drift needs the env to CHANGE, which absence says nothing
|
||||
* about.

* - Forcing on absence would buy no safety anyway. Every index that lacks this
|
||||
* stamp also lacks `schemaFingerprint` (both landed together in #2798), and
|
||||
* that guard already forces a rebuild for exactly those indexes — after
|
||||
* which the width is stamped and the hazard is closed for good. A second
|
||||
* trigger for the same one rebuild is dead weight that would keep firing
|
||||
* forever on any future path that legitimately omits the stamp.
|
||||
* - The cost of guessing wrong is asymmetric: a fleet-wide full re-analyze
|
||||
* (minutes to hours per repo) for a hazard that requires a rare, deliberate
|
||||
* env change.
|
||||
*
|
||||
* Absence is precisely `undefined`. Any other recorded value that is not this
|
||||
* build's width — including a malformed one, since `meta.json` is a schema-less
|
||||
* `JSON.parse` of on-disk state — reads as a mismatch and errs toward a

|
||||
* Lives here rather than in run-analyze for the reason

* force a full re-analyze instead (same contract as v2–v6).
|

|

* v9: Java enum constant bodies joined the instance model and anonymous
|
||||
* naming switched to JLS 13.1 immediately-enclosing-type chains (#2555): `enum E { A {
|

* on unchanged files; force a full re-analyze.
|

* v10: Java `record_declaration` now emits a first-class `Record` graph node
|

* (#2564): a record's container node was previously never created (JAVA_QUERIES
|

* had no capture for it), so its methods existed as ownerless Method nodes
|

|

|
||||
* v11: Rust abstract trait methods (`fn foo(&self) -> T;`, no body) now get a

* scope + declaration capture (#2604): RUST_SCOPE_QUERY had no
|
||||
* `function_signature_item` pattern, so a `&dyn Trait` receiver could never

|
||||
* unchanged Rust trait file; force a full re-analyze instead.
|

|
||||
* (#2514): a function/struct name defined three or more times used to

||||
* re-resolve to the last-scanned file (a presence toggle), so odd duplicate
|

* counts emitted a wrong cross-file CALLS edge. Same v7/v11 contract: the

|
||||
* pre-v12 index would keep these spurious CALLS edges on every unchanged Rust
|

|
||||
* RESOLVES import-disambiguated duplicate names (`for item in make()` /
|
||||
* `let Struct { f } = ..` where a `use` or `use x::*` import pins one of several
|
||||
* same-named definitions) to the imported definition's type. Both the removed

* spurious edges and these new resolved edges are cross-file, so a pre-v12
|
||||
* top-up would leave unchanged Rust files stale either way; force a full
|
||||
* re-analyze instead.
|
||||
* v13: Java local classes, enums, records, and interfaces use
|
||||
* source-type-relative JLS 13.1 identities (`Outer$1Local`). Number allocation
|
||||
* matches javac: one sequence per (enclosing type, local simple name), with a

||||
* separate sequence for anonymous types. Existing type/member ids, lexical
|
||||
* bindings, and ownership edges must not be mixed with newly named unchanged
|
||||
* Java files; force a full re-analyze.
|
||||
* v14: C# and Kotlin free-call fallback now rejects same-file methods whose
|
||||
* instance owner is outside the caller's enclosing class/MRO (#2563). The
|
||||
* incremental write set would otherwise retain those stale CALLS edges on
|
||||
* every unchanged C# and Kotlin file; force a full re-analyze instead.
|
||||
* v15: `const X = <arrow | function-expression>` no longer emits an edgeless
|
||||
* `Const:<file>:X` twin beside its `Function` node (#2687). The incremental
|
||||
* write set only covers changed files, so every unchanged TS/JS file would
|
||||
* keep its twin and `impact`/`context` would stay ambiguous on those names;
|
||||
* force a full re-analyze instead.
|
||||
* v16: calls through a closure-valued binding (`val f = { }; f()`) now resolve
|
||||
* in Kotlin, Swift, Dart, Ruby, Java, C# and PHP (#2693). These are NEW `CALLS`
|
||||
* edges, and those languages also gain callable graph nodes for closure
|
||||
* bindings that previously carried a value label or no node at all (including
|
||||
* JS/TS `var f = () => {}`). The incremental write set only covers changed
|
||||
* files, so unchanged files would keep reporting a zero blast radius for those
|
||||
* symbols; force a full re-analyze instead.
|
||||
* v17: `this` inside a JS/TS ordinary `function` no longer resolves to the
|
||||
* lexically enclosing class (#2701). This REMOVES `CALLS`/`ACCESSES` edges —
|
||||
* including ones that are correct at runtime via `.bind(this)`, `.call`, or a
|
||||
* `forEach` thisArg, which the graph does not model. The incremental write set
|
||||
* only covers changed files, so every unchanged TS/JS file would keep its
|
||||
* fabricated `this` edges; force a full re-analyze instead.
|
||||
* v18: function-local callables carry their enclosing-callable chain plus their
|
||||
* own position, so a local closure no longer shares a node id with a same-named
|
||||
* file-level function (#2699) — `Function:f.ts:save` ->
|
||||
* `Function:f.ts:run.save@2:2`. JavaScript/TypeScript also gain block scopes
|
||||
* (`statement_block`), without which two `const` of one name in sibling blocks
|
||||
* stay indistinguishable to the resolver and each call resolves to BOTH. This
|
||||
* CHANGES PERSISTED NODE IDS for every function-local callable and changes
|
||||
* which node a local call resolves to. An incremental top-up would leave
|
||||
* unchanged files pointing at the old ids while changed files emit the new
|
||||
* ones, splitting each symbol in two; force a full re-analyze instead.
|
||||
* v19: the enclosing-callable walk now stops at class BODIES and anonymous-class
|
||||
* construction sites, not only at class DECLARATIONS (#2699 follow-up). v18 shipped
|
||||
* with `CLASS_CONTAINER_TYPES` as the only boundary, which lists no node for a Java
|
||||
* anonymous class (`object_creation_expression > class_body`), so the walk reached the
|
||||
* enclosing method and re-keyed `Worker$1.run` as `Worker.makeHandler.run@7:12` —
|
||||
* destroying the javac-compatible JLS identity of #2550/#2555/#2562. An index stamped
|
||||
* v18 therefore holds WRONG Java ids, and without this bump it passes the reuse gate
|
||||
* and keeps them on every unchanged file; force a full re-analyze instead.
|
||||
* v20: a NAMED explicit receiver no longer resolves its member through the lexical
|
||||
* scope chain (#2699 follow-up). `options.baseUrl` used to bind to an unrelated
|
||||
* function-local `const baseUrl`; measured on a 762-file corpus this removes 709
|
||||
* such edges and adds none. `this`/`self` are exempt, so the 2 genuine self-alias
|
||||
* reads it also covered are kept. A v19 index holds those false CALLS/ACCESSES on
|
||||
* every unchanged file and would keep serving them through the reuse gate; force a
|
||||
* full re-analyze instead.
|
||||
* v21: a closure bound to a name is a call SOURCE in every language, not only a
|
||||
* TARGET (#2699 part B). PHP/Rust/Kotlin/Ruby/Dart closure bindings gained the
|
||||
* declaration rule, Rust gained the graph NODE it never emitted, and Dart locals
|
||||
* gained the enclosing-callable + position identity that made two same-named
|
||||
* closures collapse onto one node — which had them asserting a CALLS edge
|
||||
* present nowhere in the source. All of that changes emitted node ids AND edges
|
||||
* on files that did not themselves change, so a v20 index topped up
|
||||
* incrementally keeps serving the old attribution; force a full re-analyze.
|
||||
*
|
||||
* v22: CommonJS export forms are indexed (#2723) — `exports.X`/`module.exports.X`,
|
||||
* aliased receivers, module-level `this`, re-export forwarding, `module.exports = fn`,
|
||||
* plus prototype/`this` members as Methods with owner edges; and the #2729 review
|
||||
* fixes that stopped a text-only exports receiver inventing exports inside UMD
|
||||
* factories and stopped the shadow guard deleting or fabricating call edges.
|
||||
* These change what is emitted for source whose CONTENT has not changed, so a v21
|
||||
* index would keep serving the pre-fix graph for every unchanged CommonJS file —
|
||||
* the exact "Target not found" symptom #2723 reported. Force a full re-analyze.
|
||||
* v23: Rust module-qualified calls resolve against the module tree (#2730).
|
||||
* RUST_SCOPE_QUERY gained `@declaration.namespace` on `mod_item` and
|
||||
* `@reference.qualified-name` on scoped call sites, and a new resolution tier
|
||||
* binds `tools::dispatch(..)` to the module the path names instead of the
|
||||
* lexically nearest same-named fn. Same v11/v12 contract: the incremental
|
||||
* write set only covers CHANGED files, so a top-up against a pre-v23 index
|
||||
* would keep the wrong self-loop — and keep reporting the callee as unreached
|
||||
* — for every unchanged Rust file, which is exactly the symptom #2730
|
||||
* reported. Force a full re-analyze.
|
||||
*
|
||||
* v28: structural receiver typing is active for ALL 14 languages, and the fold no
|
||||
* longer types a bare identifier that merely SHADOWS a class name as that class.
|
||||
* v27 landed with TypeScript-only emission and with the permissive base lookup, so
|
||||
* an index stamped 27 by an intermediate build carries both pre-rollout edges for 13
|
||||
* languages AND the fabricated edges the shadowing bug produced. The reuse gate is a
|
||||
* strict `===`, so such an index would be treated as current. Re-bumped here so the
|
||||
* version tracks the final edge semantics. Force a full re-analyze.
|
||||
*
|
||||
* v26: receiver expressions are typed from captured structure rather than from
|
||||
* their source text. `svc?.getUser().save()`, `svc!.getUser().save()` and
|
||||
* `svc.getTyped<User>().save()` previously emitted NO `CALLS` edge — the text
|
||||
* cascade split the receiver on punctuation it could not parse — and two of the
|
||||
* three recorded no drop either, because a later case marked the site handled,
|
||||
* which suppresses the drop record. So the caller was missing from
|
||||
* `impact(direction: "upstream")` and `context()` AND the count still claimed
|
||||
* `epistemic: 'exact'`. Same v11/v12 contract: the incremental write set covers
|
||||
* only CHANGED files, so a top-up against a pre-v26 index keeps serving the
|
||||
* pre-fix graph — and the pre-fix confident count — for every unchanged file.
|
||||
* Worse than merely incomplete: the drop summary is a whole-repo recompute while
|
||||
* the edges are a changed-files write, so the two would disagree. Force a full
|
||||
* re-analyze.
|
||||
*
|
||||
* v24: inline constructor receivers resolve — `Service(db).do_work()` (Python),
|
||||
* `new Service(db).doWork()` (JS/TS, C#), `Service.new.do_work` (Ruby), plus the
|
||||
* generic, qualified, chain-head and keyword-trivia spellings of the same shape
|
||||
* (#2708). These calls previously emitted NO `CALLS` edge, so the caller was
|
||||
* missing from `impact(direction: "upstream")` and `context()`. The Ruby
|
||||
* selector fix also moves an edge: `factory.new.run`, where the class defines an
|
||||
* instance method named `new`, now resolves through that method again instead of
|
||||
* being read as construction. All of it changes what is emitted for source whose
|
||||
* CONTENT has not changed, so a v22 index topped up incrementally — or served by
|
||||
* the same-commit "already up to date" fast path — keeps returning the pre-fix
|
||||
* graph for every unchanged file, which is exactly the missing-caller symptom
|
||||
* #2708 reported. Force a full re-analyze.
|
||||
*

||||
* v29: Spring @Bean declarations are CodeElement providers and INJECTS may run
|
||||
* from a consumer Class or factory Method to that CodeElement (#2413). The

* relation DDL gained Class→CodeElement; a pre-v29 database cannot persist that
|
||||
* label pair, so force a one-time rebuild against the expanded schema.

||||
* (`unresolvedReceiverMembers`) so `impact()`/`context()` can report
|
||||
* `epistemic: 'lower-bound'` instead of a confident `'exact'` when a call site
|
||||
* was dropped for want of a receiver type (#2744). A pre-v26 index carries no
|
||||
* such summary, and an absent summary is indistinguishable from "nothing was
|
||||
* dropped" — so topping one up incrementally would keep reporting `exact` for
|
||||
* exactly the symbols the signal exists to flag. Force a full re-analyze.
|
||||
*
|
||||
* (This shipped as v25 on its own branch; `main` took 25 for #2742 first, so it
|
||||
* is renumbered here. Re-check both constants against origin/main immediately
|
||||
* before merging — this is the fourth time that collision has bitten.)
|
||||
*
|
||||
* v25: Rust items are qualified by their enclosing `mod` chain (#2742), so
|
||||
* `mod inner { fn dispatch }` and a crate-root `fn dispatch` in one file are
|
||||
* finally DISTINCT nodes instead of collapsing onto `Function:<file>:dispatch`
|
||||
* first-wins. Node IDS CHANGE for every Rust item inside any `mod` block —
|
||||
* `#[cfg(test)] mod tests` makes that close to every Rust repo — so a pre-v25
|
||||
* index holds ids an incremental top-up cannot reconcile and would simply
|
||||
* strand. Force a full re-analyze.
|
||||
*
|
||||
* v30: bound-callable graph `startLine` follows the initializer (#2735), so a
|
||||
* multi-line closure binding joins the scope channel and emits its CALLS edge.
|
||||
* Pre-v30 indexes keep the wrapper line on unchanged files and would keep
|
||||
* failing closed (no edge) through the reuse gate. Force a full re-analyze.
|
||||
*
|
||||
* v31: Python named imports that resolve to concrete submodules are finalized
|
||||
* as namespace edges (#2746), enabling qualified constructor and method CALLS
|
||||
* edges. Pre-v31 indexes retain the old package-target/missing-edge graph for
|
||||
* unchanged files through the reuse gate. Force a full re-analyze.
|
||||
*
|
||||
* v32: the relation DDL (the single shared `CodeRelation` REL TABLE) gains
|
||||
* sixteen FROM/TO pairs carried by `HAS_METHOD`/`HAS_PROPERTY` and
|
||||
* scope-resolution edges: Enum→{Function, Method, Struct, Constructor,
|
||||
* Property, TypeAlias}, Property→{Class, Enum, Function, Struct},
|
||||
* Method→{Variable, Const}, Trait→Function, Impl→Function, Const→Method and
|
||||
* Variable→Method. The Enum/Property set was observed on Swift (enums carry
|
||||
* computed properties, methods, initializers and nested types) and is also
|
||||
* reached by Java/PHP enum members; Trait/Impl→Function covers a Rust
|
||||
* `impl`/`trait` method, which is minted as a `Function` node, not `Method`;
|
||||
* Const/Variable→Method and its sibling Method→Const cover a JS/TS object
|
||||
* literal's shorthand methods, whose owner is labelled `Const`/`Variable`. A
|
||||
* pre-v32 database physically lacks these from-to pairs — see
|
||||
* `assertDeclaredPair` (rel-pair-routing.ts) for why an incremental top-up
|
||||
* fails loudly on one path and silently on the other. Force a full re-analyze.
|
||||
*
|
||||
* (This shipped as v31 on its own branch; `main` took 31 for #2746 first, so
|
||||
* it is renumbered here. Re-check both constants against origin/main
|
||||
* immediately before merging — this is the sixth time that collision has
|
||||
* bitten. If this change is ever reverted, do not free 32 for reuse — the
|
||||
* reuse gate is exact equality, so an index already stamped 32 would satisfy
|
||||
* it against a differently-shaped reverted DB. Start the next allocation at
|
||||
* 33 instead.)
|
||||
*
|
||||
* v33: Spring AOP evidence adds the Interface→CodeElement relation pair
|
||||
* (#2416). LadybugDB fixes allowed endpoint pairs when the relation table is
|
||||
* created, so an older index cannot persist these edges through incremental
|
||||
* writeback. Force a full re-analyze.
|
||||
*
|
||||
* v34: receiver-chain wire format v2 (name-free `await` / `index` steps). Every
|
||||
* persisted `ReferenceSite.receiverChain` string changed prefix, and a v2
|
||||
* decoder refuses a v1 payload by design, so a pre-v34 index carries chains this
|
||||
* build cannot read. Resolution would silently fall back to the text cascade for
|
||||
* every chain-carrying site — no error, just quietly worse edges. Force a full
|
||||
* re-analyze.
|
||||
*
|
||||
* Numbered 34, not 33: `main` took 33 for Spring AOP (#2416) mid-flight, landing
|
||||
* on exactly this branch's number — the seventh collision in this series and the
|
||||
* first exact clash. Re-check against origin/main before merge.
|
||||
*
|
||||
* v35: the relation DDL is GENERATED from two closed-form rules instead of the
|
||||
* pairs someone happened to hit — 223 → 450 declared pairs (#2792, #2793).
|
||||
* Rule 1, the scope-resolution bridge: `LINKABLE_LABELS` + the `File` caller
|
||||
* fallback, crossed with `LINKABLE_LABELS` + `CALL_TARGET_TYPES`. Rule 2, the
|
||||
* phase/framework overlays: every definition label (`NODE_TABLES` minus
|
||||
* Community/Process/Route/Tool/Folder/BasicBlock) crossed with the labels those
|
||||
* emitters mint and hang off a resolved anchor — Annotation, Community,
|
||||
* Process, Route, Tool, File, Record. In both families the endpoint labels are
|
||||
* LOOKUP RESULTS, not literals at the emit site, so hand-listing could only
|
||||
* ever declare the pair in the latest stack trace: v32, v33 and #2781 were each
|
||||
* that same piecemeal fix, and `analyze` kept aborting at `assertDeclaredPair`
|
||||
* on the next codebase with a different edge shape (`Class→Variable` on Java
|
||||
* initializers, then `Method→Annotation` on Spring `@Bean`, `Method→File` on a
|
||||
* Vue Options-API handler, `Namespace→Record` on COBOL `DECLARATIVES`, and
|
||||
* `Class→Tool` on `@mcp.tool()` applied to a class — four at once, from three
|
||||
* different emitters). What remains hand-declared is only the containment /
|
||||
* inheritance / import surface, which no label predicate describes and which a
|
||||
* corpus test guards instead. A pre-v35 database physically lacks all of these
|
||||
* from-to pairs, so force a full re-analyze.

|

* Symbolic-link handling in the analyzer runtime-payload scan (#2798).
|
||||
*
|
||||
* `collectArtifacts` used to fuse two unrelated facts into one condition:
|
||||
* "this name is never runtime payload" and "a symlink must not reach the
|
||||
* file-payload branch". Only the four pruned names got the symlink half, so any
|
||||
* OTHER symlinked directory inside a scanned package root — `dist -> build`, a
|
||||
* vendored-grammar link, anything in a workspace-linked sibling checkout — fell
|
||||
* through to `snapshotReadableFile`, which stats the target, sees a directory,
|
||||
* and throws `Analyzer identity input is not a file`, aborting the whole
|
||||
* analyze. Workspace-linked packages became scannable on this branch, so the
|
||||
* crash is newly reachable (this worktree's own `gitnexus-shared/node_modules`
|
||||
* is a symlink).
|
||||
*
|
||||
* These tests pin the split: prune by NAME alone, and route every symlink that
|
||||
* does not resolve to a regular file into a link-text artifact instead of the
|
||||
* payload branch.

/**

* #2798 — SCHEMA_FINGERPRINT, the derived half of the incremental reuse gate.
|
||||
*
|
||||
* The replaced `INCREMENTAL_SCHEMA_VERSION` was hand-picked and had to PREDICT whether an
|
||||
* on-disk database was created from this build's DDL. It clashed exactly
|
||||
* with a concurrently-merged branch twice, and the gate was a strict `===`, so
|
||||
* such an index read as current while its tables physically could not hold the
|
||||
* edges the build emitted. The fingerprint derives that fact instead, and is now
|
||||
* the only schema gate.
|
||||
*
|
||||
* These tests pin the three properties the gate depends on:
|
||||
* 1. it covers the DDL that is actually executed (input-set pinning);
|
||||
* 2. it is a function of CODE, never of the environment;
|
||||
* 3. it moves when any covered DDL string moves.
