 Notes: `offset` ≥ `total` returns an empty page (with `total` still reported). Out-of-range or malformed `limit`/`offset` (non-integer, `limit` outside `[1, 200]`, `offset < 0`) are rejected with a clear error — `limit` above the max is rejected, not silently capped. The order is deterministic (lower-cased name, then path), so paging never skips or duplicates an entry while the registry is unchanged.
 
+### Inline staleness signal (`query` / `context` / `impact` / `cypher`)
+
+These four hot read tools attach a non-blocking `staleness` field to their response when the index is behind the checkout's current HEAD — the same `{ commitsBehind, hint }` shape `list_repos` already reports — so a direct tool call surfaces a behind-HEAD index without a separate `list_repos` call:
+
+```jsonc
+{ /* …the tool's normal result… */
+  "staleness": { "commitsBehind": 3, "hint": "⚠️ Index is 3 commits behind HEAD. Run analyze tool to update." }
+}
+```
+
+The field is **absent when the index is current** (or when the freshness check can't run), so its presence is the signal. It is only ever added to object results — raw-array `cypher` output and error envelopes are returned unchanged. `@group`-targeted calls do not carry it (multi-repo staleness is ill-defined). When you see it, the graph may be behind the working tree — re-run `analyze` before trusting blast-radius or dependence answers.
+
 ### Taint findings (`explain`)
 
 `explain` returns taint findings recorded by `gitnexus analyze --pdg` — intra-procedural `TAINTED` edges plus cross-function `TAINT_PATH` hops where the interprocedural taint phase found a function-level source→sink chain. Each finding includes a sink category (command-injection, code-injection, path-traversal, sql-injection, xss), source/sink lines, and the ordered hop path with the variable carried on each hop.

-This project is indexed by GitNexus as **GitNexus** (22756 symbols, 58464 relationships, 300 execution flows). Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.
+This project is indexed by GitNexus as **GitNexus** (248612 symbols, 565510 relationships, 918 execution flows). Use GitNexus graph tools to understand code, assess impact, and navigate safely.
 
 > Index stale? Run `node .gitnexus/run.cjs analyze` from the project root — it auto-selects an available runner. No `.gitnexus/run.cjs` yet? `npx gitnexus analyze` (npm 11 crash → `npm i -g gitnexus`; #1939).
 
 ## Always Do
 
-- **MUST run impact analysis before editing any symbol.** Before modifying a function, class, or method, run `impact({target: "symbolName", direction: "upstream"})` and report the blast radius (direct callers, affected processes, risk level) to the user.
-- **MUST run `detect_changes()` before committing** to verify your changes only affect expected symbols and execution flows. For regression review, compare against the default branch: `detect_changes({scope: "compare", base_ref: "main"})`.
+- **MUST run impact analysis before editing.** Use `impact({target: "symbolName", direction: "upstream"})` (MCP) or `node .gitnexus/run.cjs impact "symbolName" --direction upstream --repo .` (CLI fallback); report callers, processes, and risk. Never substitute grep for graph analysis. For unified PDG impact, add `mode: "pdg"` with optional `line: <N>` — it returns statement-level `affectedStatements` over CDG + REACHING_DEF and inter-procedural symbols in `interproceduralByDepth`/`byDepth`; no-layer/degraded PDG results are UNKNOWN-risk notes (`--pdg` layer). CLI equivalent: `node .gitnexus/run.cjs impact "symbolName" --direction upstream --mode pdg --line <N> --repo .`.
+- **MUST analyze graph changes before committing.** Use `detect_changes({scope: "all"})` (MCP) or `node .gitnexus/run.cjs detect-changes --scope all --repo .` (CLI fallback). For regression review: `detect_changes({scope: "compare", base_ref: "main"})` or `node .gitnexus/run.cjs detect-changes --scope compare --base-ref "main" --repo .`.
 - **MUST warn the user** if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
 - When exploring unfamiliar code, use `query({search_query: "concept"})` to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
 - When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use `context({name: "symbolName"})`.
 - For security review, `explain({target: "fileOrSymbol"})` lists taint findings (source→sink flows; needs `analyze --pdg`).
+- For control/data dependence, `pdg_query({mode: "controls", target: "fileOrSymbol"})` answers "under what condition does X run?" (CDG, incl. guard clauses) and `pdg_query({mode: "flows", target, variable})` traces "where does variable Y flow?" (REACHING_DEF). `--pdg` layer.
 
 ## Never Do
 
-- NEVER edit a function, class, or method without first running `impact` on it.
+- NEVER edit a function, class, or method before MCP/CLI impact analysis.
 - NEVER ignore HIGH or CRITICAL risk warnings from impact analysis.
 - NEVER rename symbols with find-and-replace — use `rename` which understands the call graph.
-- NEVER commit changes without running `detect_changes()` to check affected scope.
+- NEVER commit before MCP/CLI graph change analysis.

 `query`, `context`, and `impact` are group-aware: pass `repo: "@<groupName>"` (or `"@<groupName>/<memberPath>"` to scope to one member) plus optional `service: "<monorepo/path>"`. Group-mode `query` merges per-repo results via Reciprocal Rank Fusion; group-mode `impact` runs the local walk in the chosen member and fans out across boundaries via the Contract Bridge (`gitnexus/src/core/group/cross-impact.ts`). `trace` is also group-aware via `repo: "@<groupName>"` — but, unlike the others, it resolves `from`/`to` across **all** members (a `@<groupName>/<memberPath>` suffix is advisory for trace, not a scope); pass `from_uid`/`to_uid` to disambiguate a symbol name that occurs in more than one member.
 
 Group-mode `trace` (`gitnexus/src/core/group/cross-trace.ts`) stitches a path that crosses repositories: it resolves `from`/`to` across all members, and when they live in different repos it joins the home-repo segment to the target-repo segment over a single `ContractLink` boundary (an HTTP consumer→provider link, joined on `Contract.symbolUid`), reported as a `CONTRACT_LINK` hop in `crossings[]`. The crossing is clamped to one boundary (`MAX_SUPPORTED_CROSS_DEPTH`, shared with cross-impact); deeper `crossDepth` is reported via `notes[]`. With `pdg: true` (experimental, opt-in), each boundary-adjacent segment is enriched with its intra-procedural REACHING_DEF data-flow when that repo was indexed with `--pdg` (reusing the same anchored `flows` query as `pdg_query`); data flow never crosses the repo boundary, and a missing PDG layer degrades to call-level hops with a note. Two stores meet only at the `symbolUid` grain — the per-repo PDG/call graph and the group bridge — so this is the documented join; full cross-program (SDG-like) data flow across the boundary remains deferred (see `docs/plans/2026-06-18-002-feat-unified-pdg-impact-evaluation-plan.md`). The previously-planned `group_query`, `group_context`, `group_impact`, `group_contracts`, `group_status` MCP tools are intentionally not introduced — group-level state is exposed via resources instead:

 Standalone (regex-based) providers such as COBOL participate via `ScopeResolver.scopeResolutionEdgeMode: 'callable-flow-only'`: `runScopeResolution` runs for them, but every ordinary emission path — heritage, interface implementations, receiver-bound, free-call fallback, reference/import edges, post-resolution hooks — is gated off, so their legacy phase (e.g. `cobolPhase`) remains the sole owner of structural edges and the callable solver's `CALLS` are purely additive. A callable-flow-only provider whose files emitted no callable facts exits early, before finalize, keeping the opt-in proportional to source scanning.
 
+### Receiver chains and the drop census (#2766)
+
+A compound receiver (`svc.getUser().address.save()`) is captured as a compact string on `ReferenceSite.receiverChain`. `utils/receiver-chain-codec.ts` is the ONE encoder/decoder — capture emitters, the scope-resolution fold, and the durable ParsedFile store all import it rather than hand-rolling the format.
+
+Wire format is **v2**: `2|<base>|<step>|<step>…`, one-character version prefix, then base-first steps, each a one-character kind sigil plus the member name (`c` = call, `f` = field). `a` (await) and `i` (index) are **name-free** and encode as a bare sigil — an awaited call's name already lives on its `c` step, and a subscript key is a value, not a lookup-able identifier. The version went 1 → 2 when those two kinds were added, and a decoder REFUSES a foreign version rather than decoding the prefix it understands: a chain missing its await/index hop decodes cleanly as a different, shorter chain and would type the receiver against the wrong member. The format is unescaped (`|` and `~` cannot occur in an identifier), so an unencodable name is refused rather than escaped, and the payload is capped at `MAX_RECEIVER_CHAIN_BYTES` / `MAX_CHAIN_DEPTH` steps. Because these strings live in the incremental parse cache and the durable ParsedFile store, a format change requires a `PARSE_CACHE_VERSION` schema bump — a stale cache would otherwise replay v1 chains this build discards.
+
+Receivers the resolver could not type are not silently dropped. Each records a `ResolutionOutcome` (`scope-resolution/resolution-outcome.ts`) carrying the receiver's *shape* (`classifyReceiverShape`: `chain-call` / `chain-field` / `chain-mixed` / `chain-unwrap` / `no-chain` — the bench censuses these) and its *origin* (`in-program` / `external` / `unknown`). `scope-resolution/unresolved-receivers.ts` aggregates them per member name into the index-persisted `unresolvedReceiverMembers` summary, keeping in-program and external counts under separate keys. Only in-program drops make a count short: an external-rooted call (`System.out.println`, `fetch(...)`) has no in-graph node an edge could have reached, so it is reported but does not hedge. `impact` / `context` read that summary and publish `epistemic: 'exact' | 'lower-bound'`, prose `boundaries`, and the machine-readable `causes` split (`EpistemicCauses` in `mcp/local/local-backend.ts`).

 ### Optional CFG/PDG emission (`--pdg`, #2081–#2086)
 
 On a `--pdg` run the parse worker builds a per-function control-flow graph from the tree-sitter AST (`LanguageProvider.cfgVisitor`; TypeScript/JavaScript today) and serializes it onto `ParsedFile.cfgSideChannel` as plain data. Scope-resolution then emits the program-dependence layers from that side-channel **inside Phase 4 of `runScopeResolution`, while the disk-backed ParsedFile store is still live** — the only window where the worker-built CFGs are loaded (the store is cleared right after the phase returns). A standalone post-`mro` phase would read an empty store, so the emit deliberately lives in-phase, mirroring the `applyCaptureSideChannel` pattern. The opt-in is off by default (graph byte-identical), folded into the parse-cache key (a pdg-off warm cache is never reused on a `--pdg` run), and each layer is bounded by a per-function edge cap that logs any dropped edges. All layers are `BasicBlock → BasicBlock` edges in the single `CodeRelation` table, keyed by `type`; there is **no** `Function → BasicBlock` edge — the symbol↔block join is reconstructed from the BasicBlock id prefix + line span. The layers build on each other:
 
-- **M1 — CFG** (#2081): `BasicBlock` nodes + `CFG` edges. Edge *kind* (`seq`/`cond-true`/`loop-back`/…) rides the `reason` column (CFG is one `CodeRelation` type, not one per kind).
+- **M1 — CFG** (#2081): `BasicBlock` nodes + `CFG` edges. Edge _kind_ (`seq`/`cond-true`/`loop-back`/…) rides the `reason` column (CFG is one `CodeRelation` type, not one per kind).

-This project is indexed by GitNexus as **GitNexus** (22756 symbols, 58464 relationships, 300 execution flows). Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.
+This project is indexed by GitNexus as **GitNexus** (248612 symbols, 565510 relationships, 918 execution flows). Use GitNexus graph tools to understand code, assess impact, and navigate safely.
 
 > Index stale? Run `node .gitnexus/run.cjs analyze` from the project root — it auto-selects an available runner. No `.gitnexus/run.cjs` yet? `npx gitnexus analyze` (npm 11 crash → `npm i -g gitnexus`; #1939).
 
 ## Always Do
 
-- **MUST run impact analysis before editing any symbol.** Before modifying a function, class, or method, run `impact({target: "symbolName", direction: "upstream"})` and report the blast radius (direct callers, affected processes, risk level) to the user.
-- **MUST run `detect_changes()` before committing** to verify your changes only affect expected symbols and execution flows. For regression review, compare against the default branch: `detect_changes({scope: "compare", base_ref: "main"})`.
+- **MUST run impact analysis before editing.** Use `impact({target: "symbolName", direction: "upstream"})` (MCP) or `node .gitnexus/run.cjs impact "symbolName" --direction upstream --repo .` (CLI fallback); report callers, processes, and risk. Never substitute grep for graph analysis. For unified PDG impact, add `mode: "pdg"` with optional `line: <N>` — it returns statement-level `affectedStatements` over CDG + REACHING_DEF and inter-procedural symbols in `interproceduralByDepth`/`byDepth`; no-layer/degraded PDG results are UNKNOWN-risk notes (`--pdg` layer). CLI equivalent: `node .gitnexus/run.cjs impact "symbolName" --direction upstream --mode pdg --line <N> --repo .`.
+- **MUST analyze graph changes before committing.** Use `detect_changes({scope: "all"})` (MCP) or `node .gitnexus/run.cjs detect-changes --scope all --repo .` (CLI fallback). For regression review: `detect_changes({scope: "compare", base_ref: "main"})` or `node .gitnexus/run.cjs detect-changes --scope compare --base-ref "main" --repo .`.
 - **MUST warn the user** if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
 - When exploring unfamiliar code, use `query({search_query: "concept"})` to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
 - When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use `context({name: "symbolName"})`.
 - For security review, `explain({target: "fileOrSymbol"})` lists taint findings (source→sink flows; needs `analyze --pdg`).
+- For control/data dependence, `pdg_query({mode: "controls", target: "fileOrSymbol"})` answers "under what condition does X run?" (CDG, incl. guard clauses) and `pdg_query({mode: "flows", target, variable})` traces "where does variable Y flow?" (REACHING_DEF). `--pdg` layer.
 
 ## Never Do
 
-- NEVER edit a function, class, or method without first running `impact` on it.
+- NEVER edit a function, class, or method before MCP/CLI impact analysis.
 - NEVER ignore HIGH or CRITICAL risk warnings from impact analysis.
 - NEVER rename symbols with find-and-replace — use `rename` which understands the call graph.
-- NEVER commit changes without running `detect_changes()` to check affected scope.
+- NEVER commit before MCP/CLI graph change analysis.

+6. **Never `terminate()` a worker that may be inside a native call** — killing a worker thread mid-N-API aborts the entire process (`Napi::Error` → `std::terminate` → SIGABRT, #2432), so a timeout meant to trigger a graceful fallback takes the whole run down instead. Any worker running native code (tree-sitter grammars, LadybugDB, Icebug) must either reach a JS-visible safe point first — the parse pool's `shutdownDrainMs` handshake in `src/core/ingestion/workers/worker-pool.ts` — or be abandoned with `unref()` and left to exit on its own. A one-shot worker that ends after a single `postMessage` needs no `terminate()` at all: it exits by itself. This bites hardest on the path you cannot test locally, because the abort only reproduces once the native module actually loads.

+- **Do:** Re-run plain `npx gitnexus analyze` — no `--embeddings` flag needed. A retained `embeddingCheckpoint` in the index metadata forces embedding generation for exactly the pending nodes regardless of flags, and clears once they succeed. `--drop-embeddings` abandons the pending nodes instead of retrying them; `--force` also discards the checkpoint (with a warning) and rebuilds without resuming it.
+- **Why:** A long analyze run against a flaky HTTP embedding endpoint tolerates bounded sub-batch failures instead of aborting the whole run: it deletes the affected nodes' embedding rows (so they hold zero rows, never a partial set) and records those nodes as pending in `embeddingCheckpoint`. `stats.embeddings` stays an honest, non-zero count of everything that did succeed, so this state never trips the "Embeddings vanished" Sign above — `embedding-checkpoint-pending` is the only reliable signal.

+## Ambiguous responses report the true match count (PR #2796, issue #2787)
+
+The MCP symbol resolver returns at most 20 candidate rows. Every ambiguous
+response used to take its count from that capped window, so a name with 92
+matches (`constructor`, in this repo's own index) reported 20. The same PR
+pinned the window with an `ORDER BY`, which turned that undercount from
+flaky into stable — and a stable wrong number reads as authoritative.
+
+Three consumer-visible changes follow:
+
+- **`impact`'s `totalCandidates` changed meaning.** It was the length of the
+  capped 20-row window; it is now the true `COUNT(*)` of matching symbols.
+  Callers using `totalCandidates === candidates.length` as a "not truncated"
+  proxy will now see the two diverge. This is a bug fix — the old number was
+  wrong — but it is still a value change on a published field.
+- **`totalCandidates` and `candidatesTruncated` are new on other tools.**
+  They now also appear on `context`, `trace`, the `explain` / `pdg_query`
+  block-anchor path, and on `rename` (which returns `context`'s ambiguous
+  payload verbatim). `candidatesTruncated: true` is present only when
+  `candidates[]` is shorter than `totalCandidates` — absent otherwise, never
+  `false`.
+- **The `message` template gained a `(showing M)` suffix.** It follows the
+  total — `Found 92 symbols matching 'constructor' (showing 20). …` — and
+  appears only when the returned window is smaller than the total. `impact`
+  uses the longer `(showing M of N)` form.
+
+### Do I need to migrate?
+
+**Only if you read `totalCandidates` or parse `message`.** The last two
+changes are purely additive — no field was removed or renamed and
+`candidates[]` keeps its shape — so PR #888's "no existing field has changed.
+No migration required for `context` callers" still holds for `context`.
+
+- Reading `totalCandidates` on `impact`: it is a true total now. Detect a
+  shortened window with `candidatesTruncated` (or `totalCandidates >
+  candidates.length`) rather than by comparing it to an array length.
+- Parsing `message` for a count: the total is still the first number, but a
+  `(showing M)` parenthetical may now follow it. Prefer the structured
+  `totalCandidates` field over the string.
+
+### What happens on re-index?
+
+Nothing — this is an MCP-surface change only. The graph schema, indexer,
+and stored data are untouched.

-**Important:** If you already had embeddings, **always** pass `--embeddings` on later analyzes, or they can be dropped. See `stats.embeddings` in `.gitnexus/gitnexus.json` (or its legacy `meta.json` mirror; 0 means none).
+**Important:** If you already had embeddings, a plain `npx gitnexus analyze` **preserves** them (Non-negotiable 5 in [GUARDRAILS.md](GUARDRAILS.md)) — pass `--embeddings` when you also want vectors generated for new or changed nodes, and `--drop-embeddings` only for a deliberate wipe. See `stats.embeddings` in `.gitnexus/gitnexus.json` (or its legacy `meta.json` mirror; 0 means none) — but that figure isn't always freshly measured: if a run's embedding-count query can't answer, it carries the previous run's number forward instead of writing a wrong zero. For a certified read, check `capabilities.vectorSearch.status` instead — it reads `unavailable` (never a stale count) whenever GitNexus can't vouch for the live vector index.
+
+**Partial embedding index (analyze exits 0, but some nodes never got embedded):** A long run against a flaky embedding endpoint can finish successfully while a bounded number of sub-batches still fail. Affected nodes are dropped to zero rows (never left half-written) and recorded as a pending `embeddingCheckpoint`; `npx gitnexus status` then reports `incompleteReasons: ["embedding-checkpoint-pending"]`. Recovery is a plain:
+
+```bash
+npx gitnexus analyze
+```
+
+No `--embeddings` flag needed — a retained checkpoint forces embedding generation for the pending nodes regardless of flags, and clears once they succeed. `--drop-embeddings` abandons the pending nodes instead of retrying them; `--force` also discards the checkpoint (with a warning) and rebuilds without resuming it.
 
 **Large repos:** Analyze may skip or limit embedding work when node counts are very high; watch CLI output.

 Notes: `offset` ≥ `total` returns an empty page (with `total` still reported). Out-of-range or malformed `limit`/`offset` (non-integer, `limit` outside `[1, 200]`, `offset < 0`) are rejected with a clear error — `limit` above the max is rejected, not silently capped. The order is deterministic (lower-cased name, then path), so paging never skips or duplicates an entry while the registry is unchanged.
 
+### Inline staleness signal (`query` / `context` / `impact` / `cypher`)
+
+These four hot read tools attach a non-blocking `staleness` field to their response when the index is behind the checkout's current HEAD — the same `{ commitsBehind, hint }` shape `list_repos` already reports — so a direct tool call surfaces a behind-HEAD index without a separate `list_repos` call:
+
+```jsonc
+{ /* …the tool's normal result… */
+  "staleness": { "commitsBehind": 3, "hint": "⚠️ Index is 3 commits behind HEAD. Run analyze tool to update." }
+}
+```
+
+The field is **absent when the index is current** (or when the freshness check can't run), so its presence is the signal. It is only ever added to object results — raw-array `cypher` output and error envelopes are returned unchanged. `@group`-targeted calls do not carry it (multi-repo staleness is ill-defined). When you see it, the graph may be behind the working tree — re-run `analyze` before trusting blast-radius or dependence answers.
+
 ### Taint findings (`explain`)
 
 `explain` returns taint findings recorded by `gitnexus analyze --pdg` — intra-procedural `TAINTED` edges plus cross-function `TAINT_PATH` hops where the interprocedural taint phase found a function-level source→sink chain. Each finding includes a sink category (command-injection, code-injection, path-traversal, sql-injection, xss), source/sink lines, and the ordered hop path with the variable carried on each hop.

+> **Experimental — not supported for production indexes.** The Icebug engine is a research path for #2337. It carries no stability guarantee, may change or be removed without a major version, and partitions differently from the default, so switching engines changes community IDs and any generated context keyed on them. Reindex with `graphology` before relying on the output.
+
+Community detection uses the bundled Graphology Leiden implementation by default. To try the #2337 Icebug path without changing default analyze behavior, install the optional native package alongside GitNexus and set the engine:
 
 ```bash
+npm i @ladybugmem/icebug
 GITNEXUS_COMMUNITY_ENGINE=icebug npx gitnexus analyze
 ```
 
-Supported values are `graphology`, `icebug`, and `auto`. The Icebug path is an experimental probe: GitNexus does not bundle an Icebug native package yet, and if a separately resolvable module is unavailable or its API does not match the expected `Graph.fromCSR` / `ParallelLeidenView` shape, analyze falls back to Graphology and reports the fallback in progress output. Today `auto` is behaviorally identical to `icebug`: both try Icebug and fall back to Graphology, while `graphology` skips the Icebug probe entirely.
+Supported values are `graphology`, `icebug`, and `auto`. Today `auto` is behaviorally identical to `icebug`: both try Icebug and fall back to Graphology, while `graphology` skips Icebug entirely.
+
+Icebug is **not** a declared dependency — its prebuilds link against system Arrow 24 (`libarrow.so.2400`), OpenMP, and glibc ≥ 2.38, none of which GitNexus can assume. Analyze falls back to Graphology and reports the reason in progress output when the module is missing, fails to load, or predates the `setNumberOfThreads` / `setSeed` controls that reproducible community IDs require (present at [icebug-nodejs](https://github.com/Ladybug-Memory/icebug-nodejs) HEAD, absent from the published 12.8.0 tarball — so the fallback is what you will see today). The engine is pinned to `threads: 1`, `randomize: false` for determinism.
+
+Note that the bundled Graphology path is no longer the slow option it once was: #2337 removed an accidental O(communities × N) copy in the vendored Leiden. On a synthetic 200k-node / 800k-edge benchmark graph it went from exceeding the 60s timeout to finishing in ~15s. Real projections vary with their degree distribution, so treat that as a direction, not a guarantee.

+## JVM Package Sibling Injection
+
+Java and Kotlin files in the same package receive implicit sibling class bindings
+to resolve same-package references. By default, GitNexus injects at most 200
+siblings per module scope, nearest first by path. Set
+`GITNEXUS_MAX_INJECTED_SIBLINGS=0` to remove that per-file limit; this can
+substantially increase indexing work for large packages.
+
+```bash
+export GITNEXUS_MAX_INJECTED_SIBLINGS=200
+gitnexus analyze .
+```
+
+When the limit truncates a file's sibling set, that file is marked
+visibility-incomplete: same-package references still resolve through the
+injected siblings, but wildcard-import attribution (used by the Spring
+bean/DI/config passes) is disabled for it rather than resolved against a
+partial view. Analyze logs a `sibling injection truncated` warning naming how
+many files were affected.
+
+Packages with more than 500 files are a separate, fixed limit: they are skipped
+entirely (logged as `skipping package with N files`) and every file in them is
+marked visibility-incomplete. `GITNEXUS_MAX_INJECTED_SIBLINGS` does not lift
+that skip — including at `0`.

 Some optional language grammars (Dart, Proto, Swift, Kotlin) require native compilation. If they fail, GitNexus still works — those languages will be skipped. To skip them intentionally (no C++ toolchain needed), set `GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1` before installing.

 ### Analysis runs out of memory
 
+Memory management is automatic: `analyze` sizes its heap to the machine
+(always below physical RAM), caps each parse worker, and — rather than
+grinding into a GC death spiral or crash — stops early with a message telling
+you the one thing to do. Repeated
+`Replacement worker did not report ready within 5000ms` warnings on a large
+repository are part of the same picture: memory pressure starving healthy
+workers, not a worker bug (#2649).
+
+If analyze says the repository doesn't fit, do what the message says:
+
+- **The machine has more memory to give** (a `NODE_OPTIONS`
+  `--max-old-space-size` pin from your environment is holding analyze back):
+  re-run without the pin — no flags needed.
+- **The machine is the ceiling**: shrink the scope (exclude generated or
+  vendored directories, below) or use a machine with more RAM.
+
+Escape hatches (`GITNEXUS_MEMORY=off` to decline the autopilot,
+`GITNEXUS_WORKER_HEAP_MB` to size workers yourself) are listed in the
+environment-variable table below —
+most users never need them.
+
 For very large repositories:

 # Increase Node.js heap size

+# repo's own .gitnexusignore or needing push/commit access to it. GitNexus
+# reads the same sources `git` itself does: core.excludesFile (all repos)
+# and $GIT_DIR/info/exclude (this repo only, untracked). A repo's own
+# .gitignore/.gitnexusignore can still override either with a `!pattern`

+### Scope-resolution property-key dispatch cap
+
+During scope resolution GitNexus synthesizes CALLS edges through *property-key
+dispatch* — call sites like `hooks.emitScopeCaptures()` where a property key is
+registered by multiple definitions across the codebase. To keep this fan-in
+bounded, each property key is capped at **32 registrations**: a key registered
+by more than 32 distinct functions is skipped entirely (no CALLS are synthesized
+through it), and the dropped key names are surfaced in the analyze log for
+operator visibility. The cap is calibrated at 2× this repo's own provider table
+(16 legitimate registrations, one per language provider).
+
+| Variable                                | Default | Effect                                                                                                                                                                                                                                                                                                                |

+# resolution reruns.

+
+### Scope-resolution dispatch-target cap
+
+During scope resolution GitNexus resolves calls that flow through *callable
+values* — function/method references bound to variables, passed as arguments,
+or stored in maps/tables. To keep that inclusion-based resolution finite, each
+callable site is capped at **32 dispatch targets**. When a site gathers more
+candidates than the cap it is treated as **overflowed** and *all* of its call
+edges are dropped — a cliff, not a tail, so a repository with a legitimately
+wide dispatch table (a single callable site resolving to 33+ targets) loses
+that site's whole call chain. In that case `analyze` logs
+`callable-value-flow: candidate set exceeded the cap; no partial CALLS emitted`
+alongside a warning carrying the language, the overflowing context, the
+candidate count, and the cap (32).
+
+Raise the cap for such repositories:
+
+| Variable                              | Default | Effect                                                                                                                                                                                                                                                                                                              |

+/**
+ * Build-free throughput + identity bench for `buildGraphTargetIndex`, the
+ * callable-value-flow target index (issue #2693).
+ *
+ * #2693 widened this function's gate: before it, only Function/Method/
+ * Constructor defs were considered; now VALUE bindings (Const/Property/Static/
+ * Variable) are considered too, because a closure bound to a name declares as a
+ * value but emits a callable graph node (#2687). Value bindings usually
+ * OUTNUMBER callables in real source, so the widening puts the hot loop's cost
+ * on a much larger def population — this bench exists to keep that honest.
+ *
+ * Value bindings are joined to their callable node POSITIONALLY
+ * (`file\0line\0name`); they never run the `resolveDefGraphId` key chain,
+ * whose label-agnostic `simpleKey` fallback would alias a binding onto any
+ * same-named callable in the file.
+ *
+ * For a synthetic corpus at two scales it reports:
+ *   - elapsed_ms_small / elapsed_ms_large (fastest of REPS, see `fastest`) + a scaling ratio
+ *     `(t_large/t_small)/(LARGE/SMALL)`: ~1.0 linear, ~3.x quadratic;
+ *   - `callable_only_ms_large`, the same corpus with the PRE-#2693 def
+ *     population, so the cost the widening actually added stays visible as
+ *     `widening_overhead` rather than being folded into one opaque number;
+ *   - an order-independent sha256 fingerprint over every (defNodeId → graphId)
+ *     pair the index resolves, as the correctness gate. A fingerprint change
+ *     means the set of callable-value targets moved — that is a behaviour
+ *     change, never a performance one.
+ *
+ * Build-free: imports the `.ts` hotpaths through tsx
+ * (`node --import tsx bench/callable-value-flow/measure.mjs`). Static `.ts`
+ * imports work; a top-level `await import()` breaks tsx's lexer.
+ *
+ * Without args: prints one JSON object per scale plus the summary.
+ * With `--check`: asserts the fingerprint == the committed baseline AND both
+ * the scaling ratio and the widening overhead are within their recorded
+ * budgets; exits non-zero on drift/regression.

(4) A member declared at BOTH the namespace level and in an inline child, selected apart by argument type, pinning both collection sources by nodeId.

The band this file previously claimed — 0.93-1.21 — did not reproduce and was an artifact: the small arm then measured ~1.7 ms, small enough that timer granularity and JIT warm-up, not scaling, set the number (the same ten-run sweep of that bench spanned 1.11-1.40). CALLS_PER_FILE is now sized so the small arm lands at ~14 ms; that halves the unloaded spread (0.30 -> 0.16) and costs ~2.0 s of wall time for the whole bench. The residual above 1.0 is real and not a defect: at LARGE the index and corpus are 4x the working set, so per-call-site locality is worse (~85 ns/site vs ~63 ns) while the algorithm stays linear. TRIAGE: a scaling failure is a TIMING signal — RE-RUN IT on an idle machine before investigating. Runner contention dominates everything above: pinned to 2 CPUs against 2 spinners the identical binary produced 1.16-2.18, i.e. a spurious FAIL, and the sibling bench/callable-value-flow drifts out of its own documented band the same way. The fingerprint arm is the opposite — it is deterministic; a re-run never changes it and must never be used to wish it away. Floor check: a per-call-site workspace rescan reintroduced ONLY on the receiver-bucket-absent path (the most plausible way #2788 returns) measures 4.538 at these same 400/1600 file scales — 812x slower on the small arm, 2850x on the large — while leaving the fingerprint byte-identical. The old always-hits corpus scored that same patch 1.279 and printed PASS. Resolution is timed alone; the fingerprint's outcome strings are built in a separate untimed pass because their allocation cost grows with the corpus and would otherwise show up as scaling."

+/**
+ * Build-free scaling + identity bench for `resolveCppQualifiedNamespaceMember`,
+ * the C++ qualified `ns::member()` receiver resolver (issue #2788).
+ *
+ * Before #2788 this function re-scanned EVERY parsed file — rebuilding a
+ * per-file `scopesById` map each time — once per qualified call site, so the
+ * scope-resolution emit phase cost O(callsites × scopes). On a 1,473-file C++
+ * repo that was 25.3 min of a 33-min analyze, with 75% of total self-time in
+ * this one function. It is the same bug #1990 had already fixed in the sibling
+ * ADL path (`pickCppAdlCandidates` → `AdlCandidateIndex`). #1990 DID ship a
+ * scaling gate for that path — `test/integration/cpp-adl-benchmark.test.ts`,
+ * which asserts `emitRatio < fileRatio^1.5` — but it could never have caught
+ * this one, for two independent reasons: its corpus asserts
+ * `callsResolved === 0`, i.e. it generates only UNRESOLVED ADL sites, so it
+ * never drives the qualified-receiver path at all; and it is
+ * `describe.skipIf(!BENCH_ENABLED)` while the single CI step that sets
+ * `GITNEXUS_BENCH=1` names its test files explicitly and, until this PR wired
+ * it in, listed neither C++ bench — so it had never executed in CI. Even now
+ * that it runs, the `callsResolved === 0` half stands: it still cannot reach
+ * this path. Hence this bench, in an always-on step: a per-call-site workspace
+ * scan must not be reintroduced silently.
+ *
+ * For a synthetic corpus at two scales it reports:
+ *   - `elapsed_ms` per scale (fastest of REPS, see `fastest`) for resolving
+ *     every call site once, INCLUDING the one-time index build — that build is
+ *     the work the per-site scan was traded for, so hiding it would let an
+ *     index that is itself quadratic pass;
+ *   - a scaling ratio `(t_large/t_small)/(LARGE/SMALL)`: ~1.0 linear,
+ *     ~4.x quadratic at this scale gap;
+ *   - a sha256 fingerprint over every `receiver::member(callsite) → outcome`
+ *     the corpus resolves, as the correctness gate. A fingerprint change means
+ *     qualified lookup started resolving different symbols — a behaviour
+ *     change, never a performance one.
+ *
+ * A gate only covers the code path its corpus drives. Two properties below are
+ * therefore load-bearing and must not be "simplified" away:
+ *
+ *   1. **The receiver mix is production-shaped: ~1 in 5 receivers names a
+ *      namespace, the other ~4 name nothing.** Case 1.5 in
+ *      `scope-resolution/passes/receiver-bound-calls.ts` is reached by EVERY
+ *      plain-identifier receiver call — `obj.size()`, `Widget::make()`,
+ *      `buf.data()` — so in real source the overwhelming majority of calls into
+ *      this resolver are receiver MISSES, not member misses inside a resolved
+ *      receiver. An earlier revision of this bench drew every receiver from
+ *      `ns_${…}`, i.e. always a namespace the corpus declared, so the receiver
+ *      lookup never missed. Measured consequence: a "defensive full rescan when
+ *      the receiver bucket is absent" regression — the single most plausible
+ *      way this bug returns — scored 1.332 against the 1.8 budget and printed
+ *      PASS, while costing 507× on a production-shaped corpus.
+ *   2. **The corpus contains every structural shape whose loss the fingerprint
+ *      is supposed to catch** (see `buildCorpus`), including a batch of sites
+ *      that pass a real `Callsite`. Without those, `narrowOverloadCandidates` /
+ *      `cppConversionRank` / `isOverloadAmbiguousAfterNormalization` are not in
+ *      the fingerprinted surface at all, and behaviour-only regressions there
+ *      re-fingerprint byte-identically.
+ *
+ * Build-free: imports the `.ts` hotpath through tsx
+ * (`node --import tsx bench/cpp-qualified-ns/measure.mjs`).
+ *
+ * Without args: prints the JSON report.
+ * With `--check`: asserts the fingerprint == the committed baseline AND the
+ * scaling ratio is within budget; exits non-zero on drift/regression.

+ *     `gatherQualifiedNsMember`'s `visited` dedup, without which the one

+
+## Receiver ORIGIN — three quarters of the hedge was the program boundary
+
+The drop count was measuring two different things and reporting both as
+uncertainty. Dumping all 102 call drops with source context settles it:
+
+| Origin       | Count  | Is anything lost?                                                                                                                                                                        |
+| ------------ | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `external`   | **44** | **No.** `System.out.println`, `fetch(...)`, `os.environ.setdefault`, `document.body.appendChild`, `.stream()`. The callee is not in the graph — there is no node an edge could point at. |
+| `in-program` | 36     | Yes in principle — but see below.                                                                                                                                                        |
+| `unknown`    | 22     | Yes. Casts, ternaries, `globalThis.x ??= []`, and everything the classifier will not guess about.                                                                                        |
+
+> **These numbers moved once, in review, and the movement is the point.** They
+> were first measured as 76 / 20 / 6, when `external` was the FALLTHROUGH: any
+> base whose type did not resolve was called external. Review reproduced two
+> triggers where that published `epistemic: 'exact'` over a real in-program loss
+> — a Go pointer receiver (`*Host`, whose lookup was missing the decoration
+> stripper) and any base with no type binding at all, including this branch's own
+> `droppedCall(svc)` fixture. `external` is now a POSITIVE determination via
+> `LanguageProvider.isBuiltInName`, and everything unproven is `unknown`, which
+> still hedges. So `external` fell 76 -> 44 and the difference went to
+> `in-program` (+16, the drops that really were ours) and `unknown` (+16, the
+> drops we decline to characterize). Total call drops is unchanged at 102 —
+> this is re-bucketing, not resolution.
+>
+> A controlled A/B over the Java built-in set (off vs on, same tree) reads
+> 7/36/59 vs 44/36/22: `in-program` is byte-identical across the toggle, so
+> naming built-ins reclassified nothing the index can demonstrate is ours.
+
+**A compiler resolves `System.out.println` against the JDK.** Lacking the JDK,
+the honest statement is _"this call leaves the analyzed program"_ — not _"this
+analysis is incomplete"_. Those are different epistemic states, and collapsing
+them is what made `impact` report a lower bound on essentially every real
+codebase, which is what teaches readers to ignore the signal.
+
+`ResolutionOutcome.receiverOrigin` now records which one applies, and
+`summarizeUnresolvedReceivers` skips `external`. `unknown` still counts —
+assuming a completeness we cannot demonstrate is the unsafe direction.
+
+### How origin is decided
+
+By the receiver base's **declared type**, not its name. A first cut asked
+whether the base was a local, which marked `inputs.stream()` in-program:
+`inputs` is a local, but its type `List<String>` is JDK, so the target is
+external. Asking whether the base's _type_ is one this index contains moved 28
+sites to the correct bucket.
+
+### What the remaining in-program drops actually are
+
+Mostly **not** product defects. `user.Address.Save()` resolves cleanly in
+isolation — the `csharp-deep-field-chain` fixture alone emits both expected
+edges with **zero** drops. It drops in the count arm only because the corpus is
+~200 independent mini-projects in one directory and **55 files define
+`Address`**, so the resolver correctly declines on ambiguity rather than picking
+one. That is right behaviour measured on an unrepresentative corpus.
+
+The genuinely untypeable population is the `unknown` bucket — and those are the real
+targets for type resolution, because a cast _gives_ you the type
+(`((Box<String>) obj).open()`) and a ternary needs a join of its branch types.
+They were previously invisible under the stdlib calls the old fallthrough swept
+into `external`.
+
+`callDropsByOrigin` is now part of the gated projection, so this split cannot
+drift silently.
+
+---
+
+## Phantom callee read sites — a duplicate-edge bug the U8 test missed
+
+Go's `@reference.read` pattern matches **every** `selector_expression`, with no
+call-position exclusion. So `h.dep.Work()` minted **three** reference sites:
+
+| site | kind   | name   | what it is                                                    |
+| ---- | ------ | ------ | ------------------------------------------------------------- |
+| S1   | `call` | `Work` | the member call                                               |
+| S2   | `read` | `Work` | **phantom** — the callee `h.dep.Work`, already captured by S1 |
+| S3   | `read` | `dep`  | the genuine field read                                        |
+
+S2 resolved through `findOwnedMember`, which prefers methods over fields, and
+emitted an `ACCESSES` edge to the **method** duplicating S1's `CALLS` edge at the
+same position.
+
+**The U8 assertion passed by accident.** It asserted `RunSamePackage → Work` was
+absent from `ACCESSES`, and it was — but only because that row has a _pointer_
+receiver whose text-cascade head lookup failed for an unrelated reason. The
+value-receiver twin was emitting the bad edge the whole time:
+
+```
+ACCESSES  RunFromValueReceiver -> DoWork:Method     <- phantom, shipped
+ACCESSES  RunLocal             -> DoWork:Method     <- phantom, shipped
+```
+
+First fix, at capture: drop the match outright, on the rule _"a selector in
+function position is never a read."_ **That rule is false, and review caught
+it.** In Go a func-typed struct field IS read and then called indirectly —
+`h.dep.Work()` where `Work func() error` — and `isCalleeOfMemberCall` cannot
+tell a method from a func-valued field, because the AST shape is identical.
+Dropping at capture therefore deleted the only `ACCESSES` evidence for callback
+structs, hook structs and hand-rolled mocks (`mock.DoFunc`, `opts.OnEvent`).
+
+Second fix, and the one that shipped: **split the decision across the two layers
+that each hold half of it.** Capture records the POSITION as a fact
+(`@reference.callee-position` → `ReferenceSite.inCalleePosition`) — only the AST
+knows it, and it is gone by resolution time. Emit makes the DECISION from the
+resolved target's kind — only resolution knows whether the tail is a method or a
+field, and it may be declared in another package. Neither layer can answer alone.
+The suppression is language-neutral in `graph-bridge/edges.ts` and keys on the
+canonical `CALL_TARGET_TYPES`, so `Macro` and `Delegate` targets are covered too.
+
+A method _value_ (`f := h.dep.Work`) is not in function position and is
+untouched. The assertion is backed by an exact-set check over the whole fixture —
+now carrying target KINDS, so it catches both a new phantom and a deleted
+genuine read.
+
+### What the numbers say
+
+- `callDrops` **unchanged at 102** — no call was lost, in either fix.
+- `read` drops went **27 → 22** under the capture-time drop, then **22 → 27**
+  again once the marker replaced it. The round trip is the finding: those five
+  sites are genuine field reads, and the first fix was scoring their deletion as
+  an improvement.
+- `totalDropsAllKinds` **124 → 129**, the same five sites.
+- One drop reclassified `chain-field` → `chain-unwrap`. The phantom and the real
+  call share a site key, so the phantom's field-shaped chain was previously the
+  one recorded. The census now describes the actual dropped call.
+
+Caught by three review agents dispatched at the A1 regression; the phantom was
+the mechanism, not the global-normalization story the first revert note asserted.
+The func-field regression it introduced was then caught by two more, on the
+tri-review of #2782 — which is the argument for the exact-set-with-kinds
+assertion over the targeted one that passed by accident the first time.
+
+---
+
+## U9 (part 2) — no drop ratchet is needed; the gate is already stronger
+
+The plan's R10 set a ZERO supported-shape drop target, and review correctly
+found that it contradicts R12: a site whose normalized name matches more than
+one class MUST decline, a decline records a drop, and simple names collide
+routinely in large Go and Java codebases. The proposed fix was a ratchet — the
+count may not rise above the value measured after the last unit.
+
+Neither is needed. `measure.mjs --check` already asserts **exact match** against
+the committed baseline, which is strictly stronger than a ratchet: the count
+cannot rise _or_ fall without a deliberate `--update-baseline`, and that path
+prints an instruction to explain the movement in the commit message. A ratchet
+would be a weakening.
+
+So R10 as written (zero) was wrong, and the ratchet proposed to repair it is
+redundant. The existing gate stands, now also covering `callDropsByShape` since
+the shape census joined the gated projection.
+
+**Deferred and NOT done: the `impact` risk-cutoff recalibration.** Review flagged
+that added edges push symbols toward the absolute cutoffs (`directCount >= 30`,
+`impacted.length >= 200`), so edits read HIGHER risk without being more
+dangerous, and agents warning on HIGH/CRITICAL escalate more often. That is real,
+but measuring it honestly needs a before/after risk distribution over a corpus
+large enough for those thresholds to bind — the committed fixtures are nowhere
+near 200 impacted symbols. Recording it as owed rather than inventing a number
+from fixtures that cannot exercise the cutoffs.
+
+---
+
+## U6 — the depth cap does NOT limit resolution. Measured, not raised.
+
+The premise was that a chain deeper than `MAX_CHAIN_DEPTH` (3) is discarded
+whole rather than truncated, so a 4-hop builder chain "contributes nothing at
+all". The first half is true; the second is not.
+
+`fourHopChain` was added to the TypeScript corpus as a declared extra
+specifically to make the question answerable — without a chain longer than the
+cap, raising the cap measures nothing:
+
+```ts
+root.getSvc().getUser().address.getCity().save();
+//   ^step1     ^step2   ^step3   ^step4   receiver of `save` = 4 steps
+```
+
+| Cap | Chain minted?                                        | Cell state   |
+| --- | ---------------------------------------------------- | ------------ |
+| 3   | **none** (confirmed by probing the emitter directly) | **RESOLVES** |
+| 4   | `2\|root\|cgetSvc\|cgetUser\|faddress\|cgetCity`     | RESOLVES     |
+
+The site resolves at BOTH depths. At 3 it resolves through the text cascade,
+which owns the fallback path and runs to its own
+`COMPOUND_RECEIVER_MAX_DEPTH` of 8.
+
+**So the cap bounds which chains are typed structurally, not which calls
+resolve.** Raising it moves work from the cascade to the fold without changing a
+single edge — measured across the whole matrix: totals identical at 3 and 4,
+`callDrops` 102 at both.
+
+Left at 3. The fixture is committed so the next person to reach for this number
+inherits the measurement instead of the intuition.
+
+What DID need fixing: `unwrapTransparentReceiver` shared `MAX_CHAIN_DEPTH` as
+its iteration bound. The two answer unrelated questions — how many chain hops do
+we type, versus how many redundant parens might someone write — so raising the
+chain cap would have silently widened the paren peel as a side effect. That
+coupling got worse when the await/subscript work added a peel call at loop
+entry. Now `MAX_TRANSPARENT_WRAPPER_DEPTH`, its own constant.
+
+---
+
+## U9 — the epistemic hedge has TWO producers, and only one is a defect
+
+`impact` reports `epistemic: 'lower-bound'` for two independent reasons that were
+previously indistinguishable in the output:
+
+| Cause              | Unit       | What it means                                                                                                                                             | Is it a defect?                                                                                                                       |
+| ------------------ | ---------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------- |
+| `receiverTyping`   | call sites | Call sites dropped because the analyzer could not type the receiver                                                                                       | **Yes** — a resolver gap. This is the population this whole series targets.                                                           |
+| `dispatchBoundary` | symbols    | The symbol sits behind an interface with real consumers or 2+ implementations; the number is the implementations plus interface-level consumers behind it | **No** — callers binding through DI or dynamic dispatch are genuinely untraceable statically. A compiler refuses here too.            |
+| `externalBoundary` | call sites | The call left the indexed program (`System.out.println`, `fetch(...)`)                                                                                    | **No**, and not even a shortfall — there is no in-graph node an edge could have reached. An `epistemic: 'exact'` result can carry it. |
+
+Both collapsed into one enum plus prose, so a consumer — especially a coding
+agent gating its own edits on the result — could tell THAT a count was short but
+not WHY, and could not branch on the difference. Worse, it made "the hedge should
+stop appearing" unfalsifiable: with no way to see which producer fired, there was
+no way to check whether fixing receiver typing had done anything.
+
+`impact` and `context` now carry a structured `causes: { receiverTyping,
+dispatchBoundary, externalBoundary }` alongside the prose. Every field counts
+MISSING THINGS, never notes: there is one note per symbol name (and one per
+boundary node) but each reports N of something, so counting notes published `1`
+next to prose reading "2 call sites", and a consumer branching on the number
+would have read a different magnitude than the human reading the text. The same
+rule applies to `dispatchBoundary`, which counts the implementations plus
+interface-level consumers behind the boundary rather than the boundary sentences
+— one sentence can describe an interface with 40 implementations. Its unit is
+SYMBOLS rather than call sites because per-site multiplicity is not retained on
+those edges (consumers are counted `DISTINCT`, and
+`collapseMemberCallsByCallerTarget` languages emit one CALLS edge per
+caller/target pair); the units are stated per field on `EpistemicCauses` so a
+consumer knows which it is holding.
+
+**Only the `receiverTyping` producer is addressed by this series.** The dispatch
+boundary is untouched and will keep firing for interface-dispatched symbols —
+which is correct. Any claim that the hedge has "stopped appearing" has to be read
+per-producer, and that is now possible.
+
+Measured on the #2766 reproduction: `WithTx` went from `impactedCount: 0` with a
+`lower-bound` hedge to `impactedCount: 1` with `epistemic: exact`. The hedge is
+gone there because its cause is gone, not because it was suppressed.
+
+---
+
+## U10 — recorded drops, censused by receiver shape
+
+`ResolutionOutcome`'s suppressed variant now carries `receiverShape`, set by the
+emitting case from the site's ENCODED CHAIN — the compact string the capture
+emitters mint by walking the real AST. Never re-derived from the source line:
+doing that would mean regex-classifying the number that gates this work, the
+same textual-shape dispatch the structural-receiver line exists to remove.
+Diagnostic only, so the persisted `RepoMeta.unresolvedReceiverMembers` artifact
+is unchanged.
+
+Census of the call drops on the committed fixture corpus, **as measured at U10**
+— it predates the phantom-read fix documented above, which reclassified one drop
+`chain-field` → `chain-unwrap`. `callDropsByShape` in `baseline.json` is current:
+
+| Shape                                                         | Count | Share |
+| ------------------------------------------------------------- | ----- | ----- |
+| `chain-field` — every step a field (`h.repo.save()`)          | 60    | 59%   |
+| `chain-call` — every step a call (`svc.getUser().save()`)     | 27    | 27%   |
+| `no-chain` — no chain minted; the walk found no nameable base | 12    | 12%   |
+| `chain-mixed` — interleaved (`svc.getUser().addr.save()`)     | 2     | 2%    |
+
+Two decisions come out of it.
+
+**The `.java` bucket is not one defect.** Its 49 call drops split 30 field-chain
+/ 14 call-chain / 5 no-chain, so the open question of whether Java's largest-
+single-bucket status hides a single cause is answered: it does not. It is the
+same population as everywhere else, just more of it.
+
+**Field-receiver chains are where the remaining value is.** At 59% of the U10
+census they dominate, and they are precisely the shape U1 fixed for Go. The same
+defect class in java, csharp, cpp, php, py and rust is the largest addressable
+population the count arm can see. (This paragraph used to quote a per-extension ×
+per-shape split from the U10 run. `baseline.json` carries `callDropsByExtension`
+and `callDropsByShape` but not their cross-product, so that split has to be
+re-derived from a fresh run rather than read off the committed baseline.)
+
+**What this census CANNOT justify.** Await-wrapped and subscript receivers barely
+appear, because the committed fixture corpus contains almost no such sites — not
+because they are rare in real code. At U10 `indexElement` was a gap in every
+language in the shape arm, so U5's population was real but structurally invisible
+to the count arm. (It no longer is uniform — the subscript route resolves in
+several languages now; read the current per-language state from `indexElement` in
+`baseline.json`, not from this paragraph.) The durable point: any decision to fund
+or drop U4 and U5 has to be read off the SHAPE arm, because reading it off this
+census confuses "absent from these fixtures" with "does not happen".
+
+## U2 — shape matrix expanded to a canonical axis
+
+The shape arm was three languages with an ad-hoc shape list each. It is now a
+**canonical 10-shape axis** (`SHAPE_IDS`) that every language must answer for,
+with two states added so a hole cannot masquerade as a measurement:
+
+- `N/A` — the grammar does not admit this spelling. **A reason is required.** An
+  omitted cell and a genuinely inapplicable cell look identical in a diff
+  otherwise, which is how coverage rots.
+- `GRAMMAR-UNAVAILABLE` — the parser could not be loaded, so nothing was
+  measured. Neither passes nor fails the gate, and `drift` skips it on **both**
+  sides so the gate cannot fail for the environment it ran in. `tree-sitter-dart`,
+  `-kotlin` and `-swift` are vendored _optional_ grammars: absent when a run sets
+  `GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1`, and soft-failing when no vendored prebuild
+  matches the host (the set covers darwin/linux arm64+x64 and win32-arm64 — a
+  win32-x64 or musl host has none). **All 14 load on a glibc linux-x64 host, so
+  this state has no producer in the committed baseline** — it guards the
+  skip-flag and unsupported-host cases rather than a condition seen here.
+
+`assertMatrixComplete` throws when a language omits a cell, declares an unknown
+id, or writes an `N/A` with no reason. Languages may declare `extraShapeIds` for
+diagnostics the canonical axis cannot express (PHP's annotated/unannotated
+return-type pair, C++'s pointer/value base pair) — an extra must be declared, so
+it stays a deliberate diagnostic rather than a typo'd canonical id.
+
+**Vue and COBOL** are language-level `N/A` rows: their emitters never call
+`synthesizeReceiverChainCapture`, so there is nothing to measure — but the
+language axis now obeys the same no-omitted-cells rule as the shape axis.
+
+### What the first expanded run found
+
+Three results that redirected the plan they were built to serve. **Snapshot: the
+first U2 run, before any of the fixes below landed** — these cells state the
+problem, and several have since flipped (`baseline.json` is current):
+
+**Go — the root cause, isolated to one cell.** Three rows vary receiver
+decoration and field decoration independently:
+
+| Cell                    | Receiver    | Field       | State           |
+| ----------------------- | ----------- | ----------- | --------------- |
+| `fieldReceiverCall`     | value       | value       | RESOLVES        |
+| `decoratedFieldType`    | value       | **pointer** | RESOLVES        |
+| `decoratedReceiverBase` | **pointer** | value       | **VISIBLE-GAP** |
+
+Only the pointer _receiver_ fails. Go already normalizes field type bindings
+through `normalizeGoTypeName`, so the step lookup is sound and the defect is
+entirely the base — `synthesizeGoReceiverBinding` stores `typeNode.text` raw, so
+`func (h *Host)` binds `h` to the literal `*Host`, which
+`findClassBindingInScope` cannot resolve.
+
+**PHP — the sigil hypothesis is dead.** The two rows differ only in whether the
+called method declares a return type:
+
+| Cell                                          | Return type   | State         |
+| --------------------------------------------- | ------------- | ------------- |
+| `arrowCallChain` — `$svc->getUser()->save()`  | unannotated   | INVISIBLE-GAP |
+| `plainChain` — `$svc->getUserTyped()->save()` | **annotated** | **RESOLVES**  |
+
+Same chain, same `->`, same base. PHP chains resolve when the return type is
+declared; the `$` sigil is not involved. `decoratedFieldType` (`?User $repo`)
+also resolves, so PHP nullable field types already work.
+
+**C++ — the base already resolves, but `this->` field receivers do not.**
+`pointerArrowChain` and `valueDotChain` both RESOLVE, so a decorated C++ base is
+not a gap. But `this->repo.save()` and `this->repo->save()` are both
+INVISIBLE-GAP — a distinct defect, not a decoration one.
+
+**Rust — the decorated receiver is NOT a gap.** `&mut self` resolves, so Go is
+the only language whose method receiver decoration defeats the lookup. Rust's
+gap is the field: `Box<User>` is INVISIBLE-GAP.
+
+### The decoration cells, across all 14
+
+The rows U1 exists to fix. Everything else is a different defect. **Snapshot: as
+measured at U2, i.e. BEFORE U1 landed** — it is the statement of the problem, not
+of the current state. Go's `decoratedReceiverBase` and TypeScript's
+`decoratedFieldType` have since moved; `baseline.json` has the live cells.
+
+| Language                  | `decoratedReceiverBase`   | `decoratedFieldType`               |
+| ------------------------- | ------------------------- | ---------------------------------- |
+| go                        | **VISIBLE-GAP** (`*Host`) | RESOLVES                           |
+| rust                      | RESOLVES (`&mut self`)    | **INVISIBLE-GAP** (`Box<User>`)    |
+| typescript                | N/A                       | **INVISIBLE-GAP** (`User \| null`) |
+| csharp                    | N/A                       | **VISIBLE-GAP** (`User?`)          |
+| swift                     | N/A                       | **INVISIBLE-GAP** (`User?`)        |
+| cpp                       | N/A                       | **INVISIBLE-GAP** (`User*`)        |
+| python, php, kotlin, dart | N/A                       | RESOLVES                           |
+| java, c, javascript, ruby | N/A                       | N/A                                |
+
+So U1's measured scope is **Go's receiver base**, plus the field-type gap in
+**Rust, TypeScript, C#, Swift and C++** — and _not_ PHP, Python, Kotlin, Dart or
+Java, whose decoration handling already works or does not exist. Five of the
+seven hooks the plan speculatively listed were aimed at languages that need
+none; three languages that do need one were not on the list at all.
+
+### Other gaps this run surfaced, not in the plan
+
+- **Swift resolves almost nothing.** `plainChain`, `plainDeepChain`,
+  `optionalChain` and `nonNullAssert` are all INVISIBLE-GAP, while
+  `fieldReceiverCall` resolves. Chained receivers are essentially unsupported.
+- **Ruby chains are VISIBLE-GAPs** (`plainChain`, `plainDeepChain`,
+  `optionalChain`) and `fieldReceiverCall` on `@repo` is INVISIBLE.
+- **C++ `this->` field receivers** are INVISIBLE-GAP in both the value and
+  pointer form.
+- **C# has four gaps** beyond the field one: `optionalChain`, `nonNullAssert`,
+  `awaitParen`, `explicitTypeArgs`.
+- **Dart `await` already resolves** — the only language where `awaitParen` is
+  green, which makes it the reference for U4's unwrap direction.
+- **`indexElement` was INVISIBLE-GAP in all 14** at U2 — uniform, and exactly what
+  U5 targets. (Superseded: several languages resolve it now; see `baseline.json`.)
+
+### Coverage status
+
+All 14 languages measured, plus `vue` and `cobol` as language-level `N/A` rows.
+The cell tally recorded at U2 was 164 cells / 42 RESOLVES / 22 VISIBLE-GAP / 31
+INVISIBLE-GAP / 69 N/A / 0 GRAMMAR-UNAVAILABLE — a snapshot, superseded by every
+unit since (the axis also gained TypeScript's declared `fourHopChain` extra).
+Count the states off `baseline.json` rather than quoting this line.
+
+The **count arm did not move when the shape axis was expanded** — shape fixtures
+are built in temp directories and never touch the committed corpus, so expanding
+the shape axis moves the shape arm only.
+
+---
+
+> **Updated after U10** (structural receiver typing wired into Case 0). Three
+> TypeScript shapes flipped to `RESOLVES` — `svc?.getUser().save()`,
+> `svc!.getUser().save()`, `svc.getTyped<User>().save()` — and the call-drop
+> count did **not** move: 99 before, 99 after.
+>
+> That is the whole argument for the shape arm, now demonstrated rather than
+> predicted. The committed fixture corpus contains none of those three
+> spellings, so a gate reading only the drop count would have scored a working
+> change as "no improvement" and stopped the series. Nothing regressed: no edge
+> was lost and no new drop appeared.
+>
+> Two gaps remained open **at U10**, both genuine at the time:
+>
+> - `(await svc.getUserAsync()).save()` — `extractMixedChain` reached `await …`,
+>   which is not a chain node, so no chain was minted. It was a VISIBLE-GAP and is
+>   the call-kind fixture in the drop-recorder test.
+> - `repos[0].save()` — Case 0's punctuation gate never fired for a subscript
+>   receiver, so it was INVISIBLE.
+>
+> Both were subsequently closed for TypeScript by the `await`/`index` step kinds
+> (wire format v2) and by Case 0's third gate arm, which admits any site carrying
+> a minted chain regardless of receiver punctuation. Per-language state is in
+> `baseline.json` — `awaitParen` and `indexElement`.
+>
+> The tables below are the pre-U10 measurement, kept as the reference point.
+
+## U7 — the go/no-go gate: PASS
+
+A/B produced by reverting ONLY the fold wiring (`compound-receiver.ts` +
+`receiver-bound-calls.ts`) to the pre-U10 commit and rebuilding, so capture
+emission — and therefore the persisted bytes — is identical in both arms and the
+delta isolates the fold. Build + both caches wiped before every run (KTD4).
+
+| Metric                                   | Control     | Treatment   | Δ            | Threshold    | Verdict            |

+
+**The 35.2 B result confirms KTD7 by measurement rather than by assertion.** The
+48-byte threshold was set deliberately so the object encoding (~71 B predicted)
+fails and the compact string (~35 B predicted) passes. Measured: 35.2 B,
+including the JSON key and quotes. The encoding decision is now evidence-backed.
+
+**Peak RSS: the threshold is below this instrument's resolution, so it is
+reported as unresolvable rather than as a pass or a fail.** Three _independent_
+treatment runs with the code held constant gave 414.9 / 436.6 / 436.9 MB — a
+5.3% spread, wider than the ±2% being tested. (An earlier pair of 3-reps-in-one-
+process runs read 536 vs 551 MB and looked like a +2.77% regression; that was
+heap accumulating across reps, not growth.) Corroborating argument that no growth
+exists to find: the change persists 740 bytes across the entire corpus and the
+fold allocates nothing retained — it returns `SymbolDefinition`s the indexes
+already hold.
+
+**Fold hit-rate.** Chains are minted for 21 of 529 TypeScript reference sites
+(4.0%) — the field costs nothing on the 96% of sites with a bare-name receiver.
+On the shape corpus, all 5 chain-carrying shapes resolve, so the fold is not pure
+added cost on this population.
+
+**Not measured: a dedicated synthetic miss-dominant scaling corpus.** The plan
+asks for `scaling_ratio < 1.5` on one, on the grounds that a same-name corpus
+hits at `ownerChain[0]` and never exercises the MRO tail. Stated plainly so it is
+not mistaken for a silent pass. What bounds the cost instead: the fold runs with
+`fieldFallback: false`, so the O(fields × depth × names) path the threshold exists
+to police cannot execute at all, and the remaining work is at most
+`MAX_CHAIN_DEPTH` (3) map lookups per MRO ancestor per chained site, over a
+population of 21 sites. The wall-clock A/B above is the empirical check on that
+reasoning.
+
+Measured with `bench/receiver-resolution/measure.mjs` on `f87b2cbe`.
+
+Hygiene (a run without both steps is void — `analyze --force` clears neither cache,
+and the parse worker runs from `dist/`):
+
+```
+npm run build
+rm -rf .gitnexus/parse-cache .gitnexus/parsedfile-cache
+node --import tsx bench/receiver-resolution/measure.mjs --corpus test/fixtures/lang-resolution
+```
+
+Two consecutive runs were byte-identical, not merely within noise.
+
+## Count arm — `test/fixtures/lang-resolution`
+
+**Snapshot: the U7-era measurement (commit `f87b2cbe`), kept as the reference
+point for the A/B above.** The gate enforces `countArm` in `baseline.json`, which
+has moved since — read the live call-drop number, site-kind split, and
+per-extension breakdown from there.
+
+| Metric                           | Value at U7            |
+| -------------------------------- | ---------------------- |
+| **Call drops (the gate number)** | **99**                 |
+| Total drops, all site kinds      | 124                    |
+| Split by site kind               | `call: 99`, `read: 25` |
+
+Call drops by extension, at U7:
+
+| ext     | n   | ext    | n   | ext      | n   |
+| ------- | --- | ------ | --- | -------- | --- |
+| `.java` | 49  | `.py`  | 5   | `.rs`    | 3   |
+| `.cs`   | 8   | `.go`  | 5   | `.kt`    | 3   |
+| `.ts`   | 7   | `.cpp` | 5   | `.rb`    | 2   |
+| `.tsx`  | 6   | `.php` | 4   | `.js`    | 1   |
+|         |     |        |     | `.swift` | 1   |
+
+**Why the split matters (KTD6 defect 1, now measured).** About a fifth of the
+drops are property _reads_, not lost calls (25 of 124 at U7; `bySiteKind` in
+`baseline.json` is current). Case 0's recorder gates on the receiver's
+punctuation, not on what the reference is, so `d.source.kind` lands in the same
+bucket as a dropped method call. Gating on the unsplit total would have measured a
+population one fifth of which this work does not target.
+
+## Shape arm
+
+`RESOLVES` means an edge exists — **not** that it points at the right target. A
+name-keyed fallback onto a same-named member reads as `RESOLVES`, so a shape whose
+receiver has no well-defined type is not a usable control.
+
+**Snapshot: the pre-U10 measurement over three languages**, kept because it is the
+evidence that the shape arm moves when the count arm does not. Superseded twice —
+by U8's rollout table above and by the canonical shape axis in `baseline.json`.
+The three TypeScript rows marked as gaps here (`?.`, `!`, `<T>`) all resolve now.
+
+| Language   | Shape                                  | State at pre-U10  | siteKind |
+| ---------- | -------------------------------------- | ----------------- | -------- |
+| TypeScript | `svc.getUser().save()`                 | RESOLVES          | —        |
+| TypeScript | `svc.getUser().address.save()`         | RESOLVES          | —        |
+| TypeScript | `svc?.getUser().save()`                | **INVISIBLE-GAP** | —        |
+| TypeScript | `svc!.getUser().save()`                | VISIBLE-GAP       | `call`   |
+| TypeScript | `(await svc.getUserAsync()).save()`    | VISIBLE-GAP       | `call`   |
+| TypeScript | `svc.getTyped<User>().save()`          | **INVISIBLE-GAP** | —        |
+| TypeScript | `repos[0].save()`                      | **INVISIBLE-GAP** | —        |
+| PHP        | `$svc->getUser()->save()`              | VISIBLE-GAP       | `call`   |
+| PHP        | `$this->repo->save()` (typed property) | RESOLVES          | —        |
+| C++        | `svc->getUser()->save()`               | **INVISIBLE-GAP** | —        |
+| C++        | `svc2.getUser()->save()`               | RESOLVES          | —        |
+
+## Corrections to the plan, forced by measurement
+
+1. **Three target shapes are invisible, not one.** The plan records only
+   `repos[0].save()` as unrecorded. Measured, `svc?.getUser().save()` and
+   `svc.getTyped<User>().save()` are equally invisible: no edge and no drop.
+
+   This is the load-bearing correction. A gate built on the call-drop count alone
+   would move by **zero** when those three shapes are fixed, reading a working
+   change as "no improvement" — the same false-negative hazard the plan flags for
+   stale shards, arriving by a different route. Hence the shape arm: it is blind
+   to nothing, because it asks about edge presence rather than about a recorder
+   that has to have fired.
+
+2. **Invisibility is NOT a capture-layer gap.** Measured directly against
+   `emitTsScopeCaptures`, all five TypeScript shapes emit a full call match —
+   `@reference.call.member`, `@reference.name`, and crucially
+   `@reference.receiver`:
+
+   | Shape                         | `@reference.receiver`  |
+   | ----------------------------- | ---------------------- |
+   | `svc?.getUser().save()`       | `svc?.getUser()`       |
+   | `svc.getTyped<User>().save()` | `svc.getTyped<User>()` |
+   | `repos[0].save()`             | `repos[0]`             |
+
+   So a `ReferenceSite` exists for every one of them, and hanging a
+   `receiverChain` field on `ReferenceSite` is a viable carrier for all of them.
+   That was worth establishing before building on it.
+
+   The drop suppression is therefore downstream of capture. For `repos[0]` the
+   cause is known and matches the plan: the receiver has neither `.` nor `(`, so
+   Case 0's gate never fires. For `?.` and `<T>` the receiver text satisfies the
+   gate, so Case 0 _does_ run and one of two things happens — the site was marked
+   in `handledSites` by another case, or `resolveCompoundReceiverClass` returned a
+   class on which the member was then not found, leaving
+   `compoundReceiverUnresolved` false. Those are materially different defects and
+   which one applies is **not yet determined**; it is the first thing U10 has to
+   establish, since the second would mean the recorder under-reports by
+   mis-attribution rather than by a gate.
+
+   _(An earlier revision of this file asserted that these shapes produce no
+   reference site at all. That was inferred from edge-and-drop absence and is
+   disproven by the capture dump above.)_
+
+3. **KTD6 defect 2 overstates the PHP blindness.** The claim is that Case 0's
+   C-family punctuation test means PHP `->` receivers "never record a drop at
+   all". Measured, `$svc->getUser()->save()` _is_ recorded, because its receiver
+   text `$svc->getUser()` contains `(` and satisfies the gate. And the plan's own
+   example, `$this->repo->save()`, does not need recording — with a typed property
+   it resolves. The genuine PHP gap is the call chain, and it is already visible.
+
+4. **The C++ defect is the `->` base receiver specifically.** `svc->getUser()->save()`
+   is invisible while `svc2.getUser()->save()` resolves. Same chain, same `->save()`
+   tail — only the base differs. This is exactly why `cpp-chain-call/` has never
+   caught it: that fixture uses the value `.` form, which works.
+
+## Known blind spots
+
+Every count here is a lower bound on a known-biased population, and any later delta
+must be read against the same bias. Kept in sync with `KNOWN_BLIND` in
+`measure.mjs`, which prints these on every run.
+
+- Case 0 is reached by a receiver-TEXT punctuation test (`.` or `(`) **or** by a
+  minted receiver chain. A receiver spelled without that punctuation — a subscript
+  `repos[0]`, a PHP `->` / `::` property path — therefore reaches the recorder only
+  where its emitter mints a chain. Where no chain is minted, the call still
+  vanishes with the instrument blind to it.
+- A drop is recorded only while `compoundReceiverUnresolved` stays true. When the
+  cascade TYPES the receiver but then finds no member on it, the flag is false and
+  no drop is recorded even though no edge was emitted. So an absent drop is not
+  evidence a site resolved — the recorder can under-report by mis-attribution, not
+  only by a gate. (This is what moved PHP's `arrowCallChain` from VISIBLE-GAP to
+  INVISIBLE-GAP when its fixture parameter was typed; see U8 below.)
+- Retracted, and left here because it was quoted for several units: the earlier
+  claim that `?.` and explicit type arguments _"produce no reference site at all"_.
+  They do — the capture dump under "Corrections to the plan" §2 shows a full call
+  match with `@reference.receiver` for all three of `svc?.getUser()`,
+  `svc.getTyped<User>()` and `repos[0]`. The absence was of an EDGE and of a DROP,
+  never of a site.
+
+## U8 — per-language rollout
+
+Emission moved into one shared helper
+(`utils/receiver-chain-captures.ts`) and is wired into all 14 language
+emitters. The helper is language-free (R6): its call gate reads the
+`@reference.call.*` tag prefix, a vocabulary every language's `.scm` query
+shares, rather than a per-language tag list. It is self-gating — a non-call
+match, an absent receiver, or a chain with no nameable base all leave the match
+untouched — so inserting the call before every `out.push(grouped)` is safe even
+in the emitters that have three or four such paths.

+| C++        | `svc2.getUser()->save()` (control) | RESOLVES      | RESOLVES      |
+| PHP        | `$svc->getUser()->save()`          | VISIBLE-GAP   | INVISIBLE-GAP |
+| PHP        | `$this->repo->save()` (control)    | RESOLVES      | RESOLVES      |
+
+The C++ row is the one the plan flagged as having **no fixture anywhere** —
+`cpp-chain-call/` uses the value `.` form, which already worked. It now has one,
+plus the value-dot control that proves the defect was the `->` base specifically.
+
+### PHP: a measured residual, with the trap checked
+
+PHP does **not** resolve yet, and the plan's named trap — a language whose node
+type is missing from `extractMixedChain`'s tables reads as "didn't need it" when
+it in fact cannot be measured — is **not** the cause. Checked directly against
+the emitter:
+
+```
+name=save   chain=1|$svc|cgetUser   recv=$svc.getUser()
+```
+
+The leading `1` is the **v1** wire prefix current when this dump was taken; the
+codec is at v2 now (`2|$svc|cgetUser`), and a v2 decoder refuses a v1 payload by
+design — do not copy this literal into a fixture.
+
+The chain is minted correctly. The residual is that the fold's base, `$svc`,
+does not bind in the PHP resolver, so the fold returns `undefined` and the site
+falls through to the text cascade. That is PHP binding-key work, not a
+chain-layer defect, and it is left as a recorded residual rather than absorbed
+into this series.
+
+Two incidental corrections from that check, both to KTD6:
+
+- PHP's receiver capture text is normalized to `$svc.getUser()` — DOTS, not
+  `->`. So Case 0's "C-family punctuation" gate fires for PHP after all, which
+  is why the call chain was recorded as a VISIBLE-GAP to begin with.
+- Typing the fixture parameter (`function f(Service $svc)`) moved the row from
+  VISIBLE-GAP to INVISIBLE-GAP: with a type binding the cascade now types the
+  receiver but finds no member, so `compoundReceiverUnresolved` is false and no
+  drop is recorded. An untyped fixture parameter had been reporting a language
+  gap that was really a fixture defect — the same error class as the untyped
+  `$repo` control caught earlier.

+/**
+ * Receiver-resolution measurement harness.
+ *
+ * Answers one question — "how many method calls does GitNexus lose because it
+ * could not establish the receiver's type, and which source shapes are they?" —
+ * and answers it in a way that can gate a decision.
+ *
+ * TWO ARMS, because neither one alone is trustworthy:
+ *
+ *  1. SHAPE ARM (`--shapes`, default). A fixed matrix of receiver spellings —
+ *     every SHAPE_ID against every language — each cell classified by what the
+ *     graph actually contains:
+ *
+ *       RESOLVES       edge emitted. A test written against this shape starts
+ *                      green and proves nothing. Note this states only that an
+ *                      edge EXISTS — not that it points at the right target. A
+ *                      name-keyed fallback onto a same-named member reads as
+ *                      RESOLVES here, so a shape whose receiver has no
+ *                      well-defined type is not a usable control.
+ *       VISIBLE-GAP    no edge, and a `receiver-unresolved` drop was recorded.
+ *                      Measurable by the count arm below.
+ *       INVISIBLE-GAP  no edge, and NO drop was recorded. The call is lost and
+ *                      the instrument cannot see it.
+ *       N/A            the language's grammar does not admit this spelling.
+ *                      Carries a REQUIRED reason — an omitted cell and a
+ *                      genuinely inapplicable one look identical in a diff
+ *                      otherwise, and that is how coverage silently rots.
+ *       GRAMMAR-       the language's parser could not be loaded, so nothing
+ *       UNAVAILABLE    about it was measured. Neither passes nor fails the
+ *                      gate. Dart, Kotlin and Swift are vendored OPTIONAL
+ *                      grammars: they are skipped entirely by
+ *                      GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1, and they soft-fail
+ *                      when no vendored prebuild matches the host (the set
+ *                      covers darwin/linux arm64+x64 and win32-arm64 — a
+ *                      win32-x64 or musl host has none). Without this state an
+ *                      unloaded grammar emits no edges and every one of its
+ *                      cells reads as a resolution gap indistinguishable from a
+ *                      real regression.
+ *                      NOTE: all 14 load on a glibc linux-x64 host, so this
+ *                      state has no producer in the committed baseline. It
+ *                      guards the skip-flag and unsupported-host cases.
+ *
+ *     INVISIBLE-GAP is why this arm exists, and the series proved it: at the
+ *     time this arm was built `svc?.getUser().save()`, `svc.getTyped<User>().save()`
+ *     and `repos[0].save()` were all INVISIBLE, so fixing them moved the count
+ *     arm by exactly zero and a gate reading only the drop count would have
+ *     scored a working change as "no improvement". They resolve for TypeScript
+ *     now; the current per-shape state is `baseline.json`, never this comment.
+ *
+ *     COMPLETENESS IS ENFORCED: every language must declare a cell for every
+ *     SHAPE_ID, and every N/A must carry a reason. A missing cell fails the run
+ *     rather than being silently skipped.
+ *
+ *  2. COUNT ARM (`--corpus <repoPath>`). Runs the real pipeline over a repo and
+ *     reports drops SPLIT BY SITE KIND. The gate number is `call` only: the
+ *     recorder's gate tests the receiver's punctuation, not the site's kind, so
+ *     property reads (`d.source.kind`) and writes (`x.argtypes = [...]`) land in
+ *     the same bucket as lost method calls and would inflate it.
+ *
+ * KNOWN BLIND SPOTS — reported in every run, deliberately, because the number
+ * is a lower bound on a KNOWN-BIASED population and any delta measured later
+ * must be read against the same bias:
+ *
+ *   - Case 0 is reached by a receiver-TEXT punctuation test (`.` or `(`) OR by a
+ *     minted receiver chain, so a receiver spelled without that punctuation — a
+ *     subscript, PHP `->`/`::` — records a drop only where its emitter mints a
+ *     chain. Where none is minted the call still vanishes unrecorded.
+ *   - A drop is recorded only while `compoundReceiverUnresolved` stays true: if
+ *     the cascade types the receiver but finds no member, no drop is recorded
+ *     even though no edge was emitted, so an absent drop is not proof of
+ *     resolution. (Superseded claim, kept because it was quoted for several
+ *     units: `?.` and explicit type arguments DO produce a reference site —
+ *     what was absent was the edge and the drop, never the site.)
+ *
+ * MEASUREMENT HYGIENE — a run that skips this is void:
+ *
+ *   npm run build                       # the parse worker runs from dist/
+ *   rm -rf .gitnexus/parse-cache .gitnexus/parsedfile-cache
+ *   node --import tsx bench/receiver-resolution/measure.mjs --corpus <repo>
+ *
+ * `analyze --force` clears NEITHER cache, so a stale shard will happily serve
+ * the previous capture set and produce a confident, wrong number.
+ *
+ * Usage:
+ *   node --import tsx bench/receiver-resolution/measure.mjs
+ *   node --import tsx bench/receiver-resolution/measure.mjs --corpus /path/to/repo

+# Schema pair-set bench (#2793)
+
+What a bigger `CodeRelation` FROM/TO pair set costs at query time, measured
+against a real `@ladybugdb/core` database.
+
+```bash
+# from gitnexus/
+node --import tsx bench/schema-pairs/measure.mjs           # print one JSON line per size + a summary
+node --import tsx bench/schema-pairs/measure.mjs --check    # gate vs baselines.json
+```
+
+## Why it exists
+
+`src/core/lbug/schema.ts` generates its relation pairs from two cross products,
+and declines to add a third one **on the strength of a number** — roughly 1.04×
+at 450 declared pairs, 1.6× at 786, 2.1× at 1024. That measurement used to live
+in a scratch directory, so nobody proposing a third rule could re-run it. This
+harness is that measurement, committed — and it reproduces those figures.
+
+Run it before widening a rule, and quote the new ratio in the review.
+
+Observed on the reference box, **four runs** (ratios vs the 332-pair list):
+
+| pairs | untyped    | typed (floor) |
+| ----- | ---------- | ------------- |
+| 332   | 1.00×      | 1.00×         |
+| 450   | 0.93–1.05× | 0.98–1.17×    |
+| 641   | 1.22–1.43× | 1.11–1.23×    |
+| 786   | 1.52–1.75× | 1.19–1.31×    |
+| 1024  | 2.03–2.34× | 1.31–1.57×    |
+
+Production's 450 came out _faster_ than 332 on three of the four runs, so at this
+size the pair count is inside run-to-run noise. Everything past ~640 is not.
+**Quote the range, not a single run** — one run is not evidence here.
+
+## What it measures
+
+For each pair-set size it builds a fresh database with all 32 node tables, a
+`CodeRelation` table declaring exactly that many FROM/TO pairs, and **identical
+data**, then times two query shapes over 40 anchors × 15 reps (median):
+
+- **`untyped_ms_<size>`** — `MATCH (a {id: $id})-[r:CodeRelation]->(b)`. Neither
+  endpoint is labelled, so LadybugDB must treat every declared pair as a
+  candidate. This is the shape `impact`, `context` and `detect_changes` issue
+  when they walk out from one node id, and the only one whose plan depends on
+  how many pairs the table declares.
+- **`typed_ms_<size>`** — `MATCH (a:Function {…})-[r]->(b:Function)`, the lower
+  bound. Both endpoints labelled prunes the plan to a single pair, so this was
+  expected to be flat in the pair count. **It is not** — up to 1.17× at 450 and
+  1.57× at 1024 — so a declared-but-unused pair costs something even when the
+  planner never considers it. `typed_ratio_*` is therefore the floor, not a noise
+  control; the real cost of widening sits between it and `ratio_*`. A run where
+  `typed_ratio` moves _more_ than `ratio` is noise-dominated and should be
+  rerun.
+- **`ratio_<size>`** — `untyped_ms_<size> / untyped_ms_332`. `ratio_450` is the
+  figure `schema.ts` quotes.
+
+### Sizes
+
+The pair set is a prefix of a fixed 32×32 (`NODE_TABLES`²) enumeration, so each
+size is a strict superset of the smaller ones. The four pairs the synthetic data
+uses are pinned to the front, so **the same rows are reachable by the same query
+at every size** — the only variable is how many unused pairs are declared. The
+harness fails if the row counts ever differ across sizes.
+
+| size | what it is                                                                                                                                                                                                |
+| ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| 332  | the pre-#2792 hand-written list — the reference for every ratio                                                                                                                                           |

+| 641  | the third cross product `schema.ts` defers (`DEFINITION_ANCHOR_LABELS × {CodeElement, Section, Typedef, Union, Namespace, Impl, TypeAlias, Static, Template}`), which would leave ~29 hand-declared lines |
+| 786  | the size an earlier revision of that comment attributed to the third rule — it is 641; kept as a measured waypoint                                                                                        |

+
+## Correctness gate
+
+Before timing anything, the harness round-trips the **real** `SCHEMA_QUERIES`
+through a real database and asserts that `CALL SHOW_CONNECTION('CodeRelation')`
+reports exactly the pairs `parseRelationSchemaPairs` finds in `RELATION_SCHEMA`.
+
+No magic number is baked in: the invariant is that the DDL LadybugDB _accepted_
+carries the pair set our own parser believes it declares. The absolute count is
+reported as `declared_pairs`. A pair declared twice would not reach this check at
+all — LadybugDB rejects the `CREATE REL TABLE` outright, which is why a duplicate
+kills every `analyze` rather than one repository's.
+
+## What it does NOT measure
+
+- **Ingest / `COPY` cost.** Pair-set size also multiplies the number of per-pair
+  CSVs the emitter routes to (`src/core/lbug/rel-pair-routing.ts`); that cost is
+  covered by `bench/emit-persistence`.
+- **At-scale absolute numbers.** Row counts here are small and deliberately
+  constant. The ratios are the signal; the milliseconds are box-specific.
+
+## Regenerating the baseline
+
+`baselines.json` holds one budget, `ratio_450_budget` — the ceiling on what
+production's own pair count may cost relative to the 332-pair hand-list it
+replaced. Re-run without `--check` **several times** and copy the top of the
+observed `ratio_450` range plus headroom — the spread between runs on this box
+is wider than the effect being measured at 450, so a single run cannot set it.

+ * What a bigger `CodeRelation` FROM/TO pair set costs at query time (#2793).
+ *
+ * `src/core/lbug/schema.ts` declares its relation pairs from two cross products
+ * plus a small hand-written remainder, and it justifies NOT adding a third cross
+ * product with a number: anchored queries cost ~1.04× at 450 declared pairs but
+ * 1.6× at 786 and 2.1× at 1024. That measurement previously lived in a scratch
+ * directory, so the claim could not be re-checked when someone proposed
+ * widening a rule. This is it, committed.
+ *
+ * WHAT IT MEASURES. Against a real `@ladybugdb/core` database, with byte-identical
+ * DATA at every size, it times the query shape whose plan actually depends on the
+ * declared pair set:
+ *
+ *   MATCH (a {id: $id})-[r:CodeRelation]->(b) RETURN b.id
+ *
+ * Neither endpoint is labelled, so LadybugDB must consider every declared
+ * FROM/TO pair as a candidate — this is the shape `impact`, `context` and
+ * `detect_changes` all issue when they walk out from one node id.
+ *
+ * A LABEL-typed query (`MATCH (a:Function)-[r]->(b:Function)`) is measured
+ * alongside it as the LOWER BOUND. Its plan prunes to a single pair, so it was
+ * expected to be flat in the pair count — it is NOT. Measured here it reaches
+ * 1.17× at 450 and 1.57× at 1024 against the same 332-pair reference, i.e. a
+ * declared-but-unused pair costs something even when the planner never
+ * considers it (per-pair catalog/storage overhead the query pays regardless).
+ * So `typed_ratio_*` is not a noise control: it is the floor, and the true cost
+ * of a wider pair set lies between it and `ratio_*`. Treat any run where
+ * `typed_ratio` moves MORE than `ratio` as noise-dominated.
+ *
+ * SIZES. The pair set is a prefix of a fixed 32×32 (`NODE_TABLES`²) enumeration
+ * so every size is a strict SUPERSET of the smaller ones, and the four pairs the
+ * data actually uses are pinned first — so the same rows are reachable by the
+ * same query at every size, and the only variable is how many UNUSED pairs the
+ * table declares:
+ *   -  332 — the pre-#2792 hand-written list (the historical baseline);
+ *   -  450 — production today (two cross products + 72 hand-declared);
+ *   -  641 — the third cross product schema.ts defers
+ *            (`DEFINITION_ANCHOR_LABELS × {CodeElement, Section, Typedef, Union,
+ *            Namespace, Impl, TypeAlias, Static, Template}`), which would leave
+ *            only ~29 hand-declared lines;
+ *   -  786 — the size an earlier revision of that comment attributed to the
+ *            third rule (it is 641; 786 is kept as a measured waypoint);

+/**
+ * Scope-emission bench (#2699).
+ *
+ * JavaScript/TypeScript gained block scopes so that `let`/`const` in sibling
+ * blocks are distinct bindings. Emitted naively — one scope per
+ * `statement_block` — that TRIPLED the block-scope count and cost ~10% of
+ * analyze wall time, because every scope-chain walk in every function then
+ * steps through levels that bind nothing.
+ *
+ * Two emit-side filters keep the semantics and drop the waste:
+ *   1. a block that IS a function body duplicates the enclosing Function scope;
+ *   2. a block that declares no `let`/`const`/`class`/`function` binds nothing,
+ *      so it is transparent to every lookup.
+ *
+ * This bench guards that. It counts scope captures over a synthetic corpus
+ * whose shape is fixed in this file, so the numbers are exact and independent
+ * of the machine — unlike wall-clock analyze, where a 2% effect sits well
+ * inside the noise of a shared runner (measured: ±10% run to run).
+ *
+ * BOTH languages are measured. The filters are implemented twice —
+ * `FUNCTION_BODY_OWNER_TYPES` in `typescript/captures.ts` and
+ * `JS_FUNCTION_BODY_OWNER_TYPES` in `javascript/captures.ts`, each with its own
+ * `blockDeclaresBinding` and its own `BLOCK_BINDING_CHILD_TYPES` — so a
+ * TypeScript-only bench would let a JavaScript-only regression ship green.
+ *
+ * On this corpus the two currently agree exactly (2 blocks per module, 2200
+ * scopes). That is a measured result, not a required invariant: the fixtures
+ * are structurally parallel and the TS-only syntax they drop carries no extra
+ * scopes. Each language is still gated against its OWN baseline, because the
+ * filters are separate code and nothing enforces that the counts stay equal.
+ *
+ * Usage:
+ *   node bench/scope-emission/measure.mjs           # print measurements
+ *   node bench/scope-emission/measure.mjs --check   # gate against baselines
+ *
+ * Build-free: imports the TypeScript sources through tsx, like the other
+ * benches here.

+ * produce byte-identical analyzer-identity path fields (#2668).
+ *
+ * `realpathSync.native` canonicalizes 8.3 short names and symlinks but does not
+ * guarantee the drive-letter case it returns — it can preserve whatever casing
+ * the caller's path carried, and `import.meta.url` casing depends on how each
+ * entry process (CLI shim vs `npx`/npm wrapper vs server worker) was launched.
+ * When `analyze` stamps `build.rootPath` under one casing and `status`
+ * recomputes it under another, `analyzerRunnerIdentitiesEqual` deep-compares
+ * unequal and `status` reports a freshly-analyzed, untouched repo as stale.
+ * Uppercasing the drive letter (drive letters are case-insensitive; uppercase
+ * is the conventional form) collapses that variance. POSIX paths are returned
+ * unchanged. `platform` is explicit so the transform is unit-testable off
+ * Windows.
+ *
+ * The optional `\\?\` extended-length prefix is preserved and the drive letter
+ * after it is still normalized; UNC paths (`\\server\share`, `\\?\UNC\...`)
+ * have no drive letter and are left untouched.
+ *
+ * That optional group is defensive, not a case `realpathSync.native` produces:
+ * libuv's `fs__realpath_handle` strips `\\?\` (and rewrites `\\?\UNC\` back to
+ * `\\`) before returning, so the prefix can only reach here from caller-supplied
+ * input, which `path.resolve` preserves (#2667).
+ *

+ * half of it while `analyze` still exits 0 (#2790). Shaped after Resilience4j's
+ * `failureRateThreshold` + `minimumNumberOfCalls`: judge a failure RATE, but
+ * only once enough sub-batches have been attempted for a rate to mean anything
+ * — a 3-node repo losing its single sub-batch is 100% and must not abort. The
+ * rate sits below a live-traffic breaker's 50% (a batch indexer's job is to
+ * index the whole corpus, not to serve degraded traffic) and above Hadoop's
+ * single-digit `mapreduce.map.failures.maxpercent` (tolerating transient
+ * hiccups is the entire point of #2790).
+ *
+ * The sample floor SCALES with the run; it used to be a flat 20. A flat floor
+ * can exceed a run's ENTIRE sub-batch budget, and then the guard is not "not yet
+ * armed" — it is structurally off. Every resume run has exactly that shape by
+ * construction: its node set is only the pending ids, so it produces few
+ * sub-batches no matter how large the repo is, and the run whose whole purpose
+ * is retrying a suspect endpoint was the one run this guard could never fire in.
+ * Resilience4j can afford a constant `minimumNumberOfCalls` because a breaker
+ * sits on an unbounded call stream — the sample always arrives eventually; a
+ * batch indexer has a finite budget, so the minimum has to be expressed relative
+ * to it. Hadoop's `mapreduce.map.failures.maxpercent` takes the other extreme, a
+ * pure percentage with no minimum at all, which is why a 1-of-1 failure reads as
+ * "100% failed" there. The clamp below keeps both ends honest:
+ *
+ *   floor = clamp(ceil(totalNodes / subBatchSize / 2), 5, 20)
+ *
+ *  - ceil(totalNodes / subBatchSize / 2): the run's own sub-batch budget, halved
+ *    — so the rate is judged over the back half of a short run: a real sample,
+ *    still early enough to stop the run before it walks the rest of the corpus.
+ *    Derived from the ACTUAL `subBatchSize` rather than assuming the default of
+ *    8, because `GITNEXUS_EMBEDDING_SUB_BATCH_SIZE` is exactly the knob an
+ *    operator turns for a constrained or flaky endpoint — the population this
+ *    guard protects — and a floor computed against the wrong divisor is the same
+ *    structurally-off guard, just at a different repo size. Nodes that chunk
+ *    into several chunks only produce MORE sub-batches, so the guard arms
+ *    earlier still.
+ *  - min 5: under five attempts a "rate" is one or two coin flips. A 3-node repo
+ *    losing its single sub-batch is 100% and must be tolerated, not aborted —
+ *    the exact case the old flat floor was written to protect, kept intact.
+ *  - max 20 (the previous flat value, reached once a run has 40 sub-batches):
+ *    large runs keep today's behavior byte for byte, and a purely proportional
+ *    floor would perversely WEAKEN the guard at scale — half a 20k-node repo's
+ *    sub-batches is 1250 of them (at subBatchSize 8) eaten before a rate could
+ *    abort anything.
+ *
+ * Honest limit: this bounds the failure RATE, never the absolute loss. A run
+ * that steadily fails just under 25% of its sub-batches never aborts, so a
+ * single run may drop up to a quarter of the corpus and still exit 0 behind one
+ * warning line. That is by design — the dropped nodes are left holding ZERO rows
+ * so the next incremental run re-embeds them, which beats failing the whole
+ * analyze — but it is the real ceiling on what this guard promises.
+ *
+ * ponytail: lifetime ratio, evaluated only when a sub-batch fails. A sliding

  *      resolved.
  *   3. **Dynamic require** — `require(computedPath)` is skipped (non-literal
  *      argument — cannot statically resolve the target).
- *   4. **`module.exports` / `exports.X`** — CJS export forms are not yet
- *      modeled as re-exports. The finalize algorithm treats the exporting
- *      module as a namespace; importers that do `const X = require('./m')`
- *      bind the module namespace, and member-call resolution walks the
- *      class graph from there.
+ *   4. **CommonJS `require()` in TypeScript** — `require()` decomposition is a
+ *      JavaScript-emitter concern, so a `.ts` file's `const m = require('./m')`
+ *      is not decomposed into an import. The EXPORT side of a `.ts` CommonJS
+ *      module is now declared (shared with the JS emitter), but an importer
+ *      written in TypeScript still cannot resolve through it.
+ *   5. **`.cjs` module-level `this`** — the CommonJS/ESM gate consults the file
+ *      extension where it can, but `provider.labelOverride` receives no file
+ *      path, so a `.cjs` file whose only export is a module-level `this.X = fn`
+ *      is not labelled. It now emits nothing rather than an ownerless `Method`.
+ *   6. **Calling a renamed default-export binding** — `module.exports = fn` IS
+ *      indexed (#2723, named after the file), but resolving a CALL through a
+ *      renamed local binding (`const renamed = require('./mod'); renamed()`)
+ *      needs the finalize layer to treat a called namespace binding as the
+ *      target module's default export. `const mod = require('./mod'); mod()`
+ *      happens to resolve because the names coincide.
+ *   7. **Anonymous ESM default** — `export default function () {}` (no name)
+ *      is not indexed either. Same class as the CJS default above, different
+ *      construct; not addressed by #2723.
+ *
+ * ## CommonJS export forms (#2723)
+ *
+ * Each of these declares its name in the module scope, so importers resolve to
+ * it by name — `const { foo } = require('./m')` matches directly and a
+ * namespace `m.foo()` walks the module's defs:
+ *
+ *   - `exports.foo = function () {}` / `module.exports.foo = (a) => a`, in
+ *     every value form (function, async, arrow, async arrow, generator).
+ *   - `const e = exports; e.foo = fn` — an alias bound at module scope. The
+ *     receiver cannot be pinned in a query, so the member-assignment rules
+ *     match any identifier receiver and the emitters prune anything that is
+ *     not the exports object.
+ *   - `this.foo = fn` at MODULE level of a CommonJS file, where `this` is
+ *     `module.exports`. Gated on the file being CommonJS — in ESM top-level
+ *     `this` is undefined and the same line exports nothing.
+ *   - `exports.foo = lib.imported` / `exports.foo = importedName` — forwarded
+ *     as a re-export (`reexport-alias`), so callers reach the ORIGINAL
+ *     definition. A plain import binding would not do: it is private to its
+ *     module, exactly as in ESM.
+ *   - `module.exports = fn` — the whole module is the callable, so it is named
+ *     after the file (`index.js` takes its parent directory). A named function
+ *     expression keeps its own name. `exports = fn` is NOT indexed: rebinding
+ *     `exports` exports nothing in CommonJS, it only breaks the alias.
+ *
+ * Two deliberate non-cases. `exports.foo = localFn`, where the value is a
+ * locally declared function, needs nothing — the module scope already binds
+ * `localFn` and importers already resolve through it. And a CJS export whose
+ * name the module ALSO declares lexically is suppressed rather than declared
+ * twice: two declarations of one name are ambiguous, and the resolver would
+ * drop the intra-module edge entirely.
+ *
+ * Callable members assigned through a receiver are Methods with an owner edge
+ * rather than free functions: `Foo.prototype.bar = fn` and `this.bar = fn`
+ * inside a constructor. Ownership resolves to what the file declares, so an
+ * owner it cannot see (`External.prototype.x = fn`) claims no edge.

+ * Rust module paths — the module tree, expressed over the scope model.
+ *
+ * rustc resolves `a::b::dispatch` against a MODULE TREE, not a file tree: `mod`
+ * is an item with its own `DefId`, and a path's leading segments name modules in
+ * the *type* namespace (which is why a same-named `fn` can never shadow them —
+ * functions live in the value namespace). GitNexus models the same tree in two
+ * halves, and this module joins them:
+ *
+ *   - **Inline modules** (`mod inner { … }`) are `Namespace` scopes owning a
+ *     `Namespace` def, so the shared `tagNamespacePrefixes` pass stamps members
+ *     with `namespacePrefix = 'inner'` / `'outer.inner'`.
+ *   - **File modules** (`mod tools;` loading `tools.rs` or `tools/mod.rs`) leave
+ *     no in-file marker at all — the module path lives in the FILE PATH relative
+ *     to the crate root. That half is reconstructed here.
+ *
+ * ## Module identity carries its crate
+ *
+ * A module is `{ crateRoot, segments }`, never bare segments. A cargo workspace
+ * routinely gives several members the same internal module name — `util`,
+ * `error`, `config`, `types` are near-universal — and identity by segments alone
+ * makes `crates/a/src/tools.rs` and `crates/b/src/tools.rs` the same module. That
+ * mis-binds a call across crates when only one defines the member, and (worse)
+ * ties the lookup when both do, so qualified resolution refuses and the call
+ * falls back to the lexical walk that #2730 exists to prevent. Rust has no
+ * implicit cross-crate paths: reaching another crate requires naming it, so two
+ * modules in different crates are never the same module.

+/**
+ * Rust module-qualified call resolution (#2730) — path resolution over the
+ * module tree, the way rustc does it.
+ *
+ * `tools::dispatch(ctx, name)` is captured as a FREE call whose `name` is the
+ * tail identifier and whose written path rides along in `site.rawQualifiedName`
+ * (the same channel #1982 built for qualified inheritance bases). Without
+ * consulting that path, the shared scope-chain walk resolves the bare tail and
+ * binds it to whatever `dispatch` is lexically nearest — which, for the wrapper
+ * idiom `fn dispatch(..) { tools::dispatch(..) }`, is the wrapper itself. The
+ * real cross-module edge then does not exist and `impact` reports the callee as
+ * unreached.
+ *
+ * The fix follows rustc's actual rule rather than a filename heuristic:
+ *
+ *   1. A path's leading segments name MODULES, resolved in the type namespace.
+ *      A same-named `fn` lives in the value namespace and therefore can never
+ *      shadow them — which is exactly the shadowing this bug was about.
+ *   2. `crate::` / `self::` / `super::` are prefix transforms on the caller's
+ *      own module path, not reasons to give up.
+ *   3. The final segment is a MEMBER of the resolved module — looked up in that
+ *      module's binding table, so `pub use` re-exports resolve like any other
+ *      binding.
+ *
+ * Module identity comes from `module-path.ts`: file path below the crate root,
+ * plus any enclosing `mod` blocks (carried on `namespacePrefix`, stamped by the
+ * shared `tagNamespacePrefixes` pass now that `mod_item` emits a Namespace def).
+ *
+ * Refuses — returns `undefined`, leaving the shared chain untouched — whenever
+ * the path names no known module, the module has no such member, or two
+ * candidates tie. A wrong CALLS edge is worse than a missing one: it is what
+ * made this issue dangerous in the first place.

+ * Blank nested Swift conditional-compilation directives before parsing.

+ * (`vendor/tree-sitter-swift/src/node-types.json`), so error recovery can
+ * discard the enclosing declaration. Replacing only the directive text with
+ * spaces preserves `.length`, line endings, and every declaration offset.
+ *
+ * ponytail: delete this file (and the `preprocessSource` wiring in `swift.ts`)
+ * once a vendored tree-sitter-swift release includes upstream PR #583 ("Allow
+ * #if/#elseif/#else/#endif directives inside type bodies"); see also upstream
+ * issue #298 and PR #599. `.github/vendored-grammars.json` has no `"hold"` on
+ * swift, so the bump bot will land that release on its own.
+ *
+ * A directive group is blanked only when **all** of these hold:
+ *
+ *   - it opens at `braceDepth > 0` — nesting, not indentation, is what the
+ *     grammar rejects; top-level directives are valid source-file members and
+ *     are left intact
+ *   - it is not inside a multiline string literal or a block comment — blanking
+ *     a line that carries a block-comment terminator would un-terminate the
+ *     comment and swallow the rest of the file, and blanking inside a literal
+ *     would rewrite program data
+ *   - every branch is brace-balanced. A group that splits a declaration header
+ *     (`#if` … `func f() async {` … `#else` … `func f() {` … `#endif`) leaves
+ *     one unmatched `{` once both branches survive, which re-parents every
+ *     later top-level declaration. Such a group degrades to the pre-fix
+ *     behavior instead.
+ *
+ * Known residuals, all of which degrade to "directive left in place" rather
+ * than to corrupted output: string interpolation is not parsed with full Swift
+ * expression fidelity, so a nested multiline string inside an interpolation can
+ * confuse the scanner; a bare `/…/` regex literal containing `/*` opens a
+ * phantom block comment; and a multiline extended regex literal is treated as
+ * ending at its first line.
+ *
+ * Byte length is *not* preserved when a blanked directive line carries
+ * non-ASCII trailing text (`  #if os(iOS) // 日本語 🔥` is 23 UTF-16 code units
+ * either way, but shrinks from 31 UTF-8 bytes to 23). C++ sidesteps this
+ * because UE macro tokens are ASCII-only; a Swift directive line can carry any
+ * trailing comment. Per the `LanguageProvider.preprocessSource` contract this is
+ * safe only while no consumer slices the original UTF-8 bytes by `startIndex`:
+ * node-tree-sitter reports UTF-16 code-unit indices, and every in-process
+ * consumer slices the JS string, whose `.length` *is* preserved.
+ *
+ * Must stay pure and idempotent — see `LanguageProvider.preprocessSource`.

+/**
+ * Shadowed CommonJS export-assignment detection (issue #2723).
+ *
+ * The CJS declaration rules in the JS/TS scope queries bind the bare property
+ * name of `exports.X = function () {}` / `module.exports.X = (a) => a` into the
+ * enclosing module scope, so importers resolve to it by name. That is the whole
+ * point of #2723 — without it the graph node exists and nothing resolves to it.
+ *
+ * But a file may ALSO declare that same name lexically:
+ *
+ *   function dup(v) { return v; }
+ *   exports.dup = function (v) { return !v; };
+ *   function callIt(v) { return dup(v); }
+ *
+ * Then the module scope holds TWO declarations named `dup`, the name is
+ * ambiguous, and the resolver drops `callIt -> dup` altogether — an edge that
+ * resolved fine before #2723. A silently missing caller is worse than the gap
+ * #2723 set out to close, so the emitter drops the CJS declaration in exactly
+ * this case: the lexical declaration already supplies the module-scope name,
+ * so importers still resolve, and intra-module resolution is unchanged from
+ * before #2723.
+ *
+ * Only the `@declaration.function` match is suppressed. The graph node comes
+ * from a separate query (`tree-sitter-queries.ts`) and collapses onto the
+ * lexical declaration's node by name anyway, so no node is lost.
+ *
+ * Shared by both the JavaScript and TypeScript capture emitters — every
+ * grammar node named here (`assignment_expression`, `member_expression`,
+ * `property_identifier`, `function_declaration`, `lexical_declaration`,
+ * `variable_declaration`, `export_statement`) exists in both
+ * `tree-sitter-javascript` and `tree-sitter-typescript`.

- * by `properties.language` to the per-language field matchers registered in
- * `di-extractors/` (`DI_MATCHERS` — same registry seam shape as
- * `SCOPE_RESOLVERS`), then fans each match out to `INJECTS` edges from the
- * consumer Class node to every Class implementing the matched element
- * interface.
- *
- * This file names NO language or framework: which fields count as
- * container-injected — and why — is entirely the registered matcher's
- * business (see `di-extractors/` for the matchers and their semantics,
- * including deliberate annotation exclusions). The matcher also supplies the
- * human-readable edge `reason`, so framework specifics stay in the payload,
- * never in this phase.
- *
- * The resolution uses ONLY graph data — Property nodes, `HAS_PROPERTY` edges,
- * `IMPLEMENTS` edges, and Interface nodes. No filesystem access is performed:
- * the structural information was already extracted by earlier parse /
- * structure phases.
- *
- * Interface resolution is scoped to the CANDIDATE'S OWN language and prefers
- * qualified names: a dotted element type resolves via the language's
- * `qualifiedName` index; a bare simple name resolves only while unique within
- * that language. Ambiguous names — simple OR qualified (a qualifiedName has
- * no file-path component, so the same package+name duplicated across monorepo
- * modules collides too) — fail CLOSED — no edge, never
- * last-writer-wins — but observably: skips are counted in the phase output's
- * `ambiguousSkipped` and named in an isDev debug log, so "no DI fields" is
- * distinguishable from "all candidates ambiguous". Same-package/import-aware
- * disambiguation is a documented follow-up (see the plan's Deferred work).
+ * Framework-neutral dependency-injection resolution. Per-language resolvers
+ * identify injection sites and provider metadata; this phase performs only

+ * validated against heap probes at chunks 25/50/75 of 113 — the first
+ * calibration divided by total scanned files and under-projected by ~30%),

+ * feed a WARNING and an emergency abort, never a hard admission gate, so
+ * estimate error only shifts when the operator hears about the problem, not
+ * whether analyze runs.
+ *
+ * RECALIBRATED for streamed structural emit (#2680), which is on by default for
+ * full rebuilds and holds relationships out of the JS heap. The original 2250
+ * was measured against the object-based graph; an A/B at 400k nodes / 1.08M
+ * edges put streaming at 1.40x smaller (819 MB -> 584 MB), so the corpus-
+ * calibrated figure is divided by that ratio: 2250 / 1.40 ~= 1600. Scaling the
+ * measured constant rather than substituting a synthetic one keeps #2649's
+ * kernel calibration intact and changes only the one thing that actually moved.
+ *
+ * If streaming is disabled (GITNEXUS_STREAM_GRAPH_EMIT=0, or any non-force run)
+ * this UNDER-projects by ~40%, so the preflight warning may stay quiet on a repo

+   * returned nothing for `list[0]`, and TypeScript did the reverse. Two entries
+   * answering one question, each accreting an implementation per language.
+   *
+   * `via` carries the route so a provider can distinguish them where it matters
+   * (a `Dictionary` yields its VALUE type by subscript but either type by
+   * accessor name); a provider that does not care can ignore it.
+   *
+   * Consulted ONLY where the source actually performed the access. It is NOT a
+   * general type-name normalizer: unwrapping a container at a bare class lookup
+   * would let `repos.find(x)` fold to `Repo.find`, because a container's member
+   * set is not its element's. For the same reason it is deliberately separate
+   * from `stripTypePreservingDecoration`: a pointer or a nullable leaves the
+   * member set unchanged and is safe to strip at the lookup; a container is not.
+   *
+   * ## The `index` route is REQUIRED, and `undefined` means "not a container"
+   *
+   * A language that leaves the `index` route unanswered gets NO index folding —
+   * the structural fold declines the step rather than passing the position
+   * through. That is not a default worth softening. `undefined` used to mean
+   * "fall back to identity", on the theory that a capture layer which already
+   * reduced the container (Go's `normalizeGoTypeName`, C#/TypeScript's
+   * `stripGeneric`) leaves nothing to unwrap. The theory holds for a container;
+   * it is false for an ordinary class the source happened to subscript, and
+   * `rawName` cannot tell those apart — `repos: User[]` and `grid: Grid` both
+   * arrive as a bare resolvable class name. Identity there typed `grid[0].run()`
+   * as `Grid.run` and `t[0].Render()` as `Table.Render`: a wrong owner, which
+   * this pipeline ranks strictly below a missing edge.
+   *
+   * The hook is therefore handed `TypeRef.declaredSpelling` — the annotation AS
+   * WRITTEN, retained by the scope extractor precisely because capture-time
+   * normalization destroys it — falling back to `rawName` only when nothing was
+   * normalized away. So a provider sees `User[]`, `List[User]`, `[]*User` or
+   * `Dictionary<string, User>`, never the post-reduction `User`, and answering
+   * `undefined` for a spelling it does not recognize as a container is an
+   * ANSWER, not an absence.
+   *
+   * Implementations may return a still-DECORATED element name (Go's `[]*User`

+ * branch consults its `processedDefinitionNodes` set, so suppression worked only
+ * if the function match happened to be processed first. It is not: tree-sitter
+ * completes the const pattern at `@name`, while the function pattern must also
+ * match the trailing `(arrow_function)` / `(function_expression)` value, so the
+ * const match is yielded FIRST and the edgeless `Const:` twin escaped.
+ *
+ * Consulting this set makes the outcome independent of match order.
+ *
+ * ## Keying
+ *
+ * Keys are `startIndex:name`, never `startIndex` alone — a multi-name
+ * declaration (`const a = 1, b = () => {}`) shares ONE definition node, and a
+ * bare-index key would wrongly suppress `a`'s legitimate `Const` node.
+ *
+ * Labels come from {@link getLabelFromCaptures}, the same function the main loop
+ * uses, so the pre-scan and the loop can never disagree about what counts as a
+ * value capture — including when a provider's `labelOverride` reclassifies one.
+ * A match that resolves to a value label registers nothing, so a match can never
+ * suppress itself.
+ *

  * never sees a parser node and shared ingestion code never branches on a

+ *
+ * ## The cell/site model
+ *
+ * A *cell* is a named storage location that may hold a callable — a variable,
+ * parameter, field or pointer, canonicalized to a binding key by the scope
+ * tree. A *site* is one observed fact about cells, emitted here as a capture
+ * match and consumed by `passes/callable-value-flow.ts`, which runs them to a
+ * fixpoint. The site kinds (`CallableFlowSite`) are:
+ *
+ * - `seed` — a cell acquires a named callable: `f = target`. Carries
+ *   `@callable-flow.target-name`, the name the pass resolves against.
+ * - `copy` / `alias` — a cell takes another cell's contents, so targets flow
+ *   between them.
+ * - `address` / `store` / `load` — indirection through a pointer cell.
+ * - `formal` — a parameter cell of a known function, by index.
+ * - `argument` — a callable passed at a call site, binding to that `formal`.
+ * - `invoke` — a call THROUGH a cell (`f()`), the site that ultimately becomes
+ *   a `CALLS` edge once the cell's target set is known.
+ *
+ * ## The anonymous-callable convention
+ *
+ * A closure literal has no name to resolve against, so a `seed` whose source
+ * is an anonymous callable takes its **destination's** name as
+ * `@callable-flow.target-name` — `val f = { }` seeds "the cell `f` holds the
+ * callable named `f`". That is deliberately self-referential and only resolves
+ * because the binding itself is a callable target: `buildGraphTargetIndex`
+ * admits it on the label of the graph node it resolves to, which #2687 makes a
+ * `Function` for exactly this construct. Languages whose closure binding does
+ * NOT emit a callable graph node get no resolution from the convention alone
+ * (#2693).
+ *
+ * ## Adding a language
+ *
+ * Supply `CallableFlowCaptureOptions` from `<lang>/captures.ts` and call
+ * `synthesizeCallableFlowCaptures`. Two recurring traps:
+ *
+ * - A **fieldless** assignment/binding node decomposes to nothing under the
+ *   shared `left`/`name`/`value` fallback in `assignmentParts`. Supply
+ *   `extractAssignment` (Kotlin's `assignment`, Dart's
+ *   `initialized_identifier`). Returning `undefined` falls back to the shared
+ *   path, so one callback can handle the odd node and leave the rest alone.
+ * - A binding needs a `SymbolDefinition` for the pass to attach to. Captures
+ *   alone are not enough: without a `@declaration.*` for the bound name, the
+ *   seed has no cell to key on.
+ *
+ * `c/captures.ts` is the fullest worked example (pointers, signatures,
+ * overload selection); `dart/captures.ts` the smallest interesting one.

+ * Receiver-chain codec.
+ *
+ * THE one encoder/decoder for the compact receiver chain carried on
+ * `ReferenceSite.receiverChain`: the capture emitters write it, the
+ * scope-resolution fold reads it, and the durable ParsedFile store validates
+ * it. Two hand-rolled copies of a wire format drift — every side MUST import
+ * from here. (`taint/path-codec.ts` is the in-repo precedent for both the
+ * discipline and the shape.)
+ *
+ * ## Why a string rather than `MixedChainStep[]`
+ *
+ * `makeInterningReviver` (parsedfile-store.ts) interns strings, but it
+ * re-shares OBJECTS only when they carry `nodeId` + `filePath`. A
+ * `MixedChainStep` has neither, so an object encoding leaves every step object
+ * and every chain array as a distinct allocation on every warm load, while a
+ * string collapses to one interned instance per distinct chain.
+ *
+ * ## Wire format (version `2`)
+ *
+ * ```
+ * 2|<base>|<step>|<step>…[|~]
+ * ```
+ *
+ * - One-character version prefix, then the BASE receiver name, then ordered
+ *   base-first steps.
+ * - Each step is a one-character kind sigil followed by the member name:
+ *   `c` = call (`getUser()`), `f` = field (`address`). The sigil is the first
+ *   character of the segment and the name follows immediately, so a member
+ *   whose name begins with `c` or `f` needs no escaping (`ccount` decodes as a
+ *   call to `count`).
+ * - `a` = await and `i` = index are NAME-FREE and encode as a BARE sigil: an
+ *   awaited call's name already lives on its `c` step, and a subscript's key is
+ *   a value rather than an identifier the resolver could look up. The decoder
+ *   rejects any trailing characters after `a` or `i`, which is what keeps an
+ *   accidentally empty-name `c` or `f` segment refusing instead of decoding as
+ *   one of these.
+ * - A trailing `|~` segment is the TRUNCATION MARKER. NOTE: no current producer
+ *   mints one. `extractMixedChain` signals "stopped early" by returning
+ *   `baseReceiverName: undefined`, and the encoder requires a base, so a
+ *   truncated chain is unrepresentable rather than merely unused. The marker and
+ *   the decoder/fold guards are kept as a forward-compatible contract: a future
+ *   producer that CAN report a partial chain must set it, and the fold already
+ *   refuses such chains. Read the `truncated` field as "reserved", not "live". the chain hit
+ *   `MAX_CHAIN_DEPTH` and what is encoded is a base-side PREFIX of the real
+ *   chain. A consumer MUST treat a truncated chain as unusable for typing —
+ *   the missing tail is exactly what determines the final type — but never as
+ *   an error.
+ *
+ * `|` and `~` cannot appear in an identifier in any supported language, so the
+ * format needs no escaping and a malformed payload cannot silently decode as a
+ * different valid chain.
+ *
+ * For `svc.getUser().address.save()`, the receiver of `save` encodes as

+/**
+ * Streaming structural graph-emit sink (issue #2680).
+ *
+ * `analyze` holds the whole `KnowledgeGraph` on the main thread for the entire
+ * pipeline, so peak heap is O(repo) — ~2.1 KB/node at Linux-kernel scale
+ * (#2649). Measurement on a kernel-shaped synthetic graph (400k nodes,
+ * 2.7 edges/node) says where that goes:
+ *
+ *   nodes only .......  367 B/node
+ *   nodes + edges .... 2075 B/node   <- reproduces the #2649 figure
+ *
+ * So **relationships are ~83% of graph heap** (~646 B/edge), and that is what
+ * this sink removes. 646 B for an object holding four short strings is the cost
+ * of storing every edge four times over — `relationshipMap`, a
+ * `relationshipsByType` bucket, and both endpoints' `edgeIdsByNode` Sets — plus
+ * an `id` that concatenates both endpoint ids. (Dropping just the two redundant
+ * indexes was measured too: 174 of 648 B/edge, ~1.3x. Not enough on its own.)
+ *
+ * Nodes are deliberately NOT streamed: they are the other 17%, and two
+ * scope-resolution index builders (`buildGraphNodeLookup`,
+ * `buildGraphCallableAnchorIndex`) scan them.
+ *
+ * ## How much this actually saves — read this before quoting a number
+ *
+ * Measured A/B against the object-based graph, 400k nodes / 1.08M edges, all
+ * edges streamable (the worst case for this design): **823 MB -> 626 MB, ~1.3x**,
+ * with all 1.08M edges still visible through `iterRelationships`.
+ *
+ * That is well short of the ~2.9x a naive `0.17 + 0.83 * 0.21` retained-share
+ * calculation suggests, and the gap is deliberate: this sink is *lossless*, so
+ * it pays for the {@link streamedIds} dedup Set (one unique id string per
+ * streamed edge) and the columns above. An earlier revision hit a bigger number
+ * by disabling community detection, process extraction and the taint fixpoint —
+ * which is why it could not be the default. 1.3x with nothing traded away is the
+ * honest figure; if a future change needs more, the next lever is dedup keyed on
+ * the interned column triple rather than on id strings (it must first be shown
+ * not to alter the emitted row SET).
+ *
+ * ## What it costs — measured, not assumed
+ *
+ * Measured on the same 400k-node / 1.08M-edge graph, all edges streamable, each
+ * arm running what its own consumers actually call:
+ *
+ *   heap  819 MB -> 584 MB   (1.40x better)
+ *   scans  ~78 ms -> ~88 ms  (parity, within run-to-run noise)
+ *
+ * Linear in both: verified at 100k/200k/400k/800k nodes, per-edge scan cost flat
+ * (~13 ns both arms) and the heap ratio drifting only 1.7x -> 1.5x as interner
+ * indices gain digits. No super-linear term, so a larger repo costs
+ * proportionally more, not disproportionately.
+ *
+ * The dedup key encodes its tail SEGMENT COUNT, which measurably costs ~66 MB
+ * here versus omitting it. That is not optional: without it a one-segment tail
+ * `:7` and a two-segment `:7:0` collapse onto one key and an edge is silently
+ * dropped (regression test in graph-emit-sink.test.ts).
+ *
+ * Getting there took three measured steps, because the naive version was 6.8x
+ * WORSE (651 ms) — reads rebuild objects, and a real analyze performs SIX full
+ * relationship scans (the pruner, community detection x2, process extraction x2,
+ * and the taint fixpoint's CALLS pass):
+ *
+ * 1. The ~150-character synthesized `id` was built eagerly on every read — 6.5M
+ *    concatenations for a field no in-pipeline consumer reads. Isolating it
+ *    showed 436 ms of the regression. It is now a lazy prototype getter on
+ *    {@link StreamedRelationship}.
+ * 2. Generator and iterator-protocol overhead: {@link forEachRelationship} loops
+ *    the columns directly, and {@link iterRelationships} reuses one
+ *    iterator-result record. Note a hand-rolled iterator allocating a fresh
+ *    `{value, done}` per edge measured WORSE (252 ms) than the generator it
+ *    replaced, so the obvious rewrite is not the one that shipped.
+ * 3. The remaining ~90 ms was object allocation itself, irreducible while the
+ *    read API returns objects — so the five whole-graph scans moved to
+ *    `forEachRelationshipFields`, which passes the four fields they actually
+ *    read as primitives and allocates nothing. See
+ *    {@link GraphEmitSink.forEachRelationshipFields}.
+ *
+ * The last allocating scan is the taint fixpoint's `iterRelationshipsByType`
+ * pass; it is one scan of six and accounts for the small residual. Give it a
+ * by-type field variant only if a measurement says it matters.
+ *
+ * It is in any case NOT O(chunk) — node identity and the resolution registries
+ * stay O(repo). True O(chunk) needs DB-side resolution and Leiden (#2337), at
+ * which point this sink should be deleted rather than extended.
+ *
+ * ## Correctness contract
+ *
+ * Structural sibling of {@link PdgEmitSink}, and reuses its row builder
+ * (`buildRelRow`), header (`REL_CSV_HEADER`) and pair classification
+ * (`relPairKeyFor`, which is also what `RelPairRouter` routes and skips by), so
+ * the streamed row SET equals the whole-graph emit's and the bulk COPY loads
+ * the same rows. Set-level, not
+ * byte-level: rows stream in emit order and are not re-sorted under
+ * `GITNEXUS_SORT_GRAPH_OUTPUT`.

+ *
+ * `Route` / `Tool` being excluded as ANCHORS (see {@link NON_DEFINITION_LABELS})
+ * is likewise a SIZE choice, not something derived from a rule: they do source

+ * The generated half of the DDL — one `  FROM \`x\` TO \`y\`` line per pair of
+ * the two cross products below.
+ *
+ * 1. SCOPE BRIDGE — `SCOPE_BRIDGE_SOURCE_LABELS × SCOPE_BRIDGE_TARGET_LABELS`.
+ *    Those sets ARE the bridge's emit surface: `buildGraphNodeLookup` holds
+ *    only `LINKABLE_LABELS`, so every id `resolveDefGraphId` returns wears one
+ *    of those labels (#2792).
+ * 2. ATTACHMENT — `DEFINITION_ANCHOR_LABELS × ATTACHMENT_TARGET_LABELS`, the
+ *    phase/framework overlays hung off a resolved anchor (#2793).
+ *
+ * Generated rather than hand-listed because in both families the endpoint
+ * labels are LOOKUP RESULTS, not literals at the emit site — so any pair drawn
+ * from the sets can reach `assertDeclaredPair`, and an undeclared one aborts
+ * `analyze` outright on whichever codebase happens to produce it. Every
+ * hand-listed fix so far declared only the pair in the stack trace and left the
+ * rest of its family missing: `Const→Method` (#2781), `Class→Variable` (#2792),
+ * `Interface→CodeElement` (#2416), then `Method→Annotation` / `Method→File` /
+ * `Namespace→Record` / `Class→Tool` (#2793) — four more from three different
+ * emitters, all live at once.
+ *
+ * A `Set` guards the emit against a DUPLICATED pair — the asymmetric failure
+ * mode `rel-pair-routing.ts` documents at length: a duplicate makes LadybugDB
+ * reject `CREATE REL TABLE` and kills EVERY `analyze`, where a missing pair only
+ * kills the codebases that emit it. The two target sets are disjoint TODAY, so
+ * nothing is deduped in practice; the Set is here so that moving one label
+ * between the rules can never cause it. Pairs already in
+ * {@link STRUCTURAL_PAIR_DDL} are skipped for the same reason.

+/**
+ * Cross-process single-writer lock for a GitNexus index directory (#2658).
+ *
+ * `analyze` is the only writer of a `.gitnexus/` (or `branches/<slug>/`) slot,
+ * but nothing stopped two `analyze` runs — e.g. two editor/agent SessionStart
+ * hooks firing on the same repo at once — from wiping and rebuilding the same
+ * store concurrently. They raced on `lbug` and its sidecars, wasted N× CPU
+ * producing one index, and left orphaned WAL fragments (#2637). This module
+ * gives the write path an exclusive, index-directory-scoped lock so a second
+ * writer waits for the first instead of colliding; after acquiring, the caller
+ * re-runs its normal freshness check, so a run whose work the holder already
+ * did exits up-to-date rather than rebuilding (single-flight coalescing).
+ *
+ * Ownership lives with the process that runs the pipeline (the heap-respawn
+ * child when a respawn happens, the original otherwise) — NOT a supervising
+ * parent — so the entity the OS tracks for liveness is always the real writer.
+ * See run-analyze.ts for the acquire site.
+ *
+ * TWO BACKENDS behind the {@link acquireIndexLock} seam:
+ *
+ *  - **socket** (Windows named pipe / Linux abstract socket, via `net`) — the
+ *    preferred, KERNEL-OWNED lock. Holding it = holding a listening endpoint the
+ *    kernel binds to this process; `EADDRINUSE` therefore means a *live* holder,
+ *    and the kernel drops the binding the instant the holder exits for ANY reason
+ *    (clean exit, crash, OOM, SIGKILL). That makes it provably race-free: no
+ *    stale detection, no pid-reuse guess, no takeover, and — since the endpoint
+ *    lives outside the index dir — no filesystem write, so it works unchanged on
+ *    a read-only index mount. This is the same class of kernel object as the
+ *    Windows named mutex the issue's reporter used as an external workaround, but
+ *    built from Node's stdlib `net`, so it adds NO native dependency and cannot
+ *    break `npx gitnexus` install anywhere.
+ *
+ *  - **file** (`O_EXCL` pidfile) — the portable fallback for macOS/BSD (no
+ *    abstract sockets; filesystem sockets don't release cleanly on death) and
+ *    for any environment where the socket backend can't bind. It uses pid-
+ *    liveness staleness, an atomic rename-steal reclaim, bounded malformed-file
+ *    handling, read-only tolerance, and a finite wait timeout (a reused pid can
+ *    masquerade as live where process start-time isn't verifiable, so waiting is
+ *    bounded rather than a hang). Its stale-takeover has an irreducible narrow
+ *    race — inherent to file-based advisory locks — which is precisely why the
+ *    socket backend is preferred; only a kernel primitive closes it.
+ *
+ * Scope: cross-process, same logical index dir. The file backend never steals a
+ * foreign-host lock (pid liveness is meaningless across hosts); the socket
+ * backend is single-host by nature. The motivating case (local hook-driven
+ * re-index) is single-host. See AcquireOptions.timeoutMs for the wait ceiling.

+// the feature/schema inventory alone cannot invalidate pre-#2413 captures.
+// (Cut as v32 on this branch; `main` took 32 for #2742 and 33/34 for #2747
+// first, so this series is renumbered at merge time — see the v21 note.)
+// v34: the receiver-chain capture is emitted by ALL 14 language emitters, not
+// just TypeScript. v33 landed with the TypeScript-only emission; the rollout to
+// the other 13 languages changed the capture set AGAIN, so a cache stamped 33 by
+// an intermediate build of that series is not equivalent to one stamped at this
+// commit — it would be treated as current while every non-TypeScript file
+// replayed pre-rollout captures, leaving the feature silently inert for 13 of 14
+// languages. Bumped there so the version tracks the FINAL capture set rather
+// than the first divergence.
+// v33: TypeScript call matches carry `@reference.receiver-chain`, a compact
+// encoding of a receiver that is itself an expression.
+// v32: Rust items are qualified by their enclosing `mod` chain (#2742). The
+// qualified name is computed in the parse worker, so a warm cache replays the
+// old unqualified ids verbatim and the collapse persists.
+// v31: Rust `mod_item` gained `@declaration.namespace` and scoped call sites
+// gained `@reference.qualified-name` (#2730). Both are PARSE-TIME captures, so a
+// warm cache replays the old capture set verbatim: `rawQualifiedName` comes back
+// undefined and no Namespace def exists to hang a module prefix on, which turns
+// the whole module-qualified resolution tier into a no-op on unchanged files.
+// Re-checked against origin/main at commit time per the v29 note below.
+// v29: closure-binding declaration rules for PHP/Rust/Kotlin/Ruby/Dart, a Rust
+// graph node for `let f = || …`, a Dart closure scope, and function-local VALUES
+// (Variable/Const/Property/Static) qualified by their enclosing callable plus
+// position (#2699 parts A1 + B). All parse-time, so a warm cache would replay
+// the old captures and the pre-qualification ids verbatim.
+//
+// This is 29 and not 28 because of the exact collision the v21 note below warns
+// about: this branch cut at 27 and bumped to 28, while #2415 bumped 27 -> 28 and
+// merged FIRST. Re-checking against origin/main at merge time — not at branch
+// time — is what caught it; leaving it at 28 would have shipped this change with
+// NO parse-cache invalidation, so every warm cache keeps serving the pre-fix
+// captures and ids.
+// v28: Java/Kotlin capture side-channels persist Spring condition facts and
+// annotation-source line numbers (#2415).
+// v26: the enclosing-callable walk stops at class bodies and anonymous-class
+// construction sites (#2699 follow-up); a v25 cache replays worker results carrying the
+// wrong Java anonymous-class ids. Cached results are replayed verbatim — including
+// across `--force` — so without this bump a warm cache keeps serving them.
+// v25: function-local callables are qualified by their enclosing-callable chain
+// plus their own position, and JS/TS gain block scopes (#2699). Both the node
+// ids AND the scope tree in a cached worker result are therefore stale. Cached
+// results are replayed verbatim — including across `--force` — so without this
+// bump a warm cache keeps serving the colliding ids and the block-less scopes.
+// v24: function scopes carry `Scope.ownsReceivers`, marking the JS/TS forms
+// that bind their own `this` (#2701). The flag lives on the cached `Scope`, so
+// without this bump a warm cache replays scopes that lack it and every `this`
+// inside an ordinary `function` keeps resolving to the enclosing class —
+// verified by probe: `--force` alone does NOT re-derive it.
+// v23: closure bindings emit callable nodes in Dart, Ruby, Java, C# and PHP
+// (plus JS/TS `var`), and Dart/PHP gain the scope declarations and flow
+// captures their forms were missing (#2693). Cached worker results are replayed
+// verbatim, so without this bump a warm cache keeps serving the old labels.
+// v22: `const X = <arrow | function-expression>` emits one `Function` node
+// instead of a `Function` plus an edgeless `Const` twin (#2687). Cached worker
+// results are replayed verbatim — including across `--force` — so without this
+// bump a warm cache keeps serving the old two-node set.
+// v21: TWO changes share this number — a collision, not a typo. #2632
+// (Java/Kotlin Spring DI facts: constructor, field/property and method
+// injection sites plus bean-name and @Primary provider metadata) bumped 20 -> 21
+// and merged first; #2653 (Java local class/enum/record/interface captures using
+// javac-compatible, source-type-relative JLS 13.1 identities and
+// declaration-to-block scopes, #2562) had branched at 20, bumped to 21 as well,
+// and merged second — so it shipped with NO invalidation of its own. An index
+// already stamped 21 by the first change was treated as current by the second
+// and kept serving stale local-class identities from the warm cache. Harmless
+// now (anything below the current value is rejected), and left as-is because
+// both genuinely shipped as 21 — renumbering would misstate history. Read this
+// as the reason to re-check SCHEMA_BUMP against origin/main immediately before
+// merging, not just when the branch is cut; the same collision hit
+// INCREMENTAL_SCHEMA_VERSION in #2653/#2654.
+// v27: generator EXPRESSIONS bound to a name emit a callable definition capture,
+// and nested-callable caller attribution appends the localIdentity suffix the
+// definition phase already used. Both are parse-time, so a warm cache would
+// otherwise replay the old captures and ids verbatim.
+// v30/schema v22: CommonJS export capture emission (#2723) — new @definition/@declaration
+// captures for exports.X, aliased receivers, module-level `this`, re-export
+// forwarding and `module.exports = fn`, plus prototype/`this` Methods. A warm
+// cache would otherwise replay the pre-fix captures verbatim.
 // v20: Java/Kotlin capture side-channels persist package and class-annotation
 // facts for shared Spring Bean resolution.
 // v19: Java enum constant bodies emit E$N Class nodes; anonymous naming uses
 // JLS 13.1 immediate-host chains (#2555).
 // v18: Worker$N anonymous bodies. v17: callable-value-flow operand identity.
 // v16: direct callee identity.

+// v36: bound-callable graph `startLine` follows the initializer so multi-line

+// v37: Java/Kotlin capture side-channels include Spring AOP owner/advice facts
+// (#2416). Warm cache entries at v36 do not carry those facts and would silently
+// omit ADVISED_BY evidence.
+// v38: Swift nested conditional-compilation directives are blanked before the
+// parse (#2771), so a class body that previously error-recovered away now
+// survives. The chunk key hashes raw on-disk bytes and `preprocessSource` runs
+// after it is computed, so unchanged Swift files would otherwise replay their
+// pre-fix `ParseWorkerResult` verbatim — including across `--force`. Allocated
+// on `main`, NOT by this branch — kept so the number is not reused a third time.
+// v39: receiver-chain wire format v2 — the encoded chain gained name-free
+// `await` and `index` step kinds, so the VERSION prefix moved 1 -> 2 and every
+// persisted chain string changed. A v2 decoder REFUSES a v1 payload (that is
+// the point: a chain missing its await or index hop decodes cleanly as a
+// different, shorter chain and would type the receiver against the wrong
+// member), so a stale cache replays chains this build silently discards —
+// the feature degrades to the text cascade with no error anywhere. Bumped so
+// the stale cache is rejected rather than half-read.
+//
+// NUMBERED 39, AFTER TWO REALLOCATIONS. This branch first used 37; `main` took

+// incompatible schemas claiming one number, twice running. The lesson is not

+ * v14: C# and Kotlin free-call fallback now rejects same-file methods whose

+ * 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.
+ *
+ * (This shipped as v25 on its own branch; `main` took 25 through 28 first, so it
+ * is renumbered at merge time. Re-check both constants against origin/main
+ * immediately before merging — this is the fifth time that collision has bitten.)
+ *
+ * v26: unresolved-receiver member names are persisted
+ * (`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.

+/**
+ * #2699 — JS/TS `statement_block` scopes, and the false ACCESSES edges they
+ * remove.
+ *
+ * Enabling `(statement_block) @scope.block` for TS/JS dropped 114 ACCESSES
+ * edges across a 762-file corpus with `added: 0`. That looked like a
+ * regression, so it was measured rather than assumed: all 274 emitting
+ * reference sites behind those 114 edges were classified by re-reading the
+ * source at the site. Every one of the 114 had at least one site of the form
+ * `receiver.name`, and none was bare-identifier-only. (269 sites classified as
+ * member reads outright; the 5 remaining were classifier artifacts — the name
+ * also occurred earlier on the line, as in `a.b.declLine` for `b` — and are
+ * member reads too.) So every dropped edge was a PROPERTY read
+ * (`options.baseUrl`) mis-resolving to an unrelated function-local `const` of
+ * the same name in the same file.
+ *
+ * The cause was not block-specific: `lookupCore` Step 1 walked the lexical
+ * chain for EVERY lookup, including explicit-receiver property reads, so
+ * `options.baseUrl` could bind to a local `baseUrl`. Block scopes narrowed
+ * that — they moved a nested-block local off the chain of any reference
+ * outside its block — but a local declared directly in the FUNCTION BODY
+ * stayed on it, and no amount of extra scopes reaches that case.
+ *
+ * That residual half is fixed here too: Step 1 is now skipped when the site
+ * has a NAMED explicit receiver, since `recv.name` addresses a member of
+ * whatever `recv` denotes and never a lexical binding of the bare tail name.
+ * The second describe below pins it. What remains, deliberately, is that a
+ * `this`/`self` read can still bind lexically to a same-named local — that is
+ * the price of keeping the genuine self-alias reads Step 1 resolves correctly
+ * (`const self = this; self.member`), which is why those two names are exempt.
+ *
+ * So these tests pin the change in BOTH directions: a property read must not
+ * reach a same-named local, and a real member read must still resolve through
+ * the receiver's own type. Deleting the block-scope capture fails the first;
+ * over-suppressing — dropping block bindings rather than scoping them, or
+ * skipping Step 1 for `this` as well — fails the second.

+/**
+ * #2687 follow-up — a closure bound to a name emits ONE `Function` node in
+ * every language, not `Variable` in some and `Property` in others.
+ *
+ * `const f = () => {}` already produced a `Function` in TS/JS (that is what the
+ * #2687 twin fix preserved), but the same construct produced a `Variable` in
+ * Go/Python/Dart/C++ and a `Property` in Kotlin/Swift. The graph schema states
+ * "Function: Functions and arrow functions", and every syntactic tagger the
+ * convention was checked against (tree-sitter tags, universal-ctags) labels the
+ * binding a function — so the callable label is the consistent one.
+ *
+ * Each language's value capture still matches the same declaration node, so
+ * these rely on the #2687 pre-scan collapsing the pair; a regression there
+ * would surface here as a twin rather than a wrong label.
+ *
+ * The label alone does not make `f()` resolve. Go, Python and C++ carry a
+ * `@declaration.function` capture anchored on the inner closure literal, so
+ * free-call resolution finds the def directly. Kotlin, Swift and Dart cannot
+ * take that route — they lack a `@scope.function` whose range matches the
+ * closure literal (Kotlin deliberately scopes `lambda_literal` as a BLOCK,
+ * #1757) and an unaligned declaration anchor mis-attributes callers.
+ *
+ * #2693 resolves those three through `callable-value-flow` instead: the graph
+ * node this file asserts IS the evidence that admits the binding as a callable
+ * target, so a regression in the labels above now also breaks call resolution.

+ * top-level `impactedCount: 0` — indistinguishable from a real "nothing depends

+ *
+ * Root cause: the parse-worker duplicate suppression is order-dependent. Only

+ * `processedDefinitionNodes`; function-like labels merely register into it. And
+ * tree-sitter yields the `@definition.const` match BEFORE `@definition.function`
+ * for the same `lexical_declaration` (the const pattern completes at `@name`,
+ * the function pattern needs the trailing arrow/function-expression value), so
+ * the twin was emitted first and never suppressed.
+ *
+ * The over-suppression guards below matter as much as the twin assertions: a
+ * genuine non-callable `const`, an object-literal service (#1718), a plain
+ * `var` value, and the non-function initializers must all keep their value

+/**
+ * #2699 — a function-local callable gets its own graph node instead of
+ * collapsing onto a same-named file-level one.
+ *
+ * Graph node ids are file-scoped, so before this a top-level `save()` and a
+ * local `const save = …` inside `run()` both keyed `Function:<file>:save`. That
+ * is a WRONG answer, not merely a missing one: `run`'s call to its own local
+ * was attributed to the top-level function, so `impact` on `save` reported a
+ * caller that never calls it.
+ *
+ * A local's identity is its enclosing-callable chain plus its own position —
+ * `run.save@2:2`. The chain is for humans reading `impact` output; the position
+ * is what makes it correct. ECMAScript creates an environment record per
+ * function AND per block, so a name alone cannot separate sibling blocks, and
+ * an anonymous function has no name to contribute at all. Position settles both
+ * (SCIP reaches the same place with its document-scoped `local <id>`).
+ * Top-level functions and class methods are NOT locals and keep their existing
+ * ids — that is the bound on how far this churn reaches.
+ *
+ * THE SILENT FAILURE THIS GUARDS. Node ids are built twice and independently:
+ * once by the definition phase and once by the caller-attribution phase
+ * (`findEnclosingFunctionId`). If those two disagree by a single character the
+ * caller attaches to a node that does not exist and the edge simply vanishes —
+ * nothing throws, and a test that only checked "the node exists" would still
+ * pass. Every assertion here is therefore on the EDGE, whose source and target
+ * are produced by the two different phases: it can only pass if both agree.

+/**
+ * Spring standard-DI scaling benchmark (#2414 / PR #2632 review).
+ *
+ * Guards the two hot paths introduced by standard Spring injection:
+ *
+ *   1. Java and Kotlin capture emission collect DI facts from their existing
+ *      scope-query traversals instead of recursively walking the AST root a
+ *      second time.
+ *   2. Post-resolution metadata attachment finds captured fields through the
+ *      owning class scope's bindings instead of scanning every HAS_PROPERTY
+ *      relationship in the graph.
+ *
+ * The normal-CI tripwires use dense Java/Kotlin files to catch a capture
+ * re-regression. The gated suites measure Java and Kotlin capture plus
+ * full-pipeline scaling:

+/**
+ * Corpus-derived coverage for the HAND-DECLARED half of `RELATION_SCHEMA`.
+ *
+ * `test/unit/schema-pair-coverage.test.ts` derives its requirement from
+ * schema.ts's two rules — the scope-resolution bridge cross product, and
+ * `DEFINITION_ANCHOR_LABELS × ATTACHMENT_TARGET_LABELS` for the framework and
+ * pipeline-phase overlays — so both generated halves are covered there. What
+ * neither rule can reach is `STRUCTURAL_PAIR_DDL`: the containment, inheritance
+ * and import pairs BETWEEN TWO DEFINITION LABELS. Eleven node tables are absent
+ * from every rule's target side (`CodeElement`, `Impl`, `Namespace`,
+ * `Template`, `TypeAlias`, `Typedef`, `Union`, `Static`, `Section`, `Folder`,
+ * and the PDG-only `BasicBlock`), so a pair pointing at one is hand-declared or
+ * it does not exist. No predicate describes that surface — any container can
+ * hold any definition — so this asks the emitters directly: run the real
+ * pipeline and require every FROM/TO pair it produces to be declared.
+ *
+ * Each entry also pins the pair it exists to guard. Without that the suite is
+ * vacuous: `undeclared` is derived from what the pipeline emitted, so a fixture
+ * that stopped emitting — renamed directory, grammar that failed to load,
+ * swallowed parse error — yields an empty set and passes green while guarding
+ * nothing. `sentinels` turns each case from "nothing undeclared" into "this
+ * emitter still fires, and everything it emits is declared".
+ *
+ * Coverage is bounded by `NON_BRIDGE_CORPUS`: a sample, not a proof. A
+ * language whose fixture is absent is unguarded, so a new structural emitter
+ * should land with an entry here.
+ *
+ * Deliberately isolated from the resolver suites that already build three of
+ * these graphs (`resolvers/cobol.test.ts`, `resolvers/vue.test.ts`,

+/**
+ * #2701 — `this` inside an ordinary JS/TS `function` is NOT the enclosing
+ * instance, so `this.m()` there must not emit a `CALLS` edge to the enclosing
+ * class's member. Only an arrow inherits `this`.
+ *
+ * ECMA-262 gives an arrow `[[ThisMode]] = lexical`: it has no `this` binding in
+ * its environment record, so the lookup passes through to the enclosing
+ * environment. Every other function form binds `this` at call time. `tsc` draws
+ * the same line by resolving `this` through `getThisContainer` with
+ * `includeArrowFunctions = false`.
+ *
+ * The fix spans three layers. An earlier version of this comment claimed all
+ * three were independently load-bearing because "the false edge survived
+ * removing any one of them alone". That was measured DURING development and is
+ * FALSE for the shipped code — it was carried into the final commit without
+ * being re-tested. Corrected:
+ *
+ *   1. `Scope.ownsReceivers`, set from the `@receiver-owner.this` query marker,
+ *      stops both receiver-type walks (`findReceiverTypeBinding` in ingestion,
+ *      `lookupReceiverType` in gitnexus-shared's `lookup-core`).
+ *   2. `LanguageTypeConfig.thisBoundaryNodeTypes` stops the type-env AST walk
+ *      that infers a receiver's type during capture.
+ *   3. `isReceiverOwnedButUnbound` makes `receiver-bound-calls` SUPPRESS the
+ *      site. This is the one that decides the outcome for the fixtures below:
+ *      without it the member still resolved by NAME through `lookupCore`'s
+ *      lexical chain — the class-body scope binds `m`, two scopes up.
+ *
+ * Layer 3 runs FIRST (`emitReceiverBoundCalls` marks the site in `handledSites`,
+ * which `emitReferencesViaLookup` then skips), so it SUBSUMES layer 1 for an
+ * explicit `this` receiver. Removing layer 1's gate in `lookup-core.ts` leaves
+ * every test in this file passing — verified by experiment.
+ *
+ * That gate is nonetheless RETAINED, and deleting it would be a mistake: the
+ * `receiver-bound-calls` suppression only covers EXPLICIT receivers
+ * (`if (site.explicitReceiver === undefined) continue;`), while `lookup-core`'s
+ * gate is also reached for IMPLICIT ones via `IMPLICIT_RECEIVERS` in
+ * `resolveReceiverOwner` — a bare `m()` inside a nested `function` inside a
+ * method. The experiment above establishes that gate is UNTESTED, not that it is
+ * unreachable. It needs a test for the implicit-receiver path; until then, do
+ * not treat its removability as demonstrated.
+ *
+ * WHAT THIS DELIBERATELY GIVES UP. `.bind(this)`, `.call(this)` and
+ * `forEach(fn, thisArg)` DO make `this` the instance at runtime; their edges
+ * were correct and are now dropped. Their correctness is fixed at the call
+ * site, which a scope-level rule cannot see, so the choice is between losing
+ * them and keeping every detached-callback false positive. The pinned cases at
+ * the bottom record that trade so a future change to it is deliberate.

+ * Tests for the undeclared FROM→TO label-pair failure path in the

+ *
+ * `assertDeclaredPair` aborts the run when an extracted edge's endpoint-label
+ * pair is missing from GitNexus's own relation DDL — deliberately, because the
+ * alternative is a late `COPY` failure that silently drops edges. Before this
+ * branch existed the user got `Analysis failed` plus a stack trace through
+ * GitNexus internals: no file, no relationship, and an implicit "try again"
+ * that can never work. The CLI must instead name the pair, the relationship
+ * type and the offending file, and point at an issue report.
+ *
+ * The CLI does NOT compose that text: it prints `err.message` indented (the
+ * `LbugWipeError` idiom in the same catch block), because the message is
+ * self-contained — `gitnexus serve` forwards only `err.message` over worker
+ * IPC, so anything rendered here instead would be invisible to serve users.
+ * The needles below are therefore the SAME strings
+ * `test/unit/rel-pair-routing.test.ts` pins on the message itself.
+ *
+ * Mirrors analyze-http-endpoint-error.test.ts:
+ *   - vi.mock the heavy dependencies so no real DB / git is touched
+ *   - drive `analyzeCommand` with a mocked `runFullAnalysis` that rejects
+ *   - assert on process.exitCode and the captured logger records

+/**
+ * #2699 / #2714 — the nested-callable id rule has ONE definition.
+ *
+ * Three phases in `parse-worker.ts` build the id of a callable nested inside
+ * another callable, independently: the definition phase
+ * (`callableOwnQualifiedName`), the caller-attribution phase
+ * (`findEnclosingFunctionId`), and the worker-path node-id derivation in
+ * `processFileGroup`. They must agree byte-for-byte, and when they do not the
+ * failure is SILENT — the caller id names a node that does not exist, so the
+ * edge is dropped rather than reported. "Zero dangling edges" is what that
+ * looks like from the outside, which is why it went unnoticed.
+ *
+ * Caller attribution really did omit the position suffix until #2714. The fix
+ * routed all three through `nestedCallableQualifiedName`; this file pins both
+ * halves of that — the rule's contract, and the fact that no call site has
+ * re-inlined it.
+ *
+ * The rule reads only `startPosition` off the node, so a positional stub is a
+ * complete input here; parsing real source would add a tree-sitter dependency
+ * without testing anything more of this function.
+ *
+ * The rules live in `callable-id.ts` rather than `parse-worker.ts` precisely so
+ * this file can exist: parse-worker posts a `ready` message to `parentPort` at
+ * import, so value-importing it from a unit test throws before any test runs.

+/**
+ * #2667 — a `\\?\`-prefixed path must still find its registry entry.
+ *
+ * This is the Linux-runnable guard for the `canonicalizePath` wiring. The
+ * companion assertions in `repo-manager.test.ts` exercise the real
+ * `realpathSync.native` and are therefore `it.skipIf(win32)`, so they only run on
+ * the windows-latest matrix leg — leaving the Ubuntu gate with no coverage of the
+ * behaviour at all. This file closes that hole by injecting the two platform
+ * primitives and nothing else:
+ *
+ *   - `path` → `path.win32`, which is Node's real Windows path implementation,
+ *     not a stand-in for it;
+ *   - `realpathSync.native` → its two actual Windows behaviours: for a path that
+ *     is on disk libuv's `fs__realpath_handle` strips `\\?\` before returning,
+ *     and for a path that is not it throws ENOENT;
+ *   - `stripWindowsLongPathPrefix` → the real implementation, pinned to `'win32'`
+ *     instead of defaulting to `process.platform`.
+ *
+ * That last one is deliberately a module mock rather than an
+ * `Object.defineProperty(process, 'platform', …)`: module mocks are scoped to this
+ * file, whereas `process` is shared by every test file in the same worker, so
+ * overriding it risks a sibling that branches on the host platform.
+ *
+ * `canonicalizePath` and `registryPathEquals` themselves run unmodified. Run
+ * against the pre-fix tree (89bbdcf5) the two `catch`-fallback cases below fail
+ * and the realpath case passes, which is exactly the asymmetry the fix targets:
+ * the realpath branch never leaked, because libuv strips the prefix itself.
+ *
+ * Deliberately NOT registered in `scripts/cross-platform-tests.ts`: it simulates
+ * Windows rather than needing it, so its home is the Ubuntu suite.

+ * #2699 consumer audit — `detect_changes` must not key on node ids.
+ *
+ * #2695/#2714 gave function-local CALLABLES position-bearing ids
+ * (`Function:x.ts:run.save@3:2`). That raised a specific worry for this
+ * consumer: an id containing `@row:col` changes whenever the declaration
+ * MOVES, even when the code is byte-identical, so an id-keyed
+ * `detect_changes` would report churn for every edit above a local.
+ *
+ * The worry is unfounded, and this file pins why. `detect_changes` maps diff
+ * hunks to symbols by LINE-RANGE OVERLAP — it matches `n.startLine`/`n.endLine`
+ * against the hunk bounds and merely REPORTS `n.id`. Node identity never
+ * participates in the match, so a position-bearing id cannot inflate
+ * `changed_count`.
+ *
+ * These are structural (source-grep) assertions, in the same idiom as
+ * `detect-changes-worktree.test.ts`: they prove the query still has the shape
+ * the audit verified, and would fail loudly if someone switched the mapping to
+ * id equality. They do NOT execute the query — the behavioural coverage for
+ * detect_changes lives in the MCP integration suites.

+/**
+ * #2787 structural guard — a Cypher `LIMIT` must DECLARE its determinism.
+ *
+ * LadybugDB/Kuzu returns an ARBITRARY, per-process-varying row subset when a
+ * query carries `LIMIT` without `ORDER BY`. #2787 swept ~20 such queries, but a
+ * sweep does not stop the 21st: the only surviving guard was one runtime test
+ * that captured emitted SQL on a single tool path.
+ *
+ * "Is this `LIMIT` a sampling window or a probe?" cannot be INFERRED from the
+ * text — a `LIMIT 1` on a primary-key anchor is provably single-row, and a
+ * `LIMIT 30` on a fan-out is a silent lottery, and they look identical. So this
+ * gate does not infer. It makes the author DECLARE, once, at the call site:
+ *
+ *   1. ORDER the query — the literal contains `ORDER BY`, or interpolates a
+ *      constant/helper that does (e.g. `${DETERMINISTIC_RELATIONSHIP_ORDER}` in
+ *      `mcp/local/aop-metadata.ts`, which a naive text scan would miss); or
+ *   2. DECLARE it a probe — an adjacent comment in the canonical form
+ *
+ *        // determinism: probe — <why row identity cannot vary>
+ *
+ *      The reason is mandatory and validated (>= 20 chars, >= 3 words): an
+ *      empty or one-word marker fails exactly like an undeclared query.
+ *
+ * There is deliberately NO allowlist file. A hand-maintained list drifts from
+ * the code and puts the justification somewhere the next author will not read;
+ * the declaration lives beside the query it defends.
+ *
+ * ── How the two known false verdicts are avoided ──────────────────────────
+ *
+ * FALSE NEGATIVE (interpolated ordering): the scan is AST-based, so a
+ * `TemplateExpression` is taken WHOLE (`${...}` included) and every interpolated
+ * identifier is resolved against the file's own string constants / helper
+ * functions, transitively. `${DETERMINISTIC_RELATIONSHIP_ORDER}` counts as
+ * ordered without the constant's text appearing in the query literal.
+ *
+ * FALSE POSITIVE (prose): comments and JSDoc are not literal nodes, so prose
+ * like "the page is `LIMIT`-bounded" (several places in `mcp/local/`) is never
+ * a query. Same for `LIMIT` inside a regex literal (`cobol-preprocessor.ts`)
+ * and inside identifiers (`LIST_REPOS_MAX_LIMIT` — `\bLIMIT\b` needs a word
+ * boundary, and `_` is a word character).
+ *
+ * Also handled: interpolated limits (`LIMIT ${rowCap}`), multi-line template
+ * literals, and `+`-concatenated queries (the concatenation is one unit, so an
+ * `ORDER BY` in an earlier fragment still counts).
+ *
+ * Prior art for this source-scanning shape: `local-backend-maxbuffer.test.ts`
+ * and `detect-changes-local-id-stability.test.ts`.

+/**
+ * The drift guard for the implicit-receiver twin lists (#2699 follow-up).
+ *
+ * TWO lists spell "this is an implicit receiver", in two packages:
+ *
+ *   - `IMPLICIT_RECEIVERS` — gitnexus-shared `lookup-core.ts`. Two consumers:
+ *     the Step-1 lexical skip (a NAMED receiver must not resolve its member
+ *     through the lexical chain) and `resolveReceiverOwner`.
+ *   - `THIS_RECEIVERS` — gitnexus `type-env.ts`. Decides whether a receiver
+ *     rewrites to the enclosing type.
+ *
+ * They are the SIXTH twin-list instance found in this family of work, and the
+ * previous five each shipped a bug when one side moved. `$this` was added to
+ * the shared list in #2714 precisely because it was already in the other one;
+ * nothing but this test stops the next divergence.
+ *
+ * `Me` is the one deliberate asymmetry: `THIS_RECEIVERS` carries it (Visual
+ * Basic spelling) and the shared list does not, because no entry in
+ * `SupportedLanguages` uses it — mirroring it there could only ever exempt a
+ * variable that happens to be named `Me`. That exemption is asserted
+ * explicitly rather than tolerated, so RE-adding `Me` to the shared list, or
+ * dropping it from the local one, both fail loudly.
+ *
+ * Structural (source-parsed) rather than value-imported: both constants are
+ * module-private, and exporting them purely to be testable would widen two
+ * public surfaces to satisfy a test. Same idiom as
+ * `detect-changes-local-id-stability.test.ts`.

+/**
+ * ── #2790 review: the four P1s the first cut left behind ───────────────
+ *
+ * Everything above proves Phase 5 reasons correctly once it is REACHED and
+ * once the count probe answers honestly. These prove the four ways it was not:
+ *
+ *  1. the mid-run `onCheckpoint` count query ran bare — a throw there rejected
+ *     the callback, propagated out of `runEmbeddingPipeline` and killed the run
+ *     before Phase 5 executed at all, so the tri-state could never fire;
+ *  2. Phase 5's hand-copied count body ended `?? 0` where the server's ended
+ *     `?? Number.NaN`, so a NO-ROW answer became a MEASURED zero and the gate
+ *     threw on runs where every embedding persisted;
+ *  4. the unknown-count fallback read `existingMeta` — a run-START snapshot —
+ *     and clobbered the fresher count this run's own checkpoint had written;
+ *  5. an exit-0 partial run planted a checkpoint stamped with this run's
+ *     embedding identity that a later plain `analyze` could not resume, could
+ *     not clear, and died on before any phase ran.
+ *
+ * Driven on the same wholesale-mock harness, with MUTABLE controls so one mock
+ * set can drive a multi-run scenario (a checkpoint's whole point is what the
+ * NEXT run does with it).

+ * `analyze` dies mid-phase on whichever codebase first produces it. Failing
+ * here means fixing the rule, not the assertion.
+ *
+ * WHAT SCHEMA.TS NO LONGER RISKS. The DDL used to carry hand-copied twins of
+ * `LINKABLE_LABELS` / `CALL_TARGET_TYPES`. Those are deleted — schema.ts now
+ * imports the originals — so two whole failure modes are structurally
+ * impossible rather than merely asserted: a label present only in the twin, and
+ * a label removed from the original while the DDL keeps its pairs. Neither was
+ * catchable before (a twin-only `Class|Record` left every assertion green).
+ *
+ * WHAT STILL NEEDS ASSERTING, and is:
+ *  - the rules themselves — the constants below are a deliberate PIN of
+ *    schema.ts's two rules, recomputed here from `LINKABLE_LABELS`,
+ *    `CALL_TARGET_TYPES` and `NODE_TABLES`. Widening a rule in schema.ts alone
+ *    fails `generated region matches …`, so the widening has to be stated
+ *    twice, on purpose.
+ *  - the generated region for EXACT equality, not containment — so a pair
+ *    hand-added to the generated half (the reflex that produced #2781, #2792
+ *    and #2793) fails just as loudly as a missing one.
+ *  - `STRUCTURAL_PAIR_DDL` carrying nothing a rule already generates. Every
+ *    other assertion here subtracts `structural` from BOTH sides, so a
+ *    redundant hand-declaration was invisible to all of them; `no hand-declared
+ *    pair …` below is the one that sees it.
+ *
+ * WHAT THIS FILE CANNOT SEE: a pair hand-added to {@link STRUCTURAL_PAIR_DDL}
+ * that NEITHER rule covers — the ~72 containment/inheritance/import pairs
+ * between two definition labels. That surface has no predicate, so it is
+ * bounded by a corpus instead, in

+ * its next `analyze`.
+ *
+ * The seam: mock `runPipelineFromRepo` so it records the `PipelineOptions` the
+ * orchestrator actually built and then rejects. That asserts the real wiring
+ * (`streamGraphEmit` + `graphEmitCsvDir` as handed to the pipeline) rather than
+ * re-testing the pure resolver, which `stream-graph-emit-config.test.ts`
+ * already covers. Everything after the pipeline call is out of scope, so the

+/**
+ * #2701 / #2699 follow-up — the TS/JS function node-type lists must agree with
+ * the queries that produce them.
+ *
+ * Four lists describe "which node types are function-like", maintained by hand
+ * in four files:
+ *
+ *   1. `query.ts`      — the `@scope.function` / `@receiver-owner.this`
+ *                        patterns (what becomes a scope, and which scopes bind
+ *                        their own `this`)
+ *   2. `captures.ts`   — `FUNCTION_NODE_TYPES`, which feeds `functionNodeTypes`
+ *                        into callable-flow capture synthesis AND the
+ *                        body-block filter
+ *   3. `receiver-binding.ts` — `THIS_REBINDING_BOUNDARY_TYPES`, where the
+ *                        enclosing-type walk stops
+ *   4. `type-extractors/typescript.ts` — `THIS_BOUNDARY_NODE_TYPES`, where the
+ *                        type-env AST walk stops. Its own docstring already
+ *                        claims it is "kept in sync with `@receiver-owner.this`
+ *                        in query.ts" — this test is what makes that true.
+ *
+ * Drift between them is silent — it produces wrong edges, not errors. Real
+ * instance: `generator_function` (the EXPRESSION form, `const g = function* ()
+ * {}`) was added to both queries for #2701 and is present in both `this`-
+ * boundary lists, but was missing from both `FUNCTION_NODE_TYPES`.
+ *
+ * That particular gap was measured to change no graph output today — the
+ * `this` boundary was already correct via the query marker, and a
+ * generator-expression binding emits a `Const` node, so its call does not
+ * resolve either way. So this test is not backfilling a live bug; it is
+ * removing the class of bug, which the four-way hand-sync otherwise makes a
+ * matter of vigilance. It fails on that drift, which is the point.
+ *
+ * Lists 1 and 2 are asserted EQUAL. Lists 3 and 4 are asserted as subsets with
+ * an explicit allowlist, because they encode a different question: a
+ * `method_definition` binds its own `this` (so it is marked in the query) but
+ * the class IS its `this`-owner (so neither walk may stop there).
