 ## Editing

 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.

 # GitNexus — Code Intelligence

-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.
+This project is indexed by GitNexus as **GitNexus** (20319 symbols, 54304 relationships, 300 execution flows). Use the GitNexus MCP 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.** 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 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 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 before MCP/CLI impact analysis.
+- NEVER edit a function, class, or method without first running `impact` on it.
 - 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 before MCP/CLI graph change analysis.
+- NEVER commit changes without running `detect_changes()` to check affected scope.

 `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:

 4. **Timing** — per-phase `durationMs` in `PhaseResult`, dev-mode console logging.

 **Design patterns:**
-
 - **Single graph accumulator** — all phases mutate the same `KnowledgeGraph` in `ctx`; the graph is the primary output.

 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).

 ### Chunked parse-and-resolve

 `parse` processes files in ~20 MB byte-budget chunks to bound memory. Per chunk:
-
 1. Worker pool dispatches files (the sole parse path — there is no sequential fallback; `skipWorkers`, `--workers 0`, and `GITNEXUS_WORKER_POOL_SIZE=0` are rejected with an actionable error)
 2. Each worker: detect language → load grammar → run queries → return unified `ParseWorkerResult`

 Inheritance is captured by the `@reference.inherits` tag and emitted by the scope-resolution phase: `preEmitInheritanceEdges` resolves each base in scope, then `emitHeritageEdges` writes the `EXTENDS`/`IMPLEMENTS` edges.

+This project is indexed by GitNexus as **GitNexus** (20319 symbols, 54304 relationships, 300 execution flows). Use the GitNexus MCP 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.** 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 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 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 before MCP/CLI impact analysis.
+- NEVER edit a function, class, or method without first running `impact` on it.
 - 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 before MCP/CLI graph change analysis.
+- NEVER commit changes without running `detect_changes()` to check affected scope.

 5. **Preserve embeddings** — plain `npx gitnexus analyze` now preserves any embeddings recorded in the index metadata (`.gitnexus/gitnexus.json`, mirrored to the legacy `meta.json`) — the previous behavior wiped them. Use `--embeddings` to also generate vectors for new/changed nodes; use `--drop-embeddings` only when an explicit wipe is intended (e.g., model swap).
-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.

Check the analyze log for a `Warning: could not load cached embeddings` line — if present, the cache restore failed (corrupt DB / schema mismatch) and the rebuild had nothing to preserve. If you intentionally passed `--drop-embeddings`, this is expected.
- **Why:** Plain `analyze` preserves prior vectors by re-inserting them after the rebuild; ways to end up at zero include an explicit `--drop-embeddings`, a cache-load failure (now logged), or a model/dimension change that invalidates the cache — but zero is no longer the only embedding-loss signature to watch for; see the Sign below for the non-zero, partial-failure case.

- **Trigger:** `npx gitnexus status` reports `incompleteReasons: ["embedding-checkpoint-pending"]` (or the human-readable "Index incomplete reasons" line); `stats.embeddings` is honest and **non-zero**, and the preceding analyze log showed a `Warning: N node(s) lost their embeddings to embedding-endpoint failures` line (#2790).
- **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.

 ### Do I need to migrate?

 **Probably not, but check for assumptions.** Callers that unconditionally

-
-## 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.
-
-## `schemaVersion` → `schemaFingerprint` (issue #2798)
-
-The field that decides whether an existing index can be reused changed in
-`.gitnexus/gitnexus.json` (and in each `branches/<slug>/gitnexus.json`):
-`schemaVersion?: number` has been removed and `schemaFingerprint?: string`
-added. The new value is a 12-character digest of the graph DDL this build
-creates, so it *describes* the schema an index's tables were actually built
-from rather than asserting a number about it.
-
-An absent fingerprint is treated as a mismatch, and that is the whole
-backward-compatibility story: every index written by an earlier GitNexus
-carries no fingerprint, so it is rebuilt exactly once.
-
-### Do I need to migrate?
-
-**No.** There is nothing to run, edit, or pass. The first `analyze` after
-upgrading logs one line —
-
-```
-index schema changed (built by an unidentified GitNexus build, this build is <fingerprint>); forcing a full re-analyze so the database is recreated from the current schema.
-```
-
-— and then performs that full re-analyze itself. The same run stamps the
-fingerprint, and every run after it takes the normal incremental path again.
-
-### What happens on re-index?
-
-One automatic full re-analyze, once per index. Nothing else changes; the
-resulting graph is what the current build would have produced anyway.
-
-The scope of that one-time cost is worth knowing before you hit it. It is
-per **index**, not per machine or per repository — branch-scoped index slots
-(#2106) each keep their own `gitnexus.json`, so every slot pays for itself
-the first time it is analyzed after the upgrade. On a very large repository
-a full re-analyze is substantial, not a blip; plan the first post-upgrade
-run accordingly.
-
-### Why a digest instead of a version number?
-
-`schemaVersion` was hand-incremented, and it had to predict something a
-number cannot know: whether the DDL an on-disk database was created from
-matches this build's. It collided with `main` eight times, twice *exactly* —
-and an exact clash was the quiet failure. Two builds stamp the same number
-over different DDL, the strict `===` reuse gate reads the index as current,
-the `CREATE … TABLE` statements are skipped as "already exists", and edges
-whose endpoint pair the live database cannot persist are dropped. A wrong
-graph, with no error anywhere.
-
-A derived digest cannot fail that way: two builds agree exactly when their
-DDL agrees, so concurrent branches never need renumbering and a mismatch is
-always a real mismatch. The retired ladder's per-version rationale (v2
-`BasicBlock.callees` through v35's generated relation cross-product) now
-lives only in git history:
-`git show 561f913a3:gitnexus/src/storage/repo-manager.ts`.
-
-### What about rollback?
-
-Downgrading to an older GitNexus is safe. The older binary looks for
-`schemaVersion`, does not find one, treats the index as pre-versioning, and
-forces its own full rebuild — the same one-time cost in the other direction,
-never a stale or mismatched graph.
-
-### What if I alternate between an old and a new binary?
-
-Every switch forces a rebuild. The end-of-run metadata is written as a fresh
-object literal rather than merged over the previous file, so a new build's
-write drops `schemaVersion` and an old build's write drops
-`schemaFingerprint` — neither field survives the other's run, and each binary
-then finds its own gate unsatisfied. This hits anyone running a pinned
-`npx gitnexus@<version>` alongside a local build, or an editor hook still on
-an older release. It is a cost, not a correctness problem: each run rebuilds
-against its own schema, and the graph it serves is correct for the binary
-that produced it. Pin one version per index to avoid the churn.

-**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.

 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.

 `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.

- * binds its members — whereas for a named receiver they never do.
- *
- * `$this` is matched because the receiver name arrives as the reference node's
- * RAW SOURCE TEXT (`extractExplicitReceiver` returns `cap.text` verbatim), so
- * PHP's `$this->x` presents as `"$this"`, sigil included. Listing the spelling
- * keeps this a data table rather than a language switch — this module resolves
- * language behaviour through `providers.*` and `params` only (see the header)
- * — and it follows the ingestion-side twin, `THIS_RECEIVERS` in
- * `gitnexus/src/core/ingestion/type-env.ts`, which has always listed the
- * sigil'd spelling rather than stripping it. Stripping would carry the same
- * false-positive surface anyway (a JS variable literally named `$this`).
- *
- * That twin also lists `Me`, deliberately NOT mirrored here: no entry in
- * `SupportedLanguages` uses it, so it can only ever exempt a variable that
- * happens to be called `Me`. The two lists are otherwise the same set, and
- * that equality — plus the `Me` exemption in both directions — is now ENFORCED
- * by `gitnexus/test/unit/receiver-twin-list-drift.test.ts`. Editing either list

 ### Experimental community detection engine

-> **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 test the #2337 Icebug migration path without changing default analyze behavior, set:

 ```bash
-npm i @ladybugmem/icebug
 GITNEXUS_COMMUNITY_ENGINE=icebug npx gitnexus analyze
 ```

-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.
+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.

-## 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

 ## Multi-Repo Support

 GitNexus supports indexing multiple repositories. Each `gitnexus analyze` registers the repo in a global registry (`~/.gitnexus/registry.json`). The MCP server serves all indexed repos automatically.

 ### Installation fails with native module errors

 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.

Scoped to CJK Unified Ideographs only — Japanese Hiragana/Katakana and Korean Hangul are not currently segmented. Unlike `GITNEXUS_FTS_STEMMER`, this rewrites stored text — enabling it on an already-indexed repo requires a full `gitnexus analyze --force`; neither `--repair-fts` nor a plain incremental `analyze` applies it to previously-indexed files.

 ### 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.

-### 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).
-

-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).

- * Before #2788 this function re-scanned EVERY parsed file — rebuilding 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

- *   - 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

- *      `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
- *     `twinned` is collected twice and a resolved def flips to `'ambiguous'`

- *   - `both` at the namespace level and in the inline child: pins BOTH
- *     collection sources by nodeId, via the two `both` call sites that select
- *     between them on argument type. Drop own-def collection and the `int`
- *     probe moves; drop inline-child descent and the `double` probe moves. A
- *     pure REORDER of the two stays invisible, and correctly so: the return

-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.                                                                                                                                                        |

-> **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

-
-**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>`)    |

-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).

-
-**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.
-
-| Language   | Shape                              | Before        | After         |
-| ---------- | ---------------------------------- | ------------- | ------------- |
-| TypeScript | `svc?.getUser().save()`            | INVISIBLE-GAP | **RESOLVES**  |
-| TypeScript | `svc!.getUser().save()`            | VISIBLE-GAP   | **RESOLVES**  |
-| TypeScript | `svc.getTyped<User>().save()`      | INVISIBLE-GAP | **RESOLVES**  |
-| C++        | `svc->getUser()->save()`           | INVISIBLE-GAP | **RESOLVES**  |
-| 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.
