 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.

 3. **Run impact analysis before editing shared symbols** — `impact` (upstream) for functions/classes/methods others call. Do not ignore HIGH/CRITICAL without maintainer sign-off.
 4. **Run `detect_changes` before commit** — confirm diffs map to expected symbols/processes when the graph is available.
 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.

 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.

-Community detection uses the bundled Graphology Leiden implementation by default. To test the #2337 Icebug migration path without changing default analyze behavior, set:
+> **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.

+### Windows: full-text search unavailable
+
+`analyze` completes, but keyword search is degraded and `doctor` shows the FTS extension failing
+with Windows error 126 (`The specified module could not be found`). The extension needs two
+runtime dependencies Windows does not ship by default:
+
+1. **Microsoft Visual C++ 2015-2022 Redistributable (x64)** —

+2. **OpenSSL 3** — `libssl-3-x64.dll` and `libcrypto-3-x64.dll`, resolvable on `PATH`
+
+The redistributable alone is **not** sufficient. If Git for Windows is installed you already have
+the OpenSSL DLLs — run `gitnexus` from **Git Bash**, or prepend the directory to `PATH` in the
+shell you use:
+
+```powershell
+$env:PATH = "C:\Program Files\Git\mingw64\bin;$env:PATH"
+gitnexus analyze --repair-fts
+```
+
+Without them the index is still built, but without search tables, so `query` returns empty keyword
+results until you re-run `gitnexus analyze --repair-fts` from a shell where the DLLs resolve
+([#2669](https://github.com/abhigyanpatwari/GitNexus/issues/2669)).

 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:
 
 ```bash
 # Increase Node.js heap size

 echo "vendor/" >> .gitnexusignore

+# Exclude a directory across every repo you index, without touching each
+# 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`

+ * Build-free throughput + identity bench for `buildGraphTargetIndex`, the

+ *
+ * #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

+ * imports work; a top-level `await import()` breaks tsx's lexer.
+ *
+ * Without args: prints one JSON object per scale plus the summary.

+/**
+ * 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.

+ *
+ * `realpathSync.native` canonicalizes 8.3 short names and symlinks but does not

+ * 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:

+ * `\\`) before returning, so the prefix can only reach here from caller-supplied
+ * input, which `path.resolve` preserves (#2667).
+ *
+ * Preserving it is load-bearing. The roots this normalizes are not just compared —
+ * they are READ FROM: `resolveBuildRoot` joins `package.json` onto `packageRoot`,
+ * `collectBuildEntries` walks `buildRoot`, and the lockfile lookup walks
+ * `packageRoot`'s ancestors. Node does not re-add `\\?\` for over-MAX_PATH paths,
+ * so stripping here would break analyzer-identity resolution on a deep checkout
+ * exactly as it would at any other filesystem boundary. (These fields are also
+ * compared between an `analyze` and a later `status` run, so a shape change would
+ * additionally risk the #2668 false-stale class — but the filesystem reads are the
+ * reason that matters.)
+ *
+ * Registry-style path COMPARISON is a different domain, never opens what it
