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

+## U7 — the go/no-go gate: PASS
+
+A/B produced by reverting ONLY the fold wiring (`compound-receiver.ts` +
+`receiver-bound-calls.ts`) to the pre-U10 commit and rebuilding, so capture
+emission — and therefore the persisted bytes — is identical in both arms and the
+delta isolates the fold. Build + both caches wiped before every run (KTD4).
+
+| Metric | Control | Treatment | Δ | Threshold | Verdict |
+|---|---|---|---|---|---|
+| scope-resolution wall-clock, median of 3 | 25470.0 ms | 25687.9 ms | +0.86% | ≤ +3% | **PASS** |
+| wall-clock, slowest of 3 | 25520.0 ms | 25832.6 ms | +1.22% | ≤ +5% p95 | **PASS** |
+| serialized bytes per emitting site | — | **35.2 B** | — | ≤ 48 B | **PASS** |
+| persisted store growth | 1 234 600 B | 1 235 340 B | **+0.0599%** | ≤ 3% | **PASS** |
+| retained chain payload | — | 740 B | — | ≤ 6 MB | **PASS** |
+| call drops (no regression) | 99 | 99 | 0 | no new drops | **PASS** |
+| peak RSS | — | — | — | ≤ +2% | **NOT RESOLVABLE** |
+
+**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`
+
+| Metric | Value |
+|---|---|
+| **Call drops (the gate number)** | **99** |
+| Total drops, all site kinds | 124 |
+| Split by site kind | `call: 99`, `read: 25` |
+
+Call drops by extension:
+
+| 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).** 25 of the 124 drops — 20% —
+are property *reads*, not lost calls. 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 124 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.
+
+| Language | Shape | State | 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, `$this->repo->save()`, does not need recording — with a typed property
+   it resolves. The genuine PHP gap is the call chain, and it is already visible.
+
+4. **The C++ defect is the `->` base receiver specifically.** `svc->getUser()->save()`
+   is invisible while `svc2.getUser()->save()` resolves. Same chain, same `->save()`
+   tail — only the base differs. This is exactly why `cpp-chain-call/` has never
+   caught it: that fixture uses the value `.` form, which works.
+
+## Known blind spots
+
+Every count here is a lower bound on a known-biased population, and any later delta
+must be read against the same bias.
+
+- Case 0's gate is a C-family punctuation test (`.` or `(`), so a receiver that is a
+  plain property path (`$this->repo`, `a::b`) never reaches the recorder.
+- `repos[0].save()` has neither `.` nor `(` in its receiver — same result.
+- `?.` and explicit type arguments produce no reference site at all.
+
+## 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 chain is minted correctly. The residual is that the fold's base, `$svc`,
+does not bind in the PHP resolver, so the fold returns `undefined` and the site
+falls through to the text cascade. That is PHP binding-key work, not a
+chain-layer defect, and it is left as a recorded residual rather than absorbed
+into this series.
+
+Two incidental corrections from that check, both to KTD6:
+
+- PHP's receiver capture text is normalized to `$svc.getUser()` — DOTS, not
+  `->`. So Case 0's "C-family punctuation" gate fires for PHP after all, which
+  is why the call chain was recorded as a VISIBLE-GAP to begin with.
+- Typing the fixture parameter (`function f(Service $svc)`) moved the row from
+  VISIBLE-GAP to INVISIBLE-GAP: with a type binding the cascade now types the
+  receiver but finds no member, so `compoundReceiverUnresolved` is false and no
+  drop is recorded. An untyped fixture parameter had been reporting a language
+  gap that was really a fixture defect — the same error class as the untyped
+  `$repo` control caught earlier.

+/**
+ * Receiver-resolution measurement harness.
+ *
+ * Answers one question — "how many method calls does GitNexus lose because it
+ * could not establish the receiver's type, and which source shapes are they?" —
+ * and answers it in a way that can gate a decision.
+ *
+ * TWO ARMS, because neither one alone is trustworthy:
+ *
+ *  1. SHAPE ARM (`--shapes`, default). A fixed corpus of receiver spellings,
+ *     each classified by what the graph actually contains:
+ *
+ *       RESOLVES       edge emitted. A test written against this shape starts
+ *                      green and proves nothing. Note this states only that an
+ *                      edge EXISTS — not that it points at the right target. A
+ *                      name-keyed fallback onto a same-named member reads as
+ *                      RESOLVES here, so a shape whose receiver has no
+ *                      well-defined type is not a usable control.
+ *       VISIBLE-GAP    no edge, and a `receiver-unresolved` drop was recorded.
+ *                      Measurable by the count arm below.
+ *       INVISIBLE-GAP  no edge, and NO drop was recorded. The call is lost and
+ *                      the instrument cannot see it.
+ *
+ *     The third state is why this arm exists. Case 0's recorder is reached only
+ *     when the receiver text contains `.` or `(` AND the capture layer produced
+ *     a reference site at all. Measured on this corpus, `svc?.getUser().save()`,
+ *     `svc.getTyped<User>().save()` and `repos[0].save()` are all INVISIBLE —
+ *     so fixing them moves the count arm by exactly zero. Gating solely on a
+ *     drop count would read a working fix as "no improvement".
+ *
+ *  2. COUNT ARM (`--corpus <repoPath>`). Runs the real pipeline over a repo and
+ *     reports drops SPLIT BY SITE KIND. The gate number is `call` only: the
+ *     recorder's gate tests the receiver's punctuation, not the site's kind, so
+ *     property reads (`d.source.kind`) and writes (`x.argtypes = [...]`) land in
+ *     the same bucket as lost method calls and would inflate it.
+ *
+ * KNOWN BLIND SPOTS — reported in every run, deliberately, because the number
+ * is a lower bound on a KNOWN-BIASED population and any delta measured later
+ * must be read against the same bias:
+ *
+ *   - Case 0's gate is a C-family punctuation test, so PHP `$this->repo->save()`
+ *     and `::` receivers never record a drop.
+ *   - `repos[0].save()` has neither `.` nor `(` in its receiver, same result.
+ *   - `?.` and explicit type arguments produce no reference site to begin with.
+ *
+ * MEASUREMENT HYGIENE — a run that skips this is void:
+ *
+ *   npm run build                       # the parse worker runs from dist/
+ *   rm -rf .gitnexus/parse-cache .gitnexus/parsedfile-cache
+ *   node --import tsx bench/receiver-resolution/measure.mjs --corpus <repo>
+ *
+ * `analyze --force` clears NEITHER cache, so a stale shard will happily serve
+ * the previous capture set and produce a confident, wrong number.
+ *
+ * Usage:
+ *   node --import tsx bench/receiver-resolution/measure.mjs
+ *   node --import tsx bench/receiver-resolution/measure.mjs --corpus /path/to/repo

+/**
+ * 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.

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