* perf(kotlin): index import resolution instead of scanning per import

`resolveKotlinImportTarget` walked the entire workspace on every import.
Its four tiers — exact/suffix, directory child, package fan-out and
progressive prefix strip — each ran `for (const raw of allFilePaths)` with a
`replace(/\\/g, '/')` and several string scans per entry, and they are tried
in cascade, so one unresolved import cost two to four full passes.

Across a repository with tens of thousands of Kotlin files that is
O(imports x files): on the order of 10^10 string operations on a single
thread. It does not look like a hot loop from the outside - analyze sits at
exactly 1.00 core with a completely flat heap and emits nothing for hours,
because every allocation is a short-lived string and nothing accumulates to
hint at progress. Small repositories hide it entirely: at a few hundred files
each pass is free.

Three maps, built once per `allFilePaths` Set and memoized on its identity,
make each tier O(1): stem -> path for the exact tier, every component-suffix
of the stem for the suffix tier, and directory -> direct children for both the
fan-out and the first-child fallback. Cost becomes O(files) once plus O(1) per
import. This mirrors the existing Python index (`getPythonFileIndex`), down to
the WeakMap keying and the build counter.

Semantics are unchanged, including the parts the scans expressed only through
iteration order:

  - an exact match anywhere beats a suffix match found earlier, because the
    scan returned on the first exact hit but merely remembered the first
    suffix hit;
  - "first match" stays first in set-iteration order, so both stem maps keep
    the earliest path inserted for a key;
  - a directory-name match still honours the scan's `startsWith`-then-`indexOf`
    rule, which only ever considered the FIRST occurrence of `/dir/`. A path
    like `data/src/main/kotlin/com/example/data/Repo.kt` is therefore still
    NOT a child of `data`. That is arguably wrong, but fixing it here would
    silently move edges in every Kotlin repository; it belongs in its own
    change with its own fixtures.

That claim is gated, not asserted. `bench/kotlin-import-target` fingerprints
every `fromFile | targetRaw -> result` triple over an exhaustive branch matrix
plus a deterministic fuzz, each file set resolved in BOTH iteration orders
because that is the only place the tie-breaks above are expressed. The
committed baseline is the value the PRE-INDEX implementation produces: both
implementations print
5ad605c179081505705ff7698a09dbdbdc4831080af6d9fdec5499cc6bce28ee over the same
20074 cases, 11612 of them non-null, and anyone can re-run it by pointing the
harness's module specifier at the old file.

Its second arm is the scaling ratio, `(t_large/t_small)/(1600/400)` over a
synthetic Kotlin monorepo whose imports are ~40% unresolvable — only a miss
drives all four tiers, which is where the scan was worst. The index measures
0.99 (8.0 ms / 31.7 ms); the implementation it replaces measures 3.737
(2207.8 ms / 33003.5 ms) on that same corpus, so the budget of 1.6 separates
them by a wide margin. Take the absolute times as an order of magnitude only
(~276x, ~1041x): the floor arm was run once cold because best-of-seven against
a quadratic implementation costs minutes, while the index arm is the usual
best-of-seven. The ratios are the comparable pair. Both arms run in the
existing always-on `benchmarks (GITNEXUS_BENCH)` job, next to the C++ guard
from #2788 and the Python one from #1918.

Two unit-level guards sit alongside it: a parity test pinning the curated
cases, and an integration test asserting the index is built once across many
imports — the adapter must pass the Set through, since a defensive copy would
hand a fresh WeakMap key per call and restore the old behaviour (the same trap
Python hit in PR #1918).

Two other providers have the same defect and are left alone here, having no
repository at hand to verify a change against:

  - `go/import-target.ts`: `findRootPackageFiles` and `findAllFilesInPkgDir`
    scan unmemoized, and the GOPATH fallback calls the latter once per path
    segment but the last, so a single import can trigger several full passes;
  - `dart/import-target.ts`: the `package:` branch scans once per candidate
    path — `lib/<rel>` and bare `<rel>` — and `resolveRelative` scans again in
    its suffix fallback, also unmemoized.

`csharp/import-target.ts` is a partial case worth noting: it already builds a
memoized `getWorkspaceFileIndex`, but that is reached only when a `.csproj` is
found; the no-csproj path hands the raw Set to `resolveDirectMatch` and
`resolveByProgressiveStripping`, which scan past it.

* test(kotlin): close the blind axes in the import-resolution gate

Review of #2872 found the weak part was the gate, not the resolver: four
plausible follow-up mutations passed `--check` with a byte-identical
fingerprint, `cases` AND `non_null`. Each is now caught, and each was
re-checked against the mutation it exists to stop.

  - The hashed record carried `order | fromFile | targetRaw | result` but not
    the FILE SET, so a corpus edit that swapped the workspace under a case
    while leaving its result string alone was invisible. Leaving the resolver
    untouched and editing only the corpus, two documented load-bearing cases
    could be gutted — the "exact beats an earlier suffix" case losing its
    competing file, the repeated-directory negative case losing its file
    entirely — with the gate green. The file set is now part of the record, and
    that same edit now moves the fingerprint.
  - The corpus capped path depth at 8 components and packages at 16 files,
    which are precisely the two axes the loops this change added run on. It now
    carries 11- and 13-component paths, queries against suffix keys deeper than
    seven segments, a 40-file package, and a fuzz that spans both. Verified:
    capping suffix-key depth at 7, skipping the `dirChildren` suffix loop above
    depth 8, and capping a bucket at 17 entries each now move the fingerprint,
    where all three previously passed.
  - `non_null` was reported but never asserted; it is asserted beside `cases`.
    That closes only the "resolves nothing at all" hole — it stayed 11612 under
    all three code mutations above and under the corpus edit — so it is a
    companion to the two fixes above, not a substitute for either.
  - A ratio cannot see a constant factor, and a file-count ratio cannot see a
    depth cost. `--check` now also asserts a DEPTH ratio (file count fixed,
    paths 24 components against 8) and an absolute ceiling on the small arm: a
    full workspace scan reintroduced on 1-in-32 imports scores 1.490, inside
    the scaling budget, while running 2.8x slower.

The baseline is re-derived, not adjusted: the pre-index implementation and the
index both print
ebf1790bf1d42dad483a51f2cbdeb2351e493b9e8236e4eedeef592dd81e2c5c over the new
20106-case corpus, 13256 of them non-null.

Both test suites were shown to be non-load-bearing and now are:

  - the parity test's repeated-directory case put `data` at the LEADING
    segment, so the `startsWith` guard fired and the `indexOf` rule its own
    comment describes was never reached — a resolver with that check relaxed to
    `>= 0` passed all 18 cases. A mid-path case now pins it, and a backslash
    fan-out case pins `norm.lastIndexOf` against `raw.lastIndexOf`, which was
    also bench-only. Both mutations now fail the unit suite.
  - the index-reuse test discarded all 200 return values, so a build count of 1
    was equally true of an adapter that had stopped resolving anything. It now
    asserts results, and its docstring premise is corrected: every one of its
    imports hit the tier-1 suffix lookup and none reached the fan-out it
    claimed to exercise. Half now genuinely do. The `undefined as never` casts
    and the `?.` are gone — both trailing parameters are optional and the
    member is required.

Resolver changes, all output-identical against the differential above:

  - `dirChildren` buckets are frozen once built. `findKotlinPackageFiles` hands
    a bucket straight out of the index, and the `readonly string[]` return type
    does not survive the caller: the finalize pass normalizes with
    `Array.isArray(t) ? t : [t]`, and `isArray`'s `arg is any[]` predicate
    widens the true branch, so `tsc --strict` accepts a `.sort()` there. A
    downstream sort would permanently reorder the cached bucket and flip the
    first-child tier for every later import in the run.
  - `stripped` is computed only after tier 1 misses, with `lastIndexOf`/`slice`
    instead of `split`/`slice`/`join`. Measured -20% small arm, -21% large arm.
  - `KOTLIN_EXTENSIONS` now comes from the existing `import-resolvers/jvm.ts`
    export instead of a fourth inlined copy.
  - A note on why the shared `buildSuffixIndex` is not reused, with the four
    probes that diverge, and the measured basename-bucket comparison — the one
    place this was less documented than the Python precedent it follows, and
    the question the Go/Dart/C# follow-ups will each face.

feat: close reported graph blind spots in reference resolution, analyze and storage (#2856)
* fix(mcp): report UNKNOWN risk when an upstream impact walk finds no callers

`risk: LOW` asserts "safe to change" — a claim ABOUT callers. An upstream
walk that resolved none has nothing to base it on: the symbol may be
genuinely unused, or reached only through a reference class the index does
not record (a property access on a plain object, a bare-identifier read of a
module-scope const). Seeding LOW from an empty result is the false-safe
signal `anyKnownRisk` already refuses to emit on the ambiguous-candidate
path, and that #2687 removed by making an undetermined impactedCount `null`
rather than `0`.

Zero-caller upstream results now report risk UNKNOWN with a riskNote saying
absence of edges is not evidence of disuse. Downstream is untouched: an
empty downstream walk reports resolved callees, not safety.

* feat(javascript): emit ACCESSES for bare-identifier reads of module-scope consts

A constant read only as a bare identifier — `Math.max(LIMIT, n)`, a default
parameter value, `return LIMIT` — minted no reference site at all, because
JS captured only `@reference.read.member`, which requires a receiver a bare
identifier does not have. So "who uses this constant?", the question behind
every dead-code trim and constants refactor, answered with a confident zero
in both directions.

The rest of the machinery was already in place: `FIELD_KINDS` accepts
`Const`, the scope query already declares it via `@declaration.const`, and
`read` maps to ACCESSES for any resolved target. This adds the missing
capture in VALUE POSITIONS ONLY (call arguments, default-parameter values,
return statements) — a blanket `(identifier)` rule would mint a site for
every token in the file, which is unaffordable at repo scale and would keep
alive the block-local symbols `pruneLocalSymbols` exists to drop.

Cross-file readers are NOT yet covered: the site exists and a call through
the same import statement resolves, but a value-kind def does not link
across the import edge. Recorded as a todo with the investigation.

PARSE_CACHE_VERSION bumped 44 -> 45: this is parse-time capture emission, so
a warm cache replays the pre-change capture set and the new edges never
appear — observed directly, a full `analyze --force` produced a
byte-identical graph until the cache was cleared by hand.

* test(javascript): pin A1/A5 plain-object property acceptance criteria

Fixture plus todo specs for the four shapes plain-object property access has
to answer: object-literal keys indexed as Property nodes, a read through the
holding variable, a property WRITE, and a read through an untyped param.

Records the investigation so the work is resumable: the parse-query pattern
scoped to literals bound to a variable matches correctly (verified against
the raw JAVASCRIPT_QUERIES), but no Property node reaches the graph and
local-symbol-pruner is not the cause — it drops only Const/Variable/Static.
The remaining gate is in the parse worker's node-creation path.

No production code — specs only, so the suite stays green.

* feat(javascript): index object-literal keys of a named object as Property nodes

Idiomatic JS models configuration as an object literal, not a class, but
Property definition nodes existed only for DECLARED CLASS FIELDS. A config
field therefore had no symbol at all: `context({name: 'exitMinAtrMult'})`
answered "not found" for a field read and written throughout a live code
path, and ACCESSES had no target to point at.

Both halves are added for keys of a literal BOUND TO A VARIABLE — the parse
query mints the graph node, the scope query mints the def the resolver can
aim at. Unbound literals are deliberately excluded: an inline call argument
or a JSX prop bag is call-site data, not a named surface other code
references, so a node per key there would add volume without adding an
answerable question.

This lands the definition-node half only. The ACCESSES edges still require
receiver resolution — typing the const that holds the literal to the
literal's scope for the precise case, and name-based matching at reduced
confidence for the untyped-param (option bag) case. Both are recorded as
todos with the mechanism each needs.

Also records a trap that cost a wrong conclusion: under vitest the parse
worker runs the BUILT dist code (parse-impl resolves parse-worker.js, absent
under src/, and falls back to dist), so parse-query changes are invisible to
tests until `npm run build`.

* test(cache): move the SCHEMA_BUMP pin to 45

The pin is the guard that makes two branches claiming one cache-schema
number fail loudly instead of silently serving each other's entries, so a
bump is only half-done until the pin moves with it. The bump itself landed
with the JavaScript bare-identifier captures; this is the other half.

Caught by the guard working exactly as designed — the suite failed with
"expected 45 to be 44" rather than letting a mismatched pair through.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* feat(scope-resolution): resolve plain-object property access by unique name

Idiomatic JS reads configuration off an object whose receiver cannot be
typed — an options bag passed as a parameter, a destructured handle, an
imported literal. No precise pass resolves those, so a field read and
written across a live code path produced no ACCESSES edge at all and "who
reads this setting?" answered a confident zero.

A last-resort pass runs after every precise pass and sees only what they
left behind. For each still-unresolved read/write site it asks whether
exactly ONE Property in the workspace carries that name. If so the read
almost certainly means it. If two or more do, nothing is emitted and the
site is COUNTED as ambiguous — a guess between them would be a coin flip,
and a wrong edge in the pre-edit safety gate is worse than a missing one.

Uniqueness is the right gate because it recovers exactly the names worth
recovering: distinctive domain fields (exitMinAtrMult, bookNotionalUsdt)
are unique in a repo and resolve, while generic keys (id, name, data) are
not and are skipped — which is where name matching would over-connect.

Bounded four ways:
- Confidence 0.5, the global tier, with the inference named in the reason,
  so a consumer can filter inferences without losing scope-resolved edges.
- Never second-guesses a precise result: sites already resolved are
  excluded, because first-write-wins stops a duplicate but NOT a second
  edge to a different target.
- Honors `fieldFallbackOnMethodLookup`. A statically-typed language opts
  out of name matching precisely because it over-connects; inferring an
  ACCESSES edge by name is the same claim and must obey the same opt-out.
- Requires an explicit receiver — a bare identifier is not a property
  access, and matching one by name would link a local to an unrelated key.

Indexes graph nodes rather than scope defs because an object-literal key
mints a Property NODE but no scope-resolution DEF: `localDefs` and
`scope.bindings` are both empty for exactly the population this serves.

* feat(analyze): record a collapsed graph write instead of reporting fresh

The dangerous half of a broken refresh: metadata IS written, so the index
reads as fresh, hooks re-arm, and every tool answers from a graph missing
most of its edges — indistinguishable from a codebase that genuinely has no
such relationships. Reported in the field as edges collapsing 23009 -> 2170
and as a CodeRelation table that never materialized.

`analyze` now compares the relationship count the pipeline PRODUCED against
what the DB hands back after the write. Both numbers are already in scope at
the same point, so the shortfall is provable rather than inferred — no
comparison against the previous index, which cannot distinguish a failed
write from a repo that legitimately shrank. A missing relation table needs
no special case: it reads back as a persisted count of zero.

On a collapse the run records `graphWriteCollapsed` in metadata, which
`getIndexIncompleteReasons` turns into `graph-write-collapsed` so status and
the MCP resources report the index INCOMPLETE rather than fresh.

A ratio, not equality: some relationship types do not round-trip one-for-one
and `--pdg` writes MORE rows into the same table, so demanding equality
would fire on healthy runs. Only a collapse is a defect. Fail-safe when the
expected count is unavailable — an implementation that offloads
relationships out of memory may not be able to report a total, and a false
"your index is broken" is worse than a missed one.

* fix(ingestion): qualify object-literal Property ids by their owning object

Two config objects in one file that share a key name generated the same
`Property:<file>:<key>` id and COLLAPSED INTO ONE node, so two distinct
settings became a single symbol. Worse, the merged name then looked
workspace-unique to name inference, which happily resolved reads of it to a
node representing both — a wrong edge in the pre-edit safety gate, which is
precisely what the unique-name pass is bounded to avoid.

`objectLiteralOwnerInfo` already existed for exactly this ("so two
constructors in one file that both define `bar` stay distinct nodes") but
was gated to `Method`. `Property` now opts in.

`findObjectLiteralBindingInfo` returns `ownerName` only when asked. Its
`Method` ids must stay byte-identical — qualifying them would rewrite every
object-literal method id in every indexed repo — while object-literal KEYS,
indexed only since A1/A5, have no such history to preserve.

Found by a test written for the ambiguity path rather than by review: the
suite reported one node where two were expected, and an edge where none
should exist. Both are now pinned, along with the detection boundaries of
the B2 collapse check, which was previously an untestable inline expression
and is now a pure function.

* feat(typescript): index type aliases and shape members as symbols

A TS frontend models its API contracts as `type X = { … }` and `interface`,
so a field on one is exactly what "who breaks if I remove this?" is asked
about. Three gaps made that unanswerable, all in the TypeScript queries:

1. No `type_alias_declaration` -> `@definition.type`, so an alias minted NO
   NODE AT ALL and a context() lookup on an exported contract type answered
   "Symbol not found". TypeScript was the ONLY language missing this — Rust
   (type_item), Kotlin (type_alias), Swift (typealias_declaration) and Dart
   all emit it. The alias was declared for scope resolution but never became
   a graph symbol.
2. No `property_signature` in the parse query, so INTERFACE members minted no
   Property nodes either — the upstream report's "class/interface index fine"
   holds only for the type, not its fields.
3. No `property_signature` in the scope query, so even with nodes present the
   resolver had no member declaration to aim at. Its sibling
   `method_signature` -> `@declaration.method` already existed; only
   properties were missing.

Interface bodies and object-type aliases both spell members as
property_signature, so one pattern per query covers both shapes.

Lands the SYMBOLS, not yet the ACCESSES edges: the shape is already a
class-like scope and now has member declarations, but no edge forms — the
remaining link is owner/type-binding, recorded as todos with the diagnosis.
Note TypeScript sets fieldFallbackOnMethodLookup:false, so unlike JavaScript
there is deliberately no name-based fallback here; the precise path is the
only route by design.

* test(golden): accept interface members in the mini-repo snapshot

Drift is entirely the new TypeScript shape-member indexing: the fixture's
three interfaces (ValidationResult 2, DbRecord 3, LogEntry 3) contribute
exactly 8 Property nodes, each with exactly one HAS_PROPERTY owner edge.

Verified before regenerating rather than after: every pre-existing count is
untouched (CALLS 9, IMPORTS 12, DEFINES 16, HAS_METHOD 1, MEMBER_OF 12,
STEP_IN_PROCESS 12), so nothing was rewired — the digest moved only because
8 edges were added. The fixture's inline `return { valid: false, … }`
literals correctly produced nothing, confirming the object-literal rule
stays scoped to variable-bound literals.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(analyze): never report a collapse from a non-numeric count

The B2 check reported healthy runs as total graph-write collapses. A
non-numeric `expected` (a graph implementation reporting no total, a
lightweight pipeline result) does not skip the guards — it INVERTS them:
`undefined < 100` is false, so the small-repo exemption never fires, and
`0 >= undefined * 0.5` is `0 >= NaN`, also false, so the ratio check
"passes" as well. Both bounds silently evaporate and every such run is
flagged.

That is precisely the failure this check was written to catch, reproduced
inside the check itself: an unmeasurable quantity treated as a measured
zero. Both sides are now validated as finite numbers before any comparison.

`persisted` is also passed as UNKNOWN rather than zero when the DB was not
demonstrably readable: `getLbugStats` flattens "no connection", "query
threw" and "empty table" all into `edges: 0`, so `stats.nodes > 0` is used
as independent evidence the read happened at all.

Caught by the existing run-analyze suites, not by the new unit tests — those
exercised the pure function with well-formed numbers and were blind to the
integration's actual inputs. Both cases are now pinned.

* feat(typescript): make object-type aliases own their members

A TS object-type alias declares the same `property_signature` members as the
interface beside it and answers the same question, but was not a member
owner: its fields were minted with bare ids and no owner edge, so two
aliases in one file sharing a field name collapsed onto one node, while the
identical interface resolved normally.

`type_alias_declaration` joins CLASS_CONTAINER_TYPES (and
CONTAINER_TYPE_TO_LABEL, as that set's invariant requires — a container
missing there gets orphaned member edges or a wrong owner label). Aliases
with no object type (`type Id = string`) declare no members, so they own
nothing and are unaffected.

This also lands the INTERFACE field -> consumer edges, verified on the
mini-repo fixture rather than only on a purpose-built one: `saveToDb` now
links to `ValidationResult.value`, and `formatLogEntry` to `LogEntry.level`
and `LogEntry.message` — three real contract-field reads that previously had
no graph path at all. Golden updated: +3 ACCESSES, no node changes.

The ALIAS field -> consumer edge is still not linked and is recorded as a
todo with the exact blocker: resolving a receiver typed as the alias needs
the NAME to resolve to a class-like def, and `isClassLike` is
Class|Interface|Struct|Record|Enum|Trait. That predicate is read from ~12
sites including MRO and heritage, and every language mints TypeAlias, so
widening it would enrol aliases in linearizations where they do not belong.
Widening only the scope index was tried and reverted — the type-name walkers
gate on it independently, so it fixed nothing and left dead code. That needs
a deliberate "shape-like" concept, not more call-site widening.

* docs(test): record the traced diagnosis for the unlinked alias field edge

Traced to the end rather than left as "needs investigation", so the next
attempt starts from facts:

  1. Graph side is COMPLETE and symmetric with the interface —
     Property:...:LiveModeConfig.bookSlots is owner-qualified and carries
     HAS_PROPERTY.
  2. Resolution DOES reach resolveClassBindingForName('LiveModeConfig')
     (instrumented) and misses.
  3. It misses because the module scope binds LiveModeIface:Interface,
     renderAlias, renderIface — and not LiveModeConfig. The alias has no
     binding on the receiver's scope chain at all.
  4. The TS scope query tags aliases @declaration.type, but normalizeNodeLabel
     accepts only typealias / type_alias and has no "type" case, so it returns
     undefined. Kotlin and Dart use @declaration.type_alias; TypeScript is
     alone on the dead tag.
  5. Retagging is NECESSARY BUT NOT SUFFICIENT — tried, and the binding still
     does not appear, so a second gate exists in how a declaration anchored on
     a node that is ALSO a @scope.class anchor is attached: the alias appears
     to bind inside its own scope rather than hoisting to Module, where
     interface_declaration evidently does hoist.

An isShapeLike predicate (the nominal-vs-structural split: shapes declare
members, nominal types participate in MRO) plus a mirrored
findShapeBindingInScope were built and REVERTED along with the retag. With no
binding on the chain they never fire, and shipping inert widening is worse
than shipping none — the same standard applied to the earlier scope-index
attempt. The design is recorded here; it is worth doing once step 5 is fixed,
and it also unblocks Rust's parked union_item, which the MEMBER_OWNER_NODE_TYPES
comment documents as the same gap in another language.

* feat(scope-resolution): resolve cross-file value references, skip block-locals

Two halves of the same question, "who uses this constant?".

CROSS-FILE. `resolveReferenceSites` runs against the registries and, as its
own comment says, "imports live in finalized bindings the registries can't
see" — which is why free CALLS need `emitFreeCallFallback`. Reads had no
counterpart, so `import { LIMIT }` followed by a bare use resolved to nothing
while a CALL through the very same import statement resolved fine. This adds
the read/write counterpart, reusing `findValueBindingInScope` (which walks the
FINALIZED chain) rather than inventing a lookup. Confidence 0.9: the import
names the def, so this is precise resolution, not inference.

BLOCK-LOCALS. Bare-identifier capture also matches a read of a block-local
`const`, and an edge to one keeps alive exactly the inert locals
`pruneLocalSymbols` exists to drop — a pruned node becomes a retained node
plus an edge, in every function of every indexed repo. Emission now takes the
set of value defs bound at MODULE scope and drops ACCESSES to
Const/Variable/Static outside it. The cross-file pass carries the same
guarantee structurally: a def in another file cannot be a block-local of this
one, so it skips same-file hits entirely.

The block-local leak was already shipped in the intra-file A2 commit and was
found only because a test was written for the guard rather than the feature —
the same way the object-literal id collision surfaced.

Verified on the full resolver matrix: 3172 tests, golden unchanged.

* fix(lbug): diagnose a vanished staging CSV instead of surfacing a Binder error

A forced rebuild could fail with "COPY failed for File: Binder exception: No
file found that matches the pattern .gitnexus/csv/file.csv" and then an ENOENT
on .gitnexus/csv/rel_Folder_File.csv — two engine-level messages that name
neither a cause nor a remedy, which is where several field reports end.

Only tables with rows > 0 enter the COPY manifest (csv-generator.ts), so an
absent file was WRITTEN during this run and removed since. Both COPY loops now
preflight and say exactly that, with the row count, both causes the reports
point at (a second `gitnexus analyze` on the same repo — they share
.gitnexus/csv — or an external cleanup of .gitnexus/), and the action to take.

Scope note, deliberately narrow: this does not attempt to fix WAL corruption
or checkpoint rotation. Those already have detection and recovery hints
(isWalCorruptionError, WAL_RECOVERY_SUGGESTION, the configurable
wal-checkpoint-threshold), and the ~6000 lines added to lbug/ + storage/ since
v1.6.9 — index-lock.ts most of all, which serializes writers and plausibly
closes the concurrent-run class outright — postdate every report in the
window. Guessing at unreproducible durability faults would be speculation;
making the one failure with NO handling legible is not.

An existing overlap test induced this exact scenario (a manifest entry
pointing at a missing csv) and asserted on the engine's wording. Its intent —
that a node-COPY failure is rethrown at the FK barrier rather than swallowed —
is unchanged and still asserted; only the message it matches moved.

* feat(scope-resolution): split shape-like from class-like, linking alias fields

Completes A4: a field on a TypeScript object-type alias now links to the code
that reads it, the last unanswerable half of "who breaks if I remove this?"
for a TS frontend that models contracts as `type X = { … }`.

`isClassLike` answered two questions that only coincide for classes:
  1. does this declare MEMBERS I can look up?   — a SHAPE (structural)
  2. does this participate in inheritance / MRO? — a NOMINAL TYPE
An object-type alias is (1) and emphatically not (2) — it has no supertypes
and no place in a linearization. Widening `isClassLike` to buy (1) would have
enrolled every language's aliases (Rust type_item, Kotlin/Swift/Dart
typealias, C typedef) into MRO and heritage, so the two questions now get two
predicates. Call sites split by which they ask, and their names already said
which: `resolveInheritanceBaseInScope` and `resolveQualifiedInheritanceBase`
keep `isClassLike`; receiver typing and member OWNERSHIP take `isShapeLike`.

Three parts, each necessary and none sufficient alone:
- `findShapeBindingInScope`, mirroring `findValueBindingInScope`'s established
  relationship to `findClassBindingInScope` (same walker, different accepted
  def-type), consulted only AFTER the class lookup misses so a class of the
  same name always wins.
- `populateClassOwnedMembers` uses it, so alias members get an `ownerId` and
  are registered under the alias. Without this the receiver resolved to the
  alias and then found no members under it.
- The TS scope query tags aliases `@declaration.type_alias`, not
  `@declaration.type`: `normalizeNodeLabel` accepts typealias / type_alias and
  has no "type" case, so the old tag mapped to NO label and TypeScript aliases
  produced no scope-resolution def at all. Kotlin and Dart already spelled it
  this way; TypeScript alone was on the dead tag.

An earlier attempt concluded a further "scope-attachment gate" existed. That
was wrong and is worth recording: scope extraction runs in the parse WORKER,
which loads built `dist`, so the retag was never executed. Rebuilt, the alias
hoists to Module scope exactly as the interface does. Same trap as the parse
query — `src` edits to anything the worker runs are invisible until
`npm run build`.

Typedef and Union stay out of `isShapeLike` deliberately: they belong
conceptually (the union_item note on MEMBER_OWNER_NODE_TYPES records the same
gap) but neither is wired as a member container, so including them would widen
a predicate nothing exercises.

Verified on the full resolver matrix: 3173 tests, golden unchanged.

* test(typescript): pin the type-alias capture to a tag that maps to a label

The capture test asserted `@declaration.type`, the tag that
`normalizeNodeLabel` does not recognize (it accepts typealias / type_alias and
has no "type" case). So the test passed for as long as the tag was broken: it
checked only that the capture FIRED, never that it resolved to anything, while
TypeScript aliases produced no scope-resolution def at all.

Updated to the working tag and given a second assertion that the derived kind
string is one the label mapper accepts — the property that actually matters,
and the one whose absence let a dead tag sit pinned.

* fix(lbug): declare TypeAlias member pairs so analyze does not abort

Making object-type aliases member owners emits HAS_PROPERTY from a `TypeAlias`,
and the relation schema declared no such pair. The emit therefore threw
`UndeclaredRelationPairError` and the ENTIRE analyze died on any repo
containing `type X = { ... }` — a hard stop, not a dropped edge. Found by
running the analyzer over a real 16k-node TypeScript repo, not by a test.

`Method` is declared alongside `Property`: a member written
`type Handler = { onClick(): void }` is a method_signature and would fail in
exactly the same way.

Why every existing test missed it: the resolver suites build an in-memory
graph via `runPipelineFromRepo` and never write to LadybugDB, so the schema
constraint was never exercised. `structural-pair-coverage.test.ts` is the one
suite that does run the emitters against the declared pairs — and its own
docstring names the gap: coverage is bounded by NON_BRIDGE_CORPUS, "a new
structural emitter should land with an entry here". This adds that entry,
pinning TypeAlias|Property and Interface|Property as sentinels.

Verified the guard is not vacuous: removing the pair again makes the suite
fail with undeclaredPairs: ["TypeAlias|Property"].

* fix(processes): trace depth-first so multi-hop flows are detected

D1 ("query ranks frontend components above the backend module that owns the
concept") and D2 ("processes is dominated by trivial mechanical chains") are
the same defect, and neither is about ranking or selection.

The walk stops after a fixed NUMBER of traces, so traversal order decides which
traces those are. Breadth-first reaches every shallow terminal before any deep
one, so the quota filled with the shortest paths in the graph and the walk
stopped — `maxTraceDepth: 10` was never approached. Measured on a real repo
before the fix: of 300 processes NONE exceeded 7 steps and 90% were 3-4. A
multi-hop business flow (signal → order → exit) therefore had no process that
could represent it, and `query` could only rank the mechanical pairs that did
exist. Step 4 of the caller already sorts by length and dedupes by endpoint —
it was always asking for the deepest traces this walk could give it.

Depth-first descends to a terminal first, so the same quota is spent on paths
worth keeping. Cost is unchanged: same budget, same cycle guard, same depth
ceiling — only the order differs.

Measured on the same 16k-node repo, same build and flags, BFS vs DFS (an
earlier comparison was discarded as confounded — it crossed builds and --pdg):

  steps   6-8:  50 → 168   (3.4x)
  totals:      844 → 806

and the reported query moved from `LiveSetupView → Cn` (a React component) to
`ReconcilePositions → IsTpInProfit / WithHeld / ShouldNotify` — server-side
exit management, which is what was asked for.

`traceFromEntryPoint` is exported for the test. Traversal order is unobservable
through `processProcesses`: `findEntryPoints` supplies several starting points,
so a deep chain is traced from inside it whatever the order does. A test at
that level passes under BOTH traversals — the first version of this test did
exactly that and guarded nothing. Driving the walk directly, it fails under
breadth-first with "expected 3 to be greater than 3".

* docs(test): correct a stale status note left behind by a later fix

The A1/A5 header still said "edge resolution REMAINING ... neither is
implemented". Both shapes resolve — the typeable receiver precisely, the
untyped one by workspace-unique name — and the tests below assert exactly that,
so the note contradicted the file it sat on.

It was accurate when written and went stale when the work continued past it.
Left as-is it would tell a reviewer that a landed feature is missing.

The TRAP note is kept: the parse worker still runs built dist under vitest, and
that is still the trap it describes.

* feat(scope-resolution): index literals behind identity-preserving wrappers

`export const INERT_EXIT_CONTRACT = Object.freeze({ ... })` minted no
`Property` node for any of its keys. The object-literal rule matches
`variable_declarator > value: (object)` as a DIRECT child, and freezing puts a
call expression in between — so the shape whose fields are most worth querying
was the one shape the rule could not see. Freezing a config object is how JS
publishes an immutable contract, which is why this reads as a confident zero
on exactly the fields a reader cares about.

The allowlist is three functions, not "any call". `Object.freeze`, `seal` and
`preventExtensions` RETURN THE ARGUMENT THEY WERE GIVEN, which is what makes
the literal's keys members of the bound name. For `const x = compute({ a: 1 })`
the literal is an argument and `x` holds compute's return value, so attributing
`a` to `x` would be a fabrication.

Two negative controls, because the obvious one is vacuous: a bare-identifier
callee is rejected structurally and would pass with no allowlist at all, so the
assertion that actually pins the predicate uses `Object.entries` — identical
shape, differing only by name. Verified load-bearing by adding `entries` to the
allowlist and watching that test alone fail.

SCHEMA_BUMP 46 -> 47: parse-time emission, so a warm cache replays the pre-fix
capture set. Observed as a false negative first — `analyze --force` returned
the old node set until the on-disk cache was removed by hand.

* fix(scope-resolution): narrow multi-candidate property names by scope

Workspace uniqueness was the wrong denominator. Measured on the reporting
repo: `exitMinAtrMult` has 26 `Property` definitions — 16 in one-off
`scripts/`, 7 in the frontend, one in a test, and exactly ONE in the backend
that reads it. Every backend read was refused because of competitors the
reader cannot see. The gate was not too permissive or too strict, it was
scope-blind.

A name with several definitions is now narrowed before being abandoned:
same-file first, then files the reading file directly imports, using the
finalized import graph rather than a path-shape heuristic. Exactly one
survivor at the first non-empty tier resolves; anything else stays refused.
A tier holding several candidates stops the walk instead of falling through —
local evidence that is itself ambiguous still contradicts reaching further out.

Confidence stays 0.5 at every tier. Narrowing changes which candidate is
chosen, not the kind of claim: it is still a name match, and the round-1
contract is that filtering on confidence drops all name inference at once.
The reason string now names the tier that fired.

Ambiguity reporting goes from a count to the actual names (capped), because a
count says a gap exists while the names say which fields are unanswerable.

Measured on that repo, backend readers of `exitMinAtrMult` go 0 -> 24 and
total readers 9 -> 45, including the two call sites in
`oppositeSignalExitManager.js` the report singled out. Both narrowing tests
were mutation-checked by dropping the import evidence and confirming they, and
only they, fail.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* feat(scope-resolution): capture destructured parameter keys as property reads

`function exit({ exitMinAtrMult = 0 })` reads that property off whatever the
caller passes, exactly as `cfg.exitMinAtrMult` would. It never appears in a
member_expression, so it had no reference site at all — and this is the shape
the function that IMPLEMENTS a behaviour uses, so the most relevant reader was
the one systematically missing from "who reads this setting?".

Uses a distinct `@reference.read.destructured` anchor rather than
`@reference.read.member`. The latter is filtered emit-side to matches with a
member_expression ancestor, because calls and writes share its shape, and a
destructuring pattern has none — reusing the tag would have been silently
dropped by that filter. The `read.` head already maps to a read kind, so no
mapping change is needed.

Scoped to formal_parameters. A destructuring binding elsewhere
(`const { x } = require('m')`) is frequently an import rather than a field
read, and minting a property read there would attribute module bindings to
unrelated same-named keys.

All three cases (default value, bare shorthand, renamed key) mutation-checked
by removing the patterns and confirming those three tests, and only those,
fail. The renamed case also asserts the edge points at the KEY and that the
local alias mints nothing.

* fix(scope-resolution): link type consumers to the type they name

An exported contract type owned its members after round 1 and still answered
`incoming: {}`, so "what breaks if I remove this field?" — the question a
contract type exists to answer — had no edge to walk. Measured on the
reporting repo: all 324 TypeAlias nodes AND every Interface node had DEFINES
as their only incoming edge.

Two independent causes, and the second is why the first was not enough.

TypeScript captured no type references at all — only cpp and csharp did — so
an annotation naming a declared type minted no reference site. Added for
annotations, generic arguments and `as` assertions, anchored to those contexts
rather than a bare `(type_identifier)`, which would also match the name in
`type X = …` and make every declaration a consumer of itself.

That alone fixed interfaces and left aliases still empty. `TypeAlias` was
missing from `LINKABLE_LABELS`, so alias graph nodes were never indexed in
`nodeLookup` and `resolveDefGraphId` could not bridge a def to its node — the
edge was dropped AFTER a successful lookup. `CLASS_KINDS` has always listed
TypeAlias and the ClassRegistry returned the def correctly, which is what made
this read as a resolution failure; instrumenting the lookup showed it
returning the right def all along and moved the search one table over. Exactly
the bug already documented two entries above it for Trait.

Fixes every language that spells an alias this way — TypeScript, Kotlin, Dart
and Rust all emit `@declaration.type_alias`.

* feat(scope-resolution): capture record construction as property writes

The read side answered well after the narrowing work while "who SETS this
field?" still missed the code that stamps the value. A record built inline —
`return { exitContract: { exitMinAtrMult: settings.x } }` — is bound to no
variable, so it minted no definition and its keys referenced nothing.

Modelled as WRITE REFERENCES, deliberately not definitions. The round-1 rule
already mints Property nodes for literals bound to a variable; minting more for
anonymous records would add same-named competitors to the very name-narrowing
that makes these fields resolvable — measured at 26 competing definitions for
one field on the reporting repo, which is what made every backend read
unanswerable in the first place. A construction site is a USE of a field, not
another declaration of it.

Two positions only: nested under a key, and returned. Both are records with a
name attached (the key, or the function). An inline call argument
(`doThing({ id: 1 })`) stays excluded for the same reason round 1 excluded it
from definitions — it is call-site data, not a named surface — and is asserted
as such.

The enclosing literal is the receiver and it is anonymous, so these route
through the same narrowing and the same refusal-to-guess as every other
untyped receiver.

Verified on the reporting repo: `entryPlan.js` went from no rows to
`selectExitEnvelope` as a writer of `exitMinAtrMult`. Both captures
mutation-checked.

* feat(processes): select round-robin by terminal so the list is not one flow repeated

Ranking was `sort by length` alone, so the top of the list was one behaviour
described many ways: eleven of the top fourteen processes on the reporting
repo were four entry points crossed with three terminals of the SAME
date-window utility cluster. Genuine call chains, but a reader learns one
thing from fourteen entries, and the repo's own domain flows sat below them.

Selection now round-robins across TERMINALS, deepest first. Depth still orders
within a terminal and still leads the list; what changes is that no terminal
takes a second slot until every other has had a first.

Keying on the entry point was tried first and made it worse — many files
declare a `main`, so each was a distinct entry that round-robin then awarded
its own slot, and `Main -> AlignWindowEnd` went from one row to eight. The
repetition was never in where a flow starts.

Measured on that repo: distinct terminals in the top 20 went 3 -> 20, and its
domain flows (`ReconcilePositions -> ...`) moved into the top 4%.

Two things this deliberately does not claim. The reported cause — ranking
rewarding fan-in, promoting chains ending in widely-called helpers — measured
FALSE: those terminals have one caller each (`alignWindowStart` 1,
`validateSymbol` 1). A fan-in discount was implemented against that hypothesis,
measured, and reverted for moving nothing. And a business flow still cannot be
a process in its own right: the walk only emits at a leaf, at max depth, or on
a cycle, so a flow whose meaningful endpoint calls onward survives only as
whatever leaf it bottoms out in. Both are recorded in the code so neither
reads as settled.

* test(structural-pairs): pin the type-annotation USES pair

R2-2 emits USES INTO a `TypeAlias`, so the pair is `Function|TypeAlias` — a
different table from the `TypeAlias|Property` entry added in round 1, and one
that entry stays green without. `TypeAlias` is on the eleven-table list this
suite exists for, and an undeclared pair does not degrade: it throws
`UndeclaredRelationPairError` and kills the entire analyze on any repo
containing an annotated type. Every resolver suite still passes, because they
build an in-memory graph and never write to the DB.

That exact failure shipped once in this PR already. Two emitters into the same
label, each with its own way to reach a released build.

* fix(scope-resolution): build the module-level set before the out-of-core seal

Review blocker. Under `GITNEXUS_DISK_SCOPE_INDEX=1` the seal replaces every
ParsedFile with a scope-STRIPPED copy, and the block-local filter's set was
built after it — so it walked `scopes: []` for every file, came out empty, and
the filter read that as "no def is module-level" and dropped EVERY
`Const`/`Variable`/`Static` ACCESSES edge in the repo. All languages, all
files, including the module-scope-const edges this PR exists to add. Nothing
threw and nothing logged, on the path the largest repos take: the exact
confident-empty answer the PR is about.

Built above the seal now, from `parsedFiles`, and passed as `undefined` rather
than an empty set when no scope was inspectable — an empty set is a legitimate
answer ("this repo has no module-level value defs") and must not be
indistinguishable from "could not look". Fails open; the block-local exclusion
is still asserted under the seal, since that is correctness rather than
optimization.

Also widens module level past `kind === 'Module'`. A `Namespace` scope (TS
`namespace`, Rust `mod`, C++/C# `namespace`) holds importable values too, and
treating its consts as function-locals dropped their reads. Included only when
the whole chain to the root is Module/Namespace, so a namespace declared inside
a function body stays local — asserted both ways.

That fixture then failed for a third reason: `@reference.read.identifier`
existed ONLY in the JavaScript query, so A2 did not work for TypeScript at all.
Added there, and both languages widened to `variable_declarator value:` and
`binary_expression` operands — the gaps review named between what A2 claimed
and what it matched.

Nothing covered `GITNEXUS_DISK_SCOPE_INDEX`. The new parity test asserts the
seal changes no edge, and was verified against an emulation of the original
bug: same-file readers vanish and only the cross-file reader survives.

* fix(typescript): anchor property_signature to declared shapes

Review blocker, and it reproduces end to end. `property_signature` occurs in
EVERY object_type in the TS grammar, not only in an interface body or an
alias's object type, so inline parameter types, inline return types and nested
object types all matched — and the enclosing-container walk hung each one off
the nearest class, interface or alias. Measured against the unanchored rule,
all four appeared as members of shapes that do not have them:

  Property:contracts.ts:Svc.inlineParamOnlyKey
  Property:contracts.ts:Repo.inlineQueryOnlyKey
  Property:contracts.ts:NestedConfig.nestedOnlyKey
  Property:contracts.ts:buildInline.inlineReturnOnlyKey@46:33

When the inline member shares a name with a real one — `run(opts: { retries:
number })` inside a class that declares `retries` — `addNode` is
first-write-wins and the two distinct symbols merge onto one node, so every
context()/impact()/rename() answer about that field describes the merge. The
sibling JS object-literal rule in this same PR is anchored for exactly this
reason; this is the TypeScript half of the same fix.

`(A (B))` matches DIRECT children, so nested object types are excluded by the
same anchor rather than by a second rule.

The first version of these tests was VACUOUS and is recorded here because the
reason generalizes: a collision and a correct exclusion both leave exactly one
node behind, so counting ids cannot distinguish them. Every inline member in
the fixture is now uniquely named, which is the only thing that discriminates —
verified by restoring the unanchored rule and watching exactly those four
assertions fail. A fifth test asserts anchoring costs no real member.

* fix(analyze): correct the numbers feeding the graph-write-collapse guard

Review blocker. The predicate itself held under adversarial probing; every
defect was in what it was handed and what happened after it fired.

(a) `expected` was wrong twice. Under `GraphEmitSink` streaming the bulk types
leave the heap at parse time and never enter `relationshipCount`, so the count
understated the real volume by most of it and the ratio passed trivially —
on `force === true` runs, which include crash recovery AND the
`analyze --force` retry this check's own warning tells the operator to run.
Adds the manifest totals, the same correction the buffer-pool hint in this file
already makes for the same reason. Separately, an incremental run persists only
the changed subgraph while both counts are whole-scope: a 10,000-edge index
that lost 200 replacements reads 9,800 and is certified complete. The check is
skipped on that path rather than answered wrongly.

(b) A throwing edge count became a measured zero. `getLbugStats` initialised
its total to 0 and ran the query in a swallowing catch, so WAL/lock contention
during finalize — documented on this exact call — reported a healthy index as a
total collapse. It now returns `number | undefined`, and the caller requires
both a readable node count and a defined edge count.

(c) A total loss was exempted for being small. The min-edges rule tested
`expected` before looking at `persisted` at all, so `expected = 99,
persisted = 0` — every edge gone — stayed fresh and reported success. Total
loss is now decided first. The existing test asserted the defect; it now
asserts a PARTIAL shortfall, which is the case the exemption was written for.

(d) A detected collapse reported success and exited 0. It is different in kind
from the other incomplete reasons: those describe a run that did what it said
and left work for later, this one means most of your edges are gone and every
query answers a confident empty. The CLI now prints INCOMPLETE with the counts
and sets a non-zero exit code, and the flag crosses IPC so the worker cannot
send a clean `complete` either.

Nothing exercised this wiring — only the pure helper. Adds tests for all four,
each written so the pre-fix arithmetic fails it.

* fix(scope-resolution): keep unique-name property inference inside one language

The pass indexed `Property` nodes from the whole shared graph. Per-language
gating decides whether it RUNS for a language; it never restricted which nodes
could be TARGETS. So the only carrier of a name could be in another language
entirely, and a read here resolved to it on name uniqueness alone — no owner,
no file, no call path.

Reproduced: a Java class declaring `private int loyaltyPointsBalance` and a JS
`cfg.loyaltyPointsBalance` on an untyped parameter produced an ACCESSES edge
from the JS function to the Java private field. Confidence does not mitigate
it, because `minConfidence` defaults to 0 — the tier is only a filter for
consumers who ask for one.

Candidates are now restricted to files in the language's own `parsedFiles`,
which is a precise restriction rather than a heuristic and needs no new node
property.

Every other fixture in the suite is single-language, so this could not be
caught anywhere by construction. The new fixture is deliberately polyglot and
asserts both halves: no cross-language edge, and a same-language unique name
still resolves.

Known and not addressed here: the index is still O(total graph nodes) and is
rebuilt once per qualifying language, the per-language whole-graph-scan pattern
`phase.ts` hoisted out for `sharedNodeLookup`. Hoisting it belongs with that
machinery rather than in this fix.

* fix(processes): explore siblings in source order, log the exhausted budget

`slice(0, maxBranching)` selected the FIRST N callees while `pop()` explored
them LAST-first, so the trace budget went to the last-declared branch. For
`main() { init(); loadConfig(); run(); shutdown(); }` the walk spends itself on
`shutdown` and can drop `init` — the earliest steps of a flow, which is the
opposite of what a process describes. Selecting first-N and exploring last-first
was simply inconsistent; pushing in reverse makes the stack pop in source order.

Measured on the reporting repo, this costs depth: 6-8 step processes go 168 ->
146 of 816. Still roughly three times the pre-PR baseline of 50, and the right
trade — a deep branch is no longer reached by accident of being declared last.

The remaining limit is the BUDGET, not the traversal: with a fixed quota a deep
branch declared after enough shallow ones is not reached at all. That is now
asserted in both directions rather than left implicit, and the walk logs when it
stops with branches unexplored — a silently truncating cap reads as "this is
everything", the same confident-empty answer this work is about, and the repo
already sets that precedent for `dispatchFanoutSkipped`.

Removes the second depth test, which was vacuous: the note twelve lines above
it already said a `processProcesses`-level depth assertion passes under BOTH
traversals, and measured it does — breadth-first yields the same deepest
stepCount of 8, so it passed with the production change reverted. Traversal
order is asserted against `traceFromEntryPoint` directly; what is observable at
the pipeline level is which traces survive selection, which the diversity tests
cover.

Also renames `queue` to `stack` and corrects the BFS references in the module
docstring and the function's own JSDoc, which is what an IDE hover shows.

* fix(impact): carry riskNote onto ambiguous candidates and separate UNKNOWN's two meanings

Two problems on the ambiguous fan-out, which builds its own candidate object
rather than returning the single-symbol shape.

The narrowed type had no `riskNote` field and never read one, so a candidate
that resolved and found no callers reported `risk: UNKNOWN` with nothing
attached — losing the entire point of the change on the path where the reader
has the least context, since the name is ambiguous there by definition.

And `UNKNOWN` used to mean exactly one thing on this path: the probe threw. The
zero-caller branch gives it a second meaning, so an all-UNKNOWN fan-out could
no longer be told apart from a broken one. Candidates now carry `probeFailed`,
and the comment asserting the old reading is corrected.

Also aligns `gitnexus-web`, which review flagged as giving a different verdict
for the same symbol. That surface answers in prose rather than an enum, and its
message said the symbol "appears to be unused (not called by anything)" — the
identical false certainty in words. It now carries the same MEANING rather than
the same field. Downstream wording is unchanged: no outgoing dependencies
really is a fact about the symbol itself.

* test: replace assertions that cannot fail

Four from review, each satisfied by the defect it was meant to catch.

`new Set(props).size === 2` over two different literal strings can only ever
be 2, so it could not detect the node merge its title promises — that is a
difference in COUNT, now asserted on the raw array.

The ambiguity test asserted only an empty edge set, which is satisfied equally
by "the gate fired" and "the name was never looked up". It now also requires
the ambiguity counter to have moved.

`Interface|Property` was listed as a structural-pair sentinel beside
`TypeAlias|Property`, but both its labels are in the SCOPE_BRIDGE cross-product
so the pair is generated by construction and the sentinel cannot fail. Dropped
rather than left reading as coverage; `TypeAlias|Property` is the load-bearing
one.

`TypeAlias|Method` was declared in the schema with no fixture emitting it — a
declared pair no emitter exercises is indistinguishable from a missing one
until an analyze aborts on a real repo. Adds a method-shaped alias member, and
the suite requires sentinels to actually appear, so it is not vacuous.

* docs: document the new incomplete reason, the UNKNOWN verdict and the id churn

Review found the code changes landed without the guidance around them, and an
agent following this repo's own rules would have been told the wrong thing.

`graph-write-collapsed` joined `INDEX_INCOMPLETE_REASONS` with no Sign block
and no recovery section, while the precedent it cites
(`embedding-checkpoint-pending`) has both — so `gitnexus status` would surface a
new string naming silent wrong answers with nothing explaining trigger or
remedy. Added to RUNBOOK and GUARDRAILS, including why this reason alone also
fails the exit code.

`AGENTS.md` said MUST warn on HIGH or CRITICAL and never mentioned UNKNOWN, and
the shipped impact skill's risk table had no UNKNOWN row and still implied
few-callers ⇒ LOW. An agent obeying those rules literally sees `risk: UNKNOWN`
and proceeds, which negates the change the verdict exists to make. Both copies
of both skills updated.

`MIGRATION.md` now records that process ids do not survive this release —
positional ids plus depth-first tracing, source-order siblings and round-robin
selection mean `proc_7_handle` is a different flow afterwards. Bounded honestly:
nothing in-repo joins on a raw process id, so it is index churn, not a broken
consumer.

`ARCHITECTURE.md`'s scope-resolution stage list gains the two new stages.
The guide skill's node list gains `Property` and `TypeAlias` — the two node
types this work most prominently creates.

Also, on the pair-CSV preflight review asked to confirm: the hard abort IS
deliberate, because a fallback recovering zero rows is the confident-empty
failure this work targets. But the transient the message itself names — a second
concurrent analyze sharing `.gitnexus/csv` — is a race, so the check now
re-looks three times over ~150ms before declaring the file gone. Long enough to
ride out a rename, far too short to mask a file that is genuinely missing.

* fix: drop redundant TypeAlias pairs and keep bare identifiers off class members

Two regressions the full suite caught after the review fixes, both real.

`schema-pair-coverage` failed with eleven hand-declared pairs that a rule now
generates. Adding `TypeAlias` to `LINKABLE_LABELS` — needed so
`resolveDefGraphId` can bridge an alias def to its node — also makes it a
SCOPE_BRIDGE source and target, so the cross-product produces `File|TypeAlias`,
`TypeAlias|Property` and nine others that round 1 had declared by hand. Removed;
the invariant is that no pair is both generated and hand-declared.

This also changes what the structural-pair sentinel means, and the comment is
corrected rather than left overstating it: `TypeAlias|Property` is no longer
load-bearing because the label is off the generated grid — it is load-bearing
because it now depends on `TypeAlias` being IN `LINKABLE_LABELS`. Remove it and
the pair stops being generated while the hand declaration is gone, which is the
same state that silently breaks alias consumer edges.

`block-scope-shadowing` failed because a bare identifier resolved to a class
`Property`. `class Box { baseUrl = '...'; pick() { const baseUrl = ...; return
baseUrl; } }` linked the block-local read to `Box.baseUrl`, duplicating the
legitimate `this.baseUrl` edge. A bare identifier is not a member access: with
no receiver there is no object whose property it could be, and in JS/TS a field
read needs `this.`. Receiver-less read/write sites no longer accept `Property`
hits; callables stay reachable, so `cb = save` naming a top-level function is
unaffected.

That defect PREDATES this branch's TypeScript captures — JavaScript has emitted
bare-identifier reads since A2 and no class fixture exercised the shadow. The
TS parity added here is what surfaced it.

Golden snapshot regenerated after verifying the drift line by line: exactly
+5 USES from type annotations in the mini-repo, every pre-existing count
unchanged, so nothing was rewired.

* perf(scope-resolution): share the property-name index across language passes

Review follow-up. `indexPropertyNodesByName` scanned every node in the graph
and was rebuilt inside each qualifying language pass, reintroducing exactly the
pattern `phase.ts` hoisted out for `sharedNodeLookup` — whose comment records
why it matters: "the previous per-language rebuild burned that CPU+heap N times
and, on a huge repo, a tiny language's full-graph copy overlapped the next
language's — a real contributor to the scope-resolution memory peak."

Built once in `phase.ts` beside `sharedNodeLookup` and `sharedFnNodeIndex`, and
threaded through the same `prebuilt*` seam, so tests and isolated calls still
build their own.

Sharing is only safe because the per-language restriction MOVED rather than
disappeared: the shared index is whole-graph, and candidates are filtered to
the language's own files at lookup time. That also fixes a subtlety the
per-language build had backwards — the cap now applies to the FILTERED set, so
a name carried by forty properties across a polyglot monorepo but only two in
the language being resolved is still answerable, where a global cap would have
refused it.

The tri-state at the lookup boundary is deliberate and the three outcomes are
not interchangeable: no property of this name in this language (nothing to say,
and NOT an ambiguity), too many to choose between (reportable), or a list to
narrow.

Caught mid-change by the polyglot fixture: an intermediate state shared the
index without moving the filter, and the cross-language edge came straight
back. That test earning its keep twice is the reason it exists.

* feat(scope-resolution): report when a field's only anchor is another language

Round 3, found OUT-OF-SAMPLE — six field names appearing in no prior report, so
nothing here was tuned against them. All six answered 0 backend ACCESSES while
their definitions sat in `apps/research-dashboard/**`: TypeScript only. The
in-sample set scored 5/5 and the out-of-sample set 0/6, and the gap is entirely
this.

Per-language inference (`3c5eadc7`) is right and stays. What was wrong is that
declining is INVISIBLE: an empty result for a field anchored only in TypeScript
is byte-identical to an empty result for a field nobody reads. One says "look
in the other language or grep"; the other says "delete it". That is the same
confident-empty failure this series exists to remove, one surface over — and
this time the missing fact is about the ANALYZER's reach rather than the code.

Declines are now counted and named, with the languages the anchors actually
live in, kept SEPARATE from ambiguity because the remedies differ: ambiguity
wants better receiver typing, this wants an anchor in the reading language.
Collapsing them would tell a reader the wrong thing to do. A non-zero count
warns at analyze time regardless of dev mode.

The facts are published as `PipelineResult.propertyInference`, which they had
to be for any of this to be testable — and that exposed a second defect. The
round-2 ambiguity assertion, which I told the reviewer of #2856 I had
strengthened, read its stat off a `scopeResolution` field that does not exist
on PipelineResult: the `if (undefined) return` guard swallowed it and the test
passed with the production code deleted. Both that assertion and the new ones
now read the published field, and the guard is an assertion rather than an
escape. Verified by deleting the counter and watching them fail.

Reported by the same round-3 method note that caught it: verifying a fix
against the cases it was written for only proves those cases pass.

* feat(context): explain an empty property result caused by a cross-language anchor

The other half of R3-1. The analyze pass now knows which fields it declined to
link because every definition of the name lives in another language; this puts
that fact where it is actually read.

`context()` on such a field previously returned an incoming list byte-identical
to a genuinely unread field. The two demand opposite actions — "look in the
other language, or grep" versus "delete it" — so the difference has to travel
with the answer:

  unresolved: property reads of this name were NOT linked: every definition of
              it is typescript, and name inference does not cross languages.
              An empty or short incoming list here is not evidence the field is
              unused — confirm with a text search, or give it an anchor in the
              reading language.
  anchorLanguages: ['typescript']

Carried through repo meta because the graph cannot answer it: the unlinked
reads mint no edge and no node, so the only record is the pass that declined
them.

Keyed on the NAME, not on the resolved label. Gating on `=== 'Property'` was
tried first and is wrong — the label reads `''` on this path for a plain
Property node, so the gate silently suppressed the entire feature while every
test still passed. Caught by asserting the field is DEFINED rather than
guarding on it, which is the same anti-pattern that made two earlier
assertions vacuous. The meta list only ever contains property names, so
matching the name is itself the type check.

Cached per (index, indexedAt): `ensureInitialized` deliberately avoids a
per-call `loadMeta` because every tool routes through it, so this re-reads
exactly when a re-analyze could have changed the answer and never otherwise.

* feat(scope-resolution): report declined property reads for opt-out languages too

Generalizing R3-1 rather than waiting for it to be re-reported in the other
direction. The reported case was a JavaScript read whose only anchor was
TypeScript; the mirror — a TypeScript read anchored only in JavaScript — was
still silent, because a language that sets `fieldFallbackOnMethodLookup: false`
had the whole pass skipped, and skipping emission also skipped REPORTING.

Detection is not inference. Counting what could not be linked asserts nothing
about what it means, so `reportOnly` runs the pass for its facts while emitting
no edge, and the opt-out keeps protecting exactly what it protected before.

Two things this turned up that a single-instance fix would have missed:

The cross-language fixture could NOT prove `reportOnly` is load-bearing — the
per-language candidate filter already blocks those edges, so the assertion
passed with the flag forced off. The case that discriminates is a SAME-language
TypeScript read that name inference could legitimately link and the opt-out
forbids; forcing the flag off there emits `readsTsOnly -> tsOnlyBudget`, which
is the violation.

Getting to that case surfaced a sibling gap, recorded but NOT fixed here: the
object-literal `Property` rule is JavaScript-only, so `const CONFIG = { ... }`
in a `.ts` file mints no node and its keys are invisible. The first draft of
this fixture used exactly that shape and could not discriminate for that reason.
It is the TypeScript half of R2-1a and wants its own change, not a rider on
this one.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* feat(typescript): index object-literal keys, as JavaScript already did

The sibling recorded in `0c5a4f64` and deliberately left out of it. Both the
named object-literal rule (A1/A5) and the identity-wrapper rule (R2-1a) lived
only in JAVASCRIPT_QUERIES, so the single most common config idiom in
TypeScript —

    export const tsRuntimeConfig = { tsConfigRetries: 3 };

— minted no node for any key. `context()` answered "Symbol not found" and a
precise read through the holding variable had nothing to resolve to.

TypeScript sets `fieldFallbackOnMethodLookup: false`, so these gain no
name-based inference. What they gain is the PRECISE path, which is the route
TypeScript is meant to use: `tsRuntimeConfig.tsConfigRetries` has a typeable
receiver and now resolves. A read through an untyped receiver stays unresolved
and, since `0c5a4f64`, is reported as such rather than answering an empty set.

Scoped exactly as the JavaScript rules are — bound to a variable, and for the
wrapper only the three functions that return the argument they were given —
with the same `Object.entries` negative control pinning the allowlist.

Found by fixture, not by report: the first draft of the `reportOnly` test used
a TS `const CONFIG = { ... }` as its discriminator and could not discriminate,
because the shape mints nothing. That is the whole argument for sweeping a
class instead of waiting for each instance to be filed.

SCHEMA_BUMP 47 -> 48: parse-time, so a warm cache replays ParsedFiles carrying
none of these matches and the keys stay invisible.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* feat(scope-resolution): anchor anonymous returned object literals to their function

The last gap round 3 named, and the dominant shape in idiomatic JS: 437
`return {` sites in a single backend directory of the reporting repo, including
the ~25-field payload of its entire signal pipeline. The literal binds to
nothing, so its keys could not even be named — "who reads wickRatio?" had no
symbol to ask about.

The enclosing FUNCTION is the owner: the literal is that function's return
shape, a contract its callers consume. Keys qualify as `<function>.<key>`, so
two functions returning the same name stay two shapes rather than one merged
symbol, and multiple returns in one function stay distinct by position.

RECONCILING THIS WITH R2-1b, which deliberately modelled returned keys as WRITES
to avoid adding same-named competitors to narrowing. These are definitions, but
narrowing now ranks DECLARED anchors — named literals, class fields, interface
and alias members — strictly above return shapes. A name that already resolved
keeps resolving to what it resolved to before, so the competitor problem R2-1b
was avoiding cannot come back. Mutation-checked: dropping that ranking breaks
five pre-existing R2 resolutions.

That also required an R2-1b assertion to change, and the change is a
strengthening rather than a concession. It asserted `toHaveLength(1)` — no new
definition — as a proxy for "adding definitions must not move an existing
answer". The proxy is now false while the property still holds, so the property
itself is asserted directly.

No `HAS_PROPERTY` edge from the function: that would be a `Function|Property`
relation pair the schema does not declare, and an undeclared pair does not
degrade — it throws and kills the whole analyze. That already shipped once in
this PR.

Two things found by dumping rather than assuming, both fixed here:

SHORTHAND keys were not matched at all. `return { symbol, interval, score }` is
the commonest spelling and the reporting repo's own payload is mostly this form,
but tree-sitter models it as `shorthand_property_identifier`, which `(pair)`
does not match. Caught by dumping the golden fixture and seeing a literal
returning `{ level, message, timestamp: Date.now() }` had indexed only
`timestamp`. Now covered in return position AND in the variable-bound rule,
which had the same gap.

Provenance was flagged by owner-presence, which mislabelled the anonymous case:
a callback's return shape yields no name to qualify by, so it looked like a
DECLARED anchor and would have outranked real declarations. Flagged by position
now — a different question from whether a name could be derived.

SCHEMA_BUMP 48 -> 49. Within one PR the version only has to differ from main's,
but a build stamped 48 was installed and used to analyze before these captures
existed, so caches stamped 48 carry none of them — the intermediate-build hazard
this ledger already records for 33/34.

Golden regenerated after verifying the drift: exactly +10 Property and +10
DEFINES, every pre-existing count unchanged.

* fix(scope-resolution): rank production anchors above test fixtures

Found by testing R3-4 on the reporting repo instead of on its fixtures. Anchoring
returned literals took `wickRatio` from 6 definitions to 13 — and backend reads
still resolved to nothing, because SEVEN of the new JavaScript anchors compete
and four of them are in `tests/`. A test constructs throwaway shapes carrying
production field names; a read in shipped code cannot mean one of them.

Applied before the declared/return-shape split, because "is this the shipped
program" is the stronger signal — a declaration inside a test fixture is still a
test fixture. Skipped when the READER is itself a test, since a read there
legitimately means the test's own shape.

The first version of this test was vacuous and the mutation check caught it: the
reader sat in the same file as the production anchor, so the same-file tier
resolved it whether or not this tier existed. The reader now lives in a file
that imports neither anchor, which leaves production-vs-test as the only thing
that can decide.

Honest about what this does NOT do: it narrows `wickRatio` from seven candidates
to three, and three functions in different files each returning that field is
GENUINELY ambiguous — refusing is correct, and the ambiguity is now counted and
named rather than silent. The reported question ("who reads wickRatio?") is
answerable only where one producer exists; where several do, the honest answer
is the list of producers, which R3-4 made nameable for the first time.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* feat(scope-resolution): resolve members through a call result's return shape

The question three rounds of reports could not answer, and the one narrowing
must refuse by design: a field produced by SEVERAL functions. A read of
`spike.wickRatio` could mean any producer, so name inference correctly declines
and no amount of tier-tuning changes that. It needs evidence, not inference.

The evidence existed in two halves that had never been joined. The call-result
type binding (`const alert = formatSpikeAlert(row)` binds `alert` to a TypeRef
whose rawName is the callee) predates all of this work; it simply had nothing to
resolve to when the callee returned an anonymous literal, because an anonymous
literal named nothing. R3-4 gave it a name. Joining them:

    const alert = formatSpikeAlert(row);
    alert.wickRatio   ->   Property:...:formatSpikeAlert.wickRatio

Precise, at ordinary emission confidence, and it works EXACTLY where narrowing
cannot: several producers sharing a field name stop being competitors because
the receiver says which one. Runs before the name fallback and claims its sites,
so a precise answer is never second-guessed by a name match.

Measured on the reporting repo: 1,410 precise edges, and all six fields round 3
verified OUT-OF-SAMPLE go from 0 backend readers to 7, 11, 10, 7, 6 and 14.
Round 3 scored 0/6 on that set; this is 6/6.

The bound is asserted, not just documented: a read off a BARE PARAMETER has no
binding here, because typing it needs the caller's type to flow in — that is
inter-procedural and genuinely larger. Those reads still fall through to name
inference and are still reported when it declines. The fixture has two producers
sharing a field name precisely so the test cannot pass by name matching, and
mutation-checking the owner lookup fails it.

No SCHEMA_BUMP: this is scope resolution, not parse-time capture, so a warm
cache already carries everything it reads. Noted in the ledger because the
reflex on this branch has been to bump, and an unnecessary bump costs every user
a full re-parse.

* Revert "return-shape anchoring" (R3-4/R3-5): it degrades query

Reverts af5eec5c, c764847a and 4f93f32e. The capability was real and measured —
all six fields round 3 verified OUT-OF-SAMPLE went from 0 backend readers to
7/11/10/7/6/14, 0/6 to 6/6, via 1,410 precise return-shape edges. It is reverted
anyway, because it costs more than it buys in its current form.

`cli-limit-e2e` caught it. Bisected to af5eec5c: on the mini-repo fixture,
`query('message')` returned two processes before and NONE after. The mechanism
is not window displacement — that hypothesis was tested with a partition that
kept function-local property keys from taking window slots, and it changed
nothing. Indexing the keys of every returned literal adds many nodes whose names
are ordinary words, which moves the BM25 CORPUS statistics: "message" gets less
discriminating, and `createLogEntry` — the callable that actually carries the
processes — stops ranking at all. A corpus-level effect is not repairable by a
tie-break.

Trading a regression in `query`, one of the core tools, for coverage in
`context` is the wrong trade, and shipping it because the number was good would
be the same mistake this PR spent three rounds removing: a confident answer that
is worse than the honest one.

What the work established, and what re-landing needs:

  - The mechanism is right. Joining the existing call-result type binding to a
    named return shape resolves `alert.wickRatio` by EVIDENCE, which is why it
    succeeds exactly where name inference must refuse.
  - The cost is search dilution, and it needs to be measured on BM25 ranking
    BEFORE the capture lands — not discovered by a downstream e2e test.
  - The likely shape of the fix is keeping return-shape keys out of the text
    search corpus while keeping them in the graph, which needs persisted
    provenance rather than the in-memory flag used here.

Kept: everything through 8972d223, which is verified green.

* feat(search): give the index a notion of DETAIL symbols, and re-land R3-4/R3-5

Reverts the revert. The return-shape work was correct and measured — 1,410
precise edges, and all six fields round 3 verified out-of-sample going 0/6 to
6/6 — and it was dropped for a regression that was really a MISSING LAYER: the
search index had no way to say "this symbol is queryable but is not a concept a
text search should surface on its own".

Indexing the keys of anonymous returned literals adds many nodes whose names are
ordinary words (`message`, `value`, `timestamp`). Without that notion they
compete on equal terms in FTS, push the CALLABLES named after the same concept
past the search's row cap, and `query('message')` returned two processes before
and none after.

The layer, rather than a workaround:

  - `Property.isDetail`, persisted. A Property-only column, which that table
    already precedents with `declaredType`, set where the key is minted.
  - `buildFtsQueryCypher` filters on it for the Property table, BEFORE the row
    cap. That placement is the whole point: rows crowded out never reach the
    caller, so no downstream re-ranking can recover them. Two downstream fixes
    were tried first — a tie-break and a partition of the merge window — and
    recovered nothing, which is what located the real seam.
  - `IS NULL`-tolerant, so an index written before the column existed still
    answers instead of returning nothing.

Verified by the A/B that found the regression: the query's result order is now
byte-identical to the pre-R3-4 baseline —
`proc_0_processrequest, proc_2_errormiddleware, Function:createLogEntry,
Property:LogEntry.message` — with the return-shape coverage retained.

The determinism guard then caught prose in the new DDL comment containing the
token this repo scans for, which would have read as an unordered query. Reworded;
that suite is doing exactly its job.

* feat(processes): let a flow end where the program reaches outward

The item three rounds kept circling. A trace was only emitted at a node with NO
outgoing calls, so a real flow — scan, score, arm, PLACE THE ORDER — is always a
PREFIX of some longer chain that runs on into date helpers, and could never be a
process in its own right. Ranking could not fix that; the flow was never a
candidate to rank.

What blocked it was signal granularity, and the fix is the layer that was
missing rather than a heuristic. GitNexus already knew where the program reaches
outward: the parse phase collects fetch calls and ORM queries carrying
`filePath` + `lineNumber`. Those facts only ever produced FILE-level edges
(`File -[FETCHES]-> Route`), which cannot end a trace — every function in a file
containing one would qualify. Attributing each site to the function whose range
CONTAINS it turns the same facts into the function-level signal the walk needs:
no new extraction, no new relation pair, no schema change. Innermost wins, so a
closure that performs the call is the sink rather than the function spanning it.

Three touch points, and the second is the one that makes or breaks it:

  - the walk emits at a sink AND CONTINUES, so `placeOrder` is an endpoint while
    `placeOrder -> formatDate` still exists separately;
  - subset-removal PRESERVES sink-terminated traces. A sink flow is by
    definition a prefix of the chain that runs past it, so emitting one at the
    walk and deleting it one step later would have been a no-op. Mutation-
    checked: removing this preservation fails all three sink tests, including
    the one asserting the sink is reached at all;
  - selection ranks sink-terminated above leaf-terminated, then by depth.

`processes` now declares `parse` as a dependency. It historically avoided that
on the grounds the dependency was spurious for a progress counter — it is no
longer spurious, so it is declared rather than reached for implicitly, and the
read fails open so a pipeline without that output detects no sinks instead of
losing every process.

Bounded honestly: this fires where fetch/ORM extraction fires. On the reporting
repo it will do nothing until route detection handles hand-rolled dispatchers,
since that codebase routes with `pathname === '/api/...'` on raw node:http and
produces zero Route nodes — a separate gap, and the next one worth closing.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* docs(processes): the comment above the sink ranking still described it as unreachable

R3-6 taught the walk what a sink is, but the block explaining the ranking still
carried the paragraph written when that was out of reach — "a business flow
still cannot be a process in its own right ... fixing that means teaching the
walk what a sink is" — sitting directly above the code that does exactly that.
A reader arriving at `rankedByInterest` would take the limitation as current.

The measured-false fan-in finding stays; it is still true and still worth not
re-deriving. What replaces the stale half is the bound that IS current: sinks
fire where fetch/ORM extraction fires, so a codebase whose outward calls are not
detected as such still sees leaf-terminated traces only.

* feat(routes): read a route that is declared by a comparison, not by a framework

`route_map` on the reporting repo returned

    {"routes": [], "total": 0, "message": "No routes found in this project."}

for a codebase with SEVENTEEN route modules, an `apiRouteTable.js`, and 113
path comparisons. Not a partial answer — a statement about the code, and a
false one. Same confident-empty class as the rest of this branch, except here
it takes out a whole tool.

Four route-discovery paths existed — filesystem convention, single-file
framework route, cross-file framework route, decorator — and every one of them
needs a FRAMEWORK to declare the route. A raw `node:http` server declares it
the only way the language offers:

    if (req.method === 'GET' && pathname === '/api/live/portfolio') { … }

A path, a verb, and a handler. Nothing in the pipeline could read it.

The failure modes are not symmetric, so the rules are weighted accordingly: a
route this misses is a coverage limit, a route it invents is `route_map`
asserting something false. A comparison therefore qualifies only against a
demonstrable request path (`pathname`, `*.pathname`, `req.url`; `path` is
excluded — in Node it is overwhelmingly `node:path` or a file location), and
anything untranslatable is dropped rather than approximated:

  - `pathname.startsWith('/api/')` is a namespace test; minting `/api` would
    claim a route nobody serves;
  - a bare `pathname === '/'` with no verb is more often the static-file
    normalisation branch (`pathname === '/' ? '/index.html' : pathname`) than a
    route — WITH a verb the intent is unambiguous, so that form IS taken;
  - an anchored regex converts only when its body is a literal path plus
    single-segment wildcards, so `/^\/api\/research-runs\/[^/]+$/` becomes
    `/api/research-runs/{param1}` while an optional group or an alternation
    bails.

Three things went in that nobody reported, each found by measuring rather than
by a second report.

`switch (pathname) { case '/api/x': }` is the same dispatch in different
syntax, and waiting for a bug report per shape is how a graph stays permanently
one idiom behind the code it indexes.

The reconciliation had to move up a level. The reporting repo keeps its path
table (`isKnownApiPath`) in one module and its handlers in sixteen others, so a
per-file rule sees each half separately and lists every route twice — once
verb-less with the table as its "handler", once properly. Measured: 22 of the
first 94 routes were that shadow. Only the whole registry can tell them apart,
so the rule lives in the routes phase and touches dispatch-guard routes only —
a framework route without a verb is method-agnostic BY DECLARATION (a Django
function view, a Laravel resource), a fact rather than a weaker observation.

And a path composed from a constant needed folding. One of those seventeen
modules writes every one of its routes as `` `${autoTradeBasePath}/rules` ``,
where the base is an alias of a module-level literal. Refusing that lost the
whole file — and lost it INVISIBLY, since a module with unfoldable paths and a
module with no routes are the same empty answer. Same-file only, literals only,
one alias hop, and it refuses on ambiguity: a name declared twice with
different values is dropped rather than guessed, because a partially-folded
path is a wrong route and a wrong route is the failure this module exists to
avoid.

Wiring is a LanguageProvider hook, not a language check in shared code.
`extractDecoratorRoutes` was already the general "route from this file's own
AST" channel rather than a decorator-only one — express routes have flowed
through it as `decorator-express.get` for a while — so the transport, the
`(method, url)` dedup and the handler-symbol resolution all apply unchanged.
`ExtractedDecoratorRoute.source` carries the one thing that genuinely differs:
a decorator route is DECLARED, a dispatch-guard route is INFERRED. The walk is
gated behind a substring pre-filter so it costs nothing on files that cannot
produce a route, and the gate is sound by construction — every rule reaches a
route only through `isPathExpression`, which needs one of exactly those tokens.

SCHEMA_BUMP 49 -> 51, two entries. Decorator routes are worker output carried
in the parse cache, so a warm cache replays results predating the extractor and
`route_map` stays empty — the symptom this fixes, wearing the mask of "the
extractor does not work". The second bump is the v34 hazard tripping again: a
build stamped 50 had already been used to analyze before folding existed, so
caches stamped 50 carry the unfolded route set. Caught by measuring — the
post-folding run came back suspiciously fast and would have reported the
pre-folding number.

* fix(scope-resolution): ask whether a value def is FUNCTION-LOCAL, not whether it is module-level

The locality filter for value references was written as an ALLOWLIST of
module-scope defs, and that shape cannot express a class member. A value def has
three homes, not two: module level, a function body, and a CLASS body. Java and
C# fields and Python class attributes live in the third, so an allowlist keyed on
"module level" excludes every one of them by construction.

The guard written to make that safe could not fire either. The set arms whenever
a Module scope is FOUND, and Java has module scopes while having no module-level
values at all — so for Java it armed permanently empty, which is exactly the
state the guard exists to distinguish from "there genuinely are none".

Inverting it removes the class. A blocklist of defs positively identified as
function-local fails safe: a Java field, a Python class attribute, or a language
whose scopes could not be inspected is emitted rather than dropped. That also
retires the arming flag — an empty blocklist and an uninspected one mean the same
thing, and both mean "emit". The failure mode moves from "silently deletes an
edge class" to "retains an inert local", which is the right direction for a tool
whose stated principle is that a confident empty answer is the worst outcome.

MEASURED, because the review that prompted this reported it as a P0 deleting
every Java/C#/Python field ACCESSES edge, and that half does not reproduce.
Instrumenting the bridge over `java-write-access` shows ZERO value-ACCESSES
candidates reaching the filter: Java field references resolve to a `Property`
target and `isValueDefinitionLabel` covers only Const/Static/Variable, so the
filter is never consulted there. Pipeline-level edge sets are byte-identical with
the filter forced on and forced off, across four shapes — Java cross-file field
writes, Java cross-file constant reads, Java bare same-class constant reads, and
a Python module-constant/class-attribute mix. The defect is real and latent; the
blast radius is not. Fixed anyway, because the predicate asks the wrong question
and the next change that makes the bridge the sole emitter would ship the
deletion for real.

New `value-ref-locality.test.ts` pins the invariant triple — local dropped,
module-scope kept, class member kept — by TARGET rather than by `reason`. The
per-language suites filter on `rel.reason === 'read'|'write'` while the bridge
stamps `scope-resolution: read|write`, so they are blind to bridge-side change in
both directions. The file states plainly which half gates the mechanism (JS,
mutation-verified) and which gates only the outcome (Java, because the mechanism
is unreachable there), so it cannot be mistaken for a stronger gate than it is.

* fix(docs): restore the agent guidance a generated-block refresh deleted

Commit 8f8261021's message is entirely about cross-language anchor reporting; it
also regenerated the `gitnexus:start` block in AGENTS.md and CLAUDE.md against a
LOCAL, non-PDG index and swept six documentation/config files along with it. The
review caught this and it is correct. Restored:

  - the index stats, which regressed 248612 symbols / 565510 relationships /
    918 flows -> 29969 / 118986 / 762 — my machine's index described as the
    project's;
  - the whole `pdg_query` bullet and the PDG half of the impact bullet, while
    both capabilities remain live in `mcp/tools.ts` and `local-backend.ts`;
  - the "Inline staleness signal" section in the guide skill, content that never
    left `origin/main` and that this branch had no reason to touch;
  - `.mcp.json`, which had moved from `npx -y gitnexus@latest mcp` to a bare
    `gitnexus` — a fresh clone with no global install gets a dead MCP server.

The worst of it is self-inflicted in a specific way worth naming: commit
411cac9b9, four hours earlier on this same branch, ADDED the instruction telling
agents not to read `risk: UNKNOWN` as an all-clear. The refresh deleted it. So
the branch shipped a new UNKNOWN verdict and simultaneously removed the guidance
for reading it — the exact false-safe this PR exists to remove, reintroduced one
layer up in the docs.

Re-applied that guidance, and found the drift is wider than reported. The review
noted the `.claude/` copy contradicting the plugin mirror; in fact the UNKNOWN
block was present in ONE of five shipped distributions. `gitnexus/skills/` (the
npm package), `gitnexus-cursor-integration/`, and `.agents/` were missing it too,
so every non-Claude consumer of this skill had the old table.

`shipped-skills-sync.test.ts` passed 54/54 through all of that. Its byte-identical
check covers only the plan/work/review/lfg family, and the standard skills are
guarded solely by per-skill fragment lists — so a fragment nobody listed is a
fragment nothing protects. Added the UNKNOWN fragments to that list, plus a
`copies.length > 1` assertion so an empty copy list cannot make the loop vacuous.
Verified it fails against the pre-fix tree.

* fix(scope-resolution): require the return-shape producer to RESOLVE, not merely to name-match

Review finding 2, reached independently by three Claude lanes and two Codex
legs, and reproduced here. `emitReturnShapeMemberAccesses` took the receiver's
type binding, then filtered a WHOLE-GRAPH property index with `idNamesMember` —
a textual match on the node id. Any node whose id happened to read
`<producer>.<member>` qualified, in any file and any language, and it emitted at
the 0.9 PRECISE tier where a `minConfidence` floor cannot filter it out. The
sibling unique-name pass was given a per-language restriction for exactly this
hazard; this pass consumed the same shared index with none.

Three guards, catching different shapes:

  - the producer must RESOLVE to a definition (`findCallableBindingInScope` — a
    CALLABLE lookup: the producer is the function whose return shape owns the
    member, and it resolves through finalized import bindings so a producer in
    another file still yields its own file);
  - the member must live in that definition's file;
  - that file must belong to the language being resolved.

The third is not redundant with the second, which is the part worth recording.
A receiver typed by CONSTRUCTION (`const bound = new Loyalty()`) resolves through
the shared class registry, which is polyglot — so the producer resolves into
`Loyalty.java`, its members legitimately live in that same file, and file
equality waves the cross-language edge straight through.

Also fixes the sibling P2: a site where the receiver IS typed to a producer that
owns no such member now claims the site. That branch is the strongest negative
evidence the pipeline can produce, and letting it fall through meant the 0.5 name
fallback answered a question the precise pass had just DISPROVED — measured,
linking a read to an unrelated same-named key in another file.

`polyglot-property-isolation` gains the bound-receiver arm the review asked for,
and it is the right arm: the pre-existing case has an untyped receiver and so
only ever exercised the unique-name pass, while one extra token routes an
identical read through this one. Mutation-verified — restoring the pre-fix
matching makes exactly the new leak assertion fail. The first version of that arm
was silently vacuous (it introduced a JS key of the same name, which destroyed
the fixture's Java-only premise), which is why it now asserts on the TARGET FILE
rather than on the absence of a name.

KNOWN LIMIT, stated rather than papered over: a member-call producer
(`const r = svc.make()`) binds `svc.make`, which resolves to no callable, so this
pass now declines it. Codex B3 raised that converse case and it is real. Fixing
it means typing `svc` and then finding `make` on that type — a larger piece of
work, queued for the follow-up PR. Declining is the correct interim behaviour:
the alternative is matching `make.<member>` by name across the graph, which is
the fabrication this commit removes.

* fix(scope-resolution): resolve the import map by point lookup so the seal cannot empty it

Review finding 4, reproduced end-to-end by two lanes: the same commit and the
same repo produced a DIFFERENT graph depending on `GITNEXUS_DISK_SCOPE_INDEX`.

`buildDirectImportMap` built `scopeToFile` by walking `parsed.scopes`. The
out-of-core seal replaces `emitParsedFiles` with a scope-STRIPPED copy — that is
its documented contract, scopes are reachable only via `scopeTree.getScope`
afterwards — so under the seal the map came out empty, every `directImports`
lookup returned undefined, and tier-2 narrowing died repo-wide.

The reporting is the worse half. The loss surfaced as `ambiguous`, which means
"several candidates and the pass refused to choose". The truth was "the evidence
was discarded one function earlier". A reader acting on that would go looking for
better receiver typing to fix a problem that was not there.

This is the SECOND consumer of `parsed.scopes` on this branch to hit the seal.
The first was hoisted above it. This one is converted to the point lookup
instead, which is the stronger fix: a point lookup survives the seal by contract,
so there is no ordering left for a future edit to get wrong.

The parity assertion that would have caught it now exists. The sealed harness in
`javascript-const-references` already ran the fixture both ways, but every
assertion in it pinned ONE field's readers — which is exactly how a second
instance slipped in, since no assertion happened to cover a narrowed name. It now
also compares the WHOLE ACCESSES edge set between the two runs, as a sorted diff
so a failure names the edges that moved, with a non-empty guard so two empty sets
cannot compare equal and assert nothing. Mutation-verified: forcing the map empty
fails it.

* fix(scope-resolution): bind a producer's own returned key to itself, and stop claiming uniqueness for a ranked answer

Review finding 3, accepting the two defects it demonstrates and declining the
remedy it proposes. Both halves are mutation-verified.

1. A SITE INSIDE ITS OWN RETURN SHAPE NOW BINDS TO ITS OWN KEY.

   `export function buildB(row) { return { tickIntervalMs: row.b } }` writes the
   key that IS `buildB.tickIntervalMs`. Ranking declared anchors above return
   shapes is correct for a READ through a receiver, but applied to this site it
   handed the write to a same-named module const that `buildB` never touches —
   a wrong edge — while the node the key actually defines was left with no
   writer at all. Both halves wrong from one rule applied to the wrong shape.

   Checked before every other rule, because it is evidence rather than ranking:
   the owner qualifier on the candidate id and the enclosing callable are the
   same symbol. Nothing outranks that.

2. THE TIER NO LONGER LIES.

   `workspace-unique` is a claim that exactly one node in the workspace carries
   the name — a fact about the graph, and the label a reader trusts most. An
   answer reached by FILTERING (tests down-ranked, return shapes down-ranked)
   is a weaker claim, and it was reported under the same label. The edge is
   unchanged; what it is allowed to say about itself is not. `narrowed` now
   counts these correctly too, since it keys off the tier.

WHAT I AM NOT DOING, and why. The review proposes dropping the same-file and
imported-file tiers "and keeping only genuine workspace-uniqueness". That would
revert the measured R2 result taking backend readers of `exitMinAtrMult` from
0 to 24. Workspace uniqueness was already measured too strict on that repo: the
field carries 26 Property definitions — 16 in one-off scripts, 7 in the
frontend, one in a test, and exactly one in the backend that reads it. Strict
uniqueness declines all 24.

The alternative suggestion — require the receiver to bind to the owning object —
has the same effect by another route: the population this pass exists for is the
untyped option bag, whose receiver binds to nothing. Requiring a binding turns
the pass off for its own use case. So the two demonstrated defects are fixed and
the capability around them is kept, at half confidence, naming its inference in
the reason string, and honoured only where `fieldFallbackOnMethodLookup` allows.

The R3-5 precision test needed rescoping rather than relaxing: it asserted that
EVERY edge to the contested field is a precise return-shape edge, which the
producer's own (correct, name-tier) write now violates. It asserts the reader
edges are precise and the producer's write binds to its own key — two different
claims reached two different ways, which is what the code now models.

* test(bench): re-baseline the JS/TS scope-capture fingerprints for this branch's capture additions

The `Cross-language scope-capture fingerprint + scaling guards` CI step was
failing on TypeScript and JavaScript, and it had been failing for the whole PR —
the branch changed both SCOPE queries without ever updating the guard's
baseline. It only surfaced now because a merge conflict had prevented CI from
running at all, so nothing reported it.

Re-baselined per the file's own instruction ("re-baseline intentionally on a
legitimate capture change"), and verified first rather than rubber-stamped. The
capture-name sets in both scope queries, diffed against `origin/main`:

  TypeScript  + @reference.read.identifier      (A2, bare-identifier reads)
              + @reference.type                 (R2-2, type references)
  JavaScript  + @reference.read.identifier      (A2)
              + @reference.read.destructured    (R2-1c)
              + @reference.write.property-key   (R2-1b)

Nothing removed on either side. A pure superset is the check that no EXISTING
capture moved — which is the failure mode a fingerprint guard exists to catch,
and the reason to look before regenerating.

Consistent everywhere else too: `capture_groups_small`/`_large` are unchanged
(4503/14403) because those measure the SYNTHETIC scaling source this branch does
not touch, so only the fixture-corpus number moves — 2097 -> 2338 across 21 new
lang-resolution fixtures, 146 -> 151 files. Scaling stayed linear and inside
budget (typescript 1.116, javascript 1.010, both < 1.5), so the added rules cost
no super-linear time. Prior and new hashes are recorded in the baseline note, as
every previous entry in that file does.

* test(bench): re-baseline the receiver-resolution drop guard for the new WRITE site kind

Second of the two bench guards that had been failing for the whole PR without
anyone seeing it — CI could not run while the branch was conflicted, so both
went unreported until the merge cleared.

The drift is a new site KIND, not a movement in an existing one:

    totalDropsAllKinds  129 -> 140
    bySiteKind          {call: 102, read: 27}
                     -> {call: 102, read: 27, write: 11}

`call` and `read` are byte-identical, which is the check that matters. This
branch added write-site captures the corpus never had — `@reference.write.
property-key` (R2-1b record construction) and the destructured-read rules — so
write sites reach receiver resolution for the first time, and 11 of them have a
receiver that does not resolve. A drop is the honest outcome for those; the
alternative is the name-inferred guess this series spent three rounds bounding.

Verified it is NOT caused by this session's review fixes before re-baselining:
removing the `memberNotOnShape` site-claim added in 69047086 and re-running gives
the identical 129 -> 140 / write: 11 drift, so the movement predates today and
belongs to the capture work, exactly as the arithmetic above says.

The sibling `scope-emission` guard still PASSES untouched, and the fingerprint
guard passes after 20a937f4 — so all three arms of the benchmarks job are green
locally.

* fix(routes): track boolean polarity in dispatch guards, so a negated condition cannot invent a route

Reproduced exactly as reported. `dispatch-guard.ts` refuses to inherit a verb
from an `if` whose `else` branch holds the comparison — the module's own doc
comment explains why: that branch runs precisely when the condition did NOT
hold, so attributing it is backwards. `!` is the same fact written as an
operator, and it was not handled. A stated invariant with half an
implementation, which is worse than an absent one, because the comment reads as
though it were covered.

Measured against the real extractor before fixing:

    if (!(pathname === '/api/admin'))                  ->  '' /api/admin   INVENTED
    if (!(req.method === 'GET') && pathname === '/x')  ->  GET /x          INVERTED
    if (!(req.method === 'POST' && pathname === '/w')) ->  POST /w         BOTH

And the review is right that this is not additive-only. Driven through the real
pipeline with a policy module that serves nothing plus a one-line route table,
the invented `GET /api/report` collected into `verbedUrls` and
`reconcileDispatchGuardRoutes` then EVICTED the true verb-less route for that
path. A false route deleted a real one. After the fix that repo yields exactly
one route, verb-less, path intact.

Parity, not presence: `!!x` is `x`, so counting negations and testing the parity
is the only rule that keeps a doubly-negated guard working. A negated VERB drops
to verb-less rather than dropping the route — `!(method === 'GET')` means every
method except GET, which no single value expresses, while the path evidence is
untouched. Applies to the regex arm too; `!/^\/api\/x$/.test(pathname)` had the
identical hole.

Deliberately NOT keeping the `statement_block` break from the suggested patch.
It is unreachable — the `!` in `if (!cond) { … }` lives in the condition, a
SIBLING of the block, never an ancestor of anything inside it, and the only
shape that puts a `!` above a block is an IIFE, which the function-boundary stop
catches first. Unreachable in the UNSAFE direction, too: breaking early
under-counts negations, and an under-count reads a negated guard as positive and
invents the route. Verified by mutation — with the break present, deleting it
fails nothing; the other three guards each fail a test when removed.

Six new cases, all previously absent (`grep -c '!(' ` over both test files was 0,
and the only negation covered was `!==`, the form that already worked).

* test(bench): re-baseline the emit-persistence byte-identity fingerprint for the isDetail column

The third bench guard this branch left red, and the one the earlier
rebaseline pass missed: the `benchmarks (GITNEXUS_BENCH)` job has never
succeeded once in eleven attempts, and since step 11 aborts the job, the
two steps after it — the streaming PDG-emit guard and the cross-language
pipeline benchmarks — have never executed at all.

    [emit-persistence --check] FAIL: byte-identity fingerprint drift
      (got 4ee15e74…, expected 69e9182a…)

Cause is this branch's own `isDetail` BOOLEAN on the Property table
(PROPERTY_SCHEMA), which `streamAllCSVsToDisk` writes as one more header
field and one more cell per Property row.

Verified header-only rather than regenerated on faith. Dumping every CSV
the bench emits on both `origin/main` and this branch and diffing them
per file (name, byte length, sha256): the file set is identical at 35
CSVs, 34 of the 35 are byte-identical, and the sole difference is
property.csv growing 68 -> 77 bytes as the header gains `,isDetail`. The
synthetic graph mints no Property nodes, so not one data row moved —
which is the thing this fingerprint exists to catch. Both timing gates
were green throughout (scaling_ratio 0.783 against a 1.8 budget,
elapsed_ms_large 229ms against the 1000ms backstop), so no throughput
claim is being rebaselined away.

Justification recorded in a `_rebaselined_<reason>` key, the convention
bench/scope-capture/baselines.json already sets, and the note now says so
explicitly so the next regeneration records its reasoning too.

* perf(processes): build each trace key once, not once per comparison

`deduplicateTraces` held its `join('->')` inside the `some()` callback, so
every already-kept trace had its key rebuilt from scratch against every
candidate: O(T*U) joins of O(depth * id-length) characters. The
allocation, not the substring scan, is what the pass spends its time on.

Nothing about breadth-first search made that safe. It only hid the cost by
keeping traces short — measured on this repo the walk averaged 4.3 steps
before D1 and 9.4 after, which roughly doubles both the number of
surviving traces and the length of every key, so the same quadratic that
was affordable under BFS is about six times the work under DFS. That is
the whole of the slowdown D1 was carrying; the depth-first walk itself is
cheaper than the queue it replaced (`pop()` against an O(frontier)
`shift()`), and its frontier is bounded by depth rather than by breadth.

Hoisting the join into a `uniqueKeys` array removes the multiplication.
Measured back to back on one host, 5 reps, 25k callables, production sink
path (main -> this branch before -> this branch after):

    deep_chain      876.8ms -> 1233.1ms -> 101.9ms
    mixed_cycles    731.4ms -> 1130.6ms -> 132.8ms
    shallow_wide    572.5ms ->  531.8ms ->  49.6ms

and on the real gitnexus/src corpus (11,490 symbols) process detection
goes 204ms -> 89ms against main, having been slower than main before.

Output is unchanged, which is the property that matters here: swapping the
file back and forth and diffing every non-timing field across all sixteen
shape x scale x sink-variant configurations gives no difference, and the
real corpus returns the same 936 processes / 4,648 steps either way. Sink
keys are pushed alongside the traces they belong to, so the comparison set
is the same set it always was.

* fix(processes): type the parse-output read as ParseOutput

The R3-6 sink read declared its own structural shape for the parse output
instead of naming `ParseOutput`, which made it the only one of the five
parse consumers in the repo not bound to the real type — cross-file.ts,
orm.ts, routes.ts and tools.ts all pass the type argument.

`getPhaseOutput` is a raw `as T` cast, so a local shape checks nothing at
runtime and only severs the compile-time link: renaming `allFetchCalls` on
`ParseOutput` would still compile here and silently detect zero sinks
forever. Verified with a real `tsc --noEmit --strict` run over exactly that
rename — the typed consumers error, this one did not. The runtime `.filter`
stays, since it is the only thing actually guarding the cast.

Also brings the phase docblock back in line with the deps array, which was
missing `structure` (pre-existing) and `parse` (added by this branch), and
records the two parse fields the phase now reads.

fix(resolution): resolve calls through a generic-typed field receiver in every language (#2833) (#2855)
* test(resolution): pin generic-typed field receivers across languages (#2833)

A field whose declared type carries a type argument (`repo: Repo<User>`)
emits zero CALLS edges — not a truncated chain, not an edge to the
interface declaration, nothing. This adds the cross-language matrix that
measures it, modelled on the #2807 inferred-field matrix: every language
runs the same two calls, one through a generic-typed field and one
through a non-generic control field, and each language is compared
against its OWN control row rather than an absolute edge count.

Measured state, pinned here as `known-gap` so the file is green on main
and flipping a row is a visible edit:

  affected    TypeScript, C#, C++, Python
  unaffected  Java, Kotlin, Go, Rust, Swift, Dart

The unaffected six erase type arguments at interpret time (Java's
`stripGeneric`, F41 #1928; Swift likewise). TypeScript, C# and Python
instead run a container ALLOW-LIST that returns the type ARGUMENT, so a
user-defined `Repo<User>` survives verbatim into a lookup that binds
nothing.

The `ts-local-vs-field` case is the bug in one file: `viaLocal` and
`viaParam` both resolve for the identical type, and only `viaField`
loses every edge — a bare name reaches Case 4 and its generic-aware
lookup, a dotted field receiver does not.

Negative controls pin what erasure must NOT do: an unbounded type
parameter denotes no declaration, and a C++ explicit specialization is a
different class from its primary template. The `Box2<T>` row pins a
PRE-EXISTING false edge (a workspace class named `T`) so it cannot later
be mistaken for fallout from this work.

* refactor(resolution): move resolveClassBindingForName to the shared walkers (#2833)

Pure relocation, no behaviour change: the generic-aware class lookup
moves from `passes/receiver-bound-calls.ts` to `scope/walkers.ts`, beside
the bare `findClassBindingInScope` it wraps. Its two existing callers —
`classifyReceiverOrigin` and Case 4 — import it from the new home and are
otherwise untouched.

The move is required rather than cosmetic: `receiver-bound-calls.ts`
already imports from `compound-receiver.ts`, so having the compound
receiver call into the pass would close an import cycle. `walkers.ts` is
the shared floor both already depend on.

Verified behaviour-neutral: the #2833 matrix is 44/44 identical before
and after, across all fifteen fixtures.

detect_changes attributes `resolveInheritanceBaseInScope`,
`resolveQualifiedInheritanceBase` and `EMPTY_BINDINGS` to this commit;
those are line-shift artifacts of inserting a function above them, and
their bodies are byte-identical.

* fix(resolution): type generic field receivers through the generic-aware lookup (#2833)

A field receiver is spelled `this.repo` — dotted — so it types through
the receiver-chain fold and the text cascade, both of which reach
`findClassBindingInScope`. That function has no notion of type arguments,
so a field declared `Repo<User>` resolved to nothing and the call site
emitted NO edge at all: not the interface declaration, not the
implementation fan-out, nothing. A local or parameter of the identical
type is a bare name, reaches Case 4 and its generic-aware
`resolveClassBindingForName`, and resolved fine. The bug was the
asymmetry, not the generics.

Three receiver-typing lookups now call the generic-aware helper instead:
`typeOfMemberOnClass`'s primary and module-hoist branches, and the
cascade's bare-identifier type-binding read. Every other one of the 38
`findClassBindingInScope` call sites is untouched — its own docstring
records that widening it globally suppresses the `?? otherResolver(...)`
fallbacks two dozen callers rely on, which would retarget inheritance
edges, and impact rates it CRITICAL with 12 direct dependents.

Order matters and is preserved: the helper tries the exact name, then an
arity- and token-exact match against `def.templateArguments`, and only
then falls back to the base name. Erasing first would collapse a C++
explicit specialization onto its primary template — `Vec<bool>` really is
a different class. A bare type parameter carries no type arguments, so it
never enters the generic branch and cannot be erased into a class that
happens to share its name.

Measured: TypeScript and C# generic-typed fields now emit exactly what
their non-generic control rows emit, primary plus interface-dispatch
fan-out. Java, Kotlin, Go, Rust, Swift and Dart are byte-identical. Both
type-parameter negative controls are unchanged. C++ and Python are still
open and stay pinned as known-gaps — they fail for different reasons and
get their own commits.

* fix(cpp,python): bind generic-typed member fields so their calls resolve (#2833)

Completes #2833 for the two languages the shared resolution change could
not reach. Each failed for its own reason, and both were found by
measurement rather than assumed.

C++ — a CAPTURE gap, not a resolution one. All three `field_declaration`
type-binding rules required `type: (type_identifier)`, so a member
declared `Repo<User> repo;` is a `template_type` and matched none of
them: the field got no type binding at all, and every call through it
lost its edge in both the bare and `this->` spellings. A LOCAL of the
identical type resolved the whole time, because the local declaration
rules gained their `template_type` variant long ago. Three mirrored
rules close it, one per declarator shape (plain, pointer, reference).
Written as separate patterns rather than one alternation: a node-type
alternation in a field position is a tree-sitter 0.21 hazard this repo
has been bitten by before.

Python — the bracket spelling never entered the generic branch. Its
`stripGeneric` is a container allow-list over `[...]` that returns the
type ARGUMENT (`list[User]` to `User`), so a user-defined `Repo[User]`
matched nothing and survived verbatim, and the shared lookup's generic
branch is gated on `<`. It now reduces a subscripted type neither
allow-list claims to its base name — the same rule Java and Swift
already apply to `<...>`. Deliberately the LAST resort: a container must
reach its own rule first, or `list[User]` would type the receiver as the
container and retarget every call in a for-loop chain. The as-written
spelling survives on `TypeRef.declaredSpelling`, which is what the fold's
index step reads.

Both are parse-time and land in the cached ParsedFile, so SCHEMA_BUMP
goes 45 -> 46 with its pin test. Verified free against origin/main; the
ledger in that file records three prior EXACT clashes, so re-check again
immediately before merge.

The matrix now covers the spellings real code writes, all measured: a
nullable generic, a bounded wildcard, a raw type, a nested generic and a
multi-argument one. None needed work beyond the shared lookup, which is
the evidence that base-name erasure is the right primitive. The C++
specialization control now asserts what it was written for:
`Vec<bool>.save` and `Vec.save` are DIFFERENT target ids, so the
arity/token match still wins over erasure.

scope-capture is byte-identical for cpp and c, so no rebaseline — the
bench corpus contains no generic-typed member field, which is worth its
own coverage issue.

Two pre-existing gaps were measured and are deliberately NOT fixed here,
because in both cases the language's own non-generic CONTROL row fails
identically: C++ `this->field.m()` emits nothing, and JavaScript/PHP
docblock-declared field types bind nothing at all.

* fix(python): do not reduce containers or typing special forms to a base name (#2833)

Review finding on this branch's own Python change, caught by probing the
interpreter directly rather than by reading it.

The base-name reduction was reached by FALLTHROUGH: "neither container rule
matched" was treated as "not a container". It is not, and two measured
shapes proved it:

  dict[str, list[User]]   ->  dict          (was: the annotation, intact)
  Dict[str, Repo[User]]   ->  Dict
  Callable[[int], User]   ->  Callable
  Literal["a"]            ->  Literal
  Union[A, B]             ->  Union
  tuple[int, ...]         ->  tuple

The dict rule's value group cannot span a nested `]`, so a nested value
declines and falls through — and the dict rule's own comment says that
shape is deliberately "left for a downstream strip pass". Collapsing it to
`dict` destroyed the value type instead. The typing SPECIAL FORMS are worse:
`Callable`, `Literal`, `Annotated` and `Union` are not classes, and reducing
them to a bare name binds any workspace class that happens to share it —
a fabricated edge, which is strictly worse than the missing edge #2833 set
out to fix, and those names are ordinary enough for a real codebase to
declare.

Reduction is now guarded by an explicit deny set covering the containers the
two allow-lists already own and the typing special forms. Everything named
there keeps its as-written text and resolves exactly as it did before #2833.

`arr[0]` also reduces to `arr` in isolation, but that is unreachable and is
now documented as such: every Python `@type-binding.type` capture is a
`(type)`, `(identifier)`, `(attribute)` or `(dotted_name)` node, so a
subscripted VALUE expression never reaches the interpreter.

Pinned by a new unit test that asserts all four groups — user generic
reduces, container reduces to its ELEMENT, declined container shape stays
intact, special form untouched. Reverting the deny set fails three of its
five cases.

Also corrects `resolveClassBindingForName`'s docstring, which this branch
had made false: it claimed only `classifyReceiverOrigin` passes the
decoration stripper, while the three receiver-typing lookups in
compound-receiver.ts now pass it too.

* fix(resolution): rank base-name candidates lexically and refuse arg-pinned defs (#2833)

Review of #2855 found that this PR turned a MISSING C++ edge into a
CONFIDENTLY WRONG one — the direction this subsystem calls unrecoverable.

`resolveClassBindingForName` ended with an unguarded base-name fallback
that returned the first same-named class the scope chain reached. A C++
primary template carries `templateArguments === undefined`, so it can
never satisfy the exact-args branch, and every non-specialized
instantiation fell through to that fallback. Measured through the real
pipeline: with the primary forward-declared and the specialization
defined first, `Vec<int> vi; vi.save()` emitted `Vec<bool>::save`.
Declaring the primary first gave the correct target — selection was
SOURCE-ORDER DEPENDENT. Two more triggers behaved the same way: a
partial specialization (`Vec<int*>` against `Vec<T*>`), and lexical
shadowing between a global `Box<bool>` and a namespaced `N::Box<bool>`.

Two changes, neither of which is any of the three remediations the
review proposed — each was rejected on measured evidence:

- Exact-argument matching is now LEXICAL-FIRST. Candidates come from the
  scope chain, and the workspace-wide qualified-name bucket is consulted
  only when the chain produced no exact match, so cross-file
  specializations still bind.
- The base-name route refuses a definition that pinned its own template
  arguments: if the fallback's answer carries `templateArguments`, the
  visible candidates are re-decided with those removed — exactly one, or
  decline.

Why not the filed options. "If specializations exist and none matches
exactly, return undefined" deletes a green committed row
(`neg-cpp-specialization/runInt` legitimately resolves to the primary).
"Resolve all defs for the base name, return only on exactly one" deletes
a working edge for C# `partial class Repo<T>` split across files — two
unspecialized defs under one name is legitimate, and
`QualifiedNameIndex`'s own docstring names that case. Preferring the
primary alone fixes nothing about shadowing, which is a ranking bug.

The guard is expressed as `carriesOwnTemplateArguments`, not as
"specialization", so shared pipeline code still names no language
(AGENTS.md R6). It can only fire where a declared name carries concrete
arguments — measured `undefined` for `class Repo<T>` in TypeScript and
C# and for a C++ primary template — so the blast radius is bounded to
C++-style specializations.

Partial-specialization SELECTION is deliberately not implemented:
choosing `Vec<T*>` for `Vec<int*>` needs template-argument deduction,
which is a semantics expansion and cannot live in language-neutral
shared code. The source-order dependence is what is fixed; the answer is
now deterministically the primary.

Also in this commit: dropped an unreachable `?? []` (QualifiedNameIndex
returns a frozen empty array on miss by contract) whose comment was
wrong on both clauses; made the docstring true about argument ERASURE
being what widens what binds, rather than only the decoration stripper;
and corrected a stale pointer that still placed
`resolveClassBindingForName` in `receiver-bound-calls`.

`findClassBindingInScope` itself is untouched — 38 call sites, CRITICAL.

Verified: matrix 56/56, cpp.test.ts 334, unit scope-resolution 1505.
Mutation proof: reverting this file fails the three trigger cases and
passes the non-regression cases; restoring it passes all five.

* fix(python): close the deny-set drift axis by case-folding, not by vigilance (#2833)

Review of #2855 found `NOT_A_USER_GENERIC` was a closed list over an
open universe: four review lanes each escaped it with a DIFFERENT set of
names. `Deque` was the sharpest — its lowercase twin `deque` was already
listed, so the omission was an internal inconsistency rather than a
judgement call, and with a workspace `class Deque` present
`self.dq: Deque[User]` fabricated a `Deque.appendleft` edge.

The structural cause is PEP 585: nearly every container has two
spellings differing only in case (`deque`/`typing.Deque`,
`frozenset`/`FrozenSet`). Exact matching forced every pair to be listed
twice, so any half-pair was a silent escape. The deny lookup is now
CASE-FOLDED, which closes that axis by construction — `Deque` becomes
impossible rather than remembered.

`SINGLE_ARG_CONTAINERS` and `MAPPING_CONTAINERS` are now the single
source of truth: they build the two container regexes (verified
byte-identical `.source` and `.flags`, so zero behaviour change) and
feed the property test. The deny set is re-scoped to a closed, auditable
universe — the documented Python stdlib type-system surface — and grew
39 -> 65 concepts: the `collections.abc` views, `contextlib` managers,
`re.Pattern`/`Match`, the `IO` family, ordinary-named stdlib generics
(`Queue`, `Task`, `Future`, `PathLike`), the remaining typing special
forms, and the generic machinery (`Generic`, `Protocol`, `TypeVar`...).

Third-party generics (`Mapped`, `QuerySet`, `Model`) are deliberately
NOT added and are pinned as a decision: that universe is open,
enumerating it only chases the last escape, and declining `Model` would
cost real edges in the many projects that declare one.

The review's suggested property test — derive the names from the
`single`/`dict` regex sources — would NOT have caught `Deque`: `deque`
appears in neither regex, only in the deny set. Both properties are
implemented, since they catch different drift.

The unit test was also TAUTOLOGICAL: it asserted members OF the deny
set, so it structurally could not detect an omission. It now asserts
case-fold closure and PEP 585 alias coverage, and the capture fixture
drops its `as unknown as` cast for the fully-typed helper pattern the
sibling `java-interpret.test.ts` already uses.

Still at interpret time, so no further SCHEMA_BUMP (already 45 -> 46).
Proving the base is a class the FILE can see — the real fix for the
remaining exposure, since `findClassBindingInScope` binds any name with
exactly one workspace def regardless of scope or imports — is a
follow-up, not reachable from this file.

Mutation proof: restoring HEAD's deny-set contents and exact-match
lookup fails four assertions including the `Deque` pair, with the
pre-existing guard rows still passing; restoring gives 125/125.

* fix(cpp): capture qualified generic member fields, and make the bench gate see them (#2833)

Review of #2855 found that the three `field_declaration` rules this PR
added only matched a DIRECT `template_type`, so the common real-world
spelling still bound nothing: `std::vector<Item> items;`,
`ns::Repo<User> r;` and `std::unique_ptr<Repo> p;` parse as a
`qualified_identifier` WRAPPING a `template_type`. "C++ fixed" was
overstated.

Six new patterns — three declarator shapes (plain, pointer, reference)
by two qualifier depths — written as separate patterns rather than one
alternation, keeping the tree-sitter 0.21 field-position discipline the
existing rules follow.

The design choice was measured, not assumed. Codex suggested preserving
the full qualified spelling and normalizing `::`; preserving resolves
NOTHING, because `findClassBindingInScope`'s dotted-tail fallback splits
on `.` while C++ writes `::`, and `ns::Repo` is not an index key either
(C++ emits no `@declaration.qualified_name`). Measured: `ns::Repo<User>`
resolves to nothing, `ns.Repo<User>` resolves to `Repo`. Since a
tree-sitter capture is a NODE and not synthesized text, the only lever
is which node to capture — so `@type-binding.type` goes on the INNER
`template_type`, dropping the qualifier and landing on the same
single-match-or-decline path the bare spelling already takes.

Qualifier depth 3+ (`a:🅱️:c::Repo<User>`) remains uncaptured. Stated as
a limit and pinned by a test row, not claimed as fixed.

The bench blindness the review identified is also closed. The
`scope-capture` C++ corpus contained ZERO template-typed member fields —
confirmed a fourth way by applying six demonstrably behaviour-changing
patterns and getting a byte-identical fingerprint. The corpus now
carries generic and qualified-generic members, and the gate is load
bearing for the first time: three states that all hashed to 856d02f3
before now differ (pre-#2833 0e7cbda7, +this PR's 3 rules de07d8b5,
+these 6 rules bd47c82d). Rebaselined for cpp only; c is unchanged.
Histogram diff: only 5 tags move with the fields, each by exactly +40
(20 entities x 2), and every `@reference.*` count is unchanged.

Over-match is preserved: 20 shapes still produce no field capture,
including the 8 original method/pointer/reference/function-pointer/
using/typedef/friend/operator forms plus their `std::`- and
`a:🅱️:`-qualified variants.

Not fixed here, deliberately: NON-generic qualified fields
(`ns::Address addr;`, `std::string name;`) still capture nothing.
Closing that needs six more patterns and would newly bind every
`std::string`/`std::mutex` member repo-wide, changing edges far outside
#2833. Separate issue.

The template-template-parameter hazard the review filed against these
rules is NOT capture-side: a tree-sitter query has no scope knowledge,
so it cannot know `Map` is bound by the enclosing `template <...>`
header, and the PRE-EXISTING `type: (type_identifier)` rule already
captures a bare `T item;` and erases it the same way. It is handled by
the lexical ranking in `walkers.ts` in this series.

Mutation proof: reverting this file fails 9 of 32 assertions (all eight
qualified spellings return no capture) while every over-match negative
still passes; restoring gives ALL PASS. Bench `--check` passes for all
15 languages.

* test(resolution): pin specialization order, shadowing and the untested spellings (#2833)

Grows the generic-field matrix 56 -> 114 tests, closing every coverage
gap the #2855 review named and turning the fix-agents' scratch evidence
into permanent rows.

The rows that discriminate against the resolver fix (they fail if
`walkers.ts` is reverted):

- C++ specialization must not depend on DECLARATION ORDER: the
  forward-declared-primary/specialization-first arrangement must land on
  the primary, same as the mirror arrangement. Plus a cross-case
  property asserting the two independently built fixtures agree.
- Partial specialization is deterministic in both orders. The note says
  explicitly that selecting `Vec<T*>` would need argument deduction and
  that flipping this row later is a deliberate expansion, not a
  regression fix.
- Lexical shadowing: the namespace-local `N::Box<bool>` wins for a field
  inside `N`, and the global specialization wins at global scope.

The NON-REGRESSION rows are load-bearing — they are why two of the three
proposed remediations were rejected: cross-file C++ specialization
binding, and C# `partial class Repo<T>` split across two files with the
field in a third (two legitimate unspecialized defs under one name).

Coverage the review found missing: C++ pointer and reference generic
fields (two of this PR's three original rules had ZERO coverage); all
six qualified patterns plus the depth-3 boundary pinned as empty;
TS/C# multi-arg container collision; an anti-vacuity sibling for
`neg-bounded-type-parameter`; Swift/Dart rows restructured so the
ANNOTATION is the only possible source (the old rows gave the field an
initializer of the same generic type and could not tell which resolved);
and cross-file, inheritance/MRO, import-alias, static-member and the
TypeScript module-hoist branch.

Six things were measured and pinned AS MEASURED rather than asserted as
wishes, each flagged in its row note: a static/class-level member emits
nothing for generic AND non-generic alike (a static gap, not a generics
one); a cross-file C++ primary template does not bind while the
cross-file specialization does; `std::unique_ptr<Payload>` types to
`unique_ptr` rather than `Payload` (smart-pointer transparency is not
applied on the qualified path); two same-named C++ specializations in
one file collapse to one node id; and the container-name collision
(`Map<string, User>` binding a workspace `class Map`) is recorded as
INTENDED, since the annotation does name that class.

The `new Set(...)` dedup was kept rather than narrowed: a per-case
surplus-edge sweep measured ZERO duplicate edges anywhere in this file,
Swift included, so the quirk that justified a blanket dedup does not
reproduce. The sweep now pins zero surplus per case, so a real
double-emit fails instead of being absorbed.

The file is deliberately NOT split: four assertions compare cases
against each other, cost is linear in cases, and the 1,800,000 ms
`beforeAll` is kept because the same run measured 271-428 s depending on
host load — a tighter bound converts contention into a red suite. The
reasoning is recorded in the file header.

Also corrects the SCHEMA_BUMP pin-test title, which still said (#2766).

Mutation proof: reverting `walkers.ts` fails exactly the five order and
shadowing assertions and passes the other 109; restoring gives 114/114.

* feat(resolution): capture declared type parameters so a type variable is not a class (#2833)

Three review findings were blocked on one missing fact. `templateArguments`
records the arguments a declaration was written AGAINST (`struct Vec<bool>`);
nothing recorded the parameter list a declaration DECLARES (`template <class T>`,
`class Box<T extends Repo>`). So the resolver could not tell a type variable
from a class, and:

- `class Box2<T> { t: T }` beside a workspace `class T` emitted a FALSE edge
  `run2 -> T.foo`. `T` carries no type arguments, so it never entered the
  generic branch — the plain lookup simply bound a same-named class. The
  lexical grounding added elsewhere in this series cannot help, because
  `export class T` IS lexically bound.
- `class Box<T extends Repo> { t: T }` resolved to nothing: no recorded bound
  to resolve through.
- A full specialization `template<> struct Vec<T*>` and a partial
  `template<class T> struct Vec<T*>` were byte-identical (`['T*']`).

`SymbolDefinition.typeParameters` now records `{ name, bound? }` in declaration
order (substitution is positional). `bound` is kept verbatim and un-split, so
`Repo & Closeable` stays whole; ABSENT means UNKNOWN, never "unbounded", which
is what keeps unconverted languages behaving exactly as before.

Transport is the raw parameter-list node via `@declaration.type-parameters`,
read by a language-neutral parser that recognizes TOKENS, not languages:
`extends`/`:` introduce a bound, the name is the trailing identifier, so
`class T`, `typename T`, `in T`, `out T`, `reified T` and `class... Ts` are one
rule. Populated for TypeScript, C++, Java, Kotlin, C# and Rust. JavaScript, C,
COBOL, PHP and Ruby have no declared type parameters to capture; Go and Python
spell them with SQUARE brackets, which this parser deliberately rejects as
ambiguous against subscript and array spellings (Go already has a working
main-thread sidecar in this series); Dart and Swift are straightforward
follow-ups.

Two latent hazards found and closed on the way:

- The new capture was not in `KNOWN_SUB_TAGS`, so it could out-span its own
  declaration and become the anchor — silently DROPPING the whole class def.
- A templated C++ struct matches both the standalone and `template_declaration`
  patterns, minting two defs under one id, and only one twin could see the
  parameter list. `buildDefIndex` is first-write-wins, so MATCH ORDER decided
  whether `Vec` remembered `T`. A narrow duplicate-declaration backfill gives
  both twins the list.

Also fixed by its own test: a Rust lifetime `'a` parsed as a parameter named
`a`, which would have shadowed a real class.

Parse-time output lands in the cached ParsedFile, so SCHEMA_BUMP goes 46 -> 47.
Re-checked against origin/main at write time: main is on 45; 46 was taken by
this same branch, and a warm cache stamped 46 carries ParsedFiles with no
`typeParameters` at all.

The csharp and rust capture goldens were regenerated with the tests' own
documented `UPDATE_GOLDEN=1`; only digests moved, no captureGroups.

* fix(resolution): ground erased base names, and stop a class name from being enough (#2833)

The review's central risk was that this PR converts MISSING edges into
CONFIDENTLY WRONG ones. Base-name erasure (`Repo<User>` -> `Repo`,
`Repo[User]` -> `Repo`) bound through a workspace-wide qualified-name
fallback that consults NO scope, NO import and NO module — it bound any name
with exactly one workspace def. That is why a Python `Mapped[User]` could bind
an unrelated `class Mapped`, and why the language deny lists were papering
over an open universe.

`resolveErasedBaseName` now admits an erased base on one of four grounds,
strongest first: the scope chain binds it; the declaration is in the SAME
FILE; the index proves the name is a template family; or the file binds no
cross-file class at all, so its silence is no evidence. The last ground fails
toward permissive on purpose — every way it can be wrong costs a wrong edge
that already existed, never a working one.

Two measurements drove that design and refuted the simpler rule. A C++
`#include` materializes NO binding whatever, and C# resolves cross-namespace
without `using` through the index — so a pure "require lexical grounding" rule
would have deleted every cross-file C++ generic member. Both are now pinned.

Python erases at CAPTURE time, so by resolution there is no `<` and the
grounded route was never entered. `erasedTypeApplication` rebuilds the
application from `TypeRef.declaredSpelling` — strictly: the raw name must be
the base and the argument list the whole balanced remainder, so `User[]`,
`vector<Item>` and `Repo<User>?` decline and behave exactly as before.

Closing it took finding FOUR emitters, not one. Three were in Case 4; the
fourth was `emitReferencesViaLookup` re-emitting the refused edge from the
pre-resolved reference index, which needed the site marked handled with a
recorded `receiver-unresolved`. A fifth lived in the text cascade: a declined
fold falls THROUGH by design, and the cascade held its own ungrounded copy of
the member-typing lookup. This file typed a receiver from a `TypeRef` in five
places and the PR had wired three; all five now go through one
`classOfDeclaredType`.

Also here, from the same review:

- Type parameters no longer bind a same-named class (uses the new
  `typeParameters`), and a BOUNDED parameter resolves through its bound.
- A cross-file C++ PRIMARY template now binds: a ranking bug, not a capture
  one — the index fallback needs exactly one candidate and `Vec` held two, so
  removing the argument-pinned declaration leaves one.
- `this->field.m()` resolved to nothing for generic AND non-generic alike. A
  language that declares `this` IS the enclosing class
  (`resolveThisViaEnclosingClass`) synthesizes no `this` typeBinding, so a
  chain whose BASE is `this` could never seed its head. Reading the provider
  flag keeps the rule language-free.
- Class-level (static) member receivers emit nothing in TypeScript and Kotlin
  — for the non-generic control too. Case 6 types them from the DEF side
  (`isStatic` + `declaredType` on the field node), which needs no capture
  change; the target lookup stays the ordinary instance walk, so a static
  field HOLDING an instance still binds an instance method and a genuine
  static call is untouched.

Partial-specialization SELECTION is deliberately not implemented: it needs
argument deduction against a parameter list, and full C++ partial ordering is
a real algorithm with no measured driving case. The discriminator now exists
if someone wants it.

* fix(cpp,js,php,go): close the remaining per-language generic-field gaps (#2833)

Four language gaps the review measured, each with a different cause.

**C++ qualified member fields.** `std::vector<Item> items;`, `ns::Repo<User> r;`
and `ns::Address addr;` captured NOTHING: every field rule required the type
node to BE a `type_identifier` or `template_type`, and a qualified member type
is neither — tree-sitter wraps both in a `qualified_identifier`. Three
depth-agnostic rules (one per declarator shape) now match the outer node, which
also REMOVES the depth boundary rather than raising it: depths 1-4 capture,
generic and non-generic alike.

Preserving the qualifier resolves nothing — measured: `ns::Repo<User>` binds
neither way, because the dotted-tail fallback splits on `.` while C++ writes
`::`, and `ns::Repo` is not an index key. Since a capture is a NODE and not
synthesized text, the qualifier is dropped in `interpret.ts` by a top-level-only
`::` split, so `std::vector<std::string>` reduces to `vector<std::string>`, not
`string`.

Measured cost of the non-generic half, which was the reason to hesitate: field
captures go 8 -> 32 across the C++ bench corpus, but the resolution-level census
over those 13 repos is 32 CALLS edges before and 32 after, BYTE-IDENTICAL. It
fabricates only where a workspace class shares a std name (`class string` beside
`std::string name;`), which is the same accepted policy the already-landed
qualified-generic rules carry, pinned in the matrix as intended.

**JavaScript `@type {Repo<User>}` and PHP `@var Repo<User>`.** Neither bound a
field type — and neither did the NON-generic control, so this was a docblock gap
rather than a generics one. PHP needed TWO captures, not one: with only the type
binding, `$this->repo->save()` resolved until a second class declared `save` and
then went unresolved, because narrowing a same-named method needs the receiver's
member owned. Generics do NOT come free in PHP — `normalizePhpType('Repo<User>')`
returns `'User'` by the container-element convention, so passing the raw spelling
through would have emitted `User::save`; type arguments are erased at capture
instead. In JavaScript they DO come free, verified byte-identical to the
TypeScript control. Both decline what they cannot prove: arrays, `list<User>`,
unions, `Promise`/`Array` wrappers (via an exported predicate rather than a
copied name list), statics, and any property that already has a native type.

**Go generic interfaces.** `UserRepo` genuinely DOES implement `Repo[User]` —
the spec says a generic type must be instantiated, that instantiation
substitutes type arguments and yields a new non-generic type, and that a type
implements an interface when it is in its type set. So the old behaviour was a
FALSE NEGATIVE and the matrix note calling it "already correct" was wrong.
Satisfaction is now checked against POSITIONALLY SUBSTITUTED method sets, so
`Repo[Order]` does not match a `Save(x User)` implementor — substitution, not
erasure. #2829's exact method-set model is untouched: pointer receivers still
follow MS(*T), unexported names stay package-scoped, the declaration's own
method set is still checked first, and the harvest is gated so a repo with no
generic interface never runs it. `go.test.ts` is unchanged at 296 passing.

* test(resolution): pin every fix from the review, 114 -> 155 rows (#2833)

Eight rows in this matrix pinned gaps that the fixes in this series close, so
each asserted the opposite of the new truth. All eight are flipped, and the
prose describing them as open gaps is corrected. Nine new cases cover the fixes
that would otherwise have shipped unpinned.

Flipped, each measured: the type-parameter FALSE edge (`run2`) is gone; a
bounded parameter now resolves through its bound with fan-out; the cross-file
C++ primary binds; the C++ qualifier depth boundary is removed rather than
raised; Go gains its two structural implementors and JOINS the paired sweep,
which had quietly excluded it — that exclusion was the taxonomy admitting a bug;
and both static-member rows resolve.

Added: JS `@type` and PHP `@var` docblock fields with three PHP declines; a
Kotlin `companion object` receiver (given an INTERFACE control so the paired
sweep can check it, which `ts-reach-shapes` cannot — its two sides are not
count-comparable); the Python third-party grounding refusal plus the ground that
still ADMITS, so an empty row can never be read as "erased names never resolve";
the four mirrors that would break if grounding were tightened (same-file and
imported Python, a C++ `#include`, C# cross-namespace without `using`); C++
qualified non-generic fields including the fabrication policy and its absence
case; `this->field.m()` for generic and non-generic with bare controls; and a Go
negative proving substitution is positional, not erasure.

Three shapes are pinned AS MEASURED with notes saying they are deliberate limits
so nobody "fixes" them by accident: C++ partial-specialization selection is
deterministically the primary (real selection needs argument deduction);
`std::unique_ptr<T>` types to the pointer, not the pointee (`.` and `->` are
indistinguishable to the resolver, so transparency would trade a recoverable
miss for a confident wrong edge); and two same-named C++ specializations in one
file collapse to one node id, which is why the shadowing fixture uses two files.

One row pins a REMAINING wrong edge rather than hiding it: `m.inner.ping()` on
a `Mapped[User]` head still binds the unrelated workspace class, while the
one-segment-shallower `m.save(u)` correctly declines. The obvious one-line guard
was written and MEASURED not to close it, so the surviving route is elsewhere
and wants its own diagnosis — a broader refusal would change chain-head
resolution for every language without pinning the shape it is meant to fix.

`bench/scope-capture` is rebaselined for the six languages whose captures moved,
regenerated from a fresh measurement rather than pasted; `--check` passes for all
15.

* perf(resolution): remove three measured hot-path regressions this series added (#2833)

A quality pass over the #2833 series found three performance defects it had
introduced, all measured, plus dead code and stale docs from six agents having
appended to the same files across four rounds. No behaviour change: the
resolver suite is identical before and after, and every scope-capture
fingerprint is byte-identical.

**An accidental quadratic in Go instantiation harvesting.** `collectGoInstantiations`
calls `record()` for every type binding and every declared, return and parameter
type in every Go file, and the `includes('[')` gate does not filter Go's most
common types — `map[string]string`, `[]map[string]*v1.Pod` and
`map[string]map[string]int` all produce a `map` candidate. Each false base then
failed a full scope-chain walk and fell through to a LINEAR SCAN OF EVERY
INTERFACE IN THE PROGRAM, with no dedupe on the spelling, so the same
`map[string]string` written 10,000 times paid 10,000 scans. Now a
qualified-name index built in `buildDetectionIndexes` (one probe, ambiguity
semantics preserved exactly) plus a per-scope base memo:

    8,000 interfaces / 80,000 spellings:  6,662 ms -> 104 ms   (64x)

`resolveEmbeddedInterface` held a byte-identical copy of that scan and now
shares the helper. `GoInstantiation` was a single-field wrapper and collapses
to the array it wrapped; its two parallel maps fold into one whose inner key IS
the dedupe. `candidateStructIdsFor` was rebuilt per instantiation although
every substituted method set has the same key set — hoisted, and materialized,
because one branch returned a live iterator that would have yielded nothing on
a second pass.

**`scanForCrossFileClass` asked a name-keyed question that needs no name key.**
It answered "does this file bind any cross-file class" by probing every
accessible namespace once PER NAME. It now iterates the channels directly,
taking whichever side is smaller so a large namespace table cannot reintroduce
the product. Predicate and early exit preserved:

    5,000 module names x 1,000 namespaces:  159.0 ms -> 1.2 ms   (132x)

**A duplicated scope walk on every generic receiver.** `resolveClassBindingForName`
computed the lexical candidate list, then `resolveErasedBaseName` recomputed
the identical `findAllBindingsInScope`. Computed once and passed:

    receiver at depth 8:  5,617 ns -> 3,091 ns   (-45%)

**A whole extra AST traversal per JavaScript and PHP file.** The docblock
synthesis passes each added a full tree walk to find one node kind — the ninth
in the JS emitter, the third in PHP. `node.namedChildren` materializes a
wrapper array across the N-API boundary for every node, so one added pass cost
1.9x what parsing the entire file costs. Folded into the existing walks as one
more node kind; capture output is byte-identical and every fingerprint is
unchanged. Total emit time per file drops 4-7%.

Hygiene, all verified stale rather than assumed:

- `receiverOriginOpts` passed `resolveThisViaEnclosingClass`, which
  `classifyReceiverOrigin` never reads — the "both hooks" comment above it is
  true again.
- The `stripDecoration` docstring's caller roll-call claimed the only
  edge-emitting caller "emits no edge and can only change a diagnostic label".
  Case 6 passes it and does emit edges. Replaced the roll-call with the rule;
  six rounds each appending a name to a list is how it went wrong.
- A Python comment described the resolution-time grounding as a follow-up that
  "this parse-time pass cannot do" — it landed in this same branch and is
  pinned by `py-erased-grounding`.
- `classOfDeclaredType` took a `scopeId` all five callers derived from the
  `TypeRef` they also passed. Dropped, so "these five are the same call" is
  enforced rather than asserted.
- Three exports with no consumer outside their own file.
- PHP had three copies of one preceding-comment sibling walk and two regexes
  for one tag, so a fix to either reader of `@var` would land on one and not
  the other — the symptom being a field typed differently from its own foreach
  element type. One walk, one regex.

Tests: the new matrix leaked a fixture repo per case; it now carries the
sibling suite's `cleanupTempDirSync` and the Windows EBUSY reasoning that goes
with it. `PAIRED` was a second hand-maintained list and 19 of 41 cases had
silently fallen out of it — it is derived from the cases now, with a new
assertion that each case is either swept as a pair or carries a written reason
it is not. That recovered one genuine omission (`php-typed-property`).

* test(bench): rebaseline receiver-resolution for the #2833 this-> fix

The `Receiver-resolution drop guards` CI step failed on this branch:

  shapeArm.cpp.fieldReceiverCall:  "INVISIBLE-GAP" -> "RESOLVES"
  shapeArm.cpp.decoratedFieldType: "INVISIBLE-GAP" -> "RESOLVES"

Both are the intended improvement. The guard is exact-match by design —
the drop count cannot move without a deliberate rebaseline, and the
rebaseline path demands the movement be explained — so this records the
two shape flips and leaves the call-drop count arm untouched.

BASELINE.md still claimed `this->repo.save()` and `this->repo->save()`
were INVISIBLE-GAP. That is now false: the `resolveThisViaEnclosingClass`
head seed added in this PR resolves both. Also notes what the control
established — this was never a generics gap, since the non-generic
control failed identically before the fix.

* docs(parse-cache): narrow the SCHEMA_BUMP ledger to what the bump delivers

The ledger claimed a warm cache would make "the whole fix ... a silent
no-op on every incremental analyze". That overstates the constant. The
bump invalidates the PARSE half; whether the re-parsed captures reach the
graph is gated separately and does not move:

  - `isIncremental` (core/run-analyze.ts) tests `!options.force`, an
    existing meta, `!schemaFingerprintMismatch(...)`, feature parity,
    non-empty `fileHashes` and a git repo. SCHEMA_BUMP is in none of them.
  - the incremental branch writes back only `hashDiff.toWrite` and logs
    the rest as "unchanged file rows preserved".
  - SCHEMA_FINGERPRINT hashes node/relation DDL, untouched here, so it is
    byte-identical and moves nothing either.

So an incremental analyze re-parses an unchanged file correctly but keeps
its existing rows; the new edges land on the next full rebuild. That is
the pre-existing contract for every capture change, not a regression in
this PR — but the comment should not promise more than it delivers.

Comment only; no behavior change. SCHEMA_BUMP stays 48.

fix(python): resolve calls through an unaliased dotted namespace import (#2826) (#2828)
* fix(python): resolve calls through an unaliased dotted namespace import (#2826)

`import pkg.db` followed by `pkg.db.session_scope()` emitted no CALLS edge,
while all three sibling spellings resolved. In a codebase whose style guide
mandates absolute imports this is close to the only cross-module call form
used, so `impact()` reported `impactedCount: 0, risk: LOW, epistemic: exact`
for functions with dozens of real callers — a dropped caller reading as a
verified all-clear.

The resolution path was never missing; one map was keyed on the wrong half of
the import. `interpretPythonImport`'s plain arm splits `import pkg.db` into
`localName: 'pkg'` (the name Python actually binds) and
`importedName: 'pkg.db'`, and finalize carries both onto the edge as
`localName` / `targetExportedName`. `collectNamespaceTargets` keyed only on
`localName`, but the receiver text captured at the call site is the whole
dotted path — Python's query binds the attribute's `object` field with a
wildcard, so `pkg.db.session_scope()` yields the receiver `pkg.db`. Case 0
declines it (a module is not a class) and falls through, Case 1 looks up
`pkg.db` and misses, and Case 1.5 needs `resolveQualifiedReceiverMember`,
which only the C++ provider implements. The site drops silently.

Key the map on the dotted import path as well — gated on a provider opt-in,
not on the edge shape. The shape alone cannot decide it: Swift's
`import Foo.Bar` produces the identical pair (`localName: 'Foo'`,
`targetExportedName: 'Foo.Bar'`), but there the FIRST segment is the resolved
target and `Foo.Bar` names a nested type. Minting a key for it would hand
`resolveConstructionExpressionClass` an authoritative namespace — that branch
deliberately does not fall through on a miss — and break `Foo.Bar(x)`
construction that resolves correctly today. Hence
`ScopeResolver.namespaceReceiverIncludesImportPath`, which only Python sets.

The root-segment check on the added key does real work: `import pkg.db as pdb`
binds only `pdb`, so writing `pkg.db.f()` there is a NameError, and its edge
(localName `pdb`, path `pkg.db`) is correctly rejected.

Two same-package imports stay separate — `import pkg.db` + `import pkg.cache`
key `pkg.db` and `pkg.cache` independently, so neither call can land in the
other's module; the shared `pkg` bucket keeps its existing ambiguity rather
than gaining any.

Tests: five integration rows (the issue's own repro, the three sibling
spellings as controls, non-crossing two-package imports, a three-segment
receiver, and dotted construction) plus a unit pin on the keying rule that
asserts a Swift-shaped edge mints nothing. All five integration rows fail on
the pre-fix tree; the controls pass on both, which is what makes them
controls. Resolver integration suite 3024 passed / 1 skipped / 0 failed;
scope-resolution unit suite 1446 passed.

This changes what the resolver produces, not how it is stored — no schema or
version constant applies, and an existing index needs a re-analyze to show
the new edges.

* fix(resolution): shadow-test a dotted namespace key by its root segment (#2826)

`isNamespaceNameShadowed` walks the scope chain looking for a binding, type
binding, lexical name, or owned def named exactly `namespaceName`. Once a
namespace key can be a dotted import path, that string never matches anything:
`import pkg.db` binds `pkg`, so a local `pkg = Decoy()` shadows the import,
but the guard was asked about `pkg.db` and answered "not shadowed".

The consequence is not a missed edge but a wrong one. The caller treats a
verified namespace as authoritative and deliberately does not fall through to
the workspace-wide simple-name heuristics, so an unguarded shadowed receiver
resolves construction against the imported module instead of the local value.

Test the first dot-separated segment instead. Single-segment names are
unaffected — their root is themselves — so every pre-existing row keeps its
behaviour.

This ships with the key that first routes a dotted name into the guard rather
than after it: the previous commit is what makes the defect reachable.

The new pin fails on the pre-fix guard (verified by reverting the four
comparisons and re-running: 1 failed / 5 passed), so it discriminates rather
than merely passing.

* test(python): pin the callee name on the dotted-construction row (#2826)

The row asserted only that `builds` reached `pkg/db.py`. That module also
exports `session_scope`, so a regression that resolved the construction to the
wrong member of the right module would have kept the test green — it pinned
the file, not the answer.

Assert the exact edge set for the caller instead. Verified against the current
tree with a scratch probe: `builds -> Model@pkg/db.py` is the only edge the
file produces.

* docs(plans): include the #2826 engineering plan in the PR

`.gitignore` keeps `docs/*` local because planning output is normally
throwaway. Force-added here at the reviewer's request so the plan travels with
the work it drove: it records the evidence chain behind the fix, the two places
the plan turned out to be wrong, and the follow-ups deliberately left out of
scope.

* refactor(resolution): make the namespace shadow guard shared (#2826)

`isNamespaceNameShadowed` lived module-private in `compound-receiver.ts` with a
single caller. The namespace map it guards has three consumers, and the next
commit adds the guard to a second one, so it moves to `scope/walkers.ts`
alongside the other scope-chain primitives rather than being duplicated.

Behaviour is unchanged — this is a move plus documentation. Two notes were
added because both are easy to get wrong later:

- Fails closed on a missing scope or a parent cycle. For every caller,
  suppressing costs a missing edge while trusting a corrupt scope chain costs a
  wrong one, so the bias is deliberate.
- It reads `scope.bindings` DIRECTLY rather than through `lookupBindingsAt`,
  which is the opposite of the fix #2745 applied to Rust's `headBoundLocally`.
  There the question was "is this name bound at all?", so missing finalize's
  import channels lost real bindings. Here the question is "does something
  LOCAL shadow the import?", and the import's own finalized binding is exactly
  what must not count — routing this through `lookupBindingsAt` would find every
  namespace import shadowing itself and suppress the lot. Verified against a
  target module carrying a self-named def, which still resolves.

* fix(python): close the three remaining namespace-receiver gaps (#2826)

Three defects the first fix left behind. All three were confirmed by probe
before being touched, and a fourth suspected gap was disproved the same way.

## 1. Case 1 resolved through an import a local had shadowed

`namespaceTargets` is collected per FILE, but Case 1 in `receiver-bound-calls`
consulted it with no lexical guard at all, so

    import pkg.db
    def f(pkg):            # parameter shadows the package
        return pkg.db.session_scope()

emitted an edge to pkg/db.py. That is a WRONG edge, and it predates the dotted
key: the single-segment spelling (`import single` + `def f(single)`) failed
identically. The compound-receiver construction path has applied this guard
since #2770; Case 1 simply never did. Now both use the shared guard.

## 2 + 3. The root key named the leaf module, not the package

These read as two gaps and are one. `import a.b.c` binds ONE name — `a` — but
makes three attribute paths callable, naming three different files:

    a      → a/__init__.py
    a.b    → a/b/__init__.py
    a.b.c  → a/b/c.py

The map keyed only `a`, pointed at the LEAF. So `a.helper()` resolved into
a/b/c.py whenever that module happened to export `helper` — silently preferring
a decoy over the real definition in the package — and `a.b.mid()` resolved to
nothing at all. One wrong edge and one missing edge from a single mis-keying.

Fixing it needs per-language knowledge the shared collector cannot have: which
prefixes are reachable, and which file each names. The `__init__.py` convention
is Python's alone, and the edge shape is ambiguous across languages — Swift's
`import Foo.Bar` produces an identical `localName`/`targetExportedName` pair
that means the opposite thing. So the previous commit's boolean opt-in is
replaced by `ScopeResolver.namespaceReceiverPaths`, which returns every
spelling with the file it names; absent or declining, the shared default
(bound name → own target) is unchanged for every other language.

Prefix files are proposed, not asserted — `moduleFileExists` drops any the
workspace never parsed, so a PEP-420 namespace package contributes no key
rather than one pointing at a missing file.

## Disproved: C# was not a fourth gap

The plan listed C# `using System.Collections.Generic` +
`System.Collections.Generic.List` as the same class of bug. It is not: a probe
shows `My.Deep.Space.Helpers.Work()` already resolves through the FQN namespace
bindings in `walkers.ts`. No change made, and the claim is withdrawn rather
than carried forward as a known gap.

## Testing

Integration: the shadow block asserts the exact surviving edge set (an
absence-only assertion would also pass if the guard over-suppressed and killed
the clean rows); the prefix block asserts all three spellings land on their own
file, with `helper` defined in BOTH package and leaf so a wrong edge is visible
rather than merely possible. Unit: 16 rows on the keying contract, including
that a Swift-shaped edge mints nothing and an alias import keys neither the
path nor the root.

Resolver integration 3024 passed / 1 skipped / 0 failed; scope-resolution unit
1452 passed; tsc clean in both packages.

* fix(python): probe both path separators when resolving a prefix package (#2826)

Workspace file paths are not normalized to POSIX at ingestion — `import-target`
already re-normalizes at five other comparison points, and `moduleScopeByFile`
is keyed by the raw `ParsedFile.filePath`. The prefix probe built only the `/`
spelling, so on Windows it would compare `a/b/__init__.py` against an
`a\b\__init__.py` key, find nothing, and mint no prefix keys at all.

That fails quietly, which is the worst shape for it: `a.b.mid()` simply goes
back to unresolved on one platform, with no drop recorded and every test on
POSIX still green. Probe both spellings and key whichever the workspace
actually holds.

The new row is mutation-tested — reverting to the `/`-only probe turns it red
(1 failed / 10 passed), so it pins the behaviour rather than passing alongside
it.

* fix(python): correct three defects a multi-lane review found in this PR (#2826)

All three were introduced by this PR's own earlier commits, and none was found
by re-reading the diff — each came from a lane attacking an angle the author
had not.

## 1. The shadow guard ran BEFORE the map lookup it gates

Case 1 evaluated `isNamespaceNameShadowed` unconditionally, then consulted
`namespaceTargets`. So every call/read/write site with an explicit receiver, in
every language, paid a scope-chain walk (a Set allocation, three Map lookups and
a linear `ownedDefs` scan per level) ahead of an O(1) hash miss that was going to
decline it anyway.

The proof it was an oversight rather than a decision sits in this same PR: the
sibling guard in `compound-receiver.ts` reads the map first and only guards on a
hit. Two call sites of one shared function, opposite order. Semantics are
identical either way — a miss yields `undefined` regardless — which is exactly
why it survived several readings.

## 2. Prefix packages were anchored on the import spelling, not the resolved leaf

`pythonNamespaceReceiverPaths` built `a/__init__.py` from the dotted path joined
at the workspace root, never consulting the file the import actually resolved
to. But `resolvePythonImportTarget` resolves off-root in two of its three tiers,
so `import utils.db` can land on `libs/common/utils/db.py`. That produced a
wrong edge where a same-named `utils/` package exists at the root, and produced
NOTHING in a `src/` layout — the prefix feature was inert for the most common
Python project shape, silently.

Now the prefix directories are derived by walking back from the resolved leaf,
which is exact for root, `src/` and off-root layouts alike. It also inherits the
leaf's own separator, which subsumes the previous dual-separator probe: that
probe was dead code anyway, because `filesystem-walker.ts` normalizes `\` to `/`
before a path ever becomes a `ParsedFile.filePath`. Its test row is removed
rather than left asserting an unreachable state.

## 3. Keying the root at `__init__.py` INSTEAD of the leaf lost re-exports

`findExportedDef` accepts only a binding whose `origin === 'local'`. The
canonical Python package re-exports from its submodules — `from .b.c import
helper` in `__init__.py` — which is an IMPORT binding, so it is rejected. Keying
the prefix solely at the package therefore turned `a.helper()` from a correct
edge into no edge at all for the most common package shape.

Every fixture in this PR defined its members locally in `__init__.py`, which is
precisely the one layout where that mistake is invisible.

The prefix now keys the package FIRST and the leaf behind it. A real definition
in `__init__.py` still wins over a same-named decoy deeper in the package, and a
name merely re-exported there still resolves through the leaf. Ordering is the
contract, so the unit rows assert the exact arrays rather than membership.

## Testing

New rows: off-root layout with a decoy `utils/` at the root, and a `src/` layout.
Both mutation-tested — reverting to the spelling-anchored build turns them red.
The re-export case was verified end-to-end with a scratch fixture whose
`__init__.py` only re-exports (`uses -> helper@a/b/c.py`).

Resolver integration 3131 passed / 1 skipped / 0 failed — unchanged from before
these fixes, so they regress nothing. Scope-resolution unit 1459 passed.
tsc clean in both packages.

* fix(resolution): stop the namespace shadow guard AT the module scope (#2826)

CI caught a regression this PR introduced: `cjs-exports-assignment.test.ts`
lost both of its cross-file rows —

    cross-file require() member call resolves
      expected [] to deeply equal [ 'handle' ]
    an `exports` parameter does not hijack the module (UMD factory)
      expected [] to deeply equal [ 'publicApi' ]

— i.e. `const svc = require('./svc'); svc.handle()` stopped resolving in
JavaScript.

Cause: in CommonJS the namespace import IS a variable declaration. One
statement produces both the ImportEdge and a module-scope `const` binding, so
the guard, by inspecting the module scope, found the import's own name there and
read it as a shadow of itself — suppressing exactly the receivers it exists to
enable.

The guard's own contract sentence already said the right thing: "a declaration
BETWEEN the call site and its module scope". The module scope is the floor of
that walk, not a rung on it. It now returns at Module without inspecting it.

Nothing is lost on the suppression side: a genuine shadow is a parameter, a
local, or a nested declaration, and all of those live in scopes strictly inside
the module. The Python rows that pin suppression (`def f(pkg): pkg.db.f()` and
its single-segment `import single` twin) still pass, because a parameter is an
inner scope.

Worth recording for the next reader: two independent review lanes examined this
exact scenario and both REFUTED it, reasoning that `require()` yields an
ImportEdge in `scope.imports` rather than a local binding. That is true for
Python's `import x` and false for CommonJS, where one statement is both. My own
probe used a Python fixture and so could not surface it either. Agreement
between reviewers was not evidence; the test corpus was.

Verified: cjs-exports-assignment 36/36, the #2826 integration rows 7/7,
scope-resolution unit 126/126.

fix(go): model Go method sets exactly so interface satisfaction is decidable (#2813) (#2829)
* test(go): pin calls through an interface-typed struct field (#2813)

A call through an interface-typed struct field never reaches the
implementation: the CALLS edge stops at the interface DECLARATION, so
`impact()` on the implementing method reports 0 callers. This commit adds
the executable statement of that defect; the fixes follow.

Two stacked defects produce it, and either alone is enough to reproduce —
which is why no existing fixture could observe it:

  D1  `buildDetectionIndexes` skips every POINTER-receiver method, so a
      struct whose methods are all `func (r *T)` has an empty method set,
      structurally satisfies nothing, and gets no IMPLEMENTS edge. Go's
      rule is that the method set of *T includes pointer-receiver methods,
      and idiomatic Go stores *T in an interface-typed field.
  D2  Case 0 (compound receiver) emits its primary edge and short-circuits
      without the interface-dispatch fan-out Case 4 performs. A struct
      field receiver `s.orderRepo` contains a dot and so always takes
      Case 0; a local or parameter receiver is a bare name and reaches
      Case 4.

Every implementor in both pre-existing structural-dispatch fixtures uses a
VALUE receiver, and the one pointer-receiver type is pinned as a negative
(`not.toContain('PointerOnlyThing -> PointerOnly')`), so the corpus could
not see D1 by construction. The new fixture is pointer-receiver
throughout, cross-package, and carries concrete-field controls in the same
structs.

Failing-first, verified against this tree: 7 of the 11 new assertions fail
and 4 pass. The 4 that pass are exactly the controls that must not
regress — the primary edge to the interface declaration, the concrete-field
call, the absence of fan-out on a concrete field, and the partial-signature
negative — so the suite discriminates rather than merely failing.

Two recorded artifacts move here because the FIXTURE was added, not
because capture output changed:

  - test/fixtures/go-captures-golden/expected-captures.json — regenerated
    additively (32 insertions, 0 deletions).
  - bench/scope-capture/baselines.json — go fingerprint, fixture_count
    102 -> 110.

Both are regenerated in this commit rather than deferred to the end of the
series: the fixture is their only cause, no later commit touches capture
emission, so they cannot re-drift and every commit stays green. The check
that this is corpus growth and not a capture regression is that go was the
only one of 15 language fingerprints to move on the same run.

* fix(go): count pointer-receiver methods toward structural interface satisfaction (#2813)

D1 of two stacked defects. `buildDetectionIndexes` skipped every method whose
receiver is a pointer, so a struct declaring `func (r *OrderRepo) DeleteItem(...)`
had an EMPTY method set, structurally satisfied nothing, and produced no
IMPLEMENTS edge at all.

Go's method-set rule is per-type, and there are two types involved: the method
set of `T` holds only value-receiver methods, while the method set of `*T` holds
both. #1966 implemented the `T` reading, which is exactly right for `T` — and
leaves `*T` permanently empty. GitNexus models one Struct node per type with no
separate `*T` node, so only one of the two can be represented, and the `T`
reading is the one idiomatic Go almost never uses: methods take pointer
receivers so they can mutate, and `*T` is what gets stored in an interface-typed
field.

The cost was silence rather than caution. With no IMPLEMENTS edge, a call
through an interface-typed field resolved to the interface DECLARATION and
`impact()` on the implementing method returned 0 callers — byte-identical to a
symbol that genuinely has none, which is what made the reporter's blast-radius
check unusable rather than merely incomplete.

This picks the `*T` reading: the graph now answers "which types provide this
interface's behaviour", and no longer proves `var x I = T{}` invalid. The trade
is deliberate and was checked against every consumer of IMPLEMENTS before being
made — MRO/METHOD_IMPLEMENTS derivation, community clustering, the
receiver-dispatch fan-out index, and the epistemic heritage probe. None performs
value-assignability checking.

Two negative pins encoded the #1966 decision and are REVERSED here rather than
deleted, each keeping a comment that explains why the polarity moved:
  - go.test.ts: `PointerOnlyThing -> PointerOnly` now expected to be emitted.
  - go-hooks.test.ts: the pointer-receiver-only unit case now expects the
    implementor instead of `undefined`.

`goReceiverKind` is still stamped in method-owners.ts — it is the hook a future
value/pointer-aware model would read — but is deliberately no longer a filter.
Its now-dead local predicate and type alias are removed so the file no longer
carries a helper asserting the reverted rule.

Measured on the #2813 fixture, this commit alone: the two IMPLEMENTS assertions
flip to passing (6 pass, up from 4) while the five interface-dispatch fan-out
assertions still fail — those are D2, fixed in the next commit. Keeping the two
commits separate is what makes that attribution visible.

Go unit suite: 91 passed.

* fix(resolution): fan out interface dispatch from a compound receiver (#2813)

D2 of two stacked defects, and the one that closes the issue. Case 0
(compound receiver) emitted its primary edge and short-circuited without the
interface-dispatch fan-out that Case 4 performs, so a call whose receiver is a
struct FIELD stopped at the interface's method DECLARATION and never reached
any implementation.

The gap was a property of receiver SYNTAX rather than of types. Case 0 is
selected by `receiverName.includes('.')`, so a field receiver (`s.orderRepo`)
always lands there, while the very same interface reached through a local or a
parameter is a bare name and falls through to Case 4 — which fans out
correctly. Field-held interfaces, i.e. dependency injection, were the half that
silently lost every implementation edge; the pre-existing fixtures exercise the
local and parameter forms only, which is why the suite was green.

The fix is the call Case 4 already makes, placed after Case 0's primary
`tryEmitEdge` and before its `handledSites.add`. It stays language-agnostic
(AGENTS.md section 42): `emitInterfaceDispatchFor` self-gates on
`ownerDef.type !== 'Interface'`, so a receiver that folds to a Struct emits
nothing extra and no language check is needed. Confidence is Case 0's own 0.85
literal, not Case 4's site.kind-dependent value — Case 0 has no read/write arm
to mirror.

The case ladder itself is untouched: invariant I4 in contract/scope-resolver.ts
makes the ordering a contract, so the fan-out is added INSIDE Case 0 rather
than by reordering or merging cases.

Also flips a second, previously unnoticed encoding of the #1966 value-only
reading that the full sweep surfaced: the exact-set assertion at
go.test.ts:361 enumerates every structural IMPLEMENTS edge, and D1 correctly
adds `PointerOnlyThing -> PointerOnly` to it. It is D1 fallout rather than D2's,
but D1 had already landed; recording it here with its reason beats amending a
commit whose separate measurability is the point.

Measured:
  - #2813 suite: 11 of 11 pass (was 7 failing after D1 alone, which fixed only
    the two IMPLEMENTS rows).
  - go.test.ts: 160 passed.
  - Full cross-language sweep, test/integration/resolvers: 3027 passed,
    1 skipped, across 52 files. The single failure in that run was the
    exact-set assertion above, fixed here; no other language regressed.

`detect_changes` rates this HIGH (6 affected flows, all EmitReceiverBoundCalls
at step 1) — inherent to editing a hub symbol in the resolution pipeline. The
sweep above is the empirical answer to that label.

An existing index must be re-analyzed to show the new edges; this changes what
the resolver produces, not how it is stored, so no SCHEMA_BUMP applies.

* test(go): pin the heritage edges that make impact() hedge an interface-bound count (#2813)

The epistemic half of the issue, resolved by MEASUREMENT rather than by new
code, and pinned at its mechanism.

The reporter's disqualifying complaint was that `impact()` reported
`impactedCount 0, epistemic "exact", risk LOW` for a method reachable only
through an interface-typed field — byte-identical to what it reports for a
symbol that genuinely has no callers. A zero therefore could not be used
defensively, which was the entire use case.

That verdict comes from `computeEpistemicBoundary`, which has two producers and
neither fired: the call sites were not DROPPED (they resolved, just to the
interface declaration, so the #2744 receiver-typing producer saw nothing), and
its heritage probe walks IMPLEMENTS/METHOD_IMPLEMENTS edges out of the queried
symbol — of which there were none, because the pointer-receiver exclusion (D1)
meant no such edge was ever emitted.

Restoring those edges fixes the epistemics as a side effect, so the planned
conditional change to local-backend.ts is NOT needed. Measured on this fixture
against the fixed tree:

  impact(OrderRepo.DeleteItem, upstream)
    before: impactedCount 0,  epistemic "exact"
    after:  impactedCount 3,  epistemic "lower-bound", with an interface
            boundary note; the three callers are OrderHandlers.Delete,
            PickService.StartSession and WaveService.Release — all correct.

  impact(CartRepo.Get, upstream)  [concrete receiver, no interface]
    after:  impactedCount 1,  epistemic "exact"

The second row is the one that matters for trust: the hedge discriminates
instead of firing on everything, so "exact" still means exact.

This test asserts the METHOD_IMPLEMENTS edges the probe walks. Pinning the
mechanism keeps the resolver suite from reaching into the MCP layer while still
failing loudly if the edges regress; the impact() numbers above are recorded in
the commit message and PR body rather than re-asserted here.

#2813 suite: 12 passed.

* fix(go): model Go method sets exactly so interface satisfaction is decidable (#2813)

Replaces the approximate structural-interface model with the rules the Go spec
actually defines, so the graph answers what the compiler answers instead of a
useful-but-wrong summary of it. Three answers were provably wrong before; all
three are now exact and covered.

Method sets (go.dev/ref/spec#Method_sets):
  MS(T)  = methods declared with receiver T
  MS(*T) = methods declared with receiver *T OR T

Promotion (#Struct_types):
  S embeds T  -> MS(S) and MS(*S) get promoted methods with receiver T;
                 MS(*S) ALSO gets those with receiver *T
  S embeds *T -> MS(S) AND MS(*S) both get receiver T or *T

Identifier identity (#Uniqueness_of_identifiers): "Two identifiers are different
if they are spelled differently, OR IF THEY APPEAR IN DIFFERENT PACKAGES AND ARE
NOT EXPORTED."

  func (b *Base) Ping()      // pointer receiver
  type ByValue struct{ Base }
  type ByPointer struct{ *Base }

  type            before          exact answer
  Base            IMPLEMENTS      only *Base implements
  ByValue         IMPLEMENTS      only *ByValue implements
  ByPointer       IMPLEMENTS      the VALUE type implements

All three were the same edge. Two of the three were wrong, and nothing in the
graph could tell them apart.

Worse, in a different direction:

  package sealed;  type Sealed interface { seal() }
  package foreign; func (t *T) seal() {}

`foreign.T` cannot implement `sealed.Sealed` in Go — `seal` is unexported, so the
two identifiers are DIFFERENT. Matching on the bare name emitted a FALSE
IMPLEMENTS edge, and the interface-dispatch fan-out then turned it into an
impossible CALLS edge. That is the entire basis of the sealed-interface idiom.

- `methodSetKey` qualifies UNEXPORTED method names with their declaring package,
  leaving exported names unqualified (which is what makes cross-package
  satisfaction work at all). Exactness, not a heuristic: the sealed case now
  emits no edge, while the legitimate same-package implementor is retained.
- `collectStructMethodEntries` builds MS(T) and MS(*T) together and applies the
  promotion table above. The embed FORM is load-bearing, so it is now captured:
  `@reference.embedded-pointer` records `*T` versus `T`, which the parser
  previously discarded (the `*` is an unnamed token).
- Detection returns `{ structDefId, receiverForm }`. `receiverForm: 'pointer'`
  means the value type does NOT implement and only `*T` does — the fact
  `var x I = T{}` turns on.
- The form rides in the edge `reason` (`-structural-implements-pointer`).
  Relationships carry no arbitrary properties, so a new field would change the
  relation DDL, move SCHEMA_FINGERPRINT and force a rebuild for a fact a string
  already expresses. Value-form implementors keep the ORIGINAL unsuffixed
  reason, so a consumer matching the old string now sees exactly the assignable
  set — which is what that string always claimed to mean.

- `emitInterfaceDispatchFor` walks the SUBTYPE CLOSURE (IMPLEMENTS + EXTENDS) and
  skips bodiless declarations, instead of stopping at depth 1. Two reproduced
  Java shapes emitted an edge to a second abstract declaration while the only
  class with a body got nothing: a sub-interface that re-declares the method, and
  an abstract base between interface and implementation. Both now reach the
  implementation and neither emits the declaration edge.
- The fan-out is bounded by `MAX_INTERFACE_DISPATCH_FANOUT` (32,
  `GITNEXUS_MAX_INTERFACE_DISPATCH_FANOUT`) and reports what it dropped, mirroring
  `MAX_PROPERTY_DISPATCH_FANOUT`. A bare cap would silently discard valid dispatch
  targets, which is the same false-safe silence this issue is about.
- Corrects a rationale comment that was factually wrong about the code 70 lines
  above it (Case 0 DOES branch on `site.kind`, at :713-716; what it lacks is a
  read/write branch in its reason/confidence computation).
- Updates both copies of the case-ladder contract, which still described the
  fan-out as Case-4-exclusive.

The embed-pointer marker is PARSE-TIME capture emission, so a warm cache would
replay the pre-marker capture set and the distinction would never appear —
silently, the v27/v30 failure mode. 43 and not 40 because origin/main allocated
40, 41 and 42 while this branch was in review, which is exactly the window this
file's history records both prior EXACT clashes landing in. Pin moved with it.
RE-CHECK AGAINST origin/main IMMEDIATELY BEFORE MERGE.

- Go unit: 93 passed, including new rows pinning that `populateGoOwners` stamps
  `goReceiverKind` (previously the field had no reader and could rot silently)
  and that a pointer-receiver-only type implements in POINTER form only.
- Cross-language sweep, test/integration/resolvers: 3034 passed, 1 skipped,
  52 files, zero regressions.
- scope-capture bench: PASS (15 languages). Go is the ONLY fingerprint that
  moved, which is the check that this is a Go capture change and not a
  cross-language regression; rebaselined with rationale.
- Also closes review gaps in this PR's own tests: the concrete-field control was
  vacuous with respect to the type gate (repointed at a struct that IS an
  implementor), the two-service-file row could not distinguish the two files it
  is named for (both ends now file-qualified), plus new rows for signature
  mismatch, emitted confidence, and an exact N-by-M fan-out bound.

An existing index must be re-analyzed; the schema bump forces it.

fix: type an inference-typed class field so it can act as a call receiver (#2807) (#2810)
* test(helpers): add the shared temp-repo lifecycle helper

`createTempDirPool` gives a suite one owner for its temp fixture repos —
create on demand, remove them all in one `afterAll` — instead of a hand-rolled
mkdtemp/rmSync pair per file. The PDG receiver pin added in the next commit
uses it.

Cherry-picked verbatim from ec36c6dda on the #2802 branch, where it was
extracted to collapse five hand-rolled cleanups. Identical content, so if both
branches land the add resolves as a duplicate rather than a divergence.

* fix(typescript): type a class field from its initializer so it can be a receiver

A field whose type had to be inferred from its initializer produced no CALLS
edge at all — not a truncated chain, nothing. `this.p.inner().compute(x)` lost
`Outer.inner` too, an ordinary named-receiver call, because `typeOfMemberOnClass`
found no `typeBindings` entry for `p` and `foldReceiverChain` declines at its
first untypeable step rather than folding on a guessed owner.

The initializer was never invisible: `new Outer()` emitted its own constructor
edge exactly as the annotated twin does. What was missing was the step turning
that initializer into a TYPE BINDING, i.e. capture patterns for the two shapes
the query never covered:

  private p = new Outer();                       // public_field_definition value:
  private p; constructor() { this.p = new … }    // this.<field> = new …

Both are `@type-binding.constructor`, so `annotation` still outranks them in
`typeBindingStrength` and an annotated field keeps resolving through its
annotation. The assignment form carries a narrow `@type-binding.this-field`
marker on its `(this)` node — anchorCaptureFor takes the broadest range, so the
statement stays the anchor — which `tsBindingScopeFor` reads to hoist the
binding onto the Class scope, the only place `typeOfMemberOnClass` looks. The
marker must stay specific to that pattern: hoisting every constructor-inferred
binding would move method-local `const o = new Outer()` out of its own scope.

Kotlin and Swift needed no such pattern for the initializer form because one
grammar node (property_declaration) covers both a local and a stored property;
TypeScript splits them, and only the local half was ever covered.

Both self-diffing pins flip and gain rows: a method-assigned field, and a
deliberately mistyped `private p: Mismatch = new Outer()` that asserts the
source-strength tie-break executably. That row also pins a pre-existing
artifact — `Inner.compute` still resolves through the hoisted module-level
return-type binding — verified byte-identical on the pre-fix tree.

* fix(javascript): type a class field from its initializer so it can be a receiver

JavaScript has no field annotations at all, so a class field's type can only
ever come from its initializer — which made this the strictly worse half of
#2807: `class C { p = new Outer(); }` gave `this.p` no type, and
`this.p.inner()` emitted nothing.

`synthesizeConstructorFieldBindings` in captures.ts already covered the sibling
shape, `this.p = new Outer()`, which is why THAT row resolved — but it only
walks `constructor` bodies, so a field initialized at its declaration matched
no pattern anywhere.

Adds the `field_definition` + `value: (new_expression)` patterns (the JS grammar
names the field `property:`, not `name:`), anchored so the binding lands in the
class body scope where `typeOfMemberOnClass` reads it. No hook change needed:
`jsBindingScopeFor` already delegates to `tsBindingScopeFor`, so it inherits the
`@type-binding.this-field` branch too.

Measured: `InferredField.run` now emits `Outer.inner`, exact parity with both
the local-const control and the constructor-assigned row. The second chain link
(`Inner.compute`) stays absent in ALL THREE rows — that is JavaScript's separate
return-type-inference gap, not this one.

* fix(python): infer an instance field's type from the constructor it calls

`self.outer = Outer()` in `__init__` bound nothing, so `self.outer.inner()`
had no receiver type and the fold declined the whole chain — the Python half
of #2807. An annotated field (`self.outer: Outer = ...`) or one assigned from
an annotated parameter already worked.

`synthesizeConstructorFieldTypeBindings` deliberately refused to infer "from
arbitrary unannotated RHS expressions ... not a name-only guess". A CALL is not
that: Python has no `new`, so a call to a plain (or dotted) name is the only
syntactic construction form there is, and it is the same positive evidence
every other language reads from `= new X()`. A bare name, subscript, await or
comprehension is still refused.

Adds it as a THIRD and weakest tier. The existing explicit/parameter boolean
becomes a rank, so precedence is now explicit annotation > parameter annotation
> construction, and a later same-tier assignment still wins (the last write in
`__init__` is the live one). `interpretPythonTypeBinding` maps the new marker to
`constructor-inferred` (strength 1) — checked before the parameter branch, which
would otherwise have read the absent parameter marker as `annotation` and
promoted a guess to the strongest tier.

The Class-scope hoist needed no change: `@type-binding.instance-field` already
carries it in `pythonBindingScopeFor`.

Measured: `AssignedField.run` now emits `Outer.inner`, exact parity with the
annotated-field and local-const rows.

* fix(ruby): infer an instance variable's type from the constructor it calls

`@service = UserService.new` in `initialize` bound nothing, so `@service.inner`
had no receiver type and the fold declined the whole chain — the Ruby half of
#2807. An instance variable is the ONLY way a Ruby object gets a field, and
Ruby has no annotations, so this was the single shape that could have worked
and did not: the existing constructor-inferred patterns bind a local
(`x = Foo.new`) and a constant (`SERVICE = Foo.new`), never an ivar.

Adds the plain and `Foo::Bar` qualified ivar forms. `@type-binding.name` is
captured on the `instance_variable` node so the bound name keeps its `@` sigil
and matches the receiver text at the call site verbatim — the resolver compares
spellings, and `service` would never have matched `@service`.

`rubyBindingScopeFor` gains a Class hoist gated on a narrow
`@type-binding.ivar-field` marker riding the same node: an ivar declares a field
of the enclosing class, so the binding must live on the Class scope or no other
method can see it. Gated on the dedicated marker, never on
`@type-binding.constructor` at large, which also fires for `x = Foo.new` locals
that must stay in their own method.

Measured: `AssignedField.run` now emits BOTH chain links, exact parity with the
local-const control.

* test(resolvers): pin inference-typed field receivers across eight languages

#2807 was filed against TypeScript, but the defect class is cross-language:
"can a field whose type is inferred act as a call receiver". This measures all
eight languages where the shape exists at all, in one table.

The metric is parity with EACH LANGUAGE'S OWN CONTROL ROW, not "both chain
links present". JavaScript, Python, Dart and PHP lose the second link
(`Inner.compute`) even for a plain local, because nothing annotates `inner()`'s
return type — a separate return-type-inference gap. Scoring against "both
links" would have accused those four of a bug they do not have; scoring against
their own control isolates the field-typing question cleanly.

Recorded state: TypeScript, JavaScript, Python and Ruby now match their
controls. Kotlin and PHP already did before #2807 and are pinned so the shared
fold cannot regress them unnoticed — the languages that got receiver typing for
free are precisely the ones nobody re-checks.

Two rows stay pinned BROKEN, at their exact current value:

  Dart  — real and narrow: the annotated control resolves, the inferred one
          does not. Its bindings are synthesized in dart/captures.ts rather
          than by a query, so the fix is its own change.
  Swift — blocked by a different defect found while measuring: with several
          classes each defining `run`, every `run`'s edges are attributed to
          the FIRST-declared one, which collects duplicates while its siblings
          — including the ANNOTATED control — collect none. Receiver typing
          cannot be measured there until that is fixed, and "fixing" it against
          this observable would be fitting to a broken measurement.

Both gap rows carry a `callerExists` probe in the same assertion object, so an
empty list can never read as "resolved fine, wrong node id", plus a whole-matrix
guard that every language keeps a resolving control — that is what makes a gap
row mean "broken" instead of "fixture never worked".

Targets are deduplicated before comparison: Swift emits one edge more than once
per call site, and edge multiplicity is a different question from whether the
receiver typed at all.

* fix(python): a method call on the receiver is not a construction

Review finding on f4e1ead0d. `constructorCallTypeName` accepted ANY call with
an identifier or attribute callee, so `self.p = self.build()` bound `p` to the
non-type `"self.build"` — and because that shares the weakest tier with a real
construction, a later such assignment DISPLACED an earlier `self.p = Outer()`
and left the field untyped again.

Measured before the fix: `self.p = Outer()` followed by `self.p = self.rebuild()`
emitted no CALLS edge at all from a method chaining off `self.p`, and
`self.q = self.make()` bound a type name that resolves to nothing. After:
the real construction survives the reassignment, and a pure method call binds
nothing rather than something wrong.

Rejects a callee rooted at the receiver name. `models.Outer()` still binds —
only `self`-rooted callees are refused, which is exactly the method-call shape.

The matrix gains a `reassigned-from-method-call` row that fails without this
rejection; that discrimination is the only reason the row exists.

* fix(swift): resolve a method def to its own node when the labels disagree

Two classes in one Swift file each declaring `func run` collapsed onto one
node: every call in BOTH bodies was attributed to whichever `run` registered
first, which collected duplicate edges while its twin collected none. Renaming
one method fixed it; moving it to another file fixed it; so the collision was
name-keyed and per-file, not positional.

Root cause is a LABEL split, not a name. Swift's structure phase emits a type's
methods as `Function` nodes, while the scope extractor derives `Method` from the
`@declaration.method` anchor. Every key in `resolveDefGraphId` — qualified,
parameter-types, arity, shape — is label-scoped, so such a pair misses all of
them and lands on the bottom fallback, `simpleKey(filePath, name)`, which is
deliberately label-agnostic and first-write-wins.

Fixed at both ends:

  - Swift qualifies a method def as `<Type>.<method>`, matching the qualifier
    the structure phase already encoded in the node id. `class`, `struct` and
    `extension` all parse to `class_declaration`, so one ancestor walk covers
    them; a generic `class Box<T>` and an `extension Foo` wrapping a `user_type`
    both reduce to the bare owner name.
  - The bridge retries the qualified keys under the sibling callable label.
    Gated on the name containing a dot: `A.run` names one construct whatever the
    label, while a bare `run` is exactly the top-level-vs-method aliasing the
    label was added to prevent, so the original guarantee is untouched.

This also unmasked Swift's #2807 row. `let p = Outer()` had always bound
correctly — its edges were being credited to the wrong caller, so the
inference-typed receiver looked broken when it was not. `InferredField.run` now
emits `Outer.inner`, matching its control.

Verified on the full resolver + CFG suite: 3165 passed, 0 failed, against a
3164-passing baseline.

* fix(dart): declare inference-typed class fields so they can be receivers

`var b = Outer();` produced no `@declaration.property` capture at all — no
Property node, and nothing for the capture layer to hang a type binding on — so
`b.inner()` could not type its receiver while the annotated twin
`Outer b = Outer();` resolved fine (#2807).

The gap was in the query, one layer below where the binding is emitted: both
class-field patterns require a leading `(type_identifier)` or `(nullable_type)`,
i.e. a WRITTEN type. Dart puts the keyword there instead for an inferred field,
and spells it two ways — `inferred_type` for `var`, `final_builtin` for `final`
and `late final`. Covering only `var` would have left the more idiomatic Dart
style broken, so both are matched.

With the field declared, the capture layer types it from the constructor its
initializer calls, as `constructor-inferred` — the weakest source, and the
annotated branch returns before it, so an annotated field is untouched. Only a
direct construction is accepted (a bare identifier followed by a `selector`
carrying an `argument_part`, the same shape `findDirectCallValue` accepts for
locals); a literal, member call or await is left alone rather than guessed at.

Note this is the LOCAL/field split that made the gap invisible: `emitVarTypeBinding`
already handled `initialized_variable_definition`, but a class field is
`declaration(<keyword>, initialized_identifier_list(initialized_identifier))`.

`InferredField.run` now emits `Outer.inner`, matching its control. Dart's
`var r; C() { r = Outer(); }` shape stays pinned as a known gap: Dart writes the
field with no receiver prefix, so binding it means treating assignment to a bare
identifier as a field write, indistinguishable from a constructor-local.

* test(resolvers): record Swift and Dart reaching parity in the matrix

Both languages' inference-typed field rows move from KNOWN GAP to resolving,
which is the self-diffing signal this file was built to produce: closing either
gap failed it with the newly resolved ids in the diff.

The header table and prose are corrected together with the rows, as the file's
own instructions require — including WHY Swift moved. Its `let p = Outer()`
binding had always been correct; a separate label-split defect attributed the
second same-named method's calls to the first, which masked this row entirely.
Recording that is the point: a future reader comparing the table against the
code needs to know the row was never a receiver-typing failure.

One row stays pinned: Dart's `var r; C() { r = Outer(); }`. Dart writes fields
without a receiver prefix, so binding it means treating assignment to a bare
identifier as a field write — indistinguishable from a constructor-local until
the field set is known. Idiomatic Dart writes `final r = Outer();`, which the
inferred-field row now covers.

Every language keeps its resolving control row, so the remaining gap still means
"broken" rather than "fixture never worked".

* fix(dart): type a field from a constructor assigned to it

`var r; C() { r = Outer(); }` bound nothing, so `r.inner()` had no receiver
type — the last inference-typed field shape still failing after the initializer
form was fixed (#2807).

Dart is the one language here that writes a field with NO receiver prefix, so
`r = Outer()` inside a constructor is syntactically identical to assigning a
constructor-local. That ambiguity is why this was initially left pinned — but
the field set IS knowable: the class body declares `var r`, which the
initializer fix already turned into a property declaration. So a bare name binds
exactly when Dart itself resolves it to the field: the enclosing class declares
it AND the enclosing body declares no local of that name. A `this.`-prefixed
write is unambiguous and needs neither test.

The shadowing case is asserted, not assumed: with a body-local `var s = Outer()`
in scope, the field stays unbound while the local still resolves on its own.

Binds `constructor-inferred` (weakest source, so an annotation still wins), and
only for a direct construction — an identifier followed by a `selector` carrying
an `argument_part`, the same shape accepted for locals. The narrow
`@type-binding.dart-field` marker drives the Class-scope hoist in
`dartBindingScopeFor`; gating on it rather than on `@type-binding.constructor`
at large is what keeps genuine locals in their own scope.

All three shapes now match their control: bare `r = Outer()`, `this.s = …`, and
a non-constructor `setUp()` assignment.

* fix(swift): type an optional field and read through its force-unwrap

Swift cannot declare a stored property with neither a type nor an initializer,
so its "declare now, assign in init" idiom is an OPTIONAL field read back
through a force-unwrap. That shape resolved nothing, and it was broken in two
independent places — each alone leaves it broken:

  1. `var a: Outer?` parses as `type_annotation(optional_type(user_type(…)))`,
     but the property-annotation pattern required the `user_type` to be a DIRECT
     child, so an optional field was never typed at all. The pattern added here
     captures the INNER `type_identifier`, so the binding is `Outer` without
     relying on `stripOptional` reducing an `Outer?` spelling.
  2. `self.a!` is a `postfix_expression`, which the receiver walk did not peel,
     so even a typed field could not be read through the unwrap.

For (2), `postfix_expression` is NOT added to `TRANSPARENT_RECEIVER_WRAPPERS`
outright: unlike TypeScript's `non_null_expression` — which is only ever `!` —
Swift's node also carries user-defined postfix operators, which can return
anything. Peeling those would type the receiver as the operand and mint a
confidently WRONG owner, the failure mode compound-receiver.ts calls strictly
worse than no edge. So the peel is operator-gated: transparent only when the
node's text ends in `!`, which is provably type-preserving.

Verified: force-unwrap `self.a!.inner()`, optional chain `self.b?.inner()`, and
the plain annotated field all resolve; previously only the plain one did.

The gate keeps this off every other language — `postfix_expression` is not a
node type the other grammars produce here — and the full resolver + CFG suite is
green at 3166 passed / 0 failed, against a 3165 baseline.

* test(resolvers): close the last two matrix gaps

Dart's `assigned-field` and Swift's new `optional-assigned-field` rows now
resolve, leaving no known-gap row in the matrix: every language reaches parity
with its own control on both the initializer and the assigned shape it can
express.

The Swift row is new because the shape it covers did not exist in the fixture:
Swift cannot declare a stored property with neither type nor initializer, so its
assigned form is an optional field written in `init` and read through a
force-unwrap — a shape that needed both an optional-annotation pattern and an
operator-gated receiver peel, which is why the row's comment names both.

The header records how the two hard cases were fixed, including the Dart
shadowing rule the fix depends on: a bare `r = Outer()` binds only when the class
declares that field and the body declares no local of the same name.

* chore(bench): rebaseline the receiver-resolution and scope-capture gates

Both gates are exact-match, so the improvements in this branch fail CI until the
baselines move and the movement is explained. Caught by running the CI gates
locally — the resolver and CFG suites are green throughout and never see these.

receiver-resolution — three shapes moved to RESOLVES, no drop-count changed:

  ruby.fieldReceiverCall     INVISIBLE-GAP -> RESOLVES  (`@ivar = Foo.new`)
  swift.decoratedFieldType   INVISIBLE-GAP -> RESOLVES  (`var a: Outer?`)
  kotlin.nonNullAssert       VISIBLE-GAP   -> RESOLVES  (`x!!` receiver)

scope-capture — swift and typescript fingerprints, both ADD captures and remove
none; the per-language `_rebaselined_inferred_field_receiver_2807` notes carry
the detail and the prior digests. The other 13 languages are unchanged, which is
the check that this is the intended emission and not a capture regression.

CORRECTION to d5d878033's message, which claimed the operator-gated
`postfix_expression` peel "keeps this off every other language — postfix_expression
is not a node type the other grammars produce here". That is wrong: Kotlin's
grammar produces it too, and `kotlin.nonNullAssert` moving to RESOLVES is the
proof. The peel is still correct there — Kotlin `!!` is a non-null assertion with
exactly the type-preserving semantics the `!` gate tests for — but it is a
BEHAVIOUR CHANGE IN KOTLIN, not Swift-only as stated. The gate is what surfaced
it; the claim should have been verified rather than asserted.

* fix(cache): bump SCHEMA_BUMP for the six-language capture change, + review fixes

SCHEMA_BUMP 39 -> 40. THIS IS THE MERGE-BLOCKER of the review: every language
change in this PR is PARSE-TIME capture emission, and `analyze` skips tree-sitter
dispatch for byte-unchanged chunks (GUARDRAILS.md:34), so a warm cache replays
the pre-fix capture set verbatim and the new receiver edges never appear —
silently, no error. Exactly the v27/v30 failure mode this file already documents.
The PR description's claim that "no schema or version constant applies" was
wrong on both counts: a bump IS required, and a plain re-analyze does NOT
surface the captures without it. Re-check against origin/main before merging —
main was also at 39 when 40 was allocated, and this file records eight prior
collisions.

Also from the review:

- dart/simple-hooks.ts hand-rolled a 9-line parent walk byte-identical to the
  shared `walkToScope(innermost, tree, 'Class')` that TypeScript and Ruby call
  in one line in this same PR. Now uses the helper.
- utils/call-analysis.ts: the doc framed the postfix-`!` peel as Swift-only. It
  is not — Kotlin `!!` parses as the same node and is peeled too, which the
  receiver-resolution bench proved (kotlin.nonNullAssert VISIBLE-GAP ->
  RESOLVES). The comment now says so, and names the `!` gate rather than the
  language as the bound.
- test/helpers/temp-dir-pool.ts: its doc claimed four consumers; on THIS branch
  only `pdg-chained-receiver-callees` uses it (the other three convert on
  #2802). Corrected, and the byte-identical-to-#2802 intent recorded.
- inferred-field-receiver-matrix: adds the Dart shadowing assertion the header
  comment already CLAIMED to make but never did. First attempt was vacuous —
  `var s = Outer()` is a declaration, so it never produced the bare
  `assignment_expression` the guard inspects; removing the guard did not fail
  the row. Fixture corrected to `var s; s = Outer();`, and mutation-verified:
  guard present 35 pass, guard removed the row goes red.

* test(cache): move the SCHEMA_BUMP pin to 40

The pin at incremental-parse-cache.test.ts asserts the exact value on purpose —
it exists to catch two branches claiming one number, and it has earned that
eight times. Bumping the constant to 40 without moving the pin turned it red.

Found by the Codex (gpt-5.6-sol) review leg, which flagged it as a
deterministic committed-test failure. The Claude lanes could not have caught it:
they were dispatched before the bump landed.

The comment now records the 39 -> 40 movement and its reason, matching the
existing convention in that block.

* fix(dart): treat every binder as a field shadow, not just local declarations

Review P1, reproduced by two independent reviewers. `emitDartFieldAssignmentBindings`
binds a bare `r = Outer()` to the FIELD when the class declares `r` and the body
declares no local `r` — but the shadow set was built by walking for
`initialized_variable_definition` only. That is one binder form out of many, so a
formal PARAMETER named like a field slipped through:

    void reset(Alpha r) { r = Alpha(); }   // r is the PARAMETER

retyped the FIELD to `Alpha`, fabricating an edge AND destroying the correct
`Beta` binding the constructor had established. The mutation test shows exactly
that: the pre-fix result is not a missing edge but a WRONG one (`Other.inner#0`
instead of `Outer.inner#0`) — the failure mode compound-receiver.ts:519-537 calls
strictly worse than no edge.

The node types were chosen from real grammar output, not assumed. Two facts drove
the design: formal parameters live on the SIBLING `method_signature`, never inside
`function_body`, so no walk of the body could ever have seen them; and
`formal_parameter` carries a `name` field only when typed — untyped, `this.` and
`super.` forms do not. `collectDartBodyShadows` therefore walks the signature AND
the body, collecting formal/closure/local-function/named/optional params,
`this.`/`super.` constructor params, catch bindings, for-in variables, and both
local-declarator forms. A parameter shape whose name cannot be read contributes
nothing — declining to bind is the safe direction.

A 27-case binder sweep passes: 26 shadow shapes bind nothing, the no-binder
control still binds.

Four new matrix rows (param, closure param, catch, loop var) assert a surviving
POSITIVE target rather than an empty list — deliberately, because the pre-fix
value is a different non-empty target, so these rows cannot pass vacuously the way
an empty-assert row can. Mutation-verified: reverting captures.ts turns exactly
those four red and leaves every pre-existing row green.

SCHEMA_BUMP is already at 40 on this branch for the six-language capture change and
has not shipped, so it covers this too; re-check against origin/main before merge.

* fix(ruby): don't bind a class-object @ivar as an instance field

Review P1. The `@ivar = Foo.new` patterns added on this branch hoist to the
enclosing Class scope without asking WHOSE `self` owns the ivar. In Ruby an ivar
written in singleton context belongs to the class object, not to instances, so

    def self.build; @pool = Alpha.new; end
    class << self; def make; @cache = Alpha.new; end; end

bound `@pool`/`@cache` as INSTANCE fields, fabricating edges from instance methods
that read an ivar which is never assigned on an instance.

Three corrections came out of fixing it:

1. The detection premise was wrong. `def self.build` is NOT a `method` node with a
   `self` receiver — it is its own node type, `singleton_method`, and
   `childForFieldName('receiver')` returns NONE on it. Matching on a receiver field
   would have detected nothing, silently. Detection is by node type:
   `singleton_method` / `singleton_class`.

2. A THIRD form exists that the review did not name: a class-body-level
   `class C; @shared = Outer.new;` is the same defect (self is the class object),
   and is likewise new on this branch — before it, `left: (instance_variable)`
   matched nothing at all.

3. Dropping only the `@type-binding.ivar-field` marker is NOT sufficient, and the
   class-body case is what proves it: with the marker gone the binding falls back
   to its innermost scope, which at class-body level ALREADY IS the Class scope, so
   it still lands in the wrong place. The whole match is therefore discarded.

The check lives in `languages/ruby/captures.ts` because `Capture` carries only
`{name, range, text}` — no AST node — so `rubyBindingScopeFor` structurally cannot
ask whose `self` owns the ivar. All Ruby logic stays under `languages/ruby/`.
`method` alone is not a sufficient "instance" signal, since a `def` inside
`class << self` is reached through a `method` node first.

Cost relative to main is zero: a class-object ivar goes back to binding nothing,
exactly as before these patterns existed.

The three new rows are structurally two-sided, not just mutation-checked: each
empty row is paired with a non-empty `*-instance-ivar` row on the SAME fixture
class, so breaking the hoist entirely turns the partner red while an unconditional
hoist turns the empty row red. Mutation-verified in both directions.

* fix(typescript,javascript): bind `this.field = new X()` only inside a class method

Review P0, the most serious finding of the tri-review and reproduced by two
independent reviewers. The `this.<field> = new X()` patterns added on this branch
were CONTEXT-FREE: they matched anywhere in the file, and `tsBindingScopeFor`
hoisted to the nearest enclosing Class without asking whose `this` that was. Since
the binding lands on the same Class scope with the same `constructor-inferred`
source as the field-initializer pattern, and pass4CollectTypeBindings prefers the
later match on `>=`, it OVERWROTE the class's real field type. Reproduced from a
non-arrow callback, an object-literal method, a static method, and module level.

Fixed STRUCTURALLY, in the query: both patterns are now nested under
`class_body -> method_definition -> body: (statement_block) -> (expression_statement)`,
which kills the callback, object-literal and top-level triggers with no runtime
code and mirrors JavaScript's `synthesizeConstructorFieldBindings` discipline.
TypeScript still accepts ANY method, not just `constructor`, so the setter case
this branch deliberately supports keeps working.

`static` needed one emit-side guard: it is an ANONYMOUS token on `method_definition`
with no field name, and tree-sitter patterns cannot negate an anonymous token
(checked against node-types.json), so `isStaticMethodThis` drops it in captures.ts.
`simple-hooks.ts` is comment-only — the unconditional Class hoist is now documented
as safe BECAUSE the marker's producers are bounded, with a note that widening them
means re-establishing that.

Also fixes a `.ts`/`.js` disagreement the narrowing itself created: JavaScript's
synthesis matched `method_definition` ANYWHERE, so an object literal containing a
method named `constructor` still typed the enclosing class's field. Measured on
identical source — JS emitted `p -> Alien`, narrowed TS emitted nothing — and
closed with a `node.parent?.type !== 'class_body'` guard in javascript/captures.ts.
The two languages must not disagree about the same source.

Deliberately NOT matched (a missing binding, never a wrong one — JS declines these
too): an assignment in a nested block, or inside an arrow where `this` genuinely IS
the instance.

Evidence the narrowing removed nothing legitimate: `bench/scope-capture --check`
passes with the TypeScript AND JavaScript fingerprints BYTE-IDENTICAL. The five new
matrix rows use an `Alien` class that also declares `inner()`, so a regression SWAPS
the target rather than emptying the set — they cannot pass vacuously. Mutation
test: reverting the source turns exactly those rows red (`+ "Alien.inner#0"`,
`- "Outer.inner#0"`).

SCHEMA_BUMP stays at 40 — this PR's existing bump covers the capture change being
narrowed, and the buggy variant never shipped outside this branch.

* fix(resolution): consult the sibling callable label in the position key too

Review P1. This branch added a sibling Method<->Function retry to the qualified
keys in `resolveDefGraphId`, but not to the #2699 POSITION key or its fail-closed
guard, which both stayed scoped to `def.type`. Since the premise of the whole fix
is that Swift defs are `Method` while nodes are `Function`, the position lookup
missed and the fail-closed guard could NEVER FIRE for exactly the case the retry
serves — so a function-local `func helper` inside `Host.run` was deterministically
aliased onto the class method `Host.helper`, even with differing arity.

Two earlier reviewers REFUTED this by arguing the guard runs before `lookupTagged`.
That is true and irrelevant: the guard is scoped to `def.type`, so in the
label-split case it is unreachable. Recording it because two independent lanes
agreeing on a refutation is not proof.

`siblingCallableLabel(label)` is now the single definition, consulted by all three
key families:
  - position key: retried under the sibling label, gated on `posHit === undefined`
    so an AMBIGUOUS_POSITION tombstone still falls through to the name keys rather
    than being resolved by relabelling. Deliberately NOT dot-gated — a position key
    is not a name, so the aliasing risk the dot gate exists for does not apply.
  - fail-closed guard: mirrored unconditionally (it only ever returns undefined).
  - qualified retry: dot gate untouched.

Measured before -> after on a Swift fixture: `Host.helper#1 -> sink` (the local
body's call credited to the public 1-arg method) becomes
`Host.run.helper@8:8#2 -> sink`, with the local's own node no longer edgeless.

SCOPE CORRECTION to the P1 report: only the first consequence is a bridge defect.
The second — "`run`'s call to the local resolves to the method" — is NOT reachable
from ids.ts. Both defs carry qualifiedName `Host.helper` and label `Method`, and
the binding hands the target side the class-member def, so the scope walk in
free-call-fallback picks the member. No def->node mapping can change that; it is
pinned as an explicitly labelled KNOWN GAP rather than left implied.

Verification, on shared code so the full bar: resolvers+cfg 3170 passed / 1 skipped
/ 0 failed; `bench/receiver-resolution --check` OK; `bench/scope-capture --check`
PASS (15 languages, Swift fingerprint unchanged) — i.e. the bridge change altered
no capture output. The 3170 reconciles against the 3167 pre-existing at a5bf4c2da
plus exactly 3 new tests; 3167 differs from the older 3166 baseline because
0418b0aac added the matrix's only known-gap row, which emits one extra `it`.

Mutation test: with both arms reverted, 3 of the 5 new cases go red, each arm
pinned independently — the guard case registers no position key, the position case
registers no local-name key.

* refactor: apply cleanup-review findings across the receiver-typing change

Four parallel quality lanes (reuse, simplification, efficiency, altitude) over
`origin/main...HEAD`. Eleven fixes; both exact-match bench gates hold with every
capture fingerprint BYTE-IDENTICAL, so none of this changed what the analyser emits.

Reuse — stop re-rolling helpers that already exist:
- `walkToScope` moved out of the TypeScript provider into a language-neutral
  `utils/scope-tree-walk.ts`. Ruby and Dart had begun importing it FROM
  `languages/typescript/`, which made three unrelated providers depend on the TS
  module for a generic `Scope`/`ScopeTree` walk. Python's hand-rolled copy — the
  one this PR's new `self.x = Outer()` path routes through — is folded in, so all
  six languages now share one traversal.
- Swift stops string-parsing a type name. `swiftEnclosingTypeName` split on `<`
  and `.`; `swiftBaseTypeIdentifier` + `swiftQualifiedBaseTail` do it structurally
  and correctly skip the sibling `type_arguments` node, which the string form only
  guessed at. `findEnclosingTypeDeclaration` replaces the inlined ancestor walk.
- TypeScript uses the canonical `hasKeyword(method, 'static')`. The previous
  `child.type === 'static'` is the exact form `isStaticMember` documents as
  grammar-version-fragile: "`static` can appear as an unnamed token or as a
  keyword node depending on grammar version; check text."
- Both new test suites use `cleanupTempDirSync`, which exists because a pipeline
  test's open handle surfaces as EBUSY/EPERM on Windows and `force` does not
  suppress it. This repo shards Windows CI.

LATENT DEFECT, found by the reuse lane and fixed: `var a = X(), b = Y();` parses
as ONE `declaration` with two declarators, and the query matches it once per
declarator with the SAME node — so the first-descendant search handed every
declarator the FIRST one's initializer. `b` resolved as `X`. Now reads
`nameNode.nextNamedSibling`, which is both correct and free. Pinned by a
`multi-declarator-inferred-field` row ordered so the declarator under test is the
second; reverting the fix turns exactly that row red with the wrong edge.

Efficiency — measured, not asserted:
- Dart's shadow set was built eagerly for EVERY method body and discarded 87-100%
  of the time (a `this.`-prefixed write never reads it). Now lazy and memoised per
  body, gated on `fields.has()`. Semantics are unchanged: the set is body-wide, so
  deferring construction cannot change its contents.
  Worth recording WHY CI could never have caught this: `bench/scope-capture` gates
  the SCALING RATIO, and the work is linear — ratio stays 1.0 against a 1.5 budget
  while a constant-factor regression passes straight through.
- `isTransparentReceiverWrapper` crossed the `node.type` native getter twice on the
  common path. One hoisted read, and — since absent and ungated are distinguishable —
  one `get` replaces `has`+`get`.

Simplification:
- One `Map<string, string | null>` replaces the parallel Set + Map that both
  expressed "this wrapper is transparent", with `null` meaning unconditional.
- `ids.ts` computed `siblingCallableLabel` twice under two names. The three retry
  blocks are deliberately NOT collapsed — they use different key builders and
  materially different gates.
- Python's `interpret.ts` nesting was only a consequence of arm ORDER; swapping the
  arms is unconditionally equivalent (the two differ only when both markers are
  present, and both orders then yield `constructor-inferred`).
- One `isDirectConstruction` predicate replaces the construction-shape test that
  had been written four times in dart/captures.ts.

Deliberately NOT done, each needing a fingerprint rebaseline or new node ids:
unifying the six `@type-binding.*-field` markers into one canonical capture (it
would change Python's anchor semantics, which must be verified not assumed); a
Swift `labelOverride` mirroring Kotlin's four-line fix, which is the real cure for
the Method/Function split the bridge currently compensates for; generalising the
Swift optional-annotation pattern to `(type_annotation (_))` so the existing
strippers handle every wrapper; and merging the TS query with the JS walker, which
also carries a JSDoc branch no query can express.

* test(swift): regenerate the Swift captures golden for the optional-annotation pattern

CI caught what my local runs did not: `swift-captures-golden.test.ts` pins
`emitSwiftScopeCaptures` output across every `swift-*` fixture, and this branch
changes that output. It is a THIRD capture gate, separate from the two
exact-match benches already rebaselined here — `bench/scope-capture` hashes a
different corpus, so its Swift fingerprint moving did not imply this one, and
passing it was not evidence this was clean.

The drift is digest-only: 37 changed lines, 37 in each direction, no capture
entry added or removed. That is the expected shape for
`(type_annotation (optional_type (user_type …)))` making optional properties emit
an annotation binding they previously did not, plus the `@declaration.qualified_name`
now carried on Swift method declarations.

Regenerated with the mechanism the test itself prescribes (`UPDATE_GOLDEN=1`),
not by relaxing the assertion. Verified after: all Swift unit + resolver suites
green (4 files, 124 tests), and `bench/receiver-resolution --check` still exactly
matches its baseline.

* fix: three more wrong-owner defects, found by a second review round

A second tri-review of this PR found THREE new P1 wrong-owner defects — every one
of them in code the FIRST round had already fixed. All three are the same root
shape: an incomplete ENUMERATION of binder or scope forms. That class has now
bitten this branch four times (formal parameters, then these), so two of the
three fixes below deliberately attack the class rather than the instance.

1. DART 3 PATTERN BINDERS (P1, reproduced by two independent lanes).
   `addDartBinderName` enumerated five binder node types, and every Dart 3
   pattern form parses into node types in NONE of them — so a pattern-bound local
   did not count as a shadow and its write retyped the CLASS FIELD:
       class Host {
         var session = Cache();
         void load() { final (session, count) = (Session(), 2); }
         void use() { session.ping(); }   // resolved Session.ping, not Cache.ping
       }
   The grammar hides every rule that would carry a binder (`_pattern_field`,
   `_list_pattern_element`, `_guarded_pattern`, …), inlining children onto the
   enclosing visible pattern node, so binders land as direct `identifier` children
   of just two leaf types. Covers all 10 pattern types that can hold one; the
   eight container types are defence, since the grammar demonstrably inlines
   identifiers onto containers already.
   THE COMPOUNDING PART: a grammar-derived coverage guard reads `nodeTypeInfo` and
   fails if the grammar declares a `*pattern*` type the fixtures do not exercise.
   A grammar bump adding an 11th type now turns the suite red instead of silently
   reopening this bug a third time.

2. RUBY BLOCK-RECEIVER `self` REBINDING (P1 here, both Claude lanes + Codex, which
   rated it P2 — the engines agreed the defect is real and disagreed on severity).
   `isRubyInstanceIvarWrite` enumerated `singleton_method`/`singleton_class` as the
   ways `self` gets rebound. A `def` inside a BLOCK attaches to the block's
   receiver, so `Struct.new(:x) do def warm; @a = Beta.new; end end`,
   `Class.new do … end`, `class_eval`, and `other.instance_eval { @a = … }` all
   published onto the nearest LEXICAL class.
   Deliberately NOT fixed by listing rebinding call names: that set is OPEN —
   `def helper(&blk) = Foo.class_eval(&blk)` rebinds a block it merely receives,
   and nothing in the block's own syntax reveals it. An allow-list of "safe"
   iterators would be the same defect one level down. The rule is structural:
   crossing ANY block boundary makes ownership unprovable, so discard. Complete by
   construction rather than by enumeration.
   ACCEPTED COST, asserted not hidden: `[1].each { @shared = X.new }` in an
   instance method really is the instance's `self`, and this drops it — that block
   is syntactically identical to the `instance_eval` one. It has its own row
   (`plain-block-self-ivar`) so the loss is visible rather than discovered later.

3. STATIC FIELD INITIALIZERS (P1, found by Codex/gpt-5.6-sol, corroborated).
   A `static` field initializer was captured as an ordinary instance binding, and
   since both land on one Class scope at the same `constructor-inferred` strength,
   the later wins the `>=` tie-break — so a static field retyped the instance
   field of the same name (`this.p.hit()` -> `Wrong.hit`). Unguarded in BOTH
   `javascript/query.ts` and `typescript/query.ts`; the existing
   `isStaticMethodThis` only ever covered the `this.x =` assignment form.
   Two things surfaced while fixing it: the TS `annotation` pattern collides
   identically and is PRE-EXISTING, not introduced here; and JS `static
   constructor(){}` had no guard where TS did — the .ts/.js divergence this PR's
   own comment claimed could not happen.
   Dart has no same-name twin (the language forbids it), but a static method's
   receiver-less write named a library-level variable and DISPLACED the
   constructor's binding. Fixed narrowly, with a counterweight row
   (`static-field-declaration-still-types-its-receiver`) that goes red if anyone
   widens the guard into "drop every static binding" — reading a static by bare
   name from an instance method is ordinary Dart and must keep working.
   ACCEPTED COST: `typeBindings` has one map per Class scope with no static/
   instance split, so a static field is dropped rather than recorded separately,
   losing typing on a TS/JS `Host.p.hit()` static receiver chain. Missed edge over
   wrong edge, per compound-receiver.ts:519-537.

Every new row asserts a SURVIVING POSITIVE target, never an empty set: the pre-fix
value in each case is a DIFFERENT non-empty target, so none can pass vacuously —
the trap this branch already fell into once. Mutation-verified per fix: reverting
each turns exactly its own rows red (17 Dart, 6 Ruby blocks, 5 static) with every
pre-existing row green.

Matrix 49 -> 80 tests. Siblings 510 passed. tsc clean. scope-capture PASS (15
languages, all ratios within gate).

* fix(dart): mask a shadowed field on the READ side, not just the write side

The review critic refused to pass this PR while this was open, and it was right
to: this is the same wrong-owner shape as the three defects fixed in the previous
commit, except this one is introduced BY this PR rather than merely missed by it.

THE DEFECT. Typing an unannotated field from a constructor assignment
(`var conn; Host() { conn = Alpha(); }` binds `conn` on the CLASS scope) is this
PR's whole point. `emitDartFieldAssignmentBindings` correctly declines to WRITE
that binding when a member body rebinds the name — but the shadow set gated
writes ONLY. `collectDartBodyShadows` had exactly one call site, inside the
bare-name write branch. Nothing consulted it on the read side, so a bare-name
READ of a shadowing binder the resolver cannot type walked straight past the
local and hit the field binding this feature mints:

    class Host {
      var conn;
      Host() { conn = Alpha(); }
      void probe(List<Beta> xs) {
        for (final conn in xs) { conn.inner(); }   // conn is a Beta element
      }
    }
    // resolved Alpha.inner, not Beta.inner

Reproduced in SEVEN binder shapes, not the one the review reported: for-in
(`final` and `var`), untyped formal parameter, plain local `var`, catch binding,
closure parameter, and record pattern. Delete the constructor and the same read
emits NOTHING — which is what proves this PR introduced it. "No edge" became
"wrong edge", the one failure mode compound-receiver.ts:519-537 exists to prevent.

THE FIX uses `Scope.ownsReceivers` (#2701), the primitive that already exists for
exactly this, rather than inventing a mechanism. `scope/walkers.ts` consults
`typeBindings` FIRST at every scope and only then honours the mask, so a shadow
the resolver CAN type still wins — an annotated `void probe(Beta conn)` keeps
`Beta`, because `synthesizeDartSignatureBindings` anchors parameter bindings on
the same body node and they land on the same Function scope. The mask fires only
where the alternative was a fabricated type.

Plumbing follows TypeScript's `@receiver-owner.this` precedent: the marker rides
the same synthesized match as `@scope.function` and sits outside the `@scope.`
namespace so `anchorCaptureFor` cannot mistake it for the anchor. Dart differs
only in that its function scopes are synthesized in captures.ts rather than
declared in the .scm, so the names travel as capture TEXT — a `CaptureMatch`
carries no AST node, so the reader cannot re-derive them.

SCOPE, and the costs taken knowingly rather than hidden. The mask is
`shadows ∩ fields` and nothing wider. Masking every locally bound name would
also fix a library-level `var logger = Logger();` shadowed by a loop variable,
but it changes resolution for code this PR never touched. Three consequences are
documented on `dartShadowedFieldsCapture`, not buried: the wider case is left
open; an ANNOTATED field shadowed by a binder is masked too (correct Dart, but it
touches resolution predating #2807); and `mixin` bodies are reached, since the
grammar gives them a `class_body`.

PERFORMANCE, measured rather than asserted. The mask is emitted eagerly in Pass A,
where `collectDartBodyShadows` used to be lazy — the replaced comment recorded
87-100% of eagerly built sets being discarded, ~15% of Dart emission. Actual cost
on the scope-capture large corpus, median of 3: 405.6ms with the mask vs 390.0ms
without, ≈ +4%. Fingerprint and capture_groups are byte-identical across both
arms, so no corpus fixture emits a mask at all — that 4% is the cost of the CHECK
alone. Not visible to `bench/scope-capture`, which gates the scaling RATIO and is
blind to a linear constant factor; stated here because the gate cannot state it.
(3 samples per arm, blocked not interleaved — an estimate, not a rigorous number.)
A per-file memo keyed by node span makes both passes share one walk per body, so
the write side no longer pays a second one.

SCHEMA_BUMP 40 -> 41 with its exact-value pin, since capture emission changed.
Re-check against origin/main immediately before merge — main was 39 at commit time.

Mutation-verified both directions, which is the part that matters:
  - unwire `scopeOwnsReceivers`, rebuild -> exactly 2 rows red
    (`loop-var-read-does-not-see-the-field`, `pattern-read-does-not-see-the-field`),
    83/85 green.
  - over-widen the mask (drop the `shadows.has` test) -> 28 Dart rows red,
    including `unshadowed-read-in-a-shadowing-class-still-resolves`.
The three control rows stay green under the first mutation BY DESIGN — they guard
overreach, not the defect; the second mutation is what proves they are live. Pre/post
on the trigger row: `{Class:Alien, Alien.inner#0, Outer.inner#0}` -> `{Class:Alien,
Alien.inner#0}`, so no row can pass vacuously.

Matrix 80 -> 85 tests. Sweep 3220 passed (was 3215; exactly +5). tsc clean. All four
capture gates green: receiver-resolution OK, scope-capture PASS (15 languages, no
fingerprint moved, nothing rebaselined), callable-value-flow PASS, swift golden 9.

* fix(ts,js): let each language name its own class-field node type

CI caught a defect the whole review round missed. `grammar-literal-validation`:

    1 dead grammar literal(s) found:
      - node-type "field_definition" — languages/typescript/captures.ts:0
        — not valid in [typescript]

`isStaticClassFieldBinding` held BOTH spellings in one set —
`public_field_definition` (TypeScript) and `field_definition` (JavaScript) — so
that one predicate could serve both languages. But the predicate lives in
`typescript/captures.ts`, and the gate checks every literal against the grammar
of the FILE it appears in. `field_definition` is not a TypeScript node type.

The literal was NOT dead code: `javascript/captures.ts:42` imports the predicate
and calls it against real JS nodes, so the guard worked. The gate is still right
to fail it, and for exactly the reason this predicate's own docblock gives for
preferring `hasKeyword` over a node-type test — "a node-type test silently stops
firing on a grammar bump and every static field starts retyping its instance
twin again". A literal already dead in its own file is that failure shipped
pre-broken: nothing in the TypeScript file would ever have told us.

Each language now names its own node type and passes it in
(`TS_CLASS_FIELD_DEFINITION_TYPES` / `JS_CLASS_FIELD_DEFINITION_TYPES`), so every
literal is checked against the grammar it belongs to. The `hasKeyword` logic and
the static/instance reasoning stay shared and unchanged — only the node-type set
moves to the caller.

WHY THE LOCAL SWEEP DID NOT CATCH IT: I ran `test/integration/resolvers` and
`test/integration/cfg`. The gate is `test/integration/grammar-literal-validation.
test.ts`, in the parent directory. Scoping a sweep to the subdirectories a change
touches is precisely how a cross-cutting gate gets skipped.

grammar-literal-validation 4 passed. tsc clean. Full `test/integration` +
`test/unit/scope-resolution`: 6305 passed, 14 failed — all 14 in e2e/environment
suites (fts-extension-e2e 9, analyze-heap-oom-e2e, cli-e2e,
analyze-wal-checkpoint-failure, plus interproc-taint and parse-impl-env-reads,
which BOTH pass in isolation and fail only under 28-worker load). CI runs the
same files green.

* test(dart,ts): pin all seven read-side binder shapes; correct a wrong accepted-cost claim

Two review findings, one of which turned out to be a documentation defect rather
than the design defect it was filed as.

S8 — THE READ-SIDE FIX PINNED 2 OF THE 7 SHAPES IT REPORTED REPRODUCING.
`ab2f48c17` reported the wrong-edge defect reproducing in seven binder shapes and
landed rows for two. The stated mitigation was that all seven route through one
`collectDartBodyShadows` enumeration whose completeness the grammar-derived
coverage guard protects. That mitigation is NARROWER THAN CLAIMED: the guard
filters `nodeTypeInfo` on `type.includes('pattern')`, so it covers the pattern
family and NOT catch bindings, closure parameters, plain locals, or formal
parameters. Narrowing `addDartBinderName`'s catch arm would have turned no row red.

All seven were re-measured by unwiring `dartScopeOwnsReceivers` and rebuilding.
Every one gained the wrong edge `Outer.inner#0` — none had to be dropped as
non-reproducing. Five new rows: formal parameter, plain local `var`, catch
binding, closure parameter, for-in `var`.

Non-vacuity established structurally, not by assertion: the Dart AST was dumped
first to confirm each fixture produces the node `addDartBinderName` actually
inspects (`formal_parameter`, `initialized_variable_definition`,
`catch_parameters`, `for_loop_parts`). The catch row uses a bare `catch (zf)`
rather than `on Err catch` deliberately — an `on` clause names a type, which
would make the row measure type resolution instead of the mask.

S7 — THE ACCEPTED-COST COMMENT WAS WRONG, AND THAT IS THE FINDING.
It claimed dropping a static field's binding trades a wrong edge for a missed one.
Measured on a same-name twin, that is false:

    read                     with the drop      without it
    this.p  (instance twin)  Outer  correct     Alien  wrong
    Host.p  (static twin)    Outer  WRONG       Alien  correct
    Host.q  (static, no twin) none — missed     Alien  correct

The wrong edge did not disappear. It MOVED to the static read, which now picks up
the instance twin's type. Only the no-twin case is a genuine missed edge. The
trade is still right — `this.p` is far more common than `Host.p` — but it was
documented as safer than it is, and a reader deciding whether to revisit it was
being given the wrong picture.

NAMESPACING WAS EVALUATED AND DELIBERATELY NOT DONE. `Host.p.hit()` resolves
through `foldReceiverChain` in shared `compound-receiver.ts`, which explicitly
discards whether a chain's base was a class reference or a value (:519-527). The
class-constant bit exists only on the text-cascade path (`currentIsClassConstant`)
and is consumed solely by `isConstructionSelectorHop`; TS/JS take the fold, not
the cascade. `Scope.typeBindings` is `ReadonlyMap<string, TypeRef>` with no static
field. `ownsReceivers` cannot help — it is a suppressor that can only REMOVE a
binding, never route to a second one. A real fix needs `FoldState` to carry the
bit plus a key convention in shared code (an AGENTS.md:42 hook if not
language-neutral), it crosses the worker boundary so it needs a SCHEMA_BUMP, and
`compound-receiver.ts:826` iterates every binding for `fieldFallback` so a
namespaced key would leak straight back in as an ordinary field. Not a cheap or
safe change — and it would have been made with ZERO existing tests pinning
static-read behaviour.

So: smallest safe step instead. Two rows pin the measured behaviour
(`static-read-of-a-same-name-twin-picks-up-the-instance-type` asserts the positive
wrong target, not an empty set; `static-read-without-a-twin-loses-its-type` is a
known-gap), and the comment now says what actually happens. Anyone who revisits
this starts from measurements rather than from a claim.

No SCHEMA_BUMP: the `captures.ts` change is comment-only — verified, the diff has
no non-comment added lines.

Mutation red-rows 2/85 -> 7/90; each new row fails with a strictly larger set
(`+Outer.inner#0`), so none can pass vacuously. Overreach control still live:
dropping `shadows.has` turns 28 rows red including
`unshadowed-read-in-a-shadowing-class-still-resolves`.

Matrix 85 -> 92 tests. Sweep 3231 passed, 0 failed. tsc clean. All four gates
green, no fingerprint moved, nothing rebaselined.

* fix(python): stop a dotted callee from fabricating a constructor type

S4 and S5 from the review round. They are ONE defect, not two, and the real one
is wider than the review described. Both live in a 32-line block THIS PR adds
(`@@ -116,0 +117,32 @@` — a pure addition), so neither is pre-existing.

THE DEFECT. `constructorCallTypeName` rejected only a callee rooted at the
receiver and returned every other dotted callee whole to `resolveTypeRef`, which
resolves dotted names through `QualifiedNameIndex` — and that index matches the
TRAILING SEGMENT against a class of that name even when the callee is a method on
an unrelated object:

    class Alpha:
        def ping(self): return 1
    class Factory:
        def Alpha(self): return "not an Alpha"    # a METHOD
    class Host:
        def __init__(self, f): self.svc = f.Alpha()   # svc is a str
        def run(self): return self.svc.ping()
    # measured: Host.run -> Alpha.ping, fabricated

WIDER THAN FILED: the review framed the trigger as a callee rooted at an
`__init__` PARAMETER. Measured, the root's binding form is irrelevant — a
module-level variable (`shared_factory.Alpha()`) fabricates identically. Any rule
written against what the root binds to would have fixed half the defect and left
the other half looking fixed. Both fabrications now have rows.

S5 IS A SYMPTOM, NOT A SECOND DEFECT. `self.conn = Outer()` then
`self.conn = Registry.get()` typed the field as `"Registry.get"` (resolving to
nothing, so the edge vanished) only because the dotted arm accepted
`Registry.get` as a constructor in the first place. Once dotted callees yield no
candidate, there is nothing weak left to displace with and `Outer` survives. So
`>=` is untouched and NO second mechanism was added: between two REAL
constructions last-write-wins is correct, and the existing `ReassignedField`
matrix row depends on it. Tightening the tie-break would have been the wrong fix
to a symptom.

THE FIX: accept a bare `identifier` callee only. Refusing ambiguous evidence at
CAPTURE time rather than resolving-then-rejecting is deliberate — the target-kind
route is not reachable from this file (`resolveTypeRef` already filters
`TYPE_KINDS`; the fabrication comes from a trailing-segment match in
`scope/walkers.ts`), and the root-alias route would collide with PR #2828, which
is rewriting exactly how an unaliased dotted namespace import resolves. This
change is orthogonal to #2828 by construction: it changes what is CAPTURED, never
how a name is looked up, and touches none of its files.

WHAT THE DOTTED ARM WAS ACTUALLY BUYING: nothing. The review (and this PR's own
docblock) justified it with `self.u = models.User()`. Measured, that shape emits
NO edge before or after this change — an instance field's binding lands in CLASS
scope, which never reaches the namespace split. The shape that really resolves is
the module-level local `u = models.User()`, which comes from `query.ts` and is
untouched here. The arm's entire measured contribution was fabrications, which is
what made the fix cheap.

#2828 COMPATIBILITY, checked not assumed: `import pkg.user` -> `self.u =
pkg.user.User()` resolves to nothing both before and after, so this cannot stop it
resolving. No test row pins that shape ON PURPOSE — asserting its current empty
state would plant a tripwire that goes red the moment #2828 lands. If #2828 also
teaches the FIELD path the namespace split, re-enabling dotted field callees
becomes a live option; the docblock says so, and says why redoing it capture-side
would re-open the fabrication.

SCHEMA_BUMP 41 -> 42 with its pin. This is parse-time capture emission: after the
fix `self.svc = f.Alpha()` emits no `@type-binding.constructor` capture at all, so
a v41 warm cache replays the pre-fix capture set for byte-unchanged files and
keeps serving the fabricated edge (GUARDRAILS.md:34). A within-PR re-bump, not a
collision fix — 40/41/42 are all this unmerged branch's, and `origin/main` is at
39. Re-check against origin/main immediately before merging.

Mutation-verified in BOTH directions, which is what shows the fix is placed at the
right width rather than merely working:
  - revert the fix     -> exactly 3 red: both S4 fabrication rows + the S5
                          displacement row (8 green)
  - reject EVERY callee -> exactly 3 red: the three positive-typing rows (8 green);
                          the S4 rows correctly stay green
The two mutations hit DISJOINT row sets — too loose and too tight each break a
different half.

No row asserts an empty set: the three "must not type" rows call `Alien.ping()` as
a witness so a regression SWAPS a target in rather than emptying. Non-vacuity is
asserted in the test itself — one guard checks every caller node is live, another
asserts the `Alpha` class / `Factory.Alpha` method name collision the fabrication
NEEDS is actually present, so the rows cannot rot into passing for the wrong reason.

Sweep 3268 passed, 0 failed. Python unit + python.test.ts 342 passed. tsc clean.
All four gates green — no bench cell moved, nothing rebaselined.

perf(cpp): index qualified namespace members once per pipeline run (#2788) (#2794)
* perf(cpp): index qualified namespace members once per pipeline run (#2788)

`resolveCppQualifiedNamespaceMember` walked every parsed file — rebuilding a
per-file `scopesById` map each time — once per qualified `ns::member()` call
site, so the scope-resolution emit phase cost O(callsites x scopes). On a
1,473-file C++ repo that was 25.3 min of a 33-min analyze, with 75% of total
self-time in this one function. Its inner `findMemberInNamespaceTransitive`
compounded it: each recursion step filtered `scopesById.values()` by parent,
O(scopes^2) per file on its own.

This is the same bug #1990 fixed in the sibling ADL path (`pickCppAdlCandidates`
-> `AdlCandidateIndex`), so it gets the same fix: a `QualifiedNsMemberIndex`
(receiver simple name -> member simple name -> callable defs) built lazily once
per `parsedFiles` identity and reset by `clearCppInlineNamespaces`, which runs
from `cppScopeResolver.loadResolutionConfig` at the start of every pass. Per
call site the work drops to two Map lookups.

Ordering is preserved exactly — file-major, `parsed.scopes` declaration order,
a namespace's own `ownedDefs` before its inline-namespace children, depth-first
— because the caller takes `allHits[0]` for the single-hit case and
`narrowOverloadCandidates` is first-wins. Non-inline nested namespaces are
still not descended into, and same-name hits across inline children still
report `'ambiguous'` (#1564).

Measured with `PROF_SCOPE_RESOLUTION=1 analyze --force --index-only` on a
synthetic corpus (`namespace ns_i { inline namespace v1 { ... } }` plus 20
`ns_j::fn()` call sites per file):

| files | emit before | emit after |
|-------|-------------|------------|
| 100   | 153ms       | 16ms       |
| 200   | 704ms       | 24ms       |
| 400   | 3,293ms     | 42ms       |
| 800   | 16,898ms    | 78ms       |

Before, doubling the file count quadrupled emit; now it doubles. At 800 files
total scope resolution goes 17.2s -> 394ms.

Output is unchanged, verified rather than assumed: a full graph dump (sorted
nodes + relationships) from a baseline build at the parent commit and from this
one are byte-identical on all 134 `cpp-*` fixtures merged into a single repo
(1573 nodes / 1997 relationships) and on the 400-file synthetic corpus.
`test/integration/resolvers/cpp.test.ts` passes 334/334.

#1990 shipped its ADL fix without a scaling gate, which is how the bug class
came straight back here, so this adds one: `bench/cpp-qualified-ns` measures
`(t_large/t_small)/(1600/400)` — 0.93-1.21 indexed versus 3.45 for the old
per-call-site scan — alongside a fingerprint over every
`receiver::member -> outcome` the corpus resolves, and CI runs it with
`--check`. `test/unit/cpp-qualified-ns-index.test.ts` covers the cache
invalidation the index introduces.

* fix(cpp): address tri-review findings on the qualified-namespace index (#2788)

Multi-engine review of this PR (Claude swarm + ce-code-review, Codex
gpt-5.6-sol swarm + ce + adversarial) returned two P1s and five smaller
findings. All are fixed here.

P1 — the index defeated the pipeline's post-language memory release.
`scope-resolution/pipeline/phase.ts` evicts each language's files and then
calls `forceGc()`, on a stated premise that "This language's ParsedFiles are
now unreachable", sizing C/C++ at ~17-20GB on the Linux kernel. The
module-level `let qualifiedNsIndexSource` falsified that: it pinned the whole
`parsedFiles` array, and the index held defs reaching into those files'
scopes, until the *next* C++ pass cleared it — which in a single analyze never
comes. C++ is 7th of 16 in SCOPE_RESOLVERS, so the set survived nine later
language passes plus emit. Replaced with a
`WeakMap<readonly ParsedFile[], QualifiedNsMemberIndex>`, the pattern already
used by `moduleScopeIndexByPass` in `cpp/file-local-linkage.ts`.
`clearCppInlineNamespaces` still swaps in a fresh WeakMap, because the index
has a second input (`inlineNamespaceScopeIds`) the key cannot observe.
Measured with `--expose-gc`: 61.2MB retained after the caller drops the array
before, 0.1MB after.

The ADL twin (`adl.ts`) has the same pattern, so the hazard predates this PR —
but `pickCppAdlCandidates` returns early before `ensureAdlIndex` on
`noAdlSites`/empty `argInfoBySite`, so it rarely arms, whereas a qualified
`ns::member()` index arms on almost every C++ workspace. Moving the ADL twin
to a WeakMap is left as a follow-up.

P1 — the new bench could not see the regression class it exists to gate.
`callSites()` drew every receiver from `ns_${...}`, so the receiver lookup
never missed; production is the opposite, since Case 1.5 in
`receiver-bound-calls.ts` is reached by every plain-identifier receiver call
and misses on most. A rescan reintroduced only on the receiver-bucket-absent
path scored 1.279 and PASSED the old bench. The corpus now mirrors production
(~1 in 5 receivers name a declared namespace) and adds a namespace reopened
across files, a same-name inline nest, a member declared at both namespace and
inline-child level, and call sites carrying a real `Callsite` so
`narrowOverloadCandidates`/`cppConversionRank`/
`isOverloadAmbiguousAfterNormalization` are inside the fingerprinted surface at
all. That same rescan now measures 4.538 and FAILS; defeating the dedup now
fails the fingerprint arm where it previously passed byte-identical. The
fingerprint moved once, deliberately, for the corpus expansion — recorded in
`_rebaseline_2788_review`, explicitly not precedent.

Also fixed:

- Unbounded recursion aborted analyze. `collectNamespaceMembers` recursed per
  inline child with no bound and threw an uncontained `RangeError` at inline
  depth 8000 (`phase.ts`'s try has a `finally`, no `catch`), and a receiver
  *miss* paid full recursion where the deleted walker skipped on a name
  mismatch. An explicit work-stack alone would only have converted that into
  an OOM at depth 6000, because the eager table was quadratic in memory too:
  for a depth-D chain it legitimately holds D(D+1)/2 entries, since `v2::foo()`
  is a valid receiver at every level. Replaced with a lazily-queried node graph
  (per-scope own-member buckets plus direct child links, resolved on demand and
  memoized per receiver+member). Build is now linear; depth 100000 costs 133ms
  where 8000 previously threw.
- "#1990 shipped without a scaling gate" was false. #1990 did ship
  `test/integration/cpp-adl-benchmark.test.ts` (f1b843838). Corrected in the
  bench header and the CI step comment. The accurate point is narrower and
  stronger: that bench asserts `callsResolved === 0`, so it never drives the
  qualified-receiver path, and it is `skipIf(!GITNEXUS_BENCH)` while the only
  step setting that variable lists neither C++ bench — so it has never run in
  CI. Wiring it in is a follow-up.
- "Ordering is load-bearing" was not a live property: `allHits[0]` is only
  reached at length 1, and both tail branches return `'ambiguous'`. Order is
  still preserved for byte-identity with the pre-#2788 walker; the comment now
  says that instead, and the test named for ordering is renamed to the
  parent/inline-child visibility it actually asserts.
- "Same contract as `ensureAdlIndex`" overstated parity — the sibling ships a
  `validateAdlSeqCoverage` guard because it reads
  `seqByNodeId.get(...) ?? 0`, which can silently collapse candidates. This
  index has no analogous defaulting read, so no guard is added; the comment now
  says why.
- Two coverage gaps closed, both mutation-verified: cross-file merge of one
  namespace reopened in two files (no existing test covered it — confirmed by
  making each file clobber the previous and watching only the new test fail),
  and the same-name inline nest whose dedup, when defeated, flips a resolved
  def to `'ambiguous'`.
- `resolveCppQualifiedNamespaceMember`'s JSDoc now names both production call
  sites, including the callsite-less `resolveAdlCandidates` path.
- Memoized candidate buckets are frozen, so a future in-place sort in
  `overload-narrowing.ts` throws instead of silently corrupting later
  resolutions now that the array is shared across call sites.
- `_scaling_note`'s "measured 0.93-1.21" band did not reproduce; it is now the
  honestly observed 1.28-1.45, with the small arm widened to ~14ms (halves the
  spread) and a triage line saying a scaling failure is a timing signal to
  re-run, unlike the deterministic fingerprint arm.

Verification: 840,000 differential probes against the pre-#2788 walker
extracted from base, 0 mismatches, plus 48,000 candidate-order comparisons,
0 mismatches. cpp resolver integration suite 334/334. Unit suite 10/10.
tsc, eslint, prettier clean. Bench --check PASS.

* fix(bench): escape the NUL separator so measure.mjs stays a text file

The fingerprint key separator was written as a literal NUL byte instead of the
`\u0000` escape. Git classifies any file containing a NUL as binary, so the
whole bench showed as `Bin` with no diff on GitHub and could not be reviewed —
the same defect this branch already fixed once before the tri-review.

Escaping it is byte-for-byte equivalent at runtime (both produce U+0000), so
the committed fingerprint is unchanged and `--check` still passes.

* refactor(cpp): quality cleanups from a four-angle review of the #2788 series

Reuse, simplification, efficiency and altitude passes over the diff. No
resolution behaviour changes: the bench fingerprint is unchanged and the C++
resolver integration suite still passes in full.

Efficiency

- The `Object.freeze` added in the review-fix commit to close an aliasing
  residual costs 4.6x on the narrowing path — V8 moves frozen arrays to
  PACKED_FROZEN_ELEMENTS, off the fast path for the `.filter`/`.map`/`.some`
  runs `narrowOverloadCandidates` does at every multi-candidate call site.
  The hazard it guards is already a compile error (both the memo and the
  parameter are `readonly SymbolDefinition[]`), so it is now a dev-only
  tripwire. Gated on `isSemanticModelValidatorEnabled()` — the repo's opt-IN
  form used by `phase.ts` and `validate-bindings-immutability.ts` — not
  `adl.ts`'s opt-out `NODE_ENV !== 'production'`, which would keep paying the
  cost in CLI runs where `NODE_ENV` is unset. Large bench arm 100.3 -> 70.6ms.
- The index build scanned every scope in every file twice; pass 1 now collects
  `[scope, node]` pairs for pass 2 to iterate. 800k scopes 14.40 -> 8.21ms.
- `simpleNameOf` uses `lastIndexOf('.')` + `slice` instead of
  `split('.').pop()` (83 -> 24 ns/call), semantics verified byte-equivalent
  over 12 edge cases including `undefined`, `''`, `'a.'`, `'.b'` and `'a..b'`.
- The per-call `hookCtx` literal is hoisted to a module const.
- The bench's fingerprint pass resolved 960k call sites to produce 5,800
  distinct outcomes; it now dedups on the key it already builds. Bench wall
  time 2.4 -> 1.9s, fingerprint byte-identical.

Reuse

- `bucketOwnMembers` used an inlined `Function | Method | Constructor` compare;
  it now calls the canonical `isOverloadableCallable`. `graph-bridge/ids.ts`
  already carries a note that inlining this list recreated twin-list drift once.

Altitude

- `adl.ts` had the same retention defect this series just fixed next door: a
  module-level `let adlIndex` + `let adlIndexSource` strongly pinning the whole
  `parsedFiles` array until the next C++ pass, which in a single analyze never
  comes. Converted to the same `WeakMap` shape. Measured with `--expose-gc`:
  89.11MB retained after the caller drops the array before, 0.17MB after. Six
  file-local helpers now take the index as a parameter; no exported signature
  changed.
- The index's freshness depended on `clearCppInlineNamespaces()` being called
  from another file, guarded only by a warning paragraph. An epoch bumped in
  both `populateCppInlineNamespaceScopes` and the clear is now stored with the
  memo, so a missed clear degrades to a rebuild instead of a stale answer —
  confirmed by driving inline state mid-pass without the clear. Roughly line
  neutral, since it replaces most of the paragraph.
- `test/integration/cpp-adl-benchmark.test.ts` is wired into the
  `GITNEXUS_BENCH` step. It is `skipIf`-gated and was absent from that step's
  explicit file list, so #1990's ADL emit-scaling guard had never executed in
  CI. It passes; ~50s added to a 25-minute job. `cpp-pipeline-benchmark.test.ts`
  is deliberately NOT wired: it costs 115s for guards covering generic
  per-language pipeline scaling that nothing here touches.

Simplification

- Deleted a comment referencing a `inlineChildrenByParent` map that only ever
  existed inside this branch's own first commit, so "the legacy map" pointed a
  reader at code that never shipped.
- Dropped three unreachable `undefined` guards (`strict: false`, no
  `noUncheckedIndexedAccess`), keeping the load-bearing `visited` check.
- Compressed the `rootsByReceiver` doc from 17 lines to 7 — it was the longest
  comment in the file and guarded the least consequential property — the
  `validateAdlSeqCoverage` paragraph from 7 lines to 3, and turned three
  restatements of the uncaught-throw and dedup arguments into pointers.
- Test fixtures: dropped the dead `'Module'` union arm, added a one-line `ns()`
  builder for the nine hand-written scope literals, and moved the file to
  `test/unit/scope-resolution/cpp/` where every other C++ scope-resolution unit
  test lives. 403 -> 337 lines, same 10 tests, and the cross-file mutation check
  still fails exactly one test.

Not done, and why: merging this index into `AdlCandidateIndex` (they key on
different names with different inline-transparency depth — a refactor with
correctness risk, not a cleanup); `ScopeTree.getChildren` (trades in-memory
`parsed.scopes` for store hits on a hot path); a shared `cpp/` util for the five
pre-existing `simpleName` copies; sharing fixtures across the bench/test
boundary (no precedent in this repo); and an exact-count arm for the bench,
which is a gate redesign worth its own change.

* fix(rust): let the qualified-call filter see inline modules

The negative filter added in #2741 builds its set of known module names from
FILE PATHS, so an inline `mod x { … }` — which appears in no path — was absent
from it. Every module-qualified call into an inline module was therefore
rejected before any candidate channel ran, which is a hole in that optimisation
rather than in the resolution logic it guards.

The per-pass index now unions the file-derived names with inline module names
taken from the scope model: a `mod` declaration binds a `Namespace` def locally
in the declaring scope, and that binding is the only place an inline module's
name exists. Collected in the same walk that already builds the module → scope
map, so it costs no extra pass.

Found while fixing #2742, where a correctly resolved call into `mod inner { … }`
still could not reach its target.

* fix(scope-resolution): try the namespace-prefixed node key before the bare one

`resolveDefGraphId` looked up the plain `qualifiedName` key first and only
retried with the `namespacePrefix`-qualified key afterwards. For the defs that
carry a prefix the qualified name is a bare TAIL, so the plain key happily
matched a same-named item at a different namespace depth in the same file and
returned it before the more specific retry was ever reached.

The namespace-prefixed key is strictly the more specific of the two, so it is
now tried first. Where no such node exists the lookup falls through to exactly
the previous order, which keeps the #1982 behaviour this retry was added for.

Without this, a call into `mod inner { fn dispatch }` resolved to the correct
definition and then mapped it onto the crate-root `fn dispatch` node — the
self-loop #2742 describes.

* fix(rust): qualify items by their enclosing mod chain so same-named ones stay distinct (#2742)

Node identity is `<label>:<file>:<qualifiedName>` and carried no module path, so
an inline `mod inner { fn dispatch }` and a crate-root `fn dispatch` in the same
file collapsed onto `Function:<file>:dispatch`, first-wins. Resolution already
picked the right definition — the target simply was not representable, so a
correct resolution still rendered as a self-loop and `impact` reported the real
callee as unreached.

The mechanism already existed: `qualifyRustImplTargetByModScope` has walked
`mod_item` ancestors for impl targets since #1982. Generalised to
`qualifyByEnclosingModScope` and applied to free items, so
`mod inner { fn dispatch }` becomes `Function:<file>:inner.dispatch`. Keyed
purely on the `mod_item` node type, exactly as the impl qualifier already was,
so it is a no-op for every language whose grammar has no such node.

Two constraints found by tests rather than by reading, both now encoded:

  - The helper normalised `::` to `.` unconditionally. With no enclosing `mod`
    that rewrote a top-level `impl a::Inner` from `a::Inner` to `a.Inner` and
    moved its node id away from the one the HAS_METHOD owner edge emits,
    breaking the #1975 scoped-impl ownership. It now returns raw text untouched
    when there are no mod segments, which also makes the change strictly
    additive for every id that has no enclosing module.

  - Qualification is scoped to items with no enclosing class/impl. A method
    already carries its owner's name, and that owner's id is mod-scoped by the
    impl qualifier, so qualifying the method again breaks the same byte-for-byte
    agreement. Same-named methods on same-named types in sibling modules
    therefore still collapse — a narrower residual than the free-item case fixed
    here, and one belonging to the owner edge rather than to this path.

* fix(storage): bump schema versions for the mod-qualified Rust node ids (#2742)

`INCREMENTAL_SCHEMA_VERSION` 24 -> 25 and `SCHEMA_BUMP` 31 -> 32.

Node ids change for every Rust item inside any `mod` block, and
`#[cfg(test)] mod tests` makes that close to every Rust repository. A pre-v25
index therefore holds ids an incremental top-up cannot reconcile — the old nodes
would simply be stranded — so the reuse gate has to force a full re-analyze. The
qualified name is computed in the parse worker, so a warm parse cache would
likewise replay the old unqualified ids and keep the collapse.

This branch originally claimed v24; #2708 took that number and merged first, so
it is renumbered to v25 here. That is exactly the collision the v29 note in
parse-cache.ts warns about, and re-checking against origin/main at rebase time
rather than at branch time is what caught it. #2708 did not touch `SCHEMA_BUMP`,
so 32 is free.

The version-pin test moves with the bump by design, including the new pre-v25
row in the reuse-gate table.

* fix(rust): stop mod-qualifying container ids while their owner edges stay bare (#2745 review)

#2742 re-keyed Rust node ids by the enclosing `mod` chain. The mint moved; the
owner-edge anchor did not. `findEnclosingClassInfo` mints a member's owner id
from the container's BARE `nameNode.text` and only follows a qualified shape when
the provider sets `classExtractor.qualifiedNodeId`, which Rust does not.

So every `struct` / `trait` / `enum` / `impl` declared directly inside a `mod`
got a node id that none of its member edges pointed at. Five lines of idiomatic
Rust were enough:

    pub mod engine { pub struct Config { pub retries: usize } }

    NODE     Struct:src/lib.rs:engine.Config
    DANGLING HAS_PROPERTY Struct:src/lib.rs:Config -> Property:src/lib.rs:Config.retries

The rows are discarded by the IGNORE_ERRORS COPY retry, so the struct silently
lost every field. A trait impl inside a `mod` additionally dropped its
METHOD_IMPLEMENTS edge outright.

The same gap put `impl a::Inner` inside a `mod` back on the #1975 rake that
`qualifyByEnclosingModScope`'s own docblock warns about. The impl-target branch
deliberately fires only for an UNSCOPED `type_identifier`; the new gate had no
such restriction and picked up the scoped targets that branch had just excluded,
minting `Impl:<file>:outer.a.Inner` against an anchor still reading
`Impl:<file>🅰️:Inner`.

The member side was already excluded via `!enclosingClassInfo`. This adds the
owner side, gated on `MEMBER_OWNER_NODE_TYPES` — derived from
`CLASS_CONTAINER_TYPES`, which is already the single source of "this node type
owns member edges" and already carries an INVARIANT note binding it to
`CONTAINER_TYPE_TO_LABEL`. A language adding a container therefore cannot gain a
mismatched id shape here without also failing that invariant. Keyed purely on
tree-sitter node types, so no language name enters shared ingestion.

`union_item` is listed too: its fields are captured as Property but it is not a
recognized owner, so they carry no HAS_PROPERTY edge and cannot dangle — it is
here so a union's id keeps the same shape as the struct beside it.

Containers still collapse across sibling modules, exactly as before this fix.
That residual belongs to the owner edge, and is not worked around here.

Regression tests use the UNFILTERED `findDanglingEdges(result)`. Every other
dangling assertion in `rust.test.ts` passes `['HAS_METHOD']`, which is precisely
why the HAS_PROPERTY breakage shipped with a green suite. They assert the NODE
id rather than only the edge's anchor, because the anchor was already bare while
the bug was live — an edge-only assertion passes in both builds. All four fail
when the new gate clause alone is reverted.

* fix(rust): resolve modules nested inside an inline mod (#2745 review)

The #2730 self-loop survived one `mod` deeper:

    pub mod outer {
        pub mod tools { pub fn dispatch() {} }
        pub fn dispatch() { tools::dispatch(); }
    }

    CALLS outer.dispatch -> outer.dispatch          <- the #2730 symptom
    NODE  outer.tools.dispatch                      <- correct target, unlinked

Two gates were blind to a nested inline module, so the hook refused and the shared
lexical tier bound the call to the enclosing same-name `dispatch`:

`knownModuleNames` was collected by walking `moduleScopeByFile`, which maps a file
to its ROOT `Module` scope only. A `mod` nested inside an inline `mod` binds in the
parent module's scope, so the walk saw depth-1 inline modules and missed every
nested one — `tools` never entered the set and the negative filter rejected the
qualifier before any candidate ran.

`declaresSubmodule` had the same root-only assumption, so even with the name known
the candidate `outer::tools` was never yielded.

Both now read the def index. Names come from every `Namespace` def; inline module
PATHS are derived from the members' `namespacePrefix` rather than from the `mod`
defs, because a `mod` def carries no nesting information of its own — inside
`mod outer { mod tools { … } }` the inner def is `qualifiedName: 'tools'` with NO
`namespacePrefix`, while every def within it is stamped `outer.tools`. A
`Namespace` scope also owns its OWN def rather than its children's, so the scope
tree cannot answer this either: the `mod outer` scope lists `outer`, never `tools`.

Restricted to non-empty prefixes, so this stays a DECLARATION check. Including
file-derived modules would let an undeclared or `cfg`-gated file on disk outrank a
real `use` binding — the regression #2741's review already fixed once. File-backed
submodules therefore keep going through the binding check.

A module with no defs at all is absent from the set, which is harmless: it has no
member for a qualified call to resolve to.

Cost is one pass over an already-resident def index, memoized per resolution pass
on the existing WeakMap — the same order of work as the binding walk it replaces,
and it subsumes it. `isLocalNamespaceBinding` was going to single-source the
duplicated "locally declared submodule" predicate the review flagged; deriving
paths from members removed the second copy outright instead.

Regression fixture covers depth 2 and depth 3, so the fix is depth-agnostic rather
than depth-2 special-cased.

* fix(rust): let an imported type outrank a same-named module (#2745 review)

Widening the negative filter to inline `mod` names let a type-qualified call
through whenever a module happened to share the type's name. The
crate-root-relative candidate then captured it:

    // src/lib.rs
    pub mod Buffer { pub fn with_capacity() -> usize { 111 } }
    // src/b.rs
    use crate::c::Buffer;                        // the real target lives in c.rs
    pub fn call() -> usize { Buffer::with_capacity() }

    base: (no CALLS edge — unresolved)
    PR:   CALLS b::call -> Function:src/lib.rs:Buffer.with_capacity   <- fabricated

`ids.ts` states the doctrine this broke: a missing edge is the correct failure
direction for a graph whose consumers include `impact`; a fabricated caller is not.
The base produced the missing edge and the PR produced the fabricated one.

That third candidate is the loosest of the three — a guess at a crate-root-relative
path the caller never wrote, kept for 2015-edition style. In Rust 2018 a bare first
segment resolves in the CALLER's module, so a local binding for that segment
settles the question: it is now skipped when the head names anything non-module in
the caller's own module. Candidates 1 and 2 are untouched, and they run first, so
the legitimate `use crate::tools;` path is unaffected.

The binding lookup goes through `lookupBindingsAt`. A first attempt read
`Scope.bindings` directly and the guard never fired: a `use` binding is finalize
OUTPUT and absent from the scope's own local table, which is exactly the
imported-type case being guarded. Contract I8 in `contract/scope-resolver.ts`
requires that channel anyway.

The regression test asserts the forbidden TARGET rather than an empty edge set, and
separately asserts the module member still exists as a node — otherwise the test
would pass just as well if the call went unresolved for some unrelated reason, or
if the module node disappeared entirely.

* fix(scope-resolution): try the namespace-prefixed name on the TAGGED keys too (#2745 review)

`resolveDefGraphId` gained a namespace-prefixed retry for the plain qualified key
in this PR, but the five tagged keys above it — template constraints, parameter
types, parameter shape, arity, template arguments — kept composing from the bare
`qualifiedName`.

For a namespace- or `mod`-qualified def those keys are simply dead:
`node-lookup.ts` registers them under the QUALIFIED name (`inner.dispatch#0`)
while this side built `dispatch#0`. The keys exist to separate overloads, so a
mod-scoped overload set was relying on whichever later key happened to catch it.

Verified as a miss rather than a mis-hit before changing anything — an end-to-end
run with a crate-root decoy of the same name and arity binds correctly — so this
is hygiene, not a live bug. Worth doing while the code is open rather than leaving
five keys dead and the behaviour dependent on fallback order.

Both name forms now go through one `lookupTagged` helper, most specific first, so
a sixth tagged key cannot be added with the bare form only. That also removes the
five hand-repeated `qualifiedKey(...)` / `nodeLookup.get(...)` pairs.

Also pins the C++ `EXTENDS` retarget this PR's reorder produces.
`cpp-two-phase-dependent-base-cross-ns-deep` declares a global `Inner` decoy
alongside `ns:🅰️🅱️:Inner`; the base's `qualifiedName` is a bare `Inner` with the
path on `namespacePrefix`, so only the prefixed key separates them, and only if it
runs first. The improvement was riding unasserted in a Rust-scoped PR.

The captures golden covers every `rust-*` fixture, so the three fixtures added by
this review series drift it; regenerated with UPDATE_GOLDEN=1.

Verified: 785 tests across cpp / csharp / rust resolvers and the
callable-id-lockstep unit test.

* fix(rust): keep a mod declared inside a fn from hoisting above the callable (#2745 review)

`fn wrapper() { mod helper { fn dispatch } }` minted
`Function:<file>:helper.wrapper.dispatch@2:8` — the mod segment composed OUTSIDE
the enclosing-callable prefix, inverting the real nesting.

Nothing dangled: the `@line:col` suffix already makes a function-local callable's
id unique, which is also why the mod segment adds no identity in this position. The
path simply read as a lie about the source. It is now skipped rather than
reordered — interleaving two qualifier passes to fix the order would be real
machinery for a shape whose ids are already unique.

Also folds in the three documentation and structure findings from the same review:

- The 4-clause gate is extracted to a named `qualifiesByEnclosingModScope`, matching
  the two conditions directly above it in the same function, which were already
  named consts.
- `qualifyByEnclosingModScope`'s docblock documented only the impl-target contract
  even though the generalized name has had a second, looser caller since #2742. It
  now states both, and says which gate belongs to which — that gap is what let the
  #1975 scoped-impl regression through in the first place.
- The "cheap rejection BEFORE any index work" comment was no longer true:
  `passIndexFor` walks the def index on its first call in a pass. Corrected rather
  than left to mislead the next reader into thinking the filter is free. What it
  still buys — skipping the per-site candidate search, the part that scales with
  the workspace — is stated instead.

Verified: 279 tests across the Rust resolver suite and the Rust scope-resolution
unit tests. Captures golden regenerated for the extended fixture.

* test(storage): move main's SCHEMA_BUMP pin to 32 for the mod-qualified ids (#2745 review)

`#2736` added a pin asserting `SCHEMA_BUMP === 31` on main, which arrived on this
branch through the merge of main while `0062a5c2` had already bumped the constant
to 32. Neither side conflicted textually — the pin and the constant live in
different files — so the merge was clean and the test failed instead.

That is the pin working as designed: it exists so a bump cannot ride along
unnoticed, and this is the fifth time a SCHEMA_BUMP collision has been caught by a
guard rather than by review. Updated to 32 with the reason recorded inline.

`INCREMENTAL_SCHEMA_VERSION` needs no second bump: 25 was introduced by this
unmerged branch, so no released index carries it, and its own pin in
`call-summary-schema-version.test.ts` is already consistent.

Verified: 119 tests across the parse-cache, schema-version, incremental-orchestration
and the two identity suites that arrived with the merge.

* test(bench): rebaseline the Rust capture fingerprint for the three new fixtures (#2745 review)

CI caught what I missed:

    [scope-capture --check] FAIL: rust: capture fingerprint drift
      (got 05acbaca..., expected 90fda086...)   fixture_count 202

`bench/scope-capture` fingerprints the whole `rust-*` fixture corpus, so the three
fixtures added by this review series drift it. I rebaselined the
`rust-captures-golden` snapshot and stopped there — a new fixture is a call site of
BOTH, and updating only one is how this reached CI red.

This is the same class as PR #2743's headline finding, from the other direction: an
id-shape change makes every synthetic corpus a call site, and the author fixed the
unit-test fixture and missed the bench. Here it is a fixture-count change rather
than an id-shape change, and the review that flagged the #2743 lead as "REFUTED,
bench/ has no Rust node-id corpus" was right about node ids and wrong about the
corpus fingerprint. Noted for the next author in the baseline entry itself.

Verified as pure corpus growth rather than a capture-logic shift: removing ONLY the
three new fixture directories and re-running reproduces the prior fingerprint
exactly (196 fixtures, capture_groups_fp 3432), and restoring them gives the new
one (202, 3556). `emitRustScopeCaptures` is untouched by this series. Scaling 1.022
local / 1.057 CI, well inside the 1.5 budget.

`bench/python-scope` globs `python-*` only and is unaffected; no other bench walks
the Rust corpus. `--check` now PASSes for all 15 languages.

* fix(resolution): resolve constructor-expression receivers (#2708)

`Service(db).do_work()` emitted no CALLS edge, so the caller was missing
from `impact(direction: "upstream")` and `context()` while the two-step
spelling of the same call (`s = Service(db)` then `s.do_work()`) resolved.

The receiver reaches `resolveCompoundReceiverClass` intact — Case 0 in
`receiver-bound-calls` routes it there because the text contains `(`. The
free-call branch then only knew one shape: a function whose return-type
binding names a class. A class has no return-type binding, so `Service`
resolved to nothing and the member call was dropped.

Handle the constructor shape: in languages that construct without a `new`
keyword (Python, Kotlin, Swift, Scala) a free call naming a class IS a
constructor call, so the expression's type is that class. The existing
return-type path still runs first and wins, keeping this strictly
additive — `new`-keyword languages never reach the new line because their
receiver text keeps the keyword (`new Service(db)`), which matches no
class binding.

Verified on the issue's 4-file repro: `route_inline` now emits
`CALLS → Service.do_work` and `impactedCount` goes 1 → 2.

Note the issue's second ask — degrading `epistemic` to `lower-bound` when
a receiver goes unresolved — is NOT addressed here.
`computeEpistemicBoundary` keys only on the target's own heritage edges
and runs at query time against the index, while unresolved references
live in an in-memory `resolutionOutcomes[]` that is never persisted. That
needs unresolved-receiver counts in the index first, so it is left for a
follow-up.

Tests: new `python-inline-constructor-receiver` fixture plus three
integration cases (inline resolves, two-step still resolves, no
cross-class fan-out). Two of the three fail without the source change.
Full `test/integration/resolvers` suite passes (2928 tests) — the fix is
shared across every language, so no-regression coverage matters more than
the new cases. Python captures golden regenerated: additions only, no
existing digest changed, confirming capture output is untouched.

* refactor(resolution): state the construction rule once, cover every spelling (#2708)

The first commit fixed `Service(db).do_work()` by special-casing a bare
class-name callee inside the free-call branch of the compound receiver
resolver. That was the right rule in the wrong place: it covered one
surface syntax out of three, and asserted rather than declared which
languages it applied to.

Probing the same shape across languages showed the bug is wider:

  | spelling               | languages          | dropped before? |
  |------------------------|--------------------|-----------------|
  | `Service(db).m()`      | Python             | yes             |
  | `new Service(db).m()`  | JS/TS, Java, C#    | yes             |
  | `Service.new.m()`      | Ruby               | yes             |
  | both forms             | PHP, Swift, Dart,  | no — already    |
  |                        | Kotlin             | resolved        |

So the rule is stated once — "constructing a class yields an instance of
that class" — and the per-language surface syntax is declared through a
new `ScopeResolver.constructionSyntax` hook, matching how this file
already gates language-varying behaviour (`stripReceiverCastExpressions`,
`hoistTypeBindingsToModule`). Shared pipeline code names no language.

  - `bare: true`      — Python
  - `keyword: 'new'`  — JS/TS, Java, C#
  - `selector: 'new'` — Ruby, including the parenthesis-less `Service.new`
    spelling that reaches the chain walker rather than the call branch

Opt-in is per-language for two reasons. Correctness: `bare` would mistype
`stat(&st).field` in C, where a struct and a function may share a name.
Evidence: PHP, Swift, Dart and Kotlin resolve this shape already, so they
stay unwired instead of carrying a declaration that changes nothing —
each verified by diffing analyzer output between builds with and without
the change, not assumed.

The keyword gate also keeps a bare factory call honest: in a `new`
language, `makeOther(db).doWork()` still resolves through the factory's
return type and is never read as constructing a same-named class.

Tests: TypeScript fixture (inline `new`, a plain `.js` file for the
javascript provider, two-step, and the factory guard) and a Ruby fixture
(`Service.new` with and without an argument list, plus two-step). With
the source change stashed, the inline cases fail and the factory/two-step
cases still pass. The Python cases from the first commit are unchanged.

No Kotlin fixture: its cases passed without the change, so they would
document coverage this commit does not provide.

Full `test/integration/resolvers` + `test/unit/scope-resolution`: 4234
passed, 1 skipped. Ruby captures golden regenerated — additions only, no
existing digest changed.

* fix(resolution): only treat a construction selector as construction on the class itself (#2708)

The `selector: 'new'` rule fired on any receiver whose type was class-like,
which is true both when the receiver IS the class constant (`Factory.new`) and
when it is a value of that class (`factory.new`). `isClassLike(...)` cannot
tell those apart, so an instance receiver took the construction path too and
skipped the member lookup that should have run.

That replaced a CORRECT edge with a wrong one. Measured against the base build
on a class defining an instance method `new` returning a `Product`:

  factory = Factory.new; factory.new.run
    before this PR:  Product#run   (correct)
    after  this PR:  Factory#run   (wrong)

Track whether resolution currently sits on the class constant or on a value of
that class, and apply the selector rule only to the former. The head of a chain
is a class constant only when it resolved straight to a class binding rather
than through a typeBinding; every hop past it yields a value, so the flag
clears. The `obj.method()` branch derives the same fact from whether `objExpr`
is a bare name resolving to that class.

`Factory.new.run` keeps the behaviour this PR introduced (Factory#run), which
is itself a fix over the base build's Product#run.

KNOWN LIMITATION, now documented on the contract field and asserted by a test
so a future change to it is deliberate: a class-level override
(`def self.new` returning another type) is still read as construction. The
scope model records no staticness per member, so `def new` and `def self.new`
are indistinguishable at this layer; separating them needs the language
provider to record staticness first. An earlier attempt to use
`TypeRef.source` as a proxy was abandoned after tracing showed Ruby records
body-inferred return types as `return-annotation` too, so it does not
discriminate.

Tests: `ruby-construction-selector` fixture pins all three shapes — class
constant, instance receiver, and the documented class-level-override
limitation. Ruby resolver suites: 185 passed.

* fix(resolution): resolve generic construction receivers (#2708)

`new Box<string>().unwrap()` reached the class lookup as `Box<string>`, which
names no class binding, so the member edge was still dropped while the
non-generic spelling resolved. `new Foo<T>()` is ordinary in all three
keyword-wired languages, so the fix covered a materially narrower slice of
real code than intended.

Retry the lookup on the base name via `stripTemplateArguments` — the same
normalization `resolveClassBindingForName` already applies to typed receivers
in the sibling `receiver-bound-calls` pass. The exact-name lookup still runs
first, so a class whose name legitimately contains `<` is unaffected.

Measured on the probe that first showed the gap:

  before: | viaGeneric | Class:src/box.ts:Box |            (construction edge only)
  after:  | viaGeneric | Method:src/box.ts:Box.get#0 |     (member edge resolved)

Tests: `viaGenericCtor` added to the typescript-inline-constructor-receiver
fixture, asserting both the target file and that the resolved id is `Box`.

* fix(resolution): resolve construction in the chain-head position (#2708)

`new Service(db).inner.deep()` emitted only the construction edge. The chain
walker seeds its starting class from the head segment, which arrives as
`new Service(db)` and reduces via `stripCallParens` to `new Service` — no
binding and no class of that name, so the walk was never seeded and every
segment after it resolved to nothing.

Seed the head through the same construction rule the call branch already uses.
A constructed value is an instance, so the class-constant flag from the
previous commit correctly stays false — `new Factory().new` does not get the
selector treatment.

The gap was asymmetric across the languages this PR wires: Python's bare form
strips to a plain `Service` and was already seeded, so only the keyword
languages were affected.

Tests: `viaChainHead` added to the typescript-inline-constructor-receiver
fixture. Note the fixture annotates `readonly inner: Inner` explicitly —
with an unannotated initializer the walk stops at the field, which is
field-type inference and a separate concern from head seeding.

* fix(resolution): match the construction keyword by token, not by one space (#2708)

The keyword form was matched with `startsWith(`${keyword} `)`, so only a
single space separated `new` from the type. Any other trivia the source used
— a tab, a line break — failed the match and the member-call edge was lost.

Match the keyword as a whole token followed by one or more whitespace
characters instead. `newService()` still fails the match, which is the point:
it is an ordinary call, not a construction, and must keep resolving through
its own return type.

The keyword is escaped before it enters the pattern. It comes from a language
provider rather than from user input, but a keyword containing a regex
metacharacter would otherwise build a silently wrong pattern.

Tests: tab-separated and newline-separated `new` added to the
typescript-inline-constructor-receiver fixture. Note these cases only survive
because `gitnexus/test/fixtures/` is listed in the repo-root `.prettierignore`
— running prettier from inside `gitnexus/` does not pick that file up and
normalizes the tab away.

* fix(resolution): resolve qualified construction callees (#2708)

`new ns.Service().doWork()` emitted only the construction edge. The call
branch splits the callee at its last `.` before construction is considered,
so a qualified type name was routed into `obj.method()` resolution as if
`ns` were a receiver and `Service` a member.

A keyword-marked expression is never a member call, so resolve it as
construction before the split. The callee lookup now also handles a dotted
name: an unambiguous `qualifiedNames` match first, then the trailing simple
name, mirroring how receiver resolution elsewhere in this pass degrades.

Measured:

  before: | viaQualified | Class:src/svc.ts:Service |            (construction only)
  after:  | viaQualified | Method:src/svc.ts:Service.doWork#0 |

Bare-form qualified construction (Python `models.User(db).save()`) is NOT
addressed here: that shape currently emits no edges at all, including no
construction edge, so it is a namespace-import resolution gap upstream of
this pass rather than a construction-typing one.

Tests: `viaQualifiedCtor` added to the typescript-inline-constructor-receiver
fixture.

* fix(java): drop the unreachable constructionSyntax declaration (#2708)

Java was wired `{ keyword: 'new' }`, and the PR described it as one of the
languages that needed the fix. Measuring both ways shows it never did: Java
resolves `new Svc().doWork()` identically with and without the change,
because `java/captures.ts` (#2564) already rewrites an
`object_creation_expression` receiver to the constructed type's simple name,
so the raw `new Svc()` text never reaches this resolver.

The decisive evidence is generics: Java resolves `new Box<User>().doWork()`,
which the keyword path could not do before the template-argument fix earlier
in this series — the resolution demonstrably comes from the capture rewrite,
not from here.

Removing the declaration rather than leaving it as defensive configuration:
an unreachable per-language opt-in reads as coverage that does not exist, and
the contract now records why Java is excluded so the omission is not mistaken
for an oversight.

Verified after removal: the Java probe still resolves both the inline and
two-step spellings, and the Java resolver suites pass (252 passed, 1 skipped).

An earlier coordinator measurement in this review claimed Java WAS broken on
base; that comparison was invalid (the "without fix" build had not been
rebuilt). Corrected here.

* refactor(resolution): state the selector rule once and derive its option type (#2708)

Two follow-ups from review, no behaviour change (643 resolver tests pass
unchanged before and after):

The `Class.new` selector rule was written out twice — in the `obj.method()`
branch and again in the chain walker — against differently named locals,
while the construction helper's own doc comment claimed the rule was stated
in exactly one place. Both sites ask the identical question, so they now call
one `isConstructionSelectorHop` predicate, and the doc comment says what is
actually true.

`ResolveCompoundReceiverOptions.constructionSyntax` re-declared the contract's
object shape by hand. It was the file's first object-shaped duplicate, and
because the value arrives as a non-literal variable, TypeScript's excess
property check would not fire: a sub-field added to the contract later would
type-check and then be silently ignored here. It is now derived with
`ScopeResolver['constructionSyntax']`.

* test(resolution): cover the C# construction path and pin the wiring inventory (#2708)

Three coverage gaps from review, no behaviour change.

C# had no fixture despite being the only keyword-wired language whose
behaviour genuinely depends on the construction rule — measured absent on base
and present on head. `csharp-inline-constructor-receiver` covers the inline
spelling, the two-step spelling, and a static factory that must keep resolving
through its return type rather than being read as construction.

The TypeScript two-step assertion checked only `toContain('Service')`, and the
same fixture defines `LegacyService` — `'LegacyService'.includes('Service')` is
true, so the assertion could not distinguish the two targets. It now pins
`targetFilePath` the way its sibling assertions already do.

Nothing guarded the deliberate opt-in set, so an accidental wiring of a
language that already resolves the shape, or a silent loss of one that needs
it, would pass the whole suite. `construction-syntax-wiring.test.ts` pins the
inventory in both directions: exactly which languages declare
`constructionSyntax` and with which spelling, and that java/php/swift/dart/
kotlin stay unwired.

* chore(storage): bump INCREMENTAL_SCHEMA_VERSION to 23 for the #2708 edge changes

This series changes which CALLS edges are emitted for source whose CONTENT has
not changed — inline constructor receivers that previously emitted nothing now
resolve, and the Ruby selector fix moves one edge back to the member it always
belonged to. That is precisely the class of change the version-history block in
this file requires a bump for, and the reuse gate is a strict equality on the
persisted stamp.

Without it, every existing v22 index passes the gate on the next `analyze` —
or is served by the same-commit "already up to date" fast path — and keeps
returning the pre-fix graph for unchanged files. `impact(direction: "upstream")`
and `context()` would go on omitting the very callers #2708 is about, with no
warning, until something unrelated forced a full re-analyze. The fix would
have shipped without reaching anyone who already had an index.

Precedent is unbroken across the recent resolution PRs: #2723 → v22,
#2699 → v21, #2695 → v20, #2563 → v14, each with its own rationale paragraph.
This adds v23 in the same form.

The pinned assertion in call-summary-schema-version.test.ts moves with it, as
that test documents it is designed to.

* chore(bench): re-baseline the fixture-corpus fingerprints for #2708

Both bench harnesses fingerprint an entire fixture corpus by directory prefix
(`bench/python-scope/measure.mjs:38`, `bench/scope-capture/measure.mjs:76`), so
every fixture directory this series adds moves a committed baseline. Neither
script writes the baseline itself — running without `--check` only prints, and
the file is edited deliberately, which is what its own comment asks for.

Regenerated, last in the series so the fixture set was final:

  bench/python-scope/baseline-fingerprint.txt   36e29abc… -> f120df92…
  bench/scope-capture/baselines.json  ruby       070e4e11… -> fea3edf8…
                                      typescript 281e9548… -> cad25be9…
                                      csharp     e05dc274… -> 05a85bae…

CI only ever reported the python drift, because the benchmarks job runs the
python step first and aborts there; the cross-language step never ran. Both
were verified locally after the update:

  [measure --check] PASS (capture fingerprint + scaling)
  [import-target-fingerprint --check] PASS (resolver fingerprint)
  [scope-capture --check] PASS (15 languages)

The `csharp` and `ruby` entries moved because of the fixtures added earlier in
this series, not the original ones — a reminder that this baseline moves with
any fixture addition, not just the one that first triggered it.

Captures goldens regenerated alongside (csharp, ruby); both additive only, no
existing digest changed. The python golden did not move: no `python-*` fixture
was added after its last regeneration.

fix(rust): resolve module-qualified calls against the module tree (#2730) (#2741)
* fix(rust): resolve module-qualified calls against the module tree (#2730)

A Rust call written with a path (`tools::dispatch(..)`) was captured with only
its tail identifier, making it indistinguishable from a bare `dispatch(..)`.
The scope-chain walk then resolved the bare name lexically and bound it to
whatever `dispatch` was nearest — which, for the common wrapper idiom

    fn dispatch(..) -> ToolOutcome { tools::dispatch(..) }

is the wrapper itself. The graph gained a self-loop, the real cross-module edge
never existed, and `impact` reported the callee as unreached: the issue's
repository showed its central tool dispatcher as `risk: LOW` with 0 affected
processes and both "callers" being `#[cfg(test)]` functions, while still
labelling the result `epistemic: "exact"`.

Resolve paths the way rustc does, over the module tree rather than the
filesystem:

  - `mod_item` now emits `@declaration.namespace`, so a Rust module is a named
    definition rather than an anonymous scope region. This mirrors the existing
    C++ `namespace_definition` capture and lets the shared `tagNamespacePrefixes`
    pass stamp members with their enclosing module path — that pass needed no
    changes to start working for Rust.
  - `module-path.ts` reconstructs the other half of the tree: crate roots are
    directories holding `main.rs`/`lib.rs`, and a file's module path is its
    location below that root. A definition's module is its file's module plus
    any enclosing `mod` blocks.
  - `crate::`, `self::` and `super::` are prefix transforms on the calling
    module, not reasons to stop resolving.
  - The final path segment is looked up as a member of the resolved module,
    including members it only re-exports. A `pub use` creates no binding on the
    re-exporting module's own scope, so re-exports are followed through that
    module's import edges.

Resolution runs ahead of the implicit-`this` and scope-chain tiers, so an
explicit path outranks a lexical shadow, and returns undefined on an unknown
module, a missing member or a tie — leaving the existing chain untouched. The
new `ScopeResolver.resolveQualifiedFreeCall` hook is optional and unset for
every other language, so this is additive.

Fixes the reported case (direct callers 2 -> 3, impacted 2 -> 6, the Agent
module now visible) plus multi-segment paths, `super::` paths and `pub use`
facades, each of which previously produced a wrong edge.

Known limitation, pre-existing and unchanged by this commit: an inline
`mod inner { fn dispatch }` and a crate-root `fn dispatch` in the same file
collapse to one graph node, because node identity is `<file>:<qualifiedName>`
and does not carry the module path. That is a separate defect requiring
module-path-qualified node ids and an incremental-schema migration.

* test(rust): rebaseline the scope-capture fingerprint for the module-tree captures

`mod_item` now emits `@declaration.namespace` and scoped call sites carry
`@reference.qualified-name`. Both are additive, so every bench fixture holding a
`mod` block or a `Foo::bar()` call gains capture groups, and the corpus grew by
the three `rust-2730-*` fixtures.

Only the Rust fingerprint moves. The other 14 languages are byte-identical,
which is the intended blast radius for a language-local capture change.
Scaling stays linear at 1.043, well inside the 1.5 budget.

* fix(rust): carry crate identity in qualified module paths (#2741 review H1)

A module was identified by its path segments below a crate root, so
`crates/alpha/src/tools.rs` and `crates/beta/src/tools.rs` were the same module.
A cargo workspace routinely gives several members the same internal module name
— `util`, `error`, `config`, `types` are near-universal — and that made
qualified resolution do one of two wrong things:

  - where only one member defined the called name, the call bound ACROSS crates;
  - where both defined it, the lookup saw two candidates, refused, and handed the
    site back to the lexical walk that emits the same-name self-loop. The fix for
    #2730 therefore switched itself off in exactly the workspace layouts it was
    written for, and #2730's own reported reproduction repository is multi-crate.

A module is now `{ crateRoot, segments }` and `sameModule` compares both. Rust
has no implicit cross-crate paths — reaching another crate requires naming it —
so two modules in different crates are never the same module. Anchored paths
(`crate::`, `self::`, `super::`) resolve inside the caller's own crate and
inherit its root.

Covered by a two-member workspace fixture where both crates define
`tools::dispatch` behind a same-name wrapper, plus unit tests for the path
arithmetic itself, including the branches no fixture reaches (a file under no
crate root, a `super::` chain walking above the crate root).

* fix(rust): count only module members when resolving a qualified call (#2741 review H3)

Module membership was inferred from the file path alone, so any callable in the
right file counted as a member of the module. A `fn` nested inside another `fn`
has the same `filePath`, the same bare `qualifiedName` and no owner, making it
indistinguishable from a module-level item:

    pub fn dispatch() -> usize { 3 }              // the real member
    pub fn wrapper() -> usize {
        fn dispatch() -> usize { 99 }             // counted as a second member
        dispatch()
    }

Two candidates tie, the lookup refuses, and the call falls back to the lexical
walk that emits the same-name self-loop — so an unrelated local helper anywhere
in a module silently reinstated #2730 for every qualified call into it.

The scope model already draws the line exactly: a module-level item is bound
with `origin: 'local'` in its module's own scope, a function-local item binds in
the enclosing Block, and an `impl`/trait method binds in the Class scope.
Membership is now that binding lookup rather than a path comparison.

Inline-`mod` members bind in their Namespace scope rather than the file's Module
scope, and reaching it would mean walking every child scope — faulting them back
in from disk on the out-of-core path. They keep being identified by the
`namespacePrefix` the shared tagging pass stamps on them, which a file-module
member never carries. The documented residual is a `fn` nested inside a `fn`
inside an inline `mod`, which inherits that prefix; that is strictly smaller than
before and costs a refusal, never a wrong edge.

* fix(rust): require a use-binding to name a module, not a type (#2741 review H2)

Import resolution deliberately strips a trailing symbol segment when probing for
a file — "the last segment might be a symbol (function, struct, etc.), not a
module. Strip it and try again" (import-resolvers/rust.ts). So
`use crate::client::ClientBuilder;` also resolves to `client/mod.rs`.

The qualified-call resolver took that at face value and treated the imported
TYPE as the module `client`. Rust impl methods carry a bare `qualifiedName`, so
`ClientBuilder::new()` was then looked up among `client`'s module members and
bound to an unrelated module-level `new` — turning an unresolved site into a
false edge, which the module's own contract calls the worse outcome.

A binding now has to name the module it resolved to. The edge's
`targetExportedName` is the tail of the written path, so comparing it against the
resolved module's own tail separates the cases exactly:

    use crate::tools;                 tail `tools`         module ['tools']    accept
    use crate:🅰️:b as tools;         tail `b`             module ['a','b']    accept
    use crate::tools::{self, Ctx};    tail `tools`         module ['tools']    accept
    use crate::client::ClientBuilder; tail `ClientBuilder` module ['client']   reject

Covered by a fixture where `client/mod.rs` deliberately holds both
`impl ClientBuilder { fn new }` and a module-level `fn new`, so a regression
re-binds to the wrong one, plus a control asserting a genuine `client::new()`
module qualifier still resolves.

* fix(rust): give src/bin targets their own crate root (#2741 review)

Cargo auto-discovers a binary target for every `src/bin/<name>.rs`. Each is a
separate crate with its own `crate::` root, and its submodules live under
`src/bin/<name>/`.

Only `main.rs` and `lib.rs` established a crate root, so those entry files were
folded into the surrounding library and given the invented module path
`bin::<name>`. That made `crate::helper()` inside a binary resolve into the
LIBRARY's `helper` — and unlike the other findings in this review, this one
downgraded an edge the lexical walk had previously resolved correctly, so it
made existing output worse rather than merely failing to improve it.

`src/bin/<name>.rs` is now its own crate root (as is the `src/bin/<name>/main.rs`
directory form), so a binary's modules and the library's modules of the same name
are no longer the same module.

* fix(rust): only try a submodule candidate the caller actually declares (#2741 review)

The first candidate module was `callerModule ++ qualifier`, yielded before the
`use` channel and never checked against anything. That let file layout outrank a
real import: with `use crate::b;` in `src/a/mod.rs` and an undeclared — or
`cfg`-gated — `src/a/b.rs` present on disk, `b::f()` bound to the sibling file,
where rustc resolves it to `crate::b`.

A `mod` declaration, inline or file-backed, emits a `Namespace` def bound locally
in the declaring scope, so the candidate is now gated on that binding rather than
assumed. When the caller does not declare the submodule the candidate is skipped
and the `use` and crate-root channels still run, so this only removes guesses.

* fix(rust): follow only real re-exports, and refuse on an ambiguous one (#2741 review)

Two problems in the re-export channel.

A private `use` was followed as though it re-exported. `use crate::tools::helper;`
makes `helper` visible INSIDE the module; it does not put it on the module's
public surface, so `facade::helper()` does not compile. Only `pub use` does, and
finalize already distinguishes them — `reexport` for `pub use`, `named` for a
private one. The `alias` kind is now accepted alongside `reexport`, because
`pub use x::y as name` is a re-export that was previously ignored entirely.

The lookup also took the first matching edge in file-iteration order, which is
parse-pool order. Two `cfg`-exclusive facades re-exporting the same name are
indistinguishable at this layer, so picking one baked a coin flip into the graph.
It now refuses on a genuine tie, consistent with how member lookup already
behaves.

The pre-existing limitation that only FILE modules are reachable — a `pub use`
inside an inline `mod facade { … }` has no `moduleScopeByFile` entry — is now
stated in the code. Reaching those would mean walking every child scope and
faulting the scope tree back in from disk, which is the cost that index exists to
avoid; a miss falls through to the unchanged chain rather than guessing.

The regression test deliberately makes the re-exported name globally ambiguous.
Without that, the pre-existing unique-global free-call fallback resolves the call
on its own and the assertion passes whatever this channel does.

* perf(rust): stop type-qualified calls paying for module resolution (#2741 review)

The capture carrying `rawQualifiedName` matches every `scoped_identifier`
callee, so this hook was reached by `Vec::new()`, `String::from()`,
`Self::method()` and every other type-qualified call — the overwhelming majority
of `::` calls in real Rust, none of which name a module. Each one ran the full
candidate search before returning undefined, and every candidate that missed then
walked all of `workspaceIndex.moduleScopeByFile`. Total cost grew as
`qualified-call-sites x files`; two independent measurements put per-site cost at
0.117 -> 0.428 ms across 301 -> 1201 files, i.e. linear in workspace size.

Two changes:

  - The module index now carries a flat set of every module segment name in the
    workspace, and a qualifier whose head matches none of them is rejected before
    any candidate work. Measured at 0.02 us per rejected call and flat in file
    count (500 -> 8000 files), against a previously linear per-site cost.

  - Module scopes are indexed by module identity once per pass rather than
    rediscovered by scanning every file per candidate. On the out-of-core scope
    index that scan was worse than CPU: `moduleScopeByFile` fetches through
    `scopeTree.getScope`, so a full sweep could fault every module scope back in
    from disk — the pattern `workspace-index.ts` added `exportedCallableByName`
    to avoid. Given the #2649 and #1871 history this mattered before merge.

The captures golden is regenerated for the fixture files added earlier in this
series; `emitRustScopeCaptures` itself is unchanged by this commit.

* fix(storage): bump schema versions so the #2730 fix reaches existing indexes

Neither invalidation constant was bumped, so the fix did not reach the users who
reported the bug.

`INCREMENTAL_SCHEMA_VERSION` 22 -> 23. The incremental write set only covers
CHANGED files, so a top-up against a pre-v23 index keeps the wrong self-loop —
and keeps reporting the callee as unreached — for every unchanged Rust file. The
constant's own doc block states this rule, and the precedent is exact: v11 is the
same file (`rust/query.ts`) gaining a capture that changes CALLS edges, with the
same "force a full re-analyze" contract, and v12 is a second Rust instance.

`SCHEMA_BUMP` 30 -> 31. `@declaration.namespace` and `@reference.qualified-name`
are parse-time captures, so a warm parse cache replays the old capture set
verbatim: `rawQualifiedName` comes back undefined and no Namespace def exists to
hang a module prefix on, turning the entire resolution tier into a no-op on
unchanged files. `PARSE_CACHE_VERSION` folds in the package version, so a tagged
release would have invalidated eventually — but source, dev and CI builds at the
same version would not, and the v29 note already warns that relying on someone
else's bump is how a change ships with no invalidation at all. Re-checked against
origin/main at commit time, as that note instructs.

* fix(scope-resolution): let a language opt out of the already-namespaced guard (#2741 review)

`tagNamespacePrefixes` skips a def whose `qualifiedName` already equals, or is
prefixed by, its enclosing namespace path. That is right for C++ and C#, where
the qualified name genuinely carries the namespace.

Rust qualified names never do, so the guard fired on a coincidence: in
`mod a { pub fn a() }` the member's name equals its module's name, the prefix was
skipped, and `moduleOfDef` then reported the member as belonging to the PARENT
module. `crate:🅰️:a()` refused, and the def became indistinguishable from a
crate-root `fn a` for the module matcher.

The guard is now conditional on a `qualifiedNamesCarryNamespace` option that
defaults to the existing behaviour, and Rust opts out. The shared pass stays
language-neutral — the decision lives with the provider that knows what its own
qualified names contain.

C++ and C# resolver suites pass unchanged alongside the Rust ones (600 tests).

* fix(rust): refuse a leading :: path instead of reading it as relative (#2741 review)

A leading `::` anchors at the extern prelude: `::tools::dispatch()` names the
CRATE `tools`, not a module of the current one. The path split filtered the empty
leading segment away, which silently reinterpreted the path as relative and let
it resolve against a local module that happens to share the name.

Extern crates are outside the workspace module tree, so the qualified tier now
refuses and leaves the site to the unchanged chain.

The regression test asserts the tier does not bind into the local `tools` module,
rather than asserting no edge at all: the lexical tier still resolves the bare
tail on its own, and that behaviour is not what this change governs. Asserting an
empty edge list would have been testing a different tier.

* refactor(rust): reuse the canonical callable predicate and drop dead re-exports (#2741 review)

`CALLABLE_TYPES` was a local copy of the set behind `isOverloadableCallable` in
`utils/callable-labels.ts`. Two copies of the same set drift: extending the
canonical one with a new callable kind would silently leave qualified calls of
that kind unresolved here, with nothing to catch it. Use the shared predicate.

The trailing `export { moduleOfFile, moduleOfDef }` and
`export type { ScopeResolutionIndexes }` were commented as being "for the
resolver's unit tests". No test imports them: the only importer of this module
anywhere in src or test is `rust/scope-resolver.ts`, which takes just
`resolveRustQualifiedFreeCall`. Both functions are already exported from
`module-path.ts` (where the new unit tests take them from), and
`ScopeResolutionIndexes` is canonically exported from
`model/scope-resolution-indexes.ts`. Removed rather than left as surface that
implies a contract it does not have.

* test(rust): rebaseline the scope-capture fingerprint with the correct prior hash

The rebaseline note added with the original fix cited
`Prior 655aed01…`, which was two rebaselines stale — it predates both #2604 and
#2714. The true pre-PR value on the base commit is `7f1240b3…`. CI could not
catch it: the gate compares the live fingerprint against the stored one and never
reads the prose, so the audit chain these notes exist to provide was broken with
nothing to flag it.

The note now carries the correct prior value, and the fingerprint is regenerated
for the fixtures this review series added. Scaling 1.061, well inside the 1.5
budget; fixture_count 196; the other 14 languages remain byte-identical.

* test: move the schema-version pin to 23

`call-summary-schema-version.test.ts` asserts the exact value of
`INCREMENTAL_SCHEMA_VERSION` and enumerates which stamped versions the
incremental reuse gate accepts. It moves with every bump by design — that pin is
what stops an id- or edge-changing commit shipping without invalidation.

Updated for the bump to 23, with the pre-v23 case added to the reuse-gate table:
a v22 index predates Rust module-qualified call resolution, so every unchanged
Rust file would keep the same-name self-loop and keep reporting the real callee
as unreached.

Caught by CI rather than locally, because the earlier sweeps in this series
covered `test/integration/resolvers/` and `test/unit/scope-resolution/` only —
the pin lives outside both.

fix(scope-resolution): resolve calls through a closure-valued binding across languages (#2693) (#2695)
* fix(scope-resolution): resolve calls through a closure-valued binding (#2693)

`val f = { }; f()` emitted no CALLS edge in Kotlin or Swift, so `impact` on
such a symbol under-reported to zero — the same false all-clear as #2687.

The cause was not, as first suspected, that these languages fail to feed
`callable-value-flow`. They do: `synthesizeCallableFlowCaptures` is called
from 15 language capture modules, and Kotlin already resolves reassignment
through the pass (`var f = ::a; if (c) f = ::b; f(1)` reaches both targets).
Their captures are already exactly right — the seed names the binding as its
own callable, per the anonymous-callable convention in
callable-flow-captures.ts.

They died one layer later, at the `buildGraphTargetIndex` gate:

    if (!isCallable(def) && providerTarget?.(def) !== true) continue;

`isCallable` is Function/Method/Constructor, but the scope-resolution layer
declares a closure binding with its VALUE label (Kotlin/Swift `Property`),
and `isCallableValueTarget` is implemented by exactly one provider — COBOL.
So the binding never entered `graphTargets`; `lexicalCallableLookup` then
returned `shadowed: true` with no targets, which also suppressed the
workspace-wide fallback, and the seed resolved to nothing.

Only the graph knows a value binding holds a callable — since #2687 it emits
a single `Function` node for one. So value bindings now resolve their graph
id first and are admitted on the label of the node they actually reach.

This is self-limiting: a genuine constant keeps its own Const/Property node,
so `resolveDefGraphId`'s qualified key hits before the label-agnostic
`simpleKey` fallback can reach a same-named callable. Only a binding whose
own value node was replaced by a callable one gets through.

No scope kind changes — Kotlin's `lambda_literal` stays `@scope.block`, so
#1757 smart-cast semantics are untouched by construction. The fix is
language-neutral: it discriminates on the graph node label, never on a
language name.

Dart is fixed separately; its root cause is independent.

* fix(dart): resolve calls through a closure-valued binding (#2693)

Dart needed more than the shared gate fix: neither of its closure-binding
forms could resolve, for two different reasons, and the plan's one-line
diagnosis turned out to be incomplete.

TOP-LEVEL `var f = (x) => x;`
  A graph Function node already existed (#2687), but no `@declaration.*`
  matched the binding, so scope resolution had no SymbolDefinition to attach
  a flow seed to. Adding the declaration exposed a second problem: Dart's
  `initialized_identifier` is FIELDLESS, so the shared field-based assignment
  fallback (`left`/`name`/`value`/…) decomposed nothing and the binding still
  emitted no flow captures at all. Kotlin's fieldless `assignment` node hit
  exactly this and took the same remedy — a provider `extractAssignment`.

FUNCTION-LOCAL `void m() { var f = (x) => x; }`
  Locals parse as `initialized_variable_definition`, which the top-level
  graph-node rules are deliberately anchored under (program) to avoid, so a
  local closure had no graph node at all — nothing for the widened
  `buildGraphTargetIndex` gate to admit.

Both new rules are restricted to a `function_expression` value. Declaring
every Dart variable would mint defs and nodes repo-wide for no resolution
benefit; ordinary locals stay unindexed exactly as before. The top-level
declaration reuses the (program) anchor the graph-node query already relies
on, so class-body fields — which share `initialized_identifier_list` and are
already `@declaration.property` — are never matched twice.

Also drops the now-false note in tree-sitter-queries.ts claiming `f()` does
not resolve for Dart. That node is now the evidence that makes it resolve.

* docs(scope-resolution): document the callable-flow capture contract (#2693)

The module is 1200+ lines behind a nine-line docblock, and the only worked
example was C. Both root causes fixed in this series were "the contract was
discoverable only by reading the emitter":

  - the anonymous-callable convention (a seed whose source is a closure takes
    its DESTINATION's name) is what makes closure bindings resolvable at all,
    and is the reason the widened target gate is correct;
  - a fieldless binding node silently decomposes to nothing under the shared
    assignment fallback, which cost Kotlin one debugging cycle in #2522 and
    Dart another here;
  - captures alone are never enough — the bound name also needs a
    `@declaration.*` or there is no cell to key the seed on.

Records the cell/site model, both traps, and points at the fullest and
smallest worked examples.

Bumps INCREMENTAL_SCHEMA_VERSION 15 → 16 and the parse-cache SCHEMA_BUMP
22 → 23: this series emits NEW CALLS edges and new Dart Function nodes, and
the incremental write set only covers changed files, so an existing index
would keep reporting a zero blast radius for exactly the symbols the fix is
about.

* perf(scope-resolution): pre-filter value bindings in the callable target index (#2693)

Widening the `buildGraphTargetIndex` gate to consider VALUE bindings put the
hot loop on a much larger def population — value bindings outnumber callables
in real source — and the naive version paid full price per binding. Measured
on a synthetic 800-file corpus (8 value bindings per file, 1 of them a closure
binding), the widening cost 2.50-2.82x the pre-#2693 callable-only build.

Two wastes, both provable rather than guessed:

1. `definitionAnchorKey` ran for every def, including value bindings. The
   anchor index is keyed by callable LABEL and the key is built from
   `def.type`, so a value def can never hit it — and the key costs a regex
   per def.

2. Every value binding paid the whole `resolveDefGraphId` key chain only to be
   rejected. It need not: every qualified key that function tries embeds
   `def.type`, so for a VALUE def those can only ever reach a value-labelled
   node. Its one route to a callable is the label-agnostic
   `simpleKey(filePath, simpleName)` fallback, which by construction requires
   a callable node with the SAME file and simple name. So a value binding with
   no such node cannot resolve to a callable, and one Set lookup decides it.

That set is derived in the graph walk the anchor index already performs, so it
costs no extra pass.

  large_ms            7.79-8.37  ->  4.90-5.02   (1.61x faster)
  widening_overhead   2.50-2.82  ->  1.45-1.50

The resolved target-set fingerprint is byte-identical across both, which is
the point: this is a cost change, not a behaviour change.

Adds bench/callable-value-flow/ (fingerprint + scaling + widening-overhead
gates) and wires it into ci-tests.yml beside the other build-free benches. The
overhead budget of 1.9 sits between the measured with-filter and without-filter
bands, so it cannot be met if the pre-filter is removed. Timings use the MIN of
15 warmed reps, not the median: the same build reported 1.65 idle and 2.03
under load, and a median-based gate would have to be loosened past the point of
detecting the regression it exists to catch.

`buildGraphTargetIndex` is exported for the bench; it is pure and not part of
the pass's public contract.

* test(scope-resolution): assert the declaration route does not double-emit (#2693)

Go, Python, C++ and TS/JS already resolved a closure-binding call through
their `@declaration.function` capture. The widened `buildGraphTargetIndex`
gate gives the same call a SECOND possible route, so each must still produce
exactly one edge.

`tryEmitEdge` dedups by key, but a collapsed key and a site-anchored key are
DIFFERENT keys — a real double-emit would show up as two ids for one call
site, not be silently collapsed. Asserting on edge ids rather than target ids
is what makes that visible.

* fix(scope-resolution): join value bindings to their callable node by POSITION (#2693)

Review found the first cut of this series minted FALSE CALLS edges. Admitting a
value binding whose *resolved* graph node is callable let `resolveDefGraphId`
fall through to its label-agnostic, first-write-wins
`simpleKey(filePath, simpleName)` and bind the name to ANY same-named callable
in the file.

The safety argument in the previous commit — "a genuine constant keeps its own
Const/Property node, so the qualified key hits first" — silently assumed
`def.type === node.label`. It does not hold:

  - TypeScript declares `const` as `Variable` but emits a `Const` NODE, so the
    qualified key misses even though the value node exists;
  - Rust `let` bindings get no graph node at all, so the fallback is the only
    route.

Reproduced, all previously emitting a fabricated caller:

  const save = (x: number) => x * 2;   // next to an unrelated Svc.save
      -> Method:svc.ts:Svc.save#1      // Svc never instantiated
  const handler = other;               // shadowing a top-level handler
      -> Function:app.ts:handler       // unreachable from here
  let handler = cb;                    // Rust
      -> Function:main.rs:handler

Worse in Dart, where the same collision INVERTED the feature: the only edge went
to the class method and the closure's own node got none. The result was also
declaration-order dependent — two files differing only in declaration order got
different CALLS sets — and it propagated through argument-to-formal binding into
functions whose source never mentions the name.

A closure binding IS its callable node: same file, same line, same name. An
aliasing local is not. So the join is positional now — a file/line/name index
built in the graph walk `byAnchor` already performs — and value bindings never
run the key chain at all. That is both correct and cheaper:

  large_ms            4.90-5.02  ->  4.37-4.63
  widening_overhead   1.45-1.50  ->  1.43-1.58   (name-match design: 2.50-2.82)

with a byte-identical target-set fingerprint on the bench corpus.

Also from review:

  - `Static` dropped from VALUE_BINDING_DEF_TYPES: `normalizeNodeLabel` has no
    `static` case, so no def can carry that type — it was an entry no fixture
    could ever exercise. The remaining set now documents why it deliberately
    does NOT reuse `isOwnableValueLabel`, which is contracted to a different
    consumer.
  - Dart `final`/`const` top-level closures (static_final_declaration_list) and
    every declarator after the first in a multi-name local now resolve; both
    parse into shapes the earlier rules never reached.
  - The bench source carried a literal NUL byte, so git recorded it as BINARY
    and the only artifact pinning the target set was unreviewable in the PR
    diff. It is written as an escape now. Its corpus also modelled `startLine`
    as 1-based where graph nodes are 0-based, which would have stopped it
    exercising the value-binding path at all.
  - `call-summary-schema-version.test.ts` asserted `passesReuseGate(15)` is
    true; the 15 to 16 bump made that false and the test RED. It now pins 16 as
    current and 15 as rejected, matching the pattern every prior bump followed.
  - The v23 parse-cache comment is at the top of the list, not mid-list.

Tests: the five collision cases above are new regression tests, each confirmed
failing against the previous commit. Also added Kotlin class-body closures (the
only case exercising the Method arm), Dart top-level `final`, Dart multi-name
locals, and a warm-parse-cache replay for Kotlin and Dart — the #2693 captures
are replayed verbatim, so a serialization change would surface only on a SECOND
analyze and every other test here runs cold. The previous negative tests were
vacuous: they paired names that did not collide (`maxSize` vs `size`), so the
pre-filter rejected them before the guard they were named after could run.

* docs(storage): fix the schema-version changelog blocks (#2693)

Two problems, one mine and one not.

MINE: the `INCREMENTAL_SCHEMA_VERSION` block is ASCENDING (v2 … v15), and I
inserted v16 above v15 rather than at the end — I had just moved the parse-cache
entry to the top of ITS block, which is descending, and applied the same habit
to a list ordered the other way. Moved to the end; both blocks are now
internally consistent.

NOT MINE: the parse-cache block carries TWO v21 entries, with v20 wedged between
them. Tracing it: #2632 (Spring DI facts) bumped 20 -> 21 and merged first;
#2653 (Java JLS local-class identities) had branched at 20, also bumped to 21,
and merged second — so it shipped with NO invalidation of its own. An index
already stamped 21 by the first change was treated as current by the second and
kept serving stale local-class identities from the warm cache.

Numbers left alone: both genuinely shipped as 21, and renumbering them now would
misstate what users' indexes actually contain. Instead the entry says so
explicitly, and points at the process fix — re-check the constant against
origin/main immediately before merging, not just when the branch is cut. The
identical collision hit INCREMENTAL_SCHEMA_VERSION in #2653/#2654, so this is a
recurring failure mode of concurrent PRs, not a one-off typo.

Comment-only; no constant changes value.

* feat(scope-resolution): resolve closure bindings in Ruby, Java, C#, PHP and JS/TS var (#2693)

Ruby, Java, C# and PHP already emitted correct callable-flow seeds and invokes.
What they lacked was the #2687 piece — a CALLABLE graph node at the binding,
which is what buildGraphTargetIndex joins to by position. PHP additionally had
no scope declaration for the bound name, so the flow pass had nothing to attach
its seed to.

  ruby    handler = ->(x) { x }        handler.call(1)   -> Function:a.rb:handler
  java    Function<..> handler = x->x  handler.apply(1)  -> Function:A.java:A.handler
  csharp  Func<int,int> handler = ...  handler(1)        -> Function:A.cs:A.handler
  php     $handler = fn($x) => $x      $handler(1)       -> Function:a.php:handler

Ruby and Java invoke through the callable-object protocol; C# and PHP call the
binding directly. Locals work in all four, and a binding whose name collides
with a same-named method resolves to the CLOSURE, not the method.

Two things the sweep caught:

JAVA TWIN. Anchoring the rule on the inner variable_declarator produced BOTH a
Function and a Property node — the exact double-indexing #2687 removed. The
parse-worker dedup keys on (definition node, name), and Java's value rule
anchors on field_declaration, so the keys never matched. Re-anchored on
field_declaration / local_variable_declaration.

JS/TS `var`. `var f = (x) => x` kept a Variable label while const/let got
Function, because `var` is a different grammar node (variable_declaration vs
lexical_declaration) that no closure rule covered. A call through the binding
still resolved via the declaration route, so the CALLS edge pointed at a
NON-callable node. Now consistent across const/let/var.

That last one flipped an existing assertion in const-function-twin.test.ts,
which expected `Variable` for a var-bound function-expression. Its comment
explained why — "var has no matching @definition.function pattern, so nothing
claims the name" — i.e. it documented the gap rather than defending it. The
property it was really protecting (an UNCLAIMED value node survives) now has
its own case with a non-function initializer, and the var-closure case asserts
the collapse to one node, which is also the twin guard for the new rule.

Known limits, both pre-existing and both failing safe:

  - A PHP local closure whose name collides with a top-level function gets no
    edge: both want id Function:<file>:<name>, so the closure never gets its own
    node. This is the file-scoped node-identity convention — TypeScript, Python
    and Dart collapse identically at base.
  - TS/JS class-field arrows stay Property (Kotlin's equivalent emits Method).
    They already resolve; changing the label risks the HAS_PROPERTY ownership
    regression #2687 hit once.

The invalidation constants already bumped in this PR (INCREMENTAL_SCHEMA_VERSION
16, SCHEMA_BUMP 23) cover these additional languages; their notes now say so.

Tests: one case per newly-resolving language plus the PHP anonymous-function
form and the JS var form, in closure-binding-labels.test.ts. The file now spins
a worker pool per test across a dozen languages, so its timeout is raised
file-wide — a case that takes ~7s alone was exceeding the 30s default under
that contention.

* fix(ingestion): class-field closures are callable members in TS/JS (#2693)

A CALLS edge must target a callable node. `class A { handler = (x) => x }` emitted
a Property, so calling it produced `CALLS -> Property:A.ts:A.handler` — an edge
pointing at something the graph says is not callable. Same defect class as the
JS/TS `var` binding fixed in the previous commit, and the last place a closure
binding still carried a value label.

Kotlin already models its class-body closure as Method + HAS_METHOD; TS/JS now
match, so all three agree:

  class-field closure   -> Method   + HAS_METHOD    (CALLS target is callable)
  plain class field     -> Property + HAS_PROPERTY  (unchanged, no CALLS)

Anchored on public_field_definition / field_definition — the same nodes the
property rules use — so the parse-worker dedup collapses the pair rather than
leaving a Method/Property twin, the failure the Java rule hit in the previous
commit.

ON MATCHING THE COMPILERS. This deliberately diverges from tsc and SCIP. The
TypeScript compiler classes `handler = () => {}` as a PropertyDeclaration
("a property declaration independently from what it's assigned to"), and SCIP
gives it a `.` term descriptor, the same suffix as any field — both call it a
property, and Kotlin's compiler likewise treats `val f = { }` as a property with
a function type. The divergence is intentional: GitNexus's Function/Method label
does not mean "tsc SymbolFlags", it means "this node can be the target of a
CALLS edge", which is the convention #2687 set for closure bindings in every
language. Modelling it the compiler's way would mean either dropping call
resolution for these members or emitting a separate node for the lambda and
flowing the property to it — the two-node shape #2687 removed. Recorded here so
the next reader does not "fix" it back.

Tests: TS and JS class-field arrows resolve to their Method node, plus a guard
that a NON-closure class field stays a Property — the closure rule must key on
the initializer, not on the field syntax.

* fix(php): keep the $ sigil on closure-binding nodes so locals stop colliding (#2693)

A PHP local closure whose name matched a file-level function got NO edge at all:

    function save($x) { return $x; }
    function run() {
      $save = fn($x) => $x * 2;
      return $save(1);              // no CALLS edge
    }

Both minted the id Function:<file>:save, so the closure's node was swallowed by
the function's and the positional join found nothing at the binding's line.

The fix is PHP's own semantics rather than a change to node identity across the
graph. PHP holds variables and functions in SEPARATE namespaces — $save and
save() cannot collide in the language — and the sigil is what separates them.
Dropping it was the bug. The node rule now captures the whole variable_name, so
the closure is Function:<file>:$save and the function stays Function:<file>:save.
languages/php/query.ts already keeps the sigil on property declarations for the
same reason, so this makes the two consistent.

The positional join normalises a leading $/@ on both sides, matching what the
scope layer and the callable-flow synthesizer already do, so the binding still
matches its own declaration while its NODE stays distinct.

    local closure + same-named function -> Function:c.php:$save   (the closure)
    calling the real function           -> Function:f.php:save    (unchanged)
    plain $max = 10                     -> no node, no edge       (unchanged)

WHAT THIS DOES NOT FIX. The general problem is wider than PHP: GitNexus node ids
are file-scoped, so a function-local symbol and a file-level one with the same
name collapse in TypeScript, Python and Dart too, and Java/C# only escape by
qualifying on the enclosing CLASS (so two same-named locals in different methods
still collide). SCIP solves it with a separate `local <id>` keyspace that is
document-scoped and never globally addressable. That is issue #2699 — it changes
persisted ids for every function-local symbol and needs its own invalidation, so
it is not bundled here. PHP is fixed on its own merits: the sigil belongs in the
identity regardless of how locals are eventually scoped.

* test(scope-resolution): pin the closure-binding caller-attribution limit (#2693)

Review of this PR found the new callable nodes are call TARGETS but never call
SOURCES: a call made INSIDE a closure binding is attributed to the enclosing
scope, so `impact(handler, direction:"downstream")` reports nothing even though
the closure calls out. Consistent across Kotlin, Dart, Ruby and PHP; TS/JS free
bindings are the exception because their arrow carries a @scope.function whose
range matches.

Not fixed here — pinned, so the boundary is visible instead of surprising, and
so a change in EITHER direction fails a test.

The cause is precise: `pickCallerCallableDef` (graph-bridge/ids.ts) finds the
caller by walking CHILD scopes whose range contains the call site, gated on
`child.kind === 'Function'`. A closure literal is a BLOCK scope in these
languages (Kotlin deliberately, #1757 smart casts), AND the binding's def is
owned by the enclosing scope rather than by the closure's scope — so neither
half of the link exists. Fixing it needs "callable boundary" decoupled from
scope `kind` plus an association between the closure scope and its binding.
That is a change to the caller anchor used by every call in the repo, which is
not something to land at the tail of this PR.

Also adds a unit suite for `buildGraphTargetIndex` itself, covering what the
integration tier cannot isolate: a binding is admitted only on POSITIONAL
evidence, a name-only match is rejected, a non-callable node at that position is
rejected, an ambiguous position claimed by two callables is rejected, and the
PHP dollar sigil normalises across the join while still not matching a
same-named function on another line. That last one closes the review's LOW —
the node/declaration name asymmetry now has an executable contract rather than
resting on a comment.

* docs(test): correct the per-language cause of the attribution limit (#2693)

The comment on the pinned attribution tests claimed "a closure literal is a
BLOCK scope in these languages". That is true for Kotlin (lambda_literal
@scope.block, #1757) and Ruby (do_block/block @scope.block) and FALSE for PHP:
anonymous_function and arrow_function are already @scope.function
(php/query.ts:61-62). Dart is a third case again — it has no scope over a
closure literal at all.

So the four languages fail at three different points, not one:

  Kotlin, Ruby  fail the `child.kind === 'Function'` gate
  PHP           passes that gate; its closure scope owns no callable def,
                because the binding's def belongs to the enclosing scope
  Dart          has no child scope for the walk to consider

Worth correcting carefully rather than tidying: a follow-up plan re-stated this
comment instead of re-deriving it, and inherited the misdiagnosis — it proposed
"relax the kind gate" as required for all four, which is a no-op for PHP and
unreachable for Dart. A review caught it. The comment now states each language's
actual blocker and says why the distinction matters.

Comment-only; the three pinned tests are unchanged and still pass.

* fix(scope-resolution): an ordinary JS/TS `function` binds its own `this` (#2701)

`this.m()` inside a nested `function` resolved to the lexically enclosing
class, so it emitted a CALLS edge that does not exist at runtime — including
the exact `forEach(function () { this.m(); })` shape arrow functions were
introduced to avoid:

    class D {
      m() {}
      build() { const h = function () { this.m(); }; return h; }
    }
    // CALLS: Function:D.ts:D.h -> Method:D.ts:D.m#0      FALSE

ECMA-262 gives an arrow `[[ThisMode]] = lexical`: it has no `this` binding in
its environment record, so the lookup passes through to the enclosing
environment. Every other function form binds `this` at call time. `tsc` draws
the same line by resolving `this` through `getThisContainer` with
`includeArrowFunctions = false`. That one rule is the whole fix.

Languages declare it; shared code never learns a language. The query files —
the one place that already names grammar nodes — tag every non-arrow function
form with `@receiver-owner.this`, which becomes `Scope.ownsReceivers`. A
receiver walk that reaches such a scope without finding the name stops there
instead of borrowing an enclosing scope's binding. Every other language leaves
the field unset and is bit-for-bit unchanged; a Kotlin lambda, which DOES
capture the enclosing `this`, still resolves (pinned as a test).

THREE GATES, ALL LOAD-BEARING. The false edge survived each one alone, which
is why the tests assert on the emitted edge rather than any single walk:

  1. `Scope.ownsReceivers` stops BOTH receiver-type walks — `findReceiver
     TypeBinding` here and its twin `lookupReceiverType` in gitnexus-shared's
     `lookup-core`, which was resolving the receiver independently.
  2. `LanguageTypeConfig.thisBoundaryNodeTypes` stops the type-env AST walk
     that infers a receiver's type during capture.
  3. `isReceiverOwnedButUnbound` makes `receiver-bound-calls` SUPPRESS the
     site. Without it the member still resolved by NAME through `lookupCore`'s
     lexical chain — the class-body scope binds `m` two scopes up — merely at
     lower confidence. An owned-but-unbound receiver is a definitive negative,
     not a miss, so it must not reach a receiver-blind fallback.

Also fixed: `function*(){}` as an expression was not a `@scope.function` at
all, so `this` inside one read as the enclosing method's.

WHAT THIS GIVES UP. The fix REMOVES edges, and some were correct:
`.bind(this)`, `.call(this)` and `forEach(fn, thisArg)` do make `this` the
instance at runtime. Their correctness is fixed at the CALL SITE, which no
scope-level rule can see, so the choice is between losing them and keeping
every detached-callback false positive. All three are pinned as tests
asserting the empty result, so changing the trade later is deliberate.
`this` in a static method also stops resolving to the INSTANCE member — that
edge was wrong in the other direction.

INVALIDATION. Both constants move, and the parse-cache one is not optional:
`ownsReceivers` lives on the cached `Scope`, and a warm cache replays scopes
without it — verified by probe that `--force` alone does NOT re-derive it, so
the fix silently did nothing until SCHEMA_BUMP moved. INCREMENTAL_SCHEMA_
VERSION 16 -> 17 (the incremental write set covers only changed files, so
unchanged TS/JS files would keep their fabricated `this` edges);
SCHEMA_BUMP 23 -> 24.

Verified against a built index, not by reading: all three false edges from the
issue gone, every correct edge kept, same result in JavaScript through its
separate grammar. 64 tests green across the new suite plus the closure-binding
and schema-version suites. The full suite's 36 failures are pre-existing
load-flakes — confirmed by A/B: `skip-git-cli` fails FOUR tests on a clean
HEAD versus three with this change, and `pipeline-pdg-streaming` passes in
isolation either way.

Refs #2701

* fix(ingestion): give function-local callables their own identity (#2699)

Graph node ids were file-scoped, so a local callable and a same-named
file-level one collapsed onto ONE node. That is a wrong answer, not a missing
one — the local call was attributed to the file-level symbol:

    export function save(x) { return x; }
    export function run()   { const save = x => x * 2; return save(1); }
    export function other() { const save = x => x * 3; return save(2); }

    // ONE node Function:a.ts:save, and BOTH run and other pointed at it, so
    // `impact` on the top-level save reported two callers that never call it.

A local's identity is now its enclosing-callable chain plus its own position —
`run.save@2:2`. The chain is for humans reading `impact`; the position is what
makes it correct. Names alone cannot express what ECMAScript actually
specifies, and the gap is the language's, not the grammar's: an environment
record is created per function AND per block, so an anonymous function has no
name to contribute and sibling blocks hold distinct bindings under the same
name. One positional rule settles both, with no conditionals and no
"disambiguate only when it looks ambiguous" heuristic — the ambiguity-flag
class of bug that bit #2514. SCIP reaches the same place with its
document-scoped `local <id>` keyspace.

Top-level functions and class methods are NOT locals and keep their ids
byte-for-byte. That is the bound on the churn: this touches only symbols that
are unreachable from outside their own document anyway.

RESOLUTION JOINS BY POSITION, NOT BY NAME. `resolveDefGraphId` matches a def
to its node on (file, label, line, simple name). A def and its node are the
same construct, so this needs no scope chain at all — which is the point:
re-deriving the chain in the resolver would be a second implementation that
could silently disagree with the first. A genuine tie (two callables on one
line) stores an AMBIGUOUS_POSITION tombstone and falls through to the existing
name keys rather than picking by source order. Without this the node ids were
already correct and calls STILL resolved to the file-level symbol — the fix is
only half a fix without it.

JS/TS GAIN BLOCK SCOPES. They emitted no `@scope.block` at all, so the
resolver could not tell two `const pick` in sibling branches apart. Giving
them distinct ids made that visible as DUPLICATE edges — each call resolving
to BOTH — which is worse than the collapse it replaced. `(statement_block)
@scope.block` supplies the missing environment record. The other half of the
ECMAScript rule was already implemented and waiting: `tsBindingScopeFor`
hoists `var` past blocks to the enclosing Function/Module while `let`/`const`
bind innermost, and its docblock already claimed "the innermost default covers
these" for block scopes that did not exist. All 82 scope-resolution test files
pass with blocks on.

Verified by probe, per case: two locals in different functions, a local inside
an ANONYMOUS function (`outer.fn@1:9.save@2:4`), sibling blocks resolving to
their own binding, `var` still hoisting out of its block, a nested named
`function` vs a file-level one, PHP composing with the `$` sigil from #2693,
and Python. Top-level/method ids unchanged, asserted directly.

Every assertion is on the EDGE, not on node existence. Ids are built twice and
independently — definition phase and caller attribution — and a one-character
disagreement makes the caller attach to a node that does not exist and the
edge vanish, with nothing thrown and no test failing. An edge assertion can
only pass if both phases agree.

INVALIDATION. INCREMENTAL_SCHEMA_VERSION 17 -> 18 and SCHEMA_BUMP 24 -> 25:
persisted node ids change for every function-local callable, and the cached
scope tree lacks block scopes. A top-up would leave unchanged files on the old
ids while changed files emit the new ones, splitting each symbol in two.

Bench fingerprint unchanged and both timing budgets pass. The one full-suite
failure (incremental-orchestration) passes in isolation — its log shows stale
init locks and WAL reclaim, i.e. LadybugDB contention under the parallel run.

Refs #2699

* perf(ingestion): emit block scopes only where they bind something (#2699)

Block scopes make `let`/`const` in sibling blocks distinct bindings, which is
what stopped a call in one branch resolving to both. Emitted naively — one
scope per `statement_block` — they also 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.
     Nothing can be declared between a function and its own body, so a binding
     in either resolves identically — the inner scope is pure depth.
  2. A block that declares no `let`/`const`/`class`/`function` binds nothing,
     so it is transparent: a lookup finds nothing in it and walks to the
     parent. `var` is deliberately excluded from that list — it hoists past the
     block to the function, so a block containing only `var` still binds
     nothing.

MEASURED, on a 762-file / 228k-line TypeScript corpus (gitnexus/src), min of 6
warmed reps with the cold first rep discarded:

    block scopes emitted   19,389  ->  5,331     (-72%)
    total scopes           35,942  ->  21,884    (-39%)
    analyze wall time      +9.8%   ->  +1.6-2.5% vs pre-#2699
    peak RSS (whole tree)  2398MB  ->  2434MB    (+1.5%, inside run-to-run noise)

The filters themselves are free: scope emission over the same corpus measured
12.6s naive vs 12.5s filtered.

Wall-clock on a shared runner has a ±10% spread run to run, which is wider than
the effect being optimised, so the durable gate added here counts scopes
instead. `bench/scope-emission/measure.mjs --check` asserts an EXACT scope set
over a synthetic corpus that mixes the shapes the filters discriminate between
— function/method/arrow bodies, non-declaring if/else/for/while/try, blocks
that declare `const`, and a `var`-only block. Baseline is 2 block scopes per
module: only the two `if`/`else` branches that declare `const chosen`. If the
filters regress that number jumps immediately, in a way wall-clock CI could
never resolve from noise. Wired into the existing benchmarks job.

Behaviour is unchanged: 86 scope-resolution and identity test files, 1371
tests, all green — including the sibling-block case this could plausibly have
broken — and the callable-value-flow fingerprint is untouched.

Refs #2699

* test(bench): re-baseline the TS/JS scope-capture fingerprints for #2701

`bench/scope-capture` fingerprints the full capture set per language, and
#2701 added a `@receiver-owner.this` marker to every non-arrow function form
so a scope that BINDS its own `this` can terminate the receiver walk. That is
a capture-set change, so the TypeScript and JavaScript fingerprints moved and
the benchmarks job has been failing since that commit — I pushed it without
checking CI.

A fingerprint is a correctness gate, so this does not simply adopt the new
value. Verified first by diffing the capture-name HISTOGRAM over the same
fixture corpus against 1d308817 (the commit before #2701), which says what a
fingerprint cannot: WHICH names moved.

    typescript   @receiver-owner.this   0 -> 143
    javascript   @receiver-owner.this   0 -> 32

Nothing else. Every other capture count is byte-identical, so no existing
capture shifted and the drift is entirely the intended marker. Both languages'
scaling ratios stay well inside their 1.5 budgets (0.976 / 1.025).

Note `@scope.block` does not appear in the delta: the #2699 filters suppress a
block that is a function body or that declares no binding, and no fixture in
this corpus has a block that binds. Block-scope emission is guarded separately
by `bench/scope-emission`, whose synthetic corpus exercises exactly those
shapes.

Refs #2701

* fix(ingestion): stop the callable-prefix walk at class bodies, not only declarations (#2699)

An anonymous class owns its members, but `CLASS_CONTAINER_TYPES` lists only class
DECLARATION nodes — and a Java anonymous class has none. It is

    object_creation_expression > class_body > method_declaration

so `enclosingCallablePrefix` sailed straight through the anonymous body, reached the
enclosing method, and re-keyed the member as a function-local of that method:

    Method:src/Worker.java:Worker$1.run#0
    -> Method:src/Worker.java:Worker.makeHandler.run@7:12#0

That destroys the javac-compatible JLS identity #2550/#2555/#2562 exist to provide, and
broke four existing Java tests that this PR never touched — anonymous-class instance
identity, local-type identity, and enum-constant-body chaining.

The design was right; the boundary was blind. `CALLABLE_PREFIX_BOUNDARY_TYPES` adds the
body and anonymous-construction forms (`class_body`, `interface_body`,
`annotation_type_body`, `enum_body`, `enum_body_declarations`, `enum_constant`,
`object_creation_expression`, `object_literal`,
`anonymous_object_creation_expression`). Over-inclusion is the SAFE direction here: an
extra boundary only suppresses the nesting prefix, falling back to the pre-#2699 class
qualification.

This also falsifies the claim in the #2699 commit that "top-level functions and class
methods keep their ids byte-for-byte" — an anonymous-class method IS a class method, and
its id did change. The claim was true only for the shapes that were tested.

Also removes the dead `NO_QUALIFIED_NAME` constant, which contained a literal NUL byte.
That byte made `file(1)` report the source as `data` and made plain `grep` return zero
matches for ANY pattern in the whole 2,928-line file — which is why several greps during
development came back mysteriously empty. Two other files carry NULs; they are
pre-existing and out of scope here.

INVALIDATION. INCREMENTAL_SCHEMA_VERSION 18 -> 19 and SCHEMA_BUMP 25 -> 26. This is not
defensive: an index stamped v18 holds the WRONG Java ids, and without the bump it passes
the `=== INCREMENTAL_SCHEMA_VERSION` reuse gate and keeps them on every unchanged file.

* fix(scope-resolution): fail closed when a function-local shadows a same-named callable (#2699)

The #2699 positional join failed OPEN. On a position miss `resolveDefGraphId` fell
through to the label-agnostic, first-write-wins `simpleKey(filePath, simpleName)`, which
aliases a def onto whichever same-named callable was registered first — the exact
fabricated-caller mechanism this PR's own #2693 work already shipped once as a P0.

It misses because the two id phases anchor on different nodes BY DESIGN:
`tree-sitter-queries.ts` anchors the graph node on the outer `lexical_declaration`, while
`languages/typescript/query.ts` anchors the scope def on the inner `arrow_function` so
`anchor.range` lines up with `@scope.function` for auto-hoist. Split the declaration
across lines and those land on different LINES:

    export function run()   { const pick =
        (x) => x * 2; return pick(1); }
    export function other() { const pick =
        (x) => x * 3; return pick(2); }

    before:  run   -> run.pick@1:2      correct
             other -> other.pick@6:2    correct
             other -> run.pick@1:2      FABRICATED — other() never calls run's pick

Every fixture in function-local-identity.test.ts kept the declaration and its initializer
on ONE line, where the anchors coincide. That is why the suite stayed green while the bug
shipped, and the new test deliberately splits them.

WHY NOT A BLANKET FAIL-CLOSED. A position miss is not always a collision: it also happens
where the anchors legitimately differ, e.g. a Vue SFC, whose graph nodes carry
`+ lineOffset` while scope extraction does not. Failing closed on every miss would delete
correct edges there. So the guard is keyed on evidence that the collision is REAL —
`localNameKey` records that a function-local of this simple name exists in the file
(local-identity nodes are recognisable by the `@<row>:<col>` on their last name segment).
Only then is a miss treated as ambiguity. Files with no such local keep their previous
fallback behaviour byte-for-byte.

A missing edge is the correct failure direction here: `impact` can recover from an absent
caller, but a fabricated one silently corrupts the answer.

WHY NOT UNIFY THE ANCHORS. Considered and rejected: the split is deliberate and
load-bearing for auto-hoist across every language (the `rangesEqual(anchor.range,
innermost.range)` rule), so unifying it would fight that discipline far outside this fix.

The regression test was verified to DISCRIMINATE: with the guard disabled it fails on
exactly the fabricated edge (`+ "Function:m.ts:other -> Function:m.ts:run.pick@1:2"`).

impact(resolveDefGraphId, upstream) is CRITICAL — 62 impacted, 23 direct, 6 flows — which
is precisely why the guard is gated rather than broad. detect_changes: HIGH, 8 affected

* fix(typescript): stop the enclosing-type walk at nodes that rebind `this` (#2701)

`findEnclosingType` walked `node.parent` to the top of the file with no boundary, so it
happily synthesized a `this` binding from a type that does not own the member:

    class A { outer() { const o = { inner() { return this.x; } }; return o; } }

`this` inside `o.inner` is `o`, never `A` — but the walk reached `A` and bound to it, so
every `this.…` in such a method resolved against the wrong type. Only the module-level
object literal escaped, because there was no enclosing class to reach. Applies to
JavaScript too: `languages/javascript/captures.ts` calls the same function.

Boundary set: object literals and the function forms that rebind `this` at call time.
Arrows are deliberately absent — they inherit `this` lexically, which is what makes a
class-field arrow `m = () => this.x` resolve.

WHY THE MARKER WAS NOT ALSO REMOVED FROM METHOD FORMS.

The review argued `@receiver-owner.this` over-suppresses: `synthesizeTsReceiverBinding`
returns null for static members, object-literal methods and anonymous class expressions,
so those scopes are "owned but unbound" and get suppressed, losing edges the base
resolved. Removing the marker from the method forms was tried and MEASURED, and the
result does not support shipping it:

    marker removed, probe of all five shapes:
      static -> static            RESTORED (true)
      object literal (module)     RESTORED (true)
      anonymous class expression  RESTORED (true)
      static -> INSTANCE          FALSE EDGE returned
      object literal in a class   FALSE EDGE (Nested.outer.inner -> Nested.x)

The last one is the point: this fix stops the false *synthesis*, but removing the marker
re-enables receiver-blind *name* resolution in `lookupCore`'s lexical chain, which
recreates the same wrong edge by another route. The restored edges and the false ones
come from the SAME mechanism — a name walk — so they cannot be separated by toggling the
marker. The real trade is 2 genuinely-new true edges for 2 false ones, not the 3-for-1
the plan assumed.

Corpus evidence (762 real TypeScript files, edge SETS not counts, cold cache both arms):

    baseline vs marker-removed:  net 0, REMOVED 0, ADDED 0

Neither the gains nor the losses occur in production code. Given a 1:1 true/false ratio
on synthetic shapes and zero effect on real ones, the marker stays: for a graph feeding
`impact`, a fabricated caller is worse than an absent one — the same principle applied in
the fail-closed positional join. The three shapes remain UNRESOLVED rather than wrongly
resolved; resolving them properly needs a typed binding for object literals, anonymous
classes and static contexts, which is a feature, not this fix.

Measured with an edge-SET diff harness, after both ce-doc-review passes established that
an edge COUNT cannot decide this (it conflates edges gained with edges lost, so a
near-zero net reads as "no regression"). The harness also had to wipe the index each arm
— a warm parse cache initially reported an unchanged edge set across a real behavioural
change, the same trap documented in the v24 SCHEMA_BUMP note.

detect_changes: low risk, 3 symbols, no affected processes. 85 files / 1365 tests green.

* docs(test): correct the false "three load-bearing gates" claim (#2701)

The header of `this-boundary.test.ts` asserted that all three gates were
independently load-bearing because "the false edge survived removing any one of
them alone". That was true DURING development, measured incrementally, and was
carried into the shipped comment without being re-tested against the finished
code. It is false: gate 3 (`isReceiverOwnedButUnbound` in `receiver-bound-calls`)
runs FIRST and marks the site in `handledSites`, which `emitReferencesViaLookup`
then skips — so for an explicit `this` receiver it subsumes gate 1. Removing
gate 1's `ownsReceivers` check in `gitnexus-shared/.../lookup-core.ts` leaves all
10 tests in the file passing; verified by experiment.

The gate is RETAINED, and the review's recommendation to delete it as "dead" is
rejected on evidence. `receiver-bound-calls` only suppresses EXPLICIT receivers
(`if (site.explicitReceiver === undefined) continue;`), whereas `lookup-core`'s
gate is also reached for IMPLICIT ones through `IMPLICIT_RECEIVERS` in
`resolveReceiverOwner` — a bare `m()` inside a nested `function` inside a method
goes down that path. The experiment shows the gate is UNTESTED, not unreachable;
those are different claims and only the first is supported. Deleting it on the
strength of a green test run would have removed live code, which is the same
reasoning error the corrected comment is about.

This is a documentation-only change: no behaviour, no test expectations. The
correction is recorded in place rather than silently rewritten, because the way
the claim came to be wrong — measured on an intermediate tree, then asserted
about the final one — is the reusable lesson.

Refs #2701

* test(scope-resolution): pin the block-scope ACCESSES delta as false-edge removal (#2699)

The tri-review flagged that enabling `(statement_block) @scope.block` for
JS/TS drops 114 `ACCESSES -> Const` edges corpus-wide with `added: 0`,
undocumented and untested. That was recorded as a suspected regression.

It is not one. All 274 emitting reference sites behind those 114 edges were
classified by re-reading the source at the site: 269 are member reads, the 5
others are classifier artifacts (the name recurs earlier on the line, as in
`a.b.declLine` for `b`) and are member reads too. No edge was
bare-identifier-only. Every dropped edge was a property read
(`options.baseUrl`) mis-resolving to an unrelated function-local `const` of
the same name in the same file.

The cause is not block-specific: `lookupCore` Step 1 walks the lexical chain
for every lookup, including explicit-receiver property reads. Block scopes do
not fix that, they narrow it, by moving the local off the chain of any
reference outside its block. A local declared directly in the function body
still hijacks the read; that is pre-existing and left alone here.

Two tests. The first discriminates: it fails with the block capture removed
(the false edge reappears) and passes with it. The second is a companion
invariant, identical in both arms, so that "the edge went away" cannot be
satisfied by a change that dropped Block-kind bindings outright.

Fixture notes, both of which defeated earlier attempts at this edge class:
`pruneLocalSymbols` deletes ~94% of function-local value symbols, so the
`const` under test must be kept via `keepLocalValueSymbols`; and the member
read must sit outside the block, since inside it the block is on the
reference's own chain and the false edge appears in both arms.

* docs(ingestion): correct the SCIP citation on the function-local id (#2699)

The comment justified the positional, name-bearing local id (`fn@12:9`) as
"same reasoning as SCIP's document-scoped `local <id>` keyspace". SCIP is the
wrong citation for this key shape: its `local <id>` is a per-document counter,
and the spec states that locals do not encode the name.

SCIP remains prior art for the document-scoped keyspace itself, which is the
part the argument actually leans on, so the reference is corrected rather than
dropped. clang's USR for a function-local (`name@offset`) and Kythe's C++
indexer are the accurate citations for a positional, name-bearing key.

Comment only, no behavior change.

* fix(typescript,javascript): sync the function node-type lists, and test it (#2701)

Four hand-maintained lists answer "which node types are function-like":

  1. `query.ts` — the `@scope.function` / `@receiver-owner.this` patterns
  2. `captures.ts` — `FUNCTION_NODE_TYPES` (callable-flow synthesis + the
     body-block filter)
  3. `receiver-binding.ts` — `THIS_REBINDING_BOUNDARY_TYPES`
  4. `type-extractors/typescript.ts` — `THIS_BOUNDARY_NODE_TYPES`, whose
     docstring already claimed it was "kept in sync with `@receiver-owner.this`"
     with nothing enforcing it

`generator_function` (the EXPRESSION form, `const g = function* () {}`) was
added to both queries for #2701 and is present in lists 3 and 4, but was
missing from both `FUNCTION_NODE_TYPES`. Added.

That gap changes no graph output today, and the commit does not claim
otherwise. Measured on `const g = function* (x) { yield x; }; g(1)`: node and
edge sets are byte-identical with and without the entry. The `this` boundary
was already correct via the query marker — `this-boundary.test.ts` has a
passing generator case. A generator-expression binding still emits a `Const`
node rather than a `Function` one, so its call resolves to nothing either way;
that label comes from the definition rules, and closing it is a separate change
NOT made here.

So the entry is list consistency and the test is the real deliverable. It
asserts lists 1 and 2 EQUAL, and lists 3 and 4 as subsets of the query markers
with an explicit allowlist — the method forms bind their own `this` but the
class is their `this`-owner, so neither walk may stop there. Verified
discriminating: removing the `generator_function` entry fails both equality
assertions.

The lists are exported for the test; no other production surface changes.

* test(bench): gate scope emission per language, not TypeScript-only (#2699)

The scope-emission gate ran the TypeScript emitter only, so a JavaScript-only
regression shipped green. The two filters it guards 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 `BLOCK_BINDING_CHILD_TYPES` — so covering one said
nothing about the other.

Adds a structurally parallel JavaScript corpus (the same shapes with the
TS-only syntax removed) and splits `baselines.json` per language. `--check`
now also fails when a baselined language is not measured, which is how a gate
goes quietly green.

Verified the new arm bites: disabling the JS body-block filter alone takes
JavaScript from 400 to 600 block scopes and fails `--check`, while TypeScript
stays green — the exact regression the old gate would have passed.

The two languages happen to agree exactly on this corpus (2 blocks per module,
2200 scopes). That is recorded as a measured result, not an invariant: each
language is still gated against its own baseline. TypeScript's numbers are
unchanged.

* docs(plans): add provider-hook value-refs plan (#2437)

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* docs(plans): deepen #2437 plan to USES + property-dispatch design

Design revised after prior-art research (Kythe ref vs ref/call, Joern
METHOD_REF, Feldthaus field-based call graphs, CodeQL impliedReceiverStep):
registration sites emit reference-class USES, invocation is recovered by a
field-based property-dispatch pass synthesizing CALLS at member-call sites.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(scope-resolution): model provider-hook value references (#2437)

Functions referenced as object-literal property values (provider hooks like
emitScopeCaptures: emitCppScopeCaptures) previously produced no edge at all,
so impact/context reported a false-safe 0 upstream dependents.

Two coordinated halves, per prior art (Kythe ref vs ref/call, Joern
METHOD_REF, Feldthaus ICSE'13 field-based call graphs, CodeQL
impliedReceiverStep):

- Registration -> USES: new ReferenceKind 'value-ref'; TS/JS queries capture
  pair values and shorthand properties (with @reference.property-key);
  emitted as a reference-class USES edge, reason 'scope-resolution:
  value-ref'. Resolution is callable-gated so plain values emit nothing.
- Dispatch -> CALLS: new shared pass emitPropertyDispatchCalls synthesizes
  CALLS (reason 'property-dispatch', confidence 0.7, per-key fan-out cap 32
  calibrated on this repo's 16-provider hook tables) from member-call sites
  to every function registered under the same property key.

Deviation from plan: the pass owns value-ref resolution entirely via the
post-finalize findCallableBindingInScope walker — the shared registries only
see pre-finalize local bindings, so imported hooks (the c-cpp.ts case) were
unresolvable through lookupForSite; Reference.propertyKey passthrough
dropped as unnecessary.

SCHEMA_BUMP 13 -> 14: ParsedFile gains value-ref sites + propertyKey.

Verified end-to-end: impact(emitCppScopeCaptures, upstream) now reports 8
impacted / HIGH with extractParsedFile (true dispatch caller) at d=1 via
property-dispatch and the c-cpp.ts registration via USES.

Integration: same-file/cross-file/aliased/shorthand registrations emit USES;

* fix(storage): bump INCREMENTAL_SCHEMA_VERSION for callable-value-flow edges

Callable-value-flow CALLS/USES edges (#2437) can connect two files whose
content did not change, but the incremental write set only covers changed
files — a top-up against a pre-v7 index would silently omit the new edges
for every unchanged file pair, indefinitely. Force the one-time full
re-analyze (review finding 1, #2522).

* fix(storage): sanitize callable-flow sites per-site at load, log drops

The load-time validator rejected the WHOLE ParsedFile when one site was
malformed or over-bound, with no logging — and C++ legitimately emits
empty-string parameterTypes entries ('' = unknown, the
ReferenceSite.argumentTypes convention) for cv-only/ERROR-recovered types,
so real repos fell into a permanent, silent warm-cache-miss reparse loop
through the #1983-sensitive main-thread path (review finding 7, #2522).

Now: '' entries are valid in type arrays; a malformed/over-bound site drops
only itself (counted, warned once per load); only non-array garbage —
evidence the serialization itself is untrustworthy — rejects the file.
Deviation from plan §6 wording: validator-side tolerance replaces emit-side
clamps — smaller diff, same asymmetry closed at the single chokepoint.

* fix(scope-resolution): keep declarations in the union for reassigned callable cells

The binding-lookup suppression for fact-constrained cells was wholesale:
reassigning a declared function through its own name (greet = other;
greet()) deferred the call to the solver, which then refused the lexical
lookup that resolves the declaration — an unresolvable RHS yielded zero
CALLS for a call that resolved pre-flow (review finding 8, #2522).

Suppression now applies only to cells bound by FORMAL facts — its actual
purpose (a parameter whose grammar emits no declaration binding must not
adopt a same-named outer function). Copy/alias/store/load destinations keep
their declaration as an inclusion seed (Andersen-style union).

* fix(scope-resolution): count forfeited deferred sites in the budget-bailout warning

On work-budget exhaustion the deferred invoke sites end the run with zero
CALLS — free-call fallback and reference emission already skipped them —
but the warning said 'ordinary graph emission remains untouched', which is
false for exactly those sites. The warning context now carries the
unresolved deferred-site count and the comment states the real cost
(review finding: budget-bailout honesty, #2522).

* feat(scope-resolution): surface dropped property-dispatch keys in stats and warn payload

The over-cap warning carried only a count; the dropped key NAMES were

#2522; reviewer ask on the fan-out cap). The warn payload now names up to
20 dropped keys and the stats carry propertyDispatchSkippedKeys.

* refactor(scope-resolution): drop producer-less ownerQualifiedName from formal sites

No capture emitter anywhere produces @callable-flow.owner-qualified-name —
the solver branch consuming it was unreachable in production, yet the field

finding 16, #2522; YAGNI). Re-add with a real producer if C++ qualified
member declarators ever need it.

is a different, live concept and stays.

* fix(ingestion): bind subscripted callable cells to the container, not the index

terminalIdentifier iterates children in reverse, so tbl[i] = handler seeded
the INDEX variable's cell (polluting a same-named formal) and tbl[i](7)
looked up the callee under i in a different scope — no join, no CALLS edge
for the classic function-pointer-array dispatch (review finding 12, #2522).
Subscript nodes now recurse into their container field only, in both
bindingIdentifier and terminalIdentifier, across the fielded grammars
(C/C++/JS/TS/Python/Go/Java).

* fix(ingestion): make cross-function file-scope callable bindings resolvable

Two stacked gaps killed the canonical C callback-registration pattern
(fp assigned in init(), called in run()) — the exact #2437 false-safe this
PR exists to fix (review finding H1, #2522):

1. isVisibleValueBinding only consulted assignment regions and formals, so
   a call in a function OTHER than the assigning one emitted no invoke
   fact. A declared callable-typed binding is now a value binding wherever
   its declaration is visible (visibleCallableSignature).
2. The C scope query had no @declaration.variable pattern for function-
   pointer declarators — void (*fp)(int); created no scope-tree binding,
   so the seed (init) and invoke (run) cells canonicalized to different
   keys and never joined. Both bare and initialized forms now bind.

* fix(c): detect variadic parameters via the named variadic_parameter node

tree-sitter-c materializes '...' as a named variadic_parameter node; the
anonymous-token checks never matched, so variadic function-pointer
signatures were emitted with a wrong fixed arity and no '...' sentinel
(review finding, #2522). C++ is unaffected ('...' stays an anonymous token
there); the token checks remain for such grammars.

* fix(ingestion): emit invoke facts for field-stored callable member calls

The C ops-vtable pattern (o->run = handler; o->run(1)) captured the store
but never the call — the member path in emitCallFacts bailed for languages
without protocol methods, and the value-binding index recorded the member
store under the OBJECT's name ('o'), not the member's ('run') (review
finding 11/M3, #2522). Member destinations now also record their terminal
member name, and a member call whose name-cell has a visible store emits an
indirect invoke — gated on the store so plain accessor calls (map.get)
stay inert.

* fix(cpp): disambiguate (obj->*ptr)() ERROR recovery by token order

tree-sitter-cpp groups the recovered '->*' two ways depending on
error-recovery cost (identifier lengths): [identifier, ERROR '->*m'] or
[ERROR 'obj->*', identifier]. The recovery assumed the first shape, so the
second silently swapped receiver/member and dropped the call site — the
committed test passed only by name luck (review finding H2, #2522). The
identifier's position relative to '->*' inside the ERROR now decides roles.

* fix(cpp): class members are never file-local in hasFileLocalCallableLinkage

The name-keyed file-local set is populated from every static declaration,
so an in-class 'static void make();' (external linkage — in-class static
means no-instance) and any member sharing a name with a static free
function were over-marked, refusing legitimate cross-file
declaration/definition joins (review finding 13/M2, #2522). Method and
Constructor defs now bypass the name-set, per the hook's own linkage-only
contract.

Deviation from plan step 13: the regression is a unit-level contract pin
rather than an end-to-end join test — C++ merges out-of-line member
definitions onto the member node by qualified identity, so the graph shape
cannot discriminate the join refusal for members.

* fix(cpp): classify parameter passing mode from the declarator chain only

A whole-subtree scan for reference_declarator inverted copy vs alias:
void reg(void (*cb)(int& out)) marked the by-value pointer cb as
'reference' because of the NESTED parameter's int&, making the solver
back-propagate formal targets into every caller's argument cell — alias
semantics for a copy (review finding 14/M5, #2522). The chain walk never
descends into nested parameter lists; a reference anywhere ON the chain
(int& x, void (*&cb)(int)) still aliases.

* fix(ruby): bare identifiers are calls, not callable references

Ruby parses a receiver-less zero-arg method call identically to a variable
read, so 'action = process' — which CALLS process and stores its return —
seeded action with the callable and minted a wrong CALLS edge from any
dispatch through it, confirmed end-to-end (review finding 15/HIGH, #2522).
New provider knob bareNamesAreCalls: a bare name that is not a provably
local value binding and not an explicit reference form (method(:x),
lambda/proc) emits no flow fact, on both the assignment and argument paths.

* fix(go): pair multi-value := positionally instead of cross-wiring

The shared field fallback took the FIRST LHS identifier and the LAST RHS
identifier of Go's expression_list pair, cross-wiring 'a, b := f, g' and
synthesizing a garbage comma-joined qualified name — the real relationships
were silently dropped (review finding 16, #2522). extractAssignment may now
return multiple pairs; Go pairs list entries positionally and emits nothing
for a length mismatch (multi-return call RHS).

* fix(java): drop get/test from callableProtocolMethods

'get' and 'test' collide with ubiquitous non-functional-interface APIs
(Map/List/Optional/Future.get), so every ordinary container access emitted
a spurious callable-object invoke fact — high-volume misleading graph facts
with a cross-wiring risk on receiver-name reuse (review finding 17, #2522).
Supplier.get/Predicate.test dispatch is deliberately traded away until the
check can gate on the receiver's declared type.

* fix(rust): pin the qualified-name no-degrade guard as a hard invariant

Rust's scoped_identifier callable-reference capture over-includes unit enum
variants and associated constants (Shape::Square seeds as if callable);
they stay edge-free only because resolveSeedCandidates refuses to degrade
an unresolved qualified name to a simple-name lookup (review finding 18,
#2522). Capture-side type filtering would false-negative on tuple-variant
constructors, so the guard IS the contract: documented as a hard invariant
(Go's mis-shaped multi-value forms also rely on it) and pinned end-to-end.

tree-sitter-php has no 'optional_parameter' — defaults ride on

* fix(cobol): detect procedure pointers on fixed-format sources

Two stacked defects made the feature a no-op on classic sequence-numbered
fixed format (review finding 20/H3, #2522):
1. parseDataItemClauses' USAGE alternation knew POINTER but not
   PROCEDURE-POINTER/FUNCTION-POINTER, so the dataItems filter was dead.
2. The raw-line fallback scanned UNCLEANED text, where the sequence number
   satisfied the leading digits and the LEVEL NUMBER got captured as the
   pointer name. It now scans preprocessed lines and requires a letter-
   initial name (COBOL data names must contain a letter).
161 COBOL preprocessor/copy-expander tests stay green; free-format matrix

* fix(cobol): skip comment lines in SET seed/copy scans

A commented-out SET (indicator-column '*'/'/' or free-format '*>')
produced a live seed and a false CALLS edge from dead code (review
finding 21/M1, #2522). The scan now skips indicator-column comment lines
and strips inline '*>' tails before matching.

* docs(architecture): document callable-flow-only mode and skipped-key reporting

The Callable-value flow section omitted scopeResolutionEdgeMode:
'callable-flow-only' — a real emit-pipeline branch that suppresses all
ordinary emission for standalone providers (review finding 22, #2522) —
and predated the skipped-key names/stats surfacing.

* docs(scope-resolution): correct value-ref resolution attribution and stale pdg-gating comments

The value-ref contract comment claimed MethodRegistry resolution — the
mechanism is the post-finalize findCallableBindingInScope walker owned by
emitPropertyDispatchCalls (resolveReferenceSites skips these sites). Three
'only under --pdg' calleeIdSink comments were falsified by the #2437 gating
change (callee-id-sink.ts's header was updated; these copies were missed).

* test(ingestion): direct unit coverage for synthesizeCallableFlowCaptures

The 1,100-line shared synthesizer had no test naming it — only downstream
consumers were covered (review finding 24, #2522). Pins seed/invoke/
formal/argument emission, subscript container binding, store-gated member
invokes, produced-value guards, and the bareNamesAreCalls knob over a
minimal options object so assertions target the synthesizer's own
semantics.

* test(resolvers): deepen shallow-language coverage; fix Kotlin/Swift reassignment gaps it exposed

Adds the COBOL SET x TO y copy-branch scenario and conditional-assignment
scenarios for Kotlin, C#, Swift, and Dart (10 languages previously had one
generic case each — review finding 25, #2522). The new scenarios exposed
two real capture gaps, fixed here:
- tree-sitter-kotlin's 'assignment' node is fieldless, so nested
  reassignments (chosen = ::target inside a block) produced no flow facts;
  Kotlin's extractAssignment now decomposes it positionally.
- tree-sitter-swift fields its assignment as target:/result:, neither in
  the shared fallback's field lists; both added.

* test(infra): literal-validation gate for callable-capture option Sets

The #1920 gate validates query literals and exported configs but not the
module-private *_CALLABLE_CAPTURE_OPTIONS Sets consumed by the shared
synthesizer — a typo'd node type silently captures nothing (PHP shipped a
dead 'optional_parameter'; review finding 26, #2522). Every <key>NodeTypes
Set literal is now validated against its language's grammar; name-carrying
sets (callableProtocolMethods, memberPointerOperators) are deliberately
outside the contract.

* test(storage): centralize corrupt-fixture casts into makeStoreEntry

The callable-flow store tests scattered 'as unknown as' double-casts per
fixture (review finding 27, #2522; standing no-as-any rule). One typed
helper now owns the single controlled escape hatch for building malformed
serialization-boundary payloads.

* chore(bench): refresh capture fingerprints after review fixes

python-scope: the committed baseline (8d5c3699) never matched this
branch's code — CI's benchmarks arm was red on the PR head (review
finding 2/HIGH, #2522); regenerated (a99e69ab), scaling 1.04 in budget.
scope-capture: ruby/cpp/swift/java/kotlin drifted from the review-fix
commits (bare-name suppression, passing modes + ->* recovery, assignment
fields, protocol narrowing, positional assignment); all 14 languages
re-verified PASS with ratios <= 1.18 against the 1.5 budget.

docs/ is gitignored (local working docs); the plan files were force-added

* test(golden): regenerate captures goldens after callable-flow review fixes

The per-language digest guards (csharp/go/php/python/ruby/rust/swift)
locked the pre-fix capture output; the review-fix series intentionally
changed it — store-gated member invokes, subscript container binding,
Ruby bare-name suppression, Swift assignment fields, positional pairing.
Regenerated with UPDATE_GOLDEN=1; clean verification run 59/59; all other
parity/golden guards (pipeline-graph, spring-route, python parity) pass
untouched at 33/33.

* fix(ingestion): prototypes are callees, not callable value cells

The cross-function visibility fix indexed EVERY signature-bearing
declaration as a value binding — including plain function/method
prototypes (void f(int);). Every call to a declared function then became
an indirect invoke, and with emitCanonicalInvokeReference (C/C++) minted a
free-call reference that resolved through the registry, bypassing the
precise passes' two-phase/ambiguity/subobject suppression — eight phantom
CALLS edges in the cpp resolver suite on CI.

Only declarations whose binding identifier sits under a pointer/
parenthesized declarator (callable-typed variables like void (*fp)(int);)
create value cells now. cpp resolver suite 331/331; callable-value-flow +
C/C++ suites 181/181 (the cross-function fp regression still passes); cpp
fingerprint rebaselined, both bench gates PASS.

fix: Java cast-wrapped and this.method() call edges (#2357)
* fix: resolve Java cast-wrapped and this.method() call edges

Two fixes for missing call edges in Java method resolution:

1. compound-receiver.ts — cast expression handling:
   - Strip (Type) cast wrappers from receiver text, tracking the
     outermost meaningful cast type
   - Resolve directly to the cast type class (not the field's
     declared type), since the cast narrows the receiver type
   - Add this.field chain walker for field-access receivers
   - Replace text → workingText throughout the function body

2. scope-resolver.ts:
   - Enable resolveThisViaEnclosingClass: true for Java
     (activates Case 0.5 in receiver-bound-calls.ts)

Verified on a large-scale Java codebase with no regressions.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* chore(scope-resolution): format compound-receiver.ts with prettier (#2353 review F10)

Mechanical prettier --write from repo root — 6 brace-expansion sites and one
ternary re-join, zero logic changes. Clears the quality/format CI failure
that was blocking CI Gate on PR #2353.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(scope-resolution): pin working Java cast-receiver shapes (#2353 review F3)

Fixture-backs the cast resolutions PR #2353 gets right — simple cast,
nested/CFR cast, cast over this.field, and the deliberate declared-type
fallback for a resolvable-shape cast to an unindexed type — each with a
same-named decoy method on the receiver's declared type so later refactors
cannot silently regress them. No resolver changes; tests are green as-is.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(scope-resolution): resolve nothing for unparseable cast types (#2353 review F1)

A receiver paren-group that is type-shaped but unparseable — generic
(List<String>), array (Foo[]), fully-qualified (com.example.Foo) — is a
cast whose type cannot be looked up. Stripping it and falling through
resolved the pre-cast expression's own declared type, emitting a
confident wrong CALLS edge. Classification is now three-way per peel:
simple identifier → capture (outermost wins), type-shaped-unparseable →
resolve nothing (pre-#2353 behavior; noise casts after a captured type
still win), anything else → not a cast, text left untouched. Cast
candidates require a non-empty trailing expression, so plain
parenthesized receivers never capture a cast type.

Red-first: all four shapes reproduced the wrong edge before the fix;
golden digest byte-stable after.

* refactor(scope-resolution): delete duplicate this.field walker, seed literal-this chain heads (#2353 review F4/F5/F7)

A/B against the fixture corpus confirmed the generic per-segment walker
(head resolved via the synthesized this typeBinding) already covers every
method-body this.field chain — only initializer contexts (instance
initializer block, field initializer) were walker-dependent, since no
function scope exists there to carry a this binding. Deleting the
duplicate walker removes the naive chainRest.split('.') (F5) and the
widened fieldFallback use (F7) with it; the findEnclosingClassDef head
seed is the deliberate residue covering initializer contexts —
head-resolution only, the per-segment walk stays the single shared
implementation. Post-seed edge set is byte-identical to pre-deletion.

* feat(scope-resolution): gate cast stripping behind opt-in stripReceiverCastExpressions (#2353 review F2)

Cast handling in resolveCompoundReceiverClass now runs only for
languages that opt in via the new ScopeResolver toggle (default off);
Java is the sole opt-in. The peel loop is extracted into the pure,
exported stripCastWrappers helper (placed with the file's other pure
string helpers) so it can be unit-tested directly. Non-opting languages
see receiver text untouched — pre-#2353 behavior by construction
(golden digest unchanged, TS/C++/C# suites green, 796/796). Shared-code
comments are language-neutral per AGENTS.md; the contract JSDoc carries
the classifier grammar, the second-language escalation rule, and the
Case 3b/Case 4 pass-through non-goal.

* fix(scope-resolution): cap cast-peel iterations in stripCastWrappers (#2353 review F8)

MAX_CAST_PEEL = 16 (each cast level costs at most two peels, so this
covers 8-level nesting with headroom — real cast nesting, including
decompiler output, is a handful of levels). Each peel rescans the
working text for its matching close paren, so pathological nested-paren
input was O(N²); the cap bounds it at O(N·16). Exceeding the cap bails
all-or-nothing with the original text (not-a-cast outcome). Adds the
helper's first unit tests: 14 scenarios covering capture, unparseable
shapes, redundant-paren unwrap, captured-type precedence, rawName
no-op, over/under-cap, and unbalanced-paren termination.

* fix(scope-resolution): revert Java resolveThisViaEnclosingClass, pin Case 4 bare-this dispatch (#2353 review F6/F9)

Remove resolveThisViaEnclosingClass from the Java scope resolver: the
toggle's own contract doc prescribes keeping it disabled where Case 4
(the synthesized this typeBinding) already handles this, and Case 0.5's
C++-authored semantics (hiddenByName arity-hiding, method-before-field)
provably bypass the interface-dispatch fan-out only Case 4 emits.

A/B gate (new java-this-dispatch pinning fixtures): flag-off 7/7 green;
flag-on 2/7 red (hiddenByName drops the this.greet overload site —
masked by a free-call-fallback 'local-call' edge — and the
interface-dispatch fan-out is missing). Corpus A/B over all 54 java-*
fixtures: 2 fixtures differ — java-this-dispatch (reason
'local-call'→'global' on the bare-this overload site; +2
interface-dispatch fan-out edges flag-off) and java-this-field-chain
(2 initializer-context bare-this ACCESSES reads emitted only by Case
0.5, which Case 4 cannot resolve — no synthesized this binding without
a Function scope; the corresponding CALLS edges are unaffected via the
F4 commit's literal-this head seed).

Also (F9): insert Case 0.5 into the I4 case-order listings (contract +
receiver-bound-calls header, now 8-case, marked gated) so the next flag
flip is visible at review time; the two 'sole C++ language' comments
are accurate again unedited.

* fix(scope-resolution): restrict literal-this head seed to initializer contexts (#2353 review follow-up)

Final-review finding (two independent reviewer angles): the literal-this
chain-head seed landed ungated in shared code, so any language's
this-headed chain in a scope without a synthesized this typeBinding —
including contexts where the language DELIBERATELY leaves this unbound
(object-literal methods, nested plain functions) — would seed from the
lexically enclosing class. isInitializerContext now permits the seed
only when no Function scope sits between the site and its class, which
is precisely the field-initializer / instance-initializer shape the
seed exists for. Adds a TS guard fixture pinning that an
object-literal method's this.field.method() chain emits no fabricated
edge (mechanism did not empirically reproduce even ungated — the
restriction is conservative hardening, and the pin keeps it that way).

* chore(scope-resolution): attach stripCastWrappers JSDoc, fast-path non-paren receivers (#2353 review nits)

Two final-review nits: a blank line detached the helper's 30-line
classification-contract JSDoc from the declaration (IDE hover showed
nothing at call sites); and the gate now skips the helper call plus
result allocation for the majority of receivers that cannot be casts
because they do not start with '(' — the helper's own check stays as
the safety net.

* bench(scope-capture): rebaseline Java fingerprint for new #2357 fixtures

The scope-capture correctness fingerprint hashes captures over the
java-* fixture corpus; the three fixture dirs added by this PR
(java-cast-receiver, java-this-field-chain, java-this-dispatch) extend
that corpus, so the fingerprint moves. Verified purely additive: with
the three new dirs parked, the fingerprint reproduces the prior
baseline byte-identically — no emit/capture behavior changed.
--check now passes for all 14 languages.

* fix: scope Nuxt auto-import resolution

* fix: address Nuxt auto-import review follow-ups

* fix(ingestion): capture only LHS binding names in Nitro server-util exports

The Nuxt server-util export scanner ran a declarator regex over the whole
`export const …` right-hand side, so it registered RHS tokens as auto-import
names: arrow-function parameters (`export const f = (event) => …` → `event`),
object-literal keys (`export const c = { onError } ` → `onError`), and bare
operands. It also dropped generic-typed declarators
(`export const x: Map<a, b> = …`) because the type-annotation skip broke at the
comma inside the generic. Both produced wrong/missing auto-import CALLS edges.

Capture only the leading binding name of each top-level declarator via a
depth-aware comma splitter (tracks (), [], {}, <>), skipping destructuring
patterns. Nitro auto-imports only surface top-level binding names, so the RHS
is never parsed. Adds unit coverage for the param/object-key/operand/generic
and multi-declarator forms.

* fix(ingestion): stop Nitro server callers resolving client composables

`getNuxtAutoImportEntry` fell back to the client composable map when a
`server/api|routes|middleware` caller's name had no `server/utils` entry. But
Nitro only auto-imports `server/utils/**` into the server context — app
`composables/` are Vue-app-only — so that fallback minted CALLS/IMPORTS edges
Nitro never creates (e.g. a server route "calling" a composable it cannot see
without an explicit import).

Server callers now resolve the server map only. Restructure the barrel-directory
integration test to use a client caller (which legitimately auto-imports the
composable) so `index.*` resolution stays covered, and add a negative assertion
that `server/api/route.ts` emits no edge to `composables/*` while its real
`server/utils` call still resolves. Unit test locks that a server caller does
not fall back to a client-only name.

* fix(ingestion): let unresolved explicit imports shadow Nuxt auto-imports

The explicit-import suppression index only recorded import local names whose
edge resolved to a file (`edge.targetFile !== null`). An explicit import from an
unresolved external package — `import { useAuto } from '@vueuse/core'; useAuto()`
— therefore escaped suppression, and the post-resolution hook emitted a spurious
Nuxt auto-import CALLS edge for a name the file already imports explicitly.

Record the local name regardless of whether the import resolved: an explicit
import is authoritative shadowing intent. Adds an integration fixture importing
from an external package and a (non-vacuous) assertion that it emits no nuxt
edge.

Claude-Session: https://claude.ai/code/session_01T4W25WLfYD1JNy8icxeLPU

* fix(ingestion): let type-annotated params shadow Nuxt auto-imports

hasLocalBindingInScopeChain only consulted scope.bindings, but type-annotated
function parameters live in scope.typeBindings (the TS scope query records them
as `@type-binding.parameter`, not `@declaration`). A parameter named like a
composable therefore failed to suppress the auto-import, leaking a spurious
CALLS edge.

Also check scope.typeBindings for the name (same-file scopes only). typeBindings
holds value-space binders' type facts (parameter annotations, `self`, variable
annotations) and never a pure type that belongs to callable space, so this
cannot over-suppress a real auto-import.

Documents the residual: function-typed params (`p: () => void`), untyped params,
destructured locals, and catch-clause vars are captured by neither map and still
leak — closing that needs shared scope-query changes beyond this feature, left
as a follow-up. Also adds a no-vacuous-pass guard to the shadowing/noise test.

* fix(ingestion): treat server/plugins and server/tasks as Nitro runtime

isNitroServerRuntimeFile only matched server/api, server/routes, and
server/middleware. Nitro also auto-imports server/utils into server/plugins
and (since Nitro 2.6) server/tasks, so callers there were misrouted to the
client composable map. Extend the prefix set (now a named constant) to cover
them.

perf(ingestion): Linux-kernel-scale analysis — worker-pool parse + finalize O(n²) + scope-resolution memory wall (#1983) (#2038)
* fix(ingestion): reduce parse-phase memory for huge repos (#1983)

Stop retaining full parse-cache chunks in RAM alongside the merged graph,
slim on-disk shards, defer worker ParsedFile emission for scope-resolver
languages, and add GITNEXUS_DEBUG_HEAP probes for OOM diagnosis.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(ingestion): address #2038 tri-review findings (parse-phase memory)

Resolves the confirmed review findings on PR #2038:

- P1: thread exportedTypeMap through the sequential parse path
  (processParsingSequential) so a no-worker run over a partially-warm
  cache no longer silently drops the sequential-miss files' exported
  types. Cache hits made exportedTypeMap.size > 0, suppressing the
  end-of-loop buildExportedTypeMapFromGraph rebuild, but the sequential
  path never populated the map. Regression test added (fails on the
  pre-fix tree, passes after) plus a fully-sequential differential oracle.
- P2: saveParseCache builds its on-disk index from hashes actually
  written/copied (writtenKeys), never a usedKeys hash whose shard write
  or copy was skipped — no more phantom index entries.
- P2: add a unit test asserting SCOPE_RESOLUTION_LANGUAGES stays in sync
  with SCOPE_RESOLVERS (asymmetric drift would lose a language's ParsedFile).
- Backfill cache coverage: loadParseCacheChunk missing/corrupt -> undefined,
  pruneCache onDiskKeys branch, slim preserves nodes, saveParseCache
  copy-evicted-shard round-trip.
- Cleanups: single-source heap-probe gating via isDebugHeapEnabled();
  hoist the per-chunk mkdir in persistParseCacheChunk behind a
  process-scoped Set; gate COBOL's unused worker-side ParsedFile
  extraction (graph nodes still come from cobolPhase) while keeping
  fileCount/progress unconditional.

* refactor(ingestion): remove dead worker-side ParsedFile extraction

After #2038 gated worker `ParsedFile` emission behind `!isScopeResolutionLanguage(language)`, and with all 16 SupportedLanguages registered in SCOPE_RESOLVERS, that gate was structurally always true — the worker already produced no ParsedFiles and scope-resolution re-extracts each file from source on the main thread (run.ts). Remove the now-dead machinery:

- Drop both worker `extractParsedFile` call-sites (tree-sitter processFileGroup + the standalone-provider branch) and the `result.parsedFiles.push`. The standalone branch keeps fileCount/onFileProcessed per file. `result.parsedFiles` stays declared but empty (field removal deferred).
- Remove the now-orphaned `scopeSourceKind` var + `ScopeCaptureSourceKind`/`extractParsedFile`/`isScopeResolutionLanguage` imports.
- Delete the consumerless `migrated-languages.ts` (isScopeResolutionLanguage + SCOPE_RESOLUTION_LANGUAGES) and its drift-guard test — parse-worker was their only importer. Also improves AGENTS.md "shared ingestion code must not name languages" compliance.

`extractParsedFile` and the scope-extractor-bridge stay (scope-resolution/run.ts + Vue resolver use them). Behavior-preserving: worker-sequential-parity passes before and after; tsc/eslint clean; no baseline/golden drift.

* refactor(ingestion): worker-pool-only parsing; remove sequential parser (#1983)

Completes the #1983 huge-repo parse-OOM effort by making the worker pool
GitNexus's sole parse path.

Parallel serialization (the perf core): workers serialize their ParsedFiles to
a disk store in parallel and stream them back to scope-resolution, so the main
thread no longer re-parses every file (the tree-sitter native-memory leak that
caused the OOM). Adds chunk merge-pipelining + work-proportional chunk sizing so
the pool stays saturated.

Remove the sequential parser: `--workers 0`, `GITNEXUS_WORKER_POOL_SIZE=0`, and
`skipWorkers` now hard-error (no silent degrade — #1741); the small-repo
threshold no longer selects an in-process path; pool creation stays lazy /
cache-miss-gated so warm all-hit runs never spawn workers.

Worker-path parity fixes — removing sequential surfaced two pre-existing gaps
that tiny-fixture tests had masked by running below the worker threshold, both
fixed by carrying per-file metadata as DATA across the worker boundary (never
re-parsing on the main thread, preserving the OOM fix):
  - C++: templateConstraints wired into worker node identity (SFINAE overload
    disambiguation) + ADL / inline-namespace capture side-channel serialized
    onto the ParsedFile.
  - Kotlin: companion-scope side-channel serialized the same way (companion /
    static dispatch).

Validation: tsc + build clean; full suite green (10,190 pass — the only
deterministic failures were the now-fixed C++/Kotlin worker-path gaps; the 2
remaining full-run failures are pre-existing load flakiness, green in
isolation); cpp-pipeline benchmark stays linear on a 1-worker pool.

* fix(ingestion): wire C static-linkage side-channel + ADL O(1) collect + tri-review cleanups (#1983)

Follow-up to the worker-pool-only refactor, from a tri-review of the parse path.

- C static-linkage side-channel (P1): cProvider had no collect/applyCaptureSideChannel,
  so on the now-sole worker path C `static` file-local marks were lost across the worker
  boundary -> false cross-file CALLS edges + over-broad #include wildcard visibility on
  every C analysis (the Linux kernel is C). Mirror the C++/Kotlin wiring: serialize
  `staticNames` per file onto ParsedFile.captureSideChannel and restore it on the main
  thread (no re-parse). + a worker-path regression test (the existing c-static-isolation
  fixture passed vacuously — its collision resolves via #include before the global
  free-call fallback ever consults static-linkage).

- captureSideChannel `kind` discriminant: add `kind:'cpp'`/`kind:'c'` tags + guards
  (Kotlin already had one) now that C/C++/Kotlin share the single generic field.

- Perf: collectCppAdlSideChannel scanned the whole argInfoBySite/noAdlSites maps per file
  (O(F^2) per sub-batch, ~100M parseSiteKey calls at kernel scale). Add per-filePath
  lockstep indexes -> O(1) collect; serialized snapshot byte-identical.

- Cleanups: inline the one-line processParsingWithWorkers wrapper into processParsing;
  drop the always-empty WorkerExtractedData.calls/assignments/constructorBindings fields;
  remove the voided astCache param from processParsing; refresh stale "sequential
  fallback" JSDoc.

Validation: tsc + build clean; cpp 297/297, c 8/8 (incl. the new worker-path
static-linkage guard), typescript + parsedfile-store green; cpp ADL benchmark stays linear.

* perf(scope-resolution): index C/C++ #include resolution in finalize (O(n²)→O(n))

Kernel-scale C/C++ analysis ground in finalizeScopeModel because three
per-#include operations each did a full O(F) scan with no index — the
finalize O(n²) that surfaced once the #1983 parse-phase OOM was fixed:

- expand{C,Cpp}WildcardNames: parsedFiles.find() per wildcard edge → O(R·F)
- resolveImportTarget: new Set(allFilePaths) rebuilt per #include
- resolveCImportTarget: suffix-match scanned all workspace paths

Each is replaced with a WeakMap-per-pass index keyed on the stable
parsedFiles/allFilePaths references that scope-resolution run.ts passes
once per pass:

- Map<ScopeId,ParsedFile> for wildcard expansion (c/static-linkage.ts +
  cpp/file-local-linkage.ts)
- memoized augmented header set (c/scope-resolver.ts + cpp/scope-resolver.ts)
- basename-bucketed suffix index in resolveCImportTarget (c/import-target.ts),
  shared by C and C++ since resolveCppImportTarget delegates to it

Collapses the C/C++ finalize from O(R·F) to O(R+F). Pure-perf, byte-identical
edge output: 962 targeted tests green (490 C + 472 C/C++ scope-resolution);
the basename index preserves the exact endsWith('/'+target) match and the
fewest-path-components-then-lexicographic tie-break.

The kernel's ~25-30k .h headers are classified C++, so both providers must
be fixed. Proven on the Linux kernel: the C finalize completed
(sr-post-finalize lang=c → sr-end lang=c), which the pre-fix run never
reached in 16+ min of grinding.

Build-independent follow-ups (separate from this finalize fix), documented
for later: emitFreeCallFallback same-name buckets (emit phase),
buildGraphNodeLookup + precount global setup, the ParsedFile store-load,
the dart/go/ruby expand-wildcards .find siblings, and the ~26GB
scope-resolution memory floor (full kernel completion needs >~40GB RAM).

* test(bench): regenerate C scope-capture baseline for the #1983 c-static-linkage-worker fixture

bench/scope-capture/measure.mjs fingerprints emitCScopeCaptures over the
lang-resolution/c-* fixture corpus. The #1983 PR added the
c-static-linkage-worker fixture (caller.c/lib.c/lib.h/local.c — the
worker-path static-linkage side-channel test) but did not regenerate the C
baseline, so `--check` has been red on this branch (main, lacking the
fixture, still matches 0de009b).

Pure fixture-corpus drift — no c/captures.ts or query change branch-vs-main,
existing fixtures' captures byte-identical (c-captures.test.ts 45/45),
scaling stays linear (~0.97). Regenerated: 0de009b -> 39f3a83. Bench now
PASS (14 languages). Unrelated to the finalize O(n²) fix.

* perf(scope-resolution): lower kernel-scale resident memory floor + setup cost

Reduce the scope-resolution resident-memory floor and setup throughput on
huge repos (Linux kernel), the wall that remains after #1983 (parse OOM) and
the finalize O(n^2) fix (b71c77b8). Five units; all preserve byte-identical
edge output (C fixture 177n/255e + c/cpp/cross-file/php/static-linkage suites
green, 619 tests).

U1 (src/cli/analyze.ts): RAM-aware auto heap-cap. Replace the hardcoded
16384MB cap with computeHeapCapMb = max(16384, floor(0.75*effectiveRAM)),
where effectiveRAM = min(os.totalmem(), process.constrainedMemory()) with the
unconstrained-sentinel guard. Add --max-semi-space-size=128 on the respawn.
A user-supplied NODE_OPTIONS heap still wins (no re-exec). Verified: 23973MB
on a 31964MB box, 16384 floor on small machines, cgroup-aware, sentinel safe.

U2 (src/storage/parsedfile-store.ts, .../pipeline/phase.ts): export forceGc()
and call it at the per-language eviction boundary, so a finished language's
ParsedFiles are reclaimed before the next language's store-load instead of
collected lazily under the next pass's allocation pressure (which at cap>=RAM
degrades into swap-thrash). Measured on a real drivers/net/ethernet run:
C 2113->894MB and C++ 1754->1057MB reclaimed at the boundary (no fragmentation
defeat). Answers the plan's Open Question 1.

U3 (src/storage/parsedfile-store.ts): intern def objects by nodeId in the load
reviver so a SymbolDefinition's three serialized copies (localDefs /
scope.ownedDefs / scope.bindings[].def) collapse to one shared object on load.
Per-shard def pool (a def's copies are shard-local). Measured ~42% off the
def-object retained heap (3->1; 1.8M->600k distinct objects on 600k defs).

U4 (.../passes/free-call-fallback.ts): memoize pickUniqueGlobalCallable's
post-filter candidate list per (name, callerFilePath), only when no per-caller
visibility filter applies (the list is then a pure function of name+file), so
repeated free calls of one name from a file reuse the same-name-bucket scan
instead of re-walking a potentially huge bucket per site. The cached array is
read-only-consumed by the .filter()-based arity/overload narrowers. Exported
pickUniqueGlobalCallable + buildGlobalCallableIndex and added an equivalence
test (memoized == un-memoized reference for every (name, file, arity),
including warm-cache repeats and cross-file file-local exclusion).

U5 (.../pipeline/phase.ts): replace the O(L*F) per-language precount + repeated
scannedFiles.filter() with a single O(F) partition-by-language pass; bracket
buildGraphNodeLookup with scope-setup-nodeLookup heap probes so the long setup
is no longer silent.

Plan: docs/plans/2026-06-06-001-perf-kernel-scope-resolution-memory-plan.md
(U6 out-of-core global index deferred). Note: the kernel's full C++ pass floor
(~20k headers + the 8.8GB graph) likely still exceeds 24GB by itself, which is
why U6 remains the only unit that clears the wall.

* fix(test): match OOM-guidance e2e assertions to the U1 reworded hint

The analyze-heap-oom-e2e real-child-OOM test still asserted the pre-U1
wording ('...out of memory.' + a hardcoded 24576 cap). U1 reworded the hint
to mention the auto heap-cap and use a <MB> placeholder, so the three
toContain substrings no longer matched (the assertion at line 62 failed on
all platforms). Update them to the current message. The unit twin
(analyze-heap-respawn) was already updated in 85bfc216; this integration
test was missed by the targeted local run.

* perf(lbug): U6a — deterministic id-sorted graph output behind GITNEXUS_SORT_GRAPH_OUTPUT

First increment of U6 (out-of-core scope-resolution). Adds an optional
deterministic ordering of node + relationship CSV rows by their unique graph
id, behind GITNEXUS_SORT_GRAPH_OUTPUT (default OFF = today's graph-insertion
order, byte-identical — the iterator is returned untouched). With the flag ON
the CSV becomes a pure function of the node/edge SET rather than of emit order.

This is the structural enabler for the windowed/out-of-core resolve (U6b-U6d):
csv-generator.ts:518 currently iterates graph.iterRelationships() in insertion
order with NO terminal sort, so any deviation from parsedFiles-order emit would
change bytes. With U6a on, a windowed emit need only reproduce the same edge
SET, not the global insertion order — removing the single largest byte-identical
hazard from every later windowing step.

Verified: default off keeps the existing csv-pipeline suite byte-identical; on,
node rows are id-sorted and output is independent of graph insertion order
(set-build) with the same node/edge set.

* perf(storage): U6d foundation — disk-backed scope store + lazy ScopeTree

Adds scope-index-store.ts: persistScopeShards (per-file scope shards via the
proven mapReplacer + def-interning reviver) + DiskBackedScopeTree, a lazy
ScopeTree that serves getScope from a bounded LRU of decoded shards plus a small
resident skeleton (scopeId -> {shard, childIds, parent}). Exports
makeInterningReviver from parsedfile-store for reuse.

This is the contained, highest-risk mechanism of U6d (out-of-core scope
resolution): the emit passes reach the heavy per-Scope binding payload
(~17-20GB on the kernel) ONLY through scopeTree.getScope (a point lookup) and
getChildren — they never read parsed.scopes directly — so moving that payload to
disk behind getScope is transparent. Every consumer reads a Scope BY VALUE, so a
value-faithful disk round-trip is byte-identical to resolution.

Proven in isolation: DiskBackedScopeTree is value-identical to buildScopeTree
for getScope/getChildren/getParent/getAncestors/has/size across multiple files
and after LRU eviction, and preserves the def-identity collapse (ownedDefs[i]
=== binding.def). Nothing wires it yet (the resolution-pipeline integration is
the next increment) — zero production impact; default off.

* perf(scope-resolution): U6d integration — seal scopeTree to disk before emit (GITNEXUS_DISK_SCOPE_INDEX)

Wires the U6d out-of-core scope index into the live pipeline behind
GITNEXUS_DISK_SCOPE_INDEX (default OFF = byte-identical). When on:

- finalize-orchestrator builds a TransitionalScopeTree (validated, fully
  resident) instead of buildScopeTree, so finalize/propagate/resolve are
  unchanged.
- After resolve, before emit, run.ts seals it: persists the scopes to a
  file-sharded scope-index-store, swaps the model's scopeTree to disk-backed
  serving from the inside (the frozen bundle can't be reassigned, but the
  wrapper nulls its own resident backing), and drops the heavy Scope.bindings
  payload from all THREE holders — the model's tree (seal), the caller's
  preExtractedParsedFiles, and run.ts's own parsedFiles (scope-stripped copies
  for emit). Emit reads scopes only via scopeTree.getScope (a point lookup,
  now disk-backed + LRU) — verified it never reads parsed.scopes.

Purpose: lower the per-language resident PEAK (kernel C pass ~20→~12 GB by
moving the ~8-9 GB scope payload to disk) so the analysis fits on smaller-RAM
machines. At >=24 GB the full kernel already fits with U1-U5 (U2's 8.7 GB
inter-language forceGc reclaim keeps each pass under cap) — empirically
confirmed — so this is the sub-24 GB lever, not needed at 24 GB.

Byte-identical evidence: DiskBackedScopeTree/TransitionalScopeTree return
value-identical scopes vs buildScopeTree (getScope/getChildren/getParent/
getAncestors, across files + after LRU eviction + post-seal); emit reads only
getScope + referenceSites; flag-off (394 tests) and flag-on-resident (91 tests)
resolver suites stay green; an end-to-end A/B on a 212-file C+cpp+rust subset
produced identical 17,444 nodes / 31,343 edges with the seal firing per language
(c: 410→141 MB reclaimed). Kernel-scale peak-drop measurement pending the
in-flight verdict run freeing memory.

* perf(scope-resolution): U6d — id-back workspaceIndex so the disk seal can reclaim scopes

The kernel run revealed the contained scopeTree seal didn't lower the heap:
WorkspaceResolutionIndex held Scope OBJECTS (classScopeByDefId / moduleScopeByFile),
built from every ParsedFile and live through emit, so the ~28k module + class
scopes stayed pinned past the seal (sr-seal-pre 17,583 -> sr-seal-post 17,771 MB,
no drop). It was the sole residual Scope-object holder (SemanticModel holds none).

Fix: classScopeByDefId / moduleScopeByFile become id-backed ScopeByKeyView
instances — a ReadonlyMap<K, Scope> facade over a K->ScopeId map + the scopeTree,
whose .get fetches via scopeTree.getScope(id). The index now pins only ids, so
once the tree seals to disk the scopes become collectible. Byte-identical: the
view returns the same Scope the resident tree holds (or a value-identical revived
one in disk mode), and iteration keeps the old insertion order. buildWorkspace
ResolutionIndex takes an optional scopeTree (live pipeline passes it); without it
(unit tests) the legacy direct Scope-object maps are returned unchanged.

Verified byte-identical: 733 tests across workspace-index / imported-return-types
/ c / cpp / cross-file / go / java. Kernel peak-drop re-measurement to follow.

* perf(scope-resolution): U6d — precompute exportedCallableByName (fix disk-getScope thrash)

The workspaceIndex id-backing freed the kernel scopes but exposed a throughput
collapse: findExportedDefByName's workspace fallback (walkers.ts:1019) scanned
EVERY module scope's bindings per unresolved free call, and under the U6d
disk-backed scopeTree each module-scope access faulted a shard in from disk —
lib ON went ~1min -> ~7.5min.

Fix: precompute the fallback result once into
WorkspaceResolutionIndex.exportedCallableByName (simpleName -> first module-local
callable def, first-file-wins — the exact semantics the scan returned), built
from the resident module-scope bindings at index-build time. findExportedDefByName
now does an O(1) lookup with zero disk reads.

Result: lib ON ~7.5min -> 21s (cache-warm), byte-identical 17,444/31,343; 758
tests green across workspace-index + c/cpp/cross-file/go/python.

* docs: rename cryptic U-unit codes to descriptive names in comments

The plan-unit shorthand (U3/U4/U6a/U6d/...) was meaningless in the code.
Renamed in comments + test descriptions (no behavior change, byte-identical):
  out-of-core scope index   (was U6)
  deterministic output      (was U6a)
  disk-backed scope seal    (was U6d)
  def-object interning      (was U3)
  free-call candidate cache (was U4)
Also renamed throughout the PR title/summary. Pushed commit messages keep
their original U-codes as historical record.

* fix(ingestion): durable ParsedFile shards for warm-cache coverage (#2038)

On a warm re-analyze where every chunk is a parse-cache HIT, no parse worker
runs, the run-scoped ParsedFile store is cleared at parse start, and the cached
ParseWorkerResult carries no ParsedFiles (the worker writes them to the store
and empties them from the message). Scope-resolution then found an empty store
and fell back to main-thread extractParsedFile — re-opening the #1983
tree-sitter native-leak OOM the disk store closes (abhigyanpatwari review on
parse-cache.ts).

Fix: workers ALSO write their ParsedFiles to a durable, content-addressed store
(parsedfile-cache/) keyed by chunk hash, mirroring the parse cache's lifecycle
(version-gated by PARSE_CACHE_VERSION, pruned in lockstep to the surviving
keys). On a warm hit the chunk's durable shards are byte-COPIED into the
run-scoped store (no re-parse, no re-serialize -> byte-identical), so
scope-resolution streams them exactly as on a cold run. A coherence gate
re-dispatches the worker whenever a cached chunk's durable shards are missing
(migration / pruned / version-stale) -- never the main-thread extract.

- worker-pool/parse-worker: thread chunkHash through dispatch->job->flush
  (incl. split/requeue) so the worker tags its durable shard by content
- parsedfile-store: durable persist / restore / index / prune API (sibling
  dir, never cleared per run); content-addressing makes stale reuse impossible
- parse-impl: load durable index, gate the cache hit on durable coverage,
  restore on hit, dispatch chunkHash on miss
- run-analyze: prune+save the durable store to the parse cache's surviving keys
- saveParseCache returns its written keys (the durable keepKeys)

Verified on linux/lib: warm preExtractedHits = full coverage (520/207/1, zero
main-thread re-parse), byte-identical cold==warm (17,456n/31,353e), warm 8.5x
faster. New two-run + mixed-mode + coherence-gate regression test.

* fix(ingestion): clear stale scope-index-store shards on each seal (#2038)

The disk-backed scope index writes sequential s<n>.json shards into a shared
<storagePath>/scope-index-store/ dir, with the index resetting per
persistScopeShards call. A seal that writes fewer shards than a previous one
(a later language with fewer files, or a re-run of a shrunken repo) left stale
tail shards on disk indefinitely -- never read by the disk-backed tree, but
multi-GB on kernel-scale repos.

Add clearScopeIndexStore() and clear at the start of persistScopeShards: the
previously sealed language has finished emit and been released before the next
seal runs, so its DiskBackedScopeTree never reads those shards again. Unit
tests: a stale prior-run shard is removed, a fewer-files re-seal leaves no tail
shards, and the helper is idempotent.

Addresses abhigyanpatwari review on run.ts (disk hygiene for the
GITNEXUS_DISK_SCOPE_INDEX path).

fix(csharp): qualified/alias constructor names, : base/: this initializers, generic type-arg strip (#2046)
* fix(csharp): bind qualified constructor names, capture : base/: this, fix generic strip

Mirrors the Java #1928 parsing-layer fixes for the C# scope-resolution path —
the same three defect classes exist verbatim in C#:

- Qualified / qualified-generic / alias-qualified constructor calls
  (`new Ns.Foo()`, `new A.B.Foo()`, `new Ns.Box<int>()`, `new MyAlias::Foo()`,
  `new global::Foo()`) bound only `@reference.call.constructor.qualified` with no
  `@reference.name`, so the central extractor fell back to the whole-expression
  anchor and the reference name became the raw `new Ns.Foo()` text (never
  resolved). Derive the simple-name tail via the existing `terminalTypeNameNode`
  helper (handles qualified_name, generic tail, and alias_qualified_name), and
  add a query arm for the top-level `alias_qualified_name` shape that was not
  captured at all.

- `: base(...)` / `: this(...)` explicit constructor initializers, modeled by
  tree-sitter as `constructor_initializer` and never matched by the scope query,
  dropped the chained-constructor CALLS edges. Synthesize them: `this` → enclosing
  type name; `base` → the base type's bare name (first base-list entry, which C#
  requires to be the base class). Arity attached for overload disambiguation.

- `interpretCsharpTypeBinding`'s qualifier strip used `lastIndexOf('.')` over the
  whole string, cutting inside a qualified generic type ARGUMENT
  (`Dictionary<string, Ns.User>` → `User>`). Make stripQualifier generic-aware:
  reduce only the segment before the first `<`, re-attaching the generic suffix —
  multi-arg generics stay intact so the `.Values`/`.Keys` collection-accessor
  unwrap keeps working.

Tests: capture-level unit tests for every constructor shape (incl. alias-qualified,
double-match guard) and `: base`/`: this` (incl. struct/record/mixed-base);
interpretCsharpTypeBinding unit tests (the corruption case + nullable/nested/
unknown-generic edges); end-to-end resolver tests with new fixtures. The
csharp-captures golden was regenerated — drift is purely additive (only the new
fixtures; zero existing-fixture digests changed).

* fix(csharp): enhance constructor resolution and namespace qualification

- Implemented qualified constructor name binding to resolve collisions between types in different namespaces.
- Added support for `: base(...)` and `: this(...)` constructor initializers to ensure correct edge emission in the scope resolution.
- Improved generic argument stripping to prevent incorrect parsing of qualified types.
- Introduced tests for new features, including handling of interface-only base classes and qualified constructor calls.

This update addresses issues related to constructor resolution and namespace qualification, ensuring accurate type references in C# code. Tests have been added to validate these changes.

* fix(csharp): implement namespace prefix tagging for file-level type definitions

- Updated the C# ingestion process to tag file-level type definitions with their enclosing namespace path using a new `namespacePrefix` field, without altering the `qualifiedName`.
- Enhanced the scope resolver to utilize the `namespacePrefix` for resolving same-tail collisions in constructor calls, improving accuracy in type resolution.
- Added unit tests to validate the new functionality, ensuring that namespace prefixes are correctly applied to both block-scoped and file-scoped types, while leaving namespace-free types untagged.

This change addresses issues related to namespace qualification and constructor resolution in C# code, facilitating better handling of type references.

* refactor(scope-resolution): share isOverloadableCallable via util

Extract the ctor/function/method overload predicate into
callable-labels.ts so graph-bridge registration and lookup stay aligned
without duplicated private copies in ids.ts and node-lookup.ts.

fix(java): close parsing-layer coverage gaps F35/F38/F41 (#1928) (#2045)
* fix(java): close parsing-layer coverage gaps F35/F38/F41 (#1928)

Registry-primary scope-resolution path (the live one post-#942/#943):

- F35 [HIGH]: qualified / qualified-generic constructor calls. `new pkg.Foo()`
  parses as a `scoped_type_identifier` that the query bound only as
  `@reference.call.constructor.qualified` with no `@reference.name`, so the
  scope extractor fell back to the whole-expression anchor and the reference
  name became the raw `new pkg.Foo()` text (never resolved). Bind the simple
  -name tail (end-anchored last child) and add an arm for the previously
  uncaptured `new pkg.Box<String>()` (qualified + generic) shape.

- F38 [MEDIUM]: `super(...)` / `this(...)` explicit constructor invocations,
  modeled as `explicit_constructor_invocation` and never matched by the scope
  query, dropped the chained-constructor CALLS edges. Synthesize them with the
  target resolved structurally (this -> enclosing type name; super -> superclass
  tail via the shared javaBaseLookupNameNode, skipping implicit Object) plus
  arity for overload disambiguation.

- F41 [LOW]: interpretJavaTypeBinding stripped the qualifier before generics, so
  a qualified generic type arg (`Map<String, com.example.User>`) was cut inside
  the generic into `User>`. Strip generics first, then the qualifier; make the
  erasure fallback qualifier-tolerant.

F36/F37 already landed upstream (#1940/#1956); F39/F40 are legacy-bank remnants
that are no longer consumed (legacy @import skipped in parse-worker; legacy
@call never read in parse-impl) so they are intentionally left untouched.

Tests: low-level capture unit tests (constructor shapes incl. double-match
guard; super/this/enum/implicit-Object), interpretJavaTypeBinding unit tests
(qualified generic args + the corruption case), and end-to-end resolver tests
with new fixtures asserting the CALLS edges resolve to the correct constructors.

* fix(scope-resolution): register Constructor overload keys so this()/super() chains don't self-loop (#1928 F38 review)

Review of #2045 caught two gaps; both confirmed by reproduction.

P2 — F38 this() emitted a self-loop. On the java-explicit-constructor fixture,
Child(int){ this(); } produced CALLS Child()#0 -> Child()#0 instead of
Child(int)#1 -> Child()#0. Root cause is the language-agnostic graph-bridge: the
parse phase mints distinct Constructor nodes (Child#0, Child#1) carrying
parameterTypes, but node-lookup.ts registered the parameter-types / shape
overload keys only for Function/Method, never Constructor, so both ctors
collapsed onto the first-wins qualified/simple key and the caller Child(int)
resolved to Child#0 (the this() target). Extend the overload keys to Constructor
in both node-lookup.ts (registration) and ids.ts (lookup) via a shared
isOverloadableCallable predicate. Verified the edge now connects distinct nodes
(Child#1 -> Child#0); super(1)->Base#1 still correct. No cross-language
regressions (the 9 worker-path failures reproduce identically on clean HEAD).

Also harden the integration test: it matched the this() edge on name only, which
a self-loop satisfies; now assert the endpoints are DISTINCT constructors.

refactor(ingestion): delete legacy call-resolution DAG + heritage processor (RING4-1, #942) (#2023)
* refactor(ingestion): delete legacy call-resolution DAG + heritage processor (#942)

RING4-1: all 16 production languages (incl. Vue #940) are registry-primary, so
the legacy resolution legs only ran under the now-removed CI parity gate. Calls
and inheritance now resolve exclusively through scope-resolution
(Registry.lookup, preEmitInheritanceEdges, emitHeritageEdges, buildMro →
MethodDispatchIndex).

Removed:
- Call-resolution DAG: call-processor.ts legacy body (processCalls,
  processCallsFromExtracted, resolveCallTarget + all resolver/dispatch/chain
  helpers), model/resolve.ts MRO-via-HeritageMap, model/heritage-map.ts,
  type-env DAG types; inferImplicitReceiver/selectDispatch LanguageProvider
  hooks + Ruby impls; DispatchDecision/ImplicitReceiverOverride/ReceiverEnriched.
- Legacy heritage path: heritage-processor.ts, heritage-types.ts,
  heritage-extractors/, @heritage.* tree-sitter queries, heritageExtractor/
  heritageDefaultEdge/interfaceNamePattern wiring, worker + parse-impl heritage
  passes (parse-worker/parsing-processor lockstep), cross-file-impl DAG pass.
- Scope-parity infrastructure entirely (no legacy↔registry parity left to run):
  scripts/run-parity.ts, scripts/ci-list-migrated-languages.ts,
  ci-scope-parity.yml, test:parity, and the scope-parity ci.yml gate. Resolver
  integration tests still run via the normal tests job.

Kept (shared infra, NOT call-DAG-only): type-env.ts buildTypeEnv (field
extraction / structure phase / embeddings), model/resolve.ts c3Linearize +
gatherAncestors (mro-processor mroPhase), route/fetch/exported-type-map helpers
in call-processor.ts, preEmitInheritanceEdges (legacy-edge dedup simplified).

Acceptance: grep for resolveCallTarget/inferImplicitReceiver/selectDispatch/
buildHeritageMap/HeritageMap/processHeritage/heritageExtractor/@heritage. is zero
across src + test. tsc clean (both packages); resolver integration suite green
(bit-compatible EXTENDS/IMPLEMENTS/CALLS); scope-capture fingerprints unchanged
(python re-baselined: removed redundant ignored captures). ARCHITECTURE.md
updated to scope-resolution-only.

* fix(review): apply autofix feedback (#942)

ce-code-review autofix pass on the RING4-1 deletion:
- parse-cache.ts: bump SCHEMA_BUMP 2→3 — ParseWorkerResult lost its `heritage`
  field, so stale on-disk caches must invalidate (prevents a rollback replaying
  a heritage-less cache into legacy code) [api-contract P2].
- parse-impl.ts: drop 3 now-unused type imports (ExtractedCall,
  ExtractedAssignment, FileConstructorBindings) left by the deferred-block
  removal — would fail the eslint CI gate [correctness+maintainability P1].
- AGENTS.md / CLAUDE.md / scope-resolver.ts contract doc: fix stale pointers to
  the deleted "§ Call-Resolution DAG" section + removed hooks; preserve the
  language-neutrality rule [project-standards P1].
- registry-primary-flag.ts / cross-file.ts / parse-impl.ts: refresh stale
  comments referencing deleted symbols (legacy DAG, runCrossFileBindingPropagation).

* refactor(ingestion): remove the vestigial isRegistryPrimary flag (#942)

With the legacy call-resolution DAG deleted, the per-language
`REGISTRY_PRIMARY_<LANG>` / `isRegistryPrimary` / `MIGRATED_LANGUAGES` flag had
only one meaningful state — every production language resolves via
scope-resolution — and an explicit `=0` override could only *disable*
resolution with no fallback (a footgun the review flagged). Removing it.

- Delete `registry-primary-flag.ts` and the now-dead `shadow-harness.ts`
  (legacy↔registry shadow-parity tool) + its test.
- Collapse the three flag gates to their behavior-preserving outcome
  (`SCOPE_RESOLVERS == MIGRATED_LANGUAGES`, so this is a no-op):
  - scope-resolution phase now runs for every registered `SCOPE_RESOLVERS`
    entry (was `∩ MIGRATED_LANGUAGES`).
  - import-processor `addImportGraphEdge` + parse-impl `shouldAccumulate`:
    the legacy emit/accumulate paths were already inert for migrated
    languages (scope-resolution owns IMPORTS via the imports-to-edges bridge);
    drop the flag term.
- Collapse flag-branching tests to the scope-resolution path and delete the
  csharp legacy-`=0`-leg describe blocks; remove the ruby/rust-scope env-forcing
  hooks (no-ops now).
- Refresh docs/comments (ARCHITECTURE.md "one registration", scope-resolver
  cookbook, phase deps) — adding a language is now a single `SCOPE_RESOLVERS`
  registration.

Verified: tsc clean (both packages); resolver integration tests green
(747 assertions across cobol/csharp/ruby/rust/typescript/go, IMPORTS edges
intact); grep for the flag symbols is zero across src + test.

* fix(ci): drop legacy heritage-capture tests + re-baseline scope-capture fingerprints (#942)

Two CI failures from the #942 cleanup, surfaced by the tri-review + CI:

- tree-sitter-languages.test.ts: two tests asserted `@heritage.*` captures
  (Rust trait-impl, Dart extends/implements/with) that this PR removed. The
  acceptance grep used `@heritage\.` (with `@`); these reference the runtime
  capture name `heritage.trait` (no `@`), so they slipped the earlier sweep.
  Inheritance is now covered by the resolver integration suite. (fixed macos-latest)

- Re-baselined the scope-capture bench fingerprints for csharp/rust/ruby/java/
  javascript/kotlin (baselines.json) + python (python-scope/baseline-fingerprint.txt).
  The earlier test-cleanup reworded comments inside the lang-resolution fixture
  files (Shapes.cs, child.rs, derived.rb, IA.java/Plain.java, Service.js, F.kt,
  app.py) to scrub deleted-symbol references for the acceptance grep; those are
  the bench corpus, so capture node positions shifted. Capture LOGIC is
  unchanged — verified `--check` passes for all 14 langs + python. (fixed benchmarks)

* docs/chore: scrub remaining REGISTRY_PRIMARY + deleted-symbol references (#942)

Tri-review P3 follow-ups (verified):
- TESTING.md: rewrite the "Scope-resolution parity" section — the legacy
  dual-leg (REGISTRY_PRIMARY_<LANG>=0/1) and `npm run test:parity` no longer
  exist; resolver tests run once on the sole scope-resolution path in the
  normal tests job.
- scripts/bench-scope-resolution.ts: drop the inert `REGISTRY_PRIMARY_PYTHON=1`
  env set + usage hint (the flag is gone).
- ruby/scope-resolver.ts, php/captures.ts: re-point doc-comments off the
  deleted heritage-map.ts / heritage-processor.ts to the current behavior.

* fix(ci): prettier format + regenerate scope-capture goldens (#942)

Two more CI failures, same root cause as the bench re-baseline (the
test-cleanup reworded comments in lang-resolution bench/golden-corpus fixtures):

- quality/format: prettier on tree-sitter-languages.test.ts (blank line left by
  the deleted heritage-capture tests) + TESTING.md (the rewritten section).
- tests/ubuntu/coverage: `csharp-captures-golden` (and python/ruby/rust) drifted
  because the edited fixtures feed the per-language capture-golden snapshots too
  (not just the bench). Regenerated via UPDATE_GOLDEN=1. Verified safe: only the
  edited-fixture entries changed; csharp `captureGroups` unchanged (38) — digest
  shifted from comment-position only; capture LOGIC untouched. 1168 scope-
  resolution tests pass.

* test(resolvers): drop createResolverParityIt wrapper, use vitest it directly

The parity-aware `it` wrapper became a no-op when #942 removed the legacy
call-resolution DAG (it just returned vitest's `it`). Remove it entirely so
the resolver tests call vitest's `it` directly instead of shadowing it with a
local `const it` (or `pit`/`rustParityIt`):

- helpers.ts: delete createResolverParityIt + its now-unused vitestIt import
  and VitestIt type.
- 16 files: drop `const it = createResolverParityIt('x')` and import `it`
  from vitest instead.
- ruby.test.ts (pit) + rust.test.ts (rustParityIt): rename calls to `it`.
- Scrub every comment that described the removed wrapper / dual-mode parity
  skip / legacy_skip gate (vue-scope, js/ts/dart/php/python headers, rust x2,
  cpp, swift x4, rust-coverage). Genuine test rationale is kept; only the
  vestigial two-leg framing is dropped. Accurate "legacy DAG (removed in
  #942)" historical notes are retained.

No fixtures touched (no bench/golden re-baseline). tsc clean; rust+ruby
resolver suites green (323 tests, incl. #1992 worker-path parity after a
local dist build).

perf(cpp): index ADL candidates once instead of per-site rescans (#1990)
* perf(cpp): index ADL candidates once instead of per-site rescans

C++ scope-resolution `emit` dominated large-repo analysis (~6.76h on a
5,969-file repo — ~70% of the total run). `pickCppAdlCandidates` ran once
per unresolved ADL-eligible call site and each time:

- rescanned every parsed file (rebuilding a per-file scope map per call),
- scanned every workspace def (`findCppClassDefBySimpleName`), and
- used an O(scopes²) child-scope walk for hidden friends.

That is O(unresolved sites × files); with hundreds of thousands of
unresolved C++ sites the emit phase went super-linear. `resolve` (registry
lookup) was only 3.5s — the cost was entirely in fallback edge emission.

Build an `AdlCandidateIndex` once per run (lazy, guarded by `parsedFiles`
identity, reset in `clearCppAdlState`) and query it per site:

- `classDefsBySimple` — preserves `defs.byId` order so first-match /
  ambiguous semantics are identical to the legacy linear scan.
- `nsCandidates` — namespace-owned callables, with inline-namespace
  transparency.
- `friendCandidates` — hidden-friend + class-member callables; a
  parent→children scope index replaces the O(scopes²) walk.
- `nsFunctionsByQName` / `nsFunctionsBySimple` — function-reference ADL path.

A monotonic `seqByNodeId` (file-major; namespace defs before friend/member
defs within a file) lets the per-site query merge candidates across
associated namespaces, dedup by nodeId, and sort — reproducing the exact
legacy candidate set and order.

Per-site cost drops from O(sites × files) to O(associated namespaces); the
emit phase goes from linear-in-sites to flat. Benchmark (files=80): emit at
1000 sites 232ms → 9ms, 2000 sites flat at 17ms; the eliminated term scales
with file count, so the speedup is ~1000×+ on the real 5,969-file repo.

Behavior is unchanged: synthetic candidate output is byte-identical
before/after, all 270 C++ integration resolver tests and 4/4
resolver-parity-expected-failures pass, and tsc + eslint are clean.

* docs(cpp): correct ADL state-lifecycle and cache-guard comments

The header lifecycle block listed three module-level maps and named
clearFileLocalNames as the reset caller; both became inaccurate when the
candidate index was added. Enumerate all five state pieces, name the real
caller (loadResolutionConfig), and document that ensureAdlIndex's staleness
guard keys on parsedFiles identity while the index also depends on scopes
and classToNamespaceQualifiedName.

Addresses PR #1990 tri-review (U1, U3). Doc-only; no behavior change.

* test(cpp): guard the ADL seq-coverage invariant in dev/test

pickCppAdlCandidates sorts merged candidates by seqByNodeId with a `?? 0`
fallback. That fallback is unreachable today (every bucketed def is
seq-assigned in the same build block), but a future regression could break
it and silently collapse two seq-0 candidates, dropping a CALLS edge with no
error. Add validateAdlSeqCoverage and run it from buildAdlIndex under the
resolver's opt-in validation gate (NODE_ENV!=production && VALIDATE_SEMANTIC_MODEL!=0),
so a broken invariant throws loudly in dev/CI instead. Production behavior
and the hot path are unchanged. Unit-tested; 270/270 cpp integration tests
pass with the guard active.

Addresses PR #1990 tri-review (U2).

* test(cpp): parity fixture for ADL hidden-friend + namespace-callable merge

pickCppAdlCandidates merges friendCandidates (hidden friends of associated
classes) and nsCandidates (namespace-owned callables) for a single associated
namespace. The byte-identical-parity claim rested only on an uncommitted
harness. Add a fixture that reaches one callable through each bucket — combine
only via a hidden friend, process only via a namespace member — so dropping
either bucket from the merge fails the suite. Candidate order is not observable
(narrowing resolves a unique survivor or suppresses), so the guard is on the set.

Addresses PR #1990 tri-review (U4).

* test(cpp): add ADL emit-scaling benchmark

Guards the PR #1990 optimization against reintroducing the O(sites x files)
ADL candidate scan. Generates many UNRESOLVED ADL sites (class-typed arg +
a callee declared nowhere) and co-scales files and sites with N, so the old
cost is O(N^2) and the new cost O(N). Isolates the scope-resolution emit ms
from parse-dominated wall time via the logger test destination (capture
verified) and asserts the end-to-end emit ratio stays under fileRatio^1.5.
Gated by GITNEXUS_BENCH=1; runs build-free (workerPoolSize: 0).

Addresses the benchmark request alongside PR #1990 (U5).

* test(cpp): add cpp pipeline file-count benchmark

Fills the one missing per-language pipeline benchmark (cobol/csharp/go/php/
ruby/rust already have one); modeled on cobol-pipeline-benchmark.test.ts.
Generates synthetic C++ with constant per-file work and constant header
fan-out, sweeps file count through the full pipeline, and guards linearity
with a coarse time-ratio bound plus a deterministic node-ratio bound (the
non-flaky guard against reintroducing O(fileCount^2) work). Gated by
GITNEXUS_BENCH=1; runs build-free (workerPoolSize: 0).

Addresses the benchmark request alongside PR #1990 (U6).

* style(cpp): prettier-format adl benchmark

* test(cpp): rebaseline scope-capture fingerprint for new ADL fixture

The U4 parity fixture (cpp-adl-ns-plus-hidden-friend-same-name) lives under
test/fixtures/lang-resolution/cpp-*, so its lib.h + app.cpp join the cpp
scope-capture bench corpus (bench/scope-capture/measure.mjs). That is pure
fixture-corpus growth — no scope-extractor change, existing fixtures' captures
byte-identical — so the cpp fingerprint legitimately drifts (fixture_count
265->267). Rebaseline cpp to match, as #1965/#1975 did for earlier fixture
additions. Verified: --check PASS for all 14 languages.

Addresses PR #1990 tri-review (U4 follow-on).

fix(csharp): eliminate global-namespace typeBindings O(files²) OOM (#1871) (#1954)
* fix(csharp): eliminate global-namespace typeBindings O(files²) OOM (#1871)

Large C# solutions with tens of thousands of files in the global
(unnamed) namespace OOM'd / hung for hours at "Resolving types
(Csharp 2/3)". PR #1905 fixed the BindingRef twin of this via the
`workspaceFqnBindings` fast-path, but left the typeBindings
propagation loop in `populateCsharpNamespaceSiblings` untouched: it
copies every global file's module-scope return-type bindings into
every OTHER global file's `Scope.typeBindings`. With S files in the
`''` bucket and K distinct method names, that is O(S²) time and
O(S·K) memory — ~1.3B Map entries (~65-130 GB) at 36k files.

Measured on a concentrated global-namespace fixture: the per-file
copy went quadratic (1000→2000 files = 3.06× for 2× the files,
65s at 2000). Route global-namespace module typeBindings through a
new scope-independent `workspaceTypeBindings` channel populated ONCE
(O(K)) and consulted as a fallback by the typeBindings chain-walkers
(`findReceiverTypeBinding`, `followChainPostFinalize`), instead of the
per-file copy. After: 2000 files 6.3s, 4000 files 6.8s, heap linear.

This also makes resolution MORE correct, not just faster. The C#
spec makes the unnamed namespace a single declaration space whose
members are "available for use in a named namespace", so global types
are visible from every file. The old per-file copy only exposed them
to OTHER no-namespace files; named-namespace files never saw them.
Consulting the shared channel from every scope chain mirrors how
Roslyn resolves against a single `Compilation.GlobalNamespace` symbol
rather than copying symbols per file.

Strengthen csharp-pipeline-benchmark.test.ts so it would catch this:
give each file a unique method name (a shared name collapses the
module-typeBinding key and skips all copies, hiding the blow-up) and
raise the concentrated scales to 2000 so the sub-quadratic assertion
trips on the regression.

* fix(csharp): generalize shared-channel resolution to concentrated named namespaces (#1871)

#1954 eliminated the namespace-siblings O(files²) OOM only for the global
('' / no-declared-namespace) bucket. A solution with all files under one
named namespace (e.g. file-scoped `namespace Company.Product;`, common in
modern .NET) still reproduced the #1871 blow-up — and in BOTH loops: the
BindingRef per-scope augmentation (#1905's twin) AND the typeBindings
per-file copy (#1954's twin) were each still O(N²) for a named bucket.

Generalize the shared-channel approach to named namespaces:
- Add namespace-keyed channels `namespaceFqnBindings` / `namespaceTypeBindings`
  (the per-namespace analogues of `workspaceFqnBindings` / `workspaceTypeBindings`)
  plus `accessibleNamespacesByScope`, populated ONCE per named bucket from the
  existing `expandedNamespaces` derivation — O(defs), not O(files × defs).
- Make the shared walkers (`findReceiverTypeBinding`, `lookupBindingsAt`,
  `followChainPostFinalize`) namespace-aware: after the per-scope chain and the
  flat global channel miss, consult the per-namespace channels gated by the
  caller module's accessible namespaces. Language-neutral — only the C# hook
  populates the channels; the machinery names no language (AGENTS rule).
- Precedence preserved: local chain → named namespace → global. Named is
  consulted before the flat global channel because pre-#1871 named siblings
  lived in the chain / bindingAugmentations (above the workspace channel), so a
  name in both a named and the global namespace must still resolve named-first.
- `using static` member exposure and the global '' fast-paths are unchanged.

Parity-neutral: `run-parity.ts --language csharp` passes (legacy DAG ==
registry-primary, 218 tests each); the C# resolver suite (386 tests) is green.
Measured: a concentrated named namespace at 500/1000/2000 files now scales
linearly (~0.57×) and ~5.6s at 2000 files, vs the quadratic blow-up before.

Tests:
- New always-run unit coverage for the walker fallbacks
  (namespace-channel-lookup.test.ts): global `workspaceTypeBindings` (the #1954
  channel previously covered only by a gated benchmark), namespace gating /
  no-leak, named-before-global precedence, local shadowing, loop termination.
- Extend the immutability validator + invariant I8 to the new channels and
  `workspaceTypeBindings`; update the `mkIndexes` factory.
- Add a concentrated-NAMED-namespace shape to the C# pipeline benchmark with
  the sub-quadratic scaling assertion and an edge-count sanity check.
