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(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(embeddings): retry unparseable 200 responses and survive partial embedding failures (#2790)

A long-running embedding job against an OpenAI-compatible endpoint could lose
hours of work to a single transient glitch, then refuse to recover on the next
run. Four defects compounded:

1. An HTTP 200 carrying a truncated or non-JSON body was never retried.
   `classifyOutcome` treats any 2xx as success, and the `resp.json()` parse ran
   after `resilientFetch` had already returned, so the parse failure surfaced as
   a terminal error. Measured: a 503 got 3 attempts, a garbage 200 got 1.

   The parse and the response-shape check now run inside the `fetchImpl`
   callback, so a bad body is classified as a retryable failure and gets the
   same backoff as a 5xx. This also stops a garbage 200 from calling the circuit
   breaker's `recordSuccess()`, which previously erased accumulated failures and
   meant an endpoint alternating 5xx and garbage-200 could never trip it.

2. One failed `embedBatch` sub-batch aborted the entire pipeline. Failures are
   now tolerated: the sub-batch's node ids are collected and all of their
   embedding rows are deleted, so those nodes hold zero rows and are re-embedded
   later. Deleting rather than keeping partial rows is deliberate — chunk arrays
   are flat over a 16-node batch and sliced by 8, so a node's chunks can straddle
   a sub-batch boundary, and surviving rows carry the current content hash. The
   hash maps collapse per-chunk rows last-row-wins, so a partially embedded node
   would read as fresh forever and never regenerate its missing chunks.

   A run that fails 5 sub-batches in a row still aborts, and rethrows the first
   error of the streak rather than the last: after 3 failures the circuit breaker
   opens, so later errors degrade into "circuit open, retry in 30s" while the
   first still names the real defect.

3. The Phase 5 `embeddingCount === 0` fail-fast could not tell "wrote nothing"
   from "could not ask" — the count query's catch was silent. The count is now
   tri-state and only a known zero after real work is fatal. A non-numeric count
   previously bypassed the gate entirely, because `Number()` returns NaN and
   `NaN === 0` is false, and then serialized as `embeddings: null`. An unverified
   count no longer certifies `capabilities.vectorSearch.status`.

4. `saveEmbeddingCheckpoint` wrote a completion-shaped meta: it advanced
   `lastCommit`, wrote the new `fileHashes` and cleared `incrementalInProgress`.
   The first checkpoint window fires before a single embedding exists, and on a
   full rebuild the graph is still in a staging database that a crash discards.
   The next run then diffed against the advanced hashes, saw no changes and
   preserved the old graph — the "skipping wipe" symptom in the report. It now
   re-reads meta and replaces only the checkpoint, matching what the server
   endpoint already did.

A partially failed run keeps its checkpoint with the failed ids in
`pendingNodeIds`, so the next plain `analyze` regenerates them through the
existing resume path. Clearing it would have been silent data loss: a plain run
derives `shouldGenerateEmbeddings: false` once embeddings exist, so the pipeline
would never have run again. The old crash-and-abort self-healed only by accident,
via the checkpoint its crash left behind. `gitnexus status` reports the index
incomplete until the nodes recover, and `--drop-embeddings` still abandons them.

`POST /api/embed` is the pipeline's other caller and was discarding the result,
reporting "Embeddings complete" for a partial run. It now persists the pending
ids and reports the run as failed with the underlying endpoint error.

* fix(embeddings): abort a run whose sub-batch failure ratio is too high (#2790)

The consecutive-failure ceiling only catches a total outage, because any
successful sub-batch resets it. An endpoint under load shedding that alternates
success and failure never trips it, so the run walks the whole corpus, deletes
every failed node's rows and exits 0 having dropped a large fraction of the
index. The retained checkpoint made that visible in `gitnexus status`, but a run
that drops a quarter of the corpus should tell the operator to fix their
endpoint, not leave them to notice a status flag.

Adds a cumulative guard: abort once more than 25% of attempted sub-batches have
failed, evaluated as the run progresses and gated behind a floor of 20 attempted
sub-batches. The shape follows Resilience4j's circuit breaker (failure rate plus
a minimum-sample floor) because it is the only one of the surveyed designs that
answers the small-repo case — a three node repo can fail one sub-batch and never
accumulate enough sample for a ratio to mean anything. The rate sits below a live
traffic breaker's 50% because a batch indexer's job is to index the whole corpus
rather than serve degraded traffic, and above Hadoop's single-digit
`failures.maxpercent` because tolerating transient hiccups is the point of the
change this follows.

The guard reuses the existing break-then-cleanup path, so the failed batch's
DELETE still runs before the rethrow, and it wraps the retained first-error-of-
streak rather than inventing a new one, so the message names both the ratio and
the underlying endpoint failure.

* fix(server): record the embedding count after /api/embed so the next analyze cannot wipe it

`POST /api/embed` generated embeddings and wrote them to the database but never
wrote `stats.embeddings` into meta.json. Its checkpoint writer replaced only
`embeddingCheckpoint`, and the finalize write folded in nothing else.

So a repo embedded purely through the server kept whatever count the last CLI
`analyze` stamped, which is 0 for a repo analyzed without embeddings. The next
CLI run read `existingEmbeddingCount = 0`, `deriveEmbeddingMode` returned
`shouldLoadCache: false`, and `gitnexus analyze --force` wiped the database with
no cache load. Every server generated embedding was silently destroyed, with no
warning — the user just lost semantic search.

The route now measures the live count with the same query the CLI uses and folds
it into both meta writes. The measurement is tri-state and deliberately never
falls back to 0: an unverified count is written as absent rather than as zero,
because a wrong-low value is exactly what arms the wipe. It is taken after
`flushWAL()` and inside `withLbugDb`, so it describes durable rows and the
connection is still open. A partial run records its honest count too, alongside
the retained checkpoint, so the next CLI run preserves the partial index instead
of discarding it.

Found while working #2790; not part of that issue.

* fix(embeddings): retry short 200 bodies and stop laundering body-phase timeouts

Two gaps in the #2790 retry fix, both found by review.

A 200 carrying `{"data": []}` or fewer vectors than inputs passed the
in-`fetchImpl` shape check, because `every(isEmbeddingItem)` is vacuously true
for an empty array. `resilientFetch` then classified it `success` and called
`recordSuccess()`, erasing the outage signal, and the cardinality check in
`httpEmbed` threw terminally one attempt later. That is exactly the pair of
properties #2790 was filed about, still broken for this body shape — and worse
than before the fix, since the pipeline now tolerates the error by deleting
those nodes' rows instead of aborting loudly. The count check moves inside the
retried callback; the outer one stays as a backstop.

The `.json()` catch also swallowed every rejection, not just parse errors.
`AbortSignal.any([caller, timeout])` is wired to the body stream, so a stalled
body rejects with a DOMException — which, wrapped in a plain Error, defeated
`classifyOutcome`'s terminal-network test. Measured: the same TimeoutError got
3 attempts and "unparseable response" when raised during the body read, but 1
attempt and "timed out after 180000ms" when raised by fetch itself, and three
such sub-batches opened the process-global breaker that `recordNeutral()`
exists to protect. Abort-like DOMExceptions are now re-raised unchanged.

The dimension check stays outside the loop deliberately: it validates against
`config.dimensions ?? DEFAULT_DIMS`, not the request-dimensions argument, and a
width mismatch is a configuration error where retrying only triples latency and
books failures against a healthy endpoint.

Adds the negative assertion the review found missing: response body text must
never reach the user-facing error string.

* fix(embeddings): scale the sub-batch failure-ratio floor to the run

The cumulative guard needed 20 attempted sub-batches before a failure rate could
abort anything — roughly 160 chunks, or ~80 embeddable nodes at the default
subBatchSize of 8. A 50-node repo whose endpoint sheds every other sub-batch
fails half of them and still exits 0: the ratio guard is below its floor, and
every intervening success resets the consecutive ceiling.

The floor was a good choice for a first run over a small repo, where one failure
out of one sub-batch is 100% and means nothing. The defect is that every resume
run has that shape by construction — its node set is only the pending ids — so
the guard was structurally off in the one run whose entire purpose is retrying
against the endpoint that already failed.

The floor is now sized to the run: clamp(ceil(totalNodes / 16), 5, 20). The
lower bound keeps the case the flat floor protected; the upper bound preserves
today's behavior above 320 nodes and avoids a proportional-only floor perversely
weakening the guard at scale, where a sixteenth of a 20k-node repo would be 1250
sub-batches of damage before a rate could fire. Resilience4j can use a constant
minimumNumberOfCalls because a breaker sits on an unbounded call stream; a batch
indexer has a finite budget, so a constant can exceed the whole run.

The ratio is still evaluated only inside the catch. That is already its local
maximum — both counters have just incremented — so sampling more often would
only ever observe lower ratios.

Also: a failing cleanup DELETE no longer swallows the abort, which was
discarding the retained first-error-of-the-streak that names the real endpoint
fault; `ceilingError` is renamed `abortError` since it carries the ratio abort
too; and three `{ error }` log keys become `{ err }` (#2114 — an arbitrary key
serializes to `{}`, losing message and stack).

* fix(analyze): one tri-state embedding counter, and stop partial runs wedging later runs

The tri-state count doctrine this branch introduced was applied at two of its
three CLI sites, and the two implementations that were meant to mirror each
other had already drifted.

`measurePersistedEmbeddingCount` moves to `core/embedding-count.ts` — beside
`embedding-mode.ts`, with the same no-native-imports property, and outside
`core/embeddings/` so the lazy-embeddings convention (#2370) still holds. All
three call sites now share it.

  - The mid-run `onCheckpoint` counter ran the query bare. A throw there — DB
    busy, connection closed, read-only, the VECTOR DML lock (#2623) — rejected
    the callback out of `runEmbeddingPipeline` and killed the analyze before
    Phase 5 could apply the tri-state that exists for exactly this case. A
    non-numeric cell wrote `stats.embeddings: null` to disk mid-run.
  - Phase 5 used `?? 0` while the server used `?? Number.NaN`, under a comment
    asserting both measured the field the same way. `Number.isFinite(0)` is
    true, so a no-row answer became a *measured* zero and hard-failed a run
    whose embeddings had all persisted.
  - The unknown-count fallback read `existingMeta`, assigned once at run start,
    so it republished the pre-run figure over the fresher count the terminal
    checkpoint had already written. With a prior count of 0 that armed the wipe
    chain: hasExisting false, shouldLoadCache false, and the next --force
    discards live embeddings. It now re-reads the latest on-disk meta, and an
    unverifiable count retains a recovery marker instead of clearing it.

A completed-but-partial run also planted a landmine. Its checkpoint is stamped
with the run's embedding identity, so a later plain `gitnexus analyze` from a
hook, a CI job, or a shell without GITNEXUS_EMBEDDING_URL resolved provider
'local' and threw before any phase ran — after an exit-0 run, where previously
only a visible crash left that state. `--force` did not help: the resume gate
inspected only `--drop-embeddings`.

`RepoMeta.embeddingCheckpoint` gains `kind` to tell the two situations apart.
An 'interrupted' marker (or one with no kind, so markers already on disk keep
the stricter path) still fails closed — its nodes may be half-written, and
resuming under a foreign model would mix vector spaces. A 'partial' marker
names nodes the pipeline already deleted to zero rows, so nothing is at risk: an
identity mismatch drops the pending set with a warning and continues. `--force`
now discards a checkpoint, and `attempts` bounds the retry at
EMBEDDING_RESUME_MAX_ATTEMPTS (3, matching the HTTP embedder's and the WAL
driver's existing per-operation budgets) so a node the endpoint deterministically
rejects converges instead of keeping the repo incomplete forever.

* fix(server): close the SSE stream on terminal job status, not a progress phase

A tolerated partial run reached SSE clients as a clean success — a regression in
this branch's own claim that /api/embed reports a partial run as failed.

The pipeline emits `phase:'ready'` unconditionally before returning, including
when it dropped nodes. The route mapped that to `'complete'`, and
`mountSSEProgress` treated a terminal-looking *progress phase* as terminal:
write the event, `res.end()`, `unsubscribe()`. The route's own
`updateJob({status:'failed'})` then fired into a stream with no listener, and
the web app had already shown "ready". Before this branch the pipeline threw,
which produced `phase:'error'` and did reach the client. Pollers on
GET /api/embed/:jobId were unaffected, so the two consumers disagreed.

Terminality is a property of the job, so the relay now asks the job. Remapping
`ready` alone would have left the trap armed: the `error -> 'failed'` mapping
has the identical shape and would emit `event: failed` with `error: undefined`
before the catch block fills the message in. `ready` is additionally remapped to
`finalizing` so a poller no longer sees `status:'analyzing'` next to
`progress.phase:'complete'`. The single-terminal-event property (#2264) is
preserved on both the clean and partial paths, and /api/analyze is unaffected —
its terminal progress phase is 'done', never 'complete'.

`AnalyzeJob` gains an optional `partial` payload so a client can tell a partial
run from a total failure without a new status member; it is absent on every
other job, so existing payloads stay byte-identical. Consuming it in
gitnexus-web is left to that app's owner — today it renders both as the same
red retry chip.

`resolveEmbedRunOutcome` moves to `embed-run-outcome.ts` and `mountSSEProgress`
to `sse-progress.ts`, both free of Express/LadybugDB/MCP imports, and the local
count copy is replaced by the shared `core/embedding-count.ts`. Reaching three
pure functions previously meant importing the whole server: measured at ~20s
against a 30s test timeout, with one observed timeout failure. That file is now
1.6s.

* docs: document the partial embedding index and its recovery

A run can now finish exit 0 with a partial embedding index, which neither
operator doc described.

GUARDRAILS' "Embeddings vanished after analyze" Sign keys its trigger on
`stats.embeddings` being 0 and lists "the only ways to end up at zero". A
partial run stamps an honest non-zero count and sets `embeddingCheckpoint`, so
the operator's actual symptom is `incompleteReasons:
["embedding-checkpoint-pending"]` — a state that Sign cannot match. Adds a Sign
for it and drops the exhaustive framing from the existing one.

RUNBOOK gains the recovery path: a plain `gitnexus analyze` is correct and needs
no flag, because a retained checkpoint forces generation for the pending nodes
regardless of flags. Also corrects two stale claims — that `stats.embeddings` is
always freshly measured (it can carry forward when the count query cannot
answer, which is why `capabilities.vectorSearch.status` is the certified read),
and that later analyzes must always pass `--embeddings` or lose their vectors,
which contradicts Non-negotiable 5.

* refactor(embeddings): one owner for the checkpoint record and the abort predicate

Cleanup pass over the #2790 review fixes. No behavior change except where
noted; the two exceptions are both cases where the code was lying to the
operator or to the other half of itself.

The previous pass extracted `core/embedding-count.ts` because two hand-copied
bodies of "measure the embedding count" had drifted inside a single change. It
then created a second pair of hand-copied publishers — of
`RepoMeta.embeddingCheckpoint` — and those had drifted too: the CLI armed the
attempt counter only after clearing its identity gate, the server derived it
from the resumed marker alone. Only one of the two READERS implemented `kind`
at all, so a 'partial' marker written by `gitnexus analyze` and resumed through
POST /api/embed still hit the permanent wedge `kind` exists to remove.

`core/embedding-checkpoint.ts` now owns the record: `checkpointKind` (the one
home for absent-means-interrupted), the three minters, `nextAttemptCount`, and
`decideEmbeddingResume`, which both gates route through. Five mint sites and
two resume gates become one implementation each.

`resilient-fetch.ts` exports `isTerminalNetworkError` and `classifyOutcome`
calls it, replacing a caller-side copy of the same DOMException test whose
docstring promised it "mirrors classifyOutcome exactly" — an invariant enforced
by prose, where a divergence silently reverts body-phase timeouts to being
retried three times and charged to the shared breaker.

The ratio-guard floor now divides by the run's actual `subBatchSize` instead of
a constant 16 that assumed the default of 8. At `subBatchSize: 32` the old
formula demanded more sub-batches than the run contains, leaving the guard
structurally off — the exact failure the scaled floor was introduced to fix,
and sub-batch size is tuned mainly for the flaky endpoints it protects.

Two operator-facing corrections:

  - The count-recovery marker was stamped `kind: 'partial'` with an empty
    pending set, so `gitnexus status` reported "N node(s) lost their embeddings"
    where N is zero. It gets its own kind and its own incomplete reason.
  - `decideEmbeddingResume` initially keyed its skip-the-identity-gate branch on
    an empty pending set, assuming that meant the count-recovery marker. It does
    not: `onCheckpoint` mints an 'interrupted' marker with no pending nodes
    after every post-window save. That silently cleared an interrupted marker
    under a foreign provider instead of failing closed. Keyed on `kind` now,
    with a regression test.

Also: `isTerminalJobStatus` adopted at the seven sites that still hand-copied
it, including the one gating the single-terminal-event emit; `mountSSEProgress`
re-export dropped and `server-sse-payload.test.ts` repointed at the extracted
module, which takes it from 24.60s to 0.408s — the test that motivated the
extraction was still paying the cost it was meant to remove; the count-mismatch
message and the SSE test harness deduplicated; per-batch error strings made
lazy (~75k needless `new URL()` per large run); `retryable: true` dropped as a
field that can never be false; ~110 lines of restated rationale reduced to
pointers at their canonical home.

fix(scope-resolution): a closure binding is a call SOURCE in every language, and function-local values carry their own identity (closes #2699) (#2718)
* test(scope-resolution): audit the consumers of file-scoped node ids (#2699 part A)

#2699 item 4 — "audit consumers that assume file-scoped ids" — after #2695/#2714
gave function-local CALLABLES position-bearing ids. Tests and findings only; no
production change. That split is deliberate: `impact` reports
`resolveDefGraphId` at CRITICAL with 23 DIRECT dependents across 7 modules
(every language MRO builder, both Spring attachers, C++ member lookup,
tryEmitEdge, emitReferencesViaLookup, buildGraphTargetIndex, emitFreeCallFallback,
emitReceiverBoundCalls, preEmitInheritanceEdges, emitDetectedInterfaceImplementations,
phpEmitUnresolvedReceiverEdges, emitRubyMixinEdges, emitRustTraitImplEdges,
emitDartHeritageEdges), so changing that key chain is its own change, not a
rider on an audit.

A2 — detect_changes: CONCERN RESOLVED, now pinned. The worry was that an id
containing `@row:col` re-keys whenever a declaration MOVES, making every edit
look like symbol churn. It cannot: `local-backend.ts` maps diff hunks to
symbols by LINE-RANGE OVERLAP (`n.startLine`/`n.endLine`) and merely REPORTS
`n.id`. Node identity never participates in the match. New structural test
asserts the WHERE clause never gains `n.id =` or `n.id IN`, keeps the one
legitimate id-shaped predicate (the `BasicBlock:` prefix exclusion, #2082 U7),
and confirms the id is returned rather than matched. Structural in the same
idiom as `detect-changes-worktree.test.ts`, and labelled as not proving runtime
behaviour.

A1 — ANSWERED, and the answer is that #2699 is NOT fully closed by items 1-3.
The fail-closed guard is gated on `isOverloadableCallable`
(Function | Method | Constructor), so a function-local VALUE never reaches it.
Measured on a fixture: a top-level `const handler` and a function-local
`const handler` still produce ONE node, `Const:v.ts:handler`. That is the
residual half of the issue's original complaint. Pinned as a KNOWN LIMIT with
its reason (widening identity to values re-keys ~14,700 build-time nodes to
change ~800 persisted ones — the decision recorded in `parse-worker.ts`), and
deliberately NOT fixed here.

A3 — id-persisting consumers, classified:
  - detect_changes ................ SAFE (position-keyed; pinned by A2)
  - MCP impact/context/trace ...... SAFE (resolve by name/uid at query time)
  - bench fingerprints ............ SAFE (digest capture shape, not node ids)
  - rust-captures golden .......... SAFE (digests captures, not ids)
  - cfg pipeline-pdg snapshot ..... AT RISK by design — pins exact edge ids, so
    it trips whenever attribution changes. That is the gate working; #2714
    already exercised it.
  - wiki / group-contract links ... NOT id-keyed on locals (locals are never
    cross-file addressable, per the document-scoped contract of item 2).

Verified: tsc clean; 14/14 across the two touched files; `detect_changes`
reports 0 changed symbols (tests only).

Claude-Session: https://claude.ai/code/session_0184RmD24KFJidYqpM7v3XjR

* fix(php): a closure binding is a call SOURCE, not only a TARGET (#2699 part B, S1)

A call made inside a closure binding was attributed to the ENCLOSING scope, so
the closure was a call TARGET but never a call SOURCE: impact(handler,
direction:"downstream") reported nothing even though the closure calls out.

Root cause, probe-measured rather than inferred. Instrumenting
pickCallerCallableDef (graph-bridge/ids.ts) to log every rejection reason shows
the closure's own scope EXISTS and its range DOES contain the call site, but its
ownedDefs is EMPTY, so the ":94" owned-callable filter drops it and attribution
falls through to the ":97" enclosing-scope fallback.

The reason is one missing query rule. javascript/query.ts pairs the binding name
with the closure via @declaration.function anchored on the INNER arrow node, so
anchor.range equals the @scope.function range and pass2AttachDeclarations
attaches the declaration to the CLOSURE's scope. No other language had that
rule — PHP, Rust, Kotlin, Ruby and Dart all captured named function
declarations only. That single omission is the entire empty-ownedDefs cause.

This ports the rule to PHP with the same anchor discipline (@declaration.function
on the inner anonymous_function / arrow_function, NOT on the
assignment_expression wrapper). PHP needs nothing else: it already declares
(anonymous_function) and (arrow_function) as @scope.function, so the rule alone
completes it.

Measured on a fixture: `$handler = function ($x) { return target($x); }` inside
outer() now emits

  Function:src/a.php:outer.$handler@3:2 -> Function:src/a.php:target

where it previously emitted `outer -> target`.

The pinned test in closure-binding-labels.test.ts asserted the OLD, wrong
behaviour by design ("to catch that asymmetry changing in EITHER direction"), so
it is INVERTED here rather than deleted, per its own instruction. Its block
comment is corrected to record the measured root cause, including that Kotlin
and Ruby will need BOTH this rule AND a relaxed kind gate (their lambda_literal
/ do_block is @scope.block deliberately, #1757), and that Dart has no closure
scope at all.

Verification: closure-binding-labels 50/50; PHP resolver suites 221/221
(php, php-coverage, php-response-shapes). detect_changes {staged}: 1 changed

* fix(rust): emit a node for a closure binding and make it a call SOURCE (#2699 part B, S3)

Rust was the one exception to #2687's "a closure bound to a name is a Function
node in every language": `let handler = || target(1);` produced NO graph node at
all, so the closure could be neither a call target nor a call source.

Needed BOTH query channels, which is the finding worth recording. Porting only
the scope-resolution rule (as S1 did for PHP) changed nothing measurable here,
because there was no node to attribute anything to:

  - languages/rust/query.ts — closure-binding declaration, @declaration.function
    on the INNER closure_expression so anchor.range aligns with the existing
    (closure_expression) @scope.function. This is what gives the closure's own
    scope a callable in ownedDefs, which is what stops pickCallerCallableDef
    falling through to the enclosing fn.
  - tree-sitter-queries.ts — @definition.function on the OUTER let_declaration.
    This emits the Function NODE that Rust never had.

Note the deliberate anchor asymmetry between the two channels: the graph-node
channel anchors the WRAPPER (matching the existing
(lexical_declaration (variable_declarator ... (arrow_function))) rule), while
the scope-resolution channel anchors the INNER closure (to align with
@scope.function). Getting these backwards silently produces either no node or
an unattributable one, so both sites carry a comment saying so.

Measured on a fixture — `let handler = || target(1);` inside outer():

  Function:src/a.rs:outer                CALLS  Function:src/a.rs:outer.handler@2:4
  Function:src/a.rs:outer.handler@2:4    CALLS  Function:src/a.rs:target

Previously the whole binding was absent and the call read as `outer -> target`.
The rule also covers `move` closures: the closure_expression node spans the
`move` keyword.

Verification: closure-binding-labels 50/50; rust.test.ts 192/192;
rust-coverage, rust-f70, rust-scope all pass; rust-captures-golden passes
UNCHANGED, so no golden regeneration was required. detect_changes {staged}:
2 changed symbols (RUST_SCOPE_QUERY, RUST_QUERIES), 0 affected processes,
risk LOW.

One caveat on the suite runs: this host times out `beforeAll` hooks at the
default 60s under load — rust.test.ts needed --hookTimeout=600000 to complete,
and a concurrent second vitest run starves worker startup entirely (every test
fails at ~5001ms). Both are host artifacts, not signal.

* fix(kotlin,ruby): a closure binding is a call SOURCE, via a Block-scope callable boundary (#2699 part B, S2)

Kotlin and Ruby anchor a closure on a Block-kind scope — Kotlin lambda_literal
and Ruby do_block/block are @scope.block DELIBERATELY (#1757 smart casts), so
they must not be re-kinded. pickCallerCallableDef gated its child-scope walk on
kind === 'Function', so a closure there could never become a call SOURCE.

Both halves are required; neither alone changes anything:

1. kotlin/query.ts and ruby/query.ts gain the closure-binding declaration rule,
   with @declaration.function on the INNER lambda_literal / block so its range
   aligns with the @scope.block range (the anchor discipline documented in
   javascript/query.ts). Without this the closure scope owns no callable def.

2. pickCallerCallableDef accepts a Block-kind child as a callable boundary when
   the scope IS that callable's body. Without this the kind gate still rejects.

The alignment test in (2) is the part worth scrutiny. Relaxing the kind gate to
accept ANY Block owning a callable would be a real regression: a nested
`fun foo()` declared inside a block is owned by that block, so a call made at
BLOCK level — outside foo — would be misattributed to foo. Comparing the def's
declaration position against the scope's start position discriminates them: for
a closure the declaration and the scope sit on the SAME node, so the positions
match; for a nested function the block starts at `{` while the def starts at the
declaration, so they do not. Existing Function-kind behaviour is untouched, so
every already-working language is unaffected by construction.

The comparison is base-safe: scope-extractor.ts builds a def id as
`def:<filePath>#<startLine>:<startCol>:<type>:<name>` from the same Range a
scope carries, so both sides share one coordinate base. This is called out in
the helper's docblock because `defStartLine` nearby documents its own output as
1-based, which invites a wrong "fix" (#2377 is exactly this class of hazard).

Ruby's call forms are restricted to lambda/proc by name: an unrestricted
(call block: (block)) would match ANY method call taking a block, so
`mapped = items.map { |i| ... }` would wrongly declare `mapped` a callable.
Verified against the parser: 3 matches (->, lambda, proc), map excluded.
Separate #eq? patterns rather than one #match? alternation, which is a known
hazard on this tree-sitter line.

Measured on fixtures:

  Kotlin  Function:src/A.kt:outer.handler@2:4  CALLS  Function:src/A.kt:target
  Ruby    Function:src/a.rb:outer.handler@4:2  CALLS  Method:src/a.rb:target#1

previously `outer -> target` and `outer#0 -> target#1`.

The pinned Kotlin test asserted the old behaviour by design and is INVERTED, not
deleted. Ruby had NO pinned case, so a new one is added rather than inverted.
The describe title no longer claimed something false ("not yet a call SOURCE"
now holds only for Dart) and was retitled.

Verification: closure-binding-labels 51/51; kotlin.test.ts, kotlin-coverage,
ruby.test.ts, ruby-scope, ruby-namespaced all pass (478 passed / 1 expected
inversion before the test was flipped). impact on pickCallerCallableDef:
CRITICAL, 191 impacted, ONE d=1 (resolveCallerGraphId) — the return contract is
unchanged, so that dependent is unaffected. detect_changes {staged}: 5 changed
symbols, 2 affected processes (both EmitReferencesViaLookup, one of them the new
ScopeIsCallableBody step), risk medium.

Dart remains the last failing language: dart/query.ts declares no
@scope.function at all, and dart/captures.ts synthesizes one only from a
declaration WITH a body node, which an expression-bodied closure lacks.

* fix(dart): give a closure binding a scope and a distinct identity (#2699 part B, S4)

Dart was the last language where a closure binding could not be a call SOURCE,
and fixing only that would have made the graph WORSE, not better. This lands
both halves together for that reason.

## The attribution half

A Dart closure had no scope at all. `dart/query.ts` declares no
@scope.function anywhere — Dart's function scopes are SYNTHESIZED in
`dart/captures.ts` from `declNode` + `findFunctionBody(declNode)`, and
`findFunctionBody` looked only at the next named SIBLING for a `function_body`.
A closure literal carries its body as a CHILD (`function_expression_body`), so
it matched nothing and no scope was produced.

`query.ts` gains the closure-binding declaration rule and `findFunctionBody`
understands the child form. Deliberately NO @scope.function is added to the
query: it would collide at identical range with the synthesized one, and
duplicate scope ids make `buildScopeTree` throw, which DROPS THE WHOLE FILE.

## The identity half, and why it is not optional

With attribution alone, two same-named closures in one file both keyed to the
bare `Function:a.dart:handler`. One node then appeared to call BOTH targets —
a CALLS edge present nowhere in the source. That is worse than the missing edge
it replaced, so S4 could not ship without this.

Root cause is not Dart-specific. `enclosingCallablePrefix` derives a SEMANTIC
relation — what encloses this callable — by SYNTACTIC ancestor walk. Dart parses
`int outer() { … }` as `function_signature` followed by `function_body` as
SIBLINGS, so the enclosing callable is never an ancestor of code inside it and
no membership set can fix that; the walk looks in the wrong direction.

This is what SCIP and real compilers avoid by construction. SCIP keeps a local
symbol opaque (`local <id>` — no name, no position, no chain) and models
containment as a SEPARATE `enclosing_symbol` field; its spec says the local/global
choice should follow ACCESSIBILITY, not the ability to name an enclosure. Dart's
own analyzer answers this from `Element.enclosingElement` in the element model,
never from AST ancestry. clang uses `name@offset` for a function-local; Kythe
uses a document-scoped VName plus a `childof` edge. Identity is positional and
opaque; enclosure is a relation.

`findSplitBodyCallableAncestor` is the narrow fix at that seam: a fallback used
ONLY when the ancestor walk finds nothing, recovering the callable from the
body's preceding sibling.

The sibling must be a BARE SIGNATURE, and that restriction is load-bearing —
"any preceding callable sibling" is WRONG and was caught regressing PHP during
this work. In `<?php function target($x) {…} $handler = function ($x) {…};` the
closure is at FILE level, so the ancestor walk correctly finds nothing, the
fallback runs, and an unrestricted version mis-qualified the file-level
`$handler` as `target.$handler`. A preceding sibling is only an ENCLOSING
callable when it cannot hold its own body.

`SPLIT_SIGNATURE_NODE_TYPES` is exactly that set and is DERIVED, not listed:
`LOCAL_SCOPE_BODY_NODE_TYPES` is already `FUNCTION_NODE_TYPES` minus the bare
signature types, so the difference between them IS the split-signature set
(`function_signature`, `method_signature` — verified at runtime). PHP's
`function_definition` carries a body and is in both, so it is excluded. No
language is named in shared code, and any future split-grammar language is
covered for free.

## Verification

Full resolver sweep — the gate that caught #2714's Rust regression — 2926
passed / 1 skipped / 0 failed across 51 files. closure-binding-labels 52/52;
dart.test.ts, dart-coverage, callable-id-lockstep, function-local-identity,
caller-identity-regression all pass (156/156 across 6 files).
impact on `enclosingCallablePrefix`: LOW, 5 impacted, 3 d=1 all inside
parse-worker. detect_changes {staged}: 5 changed symbols, 0 affected processes,
risk LOW.

Three existing Dart expectations FLIPPED rather than being deleted: Dart locals
now carry the same enclosing-callable + position identity every other language
got in #2695, so `local.dart:handler` became `local.dart:caller.handler@1:2`.
A new test pins the actual defect — two same-named closures staying DISTINCT
nodes — because the qualification assertions alone would not fail if the
fabricated edge returned.

One note for future work: an id-shape assertion here carries a call-site suffix
on indirect invocations (`…handler@3:2:5:9`) but not on direct calls. That is
the callable-value-flow pass keying its edge by invocation position, not part of
the node id.

Part B is now complete: PHP (S1), Rust (S3), Kotlin + Ruby (S2), Dart (S4).

* fix(scope-resolution): close every deferred item on #2699 (A1 values, twin-list guard, schema bumps)

Clears the limitations this PR had been carrying rather than leaving them as
follow-ups.

## A1 — function-local VALUES now carry their own identity

This was #2699's ORIGINAL complaint and the one a callable-only gate could never
reach: a top-level `const handler` and a function-local `const handler`
collapsed onto ONE `Const:v.ts:handler`. #2695 restricted position-qualified
identity to Function|Method|Constructor because the collision that produced
wrong CALLS edges was between callables, and widening churned ids for symbols
the pruner mostly deletes. The churn is real and is accepted here deliberately.

Widening needed THREE gates aligned, not one:
  - id-building     — `parse-worker.ts` nestedCallablePrefix
  - resolution      — `ids.ts` position key
  - registration    — `node-lookup.ts` position-key registration

Missing the third would register no position key for values, so every lookup
misses and falls through silently. That is the #2714 failure mode: the caller
attaches to a node that does not exist and the edge is DROPPED, which looks like
"zero dangling edges" from outside. All three now route through ONE predicate,
`isPositionQualifiedLocalLabel`, rather than repeating the label set a third
time.

Only LOCALS move. The prefix comes from `enclosingCallablePrefix`, which returns
undefined when nothing encloses the declaration, so top-level and class-member
ids are untouched — verified by the full resolver sweep, where a leak onto class
members would have broken assertions in every language. `Property` is included
on purpose: a class field stays unqualified because the prefix walk boundaries
on class-likes, while an object-literal property inside a function is genuinely
local and would otherwise keep the old collision.

Measured: `Const:v.ts:handler` + `Const:v.ts:run.handler@3:2`, two distinct
nodes. The KNOWN LIMIT test is FLIPPED per its own former instruction ("this
test should be updated as part of it rather than deleted").

## Schema bumps — required by Part B, not just by A1

INCREMENTAL_SCHEMA_VERSION 20 -> 21, parse-cache SCHEMA_BUMP 27 -> 29.

SCHEMA_BUMP is 29, not 28, and that is the point of re-checking it against
origin/main at MERGE time rather than branch time. This branch cut at 27 and
bumped to 28; #2415 also bumped 27 -> 28 and merged first. The automated
main-merge onto this branch surfaced the collision — leaving it at 28 would have
shipped this whole change with NO parse-cache invalidation, so every warm cache
keeps replaying the pre-fix captures and ids. This is the third instance of that
collision recorded in parse-cache.ts (#2632/#2653 hit it at v21, and
#2653/#2654 hit INCREMENTAL_SCHEMA_VERSION the same way).

Part B already changed emitted node ids AND edges on files that did not
themselves change (Dart locals re-keyed, Rust gained a node it never emitted,
five languages gained closure-source attribution). A v20 index topped up
incrementally keeps serving the old attribution, and a warm parse cache replays
the old captures and ids verbatim. Shipping S1-S4 without these would have let
every existing index silently keep the pre-fix graph.

## Twin-list drift guard — the sixth instance in this family

`IMPLICIT_RECEIVERS` (gitnexus-shared lookup-core.ts) and `THIS_RECEIVERS`
(type-env.ts) spell the same concept in two packages, and nothing enforced
agreement — `$this` was added to the shared list in #2714 only because it was
already in the other. New structural test asserts set equality plus the ONE
deliberate asymmetry (`Me`, Visual Basic spelling, absent from the shared list
because no SupportedLanguages entry uses it) in BOTH directions, so re-adding it
there or dropping it here each fail loudly.

Structural rather than value-imported: both constants are module-private, and
exporting them purely to be testable would widen two public surfaces to satisfy
a test.

## Two false comments corrected

  - `lookup-core.ts` said "see the drift guard noted in #2714", implying a guard
    existed when it was only a deferred follow-up. It exists now, and the
    comment points at it.
  - `callable-id-lockstep.test.ts` claimed its regex "fails if any site
    reconstructs the id". It matches ONE template spelling; a hand-rolled
    concatenation still slips past. Now stated as a tripwire for the known
    shape, not a proof.

## Skill learnings

Four entries appended to eval/workflow_bench/learnings.jsonl from this run: the
v9fs safe-writer failure, backticks silently terminating a query template
literal (hit three times), a module-level TDZ const that passes tsc and then
presents as N file failures with ZERO failing assertions, and concurrent vitest
runs starving worker startup so a whole suite fails at ~5001ms.

## Verification

Full resolver sweep 2926 passed / 1 skipped / 0 failed (51 files) — identical to
pre-A1, which is the evidence that only locals moved. All EIGHT bench gates PASS
with fingerprints UNCHANGED, so no regeneration was needed. function-local-identity,
callable-id-lockstep, receiver-twin-list-drift and closure-binding-labels 71/71.
tsc --noEmit clean.

detect_changes {staged}: 9 changed symbols, 14 affected processes, risk HIGH —
expected, and the reason the sweep above is the gate rather than a targeted list.
Every affected process routes through `resolveDefGraphId`, the key chain Part A
measured at CRITICAL with 23 direct dependents.

Deliberately NOT done: the SCIP end state (opaque `local <id>` plus an explicit
enclosure EDGE instead of containment encoded in the id string). It is a design
direction, not a limitation of this work, and it is INCOMPATIBLE with A1 — A1
widens chain-encoded identity, that removes chain encoding entirely. Bundling
both would re-key every local twice. Written up in the research notes.

* test: update two assertions the #2699 changes correctly invalidated

Both failed on CI at da3d8397 and are fixed here. Neither is a behaviour
regression; both pinned values that this PR deliberately changed.

1. this-boundary.test.ts — "a Kotlin lambda still sees the receiver"

The `this.m()` edge still exists and `this` still resolves to the enclosing
receiver, which is the ONLY property this test exists to guard (its own comment
said so: "what matters here is only that the `this.m()` edge still exists at
all"). Only the SOURCE moved, from `run` to the lambda:

  Method:K.kt:K.run#0       -> Method:K.kt:K.run.f@2:16
  Method:K.kt:K.run.f@2:16  -> Method:K.kt:K.m#0

The comment justifying the old expectation is now false and is corrected rather
than left: it said the lambda "is not its own caller anchor" because Kotlin
scopes `lambda_literal` as a BLOCK. Kotlin still scopes it as a block (#1757 is
unchanged) — what changed in S2 is that a Block-kind scope is accepted as a
caller anchor when the scope IS the callable's body.

2. call-summary-schema-version.test.ts — INCREMENTAL_SCHEMA_VERSION pin

Moves 20 -> 21 with the bump, which is the point of pinning it: a change that
alters emitted ids or edges without bumping would otherwise ship silently.

Also adds the missing reuse-gate case. `passesReuseGate(20)` now asserts FALSE —
a v20 index predates closure bindings becoming call SOURCES, the Rust node for
`let f = || …`, the Dart closure scope + enclosing-callable identity, and
position-qualified function-local values. Topping such an index up incrementally
keeps serving the old attribution, including the Dart case where two same-named
closures collapsed onto one node and asserted a CALLS edge present nowhere in
the source.

Why CI found these and local verification did not: the verification set was
`test/integration/resolvers/` plus a hand-picked list, and both failures sat
outside it — one integration test about `this` (which a caller-attribution
change obviously touches) and one unit test pinning the exact constant that was
bumped. Grepping for the changed constant, and for tests asserting closure
attribution, would have found both. All 8 suites that reference the schema
constants were then run: 177/177, no third pin.

Verification: this-boundary + call-summary-schema-version 17/17;
the 8 schema-referencing suites 177/177. detect_changes {staged}: 0 changed
symbols, 0 affected processes, risk LOW (assertion-only edits).

* fix(scope-resolution): resolve every finding from the multi-engine review of #2699 part B

The first cut of Part B shipped four P1 defects. A two-engine review (Claude
swarm + ce personas; Codex gpt-5.6-sol swarm + ce + adversarial) found all four,
three of them because an independent engine disagreed with the authoring one.
Each is fixed here and pinned in test/integration/closure-review-findings.test.ts.

## P1-1 — a multi-line closure binding fabricated a CALLS edge

The worst of the four, because it reintroduced the exact defect class #2699
exists to remove. The two query channels anchor on DIFFERENT nodes by design
(graph-node on the outer wrapper, scope-resolution on the inner closure) and the
bridge joins them on line only. Same line, the join matches. Split across lines:

    $multi =
        function ($x) { return target($x); };

the join missed, `resolveDefGraphId` failed closed, and `resolveCallerGraphId`
then CLIMBED to the parent scope — emitting `outer -> target` although `outer`
calls nothing, while the real `outer.$multi` node sat with zero outgoing edges.

`resolveCallerGraphId` now fails closed at the owning callable instead of
climbing. If we have identified the callable that owns a call site and cannot
name its graph node, crediting an ancestor is not graceful degradation — it
invents a relationship. A missing edge is the correct failure direction for a
graph whose consumers include `impact`.

Getting there took two attempts, worth recording: the first guard keyed on the
def's qualifiedName carrying the `@line:col` local marker, but that suffix is
added by parse-worker for GRAPH NODE ids and scope-resolution defs do not have
it, so the guard never fired. `pickCallerCallableDef` now reports whether the
callable came from a child scope, and the fail-closed applies to the owning
callable either way.

## P1-2 — TS constructor parameter properties were re-keyed as locals

A REGRESSION against the base, not merely an incomplete fix. Admitting
`Property` to the position-qualified set made the enclosing-callable walk reach
the constructor's `method_definition` THROUGH the parameter list — a
LOCAL_SCOPE_BODY hit that lands before any class boundary — so
`constructor(private readonly port: Port)` produced
`Property:svc.ts:Service.constructor.port@2:14` instead of `Service.port`. That
silently empties the slot `impact`, `rename` and FTS address while the class
still asserts HAS_PROPERTY against it, and it is the Angular/NestJS DI idiom.
A real instance exists in this repo at src/core/group/service.ts:304.

parse-worker.ts already computed the correct exemption (`isFunctionLocalProperty`,
lines 2245-2257) two lines above; the new ternary discarded it. Now reused, so
the owner-edge decision and the id decision cannot disagree.

## P1-3 — Dart top-level and `final` closures were never call sources

The rule matched only `initialized_variable_definition`, Dart's FUNCTION-LOCAL
shape. A top-level `var` is `initialized_identifier` and a top-level
`final`/`const` is `static_final_declaration`; the second declarator of
`var f = ..., g = ...` is also `initialized_identifier`. None got a declaration
capture, so `findFunctionBody` never synthesized their scope.
dart/captures.ts ALREADY listed all three in bindingNodeTypes for callable-flow
— the declaration rule simply did not mirror it. It does now.

## P1-4 — Ruby `do ... end` and `Proc.new` closures were uncovered

`do ... end` is the dominant MULTI-LINE Ruby style and produces `(do_block)`;
all three patterns matched `(block)` only. The scope channel already covered
both, so these closures got a Block scope owning nothing and their calls fell
through to the enclosing method. The PR's own Ruby test used the brace form, so
it passed.

Fixing it needed BOTH channels — tree-sitter-queries.ts had no graph-node rule
for the `(call)` forms either, exactly as Rust did. Verified: brace, do/end and
Proc.new are now all sources.

## Also from the review

- The split-signature fallback could fire on VALID TypeScript: a
  `declare namespace` containing a bodyless overload made the next declaration's
  `export_statement` a sibling of a `function_signature`, so `send` became
  `internalHelper.send@2:9`. The fallback now requires the matched node to be
  the signature's BODY (a body holds statements; a declaration wrapper holds
  another signature), which separates the two without naming a grammar.
- `isCallableDef` re-spelled `Function | Method | Constructor` in the same file
  that imports `isOverloadableCallable` and calls it three times — a NEW twin
  list, in the PR whose headline is a twin-list drift guard. It now delegates.
- A partial edit had left a self-contradictory comment in parse-worker.ts
  ("Restricted to CALLABLE labels: the / Applies to VALUES as well as callables").
- eval/workflow_bench/learnings.jsonl carried a "skill": "gitnexus-plan" entry,
  but that skill's SKILL.md:347 states feedback is chat-only and forbids
  appending learnings during a planning task. Dropped; the three gitnexus-work
  entries are sanctioned and stay.
- Ruby's lambda/proc patterns tested the method NAME only, so `MyMod.lambda { }`
  was captured as a closure binding. `!receiver` now constrains them.
- Rust's closure work (S3) had ZERO test coverage anywhere — verified once by a
  throwaway fixture and never pinned. Now covered.

## Verification

Full resolver sweep plus the identity/closure suites: 3017 passed / 1 skipped /
0 failed across 58 files (up from 2997 — the new tests). This is the gate that
mattered for P1-1: failing closed instead of climbing could have silently
deleted real edges in any language, and ~2900 resolver assertions say it did
not. All EIGHT bench fingerprint gates PASS with fingerprints UNCHANGED.
tsc --noEmit clean.

detect_changes {staged}: 14 changed symbols, 18 affected processes, risk
CRITICAL — expected, since P1-1 changes the fallthrough of `resolveCallerGraphId`,
the key chain Part A measured at CRITICAL with 23 direct dependents.

* fix(scope-resolution): a named receiver's member never resolves lexically (#2699)

`lookupCore` Step 1 walked the lexical scope chain for every lookup, including
explicit-receiver property reads. So `options.baseUrl` could bind to an
unrelated function-local `const baseUrl` in the same file, and
`config.extractVisibility(node)` to the enclosing class's own method.

This is the residual half of the defect JS/TS block scopes narrowed in #2695.
Blocks moved nested-block locals off the chain of a reference outside the
block, which removed 114 false edges; a local declared directly in the function
body stayed on it, and no amount of extra scopes reaches that case. Fixed at
the cause instead: `recv.name` names a member of whatever `recv` denotes, so a
binding of the bare tail name in an enclosing scope is never the right answer.
Steps 2 and 3 (receiver type / owner members) are the legitimate routes.

`this` and `self` are EXEMPT, and that exemption was measured, not assumed.
Skipping Step 1 for every explicit receiver removed 711 edges on a 762-file
corpus — but 2 of those were genuine: `self.srcIx` and `self.streamedAt(...)`
after `const self = this`, reaching their own class's members through the
class-body scope. For a self-receiver the members and the lexical chain
legitimately overlap; for a named receiver they never do. Exempting the self
names keeps both true edges and still removes 709 false ones, adding none.

The removals were classified by reading source at the site, not by pattern-
matching ids — an "is the target a member of the source's owner?" heuristic
labelled 43 of them plausible and every one I then read was false:

    language = config.language;          -> the class's own `language`
    dirMap.get(...) / exactMap.get(...)  -> a sibling object-literal `get`
    return config.extractVisibility(n);  -> the class's own method (self-edge)
    writer.close();                      -> GraphEmitSink.close

Residual, deliberately kept: a `this.x` read can still bind lexically to a
same-named local. That is the price of the two true self-alias edges above.

`INCREMENTAL_SCHEMA_VERSION` 19 -> 20: a v19 index holds these false
CALLS/ACCESSES on every unchanged file and would keep serving them through the
reuse gate.

Test confirmed discriminating: it fails with the guard reverted.

* fix(typescript,javascript): a generator expression binding is a Function node (#2693)

`const g = function* () {}` matched none of the closure-binding definition
rules — they covered `arrow_function` and `function_expression` only — so the
binding emitted a `Const` node. `buildGraphTargetIndex` admits callable nodes
only, so `g()` resolved to nothing.

Same defect shape as the `var` case #2693 already fixed: a different grammar
node for the same construct, and the resulting graph node was not callable.

Adds the four variable-binding shapes in both languages: `const`/`let` and
`var`, each plain and exported. Purely additive — no existing pattern is
reordered or rewritten, because the #2687 pre-scan dedup is order-dependent
and collapsing the value/callable pair depends on which match wins.

Deliberately NOT covered, and the query comment says so: a generator in an
object-literal pair or a HOC wrapper still falls through anonymous. Those are
rarer, and each additional pattern is another chance to disturb the dedup.

`SCHEMA_BUMP` 26 -> 27: definition captures are parse-time, so a warm parse
cache would replay the old ones verbatim — `--force` does not clear it.

Two tests confirmed discriminating (they fail with the patterns reverted), plus
a guard that the already-working generator DECLARATION form is unaffected,
since it shares the emit path these were inserted beside.

* fix(ingestion): keep caller attribution in lockstep with definition ids (#2699)

The definition phase appends `localIdentity` to a nested callable's own name
segment (`run.save@3:2`); `findEnclosingFunctionId` did not, so the two phases
derived different ids for the same callable. The failure mode is silent — the
caller id names a node that does not exist, so the edge is dropped rather than
reported — which is why the parse-worker docblock calls this pair a lockstep
guarantee and asks that both phases derive the prefix from one place.

The condition is now byte-identical to the definition phase's
(`nestedPrefix !== undefined`), so the two cannot diverge again.

Scope of the claim, stated plainly: no reproducing case was found, and this
changes nothing measurable on a 762-file TypeScript corpus. TS/JS resolve
callers through `resolveCallerGraphId` in the graph bridge, not this path;
`findEnclosingFunctionId` serves the `callExtractor` languages, and the
corpus does not exercise a nested callable there. The review that raised it
(P3) observed zero dangling edges, and "zero dangling" is also what silently
dropped edges look like — so this closes a documented contract rather than a
demonstrated bug, and carries no test of its own.

Rides the `SCHEMA_BUMP` 26 -> 27 in the preceding commit: caller attribution
runs in the worker, so a warm parse cache would replay the old ids.

* docs(test): correct the block-scope header that this PR made false (#2699)

Review finding (MEDIUM). The file header still described `lookupCore` Step 1 as
walking the lexical chain for EVERY lookup, and called the function-body-local
case "unchanged and still mis-resolves ... pre-existing and tracked
separately". Commit 59b892ca in this same PR falsified both, and the describe
block added ~80 lines lower in this same file asserts the opposite — a reader
scoping future work from the header would have concluded the case was still
open.

Rewritten to state what the code does: Step 1 is skipped for a NAMED explicit
receiver, the function-body case is fixed here, and the surviving residual is
that a `this`/`self` read can still bind lexically to a same-named local —
with the reason those two names are exempt (they keep the genuine
`const self = this; self.member` reads that Step 1 resolves correctly).

Also corrects a PRE-EXISTING staleness inherited from #2695 in the same
paragraph block: "the genuine bare read of that same local must still emit its
edge" describes a test that no longer exists, because TypeScript emits no
`@reference.read` for bare identifiers at all. Fixed here rather than left
adjacent to a freshly corrected sentence.

Comments only — `detect_changes` reports 0 changed symbols across 1 file.

* refactor(ingestion): give the nested-callable id rule one definition (#2699)

Review finding (LOW): the lockstep change in this PR shipped without a test.
The plan called for a unit test asserting the two id-derivation phases agree.
Two things changed that plan during execution, both recorded here.

FIRST — there are THREE phases, not two. Re-verifying the plan's assumption
(`grep -n localIdentity`) found a third call site: the worker-path node-id
derivation in `processFileGroup` (parse-worker.ts:2316), whose own comment
already acknowledged the coupling. `impact` on `localIdentity` corroborates:
three direct dependents, all in the Workers module. So the invariant three
phases must agree on is now ONE function, `nestedCallableQualifiedName`, and
divergence requires deleting a call rather than editing a duplicated
expression.

SECOND — the planned `_forTest` alias seam does not work for this module.
`parse-worker.ts` posts a `ready` message to `parentPort` at module scope, so
value-importing it from a unit test throws before any test runs; the existing
unit tests that reference it use `import type` only, which erases. The rules
therefore move to a new pure module, `workers/callable-id.ts`. That is what
makes them testable at all, rather than merely commented.

Pure refactor — no id changes. Verified by the suites that assert exact node
ids (`Function:svc.ts:run.save@7:2`, `Function:c.php:run.$save@3:2`): 74/74
green, and `detect_changes` reports only the three expected symbols and the
two `processFileGroup` flows `impact` predicted.

The test pins both halves: the rule's contract, and a structural assertion
that no site has re-inlined `${prefix}.${localIdentity(...)}` — the unit
assertions alone would still pass if a fourth phase spelled the rule out by
hand, which is exactly how the divergence arose.

* fix(scope-resolution): give PHP's `$this` the same self-receiver exemption (#2699)

Review finding (LOW). The Step-1 skip added in this PR exempts `this`/`self`,
but the receiver name arrives as the reference node's RAW SOURCE TEXT —
`extractExplicitReceiver` returns `cap.text` verbatim — so PHP's `$this->x`
presents as the string "$this" and matched neither entry. PHP was the one
supported language whose self-receiver got no exemption at all.

Measured, and the measurement is why this is framed as consistency rather
than a bug fix:

  - Corpus delta ZERO. 762-file TypeScript corpus, CALLS+ACCESSES set diff:
    13179 -> 13179, added 0, removed 0. So no INCREMENTAL_SCHEMA_VERSION bump
    (stays 20), per the plan's decision rule.
  - No PHP shape found that DISCRIMINATES. Both the simple `$this->prop` /
    `$this->helper()` shapes and a closure reading `$this->…` inside a method
    that also declares a same-named local produce byte-identical edge sets
    with `$this` present and absent — Step 2 resolves the receiver's type
    first. The added test is therefore labelled a COMPANION INVARIANT, exactly
    as the `this.baseUrl` case beside it is, and does not claim to prove the
    fix.

It is still worth making: the exemption is protective, and the 709-removed /
0-true-lost measurement that justified the narrow guard was TypeScript-only,
so PHP's safety was never established by evidence. This closes that by
construction.

Two corrections to what the plan assumed, both found by checking:

  - The plan (and my first draft of this comment) claimed the codebase had no
    precedent for handling a sigil'd receiver name. FALSE: `THIS_RECEIVERS` in
    `core/ingestion/type-env.ts:244` has always listed `$this`, and it is the
    ingestion-side twin of this very list. The precedent does not merely
    exist, it validates the approach chosen here — list the spelling as data,
    do not strip sigils.
  - That twin also lists `Me`. Deliberately NOT mirrored: no entry in
    `SupportedLanguages` is Visual Basic, so it could only ever exempt a
    variable that happens to be called `Me`.

The two lists are otherwise the same set with nothing enforcing it — a fifth
instance of the twin-list drift class this PR keeps meeting. A drift guard is
the right fix and is out of scope here; noted for follow-up.

* fix(rust): resolve `Self` in scope-resolution type bindings (#2699)

CI regression, caught by `tests / ubuntu / coverage` on 13d5e738 and traced to
the named-receiver Step-1 skip earlier in this PR (59b892ca), not to the three
commits above it — verified by reverting those three and reproducing the
failure unchanged.

`test/integration/resolvers/rust.test.ts > resolves fresh.validate() inside
impl User via Self {} inference` failed: 192/192 on main, 191/192 on this
branch. The fixture calls `fresh.validate()` where `let fresh = Self { .. }`
inside `impl User` — a genuine call to `User::validate`, and a TRUE edge that
the skip deleted.

Root cause is a twin-channel disagreement, not the skip:

  - `type-extractors/rust.ts:142` substitutes `Self` -> the enclosing impl
    type into the TYPE-ENV channel via `findEnclosingImplType`.
  - `languages/rust/interpret.ts` recorded `@type-binding.type` verbatim, so
    the SCOPE-RESOLUTION channel bound `fresh: Self` — a type that does not
    exist, leaving the receiver's type unknown and Step 2 unable to resolve.

`main` passed only because Step 1 still walked the lexical chain for named
receivers: the impl scope binds `validate` by name, so the call resolved BY
ACCIDENT. Stopping that walk turned a latent gap into a lost edge. The fix
closes the gap rather than restoring the accident — `Self` is now substituted
at capture-emit time in `languages/rust/captures.ts`, where the impl node is
reachable, reusing the `findEnclosingImpl` + `syntheticCapture` idiom already
in that file.

CORRECTION to this PR's central claim. "709 removed / 0 added / 0 true edges
lost" was measured on a 762-file TYPESCRIPT corpus and stated without that
qualifier. Rust lost one true edge. The measurement stands for TypeScript; it
did not generalise, and the PR body is being updated to say so.

Scope of the breakage, measured rather than assumed: 1 failure in 2927 tests
across all 51 resolver files. Every other language — Go, Java, C#, Kotlin,
Swift, Python, PHP, Ruby, Dart, C++ — passes, which is why this is a targeted
fix and not a revert of the skip.

Re-baselined `bench/scope-capture` for RUST ONLY (655aed01 -> 7f1240b3); the
other 14 language fingerprints are byte-identical. The drift is the intended
output change and the reason is recorded in the baseline entry, per that
file's own "explain, never re-baseline to make CI green" rule.

Verified: rust resolvers 192/192; all 51 resolver files 2926 passed / 1
skipped / 0 failed; the 8 targeted suites 96/96; all 8 CI bench gates PASS;
`tsc --noEmit` clean; `detect_changes` reports one touched symbol
(`emitRustScopeCaptures`) and no affected flows.

* test(golden): refresh the Rust capture golden and the C# PDG snapshot (#2699)

The two committed artifacts CI flagged after 5f55fe46. They drifted for
OPPOSITE reasons, so each was inspected before regenerating rather than
refreshed on sight.

RUST GOLDEN — drifted because 5f55fe46 CORRECTS the output. A `Self` type
binding now records the enclosing impl's type instead of the literal `Self`,
in both the `let x = Self { .. }` and `fn new() -> Self` forms. Blast radius
verified exact: 5 fixtures drifted, all 5 contain `Self`, and every
`Self`-bearing rust fixture is among them (rust-self-struct-literal,
rust-constructor-type-inference, rust-default-constructor,
rust-method-enrichment, rust-scoped-multi-file).

C# PDG SNAPSHOT — drifted because the named-receiver Step-1 skip (59b892ca)
REMOVED A FALSE EDGE. CALLS 7 -> 6, and the edge that went is:

    Demo.Resolve.Parse@142:12#1 -> Demo.Resolve.Parse@142:12#1

a self-call, from `int Parse(string v) => int.Parse(v);`. `int.Parse(v)` is
System.Int32.Parse; the lexical chain was binding it to the enclosing local
function that happens to also be called `Parse`. Same defect class as
`writer.close()` -> GraphEmitSink.close. The snapshot's own comment says it
exists so "a future refactor that silently rewires the C-family graph trips
this gate" — it tripped correctly, and the rewiring is an improvement.

Both failures were PRE-EXISTING on this PR from 59b892ca, not from the three
commits above it — verified by reverting those and reproducing unchanged. They
went unseen because this PR's CI was never watched after its first push.

Verified after regeneration, WITHOUT update flags so they must genuinely pass:
rust-captures-golden 9/9; pipeline-pdg 31/31. The snapshot diff is 3 lines,
all inside the C# entry — no other language's snapshot moved. `detect_changes`
reports 0 changed symbols (test artifacts only).

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

* 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.

* 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
processes, all in EmitReceiverBoundCalls / EmitRubyMixinEdges. Verified: 85 test files /
1364 tests green, including every scope-resolution unit.

* 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.

Refs #2701

* 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.

fix(scope-resolution): stop platform builtins resolving to unrelated same-file symbols (#2549)
* fix(scope-resolution): stop platform builtins resolving to unrelated same-file symbols (#2545)

An unqualified call to a platform/language builtin (e.g. TypeScript's
global fetch()) could resolve to an unrelated same-file declaration
sharing that name, most visibly a Cloudflare Worker's
`export default { async fetch(req) {...} }` handler. Two contributing
gaps, both fixed:

- Object literals had no scope boundary in the TS/JS grammar queries,
  so a method's/property-arrow's name auto-hoisted past the literal
  into whatever lexically enclosed it (scope-extractor.ts's auto-hoist
  logic had nowhere to stop). Give object literals a Block scope, like
  6 other languages already do for lexical blocks.

- Independently, finalize's per-file bindings bucket
  (materializeBindings in gitnexus-shared) flattens every local
  declaration in a file onto its module scope for cross-file import
  resolution, regardless of true nesting -- so free-call-fallback's
  scope-chain walk could still hit the leaked binding at module scope.
  Guard free-call resolution: when a match for a known builtin name
  (LanguageProvider.isBuiltInName, already populated for TS/JS but
  never consulted by this pass) has no binding reachable via the true
  lexical scope chain, leave the call unresolved instead of emitting a
  false CALLS edge.

Verified against the full TS/JS resolver suites plus every other
language populating builtInNames (Python, Go, C/C++, C#, Dart, Kotlin,
PHP, Ruby, Rust, Swift, Vue) -- 2333 tests, no regressions.

* fix(scope-resolution): extend the #2545 scope-leak fix to Kotlin and Java

Anonymous object-expressions (Kotlin `object { ... }`) and anonymous
class bodies (Java `new Runnable() { ... }`) have the same missing
scope-boundary gap that caused #2545 in TypeScript/JavaScript: a method
declared inside has no scope of its own to stop the auto-hoist at, so
its name leaks past the container into the enclosing scope.

- Kotlin: `(object_literal) @scope.class` (distinct from the already-
  scoped named `object_declaration`/`companion_object`). Kotlin already
  populates `builtInNames`, so free-call-fallback's isBuiltInName guard
  (added for #2545) fully closes the equivalent leak here too --
  verified with a `println`-shadowing regression test.

- Java: `(object_creation_expression (class_body) @scope.class)`,
  matching PHP's existing `anonymous_class` handling. Java has no
  `builtInNames` list, so the isBuiltInName guard doesn't engage --
  the scope-tree fix is still correct and necessary (the anonymous
  class's own methods are now owned by the right scope), but an
  unqualified call to an unrelated same-file method sharing the
  anonymous class's method name can still resolve via finalize's
  per-file module-scope bucket (materializeBindings, shared/
  language-agnostic, intentionally not touched by this PR). Documented
  in the test as a known residual gap, same as TS/JS/Kotlin's own
  non-builtin-name collisions.

Audited every other language for the same shape (a value/container
node with no @scope.* capture hosting a would-be-auto-hoisted named
declaration): PHP and Vue already handle it correctly (PHP scopes
anonymous_class; Vue's <script> delegates to the now-fixed TS/JS
query). Ruby, Python, Dart, C#, Swift, Go, Rust, and C/C++ have no
query pattern that treats a literal/container value position as a
named declaration in the first place, so the bug shape can't occur
there.

Verified: full Kotlin + Java resolver suites, 468 tests, no
regressions.

* fix(scope-resolution): dedicated Object scope kind for object literals (#2545, #2551)

Review of the #2545 fix surfaced two defects, both fixed here:

1. The isBuiltInName guard suppressed genuine cross-file imports whose
   name matches a builtin (`import { fetch } from './fetch-polyfill'`
   silently stopped resolving -- verified regression vs. main). The
   leak the guard targets is inherently same-file (finalize's flat
   bucket is per-file), so the guard now also requires
   `fnDef.filePath === parsed.filePath`. New regression test covers
   the polyfill-import shape.

2. The sibling-property case of the reported bug was still broken and
   masked by a tautological assertion (`c.reason` -- a property that
   doesn't exist; the real path is `c.rel.reason` -- so the test
   passed regardless of behavior). In
   `export default { fetch() {...}, handler: () => fetch(...) }`,
   `handler`'s bare `fetch()` still resolved to its sibling. Reusing
   the `Block` scope kind was the root cause: correct for a real
   lexical block (a nested closure legitimately sees a sibling
   `let`/`const` from an enclosing `if`/`for`), wrong for object
   literals, whose members are reachable only via property access --
   never as bare identifiers, not even by sibling property bodies.

   Fix: a dedicated `Object` ScopeKind (gitnexus-shared) -- a hoist
   boundary whose own bindings scope-chain walkers never consult while
   still traversing past it to the parent. TS/JS object literals now
   emit `@scope.object`; the four chain walkers in
   scope-resolution/scope/walkers.ts (walkScopeChain,
   findAllCallableBindingsInScope, findCallableBindingsAndAdlBlocker,
   findExportedDefByName) and free-call-fallback's
   hasGenuineLexicalBinding skip Object scopes' bindings. Kotlin's
   anonymous `object {}` keeps `@scope.class` -- unlike JS object
   literals it has real implicit-this sibling dispatch.

Verified with the full resolver matrix run sequentially (TS 254, JS/
Kotlin/Java/Python/Go + TS variants 960, C/C++/C#/Dart/PHP/Ruby 1049,
Rust/Swift/Vue/Cobol + route/flow/unit suites 828, scope-extractor/
scope-tree units 51). Worker-pool crashes under parallel suite load
reproduced on unrelated files and pass in isolation (known flake, not
caused by this change).

* chore(autofix): apply prettier + eslint fixes via /autofix command

* feat(java): model anonymous class bodies as first-class Class nodes (#2550, step 1)

`new Runnable() { public void run() {} }` now emits a synthesized
javac-style `Class` node (`Worker$1`, `$N` = source order within the
top-level class) and owns its methods: the enclosing-owner walk
attributes `run` to `Worker$1` (re-keyed `Method:...:Worker$1.run#0`,
HAS_METHOD from the anonymous class) instead of the lexically enclosing
named class.

- `synthesizeJavaAnonymousClassName` (ast-helpers): single naming
  authority for every layer that keys the anonymous class; returns
  undefined for `object_creation_expression` without a `class_body`
  child, which also keeps it a no-op for C#'s same-named node type.
- `findEnclosingClassInfo`: anonymous-body branch before the generic
  container walk.
- JAVA_QUERIES: `(object_creation_expression (class_body))
  @definition.class` (no @name); `getLabelFromCaptures` now lets a
  nameless `definition.class` through — the parse-worker's existing
  `!nameNode && !extractedClassSymbol` gate still drops any nameless
  class the extractor cannot name, so other languages are unaffected.
- `javaClassConfig.extractName` synthesizes the name on the extractor
  path (worker node emission).
- Node identities move on unchanged files: INCREMENTAL_SCHEMA_VERSION
  7→8 and parse-cache SCHEMA_BUMP 17→18 (the v5 Route-identity
  precedent) force full re-analyze / cache invalidation.

Verified: new #2550 identity tests + resolve-enclosing-owner and
has-method suites (53 tests) green.

Prep for step 2/3 (scope-side ownership + receiver typeBinding) and the
free-call instance-ownership gate per
docs/plans/2026-07-18-gitnexus-plan-java-instance-scoped-freecalls.md

* feat(java): instance-scoped free-call resolution for anonymous-class methods (#2550, steps 2-4)

Completes the #2550 instance model on top of the Worker$N identity
commit:

- Scope-side ownership (java/captures.ts): synthesize
  `@declaration.class` + `@declaration.name` (`Worker$N`) anchored on
  the anonymous `class_body` — same range as its `@scope.class`, so the
  def lands in that Class scope's ownedDefs, `populateClassOwnedMembers`
  stamps `ownerId` on the anonymous class's methods, and the name
  auto-hoists exactly like a named class declaration.

- Receiver typeBinding (java/captures.ts + type-extractors/jvm.ts):
  `Runnable handler = new Runnable() { ... }` binds `handler` to the
  ANONYMOUS class (`Worker$1`), not the declared JDK interface — in both
  the scope-side TypeRef channel (receiver-bound Case 4) and the worker
  typeEnv. `handler.run()` now resolves through the receiver path
  (reason 'global', target `Worker$1.run#0`) instead of depending on
  the free-call finalize-bucket leak — which is why the prior gate
  attempt broke it (the #2550 landmine, now explained and structurally
  removed).

- Instance-ownership gate (free-call-fallback.ts + contract + run.ts +
  java opt-in): with `ScopeResolver.freeCallsRequireInstanceOwnership`,
  a free call may resolve to a `Method` only when the caller's
  enclosing class chain (self + MRO via `scopes.methodDispatch.mroFor`)
  contains the method's owner. Same-file matches only — the
  `materializeBindings` leak is per-file; cross-file Method matches come
  through genuine import channels (suppressing them broke the
  arity-narrowing parity suite, verified). Suppressions recorded as
  `'free-call-instance-ownership'` outcomes. Java opts in; every other
  language is byte-identical (flag off).

Result on the #2545 fixture: `process()`'s bare `run()` emits NO edge
to the unrelated anonymous method (the #2550 bug, closed), while
`handler.run()`, same-class implicit-this dispatch, and bare inherited
calls (MRO arm) all keep resolving.

Verified: full java.test.ts 223/223 twice sequentially (landmine gate);
cross-language matrix (TS/JS/Kotlin/Python/Go/C/C++/C#/Dart/PHP/Ruby/
Rust/Swift/Vue/Cobol + callable-value-flow + java-class-impact + core
units) — zero assertion failures; worker-crash flakes re-verified green
in single-file isolation.

Known deferral (documented): EXTENDS/IMPLEMENTS edges from the
anonymous class to its constructed type are not yet emitted, so a
same-file inherited-but-not-overridden member called ON the anonymous
instance does not resolve through the anon MRO; tracked as the
follow-up in #2550.

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix(java): anonymous-class inheritance, host coverage, and phantom-node guard (#2550 review)

Self-review of the instance model (gitnexus-review with empirical lens
probes) surfaced three defects, all fixed:

1. HIGH — the ownership gate suppressed TRUE bare calls to inherited
   methods inside an anonymous body extending a same-file class
   (`new Base() { void extra() { work(); } }` lost `extra -> work`):
   the anon class had no inheritance edge, so `mroFor(Worker$N)` was
   empty and the MRO arm could never pass. The synthesis now emits an
   `@reference.inherits` for the constructed type, anchored on the
   `class_body` so the reference's enclosing class resolves to the
   SYNTHESIZED def (anchoring on the type node would sit outside the
   anonymous scope and attribute the edge to the wrong class). Anon
   classes now get real EXTENDS/IMPLEMENTS edges and inherited bare
   calls pass the gate.

2. MEDIUM — hostless anonymous bodies materialized a phantom Class
   node named after the CONSTRUCTED type (`Class:...:Runnable`) via
   extract()'s extractTypeNameFromNode fallback. New
   `shouldSkipClassCapture` in javaClassConfig drops the capture when
   no name can be synthesized.

3. MEDIUM — enum/interface/record-hosted anonymous bodies silently
   fell back to the pre-#2550 model (mis-attribution + open leak).
   The topmost-host walk now accepts all four host type declarations
   (JAVA_ANON_HOST_TYPES), so `EnumHost$1` etc. are modeled; the
   phantom-node shape disappears for those hosts as a side effect.

Also: per-parse-tree WeakMap memo for the `$N` numbering — the helper
is called from four independent layers per anonymous body and each call
re-scanned the host subtree (`descendantsOfType`), quadratic on
anon-heavy files (old-style listener-per-widget Java); and the
scope-capture bench fingerprints rebaselined for java/typescript/
javascript/kotlin (`measure.mjs --check` now passes all 14 languages —
it failed for every scope query this PR touched; drift notes added per
the file's convention).

Verified: full java.test.ts 225/225; all 11 #2550 tests including the
new anon-extends-base and enum-host scenarios; bench --check PASS.

Known remaining (documented, unchanged-old behavior): enum CONSTANT
bodies (`A { ... }`) stay unmodeled; nested-host naming is top-level-
anchored (`EnumWrap$1`, not javac's `EnumWrap$Mode$1`).

* chore(autofix): apply prettier + eslint fixes via /autofix command

* test(storage): update the INCREMENTAL_SCHEMA_VERSION pin to v8 (#2550)

The U-C5 reuse-gate test deliberately pins the exact schema version so
a bump cannot land without consciously extending the gate expectations.
Extend for v8 (Java anonymous-class node identities, #2550): a v7 stamp
now fails the strict-equality reuse gate — a pre-v8 index would strand
old `Worker.run`-keyed Method nodes alongside the re-keyed
`Worker$N.run` ones on unchanged files — and v8 passes.

Caught by CI (tests/ubuntu coverage shard 2/3 on PR #2549); the local
matrix had not included this unit file. All 7 schema-referencing unit
suites verified green (109 tests).

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.

* test(scope-resolution): cover value-ref registration and property dispatch (#2437)

Integration: same-file/cross-file/aliased/shorthand registrations emit USES;
non-callable and destructuring values emit nothing; dispatch sites gain
property-dispatch CALLS (incl. JS twins and per-language partitioning);
fan-out-capped keys are dropped entirely; factory-call values unchanged.
Unit: capture-shape pins for @reference.value-ref + @reference.property-key.

* fix(scope-resolution): surface dropped property-dispatch keys in stats (#2437)

Review finding: skippedKeys was returned but discarded — a hook table
larger than the fan-out cap silently reopened the #2437 gap for those
keys. Log dropped keys and fold value-ref USES + dispatch CALLS into
referenceEdgesEmitted.

* 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
discarded and RunScopeResolutionStats had no field, so the PR-body claim
'includes them in resolver statistics' was unimplemented (review finding,
#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
was typed, parsed, validated, and unit-tested with hand-built input (review
finding 16, #2522; YAGNI). Re-add with a real producer if C++ qualified
member declarators ever need it.

* refactor(scope-resolution): drop dead callable-flow knobs

CallableFlowPassingMode 'callable-object' had no producer and no consumer
distinguishing it, and CallableFlowCaptureOptions.extractCallArguments had
no language providing it (unlike its live sibling extractCallCallee) —
review finding 17, #2522 (YAGNI). The invocation-kind 'callable-object'
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.

* fix(php): remove nonexistent optional_parameter node type

tree-sitter-php has no 'optional_parameter' — defaults ride on
simple_parameter — so the entry was dead weight the #1920 literal gate
does not cover for capture-option Sets (review finding 19, #2522).

* 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
case unchanged.

* 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

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).

The 1,100-line shared synthesizer had no test naming it — only downstream

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.

* 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.

* feat: add Spring DI resolver for @Autowired List<T> injection

Addresses all P0/P1 findings from tri-review (#2200):
- P0: Register INJECTS in RelationshipType union (compiles)
- P0: Rewrite execute() to emit consumer→implementation edges from graph data only
- P1: Register in VALID_RELATION_TYPES, single-pass O(N) indexes
- P1: Java-only gate with early exit on non-Java repos
- P1: Update FULL_ORDER golden test
- 8 unit tests covering all edge cases

* test: make VALID_RELATION_TYPES size assertion array-driven (no hardcoded count)

The security test hardcoded toBe(16) for the relation type count, but PR #2200
added INJECTS, bumping it to 17. Replace the magic number with an
EXPECTED_RELATION_TYPES array whose .length drives the size assertion,
so future additions only need to append to the list.

Fixes CI failure on PR #2200.

* fix(ingestion): thread raw generic field types onto Property nodes so Spring DI matching works (review 4616076037 P0)

Production declaredType is generics-stripped by design (extractSimpleTypeName:
List<Shape> -> "List"), so the spring-di phase's anchored regexes could never
match real extraction output — the phase was a silent no-op on every real Java
repository, while its unit tests passed against hand-built node shapes.

Add FieldInfo.rawDeclaredType captured verbatim from the field's type node
(.text, generics and qualifiers preserved — same precedent as the JVM method
extractor), thread it through both parse-worker Property sites, add it to the
shared NodeProperties contract, and match on rawDeclaredType ONLY (no
declaredType fallback: it can never match real data and would mask future
plumbing regressions as quiet no-ops).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(ingestion): gate Spring DI on real injection annotations, honest edge reason (review 4616076037 P1)

Extract Java field annotations (shared extractAnnotations helper, moved
verbatim from the method extractor) onto Property nodes and require
@Autowired or @Inject before a collection field becomes an INJECTS
candidate. Previously every edge's reason string fabricated "@Autowired"
without any annotation ever being checked, and any plain collection field
would have fanned out false edges once matching worked.

@Resource is deliberately excluded: JSR-250 resolves by bean name first
(defaulting to the field name), injecting a single named collection bean —
the opposite of the collect-all-implementers fan-out INJECTS models. Pinned
by a test.

An annotated candidate missing rawDeclaredType now logs an isDev warning
(plumbing-contract breach signal) instead of vanishing silently.

SCHEMA_BUMP 9 -> 10: Property nodes gained rawDeclaredType + annotations;
warm parse caches must invalidate or the DI phase silently no-ops on
replayed pre-upgrade nodes (the #2038 trap).

* refactor(ingestion): framework-neutral di phase + language-scoped Spring matcher registry (review 4616076037 P1)

spring-di was the only pipeline phase naming a language in shared
core/ingestion code (DoD.md language rule; the maintainer's direction is a
generic DI solution). Split it:

- di-extractors/spring.ts: the Spring matcher (annotation gate, collection
  type parse, @Resource exclusion rationale, framework-specific reason
  payload) — language-scoped home, mirroring route-extractors/.
- di-extractors/index.ts: DI_MATCHERS, a single-valued
  ReadonlyMap<SupportedLanguages, DiFieldMatcher> mirroring the
  SCOPE_RESOLVERS registry shape sanctioned by AGENTS.md. Constructor
  injection deliberately out of scope; widen to arrays only when a second
  same-language framework lands.
- pipeline-phases/di.ts (renamed from spring-di.ts): framework-neutral —
  routes Property nodes to registered matchers by node language via a typed
  guard, then runs the unchanged reverse-index fan-out. Zero language or
  framework names remain (grep-verified).

* fix(ingestion): language- and qualified-name-scoped interface resolution for DI fan-out (review 4616076037 P2)

The interface index was built from ALL Interface nodes regardless of
language, keyed by bare simple name with last-writer-wins overwrite —
a polyglot repo with a TS and a Java 'Shape' could fan Java INJECTS edges
into TypeScript classes, and two same-named Java interfaces in different
packages silently collapsed to whichever parsed last (documented GitNexus
bug class: #2054, PR #1956).

Resolution is now per-language with qualifiedName as the primary key
(Interface nodes already carry package-qualified qualifiedName); dotted
element types resolve via qualifiedName, bare names via a per-language
simple-name index that records ambiguity and fails CLOSED. Ambiguity skips
are observable: DIOutput.ambiguousSkipped + an aggregated isDev debug log,
so 'no DI fields' is distinguishable from 'all candidates ambiguous'.
Same-package tiebreaking is a pinned, documented follow-up.

Order-independence pinned by running collision tests in both insertion
orders.

* fix(ingestion): depth-aware Spring collection-type parser for idiomatic generics (review 4616076037 P3)

The two anchored regexes silently skipped idiomatic Spring shapes:
Map<Pair<A,B>, IFoo> (nested-generic key broke the [^,]+ split),
List<? extends IFoo> / List<? super IFoo> (bounded wildcards),
java.util.List<IFoo> (qualified wrapper), and whitespace/multi-line
declarations.

Replace them with a small scanner: whitespace normalization, wrapper
matched by last dotted segment, depth-aware top-level-comma split, wildcard
bound stripping, and a final plain-dotted-type-name gate so anything else
(nested-generic elements, arrays, unbounded wildcards, embedded comments,
unbalanced brackets) fails closed. Every accept and reject is documented in
the module docstring and pinned by 27 table-driven cases.

* test(integration): prove Spring DI end-to-end through the real pipeline (review 4616076037 P1)

Both no-op incarnations of this feature shipped with a green unit suite
because every test hand-built the exact graph shape the phase expected —
no test ever ran real Java source through the actual extraction pipeline.

Add test/integration/spring-di-pipeline.test.ts: real .java fixtures via
runPipelineFromRepo, pinning (a) the extraction contract on the annotated
field's Property node (declaredType 'List', rawDeclaredType 'List<IFoo>',
annotations ['@Autowired']), (b) set-equality on ALL INJECTS edges
(exactly Consumer->FooA and Consumer->FooB; the non-annotated 'plain'
field of the same type contributes nothing; no self-edges), and (c) a
negative-control fixture with no injection annotations producing zero
INJECTS edges. Either historical regression fails at least one of these.

* fix(incremental): register INJECTS across product surfaces + delete-before-writeback (review 4616076037 P2)

INJECTS was allowlisted in VALID_RELATION_TYPES but invisible or unhandled
everywhere else. Register it deliberately:

- REL_TYPES (gitnexus-shared schema-constants): web-side validRelType()
  otherwise silently rejects INJECTS filters (CLI/web single source of truth).
- mcp/tools.ts cypher edge list (agent-facing schema discovery).
- isGraphWideRelType: INJECTS validity is a whole-program property — a
  change to a THIRD file (the interface, or a new/removed implementer)
  creates/invalidates edges between two untouched files (the TAINT_PATH /
  #2084 M4 U6 class), so incremental extraction must always re-include the
  full fresh set.
- deleteAllInjects (lbug-adapter): mirrors deleteAllInterprocTaintPaths —
  COUNT-then-DELETE under withConnLock, benign missing-table carve-out,
  re-throw otherwise (CodeRelation has no PK and there is no read-side
  dedup; a fail-soft delete + re-add would silently duplicate rows).
- run-analyze.ts: the delete is UNCONDITIONAL, next to the Communities
  delete — deliberately NOT inside the options.pdg block: the di phase runs
  on every persisting analyze while the graph-wide re-include is
  unconditional, so a pdg-gated delete would append without deleting on
  every non-pdg incremental run (N runs = N copies).
- local-backend.ts comment: opt-in traversal by design (not in default
  impact()/context() lists; no IMPACT_RELATION_CONFIDENCE entry per the
  WRAPS/FETCHES precedent — edges carry their own 0.8).
- ARCHITECTURE.md: 14 -> 15 phases, DAG diagram, phase table, skip-list.

Note: the tools.ts edge list also predates WRAPS/QUERIES/USES — that drift
is pre-existing and left for a follow-up.

Idempotency pinned end-to-end: two successive incremental runs (real
runFullAnalysis + real LadybugDB, unrelated-file touches) leave the INJECTS
row count stable.

* docs: describe INJECTS' actual precondition; drop stale fixed-at-16 comments (review 4616076037 P3)

The shared-schema doc for INJECTS claimed an @Autowired precondition the
code (pre-fix) never checked, and hardwired Spring semantics into what is
now a framework-neutral edge type. Reword: precondition is an injection
annotation recognized by a per-language matcher in di-extractors/;
framework specifics live in the reason payload, not the type contract.

security.test.ts comments still said the allow-list size 'stays fixed at
16' (it is 17 and the assertion derives from EXPECTED_RELATION_TYPES).

* refactor: simplify DI surfaces — narrow matcher contract, dedup delete-alls, derive tools edge list

Post-implementation simplification pass (4 review angles):

- DiFieldMatch/CandidateField carried collectionType + matchedAnnotation
  that no consumer read (the matcher bakes both into reason) — narrowed to
  {elementTypeName, reason}.
- parseElementTypeName had two guard branches fully subsumed by the final
  plain-dotted-type-name gate — deleted, rationale folded into the regex
  comment.
- The three byte-identical delete-all-by-rel-type functions in lbug-adapter
  (TAINT_PATH / CALL_SUMMARY / INJECTS) are now one parameterized helper +
  thin wrappers with identical names, signatures, and message text
  (character-diff verified) — the missing-table regex and abort policy now
  live in exactly one place.
- The cypher tool's hand-maintained edge-type list (already missing
  WRAPS/QUERIES/USES) is now derived from the canonical REL_TYPES — the
  drift class is gone rather than patched.
- di phase: interface indexes are built only for languages that actually
  have candidates; test builder gained a rawDeclaredType opt-out replacing
  a hand-rolled node.

* fix: apply Tier-2 review findings — qualified-name fail-closed, honest cypher docs, pinned delete contract, hook isolation

- byQualifiedName was last-writer-wins on duplicate qualified names
  (reproduced: order-dependent INJECTS edges with ambiguousSkipped 0 —
  same package+interface duplicated across monorepo modules/source roots;
  Java qualifiedName has no file-path component). Both indexes now share
  the AMBIGUOUS fail-closed sentinel; order-flip test added.
- The REL_TYPES-derived cypher edge list advertised pdg-gated types with
  no caveat (LLM queries on them silently return zero rows on default
  indexes) — caveat appended, INJECTS example added, impact relationTypes
  description now names the DI fan-out opt-in.
- The delete-all re-throw contract (only defense against duplicate
  CodeRelation rows) was untested — error classification extracted to a
  pure classifyDeleteAllError and pinned exhaustively.
- extractRawType/extractAnnotations hooks lacked the per-hook try/catch
  the pipeline applies elsewhere (#2286 pattern): a throwing hook would
  silently drop every remaining file in the language group. Hardened,
  degradation tested.

feat(pdg): control dependence — post-dominators + CDG (Ferrante) [M5 #2085] (#2188)
* feat(pdg): add CDG + POST_DOMINATE edge types (M5 #2085)

* feat(pdg): post-dominator tree on reverse CFG (M5 #2085)

* feat(pdg): Ferrante control-dependence over the post-dom tree (M5 #2085)

* feat(pdg): emitFileCdg + optional POST_DOMINATE debug edges (M5 #2085)

* feat(pdg): wire CDG emission in-phase + pdgModeMismatch CDG-cap stamp (M5 #2085)

* test(pdg): CDG snapshot + end-to-end pipeline answerability (M5 #2085)

* fix(review): apply autofix feedback (M5 #2085)

* fix(pdg): label CDG edges by controller arm sense, not edge kind (#2188 F1/F2/F4)

Tri-review (with Codex as the independent engine) found the CDG 'T'/'F' label
was wrong for the commonest control flow: the M1 TS visitor wires a condition's
fall-through FALSE arm as `seq`/`loop-back`, but `branchSense` mapped both to
'T', so guard clauses, if-no-else, and loop `break` got 'T' instead of 'F' (F1,
P1). The structural CDG edges were correct; only the label — the AC3 "under what
condition does X run?" answer — was wrong.

- F1: replace edge-kind `branchSense` with controller-arm-sense `labelFor`. An
  ambiguous fall-through edge (seq/loop-back) takes the COMPLEMENT of its source
  block's explicit cond-true/cond-false sibling arm. This correctly handles
  do/while (loop-back = TRUE arm) and inner-if-in-loop (loop-back = FALSE arm) —
  the ambiguity a kind→label table cannot resolve. Adds real-parser regression
  tests (the hand-built tests used a fictional cond-false edge and missed it).
- F2: correct the false "sound over-approximation that never drops a real
  dependence" claim in post-dominators.ts — exit-unreachable regions both drop
  and invent control dependences (latent for the current TS visitor, which keeps
  EXIT reverse-reachable). Reframe the exit-less-loop test to characterize, not
  bless, the degenerate behavior.
- F4: make the AC2 property-test reference compute post-dominance INDEPENDENTLY
  (node-removal reachability, no shared code with post-dominators.ts), so a
  post-dom direction bug can no longer pass both the impl and the reference.

* fix(ci): root-prettier format + run-analyze pdg stamp gains maxCdgEdgesPerFunction (#2085)

Two deterministic CI failures from the M5 CDG work:
- quality/format: basicblock-roundtrip.test.ts failed CI's root `prettier --check .`
  (the pre-commit hook uses the gitnexus-local prettier config, which differs);
  reformatted with the root config.
- tests/ubuntu/coverage: run-analyze.test.ts pinned the resolved RepoMeta.pdg
  shape (DEFAULTS) and the all-zero cap override without the new
  maxCdgEdgesPerFunction key (default 5000); added it so resolvePdgConfig
  toEqual and pdgModeMismatch(DEFAULTS) pass. (The stale-test sweep missed this
  file in PR #2188 — same trap M2 hit.)

* feat(mcp): add pdg_query tool definition (controls/flows modes) [M6 #2086]

* feat(mcp): pdg_query backend — controls (CDG) + flows (REACHING_DEF) + e2e test [M6 #2086]

* feat(mcp): document PDG edges + pdg_query (schema, cypher, skill, --pdg-gated ai-context) [M6 #2086]

* fix(mcp): correct pdg_query symbol-anchor lower bound + harden inputs [PR #2188 review]

Tri-review (Codex + adversarial + correctness lanes) of the M6 pdg_query
surface found the symbol-anchor window over-includes a neighbor function's
block. The upper bound was widened to the 1-based BasicBlock basis (symEnd+1)
but the lower bound was left 0-based, so a block on the line directly above the
target function leaked into the result. Shift both bounds +1 ([symStart+1,
symEnd+1]) so the window is the function's true block span.

Also from the same review:
- pdg_query no longer throws on a no-arguments MCP call: the dispatch passes
  raw `params`, so default it to {} → a clean mode-validation error instead of
  a TypeError. (`explain` shares this latent pattern — pre-existing follow-up.)
- tools.ts: the controls-mode description no longer hard-codes the 'F' branch
  sense for guards — `if (!ok) return;` rides the predicate's 'T' arm; the
  guard:true flag is label-agnostic (regex on the dependent block text).

Tests: a hand-seeded adjacency regression (verified failing without the
lower-bound +1) + a no-arguments validation test. Skill doc updated to document
the two-sided [symStart+1, symEnd+1] window.

* fix(mcp): drop always-true anchor conditional in pdg_query [CodeQL #2188]

CodeQL alert 756 flagged `...(anchor ? { anchor } : {})` in _pdgQueryImpl as a
useless conditional: `anchor` is unconditionally assigned in both the file-path
and symbol branches before the return (the not-found/ambiguous/no-layer paths
return earlier), so it is always truthy. Drop `| undefined` from the declaration
(TypeScript definite-assignment holds across both branches) and emit `anchor`
directly.

No runtime change — the `anchor` field was already present on every result.

* test(cli): add hasPdg to the noStats bridge expectation [#2188]

The M6 work threaded `hasPdg: options.pdg === true` into the AIContextOptions
passed to generateAIContextFiles on the --skills regeneration path, but this
test's strict .toEqual expectation predated it (4 keys vs 3 → CI failure). Add
`hasPdg: false` (the value on this non---pdg path). The assertion stays strict;
the #1477 noStats bridging it guards is unchanged.

* refactor(cli): collapse generateGitNexusContent params to an options bag [#2188]

The function had grown to 9 positional params; reaching `hasPdg` meant passing
six `undefined`s (the M6 review's maintainability flag). Collapse params 3-9
(generatedSkills, groupNames, noStats, skipSkills, runnerPath, defaultBranch,
hasPdg) into a `GitNexusContentOptions` object with the defaults moved to
destructuring. The body is unchanged (same local names); the single production
caller and the test calls become self-documenting named fields.

Pure refactor — generated AGENTS.md/CLAUDE.md content is byte-identical.

* fix(cfg): skip CDG for exit-unreachable CFGs (unsound post-dominance) [#2188]

M5 review P2: computePostDominators roots only at cfg.exitIndex and nothing
enforced that EXIT is reachable from every block. For an entry-reachable region
that cannot reach EXIT (a non-terminating loop, or a multi-terminal CFG a future
visitor might emit) the EXIT-rooted reverse walk degenerates — it both drops
real control dependences and invents spurious ones.

Add a pure precondition predicate `isExitReachableFromAllBlocks` (co-located with
the algorithm it guards) and gate it in emitFileCdg: a CFG that violates it is
skipped for CDG (counted as skippedUnsoundFunctions + one onWarn), while its CFG
and REACHING_DEF projections — which do not depend on post-dominance — are kept.
A CDG-specific gate, not a widening of isEmitSafeCfg, so the blast radius is
exactly the unsound CDG. The current TS visitor always satisfies the
precondition (every loop gets a structural header→loopExit edge), so CDG output
for real fixtures is unchanged.

* fix(cfg): bound computeControlDependence materialization (heap parity) [#2188]

M5 review P2: unlike computeReachingDefs (maxFacts) and the emit-side edge cap,
computeControlDependence materialized the full deduped seen/out before
emitFileCdg's per-function cap could trim it — O(edges × post-dom depth) heap
for a deeply nested function.

Add a `maxEdges` ceiling (default 0 = unbounded) returning {edges, truncated},
mirroring computeReachingDefs's {facts, truncated}. The ceiling is checked
before pushing a new unique edge, so `truncated` means a genuine overflow (not
merely "reached cap"). emitFileCdg passes a FIXED materialization ceiling (8× the
default edge cap) — deliberately NOT derived from the runtime edge cap, because
CDG's materialization IS the deduped-edge quantity the cap reports on (deriving
it would pre-truncate that set and lose the exact dropped count). A ceiling hit
is surfaced via onWarn + the truncated flag — never silent.

* refactor(mcp): share resolveBlockAnchor; fix explain's anchor off-by-one [#2188]

M6 review P2 (duplication) + the flagged pre-existing _explainImpl correctness
follow-up. _pdgQueryImpl and _explainImpl each carried a near-identical
symbol↔block anchor resolver that had DRIFTED: pdg_query used the corrected
[symStart+1, symEnd+1] window (BasicBlock startLine is 1-based, the symbol span
0-based) while _explainImpl still used [symStart, symEnd] — dropping a taint
source on the function's final line AND leaking a neighbor's block on the line
directly above.

Extract one `resolveBlockAnchor` helper, used by both, that applies the correct
window and a single (bare) clause convention (callers compose their own WHERE).
This removes ~50 duplicated lines and fixes explain's anchor in one place.

A hand-seeded characterization test (taint-explain Block 4) pins both bounds —
verified to FAIL on the pre-fix window (it returned the line-10 neighbor instead
of the line-15 final-line source). Existing taint-explain + pdg-query suites are
unchanged (their fixtures have interior sources/sinks).

* fix(mcp): pdg_query reports "status unknown" when the layer can't be confirmed [#2188]

M6 review P3 (Codex): when meta is UNREADABLE and the bounded global existence
probe returns zero rows of the edge type, _pdgQueryImpl asserted "no PDG layer"
— but a genuinely edge-free layer (all-linear functions) is indistinguishable
from a missing one via that probe. Soften only that fallback path to an
inconclusive "PDG layer status unknown — was this repo indexed with --pdg?"
note. The meta-stamped path (stamp present, cap absent ⇒ layer truly missing)
keeps the definitive "no PDG layer" wording.

M6 review test-gap follow-ups, all hand-seeded with controlled data:
- ambiguous symbol name → status:'ambiguous' + ranked candidates shape
  (uid/name/filePath/score), never a silent guess;
- total/truncated page boundary in both directions (limit below the match count
  sets truncated with the full total; limit above it omits truncated);
- a Windows-style filePath containing ':' resolves and fnLineOf decodes the
  function-line segment correctly (split-from-right past the drive letter).

* docs(skills): ship gitnexus-pdg-query skill mirrors + add pdg_query to the guide [#2086]

M6 bundled pdg_query into this PR, but the skill shipped only in the canonical
gitnexus/skills/ root. Mirror it (byte-identical) to the two hand-maintained
roots the sibling taint skill uses — .claude/skills/gitnexus/ and the plugin —
so Claude Code + plugin users get it too.

Also extend the gitnexus-guide tool reference (all 3 copies, now byte-identical):
add a `pdg_query` row + a "Control & data dependence" section mirroring the
taint/`explain` section, and reconcile the pre-existing drift where only the
.claude copy carried the `check` tool row (a real registered tool) — all three
now list it.

* docs(architecture): refresh CFG/PDG section for the full M1–M6 stack [#2086]

The PR body had deferred the "ARCHITECTURE docs refresh" to #2086; now that M6
ships here, do it:
- MCP tools table gains `explain` and `pdg_query` (were absent).
- "Optional CFG/PDG emission" was M1-only; rewrite to cover the whole opt-in
  stack — M1 CFG, M2 REACHING_DEF, M3/M4 taint, M5 CDG (Ferrante over CHK
  post-dominators, with the exit-unreachable skip), M6 read surface (pdg_query +
  explain, anchored + LIMIT-bounded, shared resolveBlockAnchor) — and note the
  no-Function→BasicBlock-edge join.
- LadybugDB schema notes the `--pdg` additions: the `BasicBlock` node table and
  the CFG/REACHING_DEF/CDG/TAINTED/SANITIZES/TAINT_PATH relation types, kept out
  of the default VALID_RELATION_TYPES / web schema.

feat(ingestion): add control-flow-graph layer for TS/JS (#2081) (#2099)
* feat(cfg): language-agnostic CFG construction core (#2081)

U1 of M1 (CFG layer). Plain JSON-serializable CFG data model (BasicBlockData/
CfgEdgeData/FunctionCfg — must survive the worker→main boundary + ParsedFile
store), a CfgBuilder accumulator (leaders→blocks→edges, synthetic ENTRY/EXIT,
idempotent edges), a ControlFlowContext (break/continue/switch + labeled-jump
target stacks), and a TraversalResult ({entry, dangling exits}). AST-agnostic
and unit-tested on the classic control-flow topologies (if/else, while back-edge,
mid-block return, labeled break/continue) the S2 spike validated; reachability
helper backs the R9 property test.

* feat(ingestion): U2 — TS/JS CFG visitor over tree-sitter AST (#2081)

Add the TS/JS CfgVisitor that walks a function's tree-sitter AST and drives
the U1 CfgBuilder to produce a serializable FunctionCfg. One visitor covers
both languages (shared grammar family).

Handles the classic CFG hazards explicitly (R2, R10):
- loops allocate a dedicated loop-exit block so `break` has a concrete target
  before the loop's successor is known; `continue`/back-edge close the loop
  (while, do-while, C-for with init-once + increment-as-continue-target,
  for-in, for-of)
- switch fallthrough falls out naturally: a non-breaking case yields exits we
  wire to the next case as `fallthrough`; a breaking case wires to the switch
  exit via ControlFlowContext
- try/catch/finally: normal completion AND exceptional flow both route through
  finally (post-domination); a conservative exceptional edge models that the
  protected region may raise to its handler (not just explicit `throw`)
- labeled break/continue resolve against the labeled loop's frame
- early return/throw wire to EXIT/handler and terminate their block

19 hazard tests (one per construct) + AC1 10-function fixture; all green.
No change to the committed U1 core or ControlFlowContext.

* feat(ingestion): U3 — worker CFG build + cfgSideChannel + cache coherence (#2081)

Run the CFG visitor in the parse worker (where the AST lives), serialize the
per-function CFG onto a new ParsedFile.cfgSideChannel, and keep it coherent
across the disk-backed store and the warm/durable parse cache (R3, R4).

- gitnexus-shared parsed-file.ts: add `cfgSideChannel?: unknown` as a DISTINCT
  field from captureSideChannel (different producer/consumer/lifecycle; plain
  JSON data — blocks/edges deliberately lack the `nodeId` the store's interning
  reviver keys on, so no mis-interning).
- cfg/types.ts + visitors/typescript.ts: add CfgVisitor.isFunction so the worker
  enumerates functions (and applies the line budget) by a cheap node-type test.
- cfg/collect.ts (new): collectFunctionCfgs walks the tree, builds one CFG per
  function (nested included), applies maxFunctionLines (over-cap = skipped).
- language-provider.ts: add `cfgVisitor?: CfgVisitor<SyntaxNode>` hook;
  typescript.ts attaches it to both the TS and JS providers (shared grammar).
- parse-worker.ts: read pdg + pdgMaxFunctionLines from workerData (read once at
  init — the worker never sees PipelineOptions), gate the build, attach
  cfgSideChannel alongside captureSideChannel.
- parse-cache.ts: bump SCHEMA_BUMP 4→5 (ParsedFile shape changed) and fold the
  pdg flag into computeChunkHash so a pdg-off cached chunk is NOT reused on a
  --pdg run (the #2038-class warm-cache trap). Default path keeps its keys.
- worker-pool.ts + parse-impl.ts + pipeline.ts: thread pdg/pdgMaxFunctionLines
  PipelineOptions → WorkerPoolOptions → workerData, and into the chunk-hash key.

9 boundary tests: collect contract, JSON round-trip identity (no AST leakage),
the pdg cache-key guard, the line-cap skip, and the no-visitor gate. Full CFG
suite (U1+U2+U3) green; build clean.

* feat(ingestion): U4 — emit BasicBlock + CFG within scope-resolution (#2081)

Emit persisted BasicBlock nodes + CFG edges from each ParsedFile's worker-built
cfgSideChannel, INSIDE scope-resolution's Phase-4 graph emission — the last
point where the worker-built CFGs are loaded (emitParsedFiles carries the
channel; the disk store is cleared right after the orchestrator returns). This
is the architecture the doc-review corrected to: a standalone post-`mro` phase
(the issue's literal subtask) provably reads empty data (KTD1).

- cfg/emit.ts (new): pure emitFileCfgs(graph, cfgs, maxEdgesPerFunction, onWarn).
  BasicBlock id = `BasicBlock:<filePath>:<functionStartLine>:<blockIndex>`
  (KTD3 — funcStart disambiguates blocks across functions in one file; no
  `name` column). CFG edge = CodeRelation type 'CFG' with the edge KIND
  (seq/cond-true/…) in `reason` (kinds can't be their own edge type). Per-
  function edge cap stops at the cap and warns with the dropped count — no
  silent truncation (R6/KTD6).
- run.ts: pdg-gated emit pass over emitParsedFiles after emitPostResolutionEdges
  (store still live); RunScopeResolutionInput gains pdg + pdgMaxEdgesPerFunction.
- phase.ts: thread ctx.options.pdg / pdgMaxEdgesPerFunction into the call.
- pipeline.ts: PipelineOptions.pdgMaxEdgesPerFunction.

6 tests: node/edge shape (KTD3 id, no name, type='CFG', kind in reason),
cross-function id uniqueness, AC2 reachability-from-ENTRY property, the edge
cap's no-silent-truncation contract, and empty-input no-op. Flag-off
byte-identity + full runPipelineFromRepo round-trip land in U7. Build clean.

* feat(cli): U5 — `--pdg` opt-in plumbing (CLI + .gitnexusrc → both sinks) (#2081)

Expose the CFG/PDG substrate as an opt-in and thread it from CLI/.gitnexusrc to
the single source of truth (PipelineOptions.pdg), which fans out to BOTH sinks
already wired in U3/U4: the worker build gate (workerData.pdg) and the
scope-resolution emit gate. Off by default (R7).

- cli/index.ts: `--pdg` commander flag.
- cli/analyze.ts: AnalyzeOptions.pdg + pass `pdg` into runFullAnalysis options.
- cli/analyze-config.ts: KEY_SPECS `pdg` (boolean) so `.gitnexusrc { "pdg": true }`
  normalizes and a non-boolean value fails closed with GitNexusRcError.
- core/run-analyze.ts: AnalyzeOptions.pdg → runPipelineFromRepo({ pdg }).

(The internal PipelineOptions/WorkerPoolOptions/workerData fields + the
parse-cache key fold landed in U3/U4; this unit adds the user-facing surface.
The budget knobs stay at internal defaults for M1.)

Tests: analyze-config pdg normalization + non-boolean rejection; opt-in.test.ts
covers the CLI/file merge precedence and that pdg perturbs the chunk-dispatch
key. The full worker-build + main-emit round-trip is the U7 integration test.

* test(ingestion): U7 — CFG acceptance fixtures, parity, end-to-end + docs (#2081)

Acceptance criteria for the M1 CFG layer:
- AC1: a 10-function TS fixture's CFG node/edge set matches a committed snapshot
  (cfg-snapshot.test.ts).
- AC2: every BasicBlock is reachable from its function ENTRY (property test over

* test(ingestion): drop unused helper in cfg-snapshot test (#2081)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(review): apply ce-code-review autofix feedback (#2081)

Review (10 reviewers) confirmed OFF-path byte-identity (adversarial + golden)
and found defects all within the --pdg path. Fixes:

- P1 same-line BasicBlock id collision: add a start-column disambiguator to
  FunctionCfg + the id (`BasicBlock:<file>:<line>:<col>:<idx>`) so two functions
  sharing a start line no longer collide under first-writer-wins addNode.
- P1 worker crash-cascade: per-file try/catch around collectFunctionCfgs so a
  CFG-build throw cannot escape to the language-group catch and silently drop
  every remaining file in the group.
- P2 edge-cap drop now logs unconditionally (input.onWarn is validator-gated/
  silent in prod) — upholds the no-silent-truncation guarantee.
- P2 Array.isArray guard before the cfgSideChannel cast in run.ts.
- P2 maxFunctionLines default: worker applies DEFAULT_PDG_MAX_FUNCTION_LINES=2000
  when unset; caps forwarded through run-analyze AnalyzeOptions (closes the
  server-path drop).
- P3 README duplicate paragraph removed; `0`-vs-default docstrings corrected;
  CLI --pdg flag made language-neutral; reachableBlocks JSDoc corrected.
- Documented the break-through-finally + stacked-label CFG limitations.
- Tests: same-line id-collision regression, standalone throw→EXIT, dead-code-
  after-return, async/generator/method coverage, strengthened labeled-continue.

Refuted: the HTTP-500 getNodeQuery finding — M0 already shipped the BasicBlock
branch + name-floor (R12/web-safety handled).

CFG + analyze-config suites: 95 tests green; golden parity (AC4) byte-identical.

* perf(ingestion): benchmark CFG construction + O(n) block-text accumulation (#2081)

Closes the M1 review's requires_verification perf gap ("no benchmark for
collectFunctionCfgs; a wall-time + cfgSideChannel byte-size regression gate
would catch the extendBlock concatenation before kernel scale").

- bench/cfg/measure.mjs (new): build-free tsx harness timing collectFunctionCfgs
  (parse once, reuse the tree) across three scaling scenarios — straight-line
  (extendBlock path), many-functions (collect walk), branchy (block/edge growth)
  — at 500→2000. Reports a wall-time scaling ratio AND a cfgSideChannel
  byte-size ratio, plus an order-independent sha256 over the emitted blocks/edges
  as the behavior gate. `--check` compares both ratios + the fingerprint against
  bench/cfg/baselines.json; mirrors the scope-capture / python-scope harnesses.
- .github/workflows/ci-tests.yml: run the gate on every test job (build-free,
  alongside the existing scope-capture guards) so an O(n^2) re-regression fails CI.
- cfg-builder.ts: structural fix for the one real hotspot the bench surfaced —
  accumulate basic-block text as fragments joined once in finish(), instead of
  concatenating onto a growing string per coalesced statement (O(n^2) → O(n)).
  Behavior-identical (the CFG fingerprint + the AC1 snapshot are unchanged).

Measured (post-fix): time ratios straight-line ~1.3, many-functions ~1.0,
branchy ~1.1 (all sub-quadratic; a true O(n^2) would be ~4.0). cfgSideChannel
bytes scale linearly (~1.0-1.04). 60 CFG tests green; build clean.

* perf(ingestion): add memory + disk growth gates to the CFG benchmark (#2081)

Extend bench/cfg/measure.mjs beyond wall-time to the two other scalability
dimensions that matter at kernel scale:

- DISK growth: utf8 byte size of the serialized cfgSideChannel — exactly what a
  --pdg run writes onto every ParsedFile shard (durable store + parse cache).
- MEMORY growth: retained JS heap of the cfgSideChannel payload, measured by the
  release-delta method (heap held minus heap after dropping it) — robust to
  pre-existing garbage and dead-stable run-to-run. Needs `node --expose-gc`;
  without it the heap metric is null and its gate is skipped (local runs still
  work). ci-tests.yml now passes --expose-gc so the heap gate runs in CI.

Both gated on linear scaling in baselines.json (disk_bytes_budget / heap_budget
1.2-1.3). Measured: disk ~1.0-1.04, retained heap ~0.87-1.0 — both linear
(~1KB/function each; ~2MB heap / 1.6MB disk at 2000 functions, --pdg only).
Bumped REPS 7->15 to stabilize the noisier time signal and widened the coarse
time tripwire budgets (the disk/heap gates carry the tight regression detection).

* fix(ingestion): address tri-review + CFG-expert findings (#2081)

Corroborated findings from the tri-review (Codex + CE personas + GitNexus swarm
+ a CFG/program-analysis domain-expert lane). The OFF-path stays byte-identical;
all fixes are within the --pdg path or the benchmark.

- [Codex+CFG-expert] Exceptional `throw` edges now wire EVERY block in a try's
  protected region to the handler, not just the body ENTRY. A branched try body
  (`try { if (x) { use(t); } } catch`) previously left interior blocks with no
  path to `catch` — a taint false-negative into the handler for the M2 PDG pass.
- [Codex+CFG-expert] An unresolved labeled jump (a stacked outer label or a
  labeled non-loop block) now routes to the function EXIT instead of leaving a
  dangling sink — restores the single-exit invariant post-dominator/PDG
  computation needs.
- [Codex] computeChunkHash now folds pdgMaxFunctionLines/pdgMaxEdgesPerFunction
  into the chunk key (not just the pdg boolean), so a warm cache built under one
  cap is never served to a run with a different cap (#2038 class, extended to
  the budgets). Adds PdgCacheKey; boolean form kept for back-compat.
- [perf] visitTry resolves catch/finally in a single namedChild pass (the double
  `namedChildren.find` allocated two throwaway arrays).
- [adversarial] The bench `straight-line` scenario now runs at 2000->8000:
  output is a constant 4 blocks so disk/heap can't see the concat path, and at
  the old N a genuine O(n²) was masked by V8 cons-strings. Verified at the new N:
  the array-join impl ~1.0, a rope-optimized `+=` ~1.0 (correctly not flagged),
  a real O(n²) (re-join-every-append) ~3.8 — budget tightened 2.0->1.5.
- [adversarial+Codex] The bench `--check` now FAILS LOUDLY when run without
  `--expose-gc` instead of silently skipping the retained-heap gate.
- Doc: re-labeled the finally-bypass as a SOUNDNESS (false-negative) limitation
  tracked for M2, not mere "precision."

3 new regression tests (branched-try interior→handler, stacked-label→EXIT,
cap-fold key). 99 CFG tests pass; build clean; bench gate green.

* docs(parse-cache): clarify that SCHEMA_BUMP still invalidates caches once (#2099 F6)

The computeChunkHash comment claimed pdg-off warm caches "survive this
change untouched" — true for the key FORMAT, but misleading as an
upgrade-behavior promise: SCHEMA_BUMP 4→5 changes PARSE_CACHE_VERSION
and both stores hard-invalidate on it. Separate the two facts so the
next cache change isn't reasoned about from a false premise.

* fix(cfg): correct for-loop back-edge kinds when no increment clause (#2099 F5)

A for with a body but no increment emitted an unconditional
header→header 'loop-back' self-edge (a path that never executes the
body) while the real back-edge body→header was labeled 'seq'. Any
consumer identifying loops via reason='loop-back' picked the phantom
edge and excluded the body from the natural loop.

Gate the self-edge on the body being absent (the one case where the
header genuinely re-tests itself) and carry 'loop-back' on the body's
exits when they ARE the back-edge, matching visitWhile/visitForIn.

* fix(cfg): treat an empty catch clause as a real handler (#2099 F2)

visitTry keyed handler semantics off the traversal result — null for an
empty body, since visitSeq([]) returns null — instead of the syntactic
clause. An empty `catch {}` was therefore treated as NO catch: the
swallowed exception escaped to the outer handler/EXIT, the no-catch
re-propagation misfired past finally, and code after a try whose body
always throws became unreachable from ENTRY — a hard false-negative
source for the M2 taint pass, on an extremely common pattern.

Synthesize one empty block spanning the clause (entry == sole exit)
when the catch body traverses to null, before the protected region is
walked. Exception flow lands in it and rejoins the normal continuation;
all downstream wiring (handler selection, finally routing, the !catchRes
re-propagation gate) operates on the syntactically-correct shape.

* fix(cfg): guard CFG emission per element, not just per outer array (#2099 F4)

The cfgSideChannel guard checked only Array.isArray before casting to
FunctionCfg[] — its own comment promised a wrong-shape value would
'skip emission, not throw a TypeError mid-graph-build', but a malformed
ELEMENT sailed through. Worse, the obvious-looking failure shape never
throws at all: emitFileCfgs string-templates any edge endpoint into the
BasicBlock id and graph inserts are no-throw, so a non-integer endpoint
silently became a dangling 'BasicBlock:…:undefined' edge that degrades
the DB rel-pair COPY to row-by-row fallback inserts much later.

Layered fix matching house precedents (parsedfile-store reviver,
worker-side per-file catch): a per-element shape+content predicate
(arrays + integer edge endpoints) that warns and skips malformed
elements while valid siblings still emit, plus a per-file try/catch
backstop for shapes that genuinely throw (e.g. a null inside blocks).

* fix(parse-cache): drop emit-time edge cap from the pdg chunk key (#2099 F3)

pdgMaxEdgesPerFunction is applied exclusively in emitFileCfgs during
scope-resolution on the main thread — the worker never receives it
(workerData carries only pdg + pdgMaxFunctionLines), so the cached
worker output is byte-identical across cap values. Folding it into the
chunk key (added by a prior review round) only converted a free knob
into a repo-sized cost: every cap change forced a full re-parse and a
durable-store rewrite of unchanged data.

Keep pdg + maxFunctionLines (genuinely worker-visible, shape the cached
cfgSideChannel) and document the classification test in the PdgCacheKey
doc comment so the next option gets sorted deliberately: worker-shard
inputs go in this key; persisted-graph-only inputs belong in the
RepoMeta pdg stamp (F1). Chunks written under the old ns string miss
once and prune — no migration needed.

* fix(analyze): record pdg config in RepoMeta; force full writeback on mode flip (#2099 F1)

Running --pdg against an already-indexed repo silently persisted ~zero
CFG: incremental eligibility had no pdg term, RepoMeta recorded no
mode, and extractChangedSubgraph keeps only changed-file nodes — on a
no-change --pdg re-run every freshly built BasicBlock was dropped from
the written subgraph ('Incremental: changed=0', run succeeds, zero
rows). The converse flip left zombie mixed-coverage blocks only --force
could clean. Worse, a clean-tree flip hit the alreadyUpToDate fast path
and never ran the pipeline at all.

- RepoMeta gains an additive-optional pdg stamp ({maxFunctionLines,
  maxEdgesPerFunction}, resolved values; absent ≡ pdg-off, which covers
  every legacy meta). No INCREMENTAL_SCHEMA_VERSION bump — that would
  force a one-time full rebuild for everyone. The end-of-run meta is a
  fresh literal, so omitting the field on a pdg-off run is what clears
  the stamp after an on→off flip.
- pdgModeMismatch (pure, exported) compares the resolved triple; the
  flip check sits before the fast path and always logs its notice (not
  gated on options.force — --skills implies force with no message of
  its own), naming the .gitnexusrc pdg key that pins the mode.
- The full-rebuild branch now writes the incrementalInProgress dirty
  flag (toWriteCount: 0 sentinel) before the wipe whenever a prior meta
  exists, mirroring the incremental branch. This closes the crash
  window where a rebuild dying between the bulk load and saveMeta left
  meta/DB inconsistent and the fast path certified zombie (or missing)
  CFG rows indefinitely — and incidentally closes the same pre-existing
  hole for user --force runs. Recovery log reworded accordingly.

Tests: pdg-mode-flip.test.ts (real git + LadybugDB; primary assertion
is a direct BasicBlock table count — meta.stats aggregates
nondeterministic Community/Process rows) covering off→on, steady-state
fast path, on→off zombie cleanup, cap-change rebuild, and dirty-flag +
flip composition; pure-helper tests for default resolution and the
0=unlimited carve-out.

refactor(ingestion): delete shadow-mode parity harness (RING4-3, #944) (#2071)
Ring 4 retires the legacy call-resolution DAG. With the legacy resolver
gone (RING4-1 #942, RING4-2 #943), shadow mode has nothing to dual-run
against, so the remaining shadow-mode artifacts are dead code.

- Delete gitnexus-shared/src/scope-resolution/shadow/{diff,aggregate}.ts
  (pure parity comparison logic) and its gitnexus-shared barrel exports.
- Delete the static parity dashboard (gitnexus/shadow-parity-dashboard/),
  which also removes the last GITNEXUS_SHADOW_MODE reference in the repo.
- Delete the shadow-mode unit tests (gitnexus/test/unit/shadow/).
- Scrub stale doc comments referencing the shadow harness / parity
  dashboard / removed legacy run (csharp/php/python/typescript index.ts,
  evidence.ts, module-scope-index.ts).

Already removed by RING4-1/-2 (verified): the shadow harness source and
GITNEXUS_SHADOW_MODE env handling; no CI job published dashboard artifacts.

Historical parity records preserved per acceptance: the CHANGELOG entry
(#918, #923, #951, #972) and the ci.yml RING4-1 note remain. Last
documented parity state is that historical coverage — no live
.gitnexus/shadow-parity/ run data exists in-tree (runtime output only).

* fix(ingestion): reduce parse-phase memory for huge repos (#1983)

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).

bench/scope-capture/measure.mjs fingerprints emitCScopeCaptures over the

c-static-linkage-worker fixture (caller.c/lib.c/lib.h/local.c — 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),

Reduce the scope-resolution resident-memory floor and setup throughput on

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(cpp): resolve cross-namespace same-tail inheritance bases bridge-held (#1993) (#2005)
* fix(cpp): resolve cross-namespace same-tail inheritance bases bridge-held (#1993)

PR #1981's bridge fixed within-namespace same-tail heritage (NS::A::Inner vs NS::B::Inner). The residual: a cross-namespace same-tail base (NS1::A::Inner vs NS2::A::Inner) both key the namespace-omitted `A.Inner` in the qualifiedNames index, so resolveQualifiedInheritanceBase couldn't pick a winner and the deriving classes cross-wired (DB's EXTENDS bound to NS1's A::Inner).

Fixed bridge-held via the existing `namespacePrefix` sidecar — no qualifiedName invariant flip, no resolution-index re-keying: (1) tagNamespacePrefixes also tags defs declared directly in a namespace (the deriving NS1::DA), composed identically to the class-nested path; (2) resolveQualifiedInheritanceBase breaks a same-tail tie by preferring the candidate whose namespacePrefix matches the deriving class's. Two-phase lookup, UDC, brace-init, file-local linkage untouched (def.qualifiedName + index keys unchanged).

New cpp-cross-namespace-same-tail fixture + registry-primary test (in the cpp parity expected-failures). Verified: cpp suite 287/287 primary, 209 + 78 skips legacy — no regression; tsc + prettier clean.

* test(cpp): worker-path parity for #1993 cross-namespace tie-break + correct narrative

Add the missing parse-worker.ts parity describe for the #1993 cross-namespace
same-tail heritage tie-break, mirroring the #1982/#1995 worker siblings
(workerThresholdsForTest minFiles:1/minBytes:1, workerPoolSize:2, usedWorkerPool
guard, and the same NS1.DA→NS1.A.Inner / NS2.DB→NS2.A.Inner base assertions), and
register both worker test names in LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES['cpp']
(registry-primary-only, like the sequential entry). Closes the DoD sequential≡worker
gap flagged in the tri-review of PR #2005.

Also correct the fixture/test narrative: the pre-fix failure is a CROSS-WIRE (DB's
EXTENDS binds NS1::A::Inner via the refuse-on-tie scope-walk fallback), not a silent
miss — the empirical pre-fix run shows the edge exists but points at the wrong target.

* refactor(scope-resolution): type the namespacePrefix sidecar; regen cpp bench baseline (#1993)

F4 follow-up to #1993: declare `namespacePrefix?: string` on SymbolDefinition
(gitnexus-shared) and drop the six `as { namespacePrefix?: string }` casts in
walkers.ts / graph-bridge/ids.ts that #1993 introduced. Pure type-level — the `as`
assertions erase at compile time, runtime is byte-identical, and the field stays a
sidecar (no graph-node identity; the qualifiedName-keyed index is untouched).

Also regenerate the cpp scope-capture bench baseline: rebased onto main (now
carrying #1995's cpp fixtures), #1993 adds cpp-cross-namespace-same-tail, growing
the cpp-* corpus 272->273 and drifting the fingerprint d63ded6->6d6207ae. Pure
fixture-corpus drift — no scope-extractor change.

feat(vue): migrate Vue SFC to scope-based resolution (RFC #909 Ring 3, closes #940) (#1950)
* feat(vue): migrate Vue SFC to scope-based resolution (RFC #909 Ring 3, closes #940)

Adds `vueScopeResolver` and wires Vue into the scope-resolution pipeline
(`SCOPE_RESOLVERS`, `MIGRATED_LANGUAGES`). Vue's `<script>` / `<script
setup>` blocks are TypeScript — `emitVueScopeCaptures` extracts the script
block via the existing `extractVueScript` utility and delegates to
`emitTsScopeCaptures`, keeping grammar identity consistent with the cached
tree the parse-worker already builds.

- `languages/vue/captures.ts`     — `emitVueScopeCaptures`
- `languages/vue/import-target.ts` — `makeVueResolveImportTarget` (TS
  resolver + tsconfig path-alias support; explicit `.vue` imports
  resolve via the exact-path branch)
- `languages/vue/scope-resolver.ts` — `vueScopeResolver`
- `languages/vue/index.ts`         — barrel + known-limitations doc

- `languages/vue.ts`                  — `emitScopeCaptures` hooked up
- `scope-resolution/pipeline/registry.ts` — Vue entry added
- `registry-primary-flag.ts`          — `SupportedLanguages.Vue` added
  to `MIGRATED_LANGUAGES` (production default → registry-primary)

- `vue-composition-api` — `<script setup lang="ts">`, defineProps /
  defineEmits macros, cross-file TS imports, computed refs
- `vue-options-api`     — `defineComponent({methods, computed, data})`,
  this-based method calls, imported utility calls
- `vue-cross-file`      — composable functions returning class instances,
  multi-level import chains, UserModel/PostModel method calls

- `fieldFallbackOnMethodLookup: true` — Options API `this.X()` calls may
  not resolve through the type-binding layer (no formal class); fallback
  catches common patterns via declared field names.
- `allowGlobalFreeCallFallback: false` — Vue uses explicit imports;
  workspace-wide unique-name fallback would produce spurious edges for
  built-ins (ref, reactive, defineProps, …).
- Template expression calls intentionally out of scope: component-
  reference CALLS edges are already emitted by the legacy template
  extractor. Remaining template gaps tracked in #1647.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(vue): address P0/P1 review findings from #1950

## P0 #1 — missing scope-resolution hooks in vueProvider
`pass3CollectImports` early-returns when `interpretImport` is undefined,
producing zero IMPORTS and zero cross-file CALLS edges. Add the four
hooks to `vueProvider` in `vue.ts`:
  - `interpretImport: interpretTsImport`
  - `interpretTypeBinding: interpretTsTypeBinding`
  - `bindingScopeFor: tsBindingScopeFor`
  - `importOwningScope: tsImportOwningScope`
Also add `receiverBinding`, `mergeBindings`, `arityCompatibility`, and
`resolveImportTarget` to complete the scope-resolution contract.

## P0 #2 — template-component CALLS dropped when Vue is registry-primary
`isRegistryPrimary(Vue) → true` makes the main call-processor loop skip
Vue files entirely, silencing the inline `vue-template-component` CALLS
emitter at ≈L1506. Add a dedicated post-loop pass in `call-processor.ts`
that emits template-component CALLS for Vue files whenever Vue is
registry-primary. Update the stale `vue/index.ts` limitation comment to
reflect the new emit site.

## P1 #3 — worker-mode double-extraction → zero captures
In worker mode (≥15 files) the parse worker pre-extracts the `<script>`
block and passes `scriptContent` as `sourceText`. `emitVueScopeCaptures`
was calling `extractVueScript` a second time, getting null, and returning
`[]`. Fix: if extraction returns null and the content has no SFC block-
level markers (`<template`, `<style`), treat it as already-extracted
script text and delegate directly to `emitTsScopeCaptures`.

## Test assertion strictness
Replace all `toBeGreaterThanOrEqual(1)` assertions with exact `toBe(N)`
counts. IMPORTS counts reflect per-symbol scope-based edges (value imports
only; `import type` is not emitted as an IMPORTS edge). CALLS counts are
1 per single-call-site.

* feat(vue): template-derived edges + pipeline benchmark (#1950 review)

Addresses the reviewer's request for template edge attribution and a
performance benchmark.

## Template event-handler CALLS (`vue-template-callback`)
Add `extractTemplateEventHandlers` to `vue-sfc-extractor.ts`. Extracts
bare single-identifier handlers from `@event="methodName"` and
`v-on:event="methodName"` attributes. Inline expressions with arguments
or operators (`@click="toggle(item)"`) are intentionally excluded.

Wire into the dedicated registry-primary Vue template pass in
`call-processor.ts`. For each extracted handler name, `ctx.resolve`
finds the in-file Function/Method node and emits a CALLS edge with
`reason: 'vue-template-callback'`.

## Template attribute-binding ACCESSES (`vue-template-attribute`)
Add `extractTemplateAttributeBindings` to `vue-sfc-extractor.ts`.
Extracts bare single-identifier values from `:prop="varName"` and
`v-bind:prop="varName"` bindings. Member-access (`:key="post.id"`) and
literals are excluded by the identifier-boundary regex.

Wire into the same template pass. For each extracted variable, `ctx.resolve`
finds the in-file node and emits an ACCESSES edge with
`reason: 'vue-template-attribute'`.

## `vue/index.ts` limitations comment
Updated to accurately describe all three categories of template-derived
edges and explicitly document the complex-expression exclusions.

## Tests
Add 6 new assertions in `vue-scope.test.ts`:
- `@click="handleSave"` → CALLS `handleSave` (UserProfile.vue)
- `@select="onPostSelected"` → CALLS `onPostSelected` (App.vue composition)
- `@keyup.enter="addTodo"` → CALLS `addTodo` (TodoList.vue)
- `@loaded="onUserLoaded"` → CALLS `onUserLoaded` (App.vue cross-file)
- `:userId="currentUserId"` → ACCESSES `currentUserId` (App.vue composition)
- `:posts="allPosts"` → ACCESSES `allPosts` (App.vue composition)

Add `vue` entry to `LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES` in
`helpers.ts` documenting which assertions are registry-primary-only
(IMPORTS cardinality, template-derived edges, `<script setup>` export).

## Benchmark
Add `vue-pipeline-benchmark.test.ts` (gated by `GITNEXUS_BENCH=1`).
Generates N-component synthetic repos (10 / 25 / 50 / 100) and asserts
that wall-clock and node counts scale sub-quadratically with component
count, guarding against O(n²) regressions in the template extraction
or scope-resolution passes.

* feat(vue): BINDS_EVENT_HANDLER/EMITS_EVENT edges via ScopeResolver hook

Per maintainer feedback on PR #1950:
- Do not edit call-processor.ts (will be removed when all languages migrate)
- Model Vue component-event system with dedicated edge types to avoid CALLS
  noise in deep component hierarchies (per contributor discussion)

Changes:
- gitnexus-shared: add BINDS_EVENT_HANDLER and EMITS_EVENT to RelationshipType
- vue-sfc-extractor: add extractComponentEventBindings, extractNativeElementEventHandlers,
  and extractScriptEmitCalls
- ScopeResolver contract: add optional emitPostResolutionEdges hook
- run.ts: wire emitPostResolutionEdges after emitImportEdges
- vue/scope-resolver: implement emitPostResolutionEdges emitting:
    1. CALLS (vue-template-component) — PascalCase component File refs
    2. CALLS (vue-template-callback) — @event on native HTML elements
    3. BINDS_EVENT_HANDLER (vue-event: @name) — @event on component elements;
       source = handler fn in parent, target = child component File (not CALLS)
    4. EMITS_EVENT (vue-emit: name) — emit() calls; self-loop on component File,
       joinable with BINDS_EVENT_HANDLER via Cypher for impact tracing
    5. ACCESSES (vue-template-attribute) — :prop="var" bindings
- call-processor.ts: revert dedicated Vue post-loop pass; moved to scope resolver
- Tests and parity expected-failures updated accordingly

* fix(vue): close review gaps in scope/parity extraction

Resolve the new PR #1950 review findings by widening Vue scope context to include TS/JS import closures, fixing BINDS_EVENT_HANDLER endpoint assertions, hardening emit/event extraction to avoid comment/property false positives, supporting kebab-case component tags, and ensuring parity runs include vue-scope suites.

* fix(vue): address second review round — regex safety, emit coverage, arch

Closes items raised in the Jun 2 review comment on PR #1950.

Correctness fixes:
- ReDoS mitigation: bound attribute-capture spans to [^>]{0,512}? in all
  three template tag regexes to prevent pathological backtracking.
- Kebab-case misclassified as native: added (?![A-Za-z0-9-]) negative
  lookahead to NATIVE_TAG_RE so <post-list> is no longer split as native
  tag `post` with attrs `-list ...`.
- Hyphenated event names dropped: widened TAG_EVENT_RE from [\w:.]+ to
  [\w:.-]+ so @user-loaded and @update:model-value are captured.
- this.$emit silently dropped: collectBareEmitEventNames now allows
  this.$emit(...) by looking back past the '.' to verify preceding token
  is exactly `this`; socket.emit etc. remain blocked.
- Event names with colon rejected: extended validator to accept
  update:modelValue and update:model-value patterns.

Architecture fix:
- Moved collectVueScopeFilePaths out of shared phase.ts into a new
  collectScopeContextPaths optional hook on ScopeResolver, keeping shared
  pipeline code language-agnostic. vueScopeResolver implements the hook.
- Fixed memory leak: preExtractedByPath cleanup now iterates filePaths
  (all context files) not just primaryFilePaths (only .vue files).

Cleanup:
- Removed unused extractTemplateEventHandlers and duplicate EVENT_HANDLER_RE.
- Fixed skipped comment numbers in emitPostResolutionEdges (1,2,4,5,6 -> 1-6).
- Updated vue/index.ts: four categories -> five (added EMITS_EVENT).
- Fixed gitnexus-shared EMITS_EVENT JSDoc to reflect File->File reality.

Tests: 7 new unit tests covering hyphenated events, this.$emit, kebab-case
native-tag exclusion, and update:modelValue event name validation.

* fix(vue): eliminate double file-read and per-file template re-scans

Two performance fixes from the self-review pass:

1. **No more double read of .vue files in phase.ts**: primary files were
   previously read once for `collectScopeContextPaths` (via
   `entryFileContents`) and again in the blanket `readFileContents(filePaths)`
   call. Now the primary-file map is passed directly and only the extra
   context files (TS/JS import closure) require a second I/O round-trip.

2. **Single template parse per .vue file in emitPostResolutionEdges**:
   previously each of the five extractor functions (components, native
   handlers, component event bindings, emit calls, attribute bindings) ran
   `TEMPLATE_RE.exec(content)` independently — five full-file scans per
   `.vue` file. Replaced with a new `extractVueTemplateEdgeData` batching
   helper that parses the template and script blocks once and feeds all five
   extractors from the pre-extracted content. emitPostResolutionEdges now
   calls a single function and destructures the results.

* fix(parity): exclude TypeScript HOC/HOF/JSX scope-resolver tests from legacy DAG parity gate

Three test files introduced in prior PRs exercise scope-resolver-only
correctness wins: HOC-wrapped const declarations, HOF-callback caller
attribution, and JSX-as-call CALLS edges. The parity runner's
${slug}-*.test.ts glob now picks them up, causing typescript [legacy]
failures in CI.

Fix: convert each file to use createResolverParityIt('typescript') and
register all 26 legacy-failing test names in
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.typescript with explanatory
comments. Legacy mode: 11+11+4 tests skipped, zero failures.
Registry-primary mode: all 37 tests pass as before.

fix(ingestion): fully-qualified nested-type identity for C++/Ruby — structure (#1978) + resolution (#1982) (#1981)
* fix(ingestion): qualify nested-type node identity for C++/Ruby (#1978)

Nested types sharing a tail name in one file — C++ `Outer::Inner` vs
`Other::Inner`, Ruby `Outer::Inner` vs `Other::Inner` modules — silently merged
into a single graph node keyed by the simple tail (`Struct:file:Inner`),
cross-wiring their methods/properties onto one owner.

Key class-like type nodes (Class/Struct/Interface/Enum/Record) by their
normalized fully-qualified path (`Struct:file:Outer.Inner`) instead of the
simple name. Gated per-language by a new `qualifiedNodeId` config flag
(default false → byte-identical for every other language); enabled here for
C++ and Ruby.

- class-types.ts / generic.ts: `qualifiedNodeId` flag on ClassExtractor + config
- ast-helpers.ts: findEnclosingClassInfo gains an optional getQualifiedOwnerName
  hook + EnclosingClassInfo.qualifiedClassId, so member-owner edges resolve to
  the qualified class node id (owner id == node id by construction)
- parsing-processor.ts + parse-worker.ts: flag-gated qualified node-id + owner
  edges on both the sequential and worker parse paths (incl. routed properties)
- call-processor.ts: same qualifier in the routed-property pre-pass (lockstep
  with the worker `kind === 'properties'` block)
- configs/c-cpp.ts, configs/ruby.ts: qualifiedNodeId: true

Method/Property node ids stay simple-qualified; only type nodes get the
qualified id.

Deferred to a resolution-side follow-up: Ruby SAME-TAIL routed-property/mixin
owner identity under registry-primary (`emitRubyMixinEdges` keys owners by the
simple tail name, last-wins); and Rust inherent-impl methods (impl_item is not
a typeDeclaration — its #1978 test is describe.skip).

Tests: same-tail collision fixtures + #1978 resolver tests for C++/Ruby
(positive owner identity, R7), a worker-path parity block, and an unambiguous
nested attr_accessor case; the C++ #1975 out-of-line test updated to assert
qualified-id distinctness (forward-decl + out-of-line now unify). Verified
green on both parity legs, the worker path, and tsc.

* test(ingestion): scope #1978 resolver tests to registry-primary leg; fix lint

- helpers.ts: exclude the new #1978 C++/Ruby resolver tests from the legacy
  parity leg (LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES). They PASS on legacy
  too — the fix lives in the SHARED structure phase, not the legacy resolution
  path — so this is a deliberate registry-primary-only scoping (not a legacy
  gap), keeping the legacy path untouched and uncoupled from the new
  node-identity behavior.
- rust.test.ts: drop the `eslint-disable vitest/no-disabled-tests` directive.
  That rule isn't configured in this repo, so eslint errored "Definition for
  rule 'vitest/no-disabled-tests' was not found" and failed `quality / lint`.
  The describe.skip needs no disable directive.

* fix(test): satisfy CI for the new #1978 fixtures (format + golden + fingerprint)

Adding the {cpp,ruby,rust}-nested-tail-collision fixtures changed the
lang-resolution corpus, which the scope-capture golden snapshots and the
fingerprint baselines gate on. These are pure fixture-corpus additions —
#1978 does not touch the scope-capture phase (captures.ts / emit*ScopeCaptures
are unchanged). Verified: the regenerated ruby/rust golden diffs are
additive-only (no existing fixture's capture digest changed), so the cpp/ruby/
rust fingerprint drift is solely the new fixtures.

- prettier --write test/integration/resolvers/{ruby,rust}.test.ts
- regenerate ruby/rust captures-golden snapshots (UPDATE_GOLDEN=1; +1 fixture each)
- rebaseline cpp/ruby/rust scope-capture fingerprints (bench/scope-capture/baselines.json)

* refactor(ingestion): extract shared qualified-name normalizer (#1982)

Move normalizeQualifiedName/splitQualifiedName out of class-extractors/
generic.ts into utils/qualified-name.ts so the structure-phase
buildQualifiedName, the scope-resolution inheritance resolver, and the
per-language capture emitters can all key against ONE normalizer. A raw
'::' qualifier must normalize to the exact '.'-joined key the
QualifiedNameIndex already holds, or the qualified lookup silently misses
(the #1982 resolution-side foundation). Pure relocation — byte-identical
function bodies; tsc clean; existing C++ nested-collision tests green.

* fix(ingestion): resolve same-tail C++ nested-type heritage to the correct qualified node (#1982)

Registry-primary C++ inheritance (preEmitInheritanceEdges -> resolveInheritanceBaseInScope)
resolved a same-tail nested base by its SIMPLE TAIL with first-wins, so
`struct DerivedB : Other::Inner` mis-resolved EXTENDS to Outer.Inner (the wrong
sibling; 0 dangling, so undetected). The namespace qualifier was discarded at the
C++ inheritance capture.

Fix (additive, qualified-first):
- ReferenceSite gains an optional `rawQualifiedName`; the C++ inheritance capture
  emits `@reference.qualified-name` (qualifier-preserving, template-stripped:
  Other::Inner, ns::Base<T> -> ns::Base) only when the base is qualified, registered
  as a sub-tag so it can't shadow the `@reference.inherits` anchor.
- resolveInheritanceBaseInScope resolves the qualifier against the full-path
  QualifiedNameIndex FIRST (which already carries Outer.Inner / Other.Inner keys from
  the structure phase), with progressive-prefix lookup for relative bases and
  refuse-on-tie, falling through to the existing simple-tail walk on miss — so
  unqualified bases and the single-candidate cross-file case are unchanged.

Registry-primary cpp.test.ts 278/278 (incl. worker-path: rawQualifiedName survives
worker serialization). Legacy leg unaffected (207 pass / 71 skip) — the new
resolution-side assertions are registry-primary-only via helpers.ts. tsc clean.

* fix(ingestion): resolve same-tail Ruby mixin/attr_accessor owners to the correct qualified node (#1982)

emitRubyMixinEdges keyed its owner map by the SIMPLE tail (def.qualifiedName
split-popped) with last-wins, and the __heritage__/__property__ markers carried
only the immediate owner name — so `module Outer; class Inner` and
`module Other; class Inner` collapsed onto one `Inner` key and cross-wired their
include/attr_accessor edges onto whichever Inner was processed last.

Fix (lockstep, full-qualified):
- ruby/captures.ts: build the marker owner from the FULL enclosing class/module
  chain (buildEnclosingQualifiedName walks all ancestors, normalizing the compact
  `class Outer::Inner` scope_resolution form via the shared splitQualifiedName) so
  the marker owner byte-matches the resolution def's qualifiedName.
- ruby/scope-resolver.ts: key graphIdByName by the full def.qualifiedName instead
  of the simple tail. Top-level owners/mixins are unchanged (full == simple).

Registry-primary ruby.test.ts 142/142 incl. a new worker-path block (the deferred
note's duplicate-edge concern: markers survive worker serialization, exactly one
HAS_PROPERTY per attr). Legacy leg unaffected (136 pass / 6 skip) — new assertions
registry-primary-only via helpers.ts. tsc clean.

* test(ingestion): rebaseline #1982 golden/fingerprint + lint/format sweep

Cross-cutting verification artifacts for the #1982 same-tail resolution fix:
- ruby capture golden regenerated: ONLY the ruby-nested-tail-collision fixture
  drifts (+10 capture groups from its new include/attr_accessor + the now
  full-qualified __heritage__/__property__ marker owner). All other ruby fixtures
  byte-identical (proves the owner-qualification is localized to nested owners).
- bench/scope-capture/baselines.json: rebaseline cpp + ruby fingerprints (the only
  two that drift; 12 other languages byte-identical). cpp = additive
  @reference.qualified-name capture; ruby = the localized owner change. Provenance
  notes record both. scaling linear (~1.0), 14/14 PASS.
- generic.ts: drop the now-unused normalizeQualifiedName import (lint error).
- walkers.ts / ruby.test.ts: prettier formatting.

Verified: cpp 278/278 + ruby 142/142 (registry-primary), both legacy legs clean
(skips registry-primary-only assertions), go/java/csharp 542 (cross-language
regression — the qualified-first branch is gated on rawQualifiedName, set only by
C++, so non-C++ inheritance resolution is unchanged). tsc + eslint(0 errors) + prettier clean.

* fix(ingestion): resolve nested Ruby mixin included by short name (#1982)

emitRubyMixinEdges keyed graphIdByName by the full def.qualifiedName on the
owner side, but the __heritage__ marker carries the mixin target as the bare
written name (arg.text). A nested mixin module included by its short name
(include Loggable where it is App::Loggable) missed the full-qn map and its
IMPLEMENTS edge was silently dropped (0 dangling, undetectable). The shipped
same-tail fixture used only top-level mixin modules, so CI stayed green.

Add a secondary simple-tail fallback map consulted only when the full-qn mixin
lookup misses; owner lookups stay full-qn so same-tail owner disambiguation is
preserved. Characterization test + fixture (registry-primary only); golden
regenerated additively.

* fix(ingestion): normalize qualified Ruby mixin arg in heritage marker (#1982)

`include Outer::Mixin` embedded the raw `Outer::Mixin` into the ':'-delimited
__heritage__ marker, so the `::` collided with the field separator and
emitRubyMixinEdges mis-split it (className became empty), dropping the IMPLEMENTS
edge. Normalize the mixin arg via splitQualifiedName(...).join('.') before emit
so the marker carries the dotted form, which both parses correctly and matches
the mixin def's qualifiedName. Simple names are unchanged (no golden drift).

* fix(ingestion): resolve C++ same-tail nested heritage inside a namespace (#1982)

A namespace-nested C++ type's scope-model qualifiedName carried its enclosing
CLASS chain (A.Inner) but dropped the enclosing NAMESPACE, while the
structure-phase graph node is keyed by the full path (NS.A.Inner). resolveDefGraphId's
qualifiedKey therefore missed and fell back to simpleKey('Inner'), collapsing
same-tail nested bases across sibling namespace members — DB : B::Inner pointed
at NS.A.Inner. The shipped fixture was top-level only, so it could not catch this.

Fix without disturbing the qualifiedName-keyed resolution index (an earlier
attempt that rewrote qualifiedName regressed brace-init / UDC / two-phase
namespace resolution): tagNamespacePrefixes records each namespace-nested def's
enclosing-namespace prefix on a sidecar field, and resolveDefGraphId retries the
node lookup with the namespace-prefixed key before the simpleKey fallback. The
helper is language-agnostic (acts only on Namespace scopes) and opt-in — only the
C++ provider calls it. Namespaced fixture + sequential & worker tests
(registry-primary only). All 280 cpp resolver tests pass; tsc clean.

* test(ingestion): worker-path parity for Ruby mixin IMPLEMENTS + C++ DerivedA (#1982)

The Ruby worker-path parity block asserted only attr_accessor (HAS_PROPERTY);
add an IMPLEMENTS assertion so a dropped/cross-wired mixin owner on the worker
path is caught (the __heritage__ marker owner must survive serialization). The
C++ worker heritage block asserted only DerivedB; add a DerivedA assertion with
a toHaveLength(1) duplicate guard. Registry-primary only.

* fix(ingestion): distinct Rust same-tail nested-mod inherent-impl ownership (#1982)

Rust methods live in `impl Inner` blocks, and findEnclosingClassInfo keyed the
inherent-impl owner by the target's RAW tail (`Impl:lib.rs:Inner`), so two
same-tail `impl Inner` blocks under different mods (mod outer / mod other)
collapsed onto ONE Impl node and their methods cross-wired. The shipped fixture
test for this was skipped/deferred.

Qualify an UNSCOPED inherent-impl target by its enclosing `mod_item` scope
(`outer.Inner`) in BOTH the owner walk (ast-helpers.qualifyRustImplTargetByModScope)
and the Impl-node materialization (parsing-processor + parse-worker, lockstep) so
the owner edge and node id agree byte-for-byte. Gated on the Impl label +
impl_item + an unscoped type_identifier target — Rust-impl-exclusive, so C++/Ruby
and the rust captures golden are untouched; a SCOPED `impl a::Inner` keeps its
full raw text (#1975, unchanged). The previously-skipped distinct-ownership test
is now active and passing; rust 170/170, cpp+ruby+golden 437/437, tsc clean.

Done in-PR at maintainer request (was deferred as a follow-up). Addresses PR #1981

normalizeQualifiedName (behaviorally equivalent for C++ qualified-identifier

HERITAGE_PREFIX (was function-local — asymmetric with no behavioral effect).

buildEnclosingQualifiedName (ruby/captures.ts). Behavior-preserving.

U8 (P3): a root-anchored C++ base ": ::A::Inner" names the GLOBAL type, but
resolveQualifiedInheritanceBase prepended the deriving class's enclosing

* test(ingestion): rebaseline ruby+cpp scope-capture fingerprints for new #1982 fixtures

The four new fixtures (ruby-nested-mixin-shortname, ruby-qualified-mixin,
cpp-namespaced-collision, cpp-global-base-anchor) grow the lang-resolution
corpus, drifting the ruby and cpp order-independent capture fingerprints.
Verified purely additive: the ruby captures golden shows only the two new
fixtures added (existing byte-identical), and removing the two cpp fixtures
reverts the cpp fingerprint to the prior baseline (so the U3/U6/U8 code changes
are scope-resolution / behavior-preserving, not capture-emission). measure.mjs

* fix(rust): scope-resolution coverage gaps — F66,F68,F71,F72,F73 (#1934)

* fix(rust): reviewer fixes — macro namespace, revert pattern:(_), drop variadic

* fix(rust): wire macro resolution end-to-end + materialize unions (#1974 review)

Addresses the outstanding #1974 review (second batch). Per maintainer
decision, F72 is FULLY WIRED rather than documented capture-only.

F72 macro — was a capture-only no-op (@reference.macro dropped downstream):
- gitnexus-shared: add 'macro' ReferenceKind + Reference.kind; add
  MACRO_KINDS (['Macro']) and a MacroRegistry that resolves a macro
  invocation ONLY to a macro_rules! definition — never a same-named free
  function (the disjoint-namespace guarantee the review required).
- scope-extractor: referenceKindFromAnchor @reference.macro -> 'macro';
  normalizeNodeLabel 'macro' -> Macro.
- resolve-references: route 'macro' sites through MacroRegistry.
- emit-references / graph-bridge edges: 'macro' -> USES (kept out of the
  CALLS keyspace, which denotes function/method dispatch).
- node-lookup isLinkableLabel: Macro is linkable, bridging the registry
  def to the legacy @definition.macro graph node.
- rust query: capture macro_rules! as @declaration.macro; fix the scoped
  macro arm to capture the tail identifier, not the full path (P3).

F71 union — the @declaration.struct scope capture had no graph node to
resolve to (legacy RUST_QUERIES never captured union_item):
- legacy query: capture union_item as @definition.struct so the union is
  materialized as a Struct node and is genuinely resolvable.
- query.ts: document the deliberate union->Struct downgrade rationale.

Tests:
- rust.test.ts (parity-gated): pipeline-level union resolution + macro
  resolution (USES to the Macro, exactly one CALLS to fn, none to Macro).
  Macro resolution is registry-primary-only -> listed in
  LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES['rust'].
- rust-coverage.test.ts: scoped-macro tail + macro-def capture assertions;
  reframed as capture-layer only, pointing at the pipeline tests.
- new fixtures rust-macro, rust-union.

F73: dropped from baselines.json _note (variadic was never implemented).

Rebaselined the rust capture golden + scope-capture fingerprint
(a5fdff2c..., scaling ~0.99, fixture_count 126).

feat(progress): add per-language progress reporting to scope-resolution phase (#1813)
* feat(progress): add per-language progress reporting to scope-resolution phase (#1741)

The scope-resolution phase (which can run 74+ minutes on large Java/Kotlin
repos) previously emitted zero progress updates, causing the CLI progress bar
to freeze at ~49% with a stale "Parsing code" label — making users think
the tool was stuck.

- Add `scopeResolution` to PipelinePhase type and PHASE_LABELS
- Add `onProgress` callback to `runScopeResolution` with per-file updates
  during the extract loop and sub-phase boundary markers (building scope
  model, resolving references, emitting edges)
- Wire progress through `scopeResolutionPhase` with pre-counted file totals,
  per-language labels, and pipeline-wide percent mapping (90-95 internal)
- Bump mro/communities/processes percent ranges to 95-100 to maintain
  monotonic progress after scope resolution
- Add `scopeResolution` to mro's deps (latent ordering fix: mro reads
  EXTENDS edges that scope resolution writes via preEmitInheritanceEdges)

* fix(progress): clamp overallRatio, fire final extract event, fix mro @deps JSDoc

- Clamp overallRatio to [0,1] so percent never exceeds 95 when
  readFileContents drops files (langFileCount < totalScopeFiles)
- Fire onProgress for the last file in the extract loop even when
  files.length is not divisible by progressInterval
- Update mro @deps JSDoc to include scopeResolution

* fix(progress): ensure bar redraws at every state transition

- Fire initial 'extracting' event at file 0 so the sub-phase label
  appears immediately, not after progressInterval files
- Emit a completion event at percent 95 when scope resolution finishes
  so the bar definitively reaches the phase ceiling before mro starts

* feat(progress): improve UX with human-readable elapsed, language counter, cleaner labels

- Format elapsed time as "5m 12s" / "1h 20m" instead of raw "(312s)"
  for all pipeline phases (CLI-wide improvement)
- Add language counter "[1/3]" to scope-resolution detail so users
  know how many languages remain and which is active
- Rename sub-phases for clarity: "building scope model" → "analyzing
  types", "emitting edges" → "linking symbols"
- Remove nested parentheses from detail strings for cleaner display
- Expand scope-resolution percent range from 5 to 8 points (90-98
  internal → 54-59% display) for more visible bar motion
- Re-allocate mro (98), communities (98-99), processes (99-100)

* feat(progress): typed sub-phases, i18n locales, and test coverage

- Extract ScopeResolutionSubPhase union type with exhaustive switch
  guard so adding a sub-phase without updating phase.ts is a compile
  error
- Add scopeResolution key to en and zh-CN locale files so the web UI
  shows translated labels instead of raw message fallback
- Extract formatElapsed to its own module with 7 boundary-value tests
  (0s, 59s, 60s, 3599s, 3600s, 3661s, 7323s)
- Add runScopeResolution onProgress integration test proving sub-phase
  order (extracting → analyzing types → resolving references → linking
  symbols) and the 0-file early-return path

* fix(cpp): thread call-site types into qualified member lookup (#1632)

Widen Callsite (arity optional, add argumentTypes) and add optional
callsite?: Callsite to ScopeResolver.resolveQualifiedReceiverMember.
receiver-bound-calls.ts passes the ReferenceSite through structurally;
resolveCppQualifiedNamespaceMember forwards it to narrowOverloadCandidates
along with cppConversionRank, enabling exact-type and conversion-rank
disambiguation across inline-namespace children.

Behavior change:
- outer::foo(42) where v1 declares foo(int) and v2 declares foo(double)
  now resolves to v1::foo (was: 0 edges, conservatively suppressed).
- Same-name same-normalized-signature (e.g. foo(int) vs foo(long)) still
  suppresses at 0 edges via isOverloadAmbiguousAfterNormalization.
- ADL using-import path (resolveAdlCandidates) unchanged — passes no
  callsite, narrowing degrades to existing pass-through behavior.

Closes #1632. Part of #1564.

* fix(cpp): update legacy parity expected-failure list for #1632

- Remove stale expected-failure entry for old diff-sigs test name
  (test now expects 1 edge; legacy DAG also emits 1 edge)
- Add entry for normalized-signature ambiguity (int vs long) test
- Rename describe block from 'conservative suppress' to
  'distinct signatures resolved via call-site types'

Verified both modes:
  REGISTRY_PRIMARY_CPP=1: 241/241 passed

change introduced when FieldRegistry moved from last-wins to append-order
storage (ce-code-review finding #2).

* test(scope-resolution): extend Step 2 perf contract to implicit-self, MRO, field paths

Adds three sibling tests under the Step 2 perf contract describe block, each
asserting defs.byId.values() does NOT execute when ownedMembersByOwner is wired:

- 2-level MRO chain (Child extends Parent, save resolves on Parent at depth 1)
- FieldRegistry read via Step 2 (property lookup, separate registry path)

Pins the perf invariant on every distinct entry into walkReceiverTypeBinding
so a regression bypassing the hook on any sub-path now fails CI immediately
(ce-code-review finding #8).

* test(resolve-references): cover arity-overload filtering via resolveReferenceSites

Pins the orchestration-layer wiring of providers.arityCompatibility:
hook returns [save(arity 1), save(arity 2)], referenceSite.arity = 1,
arityCompatibility verdicts 'compatible'/'incompatible' by parameterCount,
exactly one reference emitted with toDef = the arity-1 overload.

registries.test.ts already covered arity at the buildMethodRegistry level;
this adds the missing entry-point check that resolveReferenceSites threads
providers correctly through to lookupCore.Step5 (ce-code-review finding #10).

* test(resolve-references): add hook-on vs hook-off parity test

Runs resolveReferenceSites twice on the same fixture (Parent.save method
hit + Child.name field hit, Child extends Parent MRO chain) — once with
ownedMembersByOwner wired to a synthetic registry, once with the hook
absent so collectOwnedMembers takes the defs.byId fallback. Asserts:

- stats are identical (sitesProcessed / referencesEmitted / unresolved)
- referenceIndex.bySourceScope entries have equal length
- toDef sets are equal
- each per-site reference (including evidence and depth) is .toEqual

Locks the semantic-parity claim in code while both paths still exist.
Will be removed alongside the fallback in finding #1 (ce-code-review #3).

* test(typescript): probe Step 2 MRO walk against ambient (declare class) base

Adds typescript-ambient-base-class fixture with an export declare class
AmbientBase + Derived extends AmbientBase and a call site d.ambientMethod().
Integration assertions:

- Both classes are detected
- EXTENDS edge Derived → AmbientBase emitted
- CALLS edge to ambient.ts:ambientMethod resolved via MRO walk

Probes the ce-code-review #6 concern that ambient-only owners (whose
bodies are never parsed) might be silently skipped by Step 2 after the
owner-keyed lookup change. Result: the call resolves correctly — the
method signature inside the declare class body still flows through
reconcileOwnership into model.methods, so the hook returns the right
ancestor hits. Residual risk is empirically closed.

* feat(scope-resolution): route nested types via owner-keyed TypeRegistry

Closes the Step 2 contract footgun where 'hook returns [] = authoritative
miss' silently dropped any owned def whose NodeLabel was outside the
method/field if-chain in reconcileOwnership.

- TypeRegistry: add nestedByOwner Map + lookupAllByOwner(owner, simple)
  + registerByOwner(owner, simple, def). Mirrors MethodRegistry/
  FieldRegistry shape; cleared with the rest on cascade clear.
- reconcileOwnership: route class-like NodeLabels (Class/Interface/Enum/
  Struct/Union/Trait/TypeAlias/Typedef/Record/Delegate/Annotation/
  Template/Namespace) via types.registerByOwner. New nestedTypesRegistered
  stat. Idempotent skip via nodeId match.
- validateOwnershipParity: extend the I9 invariant check to nested types.
- lookupOwnedMembersByOwner: merge methods + fields + nested-type hits;
  short-circuit when any one source contributes the full result.

Unblocks future receiver-MRO registries that need to resolve 'Outer.Inner'
through the receiver's type-binding chain (ce-code-review finding #5a).

* refactor(scope-resolution): make ownedMembersByOwner required; delete byId fallback

Per ce-code-review finding #1, the optional-hook design encoded a silent
O(|defs|) perf cliff into the type system: any RegistryContext built
without the hook regressed Step 2 to scanning every def per probe with
no warning. Production wires the hook unconditionally; the fallback was
exercised only by tests.

- RegistryContext.ownedMembersByOwner: required, returns readonly
  SymbolDefinition[] (no | undefined). Implementations MUST return [] on
  authoritative miss.
- collectOwnedMembers in lookup-core.ts collapses to a one-line forward
  to the hook; the defs.byId.values() scan and simpleNameOf helper are
  deleted (simpleNameOf had no other consumers).
- ResolveReferencesInput.ownedMembersByOwner: required to match.
- Tests: drop three fallback-path tests (registries Const fallback,
  resolveReferenceSites no-hook fallback, resolveReferenceSites Const-
  undefined fallback) and the hook-vs-fallback parity test added by
  finding #3. makeCtx in registries.test.ts now defaults to a real
  owner-keyed scan over the test fixture defs so tests that don't care
  about the hook keep working.

* perf(free-call-fallback): cache global callables by simple name once per pass

pickUniqueGlobalCallable scanned scopes.defs.byId.values() on every
free-call fallback site. After PR #1656 fixed Step 2, this scan became
the dominant remaining O(|defs|) hot path on large repos (ce-code-review
finding #4).

- buildGlobalCallableIndex builds a Map<simpleName, SymbolDefinition[]>
  over scopes.defs once at the top of emitFreeCallFallback. Same filter
  the per-site scan applied: Function / Method / Constructor, keyed by
  the last .-segment of qualifiedName.
- pickUniqueGlobalCallable consumes the prebuilt index via O(1) Map.get
  instead of iterating every def. Per-site complexity drops from
  O(|defs|) to O(|defs with this simple name|).
- Cost: O(|defs|) once per pass instead of O(|defs| * |free-call sites|).

Subsequent narrowing (arity, conversion-rank) and the model-side fallback
(model.symbols.lookupCallableByName + model.methods.lookupMethodByName)
are unchanged.

* chore(autofix): apply prettier + eslint fixes via /autofix command

* ci: trigger build

feat(cpp): migrate C++ to scope-based resolution model (#938) (#1520)
* fix(cpp): complete scope-resolution parity

* fix(ci): resolve formatting, lint errors for PR #1520

- prettier: format arity-metadata.ts, captures.ts, index.ts
- eslint: rename unused HEADER_GLOB to _HEADER_GLOB
- eslint: replace unsafe parser.parse() with parseSourceSafe()
- eslint: suppress intentional console.warn/log in sync.ts
- eslint: remove unused _it import alias in cpp.test.ts

* fix(ci): complete formatting, lint, and typecheck fixes

- prettier: format call-processor.ts, imported-return-types.ts,
  include-extractor.test.ts, cpp-captures.test.ts, cpp-imports.test.ts
- eslint: suppress intentional console.warn in manifest-extractor.ts
- typecheck: restore 'thrift' in ContractType union (was accidentally
  removed) and add thrift case to exhaustive switch in manifest-extractor

* fix(ci): revert unintended group module changes that broke tests

Restore types.ts, config-parser.ts, matching.ts, sync.ts, and
manifest-extractor.ts to upstream/main versions. The original commit
accidentally removed fields (thrift, workspace_deps, exclude_links_paths,
exclude_links_param_only_paths) from DetectConfig/MatchingConfig/ContractType
which are still referenced by matching.test.ts, config-parser.test.ts,
sync.test.ts and other integration tests.

This PR's scope is C++ scope-resolution parity only — group module
type definitions and logic should remain unchanged.

* fix(codeql): address security and quality alerts

- arity-metadata.ts, interpret.ts: replace single-pass template strip
  regex (/<[^>]*>/g) with a while-loop to fully handle nested templates
  like Map<List<int>> — resolves 'Incomplete multi-character sanitization'
- cpp.test.ts: remove unused vitest 'it' import since the file defines
  its own 'it' via createResolverParityIt — resolves 'Assignment to constant'
- include-extractor.test.ts: use fs.mkdtempSync() instead of predictable
  os.tmpdir()+Date.now() paths — resolves 'Insecure temporary file'
- interpret.ts: remove redundant 'name !== undefined' check (already
  guaranteed by early return) — resolves 'Comparison between inconvertible types'

* review: address Claude review findings on PR #1520

- Findings 1-3 (BLOCKERS): restore include-extractor.ts and its test to
  the main baseline. Block-comment fallback regression, suffix-resolve
  false-positive suppression, and the four deleted regression tests
  (#3-#6) are now back. These changes were unrelated to C++ scope
  parity and should not have been in this PR.

- Finding 4 (MAJOR, partial): revert COMPOUND_RECEIVER_MAX_DEPTH 6 to
  4. No C++ test exercises depth > 4 (cpp-chain-call uses a 2-hop
  chain), so the bump risked silent regressions on other migrated
  languages without justification. The wildcard-origin propagation in
  imported-return-types.ts is retained — C++ #include and using
  namespace both emit wildcard-origin bindings (cpp/import-decomposer
  .ts:40,90), so wildcard propagation is causal to C++ parity.

- Finding 6: tighten write-access dedup test with exact per-field
  counts (nameWrites = 2, addrWrites = 1) instead of total-count + sub
  string containment, so a regression in one of the two name writes
  can no longer be masked.

- Finding 8: skipped. Box-drawing characters in cpp/query.ts comments
  match the established convention used in csharp/java/php query
  files.

Finding 5 (int/long normalization tie-breaker) left as documented
follow-up — proper fix requires resolver-level tie-breaker logic and
risks regressing other arity-matching tests.

* fix(cpp): stop #include from leaking class methods and namespace members (U1)

The C++ registry-primary resolver was emitting impossible CALLS edges
for ordinary headers: an including file's unqualified save() resolved
to User::save and unqualified foo() resolved to ns::foo. Two leak
paths converged on localDefs:

1. expandCppWildcardNames (file-local-linkage.ts) iterated the
   flattened localDefs and exported every simple tail, including
   class-owned methods and namespace-contained symbols. Replaced with
   a scope-aware filter: build nodeId -> owning Scope from
   Scope.ownedDefs and skip defs whose owning scope is Namespace or
   Class.

2. The shared global free-call fallback's pickUniqueGlobalCallable
   walks the workspace registry by simple name and would still hit
   class methods / namespace members even with wildcard expansion
   fixed. Plugged the gap via the existing isFileLocalDef hook —
   semantically 'logically invisible cross-file' — by tracking per-
   file non-globally-visible nodeIds (populateCppNonGloballyVisible,
   called from populateOwners) and adding an ownerId !== undefined
   fast-path for class-owned defs.

Side fix in shared finalize-algorithm.ts: when wildcard expansion
resolves to a real target but produces zero propagating names, the
edge was dropped, taking the file-level IMPORTS edge with it.
Preserve the original wildcard edge so #include dependencies survive
even when the header exposes no unqualified bindings.

Tests: cpp-include-no-class-leak, cpp-include-no-namespace-leak, and
cpp-anon-ns-same-file-visible fixtures. Negative tests mode-gated to
REGISTRY_PRIMARY_CPP=1 via the expected-failures registry — legacy
DAG has no scope-aware filtering on the global fallback; backporting
is out of scope. All 2104 resolver integration tests pass under
registry-primary mode.

* fix(cpp): suppress receiver-bound CALLS when integer-width overloads collide (U2)

C++ arity-metadata normalizes int, long, short, unsigned, size_t to
'int' so single-candidate flows like 'process(42L)' match a 'long'-
typed parameter via loose matching. But when both 'process(int)' and
'process(long)' coexist as method overloads, they both end up with
parameterTypes=['int'] in the registry, and pickOverload's narrowing
returns 2 candidates with no way to disambiguate. The previous code
picked candidates[0] arbitrarily, emitting a CALLS edge to the wrong
overload roughly half the time.

Fix:
- Add isOverloadAmbiguousAfterNormalization in overload-narrowing.ts
  that detects >1 candidate sharing identical parameterTypes sequences.
- Have pickOverload return a new OVERLOAD_AMBIGUOUS sentinel when this
  fires.
- In the receiver-bound-calls loop, when pickOverload signals ambiguity,
  suppress the edge AND add the site to handledSites so the late-stage
  emitReferencesViaLookup pass does not re-emit the pre-resolved
  reference. Without the handled-mark, the reference index still
  carries a toDef and emits the same wrong edge.

Graph schema has no ambiguous-target edge model, so emitting two
edges (one per candidate) would require a separate schema change.
Zero-edge is the only safe outcome.

Other languages: the ambiguity check is a precondition gate, not a
behavior change for normal narrowing. Languages whose normalizers do
not collapse distinct types into a single token (verified by grep
over *-arity-metadata.ts) will never produce >1 candidate with
identical parameterTypes from genuinely distinct declarations, so
the branch is effectively C++-only in practice.

Test: cpp-overload-int-long fixture asserts exactly .toBe(0) CALLS
edges. Count=1 = arbitrary pick (the bug); count>1 = unsupported
ambiguous-edge model. Mode-gated to REGISTRY_PRIMARY_CPP=1 — legacy
DAG has no OVERLOAD_AMBIGUOUS wiring; backporting is out of scope.

All 2105 resolver integration tests pass under registry-primary; all
139 cpp tests pass under both modes (3 negative tests skipped in
legacy as documented).

* test(cpp): add integration coverage for anonymous-namespace, using-namespace conflict, and std-shim leakage (U3+U4+U5)

Three new end-to-end fixtures exercise the resolver pipeline against
scenarios that previously had only unit-level coverage or no coverage
at all (Claude review Finding 7):

U3 — cpp-anon-ns-cross-file:
  helper.cpp declares 'namespace { void worker(); }' and calls it
  internally. caller.cpp declares a separate 'void worker()' and calls
  it. Asserts (a) the cross-file CALLS edge from caller's run() does
  not target helper.cpp's anonymous-namespace worker, and (b) the
  same-file edge from helper_entry() to its own worker still resolves
  (positive guard against a 'no edges at all' regression making the
  negative check vacuously pass). Includes a state-isolation guard
  that re-runs the same fixture and asserts identical results,
  proving clearFileLocalNames() is called by the pipeline entry.

U4 — cpp-using-namespace-conflict:
  Two headers each declaring 'namespace a { foo() }' and
  'namespace b { foo() }' respectively, plus a caller doing
  'using namespace a; using namespace b; foo()'. Asserts exactly
  zero CALLS edges. One edge = arbitrary pick (the bug); two edges
  would require an ambiguous-target edge model GitNexus does not
  have. Depends on U1 — without scope-aware filtering, both foo()s
  would already be in the importer's wildcard binding set as simple
  'foo', so the test would pass for the wrong reason.

U5 — cpp-using-namespace-std-smoke:
  Fixture-local 'namespace std { void cout_write(); void println(); }'
  shim rather than real <iostream> — captures the wildcard-leak
  shape deterministically without depending on system-header modeling
  stability (out of scope per plan). Asserts (a) the project-local
  call resolves correctly, (b) no leak to shim STL symbols, and (c)
  no CALLS/ACCESSES edges from the caller into std-shim.h at all.

Negative tests for U2/U4 mode-gated to REGISTRY_PRIMARY_CPP=1 via
the expected-failures registry; legacy DAG lacks the OVERLOAD_AMBIGUOUS
suppression and the namespace-aware filtering, so the leaks persist
there. All 2112 resolver integration tests pass under registry-primary;
all 146 cpp tests pass under both modes (4 negative tests skipped in
legacy as documented).

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix(cpp): scope-aware isSuperReceiver classification (U1)

The C++ isSuperReceiver hook used a regex `/^[A-Z]\w*::/` that
misclassified any uppercase-qualified call as a super-receiver call.
Singleton::getInstance(), std::Foo::bar(), and PascalCase namespace
calls all entered the super branch, where the absence of an enclosing
class (or wrong MRO context) dropped the resolution entirely.

Fix:
- New optional ScopeResolver hook isSuperReceiverInContext(text,
  callerScope, scopes). Languages where super classification depends
  on caller context define it; receiver-bound-calls.ts prefers it
  when defined and falls back to the simple isSuperReceiver(text)
  otherwise. Other migrated languages (Python, Java, C#, PHP, Go,
  TypeScript) are unchanged.
- C++ implementation: parse the LHS of '::' from the receiver text,
  resolve via findClassBindingInScope, and return true only when
  the LHS is a class-like def in the caller's enclosing class's MRO.
  Returns false for namespace LHS, unresolved LHS, self-class LHS
  (qualified self-calls aren't super), and any non-'::' form.
- Extended the C++ tree-sitter query to capture the LHS of
  qualified_identifier as @reference.receiver so qualified static
  member calls (Singleton::getInstance()) reach the receiver-bound
  Case 2 (class-name receiver) path. Without the receiver capture,
  qualified calls had no explicit receiver and could not resolve
  through any receiver-bound branch.

Test: cpp-namespace-qualified-not-super fixture. Singleton::getInstance()
from a free function asserts exactly 1 CALLS edge through the
qualified-call path. Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2113 resolver integration tests pass; all 147 cpp tests pass under
both modes.

* fix(cpp): suppress receiver-bound CALLS when default-arg overloads collide (U4)

ISO C++ rejects 's.f(1)' as ambiguous when both 'void f(int)' and
'void f(int, int = 0)' are declared on S. The previous resolver
returned the first viable candidate via pickOverload's fallback.

Extended isOverloadAmbiguousAfterNormalization to take an optional
argCount: when provided, the predicate compares only the first
argCount slots of each candidate's parameterTypes. Candidates whose
declared-prefix matches up to argCount are treated as ambiguous
because default arguments make all of them equally viable for the
call.

Without argCount, behavior is unchanged (the original int/long
normalization-collapse contract, full-length equality required).
pickOverload now passes site.arity so default-arg ambiguity fires.

Test: cpp-overload-default-arg-ambiguous fixture. s.f(1) where S has
f(int) and f(int, int = 0) asserts exactly .toBe(0) CALLS edges.
Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2114 resolver integration tests pass; all 148 cpp tests pass
under both modes.

* fix(cpp): two-phase template lookup suppresses dependent-base members (U3)

ISO C++ two-phase name lookup: inside a class template body, unqualified
calls MUST NOT bind to members of a dependent base class. Only this->name
or Base<T>::name forms make the lookup dependent. GCC and Clang both
reject the unqualified form with 'declaration of f must be available'.

Before this fix, GitNexus's global free-call fallback walked the
workspace registry by simple name and bound unqualified calls inside
template bodies to dependent-base members, producing CALLS edges the
compiler would reject.

Implementation:
- New languages/cpp/two-phase-lookup.ts module: per-pipeline state
  recording (className, dependentBaseName) pairs at capture time and
  resolving them to nodeId sets during populateOwners.
- captures.ts detectCppDependentBases walks the AST once finding every
  template_declaration containing a class/struct definition. For each,
  it collects template-parameter names (typename T, class T, non-type
  int N, template-template parameters) and walks each base in the
  base_class_clause checking whether any inner type_identifier matches
  a template parameter. Conservative bias: typename T::U, decltype,
  and template-template-parameter shapes also classified as dependent.
- Extended scope-resolution contract's isCallableVisibleFromCaller
  hook with optional callerScope and scopes fields. C++ implements
  the hook to consult isCppDependentBaseMember: when the candidate
  is a member of a dependent base of the caller's enclosing class,
  the hook returns false and pickUniqueGlobalCallable skips the
  candidate.
- clearFileLocalNames also clears the dependent-base state per
  pipeline run.

Fixtures:
- cpp-two-phase-dependent-base: Derived<T> deriving from Base<T>,
  unqualified f() and i inside Derived's body. Asserts zero CALLS
  edges and zero ACCESSES edges respectively.
- cpp-two-phase-this-qualified, cpp-two-phase-non-dependent-base,
  cpp-two-phase-namespace-free-call-inside-template: positive
  fixtures left as documented gaps (this-> and qualified-name
  resolution inside template bodies are pre-existing resolver
  weaknesses independent of U3). Tracked separately.

Negative test mode-gated to REGISTRY_PRIMARY_CPP=1 via the expected-
failures registry; legacy DAG has no two-phase lookup.

All 2116 resolver integration tests pass under registry-primary; all
150 cpp tests pass under both modes (5 negative tests skipped in legacy
as documented).

* fix(cpp): implement V1 ADL (Koenig lookup) for free-function calls (U2)

Plan 2026-05-13-001 U2. Adds argument-dependent lookup as a new
candidate-generating tier in `emitFreeCallFallback`: when ordinary
unqualified lookup is empty, ADL surfaces candidates from each
value-class-typed argument's enclosing namespace.

V1 boundary (locked by cpp-adl-pointer-arg-boundary fixture):
- only direct enclosing-namespace closure
- only directly-named class-type values (pointer / reference / template-
  spec args excluded; closure rules deferred to V2)
- ADL fires ONLY when ordinary lookup is empty (no union-and-resolve)

Parenthesized name `(f)(s)` suppresses ADL per ISO C++
[basic.lookup.argdep]/3.1. Multi-candidate ambiguity (e.g. `process(int)`
vs `process(long)` after C++ int-width normalization) returns the
ADL_AMBIGUOUS sentinel — caller suppresses entirely, mirroring the
OVERLOAD_AMBIGUOUS contract from plan 2026-05-12-002 U2.

Implementation:
- `cpp/adl.ts` — new module: per-pipeline argInfoBySite + noAdlSites Maps
  populated at capture time, classToNamespaceQualifiedName Map populated
  during populateOwners; `pickCppAdlCandidates` returns
  SymbolDefinition | ADL_AMBIGUOUS | undefined
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveAdlCandidates` hook
- `scope-resolution/passes/free-call-fallback.ts` — invokes ADL hook
  between `findCallableBindingInScope` and `pickUniqueGlobalCallable`;
  marks site handled on `'ambiguous'` so emit-references doesn't retry
- `cpp/captures.ts` — detects `parenthesized_expression` function wrap;
  per-arg classification (pointer/reference/value class) preserving the
  shape info the existing arity-narrowing normalizer strips
- `cpp/scope-resolver.ts` — registers hook, populates associated
  namespaces, clears state in loadResolutionConfig

Negative tests (parens, pointer-boundary, ambiguous) gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG has no V1/V2
ADL boundary or ADL_AMBIGUOUS suppression.

154/154 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
147 pass + 7 skipped under =0 (legacy parity baseline).

* fix(cpp): inline namespace transitive walking + qualified namespace resolution (U5)

Plan 2026-05-13-001 U5. Two ISO C++ inline-namespace semantics:

1. Unqualified-lookup transitive visibility: inline-namespace members
   reach the enclosing namespace's scope as if declared there. The
   `populateCppNonGloballyVisible` exemption keeps them globally visible
   so cross-file unqualified lookup finds them.

2. Qualified-receiver transitive visibility: `outer::foo()` resolves to
   `outer::v1::foo()` when `v1` is inline (and through arbitrarily-deep
   nesting like `outer::v1::experimental::foo`, matching libc++ `__1` /
   libstdc++ `__cxx11`).

The second behavior required a new resolver case in
`receiver-bound-calls.ts` (Case 1.5: language-specific qualified-receiver
member lookup) because C++ qualified-namespace member calls had no prior
resolution path — receiver-bound Case 1 only handled
`ParsedImport.kind === 'namespace'` (Python/JS-style) and Case 2 handles
class receivers, neither of which fired for `outer::foo()`. The new
hook `resolveQualifiedReceiverMember` is opt-in; languages without
C++-style qualified-name semantics omit it.

Implementation:
- `cpp/inline-namespaces.ts` — new module: per-pipeline
  `inlineNamespaceRangesByFile` + `inlineNamespaceScopeIds` Sets;
  `markCppInlineNamespaceRange` at capture time;
  `populateCppInlineNamespaceScopes` resolves ranges → scope IDs;
  `resolveCppQualifiedNamespaceMember` walks namespace scopes by simple
  name and descends transitively through inline children only.
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveQualifiedReceiverMember` hook to the contract.
- `scope-resolution/passes/receiver-bound-calls.ts` — Case 1.5 invokes
  the hook between Case 1 (namespace imports) and Case 2 (class-name
  receiver). Returns undefined for non-namespace receivers so Case 2
  still resolves class-qualified calls.
- `cpp/captures.ts` — detects `inline` keyword child on
  `namespace_definition`; records 1-based range to match Scope.range.
- `cpp/file-local-linkage.ts` — `populateCppNonGloballyVisible` exempts
  inline-namespace scopes so cross-file unqualified lookup keeps their
  members visible.
- `cpp/scope-resolver.ts` — wires `populateCppInlineNamespaceScopes`
  into populateOwners (BEFORE `populateCppNonGloballyVisible` so the
  exemption sees populated state); registers
  `resolveQualifiedReceiverMember` hook.

4 fixtures: `cpp-inline-namespace-unqualified`, `-versioned`,
`-nested` (two transitive inline hops, STL `__1` shape), and
`-adl-participation` (composes with U2 — ADL surfaces records declared
inside inline child namespaces). All 4 assert exactly 1 CALLS edge with
correct target file.

Versioned fixture gated under LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp
— legacy DAG can't disambiguate two same-name foos without inline
awareness. Other 3 coincidentally resolve in legacy.

158/158 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
150 pass + 8 skipped under =0 (legacy parity baseline).

* test(cpp): Phase 5 cross-unit composition tests for U1/U2/U3/U5

Plan 2026-05-13-001 Phase 5. Locks in correct behavior at the
intersections between the previously-shipped scope-resolver units.

Enhancement to U1: `isSuperReceiverInContext` strips template-argument
lists (`Base<T>` → `Base`) and namespace prefixes (`outer::v1::Base` →
`Base`) before resolving the receiver in the caller's scope chain. This
makes the super-receiver classification work for template-class
heritage shapes like `Base<T>::method()` and `outer::v1::Base<T>::f()`.

Three fixtures + four tests:

- `cpp-phase5-u1-u3-qualified-base-call`:
  `template<class T> struct Derived : Base<T>` with
  `Base<T>::method()` inside a template body. Asserts NO mis-routing
  (count = 0) — documents the V1 gap that template-class inheritance
  isn't captured as EXTENDS by the legacy DAG, so MRO walks are empty
  and the super branch can't dispatch. The composition still works
  correctly: U1's template-arg-stripping classifies `Base<T>` as a
  super candidate, but the empty-MRO terminates without false edges.

- `cpp-phase5-u2-u3-adl-from-derived`:
  `Derived : Base<T>` where `Base::record` shadows `audit::record`.
  Unqualified `record(e)` inside the template body should resolve via
  ADL to `audit::record` (because U3 + the `isFileLocalDef` class-
  owned filter suppress `Base::record`). Asserts 1 edge to audit.h
  and 0 edges to base.h.

- `cpp-phase5-u3-u5-inline-base`:
  `template<class T> struct Derived : outer::v1::Base<T>` where `v1`
  is inline. Unqualified `f()` inside `Derived<T>::g()` should NOT
  bind to Base::f (dependent-base suppression even across inline
  namespace prefix). Asserts count = 0.

Phase 5 tests asserting no-false-positives are gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG over-
resolves without the template-arg-stripping qualified-receiver path
and without two-phase dependent-base suppression.

162/162 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
152 pass + 10 skipped under =0 (legacy parity baseline).

feat: shared resilient-fetch (retries + circuit breaker) (#1448)
* feat: shared resilient-fetch (retries + circuit breaker)

Add a small, runtime-agnostic resilience layer in gitnexus-shared and
migrate every backend HTTP outbound call (CLI, MCP, wiki LLM, web → backend)
through it.

Helpers (gitnexus-shared/src/integrations/):

- retry.ts            — withRetry(fn, opts) with caller-supplied
                        retryability classification and full-jitter
                        exponential backoff.
- circuit-breaker.ts  — closed/open/half-open per-process breaker with
                        injectable clock, plus a keyed registry so
                        callers targeting the same endpoint share state.
- resilient-fetch.ts  — composed wrapper: retries 5xx + 429 + retryable
                        network throws, treats AbortSignal.timeout()
                        and 4xx (other than 429) as terminal, honors
                        Retry-After (capped at 30s), throws
                        CircuitOpenError when the breaker opens.

Migrations (no behaviour regression — all existing tests pass):

- gitnexus/src/core/embeddings/http-client.ts (covers analyze + MCP
  query path) — replaces inline linear-backoff retry.
- gitnexus/src/core/wiki/llm-client.ts — preserves Azure content-filter
  branch; resilientFetch handles 5xx/429.
- gitnexus-web/src/services/backend-client.ts (fetchWithTimeout helper)
  — small retry budget (2 attempts, 250–1500 ms) so a dead local
  backend still fails fast for the user.
- gitnexus-web/src/core/llm/settings-service.ts (OpenRouter model list).

Deliberately not migrated:

- gitnexus-web/src/services/backend-client.ts streamJob() — Server-Sent
  Events stream; the existing reconnect-with-Last-Event-ID logic is
  not unary-fetch shaped.
- gitnexus-web/src/components/SettingsPanel.tsx checkOllamaStatus() —
  one-shot health probe; retrying delays the "Ollama not running"
  error rather than improving UX.

41 new helper tests cover backoff math, breaker state transitions,
Retry-After parsing (delta-seconds + HTTP-date), 401/422 terminal
classification, and breaker fail-fast on three exhausted retry batches.

* fix(review): apply autofix feedback

Address Claude's two MEDIUM blocking findings on PR #1448 plus the
CodeQL SSRF false-positive flag.

- backend-client `fetchWithTimeout` now uses `AbortSignal.timeout()`
  merged with the caller's signal via `AbortSignal.any()`. Timer-fired
  aborts surface as `DOMException(name='TimeoutError')` so
  resilientFetch routes them through the terminal-network branch
  (no retry, no breaker hit), instead of incrementing the breaker
  for user-side network slowness.
- Method-aware retry budget in `fetchWithTimeout`: idempotent verbs
  (GET/HEAD/OPTIONS) keep the 2-attempt budget; POST/PATCH/PUT/DELETE
  default to single-attempt so a 5xx on `startAnalyze` cannot start
  a duplicate job. New `forceRetry` parameter for callers that
  know-idempotent mutations (e.g. DELETE of a known-deleted resource).
- `resilient-fetch.ts` carries a documented suppression for CodeQL
  js/server-side-request-forgery on the inner fetch call. Every
  concrete caller passes a hardcoded URL constant or a value from
  configuration (env vars, saved settings); user request input never
  flows into the URL parameter.
- New test file `backend-client-retry.test.ts` covers all three
  paths: GET retries on 503, POST does not retry, timeout does not
  increment the breaker.

* fix(resilient-fetch): address Codex adversarial findings

Closes the three blocking issues from Codex's review on PR #1448.

U1 — Add `recordNeutral()` to CircuitBreaker.
  Third outcome path that's an explicit no-op for state and the
  consecutive-failure counter. Distinct from `recordSuccess` (closes
  the breaker) and `recordFailure` (may open it). Used for outcomes
  that are neither evidence of backend health nor evidence of
  backend failure.

U2 — Route terminal-client / terminal-network through `recordNeutral`.
  Previously a 401 or local timeout called `recordSuccess`, which
  reset `consecutiveFailures` to 0. A 5xx → 401 → 5xx → 401 → 5xx
  sequence would NEVER trip the breaker because each 4xx in between
  erased the running count. Also classify external `AbortError` as
  terminal-network (was retryable-network), so caller-driven
  cancellation no longer retries against an already-aborted signal
  or counts toward breaker failures on exhaustion.

U3 — Per-origin breaker key in web `fetchWithTimeout`.
  Was hardcoded to `'web-backend'` even though `_backendUrl` is
  mutable via `setBackendUrl`. Switching backend URLs after a
  circuit tripped on host-A would strand the user during the full
  cooldown. Key is now `web-backend:<origin>`, so each backend URL
  gets its own breaker state.

Tests: +5 recordNeutral, +4 resilient-fetch (interleaved 4xx/5xx,
external AbortError, prior-state preservation), +1 web switch-backend
regression. All 70 gitnexus integration tests + 15 web tests green.

* fix(resilient-fetch): tolerate header-less fetch mocks on 429

`classifyOutcome` called `resp.headers.get('Retry-After')` directly,
which crashed when a test stubs `fetch` with a plain object like
`{ ok: false, status: 429 }` (no `headers` field). Real `Response`
always has Headers, so this surfaces only in test setups, but the
helper has no business assuming caller-side correctness on this — the
defensive guard is cheap and a missing `Retry-After` falls through to
exponential-backoff retry like any 429 without the header.

Surfaced by `gitnexus/test/unit/http-embedder.test.ts > retries on
rate limit`, which the embeddings migration exercises against a
plain-object 429 stub. Locked in with a new
`classifies 429 from a header-less fetch mock without throwing` case.

* fix(review): apply autofix feedback

Closes findings from the third multi-agent review pass on PR #1448.

#1 (P1) callLLM had no per-attempt timeout
  Wiki LLM calls passed no `signal` to resilientFetch; each of three
  retry attempts could hang indefinitely on a frozen TCP connection.
  Add `signal: AbortSignal.timeout(60_000)` so the per-attempt budget
  matches what http-client.ts and backend-client.ts already provide.

#2 (P2) drop dead `lastRetryableResp` post-loop fallback
  Variable was set in one switch arm but only read in unreachable code
  after the loop. The retry loop always returns/throws on every
  iteration. Keep only the defensive `throw` so TypeScript's
  control-flow analysis still sees `Promise<Response>` as the return.

#5 (P2) gate test-only exports behind a subpath
  `__resetBreakerRegistry__` and `classifyOutcome` were reachable from
  the main `gitnexus-shared` barrel — production code calling
  `__resetBreakerRegistry__` from a tool implementation would silently
  nuke every circuit breaker process-wide. Move to a new
  `gitnexus-shared/test-helpers` subpath export. Production callers
  see the cleaner public API; tests import via the explicit
  `gitnexus-shared/test-helpers` path.

#6 (P2) exhaustiveness guard on Outcome switch
  Add a `default: const _: never = outcome` arm so a future sixth
  `Outcome.kind` won't compile silently — it'll surface at the switch
  site rather than fall through to a retry/no-retry default.

#9 (P3) document cumulative wall-clock budget
  Add a "Cumulative wall-clock budget" paragraph to resilientFetch's
  JSDoc explaining the worst-case total wait (`maxAttempts × (per-attempt
  timeout + capDelayMs)` ≈ 60s with defaults) and pointing callers at
  outer `AbortSignal.timeout()` when they want a tighter bound.

Deferred to follow-up PRs (per review's Auto-resolve recommendation):
  - #3 idempotency knob to shared API (forceRetry into ResilientFetchOptions)
  - #4 publish.ts migration to resilientFetch
  - #7 parseRetryAfter past-HTTP-date / negative-seconds asymmetry
  - #8 recordNeutral counter time-decay (documented breaker semantic)

* fix(circuit-breaker): gate half-open to a single in-flight probe

Closes the Codex adversarial-review finding on PR #1448 that flagged a
recovery-time thundering herd: when cooldown expired, every concurrent
caller transitioned the breaker to half-open and probed the still-
recovering dependency in lockstep, defeating the breaker's "fail fast"
promise.

U1 — probe-permit gate in CircuitBreaker.check()
  Added a `probeInFlight: boolean` field. After cooldown expires, the
  first `check()` admits the probe and consumes the permit; subsequent
  callers throw `CircuitOpenError` with a configurable
  `halfOpenRetryAfterMs` (default 1000ms) until the probe resolves.

  Critical design point: `recordNeutral` now RELEASES the permit but
  does NOT transition state. Without that split, a single `TimeoutError`
  from per-attempt `AbortSignal.timeout` (which routes through neutral
  classification) would permanently park the breaker in half-open. By
  separating permit-release from state-resolution, we keep the
  "neutral doesn't claim health" semantic without creating that wedge.

  Other changes:
  - `halfOpenRetryAfterMs` is now a constructor option for consumers
    with long-running protected ops (LLM streaming, large uploads).
  - `getState()` is documented as a pure read; the implicit
    Open -> Half-Open transition lives in `check()` only, so tests
    that inspect state never inadvertently consume a probe permit.
  - `isProbeInFlight()` test-only accessor for assertion clarity.
  - JSDoc on `check()` records the JS event-loop atomicity dependency
    and the load-bearing `try/finally` pairing invariant.

U2 — End-to-end concurrency regression through resilientFetch
  Three new scenarios in resilient-fetch.test.ts (26 -> 29):
  - 3 concurrent calls + probe gets 200 -> 1 hits fetch, 2 throw
    CircuitOpenError, breaker closes.
  - 3 concurrent calls + probe gets 503 -> ResilientFetchExhaustedError
    on probe; concurrent callers see halfOpenRetryAfterMs (1000ms);
    fresh caller after probe resolves sees the FULL new cooldown
    (10000ms), not the probe-in-flight default.
  - Probe cancelled mid-flight via AbortError -> permit released,
    state stays half-open, next caller becomes the new probe and
    succeeds.

Plus 9 new circuit-breaker unit tests (16 -> 25) covering the permit
gate, recordNeutral-releases-permit semantic, fresh-cooldown distinction,
default vs configurable halfOpenRetryAfterMs, getState() purity, and
the three-probes-via-neutrals chain.

Total integration test count: 70 -> 82. All 106 gitnexus + 15 web
tests pass; both packages typecheck.

Maintainer decisions (deferred per plan 003 Open Questions):
  - Plan 002's deferral judgement was reversed on Codex's argument
    without new measurement / incident data. The reversal is defensible
    on principle (Hystrix / Resilience4j alignment) but lacks workload-
    driven evidence.
  - Probe-blocked callers throw silently (no log / event hook). R4's
    "no new public API" prevents adding observability; loosen if a
    debug log on probe-blocked is wanted.

* refactor(embeddings): replace bespoke HF breaker with shared CircuitBreaker

Deleted the local `HfDownloadCircuitBreaker` class and the manual
retry loop in `withHfDownloadRetry`. Both are now backed by the
shared `gitnexus-shared` primitives:

- `hfDownloadCircuit` is `new CircuitBreaker({ failureThreshold,
  cooldownMs, key: 'hf-download' })` — same state machine as before
  PLUS the single-permit half-open gate that prevents recovery-time
  stampedes when CLI + MCP embedders concurrently re-load the model.
- `withHfDownloadRetry` delegates the loop to `withRetry` from the
  shared package. Per-attempt timeout (`withDownloadTimeout`),
  network-vs-non-network classification, circuit recording, and the
  `onRetry` callback wire through `withRetry`'s `isRetryable`
  callback.

Behaviour preserved:
- Pre-flight `CIRCUIT_OPEN_TAG` rejection when the breaker is open.
- Mid-loop `CIRCUIT_OPEN_TAG` "opened after N consecutive failures"
  when a network error trips the threshold.
- Non-network errors (e.g. CUDA unavailable) bypass retry and go
  through `recordNeutral` instead of resetting the breaker's
  failure-count progress.
- `onRetry(attempt+1, max, err)` fires only when there's a next
  attempt, matching the prior semantic.

Generic CircuitBreaker gained two inspection accessors:
- `getOpenedAt(): number | null`
- `getCooldownMs(): number`
Used by `withHfDownloadRetry` to compute `secsUntilReset` without
consuming a probe permit (which `check()` would do).

Test consolidation: the 7 bespoke `HfDownloadCircuitBreaker`
state-machine tests in hf-env.test.ts were 1:1 duplicates of
existing tests in `circuit-breaker.test.ts` and were deleted.
Remaining 42 hf-env tests all pass; full integration sweep (148
gitnexus + 15 web) green.

feat(cli): add gitnexus publish for opt-in understand-quickly registry (#1425)
* feat(cli): add `gitnexus publish` for opt-in understand-quickly registry

Adds a small, opt-in command that fires a single `repository_dispatch`
event at `looptech-ai/understand-quickly` to ask the registry for an
instant resync of the current repo's entry. No graph file is uploaded;
the registry pulls from raw.githubusercontent.com per the protocol at
https://github.com/looptech-ai/understand-quickly/blob/main/docs/integrations/protocol.md.

  - Pure helpers (id parsing, payload construction, validation) live in
    `gitnexus-shared/src/integrations/understand-quickly.ts` so the
    package stays Node-free and the same logic is testable in isolation.
  - The CLI command lives in `gitnexus/src/cli/publish.ts`. Without
    `UNDERSTAND_QUICKLY_TOKEN` it is a no-op (exits 0 with one
    informational line); with the token it POSTs the dispatch and
    surfaces 204 / 401 / 404 / 5xx distinctly.
  - The id defaults to `<owner>/<repo>` parsed from the `origin` remote
    and can be overridden with `--id`.
  - Refuses to publish when no `.gitnexus/` index exists, with a
    `gitnexus analyze` hint.

Tests: a new vitest unit covers the pure helpers (8 + 8 + 2 cases) and
the no-token no-op path with a `fetch` spy that fails the test if the
network is touched. README gets a one-paragraph "Publishing to
understand-quickly" section near the existing CLI docs.

* fix(uq-publish): address review blockers + high-severity items

Addresses CodeQL polynomial-regex (HIGH), token-gate ordering, distinct
401/403/404/422 response branches, fetch timeout, expanded test coverage,
tightened owner/repo validation, and non-GitHub remote rejection.

See response thread on PR #1425 for the per-finding rationale.

* fix(publish): address Claude review on PR #1425

- AbortError → TimeoutError: AbortSignal.timeout() throws a
  DOMException with name 'TimeoutError', not Error{name:'AbortError'}.
  Match the pattern used in core/embeddings/http-client.ts so the
  user-facing "timed out after 15000ms" message actually fires. Update
  the regression test to throw a real DOMException — the previous fake
  was a false-green.
- isValidOwnerRepo: forbid trailing hyphen in the owner segment.
  GitHub rejects this at account-creation time; allowing it here meant
  hand-typed --id values like 'my-org-/repo' would pass our regex and
  422 from GitHub.
- Add publish-command coverage to cli-index-help.test.ts (asserts on
  --id, --skip-git, the registry name, and the token env var) and
  cli-commands.test.ts (asserts publishCommand is exported as a
  function). Catches accidental command-registration deletion.

851d2ab749 fix(typescript): address review findings — formatting + tighter test assertions
Addresses the automated review findings on PR #1175:

- prettier --write the 3 files flagged by `quality / format` CI check
  (query.ts, typescript-hof-callbacks.test.ts, typescript-jsx-as-call.test.ts).

- [medium] typescript-jsx-as-call.test.ts: tighten the combined HOF+JSX
  assertion from `toBeGreaterThan(0)` to `toHaveLength(1)`. A single
  `<Foo />` is one logical invocation; the bounds-only assertion would
  have masked a duplicate-CALLS-edge regression (e.g. if both
  `jsx_self_closing_element` and a generic call pattern matched the
  same site).

- [medium] typescript-hof-callbacks.test.ts: replace the vacuously-true
  `for (c of calls) expect(...)` Zustand assertion with a structural
  one. Old form passed unconditionally when `calls` was empty (any
  change that silenced ALL CALLS edges from store.ts would have
  slipped through). New form asserts both: (a) at least one File-rooted
  edge exists (proving the `isCallerAnchorLabel` fallback fires), and
  (b) no edge sources from anything else (proving the fallback fires
  exclusively).

- [low] finalize-algorithm.ts (`findExportByName`): rephrase the
  comment to make the language-agnostic nature of the tie-break rule
  explicit. The implementation was already correct for all migrated
  languages; only the comment overplayed the TypeScript specificity.

- [low] captures.ts (arity synthesis): add a comment explaining why
  JSX call anchors (`jsx_self_closing_element` / `jsx_opening_element`)
  intentionally don't synthesize `@reference.arity`. Name-only
  resolution is correct for React (components aren't overloaded in the
  current graph model); a JSX-aware synthesizer counting jsx_attribute
  children would be needed if that ever changes.

No production behavior change. All 8/8 HOF + 7/7 JSX + 236/236
typescript + 11/11 api-deep-flow integration tests still pass.
gitnexus and gitnexus-shared typechecks clean.

7be595d317 fix(typescript): capture missed CALLS edges from HOF callbacks and JSX
Two distinct gaps in the TypeScript scope-resolution path were silently
dropping call edges in real-world React + TanStack + Zustand codebases.
On the bug reporter's repo (Sourcerer-fe, 1185 src/ functions), 504
missing Function->Function CALLS edges are now captured (+61.6%) and
the no-outgoing-CALLS orphan rate drops from 73.2% to 60.3%.

HOF / arrow-callback caller-attribution (3 cooperating fixes):
  - typescript/query.ts: @declaration.function anchor moved from the
    wrapping lexical_declaration to the inner arrow_function /
    function_expression, so anchor.range aligns with @scope.function and
    pass2AttachDeclarations lands the def on the arrow's own scope.
  - finalize-algorithm.ts: findExportByName prefers callable / class-
    like defs over Variable when localDefs contains both for the same
    name (TS emits two defs per `const fn = () => {}`).
  - graph-bridge/ids.ts: resolveCallerGraphId's walk-up class-fallback
    now uses isCallerAnchorLabel restricted to Function / Method /
    Constructor / Class / Interface / Struct / Enum, so module-level
    calls fall through to the File node instead of mis-attributing to
    sibling Variable defs (the Zustand `create()(devtools(...))`
    phantom-self-loop regression).

JSX as a CALLS edge (2 cooperating fixes):
  - typescript/query.ts: new TSX_JSX_QUERY_SUFFIX (TSX-grammar only)
    captures jsx_self_closing_element / jsx_opening_element as
    @reference.call.free / @reference.call.member. PascalCase predicate
    filters native HTML elements (<div>, <span>) so they don't emit
    edges to nonexistent targets.
  - typescript/captures.ts: shouldEmitReadMember extended with
    jsx_self_closing_element / jsx_opening_element parent cases to
    suppress phantom ACCESSES edges on member-form JSX names.

Tests: 8 HOF assertions + 7 JSX assertions across two new integration
test files plus 13 minimal fixtures. typescript.test.ts (236),
api-deep-flow.test.ts (11), and scope-resolution / scope-extractor unit
tests (613) pass with no regressions.
