fix(zig): vendor tree-sitter-zig so npm i -g no longer warns on peers (#3180)
* fix(zig): vendor tree-sitter-zig so npm i -g no longer warns on peers

Published overrides do not apply to dependents, so the Zig optionalDependency
kept warning that tree-sitter@0.21.1 does not satisfy peerOptional ^0.22.1.
Load it from vendor/ like Dart/Kotlin/Swift instead.

* fix(ci): add zig parse snippet to prebuild validate

The six zig prebuild jobs failed at "Validate the .node loads and parses"
because snippets[GRAMMAR] was undefined and tree-sitter threw
"Input must be a function".

Check for the vendored package without loading its native binding so a
broken installed Zig grammar fails the parsing test instead of skipping.
Match the optional child descriptor in the Zig metadata declaration and
include Zig in the two optional/vendored grammar comments.

Validation: 159 targeted tests, TypeScript, metadata type fixture, and
formatting passed. Injected native-load failure now fails instead of
skipping; explicit Zig opt-out still skips.

feat: add Zig language support (#1432)
* feat: add Zig language support

Adds a Zig LanguageProvider grounded in @tree-sitter-grammars/tree-sitter-zig 1.1.2.
The grammar's published peerOptional `tree-sitter@^0.22.1` is suppressed via an
npm `overrides` entry that aliases the peer to the bundled `tree-sitter@0.21.x`;
load-time smoke testing confirmed ABI compatibility.

v1 capabilities:
  - .zig file detection + Prism syntax mapping
  - Top-level + nested function_declaration as Function/Method
  - struct/enum/union (anonymous in the grammar — owner name resolved from the
    enclosing variable_declaration in class/field/method extractors)
  - container_field as struct/union fields and enum variants
  - top-level const/var as Variable nodes
  - free + member call_expression as @call edges
  - @import("./foo.zig") local-file resolution; std and external packages
    return empty (no ghost edges)
  - pub keyword detection for export checking
  - no heritage hooks (Zig has no inheritance; queries never emit @heritage.*)

Generic extractor changes (backward-compatible):
  - field-extractors/generic.ts and method-extractors/generic.ts: empty
    `bodyNodeTypes` falls back to the type declaration node itself as its own
    body container — needed because Zig's struct_declaration directly contains
    its container_field children. (The `extractOwnerName` hook this commit
    originally introduced now exists upstream; Zig just configures it.)

Out of scope (deferred):
  - usingnamespace, build.zig.zon package graph, comptime/anytype
  - scope-resolution hooks (emitScopeCaptures, interpretImport, …): Zig is
    classified `experimental` and uses the generic fallback resolution path
  - cross-package imports (std, deps)

Tests:
  - new fixture test/fixtures/sample-code/simple.zig
  - Zig describe block in tree-sitter-languages integration test
  - simple.zig added to parsing.test.ts fixture-existence list
  - Zig added to ingestion-utils detection unit test
  - Zig smoke case in parser-loader-abi.test.ts
  - Zig grammar registered in the grammar-literal validation gate

* feat(zig): integrate build.zig.zon resolution + Union label from PR 1096

Ports the additive pieces of grgisme's standalone Zig provider PR
(https://github.com/abhigyanpatwari/GitNexus/pull/1096) onto the rebased
provider:

  - build.zig.zon `.path` dependency resolution for bare-name
    @import("pkg") (parseZigBuildZon / loadZigBuildZon in
    language-config.ts, resolveZigImportInternal in import-resolvers/zig.ts,
    wired through ImportConfigs.zigBuildZon). `.url` deps and
    repo-escaping paths return null cleanly. 13 unit tests.
  - `union(enum)` containers now produce `Union` nodes (not Struct):
    'Union' added to ClassLikeNodeLabel + CLASS_LIKE_LABELS, the Zig query
    tags @definition.union, CONTAINER_TYPE_TO_LABEL maps union_declaration
    to 'Union'. The label was already plumbed graph-wide on main.
  - /^build$/ entry-point pattern (build.zig).
  - zig-basic lang-resolution fixture + resolvers integration test.

Adapted to current main while porting:

  - labelOverride relabels container-nested fns Function → Method
    (mirrors isKotlinClassMethod); the structure phase no longer derives
    Method from the legacy method-extraction path for plain
    @definition.function captures.
  - IMPORTS/CALLS edges require scope-resolution hooks
    (emitScopeCaptures / interpretImport) since the legacy DAG removal;
    Zig does not implement them yet, so the integration test documents
    that with a skipped import-edge case. The resolver itself is wired
    into the resolver factory and becomes live when the hooks land.

Not ported: named-bindings extractor (the legacy namedBindingExtractor
API no longer exists) and the bespoke field extractor (the generic
factory's extractOwnerName / empty-bodyNodeTypes hooks cover Zig).

* feat(zig): scope-resolution hooks — IMPORTS and CALLS edges (Ring 3)

Implements the registry-primary scope-resolution path for Zig, the
prerequisite for cross-file edges since the legacy DAG removal. Adds the
standard per-language stack under languages/zig/:

  - query.ts: scope query (containers as Class scopes, blocks, functions),
    declarations (container anchors placed on the container node itself so
    the def lands in its own Class scope and the name binding auto-hoists
    to the parent — populateClassOwnedMembers needs the class-like def
    among the class scope's ownedDefs), @import statements (#eq?-gated
    builtin), parameter/constructor type bindings, and call/constructor
    reference sites. The grammar is required lazily (optionalDependency).
  - captures.ts: emitZigScopeCaptures — groups query matches, drops the
    plain-variable group for container/import bindings (their dedicated
    rules bind the name), and relabels container-nested fns
    @declaration.function → @declaration.method (labelOverride parity).
  - interpret.ts: namespace-kind imports (const x = @import("…")) and
    type bindings — self-parameter convention marks the receiver, Zig
    sigils (*, ?, [], error unions, const) stripped from type names while
    dotted qualifiers (mod.T) are preserved for Case-3 namespace-prefix
    receiver dispatch.
  - simple-hooks.ts: parameter bindings stay function-local (Go
    rationale), local-over-import merge precedence, bounds-check arity
    (always 'unknown' today — no synthesized arity metadata).
  - scope-resolver.ts: emit-side wiring; build.zig.zon threads through
    loadResolutionConfig into the same resolveZigImportInternal the legacy
    resolver config wraps. fieldFallbackOnMethodLookup off (statically
    typed). Registered in SCOPE_RESOLVERS.

The resolvers integration test un-skips the import-edge case and gains
CALLS assertions: free call (main → helper) and receiver-bound method
dispatch through a namespace-qualified constructor
(var p = pioneer.Pioneer{…}; p.tick() → main → tick).

* fix(zig): Union is class-like + missing-grammar warning (review pass)

Self-review findings on the Zig branch:

  - scope/walkers.ts `isClassLike` and finalize-algorithm's
    CALLABLE_OR_TYPE_LIKE did not include 'Union': a `union(enum)`
    container's methods got no ownerId from populateClassOwnedMembers, so
    method dispatch on union receivers silently dropped. Widened both
    sets; the zig-basic fixture gains a Tag method + a CALLS assertion
    (main → isEnergy) that fails without the widening (verified by
    reverting).
  - optional-grammars.ts now lists tree-sitter-zig with an npm `probe`
    (it is an optionalDependency, not vendored): users with .zig files
    and no prebuild get the standard one-line stderr warning instead of
    a silently degraded index.
  - Deduplicated the container-method predicate: `isZigContainerMethod`
    + ZIG_CONTAINER_TYPES now live once in languages/zig/captures.ts and
    feed both the provider labelOverride and the scope-capture relabel.
  - README language matrices: Zig row now claims Type Annotations,
    Constructor Inference, and Config (build.zig.zon) — all true since
    the scope-resolution hooks landed.

* fix(zig): anchor @declaration.variable to the binding identifier

`(variable_declaration (identifier) @declaration.name)` matched EVERY
identifier child of the node, so `const first = target;` also declared a
phantom local named `target` in the enclosing block. That phantom shadowed
the real function for later references (and starved callable-value-flow
seeds of a target). The `.` anchor pins the pattern to the first named
child — the bound name.

Regression test in resolvers/zig.test.ts pins the capture set.

* feat(zig): callable-value-flow captures + main's per-language conformance gates

Post-rebase catch-up: since this branch forked, main added three "every
registered language must appear here" tests. Each needs a Zig entry:

- callable-value-flow (#2522): Zig now emits `@callable-flow.*` facts via
  `synthesizeCallableFlowCaptures` (ZIG_CALLABLE_CAPTURE_OPTIONS in
  zig/captures.ts). tree-sitter-zig's `call_expression` carries arguments
  as direct children with no wrapper node, which the shared helper could
  not decompose, so this adds a language-neutral `extractCallArguments`
  hook (mirror of `extractFunctionParameters`; `undefined` = shared path).
  Zig joins the provider matrix as 'matrix' with a real assign→copy→
  argument→invoke case.
- external-import-conformance (#2953): `@import("std")` beside a decoy
  `src/std.zig` resolves to nothing; the decoy stays reachable via the
  relative spelling. Zig holds the property (no suffix fallback), so it is
  a case, not a KNOWN_GAPS entry.
- import-target-index-reuse contract (#2909): membership-probe-only
  fixture (minimumScans: 0, same shape as Rust).

* fix(zig): address gitnexus-check review findings

One commit per the bot's list so each item is easy to check off:

- parser-loader: Zig row gains `userSkippable: true`, so
  `GITNEXUS_SKIP_OPTIONAL_GRAMMARS` (=1 or a list naming `zig`) disables it
  at analyze time like swift/dart/kotlin — as `optional-grammars.ts` already
  documented. Covered in parser-loader-skip-optional.test.ts.
- export-detection: `zigExportChecker` stops at the first declaration it
  reaches. A non-`pub` fn inside `pub const T = struct {…}` was reported
  exported because the walk continued up to the wrapper.
- import-resolvers/zig: a `.path = "."` dep normalizes to '' and no longer
  grows a leading slash (`/src/main.zig` could never match).
- language-config: build.zig.zon parsing strips `//` comments string-aware
  (a `//` inside `.url = "https://…"` survives) and matches braces while
  skipping string literals, so a commented-out `.path` cannot declare a dep
  and a `}` in a comment/string cannot truncate the block.
- method-extractors/configs/zig: the leading `self` receiver is excluded
  from `parameters` (Rust parity). Fixing that exposed a worse bug: the
  `parameters` node is a plain child of `function_declaration`, not a
  `parameters:` field, so `childForFieldName('parameters')` was always null
  and every Zig method had no parameters, no receiver and `isStatic: true`.
  One `zigParameterList` helper now feeds all three readers.
- variable-extractors/configs/zig: container (`struct`/`enum`/`union`) and
  `@import` bindings are skipped via the same predicate the scope captures
  use (`isZigContainerOrImportBinding`), instead of the comment merely
  claiming they were.
- tree-sitter-languages.test.ts: the "missing grammar" case now forces the
  absent-binding path through the loader's runtime opt-out on a fresh module
  instead of passing vacuously when the package is installed.

New: test/unit/zig-extractors.test.ts (exports, receiver/parameters,
variable guard); zig-import-resolver.test.ts gains the `.` dep, comment and
brace cases.

The `createFieldExtractor` heads-up needs no change: the added branch is
unreachable for every existing config (none has empty `bodyNodeTypes`).

* fix(zig): address second gitnexus-check review pass

- import-resolvers/zig: `..` above the repository root now returns null
  instead of aliasing a same-named root file (`../bar.zig` from `main.zig`
  is not `bar.zig`); the stale "extension is stripped and re-added" comment
  is corrected to what the code does.
- variable-extractors/configs/zig `extractType`: read the `type:` field only.
  The positional fallback returned the INITIALIZER of `const f = target;`
  as its type and gave up on compound annotations (`*Foo`, `?[]const u8`).
  The comment claiming 1.1.2 has no `type` field on variable_declaration
  was wrong (verified by AST dump) — and it is what led the review to
  suspect the callable-flow `extractAssignment` callback, which was
  already correct for `extern var f: T;`.
- receiver detection: only a FIRST parameter named `self` is the receiver.
  `emitZigScopeCaptures` tags first-position parameters
  (`@type-binding.first-parameter`), `interpretZigTypeBinding` requires the
  tag as well as the name, so `zigReceiverBinding` no longer turns
  `fn f(a: u32, self: T)` into an instance method.
- resolvers/zig.test.ts: both suites `describe.skipIf(!zigAvailable)`
  (Swift/Dart pattern) — the grammar is an optionalDependency.
- tree-sitter-languages.test.ts: the Zig parsing case gates on
  `isLanguageAvailable` instead of a catch-all `return`, so an installed
  grammar that fails to load fails the test; comment no longer calls Dart
  and Swift npm optionalDependencies (they are vendored).
- test/helpers/literal-collectors: `DIR_LANG` gains `zig`, so literals under
  `languages/zig/**` are validated against the Zig grammar alone rather than
  against every grammar.
- walkers.ts `isShapeLike` doc: Union IS included (via isClassLike, wired by
  Zig's union member container); Typedef remains the only deferred one.
- language-config `ZigBuildZonConfig.pathDeps` doc: values are the raw
  `.path` strings; the resolver normalizes.

Tests: zig-import-resolver (+1), zig-extractors (+3).

* fix(zig): address third gitnexus-check review pass

- language-config `parseZigBuildZon`: the `.dependencies = .{` header and
  the per-entry `.<name> = .{` headers are matched only OUTSIDE string
  literals (per-offset string mask + `matchZonHeader`). A `.name` or
  `.description` value spelling `.dependencies = .{ .fake = .{ .path = … } }`
  used to be taken as the block and returned the fake dep instead of the
  real top-level one.
- import-resolvers/zig: an absolute import (`@import("/foo.zig")`) returns
  null. The path walker skipped every empty component, so the leading `/`
  vanished and `/foo.zig` resolved as importer-relative `src/foo.zig` — an
  in-repo edge for an import Zig rejects as outside the module path.
- tree-sitter-languages.test.ts: the Zig parsing case gates on the PACKAGE
  being installed (`createRequire().resolve`, minus a deliberate
  `GITNEXUS_SKIP_OPTIONAL_GRAMMARS` opt-out), not on `isLanguageAvailable`,
  which is false for absent AND for installed-but-broken bindings — so a
  load failure (ABI mismatch, bad export) now fails the test instead of
  skipping it, as the comment already claimed.
- walkers.ts `isShapeLike` doc: `Union` sits in `isClassLike` because that
  is the label set the ownership walkers consult, not because unions
  inherit — Zig has no inheritance and no heritage hooks. The previous
  wording ("inheritance-capable owner") said otherwise.
- Not re-fixed (already addressed in the second pass, findings carried
  over): "receiver = any parameter named self" — `interpretZigTypeBinding`
  only sources a first-position parameter as `self`; `zigReceiverBinding`'s
  doc now states that invariant. "`DIR_LANG` has no zig entry" — it does.
  Extended one level out: `BASENAME_LANGS` (`zig.ts`) and `PREFIX_LANGS`
  (`ZIG_`) map to the Zig grammar too, so extractor configs and the
  export-detection set are validated against Zig alone. That immediately
  caught a dead `childForFieldName('parameters')` in
  method-extractors/configs/zig `zigParameterList` (there is no such field;
  the named-child lookup was already the one doing the work) — removed.

Tests: zig-import-resolver (+2: absolute path, header inside a string);
both fail on the previous code.

* fix(zig): address fourth gitnexus-check review pass

- language-config: `parseZigBuildZon` only accepts a `.path` that is a
  DIRECT field of a dependency entry. Nested blocks inside the entry body
  are blanked (string-aware, offsets preserved) before the `.path` regex
  runs, and a match starting inside a string literal is rejected, so
  `.dep = .{ .url = "…", .meta = .{ .path = "x" } }` no longer becomes a
  path dep. Regression test in zig-import-resolver.test.ts (fails on the
  previous code).
- tree-sitter-languages test: the "grammar is absent" case now drives the
  loader's real `source.load()` catch branch — `node:module` is stood in
  with a `createRequire` whose require throws MODULE_NOT_FOUND for
  `@tree-sitter-grammars/tree-sitter-zig` and delegates everything else —
  instead of the `GITNEXUS_SKIP_OPTIONAL_GRAMMARS` opt-out, which has its
  own test. It also asserts the opt-out flag is NOT set and that other
  grammars still load (non-fatal optional failure).

Not re-fixed:
- "Return type is read from the wrong tree-sitter field": tree-sitter-zig
  1.1.2 has NO `return_type` field on function_declaration — the type after
  `)` is the `type` field (AST dump: `builtin_type "i32" field=type`; the
  proposed `childForFieldName('return_type')` is null for every function).
  A pin test in zig-extractors.test.ts asserts both the grammar fact and
  that `returnType` is extracted (`void`, `!*Counter`).
- "`DIR_LANG` has no zig entry": it does (added in the first pass and
  answered again in the third); the finding is carried over unchanged.

* fix(zig): address fifth gitnexus-check review pass

- tree-sitter-languages test: the Zig "functions, structs, enums, and
  imports" case now asserts the `import.source` capture for
  `const std = @import("std");` (the fixture's only import), so a query
  change that drops Zig import matching fails it instead of passing
  unchanged.

Not re-fixed:
- "Return type is read from the wrong tree-sitter field": carried over from
  the fourth pass unchanged. tree-sitter-zig 1.1.2 has no `return_type`
  field on function_declaration; the return type IS the `type` field, and
  the pin test added in the fourth-pass commit
  (zig-extractors.test.ts, `childForFieldName('return_type')` is null,
  `returnType` = `void` / `!*Counter`) proves it.
- "`DIR_LANG` has no zig entry": carried over unchanged for the third time;
  the entry exists since the second-pass commit.

* feat(zig): export fn visibility, opaque containers, named test blocks, member ownership

Ports the parts of upstream PR #305 (closed, unmerged) that our Zig
provider lacked, plus two gaps found while porting.

- `export fn` / `export var` (C-ABI linkage, never `pub`) are exported;
  the pub/export predicate is now shared by the export checker and the
  method/variable extractors' visibility (`hasZigVisibilityKeyword`).
- `const H = opaque { … }` is a Struct-labelled container (it may own
  methods, never fields) in both the structure queries and the scope
  query; ZIG_CONTAINER_TYPES is the single source for the extractor
  configs.
- `test "name" { … }` blocks are Function nodes named by the string
  node WITH quotes, so `test "add"` beside `fn add` cannot merge onto
  Function:<file>:add; `test_declaration` joins FUNCTION_NODE_TYPES and
  the Zig method config names it in the enclosing-function walk, so
  calls inside a test attribute to the test. Anonymous `test {}` and
  decl-tests `test add {}` are scopes without a node (an empty-name hook
  result stops the walk instead of falling through to the identifier of
  the function under test).
- Empty container bodies (`struct {}`, `opaque {}`) no longer mint a
  nameless Property: tree-sitter-zig 1.1.2 recovers them as a
  container_field with a MISSING identifier; #not-eq? guards in both
  queries and the field extractor drop it.
- Owner walk (`findEnclosingClassInfo`): an anonymous container bound
  by the enclosing `variable_declaration` takes the binding identifier,
  same shape as the Go `type_spec` branch. Before this NO Zig member
  had an owner — zero HAS_METHOD / HAS_PROPERTY edges for Zig.

Not ported from #305, deliberately: `builtInNames` (a bare-name call-site
drop filter; `alloc`/`free`/`append`/`print` are the most common user
method names in Zig and `std.*` receivers are already external via the
import binding), `usingnamespace` (removed in Zig 0.15), `@cImport`,
`build.zig` ignore, and the web-app changes.

* test(zig): absent-grammar case owns GITNEXUS_SKIP_OPTIONAL_GRAMMARS

The loader parses the opt-out variable lazily once per module copy, so
under `GITNEXUS_SKIP_OPTIONAL_GRAMMARS=zig` (or `all`) — a supported way
to run — the fresh loader took the opt-out branch and the "not the
opt-out path" assertion failed before the absent-binding path ran.

Clear the variable for the fresh module and restore it in `finally`,
instead of returning early: the branch stays exercised in every
environment. Verified: fails on the previous code under `=zig`, passes
with and without the variable now.

* fix(zig): declare the Union relation pairs — analyze aborted on any union

`gitnexus analyze` exited 1 on every Zig repository that declares a
`union` (including the zig-basic fixture itself): the member-ownership
commit made `union_declaration` a MEMBER_OWNER, so HAS_PROPERTY /
HAS_METHOD edges are emitted FROM a Union node, but `Union` was not in
LINKABLE_LABELS, so the schema's scope-bridge cross product never
generated a `FROM Union` pair and LadybugDB rejected the edge
(`labelPair: "Union|Property"`). Resolver tests stayed green because
they never write to the DB.

- `Union` joins LINKABLE_LABELS (also bridges `Tag{…}` constructor
  references); the three hand-written `→ Union` target pairs move to the
  generated half, per the STRUCTURAL_PAIR_DDL rule.
- structural-pair-coverage gains an optional-grammar corpus with
  zig-basic (`Union|Property`, `Union|Method` sentinels), skipped when
  the grammar is absent.
- Rust `union_item` note updated: the three gates it cited are widened.

Note for reviewers: the DDL fingerprint changes (#2808), so existing
indexes are rebuilt on next analyze.

* feat(zig): resolve path deps through the dep's build.zig and src/root.zig

The bare-name resolver only knew `src/<name>.zig` and `src/main.zig`.
`zig init` has written `src/root.zig` for libraries since 0.12, so the
default library layout never resolved. Now: the root the dep's own
build.zig declares (`b.addModule("<name>", .{ .root_source_file =
b.path("…") })`, name-matched module first), then src/root.zig,
src/<name>.zig, src/main.zig. `normalizeZigDepPath` is shared by the
loader and the resolver.

* feat(zig): Const/Variable defs, member imports, receiver typing, generic type constructors

Coverage gaps found by indexing idiomatic Zig against the branch:

- Const / Variable nodes: ZIG_QUERIES had no @definition.const /
  @definition.variable, so `pub const VERSION`, error sets and type
  aliases were absent and zigVariableConfig never ran. Rules are gated on
  the literal `const` / `var` keyword — tree-sitter-zig 1.1.2 parses
  statement assignments (`x = 5;`, `x += 1;`, `_ = expr;`) as keyword-
  less `variable_declaration`s, and the scope query minted a phantom
  local per assignment and one `_` per discard. Container and @import
  bindings are skipped via `shouldSkipDefinitionCapture`.
- Imports: `const X = @import("x.zig").X` (named / alias), `const X =
  ns.X` where `ns` is an @import binding of the file (promoted to a
  named import), and `pub usingnamespace @import(...)` (wildcard, with
  `expandsWildcardTo`). All three lost the file-level IMPORTS edge.
- Receiver typing: `var x: T = undefined` / decl literals `const x: T =
  .init()` (annotation), `var c = T.init()` / `mod.T.init()` (call
  return), `List(u8){}` (instantiation literal); `normalizeZigTypeName`
  drops the comptime argument list.
- Generic type constructors `fn List(comptime T: type) type { return
  struct {…}; }`: the returned container is a Struct/Union/Enum named
  after the fn, owns its members (HAS_METHOD / HAS_PROPERTY), binds in
  the module scope beside the Function def, and is emitted ahead of it
  so a named import binds the type.
- `export` vs `pub`: `visibility` is now `pub`-only (Zig-module fact);
  `isExported` keeps `pub|export` (visible outside the unit, as C's
  external linkage). `export fn` without `pub` is not reachable from
  other Zig files.
- Extractor configs share `zigContainerName`; ast-helpers' owner walk
  learns the type-constructor shape.

Tests: zig-idioms fixture (10 resolver cases), extractor/interpret unit
cases for each rule.

* fix(zig): address sixth gitnexus-check review pass

- Windows absolute `.path` deps (`C:\x`, `C:/x`) return null from
  `normalizeZigDepPath` like POSIX ones; a `/`-only check let them
  through as repo-relative.
- `parseZigBuildZon` accepts the `.dependencies = .{` header only at
  brace depth 1 (a direct field of the file's `.{`), so a same-named
  field nested in an earlier struct cannot hijack the block.
- `importsExecuteWhereWritten: false` on the provider: `@import` is
  compile-time name lookup (as C `#include`, Rust `use`); a body-level
  `@import` is no longer marked `runsOnlyWhenCalled`.
- Namespace imports record the MODULE as `importedName`
  (`zigModuleNameOf`: last path segment without `.zig`), per the shared
  contract; the local handle stays `localName`.
- Keyword-less `<ident> = @import(…)` (`_ = @import("x.zig")` in a test
  block) is a `side-effect` import: file edge, no binding. Only
  `const`/`var` declarations bind a name or feed alias promotion.
- `extractZigFunctionName` doc: an empty name is falsy, so the enclosing-
  function walk skips the test node and continues to the File; it does
  not "end" there.

Not re-fixed: "DIR_LANG has no zig entry" — carried over for the fourth
pass in a row; `test/helpers/literal-collectors.ts` has had `zig` in
`DIR_LANG` (line 91) and `BASENAME_LANGS` since the second-pass commit.

Regression tests: absolute-path spellings, nested `.dependencies`
decoy, namespace/side-effect interpretation, function-scoped `@import`
not deferred (all four fail on the previous source).

* fix(zig): address seventh gitnexus-check review pass

- The scope query's `@import` binding rules are keyword-gated (`"const"` /
  `"var"`, first-child anchored) like every other binding rule, and the
  keyword-less `<ident> = @import(…)` statement has its own
  `@import.side-effect` rule. Tree-sitter queries cannot express "no
  keyword child", so that rule also matches the keyword shapes and
  `emitZigScopeCaptures` drops those (they are the binding rules'
  matches). Behaviour is unchanged from the sixth-pass fix — the existing
  side-effect test covers it — the query text now carries the guard the
  finding asked for.

Not re-fixed: "DIR_LANG has no zig entry" — fifth pass in a row;
`test/helpers/literal-collectors.ts` has had `zig` in `DIR_LANG` since
the second-pass commit. Left for a human reviewer to close.

* fix(zig): resolve @import of the repo's own build.zig modules (F3)

Bare-name imports were resolved through build.zig.zon path deps only, so
the module a repo's ROOT build.zig declares for itself —
`b.addModule("lightpanda", .{ .root_source_file = b.path("src/lightpanda.zig") })`,
imported by name from 378/567 Lightpanda files — never produced an IMPORTS
edge, and nothing reached through `lp.X` resolved. A repo with a build.zig
but no build.zig.zon got no resolution config at all.

- language-config: `parseZigRootModules` (static scan of the root build.zig:
  `addModule("<name>", …root_source_file = b.path("<p>.zig")…)`, and
  `createModule`/`addModule` bindings named via `addImport("<name>", m)` or
  `.imports = &.{ .{ .name, .module = m } }`; generated / `.url` / computed
  modules are skipped) → `ZigBuildZonConfig.rootModules`.
- `loadZigBuildZon` → `loadZigBuildConfig`: reads the zon AND the root
  build.zig; null only when neither contributes.
- resolver: root modules are consulted before path deps; std/builtin/root
  still never resolve.
- fixtures: zig-idioms gains a Lightpanda-shaped root module (+ decoy
  `addOptions().createModule()`); new zig-rootmodule (build.zig, no zon).

Corpus (Lightpanda): IMPORTS 3014→3389 (378 edges to src/lightpanda.zig,
was 0), CALLS 13885→13989, ns.f() 79.3%→83.3%,
param.m() type=ns-qualified 43→46/417.

* fix(zig): import every @import in expression position; resolve @import("x").f()

Both query sets only saw `@import` as the value of a const/var or under
`usingnamespace`, so an @import in any other position produced no file
edge: Lightpanda's `pub const Interfaces = .{ @import("a.zig"), … }`
registration table (288 modules), call arguments
(`CounterEnum("size", @import("ArenaPool.zig").BucketSize)`), comparison
operands (`JsApi == @import("x.zig").JsApi`) and member-call receivers
(`try @import("dump.zig").root(...)`) — 417 of 3,401 in-repo import pairs
had no IMPORTS edge, and the 80 inline-receiver calls resolved 0 times.

Scope query: a catch-all `@import.inline` rule matches every `@import`
builtin; `emitZigScopeCaptures` drops the ones a binding rule (or the
keyword-less side-effect rule) already claimed (by string-node id) so a
bound import is never doubled, emits the rest as side-effect imports once
per distinct source per file, and binds a member-call receiver as a
namespace import whose local name is the builtin's own text — the
`@reference.receiver` text on that call is identical, so the shared
namespace-receiver lookup (Case 1) resolves the member in the imported
module.

ZIG_QUERIES: the three variable_declaration/usingnamespace-anchored
`@import` rules collapse into the same single builtin rule (the structure
phase only skips import matches; one match per builtin keeps
tree-sitter-languages' exact-capture assertion intact).

Lightpanda corpus (zig-corpus-check, before → after): IMPORTS 3014 → 3426,
in-repo pairs missing 417 → 5 (4 under a default-ignored `cache/` dir, 1 a
commented-out import the census regex counts), `@import(..).f()` 0/80 →
72/80 (the 8 left are `@import("root")` and non-import builtins the census
mislabels), CALLS 13885 → 13959; every other line unchanged.

* feat(zig): model file-structs — a file with top-level fields is a Struct named after the file

In Zig every file is a struct; one that declares top-level fields is an
instantiable type whose name is the file stem (`Page.zig` declares `Page`,
`@typeName` agrees), and its top-level `fn`s taking `self` are its methods.
Lightpanda spells 413 of 567 files this way and, before this, `page.getArena()`
on a `page: *Page` parameter resolved 23 of 993 times (2.3 %) — `impact` on
`Page.getArena` reported 0 callers for 159 call sites, and 2,395 top-level
fields were ownerless Property nodes.

Definition phase: `((source_file (container_field …)) @definition.struct)` +
the class extractor names it from the file path (`zigContainerName(source_file,
filePath)`); top-level fns/fields are owned through the new
`LanguageProvider.resolveFileTypeOwner` hook (consulted by
`findEnclosingClassInfo` when the walk reaches the tree root, and by the
method/field extractors' owner lookup) — ids become `Method:<file>:Page.getArena#0`
/ `Property:<file>:Page.session` with HAS_METHOD / HAS_PROPERTY edges.

Scope phase: `emitZigScopeCaptures` emits a Class scope over the whole file
(same range as the Module scope, nested under it — the pair `canParentScope`
already admits) plus a Struct def anchored on it; member NAME bindings are
hoisted back to the Module scope by `zigBindingScopeFor` so `Page.init()`
(namespace member) keeps working, while ownedDefs stay in the Class scope so
`populateClassOwnedMembers` stamps the owner. The file-level `const Page =
@This();` alias no longer mints a Const (it would shadow the Struct); `@This()`
aliases in type position (`self: *SigHandler` in Sighandler.zig, nested
`Self`) are rewritten to the container name so receivers resolve. A namespace
import of a `.zig` file gets a NAMED twin of the file stem so `x: *Page` in the
importer binds the type as well as the module.

Shared, additive: `resolveFileTypeOwner` hook; `filePath` threaded to
`ClassExtractionConfig.extractName` / `extractOwnerName`; nameless
`definition.struct` passes `getLabelFromCaptures` like `definition.class`
already did (extractor synthesizes the name).

Lightpanda corpus (zig-corpus-check): param receivers typed by a file import
23/993 → 993/993; `self.m()` 99.2 → 100 %; annotated locals 11.6 → 23.2 %;
CALLS 13,885 → 15,689; HAS_METHOD 1,477 → 8,003; ownerless Property 2,395 →
276; Function/Method 8,378/1,518 → 2,562/7,330; no row regressed.
Fixture `zig-filestruct` (Page/Session/Sighandler/util) + unit tests pin the
shape, the stem naming, the alias rewrite, the namespace twin and the
unchanged namespace-file behaviour.

* test(zig): expression-position import case sees the file-struct type twin

* fix(zig): stop reading member calls `x.f(arg)` as direct calls named `f`

tree-sitter-zig spells `field_expression` as `object:`/`member:`; the shared
callable-flow reader only knew `property`/`field`/`method`, so every Zig
member call collapsed to a DIRECT call named after the member and the
solver fanned each argument out to every same-named callable
(4,761 cap warnings on Lightpanda, `Global.deinit -> Global.deinit`
self-loops through `pub const release = deinit;`).

Shared (grammar-neutral, receiver-gated):
- `memberParts` also reads `member` (only C/C++ `offsetof_expression` and
  JS `class_body` expose that field, without a receiver field).
- A member call is a field-stored-callable invoke only when a MEMBER store
  (`o->run = handler`, `self.f = target`) or a declared callable-typed field
  is visible — a same-named plain binding no longer gates it.
- `direct-callee-name` requires a direct designator: `.init(x)`,
  `' '.join(x)`, `string.Join(x)` name no callee to seed by simple name.
Zig: formals are numbered without the leading `self`, so `r.run(target)`
joins `cb` and yields `Runner.run -> target`.

Goldens for python/csharp regenerated: the only drift is the dropped
`direct-callee-name` on `' '.join(...)`, `text.strip().ljust(...)`,
`string.Join(...)`.

Lightpanda: cap-warnings 4761 -> 2, cvf self-loops 10 -> 0,
CALLS 13885 -> 13857 (28 removed, all callable-value-flow: 10 self-loops,
17 same-name fan-out, 1 lost `on -> TypeErased.start`; +1 correct
`Arena.alloc -> allocator`).

* fix(zig): bind container field types so `self.field.m()` resolves (F5)

A container's field types were never bound on its Class scope: the scope
query's `container_field` rule captured only the name, and
`emitZigScopeCaptures` synthesized no `@type-binding.field` group. The
compound resolver reads member types from that scope
(`typeOfMemberOnClass` → `classScope.typeBindings.get(field)`), so
`self.session.name()`, `self.counter.incr()` — Lightpanda's dominant
cross-object call shape — resolved 9 of 2803 times (0.3 %).

- query.ts: capture `type: (_)? @declaration.field-type` on
  `container_field` (enum variants have none).
- captures.ts: per typed field, push a `@type-binding.field` group (name =
  field, type = the type text, `@This()` aliases rewritten to the container
  name like parameter types); anonymous inline containers are skipped. The
  binding lands on the container's Class scope — the file's Class scope for
  a file-struct — since `zigBindingScopeFor` hoists only declaration names.
- query.ts/captures.ts: `const page = self.page;` / `var s = self.session;`
  one-level field aliases become `@type-binding.alias` bindings whose "type"
  is the RHS path; the resolver's member-alias branch re-resolves it as a
  receiver chain. Import aliases (`const Counter = counter.Counter;`) are
  dropped — they are named imports.
- interpret.ts: `@type-binding.field` → 'annotation',
  `@type-binding.alias` → 'assignment-inferred' (an annotation on the same
  binding wins).

Corpus (Lightpanda, zig-corpus-check): self.field.m() 11/2803 (0.4 %) →
1433/2803 (51.1 %); ident.m() bound=local-field-access 29/1902 (1.5 %) →
307/1902 (16.1 %); chain.m() 146/5022 (2.9 %) → 642/5022 (12.8 %);
CALLS 15838 → 18066. self.m() / free f() / ns.f() unchanged.

Tests: unit (zig-extractors) — one @type-binding.field per typed field with
sigils stripped and aliases rewritten; the binding hosted on the container's
Class scope (file-struct: the file's Class scope, not Module) with the
written spelling as declaredSpelling; field aliases bound to the RHS path
and never for import aliases. Integration (zig-idioms `holder.zig`,
zig-filestruct `Page.zig`): `viaField → incr` ×2 into counter.zig,
`viaAlias → get/twice`, `sessionName → name` / `sessionLabel → name` into
Session.zig. All fail without the change. The optional-payload capture
`if (self.opt) |c| c.incr()` is not asserted (F6).

* fix(zig): `pub const X = @import(…)` at file scope republishes X (reexportsName)

Lightpanda's `lightpanda.zig` is one long list of `pub const Arena =
@import("Arena.zig");`, and most files name their types through it (`const
lp = @import("lightpanda"); const Arena = lp.Arena;`, `arena: *lp.Arena`).
The scope side treated those bindings as plain imports of the hub file, so
the hub never published the names it re-exports and a third file's `const
Arena = lp.Arena;` (promoted to a named import of `Arena` from the hub) found
nothing.

`emitZigScopeCaptures` now marks named/alias import groups whose declaration
is a file-level `pub const` — the `@import(...).X` form, the alias promotion
`pub const Bar = ns.Bar`, and the file-struct type twin of `pub const Arena =
@import("Arena.zig")` — and `interpretZigImport` sets the shared contract's
`reexportsName: true` on them (the Python `__init__.py` shape, consumed by
`buildReexportClosures`). Private and fn-local bindings stay unflagged.

Not covered here: a receiver ANNOTATED with the dotted hub path (`arena:
*lp.Arena`) — Case 3 of the receiver-bound pass looks the member up with
`findExportedDef`, which only sees locally declared names; following
re-exports there is a shared change left for a follow-up.

* fix(zig): type receivers through `const X = <type expr>;` aliases (F7)

`const LocalAlias = Local;`, `const T2 = Thing;` (alias of an alias/import)
and `const B = util.List(u8);` (an INSTANTIATED generic type constructor)
were plain `@declaration.variable` bindings, so `LocalAlias.mk()`,
`var l = LocalAlias.mk(); l.go()`, `T2.make()`, `B.init()`, `B{}` and
`var x: B` all typed nothing (review repro r3-flow b1..b9; Lightpanda:
`pub const Proto = HtmlElement;` x68, `const Allocator = std.mem.Allocator`
x104, `pub const KeyIterator = GenericIterator(...)`, fn-local
`const R = ...(...)`).

Model: a `@type-binding.alias` binding of the alias NAME to the value's type
text — Rust's `let x = y` / JS's `const B = Foo`, source
'assignment-inferred' — NOT a TypeAlias def. Reasons: (1) the shared
machinery already chains typeBindings (`followChainedRef` in the extractor,
`followChainPostFinalize` after propagation), so `var l = LocalAlias.mk()`
and `var x: B` reach the target through the alias with no new shared code;
(2) nothing shared follows a `TypeAlias` def to its target — `isShapeLike`
only makes the alias itself a member owner (TS object-type aliases) — so a
relabel would have needed language-named shared code; (3) graph node ids
are UNCHANGED: every alias stays `Const:<file>:X`. `normalizeZigTypeName`
already drops the comptime arguments, so `util.List(u8)` binds `util.List`
and resolves through the namespace import (Case 3). The identifier /
member shapes also take `var` (`var cur = orig; cur.go()` — the cursor
idiom, same binding as Rust's `let x = y`).

Heuristic, stated as such: a CALL value is kept only when the callee's last
identifier is TitleCase (Zig's naming convention for types), because the
grammar cannot tell `util.List(u8)` from `util.makeThing()` and the latter
belongs to the call-return rules; the call-return group is dropped for the
same TitleCase shape so the two never race on match order. Import bindings
(`const Stack = @import("x.zig").Stack`), promoted namespace-member aliases,
enum/decl literals (`.foo`) and the `type:` annotation of
`var b: T = undefined;` are excluded.

Not done: the two-hop `pub const bridge = js.Bridge(T); bridge.accessor()`
chain. `js.Bridge` is a Function that RETURNS `bridge.Builder(T)` (a call,
not a container), so the alias binds `js.Bridge`, Case 3 finds a Function
with no members in js.zig, and Case 3b is skipped for a namespace head.
Following that hop needs a namespace-member return-type route in shared
code (or a Zig `resolveQualifiedReceiverMember` hook that re-implements
member lookup without the model); left for a follow-up.

Corpus (Lightpanda, `harness/zig-corpus-check.mjs`): CALLS 15838 -> 16051
(+213, 0 removed), `ident.m() bound=local-alias` 6/63 -> 36/63,
`local-call` 159 -> 176, `module/unknown` 110 -> 116, `local-other`
271 -> 273; `self.m()`, `free f()`, `ns.f()` unchanged or up.

* fix(zig): one alias rule set — F7's alias rules subsume F5's field-access alias rules

* fix(zig): type locals through try/catch/orelse, return types and payload captures

F6 of the gitnexus-check review. Three gaps in the value flow that types a
local receiver, all measured on Lightpanda:

1. `@type-binding.call-return` needed the `call_expression` as the DIRECT
   value child, so `const p = try Page.init(…)` (2,551 sites), `… catch
   return` (410) and `… orelse return` typed nothing. The rule is now one
   keyword-gated declaration match; `emitZigScopeCaptures` unwraps `try`,
   `catch`, `orelse` and parentheses (`zigUnwrapValue`) and decides what the
   value types (`zigCallReturnTypeOf`): a module-level receiver still names
   the type (`Counter.init()` → Counter, Rust `Foo::new()`); a free call
   binds the callee name (`makeThing`); a member call on a fn-LOCAL receiver
   (parameter / local / payload — Zig forbids shadowing, so "declared in the
   fn" is exact) binds the compound `node.asElement()` the shared resolver
   walks to the method's return type — instead of typing `el` as `Node`. A
   TitleCase callee (`List(u8)`) is a type constructor and binds nothing.

2. No `@type-binding.return` existed. `fn make() !*Thing` now binds
   `make ↦ Thing` in the enclosing scope (Module for free fns, the container's
   Class scope for methods, where the compound resolver reads it). Builtins,
   `type`, `@TypeOf(…)` and comptime type parameters (`?*T`) bind nothing;
   `@This()` / `Self` returns name the container. `normalizeZigTypeName` now
   strips the error union BEFORE the payload's sigils, so
   `Allocator.Error!*Page` → `Page` (it used to leave `*Page`).

3. Payload captures had no binding at all. `populateZigRangeBindings`
   (registered as `populateRangeBindings`) types `for (items) |it| / |*it|`,
   `for (items, 0..) |it, i|`, `if (opt) |v|`, `if (call()) |v|`,
   `while (it.next()) |x|` from the SUBJECT's written type minus one layer
   (`[]T` element, `?T` payload) — declining when the layer is not visible
   (`ArrayList(T)`) — and the same projection for `const t = items[i]` /
   `opt.?` / `ptr.*`. `catch |err|` and `switch` prongs are skipped.

Corpus (Lightpanda, gate before → after): CALLS 15838 → 17853;
`ident.m() bound=local-try/catch/orelse` 11/1298 → 584/1298;
`local-call` 159/1282 → 398/1282; `payload` 82/1085 → 233/1085;
`other-recv:call_expression` 5/991 → 457/991; `local-other` 271 → 364;
`self.m()` 100 %, `free f()` 97.5 %, `ns.f()` 83.4 % unchanged; nothing down.

Not covered: `const t = ns.f()` (a namespace fn's return type across files —
Case 3 has no path from a namespace head to a callable's return binding),
and expression receivers (`items[i].run()`, `o.?.run()`).

* fix(zig): resolve leftover fixture merge markers (Page.zig)

* fix(zig): reconcile F6 value inference with F7 aliases and F5 field bindings

- A fn-local TitleCase receiver (`const R = generic.List(u8); var l =
  R.init();`) is a type alias (F7), not a value local: `R.init()` names the
  type `R` like `Counter.init()` does at module level, so `l` chains
  R → util.List → push. F6's local-receiver rule now excludes TitleCase heads.
- The F6 unit helper only collects the value-inferred / return kinds it
  owns; F5 field and F7 alias bindings for the same names are asserted in
  their own suites.

* fix(zig): give function-local and anonymous containers an identity (F8)

`const R = struct {…}` declared inside a fn (Lightpanda's reflection.zig
has ~20, one per builder) all collapsed onto one `Struct:<file>:R` with one
`R.get`; anonymous containers (`std.sort.pdq(…, struct { fn lessThan … }
.lessThan)`, `const byte_size = struct { fn it … }.it;`, `?struct { min,
max }` field types) had no identity at all, so their fns were OWNERLESS
Methods (`Method:<file>:lessThan#3`) that collided across a file.

`zigContainerName` now yields the graph IDENTITY on both phases:
  - function-local named: `<enclosing callable>$<name>` — `Reflect.string$R`
    (Java local-class `$` chain; `populateClassOwnedMembers` leaves it whole);
  - anonymous: `<host>$<ordinal>` — `build$1`, `Outer$1`, `Page$1`
    (javac's `Outer$1` numbering per host, in source order);
  - a `test` host is keyed `test@L<line>` (its string does not survive the
    class extractor's qualified-name normalization).
`zigContainerBindingName` keeps the spelling code writes (`R`) for scope
bindings and `@This()` alias rewrites (`@declaration.binding-name`).

Structure phase: bare `(struct|enum|union|opaque_declaration)` rules mint the
local/anonymous nodes via the class extractor; `shouldSkipDefinitionCapture`
keeps exactly one rule per container (`zigContainerAnchor`); a new
grammar-neutral `resolveContainerTypeOwner` provider hook lets the shared
owner walk name a container from context, so `Method:<file>:Reflect.string$R
.get#0` and its HAS_METHOD source agree by construction. Scope phase: the
wrapper group splits name/binding-name for locals and anonymous containers
get synthesized `@declaration.<kind>` defs (`is-synthetic`).

Lightpanda: ownerless Methods 14 → 0, fns without a node 55 → 0, ownerless
Properties 276 → 5, HAS_METHOD 8003 → 8074, HAS_PROPERTY 7275 → 7403,
CALLS 15838 → 15857, Struct 1905 → 2199; no resolution bucket dropped.

* fix(zig): re-add the implicit receiver on the call side so both method-call spellings reach the callback formal

`extractFunctionParameters` sliced the leading `self` off the formals, which
lined up `r.run(target)` (target@0 ↔ cb@0) but lost the explicit spelling
`Runner.run(&r, target)` (&r@0, target@1 ↔ cb@0): the callback never joined
its formal and `run → target` was missing (PR #1432 review by koriyoshi2041).

Formals are numbered once per function while the receiver differs per call
shape, so the fix lives in `extractCallArguments`: keep `self` as formal 0
and prepend the receiver as actual 0 when the callee is a member call on a
VALUE receiver — chain head is a fn-local name that is not TitleCase, the
same value-vs-type rule F6 uses. Namespace / type / decl-literal receivers
(`Runner.init(cb)`, `helpers.apply(cb)`, `List(u8).init`, `.init(cb)`) get
no prepend. Known residual gap, documented: a module-level value receiver
(`global_runner.run(cb)`) is not fn-local and still misses.

Tests: the F2 integration case now asserts both spellings plus a namespace
call; the unit contract pins `self@0, cb@1` and the per-call actual index.

* fix(zig): address eighth gitnexus-check review pass

- Named dependency modules: `parseZigBuildModuleRoots` scanned
  `addModule("<name>", .{ … })` with a `[^}]*` regex, so a nested field
  before `.root_source_file` (`.imports = &.{ .{ … } }`) ended the match
  at the inner `}` and demoted the module to an unnamed fallback — the
  first exe/lib root in the file then answered `@import("<name>")`. The
  named lookup now walks the balanced `addModule(…)` argument list
  (same scanner as `parseZigRootModules`, comment-stripped, string-aware);
  the unnamed fallbacks are unchanged. Regression test in
  `zig-import-resolver.test.ts`.
- Type-position `@import`: `var x: @import("m.zig").T = undefined;` was
  read as an import binding of `x` on both sides — the query rules match
  the `type:` child like a value, and `isZigContainerOrImportBinding`
  scanned every named child — so `x` was never declared and became a
  named import of `T`. The helper now skips the `type:` field, and
  `emitZigScopeCaptures` drops binding-rule matches whose `@import` sits
  in the annotation (`isZigTypePositionImport`) without claiming the
  source, so `x` binds as a variable and the file edge survives as a
  side-effect import. Regression tests in `zig-extractors.test.ts`
  (variable extractor + scope captures).
- Union in the class-capture skip guard: the parse-worker's inline
  class-like predicate lacked `Union`, so a `Union` definition bypassed
  `shouldSkipClassCapture` unlike every other `ClassLikeNodeLabel`.
  Added the label; no Zig behavior changes (Zig defines no skip hook), so
  no test.
- File-owned method ids in `findEnclosingFunctionId`: the arity lookup
  used `findEnclosingClassNode` while the owner came from the file-owner
  aware `cachedFindEnclosingClassInfo`, so a Zig file-struct's top-level
  fn produced `Method::Page.get` without the `#<arity>` suffix. It now
  uses `findEnclosingClassNodeOrFileOwner`, the definition-phase lookup.
  Consistency fix only: `ParseWorkerResult.calls` / `.assignments` (the
  sole consumers of this id) are merged but not read since #942 — CALLS
  edges come from the scope pipeline, whose ids were already right — so
  no observable graph change and no test.

Not re-fixed:
- `test/helpers/literal-collectors.ts` `DIR_LANG` has no `zig` entry
  (raised for the seventh time): the entry exists (`zig:
  SupportedLanguages.Zig`, added by the second-pass commit), so
  `languages/zig/**` literals are already validated against the Zig
  grammar alone; documented in the PR body since the fifth pass.

* fix(zig): keyword-gate the constructor type-binding rules

The three `@type-binding.constructor` rules (`const p = T{…}`, `mod.T{…}`,
`List(u8){…}`) matched any `variable_declaration` with an identifier and a
`struct_initializer`, keyword or not — and tree-sitter-zig 1.1.2 parses a
re-assignment `p = T{…};` (and `_ = T{…};`) as the same node type. So an
assignment minted a constructor binding for `p` in its own block, and one
for `_`. Zig's static typing makes the extra binding redundant (`p`
already carries its type from its declaration: annotation, constructor or
inferred value), so it cost little, but it declared nothing and stood out
against every other binding rule (`@declaration.variable`, the import
rules, the call-return rules), which are keyword-gated for exactly this
shape. Split each rule into `"const" .` / `"var" .` variants, like the
call-return rules.

Regression test in `zig-extractors.test.ts`: `p = T{…}`, `q = mod.T{…}`,
`l = List(u8){}` and `_ = T{…}` after their declarations yield only the
three declaration bindings (fails on the previous query). The zig,
callable-value-flow, grammar-literal and tree-sitter-languages suites are
unchanged.

Raised twice by gitnexus-check (passes on 2026-08-18 12:42 and 12:56).

* fix(zig): re-baseline the callable-flow capture fingerprints, keep `await f<T>(x)` a direct callee

The `benchmarks (GITNEXUS_BENCH)` CI job gates two capture fingerprints
that this branch's shared callable-flow change (3e62b99a) moved without
re-baselining: `bench/python-scope/baseline-fingerprint.txt` and four
languages in `bench/scope-capture/baselines.json` (csharp, cpp,
typescript, kotlin). Both `--check` runs pass on origin/main and failed
on this branch; every other language matched its baseline on the same
run.

Drift, verified by dumping the canonical matches on both trees:
- csharp / kotlin / python: exactly the intended change — a MEMBER call
  (`string.Join(x)`, `.forEach { }`, `' '.join(x)`, `.ljust(w)`) no
  longer carries `direct-callee-name`; the argument fact is unchanged.
- cpp: `choice.select(1)` (cpp-deleted-overload) drops an INDIRECT
  invoke + its synthetic `@reference.call.free` that were gated only by
  the same-named free `select` binding; the site is a genuine method
  call already captured as `@reference.call.member`. capture_groups_fp
  4605 -> 4601.
- typescript: `await svc.verify<T>(x)` (member) and `initializer()(cb)`
  (call-of-call) drop the name as intended. But `await verifyToken<T>(x)`
  — a DIRECT call — lost it too, because tree-sitter-typescript parses
  `await f<T>(x)` as `call_expression(function: await_expression(f),
  type_arguments, …)` and the new direct-designator gate saw an
  await_expression, not `f`. `wrappedExpression` now unwraps
  `await_expression` (no named field, so the field-based unwrap missed
  it), restoring parity with main for the direct spelling while the
  member spelling stays nameless. Regression test added; it fails
  without the unwrap on both assertions.

Gates run locally: scope-capture --check (15 languages), python-scope
--check, import-target --check, tsc, eslint, prettier, the callable-flow
/ golden / tripwire / resolver test files (33 files), full suite with
coverage (82.9/71.5/89.1/86.4 vs 26/23/28/27 thresholds).

* test(zig): fail CI when the optional Zig grammar is absent

`@tree-sitter-grammars/tree-sitter-zig` is an optionalDependency, so every
Zig suite gates on `isLanguageAvailable(Zig)` and the ABI load-smoke accepts
a clean load failure for an optional grammar. Both are the right contract for
a platform with no prebuild, and together they leave a hole: if the grammar
never installed on any CI runner, this PR would merge with all eight Zig
resolver suites plus the structure-phase suite reported green-by-skip, having
never executed the native Zig parser once.

Close it with the `GITNEXUS_REQUIRE_FTS` idiom already used for the FTS
suites. `GITNEXUS_REQUIRE_ZIG=1` declares "this runner has a prebuild, the
grammar MUST be here", and a missing grammar becomes a failure instead of a
skip. tree-sitter-zig@1.1.2 publishes prebuilds for {darwin,linux,win32}-
{x64,arm64}, so the flag is set on two required jobs that all run on covered
platforms: the sharded ubuntu `tests` job and the three-OS `abi-assert` job.

- test/helpers/optional-grammar.ts: the registry mapping a language to its
  require-variable, plus `describeGrammarPresence`, a presence assertion that
  FAILS when required-but-absent. Deliberately a separate test rather than
  flipping the suites from skip to fail: a skipped suite reports success, so
  only a failing test can turn "Zig never ran" into a red job.
- parser-loader-abi.test.ts: the optional exemption is revoked for a language
  the environment declares required, so an ABI-broken Zig binding fails the
  smoke instead of passing as a clean absence.
- optional-grammar-gate.test.ts: pins the two ways the gate could silently
  never fire — reading a variable name CI does not set, or accepting a value
  CI does not write.

Nothing changes for a run that leaves the variable unset: local runs and any
future prebuild-less platform still skip. Verified both directions --
`GITNEXUS_REQUIRE_ZIG=1` alone: 149 passed, 0 skipped; with
`GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1` forcing the grammar away it fails 2 tests
with an actionable message; with the skip flag but no require flag it is
green-by-skip exactly as before.

Addresses the test-only blocker in the gitnexus-check review of #1432.

* fix(zig): type the optional-grammar gate by grammar key, not language

The gitnexus-check finding on parser-loader-abi.test.ts:155 is right, and
none of the gates caught it: `tsconfig.json` includes only `src/**/*`, so
neither `tsc --noEmit` nor CI typechecks the test tree, and vitest strips
types without checking them. Confirmed with a scoped tsc run over the file:
`error TS2345: Argument of type 'string' is not assignable to parameter of
type 'SupportedLanguages'`.

Not fixed with the proposed `key as SupportedLanguages` cast, which would
assert something false: `listGrammarSources()` yields one row per SOURCES
entry, including variants like `typescript:tsx` that are not enum members.
`isOptionalGrammarRequired` now takes the grammar KEY it is really given,
and the registry keeps a `satisfies Partial<Record<SupportedLanguages,
string>>` so every key we write is still pinned to a real language.

Two new cases cover the failure mode the type error was pointing at — a
registry key that can never match what the ABI smoke passes, leaving the
gate configured-looking and permanently inert: every OPTIONAL_GRAMMAR_ENV
key must be a key `listGrammarSources()` yields and must be marked optional
there, and an unregistered variant (`typescript:tsx`) must not be required
even with the variable set.

Same blind spot, two more latent errors in files this PR adds, both fixed:
`Parser.Language` is not an exported member (use the `setLanguage` parameter
type, as parser-loader-abi.test.ts already does), and the `ParsedImport`
filter did not narrow the union, so `localName` was read through a `!` on an
arm that has no such property — now a type predicate. The one remaining
error under the same probe, in `resolvers/callable-value-flow.test.ts:319`,
predates this branch (authored 2026-07-17, on main) and is left alone.

structural-pair-coverage's optional-grammar case switches from
`it.concurrent.each` to `it.concurrent.for`: only `for` passes the test
context as a second argument (`each`'s callback is `(...args: T[])`), and
that context carries the dynamic `skip()` the per-language gate calls.
Behaviour is unchanged — grammar present: 10 passed; grammar forced away:
9 passed, 1 skipped.

Whole test tree typechecking is a separate, much larger job: the same probe
over `test/**` minus fixtures reports 734 pre-existing errors across the
repo. Out of scope here.

* fix(zig): address tenth gitnexus-check review pass

- `normalizeZigDepPath`: normalize backslashes BEFORE the absolute-path
  check. A UNC dep (`\\server\share\dep`) used to slip past the check and
  normalize to the repo-relative `server/share/dep`; root-relative `\dep`
  had the same hole. Both now return null. Regression case added to the
  absolute-spellings test with the files those misreadings would resolve.
- `bindPayloads`: a pointer capture `for (pages) |*p|` now records `*Page`
  (declaredSpelling) instead of `Page` — the `*` is an anonymous payload
  child before the identifier. Method dispatch is unchanged (`rawName`
  strips the sigil), but a deref projection `const q = p.*;` now sees the
  pointer layer. New fixture fn `viaPtrCaptureDeref` + assertion; fails on
  the previous code (verified by stashing the src fix).
- `optional-grammar-gate.test.ts`: renamed the `typescript:tsx` case — the
  key IS a registry row; what makes it inert is the missing gate entry. Now
  also asserts a key no registry yields.
- `structural-pair-coverage.test.ts`: header updated — ten tables (not
  eleven) are absent from every rule's target side; `Union` left the set
  when Zig made it linkable.
- `language-classification.ts`: doc comment now names zig in the
  experimental set (added after Ring 1).

Not re-fixed (invalid findings):
- "owner-hook contract wired to an undeclared variable": stale-diff read —
  `findEnclosingClassInfo` declares `resolveFileTypeOwner` /
  `resolveContainerTypeOwner` as optional parameters (ast-helpers.ts:905,
  917) and parse-worker threads them at every call site; tsc compiles clean.
- "optional Zig grammar added unconditionally to the parsing fixture
  suite": the cited block only `fs.readFile`s the committed fixture file to
  assert it is non-empty — no parser or grammar load is involved.

* fix(scope-resolution): mark construction-site CALLS edges in reason (opt-in), enable for Zig

PR #1432 human review, item 2: a Zig struct literal `T{ .f = x }` (no
parens) is modelled as a CALLS edge to the type — the Rust `T { .. }` /
Go `T{}` shape — and nothing on the edge told it apart from an invocation
(`get_next_spawn → SpawnRequest` from seven `return SpawnRequest{ … }`).

`ScopeResolver.markConstructionSites` (default off): when set, the edge
emitted for a `callForm === 'constructor'` site gets ` (constructor)`
appended to its reason, in both emit paths — `local-call (constructor)` /
`import-resolved (constructor)` in the free-call fallback and
`scope-resolution: call (constructor)` in the reference bridge. The Zig
resolver opts in. `Reference` gains an optional `callForm`, copied from
the site by `buildReference`, so the bridge can see the form.

Why `reason` and not a property or edge type: relationships carry no
arbitrary properties, a new column changes the relation DDL and moves
SCHEMA_FINGERPRINT, and `reason` is the channel the IMPLEMENTS `-pointer`
receiver form already uses. Why opt-in: the unsuffixed strings are a
pinned contract asserted verbatim by the other language suites
(php/cpp constructor calls expect exactly `import-resolved`); every
non-Zig edge stays byte-identical.

Tests: `references-to-edges-call-form.test.ts` pins both vocabularies
and the default-off behaviour; `zig.test.ts` asserts
`Reflect.string → Accessor` / `Reflect.url → Accessor` carry
`local-call (constructor)` next to a plain invocation, and that every
marked edge targets a Struct.

* feat(zig): track qualified struct literals (`mod.T{…}`) as construction sites

PR #1432 re-test (issue comment on 97571d23): 163 qualified literals
`mod.Type{ … }` in a real project produced no CALLS edge at all, so only
same-file and imported-name literals were tracked as construction sites.

One query rule captures `(struct_initializer (field_expression object
member))` as `@reference.call.constructor` WITH the receiver. Captured as a
free constructor instead, the site resolves by its simple tail and a
workspace-unique `Thing` answers for `c.Thing{}` whichever module the
source named (measured: c.zig defines no `Thing`, the edge went to a.zig's).
With the receiver the site takes the receiver-bound namespace case — the
path `mod.fn()` takes — which resolves inside the module the receiver is
bound to: `a.Thing{}` / `b.Thing{}` bind their own files, `c.Thing{}` binds
nothing, `std.Thread.Mutex{}` binds nothing next to a local `Mutex`.

That case's edge now goes through `constructionSiteReason` too, so the
opt-in marker (`import-resolved (constructor)` / `global (constructor)`)
reaches it; `markConstructionSites` joins `ReceiverBoundProviderSubset`.
Byte-identical for every provider that does not set the flag.

Also answers the twelfth gitnexus-check pass: the `bodyNodeSet.size === 0`
guard on the extractor factories' no-wrapper branch is deliberate (a config
with wrappers whose node lacks one is a bodiless declaration); the two
comments now say so instead of reading as a universal last resort. Go's
method config, the only other empty-`bodyNodeTypes` config, never reaches
the branch (its `extract()` gates on method/function nodes the class-node
caller never passes).

Tests: new `zig-qualified-literal` fixture (same-named `Thing` in two
modules, a module without it, an external `std` qualifier next to a local
and an imported `Mutex`); `zig-basic` pins `pioneer.Pioneer{…}` and the
union `pioneer.Tag{…}` as marked construction sites.

* feat(zig): resolve hub re-exports, enum-variant receivers and type-named receivers (real-project audit)

Audit of three real Zig projects indexed with this branch (tigerbeetle 246
files, mach 132, ghostty 788): method reachability was 63 % / 35 % / 55 %,
and three shapes accounted for most of the misses.

1. Hub modules. Zig projects publish types through a file made only of
   re-exports (`pub const Terminal = @import("Terminal.zig");`, `pub const
   PRNG = @import("prng.zig");`, `pub const Thing = @import("thing.zig")
   .Thing;`). Such a file owns NO local binding, and `findExportedDef` reads
   local bindings only — so `terminal.Terminal.init()`, `t: stdx.Thing`,
   `var p = stdx.PRNG.from_seed()` and `h: stdx.BoundedArrayType(u8, 4)`
   all resolved to nothing. Measured before → after: CALLS into ghostty's
   `src/terminal/` from outside it 46 → 253 (150 `terminal.Terminal.` sites
   alone); into tigerbeetle's `stdx` hub from outside it 837 → 1500 (136
   static calls, 289 annotations). Method reachability: tigerbeetle
   2249 → 2272 of 3544, ghostty 2766 → 2865 of 5016, mach 1047 → 1051 of
   2967 (mach's hub publishes generic instantiations, `pub const Quat =
   q.Quat(f32)`, a shape this commit does not cover).
   `findExportedDefIncludingImportedNames` reads the finalized channel
   (origin import / namespace / reexport, def already resolved to the
   declaring file), refusing a name bound to two distinct defs. Opt-in per
   provider (`namespaceExportsIncludeImportedNames`): a module's imports are
   not its exports in most languages; Zig opts in because a hub member a
   consumer can name is public by construction. Used by receiver-bound Case
   1, Case 3, the compound resolver's namespace branch, and a new Case 2
   route that resolves a namespace-qualified class receiver (`stdx.PRNG`)
   through the same lookup.

2. Enum variants as receivers. `Operation.create_accounts.event_max()`
   (147 sites in tigerbeetle): a variant has no written type, but it has
   one — the enum itself. `emitZigScopeCaptures` now emits a field type
   binding per enum variant, so the field walk that already handles
   `self.session.name()` types `Op.create` as `Op`.

3. Receivers named after their type. `self` is a convention, not a rule:
   tigerbeetle writes `replica: *Replica` (777 of 1127 methods), mach
   `pool: *@This()` (764 of 833). Reading only `self` as the receiver
   labelled all of them `isStatic: true`, counted the receiver in their
   arity (`Counter.incr#1`) and sourced the scope binding as a plain
   parameter. `zigReceiverParameter` is the single rule for both phases:
   the FIRST parameter when named `self`, or typed as the enclosing
   container (`@This()`, its binding name, a `const X = @This();` alias),
   pointers / const / optionals stripped.

Fixtures `zig-hub` and `zig-receivers` pin each shape, including the
refusals: a private hub import does not leak, a foreign-typed first
parameter is not a receiver, a factory stays static.

* fix(zig): address thirteenth gitnexus-check review pass

- File-struct receivers named after the file stem were always static: the
  method builder called `isStatic` / `extractReceiverType` /
  `extractParameters` without the extractor context's `filePath`, so
  `zigReceiverParameter` could not name a file-struct (`fn add(ledger:
  *Ledger)` in `Ledger.zig`, no `Self` alias) and the fn came out static
  with the receiver in its arity (`Ledger.add#2`) — an id the scope side,
  which always has the path, never produces, so its CALLS edges went
  nowhere. `MethodExtractionConfig` now passes `filePath` as an optional
  trailing argument to those three hooks (same shape as
  `extractOwnerName`); the Zig config threads it through, every other
  config ignores it. Regression tests in `zig-extractors.test.ts` (unit)
  and `resolvers/zig.test.ts` (new `Ledger.zig` in the `zig-receivers`
  fixture: ids, `isStatic`, and the three CALLS edges); both fail on the
  previous source.
- `LINKABLE_LABELS` comment: the remaining `CLASS_KINDS` entries include
  `Namespace`.

Not re-fixed:
- "Ownerless-method assertion regex cannot match `.zig` graph IDs": the
  `[^:]+` segment consumes the whole file path (dots included) up to the
  second colon, and `[^.]+#\d+$` then matches only an owner-less name —
  `Method:src/Sorter.zig:lessThan#3` → true, `…:Sorter.sortBoth$1.lessThan#3`
  → false, checked with node.
- "Public namespace imports are never marked as re-exports": the shared
  `ParsedImport` namespace variant has no `reexportsName` field and
  `contributesReexportEdge` excludes namespace drafts on `base.kind` by
  contract; a `pub const X = @import("x.zig")` hub member is exposed
  through `findExportedDefIncludingImportedNames` instead, which is what
  the audit commit added for exactly that shape.
- "Private Zig namespace imports are treated as public hub exports": a
  private import cannot be named through the hub in code that compiles,
  and `findExportedDef` applies the same no-visibility rule to local
  defs; the finalized binding channel carries no `pub` bit to check.
- "Range binding mutates finalized scopes" and "unconditionally adds an
  optional Zig grammar to the fixture suite": refuted in the tenth and
  eleventh pass notes of the PR body, unchanged since.

* fix(zig): close the adversarial review's ten findings (8.2–8.12)

PR #1432 review 5095267917 on 34c53473 retained eight P1 and two P2
findings; each is reproduced on the new `zig-chains` / `zig-buildmodules`
fixtures with the decoy that made the old answer wrong, and pinned by a
test named after its number.

- 8.2 per-build-module import tables (`parseZigBuildModules`): a source
  resolves a bare name through its own module's `addImport` table (root
  file, else deepest root directory), fails closed when same-directory
  modules disagree, and follows `addImport("api", dep.module("core"))`
  through the dep's `addModule`; repo-wide names and zon deps remain the
  fallback.
- 8.3 module-level value receivers (`zigHostValueNames`) prepend the
  implicit `self` like fn-locals, so `global_runner.run(cb)` joins `cb@1`.
- 8.4 deep member aliases (`@import("lib.zig").B.work`, `lib.B.work`)
  keep the written owner: the module is bound as a namespace and the
  alias's use sites are rewritten to `receiver . member`; only one-level
  aliases are promoted to named imports.
- 8.5 container-hosted containers get owner-qualified identities
  (`A.Item`, `B.Item`, `Outer.Inner`), minted by the bare-container rule,
  while the scope keeps the lexical binding.
- 8.6 result-location `.init(…)` / `.{…}` under an annotation, a return
  type or a field type emit the call / construction site with the
  expected type as receiver.
- 8.7 Zig arm in bench/import-target (five dispatchers, config-free
  fingerprint) + baselines row; `--check` passes.
- 8.9 fn-local `@import` bindings and their uses are keyed per callable
  (`m$f_sib_a`), so sibling fns no longer share one namespace bucket.
- 8.10 `ScopeResolver.resolveNamespaceChains` (opt-in, Zig only): Case 1
  / Case 2 / Case 3 and the compound resolver walk a qualified receiver
  segment by segment — republished modules, nested types, enum variants
  through the module — refusing ambiguous hops. Off, every lookup keeps
  its one-hop split; the 70 resolver suites are unchanged.
- 8.11 `@import("a.zig").Thing{}` binds the module as a namespace in type
  position; `List(u8){}` / `lists.List(u8){}` get constructor sites.
- 8.12 a fieldless file whose top-level fn takes the file's own type
  (`self: *@This()`, `self: *Self`) is a file-struct; two over-matching
  ZIG_QUERIES rules are filtered by `shouldSkipDefinitionCapture`.

Also asserts the committed `opmod.Op.lookup.event_max()` call in zig-hub.

* fix(zig): address gitnexus-check findings on 215f70e3

- receiver-bound Case 3 wraps its reason in constructionSiteReason, like
  Case 1 and the nested-type route of Case 2 (one vocabulary per provider)
- resolveZigImportInternal rejects drive-qualified absolute imports
  (C:\foo.zig), the same test normalizeZigDepPath applies; unit case added
- the compound resolver's chain seed also tries the whole receiver as the
  qualified class (opmod.Op), as a bare class-name head already does
- markConstructionSites contract text names the receiver-bound routes

The return_type field claim is refuted: tree-sitter-zig exposes a fn's
return type as the type field (checked on the grammar).

* fix(zig): a build-module alias bound to an unindexed root fails closed

resolveThroughBuildModules returned undefined when the containing module
bound the alias to a file that is not indexed, which let the repo-wide
addModule map answer under the same name (gitnexus-check on 5299c552).
The module's table is the authority for its aliases: bound-but-unindexed
is null, only an unbound name falls through. Unit case with a same-named
repo-wide decoy, plus the outside-module file that still reaches it.

* fix(zig): an unindexed root module fails closed, never a same-named zon dep

The root build.zig's addModule declaration is authoritative for a bare
name when it binds it; a root that is not indexed used to fall through
to a build.zig.zon path dep of the same name — a different declaration
answering under the name (gitnexus-check on fe24b37f). Same rule as the
build-module tables. Unit case added.

* bench(receiver-resolution): rebaseline for the Zig lang-resolution fixtures

The receiver-resolution gate (#2856/#2899) landed on main after this branch
forked and counts call drops over test/fixtures/lang-resolution, which this
branch extends with the zig-* fixture projects. Regenerated with
`measure.mjs --update-baseline`: callDrops 102 -> 113, all 11 new drops in
.zig files, shape `no-chain`.

Every new drop is a call whose callee has no node in the corpus, not a
resolver regression: `std.Build.Module.addImport` in the three build.zig
fixtures (7, classified in-program), `std.sort.pdq` in Sorter.zig (2,
unknown), `std.Thread.Mutex{}` / `std.mem.Allocator{}` literals in
zig-qualified-literal (2, unknown, the fixture asserts std stays external),
and one `.init()` decl literal on a generic instantiation
(`const u: Stack(u16) = .init()`, in-program). Shape arm unchanged.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(typescript): anchor property_signature to declared shapes

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* test: replace assertions that cannot fail

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    export const tsRuntimeConfig = { tsConfigRetries: 3 };

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The layer, rather than a workaround:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

`route_map` on the reporting repo returned

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Three guards, catching different shapes:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

2. THE TIER NO LONGER LIES.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Measured against the real extractor before fixing:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

fix(schema): declare the full scope-resolution relation cross product (#2792) (#2793)
* fix(schema): declare the full scope-resolution relation cross product (#2792)

`RELATION_SCHEMA` was hand-listed, and every prior fix added only the
FROM/TO pair named in a crash report — `Const→Method` in #2769, the
Swift/Rust member pairs before it. So `analyze` kept aborting at
`assertDeclaredPair` on the next codebase whose edges happened to land on
a different pair; #2792 reports `Class→Variable` on Java.

Audit the surface instead of the symptom. `buildGraphNodeLookup` skips
any node whose label is not in `isLinkableLabel`, so the lookup holds
only linkable-labelled nodes — and both endpoints of every graph-bridge
edge resolve through that lookup. The emittable surface is therefore
exactly:

  FROM  LINKABLE_LABELS + File   (the module-level caller fallback)
  TO    LINKABLE_LABELS + CALL_TARGET_TYPES

`isCallerAnchorLabel` is a strict subset of linkable and contributes
nothing on top. `CALL_TARGET_TYPES` contributes `Delegate`, which
`tryEmitEdgeWithExplicitTargetId` can emit without going through the
lookup at all.

Generate that 14x14 block into the DDL rather than listing it: 223 -> 322
declared pairs, and no future pair from these sets can be missing by
construction. The containment/inheritance/DI/route/cluster/PDG pairs stay
hand-declared — no single predicate describes them.

Both label sets live in the ingestion layer, which `core/lbug` must not
import, so schema.ts carries twin lists. test/unit/schema-pair-coverage.ts
derives the requirement from the originals and fails CI when either set
grows without the pairs landing here — the piecemeal loop this fix ends.

Measured before widening: at 322 pairs the cost is inside noise
(1.09s vs 1.12s per 300 anchored queries on a 32-table DB), but the full
32x32 cross product is ~1.8x on untyped-endpoint anchored queries. The
audited subset is the right scope, not "declare everything".

INCREMENTAL_SCHEMA_VERSION 34 -> 35: LadybugDB fixes endpoint pairs when
the rel table is created, so a pre-v35 database physically cannot store
these edges.

Closes #2792

* fix(schema): declare the non-bridge structural pairs COBOL and Vue emit

The generated scope-resolution block closed the half of RELATION_SCHEMA a
label predicate can describe. The hand-declared half was still stale: with
#2791's Function->Variable fix applied, `analyze` continued to abort on this
repo's own test/fixtures/lang-resolution with

  Relationship label pair Module→Property is not declared

A full sweep (assertDeclaredPair patched to log-and-skip, run over the whole
fixture corpus) found 13 undeclared pairs over 106 edges. This branch already
covered 3 of them via the cross product; the remaining 10 come from emitters
outside the graph bridge:

  - cobol-processor.ts mints Module / Namespace / Record / Property /
    CodeElement and wires them with CONTAINS, CALLS and ACCESSES (9 pairs)
  - vue-sfc-extractor.ts emits BINDS_EVENT_HANDLER from a handler Function to
    the child component's File, the only edge whose target is a File (1 pair)

CodeElement, Namespace, Record and File are in neither scope-bridge label set,
so neither the generated block nor schema-pair-coverage.test.ts can reach them.

Adds test/integration/structural-pair-coverage.test.ts, which derives the
requirement from a corpus instead of a predicate: it runs the real pipeline
over the non-bridge fixtures and requires every FROM/TO pair they produce to
be declared. Mutation-checked — dropping `FROM Function TO File` fails it with
exactly Function|File.

Verified: cobol-app, vue-basic and php-transitive-traits now index instead of
aborting; the full lang-resolution corpus completes at 10,876 nodes / 18,517
edges; scrypster/muninndb at 0b7a4272 (the #2789 repro) completes at 20,069
nodes / 71,580 edges, matching #2791 exactly, so this supersedes that PR.

* refactor(test): simplify the structural pair coverage guard

Cleanup pass over the previous commit. No behaviour change to the schema.

- reuse `FIXTURES` and `runPipelineFromRepo` from resolvers/helpers.ts instead
  of re-deriving the fixture root and importing pipeline.js directly
- gate on `distWorkerExists()` like every other integration test that passes
  `workerUrlForTest`, so a missing dist skips rather than fails
- run the three fixtures with `it.concurrent.each`; they share nothing and the
  cost is almost all worker spawn plus grammar load, which overlaps well
  (tests phase 21-24s -> 5.6s measured)
- replace the sentinel-in-a-Set filter with a plain `.filter()` chain, matching
  the sibling unit test, and move the declared/table lookups off the per-edge
  path onto the deduped set
- move the pure string pin out of the integration tier into
  schema-pair-coverage.test.ts, where the identical construct already lives, so
  it needs no build and survives fixture deletion
- trim the schema and test prose that restated the code, and correct the
  BINDS_EVENT_HANDLER attribution: it is emitted by
  languages/vue/scope-resolver.ts, not vue-sfc-extractor.ts
- amend the v35 comment to mention the 10 structural pairs it now also stamps

Still mutation-checked: dropping `FROM Function TO File` now fails both the
integration sweep and the unit pin with exactly Function|File. 89 tests green.

* fix(schema): generate the attachment pair surface and close four analyze aborts

Review of the generated scope-bridge cross product found four `analyze`
hard-aborts still live at head, each reproduced end-to-end on the default
user path (`analyze --index-only --skip-git`):

  Method→Annotation   Spring `@Bean` + `@ConditionalOnMissingBean` (Java + Kotlin)
  Method→File         Vue Options-API `methods:` handler bound to a child event
  Namespace→Record    COBOL `DECLARATIVES` / `USE AFTER STANDARD ERROR ON <file>`
  Class→Tool          `@mcp.tool()` applied to a class

All four are pre-existing on main, and both existing guards were structurally
blind to them: the unit guard derives from LINKABLE_LABELS ∪ CALL_TARGET_TYPES
(none of Annotation/Tool/Record/File-as-target is a member) and the corpus
guard ran three fixtures that exercise none of these emitters. All 16 tests
passed while all four crashes were live.

The PR's model — "bridge endpoint × structural endpoint" — does not fit:
Namespace→Record is structural on both sides. The property that does hold is
that the ANCHOR is a lookup result, not a literal at the emit site, so the
emitter cannot constrain its label. That gives a second closed-form rule:

  DEFINITION_ANCHOR_LABELS × ATTACHMENT_TARGET_LABELS

DEFINITION_ANCHOR_LABELS is derived from NODE_TABLES by subtraction, so a new
node table joins automatically. 332 → 450 declared pairs.

Sized against a committed harness (gitnexus/bench/schema-pairs), real
@ladybugdb/core, identical data: 450 costs 0.93–1.05× of 332 on untyped-endpoint
anchored queries — inside noise — versus 1.22–1.43× at 641 and 2.03–2.34× at
1024. The harness reproduces the known #2792 cliff, which is what makes the 450
figure trustworthy.

Also in this change:

- Delete the 161 hand-declared pairs the rules already generate (233 → 72).
  The declared set is byte-identical at 450; those lines were load-bearing
  shadow, because the generator suppresses anything already declared
  structurally, so narrowing a rule later would silently keep pairs alive.
  A new guard fails CI if a hand-declared pair is ever re-added inside a rule.
- Import LINKABLE_LABELS / CALL_TARGET_TYPES instead of hand-copying them.
  The twins' stated justification ("the ingestion layer must not be imported
  here") is false: csv-generator.ts and lbug-adapter.ts, siblings in the same
  directory, already do, and no rule in AGENTS.md / ARCHITECTURE.md /
  CONTRIBUTING.md / GUARDRAILS.md states otherwise.
- Resolve `resolveStreamGraphEmit` after the guards that rebind `options.force`,
  not at function entry. It gates on `force`, and every freshness guard runs
  ~360 lines later, so the v34→v35 bump would have pushed every existing index
  down the non-streamed emit path — losing the #2680 memory streaming added for
  the #2649 kernel-scale OOM, for exactly the population most likely to be
  memory-constrained.
- `UndeclaredRelationPairError` now carries the relationship type, both node ids
  and the source file, with a matching CLI branch. The old message named only
  the abstract label pair, which a user could not act on. Found through the
  cause chain, since pipeline-phases/runner.ts rewraps every phase failure.
- Share one classifier (`relPairKeyFor`) across the router, both emit sinks and
  the corpus guard, which previously hand-mirrored the router's skip rule; one
  cause-chain walker in lib/utils.ts; one exported pair-matching regex.
- Corpus guard: four new fixtures reproducing the aborts, per-fixture sentinel
  pairs so a fixture that stops emitting fails loudly instead of passing
  vacuously on an empty graph.

The per-edge path stays allocation-free: the failure context is passed
positionally and the message is built only inside the throw.

* test(bench): re-baseline the COBOL capture fingerprint for the new fixture

`bench/scope-capture` globs `lang-resolution/cobol-*`, so the
`cobol-declaratives` fixture added in 81daf370e (to reproduce the
`Namespace→Record` analyze abort) joined that corpus and shifted the
fingerprint — 14 → 15 files.

Verified corpus-only, not a capture change: with that one fixture moved
aside the fingerprint is byte-identical to the prior baseline
(d45bb091…), and 81daf370e touches no COBOL capture code. The new value
reproduces CI's reported hash exactly. Scaling 0.677 < 1.5 budget.

`bench/scope-capture/measure.mjs --check` → PASS (15 languages).
