d541105340 fix(workflow-bench): repair the harness defects the verbose proposer logs exposed
The first fully-logged skill-evolution run failed for five deterministic
reasons that had nothing to do with the candidate under test. Each is fixed
at the layer that actually owns the contract:

- Strict provider adapters materialize omitted optional string arguments as
  "". The MCP alias normalizer now treats a blank optional alias as absent
  (a blank REQUIRED target is still rejected), and a trusted PreToolUse hook
  strips blank strings before Read/GitNexus tool calls.
- MCP semantic errors rode home in a successful envelope and logged as
  result=ok. SessionProgress now inspects the payload and reports them as
  semantic-error.
- Claude Code's nested sandbox overlays absent root dotfiles with device
  nodes, which the provenance snapshot read as unauthorized workspace
  changes. Those names are excluded at the workspace root and hidden from
  git via an immutable excludes file.
- The proposer could not read /evidence from Bash (missing allowRead entry)
  and had no offline gitnexus runner, so it fell back to npx and hit the
  network. Both are now mounted; ripgrep is installed in CI.
- selected-rows.json advertised host artifact names that do not exist in the
  mount. Rows now name their staged patch_file/transcript_files, the prompt
  describes the real layout, and oversized bundles compact artifacts before
  dropping evidence rows so no row is silently lost.

Also replaces two benchmark scenarios that main already satisfies
(trivial-version-alias, inv-bug-pdg-note) with non-vacuous ones, verified to
fail against a pristine checkout.

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

* 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.

fix(watch): await a watcher re-arm barrier so gitignore reloads cannot drop events (#3159)
* Increase CI timeout budget for flaky watch-filesystem test

* test(watch): include elapsed budget in waitFor timeout errors (#3156)

Make CI flake timeouts self-describing without raising the 90s ceiling, and cite the mcp/server-startup 15s/5s convention in the helper comment.

* fix(watch): await a watcher re-arm barrier after an ignore-rule reload

An ignore-rule reload re-armed the watcher with `watcher.add(repoPath)`,
which returns before the rescan it starts has finished and offers no signal
for that completion. A file the reload had just unignored was therefore still
unregistered when the call returned, and since `ignoreInitial` suppresses the
`add` that the in-flight rescan would emit, an immediate rewrite of that file
was dropped permanently. A standalone reproduction missed the rewrite 40/40
times on both chokidar 4.0.3 and 5.0.0.

Re-arm by arming a replacement watcher and awaiting its `ready` instead, which
is the only completion signal chokidar exposes (`ready` never fires twice on
one instance). The re-arm runs before the refresh, so a write that lands while
the replacement arms is still read by that refresh; the outgoing instance keeps
reporting until the swap, so no event window is dropped; and a replacement that
fails to arm leaves the working instance in place for the queue to retry. The
transient-watcher-error path now requests the same awaited re-arm rather than
re-arming inline ahead of its catch-up refresh.

This replaces the CI timeout increase from #3156, which treated the symptom:
the test was not slow, it was waiting for an event that never came.

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

* refactor(watch): drop restating comments and duplicated waitFor state

The re-arm error now uses the same cause-wrapping shape as ignore-control
reload, and the instant-rewrite test waits for both paths in one poll.

feat(ingestion): mint Destination nodes from AsyncAPI 3.x documents (#3140)
* feat(ingestion): read AsyncAPI 3.x documents into broker addresses

Adds a format-driven reader that turns the `operations[]` entries of an
AsyncAPI 3.x document into (broker, address, direction) triples, plus the
protocol-to-broker map behind it. Nothing consumes it yet.

The reader lives outside `frameworks/spring/` on purpose, like
`destination-key.ts` and for the same reason: an AsyncAPI document is a
published artifact emitted by generators across several language toolchains
and written by hand as often as generated. The entry criterion is therefore
the document format -- a root `asyncapi` key -- and never the generator.

AsyncAPI 2.x is refused under its own countable reason rather than mapped.
Its `publish`/`subscribe` are inverted relative to 3.x `send`/`receive`, so
a naive mapping reverses every direction in the async graph while leaving it
connected: nothing fails, the arrows simply point the wrong way. A silent
skip would be indistinguishable from "this service publishes no document",
which is the one thing the refusal count has to be able to tell us.

The broker is read twice over -- from the operation's bindings and from its
channel's server protocol -- and the two readings must agree. A destination
keyed on the wrong broker joins a stranger, and with the document
contradicting itself there is no way to tell which reading is right, so the
operation is refused rather than decided by a coin flip.

An unmapped protocol passes through as its own literal instead of being
dropped, because `destinationNodeKey` takes a plain string precisely so a
non-Spring caller can attest to a broker Spring has no member for.

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

* feat(cli): add --asyncapi-spec, an explicit path to AsyncAPI documents

Threads an `asyncApiSpecPath` option from the CLI, the server analyze
endpoint, and the programmatic entry through to `PipelineOptions`. Nothing
reads it yet; the reader added in the previous commit is still unwired.

Shaped deliberately after `springActuatorPath`, the existing option for an
out-of-band artifact: an explicit local path, accepting a directory or a
single file, resolved against the repository root so a committed
`docs/asyncapi` and an absolute cache populated by something else are both
natural, and `undefined` keeping the feature entirely off. Mirroring that
option rather than inventing a mechanism is what lets a downstream consumer
point the reader at documents fetched out of band without patching a file
here.

`analyze --watch` REJECTS the flag, exactly as it rejects --spring-actuator.
The watcher reacts to source changes and nothing watches a document
directory, so honouring it there would read the documents once and then
serve a stale answer for the rest of the session -- worse than refusing,
because it looks like it worked.

Additive only: 49 inserted lines, no deletions and no modified lines. Every
new interface member is optional and every forward is an object-literal
spread of an undefined value, so with the option unset the analyzer takes
byte-identical paths.

* feat(ingestion): mint Destination nodes from AsyncAPI documents

Wires the reader into the destinations phase. With `--asyncapi-spec` set,
every `send` operation emits PUBLISHES_TO and every `receive` emits
CONSUMES_FROM against the ordinary resolved `Destination` node -- same key,
same `address` property -- so a document and a source site that name one
address on one broker land on ONE node and the two halves of a conversation
meet. Verified end to end: an address named only in a document is minted
with the right broker and direction, and an address a source site already
resolved stays a single node with its own `literal` provenance while the
same address on a different broker stays separate.

This claims only what a document states -- that the service talks to that
address, on that broker, in that direction -- and never which method does
it. The addresses in one document partition by (broker, action) into buckets
that usually hold more than one operation, so any assignment past a bucket
of size one is a heuristic, and a wrong one attaches a real address to the
wrong handler: a false connection wearing the clothes of a resolved one. The
edge therefore starts at the document, not at a callable. That is weaker
than a source-derived edge and worth having anyway, because it is available
where the source supplies nothing at all -- a programmatically registered
listener, a broker with no patterns here, a language whose messaging idiom
nobody has taught this codebase yet.

Documents are read even when the source pass found no messaging, which is
why the early return had to move: a repository whose brokers are invisible
to the patterns is precisely the case a published document covers, and an
early return keyed on source sites skipped the documents exactly there.

Their counters are kept in their own block rather than folded into the
existing ones. `refusalsByReason` is the denominator of the SOURCE
unresolved fraction, and a mistyped specification directory must not be able
to make the source look worse than it is. The block is absent -- not zeroed
-- when no path was configured, so "not asked for" stays distinguishable
from "asked for and found nothing"; those need different answers from an
operator and one zero cannot say which happened.

The direction assertion is the one that matters and it is pinned by type,
not by existence: inverting the mapping in the source tree fails exactly one
test, because every other assertion passes identically under both readings.

* docs: document --asyncapi-spec and why step 4 of the cascade stays empty

Adds the flag to both READMEs and to the three byte-identical copies of the
CLI skill, which a sync test pins together.

Also rewrites the note on the `specification` seam in the address cascade.
It said "nothing supplies it today", which was true and is now misleading:
a reader exists, and the hook is still unsupplied because of a decision
rather than for want of one.

A document names addresses; it does not name the method that uses one. To
hand an address to a particular candidate something must choose which of the
document's operations belongs to it, and the only division both sides agree
on -- (broker, action) -- leaves buckets that usually hold more than one
operation. On a real generated document exactly one bucket of four was
unambiguous. Every assignment past a bucket of size one is a heuristic, and
a wrong one puts a REAL address on a joining node under the wrong site: a
false connection wearing the clothes of a resolved one, which is the outcome
the keying rule exists to prevent.

The note also records the two things that would change that and are not
heuristics -- a document carrying the implementing symbol, or a
configuration source answering the `${key}` the candidate already recorded
-- and that the second wants its own resolver, since what it needs is the
placeholder key rather than the candidate.

* fix(ingestion): refuse the document shapes that would forge a join

Four ways a conformant AsyncAPI document could mint a Destination that
connects two services which have said nothing about each other. Every one is
reachable from ordinary 3.x vocabulary, not from malformed input, and each is
now a countable refusal.

A PARAMETERIZED ADDRESS is a pattern, not a place. Two services that publish
`{env}.orders` share a template; one deploys with env=prod and the other with
env=staging, and keying on the template text merges them into a single node
with a publisher on one side and a subscriber on the other. This is the
document-side twin of `overridable-config-default`, which argues the same
thing about `${key:default}` in source. A channel declaring `parameters` is
the specification's own statement that its address is a template, so the
detector is a reading rather than a guess; the `{` test catches generators
that template without declaring.

ANY BINDINGS KEY WAS TAKEN AS A PROTOCOL. AsyncAPI allows `bindings` to be a
Reference Object, so the map's own key can be `$ref` -- and passed through,
that becomes half of a join key carrying no broker information at all. Two
services that both reference shared bindings and both name `orders` then land
on one node, defeating the broker-in-key rule that keeps `kafka orders` and
`rabbit orders` apart. A broker must now be spelled like a protocol name.

A BROKER CONTAINING A SPACE COLLIDES, because the node key joins with one:
("kafka orders", "x") and ("kafka", "orders x") are the same key. That was
latent while every broker came from Spring's closed union. This module is the
first caller to feed the shared helper text that a document wrote, which is
exactly the condition under which it stops being latent, so it is closed here
-- at the producer -- rather than by changing an encoding that `routeNodeKey`
shares.

THE ADDRESS WAS TRIMMED, while the source cascade keeps an address exactly as
written so `" orders "` stays its own node. Two producers of one key held
opposite whitespace policies and the document side erred toward joining.

Also: fold the transport-security protocol variants (`kafka-secure`,
`secure-mqtt`, `wss`, `stomps`, `https`) onto their base protocol. The
`amqp`->`rabbit` argument already in this file demands it -- AsyncAPI's server
vocabulary distinguishes them and its bindings vocabulary does not, so a
secured cluster's own document was being read as self-contradictory. Treat a
channel with no `servers` as available on all of the document's servers, which
is the specification's default and was costing every single-server document
its destinations. Bound the address and operation-id lengths, because
`generateId` concatenates rather than hashes, and bound total operations
across the run rather than only per document.

Read each file through ONE handle for both the size gate and the read, as
`actuator-runtime.ts` does and for the reason its comment gives (CodeQL
js/file-system-race): re-resolving the path lets a swapped file bypass the
cap, and the out-of-band cache this option reads is written by other tooling
by definition. Open it with O_NONBLOCK: the type check that rejects a FIFO is
unreachable without it, because opening a FIFO for reading blocks in open(2)
until a writer appears -- found by writing the test first and watching it time
out rather than fail.

Count symlinked entries and walk truncation instead of dropping them in
silence. A symlinked cache and a wrong path were producing identical results.

* fix(analyze): rebuild when documents are configured, and report what was read

An AsyncAPI document is external to git freshness in exactly the way an
Actuator snapshot is: replacing one moves no commit and dirties no file. The
option's own README paragraph advertises an absolute cache written by other
tooling, and on the second run of that workflow the already-up-to-date fast
path fired, no document was ever opened, and the previous run's addresses were
served as current. Measured, not reasoned: editing a document and re-running
printed "Already up to date" and left the old address in the graph; with this
change the same probe re-reads and the new address replaces it.

So an enabled run forces a rebuild and dropping the option forces one more, to
clear document-derived evidence -- the treatment `springActuatorPath` already
gets, for the same reason. Only the FLAG is recorded in index metadata, not
the path: Actuator retains its inputs so future scans keep excluding them,
whereas a committed document is deliberately NOT excluded (it wants its real
`File` node), so there is nothing to retain and recording the path would put
an operator's directory layout into metadata for no consumer.

That also settles a defect it would have been tempting to patch separately. A
synthetic `File` node for an out-of-tree document carries a path that is in no
write set and is not covered by `isGraphWideNode`, so an incremental writeback
dropped the node while keeping its edges -- which then COPY against a row that
was never written, and fail into an IGNORE_ERRORS retry that reports success.
A forced rebuild has no incremental subgraph to get that wrong.

Distinguish the two meanings of `resolution: 'specification'`. That value
belongs to the address cascade and means a CODE candidate was resolved through
the step-4 hook; a node minted from a document has no code site and now says
`asyncapi-document`. Reusing one string would leave a query that groups by
provenance unable to separate an address a document states from one a document
was used to resolve, and only the second is a claim about source.

Report what was read. The stats block was justified on the grounds that an
operator must be able to tell a mistyped directory from a repository with no
documents -- and nothing surfaced it, so the justification was aspirational. A
configured path that yields nothing, or a walk that hit a bound, now warns
unconditionally, as `spring-auto-configuration.ts` does for the same class of
input. The phase summary carries the refusal breakdown rather than only the
totals, because the unresolved fraction is the number this work is judged on
and a bare count says how big the gap is without saying what would close it.

Tests for the three wiring lines that were individually deletable with a green
suite, following the templates already in the repository: a row in the
`--watch` rejection table, the CLI-threading assertion beside the Actuator
one, and the shipped-skill fragment that pins the flag in all three copies.
Also pin `filePath: ''` on a spec-minted destination -- the half of the keying
rule that stops a shared node becoming collateral damage of one document's
next change -- and the in-repo `File` branch, which was dead-code-able.

* fix(ingestion): close the join-forging paths a second review round found

The `$ref` exclusion added last round fixed one instance of a class and left
the class open. A `bindings` map key of `x-scs-function` -- an ordinary
Specification Extension, which generators emit -- still became the broker, so
two unrelated services carrying one vendor annotation and one address landed
on ONE node whose broker half said nothing about any broker. And
`{ kafka: {}, x-internal: {} }` read as two brokers, losing a conformant
document and reporting it as self-contradictory, which also made any document
author a one-line saboteur of their own cross-service links.

So the two readers are now separate functions with opposite defaults, and the
header says why they must be. `servers[].protocol` is a FIELD DECLARED to hold
a protocol: an unrecognized value there is the document's own claim and passes
through, because refusing it would lose a destination the document states
plainly. A `bindings` MAP KEY is not that -- the specification puts `$ref` and
`x-` in the same namespace -- so a non-protocol key is the EXPECTED case and
only AsyncAPI's binding vocabulary may answer. The syntactic test that was
applied to both was the right rule for one of them.

The walk fix from last round introduced something worse than it reported. A
shared abort flag meant depth exhaustion in ONE branch terminated the whole
traversal, so ten good documents beside a twelve-deep unrelated subtree were
kept or lost depending on whether that subtree sorted before or after them.
Truncation and budget-exhaustion are now separate: depth returns from its own
branch, and only a genuinely global bound stops the walk.

Rewriting `protocol.ts` dropped the whitespace check from the server-protocol
path and made the node-key collision reachable again. The test written for
that collision last round caught it within the minute; the comment now records
that it was learned twice.

Everything else measured this round:

- The broker is the THIRD string that reaches a graph identifier, and it was
  unbounded while the header claimed there were two. A one-megabyte protocol in
  a document satisfying every other cap was measured producing a gigabyte of
  resident identifier strings, because `generateId` concatenates rather than
  hashes and the phase mints one id per node and per edge.
- The run-wide operation budget counted ACCEPTED operations, reproducing at the
  run level the exact defect the per-document cap was corrected for last round:
  a run whose every operation is refused never decrements it. Both now count
  operations EXAMINED, and `operation-cap` sets `truncated` -- it is a bound
  that stopped the operation count, which is what that flag is documented to
  mean.
- The channel-inherits-all-servers rule ran per operation. Hoisted: it depends
  only on the servers.
- A subdirectory that cannot be listed is counted rather than dropped, so a
  mixed-permission cache cannot report a clean, complete read.
- The read LOOPS, like the Actuator reader this claims to follow. A single read
  was never short across seven hundred probes on APFS, but POSIX permits it and
  FUSE mounts with `direct_io` -- the deployment this option targets -- return
  short counts. A document truncated at a line boundary still parses, so the
  failure is silent: operations vanish with `refusals: {}`.
- `parameters: {}` no longer refuses a literal address; an empty container
  states nothing and generators emit them.
- A channel that is itself a Reference Object gets its own reason instead of
  `no-address`, which was telling operators their documents omit addresses when
  the reader simply stops one hop short.
- A multi-protocol document resolves from its operation's own bindings; only
  when those are silent does an inherited multi-protocol server set refuse, and
  under `ambiguous-server-default` rather than a reason that says the document
  contradicts itself. It does not.
- HTTP and WebSocket are refused for destination minting. For a broker the
  topic is the namespace; for HTTP the host is, so keying on the path alone
  would make every service exposing `/events` one node. A `Route` already
  models an HTTP endpoint, with its method in the key.
- The sniff window is a parse gate, not a read gate, and four kilobytes refused
  a good document behind a licence header.

* test(ingestion): pin the wiring and the reporting that were deletable

Three lines could be deleted with the whole suite green, and each of them
makes the feature partly or wholly inert: the forward from `run-analyze` into
`PipelineOptions`, the forced rebuild while documents are configured, and the
cleanup rebuild when the option is dropped. None is visible one layer up,
where the CLI test asserts on a mock's arguments.

One integration test closes all three. It drives the real `runFullAnalysis`
against a real repository and asserts, in order: the enabled run does not take
the up-to-date fast path and logs the rebuild; the destination reaches the
graph, which only happens if the option is forwarded; a document edited with
the tree clean and the commit unchanged is re-read; dropping the option
rebuilds once and removes the document-derived evidence; and the run after
that is up to date again -- the "rebuilds once" half, which rests on the
metadata being written as a fresh literal rather than merged, and which
nothing pinned.

The document lives OUTSIDE the repository on purpose. That is the workflow the
option is documented for, and it is the only one where the hazard exists:
editing a tracked file dirties the tree and forces a rebuild anyway, so an
in-repo fixture would pass with the freshness fix reverted. Verified by
reverting both: deleting the forward fails on the empty destination list,
deleting the forced rebuild fails on the missing log line.

Also pinned, each because deleting the code it covers left the suite green:
the `parameters` half of the templated-address refusal (its old test supplied
a braced address too, so the `{` half alone satisfied it); the phase actually
forwarding `symlinksSkipped`; the unconditional warning, whose whole argument
is that a tally nobody can see is not a tally -- captured through the
repository's own `_captureLogger`; a `.yml` document; a character device,
which is the case the `isFile` check exists for and which the FIFO test does
not reach; and the bound that stops a walk.

Reject an empty `--asyncapi-spec` at the CLI. It resolved to the repository
root and walked the whole tree, defeating this module's own rule that there is
no glob-based auto-discovery -- and the HTTP entry point already rejected the
identical value. Two doors onto one option must not hold different rules.

Surface the flag in the MCP context resource beside `spring_actuator`. It
matters more there than for its neighbour: Actuator annotates nodes the source
pass already found, while document reading mints destinations and edges with
no code site, and nothing said where they came from.

Log the configured path relative to the repository. The same change refuses to
persist that path to index metadata because it would record an operator's
directory layout; holding that rule for metadata and not for logs was holding
it in one place.

Both test files now clean up their temporary directories.

* style(ingestion): apply the repository's prettier contract

`quality / format` runs `npx prettier --check .`, and three files added by this
branch were not formatted to it. No behaviour changes: the reader's line
breaks and two test literals move, nothing else.

* test(ingestion): release the mini-repo handle the document test allocated

`setupMiniRepo` documents that the caller owns cleanup, and every other test
in this file calls `repo.cleanup()` in its `finally`. The AsyncAPI document
test removed only the document directory, so each run left a temporary
repository behind.

The two owners are separate on purpose: the document directory is a SIBLING of
the repository, placed outside the working tree so that editing it cannot
dirty the tree and force a rebuild on its own. The repo's cleanup therefore
does not reach it, and both calls belong in the same block.

* fix(ingestion): stop partial server evidence from reading as unanimous

Six review findings, every one a way this reader could name a broker the
document does not name. They share a shape: something is DROPPED rather than
refused, the remaining evidence agrees with itself, and an operation is
attributed with confidence to a broker its document never settled on. A wrong
broker is half a join key, so it does not produce a missing edge -- it produces
an edge to a stranger, reported as a fact.

CAPPED SERVER MAPS. A channel with no `servers` inherits all of them, and that
map is capped at 1,000. A document whose first thousand servers are Kafka and
whose thousand-and-first is JMS read as unanimously Kafka, because unanimity
was tested on the slice. Counted `server-cap` and set `truncated`, but neither
stopped the attribution. The inherited path now refuses under
`capped-server-default` -- checked BEFORE agreement, since a subset agrees with
itself for free.

ROOT SERVER REFERENCE OBJECTS. The Servers Object patterned field is
`Server Object | Reference Object`, so `{ $ref: '#/components/servers/prod' }`
is conformant. Reading `protocol` off the raw value dropped every one: an
all-reference document had no protocol at all, and -- worse -- a MIXED set lost
its disagreeing half and became unanimous. One hop is now followed, through
`#/servers` and `#/components/servers`; anything else is refused under
`unresolved-server-reference` rather than skipped.

CHANNEL BINDINGS. Only the operation's bindings were read. A conformant channel
carrying `bindings: { kafka: {} }` with no operation binding was dropped as
`protocol-unknown` while the document said plainly which broker it meant, and a
disagreement between the two levels was invisible. Both are read; a conflict is
`protocol-disagreement`.

EMPTY `servers`. "If `servers` is absent or empty, this channel MUST be
available on all the servers defined in the Servers Object" -- one sentence,
both cases. A zero-iteration loop returned `explicit: true`, which blocked the
inherited fallback and dropped valid operations.

POINTER DECODING ORDER. RFC 6901 percent-decodes the fragment BEFORE splitting
on `/`. The raw token was tested for a separator first, so `#/channels/orders%2Fv1`
passed a check it should have failed and then decoded into two segments -- a
pointer addressing `channels.orders.v1` was read as a channel named `orders/v1`,
inventing a channel the document never declared. A malformed escape is now
refused rather than resolved against its undecoded text. `~1` still resolves; it
is the pointer's own escape and belongs after segmentation.

THE SNIFF WINDOW. A fixed window decides by where the root key sits rather than
whether it is there, so every window is a false negative waiting for a longer
preamble -- 4 KiB was replaced by 64 KiB for that reason and inherited the same
defect. The whole text is scanned; it is already bounded and already in memory,
and the gate exists to skip the PARSE, which is the expensive half. A leading
UTF-8 BOM is stripped before both sniff and parse.

Twelve of the fourteen new tests were run against the unfixed reader and all
twelve failed; the other two are controls that must pass either way.

feat(route): resolve vendor-derived Spring mapping annotations by suffix (#2883)
* feat(route): resolve vendor-derived Spring mapping annotations by suffix

Frameworks commonly wrap Spring's built-in annotations with company-specific
variants (e.g. Winning Health's @WinPostMapping wraps @PostMapping). The
annotation definition lives in a binary JAR — not in source — so the
meta-annotation cannot be read statically.

Add resolveSpringAnnotationAlias(): resolves custom annotations by naming
suffix (WinPostMapping → PostMapping → POST). This matches the universal
Java convention of naming derived annotations with the base name as a suffix.
Works for any vendor prefix, not just one company.

The fix is in springAnnotationHttpMethods() (spring-shared.ts), which both
the ingestion extractor (spring.ts) and the group extractor (java.ts) call.
A single-function change propagates to both layers automatically.

Zero configuration: no .gitnexusrc, no annotation allowlist. If an annotation
name ends with a known Spring mapping suffix, it inherits that annotation's
HTTP semantics. False-positive risk is negligible.

Tests: 16 new unit tests covering resolveSpringAnnotationAlias directly,
springAnnotationHttpMethods with aliased annotations, end-to-end
extractSpringRoutes with vendor annotations, and ingestion/group parity.

Existing route tests (260) continue to pass.

* fix(route): address review findings — class-level aliases, registered prefixes

P1: class-level @WinRequestMapping now gets the same prefix/constraint
semantics as @RequestMapping — all five class-level exact-match sites
(spring.ts phase-1 collect, typeRequestMethods, typeClassPrefixes; group
http-patterns java.ts typeRequestMethods + type-level branch) route
through the new shared isClassLevelMappingAnnotation predicate, and the
hard-coded 'RequestMapping' argument in springAnnotationHttpMethods calls
is replaced with the actual annotation name so alias resolution applies.
P2: suffix-only alias matching accepted unrelated annotations
(@AuditPostMapping emitted a phantom POST /audit). Alias resolution now
requires a REGISTERED vendor prefix — 'Win' by default, extendable via
GITNEXUS_SPRING_VENDOR_PREFIXES=Win,Acme without a rebuild.
Tests: negative e2e for the unregistered-suffix phantom route, vendor
class-prefix parity e2e, predicate unit matrix, env-registration test.

feat(node): wrapped-client HTTP consumers + leading-prefix template stripping (#3111)
* feat(http-patterns): Patch 8 - extract enterprise wrapped-client HTTP consumers

Recognize the enterprise axios-wrapper call shape X.request({ url, method })
(e.g. httpClient.request from @winex-plugin/win-request) as a consumer
contract source, and strip the leading gateway/service-prefix template
variable so consumer paths align with backend provider routes.

Effect on sr-next group: 1740 contracts / 0 cross-links ->
3540 contracts / 883 exact cross-links (14 frontend repos <-> backend/opt).

Not submitted upstream yet; see CUSTOM_PATCHES.md Patch 8 for details.

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

* feat(node): wrapped-client HTTP consumers + leading-prefix template stripping

Consumer extraction for enterprise axios-wrapped clients:
- X.request({ url, method }) member form (httpClient.request from
  win-request and friends): any .request(options) call with url/method|type
  string props; the url template literal is split on ${...} spans and the
  longest /-leading literal segment is kept.
- Leading ${...} gateway/service-prefix variables are stripped as
  consumer-path normalization semantics in normalizeHttpPath
  (stripLeadingTemplatePrefix): `${client}/api/v1/x` → /api/v1/x for
  fetch/axios/wrapped shapes alike. Mid/tail interpolations still round-trip
  through {param}; a stripped remainder not starting with / is dropped
  (same rejection static relative urls get at scan time).
- %7B/%7D unescaping for absolute-URL branches.

On our 16-repo frontend monorepo this took group sync from 1740
contracts / 0 cross-links to 5111 / 2097 (exact links, 16/16 repos linked).

* fix(route): preserve upstream symbol-resolution machinery; strip only

Rebasing correction: an earlier iteration of this change simplified the
symbol probing to a bare line-1 offset and dropped the exact-module match,
which mis-attributed data-table handlers to decoy same-name symbols
(6 data-route-table regressions). Restore the upstream probing
(toZeroBasedLine + exact-module resolution) wholesale; the deltas this
change actually needs are the pure ones: stripLeadingTemplatePrefix,
normalizeConsumerPath returning null for un-reducible urls (callers
drop), and the %7B/%7D brace restoration in the absolute-URL branch.

The watch timers are assigned exactly once, so prefer-const rejected the

safe and drops the now-dead undefined guards.

Remaining files are formatting only.

* fix(watch): make lock identity absolute and stop three fail-open paths

Lock owner identity was rendered by `ps -o lstart=` through localtime and the
active locale, so the same live process produced a different string under a
different TZ. A mismatch reads as PID reuse, so one daemon could reclaim a
mutex another still held. Pin TZ=UTC and LC_ALL=C.

The owner record also carried no hostname, so a holder on another machine was
judged by this kernel's view of its PID — always "stale" — and its lock stolen
whenever GITNEXUS_HOME is a shared volume. Record and compare the hostname, as
the index lock already does.

Ownership verification threw unconditionally on win32, which is reached once
per project per tick, so watch reported `running` and then failed every repo
forever. POSIX uid/mode cannot be checked there; skip those two assertions and
keep the dangerous-root, symlink, containment and internal-root guards.

Also: quarantine sweep now refuses a symlinked root instead of deleting
through it; an unreadable state file propagates instead of being rewritten as
empty state, which used to erase every repo's analyzed commit and failure
count; a failed staging cleanup no longer strands a published lock with no
release handle; and the concurrency runner settles every worker before
surfacing a failure so cancellation cannot orphan a live analyze fork.

* fix(watch): land the deferred review findings

Six findings that were deferred from the review backlog, plus the docs they
change.

Worker heap: admission allowed `floor(availableMemoryGB / 2)` slots while every
fork was handed the whole machine's heap cap, so the budget meant nothing as
soon as an operator raised max_concurrency. Divide the cap by the repos
actually analyzed in parallel. The default single-project path is unchanged.

Registration: the parent registered without a branch, so it always took the
primary/flat arm and relabelled a pinned branch entry on the branch-fallback
path. Reproduce the worker's own resolveBranchPlacement decision instead.

Cancellation: requestCancellation cleared the only timer and settled nothing,
so a worker wedged past its safe point left the promise pending forever,
wedging activeRun and hanging `watch stop`. Add a 5s grace after which the
parent stops waiting and releases the IPC channel's hold on its event loop.
The child is still never killed — it may be inside native work.

overwrite_local_changes: `checkout --force` rewrites tracked files only, so
untracked sources survived and were indexed as if they came from the remote.
`git clean -fd -e /.gitnexus` after checkout; no -x/-X, so ignored paths and
GitNexus's own storage survive.

Quarantine: age alone never bounds a repo that fails every tick, since each
partial clone is younger than the retention window. Keep the five newest per
repo.

Validation: repo_git_timeout is now bounded by the lesser of an hour and the
sync interval, which is also the guard for the bare-number-means-seconds slip
(`600000` meant ~7 days and cleared the timer ceiling). And the remote URL's
final segment is validated at config load rather than failing once per tick
inside the sync loop.

* fix(watch): release an errored worker, and stop rejecting dotted repo names

Three findings from the latest review pass.

The 'error' handler settles immediately rather than waiting out the grace, so
cleanup() clears the grace timer that would otherwise have released the child.
An errored IPC channel does not mean the worker stopped, so release it on that
path too — still no kill.

The traversal guard tested the raw path for '..', which also rejected an
ordinary name like owner/foo..bar that the repository-name rule accepts.
Traversal is a whole segment, so test segments.

The heap-cap test left two runs and their real timers pending; it now stubs
timers and settles both promises. Registration coverage now pins the branch
slot rather than leaving it implicit.

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

* fix(watch): validate namespace segments and pin the stopped process identity

Replacing the raw-string `..` test with a per-segment one dropped a guard: a
segment like `..\..\outside` is not literally `..`, so it passed, and those
segments build the clone path — on Windows the backslashes are separators.
Hold every namespace segment to the same charset as the repo name, which keeps
a separator out of a segment while still allowing an ordinary `foo..bar`. The
final segment keeps its own check so a bad repo name keeps its own message.

The stop wait polled liveness by pid alone, so a pid reused mid-wait would
have it wait on an unrelated process and then report the watch stopped. Compare
the process start time recorded for the owner, which also returns sooner.

Registration now omits `branch` for a primary index instead of passing it as
undefined, so that call keeps the shape it had before this branch.

fix(mcp): honor includeTests for C#, Java, Swift and PHP test paths (#2866)
* fix(mcp): honor includeTests for C#, Java, Swift and PHP test paths

Test-file classification had two hand-maintained implementations that had drifted:

  core/ingestion/entry-point-scoring.ts  isTestFile      — excludes tests from
                                                           process entry points
  mcp/local/local-backend.ts             isTestFilePath  — backs `includeTests`
                                                           on impact/trace/context

The MCP copy recognized no C#, Java or Swift test convention and neither PHP
form, so `includeTests: false` silently failed to filter them — a C# project's
`*.Tests/` and a Maven project's `src/test/` landed in blast-radius output as
though they were production callers. The scoring copy missed `/fixtures/` and
`/conftest.`, so those could be selected as process entry points.

Both now delegate to one predicate carrying the union of the two pattern sets.
Public names are unchanged, so importers are unaffected.

The duplication was not gratuitous: `entry-point-scoring.ts` imports the
language-provider registry, and #2802 deliberately cut that closure out of MCP
server startup — importing it from `local-backend.ts` would put it back. The
shared predicate therefore lives in its own module with NO imports, and a test
asserts it declares none, so the startup cost cannot be reintroduced by a future
import added there.

19 new tests: the previously-missed paths per language, nullish and
Windows-separator handling, production paths that must NOT match, and a
cross-check that both public names agree on every case — the regression guard for
the drift itself.

Behavior-neutral on a Python/Go/TypeScript repository (204,336 nodes / 299,580
edges / 813 flows before and after), since the newly-recognized patterns are
languages it does not contain. `npx tsc --noEmit` clean; 728 tests pass across
the entry-point, process, impact and test-file suites.

* Address PR review feedback (#2866)

fix(routes): connect decorator routes to their handler function (#2865)
* fix(routes): connect decorator routes to their handler function

A Route node's only relationship was HANDLES_ROUTE from its FILE. The graph knew
a route existed and which file declared it, but not which function implemented
it. Two consequences on a 12.4k-file repository with 162 FastAPI routes:

  - Every decorated handler was indistinguishable from dead code. Its sole edge
    was DEFINES, so a reachability query reported it unreferenced even though the
    framework invokes it on every request.
  - `route_map` / `api_impact` could only answer at file granularity, and
    `processes.ts` routed every route through its `routesWithoutHandlerByFile`
    fallback instead of keying by handler.

Two halves of one gap, both already designed for and neither wired:

1. `ExtractedDecoratorRoute.handlerName` is documented as "captured at extraction
   where the decorated definition node is in hand", and `resolveRouteHandlerSymbols`
   already consumes it to stamp `handlerSymbolId`. Only the Spring extractor ever
   set it, so for every decorator-routed framework — FastAPI, Flask, NestJS — it
   arrived undefined and 0 of 162 routes carried a handler. A route decorator's
   parent IS the decorated definition, so the name is in hand: add
   `decoratedDefinitionName` and thread it through. It climbs consecutive
   decorators so stacked forms (`@router.get(...)` over `@requires_auth`) resolve,
   caps the climb so a malformed tree cannot loop, and returns undefined rather
   than guessing — the routes phase already treats a missing name as
   "fall back to file-level".

2. With a handler symbol resolved there is finally something to point an edge at.
   Emit a definition-level HANDLES_ROUTE alongside the file-level one. The sibling
   decorator overlay already does exactly this: `pipeline-phases/tools.ts` anchors
   HANDLES_TOOL on the definition the decorator sat on, not its file. Routes were
   the outlier.

Kept as one change because the edge is inert without the symbol — emitted from a
branch lacking part 1 it produces zero edges, since `handlerSymbolId` is empty.

Additive, and both existing consumers are unaffected:
`group/extractors/http-route-extractor.ts` types its query `(handlerFile:File)`;
`manifest-extractor.ts` matches an untyped `(handler)` but takes `LIMIT 1` ordered
by `handler.id`, and `File:…` sorts before `Function:…`, so its selected row is
unchanged.

Direction is Function → Route, matching how every other overlay attaches
(MEMBER_OF → Community, STEP_IN_PROCESS → Process, HANDLES_TOOL → Tool: the symbol
is the source). That also keeps it free of schema risk — `Function|Route` is
already declared by the ATTACHMENT rule in `lbug/schema.ts`
(`DEFINITION_ANCHOR_LABELS × ATTACHMENT_TARGET_LABELS`), which that file documents
as deliberate headroom for this case. Route → Function would have needed a new
hand-listed pair, and an undeclared pair aborts `analyze` outright — a failure
that file records having hit four separate times.

Verified on a FastAPI fixture (edges 9 → 11):
  api.py        (File)    -> GET /widgets, POST /widgets   [unchanged]
  list_widgets  (line 10) -> GET  /widgets                 [new]
  create_widget (line 15) -> POST /widgets                 [new]

On the 12.4k-file repository: 161 of 162 routes now resolve to their handler
function, up from 0. The single abstention is `uniqueSymbolId` correctly refusing
to guess where the name is not uniquely resolvable in its file.

`npx tsc --noEmit` clean; schema-pair coverage and route suites pass (196 tests).

* fix(routes): harden decorator handler attribution (#2865)

Keep definition-level route links correct across warm caches and malformed symbol lookups, and avoid per-route group-sync scans. Move Python AST ownership behind the language provider and add end-to-end regression coverage.

feat(ingestion): capture Spring handler annotation arguments and template publishes (#3128)
* feat(ingestion): capture Spring handler annotation arguments and template publishes

Non-HTTP handler recognition already resolves the annotation NAME through
imports, aliases, use-site targets and package visibility. What it never
captured is the annotation's ARGUMENTS, so the destination a listener binds to
was invisible: `@KafkaListener(topics = ...)` and `@RabbitListener(queues = ...)`
name it with different attributes, and a producer names it by position. The
publishing side was missing entirely, which left every messaging edge
one-directional by construction.

Consumer side: `SpringNonHttpHandlerAnnotationFact` gains an optional
`args?: readonly { name?: string; text: string }[]`. `name` is optional because
positional and named arguments are genuinely different shapes, not because it
is sometimes unknown.

Producer side: `KafkaTemplate.send`, `RabbitTemplate.convertAndSend`,
`JmsTemplate.convertAndSend` and `StreamBridge.send` for both languages.

Arguments are captured as SYNTAX, never as a resolved address. At capture time
imports are not final, a sibling file's constants do not exist yet and
configuration has not been read — the same reason annotation-name resolution
was deferred. Resolution belongs to a later phase; doing it here would be a
layering error that happens to work on simple inputs.

The parse cache schema moves 82 -> 83. Both new facts ride the existing
worker -> main side channel, which is replayed verbatim from
`ParsedFile.captureSideChannel`, so a warm v82 cache would skip the workers and
hand back annotation facts with no `args` and an empty producer list. Measured
on the fixture app: a warm all-cache-hit run (`usedWorkerPool=false`,
`reparsedFileCount=0`) reproduces 6 Java and 7 Kotlin producer facts from the
store alone — exactly the state a pre-change cache would have served as zero.

Tests cover both languages across literal, constant and configuration-key
destinations, and pin the PREVIOUS behaviour too: handlers captured before are
still captured, and shapes that must not produce a fact still do not.

* test(ingestion): cover the handler and template shapes capture left unpinned

Auditing the argument capture against its own definition of done turned up
three annotations and three templates that work but that nothing asserts, so a
regression in them would land silently.

Handler side: `@EventListener` and `@ServiceActivator` were only ever checked
for RECOGNITION, never for arguments, in either language, and Kotlin
`@RabbitListener` appeared in no argument test at all. Both annotations carry an
address just as `topics` and `queues` do — an event listener names it as a type
and an integration endpoint names it as a channel — so leaving them unpinned
left a third of the handler family covered by nothing.

Producer side: Kafka was the only template whose destination was written three
ways. Rabbit, JMS and the stream bridge each appeared with a single spelling, so
nothing said that a constant or a configuration-bound name produces a fact for
them too. The same fixtures pin the negative that `RabbitTemplate.send` and
`JmsTemplate.send` stay unrecognized, since only the method that belongs to the
template counts.

Each test asserts the previous behaviour alongside the new one: the handler is
still recognized and still named the same, and only then are its arguments
checked. A test that looked at arguments alone would keep passing if recognition
itself broke.

Verified against the parent commit that this is coverage, not repair: every
Java and Kotlin fixture in the suite produces a byte-identical capture side
channel on both revisions once arguments and producer facts are set aside.
Mutating `StreamBridge` out of the template table, and making Kotlin annotation
arguments return nothing, each fail the new tests.

* fix(ingestion): stop Spring capture from inventing arguments and receivers

Five defects in the capture-time Spring messaging facts, all of which put
data that is wrong — not data that is missing — into a durable store.

Facts built from recovered syntax. After a syntax error tree-sitter keeps
parsing by guessing boundaries, so the tree stays well formed while
describing text nobody wrote. An unterminated `kafkaTemplate.send(TOPIC,`
absorbed the next method's source and offered it as two more arguments;
`@KafkaListener(topics = "orders", groupId =` reported a `groupId` whose
value was an empty `{}` borrowed from the method body. Both now fail
closed: a producer call with an unparsed argument list yields no fact at
all, and an annotation with one reports no arguments. Neither carries a
state that could mean "published somewhere unreadable", so the choice was
between silence and a plausible lie.

Arguments were not normalized though the receiver beside them was. The
receiver already collapsed a wrapped chain to one spelling; the argument
kept its newlines and the ENCLOSING block's indentation, so the same
constant compared unequal to itself at two nesting depths, and again in a
CRLF checkout. Receiver and argument now share one normalizer.

That normalizer damaged multi-line literals. Its doc comment promised to
keep the rewrite away from nested string literals, and delivered that only
for single-line ones: a Java text block or Kotlin raw string whose newline
sat next to a dot lost the newline, changing the value. The normalizer is
now literal-aware, which makes the promise true for both.

The receiver name match accepted only one decoration. Matching the type
name as a suffix recognized `orderKafkaTemplate` and dropped
`kafkaTemplateDlq`, `kafkaTemplateV2`, `kafkaTemplate2`, `KAFKA_TEMPLATE`,
`kafka_template`, `streamBridge2`, `STREAM_BRIDGE`, and `rabbitTemplate1` —
including the `static final` constant spelling, which is exactly the shape
this capture exists to find. The name is now folded on `_`/`$` and matched
as a substring. The bare-identifier gate still runs first and is what keeps
`config.get("a.kafkaTemplate")`, `templates["k"]`, and `getTemplate()` out.

Ownership was attributed one level too deep. With no boundary types the
ancestor walk passed through a nested type body, so a publish in the field
initializer of a class declared inside a method was attributed to that
method, which may never run it. The identical construct at the top level of
a class already yielded no fact; a type body is now a boundary so the rule
reads the same at every depth, while a publish in a METHOD of a nested or
anonymous type is still attributed to that method.

* perf(ingestion): read Kotlin handler annotation arguments on evidence

Kotlin asked for annotation arguments unconditionally, for every annotated
function with any annotation, while Java made the same decision in two
passes and paid only for callables that carry a handler annotation.
Measured on 200 annotated NON-handler functions in one file, the Kotlin
side-channel payload went from 41069 bytes to 78797 — a doubling, crossing
the worker boundary and landing in the durable store, for data no consumer
reads today.

The reason Kotlin had no prefilter is real and is preserved: an import
alias (`EventListener as SpringEvent`) gives a handler annotation a local
name no list can contain, so discarding CALLABLES by simple name would lose
them before the post-import resolver runs. That argument covers capturing
the annotation; it does not cover reading its arguments, because the alias
is not a mystery at capture time. The import header states both the local
name and the FQN it stands for, so the existing relevance predicate can be
asked about the IMPORTED name and the answer carried back to the alias.

Kotlin now runs Java's two passes, with that alias set widening the first
one. Every annotated function still produces a fact with the same name and
use-site target as before — the non-handler payload is 41069 bytes again,
byte for byte what it cost before arguments existed — while handlers, and
handlers reached only through an alias, keep their arguments.

Also corrects two comments that described behavior the code did not have.
The Java capture claimed an economy Kotlin was not making; it now describes
both languages. The argument opt-in on both DI modules claimed it kept
argument text off the wire, but every DI fact already carries the
annotation's full source text — what the opt-in avoids is a second, parsed
copy, and the comment now says so.

The test file is renamed: `spring-handler-annotation-arguments` differed
from the pre-existing `spring-annotation-arguments` by one word in the
middle, though they cover different mechanisms — an AST capture versus a
text parser. It is now `spring-argument-fact-capture`, after the module it
exercises.

* docs(ingestion): correct the argument-text contract the normalizer outgrew

Both `SpringNonHttpHandlerAnnotationFact.args` and `SpringArgumentFact.text`
promised the value stays "exactly as written". That was true when the field was
added and stopped being true in the same branch, when argument text started
going through `normalizeSpringFactText` so that one destination written across
two lines would not compare unequal to the same reference on one line.

A consumer reading only the interface would have assumed a source spelling the
fact does not retain — and the indentation such a consumer would have seen is
the enclosing block's, not a property of the expression at all.

Both docs now state the single rewrite and its reason, and still say plainly
that nothing is resolved. Reported by the review bot on #3128; the claim was
introduced by this branch, not inherited.

* style(ingestion): apply Prettier to the four files CI flagged

`quality / format` runs `prettier --check .` and four files from this branch had
drifted: two line-width wraps and two of the opposite kind, where a call fits on
one line. No behaviour change — tsc clean, the four affected suites still pass
126 tests.

Worth noting why the pre-commit hook did not catch it: lint-staged formats
staged files, but a rebase replays commits without running hooks, so anything
that only becomes unformatted relative to a moved base slips through. Checking
the whole diff against `prettier --check` before pushing is the reliable step.

* test(ingestion): publish Kotlin named arguments through a Kotlin template

Kotlin forbids named arguments when the callee is a Java method: parameter
names are not guaranteed to survive into bytecode, so the compiler refuses
`kafkaTemplate.send(topic = ..., data = ...)` for the Spring `KafkaTemplate`
imported from `org.springframework.kafka.core`. Every named-argument example
in this feature was written that way, which asserted capture on source that
could never compile.

The path itself is real and stays covered. The classifier matches on the
receiver's NAME, so a template declared in Kotlin is recognized exactly like
the Spring one, and named arguments to it are legal. Each affected example now
declares that template and publishes through it; the assertions are unchanged
except for the one receiver spelling they name.

The fixture's `publishWithNamedArguments` had no test reading it at all, so it
carried the illegal shape into an app fixture for nothing. It is removed, and
the two pipeline expectations that counted its publish drop a row.

* fix(ingestion): withhold a broker when the receiver name matches two templates

Widening the receiver-name rule from a suffix to a substring — needed to accept
`kafkaTemplateDlq`, `KAFKA_TEMPLATE`, and the rest — also let ONE receiver
satisfy TWO signatures. `KafkaTemplate` and `StreamBridge` both publish through
`send`, `RabbitTemplate` and `JmsTemplate` both through `convertAndSend`, so
`streamBridgeKafkaTemplate.send(...)` matched twice and the loop returned
whichever came first in the list: kafka, by declaration order alone.

The receiver's TYPE is deliberately never resolved here, so nothing in this
module can rank the two matches. Neither the longest match, nor the last one,
nor the order of the signature list is evidence about the bean: that name reads
equally as a KafkaTemplate fronted by a stream binding or a StreamBridge named
after the broker behind it. Publishing one of them as the template turned an
unanswered question into a definite attribution a consumer has no way to
distinguish from a resolved one — a publish routed to the wrong broker.

An ambiguous receiver now yields no fact at all. That costs a rare publish,
stays recoverable by a later phase that owns type information, and is the
failure this capture already prefers everywhere else. Both outcomes are pinned:
three receivers naming two templates yield nothing, while decorated names that
merely look long (`orderStreamBridge`, `streamingKafkaTemplate`) still resolve.

The `typeName` contract said "suffix", which the same widening had made false.

* docs(ingestion): correct two argument contracts this change set invalidated

Sweeping the Spring capture comments for claims the feature commits outgrew
turned up two more, both about what a MISSING argument list means.

`SpringNonHttpHandlerAnnotationFact.args` promised that absence means the
annotation was written without an argument list. Reading Kotlin arguments on
evidence gave absence a second cause: Kotlin still produces a fact for every
annotated function — it has no name prefilter, so an import alias cannot hide a
handler — but reads arguments only for callables carrying a handler annotation,
so a non-handler fact has no arguments however its annotation was written. Java
produces facts for handler-bearing callables only, so there the old reading
still holds. The field now states both causes and which language has which.

`SpringArgumentFact.name` said a template call gives its destination by
position. That is true of Java, which has no named arguments, but Kotlin names
call arguments whenever the callee is declared in Kotlin, and this module
captures the key when it does — the reason the field exists for calls at all.

* fix(ingestion): make the Kotlin argument reader refuse recovered syntax itself

`kotlinValueArgumentFacts` is exported and already has a caller in another
module, and its contract said the caller MUST reject a recovered list first.
Both callers did. But a guard that every future caller has to remember is the
same fragility this change set exists to remove — the Java twin is safe only
because it is module-private with one call site.

It now returns `null` for a recovered list, so the decision is unavoidable at
the type level, and each caller answers in the way its fact requires: a producer
call drops the whole fact, having no state for "published somewhere unreadable",
while an annotation reports no arguments and collapses into the marker form.
Both say "nothing here to resolve", which is true.

No behaviour change — the same 126 tests across the three affected suites pass,
including the truncated-annotation and truncated-call cases that pin the
fail-closed path.

Raised as hardening in the maintainer review of #3128.

feat(kotlin): bind Spring config consumers on Kotlin sources (#3126)
* feat(kotlin): bind Spring @Value and ConfigurationProperties consumers

Kotlin sources were skipping the Java-only config-binding attach path, so mixed JVM apps under-reported blast radius for Kotlin placeholders. Capture from the live AST, serialize on the existing side channel, and reuse the shared binder. (U1-U4)

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

* test(kotlin): add config-consumer capture benchmark and fix JVM feature stamps

The Kotlin capture path had no performance or behavior guard: a file-wide
lexical shadow regression silently dropped two of every three facts. The new
bench arm fingerprints @Value / @ConfigurationProperties facts from an
explicit-import control against a wildcard-import corpus whose files each
declare a sibling nested `Value` type, so parity between the arms is the
regression gate, and CI runs it with scaling + widening budgets.

Broadening spring.config-bindings to .kt also means Kotlin-only JVM repos now
stamp the feature, which the two exact-map orchestration expectations still
denied.

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

* fix(kotlin): let an explicit import shadow the Spring wildcard import

importedAs accepted a star import of the Spring package even when the same
simple name was explicitly bound to another type, so a file importing
com.example.Value alongside the Spring annotation package emitted a false
@Value consumer fact. Kotlin resolves the explicit import first, so the
wildcard branch now only applies when the name is otherwise unbound.

feat(jvm): fold Java static wildcards and Kotlin star imports for route constants (#3110)
* feat(java): expand wildcard static imports + POSIX-space import resolution

- `import static a.b.C.*` records the class FQN at extract time
  (ModuleConstants.wildcardImports) and expandJavaWildcardStaticImports
  materializes the bare-name bindings once the repo constants map exists,
  mirroring explicit single-member static imports. Wired in both the
  group-side prepareRepo fold and the ingestion-side parse-impl pass so
  the two query surfaces cannot diverge. Without this, wildcard-imported
  route constants (~693 routes on our monorepo) silently failed to fold
  and their provider contracts were dropped.
- resolveJavaImport compares in POSIX space (backslash-normalized repo
  keys) — on Windows the '/'-joined class file never matched a
  backslash-keyed repo (observed: 675 calls, zero hits).
- Wildcard bindings never overwrite single imports (a member shadowing
  its own wildcard is honored); unresolved wildcards degrade to the
  existing skip floor.

Rebased onto current main: the parse-worker gate this originally carried
is superseded by the provider moduleConstantHeuristic architecture; only
the resolver-side wildcard expansion and POSIX tolerance remain.

* chore(cache): claim SCHEMA_BUMP 83 (82 taken upstream by Spring lookup facts)

* style: prettier

* fix(java): make wildcard static imports actually resolve route constants

extractJavaModuleConstants never populated wildcardImports, so
`import static a.b.C.*;` was inert: the asterisk is a sibling of
scoped_identifier in tree-sitter-java, not a path segment. Record the
class FQN there and stop binding the class simple name as a field.

Wildcard-only files also fell through every harvest gate (the java
provider heuristic regex, the parse worker emit check, and the group
prepareRepo filter), so the constants never reached either layer.
Expansion now resolves targets against constant-defining files only,
keeping ingestion and group in parity (#2980 R4).

Adds unit coverage for extraction, expansion/shadowing, the unresolved
skip floor, the harvest heuristic, Windows path keys, and group <->
ingestion parity.

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

* feat(kotlin): fold package-star imports for route constants

Kotlin `import pkg.*` now records star scopes and resolves unique
top-level names after local and explicit imports, matching the Java
wildcard path without accepting invalid object-star imports.

Reuse a Java constant-file suffix index across expansion so
wildcard materialization stays linear as both constants and
importers scale. Add named-vs-star benches and CI --check gates.

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

* fix(jvm): fold wildcard imports without shadowing locals or skipping same-package names

Keep Java unfoldable declarations from being resurrected by static wildcards, bind only the target type's members, and prefer Kotlin same-package names over package-star imports. Move repo-wide preparation behind a language-provider hook so the shared parse phase stays language-agnostic.

fix(group): make degraded links, sync warnings and UID-only impact actually work (#3113)
* feat(group-surface): impact selector pass-through + degraded links + sync hygiene

- @group impact forwards target_uid/file_path/kind through service port
  and cross-impact impactParams (was dead-wired: params accepted at MCP
  boundary then dropped at validation).
- crossLinks with unresolved provider symbols carry degraded: true,
  derived at the persistence boundary after merge/dedupe; sync reports
  'degraded links: N' and per-repo extraction failures instead of
  swallowing them; bridge write failures surface as sync warnings;
  contracts.json passes through dedupeContracts.
- Absolute-URL branch restores %7B/%7D around {param} after URL parsing.
- tests: consumer matrix + wildcard folding + degraded pins (261 new);
  SCHEMA_BUMP pin 47 -> 48 (wildcardImports cache shape); sync.ts NUL
  byte rewritten as text escape (no longer binary to git).

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

* fix(group): impact selector pass-through, degraded links, sync failure hygiene

- @group impact forwards target_uid/file_path/kind through the service
  port into cross-impact impactParams. These were accepted at the MCP
  boundary and then dropped in validation — a dead wire: disambiguating
  an ambiguous impact target never actually reached the per-member impact.
- Cross-links whose provider endpoint never resolves to a graph symbol are
  marked degraded: true at the single persistence boundary (post
  merge/dedupe, before re-export), counted as SyncResult.degradedLinks,
  and surfaced by the sync summary ('degraded links: N') — the remedy
  (re-analyze the provider repo) is documented on the field.
- Sync failure hygiene: a repo whose per-repo extraction throws records
  its reason in SyncResult.failedRepos (still lands in missingRepos, so
  downstream semantics are unchanged) instead of the old silent swallow
  that could persist half a repo's contracts; operator warnings
  accumulate in SyncResult.warnings.

Tests: cross-impact selector threading, degraded-link marking, per-repo
failure reporting.

* style: prettier

* fix(group): make degraded links, sync warnings and UID-only impact actually work

The three fixes this branch claims were wired at the type and payload level
but never at the boundary that produces the values:

- `degraded` was only ever cleared by the exported `dedupeCrossLinks`, which
  the sync path does not use, so `degradedLinks` was always 0. Derivation now
  lives in one exported `applyDegradedFlag` that both the sync finalize and
  the post-merge re-derivation call.
- The bridge-write catch logged an operator warning and dropped it, leaving
  `warnings` permanently `[]`.
- `@group impact` rejected a UID-only call before it parsed `target_uid`, so
  the documented "re-call with target_uid" disambiguation loop was
  unreachable in group mode even though the selectors were forwarded.
- `failedRepos[].repo` reported the registry display name while the repo
  landed in `unreadableRepos` under its group path, so the two lists could
  not be joined; the JSDoc also pointed at the wrong list.
- Restored the truncated `READ THE RESULT:` heading in the group_sync tool
  description and documented degradedLinks / failedRepos / warnings.

Tests pin each value at the boundary that produces it, including the exact
group_sync wire shape, which previously omitted all three new fields.

fix(server,web): honor the grep tool contract — real regex, fileFilter, caseSensitive (#3109)
* fix(server,web): honor grep tool contract — real regex, fileFilter, caseSensitive (Patch 12)

Background
==========

The web chat's grep tool schema has always promised regex search with an
optional path-substring fileFilter and caseSensitive control, but the
GET /api/grep handler escapeRegExp()'d every pattern into a literal
substring (a ReDoS hardening from fa36254e / #1317 that never re-synced
the tool contract). Consequences, verified in production use against the
sr-next backend repo (23k-file Java monorepo):

- An agent sending the documented alternation form ("sign|Sign") got
  zero hits and concluded the sign/签署 interface did not exist.
- The schema's own example pattern ("console\\.log") could never match:
  the escaped literal searched for a backslash in the source.
- fileFilter / caseSensitive were read by nobody — pure schema fiction.
- The web handler worked around the server with a (?=.*filter).*pattern
  lookahead splice that the same escaping also defeated.
- Collateral: the impact tool's grep fallback (\b${escapeRegex(name)}\b)
  was silently dead code under literal semantics; it comes back to life
  with this fix (expected improvement, noted for reviewers).

Fix
===

Server (gitnexus):
- New src/server/grep-params.ts — pure query-param parser (no Express /
  native imports, per the #2790 helper-extraction convention):
  regex construction (default real regex; literal=1 restores the old
  escaped-substring semantics as an opt-out), lowercase path-substring
  fileFilter, caseSensitive flag, limit clamp [1,200] default 50,
  BadRequestError error paths (mapped to 400 by statusFromError).
- /api/grep handler in api.ts becomes thin wiring: fileFilter path
  filtering before the (unchanged) traversal guard, a 5s wall-clock
  budget checked between files (partial results plus timedOut: true),
  read-only DB open unchanged. The regex is deliberately built WITHOUT
  the 'g' flag: the handler tests line-by-line and a stale lastIndex
  would skip matches (the old code had to reset it manually); 'm' is
  likewise omitted — each test sees one line, so ^/$ already anchor at
  string boundaries.

Web (gitnexus-web):
- tools.ts: drop the lookahead splice; description now tells the model
  the truth (real regex, alternation works, path-substring filter,
  case-insensitive default, result cap and time budget).
- backend-client.ts: grep() takes GrepOptions {fileFilter,caseSensitive}
  and forwards them as query params.
- useAppState.tsx: assembly site threads the options through.

Security — residual ReDoS exposure (read this before deploying)
===============================================================

The literal-only era was accidentally ReDoS-immune; this patch knowingly
trades that immunity back for the promised contract. The bounds (200-char
pattern cap, line-by-line matching, result cap, 5s budget) do NOT cover a
single catastrophically backtracking regex.test(): it blocks the Node
event loop synchronously, the budget (checked between files) cannot
interrupt it, and the whole server is unresponsive for the duration
(measured: (a+)+$ against a 35-char line exceeds 120 seconds). Accepted
because local serve binds loopback by default and hosted deploys gate
/api/grep behind the edge token; documented in SECURITY.md (new section)
with the worker_threads+terminate / optional-re2 follow-up called out.
literal=1 restores full immunity for untrusted callers.

Compatibility audit
===================

Repo-wide: /api/grep's only HTTP caller is backend-client.grep(); the MCP
tool surface has no grep tool; eval/ uses shell grep, not this endpoint;
the endpoint is undocumented (docs/llms.txt) with no known third-party
consumers. Breaking surface ≈ zero. Pattern metacharacter semantics
change for direct curl users ("array[0]" now needs escaping or literal=1).

Tests
=====

+20 cases in test/unit/grep-params.test.ts: alternation (the regression
that burned the agent), the schema's own example, case flags, literal
compat, CJK patterns, ^/$ line anchors, fileFilter normalization +
array-form rejection, limit clamping, type-confusion guards, invalid
regex, and a source-level handler wiring assertion (api-readonly-wiring
style). Full unit suite: no new failures (22 pre-existing failures
reproduced identically with this patch stashed — analyzer-identity dist
fingerprint + lbug native-env classes).

Upstream plan
=============

Issue + PR to abhigyanpatwari/GitNexus; the PR description must front the
ReDoS trade-off with the worker-isolation follow-up. Repro for the issue:
curl ".../api/grep?pattern=TODO%7CFIXME" — 0 hits under literal
semantics, both marker classes under regex semantics.

Custom-patch ledger: CUSTOM_PATCHES.md Patch 12.

* style: prettier

* fix(web): surface grep timedOut so partial scans are not silent misses

Propagate the server timeout flag through the backend client and chat tool, check the 5s budget between lines, and document the accepted regex-injection CodeQL finding next to new RegExp.

* Address PR review feedback (#3109)

- Cover empty and null fileFilter in the grep client test
- Keep timedOut as a required boolean and reuse GrepOptions
- Sample the grep deadline every 256 lines instead of every line

Note: pre-existing failure in impact-tool.test.ts not addressed by this PR.

* Address PR review feedback (#3109)

Run /api/grep matching in a worker_threads worker so terminate() can
cut a catastrophic regex.test without blocking the parent event loop.

* Address PR review feedback (#3109)

Reset lastIndex per line, restore the missing-pattern 400 message, and
make the traversal test create a real outside file.

* fix(web): align agent grep opts with GrepOptions

Use GrepOptions so fileFilter null is accepted by the local GraphRAGBackend stub.

* fix(server): silence CodeQL js/regex-injection on intentional grep regex

Split literal vs regex construction and suppress with the correct rule id
(js/regex-injection). Real regex remains the default contract; literal=1
still escapes.

* Address PR review feedback (#3109)

Clean up grep-scan temp dirs after each test, and exclude the intentional
grep-params RegExp site from CodeQL so js/regex-injection does not re-file.

feat(jvm): synthesize Lombok and Kotlin JVM accessor methods (#2885)
* feat(java): synthesize Lombok @Data/@Getter/@Setter accessor methods

* fix(lombok): resolve class identity by AST node id, not simple name

Root-cause fix for the bot review's name-ambiguity findings:

1. Cross-file collision: the owner map was rebuilt per file from
   result.symbols, which accumulates across the whole language group —
   a later Java file with the same simple class name resolved to the
   earlier file's class node. The map is now filled INSIDE the capture
   loop (per-file scope) and keyed by the class_declaration AST node
   id (SyntaxNode.id), which is unique by construction.

2. Same-tail nested classes (Outer.A vs Other.A): a name-keyed map
   overwrote one with the other; AST-node-id keys cannot collide.

3. Synthesized method ids now follow the SAME convention real nested
   member ids use (keyed by the class's own simple name, matching
   findEnclosingClassInfo().className), so call resolution can hit
   synthesized accessors exactly like hand-written ones.

4. Lombok semantics: setters are no longer generated for final fields
   (Lombok never emits those) and @Setter(AccessLevel.NONE) now
   suppresses setters, symmetric to the existing getter suppression.

Also tightens two vacuous test loops flagged by the bot (empty-array
for..of passed trivially): counts are asserted before property loops,
and a new regression test pins distinct owners for same-tailed nested
classes plus the real id convention for nested accessors.

* feat(java): synthesize Lombok accessors via provider hook and scope dual-path

Replace the worker language===Java branch with LanguageProvider.synthesizeStructureMembers,
align MethodRegistry ownership through scope captures, and bump parse-cache schema to 83
so warm caches cannot replay pre-synthesis worker output.

* test(java): cover Lombok synthesis semantics, cache replay, and CI bench

perf(store): V8 sidecars plus hardlinked ParsedFile restore (#3099)
* perf(store): add best-effort V8 sidecars beside canonical JSON caches

Warm ParsedFile and parse-cache loads skip JSON.parse when a sidecar is present. JSON remains authoritative: envelope validation plus v8.deserialize decide the hit, and any failure falls back without reparsing.

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

* fix(store): require generation bind or sidecar drop before cache overwrite

A same-length JSON rewrite could accept a leftover V8 sidecar if both
generation rotation and unlink failed. Refuse the new generation unless
at least one of those invalidations succeeds; skip publishing a sidecar
when only the drop succeeded.

detect_changes --scope all: 7 files, risk low, no affected processes.
tsc --noEmit clean; 115/115 relevant unit tests; cache-related
integration tests pass. parse-impl-env-reads worker-ready timeout is
pre-existing (same 5 failures with this change set stashed). ESLint 0
errors; remaining warnings are pre-existing and not on changed lines.

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

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

* refactor(store): share V8 overwrite invalidation across persist paths

The bind-or-drop gate lived in five writers. One helper keeps the

* perf(store): hardlink durable ParsedFile shards into the run store

Warm restore of parsedfile-cache into parsedfile-store now publishes all four shard files via fs.link, falling back to copy-into-tmp + rename so a leftover dest hardlink can never be written through. JSON remains the canonical cache; V8 sidecars ride the same path.

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

* perf(store): load immutable V8 shards in place, drop JSON fallback

Warm analyze was still paying JSON.parse plus a restore copy. One .v8 envelope per shard and SCHEMA_BUMP 81 make a miss re-extract instead of serving a stale JSON twin.

fix(analyze): make incremental analyze skip the derived layers it can reuse (#3016) (#3102)
* fix(analyze): make incremental analyze skip the derived layers it can reuse (#3016)

A warm incremental run only ever wrote a handful of files, but it still
paid for the whole graph on the way out: Leiden ran over every node,
flow extraction re-derived every process, and all FTS indexes were
dropped and rebuilt from scratch. On a small edit that tail dominated
the run, which is why "incremental" did not feel incremental.

Reuse what the previous run already derived when the write plan allows
it. The pipeline holds back community detection and flow extraction
whenever the persisted metadata says this run is a candidate for a
surgical write; the DB keeps its Community/Process rows instead of a
wipe-and-rewrite; and the FTS sweep is narrowed to the indexes the run
actually has to touch.

The bet is placed before the pipeline and settled after it. Any plan
that turns out to need a freshly derived layer — full rebuild, escalated
write, or an incremental diff with deleted files — runs the held-back
phases through `runDeferredDerivedPhases`, against the same graph and
phase outputs, so its output is identical to never having skipped them.

Correctness details worth naming, since each one silently loses data if
got wrong:

- The MEMBER_OF / STEP_IN_PROCESS edges of the changed files are snapshotted
  before the DETACH DELETE and reattached after the subgraph load. Both
  endpoints are matched by explicit label: `labels(n)[0]` over an unlabelled
  match returns an empty string on this engine, which produced a snapshot
  that restored nothing.
- The FTS narrowing unions three sets — what the writeback deletes (a DB
  probe, because a symbol the edit removed is in no fresh graph but is
  still a row), what it inserts (the fresh graph), and what is missing
  right now (else a prior escalation's dropped indexes would never come
  back). An unreadable index catalog withdraws the narrowing entirely.
- Deletions disqualify reuse outright: persisted derived rows can reference
  nodes this run removes, and nothing short of re-deriving can tell which.

Covered by the existing incremental suites, including the
incremental-equals-force byte-equivalence test and the #2589
drop-before-delete ordering test, plus unit tests for the new helpers.

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

* fix(analyze): address #3102 review on derived reuse and FTS narrowing

Re-run Leiden/flows unless the file-hash diff is empty, restore ENTRY_POINT_OF

assertions unblock CI and pin the #2589/#3016 contract.

fix(status): judge freshness by covered files, not a dirty working tree (#3083)
`gitnexus status` reported "stale (re-run gitnexus analyze)" whenever the
working tree held any modified or untracked file, including files the index
never reads. Because `analyze` cannot commit, stash or delete such a file,
the remedy it prescribed could not clear the verdict — the only way back to
up-to-date was to remove the file.

`meta.fileHashes` already records the exact set of files a run covered, so
answer the question directly: compare those hashes against disk, reusing
analyze's own scan, hash and diff helpers so the two cannot disagree about
what "changed" means. A new coverable file still counts as stale (the index
is genuinely incomplete then), but one `analyze` now settles it. The
repo-wide dirty flag survives only as the fallback for metadata written
before `fileHashes` existed.

Both freshness checks now read GitNexus's own analyze output (AGENTS.md,
CLAUDE.md, the agent skill mirrors) from one shared list. They previously
held separate copies, and since analyze rewrites those files after
recording hashes, a per-file comparison that missed them would report a
freshly indexed repository as permanently stale.

* feat(wiki): add grok local CLI provider

Wiki generation can use `gitnexus wiki --provider grok` to spawn the
authenticated Grok Build CLI (`grok --prompt-file`) instead of an HTTP API key.

* style(wiki): prettier grok-client for CI format check

CI quality/format failed on grok-client.ts. Auto-format matches repo prettier so the GitNexus /autofix comment is applied locally.

* Update Grok CLI configuration to use empty allowlist and increase max tu

* Replace Grok tool allowlist with explicit denylist and strict sandbox

* Increase Grok max turns to 15 to accommodate prompt variance

* chore(wiki): drop Unreleased CHANGELOG hunk and restore lockfile libc selectors

Feature PRs do not own CHANGELOG.md. Restore the 16 libc platform selectors
deleted from package-lock.json with no dependency change.

* fix(wiki): resolve grok CLI through Windows cmd.exe shims

Extract resolveWindowsCliCommand from the local CLI client and use it for
grok detect/spawn so npm .cmd installs work without a shell. Keep
detectGrokCLI() returning the display name for the wiki menu.

* fix(wiki): wait for grok child close before timeout cleanup

Do not reject the grok spawn promise on the timeout timer. Kill the child,
escalate SIGKILL after 2s, and reject only on close (or a second 2s hard
deadline) so callGrokLLM cannot rm the sandbox while the process is alive.

* fix(wiki): reject incomplete grok stopReason and distinct parse errors

Honor JSON stopReason (end_turn or omitted succeeds; anything else throws).
Split empty-output / non-JSON / missing-text messages and include a truncated
stdout excerpt. Drop unused GrokConfig.workingDirectory.

* fix(wiki): keep grok temp dir on hung timeout and ignore stdin

Hard-deadline reject no longer removes --cwd while the child may still
be running. Spawn stdin is ignored so grok's unused pipe cannot EPIPE
the wiki process.

Co-Authored-By: Grok 4.6 <grok4.6@x.ai>

* fix(wiki): require grok stopReason=end_turn for a finished page

Live grok 1.0.5 with wiki spawn flags returns stopReason end_turn.

PHP: detect generated-client Request(method, host . resourcePath) consumer shape (#3079)
* feat(group/php): detect generated-client Request(method, host . resourcePath)

openapi-generator-php / swagger-codegen PHP clients build every operation as
`$resourcePath = '/foo/bar'; ...; new Request($method, $host . $resourcePath);`
— a shape the PHP consumer patterns didn't cover (only `$client->verb('/path')`
literal calls were matched), documented in the module's own docblock as a
follow-up ("constant-folding the surrounding scope").

Adds a pattern for `new [Qualified\]Request(...)` constructor calls, with a
conservative, single-scope backward constant fold: the last variable in the
path argument's concatenation chain (generated clients build
`<host> . <resourcePath>`) is resolved to a `$var = '<literal>';` assignment
in the same enclosing function/method body (or file scope) if one exists
earlier in the same scope. No interprocedural resolution — a miss just
leaves the endpoint undetected, never a wrong one.

The HTTP verb is often itself a parameter in these generated clients (not a
literal at the call site), so when it can't be resolved to a literal the
detection reports a wildcard method (`'*'`), consistent with this project's
existing manifest-link convention for a contract whose verb isn't pinned.

`hasConsumerSignals` is widened to stay a proven superset of what `scan()`
now detects (required by its own contract, checked by
`http-consumer-signals.test.ts`).

The docblock notes this is a deliberately narrow, single-scope fallback, not
this language's entry into the shared cross-file constant-fold the other
languages use (`constant-resolver.ts`, wired in via `java-const-resolver.ts`
/ `python-const-resolver.ts` / `js-const-resolver.ts`) — PHP has no such
binding yet; adding one is a separate, larger project (this repo's PHP
import resolution for `use`-statements is its own multi-file subsystem built
for symbol/scope resolution, not constant extraction) and is out of scope
here.

Tests: 7 scan()-level cases (resolution across a member-access host,
fully-qualified class name, purely literal call, negative — different
function scope, negative — non-Request constructor, negative — non-HTTP
literal, picking the LAST var in a 3-part concatenation), plus 2 new
hasConsumerSignals cases and a negative. `tsc --noEmit` clean, `eslint`
clean, full test/unit/group green (1035+/1037; 2 pre-existing native EBUSY
failures on a `.lbug` file in bridge-meta-swap-window.test.ts, unrelated
subsystem, reproduces in isolation on unchanged upstream too).

* fix(group/php): fix two code-review findings in guzzle-request-ctor

1. lastConcatVariable silently returned the WRONG variable for a
   parenthesized right operand: `$host . ($resourcePath . $suffix)` fell
   through to the left operand (unhandled parenthesized_expression) and
   returned $host instead of looking inside the parens. Restored parenthesis
   unwrapping (present in an earlier draft, dropped during a simplification
   pass that didn't account for this fallthrough).

2. resolveLocalStringLiteral stopped at the nearest compound_statement, so
   a `new Request(...)` call nested in `if`/`try`/`foreach` inside the same
   function couldn't see an assignment made just above that block — despite
   the docblock's claim of covering the "enclosing function/method body".
   Now widens level by level (search the immediate block's preceding
   statements, then its own enclosing block, and so on), stopping at
   `program` so it still never crosses into a different function or the
   containing class body — verified by a regression test asserting exactly
   that boundary.

Also documents the line-number choice (path argument, not the `new Request(`
call site — the two differ for this pattern's characteristically
multi-line calls) inline, matching the other three consumer patterns'
convention in this file.

4 new regression tests (35 total in this file's suite): parenthesized
right operand no longer mismatches, enclosing-block resolution across an
`if`, and a negative case proving the widened search still respects the
function boundary. tsc --noEmit clean, eslint clean.

* fix(group/php): address gitnexus-check bot review on PR #3079

1. resolveLocalStringLiteral fell through an intervening non-literal
   reassignment: `$v = '/old'; $v = buildPath(); new Request(..., $v)`
   resolved to '/old' even though $v never holds that literal at the call
   site. The NEAREST assignment to the target variable now decides the
   outcome unconditionally — a non-string RHS stops the search (returns
   null) instead of letting the scan continue past it to an older,
   shadowed literal. This was a real "wrong answer", not a miss, directly
   contradicting the function's own documented invariant.

2. lastConcatVariable recursed into every binary_expression regardless of
   operator, so `$host && $resourcePath`, `$host + $resourcePath`, and
   `$host ?? $resourcePath` were walked exactly like `.` concatenation.
   Now checks operator === '.' before recursing.

3. hasConsumerSignals matches case-insensitively (`/i`), correctly, since
   PHP class names are case-insensitive at the language level — but scan()
   compared the resolved class name to 'Request' case-sensitively, so a
   valid `new request(...)` / `new \NS\REQUEST(...)` call would pass the
   parse-skip gate as a signal and then be silently dropped by scan()
   itself. Both sides now agree (case-insensitive compare in scan() too).

4. The first test's own PHP source assigned `$method = 'POST';` as a local
   variable but asserted `method: '*'` with a comment calling it "a
   parameter" — it wasn't; it was exactly the same locally-resolvable shape
   as $resourcePath. Fixed by (a) rewriting that test's source to show
   $method as a genuine function parameter (the shape generated clients
   actually use — the verb is fixed by the caller of the builder method),
   which is what the test intended to demonstrate, and (b) actually
   implementing symmetric resolution: method now resolves through the same
   resolveLocalStringLiteral fold as path when it IS a local variable,
   with a new test proving that case resolves to a literal method instead
   of a wildcard.

5 new regression tests (39 total in this file's suite, up from 35):
non-literal-reassignment shadowing, non-concatenation operator rejected,
case-insensitive class name match, and local-variable method resolution.
tsc --noEmit clean, eslint clean.

* fix(group/php): address second round of gitnexus-check bot review

1. Backward fold missed reassignments nested inside a preceding if/foreach/
   try/switch: the scan only recognized direct expression_statement
   siblings as candidate assignments, so `if ($cond) { $v = '/new'; }`
   right before the call was invisible, and an OLDER, now-shadowed literal
   outside that block was returned instead — a real wrong answer whenever
   that branch runs. Any non-assignment sibling that contains an assignment
   to the target ANYWHERE inside it now stops the search (miss) rather than
   being skipped over, since whether that branch ran is unknown.

2. Level-by-level scope widening crossed anonymous-function boundaries
   without checking PHP's actual capture rule: closures capture NOTHING
   automatically, only variables listed in `use (...)` are visible inside
   — unlike arrow functions, which auto-capture everything and have no
   `compound_statement` body (never seen as a scope by this walk at all).
   Widening past a closure's body now checks its `use (...)` clause first;
   real PHP would throw "Undefined variable" for anything not captured,
   not resolve to a value from the enclosing scope.

3. lastConcatVariable still fell through to the LEFT operand whenever the
   right one wasn't a variable-or-nestable-expression — `new Request($m,
   $host . '/users')` (a trailing string literal, not a variable) resolved
   to $host instead of recognizing there's simply nothing to resolve at
   that position. Removed the left-operand fallback entirely: the
   rightmost position decides, full stop, matching the function's own
   "single lookup, not a fallback list" docblock (which the previous round
   already stated but the code didn't yet fully honor for this case).

Also strengthened a test that the bot correctly flagged as non-diagnostic:
"ignores an unrelated constructor" used an unresolvable $resourcePath, so
it would have passed even with the class-name filter deleted. Now uses a
fully resolvable path so the class-name filter is what the assertion
actually exercises.

4 new regression tests (43 total, up from 39): shadowed-by-conditional-
reassignment, closure boundary without use()-capture (negative), closure
boundary WITH use()-capture (positive control), and trailing-literal
concatenation no longer mistaken for the host variable.
tsc --noEmit clean, eslint clean.

* chore: trigger re-review (previous gitnexus-check report cited stale line numbers)

* fix(group/php): stop scope widening at a function/method boundary

The digest posted on PR #3079 (verified against the current file, not the
stale HEAD it was generated from — three of its four findings were already
fixed in prior commits) reproduced a real, still-present fourth issue:
after exhausting a method's own body, widening continued straight to
`program` (file/script scope) and could resolve a top-level variable into
a class method — but PHP methods (and plain functions) have NO access to
file-level variables without an explicit `global $v;`, which this resolver
intentionally never adds support for. A file-level `$resourcePath = '/x';`
could therefore leak into an unrelated method's `new Request(...)` as a
real, wrong answer.

Widening now stops unconditionally at a `function_definition` or
`method_declaration` boundary — these get no automatic capture and no
implicit global in PHP, unlike closures (already handled: an
`anonymous_function` boundary stops unless `$target` is `use()`-captured).
The call-site-at-file-scope case still resolves correctly, since `program`
is reached directly there with no boundary to cross.

3 new regression tests (46 total): file-scope variable does not leak into
a class method, does not leak into a plain top-level function either, and
a positive control confirming file-scope-to-file-scope resolution still
works when there's no function boundary at all.
tsc --noEmit clean, eslint clean.

feat(group): resolve Kotlin constant-based route paths (@PostMapping(ApiPaths.X)) (#3059)
* feat(ingestion): resolve Kotlin constant-based route paths

`route-extractors/constant-resolver.ts` is the language-agnostic core for
folding constant references into literal route paths. Bindings existed for
Java, JavaScript/TypeScript and Python, but not Kotlin — so
`@PostMapping(ApiPaths.ORDERS)` resolved on Java sources and silently
produced no route on the identical Kotlin code.

Add `route-extractors/kotlin-const-resolver.ts` as the fourth binding,
mirroring `java-const-resolver.ts` (Kotlin shares the JVM package/import
model) in structure, naming and skip-floor discipline:

  * `resolveKotlinImport` — import specifier -> file path. Tier 1 matches the
    `<package>/<Name>.kt` convention; tier 2 falls back to the unique
    constant-defining file in the package directory, because Kotlin does not
    require a file to be named after the declaration it holds. Each tier is
    unique-or-nothing.
  * `extractKotlinModuleConstants` — parse tree -> `ModuleConstants`.
  * `parseKotlinConstOperands` / `foldKotlinOperands` — pre-bound wrappers so
    the calling side stays language-neutral, matching how `spring.ts`
    consumes `parseJavaConstOperands`.

Kotlin-specific forms handled explicitly rather than translated from Java:
top-level `const val`, `object` members, `companion object` members (keyed
under the enclosing class, since `Companion` never appears in a reference),
import aliases (`import a.b.C as D`), and the absence of a `String` type gate
(Kotlin infers property types, so the initializer decides). String templates
and multi-line raw strings are refused rather than folded with the
interpolation dropped, which would publish a path the application does not
serve. `var`, custom getters and delegates are not constants and are skipped.

Wiring: `group/extractors/http-patterns/kotlin.ts` gains a `prepareRepo`
pre-pass that builds the repo-wide constant map once per `extract()` run, and
`scan` now folds constant-valued `@(Get|Post|Put|Delete|Patch)Mapping`
arguments against it — the same shape the Java plugin already implements. A
constant-valued class-level `@RequestMapping` prefix suppresses the routes
under that class, as in `java.ts`: emitting them unprefixed would turn a
missing fact into a wrong one.

An ambiguous import returns null, never a guess — a duplicate fully-qualified
name across modules, a package with two constant files, and a wildcard import
all floor to skip. A wrong resolution is a false edge in the graph; a missing
one is only a missing fact.

The ingestion provider (`languages/kotlin.ts`) is deliberately left alone: the
ingestion fold runs only over `decoratorRoutes`, and Kotlin declares no
`extractDecoratorRoutes` because `spring.ts` is bound to tree-sitter-java.
Declaring the constant hooks there today would harvest a map nothing consumes.
The reasoning is recorded in the new module's header.

Tests cover each reference form (qualified, fully-qualified, single-name
import, concatenation incl. 3+ operand chains) plus every ambiguity case, at
both the resolver layer and through `KOTLIN_HTTP_PLUGIN.prepareRepo` + `scan`.

* test(group): cover the Kotlin route-fold guards left unpinned

Follow-up to the Kotlin constant-route binding, closing the test gaps a
review found. No behavior change: the only source edit is a comment.

  * Class-prefix suppression is now asserted for the NAMED spelling
    (`@RequestMapping(value = ApiPaths.BASE)`) as well as the positional
    one. The two take different branches of `kotlinRouteArgumentExpression`,
    and only the method-path side of the named branch was covered; a
    regression there would let a constant-prefixed class escape suppression
    and publish every method under it at an unprefixed path.

  * `MAX_FOLD_LENGTH` and both recursion caps are pinned from both sides.
    Output doubles per level while depth only increments, so 13 doublings of
    a one-character leaf land exactly on the limit and 14 overrun it; a
    30-link reference chain resolves where a 40-link one hits the
    cross-file cap; an 80-term `+` chain hits the operand-parse cap where a
    60-term one folds. A 30-level shared-descendant DAG folding inside a
    5 s budget pins the success memo that keeps it out of O(2^depth).
    These are the guards that keep a pathological constant graph from
    building a gigabyte-scale string or recursing without bound during a
    group sync; they were inherited from the audited Java binding but
    nothing held them in place.

  * OpenFeign consumers are covered on both paths: a constant method path
    folds, and a constant interface-level `@RequestMapping` prefix
    suppresses the consumer. The latter is deliberate — Spring Cloud
    prepends a type-level `@RequestMapping` to every method of the client,
    so an unfoldable prefix makes the remote URL unknowable whether or not
    `@FeignClient(path)` is present, and a dropped edge beats a wrong one.
    The suppression reaches an interface because tree-sitter-kotlin models
    `interface` as a `class_declaration`; `java.ts` misses this case only
    because its `findEnclosingClass` skips `interface_declaration`, and
    aligning Java changes Java's behavior, so it is left to its own change.
    Documented at the guard so the divergence is not read as an oversight.

Note for reviewers of the parent change: re-indexing a Kotlin Spring
service will REMOVE routes that were previously emitted, unprefixed, from
classes whose `@RequestMapping` prefix is a constant. Those paths were
never served by the application; the drop is the fix, not a regression.

* fix(group): suppress Kotlin routes only when the class prefix resolves to no literal

Class-prefix suppression decided "is this prefix unresolvable?" from a
three-element allow-list of node types (`simple_identifier`,
`navigation_expression`, `additive_expression`). An allow-list is safe for
FOLDING, where a forgotten shape yields no route, but it is the wrong shape
for SUPPRESSION, where a forgotten shape means "emit unprefixed" — a route
the application does not serve. `java.ts` gates on the ABSENCE of a literal
(`if (!valueNode)`) for exactly this reason.

The predicate is now inverted: a class is marked unless its `path`/`value`
argument is provably literal, recursing into `[…]` and `arrayOf(…)`
elements and refusing an interpolated `string_literal`. Measured against
the previous behavior, with `@PostMapping(ApiPaths.ORDERS)` under each
class prefix, on an app serving `/api/v1/orders`:

  * `[ApiPaths.BASE]`                   `POST /orders` -> dropped
  * `arrayOf(ApiPaths.BASE)`            `POST /orders` -> dropped
  * `value = [ApiPaths.BASE]`           `POST /orders` -> dropped
  * `buildPath()`                       `POST /orders` -> dropped
  * `if (USE_V2) "/api/v2" else …`      `POST /orders` -> dropped
  * `"${ApiPaths.BASE}"`   `POST /${ApiPaths.BASE}/orders` -> dropped

The last one published raw source text as a served path; refusing an
interpolated literal also fixes it for LITERAL method routes, which emitted
`/${ApiPaths.BASE}/list` before this branch existed.

Two regressions this suppression had introduced are repaired, both by
consulting the literal-prefix map that the pass above already built and
declining to mark a class that has an entry in it:

  * `@RequestMapping("/lit", ApiPaths.BASE)` + `@GetMapping("/list")` lost
    `GET /lit/list` entirely. Kotlin's vararg spelling leaves a resolvable
    arm behind, and suppression exists to avoid wrong routes, not to
    discard right ones.
  * `@FeignClient(path = "/api")` + `@RequestMapping(ApiPaths.BASE)` lost
    its consumer, though `path` outranks `@RequestMapping` when the URL is
    assembled and made the prefix perfectly knowable.

Two Feign emission paths never consulted the unfoldable set at all:

  * `@FeignClient(path = CONST)` was invisible to the analysis, which
    matches `@RequestMapping` only, so the client fell through to the
    no-prefix fallback and published `GET /orders` for a call the service
    makes to `/api/v1/orders`. Collected as its own set, kept separate
    because `path` outranks `@RequestMapping` in both directions.
  * The `@RequestLine` loop resolves through the identical "path wins"
    fallback chain but had no guard, so one interface could suppress its
    `@(Get|…)Mapping` route and publish its `@RequestLine` route under the
    very same unresolvable prefix. Both lanes now judge alike.

Note for reviewers: the `@RequestLine` guard is not a regression fix — that
lane emitted a wrong unprefixed consumer before this branch too. It moves a
wrong route to no route, on both sides of the change.

* fix(group): fold Kotlin route constants on Windows and when they fold to ""

Two defects in the Kotlin constant-path fold, plus the documentation
corrections review asked for.

Windows keys. `resolveKotlinImport` turns an import specifier into
`com/example/ApiPaths.kt` and asks whether a repository key ends with it.
The orchestrator's key list comes from glob v13, which has no `posix: true`
and joins with the platform separator, so on Windows every key arrives
backslashed and that test can never pass: the pre-pass still ran, the repo
context was still built, and every cross-file fold returned null — the
headline feature silently absent on one platform. Every unit fixture spelled
its keys POSIX, so CI could not see it. Normalized at the one boundary that
produces the keys — `prepareRepo`'s map keys and `scan`'s `fileRel` — which
is the fix `node.ts` and `python.ts` already apply for the same reason.
`readFile` still receives the raw path. Normalizing inside the resolver
cannot work: it returns the key it matched, so a normalized return value
would miss in a map nobody normalized.

Empty fold. `foldKotlinOperands` collapsed `''` into `null`, conflating
"folded to the empty string" with "unresolvable". `const val ROOT = ""` is
Spring's spelling for the class prefix itself, so under
`@RequestMapping("/api")` the literal `@PostMapping("")` published `POST
/api/` while `@GetMapping(ApiPaths.ROOT)` published nothing. Return the fold
unfiltered: callers already guard on `=== null`, `resolveKotlinConstant`
already returned `''` for the same constant, and this matches
`foldJavaOperands`.

Docs. The module header claimed the fold, the cycle guard and the depth cap
all live in the agnostic core. They do not — roughly 200 lines are a local
fork of the Java binding's already forked state machine, because the core
keys its maps by simple name while a Kotlin operand can be qualified at any
position. Say that, with the reason and the follow-up. The stated
`isKotlinConstantFile` invariant ("never rejects a file the extractor
accepts") is false: the extractor harvests a top-level non-`const` `val`
that fails both gate arms. The cost is not nil, either — measured, such a
constant in its own file loses every cross-file route, while the same
declaration beside the route still folds through `scan`'s on-demand
re-extract. Both recorded on the gate. The depth caps are now
`MAX_OPERAND_PARSE_DEPTH` (64) and `MAX_FOLD_DEPTH` (32); the core's own
`MAX_RESOLVE_DEPTH` is 8 and module-private, so it cannot simply be reused.

Measured with a differential probe over 41 Kotlin fixtures against the PR
base, in both key styles. Exactly one POSIX row moves — the empty fold —
and every other row, controls included, is byte-identical to before. POSIX
and Windows keys now yield identical detections on every fixture, on both
sides.

Deliberately not done: the `isKotlinConstantFile` gap is documented, not
closed, because closing it means parsing every file that contains any `val`.
`java-const-resolver.ts` still spells 64 and 32 inline. The PR body's
rollout note still says re-indexing activates the change — `HttpRouteExtractor`
runs during `group sync` (`sync.ts:297`), so that is a PR-body fix, not a
code one.

* fix(group): key Kotlin constants by visibility and resolve imports on the declared package

Two ways the Kotlin route fold could publish a path the application does not
serve. Both were inherited from the merged Java binding, which documents each as
accepted; the notes were wrong, not merely conservative, and both are left open
as a Java follow-up rather than changed here.

Simple-name flattening. Every `object`/companion member was recorded under BOTH
its qualified name `Owner.NAME` and its bare `NAME` in one file-level namespace,
so an initializer naming a sibling resolved through whichever object was walked
LAST:

  object A { const val BASE = "/right"; const val ROUTE = BASE + "/m" }
  object B { const val BASE = "/wrong" }
  @GetMapping(A.ROUTE)      // Kotlin serves /right/m; this emitted /wrong/m

Swapping the two objects flipped the answer back — the same source, merely
reordered, changed the emitted route. The bare key is also a binding Kotlin does
not have: `BASE` alone never names `A.BASE` from outside `object A`'s body, and
because the fold consults literals before imports, that fabricated key outranked
a genuine `import com.example.api.Paths.ORDERS` and published the local object's
value instead of the imported one.

Keys now follow Kotlin's own visibility. A member of a named `object` gets only
`Owner.NAME`; the simple name is recorded for a top-level `val` and for a
companion member, which really is in scope unqualified throughout its enclosing
class. Initializers resolve against their scope chain, innermost first, so `BASE`
inside `object A` means `A.BASE` — collecting every declaration before recording
any is what makes that independent of declaration order. An unfoldable object
member no longer drops a same-named import either, since it shadows nothing.

The known limit is now stated rather than argued away: a companion's bare key is
still file-wide, so two companions in one file whose members collide still
resolve last-wins for an unqualified reference. Kotlin scopes that to the
enclosing class and this map cannot express it — the fold is entered with a file
key and a name, and nothing says which class body the annotation sat in.
Initializers are unaffected; only a bare annotation reference can land wrong.

Import binding never read the `package` header. Both tiers picked candidates
purely from the path, so a file whose PATH ended with the imported FQN beat the
real declaration — and when the decoy declared the same constant the fold did not
skip, it invented a value. Measured: `object ApiPaths { const val ORDERS = "/right" }`
in `src/generated/Constants.kt` (`package com.example.api`) plus a decoy at
`src/x/com/example/api/ApiPaths.kt` (`package x.com.example.api`) emitted
`GET /wrong`. This falsifies the old docstring's safety argument, which only
covered a wrong file that LACKS the name. Two further triggers: a root-level
`package data` was impersonated by `com/example/data` on a path-suffix test,
while the real root-level file was invisible to the package-directory tier at
all; and a unique constant file under a test source tree folded into a
production route.

The declared `package` is now recorded per file and matched exactly. Candidates
that declare a different package are rejected rather than guessed at, an entry
with no recorded package is rejected too, and two files declaring the same
fully-qualified name resolve to nothing — a duplicated FQN names no single
declaration, so the test-source copy of a production constant is a skip, not a
guess about build configuration this layer cannot see. The file-name convention
survives only as a tie-break among candidates that already declare the right
package. `packageName` rides on a Kotlin-local `KotlinModuleConstants` rather
than widening the agnostic `ModuleConstants`, which Java, JS and Python share and
none of them needs it.

Measured with a differential probe over all 41 Kotlin fixtures, in both key
styles. Seven rows move, all of them from a wrong route:

  * sibling shadow, A first          /wrong/m   -> /right/m
  * bare key beats import            /wrong     -> /right
  * path-suffix decoy                /wrong     -> /right
  * root-package suffix match        /wrong     -> /right
  * root-package suffix only         /wrong     -> (skip; not in the repo)
  * test copy into production        /test-only -> (skip; FQN declared twice)
  * wrong file lacks the name        (skip)     -> /right

The last row is the one control that changes, and it changes from emitting
nothing to emitting the route Kotlin serves: its decoy declares a different
package, so the unconventionally named real file is now the sole candidate.
Every other row, all six remaining controls included, is byte-identical to
before, and POSIX and Windows keys still agree on every fixture.

Deliberately not done: `resolveKotlinImport` does not PREFER the candidate that
declares the sought name when several share the package — it only rejects when
two do. Preferring it would resolve more imports correctly (a package holding
`ApiPaths.kt` that declares something else and `Constants.kt` that declares
`ApiPaths`), but it is a separate skip-to-route improvement that would rewrite an
assertion this suite already pins, and the review round did not ask for it.

* fix(group): scope Kotlin companion constants to their class, and stop an empty path array suppressing routes

Three ways the Kotlin route fold still published the wrong answer, all measured
on fixtures rather than reasoned about, plus one comment that was false.

Empty path array. `hasResolvableLiteralPathElement` answered "does any element
resolve to a literal?", and `[].some(...)` is `false`, so `@RequestMapping(arrayOf())`
read as an UNRESOLVABLE prefix and suppressed every route under the class —
including a plain `@GetMapping("/lit")` that no constant fold ever touched.
Spring treats an empty array as NO prefix, so `/lit` is genuinely served. The
same arithmetic hit `@FeignClient(path = arrayOf())`, dropping a consumer.
Measured against the pre-suppression branch point:

  * `@RequestMapping(arrayOf())` + `@GetMapping("/lit")`  nothing -> GET /lit
  * `@FeignClient(path = arrayOf())`                      nothing -> consumer GET /orders

The predicate is now a three-valued `classifyPathArgument`: `'literal'`,
`'none'` (an empty array — no prefix), `'unresolvable'`. Only the last may
suppress, because "no prefix" is not "an unresolvable prefix" and only one of
them makes the served path unknowable. `@RequestMapping([])` is the same idea
spelled differently, but tree-sitter-kotlin does not parse the class carrying it
as a `class_declaration` at all, so no class-prefix pattern matches it and no
arm here can be reached — recorded rather than guarded against.

Companion scope. A companion member's simple name was recorded into the SAME
file-level namespace as top-level constants, and companions are recorded last,
so it won every unqualified reference in the file — including from a class that
is not its own. Kotlin binds it unqualified inside its enclosing class body and
nowhere else:

  * top-level `/top` vs an unrelated `Holder`'s companion `/companion`,
    referenced from a third class          `/companion` -> `/top`
  * two companions colliding on one name    `/h2`       -> `/h1`
  * `const val ROUTE = BASE + "/m"` at file level beside a companion `BASE`
                                            `/comp/m`   -> `/top/m`
  * a single-name import losing to a same-named companion outside its class

Only a TOP-LEVEL `val` now writes a bare key. The unqualified binding is reached
from the reference site instead: `scan` collects the enclosing type chain of the
annotation and `foldKotlinOperands` rewrites a bare operand to `<Owner>.<NAME>`
when an enclosing type declares it — innermost first, before the file-level maps
and before imports, which is Kotlin's own order. So the companion still wins
inside its own class (the control that pinned this behavior keeps passing) and
loses everywhere else. Nothing was skipped to get there: every one of the four
cases now emits the route the application serves.

An unfoldable companion member still drops a same-named import file-wide. The
import map has no scopes, and over-deleting costs a route while under-deleting
publishes the imported value at a reference the compiler binds to the unfoldable
member.

Backtick quoting. `` package com.example.`api` `` and `package com.example.api`
are the same package to the compiler — the quotes are lexical syntax, not part
of the name — but the grammar keeps them in the node text, `declaredPackage`
joined them verbatim and `resolveKotlinImport` required an exact match, so the
sole real candidate was rejected and `GET /right` was lost. Every identifier
that becomes a map key or a lookup name is now read through
`unquoteKotlinIdentifier`: package segments, import specifiers and aliases,
declaration and member names, and references. Both directions matter — an import
may quote a segment the declaration spells plainly, and the reverse — and a
KEYWORD segment, which can only be spelled quoted, still folds.

Comment correction. The previous commit's note claimed "Sibling INITIALIZERS are
unaffected (they go through the scope chain above); only a bare reference from a
route annotation can land on the wrong companion." That is false, and the
`/comp/m` case above is the counterexample: a top-level initializer has an EMPTY
scope chain, so `qualifyRef` leaves its operand bare and the file-wide companion
key answered it. The source comment now describes what the code does; the claim
also appears in the `ef402a4a` commit body, which is already published and is
left as written.

Not changed. `resolveKotlinImport` computes `declaring` — the unique in-package
file that declares the sought name — and uses it only to REJECT when two files
declare it, never to resolve. With two or more in-package candidates it falls
through to the file-name convention and returns null, dropping a case Kotlin
resolves unambiguously. Returning it would flip the pinned assertion "returns
null when the package holds two constant files and no name matches" from skip to
route (that fixture's `Paths.kt` does declare `object ApiPaths`, so `declaring`
is not null there despite the test's title), so it is left open as a follow-up
rather than traded against a skip-floor assertion.

Fixture sweep: 82 cases in both POSIX and Windows key styles. Six move, all
listed above; the other 76 are byte-identical on both key styles, including the
companion-inside-its-own-class control, the qualified-reference cases, and the
pre-existing interface-inheritance gap on a constant controller prefix, which is
unchanged and remains a separate follow-up.

* fix(group): admit backtick-quoted constants, and overlay a same-file val that imports nothing

Two gate defects, both reported by the review bot and both reproduced before
being fixed.

`isKotlinConstantFile` matched only `\w+` for a declaration's name, so a file
whose constants are backtick-quoted — `const val ` + "`ORDERS`" + ` = "/orders"` — failed both
arms and was never parsed into the repo constant map. The resolver supports
backtick identifiers everywhere else: `unquoteKotlinIdentifier` strips the
quoting at every point a name becomes a key or a lookup. So the gate was
NARROWER than the extractor, which is the one direction its arms exist to
exclude, and a cross-file reference to such a constant floored to skip.
Measured: the route emitted nothing, and emits `GET /orders` now.

The on-demand overlay in `scan` admitted the file's extraction only when it had
imports. A file declaring a top-level non-`const` `val` is already excluded from
the pre-pass map (no `const`, no `object`), so this branch is its only chance,
and an import-only test discarded exactly the constants the route needed. The
guard now matches the admission test the pre-pass itself applies.

The bot stated this second one more broadly than it holds. Measured, any import
at all masks it — a realistic Spring controller always has one — so the failure
needs all three of: a top-level non-`const` `val`, no `object` in the file, and
no imports. Narrow, but real, and the fix costs one predicate.

Verified with the differential probe: both cases go from no detection to the
correct route, and all 41 existing fixtures are byte-identical before and after.

* refactor(group): let the resolver own Kotlin enclosing-type qualification

The route caller gated kotlinEnclosingTypeNames on its own copy of
foldKotlinOperands' bare-ref predicate. That gate could not change the
result — qualifyKotlinRefInEnclosingTypes returns a dotted name unchanged —
so it only spread one rule across two modules that can drift apart.

Also corrects a trimmed comment that claimed a collection_literal never
reaches classifyPathArgument, which the non-empty branch there disproves.

* fix(group): keep unfoldable Kotlin constants as skip, not a wrong route

Record declared-but-unfoldable names so a companion or duplicate FQN cannot fall through to a foldable twin, and treat empty [] as no prefix on parsed RequestMapping arrays. Prefer the unique declaring file before package filename fallbacks so extra unfoldable files in the same package do not drop a real route.

* fix(group): preserve full paths for nested Kotlin constants (#3059)

Key nested objects and companions by their full enclosing type path so same-file, imported, and bare nested references resolve consistently.

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

* fix(group): qualify a PARTIALLY qualified Kotlin reference, not just a bare one

Both qualification points short-circuited on `name.includes('.')` — "already
carries its owner". A dotted reference carries AN owner, not necessarily its own
full one, and Kotlin resolves a partially qualified name against the enclosing
scopes exactly as it resolves a bare one.

Measured on the branch before this change:

  * `object Outer { object Inner { const val Q = "/orders" }
                    @GetMapping(Inner.Q) … }`
    emitted NOTHING. The key is `Outer.Inner.Q`; left unchanged, `Inner.Q`
    matches nothing.

  * a top-level `object ApiPaths { ORDERS = "/orders" }` beside
    `class OrderController { object ApiPaths { ORDERS = "/inner" } }`, with
    `@GetMapping(ApiPaths.ORDERS)` inside that class, emitted `/orders`.
    The compiler binds the NESTED object, so the application serves `/inner`.
    That is a wrong route, not a missing one.

  * the same defect on the initializer side: `const val ROUTE = Inner.Q + "/m"`
    inside `object Outer` emitted nothing, where Kotlin gives `/orders/m`.

Fixing only one side would leave the two halves disagreeing about what a dotted
name means, which is the asymmetry the earlier defects in this file came from,
so both move together:

  * `qualifyKotlinRefInEnclosingTypes` drops the early return. The scopes it
    walks are already qualified, so prefixing them onto whatever the reference
    spells is the whole rule.
  * `qualifyRef` splits at the last dot and prefixes the scope onto the OWNER,
    so the bare case is byte-for-byte what it was.

The allocation gate in `foldKotlinOperands` loses its `!includes('.')` clause
for the same reason. It was not merely a missed optimization: it decided the
result per OPERAND LIST, so the same `Inner.Q` folded or not depending on
whether a sibling operand happened to be bare.

Verified with the differential probe: the three cases above go from wrong or
missing to correct, and all 41 existing fixtures are byte-identical to
face59ae in both POSIX and Windows key styles.

fix(group)!: stop group sync claiming matching it never did (#3020)
* fix(group)!: remove the matching cascade that was advertised but never built

`gitnexus group create` wrote `matching.bm25_threshold` and
`matching.embedding_threshold` into every generated group.yaml, and no matcher
ever read either one. That was not the whole of it — an entire feature surface
described a BM25/embedding cascade that does not exist:

- `matching.bm25_threshold` / `matching.embedding_threshold` — parsed, persisted,
  unread
- `detect.embedding_fallback` — defaulted and templated, unread
- `MatchType` declared `'bm25' | 'embedding'`; both variants unreachable
- `SyncOptions.skipEmbeddings` — declared in sync.ts and never read
- `gitnexus group sync --skip-embeddings` — accepted, threaded through
  GroupService, ignored
- CLI help in en and zh-CN promised "Exact + BM25 only (no embedding fallback)"
- the MCP `group_sync` schema exposed `skipEmbeddings`, described as
  "Exact + BM25 only (Demo PR: same as default exact path)"

`sync.ts` imports exactly `buildProviderIndex`, `runExactMatch` and
`runWildcardMatch`, and the printed cascade has one stage. An operator whose
links do not match reaches for those thresholds first, and turning either knob
changes nothing — config that silently does nothing is how people conclude a
feature is broken.

Evidence that the cascade should be deleted rather than implemented, from a real
backend/frontend pair: of 165 consumer contracts, 149 link exactly and 16 do not.
Nine of the sixteen are third-party APIs (Google OAuth, Apple public keys,
PostHog, image annotation) with no in-group provider by construction — similarity
matching cannot recover them, it can only invent false links. Two are verb
mismatches: the frontend calls `POST /links` and `GET /links/check-exists` while
the backend declares `GET /links` and eleven other `/links/*` routes but neither
of those, so a fuzzy path match would link a POST consumer to a GET provider. The
rest are path-extraction artifacts. Roughly none of the sixteen would be
correctly recovered, and several would be actively mis-linked.

BREAKING CHANGE: `gitnexus group sync --skip-embeddings` and the MCP `group_sync`
`skipEmbeddings` parameter are removed. Both were accepted and ignored, so no
behavior changes — but a script passing the flag now fails with `unknown option`
instead of being silently misled. Existing group.yaml files keep loading: the
removed keys are simply no longer part of the schema, and a regression test pins
that a legacy config carrying all three still parses.

Closes #3006

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

* fix(group)!: honour --exact-only, drop inert --allow-stale, report every matching stage

Addresses the review findings on #3020, all of which are the same defect the PR
itself is about: group-sync surface that describes behaviour the pipeline does
not have.

`exactOnly` was inert in exactly the way `skipEmbeddings` was — declared on
`SyncOptions`, threaded through the CLI and the MCP tool, and read by nothing —
and strictly worse, because the stage it promised to suppress DOES run and DOES
write `matchType:'wildcard'` links into contracts.json and the bridge, which
`group impact` and cross-repo `trace` then traverse. It is now honoured rather
than deleted: unlike the never-built BM25/embedding stages, the stage it names
exists, so the flag describes a real choice. The substituted result is
`{ matched: [], remaining: unmatched }`, not an empty result — `wildcard.remaining`
IS `SyncResult.unmatched`, so skipping the stage has to leave its input unmatched
rather than dropping it from the count an operator reads.

`allowStale` had no such stage to gate: `syncGroup` emits no stale warning at any
point (the `checkStaleness` call lives in `groupStatus`, a different path), so it
is removed under the same rationale as `skipEmbeddings`.

`group sync` now prints every matching stage instead of `exact` alone. The old
block printed a `Matching cascade:` header and counted only exact links while the
next line reported `result.crossLinks.length` — which also includes `manifest` and
`wildcard` — so for any group with those the two numbers disagreed with nothing on
screen explaining why. Counting is an exhaustive `Record<MatchType, number>`, so a
new MatchType fails the build here instead of going silently uncounted, and reads
through `?? 0` so a legacy registry carrying a removed matchType prints an honest
count rather than `NaN`.

Also: the MCP `group_sync` description no longer omits the wildcard stage that
always runs, `exactOnly`'s description no longer refers to a "cascade", and
bench/cross-repo-trace/verify.mjs no longer generates the removed threshold keys
into a fresh group.yaml.

Tests: `sync-exact-only.test.ts` pins both directions of the gate (mutation-verified:
removing the gate, or returning `remaining: []`, both go red). `group-tools.test.ts`
pins that the MCP schema dropped `skipEmbeddings` and kept `exactOnly`.
`group-cli.test.ts` pins that both removed flags are rejected, with `--exact-only`
as an accepted-flag control. `config-parser.test.ts` now pins that legacy keys are
PRESERVED (measured, not assumed) rather than only that parsing does not throw.

The type narrowing's fallout in test files is cleared: `tsc -p tsconfig.test.json`
is 987 errors at head against 987 measured on origin/main, with the two error sets
identical — zero net, zero new, zero masked.

Verification: `tsc --noEmit` exit 0; prettier clean; eslint 0 errors (2 warnings,
both pre-existing on base); 69 test files / 1169 tests green across
test/unit/group, test/integration/group, tools, cli-i18n and cli-index-help.

* fix(group): reject malformed and retired group_sync parameters (U1)

`GroupService.groupSync` read `exactOnly` off an untyped MCP payload with
`Boolean(params.exactOnly)`. While the flag was inert that coercion was
harmless; now that it gates the wildcard matching stage, the string "false" --
a routine shape for an LLM caller emitting JSON -- is truthy, so a caller that
asked to KEEP wildcard matching got it suppressed and a registry with fewer
cross-links persisted to disk. The opposite of the request, written down.

Validate instead of coercing, at the service boundary: the MCP SDK does not
enforce a tool's advertised inputSchema and `callTool` is reachable directly,
so this method is the real gate. The validator mirrors `validateImpactMode`'s
`{ value } | { error }` shape -- the established idiom for this boundary, and
the one groupSync's other guards already return through.

Also refuse `skipEmbeddings` and `allowStale` by name. The CLI rejects them
outright because commander errors on an unknown option; the MCP path accepted
and silently dropped them, so an agent working from a cached tool schema was
never told. Removing them took away discoverability, not acceptance.

Both guards run before the group is read off disk, so a rejected call performs
no work. Every test asserts the sync did NOT run -- an error string alone
cannot distinguish "refused" from "refused but synced anyway".

The tool description gains the validation note AFTER the registryOutcome
paragraph: `tools.test.ts` slices that description by ordinal position of the
'preserved' / 'superseded' / 'no-prior-registry' literals, so appending past
all three leaves those slices intact (verified, 44/44).

tsc clean; 1039/1039 group unit tests pass.

* fix(group): record the matching stages a sync was told to skip (U2)

An `--exact-only` sync wrote a contracts.json and bridge with fewer cross-links
and nothing recorded that the wildcard stage had been suppressed by request.
`group_impact` and cross-repo `trace` read that registry as authoritative, so a
narrowed graph was indistinguishable from a complete one -- and because
`group_sync` is MCP-exposed, one agent call durably narrowed the shared answer
for every later reader with no signal at all.

Add `suppressedMatchStages` to ContractRegistry and SyncResult, following the
`unreadableRepos` tri-state end to end: absent means a registry written before
the field existed, `[]` is the measurement "this run suppressed nothing", and a
populated list names the stages. The writer always emits it, because omitting
the empty case is what made "measured, none" unreachable for `unreadableRepos`.

Two properties that are easy to get backwards, and are why the split matters:

- SyncResult carries the marker on EVERY outcome. The sync genuinely did skip
  the stage whatever happened to the file afterwards, and the CLI summary (U3)
  renders from this rather than re-deriving it from the caller's options.
- The PERSISTED registry stamps it only on the `written` outcome. The preserve
  path re-writes `{ ...prior }`, so a carried-forward registry keeps the marker
  of the sync that actually produced its contracts instead of being relabelled
  with this run's request. That holds by construction: the registry literal
  carrying the field is only reachable on the written path.

`loadContractRegistryResilient` gains an explicit line, because it rebuilds the
envelope field by field with no spread of the parsed root -- a new on-disk field
is silently dropped unless named there.

Its reader is `recordedMatchStages`, not the existing `recordedRepoList`: that
one validates `string[]`, which is right for repo names and one notch too weak
here. This repo has already retired MatchType members ('bm25', 'embedding'), so
a stale value on disk is a real shape, and dropping non-members keeps an unknown
stage name from reaching a caller typed as a live one.

Surfaced on `group_contracts` and on `group_sync`'s own return -- deliberately
kept separate from the truncated/truncationReason/riskEpistemic triple. That
triple reports limits a run hit by accident, whose remedy is to fix the repo; a
suppressed stage was asked for, and its remedy is to re-sync without the flag.
Conflating them would tell an agent to retry something that returns identically.

tsc clean; 1043/1043 group unit tests pass.

* fix(group): name a skipped matching stage as skipped, and pin it (U3, U4)

Two facts were printing as the same line. `wildcard: 0 cross-links` meant both
"the stage ran and matched nothing" and "the stage never ran because you passed
--exact-only" -- the same conflation this summary block was introduced to remove
one line up, reintroduced by the flag that made the block necessary.

Render a suppressed stage as `skipped (--exact-only)`, driven by the sync's own
`suppressedMatchStages` rather than by `opts.exactOnly`. The renderer reports
what the sync did, not what the caller asked for, so it stays correct on the
outcomes where the run ended without writing a registry -- which is where the
summary is least legible and a re-derivation from the options would have been
wrong.

Also drops the `?? 0` fallback and the comment justifying it. The comment
claimed a legacy registry could carry a retired matchType into this loop. It
cannot: `syncGroup` returns a freshly computed `crossLinks` array on every
outcome, and even on the preserve path the prior links go to disk while the
fresh array is returned. The code was harmless; the stated reason was false, and
a comment that explains an unreachable path is worse than no comment.

U4 pins both halves through the CLI. A manifest fixture is sufficient: the stage
counts must sum to the total on the `Wrote contracts.json (…)` line, and the
skipped rendering does not need a stage to have matched anything, because
--exact-only records the suppression whatever the fixture holds. That is why
this coverage did not need indexed gRPC/Thrift fixture repos.

Verified by mutation, not assertion: removing the skipped-rendering branch turns
`names a stage it was told to skip as skipped` red and leaves the other 22
green. A control case pins the opposite direction -- the same group without the
flag still reports the stage as zero -- so `skipped` cannot be printed
unconditionally and pass.

U3 and U4 land together: the test has no value without the renderer, so one
commit keeps a revert clean. Both depend on U2, which introduced the field they
read.

tsc clean; 1066/1066 across the group unit and CLI integration suites.

* fix(group): make every description of --exact-only match what it does (U5)

Two descriptions this branch wrote or touched still misstated behavior.

The MCP `exactOnly` description carries "Manifest links still apply." The CLI
help and both locale strings, rewritten in the same commit, omit it -- so the
surface most operators read understated what still runs. Manifest cross-links
are computed before the gate and are genuinely unaffected by the flag, so the
caveat is the accurate half and the CLI now says it too.

The `group_sync` tool description opened with "extract HTTP contracts". That
clause was carried forward byte-identical while only the trailing cross-linking
half was rewritten, and it is wrong: the detect config has six non-HTTP
extraction toggles, and this branch's own new test fixture is Thrift.

`help-i18n.ts` is deliberately untouched. It maps an option to its translation
key and that key already exists; only the commander string and the two locale
values carry text, so a text-only change does not reach it.

The tool-description edit sits ahead of the registryOutcome paragraph, leaving
the relative order of the 'preserved' / 'superseded' / 'no-prior-registry'
literals intact -- `tools.test.ts` slices that description by their positions.

tsc clean; 64/64 across the locale-parity, help-registration, tool-schema and
group-tool suites.

* fix(group)!: remove max_candidates_per_step and shared_libs (U6)

Both keys were declared, defaulted, written into every generated group.yaml,
and read by nothing -- the same three-station dead surface this PR removed for
bm25_threshold, embedding_threshold and detect.embedding_fallback. Every other
DetectConfig field gates a real extractor in sync.ts; shared_libs gates nothing,
because 'lib' contracts come only from the operator-declared manifest extractor.
MatchingConfig reaches matching.ts solely through buildNoisyContractFilter,
which reads exclude_links_paths and exclude_links_param_only_paths and nothing
else.

Existing group.yaml files keep loading and keep their keys. parseGroupConfig
spreads the raw block over its defaults, so a key the schema no longer knows
about survives into the returned config -- which matters because `group add` and
`group remove` round-trip the operator's file through loadGroupConfig ->
yaml.dump -> write, so anything the parser dropped would be deleted from their
checked-in file. The legacy-config test now pins both keys in the same cast form
as its three siblings, and the fixture carries shared_libs so that assertion is
not vacuous.

Two stations that are easy to miss and are swept here:

- gitnexus/bench/cross-repo-trace/verify.mjs GENERATES a fresh group.yaml. It is
  not a preserve-path fixture, so "leave YAML fixtures alone" does not cover it;
  the repo has two generators and both are updated. It is a .mjs file outside
  tsconfig's include, so no type gate would have caught it.
- config-parser.test.ts asserted the removed default at runtime, which vitest
  DOES run. That assertion is gone from the defaults case (the key no longer has
  a default) and re-formed as a preserve assertion in the legacy case.

Verification gate, corrected: "zero net new errors against origin/main" would
have measured the whole branch delta and been red through no fault of this
commit. Measured instead against the branch tip immediately before it --
tsc -p tsconfig.test.json --noEmit reports 989 before and 989 after. Twenty-four
typed-literal sites across ten test files, none of them CI-gated, plus the two
runtime sites above which are.

Note the deliberate side effect: removing a key from the defaults also stops the
group add round-trip from re-adding it to a file that never carried it. Nothing
in src reads either key, so no behavior changes.

BREAKING CHANGE: `matching.max_candidates_per_step` and `detect.shared_libs` are
no longer part of the group.yaml schema and are no longer written into generated
templates. Existing files carrying them continue to parse and retain them.

src tsc clean; 1189/1189 across the group unit, group integration, locale-parity,
help-registration and tool-schema suites.

* docs(group): map PR #3020 review findings to the commits that close them

Retitles the ledger to hold one section per reviewed PR and adds #3020's ten
findings. Two things are stated rather than claimed away: `abda0d041` closes
three findings because they are one code block plus the test that pins it, and
the suppressed-stage marker is a coupled set because the renderer consumes the
field the earlier commit introduces.

Also records what is NOT closed here -- the PR description's false claim about
`max_candidates_per_step` lives outside this branch.

* refactor(group): apply simplify-pass findings

Four cleanup agents (reuse, simplification, efficiency, altitude) over this
run's diff. Efficiency was clean. The rest found five things worth fixing, two
of which were real gaps rather than style.

`recordedMatchStages` filtered unknown values instead of rejecting the list.
That inverted the tri-state on the one field built to prevent exactly this
conflation: a stale `['bm25']` -- the scenario its own comment cites as the
motivation -- survived as `[]`, which on this field MEANS "measured, nothing was
suppressed". A confident clean answer manufactured from a value we could not
read. Now all-or-nothing, matching `recordedRepoList`.

`gitnexus group contracts` showed nothing after an exact-only sync. The human
renderer destructures a fixed field list and gates its incompleteness warning on
`truncated`, so the marker reached the MCP payload and the JSON output but not
the listing an operator actually reads. It now warns, separately from the
`truncated` warning, because the remedies differ: one says fix the repo, this
one says re-run without the flag.

`verbose` was still coerced with `Boolean()` in the same call whose tool
description this branch changed to promise "PARAMETERS ARE VALIDATED". Validated
now, and added to the tool schema -- it was read by the backend and advertised
nowhere.

Reuse: the thrift wildcard-matchable pair existed twice, near-verbatim, in
`sync-exact-only` and `registry-suppressed-stages`. Both now call a shared
`makeWildcardPair` fixture, so the shape `runWildcardMatch` fires on is defined
once.

Simplification: dropped a `Set` built per sync over a list that only ever holds
zero or one entries; iterating `Object.keys(STAGE_COUNTS) as MatchType[]` also
keeps the exhaustiveness the `Record` was built for, which `Object.entries` had
discarded.

Deliberately not done, with reasons: a schema-driven unknown-parameter layer at
the MCP chokepoint (five parameters are read by backends and declared in no
schema, so a strict layer rejects working calls today, and it cannot produce the
"was removed" message finding 3 is about); folding the marker into
`GROUP_IMPACT_TRUNCATION_REASONS` (reverses a recorded plan decision and the
bridge scope is an open question for the maintainer); a per-stage suppression
cause `Record` (no second suppressor exists -- speculative); collapsing the six
`detect` extractor branches into a table (a real generalization, but a refactor
outside this diff); and converging an untouched pre-existing CLI test onto the
new manifest helper (it captures a value the helper does not return, so the
change risks more than the duplication costs).

tsc clean; eslint 0 errors (1 pre-existing warning); 1085/1085.

* docs(group): remove REVIEW-FINDINGS-MAP.md

Removes the findings-to-commits ledger from the source tree.

Note for anyone reading this in history: the file was introduced on main by
#3012 and carried that PR's findings map; this branch had appended a #3020
section. Deleting it drops both. #3012's content is recoverable with
`git show 2c0fb7753:gitnexus/src/core/group/REVIEW-FINDINGS-MAP.md`.

* fix(group): stop cross-repo impact and trace claiming a narrowed graph is complete

Closes the half of the suppressed-stage finding that was deferred. The reviewers
were right that deferring it was the weak point: the motivating harm was named
as `group_impact` and cross-repo `trace` traversing a graph missing real edges,
and those were exactly the surfaces left uncovered.

The deferral rested on an assumption that does not hold. "It is already blind to
this, so we do not make it worse" is false: `--exact-only` was inert before this
PR, so the number of narrowed registries in the world goes from zero to nonzero
exactly when this lands. The blindness was harmless only while narrowing was
impossible. And silence there is not neutral -- `cross-impact.ts` documents
`truncated: false` as an affirmative completeness claim, so those tools were
about to start asserting a complete answer over a knowingly short graph.

`suppressedMatchStages` now rides the bridge the same way `unreadableRepos`
does: persisted in meta.json (no BRIDGE_SCHEMA_VERSION bump -- meta fields have
this precedent), read back all-or-nothing, and carried across the preserve path
through `refreshPreservedBridgeMeta`'s diagnostics so a preserved bridge keeps
the marker of the sync that actually built it.

`crossRepoCompleteness` folds it in, which is what makes this one change reach
all three surfaces -- that function is by design the ONE computation behind the
truncation triple. Precedence is explicit: an unreadable or unaccounted repo
outranks a suppressed stage, because it is the more serious structural gap and
its remedy has to be the one reported.

`'suppressed-stage'` is a new member of the truncation-reason union rather than
a reuse of `'incomplete-sync'`. The earlier decision not to touch that union was
about not conflating remedies -- telling an agent to repair a repo that read
fine, for a narrowing it requested. A distinct member preserves that reasoning
while letting the answer stop claiming completeness, which is what reusing the
existing member would have destroyed.

The union's guard test did its job: adding a member failed the check that every
reason is explained on the agent-facing surface, so the impact tool description
now names this one and its distinct remedy (re-run WITHOUT the flag; nothing
failed to read).

`group status` and its CLI renderer surface it too, on the populated case only
-- absent is a registry predating the field and empty is the ordinary clean
sync; neither earns a line.

Deliberately still not done, and why: a repo-wide unknown-parameter layer for
every MCP tool. Five parameters are read by backends and declared in no schema
(`subgroupExact`, `unmatchedOnly`, `showClusters`, `showProcesses`, and
`verbose` until this branch declared it), and three tools dispatch with no
schema entry at all, so a strict layer rejects working calls until each is
reconciled. That reconciliation is the work; the layer is the cheap part. It
also cannot produce the "was removed and is no longer accepted" message the
retired-parameter guard exists to give.

* fix(group): make the suppressed-stage signal actually reach its readers

Applies the mechanical findings from the code review of the previous commit.
That commit claimed cross-repo impact and trace stop reporting a narrowed graph
as complete. Trace did; impact did not, and two operator-facing messages said
something false. Four reviewers plus the cross-model pass converged on the same
two defects, and the untested seams were exactly where they were.

`runGroupImpact` recomputed the truncation reason and hardcoded its fallback, so
it could never emit 'suppressed-stage' -- the value the previous commit added to
the union and documented in the tool description. Every narrowed-but-readable
bridge was reported as 'incomplete-sync', telling the caller to repair a repo
that read fine. It now propagates the bridge's own reason, as cross-trace.ts
already did.

The preserve path stamped this run's request onto an older bridge. When no repo
can be read the database and registry are kept from an earlier sync, so
meta.json has to keep describing that sync; instead `{ ...existing,
...diagnostics }` overwrote its marker, leaving contracts.json, meta.json and
bridge.lbug describing three different runs. Currently masked by unreadable-repo
precedence, one loosened condition from a live wrong verdict.

`group contracts` printed "the last sync did not record which repos it could
read" after any exact-only sync: truncated was set with both repo lists empty,
so the message fell through to the wrong branch. It is now gated on the reason,
not the flag. `group impact` likewise blamed the local walk for a floor the flag
caused.

The tri-state reader is now defined once, in the leaf module whose own comment
says it exists so this exact duplication cannot recur -- it had been copied into
bridge-db.ts within one commit of that comment being true.

Both agent-facing descriptions now name the field. The previous commit added it
to three payloads and documented it on none.

Tests cover what shipped green: the preserve path for both artifacts (verified
by mutation -- reintroducing the stamp turns exactly one test red), and the
reason's REACHABILITY. The existing guard only asserted each reason is
described, which is why a documented-but-unemittable value passed it.

Also corrects a comment that said the marker is deliberately not folded into the
truncation triple. True when written; false one commit later.

tsc clean; eslint 0 errors; 1163/1163 across the group unit, group integration
and tool-schema suites.

* fix(group): drop verbose from the MCP surface, fail a superseded bridge closed

Two maintainer-directed findings from the review.

verbose is removed from the group_sync MCP schema and from GroupService, and
kept on the CLI. The parameter never did what either description claimed: the
gates emit workspace-dependency discovery stats and one aggregate manifest line,
not "each cross-link". Worse, they emit them through the server's logger, which
an MCP caller cannot read at all -- so advertising it introduced precisely the
kind of knob this PR exists to delete, in the PR that deletes them. SyncOptions
keeps the field and the CLI keeps --verbose, because a CLI user really can see
that output; its help now says "Show additional sync diagnostics", which is
what it shows. It was added to the MCP schema earlier in this same PR, so there
is no published compatibility burden in taking it back out. A caller that still
sends it is ignored rather than refused: it was never a documented parameter,
and the retired-name guard is reserved for ones this tool actually withdrew.

The second fixes a split-brain the completeness work made materially worse. When
contracts.json commits and the bridge write then fails, the previous database
stays in place describing an EARLIER sync. Until now it kept vouching for
itself, so group_impact could traverse the superseded graph and call its answer
complete while group_contracts reported the advanced registry -- two public
surfaces making contradictory epistemic claims out of one sync. That was
tolerable when the disagreement was about counts. It is not, now that
suppressed-stage makes completeness a correctness property.

markBridgeProvenanceUnknown withdraws the claim without touching the database:
bridgeMetaMatchesFile already gives provenanceUnknown highest precedence and
refuses to vouch for the pair, so cross-repo answers downgrade to a floor until
a sync succeeds. Deliberately not a re-stamp -- the metadata still describes the
database it was written for, and saying otherwise recreates the mis-pairing the
preserve path avoids. Deliberately not a delete -- the old graph is still worth
having as a floor, it just stops being called complete. Best-effort, because it
runs inside a failure handler and must not replace a reported bridge failure
with an unrelated one; the warning now states which of the two happened.

Shared registry+bridge generation identity is the architectural fix and is
deliberately NOT attempted here. This is the PR-sized containment.

Verified by mutation, both directions: neutering the withdrawal turns the new
test red, and a control pins that a healthy sync does not withdraw provenance --
otherwise every successful run would report its own answers as a floor.

tsc clean; eslint 0 errors; 1185/1185.

* refactor(group): apply simplify-pass findings

Four cleanup agents over the last five commits. Efficiency was clean and traced
why: the containment helper is failure-path only, the reason ternary sits after
the fan-out loop, and the tri-state readers run once per artifact read.

The strongest finding was one the diff itself proved. `refreshPreservedBridgeMeta`
enforced the never-persisted rule for `repoListsUnreadable` and
`pairedWithDatabase` with two deletes in its own body, under a comment noting it
was the only code that read metadata and wrote it back. That held exactly as
long as there was one such caller. `markBridgeProvenanceUnknown` made it two,
and inherited nothing. The strip now lives in `writeBridgeMeta`, so every writer
gets it and no future one can forget; `pairedWithDatabase` is the dangerous one,
because persisted it tells every later reader the pair was verified when nothing
verified it.

`group impact` still printed "fan-out stopped early" whenever `truncatedRepos`
was non-empty — but the bridge's incomplete repos are unioned into that list
even when zero crossings were attempted, so a structural gap was reported as a
runtime one, with the only working remedy omitted. That is the same false-cause
shape the contract listing was re-gated for one commit ago, left live one
command over because the new reason was bolted in front of the old branch rather
than replacing the thing it branched on. Now keyed on the reason.

The `?? 'incomplete-sync'` arm in cross-impact was unreachable: reaching it
needs `truncated` true with all three of its inputs false, which
`truncated = runtimeTruncated || bridge.truncated` forbids. Flattened.

Also: a `recordedMatchStages` insert had split `crossRepoCompleteness` from its
own JSDoc; one new test was a strict subset of another; and the bridge-failure
warning interleaved concatenation with a mid-chain ternary.

The new invariant assertion was caught being VACUOUS by mutation before it
shipped — seeded with a valid repo list, `readBridgeMeta` never sets the
reader-only field, so it passed with or without the strip. The fixture now seeds
an unreadable list, and both it and the pre-existing assertion go red when the
strip is removed.

Deliberately skipped, with reasons: a shared `firstTruncated` fold over
`TruncationFields` (the right altitude, but it changes cross-trace's return
assembly and that surface separately documents a 'timeout' rung it cannot emit —
a behavior change, not a cleanup); a reason-keyed `explainFloor` helper across
all four CLI renderers (real, but a four-site refactor); narrowing the persisted
stage vocabulary to a `SuppressibleStage` alias (would be undone by the very
extension the field was modelled as a list to allow); moving `verbose` to
`logger.debug` and deleting `SyncOptions.verbose` (the maintainer explicitly
directed keeping both); and merging the two tri-state readers behind a predicate
(they are adjacent in one file now, so a tightening applies to both by
inspection — the duplication the comment warned about was cross-FILE).

tsc clean; eslint 0 errors; 1164/1164.

* fix(group): address gitnexus-check findings

Seven bot comments across two review rounds; five distinct after dedup. Four
were valid and are fixed, two were already resolved by later commits the bot
had not seen.

The validator could throw from its own error path. `JSON.stringify` is the right
renderer there — it is what distinguishes the string "false" from the boolean,
which is the entire point of the message — but it throws on a BigInt and on a
cyclic object. So a validator promising a structured `{ error }` instead
rejected, and `callTool` is reachable directly, so neither input is
hypothetical. Guarded, keeping the distinction and falling back for the shapes
that cannot serialize.

An unreadable suppression record read as "nothing was suppressed".
`recordedMatchStages` is all-or-nothing by design, so garbage collapses to
`undefined` — and the consumer treated `undefined` as an empty measurement,
throwing that safety away and reporting a registry it could not parse as
complete. Present-but-unreadable now forces the floor, while absent stays
legitimate: a registry written before the field existed has no opinion and
should not be dragged to a floor for it.

Two test-side findings, both real and both invisible to CI because
`tsconfig.json` is src-only. Three `mock.calls[0][1]` accesses did not
type-check against a zero-arg mock, and four assertions read `truncationReason`
/ `riskEpistemic` straight off `CrossRepoCompleteness`, which is a discriminated
union carrying them on one arm. Also removed a `StoredContract` import that went
dead when those fixtures moved to `makeWildcardPair`.

Worth recording: U6 set a test-config gate at 989 errors and later commits
walked it to 994 without anyone re-measuring — the bot caught three of the five.
Now 987, below the original baseline.

Already fixed, not by this commit: the preserve-path stamp the bot flagged
against 6ceac8b1f (fixed in 1fbe0dc6b) and the displaced completeness JSDoc
(fixed in 2d2ef8c47).

Both behavior fixes are mutation-verified: restoring the unguarded stringify
turns the new unserializable-value test red, and a control pins that an absent
record still reads as complete so the fails-closed change cannot pass by forcing
every registry to a floor.

fix(ingestion): ignore emitted Next.js build output, and delete the inert public/build entry (#3018)
* fix(ingestion): ignore emitted Next.js build output, and restore the dead public/build entry

`DEFAULT_IGNORE_LIST` contained `.next` — the build CACHE — but not `_next`, the
emitted OUTPUT, which are different directories. A Capacitor/Cordova shell copies
a built Next.js bundle to `<platform>/app/src/main/assets/public/_next/static/`,
where no path segment hits the list, so the walker indexed the bundle as source.
On a real mobile-wrapped Next.js app that was 256 minified chunk files, and every
`Route` node the repo produced pointed at a webpack chunk rather than at source.

The filename heuristics did not catch them either: they match `.bundle.`,
`.chunk.`, `.generated.` and `.d.ts`, while Next.js emits hashed names like
`6862-9d1cdcb99f169a06.js`.

Separately, `'public/build'` had been sitting in `DEFAULT_IGNORE_LIST` matching
nothing at all. That set is tested one path SEGMENT at a time, and is also read
by `isHardcodedIgnoredDirectory(name)`, which receives a bare directory name —
so a slash-containing member can never compare equal to anything. Rather than
delete the entry and lose its intent, multi-segment paths now live in
`DEFAULT_IGNORED_PATH_FRAGMENTS` and are matched against the whole path, so
Remix / Laravel Mix asset output is ignored as originally intended.

A guard test pins the invariant that made the dead entry possible: no member of
the name set may contain a slash.

Measured against a production Capacitor-wrapped Next.js app (1558 JS/TS files on
disk): 256 newly ignored, none of them under `src/`, and zero files that were
previously ignored become indexed.

Closes #3007

* fix(ingestion): drop the inert public/build machinery, discriminate _next by segment, ignore _next on the web upload path

Addresses the review findings on #3018.

Remove DEFAULT_IGNORED_PATH_FRAGMENTS, hasIgnoredPathFragment and its
shouldIgnorePath branch. The mechanism was correct but unreachable: all four
of its match forms put a `/` or end-of-string on both sides of `build`, so a
fragment match strictly implies `build` is a whole segment, which the
per-segment DEFAULT_IGNORE_LIST loop already catches one branch earlier.
Measured over 768,420 generated paths: 65,506 fragment matches, 0 of them
decisive, 0 implication violations. `'public/build'` really was an inert
member of the name set, but its paths were never unignored — bare `'build'`
covered them on both sides — so the entry is deleted rather than relocated,
which is the other option #3007 offered. The slash-free guard test stays; it
is what stops the next slash-bearing entry from dying the same way.

Add negative cases pinning that `_next` matches as a whole path segment. The
previous suite could not tell a segment rule from a substring rule: replacing
the entry with `normalizedPath.includes('_next')` passed all five tests, while
eating `src/_nextgen/index.ts`.

Rename the public/build test to what it actually pins — that deleting the
inert entry changed no behavior — since it is green on both sides by design.

Add `_next` to the web upload filter's EXCLUDED_DIRS. That list is the live
browser ingestion path (RepoAnalyzer -> filterRepoFiles -> /api/analyze/upload)
and had `.next` but not `_next`, so a Capacitor-wrapped Next.js app uploaded
its entire minified tree against the server's 20000-file / 250MB caps for
files the analyzer then discards.

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

* test(ignore-service): make the single-component set guards able to fail

The slash-free guard added for #3007 could not fail. It selected entry lines
with startsWith("'") and read only the first quoted token per line, so
'public/build' could return as a backtick string, behind an inline block
comment, as a second entry on an existing line, or via .add() and every test
stayed green. Prettier and eslint miss the backtick and inline-comment forms
too, so CI did not catch them either.

U1: remove the duplicate '.serverless' entry so the set can be pinned to one
exact number. A Set discarded it, so no ignore behaviour changes.

U2/U3: replace the line-based parser with a shared single-pass scanner in
test/helpers/ignore-set-source.ts, and extend the guard from DEFAULT_IGNORE_LIST
to IGNORED_FILES, ROOT_ARTIFACT_DIRECTORIES and IGNORED_EXTENSIONS, which share
the same single-component match contract.

The scanner tracks string and comment state together because neither can be
removed first: the ignore-list comments quote paths and carry an apostrophe, so
matching literals before stripping comments yields phantom slash-bearing
entries; and a glob string containing a comment-open sequence makes regex
comment-stripping swallow the closing bracket. Only a single pass is correct in
both directions.

Counts are pinned exactly rather than floored — a floor cannot protect a
two-member set and hides a partial parse. Shapes a source parser cannot resolve
(spread, interpolation, concatenation, later .add) now throw instead of quietly
reporting fewer members, and the parsed names are cross-checked against
isHardcodedIgnoredDirectory so parser drift fails without exporting the set.

Verified by mutation: all six fail-open spellings now turn the suite red;
187 tests pass, tsc clean.

* test(ignore-service): pin that _next prunes the directory, not just its files

Every measured benefit of ignoring _next comes from never enumerating the
bundle tree, and no file list can observe that: anything under _next is
rejected whether the walk pruned the directory or descended and rejected each
file. childrenIgnored is the only observation that separates them.

The existing build-output tests all call shouldIgnorePath, the leaf predicate,
so a refactor moving _next to a shouldIgnorePath-only rule would keep them green
while silently restoring the full walk. These assertions close that.

Also pins that _next matches as a whole segment (_nextgen and my_next are still
walked), and that the `!_next/` negation recovers the directory at any depth —
the bare form is the one that works, since `!_next/**` alone never gets tested:
childrenIgnored prunes the directory before any descendant pattern is reached.

Placed in the .gitnexusignore-negation describe block, which owns mkPath and the
tmpdir fixture and is registered in scripts/cross-platform-tests.ts.

Verified by mutation: disabling only the pruning branch in childrenIgnored leaves
the build-output suite at 26/26 green and turns these assertions red.

* test(ignore-service): guard the twin build-output ignore lists against drift

_next now lives in two lists in two packages — the analyzer's DEFAULT_IGNORE_LIST
and the browser upload filter's EXCLUDED_DIRS — with nothing tying them
together. This is the seventh twin-list pair in this repo; the header of
receiver-twin-list-drift.test.ts records that the previous ones each shipped a
bug when one side moved.

Containment runs web -> CLI only, and that is the load-bearing direction: the
browser filter decides what the server ever sees, and it reads no
.gitnexusignore, so a name it drops that the analyzer would have indexed is
silent source loss with no recovery. The reverse is not an error — the analyzer
prunes far more aggressively than an upload needs to.

.gitnexus is the one exemption and has a mechanism: the walker passes
dot: false to glob, so it never enumerates dot-directories. Asserted in both
directions so re-adding it to the CLI list or dropping it from the web list
both fail.

Both sides are source-parsed through the shared helper. DEFAULT_IGNORE_LIST is
module-private, and no test in this package imports across the package boundary
— every cross-package precedent reads source instead.

Also corrects the documentation this PR's comments got wrong: the guard test is
cited by path rather than as "below", the unreproducible per-repo percentage is
gone, the reason _next is deliberately unanchored is recorded next to the entry
(no <web-root>/_next form matches a root-level _next/static/…), and the upload
filter now states that it consults no repository ignore rules — so unlike the
CLI, a negation cannot recover what it drops.

Verified by mutation: a web-only addition and a CLI removal each turn the guard
red. 194 targeted tests pass; tsc clean in both packages.

* refactor(test): read the ignore sets with the TypeScript parser, not a hand-rolled scanner

The guards read ignore-service.ts as source because the sets are module-private.
The first pass hand-rolled a character scanner to do it, and the repo already
vendors the right tool: ts.createSourceFile, used this way in literal-collectors,
query-determinism-guard, cli-index-help and group/sync-partial-extraction.

The scanner had two silent gaps a real parser does not have:

- It rejected `${` by substring, but template literals were consumed whole, so
  that branch could never fire and an interpolated member was accepted as a
  literal — the exact under-report the file refused to allow.
- It took the first `[` after the marker, which on a type-annotated declaration
  (`readonly string[] = ...`) is the annotation's empty pair. It returned [] with
  no throw, which would make every assertion in a suite vacuously true. This is
  the hazard receiver-twin-list-drift.test.ts documents having hit.

Reading the declaration node removes both, along with the comment-vs-string
ordering problem that motivated the scanner: a parser cannot mistake a comment
for a string or a glob's `/*` for a comment-open.

Also drops the four pinned exact counts. They were a ratchet — these sets are
edited by unrelated PRs, each of which would have failed a count assertion about
nothing it touched — and with a real parser the partial-parse hazard they existed
to catch cannot happen silently: a member that is not a plain string literal
throws.

Markers collapse to set names, and the duplicated path-resolution boilerplate
moves into the helper the two suites already share.

Net 187 deletions against 123 insertions. Verified by mutation: backtick,
inline comment, same-line, double-quote, duplicate, interpolation, spread and
runtime .add() are all caught; a type-annotated declaration now reads correctly
instead of returning empty. 194 tests pass, tsc clean.

fix(group): stop reporting what could not be measured as a measurement of zero (#3012)
* fix: surface unreadable group indexes and escape raw NUL bytes in source

Two independent diagnostics failures, both of which turn a real error into a
confident, benign-looking answer.

**Unreadable member repos (#3011).** `syncGroup` wrapped `initLbug` plus all
contract extraction for each member in a bare `catch {}` that pushed the repo
onto `missingRepos` and discarded the error. A LadybugDB storage-version
mismatch therefore surfaced as "repo not found", `group sync` printed
`0 contracts, 0 cross-links` and exited 0, and the existing contracts.json was
overwritten with an empty registry. The two states need different answers from
the operator — a missing repo must be indexed, an unreadable one is usually
version skew or a lock — so they are now separate:

- the caught error is logged with the repo, group path and lbug path
- `unreadableRepos` is tracked alongside `missingRepos` on `SyncResult`,
  persisted (optionally, so older registries still parse) on `ContractRegistry`,
  and threaded through `GroupService` sync/status
- `group sync` reports both before the cascade counts, since an unread repo is
  the likely explanation for a small or empty count
- `group status` reports unreadable repos separately; calling them "missing"
  actively misdescribed them
- when EVERY configured repo fails to open, the write is skipped: an extraction
  that read nothing is not evidence the group has no contracts, and replacing a
  good registry with an empty one loses data while reporting success

**Raw NUL bytes (#3010).** `sync.ts` and `free-call-fallback.ts` each used a NUL
as a join delimiter, written as a literal 0x00 instead of `\0`. Identical at
runtime, but it makes the file test as binary: `file(1)` reports `data`, ugrep
returns empty with exit 1 — indistinguishable from "no match", with no message —
and BSD grep replaces matching lines with "Binary file ... matches". A search
that should hit comes back as a confident "not present". Both now use the escape,
and a unit test fails on any raw control byte in src/ so it cannot silently
return.

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

* test(hygiene): guard every tracked source file against a raw NUL, not just src/

The guard added with the NUL escapes only scanned gitnexus/src for .ts/.tsx.
Neither prior recurrence of this defect in this repo was in that scope:
b620773b1 was gitnexus/bench/cpp-qualified-ns/measure.mjs and 38d737bb5 was a
fixture under gitnexus/test. A guard that cannot see where the bug has actually
landed twice is not a guard.

Drive the file list from `git ls-files` at the repository root over
.ts/.tsx/.js/.jsx/.mjs/.cjs/.mts/.cts — 2483 files instead of 828 — and split
the byte class, which is the part that matters:

  - 0x00 is a hard failure repo-wide. It is the byte git's binary heuristic
    keys on, so it is the one that costs a file its diff (and, on the base side
    of a PR, its inline-comment anchors and its three-way merge).
  - The wider C0 class stays scoped to gitnexus/src. A repo-wide scan finds
    exactly one hit, test/unit/logger.test.ts:146, and that 0x1b is a
    legitimate ANSI-escape fixture that is the subject of the test. Widening
    this half would go red on day one.

Read Buffers and scan bytes instead of decoding each file to latin1, through a
bounded read pool: 1.5 s for 2483 files, against 8-21 s previously for 828.

Add a negative fixture — a planted 0x00 and 0x1b run through the same scanning
helper — so a future refactor of the collector cannot leave a permanently green
guard, plus an assertion that the collected set still reaches bench/, test/ and
.mjs, which goes red if the scope is ever narrowed back.

* fix(group): report a cross-repo impact built from an incomplete bridge as truncated

When a sync cannot read a member repo, that repo's contracts and every
cross-link touching them are simply absent from bridge.lbug. Nothing in the
impact walk could notice: the only incompleteness channel on a
GroupImpactResult is truncationFields(), which is driven by fan-out state
(truncatedRepos / localPartial / fanoutTimedOut), and a repo missing from the
bridge sets none of them.

So `group impact` on a symbol whose one downstream consumer lives in an
unreadable repo returned `{ cross: [], truncated: false }` — "complete: nothing
in another repo depends on this". That is a wrong answer, not an empty one, for
a tool an agent uses to license a delete or a rename.

BridgeMeta now records unreadableRepos alongside missingRepos, writeBridge
persists it when non-empty, and runGroupImpact folds a non-empty
unreadableRepos ∪ missingRepos into truncated / riskEpistemic: 'lower-bound',
naming the repos in truncatedRepos.

The reason is a new 'incomplete-sync' rather than the existing 'partial'
because the remedy differs: 'timeout' and 'partial' are runtime limits the same
query can clear on a retry, while this one clears only when `gitnexus group
sync` succeeds. Runtime limits still take precedence when both apply, since
those are what the caller can act on immediately.

The risk VALUE is never clamped down — mergeRisk is monotone in the traversed
crossing count, so an incomplete bridge can only under-report. Marking the floor
is what makes that legible.

Both shape changes are additive and optional, so a bridge written before this
still reads.

Review follow-ups to the unreadable-repo diagnostics. Every item below is a

1. The CLI announced a write it did not perform. `group sync` printed "Wrote
   contracts.json (0 contracts, 0 cross-links)" unconditionally, including on
   the path that deliberately left the file alone. SyncResult now carries
   registryOutcome ('written' | 'preserved' | 'not-attempted'), the CLI prints
   from it, and group_sync returns it so an agent that calls group_sync then
   group_contracts can tell why the counts disagree.

2. Refusing to write anything on total failure threw away the diagnostic
   describing the run that just happened. `group status` reads contracts.json
   from disk, so the operator who saw the sync fail and ran status to find out
   why read the PREVIOUS sync's file: no unreadable list, an old lastSync, a
   healthy-looking group — or worse, the previous run's unreadable list
   presented as this one's. The skip is now targeted: contracts, crossLinks,
   repoSnapshots and generatedAt carry forward verbatim, only missingRepos and
   unreadableRepos are refreshed. generatedAt stays put because it dates the
   contracts, which are still the previous run's. With no prior file, or an
   unparseable one, nothing is written at all.

3. Per-repo extraction is now all-or-nothing. Extractors run in sequence and
   any one can throw; appending each one's results straight to autoContracts
   meant a repo whose HTTP extractor succeeded and whose gRPC extractor then
   failed contributed a partial set to the registry, while the same run told
   the operator that repo's "contracts are omitted from this sync".

4. readRegistry gains an opt-in strict mode, and syncGroup uses it. The lenient
   `catch { return []; }` converted "I could not read the registry" into "no
   repo is registered": every configured repo then resolved to MISSING, the
   total-failure guard stayed off (it needs a load error), and a good
   contracts.json was replaced by an empty one at exit 0. That is an unreadable
   condition reported as missing, one frame above the code this branch fixes.
   The default stays lenient for the other nine callers; ENOENT stays lenient
   in both modes.

5. Absence of unreadableRepos keeps meaning "not recorded". The loader spreads
   the key in only when present instead of defaulting to [], and getStatus
   passes undefined through, so a legacy registry no longer reads as "the last
   sync found none unreadable". getStatus also gates both list fields on
   Array.isArray: it reads through readContractRegistry, which is a bare
   JSON.parse cast, so a corrupt string in either slot used to reach
   cli/group.ts and die in .join(', ') — the command whose job is explaining an
   unreadable thing, crashing on one.

6. Smaller, same theme: the per-repo warning passes the Error itself rather
   than err.message, so pino keeps the stack; the total-failure warning no
   longer fires on a dry run, where it described a file the call was never
   going to touch and which need not exist; the status table's MISSING legend
   stops re-conflating the two states; the sync warning drops its
   GITNEXUS_LOG_LEVEL=warn hint, which would only have suppressed output (pino
   emits warn at the default info level, so the reason was already printed);
   and the group_sync tool description and its idempotency comment now describe
   what the tool actually does.

Testing. The original four cases could not see the change they were named
after. Mutation testing showed two survivors: dropping the ===
configuredRepoCount conjunct, which turns "every repo failed" into "any repo
failed" and would silently freeze contracts.json for a group where one of five
repos is skewed; and deleting both logger.warn calls, the stated purpose of the
change. Both survived because every case configured exactly one repo and
nothing read the log. There is now a two-repo case running the real per-repo
loop, an all-missing case, a _captureLogger assertion on the level 40 record,
partial-extraction cases, and strict-read cases. All five mutants are killed,
each by exactly one test.

* fix(group): tighten the registry list gates and stop naming a truncation reason on complete results

Three follow-ups from the check bot's pass over the previous commits.

1. `detect.includes` was missing from both group-sync test fixtures, so they did
   not satisfy the `GroupConfig` they claim to construct. It went unnoticed
   because `tsconfig.json` is src-only; `tsconfig.test.json` reports it. The
   older of the two fixtures carried the gap in from the original commit.

2. `runGroupImpact` named its truncation reason in a variable computed before
   the truncated check, so on a fully complete result the variable read
   'incomplete-sync'. `truncationFields` discards the reason when `truncated` is
   false, so nothing surfaced — but a value that is wrong whenever it is unused
   is a trap for the next reader. Computed inline at the one call site that can
   consult it, which is also how the neighbouring call sites are written.

3. `Array.isArray` alone let a corrupt registry through. `['app/backend']` and
   `[{repo:'x'}]` are both arrays, and only the second reaches `cli/group.ts`'s
   `.join(', ')` — as `[object Object]`, a measurement the operator can read but
   cannot act on. Both readers now go through one `recordedRepoList` helper that
   requires an array of strings; anything else is "not recorded", the same as
   absent. Two more rows in the corrupt-value table cover it.

* fix(group): keep readRegistry's signature, and stop describing unreadableRepos as index-only

Two items from the check bot's blocking pass.

1. `readRegistry` gained an optional `opts` parameter last commit. That is
   source-compatible — every zero-argument call still compiles and behaves
   identically — but the contract check treats any parameter-list change on a
   symbol with outside callers as a break, and it is right that the safest
   version of this change touches that signature not at all. The strict read is
   now its own export, `readRegistryStrict()`, over a shared private body.
   `readRegistry()` is byte-identical to what it was; `syncGroup` is the only
   caller of the strict one, and the mode is legible at the call site instead of
   hiding in an options bag.

2. `unreadableRepos` is described everywhere as "the index could not be opened".
   That was accurate before this branch and is not now: making per-repo
   extraction all-or-nothing means a repo also lands there when an extractor
   throws partway with the index open fine. The two belong in one bucket
   because the consequence is one thing — none of that repo's contracts are in
   this sync — but the docs have to say so, or an operator reads `unreadableRepos`
   as a storage diagnosis and goes looking at LadybugDB for an extractor bug.
   Corrected on `ContractRegistry`, `BridgeMeta`, `SyncResult`, the `group_sync`
   tool description, and the `group sync` console output, which now says
   "Could not extract contracts from" rather than "Could not read the index for".

* fix(cli): stop calling an unreadable registry an old one in group status

`getStatus` reports `unreadableRepos` as `undefined` for two different reasons:
the field is genuinely absent, or it held something that was not a list of repo
paths and the shape gate declined to guess. The status line named only the
first — "registry predates this field" — so a corrupt value read as a merely
old registry.

That is the same shape of wrong answer this command exists to stop giving: a
condition we could not read, presented as a benign one we understand. The line
now names both, and asks for a sync either way, which is the fix in both cases.

* fix(group): close the three fail-open paths left on the safety boundaries

Follow-ups from the re-review of 31c2b6e81. All three of its blocking findings
reproduce; each is a place where unknown state still resolved to a confident
benign answer, which is the one thing this branch exists to stop.

1. Strict registry reading accepted malformed rows. `[{}]` is a JSON array, so
   it passed the shape check: every configured repo then failed to resolve into
   `missingRepos`, none produced a load ERROR, the total-failure guard stayed
   off, and a good contracts.json was replaced with an empty one at exit 0 —
   the same fail-open the strict mode was added to close, one level down from
   the file to the rows inside it. Strict mode now requires `name`, `path` and
   `storagePath` on every row and rejects the WHOLE registry if any row fails.
   Rejecting rather than filtering is the point: dropping bad rows would report
   the repos they name as unregistered, which is the same wrong answer again.
   `indexedAt` / `lastCommit` are deliberately not required — callers already
   default them, so demanding them would trade a fail-open for a fail-shut on a
   legitimate legacy registry.

2. A failed bridge publication could make impact look complete. `writeBridge`
   swaps `bridge.lbug` and writes `meta.json` as two operations, and this branch
   made that meta load-bearing: `runGroupImpact` derives its truncation fields
   from it. A sync interrupted between the two steps therefore left a NEW bridge
   beside the PREVIOUS sync's metadata, and an impact query read that as
   "complete". Fixed from both ends. The write path removes the old meta before
   the swap, so the window leaves metadata ABSENT rather than stale. The read
   path treats absent-or-unparseable meta (`version: 0`) as unknown provenance
   and reports a floor, which also covers the caught `writeBridge` failure in
   `syncGroup`. Over-reporting truncation on a bridge that is actually fine is
   the safe direction, and the next successful sync clears it.

3. `preserved` was returned when there was nothing to preserve. On a group's
   first all-unreadable sync the outcome was set before the prior registry was
   read, so the CLI told an operator "the contracts from the previous sync are
   preserved" about a file that had never existed. Split out as
   `no-prior-registry`, with its own console message.

Also widened the NUL guard to the source languages it claimed to cover. The
commit that added it said "every tracked source file" while the collector
stopped at the JS/TS family, so a raw NUL in tracked Python, Java, Go, Rust,
C/C++, Ruby, PHP, Kotlin, Swift, C# or shell would still have turned those files
binary unnoticed. Measured before widening: 2315 non-JS tracked source files,
zero hits, so this was an unforced gap rather than a tradeoff. A planted `.py`
fixture and a collector-coverage assertion keep it honest.

Every fix is mutation-verified: reverting each one individually turns its own
tests red (3, 2, 2, 1 and 1 failures respectively), and all pass together.

* fix(group): record the empty unreadable measurement instead of dropping it

Both writers omitted `unreadableRepos` when it was empty, which made the
tri-state this branch introduced unreachable in its most common case.

`ContractRegistry.unreadableRepos` is optional on the TYPE so a registry written
before the field existed still parses, and absence there means "not recorded".
But a sync that read every repo successfully HAS measured it, and `[]` is that
measurement. Dropping it collapsed "measured, none" into "never recorded", so
after every clean sync `gitnexus group status` printed

    Last sync unreadable repos: not recorded
    (the registry predates this field, or its value could not be read)
    Re-run `gitnexus group sync` to record it.

about the sync that had just succeeded. The distinction is only worth having if
the writer commits to it, so both `contracts.json` and the bridge's `meta.json`
now record the field whenever the sync supplied it, `[]` included.

The check bot found this on the bridge writer and attributed the consequence to
`group status`. The consequence is real but it is not the bridge's: `getStatus`
reads `contracts.json` and never touches `BridgeMeta`, whose only consumer is
`runGroupImpact` — where absent and empty are already equivalent. So the
user-visible half was in the registry writer, one file over from where it was
reported, and both are fixed.

Also fills in `DetectConfig.includes` (and `workspace_deps`) across the group
test fixtures that predate those fields. These are pre-existing on main and are
a no-op at runtime — `undefined` and `false` are both falsy at the gate — but
they are the same defect the bot flagged as an error in the new fixtures, and
`tsconfig.test.json` reported eleven of them. That file is not in CI, which is
why they survived; the group tree is now clean of them.

* test(group): stop two bridge-metadata tests claiming coverage they do not have

Both were named for the swap window and neither injects a swap failure.

"drops the previous meta.json before swapping the database file" runs two
successful writeBridge calls. Its assertions hold with the removal in either
position, because writeBridge overwrites meta.json at the end regardless — so
it cannot pin the ordering it is named for. Renamed to what it does cover, the
successful-rebuild replacement, with the limit stated in the body rather than
left for the next reader to discover.

"leaves NO meta.json when the swap fails partway" removes the file by hand
after a successful write, so it exercises readBridgeMeta's missing-file
contract, not writeBridge. That contract is worth pinning on its own — version 0
is the signal runGroupImpact fails closed on — so the test stays, under a name
that says so.

The ordering itself is pinned in bridge-meta-swap-window.test.ts, which mocks
retryRename to throw on the bridge.lbug swap and asserts the previous sync's
metadata cannot survive it. Both renamed tests now point there, so the coverage
is findable from the place someone would look for it.

No production code changes.

* fix(group): pair bridge metadata to its database instead of deleting it

The previous commit closed the swap/metadata window by removing meta.json before
the database swap, so the window would fail to "absent" rather than "stale". That
was the wrong trade, and it destroyed recoverable state.

The old database's move to `.bak` sits inside a catch that swallows failures, not
just "no existing db". When that rename fails — a held read-only handle does this
on Windows, and a long-lived MCP server holds one — the failure is swallowed, the
following `tmp -> bridge.lbug` throws, and writeBridge exits with the OLD database
still in place and perfectly valid. Its metadata was already deleted. Cross-repo
impact then answers "we cannot say" for that group until some future sync
succeeds, and if the cause is a held handle or permissions there is no such sync.
A working feature, destroyed permanently to close a narrow window.

Deleting also only chose which way the window failed; it never closed it.

So destroy nothing, and make the pair self-describing instead: writeBridge stamps
the database's size and mtime into the metadata it writes, and
`bridgeMetaMatchesFile` lets a reader ask whether the two still belong together.
`runGroupImpact` treats a mismatch the same as absent metadata — provenance
unknown, report a floor. A metadata file left over from an earlier sync cannot
match a freshly renamed database, and a sync that fails before the swap leaves a
matching pair untouched. Metadata written before the stamp existed is
unverifiable rather than stale, and is accepted: failing those closed would mark
every pre-existing bridge incomplete, trading a narrow window for a repo-wide
regression.

The swap-window test now distinguishes the two failure shapes, because they want
different answers. When every rename fails the old database never moves, so the
surviving metadata still matches it and impact keeps answering from it. When only
the final rename fails the old database has already reached `.bak` and no
database is in place, so the metadata correctly matches nothing — and
`ensureBridgeReady` fails loudly on the absent file, which beats a silent floor.

Mutation-verified: reinstating the delete, neutering the pairing check, and
dropping the stamp each turn 2, 3 and 3 tests red respectively.

* chore: keep TypeScript diffs readable after a NUL leaves the tree

Git decides a pair is binary when EITHER blob carries a NUL, and it only
sniffs the first 8000 bytes. `gitnexus/src/core/group/sync.ts` carried one
at byte 5132 on main. This branch removes it, but the base side still has
it, so the file renders as "Binary files differ" in the pull request: no
hunks, no inline comments, and no three-way merge — however clean the head
side is. A head-side byte guard cannot detect that, by construction, since
it only ever sees the working tree.

Setting the `diff` attribute stops the heuristic from hiding the change.
It does not mark the files binary, does not imply `text`, and does not
change how blobs are stored, normalized, or checked out — the root
`* text=auto eol=lf` still governs all of that. It affects diff generation
and rendering only.

Locally this turns the branch's own sync.ts diff from `Bin 17612 -> 25346
bytes` into 154 insertions and 16 deletions.

* fix(group): answer "provenance unknown" for malformed bridge metadata

`readBridgeMeta` guarded the read and the parse but not the SHAPE of what it
parsed, then cast the result. `runGroupImpact` spread both repo lists straight
into a Set, so a `meta.json` whose `missingRepos` held an object threw a
TypeError out of the entire cross-repo query — and threw it from a point after
`ensureBridgeReady` had taken the bridge lease and before the `try` whose
`finally` releases it, so every such query also leaked a refcount the cached
handle could never get back. A malformed file is a reason to answer "we cannot
say", never a reason to crash the question.

The shape gate now lives where the metadata is read, mirroring the one
`service.ts` already applies to the registry's copies of these same two lists.
Each list is judged independently: a garbage `unreadableRepos` no longer
discards a `missingRepos` that was genuinely measured. A list that was present
but unusable is dropped rather than normalized to `[]`, because an unreadable
value is not a measurement of zero — the new reader-side `repoListsUnreadable`
carries that distinction, and `runGroupImpact` folds it into the same
provenance-unknown verdict it already reaches for `version: 0` and for
metadata that does not pair with the database beside it.

A root that is not an object is closed too. `JSON.parse` succeeds on `null`,
`7` and `[]`; the first threw on `.version`, and the other two read `undefined`
and sailed through the version gate as if the bridge had been vouched for.

Both provenance values moved inside the protected region and are initialized
fail-closed, so a future throw between the lease and the walk releases rather
than wedges.

`repoListsUnreadable` is reader-side only: the sole `writeBridgeMeta` call site
builds a fresh literal, so nothing persists it and no schema version moves.

Mutation-verified: reverting the shape gate alone turns 4 tests red — the three
malformed-list scenarios plus the handle-release regression.

* fix(storage): reject registry rows that cannot identify a repo

The strict read's row gate gave `typeof v === 'string'`, and `typeof '' ===
'string'`. A row whose `name` was blank therefore passed as resolvable, then
matched nothing in `defaultResolveHandle` — putting every configured repo in
`missingRepos` and presenting an unusable registry as a clean answer about an
empty one. That is the same unreadable-as-missing fail-open the strict mode
exists to close, one level further in. A blank `storagePath` is worse than
useless: it joins to a relative `lbug` under the current directory, so the sync
opens an index that is not the repo's.

Both now have to be non-blank after trimming. `path` stays at the bare string
check, on the same reasoning that already exempts `indexedAt`/`lastCommit`:
require only what resolution depends on to IDENTIFY the repo. This gate rejects
the whole registry and the registry is machine-wide, so a field tightened past
what identification needs would let one blank value in one row break every
group sync on the machine — including groups whose repos all resolve. A blank
`path` still yields a working handle; `defaultResolveHandle` does read it, but
only for the pool id and `repoPath`, neither of which decides whether the row
names a repo.

The error now says what is actually wrong instead of naming three fields that
are all present.

Mutation-verified in both directions: dropping the trim turns the three
rejection tests red, and applying the wider fix that was considered and
declined — tightening `path` too — turns exactly the counter-case red, so that
test genuinely pins the narrow reading rather than passing either way.

* fix(group): bound the per-repo contract staging append

`autoContracts.push(...repoContracts)` passes every staged contract as a
separate argument, and the engine caps how many arguments one call may take.
That cap is a function of the host's available stack, so it is a different
number on every machine — this one accepts a 125k-element spread and dies at
150k.

The spread itself is not new; what it carries is. Before staging, this line
appended a single extractor's output as it came back. Staging made it carry the
whole repo's, which is enough for a large repo to raise `RangeError: Maximum
call stack size exceeded` on the one line whose job is to commit work that just
succeeded. The throw lands in the catch below, so the sync reports a repo whose
extractors all ran cleanly as one whose index could not be read — a crash
wearing the costume of a diagnostic.

A bounded loop replaces it: the count a repo can stage is now bounded by memory
rather than by how much stack the process happened to get.

The guard is structural, not size-based, and deliberately so. A "make the
fixture big enough to crash" test passes against unfixed code on any host with
a larger stack, which is exactly the guarantee a regression gate cannot give
up. It walks the AST and locates the region by role — the `const` staging
buffer typed `StoredContract[]`, then the extractor `try` that is a direct
statement of the block declaring it — so renaming either identifier keeps it
pointed at the same code. `.apply()` is rejected alongside spread, being the
same hazard in different syntax.

Direct statements only, because `syncGroup` wraps this whole section in its own
try/finally for the lease sweep, and that ancestor reads the buffer too.
Matching any enclosing `try` pulls in the entire function body — including the
two windowed-manifest spreads, which are bounded by the window size and are not
what this fixes.

Mutation-verified in both directions: restoring the spread turns the gate red
naming that line alone; deleting a manifest-window spread, and separately
adding a third one, both leave it green.

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

* fix(group): keep unreadable repos out of manifest contracts too

Per-repo staging closed one door: a repo whose extractor threw contributes
nothing through the direct path. Deferred manifest resolution was a second
door, still open. It derives its known-repo set from the resolved-handle map,
which kept an entry for a repo the same run had already declared unreadable —
so the sync re-opened that index and resolved symbols against a database it had
just told the operator it could not read.

Deleting the handle in the catch stops the re-open, but it does not satisfy
R2 on its own: `ManifestExtractor` resolves both endpoints of a link and emits
a contract for each, and for an endpoint with no executor that contract is
still emitted with a synthetic UID. The registry ended up naming a repo the
same run reported unreadable.

So the emitted output is filtered by ENDPOINT, not by link. Dropping the whole
link would delete the healthy partner's contract as well — a repo losing its
own output because a neighbour's index would not open, which is wider than the
requirement and destroys good data to suppress bad. A cross-link is different:
it asserts something about a pair, so if either end is unreadable there is
nothing left to anchor it to, and a half-anchored link is exactly the
confident-about-what-it-could-not-read answer the registry must not give.

Deleting the handle also changed what the operator gets told, so the warning is
split. An unreadable repo IS configured; letting it fall into the "references
repos not in config.repos" branch states something false and sends the reader
to edit group.yaml for a problem only re-indexing fixes. It now gets its own
message naming what was actually omitted.

Mutation-verified four ways: reverting the endpoint filter turns three
scenarios red; the over-broad whole-link variant turns the healthy-partner
scenario red and nothing else; removing the handle delete turns the
no-re-open scenario red; and reverting the warning split turns the operator-
message scenario red. Every assertion reads the written contracts.json rather
than the in-memory result.

* refactor(group): keep readBridgeMeta's signature stable across the shape gate

The shape gate landed by widening the return type to a reader-only
`ReadBridgeMeta extends BridgeMeta`. That is source-compatible — a covariant
return, one added optional field, every existing caller unaffected, typecheck
and suite clean — but the contract check reads it as a changed signature with a
caller left behind, and blocks the merge on it. This branch already hit the
same wall on `readRegistry` and settled it the same way: leave the signature
alone and make the difference legible some other way.

So the flag moves onto `BridgeMeta` itself as an optional, documented,
never-persisted field, and `readBridgeMeta` goes back to the exact signature
its callers already compile against.

That is the better shape here anyway. The reader-only subtype would have split
the validation two ways: `openBridgeDbReadOnly` and `bridgeExists` both gate on
`meta.version`, and the normalization that comes with the gate is what stops a
`version: null` in a hand-edited meta.json from reading as `undefined` and
sailing through `version > 0` as though the bridge had been vouched for. One
type keeps all three callers behind the same guard.

Nothing persists the flag: `writeBridgeMeta`'s only caller builds a fresh
literal, so it cannot round-trip to disk.

No behavior change — pure type restructuring. 927 tests pass, typecheck clean.

* fix(group): stop treating a half-written bridge stamp as a verified match

`bridgeMetaMatchesFile` joined its two `undefined` checks with `||`, so
metadata carrying a size and no mtime — or the reverse — returned `true`, the
same answer it gives a fully verified pair.

A stamp is a PAIR. Both halves absent is the legacy shape: metadata written
before stamping existed, which cannot be verified either way and is accepted
deliberately, because failing it closed would mark every pre-existing bridge
incomplete until re-synced. Exactly one half present is not that. Something
wrote a stamp and did not finish, which is precisely the condition stamping was
added to detect — so the check handed back "verified" for the one shape that
most deserves suspicion, and a cross-repo impact query built on it would report
a confident answer about a database its metadata cannot vouch for.

The two states are now separated: neither half present accepts, exactly one
rejects as provenance-unknown, both compare against the file as before.

Found by the repository's own contract check, not by the plan.

Mutation-verified: restoring the `||` form turns both half-stamp cases red
while the legacy and fully-stamped controls stay green, so the pair genuinely
pins the distinction rather than passing either way.

* fix(group): pair unstamped bridge metadata by write order, before any open

Unstamped metadata was waved through: `bridgeMetaMatchesFile` returned "matches"
for any pair with no stamp to check, so the stale-meta-beside-a-new-database
window stayed open for every bridge written before stamping existed, and
`runGroupImpact` spent that metadata's completeness as fact.

`writeBridge` renames the database into place and writes the metadata after, so
`meta.mtime >= db.mtime` holds for any pair written together — including by
builds that predate the stamp. A database strictly newer than the metadata
beside it can only come from a swap whose metadata write did not land. That is
the fallback now. It is a heuristic on write order, not proof of provenance, and
it is wrong in two directions: a stale metadata file touched after the swap
still reads as paired, and a pair whose clock stepped backwards between the two
writes reads as unpaired. Both are recorded at the code; the second is the safe
direction. Equality counts as paired, or a coarse-granularity filesystem would
reject every legacy bridge for a reason that is about the filesystem.

The verdict is now taken in `ensureBridgeReady` BEFORE the database is opened,
and carried on the metadata rather than recomputed afterwards.

That ordering is load-bearing, not tidiness. Impact and trace both open the
bridge and only then ask about provenance, so on any platform or LadybugDB
build where a read-only open advances the file's mtime, every pre-stamp bridge
would report provenance-unknown from its first query onward — the exact
repo-wide regression this rule was chosen to avoid, arriving as a silent
downgrade rather than an error. It does not happen on Linux, which was measured.
It cannot be measured on Windows: pinning it by really opening the database
needs an in-process write→read reopen of the same bridge.lbug, which is a
documented limitation there. Rather than ship a Windows-skipped test and leave
the assumption unverified on the platform whose file semantics are most likely
to differ, the check moved ahead of the open so no platform has to be trusted.

The new guard forces the hostile case on every platform: the open is stubbed to
advance the database's mtime, and the verdict must still be "paired". It is
registered in the cross-platform list so the Windows and macOS shards run it,
and it has a control so it cannot pass vacuously.

Two existing fixtures mocked `readBridgeMeta` to return a stamped-era version
while never writing a meta.json — a state production cannot reach, since a
non-zero version can only come from a file that exists. They now write the
metadata their own mock claims to have read, rather than the helper being
loosened to accept metadata it cannot stat.

Mutation-verified twice: reverting the write-order branch turns both rejection
cases red while all four legacy-accept cases stay green, and moving the pairing
call back after the open turns the ordering guard red on its own.

* refactor(group): compute cross-repo completeness in one place

Three surfaces can return a partial cross-repo answer — impact, trace, and the
contract listing — and each decided for itself whether it was complete. Impact
carried the structured triple; trace said it in prose, if at all. An agent
reading a not-found trace had no machine-readable way to tell "there is no
path" from "there may be a path in a repo this sync could not read", which is
the difference between an answer and a floor.

`crossRepoCompleteness` is now the one computation, and its input deliberately
does not name where any of it came from. `BridgeMeta` is not in the signature
and must not be: `groupContracts` answers the same question from contracts.json
and never opens a bridge, so `version`, `repoListsUnreadable` and
`pairedWithDatabase` do not exist on that path. Each caller derives its own
`provenanceUnknown` — the bridge callers through `bridgeProvenanceUnknown`,
which stays separate for exactly that reason — and passes the boolean in.

Scope arrives as a predicate rather than a repo list or a subgroup, so
narrowing a query's scope stays a change to one argument at the call site.

The trace results now carry `truncated` / `truncationReason` / `riskEpistemic`
like impact does. `notes` is untouched; it remains an addition to the machine
channel, never the channel.

One correction to the approach as written: it said to pass the trace's two
endpoint repos as the predicate, but a destination trace declares no `to`. It
asks where a call lands, so any member may hold the answer — and an unreadable
provider repo is precisely how "no outgoing ContractLink leaves this repo"
becomes a wrong answer rather than an empty one. Filtering that path to the
`from` repo would have reintroduced the bug this unit exists to close, so it
passes every repo and a test pins it.

Two pre-existing paths become consistent with the vocabulary as a result: a
crossing-capped result now reports `truncationReason: 'partial'` alongside the
`truncated` flag it already set, and the destination path's `ambiguous` returns
now report the cap its `ok` and `not_found` siblings already reported. Both are
additive — no field is removed, and no `truncated` flips from true to false.

`truncationFields` returns a discriminated union now, so `truncationReason`
reads without a fallback on the branch where it cannot be absent.

Mutation-verified: reverting the provenance fold alone — one line in the shared
helper — turns 8 tests red across both surfaces, 2 new trace scenarios and 6
existing impact ones, which is the point of there being one helper.

* fix(group): narrow the incomplete-repo set to the query's declared scope

A subgroup-scoped impact query was marked a lower bound by repos it had
explicitly excluded. The fan-out already drops every neighbour outside the
subgroup, so those repos could not have contributed a crossing to the answer —
and a completeness marker that fires on results it does not describe is how a
caller learns to ignore the marker.

The scope is the query's DECLARED one, not the one the walk reached. An
incomplete repo's contracts are absent from the bridge by definition, so it is
never in the traversed set; filtering on what was traversed would empty the
intersection on every query and silently restore the fail-open this channel
exists to close.

Declared scope here is the subgroup PLUS the query's own repo, which the
approach did not account for. The walk starts from that repo's contracts in the
bridge, so when it is the repo the sync could not read there are no crossings
to find under any scope — and a subgroup excluding it would have turned that
vacuum into a confident "nothing depends on this", for a tool an agent uses to
license a delete. That case reported a floor before this change, so narrowing to
the subgroup alone would have been a regression. The union only ever widens the
in-scope set, so it cannot re-mark a repo the query excluded.

Membership goes through the existing `repoInSubgroup` in both clauses, `exact`
for the origin equality, rather than growing a second notion of what it means
for a repo path to be in scope.

Sound only while `MAX_SUPPORTED_CROSS_DEPTH` is 1 — at depth 2 an out-of-scope
repo can sit between two in-scope ones — and that constraint is recorded at the
intersection.

Unscoped queries are byte-for-byte unchanged: `repoInSubgroup` answers true for
an absent subgroup, so the intersection is the whole set.

Mutation-verified: restoring the unfiltered predicate turns exactly the two
scoped cases red while the unscoped control and both in-scope guards stay green.

* fix(group): keep the preserved registry and the bridge from disagreeing

A total-failure sync refreshed contracts.json's diagnostic lists and left
meta.json alone. But meta.json, not contracts.json, is where runGroupImpact
reads completeness from — so the registry said "this sync could not read
app/backend" while a cross-repo query answered `{ cross: [], truncated: false }`.
Two surfaces describing the same run, one of them wrong, and the wrong one is
the machine-readable one an agent uses to license a delete.

The preserve path now refreshes the same two fields in the metadata. The
database stays untouched: it still holds the contracts being preserved, and
rebuilding it here would be the one write that could lose them.

Refreshing metadata is not free, though, and the obvious version of it is a
fail-open. The rewrite moves meta.json's mtime to now while bridge.lbug's stays
old, so an unstamped pair whose database is NEWER than its metadata — the shape
the write-order rule exists to reject — would come out of a preserve sync
passing the check. Writing "no stamp" does not help; the write-order comparison
is exactly what the moved mtime defeats. The verdict has to be recorded in the
metadata, because the refresh cannot avoid moving the mtime.

So `provenanceUnknown` is persisted whenever the existing pair does not already
check out, the existing stamp fields are carried through verbatim rather than
dropped, and `bridgeMetaMatchesFile` rejects the marker ahead of both the stamp
and the write-order heuristic. A pair that already matched is re-stamped
instead, which also upgrades a legacy unstamped-but-paired bridge to an exact
stamp. No preserve run can increase the number of pairs that pass the check.
The marker self-clears: `writeBridge` builds fresh metadata and never sets it.

`BridgeMeta` carries two reader-side fields documented as never persisted, and
this is the first code in the repo that reads metadata and writes it back. Both
are stripped explicitly before every write. `pairedWithDatabase` is the
dangerous one — persisted, it would tell every future reader the pair had been
verified — and a test seeds both on disk to pin that neither survives.

The write is not wrapped in a catch, unlike writeBridge on the success path.
There contracts.json is canonical and already written, so a stale bridge is a
recoverable degradation; here the write IS the guard against a confident wrong
answer, and swallowing its failure would reinstate the fail-open it closes.
`writeContractRegistry` above is unguarded into the same directory for the same
reason.

A group with neither file writes nothing: `readBridgeMeta` already answers
`version: 0` for an absent file, so a written one would say what the absence
already says while inventing state for a bridge that has never existed.

Mutation-verified three ways: dropping the marker write turns 6 red including
both laundering scenarios; moving the marker check below the stamp branches
turns the unstamped-laundering case red; removing the field stripping turns the
never-persisted test red. Each restored byte-exactly and re-verified.

* fix(group): report group_contracts' completeness in the shared vocabulary

`group_contracts` returned contracts and cross-links and said nothing about
whether that listing was the whole story. An agent reading it after a sync that
could not open half the group got a confident-looking list with no way to tell
it was a floor — the same fail-open the impact path already closed, on a surface
that had no channel for the answer at all.

It now returns the registry's two diagnostic lists and the structured triple,
folded through the same helper the impact and trace surfaces use, so the three
cannot drift. The helper takes no `BridgeMeta` precisely so this path — which
reads contracts.json and never opens a bridge — can share it.

The three registry states stay distinguishable, which is the point:
  - key absent: the registry predates the field and has no opinion about which
    indexes opened, so the key is omitted rather than invented as `[]`, and the
    listing reports a floor. It cannot say which repos the sync failed to read,
    so it cannot claim to be complete.
  - key present and empty: measured, clean, not truncated.
  - key present and populated: the repos, and a floor.

`incompleteRepos` is dropped on this surface alone: both lists it derives from
are returned verbatim beside it, and a third name for the same repos is drift
waiting to happen.

The import is lazy, matching `groupImpact` and `groupTrace` in this same class.
`cross-impact.js` statically pulls the native LadybugDB binding through
`bridge-db.js`, and `service.ts` is loaded by every `gitnexus group` subcommand
including ones that touch no database.

One fix inside the same file that this unit forced: the registry loader gated
`missingRepos` with a bare `Array.isArray`, which admits `[{repo:'x'}]`. That
was inert while nothing read the list, but this change both returns it and folds
it into the completeness answer — so an unreadable value would have been printed
as a repo name and would have flipped `truncated` on garbage. It now uses the
same `recordedRepoList` gate `group status` already applies to the same field.
`missingRepos` has always been required, so unlike `unreadableRepos` it has no
"not recorded" state to preserve and an unreadable value degrades to empty.

Mutation-verified: reverting the fold alone turns 14 tests red and leaves the
control — the contract and cross-link payload this tool has always returned —
green.

* fix(cli): stop dropping group contracts' completeness fields on the way out

`group contracts --json` destructured `{ contracts, crossLinks }` from the
service payload and rebuilt an object from just those two. Everything else the
service returned was discarded on the way to stdout — so the completeness
fields the MCP tool now carries were invisible at the CLI, and the two surfaces
disagreed about the same registry.

It prints the payload whole now. A field added to the service reaches `--json`
without a matching edit here, which is the point: the re-serialized subset was
a second place that had to be remembered, and it was not.

The human-readable path gains the same signal in words. A listing built from a
sync that could not read part of the group shows counts that are a floor, not a
census, and it named neither fact. It now says so and names the repos when the
registry recorded them — and says the sync did not record which repos it could
read when it did not, because a listing that cannot say what it is missing is
still incomplete.

Mutation-verified: restoring the re-serialized subset turns the `--json` case
and the control red.

* fix(group): tell a missing registry entry apart from an unreadable one

`group status` printed MISSING for both "this repo has no row in the registry"
and "the registry itself could not be read", so an operator whose registry.json
was corrupt was told every repo was unregistered — and sent to re-register them
instead of to the one file that was actually broken.

The two are now separate. `missing` keeps its old meaning and still flags every
unusable repo, so an older consumer is unaffected; `unresolvable` is additive,
always present, and carries the reason that produced it.

This is the one caller that has to make that distinction, so it takes the
strict global-registry read. `readRegistry`'s `catch { return [] }` collapses a
malformed registry into an empty one, which is indistinguishable from a genuine
absence and is exactly what produced the wrong label. The cost is accepted
knowingly and recorded at the call site: the strict read rejects the whole
registry when any row fails to identify a repo, so one malformed row renders
every member unresolvable — including members whose own rows are fine. That is
the honest verdict, and it is reported as an unresolved state rather than a
clean one.

Choosing between the two labels needs to know whether a row exists at all,
which `registryIdentifies` answers by mirroring the two tiers the resolver
matches a bare group-config value on — registry name, case-insensitively, and
repo path. It deliberately stops short of the hashed-id and partial-name tiers:
those exist to be generous about what an operator typed, while this only picks
a label, and a looser match would relabel a genuine registry miss as an
unresolvable row — the same conflation this change removes, pointed the other
way.

The plan's third failure mode — a row that resolves but whose storage path
cannot be opened — turns out to be unreachable: `loadMeta` returns null on
every error and `checkStaleness` catches everything, so nothing after
`resolveRepo` inside the try can throw. The reachable per-repo case is
`resolveRepo` itself throwing, as it does for two registered clones sharing a
name, and that is what the tests drive end to end through the real CLI. The
code still handles the plan's case correctly if those helpers ever start
throwing.

Mutation-verified: reverting the split turns 6 unit and 2 CLI cases red while
both controls — a genuine miss, and a healthy group — stay green.

* fix(cli): say what the preserve path actually does to contracts.json

The sync summary announced "Did NOT write contracts.json" on the branch that
writes it. The preserve path rewrites the file — keeping the previous sync's
contracts and cross-links, replacing only the two diagnostic lists — so an
operator who checked the mtime and found it moved was told the opposite of what
had happened, on the command this PR exists to make legible.

It now says the previous contracts were kept and names what changed.

The no-prior-registry branch is narrowed for the same reason. It claimed
nothing at all was written, and that is no longer true either: this path still
records the run against an existing bridge's metadata. The claim is now scoped
to contracts.json, which is the file it can actually speak for.

* fix(group): stop the total-failure log promising a preservation that did not happen

The warning fired before the prior registry was read, so it could only ever
promise one of the two things that might be true — and it promised the wrong
one to every group that has never synced: "keeping the contracts from the
previous sync" about a file that does not exist. The console line for that same
run, driven by `registryOutcome`, said the opposite.

It now lives inside the branch, after the read, with one message per outcome
chosen at the point the outcome is decided. The log and the console cannot
disagree, because the same fact selects both.

Both messages keep the warn level and the two repo lists.

Mutation-verified: reverting the split turns the no-prior-registry case red
while the preserved case — whose claim was already true — stays green. The
dry-run test's log filter was also widened to the sentence both messages share,
or the new wording would have made that assertion match nothing and pass
regardless.

* fix(group): make the bridge-failure warning describe what the code guarantees

The warning after a failed `writeBridge` promised that cross-repo impact would
report `truncated` until a sync succeeded. Nothing on that path produces that
signal.

The swap is the last step: `writeBridge` builds the new database in a staging
directory and only then moves the old one aside. A failure during the build
therefore leaves the previous sync's `bridge.lbug` exactly where it was, beside
the `meta.json` stamped for it — a pair that passes `bridgeMetaMatchesFile`
with the previous run's `unreadableRepos`. The next cross-repo query answers
`truncated: false` from superseded contracts, which is the opposite of what the
operator was told to expect, and worse than being told nothing.

The warning now says what is actually true: contracts.json is intact and
canonical, the bridge was not replaced, cross-repo queries may still answer from
the previous sync's contracts, and nothing marks them as superseded.

The metadata is deliberately NOT re-stamped to make the original promise true.
That would recreate exactly the metadata/database mis-pairing the stamping on
the preserve path exists to prevent, and the comment at the warning records it.

The claim is asserted against captured log output rather than left to the state
tests. Those check which pairs match and what the preserve path writes; every
one of them stays green while this sentence reverts to promising a truncation.
An unasserted user-facing branch is the defect class this change is closing, so
it does not get to close it while remaining one.

No filesystem shape makes the real `writeBridge` fail while
`writeContractRegistry` succeeds — they write into the same directory one line
apart — so the failure is armed through a pass-through wrapper on the file's
existing mock. It delegates byte-for-byte unless a test arms it, and is reset
around the new suite.

Mutation-verified: restoring the original wording turns its own assertion red
and nothing else.

* docs(mcp): name every registry outcome group_sync can actually return

The tool's description told agents `registryOutcome` is 'written' or
'preserved'. It has a third reachable value: 'no-prior-registry', returned when
nothing could be read AND there was no previous contracts.json to carry
forward. An agent calling this tool against a group that has never synced got a
value its own tool description said did not exist, and no way to tell it apart
from the case where the previous contracts survive.

The distinction is the whole point of the value. After 'preserved' there is a
registry to read — stale, but real. After 'no-prior-registry' there is nothing
on disk at all, so a following group_contracts or group_impact has no registry
rather than an old one. Those need different responses from the caller.

'not-attempted' stays undocumented because it is unreachable through this tool,
and a guard asserts it stays that way.

The code comment above the annotations claimed the preserve path does NOT write
contracts.json. It does — it rewrites the file, keeping the previous contracts
and cross-links and refreshing only the two diagnostic lists, which the CLI's
own summary was corrected to say a few commits ago. Left alone it would have
re-seeded the same wrong claim next to the text that now states it correctly.

Mutation-verified: deleting the 'no-prior-registry' sentence turns the guard red.

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

* docs(mcp): explain structural incompleteness on the impact tool and status resource

The impact tool's GROUP MODE paragraph described one cause of truncation — the
fan-out running out of room — and left an agent to assume that was the only one.
So a `truncated: true` carrying `truncationReason: 'incomplete-sync'` read as
"retry with a smaller scope", when retrying returns the identical floor forever:
the repos are absent from the bridge itself, and only a re-sync puts them back.
The old text also said the response carries the truncation fields "when it stops
early", which is wrong for that case — `truncatedRepos` names repos even when
ZERO crossings to them were attempted, because their contracts were never in the
bridge to cross to.

The paragraph now branches on the reason and gives each its remedy: 'timeout'
and 'partial' are runtime limits where a retry or a larger budget can help;
'incomplete-sync' is structural and the remedy is `group_sync`.

The reason union is now derived from an exported `as const` array rather than
written as a bare type. A type-only union gives a guard nothing to enumerate, so
the guard has to hand-list the members — and then it passes forever the moment a
fourth is added, which is the exact regression it exists to catch. The guard
iterates the runtime array instead. Verified by appending a probe member and
watching it go red, then removing it. The resolved type is unchanged; every
importer uses `import type` and none needed an edit.

The status resource said "Group index / contract staleness" and nothing about
the distinctions its payload now carries. It explains all of them: a repo absent
from the registry versus one whose entry could not be resolved, and the
`unreadableRepos` tri-state where an ABSENT key is not an empty one — absent
means the last sync never recorded what it could read, so cross-repo answers for
that group are a floor.

The description an MCP client actually receives lives in `getResourceTemplates`,
not in the context resource's inventory line the plan pointed at. Both now carry
the vocabulary, so the two surfaces cannot disagree about the same payload.

* feat(group): serialize group syncs behind a fail-closed per-group lock

Two concurrent syncs of one group could lose one another's writes. Both read
the prior registry, both built contracts, both wrote — last writer won, and the
loser's work was gone with nothing reporting it. A group sync is long and
expensive and is exactly the operation whose lost update destroys contracts.

`syncGroup` now takes a lock for the whole persist section, acquired exactly
once. `acquireIndexLock` is not reentrant, so a second acquisition anywhere
below would deadlock the happy path rather than an edge case; `withGroupSyncLock`
has one call site and nothing inside it re-acquires.

The lock lives on a dedicated `sync-lock` directory inside the group directory,
mirroring the registry lock's dedicated directory rather than reusing the
resource's own — a lock directory that could collide with a per-repo index slot
repeats a bug the registry lock's comment already warns about.

It fails CLOSED, which is the opposite of `withRegistryLock` and deliberately
so. That one degrades to unlocked because it guards a sub-second JSON merge on
a latency-critical path; here running unprotected is the outcome the lock
exists to prevent. Three exits are covered: a timeout, an unwritable lock
directory, and the lock-free degradation the primitive performs silently.

That third exit needed a change in `index-lock.ts`, and it is the one declared
exception to keeping this work inside core/group/. `acquireIndexLock` answers a
read-only or permission-denied filesystem with a no-op handle that is
byte-identical in shape to a real one, so a caller for whom lock-free is not an
acceptable outcome could not tell the difference. It now carries an optional
`lockFree` marker. The change is additive by construction: no signature moves,
no control flow changes, nothing about when or how a lock is taken changes, and
every caller that ignores the field behaves exactly as before.

A filesystem probe inside the group module was considered and rejected on
evidence: `selectBackend` returns `socket` on Linux and Windows, where
`acquireViaSocket` never touches the filesystem and this branch cannot occur —
so a probe would refuse syncs on the two platforms that never degrade while
missing the one that does.

The timeout ceiling is a named 600s constant passed explicitly. The magnitude
matches the primitive's own analyze-sized default because a group sync is
analyze-shaped and a legitimately queued second sync must be able to wait out a
full first one. Passing it explicitly is about the override, not the magnitude:
`resolveTimeoutMs` resolves `GITNEXUS_INDEX_LOCK_TIMEOUT_MS <= 0` to Infinity,
which would turn fail-closed into a hang.

Cross-process exclusion is proved with a real spawned holder, not an in-process
mock, which cannot demonstrate the property this exists for. The lock-free
scenario pins `GITNEXUS_INDEX_LOCK_BACKEND=file` — unpinned it would pass on
two of three platforms while measuring nothing — and produces the failure by
injecting EACCES on one syscall rather than by chmod, so it runs identically on
Windows instead of being skipped there.

The CLI reports the failure through pino rather than a bare stderr write, which
this package lints as an error to keep that migration moving, and the test reads
the `msg` field rather than a raw substring — matching on the raw text would
have passed only by accident of quoting and would go green again if the line
were downgraded.

Nothing is skipped on any platform, and the test is registered for the
cross-platform shards.

Mutation-verified: removing the lock acquisition turns 6 scenarios red;
removing the lock-free rejection turns the degradation scenario red on its own.

* fix(group): make the sync-lock timeout name a cause it can establish

The fail-closed lock surfaced the primitive's own timeout message to users for
the first time, and that message says the wait was on "another gitnexus
analyze" — a cause its detection path cannot establish. It is the same
confident-about-what-it-could-not-determine claim this PR exists to remove,
inherited rather than written.

The wrapper now throws its own. It names the group, the lock directory, the
operation, and the elapsed wait, and it says plainly that nothing was written.

The holder clause branches on `holderKnown`. The socket backend exposes no owner
metadata and reports a placeholder pid of -1, so on that backend — and on the
file backend's malformed or vanished-lock timeouts — the message says the lock
stayed held but the backend cannot identify who held it, rather than printing a
pid that means nothing.

The elapsed wait is measured by the wrapper. `IndexLockTimeoutError` carries
only `holder` and `holderKnown`; the figure exists solely inside the string
being replaced, so it had to be taken rather than read.

One pre-existing assertion changed with it: the timeout case asserted
`'Timed out after 600000ms'` from the inherited text, which is precisely the
message this replaces.

Mutation-verified: restoring the inherited message turns the three assertion
cases red and leaves the control — a real acquisition that succeeds — green.

* fix(group): stop a losing sync from downgrading the one that beat it to the lock

Serializing is not ordering. Both syncs run extraction outside the critical
section, so a total-failure sync that acquires second reads the winner's fresh
registry as `prior` and rewrites it with all-unreadable lists. The lock alone
does not prevent that — it only decides who goes second, and the loser then
overwrites a healthy registry with a description of its own failure.
Deterministically, not as a rare interleave.

The guard is a compare-and-swap on the registry file's own identity: stat
before acquiring, re-stat after, and write nothing when they differ. Identity is
presence plus size, mtime and inode — `writeContractRegistry` publishes through
write-then-rename, so a real replacement always changes the inode even if size
and mtime happen to collide.

Deliberately NOT keyed on `generatedAt`, for two independent reasons. It is
stamped when the registry object is built, before the lock is acquired, so a
winner that waited would write a value older than the loser's start. And the
preserve path carries it forward verbatim by design — it dates the contracts,
not the write — so after any preserve sync it does not date the write at all,
leaving the comparison blind on exactly the pairing this guards. A file-identity
compare also needs no cross-process clock agreement.

The skip reports the existing `preserved` outcome. Nothing was written and a
prior registry was kept, which is what that value already means; a new one would
falsify the guard asserting the sync tool's description names every reachable
outcome, and would fall through the CLI's outcome chain, which has no fallback.

The bridge metadata refresh is skipped too, which the plan did not specify.
`refreshPreservedBridgeMeta` stamps THIS run's repo lists into meta.json, and
meta.json is where cross-repo impact reads completeness — so writing it would
report as unaccounted-for exactly the repos the winning sync had just accounted
for. That is the same downgrade being refused, one file over. Skipping both is
what makes `preserved` an honest answer here.

Mutation-verified: removing the after-stat and the skip turns the three decisive
cases red while both non-misfire controls stay green.

* refactor(group): run the bridge swap inside the caller's critical section

The bridge swap needed the group lock, and could not take it: `syncGroup`
already holds it when it calls `writeBridge`, and `acquireIndexLock` is not
reentrant. Acquiring inside the swap would deadlock every sync on the happy
path rather than on an edge case.

So the body splits the way this repo already splits this shape — a lock-free
`writeBridgeUnlocked` whose precondition is that the caller holds the lock, and
a thin `writeBridge` wrapper that acquires it for direct callers, mirroring
`registerRepoUnlocked` / `withRegistryLock`. `syncGroup` calls the inner one;
everything else keeps calling `writeBridge` and is now serialized by it.

`writeBridge`'s exported signature is byte-identical to before, so no caller
changed and nothing about the exported surface moved.

The precondition is enforced by a comment naming the single production call
site, which is what the existing precedent does. A type could carry it, but the
repo's own answer to this question is a comment, and diverging here would make
this the odd one out for no additional guarantee.

`refreshPreservedBridgeMeta` is deliberately left unsplit. Its one caller is
already inside the critical section and it has no test callers, so an acquiring
wrapper would be dead code standing in for a guarantee the caller already
provides — and moving the lock inside it would be the second acquisition this
change exists to avoid.

Scope: this delivers writer-writer exclusion only. The reader-side promotion of
a leftover `.bak` into place runs on ordinary reads, outside any lock, and is
not claimed here — the pairing check remains the reader's defense. Confirmed as
live behavior while writing the crash-recovery test, which asserts on file
state rather than through `bridgeExists` for exactly that reason.

One test file beyond the two the unit named had to change: a suite mocks
`bridge-db` to inject a `writeBridge` failure and exercise the bridge-write
warning. Once the sync calls `writeBridgeUnlocked`, that fault was being
injected into a function the path no longer calls, and the test went red. The
mock is repointed.

Mutation-verified three ways. Pointing the sync back at the acquiring wrapper
deadlocks a single UNCONTENDED sync — the evidence that the nesting defect is
real and that this split is what prevents it. Removing the wrapper's
acquisition turns the direct-write exclusion case red. Making the lock-free half

* test(hygiene): reach every tracked text file with the raw-byte guard

The guard claimed to protect tracked source from a raw NUL — the byte that
makes git classify a file binary and costs it its diff, its inline comments and
its three-way merge on GitHub. It matched on an end-anchored extension regex
covering the JavaScript family, so most of what this repo tracks was never
looked at: JSON, YAML, TOML, Markdown, snapshots, SQL, protobuf, the .NET
project files, the shell and batch scripts.

Worse, an extension regex cannot reach a file that has none. `Dockerfile`,
`CODEOWNERS`, `LICENSE`, the husky hook and every bare dotfile were unreachable
by construction — no amount of widening the pattern would have covered them —
so a second basename filter had to exist for the claim to be true.

It stays an allowlist rather than becoming "everything git tracks", because the
repo legitimately tracks binaries whose extensions must stay out.

The two filters together now collect every one of the 5000 tracked files except
31 — the 30 native prebuilds and one PNG — and those 31 are exactly the files
that carry a NUL. The allowlist no longer has a gap that is not a genuine
binary.

The planted-fixture cases route through the collector's own predicate rather
than straight into the scanner. The pre-existing fixture test bypassed the
filter entirely, so it could only ever prove the byte locator worked, never
that the collector would hand it the file — which is precisely how the gap
survived.

Mutation-verified both ways: removing the basename filter drops `.gitignore`
and `Dockerfile` from the planted results, and reverting the extension regex
drops `.json` and `.md`.

One added case is a preservation pin rather than proof — that tracked binary
formats stay out passes either way, and guards the allowlist from becoming a
denylist later.

* test(hygiene): stop the byte guard reading the vendored grammar tree

Widening the guard to every tracked text format also pulled in the vendored
tree-sitter grammars, and those are where the bytes are: four generated
`parser.c` files come to 62 MB between them, Kotlin's alone 33.7 MB. Excluding
that root drops 76 files but 66% of the bytes the scan reads — 97 MB down to
33 MB.

The exclusion is a single anchored prefix, matched case-sensitively with
`startsWith`, and both halves of that matter. A `vendor` path-SEGMENT match
would also drop first-party fixtures this repo tracks under directories named
`vendor` and `Vendor` — a Kotlin one, a PHP one, and three files under
gitnexus-web — silently narrowing coverage while the assertion pinned the loss
in place. Case-insensitivity would do the same to a `Vendor` directory at the
excluded root's own level.

The root is named in the guard itself, so the claim that it covers every
tracked text file stays honest about the one place it deliberately does not
look.

The cost comment was wrong and is now measured rather than estimated. It said
"the scan is ~10 ms" — ambiguous between locating the byte and reading the
files, and stale in its byte basis. Locating is ~14 ms; the reads dominate it
by two orders of magnitude, which is the actual reason for the concurrency pool
and the actual reason this exclusion is worth having. Every figure was
re-derived from the finished file rather than carried over from a draft.

The header's claim that `git ls-files` "never descends into vendor" was already
false — vendored code is tracked, so all 106 of its files were being reported
and read. Corrected here, where the distinction becomes load-bearing.

Registered in the cross-platform list first and given a shard weight second.
The weight table is only consulted for files already in that list, so a weight
entry alone is inert and the shard test filters unregistered keys without
complaining. The three-way split stays within 1.01x of ideal.

Mutation-verified three ways: a case-insensitive segment match, a
case-sensitive segment match, and a case-insensitive anchored prefix each turn
an assertion red.

The casing half was initially unfalsifiable — nothing tracked is named
`gitnexus/Vendor/`, so a tracked-set assertion could not distinguish it. Rather
than leave the claim unpinned or invent a fixture, it is pinned on the
predicate with a synthetic path; the tracked-set assertions pin the anchoring.

* test(group): make the strict-read test able to see which read ran

The file bound both registry exports to one mock:

    readRegistry:       (...args) => readRegistryMock(...args),
    readRegistryStrict: (...args) => readRegistryMock(...args),

so the case named for the strict read asserted a behavior it could not
attribute. Point the production call at the lenient export and every assertion
still holds, because the mock answers the same way whichever one is called.

That is not a hypothetical. With this file as it was, and `syncGroup` mutated to
call `readRegistry` instead of `readRegistryStrict`, all 32 tests passed — the
suite was blind to the exact substitution it exists to prevent, and the fix it
guards could have been reverted without a single red.

The exports now have separate mocks: the lenient one always resolves an empty
list, which is its real contract, and only the strict one is armed by the cases
that need a failure. The named case also asserts directly that the strict read
was called and the lenient one was not, so the attribution is explicit rather
than implied by an outcome.

No tests added — the unit is about what the existing ones can see.

Mutation-verified: the same substitution now turns 24 cases red, including the
named one, and everything stays green unmutated.

* test(group): pin the CLI output branches this PR introduced

The three sync outcomes and the status table's new labels had no assertions.
Every one of them is a sentence about what happened on disk, and this PR
corrected several that were false — a preserve branch that announced it had not
written the file it rewrites, a status table that called an unreadable registry
a missing entry. Text that describes state, with nothing pinning it, is how
those got wrong in the first place.

Six cases drive the real CLI end to end, through the two shapes that need no
indexed repo: members absent from the registry, and members registered at a
storage path with no index file, which makes every repo unreadable. The file
header claimed no LadybugDB-backed command was driven end to end; that is no
longer true and it now says so.

Each branch was suppressed in turn and its assertion goes red — all five that
the plan named.

One of those mutations first reported PASS, and the cause is worth recording: the
string being suppressed also appears inside a neighbouring branch's comment, so
the harness silenced the wrong line. That is a bad mutation, not a weak test.
The harness now asserts the marker it suppresses is unique before trusting the
result, and the redone check goes red.

The plan's sixth scenario is already covered by an existing case that asserts
both labels in one table, so it is not duplicated. A seventh case was added
beyond the plan: without a populated-list case, "prints neither line" would pass
just as well against a CLI that never printed that line at all.

Adds about 15s of measured spawn time locally; CI runs these against the built
dist, which is materially faster per spawn.

* test(group): assert the MCP payloads by exact shape, not by partial match

Nothing asserted what the group tools actually return. The sync response's
unreadable list and registry outcome, and the contract listing's incompleteness
fields, are documented in the tool descriptions an agent reads — and could have
been dropped in a refactor without a single test noticing.

The assertions are exact-shape rather than partial. A `toMatchObject` would let
a dropped key pass, which is precisely the regression these exist to catch: the
failure mode is an absent field, and a partial match is defined not to see one.
Absences are additionally asserted explicitly.

The tri-state has to survive the response boundary, and it is the reason exact
shape matters here more than usual. An absent `unreadableRepos` means the sync
never recorded what it could read, so the listing is a floor; an empty list
means it measured none; a populated list names them. Collapsing absent into
empty turns "we do not know" into "we checked, it is fine" — so a mutation that
replaces the conditional spread with `?? []` is covered specifically, not just
the outright deletion.

Mutation-verified per field: removing either sync forwarding line, deleting the
conditional spread, replacing it with the invent-empty form, dropping the
truncation triple, or hardcoding the provenance flag each turns an assertion
red.

* docs(group): stop the bridge input narrowing what unreadableRepos means

The same field had three definitions. The registry and the bridge metadata both
say it covers a repo this sync could not extract from — an index that would not
open, or an extractor that threw partway through, one bucket because the
consequence is one thing. The bridge input said only "whose index could not be
opened", which describes one cause and silently excludes the other.

It now points at the registry's definition instead of restating it a third
time. A definition written once and referenced cannot drift; three copies of it
already had.

* docs(group): record what the mtime pairing does and does not prove

The write-order fallback is a heuristic standing in for provenance, and a
future reader deciding whether to lean on it needs to know where it breaks
before they do. Both directions are now stated where the function is read
rather than only in the plan that introduced it.

The false-accept direction is a non-monotonic wall clock — mtime is realtime,
so an NTP step back, a snapshot restore, or container skew between the two
writes can leave a mis-paired set reading as ordered. Coarse filesystem
granularity is explicitly called out as NOT being that hazard, because it looks
like it: it collapses a pair written together to equal times, and equal is
accepted, which is the right answer for that pair.

The false-reject direction is any copy or restore that rewrites the database's
mtime after the metadata's. An intact legacy pair is demoted to a lower bound
and stays there until a sync re-stamps it, because nothing on the read path can
tell it apart from the swap window it imitates.

That second direction corrects a claim made while planning this work: that the
rule could only ever demote pairs already broken. It cannot. `cp -r` and
`rsync` without timestamp preservation both produce it on a healthy group, and
saying otherwise where the code is read would leave a future reader to discover
it the hard way.

* fix(storage): stop a corrupt registry quoting its own bytes into errors

`JSON.parse`'s SyntaxError embeds a window of the source around the failure —
V8 gives exactly ten characters either side — and the strict read rethrew it
untouched. The registry persists HTTPS remote URLs with their userinfo, so a
file that breaks next to one puts the credential into the error:

    Unexpected token 'L', ..."end.git"},LEAKCAN4RY"... is not valid JSON

The parse now has its own guarded region and reports the path and the failure
class, matching the two corrupt-registry errors already in this function.

The original error is discarded — not logged, not attached as `cause`. This
codebase's convention elsewhere is to hand the logger the Error so it captures
stack and cause, and following that convention here is precisely what would put
the byte window into the log. Under MCP stdio that log is written to the
client's log file on disk, so the thrown-error channel was never the only one
that mattered. The `catch` takes no binding, so the error cannot be reused by
accident later.

That was not theoretical: a sibling commit routes this message into
`unresolvableReason`, which `group status` returns to MCP clients and prints in
the CLI table. Every channel was traced — throw, cause, inspect with the full
chain, the logger, and both downstream consumers.

The leaking shape is narrower than it first appears, and worth recording. The
windowed message only fires when the parser fails at a value-start or trailing
position; a break inside a quoted string yields an unterminated-string error
carrying no window. So a plain mid-URL truncation does not leak — a short write
landing over a longer one does, leaving a URL fragment where a value was
expected. That is a reachable shape for the one machine-wide file every
gitnexus process writes.

The test asserts the message still names the path and the corruption class, not
only that the secret is absent. Asserting absence alone would stay green if the
message became empty.

Mutation-verified: restoring the raw rethrow brings the token back verbatim.

* docs(storage): drop the stale lenient call-site count

The docstring said keeping `readRegistry`'s signature untouched leaves "its
nine other call sites" unaffected. There were thirteen when the discrepancy was
noticed and fourteen by the time it was fixed. The same figure appeared in the
test file's header.

Replaced rather than corrected. A count in prose next to code that moves is a
claim that goes stale without anything failing — which is the defect class this
change set exists to remove, so re-seeding a fresh number would be repeating it
with a longer fuse. The argument was never about the quantity: leaving the
signature alone keeps every lenient caller provably unaffected whether there is
one or fifty.

Also withdrawn while here: the claim that the bridge schema-version guards
diverge between call sites. They do not — the two forms are complements for
every value a writer can produce, there are three sites rather than the two
claimed, and all three agree. Recording a divergence that does not exist would
leave a future reader chasing it.

* docs(group): add an auditable finding-to-commit map

The Definition of Done claims every review finding has exactly one commit and
that reverting it reintroduces that finding and no other. Without a map that
claim is only checkable by whoever holds the review report, which is one person
for a short time.

The map lists all 28 primary findings against their commits, the three findings
whose suggested fix was deliberately not implemented and what shipped instead,
and the four defects found while executing that no reviewer raised.

It also records the revert contract honestly. Revertability is
dependency-aware, not absolute: the shared completeness helper has three
consumers, so reverting it alone does not build. That coupled set is named
rather than left for someone to discover mid-revert.

Two sections exist because the work produced them, not because the plan asked.
Six claims in the plan turned out to be contradicted by the code — among them a
scope predicate that would have reintroduced the bug its unit was closing, and
an assertion about the mtime rule that was simply wrong. Recording only the
findings would leave the impression the plan was followed as written. Five
residual risks are listed for the same reason, including that R14 is not met on
this PR: the diff attribute works locally but GitHub reads it from the base
side, so this PR's own sync.ts stays binary in the web view and every PR after
it renders as text.

Not under docs/ — that path is gitignored, so a map written there would never
reach the PR and the audit it exists for could not be performed by anyone else.

* fix(group): read a version that is not a version as no provenance

Raised by the check bot on this PR, and real — the bot found one symptom of it;
the field splits four gates apart, not one.

`readBridgeMeta` accepted any numeric `version`, and `0` is this file's word for
"no provenance". A parseable but impossible value — negative, fractional — is
not a schema version, and each gate that reads the field disagreed about it:

  ensureBridgeReady      `> 0 && !== CURRENT`  → opens the bridge
  openBridgeDbReadOnly   `> 0 && !== CURRENT`  → opens the bridge
  bridgeExists           `=== 0 || === CURRENT` → says it is not there
  bridgeProvenanceUnknown `=== 0`               → reports the answer complete

Four verdicts about one file, and the last one is a fail-open of exactly the
class this PR exists to close: a bridge nothing can vouch for, reported as
fully accounted for.

The suggested fix was to widen the provenance check to `<= 0`. That closes the
reported symptom and leaves `bridgeExists` still disagreeing with both openers,
so it is fixed at the reader instead: a version that is not a positive integer
normalizes to the sentinel the gates were all written against. One change, four
gates agreeing by construction, rather than teaching each of them the same new
case and hoping the fifth reader remembers.

Infinity is covered too, though by the pre-existing type check rather than the
range one — JSON cannot carry it, so it arrives as `null`. Recorded at the test
so the case is not mistaken for proof of the range check.

Mutation-verified: restoring the loose numeric check turns the negative and
fractional cases red.

* fix(group): stop a malformed contracts.json reading as an unresolvable registry entry

Raised by the check bot on this PR. Its stated mechanism was wrong — `loadMeta`
returns null on every error and `checkStaleness` catches everything, so neither
can throw — but its conclusion was right, and there is a concrete path it did
not name.

`readContractRegistry` is a bare `JSON.parse(content) as ContractRegistry` with
no shape check, and the snapshot lookup guarded only the registry object:

    registry?.repoSnapshots[repoPath]

The `?.` covers `registry` being null, not `repoSnapshots` being absent. A
contracts.json without that field — a legacy file, a hand-edit, a truncated
write — throws `TypeError: Cannot read properties of undefined`, which lands in
the catch that labels failures as unresolvable GLOBAL-registry entries. So a
group whose own contracts file is malformed reported every repo as a broken
registry row, sending the operator to repair a file that was fine.

An error from one cause presented as another, which is the defect this PR has
been removing everywhere else.

The optional chain closes the crash. The try is also narrowed to the call that
earns the label: only `resolveRepo` sits inside it now, so "did not resolve"
describes something that actually failed to resolve rather than whatever else
happened to throw nearby. The comment records why the other two calls in that
block cannot throw, so the next reader does not have to re-derive it.

* refactor(group): give the completeness fold a module no native binding reaches

The shared fold ended up in `cross-impact.ts`, which statically imports
`bridge-db.ts` and through it the native LadybugDB binding. `groupContracts`
therefore reached it through `await import('./cross-impact.js')` — loading that
whole module graph to run a Set union and a ternary. Measured: 44-51ms and
8.4MB of RSS on first call, paid once per MCP server and once per
`gitnexus group contracts` invocation.

`completeness.ts` holds the vocabulary and the fold and imports nothing but
types. `service.ts` imports it statically; the lazy import and the comment
justifying it both go. `cross-impact.ts` re-exports so the three surfaces still
have one import site for the vocabulary.

Three other duplications collapse into the same move.

`traceCompleteness` was hand-writing `{truncated, truncationReason,
riskEpistemic}` — a third writer of the pair `truncationFields` exists to keep
mechanically linked (#2787), in the file the consolidation had just touched. It
calls the helper now.

`recordedRepoList` existed twice, byte-identical, one copy's docblock saying it
mirrored the other. That gate is the predicate the whole
absent-vs-empty-vs-populated distinction rests on, applied to the same two
lists on both the registry and the bridge — tightening one copy would have
fixed one surface silently. One definition now.

The trace's scope predicate compared repo paths with `===` while its sibling in
`cross-impact.ts`, added in the same change, went through `repoInSubgroup` with
a comment about not growing a second notion of membership. It had grown one:
the helper normalizes separators and strips trailing slashes, so the same
group.yaml spelling could be in scope for impact and out of scope for trace.

Also here: `registryIdentifies` was a third, weaker copy of the registry's path
rule — it skipped `realpath`, so a symlinked row would not match where the real
resolver would. It uses `canonicalizePath`/`registryPathEquals` now.
`contracts.json` is no longer respelled as a literal in `sync.ts`; `storage.ts`
owns the name it reads and writes. And the runtime-truncation predicate is
bound once instead of written out at both the flag and the reason, where
forgetting the second would label a retry-able answer `incomplete-sync`.

* fix(group): give the lost-the-race sync its own outcome instead of overloading preserved

A sync that finds contracts.json replaced while it waited for the lock reported
`registryOutcome: 'preserved'`. That value already meant something else, and the
two differ in exactly the thing the value is for: `preserved` rewrites the file
with this run's diagnostics; this path does not touch it and deliberately does
not record them.

So both surfaces stated something false about disk. The tool description told
agents `preserved` means "contracts.json was rewritten ... refreshing only
missingRepos/unreadableRepos to describe THIS run (the file changed)". The CLI
said "only the unreadable/missing repo lists were refreshed to describe THIS
run". On the lost-race branch nothing was written and the log line beside it
says so outright.

That is the defect class this whole change set removes, reintroduced by the
change set itself — and the reasoning recorded at the time makes it worse, not
better: a new value was rejected because it "would fall through cli/group.ts's
outcome chain, which has no fallback branch". A renderer limitation decided a
domain value, and the description then had to cover two states with one
sentence that fits one of them.

`superseded` is its own outcome now, described in its own words to agents and
rendered in its own words at the CLI. The registry on disk is FRESHER than this
response's diagnostics, which is the opposite of every other non-written
outcome and is why an agent needs to tell them apart.

The CLI renders from a `Record` keyed on the union, so the next outcome fails
the build here rather than printing nothing — the gap that made folding the
state in look like the cheap option.

The description guard is scoped per clause rather than over the whole string.
It forbade "untouched" anywhere, which was right when one clause could only lie
in that direction and wrong now that another clause is accurately untouched. It
also asserts the superseded clause says so, or the two collapse back into one
word for two states.

Found by the quality pass over this branch, not by review.

* test(group): read bytes and stat through one handle, not two path lookups

CodeQL flagged both sites as `js/file-system-race`, high severity, and it is
right about the shape. `stat(path)` followed by `readFile(path)` is two
independent path resolutions with a window between them — the classic
check-then-use race.

It also made the assertions weaker than they read. These two tests exist to
prove a specific file was left untouched, and two lookups can land on different
inodes, so "the bytes and the mtime are both unchanged" was not actually a
statement about one file. The distinction is the whole point here rather than a
technicality.

`snapshotFile` opens the path once and takes both answers from that handle. The
race is gone because there is no second lookup, and the assertion now genuinely
concerns one inode.

I had previously triaged these as below the ruleset's threshold and left them
for the repository owner. That was wrong: they carry
`security_severity_level: high`, and the branch ruleset gates on
`high_or_higher`, so they were blocking the merge rather than sitting under it.

* fix(group): resolve HTTP consumers through configured clients and constant route tables

Cross-repo linking found almost no frontend consumers because the Node/TS
consumer pattern required two things application code never has: a receiver
literally spelled `axios`, and an HTTP path that is a string literal at the
call site. Real apps call a configured instance and pass the path by reference
from a shared route table, so both halves of every call live in other files.

Widen the pattern to any identifier receiver with an HTTP-verb method, then
admit the match only after PROVING the receiver is an axios instance —
following local aliases, default/named imports and `export *` barrels back to
an `axios.create(...)`, including when that call is an argument to a factory
that decorates and returns the instance. The proof gate is load-bearing:
EXPRESS_SPEC matches `router.get('/x', handler)` as a provider, so admitting a
receiver on spelling alone would re-emit every Express route as a consumer of
itself.

Resolve the path argument through the existing language-agnostic constant fold
(`constant-resolver.ts`, #2391) via a new JS/TS binding, mirroring how
`python-const-resolver.ts` binds the same core. The binding adds the two
JS-shaped facts Python has no analogue for: object-literal route tables
flattened to dotted literal keys (`API_ROUTE_PATH.LINKS`), and export aliasing
(`export default`, `export { a as b }`, `export *`). Templates and `+` concats
fold partially, so a mixed path keeps its known prefix instead of collapsing to
`{param}/{param}/...`.

Cross-file facts come from a `prepareRepo` pre-pass, the hook FastAPI prefix
resolution already uses. The three JS/TS plugins share one pass via a WeakMap
keyed on the orchestrator's memoized file list.

Every resolution floors to `null` (skip) rather than a guess: an ambiguous
import specifier, an unprovable receiver, or a fold that overruns its depth
leaves the call site exactly as unmatched as before. An unresolved path is a
missing contract; a wrong one is a false cross-repo link.

Measured on a real Next.js frontend (874 source files): consumer contracts
7 -> 160, none lost.

* fix(group): tighten the JS/TS HTTP consumer proof gates and bound the fold

Addresses the review findings on #3008. Widening the axios consumer query
moved precision out of the tree-sitter pattern and into runtime gates; most
of these are one of those gates leaking.

Keying
- scanBundle normalizes fileRel ONCE and uses that key for both the receiver
  gate and the path fold. isHttpClientRef read the raw value while the fact
  map is written under normalizeRel(rel), so any non POSIX path returned zero
  consumers and a key miss is indistinguishable from "not a client".

Proof
- containsAxiosCreate (subtree containment) becomes bindsAxiosClient: the
  instance must be the bound VALUE, or reachable inside the arguments of a
  wrapping call whose result is bound. An object literal, ternary, array or
  new X(...) binding no longer makes a cache or registry an HTTP consumer.
- A folded first argument must look like a path: no whitespace, not wholly
  numeric, and not starting with an unresolved term. The check runs on the
  ${...} to {param} normalized shape, so a placeholder whose source contains
  spaces does not drop an otherwise anchored path.
- A template or concat whose LEADING term never resolved returns null, which
  is what the docstring always claimed.
- The literal receiver axios with a literal or template argument keeps its
  pre-PR output verbatim, so the widening only adds detections.

Resolution
- resolveJsImport checks ambiguity across ALL candidate extensions, not within
  one, so a .ts/.tsx or .ts/index.ts collision skips instead of picking a
  winner. Two spellings of one module still resolve by precedence.
- A single segment bare specifier with no alias sigil never binds to a repo
  file, so a Node builtin or npm package cannot be "proven" an axios client.
- resolveExportedMember walks every export * edge and returns null when two
  barrels answer differently.
- Imports are collected in a hoisting pre-pass, so a client bound above its
  own import statement is still proven.

Termination and cost
- MAX_EXPR_DEPTH and MAX_CONCAT_TERMS bound the path fold, flattenConcat walks
  the left spine iteratively, and buildImportMap is explicit stack. A file
  nesting template substitutions 4000 deep threw RangeError out of scan, which
  sync.ts records as an unexplained missing repo with every contract dropped.
- MAX_FOLD_LENGTH applies to accumulated output, not per term, and to the raw
  literal fallback. The per term cap was a 2048x amplifier and the result is
  persisted into contractId.
- resolveJsImport is backed by a basename index and memoized per repo, and
  resolveConstant accepts the key set instead of rebuilding it per fold.
  2000 file repo with one bare npm import: 11074 ms to 1250 ms.
- prepareRepo measures its ceiling in bytes, parses inside the try, and skips
  the parse pass entirely when the string axios appears in no candidate file.
  It carries only file identities between its two passes, never their text.

* fix(group): let a path-shaped all-numeric consumer path through the gate

The shape gate rejected any wholly numeric path, which also dropped
`client.get('/123')`. The leading slash is the evidence that separates a
route from a constant that merely folded to digits: a bare "5000" out of
`CONFIG.TIMEOUT` still matches every one-segment provider route and is still
refused, while a path written as a path is kept and normalized to {param}
the same way it always was.

* fix(group): decide the axios receiver on evidence, not only on its spelling

The bare name `axios` was trusted with no proof, which is right for the
convention and wrong for a file that binds that name itself:
`const axios = fakeFactory; const api = axios.create(); api.get('/x')` was
admitted as an HTTP consumer, and so was a test file whose `axios` is a mock
object with a `create` method.

extractJsModuleFacts now records whether the file declares its own top-level
`axios` binding, and the spelling is trusted only when it does not. The other
half of the same fact is that CommonJS was invisible: `const ax =
require('axios')` resolved to nothing at all, and the un-aliased form worked
only because `axios` happened to be the name the spelling shortcut trusted.
Requires are collected alongside imports now, so a receiver is admitted when
it IS the axios module (the bare spelling, or a declared import or require of
'axios' under any name) or when it traces to an `axios.create(...)` instance.

Verified across the receiver matrix: shadowed local, shadowed mock object,
CJS require aliased and not, ESM import aliased and not, express router and a
plain Map all land where they should.
