d2f768245e fix(routes): address round-2 review — provider hooks, FQN fold, interface nesting
F1 (High): production harvest silently dropped routes when the constants
class is not named *Constants (e.g. ApiPaths). The content gate is now
SYNTAX-driven (static-final String field or any class import) and lives in
the provider (moduleConstantHeuristic), not a shared-layer regex.

F2: shared ingestion layers no longer branch on language. The harvest and
the qualified-ref fold run through new provider hooks
(extractModuleConstants / foldRoutePathOperands); parse-impl resolves the
provider by filePath (getProviderForFile). Python wires the same hooks for
architecture parity.

F3: multi-segment FQN chains (com.example.ApiPaths.USERS) now flatten
recursively; verified via tree-sitter that the existing query already
captures the whole nested field_access — the gap was resolver-side only.

F4: implicit-final interface semantics no longer leak into nested classes
at type boundaries (JLS 9.5).

F5: nested same-name shadowing now drops the stale entry (rebind-drop,
matching Python #2391 semantics) instead of keeping the first binding.

Tests: 9 new unit tests (27/27) + real-pipeline e2e over a reviewer-shaped
fixture (non-*Constants class, cold run + warm parse-cache replay) — the
exact production gap unit tests missed.

fad5f88002 fix(resolver): bound qualified-ref recursion depth for self/mutual import cycles
Maintainer review point: the qualified branch of resolveJavaConstant
recurses through resolveJavaImport without a guard — a self-import
(X = SelfConsts.X + ...) or a pair of mutually-importing constants
would recurse without bound before reaching the shared fold's
visited-stack, which only guards the bare-name path.

Bound the Java-qualified walk with a depth cap (32) and thread it
through every recursive call. Two regression tests use real repo
shapes (repoOf fixtures): self-import and mutual-import cycles both
terminate with null (skip floor), as before, but promptly.

Also drops the stray machine-local .gitignore entry that rode along
from the fork's dev branch.

330514f13e fix(feign): guard @RequestLine against the constant-valued shape
A constant-valued `@RequestLine(SOME_CONST)` is captured as @value_expr,
not @value, so `valueNode` is undefined in that shape and the literal
dereference crashed the scan. Skip instead — folding verb+path literals
through the constant map is out of scope for this PR.

Found in maintainer review of #2980.

284d587ea8 docs(cache): note Java constant-route capture set in the SCHEMA_BUMP ledger
The Java constant-route harvest (route-extractors/java-const-resolver.ts +
the spring.ts operand branch + the parse-worker Java constant harvest)
changes the worker capture set: a warm pre-feature cache replays
moduleConstants=0 captures verbatim and silently drops every constant-based
Spring route on unchanged files. After rebasing onto current main the
ledger already sits at 70, whose capture set post-dates and includes this
harvest, so v70 invalidates those caches — no additional bump is needed.

a4fc7a05f8 fix(review): address bot review findings on PR #2980
- P2-1 (real): spring.ts route loop dropped every @value_expr match — the
  '!valueNode' guard ran before the operand branch, so ingestion emitted zero
  constant-referencing routes. Guard now accepts @value_expr when @value is
  absent; two downstream valueNode dereferences made conditional.
  Added 2 extractor-level regression tests (16 total).
- P2-2 (real): collectSpringTypes copied rawPath:'' for constant routes into
  the shared Spring inheritance view — now skipped there (fold happens in
  scan(); empty-path noise would leak into inheritance-based providers).
- P1-1 (false positive): Java 'static final' allows exactly one initializer
  (duplicate declarations are compile errors), so the Python-style rebinding
  shadowing cleanup does not apply — documented at the site.
- P1-2 (false positive): constant-resolver.ts and prepareDurableParsedFileChunk
  both exist on upstream main (#2391 / parsedfile-store.ts:562); the bot's
  'repository lookup' appears to have compared against a stale index.
- P3: removed dead FQN_CONTROLLER fixture.

Real-repo regression: 589 cross-links / 2423 contracts (was 2424 — the
dropped contract is the empty-path inheritance artifact fixed above).

41d874dcb3 feat(group): resolve Java constant-based route paths via repo constant map
- prepareRepo builds repo-wide Java constant map (constant-definition files only,
  cheap regex gate; per-file try/catch so one bad file degrades not forfeits)
- bind parser language in prepareRepo (orchestrator hands over a bare Parser)
- scan() lazily overlays the importing file's own import table (extracted from
  the tree already in hand, zero extra parses) before folding operands
- foldJavaOperands resolves qualified refs (Class.CONST) + static imports +
  string concatenation against the merged view; unresolved refs are skipped,
  never guessed

Real-repo validation (winning-winex-opt, 23k Java files):
  providers 2 -> 1701 (1700 source_scan_resolved), cross-links 0 -> 589 exact
Unit: 14/14 (java-route-const-resolver.test.ts)

* fix(typescript): resolve imports against declared config, not path suffixes (#2953)

TypeScript/JavaScript/Vue import resolution ended in `suffixResolve`, which
answers "does any file in this repo have a path ending in this specifier?" and
answers it by dropping leading segments until something matches. That is not
module resolution, and it failed in both directions at once:

  - `@acme/telemetry/nest`, a registry dependency with no in-repo file, landed
    on the repo's only path ending in `nest/index.ts` — a false IMPORTS edge at
    confidence 1.0, indistinguishable downstream from a real one. The reporter
    measured 44 of 74 `apps/ -> packages/` edges landing on two such files.
  - `@repo/utils`, a first-party workspace package, resolved to nothing: its
    name lives in `packages/utils/package.json` and appears in no file path, so
    a path matcher cannot find it. Zero CALLS from 75 import statements.

Both come from the same missing input — nothing read the config that says what
exists — so both are fixed by reading it.

Replaces the suffix matcher on this path with the algorithm tsc and Node
actually run, in their order: relative/absolute, `#imports`, tsconfig `paths`
(longest literal prefix wins, every target tried), tsconfig `baseUrl`, then the
workspace package's own `exports`/`main`. A specifier none of those declare is
external, and resolves to nothing. There is deliberately no fallback.

New:
  - `typescript/tsconfig.ts` — every tsconfig/jsconfig in the repo with
    `extends` chains resolved, nearest-config-wins per file. The old loader read
    three filenames at the repo root, required `paths` to exist, and kept only
    `targets[0]` — none of which describes a monorepo, where `apps/web/
    tsconfig.json` is what governs `apps/web/src/main.ts`.
  - `typescript/module-resolution.ts` — the algorithm.
  - `typescript/file-candidates.ts` — 11 TS-family extensions, replacing a
    shared 39-entry list spanning every indexed language, so a TypeScript
    import can no longer resolve to a `.py` file.
  - `import-resolvers/node-workspace-packages.ts` — in-repo manifests, with
    `exports` subpath maps, patterns, condition nesting, and the restriction
    that a package declaring `exports` exposes only what it lists.

The per-pass `SuffixIndex` is gone from these three adapters: real resolution
derives nothing from the file list — every candidate comes from a declared
source and is checked with one `Set.has` — so there is nothing left to cache.
Their `*-import-index-reuse` guards and the JS index-vs-scan differential are
deleted with the mechanism they measured; the cross-language contract test
moves the three languages to its existing `KNOWN_UNINDEXED` channel, and pins
the exemption as a list so a fourth arrival is deliberate.

Python, Ruby, Java, Go and the rest still route through `suffixResolve` and are
untouched here.

* test(scope-resolution): assert every resolver refuses external imports (#2953)

One property, for all 16 registered resolvers: a specifier naming something
outside the repository must not resolve to a file inside it.

That is the property #2953 was filed against, and its violation is not a
missing edge but a fabricated one — an IMPORTS edge at full confidence between
two files with no relationship, which `impact` then reports as blast radius.
The mechanism is shared (`suffixResolve`), so the guard is too.

Every case pairs an external specifier with a DECOY: an unrelated in-repo file
whose path ends the way the specifier does. Without one a resolver that merely
found nothing would pass while holding no property at all, so each case also
asserts the decoy is reachable by the spelling that SHOULD find it — a typo in
a fixture cannot manufacture a pass.

Two fixtures had to be corrected before the results meant anything, and both
would have recorded a false gap:

  - C# reads its #1881 gate from scanned namespace evidence and fails OPEN
    without any, so passing `undefined` measured nothing. Armed, C# holds.
  - C++ was posting a pass on an extension mismatch (`vector` could never match
    `src/vector.hpp` whatever the resolver did). Given the header spelling, it
    does not hold.

Result: six hold it — TypeScript, JavaScript and Vue because they resolve
against declared config only (#2953); Python (#898) and C# (#1881) because they
gate the fallback on in-repo evidence; Rust because `::` never decomposes into
a path suffix, which the decoy-reachability arm confirms is a real pass rather
than a vacuous one.

Ten do not, and are recorded in KNOWN_GAPS with what each currently answers:
Java, Kotlin, Go, Ruby, PHP, Dart, Swift, C, C++, COBOL. The map is a work
list, not an allowance — the entries are ASSERTED, so a language that starts
holding the property fails here and its line gets deleted deliberately rather
than rotting into a lie.

* fix(typescript): admit only declared workspace packages, and fix four resolver defects (#2953)

Review of #2956 found one boundary bug and four correctness defects. The
boundary one is the same defect class this PR exists to fix, arriving from a
different direction.

## The workspace boundary (review)

`loadNodeWorkspacePackages` registered every `package.json` the repo-wide scan
found, and never read `pnpm-workspace.yaml` or a root `workspaces`
declaration. Finding a manifest is not the same as the workspace admitting one:
an app importing registry package `foo` would bind to an excluded fixture or
example that happens to declare `name: "foo"` — the false-positive half of
#2953, from a new source of evidence. This repository is the example, since
`test/fixtures/**` declares `@repo/utils` among others.

The admitted set now comes from the declaration — `workspaces` (array and yarn
object form), `pnpm-workspace.yaml`, `lerna.json`, with `!` exclusions and
`*`/`**` — plus the root package itself. A repo that declares no workspace has
exactly one package: the root. A negative fixture pins it, with a named package
outside the declared globs that must not resolve.

## Four defects

  - tsconfig `paths` targets were resolved against the config's own directory
    when it declared `paths` but inherited `baseUrl`. tsc resolves them against
    the EFFECTIVE base, so an extending config loaded the right alias pattern
    and pointed every target at the wrong directory.
  - two configs in one directory were ranked by directory-listing order, so
    `tsconfig.base.json` could govern instead of `tsconfig.json` and a config's
    own `paths` went invisible. Found by the test written for the fix above.
  - an unexported package subpath also tried `<dir>/src/<subpath>`. Nothing
    declares that mapping; it is the same kind of guess this PR removes, and
    the import it "resolved" is broken in the real project too.
  - `imports` pattern keys (`"#internal/*"`) were looked up exactly, so a valid
    `#internal/foo` never matched. `exports` and `imports` now share one
    matcher, which is where they should never have diverged.
  - a relative specifier climbing past the repo root was silently clamped, so
    `../../../secret` from `src/main.ts` became `secret` and could resolve a
    root file it never named.

## Test rigor

The conformance suite asserted less than it claimed. The decoy-reachability arm
only checked non-empty, so five cases paired `reachesDecoy` with a different
file than `decoy` and passed while establishing nothing; the KNOWN_GAPS arm
likewise accepted any in-repo answer instead of the recorded one. Both now
assert the exact file. The reachability arm runs only for languages that HOLD
the property — for a gap language the recorded-answer assertion IS that proof,
and for Swift and COBOL no other spelling exists, since `Foundation` and
`EXTERNAL` name the in-repo directory and copybook as well as the external
module, which is precisely why those resolvers cannot tell them apart.

## Benchmarks

Both `--check` guards were red, and both were reporting something true.

`import-target`: the ts-family arms resolved 0 of 3200 imports. Their corpus is
bare specifiers with no config, which the deleted `suffixResolve` answered
without one — so the arms measured an empty branch while printing a clean
scaling ratio. Each now carries the config its corpus is spelled for, and the
`deep` arm's uniform prefix reaches it. THE FINGERPRINTS THEN MATCHED THE
RECORDED BASELINES EXACTLY: same corpus, same targets, once the config it
always implied is passed explicitly. Retained per-pass index went from
26 745 296 B (js, ts) and 28 884 016 B (vue) at 32 000 files to 0-16 B, because
these resolvers no longer build one; they move to the `HEAP_BOUNDED` tier rust
already occupies for the same reason. Depth ratio moved 2.0 -> ~2.2 and the
budget goes to 2.6: candidates now carry the 16-segment baseUrl prefix, so each
`Set.has` hashes a longer string — linear in path LENGTH, independent of file
COUNT.

`scope-capture`: TypeScript capture fingerprint drift, caused by this PR's 12
new `.ts` fixtures entering the corpus. Attribution is exact rather than
inferred — moving that one fixture directory aside returns the fingerprint to
`f719163e…` byte-for-byte with `fixture_count` back at 155 and all 15 languages
passing.

* fix(typescript): honour exports fallback arrays, paths precedence and package extends (#2953)

Second review round. Four findings, judged against what this tool is: a static
analyser building a code graph, not a compiler. The bar is resolving what the
project DECLARES, on a checkout that may never have been built or installed,
and never inventing an edge.

  - `exports` and `imports` ARRAYS were skipped. An array is Node's ordered
    fallback list, and `{"./feature": ["./dist/feature.js", "./src/feature.ts"]}`
    is exactly what a workspace package publishes to mean "built output, or
    source". Skipping it dropped the declaration entirely and left the package
    looking as though it exported no subpaths. The source arm is the one that
    matters here, because `dist/` is build output and is not indexed — and for
    a static analyser the build need not have run at all.
  - an exact `paths` pattern did not reliably outrank a wildcard. `a` and `a*`
    both match `a` with the same literal prefix length, so sorting on length
    alone left tsc's exact-wins rule to declaration order.
  - package-form `extends` (`"@acme/tsconfig"`) was refused outright. Not
    indexing `node_modules` is different from not READING it, and a shared
    internal base is where a monorepo puts the `paths` its packages import
    through. It is now read from disk, walking `node_modules` up from the
    extending config the way Node does, and absent on an un-installed checkout
    it degrades to whatever that config declared itself.

    The test pins what tsc actually does with such a base rather than what one
    might hope: `extends` never rebases `baseUrl`, so a package base's paths
    point at the package's own directory. That is why a published base rarely
    contributes aliases a repo's files resolve through, and why the
    `@tsconfig/*` family — which sets `target` and `lib`, never `paths` — is a
    no-op here either way.
  - CodeQL flagged `String.replace('*', …)` in two places as replacing only the
    first occurrence. Node subpath patterns and tsconfig `paths` both allow AT
    MOST one `*`, so that IS the specified behaviour — but the spelling states
    it by accident and reads as the replace-all footgun. `substituteStar`
    slices at the known index and says the rule.

* fix(typescript): treat `exports` as the whole interface, and keep empty tsconfig scopes (#2953)

Third review round. Two findings, both valid, both cases of this resolver being
laxer than the thing it models — which is the direction that fabricates edges.

  - `exports`, when a manifest declares it, is the package's ENTIRE public
    interface: Node ignores `main` outright and refuses any subpath the map
    does not list. This resolver already honoured that restriction for
    SUBPATHS and not for the package ROOT, which is the same rule. A manifest
    exporting only `"./feature"` therefore still answered a bare `@repo/pkg`
    with `main` or `src/index` — an edge for an import that does not resolve in
    the real project. Legacy and conventional root candidates are now offered
    only when there is no `exports` field at all.

  - a tsconfig declaring neither `baseUrl` nor `paths` was dropped rather than
    kept as an empty scope, so `tsconfigFor` fell through to an enclosing
    config. A package whose own tsconfig declares no `baseUrl` — meaning its
    non-relative specifiers are package lookups — silently inherited the repo
    root's aliases instead. An empty scope is the accurate answer for such a
    file, and only a scope can express it.

Both are pinned at the level they broke: the manifest arms assert what
`readManifest` produces, not a hand-built package, since the resolver honouring
empty entries and the loader producing them are different claims.

* fix(scope-resolution): make interface dispatch generic-instantiation aware (#2912)

Interface-dispatch fan-out walked the subtype closure with generic arguments
erased, so `IValidator<string>` and `IValidator<int>` — one declaration, one
subtype list — were indistinguishable and a call through the first reached
`IntValidator.Check(int)`, a target no runtime dispatch can produce.

The arguments were already in the capture, unread: every language anchors
`@reference.inherits` on the whole base node while `@reference.name` keeps the
erased base. `ReferenceSite.typeArguments` is therefore derived generically in
`scope-extractor.ts` from the anchor's own spelling — no per-language query
changed — covering C#, Java, TypeScript, Kotlin, Go (`Base[int]` embedding),
Python (`Base[User]`) and Swift; Rust and Dart anchor on the bare name and get
nothing, which reads as "unknown". `preEmitInheritanceEdges` is the only code
that pairs a heritage site with a resolved (subtype, supertype), so it records
the instantiation there and hands it to the dispatch pass.

The closure is then walked carrying a substitution, as a type checker would:
`Wrapper<T> : IValidator<T>` binds T to the receiver's argument and stays
reachable from every instantiation, while its own subtypes are matched against
that binding. An incompatible hop is skipped without being marked seen, so a
type reachable by a second, compatible path still gets its edge, and without
descending, since its subtypes inherit the mismatch.

Pruning happens only on positive evidence that two instantiations differ.
Unknown arguments on either side, an arity that does not line up, an unresolved
qualified spelling of the same simple name, or an argument that might be a type
variable the language never captured all keep the target. Telling an uncaptured
type VARIABLE from a concrete type is the crux: `typeParameters` is absent both
for a non-generic declaration and for every declaration in a language whose
query omits `@declaration.type-parameters`, so the pass reads the evidence in
front of it — one run resolves one language, so a single generic declaration
anywhere in it proves the captures record parameters. A language recording
neither arguments nor parameters keeps exactly its pre-#2912 fan-out.

Type arguments are compared as resolved declarations rather than spellings, so
`Models.User` and an imported `User` are one type; the new optional
`ScopeResolver.normalizeTypeArgument` hook canonicalizes a language's predefined
aliases, implemented for C# (`string` ≡ `String`) where mixing the spellings
would otherwise delete a real implementor.

Fan-out cap, skipped-target reporting, overload selection and non-generic
closure behaviour are unchanged. SCHEMA_BUMP 60 -> 64: the heritage arguments
are a parse-time capture, so a warm cache would replay pre-fix sites and leave
the filter silently inert on unchanged files (61/62/63 are claimed by open PRs).

* fix(scope-resolution): close the two generic-dispatch gaps (#2912)

The first commit left two shapes on the pre-#2912 fan-out. Both are now
covered, and the second one turned out to need a route the pipeline did not
have at all.

**Folded receivers (Cases 0 and 3b).** `this._validator.Check(x)` is typed by
the compound fold, and the fold answers with a CLASS — which is exactly what
loses the instantiation, since `IValidator<string>` and `IValidator<int>` fold
to one declaration. The fold now reports the SPELLING it typed each receiver
position from, through a pure side channel (`recordReceiverType`) added to the
one helper every declared-type route already shares plus the two return-type
routes; resolution is unchanged whether or not a caller passes it. The reader
keeps the last report and uses it only when it names the class the fold
returned, so an intermediate position cannot lend its arguments to another
class. This covers the dependency-injection shape the issue is really about —
a field-held generic interface — and multi-hop chains, where it is the last
hop's spelling that types the receiver.

**Rust and Dart heritage.** Neither recorded arguments, for two different
reasons, so both routes exist now:

  - Rust's `@reference.inherits` anchor is the trait identifier INSIDE a
    `generic_type`. Widening the anchor would move the site's range, and that
    range is part of every inheritance edge's id, so the arguments arrive
    through a new `@reference.type-arguments` sub-tag instead.
  - Dart's `implements` / `with` never become reference sites at all: they
    travel as heritage MARKERS and their edges are emitted by the language
    hook. The arguments ride the marker payload as an optional fourth field
    (dropped, not encoded, when the spelling contains the marker delimiter),
    and `ScopeResolver.emitHeritageEdges` now receives the same sink
    `preEmitInheritanceEdges` writes to, so whichever pass emits an edge
    records that edge's instantiation. Dart also gained the
    `@declaration.type-parameters` capture, without which its own type
    VARIABLES are indistinguishable from concrete arguments and
    `class Box<T> implements Validator<T>` would be pruned from every
    instantiation.

Note this makes Rust and Dart record their instantiations; it does not make
them fan out. Interface dispatch still fires only for a receiver whose folded
type is an `Interface` symbol, so a Rust `Trait` or a Dart abstract `Class`
receiver has no secondary targets to filter. Widening that gate emits new
edges for several languages and belongs to its own issue.

**Two matcher rules the wider coverage exposed.** A WILDCARD names a set of
types rather than one — `Repo<? extends User>` holds a `Repo<User>`, and
Kotlin's `Repo<*>` / `Repo<out User>` say the same — so a position with one on
either side is unknown; nullable spellings trip the same test, which costs a
little precision in the safe direction. And insignificant whitespace inside a
nested spelling (`Map<string, User>` vs `Map<string,User>`) is no longer a
difference.

One expectation changed in the #2833 field-receiver matrix: a
`Repo<Repo<User>>` receiver no longer reaches `UserRepo implements Repo<User>`.
That edge is precisely the false positive this issue is about, and the primary
edge to the interface's own declaration — which is what the matrix row exists
to prove — is untouched.

* refactor(scope-resolution): apply the quality pass to the #2912 change

Three cleanups, no behaviour change.

**One balanced-list scanner, not two.** `erasedTypeApplication` and
`typeApplicationArguments` each carried a copy of the same fiddly scan — one
bracket list, balanced, closing on the last character, non-empty — differing
only in what they did with the result. Both now call `balancedTailList`; the
rule that rejects `User[][]` and `Repo<User>?` lives in one place instead of
being free to drift between two.

**The receiver's arguments are parsed after the gates, not before them.**
`emitInterfaceDispatchFor` takes the receiver's declared SPELLING and parses it
itself, once the owner is known to be an Interface with subtypes. Every one of
the five cases calls it unconditionally and the overwhelming majority of
receivers are concrete classes that return at the first line, so the parse was
running per resolved receiver site to be discarded immediately. Case 4 and Case
6 now hand over the string they already hold, and the folded-receiver helper
returns the recorded spelling rather than parsing it.

**One question gates the whole instantiation apparatus.** Inside the closure
walk, the graph-id lookups now hang off "is the supertype's instantiation
known?" — false for every non-generic receiver and for every language that
captures no heritage arguments, which is what makes those walks cost exactly
what they cost before #2912.

Also lifted the argument-route choice in `pass5CollectReferences` out of a
nested ternary into a named `heritageTypeArguments`, where the reason the
explicit sub-tag wins over the anchor text can be stated once.

* test(scope-resolution): cover generic interface dispatch in Kotlin and Go (#2912)

Extends the #2912 dispatch coverage past C#/Java/TypeScript. No production
code changes — the derivation is language-agnostic by construction
(`heritageTypeArguments` reads the heritage anchor's own spelling), so the
question was only which languages actually reach the filter.

Kotlin rides the shared heritage pre-pass; Go reaches the same filter from
the other side, matching implementors structurally while the receiver's
`Validator[string]` spelling carries the instantiation. Both are confirmed
to prune the mismatched implementor.

Each language gets a NON-GENERIC control asserting the fan-out still reaches
every implementor. Without it the `not.toContain` assertion passes just as
well when a language emits no dispatch edge at all — which is what Dart,
Python and Rust were measured doing for this receiver shape, generic or not.
They are deliberately not asserted on here: a "filtered correctly" test over
a path that never fans out measures nothing.

* test(bench): re-baseline the Rust and Dart capture fingerprints for #2912

The Rust trait-impl and Dart heritage capture changes this branch makes are
additive TEXT on existing matches — each carries the instantiation the clause
was written with — so they drift the scope-capture digest without adding or
removing a match. The baselines were never re-measured when those captures
landed, which left `measure.mjs --check` red on this branch independently of
the merge.

Re-measured rather than hand-edited. Rust's capture_groups_fp (3556) and
fixture_count (202) are unchanged across the move, which is the evidence that
this is digest drift and not a capture-set regression. The other 13 languages
are byte-identical; 15/15 pass.

* refactor(scope-resolution): quality pass over the #2912 change

Cleanup only — no behavior change. Findings from a four-angle review (reuse,
simplification, efficiency, altitude), applied where they were verified.

Reuse / duplication:
* `stripTrailingCallSuffix` was a second copy of `matchingOpenParen`'s backward
  balanced-paren scan. Both now live in `template-arguments.ts` beside
  `balancedTailList`, for the reason that helper was shared in the first place:
  two copies of a scan this fiddly are free to disagree.
* The two call-return arms of the compound fold repeated the same four-part
  expression character for character; they share `classOfReturnType` now, the
  return-type twin of `classOfDeclaredType`, which keeps the "look up by
  rawName, report the erased application" pairing in one place.
* `pipeline/run.ts` implemented first-writer-wins twice — once in the pre-pass
  and once in the provider sink. One store, one sink, one rule; the pass keeps
  its `Set<string>` return and the callable-flow-only arm stops building an
  empty map to satisfy a widened return shape.

Simplification:
* `subtypeParametersComplete` dropped a disjunct that could never decide: every
  `subDef` reaching it comes out of the same loop that sets
  `languageCapturesTypeParameters`, from exactly those defs.
* The heritage-argument lookup asked "is the supertype's instantiation known?"
  three times; `superGraphId` now gates the block once.
* `TypeArgumentResolver` and `HeritageInstantiationResult` un-exported — no
  consumer outside their module.

Efficiency (all on the per-site dispatch walk):
* `resolveSupertypeArgument` captures only the site, so it is built once per
  site instead of once per subtype visited; the subtype's scope id is looked up
  once per subtype instead of once per argument position.
* `erasedTypeApplication` no longer runs on every fold hop through a call — the
  spelling is built only once the lookup has found a class, since it is
  discarded otherwise.
* `normalize`+`compact` computed once per side rather than twice.
* Regex literals and the identity `normalize` fallback hoisted to module scope.
* C# `System.` prefix stripped with `startsWith`/`slice` instead of a regex.

Verified: tsc clean, build clean, 1994 scope-resolution unit tests, 171
generic-dispatch + generic-field-receiver integration tests, 15/15 capture
bench fingerprints unchanged.

* fix(scope-resolution): close the generic-dispatch review findings (#2912)

Addresses the gitnexus-check review on #2939.

A repeated type variable was rebound rather than unified: `class C<T> :
Pair<T, T>` accepted a `Pair<string, int>` receiver, with `T = int` silently
replacing `T = string` and the bogus substitution carried to the next hop.
It now unifies, and prunes only on the same positive evidence the concrete
path demands — an undecidable repeat keeps the target with no binding.

A type PARAMETER of the declaration enclosing either side is now recognised
and never compared. `subtypeParametersComplete` is evidence about the
SUBTYPE's parameter list and says nothing about a `T` written at the call
site, so `void Run<T>(IValidator<T> v) { v.Check(x); }` pruned every
implementor: unbounded, `T` grounds to nothing; bounded, it grounds to its
BOUND. Both read as a difference of type. That is the missing-edge failure
this filter is built to avoid, and it is the common dependency-injection
shape in C#, Java and Kotlin.

Making that recognition reliable is why generic METHODS now capture
`@declaration.type-parameters` in C#, Java and Kotlin — TypeScript already
did, which is why its generic functions never had the defect. The capture
feeds the existing `bindsTypeParameter` guard, so a method-level `T` also
stops resolving to a same-named class in every other lookup.

C# alias normalization additionally strips the `global::` qualifier, which
`import-decomposer` already unwraps elsewhere: `global::System.String` read
as unequal to `string` and pruned a live implementor.

The C# captures golden fixture is regenerated for the new capture; the
extractor reads `@declaration.type-parameters` generically, so no reader
changed. SCHEMA_BUMP 64 already covers these capture changes.

* fix(scope-resolution): close the two remaining gitnexus-check findings (#2912)

`balancedTailList` counted ONE bracket family, so a crossed pair slipped
through: scanning `Foo<Bar]>` it never sees the `]`, reaches the final `>` at
depth zero, and reports `Bar]` as a balanced argument list — which
`typeApplicationArguments` then splits and `erasedTypeApplication` rebuilds a
spelling from. It now tracks a stack of expected closers, so every closer must
match the opener it actually closes and a crossed pair declines to `undefined`,
the "unknown" both callers already fail open on. Well-formed mixed nesting
(`List<Dict[a, b]>`) is unaffected.

C# `normalizeTypeArgument` stripped `System.` from every qualified spelling, so
`System.Custom` answered `Custom` and compared equal to an unrelated `Custom`
elsewhere in the workspace. The strip is now earned: a keyword answers from the
alias table first, and the qualifier is dropped only when what remains IS a
predefined type. `System.Custom` is returned as written and goes to the identity
comparison instead — the step that can actually tell two declarations apart.
`global::System.String` still meets `string`.

Both are pinned by unit tests, including the well-formed mixed nesting and the
`global::`-qualified ordinary type that must keep its qualifier.

* docs(csharp): record why a shadowed `String` keeps its implementor (#2912)

Answers a review finding rather than changing behavior.

A workspace may declare its own type named `String`, shadowing the BCL simple
name, and the alias table then reads `IValidator<String>` as the `string`
instantiation and keeps that implementor. That is the SAFE direction, not an
oversight: pruning instead would rest on the belief that two spellings differ,
which is the missing-edge failure `generic-instantiation.ts` exists to avoid.

Resolving rather than normalizing cannot settle it either — the identity
comparison needs a `definitionId` from both sides, and a built-in name carries
none, so "built-in versus workspace-declared implies different" would be a new
prune with no positive evidence behind it. The cost is one surplus edge for that
pair, which is exactly the pre-#2912 fan-out and no worse.

* refactor(scope-resolution): pair the receiver spelling with the class structurally (#2912)

The fan-out needs the spelling a receiver position was typed from, because the
class the fold returns has lost the generic arguments. That was carried by a
PASS-LEVEL mutable holder, written by every declared-type lookup anywhere in the
fold and read back through a def-id coincidence check, with the holder cleared
by hand before each call site. Three things were load-bearing and none were
enforced:

* the reset had to be remembered at every call site. It was not: the Case 3b
  retry (`rawName` then `rawName + '()'`) reset once, BEFORE the first attempt,
  so a spelling reported by the attempt that failed could be attributed to the
  one that succeeded.
* the holder outlived every resolution, so a site that resolved through a route
  reporting nothing could read the previous site's spelling if the def ids
  happened to line up.
* the pairing itself was inferred from "whichever lookup reported last", not
  from the fold's own bookkeeping — losing branches (an MRO walk that moved on,
  a step later folded past) report too.

`foldReceiverChain` already had the answer and threw it away: its final
`FoldState` holds `def` and `declaredType` produced by the SAME step. It now
reports that pairing last, so the structural route is the one that stands.

`resolveCompoundReceiverTyped` returns `{def, declaredSpelling}` and owns a sink
created and read within the single call, which is what removes the reset
discipline — a local cannot be forgotten, and each of the two retry attempts
carries its own. The def-id guard stays as the check that a report names the
class actually returned.

Behavior is unchanged: 1975 scope-resolution unit tests, 177 generic-dispatch
and generic-field-receiver integration tests.

fix(java): materialize record component accessors (#2936)
* fix(java): materialize record component accessors

* fix(java): ignore receiver params in record accessor arity

* fix(java): address record-accessor review findings (#2917)

Five findings from the tri-review of #2936.

P1 — a synthesized callable evicted a source-written one from the method map.
`getMethodInfo` keyed its per-class map by `name:line`, but a callable that is
SYNTHESIZED at a position that is not its own declaration shares its owner's
line: a record's implicit accessor is minted at the component, and a C# 12
primary constructor at the owner's `parameter_list`. Both are appended last by
their extractor, so on a single line the synthesized entry overwrote the
explicit method's MethodInfo and both definitions collapsed onto one id —
`record P(int x, int y) { int x(int s) {...} }` lost `P.x#1` and rebound the
arity-1 call to the zero-argument accessor. Adds a required `MethodInfo.column`
and keys the map by `name:line:column` through a single `methodInfoKey` helper.
Required, not optional: an absent column would key an entry no lookup could
reach — a silent, whole-language loss of enrichment instead of a compile error.
All three lookup sites move together; the file's own lockstep docblock warns
that a half-applied change loses caller edges silently rather than dangling.
This also fixes the same collision in C#, which never touched record code.

Degenerate component names no longer mint a node. tree-sitter's zero-width
MISSING recovery token satisfies `name: (identifier)`, so `record M(int x, y) {}`
minted an empty-named Method whose returnType was the neighbouring `y`; and the
grammar admits `underscore_pattern` in the same field, which the query rejected
but the scope path accepted, so `record R(int _) {}` left a scope declaration
with no node behind it. One `isRecordComponentName` predicate now gates all
three emitters — query suppression, scope synthesis, and the method extractor —
so they cannot drift apart again.

Component annotations reach the implicit accessor (JLS 8.10.3 / 9.7.4) by
reusing the shared `extractAnnotations` helper. Deliberately over-approximate
and commented as such: `@Target` lives in another file and parsing is per-file.

`explicitZeroArgAccessorNames` is memoised per record node. It was rebuilt on
every component capture — O(components x body members) for one record, measured
at ~4x per 2x input — while the scope path already hoisted the identical call.

Docs: the `java-local-types` baseline now stores the `capture_groups_fp` its own
note cites, the SCHEMA_BUMP ledger no longer claims a v65 that nothing holds,
and `shouldSkipDefinitionCapture` documents that `defaultLabel` may be ignored.

Scope-capture fingerprints are unchanged (`measure.mjs --check` PASS, 15
languages): the bench corpus contains no degenerate components, so the new
predicate is inert on it. SCHEMA_BUMP stays 67 — this branch's existing claim
already covers the changed worker output; re-check it against origin/main before
merging.

* docs(ingestion): reunite the overload-suffix JSDoc with typeTagForId

The block describing the `~type1,type2` same-arity discriminator was stranded
above `buildCollisionGroups` when that function was inserted between it and the
`typeTagForId` it documents (#658). Adding `methodInfoKey` in this branch parked
it directly above yet another unrelated function, which gitnexus-check flagged.

Moves the comment down to the function it describes. No behaviour change.

fix(mcp): stop scaling the detect_changes query with the diff's hunk count (#2915) (#2930)
* fix(mcp): map diff hunks to symbols without per-hunk OR conditions (#2915)

`detect_changes` folded one `(n.startLine <= $hunkEndI AND n.endLine >=
$hunkStartI)` pair per diff hunk into a single WHERE clause, one query per
changed file. A machine-generated file (cache JSON, lockfile, golden fixture)
diffs at thousands of hunks with `-U0`, and the expression tree that produces
overflows LadybugDB's recursive evaluator copy on a TaskScheduler worker
thread: a bare SIGBUS with no error output where secondary threads get 512 KB
of stack (macOS), a swallowed 30s query timeout where they get more (Linux),
which the CLI then printed as "No changes detected." with exit 0.

Coalesce each file's hunks into sorted, disjoint ranges and run the overlap
test in JS instead. Only ranges that overlap or abut are merged, so the union
covers exactly the lines the raw hunks covered. Query text and parameters are
now identical whether a file changed in 1 place or 100,000, and files are
queried in batches of 100 rather than one full node scan each.

Reproduced on Linux by running the engine with macOS-sized (512 KB) thread
stacks: 2,500 hunks passed, 3,333 and 4,000 segfaulted — matching the reporter's
macOS threshold table. After the change the same repo maps a 100,001-hunk diff
in 2.1s with no crash.

Also fixes a line-base mismatch the rewrite exposed: graph rows are 0-based
(#2377) while git hunk lines are 1-based, so the raw comparison shifted every
symbol one line up. An edit to a symbol's LAST line reported nothing changed —
a one-line function whose body was edited was invisible to the pre-commit gate.

* fix(cli): say when a detect_changes result is partial (#2915)

When a graph query fails, `detect_changes` swallows the error, sets
`partial: true` and leaves the counts at zero (#2283). The CLI formatter never
read that flag, so a degraded run printed "No changes detected." and exited 0 —
the pre-commit safety gate reporting a clean bill of health for a check that
did not complete. Print the partial note in both the empty and non-empty
branches.

Also restore the `Symbol` placeholder for rows whose label came back as an
empty string: the changed-symbol mapping now keeps `''` instead of dropping it
to undefined, so the formatter needs `||`, not `??`.

* refactor(mcp): bound the hunk→symbol query and simplify the overlap helpers (#2915)

Cleanup pass over the #2915 fix. No change to which symbols detect_changes
reports, except that a node matched by two changed paths is now reported once.

* Push a per-file [lo, hi] span into the query. Coalesced ranges are sorted and
  disjoint, so a file's whole touched span is free, and the engine can drop the
  symbols outside it instead of shipping every row in the file across the native
  boundary. Measured on a 400-file batch against a 25k-node index: 546ms/13,870
  rows before, 84ms/1,555 rows after, identical kept set. Depth stays constant
  (two comparisons per file, not per hunk), so #2915 cannot come back — the JS
  test still rejects symbols landing in the gaps between hunks. The struct-list
  parameter was verified against @ladybugdb/core 0.18.3 and 0.19.1.
* Convert hunks into the graph's 0-based space once, at the point they are
  grouped, with the existing `toZeroBasedLine`. Every comparison downstream is
  then base-neutral, and `toDisplayLine` goes back to being what its doc says it
  is: an MCP response-boundary converter, not a filter input.
* Deduplicate matched nodes by id. `ENDS WITH` is a plain string suffix, so a
  diff touching both `README.md` and `pkg/README.md` counted the same node
  twice (169 duplicates in 13,870 rows on a real 400-file diff). Pre-existing,
  free to fix now that the rows are shaped in one place.
* Drop the positional `?? sym[N]` row fallbacks in this block.
  `executeParameterized` returns `getAll()` rows, which are alias-keyed objects,
  so the fallbacks were dead — and they coupled the mapping to RETURN column
  order, which is what made adding a column a renumbering exercise.
* Build the path→hunks map in one pass, so "every value is coalesced" holds at
  every point rather than being repaired by a second loop. Simplify
  `coalesceHunks` (the length<2 branch and the sort tiebreaker changed nothing)
  and state `hunksOverlapRange` as a standard half-open lower bound.
* Document `partial` in the detect_changes tool description. The CLI now prints
  it, but the MCP client — the main consumer of the pre-commit gate — was
  getting the flag as an undocumented raw key.
* Tests: pin the query text as identical for a 1-hunk and a 3,000-hunk diff
  (replacing a magic length bound), pin the 0-based bounds parameter, pin the
  dedup, and fold two near-identical row mocks into one helper. Temp dirs now
  come from the shared pool helper, whose cleanup is per-directory and
  Windows-lock aware.

* feat(mcp): bound and batch the hunk→symbol query, and anchor its path match (#2915)

Follow-up review pass on the #2915 fix, implementing every remaining finding.

* Push a per-file `[lo, hi]` span into the query. Coalesced hunks are sorted and
  disjoint, so a file's touched span is free, and the engine drops the symbols
  outside it instead of shipping every row in the file across the native
  boundary. Measured on a 25k-node index, 400-file batch: 546ms/13,870 rows
  before, 84ms/1,555 after, identical kept set. Depth stays constant (two
  comparisons per file, not per hunk), so #2915 cannot return. The struct-list
  parameter was probed against @ladybugdb/core 0.18.3 and 0.19.1 first; the
  index-subscript form `$paths[i]` does not parse.
* Anchor the path match: `n.filePath = b.path OR n.filePath ENDS WITH b.suffix`
  where suffix is the path with a leading separator. A bare `ENDS WITH` is a
  plain string suffix, so a diff touching `lib/a.py` also reported a symbol from
  an indexed `src/mylib/a.py` — a file the diff never touched. This is the form
  `explain` already uses. Pinned by an integration test against a real engine
  (it fails 3/3 with the un-anchored predicate).
* Run batches a few at a time. `executeParameterized` checks a connection out of
  the 8-connection per-repo pool for the duration of a query, so parallel calls
  never share one — the same reason ~15 other queries in this file already run
  under `Promise.all`. `allSettled`, so one failed batch degrades the result to
  `partial` instead of discarding the batches that succeeded beside it.
* Deduplicate matched nodes by id, and count `changed_files` as distinct paths:
  a path can appear twice in one diff (a rename reported alongside an edit).
* Cap the listed symbols at 1,000 with `symbols_truncated: {listed, total}`.
  A repo-wide diff otherwise puts an unbounded array in one MCP payload — the
  CLI has `--limit`, an MCP client has nothing. Counts are never capped, so the
  risk level and the CLI's "... and N more" still see the true total.
* Extract `chunk` / `mapBatches` / `LBUG_QUERY_BATCH_SIZE` into
  `core/lbug/query-batch.ts`. Every query built from a caller-sized array has
  this ceiling; the shape now has one name and the measured batch size is
  recorded where it is defined rather than in three constants under three names.
* Move hunk grouping and the 0-based conversion into `coalesceHunksByPath`, at
  the parse boundary. `parseDiffHunks` stays faithful to git (1-based, like the
  `@@` headers it reads), consumers compare graph-native values, and the
  conversion is unit-testable instead of living in the backend.
* Document `partial` and `symbols_truncated` in the detect_changes tool
  description — the MCP client is the main consumer of the pre-commit gate and
  was getting both as undocumented raw keys.

* refactor(core): batch every remaining repo-sized query list (#2915)

`detect_changes` was not the only place building query text from a
caller-sized array. `core/wiki/graph-queries.ts` interpolated the whole file
list of a module into four `IN [...]` literals, growing the query with the
repo — flat breadth rather than the nested depth that crashed #2915, but the
same unbounded shape, and the one the repo's own `DELETE_FILES_CHUNK_SIZE`
precedent already chunks elsewhere.

All four now run one query per batch and merge in JS. The membership arms need
care, and each is documented where it happens:

* `getIntraModuleCallEdges` batches the caller arm only. A per-batch callee arm
  would drop a call from batch 0 to batch 2, both inside the module, so that
  predicate moves to JS against the whole set. Results are now sorted: the
  single-query form had no ORDER BY, and batch order would hand the entire
  30-edge window `formatCallEdges` keeps to the first 100 files (#2787).
* `getInterModuleCallEdges` keeps the SAME batch list in its `NOT` arm. That is
  sound — a file outside the module is outside every batch — and it preserves
  the null handling: `NOT null IN [...]` is null, so the original dropped edges
  to a node with no filePath, where a JS-only `!has(undefined)` would admit
  them. ORDER BY and LIMIT move to JS because a per-batch limit would cut rows
  before the cross-batch membership filter ran.
* `getProcessesForFiles` keeps `LIMIT` inside the batch: `stepCount DESC, id` is
  a total order, so a process in the global top-N is in its own batch's top-N.

Also adopt the shared `chunk()` at the hand-rolled slice loops in
`lbug-adapter.ts`, `embeddings/http-client.ts` and `run-analyze.ts`. The loops
whose index fed a progress callback or an error message use
`chunk(...).entries()`, which removes the `i / SIZE` and `Math.floor(i / SIZE)`
arithmetic rather than reproducing it. No batch size changed.

One trap that survived tsc and is worth naming: after renaming a loop variable
away from `chunk`, a leftover `chunk.length` silently resolved to the imported
FUNCTION's arity, reporting `chunkSize: 1` for a 200-path batch. Only
`lbug-query-importers-batch`'s exact-value assertion caught it.

* refactor: name the line-base conversions and share the symbol line (#2915)

The 0-based-graph vs 1-based-elsewhere rule was open-coded in five places with
the reasoning living only in comments — the same rule that, applied by hand and
skipped once, hid every last-line edit from `detect_changes`.

* Add `toOneBasedLine` beside `toZeroBasedLine` in `ingestion/utils/line-base.ts`
  so the module owns both directions, and adopt it at the four CFG/PDG join
  sites in `pdg-impact.ts` and the two in `local-backend.ts`. This is NOT
  `line-display.ts`'s `toDisplayLine`, which is documented as a response
  boundary converter with an `undefined` passthrough; the joins need
  arithmetic, and the guards that produce `Number.NaN` for an absent line are
  kept verbatim.
* `http-route-extractor.ts` probed graph spans with a bare `line - 1` and a
  20-line comment. It calls `toZeroBasedLine` now; the `?? pick(line)` fallback
  arm is untouched, so which node is picked cannot change (the clamp differs
  only for a negative line, which no emitter can produce).
* Extract `formatSymbolLine`: `detect-changes-format.ts` and `eval-server.ts`
  rendered the same `type name → filePath` line. One behavior note — the two
  were not byte-identical, and eval-server had no placeholder on `name`, so a
  definition with an empty name rendered the literal `undefined` and now
  renders `?`. Both `definitions[]` shapes set name from a graph row, so this
  is unreachable in practice, and printing `undefined` into LLM-facing output
  is the bug, not the intent.

`||` (not `??`) in the placeholders is deliberate and documented: a node label
can come back as an empty string and still needs the placeholder.

* perf(wiki): bind the module file list instead of splicing it into the query (#2915)

The wiki's four `IN [...]` sites interpolated every file of a module into the
query text, so the text grew with the repo — the shape that overflowed
LadybugDB's recursive evaluator copy in `detect_changes`. The previous commit
chunked them, which worked but cost real complexity: the callee arm had to leave
Cypher and be re-implemented in JS, DISTINCT had to be re-established across
batches, and ORDER BY/LIMIT had to move to JS so a per-batch window could not cut
rows the cross-batch filter still needed.

Binding the list as a parameter removes the reason for all of it. The text is
constant at any list length, and measured against a real index a bound list is
~3x faster than the equivalent literal (5,000 items: 139ms vs 459ms; 20,000:
598ms vs 1,686ms). Every predicate goes back into Cypher, including the `NOT ...
IN` arms whose null handling is load-bearing — `NOT null IN [...]` is null, so a
callee with no filePath is dropped by the engine, where a JS membership test
would have admitted it.

Verified on this repo's own index: a 2,000-path bound list returns 14,856 rows in
877ms.

Also collapses the per-process step query into one grouped `p.id IN $ids` fetch —
105ms to 13ms for 20 processes — and drops `fileListLiteral`, `callEdgeKey`,
`compareProcessHeaders` and the batching loops with it. `compareStrings` was a
byte-identical re-roll of `compareCodeUnits` (src/lib/utils.ts), including its
#2787 rationale; it now calls the shared one.

Intra-module edges are sorted where the original had no ORDER BY: `formatCallEdges`
keeps only the first 30, and an unordered cut keeps a different subset per machine.

* refactor(core): one home for batching, and a backstop for the shape that crashed (#2915)

`chunk` moves to `src/lib/utils.ts`, the repo's generic-utility home: it is an
array helper, and leaving it in `core/lbug/query-batch.ts` made an HTTP
embedding client import batching from the graph-DB namespace. `query-batch.ts`
keeps what is actually about queries — the measured `LBUG_QUERY_BATCH_SIZE`, the
concurrency helper, and the ceiling — and now documents the preference the wiki
change proved: bind the list as a parameter first, chunk only when you cannot.

`mapBatches` becomes `mapConcurrent`: nothing about it is batch-specific, and it
now has non-query callers. Its body is a per-item try/catch plus `Promise.all`,
so ordering comes from the primitive rather than from unwrapping a settled
union. The wave barrier stays — measured against a rolling window it is 538ms vs
532ms on a 1,000-file diff, whose per-batch times spread only 1.35x.

Adopted at the loops that were still hand-rolled: `file-hash.ts`,
`cluster-enricher.ts` (its progress callback now accumulates `batch.length`
instead of clamping an index), `filesystem-walker.ts` and `language-config.ts`
(wave scheduling with `allSettled`, which is exactly `mapConcurrent`).
Deliberately not adopted, each for a stated reason: the analyzer-identity probe
runs as a standalone `node -e` script with no module resolution; the embedding
sub-batch loop slices two parallel arrays and breaks early;
`walkRepositoryPaths` reports progress from inside each wave, which
`mapConcurrent` cannot express.

`warnIfQueryTextUnbounded` is the backstop: #2915 died in native code with no
message, and a query built by concatenating a caller-sized list is the shape
that gets there. Wired at both execution chokepoints (`pool-adapter`'s
`executeParameterized`, `lbug-adapter`'s `executePrepared`/`streamQuery`; their
`executeQuery` siblings delegate and are covered once). It never throws — a long
query the engine can actually run must not start failing on a heuristic — and it
is deliberately absent from the raw write path, where a node's `content` is
inlined and a large source file would warn legitimately.

* refactor(mcp): name the path-match rule, and key detect_changes by node id (#2915)

* `path-predicate.ts` names the three ways a caller's path can match a stored
  `filePath` — `exact`, `pathSuffix`, `fragment` — instead of each call site
  copying whichever idiom its neighbour used. A bare `ENDS WITH` is a plain
  string suffix, which is how a diff touching `lib/a.ts` came to report a symbol
  from `src/mylib/a.ts`; the loose `CONTAINS` sites are loose ON PURPOSE (a user
  hint of `src/mcp` should match a directory fragment), and naming the modes is
  what lets a call site choose rather than inherit.
* `detectChanges` kept four structures over one row set — an array, a dedup Set,
  an id list and an id→name Map — that had to stay in sync by hand. One
  id-keyed Map is all of them; insertion order is preserved, so every output is
  byte-identical.
* `symbols_truncated: {listed, total}` becomes `truncated: true`, the key
  `explain`/`pdg_query`/`trace` already use. The true total was always in
  `summary.changed_count`, so the nested object said nothing the existing
  vocabulary could not.
* `GraphLineRange` is now a distinct type from `DiffHunk`: they carry the same
  two fields in different bases, and mixing them IS #2377. The name means a
  1-based hunk cannot reach `hunksOverlapRange` without a conversion between.
* `coalesceHunksByPath` accumulates raw ranges and coalesces once per path
  rather than re-sorting on every occurrence.
* `chunk` adopted at this file's own five loops — the point of extracting it —
  including two locals named `chunk` that shadowed the import. That shadowing is
  not cosmetic: it is how a leftover `chunk.length` silently became the
  function's arity earlier in this branch.

One bug caught by the real-engine integration test and worth naming: Cypher
comments are `//`, not `--`. A `--` comment inside the query string made
LadybugDB reject the whole query at PREPARE, which `detect_changes` swallows
into `partial` and renders as "No changes detected." Every mocked unit test
passed. Prose stays out of query strings.

* refactor(test): share the git-repo bootstrap, and move the shared formatter out (#2915)

`formatSymbolLine` lived in `detect-changes-format.ts` but is rendered by
`eval-server`'s query formatter too, so a `query` formatter imported from a
`detect_changes` module. It moves to `src/cli/format-symbol.ts`; both callers
import it from there. The `||`-not-`??` fallbacks stay documented — a node label
can come back as an empty string and still needs its placeholder.

`test/helpers/temp-git-repo.ts` gives `initGitRepo(dir, identity?)` and
`commitAll(dir, message)` to the ~10 test files that hand-rolled the same
`git init -q` + two `git config` + `add -A` + `commit` sequence. It takes a
directory and never owns one, matching `temp-dir-pool.ts`'s split of lifecycle
from seeding; the identity is a parameter because the existing consumers
genuinely disagree about it, and each keeps exactly what it configured. Four
files stay hand-rolled for stated reasons — pinned author dates for a
deterministic digest, remote handling, `--allow-empty`, and the `-c key=value`
form that never persists to the repo.

Test trims: the `formatSymbolLine` fallback cases collapse into one `it.each`
table (the case pinning that BOTH consumers emit the helper's exact line stays —
no table row can express it); two `line-base` cases that were compositions of
their neighbours go; and `detect-changes-path-anchoring` runs its
`detect_changes` call once in `beforeAll` instead of three times, keeping the
three named failures.

* perf(mcp): filter the batched hunk query before the engine materialises (#2915)

`UNWIND $bounds AS b MATCH (n) WHERE …b…` compiles to a CROSS_PRODUCT whose
build side is a RESULT_COLLECTOR over the whole filtered node table: only the
`n`-only predicates get pushed below the accumulate, so neither the anchored
path match nor the [lo, hi] span could reduce the scan. Measured at 1M nodes:
+242 MB for one batch and +922 MB for the four concurrent ones, paid even for a
one-file diff — and at a 268 MB buffer pool the query died with `Buffer manager
exception` where the old per-file query completed, landing in `partial:true` +
`changed_count:0`, the #2915 false clean by another route.

Adding the batch-wide, `b`-free disjunction as a redundant leading conjunct
lets the planner push it below the accumulate: EXPLAIN now shows it as FILTER[2]
directly under SCAN_NODE_TABLE[0]. It is a provable superset of the correlated
predicate, so it cannot drop a row the correlated filter keeps. 10x less memory,
~20% faster, identical result sets.

Also in detect_changes:
- Sort rows on (filePath, startLine, id) before the 1000-symbol cut. The cut was
  slicing engine row order — measured 5 distinct orders across 8 runs on one
  connection, the #2787 class this branch fixes 200 lines away in the wiki.
- Chunk `symIds`, the one caller-sized list left unbatched: 500k ids measured
  4.0 GB RSS. Binding keeps the query TEXT constant, which is all the unbounded
  guard measures, while the bound VALUE stayed repo-sized.
- Prefer exact path equality and widen to the anchored suffix only for paths
  that matched nothing, so a root README.md stops reporting pkg/*/README.md.
- Report `risk_level:'unknown'` rather than 'low' when a query was swallowed.
  A degraded pre-commit gate must not read as an all-clear.
- Pass --no-ext-diff --src-prefix=a/ --dst-prefix=b/. `diff.noprefix` in a user's
  gitconfig makes git emit `+++ f.py`, which parseDiffHunks cannot match, so every
  run printed "No changes detected." and exited 0 before any query ran. A diff
  that parses to zero files now raises `partial` instead of the clean branch.
- `labels(n)`, not `labels(n)[0]`: labels() returns a scalar string here, so the
  subscript was always '' and `type` never carried a label.
- Validate IMPACT_MAX_CHUNKS. The chunk() adoption turned an entry condition into
  an exit condition, so a non-numeric value ran every chunk instead of none.
- Record why four-way concurrency is safe here, and scope the arm64 sequential
  comment to the query it was written for (#496).

* fix(cli): fail the detect_changes gate instead of exiting 0 when it degrades (#2915)

The secondary half of #2915 was that a swallowed query failure printed
"No changes detected." and exited 0, so a shell pre-commit gate passed on a
broken analysis. This branch added the PARTIAL text. It did not change the exit
status, so `gitnexus detect-changes && git commit` still proceeded.

`detectChangesCommand` passed a STRING to `output()`, and `output()` sets a
failing code only for an OBJECT carrying `error` — under a comment calling
itself "the one place that keeps scripted callers honest". A string never
matches, so this command opted itself out of the only mechanism the file
provides. It was broader than `partial`: the formatter also renders a backend
`{error}` payload as text, so hard failures exited 0 too.

Fixed narrowly in `detectChangesCommand`, following the object-first shape
`checkCommand` already uses, rather than widening `output()`'s shared contract —
every one of its other seven callers already passes an object and is unaffected.
One code for both `error` and `partial`: `&&` only distinguishes zero from
non-zero, and a softer code for `partial` would invite `|| [ $? -eq 2 ]`
exemptions that reopen exactly this hole.

`truncated` deliberately stays exit 0 — only the listing is capped, while the
counts and risk are computed over the full set, so the verdict is sound and
failing on it would fire on every large-but-healthy diff.

Also wires `truncated` through the formatter, which this branch had left as a
producer-only flag while `partial` went end to end, with the note in both
locales and no count of its own so the existing "... and N more" line stays the
sole numeric report.

* fix(wiki): restore step order and symbol labels, and cut the edge list in Cypher (#2915)

Found by running the queries against a real engine, which nothing did before:
this branch's regrouped `withSteps` returned step traces OUT OF ORDER.
`ORDER BY pid, r.step` combined with `WHERE p.id IN $ids` silently drops the
second sort key — `proc_1_incrementalupdate` came back 2,7,1,3,4,5,6.
`ORDER BY step` alone is correct, and so was the pre-branch per-process query,
so this was introduced by the batching. `formatProcesses` prints
"${s.step}. ${s.name}", so every module and overview page was getting scrambled
execution traces. The mocked suite passed 112/112 before and after.

`labels(x)[0]` is always the empty string: labels() returns a scalar string and
the subscript is 1-based over its characters ([1] is "F"). `prompts.ts` renders
"${s.name} (${s.type})", so all 5,027 exported symbols reached the LLM as
"name ()".

`getIntraModuleCallEdges` shipped every edge to use 30 — measured 18,299 rows
and 851 ms with all 2,079 paths bound, against 30 rows and 94 ms with
ORDER BY + LIMIT in Cypher, which the sibling `getInterModuleCallEdges` twenty
lines below already did. The determinism fix (#2787) was right; the placement
was not. `compareCallEdges` goes with it — it was intransitive when a name was
null or empty, so `Array.sort` was input-permutation dependent, i.e. the
nondeterminism it was added to remove.

Deletes the positional row ABI this branch newly documented. The vendor
declaration is `getAll(): Promise<Record<string, LbugValue>[]>` — string keys
only — and `row[0]` probes back `undefined`; the same PR deleted ~30 identical
fallbacks from local-backend.ts. They were already stale here: `withSteps`
prepends `p.id AS pid`, so `toProcessStep` was reading the pre-branch layout.
Rows are now typed by alias, so renaming an `AS` is a compile error. `??` for
`||` so a step of 0 or an empty label keeps its own value.

Tests: a real-engine integration suite covering all seven exported queries
(PREPARE included — the trap that shipped a `--` comment on this branch), and
the four holes that let the ordering bug through — a vacuous order assertion, a
LIMIT never reached by a 2-edge fixture, a fake that returned rows pre-ordered
and ignored ORDER BY, and a hardcoded `type: 'Function'` that hid labels().

The step-ordering fixture is empirically sized: 2 processes never reproduced the
bug, ~400 step edges was intermittent, 710 (20 processes x 26-45 steps) hit
11 of 11 runs. Seeded descending and interleaved so no grouping looks sorted by
accident.

* refactor: put the shared helpers where their callers are, and make their contracts true (#2915)

`mapConcurrent` moves to lib/utils.ts beside chunk(). Nothing about it is
query-specific and it already had filesystem callers, while its docstring
justified concurrency safety through the per-repo connection pool — an argument
that does not apply to fs.readFile. This is the precondition the branch's own
commit message stated ("it now has non-query callers") and then did not apply.
LBUG_QUERY_BATCH_SIZE and warnIfQueryTextUnbounded genuinely are query-specific
and stay.

`pathMatch`/`PathMatchMode` deleted: zero callers, and none of the three sites
its docstring cited were migrated, so the tree carried the abstraction and the
copies it was written to replace. `pathSuffixOf` stays and the module now
documents the anchoring rule it actually implements.

Contracts that were not true:
- QUERY_TEXT_CEILING_BYTES was compared against `cypher.length` — UTF-16 code
  units, not bytes — so non-ASCII query text was undercounted and the reported
  KB was wrong. Buffer.byteLength now, behind a `length * 3 <= ceiling` early
  return so only text over ~21 KB pays for the count.
- chunk(items, NaN) returned [[]], against a docstring promising never to return
  an empty slice, and mapConcurrent's Math.max(1, NaN) propagated it — which
  would have resolved [] for non-empty input with no error, read as "no results"
  by every call site.
- GraphLineRange claimed a 1-based hunk could not reach hunksOverlapRange
  without a conversion, but it was structurally identical to DiffHunk so tsc
  accepted one with no diagnostic, and coalesceHunks<T extends GraphLineRange>
  actively laundered the base while its accumulator was still DiffHunk[]. The
  useless generic is gone and a one-line phantom on each interface makes the
  claim real; a bare {startLine, endLine} literal still satisfies both, so no
  construction site needs a cast.

Pure deletions no longer vanish. A -U0 deletion emits `+N,0`, which
parseDiffHunks dropped, so the file survived with no hunks, no query ran, and
detect_changes reported `changed_files:1, changed_count:0, risk_level:'low'` —
"No changes detected." for a commit that deleted a function. A unified diff
spells an empty range as the line before it, so the anchor is line N alone:
a symbol containing the deleted text also contains N, while extending to N+1
would claim a symbol that merely starts after the gap — the widening
coalesceHunks guarantees it never does.

* docs: say that a partial or truncated detect_changes is not a clean gate (#2915)

The gate itself now fails loudly, but the instructions every agent reads still
described a zero as a result. Fixed at the source: AGENTS.md's gitnexus block is
generated from a template in cli/ai-context.ts and injected into every user's
repo, so the sentence goes there and AGENTS.md/CLAUDE.md are regenerated through
the real code path (which also picks up a pre-existing `analyze --index-only`
drift the committed docs were behind).

That block is under a test-enforced size cap with 30 characters of headroom, so
the 144-character clause was paid for in the same currency: the header
exhortation, which the Always Do list restates as MUSTs with commands, and a
verbatim repeat of the detect-changes command in the regression-compare example.
3549 of 3552. Worth noting for whoever adds the next line — #2899 replaced an
absolute cap with a 0.65 ratio to let "a legitimate clause fit without
ceremony", but set the ratio flush against the block's then-current size, so it
is a ratchet with no ratchet.

The canonical block does not make the skills redundant: three of the four
install channels ship skills without touching AGENTS.md, --skip-agents-md does
the same in-repo, and a user-trimmed gitnexus:keep block legitimately has no
Always Do section — in those repos the skill file is the only carrier. Precedent
agrees: the risk:UNKNOWN rule is deliberately carried in both places. So one
sentence each in gitnexus-work (the commit gate), gitnexus-impact-analysis
(beside the UNKNOWN paragraph) and gitnexus-refactoring, whose post-hoc "verify
only expected files changed" is the worst of the three because a degraded result
makes it vacuously pass. gitnexus-taint-analysis is left alone: its audience is
always inside this repo, where the canonical block loads.

All copies mirrored to npm, plugin and cursor. The cursor copies are condensed
checklists rather than byte-mirrors, so they carry the equivalent note placed
where it governs every detect_changes line in the file — and nothing tests that,
since standard skills are fragment-checked rather than byte-compared.

* refactor: break the seven small import cycles gitnexus check reports (#2915)

`check` reported 11 cycles. Five are paths inside a single 257-file strongly
connected component in core/ingestion (call-extractors / cfg visitors /
utils/ast-helpers), with a second 26-file component behind it — fixing those
paths would only make check print different ones, so both are left for their own
PR. This closes the seven that are genuinely separable, taking the graph from 9
strongly connected components to 2.

Six of the seven were one value import plus one `import type` edge. tsconfig
sets neither verbatimModuleSyntax nor isolatedModules, so those edges erase
entirely — the cut is a graph and readability change with no emitted-JS
difference. Each moved type went to a leaf module, with a re-export left behind
only where an importer outside the change actually needed it:

- cli/ai-context <-> cli/skill-gen: GeneratedSkillInfo -> cli/generated-skill.ts.
  One importer, no package export surface, so a clean move with no re-export.
- cli/analyze-config <-> cli/analyze (+core/run-analyze): AnalyzeOptions ->
  cli/analyze-options.ts. Re-export kept because a test imports it from
  analyze.js. run-analyze needed no edit — cutting the one type edge collapses
  the 3-file component into a DAG. Its own same-named AnalyzeOptions is a
  different interface and was deliberately not merged.
- ingestion/import-resolvers/types <-> ingestion/language-config: type-only in
  BOTH directions, so it had no runtime existence at all. ImportConfigs has no
  importers outside the pair and is the return type of loadImportConfigs, so it
  moved into language-config. Side effect worth having: the shared resolver
  types module no longer names a single language, which is an AGENTS.md rule for
  core/ingestion shared pipeline code.
- ingestion/di-extractors barrel <-> spring: DiResolver and the two match types
  -> di-extractors/types.ts, following the import-resolvers/types.ts precedent.
- scope-resolution/walkers <-> workspace-index: WorkspaceResolutionIndex ->
  workspace-index-types.ts. Re-export is load-bearing — 9 src importers, 4 test
  files, and a dynamic import() at contract/scope-resolver.ts. Moving the value
  isClassLike instead was rejected: ~15 value importers, and it is documented as
  a pair with isShapeLike.
- server/analyze-worker <-> analyze-worker-core: the WorkerMessage protocol ->
  analyze-worker-protocol.ts, a declarations-only leaf.

storage/branch-index <-> storage/repo-manager was the one genuine two-way
runtime cycle: branch-index called getStoragePaths/loadMeta, repo-manager used
branchSlug/BRANCHES_DIR. branch-index's header conceded the cycle and argued it
was ESM-safe because neither side calls across at module-evaluation time — a
guarantee resting on call ordering rather than structure. Folding
resolveBranchPlacement back the other way does not help, because
BranchSummary.stats is typed RepoMeta['stats'], so RepoMeta had to move either
way. Extracted storage/repo-meta.ts, a leaf importing only fs and path, holding
the metadata read primitives; repo-manager re-exports the public names so all
54 RepoMeta and 50 loadMeta importers are untouched. The moved block diffs
byte-identical against HEAD.

Verified beyond typecheck, because the worker entrypoint is the risky part and
nothing in the suite forks it: emitted analyze-worker.js still contains exactly
one runtime import, and forking the real worker over IPC boots it through
entry -> core -> protocol -> terminal-claim.

* refactor: apply the reuse, simplification, efficiency and altitude cleanups (#2915)

The one that mattered: the degradation exit code was fixed at the wrong depth.
`output()` has never inspected `partial` — it tests `error` only — so putting
the check in `detectChangesCommand` left every other tool exiting 0 on a
degraded run. `partial` is cross-tool vocabulary: query (enrichmentDegraded ||
ftsPartial), impact (!traversalComplete, perSymbolEnrichmentCapped) and the
mode:'pdg' envelope all emit it. A truncated impact traversal returns a short
caller set and an under-ranked risk, then exits 0 — so `gitnexus impact … &&
<edit>` proceeds, in the tool AGENTS.md makes a MUST gate before every edit.
The justification also cited checkCommand as precedent, but checkCommand passes
STRINGS too — it was the second command already hand-rolling around this gap,
while output()'s docstring called itself "the one place that keeps scripted
callers honest". output() now takes an optional renderer and fails on error OR
partial; two hand-rolled sites go away and three tools are covered instead of
one. truncated stays exit 0 (only the listing is capped) and checkCommand's
cycleCount policy stays put.

Efficiency, all re-measured on the 25k-node index:
- The process lookup was chunked with LBUG_QUERY_BATCH_SIZE, calibrated for the
  opposite query shape — that constant is for a whole-node-table scan where more
  items amortise the scan, while this is an `id IN $ids` probe where round trips
  dominate. 20k ids: 617ms at 100, 261ms at 1000. New LBUG_ID_PROBE_BATCH_SIZE,
  documented against its sibling so they cannot be re-merged. This also settles
  the older "chunking this query is a regression" measurement — that was chunk=100.
- The sort comparator re-coerced fields ChangedSymbolRow already types, O(n log n)
  redundant conversions (+31-38%). Row shape probed directly: alias-keyed, no
  positional keys, numeric columns are JS numbers.
- exactlyMatchedPaths built two throwaway arrays; one loop instead (40k rows
  11.4ms -> 4.5ms).
- The integration fixture seeded 710 step edges one round trip at a time; one
  UNWIND instead. File wall time 6.91s -> 3.63s. Fixture size unchanged — its
  docstring records the threshold below which the bug stops reproducing, and the
  mutation check still fails 3/3 when ORDER BY step is reverted.

Reuse and simplification:
- CALL_EDGE_LIMIT existed in four places; its own docstring predicted the drift
  it then caused. prompts.ts owns it now — it is a zero-import leaf so the
  direction cannot cycle, and had graph-queries.ts owned it the four suites that
  vi.mock that module would have left slice(0, undefined), silently returning
  every edge in exactly the tests meant to police the cap.
- Six dead positional row fallbacks survived the rewrite in the loop this branch
  re-indented, in the same PR that deleted the identical ABI from graph-queries.ts.
- Two test files independently modelled the same labels() scalar-string quirk.
  Deleted the wiki one — the file's own new header says semantics belong in the
  real-engine test — and kept projectTypeColumn, the only instrument that can see
  the bug for the detect_changes query.
- makeRepo onto the shared git bootstrap (the eleventh copy of the sequence the
  helper was extracted to own), the duplicate diff-args unwrapper merged into
  test/helpers, hand-rolled comparators onto compareCodeUnits, real-timer sleeps
  replaced by wave-released promises with a strengthened per-wave assertion.
- Re-exports trimmed to what is actually imported, a cross-reference this branch
  invalidated by moving mapConcurrent, and a "~20% faster" claim that does not
  survive at real index sizes (1-9%; the 10x memory win does).

Also adds the drift guard the new doc text lacked: fragment coverage for the
partial/truncated paragraph in every skill copy and in the managed AGENTS.md /
CLAUDE.md block. Falsifiability checked — none of those fragments exist at the
merge base.

Not done here, deliberately: 27 live labels(x)[0] projections remain across
impact/context/query/trace and MCP resources, with four load-bearing workarounds
that have begun depending on each other and one that fabricates rather than
degrades. That is a semantic change to five agent-facing tools and wants its own
PR, scoped to delete the workarounds too.

* fix(cli): restore the detect-changes subcommand in the regression example (#2915)

Caught by the gitnexus-check bot on the PR. The regression-review fallback in
the injected mandate rendered as `--scope compare --base-ref "main" --repo .`
with no command, so anyone copying it invokes the runner with an option as its
first argument.

Self-inflicted, and by exactly the mechanism flagged when it landed: the block
is under a test-enforced size cap (#856) that had 30 characters of headroom, so
adding the partial/truncated clause required paying for it, and the 38-character
"repeat" that was dropped turned out to be the subcommand rather than a repeat.

Paid for the restoration out of the clause instead — both parentheticals are
gone, since `partial` and `truncated` are already defined in the tool
description this text points at. Block is back under the cap at 3548/3552.

Notably the cap has now been raised four times (2700 -> 2900 -> 2950, then
0.55 -> 0.65) each with the argument that the new line is load-bearing, and it
has now also caused a user-facing defect. It is not functioning as a budget.
Left at 0.65 here rather than making it five: moving the threshold to fit one's
own text is how it got here. Worth restructuring separately.

The fragment guard added a commit ago caught the rewording immediately, which
is what it is for; its fragments now pin the two policy claims rather than the
prose around them, since that prose is what gets re-trimmed under the cap.

Also verified and NOT changed: the bot's other error, that detect_changes
compares 1-based hunks against 0-based graph lines. `bounds` is built from
`coalesceHunksByPath`, which applies `toZeroBasedLine` to both ends at the
grouping boundary, and both a mocked and a real-engine test pin an edit landing
on a symbol's last line. The bot read `parseDiffHunks` in isolation.

* fix(core): reject a fractional chunk size, and stop the truncation note overclaiming (#2915)

All five from the gitnexus-check bot's pass on the previous push; two were
introduced by the cleanup round that preceded it.

`chunk` guarded with `Number.isFinite`, which admits a fractional size — and
that one does not fail, it DUPLICATES. `slice` truncates its indices while `i`
does not, so size 1.5 yields slice(0, 1.5) = items 0-1 then slice(1.5, 3) =
items 1-2, putting item 1 in two batches; a caller batching a query would send
it twice. A size is a count, so `Number.isInteger`. Unreachable today (every
caller passes a constant) but the guard existed precisely for the unreachable
case, and the NaN half of it was already there.

`mapConcurrent`'s per-item degradation contract had a hole: `onError` is
caller-supplied and was invoked outside a try, so a throwing reporter rejected
`settle`, rejected the whole `Promise.all` wave, and discarded the neighbouring
successes the function exists to preserve. Reporting a failure must not become
one.

The CLI truncation note asserted "the counts and risk level still cover all of
them", which is true only when `truncated` fires alone — with `partial` the
counts are summed from the batches that succeeded. It now varies: a distinct
string when both flags are set, saying the counts are a lower bound. This is the
same claim already corrected in the tool description; the CLI text still had the
old one.

The di-extractors contract docstring claimed the barrel re-exports everything
from it. That stopped being true when the re-export was trimmed to what is
actually imported, one commit earlier.

The real-engine wiki test claimed to prepare "every exported query" and omitted
`getInterModuleEdgesForOverview`, which `generateOverview` calls. Added — it
aggregates in JS over `getInterFileCallEdges` rather than issuing its own
Cypher, so the note says why it is in a prepare test.

Verified and NOT changed: the bot's other error, that detect_changes compares
1-based hunks against 0-based graph lines. `bounds` is built from
`coalesceHunksByPath`, which converts both ends at the grouping boundary
(storage/git.ts), and two tests pin an edit landing on a symbol's last line.
The remaining seven findings are changed-symbol heads-ups with no signature
change; their callers' suites are green.

* fix(mcp): make the IMPACT_MAX_CHUNKS fallback actually fire (#2915)

The validation added earlier this branch used `Number.parseInt`, which takes the
numeric PREFIX: '1.5' parses to 1, satisfies `Number.isInteger`, and silently
caps enrichment after a single 100-item batch — the opposite of the fallback the
comment beside it promised. `Number` instead, so a fractional value is rejected
and falls back to 10.

The emptiness check is load-bearing rather than defensive: `Number('')` is 0 and
0 is a legitimate value here (enrich nothing), so an UNSET variable would
otherwise mean "enrich nothing" rather than "use the default".

Behaviour table, old vs new: '1.5' 1 -> 10 (the bug), and undefined/''/'  '/
'10junk'/'-2'/'all' -> 10, '0' -> 0, '3' -> 3, ' 5 ' -> 5 all unchanged. So the
only case that moves is the reported one.

fix(scope-resolution): resolve a package whose directory name repeats higher in the path (#2881) (#2929)
* fix(kotlin): resolve a root-level package whose name repeats higher in the path

`getKotlinFileIndex` built its `dirChildren` buckets under two guards
inherited from the pre-index per-import scan rather than from anything
Kotlin requires: a `startsWith` test that skipped the bucket when the
path began with the package name, and an `indexOf` equality that
demanded the parent be the FIRST occurrence of `/<name>/` in the path.

`s` is taken as `dir.slice(i + 1)` at each `/`, so `dir` ends with `/s`
by construction and the file always IS a direct child of a directory
named `s`. The guards therefore dropped legitimate buckets:

  data/src/main/kotlin/com/example/data/Repo.kt   (leading, startsWith)
  top/data/mid/data/Repo.kt                       (mid-path, indexOf)

`import data.helper` resolved to null against both. Only the fan-out
tier was affected — `data.Repo` answers from `suffixByStem`, which
carries no such guard — which is why the shape looked narrow enough for
#2872 to preserve rather than change inside a performance PR.

Both guards are removed. The rule stays "the parent directory is named
`s`" — a name that appears in the path without being the parent
(`top/data/mid/Repo.kt` for `data.something`) is still not a child, and
a new case pins that.

Widening is filtered downstream for the fan-out tier, which hands the
finalize pass a candidate list (#1759), but NOT for the tier-1 fallback,
which commits to `children[0]` unfiltered — and that is where most of
the change lands: 149 of the 235 moved corpus records are a different
first child against 32 wider arrays. Both are deliberate. A narrower
bucket for the first-child tier alone would keep its answers identical
and would also leave `import data.*` — a wildcard, which strips to
`data` and lands on exactly that tier — resolving to null on the very
shape this fixes.

Both Kotlin benches are re-baselined deliberately, with the drift
measured rather than accepted:

  - bench/kotlin-import-target: 235 of 19968 distinct records moved.
    54 null -> resolved (the fix, and exactly the +54 in non_null),
    181 answers that changed within a now-larger bucket. Zero buckets
    lost a member, zero results were dropped, and every reselected
    answer's parent directory is the queried package segment. The
    corpus is untouched, so `cases` is unchanged and the fingerprint
    covers the same surface as the value it replaces.

  - bench/import-target: the collide arm needed a corpus edit beside
    the new numbers. Its `d % 7` slice imported `com.example.vendor{d}`,
    a package that exists nowhere, purely to mirror the unique arm's
    nested-slice MISS; with that slice now resolving, leaving it would
    have left collide at 1100 against small's 1153 and broken the
    same-workload invariant the arm is built on. That assertion is what
    caught it.

The gate controls were re-run against the new baseline, including one
the fix makes newly plausible: a HALF fix that drops only `startsWith`
and keeps the `indexOf` check still fails the fingerprint, so a partial
fix cannot land quietly.

Two gates moved with the code rather than being left behind:

  - kotlin `heap_reading_bytes` and `heap_ceiling_bytes` are re-recorded
    together as `_heap_reading_note` requires (48073096 -> 48200224,
    +0.264%, ceiling still 1.5x). The note says why that is small: the
    heap corpus is built with HEAP_PAD 8, so no path can begin with a
    suffix of its own directory and the leading-segment half of the old
    rule is invisible to that arm.

  - `depth_budget` 2.4 -> 2.2. Deleting two string comparisons per
    directory component is per-depth work, so the depth band fell from
    1.44-1.51 to 1.27-1.40; left at 2.4 the gate's headroom would have
    drifted from ~1.6x to ~1.8x without anyone deciding to loosen it.

`package-dir-index.ts` documents the same first-occurrence rule as
universal, and it is not any more: Go, Java and C# still carry it and
still have the shape. Fixing them means re-baselining three languages
and editing the verbatim pre-change scans that
import-target-index-parity.test.ts keeps as the specification, so it is
a separate change — the comment now says so instead of describing a rule
one of its readers no longer follows.

Fixes #2881.

* fix(scope-resolution): drop the first-occurrence directory rule for Java, Go and C# too

#2881 was reported against Kotlin, but the rule it removed was never
Kotlin's. It is what the pre-index per-import scan happened to compute —
`indexOf` for the package directory, then "nothing after the match holds
a slash" — and every resolver built to reproduce that scan inherited it.
Three still had it, and all three reproduced the reported defect:

  java   data/src/main/java/com/example/data/Repo.java  `import data.*`  -> null
  java   top/data/mid/data/Repo.java                    `import data.*`  -> null
  csharp Models/src/App/Models/User.cs                  `using Models;`  -> null
  csharp a/Models/b/Models/User.cs                      `using Models;`  -> null
  go     a/internal/auth/b/internal/auth/svc.go   import "internal/auth" -> null

Controls (`top/data/Repo.java`, `a/b/internal/auth/svc.go`) resolve, so
these are the rule firing rather than an unrelated miss.

Four sites, all reduced to "the file's parent directory ends with the
queried path":

  - `package-dir-index.ts` `matchingDirs` (Go, Java, C# without csproj):
    the `indexOf` equality becomes `endsWith`, which also subsumes the
    length guard it needed — a shorter haystack is false instead of
    comparing -1 to -1.
  - `csharp.ts` `matchingDirPositions` (csproj step 3): same, and still
    deliberately UNANCHORED, so `src/SubModels` keeps answering `Models`.
  - `csharp.ts` csproj step 2: `indexOf` -> `lastIndexOf`, EXCEPT for an
    empty `dirPrefix`, which must keep `indexOf`. Its needle is a bare
    '/', and step 3 answers that query from `singleSegmentDirs` ("exactly
    one directory deep"), which only the first occurrence expresses; with
    `lastIndexOf` there, step 2 accepts every `.cs` in any directory and
    diverges from step 3. The csproj parity test catches it.
  - `go.ts` `resolveGoPackage`: `indexOf` -> `lastIndexOf`. No production
    caller, but the parity harness copies it verbatim as its spec.

The two C# csproj sites must move together. Fixing only step 3 makes
`Lib.Models` return step 3's superset instead of step 2's segment-aligned
answer.

Risk is not symmetric across the three. Go's consumer is a fan-out list
and the finalize pass materializes one IMPORTS edge per element, so
widening only ADDS edges. Java and C#-without-csproj commit to a single
file through `firstFileDirectlyInPkgDir` with no downstream filter, so a
widened bucket can also change which file an already-resolving import
binds to — java's collide fingerprints moved while its resolved count
did not, which is exactly that. C#'s leg is additionally gated by
`csharpSuffixFallbackAllowed` (#1881) before resolution runs.

Gates:

  - Twenty fingerprints re-baselined across go, csharp and java (five
    arms plus the top-level alias each). resolved 979 -> 1153 small,
    4064 -> 4681 large for go and csharp; 1100 -> 1153 / 4456 -> 4681 for
    java. No `distinct_outcomes` moved.

  - csharp and java hit the same collide-arm trap Kotlin did: both sent
    their `d % 7` slice to a namespace that exists nowhere purely to
    mirror the unique arm's nested-slice MISS, so once that became a hit
    the arms resolved fewer imports than `small` and the same-workload
    assertion failed. Both now use their arm's ordinary spelling.

  - GO WAS NOT GATED AT ALL and the corpus had to change to make it so.
    Its nested slice repeated only the last segment (`src/pkg{d}/internal/
    pkg{d}`) while a Go query addresses the whole package path, so the
    directory never ended with the query and the rule was never reached —
    every go arm sat unchanged through the resolver fix. `uniqueDir` and
    `collideDir` now repeat the shape at the granularity Go queries.
    `languages.go.heap.path_segments` 13 -> 14 follows from that.

  - `csharp_csproj`'s heap reading moved -0.79% (stable across runs) and
    is re-recorded with its ceiling: the step-2 filter decides which lazy
    `getFilesInDir` maps the probe forces. Everything else stayed within
    +/-0.03%, which is this box's jitter — `_heap_reading_note`'s claim
    that the readings reproduce to the byte across processes did not hold
    here, and the note now says so.

The three parity harnesses keep VERBATIM copies of the pre-change scans
as their specification, so each copy was updated with the resolver and
the cases that pinned the rule now pin its removal. Two of them left the
`mustBeNull` set in the shared harness — they resolve now, which holds
them to the stronger "pin a winner" bar the rest of that arm uses.

* perf(kotlin): intern dirChildren keys per directory and compact the buckets

Two optimizations to `getKotlinFileIndex`, both output-identical, kept
because they were measured and a third was dropped because it was not.

1. PER-DIRECTORY KEY MEMO. The component walk over `dir` cut one `slice`
   per component per FILE, and every slice after the first file of a
   directory is a freshly allocated string that hashes to a key the map
   already holds and is then dropped. The key list is a pure function of
   `dir`, so it is interned once per DIRECTORY. Measured -18.4% to -21.7%
   of the build at 32 000 files; zero retained cost, the memo dies with
   the frame.

2. BUCKET COMPACTION at the freeze loop. `addChild` mints `[raw]` and
   pushes, and V8 grows a backing store by `old + old/2 + 16`, so the
   SECOND child takes a 1-slot store to 17 and every bucket then retains
   its overshoot. 61 144 buckets at 32 000 files, 52.9% of their slots
   empty, 88 B each. `slice()` on freeze: -5 397 768 B, -11.20%, and the
   predicted 5 382 507 B lands within 0.03% of it. Same fix and the same
   accounting as the python `byBasename` note this repo already carries.

   `length === 1` is skipped deliberately. A bucket that never grew is
   already exact, so slicing it allocates a second array to save nothing
   — on a corpus of single-file packages the unguarded form costs 31% of
   the build for zero bytes.

DROPPED: merging the `dirChildren` walk into the `suffixByStem` walk.
It measures -0.10% at 32k, +0.23% at 100k and +0.40% at one file per
directory, all inside a base-vs-identical-copy noise floor of -2.3% to
+3.1%, and it does not compose usefully with the memo — the second scan
it deletes is exactly the scan the memo makes rare. Only its provably
free half is kept: `stem.lastIndexOf('/')` in place of `norm.lastIndexOf`,
one backwards scan instead of two, exact because an extension carries no
'/'.

Neither optimization is visible to the correctness fingerprint, which is
the point and also the risk: it observes the index only through the four
resolver tiers, so a key-order move no corpus query reaches would survive
it. Correctness therefore rests on a structural comparison of all three
maps — key insertion order, values, bucket contents in order, frozen-ness
— over 1234 corpora in both iteration orders, 14 808 comparisons, zero
failures. The fingerprint, `cases` and `non_null` are unchanged and MUST
NOT be re-baselined by this commit.

Gates that did move, both because a reading and its budget move with the
code rather than when CI goes red:

  - `heap_reading_bytes.kotlin` 48 200 224 -> 42 802 456 with its ceiling
    at 1.5x. A memory WIN passes every arm, so nothing forced this.
  - `depth_budget` 2.2 -> 2.0. The memo turns a per-file component walk
    into a per-directory one, which is precisely the per-depth work this
    arm exists to see: the band went 1.27-1.40 -> 1.20-1.26, and 2.2 held
    over it would have drifted from ~1.6x headroom to ~1.9x.

The gate controls were re-run against the optimized builder, including
one this change makes newly plausible: keying the memo on the directory's
LAST SEGMENT instead of its full path drifts the fingerprint
(36a4e9dad313, non_null 13310 -> 13305). That is the memo's whole
safety argument stated as a test — its key decides which key set a
directory contributes — and it is the one way this optimization could
move an answer. The bucket-cap control was re-run too, since compaction
now rewrites the same buckets.

Also recorded, from measuring a reuse this repo had been invited to make:
replacing `dirChildren` with the shared `package-dir-index` is
output-identical (0 divergences over 107 948 answers) and passes every
arm of the kotlin bench at 1.37x-1.50x — while costing 409x per fan-out
and 8114x on `import data.*` at 200 matching directories on a corpus this
bench does not carry. `_blind_spot` in the kotlin baselines now says so,
with the memory the trade would have bought (26.2%, 12.18 MiB) and the
corpus arm that would have to exist first.

* fix(scope-resolution): close the gaps a four-lens review found in the #2881 change

Correctness review found no defect in the shipped resolvers — the `endsWith`
rewrites, the C# empty-prefix guard, the memo's purity, the `stem` vs `norm`
derivation, the Map re-`set` during iteration and Go's `substring` arithmetic
were each attacked with running code and each held. Everything below is a gap
in what the change ASSERTS, measures or claims.

UNGATED BEHAVIOUR, now covered:

  - `import-resolvers/go.ts` had no test at all. Its rule changed, the shared
    bench drives the indexed leg rather than this one, and a revert was caught
    by nothing. `go-package-resolve.test.ts` pins the membership rule and, more
    usefully, pins that Go's two independent legs agree on it — they disagreed
    before #2881 and a divergence here means the LanguageProvider hook and the
    ScopeResolver hook hold different views of a package.
  - The memo and the compaction are output-identical, so no fingerprint sees
    them and reverting either leaves both benches green. `kotlin-index-internals
    .test.ts` asserts them directly: the memo hit path against the miss path,
    two directories sharing a component-suffix keeping separate buckets (the one
    way a coarser memo key could move an answer), and that the bucket handed out
    is the cached, frozen, compacted array on both the sliced and the skipped
    path. The comment claiming this was "asserted structurally" previously
    pointed at nothing in the repo.

GATES:

  - Six ratio budgets in `bench/import-target` were slack: the measurements they
    bound got faster and the numbers were left alone. kotlin depth 3.4 -> 2.8,
    go 1.6 -> 1.4, csharp 2.2 -> 2.0, java 2.2 -> 2.1, kotlin collide_scaling
    1.8 -> 1.65, go 5.5 -> 5.1, each holding the headroom the old value
    expressed. The absolute ms ceilings are deliberately untouched: they carry
    runner-contention headroom, and a ratio is runner-speed-invariant where a
    millisecond is not. This is the failure the branch already fixed one
    directory over and missed here.
  - The `csharp_csproj` heap re-baseline is REVERTED. Base and branch both
    measure ~73.10e6 three runs each; the recorded 73703384 was simply not
    reproducible, and re-recording it would have dropped that language's derived
    floor 0.8% for no reason belonging to this change.
  - kotlin's collide arm was blind to the rule it was re-baselined for — a full
    revert of the Kotlin guards left both its fingerprints unmoved, because
    `com/example/models` is not a suffix of `…/models/inner/models`. Deepened to
    repeat the whole queried path; those two fingerprints are the only ones that
    moved for it. The same deepening on the java and kotlin UNIQUE arms was
    measured and REVERTED: ten more fingerprints, java's heap reading up 43%,
    and no coverage gained, because progressive stripping lands those queries on
    the same file either way.

SIMPLIFICATION:

  - `go.ts` now states the predicate as ends-with like its three siblings,
    instead of keeping the `indexOf` shape with `lastIndexOf` swapped in.
  - C# csproj step 2's direct-child filter is dead for a non-empty prefix —
    `getFilesInDir`'s keys ARE segment-aligned directory suffixes, so it cannot
    reject, and measurement agrees over 12 008 pairs. Only the empty-prefix case
    does work, and only that case remains.
  - `addChild` had one call site left; inlined. The memo's double read of its
    own lookup is gone. The V8 byte accounting duplicated verbatim between the
    resolver comment and the baselines note now lives only in the note.
  - Four copies of the same ternary in the csproj parity harness collapse onto
    one hoisted `dirTrail`; two locals in the java harness were named for the
    branch that was deleted.

CLAIMS THAT WERE WRONG:

  - `package-dir-index.ts` said "the four resolvers agree again". It is six, and
    the sixth is the evidence: `import-resolvers/jvm.ts` has answered the same
    question with `lastIndexOf` since #488, so before #2881 Java's and Kotlin's
    LanguageProvider hook and their ScopeResolver hook disagreed about which
    files a package holds.
  - The `uniqueDir` docblock claimed the last segment IS the query granularity
    for csharp/java/kotlin. They query the whole dotted path first and reach the
    tail only through stripping — which is why the partial-revert control fires
    on the go arm alone, now stated instead of implied.
  - Three parity harnesses described themselves as verbatim copies of the
    pre-change implementations; they were edited by this branch, so they are
    re-derivations of the current spec, a weaker claim their headers now make.
  - The shared harness header still listed the removed rule as current, the
    `DIRS` docblock still justified shapes by a divergence that no longer
    exists, and `measure.mjs`'s tier-two docblock plus `_heap_bound_note` still
    counted nine bounded languages when `HEAP_BOUNDED` derives to three — this
    branch had dutifully updated a kotlin bound in a list no gate reads.
  - `_blind_spot` told the next reader to build a repeated-leaf arm that already
    exists in the sibling bench, with a budget that already fails the swap.

Both baselines are also re-serialized to preserve each note's original escaping,
undoing ~20 KB of no-op churn an earlier revision introduced by round-tripping
the JSON.

* perf(scope-resolution): drop the string each membership test built per candidate

The three `endsWith` membership tests each minted a decorated copy of the
directory once per candidate, per import. The decoration cancels:

  ('/' + D + '/').endsWith('/' + P + '/')  <=>  D === P || D.endsWith('/' + P)
  (D + '/').endsWith(P + '/')              <=>  D.endsWith(P)

Verified exhaustively rather than argued — every pair of strings up to length 5
over `{a, b, /}` including the empty string, 132496 pairs, 0 divergences, with
the match count reported beside it because two predicates that agree on `false`
everywhere also show 0 divergences. `matchingDirs` 32.58 -> 8.22 ns/candidate
(3.96x), `matchingDirPositions` 64.9 -> 18.4 ns. C#'s deliberate unanchoredness
survives verbatim: `src/SubModels` still answers `Models`.

`resolveGoPackage` was the opposite of a win — the rewrite in this branch left
the `'/' + path` cons the old `includes` guard used to short-circuit, and the
first `endsWith` forces V8 to flatten it once per file. Working on the raw path
with an explicit start index is 4.8x faster than that and 1.78x faster than the
code before this branch. It also now reuses `resolveGoPackageDir` instead of
re-deriving six of its lines.

Three claims these files make are corrected while they are open:

- `package-dir-index.ts` argued the rule was accidental because a sixth
  implementation never had it, "wired as `importResolver` by
  `languages/{java,kotlin}.ts`" and therefore live. It is wired and not read:
  `provider.importResolver` is consumed only at `import-target-adapter.ts:74-75`,
  and that module's exports have no importer outside their own unit test, while
  its docblock claims it is threaded through `finalizeScopeModel`. The argument
  survives on the pre-index-scan derivation; `jvm.ts` is evidence about how the
  predicate was written, not about live behaviour. Whether those resolvers
  should be deleted or wired is left as an open question.
- `csharp.ts` derived the empty `dirPrefix` case from "any path whose first
  slash is its last", which is wrong in both directions: `src/X.cs` satisfies it
  and emits no empty key, `a//X.cs` violates it and does. The conclusion stands
  and the filter stays — it is what rejects `a//X.cs`.
- Step 2 returns on its first push, so widening it also suppresses step 3's
  unanchored leg. The narrower answer is the more precise one, but it was an
  unstated output change.

`SuffixIndex.getFilesInDir` now states the segment-alignment its callers rely on,
bounded as a guarantee about what may be RETURNED — php's root-anchored index
answers only the equality arm.

* fix(scope-resolution): say what the widened bucket actually does downstream

The comment justifying the widening claimed a bucket that is too wide is
"filtered downstream" by the finalize pass. It is not, for the edge that
matters. `finalize-algorithm.ts` mints one draft per candidate, each keeping its
own `targetFile`, and the File->File emitter in
`graph-bridge/imports-to-edges.ts` tests only `targetFile === null` and
`targetFile === sourceFile` before adding an `IMPORTS` relationship at
confidence 1.0 — it never reads `linkStatus`. The `localDefs` filter from #1759
constrains `targetDefId` and the `BindingRef`; every extra bucket member is an
unconditional file-level edge regardless. Measured on an Android-shaped layout,
one `import data.load` goes from 5 to 6 edges, all six unresolved.

No filtering is added here. Whether an unresolved candidate should produce that
edge at all is a design question about the graph bridge, not about this bucket.

The published drift census — 149 first-child reselections, 32 wider arrays, 54
null -> resolved — has no bucket for a fourth class this change introduces.
Tier 3 precedes tier 4, so a bucket the guards used to leave empty returned null
and let the progressive strip run; a populated bucket stops tier 4 entirely,
turning a bound answer into a candidate list that need not carry the symbol.
Re-running the census with a shape classifier finds that class ZERO times over
the corpus, and the zero is the finding: the shape reproduces by hand, and this
bench's own generator at 4000 repositories hits it 4-12 times per seed. The
fingerprint cannot gate what the corpus cannot express — the same blindness the
go arm carried until #2881 widened it.

Two further claims are brought back in line with what shipped. The memo's
docblock said `kotlin-index-internals.test.ts` asserts the key set, key
insertion order and bucket order "over the built maps"; that file says it works
through the resolver's observable surface and omits key order deliberately. The
mutation matrix bounds it honestly: a mis-keyed memo is caught, a deleted one is
not, and the compaction's only instrument is the bench heap ceiling.
`findKotlinDirectoryChild` no longer claims to return "the same file the scan
used to return" — that is precisely what moved.

Structural, no behaviour: `let keys` sits with its consumer instead of 33 lines
above it, the archaeology moves to the docblock, `tight` -> `compacted`,
`dirEnd` -> `lastSlash` (the name three sibling builders use), and the one-use
`MutableDirChildren` alias goes with the `addChild` it existed for.

`finalize-algorithm.ts` annotates `targetFiles` as `readonly string[]` so
`Array.isArray`'s `any[]` predicate can no longer widen a frozen cached bucket
into something `.sort()` compiles against. The runtime freeze stays; it is the
backstop for every other call site.

* test(scope-resolution): gate the edges #2881 moved but nothing watched

Every widened-shape test in the branch used a one-file corpus, so not one of the
149 first-child reselections was pinned — the tier that commits to `children[0]`
unfiltered had no test that could see which file it commits to. Kotlin and Java
now pin that choice absolutely, in both insertion orders, for the member path
(tier 3, both members) and the wildcard path (tier 1, one file) separately,
saying plainly that both candidates are valid members and the only tie-break is
file-set iteration order.

The tier-3-preempts-tier-4 class gets its first gate, with a control that makes
it a transition rather than a fact. The bench corpus holds zero instances, so
this case is the only thing standing between that behaviour and a silent
revert.

C# gains three absolute arms, because its differential harness cannot see any of
them — the legacy copy was edited in lockstep with production, which the file's
own header admits. One pins the empty-`dirPrefix` filter the branch calls
load-bearing and which nothing defended: deleting the guard leaves the whole
suite green but changes the answer, so the arm was verified to fail with the
guard removed and pass with it restored. Java gains the negative control Kotlin
already had.

`kotlin-index-internals.test.ts` stops implying coverage it does not have. The
mutation matrix is recorded in its header: deleting the memo passes every arm
(it is output-identical by construction), deleting the compaction's `slice()`
passes every arm (a JS array's capacity has no reflective surface), while
mis-keying the memo fails three and compacting-but-never-storing fails two. Four
arms were added that do fail under those mutations. V8's growth steps were
re-measured — 1, 19, 46, 86 with growth at lengths 2, 20, 47, 87 — so the old
1/17/41 model, which under-counted the slack at 40 files by 6x, is gone.

`go-package-resolve.test.ts` drops four `as never` casts that were hiding
nothing (`GoModuleConfig` is structurally satisfied), and pins vendor/, testdata/
and nested-go.mod directories, which merge into the importing package — a
pre-existing unmodelled gap, verified present before #2881 and documented as
such rather than blamed on it.

* test(bench): gate the bucket compaction, and publish the whole drift taxonomy

The compaction shipped with no gate anywhere. Deleting `bucket.slice()` while
keeping the freeze moves no fingerprint, no count and no test — only retained
heap, 42805256 -> 48184784 B (+12.57%), byte-identical across three runs. Note
the direction: compaction reclaims, so losing it makes the reading GROW, which
no floor can see. `heap_ceiling_bytes.kotlin` tightens 64203684 -> 46000000
(1.5x -> 1.0747x of the reading), leaving the regression 4.8% clear above the
ceiling and the reading 7.5% below it. The band is derived from first principles
in `_heap_compaction_gate` (~61000 buckets x 11 spare slots at Node 22's 1->19
step) so it can be re-checked rather than trusted, and the note carries the
triage rule: heapUsed accounting drift moves every arm, so kotlin alone over its
ceiling is a lost compaction.

`_gate_controls` claimed the two optimizations rest on a structural comparison
over 1234 corpora in both iteration orders. No such probe exists in the tree. It
now names the test that does exist and lists what it actually pins, and says
key insertion order is unasserted by design.

`_provenance` gains the full shape classification behind the 235 moved records:
149 string -> string, 38 null -> string, 16 null -> array, 32 array grew, and
zero of every other transition — including `string -> array`, the
resolved-becomes-unresolved class the old taxonomy had no bucket for. The
harness was validated byte-exactly first: driven over this corpus the base
resolver reproduces ebf1790bf1 / 13256 and head reproduces d91110bee3 / 13310.

`measure.mjs` loses a paragraph asserting the C# unique slice repeats the whole
queried path, directly above the paragraph explaining it is leaf-only
deliberately and the code that makes it so. Acting on the deleted half resolves
the csproj arm to zero. While measuring: the csharp collide arm is NOT blind —
its fingerprint already moves across #2881 — but both csharp_csproj arms are,
because `getFilesInDir` keys on segment-aligned suffixes and neither nested slice
is one. Closing that needs a corpus redesign and four re-baselines; recorded, not
attempted.

One number changes in either baselines file, and it tightens.

fix(storage): strip credentials from remote URLs before they are persisted (#2914) (#2928)
`git config --get remote.origin.url` returns whatever the checkout was
configured with, and the HTTPS token form
`https://x-access-token:<token>@host/owner/repo` is how CI checkouts and
credential helpers routinely authenticate. `getRemoteUrl` kept that value
verbatim, so it reached `~/.gitnexus/registry.json` and the per-repo meta,
and MCP `list_repos` echoed it back — repository discovery doubled as
credential disclosure.

Three edges, one helper:

- `stripUrlCredentials` drops `user[:password]@` userinfo from http(s) URLs.
  `ssh://git@host/…` and SCP-like `git@host:owner/repo` are left alone: that
  is an SSH user name, not a secret, and rewriting it would repoint the
  sibling-clone fingerprint (#2054) for every registered repo.
- `getRemoteUrl` strips at capture, before the existing host lower-casing —
  that regex treats the whole `user:pass@host` span as the host, so it was
  also mangling the credential's case on the way to disk.
- The registry sanitizes on read AND write, so a `registry.json` (or a
  per-repo meta copied forward by a re-register) written by an older version
  is neither emitted nor rewritten with the credential still in it.

Also strips both URLs from the clone/remote mismatch error in
`assertRemoteMatchesRequestedUrl`, which is echoed to API callers and the
server log.

Sanitized values compare equal to a freshly captured remote on both sides,
so sibling matching, drift checks and `--name` inference are unchanged.

fix(cli): stop churning the committed agent guides, and nudge --index-only (#2907) (#2927)
AGENTS.md and CLAUDE.md are the agent guides teams commit, and the injected
block carried live symbol/relationship/flow counts. Those counts move with any
code change, so every reindex rewrote a tracked file and produced a spurious
diff that had to be restored by hand before committing real work.

The write is now skipped when the volatile counts are the only delta. Counts are
substituted with placeholders — not deleted — before the comparison, so
--no-stats REMOVING the parenthetical is still a material change that writes
through; only a numbers-only difference is suppressed. Both the verbose path and
the gitnexus:keep path go through the same rule, and a project rename, a template
change, or a base_ref change still rewrites as before. Live counts remain
available from `gitnexus status` and `gitnexus://repo/{name}/context`.

Two smaller churn sources go with it:

- The file was CREATED without a trailing newline while every update path writes
  `.trim() + '\n'`, so the analyze right after committing a freshly created
  AGENTS.md dirtied it purely to append that newline.
- `--no-stats` left the per-cluster `(N symbols)` counts in the skills table,
  which are exactly as volatile as the header parenthetical the flag removes.

The stale-index hook recommended plain `gitnexus analyze` — the variant that
rewrites those tracked docs — so an agent following the nudge verbatim reindexed
with the most invasive flags. `formatAnalyzeCommand` takes `indexOnly` and the
three hook call sites (Claude, plugin copy, Antigravity) pass it; the injected
"Index stale?" line and the MCP context resource's `re_index` hint name the same
`--index-only` form. Full `analyze` stays the documented way to refresh the docs
and skills.

Both resolve-analyze-cmd.cjs copies stay byte-identical.
