feat: add Zig language support (#1432)
* feat: add Zig language support
Adds a Zig LanguageProvider grounded in @tree-sitter-grammars/tree-sitter-zig 1.1.2.
The grammar's published peerOptional `tree-sitter@^0.22.1` is suppressed via an
npm `overrides` entry that aliases the peer to the bundled `tree-sitter@0.21.x`;
load-time smoke testing confirmed ABI compatibility.
v1 capabilities:
- .zig file detection + Prism syntax mapping
- Top-level + nested function_declaration as Function/Method
- struct/enum/union (anonymous in the grammar — owner name resolved from the
enclosing variable_declaration in class/field/method extractors)
- container_field as struct/union fields and enum variants
- top-level const/var as Variable nodes
- free + member call_expression as @call edges
- @import("./foo.zig") local-file resolution; std and external packages
return empty (no ghost edges)
- pub keyword detection for export checking
- no heritage hooks (Zig has no inheritance; queries never emit @heritage.*)
Generic extractor changes (backward-compatible):
- field-extractors/generic.ts and method-extractors/generic.ts: empty
`bodyNodeTypes` falls back to the type declaration node itself as its own
body container — needed because Zig's struct_declaration directly contains
its container_field children. (The `extractOwnerName` hook this commit
originally introduced now exists upstream; Zig just configures it.)
Out of scope (deferred):
- usingnamespace, build.zig.zon package graph, comptime/anytype
- scope-resolution hooks (emitScopeCaptures, interpretImport, …): Zig is
classified `experimental` and uses the generic fallback resolution path
- cross-package imports (std, deps)
Tests:
- new fixture test/fixtures/sample-code/simple.zig
- Zig describe block in tree-sitter-languages integration test
- simple.zig added to parsing.test.ts fixture-existence list
- Zig added to ingestion-utils detection unit test
- Zig smoke case in parser-loader-abi.test.ts
- Zig grammar registered in the grammar-literal validation gate
* feat(zig): integrate build.zig.zon resolution + Union label from PR 1096
Ports the additive pieces of grgisme's standalone Zig provider PR
(https://github.com/abhigyanpatwari/GitNexus/pull/1096) onto the rebased
provider:
- build.zig.zon `.path` dependency resolution for bare-name
@import("pkg") (parseZigBuildZon / loadZigBuildZon in
language-config.ts, resolveZigImportInternal in import-resolvers/zig.ts,
wired through ImportConfigs.zigBuildZon). `.url` deps and
repo-escaping paths return null cleanly. 13 unit tests.
- `union(enum)` containers now produce `Union` nodes (not Struct):
'Union' added to ClassLikeNodeLabel + CLASS_LIKE_LABELS, the Zig query
tags @definition.union, CONTAINER_TYPE_TO_LABEL maps union_declaration
to 'Union'. The label was already plumbed graph-wide on main.
- /^build$/ entry-point pattern (build.zig).
- zig-basic lang-resolution fixture + resolvers integration test.
Adapted to current main while porting:
- labelOverride relabels container-nested fns Function → Method
(mirrors isKotlinClassMethod); the structure phase no longer derives
Method from the legacy method-extraction path for plain
@definition.function captures.
- IMPORTS/CALLS edges require scope-resolution hooks
(emitScopeCaptures / interpretImport) since the legacy DAG removal;
Zig does not implement them yet, so the integration test documents
that with a skipped import-edge case. The resolver itself is wired
into the resolver factory and becomes live when the hooks land.
Not ported: named-bindings extractor (the legacy namedBindingExtractor
API no longer exists) and the bespoke field extractor (the generic
factory's extractOwnerName / empty-bodyNodeTypes hooks cover Zig).

* feat(zig): scope-resolution hooks — IMPORTS and CALLS edges (Ring 3)
Implements the registry-primary scope-resolution path for Zig, the
prerequisite for cross-file edges since the legacy DAG removal. Adds the
standard per-language stack under languages/zig/:
- query.ts: scope query (containers as Class scopes, blocks, functions),
declarations (container anchors placed on the container node itself so
the def lands in its own Class scope and the name binding auto-hoists
to the parent — populateClassOwnedMembers needs the class-like def
among the class scope's ownedDefs), @import statements (#eq?-gated
builtin), parameter/constructor type bindings, and call/constructor
reference sites. The grammar is required lazily (optionalDependency).
- captures.ts: emitZigScopeCaptures — groups query matches, drops the
plain-variable group for container/import bindings (their dedicated
rules bind the name), and relabels container-nested fns
@declaration.function → @declaration.method (labelOverride parity).
- interpret.ts: namespace-kind imports (const x = @import("…")) and
type bindings — self-parameter convention marks the receiver, Zig
sigils (*, ?, [], error unions, const) stripped from type names while
dotted qualifiers (mod.T) are preserved for Case-3 namespace-prefix
receiver dispatch.
- simple-hooks.ts: parameter bindings stay function-local (Go
rationale), local-over-import merge precedence, bounds-check arity
(always 'unknown' today — no synthesized arity metadata).
- scope-resolver.ts: emit-side wiring; build.zig.zon threads through
loadResolutionConfig into the same resolveZigImportInternal the legacy
resolver config wraps. fieldFallbackOnMethodLookup off (statically
typed). Registered in SCOPE_RESOLVERS.
The resolvers integration test un-skips the import-edge case and gains
CALLS assertions: free call (main → helper) and receiver-bound method
dispatch through a namespace-qualified constructor
(var p = pioneer.Pioneer{…}; p.tick() → main → tick).
* fix(zig): Union is class-like + missing-grammar warning (review pass)
Self-review findings on the Zig branch:
- scope/walkers.ts `isClassLike` and finalize-algorithm's
CALLABLE_OR_TYPE_LIKE did not include 'Union': a `union(enum)`
container's methods got no ownerId from populateClassOwnedMembers, so
method dispatch on union receivers silently dropped. Widened both
sets; the zig-basic fixture gains a Tag method + a CALLS assertion
(main → isEnergy) that fails without the widening (verified by
reverting).
- optional-grammars.ts now lists tree-sitter-zig with an npm `probe`
(it is an optionalDependency, not vendored): users with .zig files
and no prebuild get the standard one-line stderr warning instead of
a silently degraded index.
- Deduplicated the container-method predicate: `isZigContainerMethod`
+ ZIG_CONTAINER_TYPES now live once in languages/zig/captures.ts and
feed both the provider labelOverride and the scope-capture relabel.
- README language matrices: Zig row now claims Type Annotations,
Constructor Inference, and Config (build.zig.zon) — all true since
the scope-resolution hooks landed.
* fix(zig): anchor @declaration.variable to the binding identifier
`(variable_declaration (identifier) @declaration.name)` matched EVERY
identifier child of the node, so `const first = target;` also declared a
phantom local named `target` in the enclosing block. That phantom shadowed
the real function for later references (and starved callable-value-flow
seeds of a target). The `.` anchor pins the pattern to the first named
child — the bound name.
Regression test in resolvers/zig.test.ts pins the capture set.
* feat(zig): callable-value-flow captures + main's per-language conformance gates
Post-rebase catch-up: since this branch forked, main added three "every
registered language must appear here" tests. Each needs a Zig entry:
- callable-value-flow (#2522): Zig now emits `@callable-flow.*` facts via
`synthesizeCallableFlowCaptures` (ZIG_CALLABLE_CAPTURE_OPTIONS in
zig/captures.ts). tree-sitter-zig's `call_expression` carries arguments
as direct children with no wrapper node, which the shared helper could
not decompose, so this adds a language-neutral `extractCallArguments`
hook (mirror of `extractFunctionParameters`; `undefined` = shared path).
Zig joins the provider matrix as 'matrix' with a real assign→copy→
argument→invoke case.
- external-import-conformance (#2953): `@import("std")` beside a decoy
`src/std.zig` resolves to nothing; the decoy stays reachable via the
relative spelling. Zig holds the property (no suffix fallback), so it is
a case, not a KNOWN_GAPS entry.
- import-target-index-reuse contract (#2909): membership-probe-only
fixture (minimumScans: 0, same shape as Rust).
* fix(zig): address gitnexus-check review findings
One commit per the bot's list so each item is easy to check off:
- parser-loader: Zig row gains `userSkippable: true`, so
`GITNEXUS_SKIP_OPTIONAL_GRAMMARS` (=1 or a list naming `zig`) disables it
at analyze time like swift/dart/kotlin — as `optional-grammars.ts` already
documented. Covered in parser-loader-skip-optional.test.ts.
- export-detection: `zigExportChecker` stops at the first declaration it
reaches. A non-`pub` fn inside `pub const T = struct {…}` was reported
exported because the walk continued up to the wrapper.
- import-resolvers/zig: a `.path = "."` dep normalizes to '' and no longer
grows a leading slash (`/src/main.zig` could never match).
- language-config: build.zig.zon parsing strips `//` comments string-aware
(a `//` inside `.url = "https://…"` survives) and matches braces while
skipping string literals, so a commented-out `.path` cannot declare a dep
and a `}` in a comment/string cannot truncate the block.
- method-extractors/configs/zig: the leading `self` receiver is excluded
from `parameters` (Rust parity). Fixing that exposed a worse bug: the
`parameters` node is a plain child of `function_declaration`, not a
`parameters:` field, so `childForFieldName('parameters')` was always null
and every Zig method had no parameters, no receiver and `isStatic: true`.
One `zigParameterList` helper now feeds all three readers.
- variable-extractors/configs/zig: container (`struct`/`enum`/`union`) and
`@import` bindings are skipped via the same predicate the scope captures
use (`isZigContainerOrImportBinding`), instead of the comment merely
claiming they were.
- tree-sitter-languages.test.ts: the "missing grammar" case now forces the
absent-binding path through the loader's runtime opt-out on a fresh module
instead of passing vacuously when the package is installed.
New: test/unit/zig-extractors.test.ts (exports, receiver/parameters,
variable guard); zig-import-resolver.test.ts gains the `.` dep, comment and
brace cases.
The `createFieldExtractor` heads-up needs no change: the added branch is
unreachable for every existing config (none has empty `bodyNodeTypes`).
* fix(zig): address second gitnexus-check review pass
- import-resolvers/zig: `..` above the repository root now returns null
instead of aliasing a same-named root file (`../bar.zig` from `main.zig`
is not `bar.zig`); the stale "extension is stripped and re-added" comment
is corrected to what the code does.
- variable-extractors/configs/zig `extractType`: read the `type:` field only.
The positional fallback returned the INITIALIZER of `const f = target;`
as its type and gave up on compound annotations (`*Foo`, `?[]const u8`).
The comment claiming 1.1.2 has no `type` field on variable_declaration
was wrong (verified by AST dump) — and it is what led the review to
suspect the callable-flow `extractAssignment` callback, which was
already correct for `extern var f: T;`.
- receiver detection: only a FIRST parameter named `self` is the receiver.
`emitZigScopeCaptures` tags first-position parameters
(`@type-binding.first-parameter`), `interpretZigTypeBinding` requires the
tag as well as the name, so `zigReceiverBinding` no longer turns
`fn f(a: u32, self: T)` into an instance method.
- resolvers/zig.test.ts: both suites `describe.skipIf(!zigAvailable)`
(Swift/Dart pattern) — the grammar is an optionalDependency.
- tree-sitter-languages.test.ts: the Zig parsing case gates on
`isLanguageAvailable` instead of a catch-all `return`, so an installed
grammar that fails to load fails the test; comment no longer calls Dart
and Swift npm optionalDependencies (they are vendored).
- test/helpers/literal-collectors: `DIR_LANG` gains `zig`, so literals under
`languages/zig/**` are validated against the Zig grammar alone rather than
against every grammar.
- walkers.ts `isShapeLike` doc: Union IS included (via isClassLike, wired by
Zig's union member container); Typedef remains the only deferred one.
- language-config `ZigBuildZonConfig.pathDeps` doc: values are the raw
`.path` strings; the resolver normalizes.
Tests: zig-import-resolver (+1), zig-extractors (+3).
* fix(zig): address third gitnexus-check review pass
- language-config `parseZigBuildZon`: the `.dependencies = .{` header and
the per-entry `.<name> = .{` headers are matched only OUTSIDE string
literals (per-offset string mask + `matchZonHeader`). A `.name` or
`.description` value spelling `.dependencies = .{ .fake = .{ .path = … } }`
used to be taken as the block and returned the fake dep instead of the
real top-level one.
- import-resolvers/zig: an absolute import (`@import("/foo.zig")`) returns
null. The path walker skipped every empty component, so the leading `/`
vanished and `/foo.zig` resolved as importer-relative `src/foo.zig` — an
in-repo edge for an import Zig rejects as outside the module path.
- tree-sitter-languages.test.ts: the Zig parsing case gates on the PACKAGE
being installed (`createRequire().resolve`, minus a deliberate
`GITNEXUS_SKIP_OPTIONAL_GRAMMARS` opt-out), not on `isLanguageAvailable`,
which is false for absent AND for installed-but-broken bindings — so a
load failure (ABI mismatch, bad export) now fails the test instead of
skipping it, as the comment already claimed.
- walkers.ts `isShapeLike` doc: `Union` sits in `isClassLike` because that
is the label set the ownership walkers consult, not because unions
inherit — Zig has no inheritance and no heritage hooks. The previous
wording ("inheritance-capable owner") said otherwise.
- Not re-fixed (already addressed in the second pass, findings carried
over): "receiver = any parameter named self" — `interpretZigTypeBinding`
only sources a first-position parameter as `self`; `zigReceiverBinding`'s
doc now states that invariant. "`DIR_LANG` has no zig entry" — it does.
Extended one level out: `BASENAME_LANGS` (`zig.ts`) and `PREFIX_LANGS`
(`ZIG_`) map to the Zig grammar too, so extractor configs and the
export-detection set are validated against Zig alone. That immediately
caught a dead `childForFieldName('parameters')` in
method-extractors/configs/zig `zigParameterList` (there is no such field;
the named-child lookup was already the one doing the work) — removed.
Tests: zig-import-resolver (+2: absolute path, header inside a string);
both fail on the previous code.
* fix(zig): address fourth gitnexus-check review pass
- language-config: `parseZigBuildZon` only accepts a `.path` that is a
DIRECT field of a dependency entry. Nested blocks inside the entry body
are blanked (string-aware, offsets preserved) before the `.path` regex
runs, and a match starting inside a string literal is rejected, so
`.dep = .{ .url = "…", .meta = .{ .path = "x" } }` no longer becomes a
path dep. Regression test in zig-import-resolver.test.ts (fails on the
previous code).
- tree-sitter-languages test: the "grammar is absent" case now drives the
loader's real `source.load()` catch branch — `node:module` is stood in
with a `createRequire` whose require throws MODULE_NOT_FOUND for
`@tree-sitter-grammars/tree-sitter-zig` and delegates everything else —
instead of the `GITNEXUS_SKIP_OPTIONAL_GRAMMARS` opt-out, which has its
own test. It also asserts the opt-out flag is NOT set and that other
grammars still load (non-fatal optional failure).
Not re-fixed:
- "Return type is read from the wrong tree-sitter field": tree-sitter-zig
1.1.2 has NO `return_type` field on function_declaration — the type after
`)` is the `type` field (AST dump: `builtin_type "i32" field=type`; the
proposed `childForFieldName('return_type')` is null for every function).
A pin test in zig-extractors.test.ts asserts both the grammar fact and
that `returnType` is extracted (`void`, `!*Counter`).
- "`DIR_LANG` has no zig entry": it does (added in the first pass and
answered again in the third); the finding is carried over unchanged.
* fix(zig): address fifth gitnexus-check review pass
- tree-sitter-languages test: the Zig "functions, structs, enums, and
imports" case now asserts the `import.source` capture for
`const std = @import("std");` (the fixture's only import), so a query
change that drops Zig import matching fails it instead of passing
unchanged.
Not re-fixed:
- "Return type is read from the wrong tree-sitter field": carried over from
the fourth pass unchanged. tree-sitter-zig 1.1.2 has no `return_type`
field on function_declaration; the return type IS the `type` field, and
the pin test added in the fourth-pass commit
(zig-extractors.test.ts, `childForFieldName('return_type')` is null,
`returnType` = `void` / `!*Counter`) proves it.
- "`DIR_LANG` has no zig entry": carried over unchanged for the third time;
the entry exists since the second-pass commit.
* feat(zig): export fn visibility, opaque containers, named test blocks, member ownership
Ports the parts of upstream PR #305 (closed, unmerged) that our Zig
provider lacked, plus two gaps found while porting.
- `export fn` / `export var` (C-ABI linkage, never `pub`) are exported;
the pub/export predicate is now shared by the export checker and the
method/variable extractors' visibility (`hasZigVisibilityKeyword`).
- `const H = opaque { … }` is a Struct-labelled container (it may own
methods, never fields) in both the structure queries and the scope
query; ZIG_CONTAINER_TYPES is the single source for the extractor
configs.
- `test "name" { … }` blocks are Function nodes named by the string
node WITH quotes, so `test "add"` beside `fn add` cannot merge onto
Function:<file>:add; `test_declaration` joins FUNCTION_NODE_TYPES and
the Zig method config names it in the enclosing-function walk, so
calls inside a test attribute to the test. Anonymous `test {}` and
decl-tests `test add {}` are scopes without a node (an empty-name hook
result stops the walk instead of falling through to the identifier of
the function under test).
- Empty container bodies (`struct {}`, `opaque {}`) no longer mint a
nameless Property: tree-sitter-zig 1.1.2 recovers them as a
container_field with a MISSING identifier; #not-eq? guards in both
queries and the field extractor drop it.
- Owner walk (`findEnclosingClassInfo`): an anonymous container bound
by the enclosing `variable_declaration` takes the binding identifier,
same shape as the Go `type_spec` branch. Before this NO Zig member
had an owner — zero HAS_METHOD / HAS_PROPERTY edges for Zig.
Not ported from #305, deliberately: `builtInNames` (a bare-name call-site
drop filter; `alloc`/`free`/`append`/`print` are the most common user
method names in Zig and `std.*` receivers are already external via the
import binding), `usingnamespace` (removed in Zig 0.15), `@cImport`,
`build.zig` ignore, and the web-app changes.
* test(zig): absent-grammar case owns GITNEXUS_SKIP_OPTIONAL_GRAMMARS
The loader parses the opt-out variable lazily once per module copy, so
under `GITNEXUS_SKIP_OPTIONAL_GRAMMARS=zig` (or `all`) — a supported way
to run — the fresh loader took the opt-out branch and the "not the
opt-out path" assertion failed before the absent-binding path ran.
Clear the variable for the fresh module and restore it in `finally`,
instead of returning early: the branch stays exercised in every
environment. Verified: fails on the previous code under `=zig`, passes
with and without the variable now.
* fix(zig): declare the Union relation pairs — analyze aborted on any union
`gitnexus analyze` exited 1 on every Zig repository that declares a
`union` (including the zig-basic fixture itself): the member-ownership
commit made `union_declaration` a MEMBER_OWNER, so HAS_PROPERTY /
HAS_METHOD edges are emitted FROM a Union node, but `Union` was not in
LINKABLE_LABELS, so the schema's scope-bridge cross product never
generated a `FROM Union` pair and LadybugDB rejected the edge
(`labelPair: "Union|Property"`). Resolver tests stayed green because
they never write to the DB.
- `Union` joins LINKABLE_LABELS (also bridges `Tag{…}` constructor
references); the three hand-written `→ Union` target pairs move to the
generated half, per the STRUCTURAL_PAIR_DDL rule.
- structural-pair-coverage gains an optional-grammar corpus with
zig-basic (`Union|Property`, `Union|Method` sentinels), skipped when
the grammar is absent.
- Rust `union_item` note updated: the three gates it cited are widened.
Note for reviewers: the DDL fingerprint changes (#2808), so existing
indexes are rebuilt on next analyze.
* feat(zig): resolve path deps through the dep's build.zig and src/root.zig
The bare-name resolver only knew `src/<name>.zig` and `src/main.zig`.
`zig init` has written `src/root.zig` for libraries since 0.12, so the
default library layout never resolved. Now: the root the dep's own
build.zig declares (`b.addModule("<name>", .{ .root_source_file =
b.path("…") })`, name-matched module first), then src/root.zig,
src/<name>.zig, src/main.zig. `normalizeZigDepPath` is shared by the
loader and the resolver.
* feat(zig): Const/Variable defs, member imports, receiver typing, generic type constructors
Coverage gaps found by indexing idiomatic Zig against the branch:
- Const / Variable nodes: ZIG_QUERIES had no @definition.const /
@definition.variable, so `pub const VERSION`, error sets and type
aliases were absent and zigVariableConfig never ran. Rules are gated on
the literal `const` / `var` keyword — tree-sitter-zig 1.1.2 parses
statement assignments (`x = 5;`, `x += 1;`, `_ = expr;`) as keyword-
less `variable_declaration`s, and the scope query minted a phantom
local per assignment and one `_` per discard. Container and @import
bindings are skipped via `shouldSkipDefinitionCapture`.
- Imports: `const X = @import("x.zig").X` (named / alias), `const X =
ns.X` where `ns` is an @import binding of the file (promoted to a
named import), and `pub usingnamespace @import(...)` (wildcard, with
`expandsWildcardTo`). All three lost the file-level IMPORTS edge.
- Receiver typing: `var x: T = undefined` / decl literals `const x: T =
.init()` (annotation), `var c = T.init()` / `mod.T.init()` (call
return), `List(u8){}` (instantiation literal); `normalizeZigTypeName`
drops the comptime argument list.
- Generic type constructors `fn List(comptime T: type) type { return
struct {…}; }`: the returned container is a Struct/Union/Enum named
after the fn, owns its members (HAS_METHOD / HAS_PROPERTY), binds in
the module scope beside the Function def, and is emitted ahead of it
so a named import binds the type.
- `export` vs `pub`: `visibility` is now `pub`-only (Zig-module fact);
`isExported` keeps `pub|export` (visible outside the unit, as C's
external linkage). `export fn` without `pub` is not reachable from
other Zig files.
- Extractor configs share `zigContainerName`; ast-helpers' owner walk
learns the type-constructor shape.
Tests: zig-idioms fixture (10 resolver cases), extractor/interpret unit
cases for each rule.
* fix(zig): address sixth gitnexus-check review pass
- Windows absolute `.path` deps (`C:\x`, `C:/x`) return null from
`normalizeZigDepPath` like POSIX ones; a `/`-only check let them
through as repo-relative.
- `parseZigBuildZon` accepts the `.dependencies = .{` header only at
brace depth 1 (a direct field of the file's `.{`), so a same-named
field nested in an earlier struct cannot hijack the block.
- `importsExecuteWhereWritten: false` on the provider: `@import` is
compile-time name lookup (as C `#include`, Rust `use`); a body-level
`@import` is no longer marked `runsOnlyWhenCalled`.
- Namespace imports record the MODULE as `importedName`
(`zigModuleNameOf`: last path segment without `.zig`), per the shared
contract; the local handle stays `localName`.
- Keyword-less `<ident> = @import(…)` (`_ = @import("x.zig")` in a test
block) is a `side-effect` import: file edge, no binding. Only
`const`/`var` declarations bind a name or feed alias promotion.
- `extractZigFunctionName` doc: an empty name is falsy, so the enclosing-
function walk skips the test node and continues to the File; it does
not "end" there.
Not re-fixed: "DIR_LANG has no zig entry" — carried over for the fourth
pass in a row; `test/helpers/literal-collectors.ts` has had `zig` in
`DIR_LANG` (line 91) and `BASENAME_LANGS` since the second-pass commit.
Regression tests: absolute-path spellings, nested `.dependencies`
decoy, namespace/side-effect interpretation, function-scoped `@import`
not deferred (all four fail on the previous source).
* fix(zig): address seventh gitnexus-check review pass
- The scope query's `@import` binding rules are keyword-gated (`"const"` /
`"var"`, first-child anchored) like every other binding rule, and the
keyword-less `<ident> = @import(…)` statement has its own
`@import.side-effect` rule. Tree-sitter queries cannot express "no
keyword child", so that rule also matches the keyword shapes and
`emitZigScopeCaptures` drops those (they are the binding rules'
matches). Behaviour is unchanged from the sixth-pass fix — the existing
side-effect test covers it — the query text now carries the guard the
finding asked for.
Not re-fixed: "DIR_LANG has no zig entry" — fifth pass in a row;
`test/helpers/literal-collectors.ts` has had `zig` in `DIR_LANG` since
the second-pass commit. Left for a human reviewer to close.
* fix(zig): resolve @import of the repo's own build.zig modules (F3)
Bare-name imports were resolved through build.zig.zon path deps only, so
the module a repo's ROOT build.zig declares for itself —
`b.addModule("lightpanda", .{ .root_source_file = b.path("src/lightpanda.zig") })`,
imported by name from 378/567 Lightpanda files — never produced an IMPORTS
edge, and nothing reached through `lp.X` resolved. A repo with a build.zig
but no build.zig.zon got no resolution config at all.
- language-config: `parseZigRootModules` (static scan of the root build.zig:
`addModule("<name>", …root_source_file = b.path("<p>.zig")…)`, and
`createModule`/`addModule` bindings named via `addImport("<name>", m)` or
`.imports = &.{ .{ .name, .module = m } }`; generated / `.url` / computed
modules are skipped) → `ZigBuildZonConfig.rootModules`.
- `loadZigBuildZon` → `loadZigBuildConfig`: reads the zon AND the root
build.zig; null only when neither contributes.
- resolver: root modules are consulted before path deps; std/builtin/root
still never resolve.
- fixtures: zig-idioms gains a Lightpanda-shaped root module (+ decoy
`addOptions().createModule()`); new zig-rootmodule (build.zig, no zon).
Corpus (Lightpanda): IMPORTS 3014→3389 (378 edges to src/lightpanda.zig,
was 0), CALLS 13885→13989, ns.f() 79.3%→83.3%,
param.m() type=ns-qualified 43→46/417.
* fix(zig): import every @import in expression position; resolve @import("x").f()
Both query sets only saw `@import` as the value of a const/var or under
`usingnamespace`, so an @import in any other position produced no file
edge: Lightpanda's `pub const Interfaces = .{ @import("a.zig"), … }`
registration table (288 modules), call arguments
(`CounterEnum("size", @import("ArenaPool.zig").BucketSize)`), comparison
operands (`JsApi == @import("x.zig").JsApi`) and member-call receivers
(`try @import("dump.zig").root(...)`) — 417 of 3,401 in-repo import pairs
had no IMPORTS edge, and the 80 inline-receiver calls resolved 0 times.
Scope query: a catch-all `@import.inline` rule matches every `@import`
builtin; `emitZigScopeCaptures` drops the ones a binding rule (or the
keyword-less side-effect rule) already claimed (by string-node id) so a
bound import is never doubled, emits the rest as side-effect imports once
per distinct source per file, and binds a member-call receiver as a
namespace import whose local name is the builtin's own text — the
`@reference.receiver` text on that call is identical, so the shared
namespace-receiver lookup (Case 1) resolves the member in the imported
module.
ZIG_QUERIES: the three variable_declaration/usingnamespace-anchored
`@import` rules collapse into the same single builtin rule (the structure
phase only skips import matches; one match per builtin keeps
tree-sitter-languages' exact-capture assertion intact).
Lightpanda corpus (zig-corpus-check, before → after): IMPORTS 3014 → 3426,

* feat(zig): model file-structs — a file with top-level fields is a Struct named after the file
In Zig every file is a struct; one that declares top-level fields is an
instantiable type whose name is the file stem (`Page.zig` declares `Page`,
`@typeName` agrees), and its top-level `fn`s taking `self` are its methods.
Lightpanda spells 413 of 567 files this way and, before this, `page.getArena()`
on a `page: *Page` parameter resolved 23 of 993 times (2.3 %) — `impact` on
`Page.getArena` reported 0 callers for 159 call sites, and 2,395 top-level
fields were ownerless Property nodes.
Definition phase: `((source_file (container_field …)) @definition.struct)` +
the class extractor names it from the file path (`zigContainerName(source_file,
filePath)`); top-level fns/fields are owned through the new
`LanguageProvider.resolveFileTypeOwner` hook (consulted by
`findEnclosingClassInfo` when the walk reaches the tree root, and by the
method/field extractors' owner lookup) — ids become `Method:<file>:Page.getArena#0`
/ `Property:<file>:Page.session` with HAS_METHOD / HAS_PROPERTY edges.
Scope phase: `emitZigScopeCaptures` emits a Class scope over the whole file
(same range as the Module scope, nested under it — the pair `canParentScope`
already admits) plus a Struct def anchored on it; member NAME bindings are
hoisted back to the Module scope by `zigBindingScopeFor` so `Page.init()`
(namespace member) keeps working, while ownedDefs stay in the Class scope so
`populateClassOwnedMembers` stamps the owner. The file-level `const Page =
@This();` alias no longer mints a Const (it would shadow the Struct); `@This()`
aliases in type position (`self: *SigHandler` in Sighandler.zig, nested
`Self`) are rewritten to the container name so receivers resolve. A namespace
import of a `.zig` file gets a NAMED twin of the file stem so `x: *Page` in the
importer binds the type as well as the module.
Shared, additive: `resolveFileTypeOwner` hook; `filePath` threaded to
`ClassExtractionConfig.extractName` / `extractOwnerName`; nameless
`definition.struct` passes `getLabelFromCaptures` like `definition.class`
already did (extractor synthesizes the name).
Lightpanda corpus (zig-corpus-check): param receivers typed by a file import
23/993 → 993/993; `self.m()` 99.2 → 100 %; annotated locals 11.6 → 23.2 %;
CALLS 13,885 → 15,689; HAS_METHOD 1,477 → 8,003; ownerless Property 2,395 →
276; Function/Method 8,378/1,518 → 2,562/7,330; no row regressed.
Fixture `zig-filestruct` (Page/Session/Sighandler/util) + unit tests pin the
shape, the stem naming, the alias rewrite, the namespace twin and the
unchanged namespace-file behaviour.
* test(zig): expression-position import case sees the file-struct type twin
* fix(zig): stop reading member calls `x.f(arg)` as direct calls named `f`
tree-sitter-zig spells `field_expression` as `object:`/`member:`; the shared
callable-flow reader only knew `property`/`field`/`method`, so every Zig
member call collapsed to a DIRECT call named after the member and the
solver fanned each argument out to every same-named callable
(4,761 cap warnings on Lightpanda, `Global.deinit -> Global.deinit`
self-loops through `pub const release = deinit;`).
Shared (grammar-neutral, receiver-gated):
- `memberParts` also reads `member` (only C/C++ `offsetof_expression` and
JS `class_body` expose that field, without a receiver field).
- A member call is a field-stored-callable invoke only when a MEMBER store
(`o->run = handler`, `self.f = target`) or a declared callable-typed field
is visible — a same-named plain binding no longer gates it.
- `direct-callee-name` requires a direct designator: `.init(x)`,
`' '.join(x)`, `string.Join(x)` name no callee to seed by simple name.
Zig: formals are numbered without the leading `self`, so `r.run(target)`
joins `cb` and yields `Runner.run -> target`.
Goldens for python/csharp regenerated: the only drift is the dropped
`direct-callee-name` on `' '.join(...)`, `text.strip().ljust(...)`,
`string.Join(...)`.
Lightpanda: cap-warnings 4761 -> 2, cvf self-loops 10 -> 0,
CALLS 13885 -> 13857 (28 removed, all callable-value-flow: 10 self-loops,
17 same-name fan-out, 1 lost `on -> TypeErased.start`; +1 correct
`Arena.alloc -> allocator`).
* fix(zig): bind container field types so `self.field.m()` resolves (F5)
A container's field types were never bound on its Class scope: the scope
query's `container_field` rule captured only the name, and
`emitZigScopeCaptures` synthesized no `@type-binding.field` group. The
compound resolver reads member types from that scope
(`typeOfMemberOnClass` → `classScope.typeBindings.get(field)`), so
`self.session.name()`, `self.counter.incr()` — Lightpanda's dominant
cross-object call shape — resolved 9 of 2803 times (0.3 %).
- query.ts: capture `type: (_)? @declaration.field-type` on
`container_field` (enum variants have none).
- captures.ts: per typed field, push a `@type-binding.field` group (name =
field, type = the type text, `@This()` aliases rewritten to the container
name like parameter types); anonymous inline containers are skipped. The
binding lands on the container's Class scope — the file's Class scope for
a file-struct — since `zigBindingScopeFor` hoists only declaration names.
- query.ts/captures.ts: `const page = self.page;` / `var s = self.session;`
one-level field aliases become `@type-binding.alias` bindings whose "type"
is the RHS path; the resolver's member-alias branch re-resolves it as a
receiver chain. Import aliases (`const Counter = counter.Counter;`) are
dropped — they are named imports.
- interpret.ts: `@type-binding.field` → 'annotation',
`@type-binding.alias` → 'assignment-inferred' (an annotation on the same
binding wins).
Corpus (Lightpanda, zig-corpus-check): self.field.m() 11/2803 (0.4 %) →
1433/2803 (51.1 %); ident.m() bound=local-field-access 29/1902 (1.5 %) →
307/1902 (16.1 %); chain.m() 146/5022 (2.9 %) → 642/5022 (12.8 %);
CALLS 15838 → 18066. self.m() / free f() / ns.f() unchanged.
Tests: unit (zig-extractors) — one @type-binding.field per typed field with
sigils stripped and aliases rewritten; the binding hosted on the container's
Class scope (file-struct: the file's Class scope, not Module) with the
written spelling as declaredSpelling; field aliases bound to the RHS path
and never for import aliases. Integration (zig-idioms `holder.zig`,
zig-filestruct `Page.zig`): `viaField → incr` ×2 into counter.zig,
`viaAlias → get/twice`, `sessionName → name` / `sessionLabel → name` into
Session.zig. All fail without the change. The optional-payload capture
`if (self.opt) |c| c.incr()` is not asserted (F6).
* fix(zig): `pub const X = @import(…)` at file scope republishes X (reexportsName)
Lightpanda's `lightpanda.zig` is one long list of `pub const Arena =
@import("Arena.zig");`, and most files name their types through it (`const
lp = @import("lightpanda"); const Arena = lp.Arena;`, `arena: *lp.Arena`).
The scope side treated those bindings as plain imports of the hub file, so
the hub never published the names it re-exports and a third file's `const
Arena = lp.Arena;` (promoted to a named import of `Arena` from the hub) found
nothing.
`emitZigScopeCaptures` now marks named/alias import groups whose declaration
is a file-level `pub const` — the `@import(...).X` form, the alias promotion
`pub const Bar = ns.Bar`, and the file-struct type twin of `pub const Arena =
@import("Arena.zig")` — and `interpretZigImport` sets the shared contract's
`reexportsName: true` on them (the Python `__init__.py` shape, consumed by
`buildReexportClosures`). Private and fn-local bindings stay unflagged.
Not covered here: a receiver ANNOTATED with the dotted hub path (`arena:
*lp.Arena`) — Case 3 of the receiver-bound pass looks the member up with
`findExportedDef`, which only sees locally declared names; following
re-exports there is a shared change left for a follow-up.
* fix(zig): type receivers through `const X = <type expr>;` aliases (F7)
`const LocalAlias = Local;`, `const T2 = Thing;` (alias of an alias/import)
and `const B = util.List(u8);` (an INSTANTIATED generic type constructor)
were plain `@declaration.variable` bindings, so `LocalAlias.mk()`,
`var l = LocalAlias.mk(); l.go()`, `T2.make()`, `B.init()`, `B{}` and
`var x: B` all typed nothing (review repro r3-flow b1..b9; Lightpanda:
`pub const Proto = HtmlElement;` x68, `const Allocator = std.mem.Allocator`
x104, `pub const KeyIterator = GenericIterator(...)`, fn-local
`const R = ...(...)`).
Model: a `@type-binding.alias` binding of the alias NAME to the value's type
text — Rust's `let x = y` / JS's `const B = Foo`, source
'assignment-inferred' — NOT a TypeAlias def. Reasons: (1) the shared
machinery already chains typeBindings (`followChainedRef` in the extractor,
`followChainPostFinalize` after propagation), so `var l = LocalAlias.mk()`
and `var x: B` reach the target through the alias with no new shared code;
(2) nothing shared follows a `TypeAlias` def to its target — `isShapeLike`
only makes the alias itself a member owner (TS object-type aliases) — so a
relabel would have needed language-named shared code; (3) graph node ids
are UNCHANGED: every alias stays `Const:<file>:X`. `normalizeZigTypeName`
already drops the comptime arguments, so `util.List(u8)` binds `util.List`
and resolves through the namespace import (Case 3). The identifier /
member shapes also take `var` (`var cur = orig; cur.go()` — the cursor
idiom, same binding as Rust's `let x = y`).
Heuristic, stated as such: a CALL value is kept only when the callee's last
identifier is TitleCase (Zig's naming convention for types), because the
grammar cannot tell `util.List(u8)` from `util.makeThing()` and the latter
belongs to the call-return rules; the call-return group is dropped for the
same TitleCase shape so the two never race on match order. Import bindings
(`const Stack = @import("x.zig").Stack`), promoted namespace-member aliases,
enum/decl literals (`.foo`) and the `type:` annotation of
`var b: T = undefined;` are excluded.
Not done: the two-hop `pub const bridge = js.Bridge(T); bridge.accessor()`
chain. `js.Bridge` is a Function that RETURNS `bridge.Builder(T)` (a call,
not a container), so the alias binds `js.Bridge`, Case 3 finds a Function
with no members in js.zig, and Case 3b is skipped for a namespace head.
Following that hop needs a namespace-member return-type route in shared
code (or a Zig `resolveQualifiedReceiverMember` hook that re-implements
member lookup without the model); left for a follow-up.

* fix(zig): one alias rule set — F7's alias rules subsume F5's field-access alias rules
* fix(zig): type locals through try/catch/orelse, return types and payload captures
F6 of the gitnexus-check review. Three gaps in the value flow that types a
local receiver, all measured on Lightpanda:
1. `@type-binding.call-return` needed the `call_expression` as the DIRECT
value child, so `const p = try Page.init(…)` (2,551 sites), `… catch
return` (410) and `… orelse return` typed nothing. The rule is now one
keyword-gated declaration match; `emitZigScopeCaptures` unwraps `try`,
`catch`, `orelse` and parentheses (`zigUnwrapValue`) and decides what the
value types (`zigCallReturnTypeOf`): a module-level receiver still names
the type (`Counter.init()` → Counter, Rust `Foo::new()`); a free call
binds the callee name (`makeThing`); a member call on a fn-LOCAL receiver
(parameter / local / payload — Zig forbids shadowing, so "declared in the
fn" is exact) binds the compound `node.asElement()` the shared resolver
walks to the method's return type — instead of typing `el` as `Node`. A
TitleCase callee (`List(u8)`) is a type constructor and binds nothing.
2. No `@type-binding.return` existed. `fn make() !*Thing` now binds
`make ↦ Thing` in the enclosing scope (Module for free fns, the container's
Class scope for methods, where the compound resolver reads it). Builtins,
`type`, `@TypeOf(…)` and comptime type parameters (`?*T`) bind nothing;
`@This()` / `Self` returns name the container. `normalizeZigTypeName` now
strips the error union BEFORE the payload's sigils, so
`Allocator.Error!*Page` → `Page` (it used to leave `*Page`).
3. Payload captures had no binding at all. `populateZigRangeBindings`
(registered as `populateRangeBindings`) types `for (items) |it| / |*it|`,
`for (items, 0..) |it, i|`, `if (opt) |v|`, `if (call()) |v|`,
`while (it.next()) |x|` from the SUBJECT's written type minus one layer
(`[]T` element, `?T` payload) — declining when the layer is not visible
(`ArrayList(T)`) — and the same projection for `const t = items[i]` /
`opt.?` / `ptr.*`. `catch |err|` and `switch` prongs are skipped.
Corpus (Lightpanda, gate before → after): CALLS 15838 → 17853;
`ident.m() bound=local-try/catch/orelse` 11/1298 → 584/1298;
`local-call` 159/1282 → 398/1282; `payload` 82/1085 → 233/1085;
`other-recv:call_expression` 5/991 → 457/991; `local-other` 271 → 364;
`self.m()` 100 %, `free f()` 97.5 %, `ns.f()` 83.4 % unchanged; nothing down.
Not covered: `const t = ns.f()` (a namespace fn's return type across files —
Case 3 has no path from a namespace head to a callable's return binding),
and expression receivers (`items[i].run()`, `o.?.run()`).
* fix(zig): resolve leftover fixture merge markers (Page.zig)
* fix(zig): reconcile F6 value inference with F7 aliases and F5 field bindings
- A fn-local TitleCase receiver (`const R = generic.List(u8); var l =
R.init();`) is a type alias (F7), not a value local: `R.init()` names the
type `R` like `Counter.init()` does at module level, so `l` chains
R → util.List → push. F6's local-receiver rule now excludes TitleCase heads.
- The F6 unit helper only collects the value-inferred / return kinds it
owns; F5 field and F7 alias bindings for the same names are asserted in
their own suites.
* fix(zig): give function-local and anonymous containers an identity (F8)
`const R = struct {…}` declared inside a fn (Lightpanda's reflection.zig
has ~20, one per builder) all collapsed onto one `Struct:<file>:R` with one
`R.get`; anonymous containers (`std.sort.pdq(…, struct { fn lessThan … }
.lessThan)`, `const byte_size = struct { fn it … }.it;`, `?struct { min,
max }` field types) had no identity at all, so their fns were OWNERLESS
Methods (`Method:<file>:lessThan#3`) that collided across a file.
`zigContainerName` now yields the graph IDENTITY on both phases:
- function-local named: `<enclosing callable>$<name>` — `Reflect.string$R`
(Java local-class `$` chain; `populateClassOwnedMembers` leaves it whole);
- anonymous: `<host>$<ordinal>` — `build$1`, `Outer$1`, `Page$1`
(javac's `Outer$1` numbering per host, in source order);
- a `test` host is keyed `test@L<line>` (its string does not survive the
class extractor's qualified-name normalization).
`zigContainerBindingName` keeps the spelling code writes (`R`) for scope
bindings and `@This()` alias rewrites (`@declaration.binding-name`).
Structure phase: bare `(struct|enum|union|opaque_declaration)` rules mint the
local/anonymous nodes via the class extractor; `shouldSkipDefinitionCapture`
keeps exactly one rule per container (`zigContainerAnchor`); a new
grammar-neutral `resolveContainerTypeOwner` provider hook lets the shared
owner walk name a container from context, so `Method:<file>:Reflect.string$R
.get#0` and its HAS_METHOD source agree by construction. Scope phase: the
wrapper group splits name/binding-name for locals and anonymous containers
get synthesized `@declaration.<kind>` defs (`is-synthetic`).
Lightpanda: ownerless Methods 14 → 0, fns without a node 55 → 0, ownerless
Properties 276 → 5, HAS_METHOD 8003 → 8074, HAS_PROPERTY 7275 → 7403,
CALLS 15838 → 15857, Struct 1905 → 2199; no resolution bucket dropped.
* fix(zig): re-add the implicit receiver on the call side so both method-call spellings reach the callback formal
`extractFunctionParameters` sliced the leading `self` off the formals, which
lined up `r.run(target)` (target@0 ↔ cb@0) but lost the explicit spelling
`Runner.run(&r, target)` (&r@0, target@1 ↔ cb@0): the callback never joined
its formal and `run → target` was missing (PR #1432 review by koriyoshi2041).
Formals are numbered once per function while the receiver differs per call
shape, so the fix lives in `extractCallArguments`: keep `self` as formal 0
and prepend the receiver as actual 0 when the callee is a member call on a
VALUE receiver — chain head is a fn-local name that is not TitleCase, the
same value-vs-type rule F6 uses. Namespace / type / decl-literal receivers
(`Runner.init(cb)`, `helpers.apply(cb)`, `List(u8).init`, `.init(cb)`) get
no prepend. Known residual gap, documented: a module-level value receiver
(`global_runner.run(cb)`) is not fn-local and still misses.
Tests: the F2 integration case now asserts both spellings plus a namespace
call; the unit contract pins `self@0, cb@1` and the per-call actual index.
* fix(zig): address eighth gitnexus-check review pass
- Named dependency modules: `parseZigBuildModuleRoots` scanned
`addModule("<name>", .{ … })` with a `[^}]*` regex, so a nested field
before `.root_source_file` (`.imports = &.{ .{ … } }`) ended the match
at the inner `}` and demoted the module to an unnamed fallback — the
first exe/lib root in the file then answered `@import("<name>")`. The
named lookup now walks the balanced `addModule(…)` argument list
(same scanner as `parseZigRootModules`, comment-stripped, string-aware);
the unnamed fallbacks are unchanged. Regression test in
`zig-import-resolver.test.ts`.
- Type-position `@import`: `var x: @import("m.zig").T = undefined;` was
read as an import binding of `x` on both sides — the query rules match
the `type:` child like a value, and `isZigContainerOrImportBinding`
scanned every named child — so `x` was never declared and became a
named import of `T`. The helper now skips the `type:` field, and
`emitZigScopeCaptures` drops binding-rule matches whose `@import` sits
in the annotation (`isZigTypePositionImport`) without claiming the
source, so `x` binds as a variable and the file edge survives as a
side-effect import. Regression tests in `zig-extractors.test.ts`
(variable extractor + scope captures).
- Union in the class-capture skip guard: the parse-worker's inline
class-like predicate lacked `Union`, so a `Union` definition bypassed
`shouldSkipClassCapture` unlike every other `ClassLikeNodeLabel`.
Added the label; no Zig behavior changes (Zig defines no skip hook), so
no test.
- File-owned method ids in `findEnclosingFunctionId`: the arity lookup
used `findEnclosingClassNode` while the owner came from the file-owner
aware `cachedFindEnclosingClassInfo`, so a Zig file-struct's top-level
fn produced `Method::Page.get` without the `#<arity>` suffix. It now
uses `findEnclosingClassNodeOrFileOwner`, the definition-phase lookup.
Consistency fix only: `ParseWorkerResult.calls` / `.assignments` (the
sole consumers of this id) are merged but not read since #942 — CALLS
edges come from the scope pipeline, whose ids were already right — so
no observable graph change and no test.
Not re-fixed:
- `test/helpers/literal-collectors.ts` `DIR_LANG` has no `zig` entry
(raised for the seventh time): the entry exists (`zig:
SupportedLanguages.Zig`, added by the second-pass commit), so
`languages/zig/**` literals are already validated against the Zig
grammar alone; documented in the PR body since the fifth pass.
* fix(zig): keyword-gate the constructor type-binding rules
The three `@type-binding.constructor` rules (`const p = T{…}`, `mod.T{…}`,
`List(u8){…}`) matched any `variable_declaration` with an identifier and a
`struct_initializer`, keyword or not — and tree-sitter-zig 1.1.2 parses a
re-assignment `p = T{…};` (and `_ = T{…};`) as the same node type. So an
assignment minted a constructor binding for `p` in its own block, and one
for `_`. Zig's static typing makes the extra binding redundant (`p`
already carries its type from its declaration: annotation, constructor or
inferred value), so it cost little, but it declared nothing and stood out
against every other binding rule (`@declaration.variable`, the import
rules, the call-return rules), which are keyword-gated for exactly this
shape. Split each rule into `"const" .` / `"var" .` variants, like the
call-return rules.
Regression test in `zig-extractors.test.ts`: `p = T{…}`, `q = mod.T{…}`,
`l = List(u8){}` and `_ = T{…}` after their declarations yield only the
three declaration bindings (fails on the previous query). The zig,
callable-value-flow, grammar-literal and tree-sitter-languages suites are
unchanged.
Raised twice by gitnexus-check (passes on 2026-08-18 12:42 and 12:56).
* fix(zig): re-baseline the callable-flow capture fingerprints, keep `await f<T>(x)` a direct callee
The `benchmarks (GITNEXUS_BENCH)` CI job gates two capture fingerprints
that this branch's shared callable-flow change (3e62b99a) moved without
re-baselining: `bench/python-scope/baseline-fingerprint.txt` and four
languages in `bench/scope-capture/baselines.json` (csharp, cpp,
typescript, kotlin). Both `--check` runs pass on origin/main and failed
on this branch; every other language matched its baseline on the same
run.
Drift, verified by dumping the canonical matches on both trees:
- csharp / kotlin / python: exactly the intended change — a MEMBER call
(`string.Join(x)`, `.forEach { }`, `' '.join(x)`, `.ljust(w)`) no
longer carries `direct-callee-name`; the argument fact is unchanged.
- cpp: `choice.select(1)` (cpp-deleted-overload) drops an INDIRECT
invoke + its synthetic `@reference.call.free` that were gated only by
the same-named free `select` binding; the site is a genuine method
call already captured as `@reference.call.member`. capture_groups_fp
4605 -> 4601.
- typescript: `await svc.verify<T>(x)` (member) and `initializer()(cb)`
(call-of-call) drop the name as intended. But `await verifyToken<T>(x)`
— a DIRECT call — lost it too, because tree-sitter-typescript parses
`await f<T>(x)` as `call_expression(function: await_expression(f),
type_arguments, …)` and the new direct-designator gate saw an
await_expression, not `f`. `wrappedExpression` now unwraps
`await_expression` (no named field, so the field-based unwrap missed
it), restoring parity with main for the direct spelling while the
member spelling stays nameless. Regression test added; it fails
without the unwrap on both assertions.
Gates run locally: scope-capture --check (15 languages), python-scope
--check, import-target --check, tsc, eslint, prettier, the callable-flow
/ golden / tripwire / resolver test files (33 files), full suite with
coverage (82.9/71.5/89.1/86.4 vs 26/23/28/27 thresholds).
* test(zig): fail CI when the optional Zig grammar is absent
`@tree-sitter-grammars/tree-sitter-zig` is an optionalDependency, so every
Zig suite gates on `isLanguageAvailable(Zig)` and the ABI load-smoke accepts
a clean load failure for an optional grammar. Both are the right contract for
a platform with no prebuild, and together they leave a hole: if the grammar
never installed on any CI runner, this PR would merge with all eight Zig
resolver suites plus the structure-phase suite reported green-by-skip, having
never executed the native Zig parser once.
Close it with the `GITNEXUS_REQUIRE_FTS` idiom already used for the FTS
suites. `GITNEXUS_REQUIRE_ZIG=1` declares "this runner has a prebuild, the
grammar MUST be here", and a missing grammar becomes a failure instead of a
skip. tree-sitter-zig@1.1.2 publishes prebuilds for {darwin,linux,win32}-
{x64,arm64}, so the flag is set on two required jobs that all run on covered
platforms: the sharded ubuntu `tests` job and the three-OS `abi-assert` job.
- test/helpers/optional-grammar.ts: the registry mapping a language to its
require-variable, plus `describeGrammarPresence`, a presence assertion that
FAILS when required-but-absent. Deliberately a separate test rather than
flipping the suites from skip to fail: a skipped suite reports success, so
only a failing test can turn "Zig never ran" into a red job.
- parser-loader-abi.test.ts: the optional exemption is revoked for a language
the environment declares required, so an ABI-broken Zig binding fails the
smoke instead of passing as a clean absence.
- optional-grammar-gate.test.ts: pins the two ways the gate could silently
never fire — reading a variable name CI does not set, or accepting a value
CI does not write.
Nothing changes for a run that leaves the variable unset: local runs and any
future prebuild-less platform still skip. Verified both directions --
`GITNEXUS_REQUIRE_ZIG=1` alone: 149 passed, 0 skipped; with
`GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1` forcing the grammar away it fails 2 tests
with an actionable message; with the skip flag but no require flag it is
green-by-skip exactly as before.
Addresses the test-only blocker in the gitnexus-check review of #1432.
* fix(zig): type the optional-grammar gate by grammar key, not language
The gitnexus-check finding on parser-loader-abi.test.ts:155 is right, and
none of the gates caught it: `tsconfig.json` includes only `src/**/*`, so
neither `tsc --noEmit` nor CI typechecks the test tree, and vitest strips
types without checking them. Confirmed with a scoped tsc run over the file:
`error TS2345: Argument of type 'string' is not assignable to parameter of
type 'SupportedLanguages'`.
Not fixed with the proposed `key as SupportedLanguages` cast, which would
assert something false: `listGrammarSources()` yields one row per SOURCES
entry, including variants like `typescript:tsx` that are not enum members.
`isOptionalGrammarRequired` now takes the grammar KEY it is really given,
and the registry keeps a `satisfies Partial<Record<SupportedLanguages,
string>>` so every key we write is still pinned to a real language.
Two new cases cover the failure mode the type error was pointing at — a
registry key that can never match what the ABI smoke passes, leaving the
gate configured-looking and permanently inert: every OPTIONAL_GRAMMAR_ENV
key must be a key `listGrammarSources()` yields and must be marked optional
there, and an unregistered variant (`typescript:tsx`) must not be required
even with the variable set.
Same blind spot, two more latent errors in files this PR adds, both fixed:
`Parser.Language` is not an exported member (use the `setLanguage` parameter
type, as parser-loader-abi.test.ts already does), and the `ParsedImport`
filter did not narrow the union, so `localName` was read through a `!` on an
arm that has no such property — now a type predicate. The one remaining
error under the same probe, in `resolvers/callable-value-flow.test.ts:319`,
predates this branch (authored 2026-07-17, on main) and is left alone.
structural-pair-coverage's optional-grammar case switches from
`it.concurrent.each` to `it.concurrent.for`: only `for` passes the test
context as a second argument (`each`'s callback is `(...args: T[])`), and
that context carries the dynamic `skip()` the per-language gate calls.
Behaviour is unchanged — grammar present: 10 passed; grammar forced away:
9 passed, 1 skipped.
Whole test tree typechecking is a separate, much larger job: the same probe
over `test/**` minus fixtures reports 734 pre-existing errors across the
repo. Out of scope here.
* fix(zig): address tenth gitnexus-check review pass
- `normalizeZigDepPath`: normalize backslashes BEFORE the absolute-path
check. A UNC dep (`\\server\share\dep`) used to slip past the check and
normalize to the repo-relative `server/share/dep`; root-relative `\dep`
had the same hole. Both now return null. Regression case added to the
absolute-spellings test with the files those misreadings would resolve.
- `bindPayloads`: a pointer capture `for (pages) |*p|` now records `*Page`
(declaredSpelling) instead of `Page` — the `*` is an anonymous payload
child before the identifier. Method dispatch is unchanged (`rawName`
strips the sigil), but a deref projection `const q = p.*;` now sees the
pointer layer. New fixture fn `viaPtrCaptureDeref` + assertion; fails on
the previous code (verified by stashing the src fix).
- `optional-grammar-gate.test.ts`: renamed the `typescript:tsx` case — the
key IS a registry row; what makes it inert is the missing gate entry. Now
also asserts a key no registry yields.
- `structural-pair-coverage.test.ts`: header updated — ten tables (not
eleven) are absent from every rule's target side; `Union` left the set
when Zig made it linkable.
- `language-classification.ts`: doc comment now names zig in the
experimental set (added after Ring 1).
Not re-fixed (invalid findings):
- "owner-hook contract wired to an undeclared variable": stale-diff read —
`findEnclosingClassInfo` declares `resolveFileTypeOwner` /
`resolveContainerTypeOwner` as optional parameters (ast-helpers.ts:905,
917) and parse-worker threads them at every call site; tsc compiles clean.
- "optional Zig grammar added unconditionally to the parsing fixture
suite": the cited block only `fs.readFile`s the committed fixture file to
assert it is non-empty — no parser or grammar load is involved.
* fix(scope-resolution): mark construction-site CALLS edges in reason (opt-in), enable for Zig
PR #1432 human review, item 2: a Zig struct literal `T{ .f = x }` (no
parens) is modelled as a CALLS edge to the type — the Rust `T { .. }` /
Go `T{}` shape — and nothing on the edge told it apart from an invocation
(`get_next_spawn → SpawnRequest` from seven `return SpawnRequest{ … }`).
`ScopeResolver.markConstructionSites` (default off): when set, the edge
emitted for a `callForm === 'constructor'` site gets ` (constructor)`
appended to its reason, in both emit paths — `local-call (constructor)` /
`import-resolved (constructor)` in the free-call fallback and
`scope-resolution: call (constructor)` in the reference bridge. The Zig
resolver opts in. `Reference` gains an optional `callForm`, copied from
the site by `buildReference`, so the bridge can see the form.
Why `reason` and not a property or edge type: relationships carry no
arbitrary properties, a new column changes the relation DDL and moves
SCHEMA_FINGERPRINT, and `reason` is the channel the IMPLEMENTS `-pointer`
receiver form already uses. Why opt-in: the unsuffixed strings are a
pinned contract asserted verbatim by the other language suites
(php/cpp constructor calls expect exactly `import-resolved`); every
non-Zig edge stays byte-identical.
Tests: `references-to-edges-call-form.test.ts` pins both vocabularies
and the default-off behaviour; `zig.test.ts` asserts
`Reflect.string → Accessor` / `Reflect.url → Accessor` carry
`local-call (constructor)` next to a plain invocation, and that every
marked edge targets a Struct.

fix: close the nine follow-up review findings from #2856 (routes, receiver typing, truncation honesty) (#2899)
* fix(typescript): a type parameter shadows a declared type of the same name (W2-8)
First item of wave 2, promised to the reviewer on #2856.
`export function unwrap<Result>(value: Result): Result` names the PARAMETER, not
the `interface Result` beside it — tsc resolves both annotations to the
parameter. The type-reference capture that makes a contract answerable ("what
breaks if I remove this field?") had no notion of a parameter binding, so every
annotation mentioning `Result` inside `unwrap` minted a `USES` edge into the
interface, at the same confidence as a real consumer and indistinguishable from
one. Measured on the new fixture: `unwrap` produced TWO false edges while the
genuine consumer produced one.
Blast radius is every generic whose parameter name collides with a declared
type, and the colliding names are ordinary choices for both: `Result`, `Key`,
`Value`, `Item`, `Node`, `Options`, `Config`, `Props`, `State`, `Response`.
TWO HALVES, and the first is why upstream's fix could not reach this. #2833
introduced `bindsTypeParameter` for the CALL-receiver path, where a workspace
`class T` was answering for `<T>`. Reusing it here changed nothing at first, and
the reason is its own documented contract: `@declaration.type-parameters` was
captured for class/interface declarations ONLY, so a generic FUNCTION recorded
no parameter list and the predicate correctly returned false — absence is not
evidence. The data was missing, not the logic. So:
- TYPESCRIPT_SCOPE_QUERY now captures type parameters on `function_declaration`,
`generator_function_declaration` and `type_alias_declaration`;
- the graph bridge consults `bindsTypeParameter` before emitting `USES`.
Both are load-bearing — removing either one fails the fixture.
The fixture carries two controls, because the obvious wrong fix is to stop
emitting: a genuine consumer of the interface must still link, and a generic
whose parameter does NOT collide must still link its real reference. Both are
asserted, and the "genuine consumer" case is asserted FIRST so the absences
below it cannot pass vacuously.
SCHEMA_BUMP 53 -> 54: parse-time capture change. A warm cache replays defs with
no parameter list, so the guard reads nothing and the feature is inert while
looking implemented.
Capture fingerprint re-baselined with justification. NO NEW CAPTURE NAME —
diffing the capture-name sets against the wave-1 branch returns empty; the tag
existed and now fires on more declarations. capture_groups_fp 2338 -> 2371,
fixture_count 151 -> 152, scaling 1.06 < 1.5, and JavaScript's fingerprint does
not move at all, which is the check that this is the TS declaration rules rather
than something broader.

* fix(analyze): close the four false-success paths in the graph-write-collapse guard (W2-6)
Second wave-2 item, promised on #2856. All four were reported; all four
reproduced by reading the code they name.
(a) A SAME-COMMIT RE-RUN REPORTED SUCCESS FOREVER. Every other meta-driven
trigger — schema fingerprint, PDG mode, runner identity, CJK segmentation,
embedding dims — has a block that forces a rebuild before the
`alreadyUpToDate` fast path. `graphWriteCollapsed` had none; `grep -rn` found
writes and no reads. So the one state meaning "most of your edges are gone"
was the one state that repaired itself only if the user happened to pass
`--force`. Now forces a full rebuild, and forcing is right rather than merely
re-running: the persisted graph disagrees with what the pipeline produced, so
an incremental pass over unchanged files would write nothing and re-stamp the
same broken index as fresh.
(b) AN INCREMENTAL RE-RUN ERASED THE STAMP. `saveMeta` is a full atomic
overwrite, and the field was spread in only when the CURRENT run had a
verdict. `undefined` meant two different things at that site — "full run, no
collapse" (a positive all-clear) and "incremental write, not comparable" (no
opinion) — so the second case silently dropped `graph-write-collapsed` from
meta.json while the edges were still missing. Now three-way: stamp on
detection, CLEAR on a healthy full run, CARRY FORWARD when there is no
verdict. That is the shape `branch: branchLabel ?? existingMeta?.branch` two
lines away had all along.
(c) THE SERVER PATH NEVER CONSUMED IT. `analyze-worker-ipc.ts` projects the field
"so a server-side caller sees the same degraded outcome the CLI does" — but
nothing read it, so the comment described an intention and every collapsed
run reported `complete` to the UI and to every API consumer. Now reports
`failed` with the counts and the remedy, matching the CLI, which prints
`Repository indexed INCOMPLETELY` and exits non-zero. A consumer that reads
"complete" will query the index and get confident wrong answers.
(d) --pdg ROWS MASKED TOTAL STRUCTURAL LOSS. `expected` counts the in-memory
graph plus the streamed STRUCTURAL manifest; the streamed PDG layers never
enter `graph.relationshipCount`. But `persisted` was `stats.edges`, a count
of EVERY `CodeRelation` row, and PDG writes into that same table. With 1,000
structural edges expected and 4,000 PDG rows persisted, losing every
structural edge still read `persisted = 4000`, cleared the ratio, and stayed
silent — on exactly the large repos `--pdg` is used for.
Worth recording that the OBVIOUS fix does not work. Padding `expected` with
the PDG rows makes the two universes match but leaves the ratio judging a
minority population: 4,000 of 5,000 still clears 0.5. I wrote that first, and
the test I wrote to prove it failed. Only comparing structural against
structural asks the question the check exists to ask, so `getLbugStats` gains
a `structuralEdges` count excluding `PDG_EDGE_TYPES`. `TAINT_PATH` is
deliberately NOT in that set — it is a whole-program Function→Function edge
persisted by the normal emit, so it is structural and stays counted on both
sides.
`index-freshness-graph-collapse.test.ts` had pinned the masking as correct
(`detectGraphWriteCollapse(1000, 4000)` → undefined, "PDG layers write into
the same table, so persisted > expected is normal"). True about the table,
and it licensed the hole. Replaced with the case that matters and a note on
why the fix is at the caller.
The new `structuralEdges` assertion in `lbug-core-adapter` is there because the
failure mode is silent: the query sits in a try/catch that yields `undefined`,
and `undefined` makes the collapse check decline to compare — so a typo in the
Cypher would throw nothing, fail nothing, and switch the guard off. Verified
against a real LadybugDB and mutation-checked by breaking the query.

* fix(processes): make process selection insertion-order invariant (W2-5)
Third wave-2 item. Reproduced before fixing: two equal three-step flows with
`maxProcesses: 1` select `handleAlpha`; inserting the identical nodes and CALLS
edges in reverse select `handleBeta`. Same repository, same commit, a different
persisted graph — so a filesystem that enumerates differently, or an incremental
run that reorders assembly, silently changes what the tool reports.
Four sorts ranked by score or length alone and returned 0 on a tie.
`Array.prototype.sort` is stable, so a 0 preserves INPUT order, which traces
back to `graph.iterNodes()`. Under `maxProcesses` capping that decided which
`Process` and `STEP_IN_PROCESS` nodes were persisted at all. Each now falls
through to a totally-ordered, content-derived key — node id for entry points,
the joined path for traces.
WHAT IS ACTUALLY VERIFIED, stated precisely because "four fixes" would overclaim:
- the ENTRY-POINT sort is individually mutation-verified;
- the two DEDUP sorts are collectively mutation-verified;
- the TRACE-RANK tiebreak is NOT individually observable, and the source says
so. The dedup sorts already impose a total order on the list that reaches
it, so removing it alone fails nothing. Kept as defence in depth: it cannot
misbehave — it only makes an already-deterministic order explicit — and it
is what stops a change to dedup ordering from silently re-opening this.
Finding that out took two fixtures. The first (three chains, three entry points)
is separated by the entry-point sort before trace ranking is reached, so it never
exercises the trace comparator at all; the second gives ONE entry point two
equal-length branches to different terminals, which is the only shape where the
trace comparator decides. Both are kept — they gate different sites.
The invariance tests assert the INVARIANT rather than any single sort, so they
cover all four sites and any future one without needing to know where they are.
Three assertions: same selection under a cap, identical set uncapped, and
identical ORDER — the last because order is what the cap consumes, so a set-only
assertion would pass while the defect persisted.

* fix(impact): UNKNOWN dominates a mixed candidate set, instead of reporting the known floor (W2-4)
Fourth wave-2 item. The all-UNKNOWN branch here was reasoned about carefully and
is correct — its comment even names the two ways a set can be all-UNKNOWN. The
MIXED case fell straight through it.
`RISK_ORDER` is `['LOW','MEDIUM','HIGH','CRITICAL']` and has no `UNKNOWN` entry,
so `indexOf('UNKNOWN')` is -1 and an UNKNOWN candidate can never win the reduce.
An ambiguous name with one caller-less candidate (UNKNOWN, per the round-1 fix)
beside one single-caller candidate (LOW) reported `maxRisk: 'LOW'` — a confident
floor over a set containing an interpretation nobody measured. That is the same
false-safe the all-UNKNOWN branch exists to prevent, one case over, and it
surfaced in the UI as "Max blast radius N (LOW risk)".
`maxRisk` answers "how bad could this be?", and an unresolved candidate could be
CRITICAL — so any UNKNOWN in the set makes the aggregate UNKNOWN. Narrowing it
that way would normally cost information, so the measured part travels alongside
as `knownMaxRisk`, present only when the two differ: absent on a fully-resolved
set, where it would duplicate `maxRisk`, and absent on a fully-unknown one, where
there is no measured part. A reader gets "at least LOW among what resolved, and
one interpretation could not be walked at all", which is strictly more than
either value alone. The human-readable message says the same thing.
The seed gained a mixed pair because the existing one could not reach this: both
its twins are caller-less, so it only ever exercises the all-UNKNOWN branch —
which is precisely why the gap survived a round of review. Three assertions,
both halves mutation-verified.
`eval-server.ts` needs no change: it renders `result.maxRisk ?? 'UNKNOWN'`, so it
now shows UNKNOWN where it previously showed the floor.

* fix(routes): track ternary polarity in dispatch guards, so a selected verb cannot be inverted (W2-9)
`if ((req.method === 'GET' ? false : true) && pathname === '/api/i')` emitted
`GET /api/i` — the one method that branch guarantees the request does NOT have.
A ternary SELECTS between its arms, so a verb inside one is not reached merely
because the whole condition is truthy, but `findVerbInSubtree` descended into
both arms and returned the first verb it saw. Same inversion `!` produced before

feat: close reported graph blind spots in reference resolution, analyze and storage (#2856)
* fix(mcp): report UNKNOWN risk when an upstream impact walk finds no callers `risk: LOW` asserts "safe to change" — a claim ABOUT callers. An upstream walk that resolved none has nothing to base it on: the symbol may be genuinely unused, or reached only through a reference class the index does not record (a property access on a plain object, a bare-identifier read of a module-scope const). Seeding LOW from an empty result is the false-safe signal `anyKnownRisk` already refuses to emit on the ambiguous-candidate path, and that #2687 removed by making an undetermined impactedCount `null` rather than `0`. Zero-caller upstream results now report risk UNKNOWN with a riskNote saying absence of edges is not evidence of disuse. Downstream is untouched: an empty downstream walk reports resolved callees, not safety. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(javascript): emit ACCESSES for bare-identifier reads of module-scope consts A constant read only as a bare identifier — `Math.max(LIMIT, n)`, a default parameter value, `return LIMIT` — minted no reference site at all, because JS captured only `@reference.read.member`, which requires a receiver a bare identifier does not have. So "who uses this constant?", the question behind every dead-code trim and constants refactor, answered with a confident zero in both directions. The rest of the machinery was already in place: `FIELD_KINDS` accepts `Const`, the scope query already declares it via `@declaration.const`, and `read` maps to ACCESSES for any resolved target. This adds the missing capture in VALUE POSITIONS ONLY (call arguments, default-parameter values, return statements) — a blanket `(identifier)` rule would mint a site for every token in the file, which is unaffordable at repo scale and would keep alive the block-local symbols `pruneLocalSymbols` exists to drop. Cross-file readers are NOT yet covered: the site exists and a call through the same import statement resolves, but a value-kind def does not link across the import edge. Recorded as a todo with the investigation. PARSE_CACHE_VERSION bumped 44 -> 45: this is parse-time capture emission, so a warm cache replays the pre-change capture set and the new edges never appear — observed directly, a full `analyze --force` produced a byte-identical graph until the cache was cleared by hand. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(javascript): pin A1/A5 plain-object property acceptance criteria Fixture plus todo specs for the four shapes plain-object property access has to answer: object-literal keys indexed as Property nodes, a read through the holding variable, a property WRITE, and a read through an untyped param. Records the investigation so the work is resumable: the parse-query pattern scoped to literals bound to a variable matches correctly (verified against the raw JAVASCRIPT_QUERIES), but no Property node reaches the graph and local-symbol-pruner is not the cause — it drops only Const/Variable/Static. The remaining gate is in the parse worker's node-creation path. No production code — specs only, so the suite stays green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(javascript): index object-literal keys of a named object as Property nodes Idiomatic JS models configuration as an object literal, not a class, but Property definition nodes existed only for DECLARED CLASS FIELDS. A config field therefore had no symbol at all: `context({name: 'exitMinAtrMult'})` answered "not found" for a field read and written throughout a live code path, and ACCESSES had no target to point at. Both halves are added for keys of a literal BOUND TO A VARIABLE — the parse query mints the graph node, the scope query mints the def the resolver can aim at. Unbound literals are deliberately excluded: an inline call argument or a JSX prop bag is call-site data, not a named surface other code references, so a node per key there would add volume without adding an answerable question. This lands the definition-node half only. The ACCESSES edges still require receiver resolution — typing the const that holds the literal to the literal's scope for the precise case, and name-based matching at reduced confidence for the untyped-param (option bag) case. Both are recorded as todos with the mechanism each needs. Also records a trap that cost a wrong conclusion: under vitest the parse worker runs the BUILT dist code (parse-impl resolves parse-worker.js, absent under src/, and falls back to dist), so parse-query changes are invisible to tests until `npm run build`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(cache): move the SCHEMA_BUMP pin to 45 The pin is the guard that makes two branches claiming one cache-schema number fail loudly instead of silently serving each other's entries, so a bump is only half-done until the pin moves with it. The bump itself landed with the JavaScript bare-identifier captures; this is the other half. Caught by the guard working exactly as designed — the suite failed with "expected 45 to be 44" rather than letting a mismatched pair through. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): resolve plain-object property access by unique name Idiomatic JS reads configuration off an object whose receiver cannot be typed — an options bag passed as a parameter, a destructured handle, an imported literal. No precise pass resolves those, so a field read and written across a live code path produced no ACCESSES edge at all and "who reads this setting?" answered a confident zero. A last-resort pass runs after every precise pass and sees only what they left behind. For each still-unresolved read/write site it asks whether exactly ONE Property in the workspace carries that name. If so the read almost certainly means it. If two or more do, nothing is emitted and the site is COUNTED as ambiguous — a guess between them would be a coin flip, and a wrong edge in the pre-edit safety gate is worse than a missing one. Uniqueness is the right gate because it recovers exactly the names worth recovering: distinctive domain fields (exitMinAtrMult, bookNotionalUsdt) are unique in a repo and resolve, while generic keys (id, name, data) are not and are skipped — which is where name matching would over-connect. Bounded four ways: - Confidence 0.5, the global tier, with the inference named in the reason, so a consumer can filter inferences without losing scope-resolved edges. - Never second-guesses a precise result: sites already resolved are excluded, because first-write-wins stops a duplicate but NOT a second edge to a different target. - Honors `fieldFallbackOnMethodLookup`. A statically-typed language opts out of name matching precisely because it over-connects; inferring an ACCESSES edge by name is the same claim and must obey the same opt-out. - Requires an explicit receiver — a bare identifier is not a property access, and matching one by name would link a local to an unrelated key. Indexes graph nodes rather than scope defs because an object-literal key mints a Property NODE but no scope-resolution DEF: `localDefs` and `scope.bindings` are both empty for exactly the population this serves. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(analyze): record a collapsed graph write instead of reporting fresh The dangerous half of a broken refresh: metadata IS written, so the index reads as fresh, hooks re-arm, and every tool answers from a graph missing most of its edges — indistinguishable from a codebase that genuinely has no such relationships. Reported in the field as edges collapsing 23009 -> 2170 and as a CodeRelation table that never materialized. `analyze` now compares the relationship count the pipeline PRODUCED against what the DB hands back after the write. Both numbers are already in scope at the same point, so the shortfall is provable rather than inferred — no comparison against the previous index, which cannot distinguish a failed write from a repo that legitimately shrank. A missing relation table needs no special case: it reads back as a persisted count of zero. On a collapse the run records `graphWriteCollapsed` in metadata, which `getIndexIncompleteReasons` turns into `graph-write-collapsed` so status and the MCP resources report the index INCOMPLETE rather than fresh. A ratio, not equality: some relationship types do not round-trip one-for-one and `--pdg` writes MORE rows into the same table, so demanding equality would fire on healthy runs. Only a collapse is a defect. Fail-safe when the expected count is unavailable — an implementation that offloads relationships out of memory may not be able to report a total, and a false "your index is broken" is worse than a missed one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(ingestion): qualify object-literal Property ids by their owning object Two config objects in one file that share a key name generated the same `Property:<file>:<key>` id and COLLAPSED INTO ONE node, so two distinct settings became a single symbol. Worse, the merged name then looked workspace-unique to name inference, which happily resolved reads of it to a node representing both — a wrong edge in the pre-edit safety gate, which is precisely what the unique-name pass is bounded to avoid. `objectLiteralOwnerInfo` already existed for exactly this ("so two constructors in one file that both define `bar` stay distinct nodes") but was gated to `Method`. `Property` now opts in. `findObjectLiteralBindingInfo` returns `ownerName` only when asked. Its `Method` ids must stay byte-identical — qualifying them would rewrite every object-literal method id in every indexed repo — while object-literal KEYS, indexed only since A1/A5, have no such history to preserve. Found by a test written for the ambiguity path rather than by review: the suite reported one node where two were expected, and an edge where none should exist. Both are now pinned, along with the detection boundaries of the B2 collapse check, which was previously an untestable inline expression and is now a pure function. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(typescript): index type aliases and shape members as symbols A TS frontend models its API contracts as `type X = { … }` and `interface`, so a field on one is exactly what "who breaks if I remove this?" is asked about. Three gaps made that unanswerable, all in the TypeScript queries: 1. No `type_alias_declaration` -> `@definition.type`, so an alias minted NO NODE AT ALL and a context() lookup on an exported contract type answered "Symbol not found". TypeScript was the ONLY language missing this — Rust (type_item), Kotlin (type_alias), Swift (typealias_declaration) and Dart all emit it. The alias was declared for scope resolution but never became a graph symbol. 2. No `property_signature` in the parse query, so INTERFACE members minted no Property nodes either — the upstream report's "class/interface index fine" holds only for the type, not its fields. 3. No `property_signature` in the scope query, so even with nodes present the resolver had no member declaration to aim at. Its sibling `method_signature` -> `@declaration.method` already existed; only properties were missing. Interface bodies and object-type aliases both spell members as property_signature, so one pattern per query covers both shapes. Lands the SYMBOLS, not yet the ACCESSES edges: the shape is already a class-like scope and now has member declarations, but no edge forms — the remaining link is owner/type-binding, recorded as todos with the diagnosis. Note TypeScript sets fieldFallbackOnMethodLookup:false, so unlike JavaScript there is deliberately no name-based fallback here; the precise path is the only route by design. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(golden): accept interface members in the mini-repo snapshot Drift is entirely the new TypeScript shape-member indexing: the fixture's three interfaces (ValidationResult 2, DbRecord 3, LogEntry 3) contribute exactly 8 Property nodes, each with exactly one HAS_PROPERTY owner edge. Verified before regenerating rather than after: every pre-existing count is untouched (CALLS 9, IMPORTS 12, DEFINES 16, HAS_METHOD 1, MEMBER_OF 12, STEP_IN_PROCESS 12), so nothing was rewired — the digest moved only because 8 edges were added. The fixture's inline `return { valid: false, … }` literals correctly produced nothing, confirming the object-literal rule stays scoped to variable-bound literals. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(analyze): never report a collapse from a non-numeric count The B2 check reported healthy runs as total graph-write collapses. A non-numeric `expected` (a graph implementation reporting no total, a lightweight pipeline result) does not skip the guards — it INVERTS them: `undefined < 100` is false, so the small-repo exemption never fires, and `0 >= undefined * 0.5` is `0 >= NaN`, also false, so the ratio check "passes" as well. Both bounds silently evaporate and every such run is flagged. That is precisely the failure this check was written to catch, reproduced inside the check itself: an unmeasurable quantity treated as a measured zero. Both sides are now validated as finite numbers before any comparison. `persisted` is also passed as UNKNOWN rather than zero when the DB was not demonstrably readable: `getLbugStats` flattens "no connection", "query threw" and "empty table" all into `edges: 0`, so `stats.nodes > 0` is used as independent evidence the read happened at all. Caught by the existing run-analyze suites, not by the new unit tests — those exercised the pure function with well-formed numbers and were blind to the integration's actual inputs. Both cases are now pinned. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(typescript): make object-type aliases own their members A TS object-type alias declares the same `property_signature` members as the interface beside it and answers the same question, but was not a member owner: its fields were minted with bare ids and no owner edge, so two aliases in one file sharing a field name collapsed onto one node, while the identical interface resolved normally. `type_alias_declaration` joins CLASS_CONTAINER_TYPES (and CONTAINER_TYPE_TO_LABEL, as that set's invariant requires — a container missing there gets orphaned member edges or a wrong owner label). Aliases with no object type (`type Id = string`) declare no members, so they own nothing and are unaffected. This also lands the INTERFACE field -> consumer edges, verified on the mini-repo fixture rather than only on a purpose-built one: `saveToDb` now links to `ValidationResult.value`, and `formatLogEntry` to `LogEntry.level` and `LogEntry.message` — three real contract-field reads that previously had no graph path at all. Golden updated: +3 ACCESSES, no node changes. The ALIAS field -> consumer edge is still not linked and is recorded as a todo with the exact blocker: resolving a receiver typed as the alias needs the NAME to resolve to a class-like def, and `isClassLike` is Class|Interface|Struct|Record|Enum|Trait. That predicate is read from ~12 sites including MRO and heritage, and every language mints TypeAlias, so widening it would enrol aliases in linearizations where they do not belong. Widening only the scope index was tried and reverted — the type-name walkers gate on it independently, so it fixed nothing and left dead code. That needs a deliberate "shape-like" concept, not more call-site widening. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(test): record the traced diagnosis for the unlinked alias field edge Traced to the end rather than left as "needs investigation", so the next attempt starts from facts: 1. Graph side is COMPLETE and symmetric with the interface — Property:...:LiveModeConfig.bookSlots is owner-qualified and carries HAS_PROPERTY. 2. Resolution DOES reach resolveClassBindingForName('LiveModeConfig') (instrumented) and misses. 3. It misses because the module scope binds LiveModeIface:Interface, renderAlias, renderIface — and not LiveModeConfig. The alias has no binding on the receiver's scope chain at all. 4. The TS scope query tags aliases @declaration.type, but normalizeNodeLabel accepts only typealias / type_alias and has no "type" case, so it returns undefined. Kotlin and Dart use @declaration.type_alias; TypeScript is alone on the dead tag. 5. Retagging is NECESSARY BUT NOT SUFFICIENT — tried, and the binding still does not appear, so a second gate exists in how a declaration anchored on a node that is ALSO a @scope.class anchor is attached: the alias appears to bind inside its own scope rather than hoisting to Module, where interface_declaration evidently does hoist. An isShapeLike predicate (the nominal-vs-structural split: shapes declare members, nominal types participate in MRO) plus a mirrored findShapeBindingInScope were built and REVERTED along with the retag. With no binding on the chain they never fire, and shipping inert widening is worse than shipping none — the same standard applied to the earlier scope-index attempt. The design is recorded here; it is worth doing once step 5 is fixed, and it also unblocks Rust's parked union_item, which the MEMBER_OWNER_NODE_TYPES comment documents as the same gap in another language. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): resolve cross-file value references, skip block-locals Two halves of the same question, "who uses this constant?". CROSS-FILE. `resolveReferenceSites` runs against the registries and, as its own comment says, "imports live in finalized bindings the registries can't see" — which is why free CALLS need `emitFreeCallFallback`. Reads had no counterpart, so `import { LIMIT }` followed by a bare use resolved to nothing while a CALL through the very same import statement resolved fine. This adds the read/write counterpart, reusing `findValueBindingInScope` (which walks the FINALIZED chain) rather than inventing a lookup. Confidence 0.9: the import names the def, so this is precise resolution, not inference. BLOCK-LOCALS. Bare-identifier capture also matches a read of a block-local `const`, and an edge to one keeps alive exactly the inert locals `pruneLocalSymbols` exists to drop — a pruned node becomes a retained node plus an edge, in every function of every indexed repo. Emission now takes the set of value defs bound at MODULE scope and drops ACCESSES to Const/Variable/Static outside it. The cross-file pass carries the same guarantee structurally: a def in another file cannot be a block-local of this one, so it skips same-file hits entirely. The block-local leak was already shipped in the intra-file A2 commit and was found only because a test was written for the guard rather than the feature — the same way the object-literal id collision surfaced. Verified on the full resolver matrix: 3172 tests, golden unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(lbug): diagnose a vanished staging CSV instead of surfacing a Binder error A forced rebuild could fail with "COPY failed for File: Binder exception: No file found that matches the pattern .gitnexus/csv/file.csv" and then an ENOENT on .gitnexus/csv/rel_Folder_File.csv — two engine-level messages that name neither a cause nor a remedy, which is where several field reports end. Only tables with rows > 0 enter the COPY manifest (csv-generator.ts), so an absent file was WRITTEN during this run and removed since. Both COPY loops now preflight and say exactly that, with the row count, both causes the reports point at (a second `gitnexus analyze` on the same repo — they share .gitnexus/csv — or an external cleanup of .gitnexus/), and the action to take. Scope note, deliberately narrow: this does not attempt to fix WAL corruption or checkpoint rotation. Those already have detection and recovery hints (isWalCorruptionError, WAL_RECOVERY_SUGGESTION, the configurable wal-checkpoint-threshold), and the ~6000 lines added to lbug/ + storage/ since v1.6.9 — index-lock.ts most of all, which serializes writers and plausibly closes the concurrent-run class outright — postdate every report in the window. Guessing at unreproducible durability faults would be speculation; making the one failure with NO handling legible is not. An existing overlap test induced this exact scenario (a manifest entry pointing at a missing csv) and asserted on the engine's wording. Its intent — that a node-COPY failure is rethrown at the FK barrier rather than swallowed — is unchanged and still asserted; only the message it matches moved. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): split shape-like from class-like, linking alias fields Completes A4: a field on a TypeScript object-type alias now links to the code that reads it, the last unanswerable half of "who breaks if I remove this?" for a TS frontend that models contracts as `type X = { … }`. `isClassLike` answered two questions that only coincide for classes: 1. does this declare MEMBERS I can look up? — a SHAPE (structural) 2. does this participate in inheritance / MRO? — a NOMINAL TYPE An object-type alias is (1) and emphatically not (2) — it has no supertypes and no place in a linearization. Widening `isClassLike` to buy (1) would have enrolled every language's aliases (Rust type_item, Kotlin/Swift/Dart typealias, C typedef) into MRO and heritage, so the two questions now get two predicates. Call sites split by which they ask, and their names already said which: `resolveInheritanceBaseInScope` and `resolveQualifiedInheritanceBase` keep `isClassLike`; receiver typing and member OWNERSHIP take `isShapeLike`. Three parts, each necessary and none sufficient alone: - `findShapeBindingInScope`, mirroring `findValueBindingInScope`'s established relationship to `findClassBindingInScope` (same walker, different accepted def-type), consulted only AFTER the class lookup misses so a class of the same name always wins. - `populateClassOwnedMembers` uses it, so alias members get an `ownerId` and are registered under the alias. Without this the receiver resolved to the alias and then found no members under it. - The TS scope query tags aliases `@declaration.type_alias`, not `@declaration.type`: `normalizeNodeLabel` accepts typealias / type_alias and has no "type" case, so the old tag mapped to NO label and TypeScript aliases produced no scope-resolution def at all. Kotlin and Dart already spelled it this way; TypeScript alone was on the dead tag. An earlier attempt concluded a further "scope-attachment gate" existed. That was wrong and is worth recording: scope extraction runs in the parse WORKER, which loads built `dist`, so the retag was never executed. Rebuilt, the alias hoists to Module scope exactly as the interface does. Same trap as the parse query — `src` edits to anything the worker runs are invisible until `npm run build`. Typedef and Union stay out of `isShapeLike` deliberately: they belong conceptually (the union_item note on MEMBER_OWNER_NODE_TYPES records the same gap) but neither is wired as a member container, so including them would widen a predicate nothing exercises. Verified on the full resolver matrix: 3173 tests, golden unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(typescript): pin the type-alias capture to a tag that maps to a label The capture test asserted `@declaration.type`, the tag that `normalizeNodeLabel` does not recognize (it accepts typealias / type_alias and has no "type" case). So the test passed for as long as the tag was broken: it checked only that the capture FIRED, never that it resolved to anything, while TypeScript aliases produced no scope-resolution def at all. Updated to the working tag and given a second assertion that the derived kind string is one the label mapper accepts — the property that actually matters, and the one whose absence let a dead tag sit pinned. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(lbug): declare TypeAlias member pairs so analyze does not abort Making object-type aliases member owners emits HAS_PROPERTY from a `TypeAlias`, and the relation schema declared no such pair. The emit therefore threw `UndeclaredRelationPairError` and the ENTIRE analyze died on any repo containing `type X = { ... }` — a hard stop, not a dropped edge. Found by running the analyzer over a real 16k-node TypeScript repo, not by a test. `Method` is declared alongside `Property`: a member written `type Handler = { onClick(): void }` is a method_signature and would fail in exactly the same way. Why every existing test missed it: the resolver suites build an in-memory graph via `runPipelineFromRepo` and never write to LadybugDB, so the schema constraint was never exercised. `structural-pair-coverage.test.ts` is the one suite that does run the emitters against the declared pairs — and its own docstring names the gap: coverage is bounded by NON_BRIDGE_CORPUS, "a new structural emitter should land with an entry here". This adds that entry, pinning TypeAlias|Property and Interface|Property as sentinels. Verified the guard is not vacuous: removing the pair again makes the suite fail with undeclaredPairs: ["TypeAlias|Property"]. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(processes): trace depth-first so multi-hop flows are detected D1 ("query ranks frontend components above the backend module that owns the concept") and D2 ("processes is dominated by trivial mechanical chains") are the same defect, and neither is about ranking or selection. The walk stops after a fixed NUMBER of traces, so traversal order decides which traces those are. Breadth-first reaches every shallow terminal before any deep one, so the quota filled with the shortest paths in the graph and the walk stopped — `maxTraceDepth: 10` was never approached. Measured on a real repo before the fix: of 300 processes NONE exceeded 7 steps and 90% were 3-4. A multi-hop business flow (signal → order → exit) therefore had no process that could represent it, and `query` could only rank the mechanical pairs that did exist. Step 4 of the caller already sorts by length and dedupes by endpoint — it was always asking for the deepest traces this walk could give it. Depth-first descends to a terminal first, so the same quota is spent on paths worth keeping. Cost is unchanged: same budget, same cycle guard, same depth ceiling — only the order differs. Measured on the same 16k-node repo, same build and flags, BFS vs DFS (an earlier comparison was discarded as confounded — it crossed builds and --pdg): steps 6-8: 50 → 168 (3.4x) totals: 844 → 806 and the reported query moved from `LiveSetupView → Cn` (a React component) to `ReconcilePositions → IsTpInProfit / WithHeld / ShouldNotify` — server-side exit management, which is what was asked for. `traceFromEntryPoint` is exported for the test. Traversal order is unobservable through `processProcesses`: `findEntryPoints` supplies several starting points, so a deep chain is traced from inside it whatever the order does. A test at that level passes under BOTH traversals — the first version of this test did exactly that and guarded nothing. Driving the walk directly, it fails under breadth-first with "expected 3 to be greater than 3". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(test): correct a stale status note left behind by a later fix The A1/A5 header still said "edge resolution REMAINING ... neither is implemented". Both shapes resolve — the typeable receiver precisely, the untyped one by workspace-unique name — and the tests below assert exactly that, so the note contradicted the file it sat on. It was accurate when written and went stale when the work continued past it. Left as-is it would tell a reviewer that a landed feature is missing. The TRAP note is kept: the parse worker still runs built dist under vitest, and that is still the trap it describes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): index literals behind identity-preserving wrappers `export const INERT_EXIT_CONTRACT = Object.freeze({ ... })` minted no `Property` node for any of its keys. The object-literal rule matches `variable_declarator > value: (object)` as a DIRECT child, and freezing puts a call expression in between — so the shape whose fields are most worth querying was the one shape the rule could not see. Freezing a config object is how JS publishes an immutable contract, which is why this reads as a confident zero on exactly the fields a reader cares about. The allowlist is three functions, not "any call". `Object.freeze`, `seal` and `preventExtensions` RETURN THE ARGUMENT THEY WERE GIVEN, which is what makes the literal's keys members of the bound name. For `const x = compute({ a: 1 })` the literal is an argument and `x` holds compute's return value, so attributing `a` to `x` would be a fabrication. Two negative controls, because the obvious one is vacuous: a bare-identifier callee is rejected structurally and would pass with no allowlist at all, so the assertion that actually pins the predicate uses `Object.entries` — identical shape, differing only by name. Verified load-bearing by adding `entries` to the allowlist and watching that test alone fail. SCHEMA_BUMP 46 -> 47: parse-time emission, so a warm cache replays the pre-fix capture set. Observed as a false negative first — `analyze --force` returned the old node set until the on-disk cache was removed by hand. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): narrow multi-candidate property names by scope Workspace uniqueness was the wrong denominator. Measured on the reporting repo: `exitMinAtrMult` has 26 `Property` definitions — 16 in one-off `scripts/`, 7 in the frontend, one in a test, and exactly ONE in the backend that reads it. Every backend read was refused because of competitors the reader cannot see. The gate was not too permissive or too strict, it was scope-blind. A name with several definitions is now narrowed before being abandoned: same-file first, then files the reading file directly imports, using the finalized import graph rather than a path-shape heuristic. Exactly one survivor at the first non-empty tier resolves; anything else stays refused. A tier holding several candidates stops the walk instead of falling through — local evidence that is itself ambiguous still contradicts reaching further out. Confidence stays 0.5 at every tier. Narrowing changes which candidate is chosen, not the kind of claim: it is still a name match, and the round-1 contract is that filtering on confidence drops all name inference at once. The reason string now names the tier that fired. Ambiguity reporting goes from a count to the actual names (capped), because a count says a gap exists while the names say which fields are unanswerable. Measured on that repo, backend readers of `exitMinAtrMult` go 0 -> 24 and total readers 9 -> 45, including the two call sites in `oppositeSignalExitManager.js` the report singled out. Both narrowing tests were mutation-checked by dropping the import evidence and confirming they, and only they, fail. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): capture destructured parameter keys as property reads `function exit({ exitMinAtrMult = 0 })` reads that property off whatever the caller passes, exactly as `cfg.exitMinAtrMult` would. It never appears in a member_expression, so it had no reference site at all — and this is the shape the function that IMPLEMENTS a behaviour uses, so the most relevant reader was the one systematically missing from "who reads this setting?". Uses a distinct `@reference.read.destructured` anchor rather than `@reference.read.member`. The latter is filtered emit-side to matches with a member_expression ancestor, because calls and writes share its shape, and a destructuring pattern has none — reusing the tag would have been silently dropped by that filter. The `read.` head already maps to a read kind, so no mapping change is needed. Scoped to formal_parameters. A destructuring binding elsewhere (`const { x } = require('m')`) is frequently an import rather than a field read, and minting a property read there would attribute module bindings to unrelated same-named keys. All three cases (default value, bare shorthand, renamed key) mutation-checked by removing the patterns and confirming those three tests, and only those, fail. The renamed case also asserts the edge points at the KEY and that the local alias mints nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): link type consumers to the type they name An exported contract type owned its members after round 1 and still answered `incoming: {}`, so "what breaks if I remove this field?" — the question a contract type exists to answer — had no edge to walk. Measured on the reporting repo: all 324 TypeAlias nodes AND every Interface node had DEFINES as their only incoming edge. Two independent causes, and the second is why the first was not enough. TypeScript captured no type references at all — only cpp and csharp did — so an annotation naming a declared type minted no reference site. Added for annotations, generic arguments and `as` assertions, anchored to those contexts rather than a bare `(type_identifier)`, which would also match the name in `type X = …` and make every declaration a consumer of itself. That alone fixed interfaces and left aliases still empty. `TypeAlias` was missing from `LINKABLE_LABELS`, so alias graph nodes were never indexed in `nodeLookup` and `resolveDefGraphId` could not bridge a def to its node — the edge was dropped AFTER a successful lookup. `CLASS_KINDS` has always listed TypeAlias and the ClassRegistry returned the def correctly, which is what made this read as a resolution failure; instrumenting the lookup showed it returning the right def all along and moved the search one table over. Exactly the bug already documented two entries above it for Trait. Fixes every language that spells an alias this way — TypeScript, Kotlin, Dart and Rust all emit `@declaration.type_alias`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): capture record construction as property writes The read side answered well after the narrowing work while "who SETS this field?" still missed the code that stamps the value. A record built inline — `return { exitContract: { exitMinAtrMult: settings.x } }` — is bound to no variable, so it minted no definition and its keys referenced nothing. Modelled as WRITE REFERENCES, deliberately not definitions. The round-1 rule already mints Property nodes for literals bound to a variable; minting more for anonymous records would add same-named competitors to the very name-narrowing that makes these fields resolvable — measured at 26 competing definitions for one field on the reporting repo, which is what made every backend read unanswerable in the first place. A construction site is a USE of a field, not another declaration of it. Two positions only: nested under a key, and returned. Both are records with a name attached (the key, or the function). An inline call argument (`doThing({ id: 1 })`) stays excluded for the same reason round 1 excluded it from definitions — it is call-site data, not a named surface — and is asserted as such. The enclosing literal is the receiver and it is anonymous, so these route through the same narrowing and the same refusal-to-guess as every other untyped receiver. Verified on the reporting repo: `entryPlan.js` went from no rows to `selectExitEnvelope` as a writer of `exitMinAtrMult`. Both captures mutation-checked. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(processes): select round-robin by terminal so the list is not one flow repeated Ranking was `sort by length` alone, so the top of the list was one behaviour described many ways: eleven of the top fourteen processes on the reporting repo were four entry points crossed with three terminals of the SAME date-window utility cluster. Genuine call chains, but a reader learns one thing from fourteen entries, and the repo's own domain flows sat below them. Selection now round-robins across TERMINALS, deepest first. Depth still orders within a terminal and still leads the list; what changes is that no terminal takes a second slot until every other has had a first. Keying on the entry point was tried first and made it worse — many files declare a `main`, so each was a distinct entry that round-robin then awarded its own slot, and `Main -> AlignWindowEnd` went from one row to eight. The repetition was never in where a flow starts. Measured on that repo: distinct terminals in the top 20 went 3 -> 20, and its domain flows (`ReconcilePositions -> ...`) moved into the top 4%. Two things this deliberately does not claim. The reported cause — ranking rewarding fan-in, promoting chains ending in widely-called helpers — measured FALSE: those terminals have one caller each (`alignWindowStart` 1, `validateSymbol` 1). A fan-in discount was implemented against that hypothesis, measured, and reverted for moving nothing. And a business flow still cannot be a process in its own right: the walk only emits at a leaf, at max depth, or on a cycle, so a flow whose meaningful endpoint calls onward survives only as whatever leaf it bottoms out in. Both are recorded in the code so neither reads as settled. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(structural-pairs): pin the type-annotation USES pair R2-2 emits USES INTO a `TypeAlias`, so the pair is `Function|TypeAlias` — a different table from the `TypeAlias|Property` entry added in round 1, and one that entry stays green without. `TypeAlias` is on the eleven-table list this suite exists for, and an undeclared pair does not degrade: it throws `UndeclaredRelationPairError` and kills the entire analyze on any repo containing an annotated type. Every resolver suite still passes, because they build an in-memory graph and never write to the DB. That exact failure shipped once in this PR already. Two emitters into the same label, each with its own way to reach a released build. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): build the module-level set before the out-of-core seal Review blocker. Under `GITNEXUS_DISK_SCOPE_INDEX=1` the seal replaces every ParsedFile with a scope-STRIPPED copy, and the block-local filter's set was built after it — so it walked `scopes: []` for every file, came out empty, and the filter read that as "no def is module-level" and dropped EVERY `Const`/`Variable`/`Static` ACCESSES edge in the repo. All languages, all files, including the module-scope-const edges this PR exists to add. Nothing threw and nothing logged, on the path the largest repos take: the exact confident-empty answer the PR is about. Built above the seal now, from `parsedFiles`, and passed as `undefined` rather than an empty set when no scope was inspectable — an empty set is a legitimate answer ("this repo has no module-level value defs") and must not be indistinguishable from "could not look". Fails open; the block-local exclusion is still asserted under the seal, since that is correctness rather than optimization. Also widens module level past `kind === 'Module'`. A `Namespace` scope (TS `namespace`, Rust `mod`, C++/C# `namespace`) holds importable values too, and treating its consts as function-locals dropped their reads. Included only when the whole chain to the root is Module/Namespace, so a namespace declared inside a function body stays local — asserted both ways. That fixture then failed for a third reason: `@reference.read.identifier` existed ONLY in the JavaScript query, so A2 did not work for TypeScript at all. Added there, and both languages widened to `variable_declarator value:` and `binary_expression` operands — the gaps review named between what A2 claimed and what it matched. Nothing covered `GITNEXUS_DISK_SCOPE_INDEX`. The new parity test asserts the seal changes no edge, and was verified against an emulation of the original bug: same-file readers vanish and only the cross-file reader survives. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(typescript): anchor property_signature to declared shapes Review blocker, and it reproduces end to end. `property_signature` occurs in EVERY object_type in the TS grammar, not only in an interface body or an alias's object type, so inline parameter types, inline return types and nested object types all matched — and the enclosing-container walk hung each one off the nearest class, interface or alias. Measured against the unanchored rule, all four appeared as members of shapes that do not have them: Property:contracts.ts:Svc.inlineParamOnlyKey Property:contracts.ts:Repo.inlineQueryOnlyKey Property:contracts.ts:NestedConfig.nestedOnlyKey Property:contracts.ts:buildInline.inlineReturnOnlyKey@46:33 When the inline member shares a name with a real one — `run(opts: { retries: number })` inside a class that declares `retries` — `addNode` is first-write-wins and the two distinct symbols merge onto one node, so every context()/impact()/rename() answer about that field describes the merge. The sibling JS object-literal rule in this same PR is anchored for exactly this reason; this is the TypeScript half of the same fix. `(A (B))` matches DIRECT children, so nested object types are excluded by the same anchor rather than by a second rule. The first version of these tests was VACUOUS and is recorded here because the reason generalizes: a collision and a correct exclusion both leave exactly one node behind, so counting ids cannot distinguish them. Every inline member in the fixture is now uniquely named, which is the only thing that discriminates — verified by restoring the unanchored rule and watching exactly those four assertions fail. A fifth test asserts anchoring costs no real member. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(analyze): correct the numbers feeding the graph-write-collapse guard Review blocker. The predicate itself held under adversarial probing; every defect was in what it was handed and what happened after it fired. (a) `expected` was wrong twice. Under `GraphEmitSink` streaming the bulk types leave the heap at parse time and never enter `relationshipCount`, so the count understated the real volume by most of it and the ratio passed trivially — on `force === true` runs, which include crash recovery AND the `analyze --force` retry this check's own warning tells the operator to run. Adds the manifest totals, the same correction the buffer-pool hint in this file already makes for the same reason. Separately, an incremental run persists only the changed subgraph while both counts are whole-scope: a 10,000-edge index that lost 200 replacements reads 9,800 and is certified complete. The check is skipped on that path rather than answered wrongly. (b) A throwing edge count became a measured zero. `getLbugStats` initialised its total to 0 and ran the query in a swallowing catch, so WAL/lock contention during finalize — documented on this exact call — reported a healthy index as a total collapse. It now returns `number | undefined`, and the caller requires both a readable node count and a defined edge count. (c) A total loss was exempted for being small. The min-edges rule tested `expected` before looking at `persisted` at all, so `expected = 99, persisted = 0` — every edge gone — stayed fresh and reported success. Total loss is now decided first. The existing test asserted the defect; it now asserts a PARTIAL shortfall, which is the case the exemption was written for. (d) A detected collapse reported success and exited 0. It is different in kind from the other incomplete reasons: those describe a run that did what it said and left work for later, this one means most of your edges are gone and every query answers a confident empty. The CLI now prints INCOMPLETE with the counts and sets a non-zero exit code, and the flag crosses IPC so the worker cannot send a clean `complete` either. Nothing exercised this wiring — only the pure helper. Adds tests for all four, each written so the pre-fix arithmetic fails it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): keep unique-name property inference inside one language The pass indexed `Property` nodes from the whole shared graph. Per-language gating decides whether it RUNS for a language; it never restricted which nodes could be TARGETS. So the only carrier of a name could be in another language entirely, and a read here resolved to it on name uniqueness alone — no owner, no file, no call path. Reproduced: a Java class declaring `private int loyaltyPointsBalance` and a JS `cfg.loyaltyPointsBalance` on an untyped parameter produced an ACCESSES edge from the JS function to the Java private field. Confidence does not mitigate it, because `minConfidence` defaults to 0 — the tier is only a filter for consumers who ask for one. Candidates are now restricted to files in the language's own `parsedFiles`, which is a precise restriction rather than a heuristic and needs no new node property. Every other fixture in the suite is single-language, so this could not be caught anywhere by construction. The new fixture is deliberately polyglot and asserts both halves: no cross-language edge, and a same-language unique name still resolves. Known and not addressed here: the index is still O(total graph nodes) and is rebuilt once per qualifying language, the per-language whole-graph-scan pattern `phase.ts` hoisted out for `sharedNodeLookup`. Hoisting it belongs with that machinery rather than in this fix. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(processes): explore siblings in source order, log the exhausted budget `slice(0, maxBranching)` selected the FIRST N callees while `pop()` explored them LAST-first, so the trace budget went to the last-declared branch. For `main() { init(); loadConfig(); run(); shutdown(); }` the walk spends itself on `shutdown` and can drop `init` — the earliest steps of a flow, which is the opposite of what a process describes. Selecting first-N and exploring last-first was simply inconsistent; pushing in reverse makes the stack pop in source order. Measured on the reporting repo, this costs depth: 6-8 step processes go 168 -> 146 of 816. Still roughly three times the pre-PR baseline of 50, and the right trade — a deep branch is no longer reached by accident of being declared last. The remaining limit is the BUDGET, not the traversal: with a fixed quota a deep branch declared after enough shallow ones is not reached at all. That is now asserted in both directions rather than left implicit, and the walk logs when it stops with branches unexplored — a silently truncating cap reads as "this is everything", the same confident-empty answer this work is about, and the repo already sets that precedent for `dispatchFanoutSkipped`. Removes the second depth test, which was vacuous: the note twelve lines above it already said a `processProcesses`-level depth assertion passes under BOTH traversals, and measured it does — breadth-first yields the same deepest stepCount of 8, so it passed with the production change reverted. Traversal order is asserted against `traceFromEntryPoint` directly; what is observable at the pipeline level is which traces survive selection, which the diversity tests cover. Also renames `queue` to `stack` and corrects the BFS references in the module docstring and the function's own JSDoc, which is what an IDE hover shows. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(impact): carry riskNote onto ambiguous candidates and separate UNKNOWN's two meanings Two problems on the ambiguous fan-out, which builds its own candidate object rather than returning the single-symbol shape. The narrowed type had no `riskNote` field and never read one, so a candidate that resolved and found no callers reported `risk: UNKNOWN` with nothing attached — losing the entire point of the change on the path where the reader has the least context, since the name is ambiguous there by definition. And `UNKNOWN` used to mean exactly one thing on this path: the probe threw. The zero-caller branch gives it a second meaning, so an all-UNKNOWN fan-out could no longer be told apart from a broken one. Candidates now carry `probeFailed`, and the comment asserting the old reading is corrected. Also aligns `gitnexus-web`, which review flagged as giving a different verdict for the same symbol. That surface answers in prose rather than an enum, and its message said the symbol "appears to be unused (not called by anything)" — the identical false certainty in words. It now carries the same MEANING rather than the same field. Downstream wording is unchanged: no outgoing dependencies really is a fact about the symbol itself. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test: replace assertions that cannot fail Four from review, each satisfied by the defect it was meant to catch. `new Set(props).size === 2` over two different literal strings can only ever be 2, so it could not detect the node merge its title promises — that is a difference in COUNT, now asserted on the raw array. The ambiguity test asserted only an empty edge set, which is satisfied equally by "the gate fired" and "the name was never looked up". It now also requires the ambiguity counter to have moved. `Interface|Property` was listed as a structural-pair sentinel beside `TypeAlias|Property`, but both its labels are in the SCOPE_BRIDGE cross-product so the pair is generated by construction and the sentinel cannot fail. Dropped rather than left reading as coverage; `TypeAlias|Property` is the load-bearing one. `TypeAlias|Method` was declared in the schema with no fixture emitting it — a declared pair no emitter exercises is indistinguishable from a missing one until an analyze aborts on a real repo. Adds a method-shaped alias member, and the suite requires sentinels to actually appear, so it is not vacuous. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs: document the new incomplete reason, the UNKNOWN verdict and the id churn Review found the code changes landed without the guidance around them, and an agent following this repo's own rules would have been told the wrong thing. `graph-write-collapsed` joined `INDEX_INCOMPLETE_REASONS` with no Sign block and no recovery section, while the precedent it cites (`embedding-checkpoint-pending`) has both — so `gitnexus status` would surface a new string naming silent wrong answers with nothing explaining trigger or remedy. Added to RUNBOOK and GUARDRAILS, including why this reason alone also fails the exit code. `AGENTS.md` said MUST warn on HIGH or CRITICAL and never mentioned UNKNOWN, and the shipped impact skill's risk table had no UNKNOWN row and still implied few-callers ⇒ LOW. An agent obeying those rules literally sees `risk: UNKNOWN` and proceeds, which negates the change the verdict exists to make. Both copies of both skills updated. `MIGRATION.md` now records that process ids do not survive this release — positional ids plus depth-first tracing, source-order siblings and round-robin selection mean `proc_7_handle` is a different flow afterwards. Bounded honestly: nothing in-repo joins on a raw process id, so it is index churn, not a broken consumer. `ARCHITECTURE.md`'s scope-resolution stage list gains the two new stages. The guide skill's node list gains `Property` and `TypeAlias` — the two node types this work most prominently creates. Also, on the pair-CSV preflight review asked to confirm: the hard abort IS deliberate, because a fallback recovering zero rows is the confident-empty failure this work targets. But the transient the message itself names — a second concurrent analyze sharing `.gitnexus/csv` — is a race, so the check now re-looks three times over ~150ms before declaring the file gone. Long enough to ride out a rename, far too short to mask a file that is genuinely missing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix: drop redundant TypeAlias pairs and keep bare identifiers off class members Two regressions the full suite caught after the review fixes, both real. `schema-pair-coverage` failed with eleven hand-declared pairs that a rule now generates. Adding `TypeAlias` to `LINKABLE_LABELS` — needed so `resolveDefGraphId` can bridge an alias def to its node — also makes it a SCOPE_BRIDGE source and target, so the cross-product produces `File|TypeAlias`, `TypeAlias|Property` and nine others that round 1 had declared by hand. Removed; the invariant is that no pair is both generated and hand-declared. This also changes what the structural-pair sentinel means, and the comment is corrected rather than left overstating it: `TypeAlias|Property` is no longer load-bearing because the label is off the generated grid — it is load-bearing because it now depends on `TypeAlias` being IN `LINKABLE_LABELS`. Remove it and the pair stops being generated while the hand declaration is gone, which is the same state that silently breaks alias consumer edges. `block-scope-shadowing` failed because a bare identifier resolved to a class `Property`. `class Box { baseUrl = '...'; pick() { const baseUrl = ...; return baseUrl; } }` linked the block-local read to `Box.baseUrl`, duplicating the legitimate `this.baseUrl` edge. A bare identifier is not a member access: with no receiver there is no object whose property it could be, and in JS/TS a field read needs `this.`. Receiver-less read/write sites no longer accept `Property` hits; callables stay reachable, so `cb = save` naming a top-level function is unaffected. That defect PREDATES this branch's TypeScript captures — JavaScript has emitted bare-identifier reads since A2 and no class fixture exercised the shadow. The TS parity added here is what surfaced it. Golden snapshot regenerated after verifying the drift line by line: exactly +5 USES from type annotations in the mini-repo, every pre-existing count unchanged, so nothing was rewired. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * perf(scope-resolution): share the property-name index across language passes Review follow-up. `indexPropertyNodesByName` scanned every node in the graph and was rebuilt inside each qualifying language pass, reintroducing exactly the pattern `phase.ts` hoisted out for `sharedNodeLookup` — whose comment records why it matters: "the previous per-language rebuild burned that CPU+heap N times and, on a huge repo, a tiny language's full-graph copy overlapped the next language's — a real contributor to the scope-resolution memory peak." Built once in `phase.ts` beside `sharedNodeLookup` and `sharedFnNodeIndex`, and threaded through the same `prebuilt*` seam, so tests and isolated calls still build their own. Sharing is only safe because the per-language restriction MOVED rather than disappeared: the shared index is whole-graph, and candidates are filtered to the language's own files at lookup time. That also fixes a subtlety the per-language build had backwards — the cap now applies to the FILTERED set, so a name carried by forty properties across a polyglot monorepo but only two in the language being resolved is still answerable, where a global cap would have refused it. The tri-state at the lookup boundary is deliberate and the three outcomes are not interchangeable: no property of this name in this language (nothing to say, and NOT an ambiguity), too many to choose between (reportable), or a list to narrow. Caught mid-change by the polyglot fixture: an intermediate state shared the index without moving the filter, and the cross-language edge came straight back. That test earning its keep twice is the reason it exists. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): report when a field's only anchor is another language Round 3, found OUT-OF-SAMPLE — six field names appearing in no prior report, so nothing here was tuned against them. All six answered 0 backend ACCESSES while their definitions sat in `apps/research-dashboard/**`: TypeScript only. The in-sample set scored 5/5 and the out-of-sample set 0/6, and the gap is entirely this. Per-language inference (`3c5eadc7`) is right and stays. What was wrong is that declining is INVISIBLE: an empty result for a field anchored only in TypeScript is byte-identical to an empty result for a field nobody reads. One says "look in the other language or grep"; the other says "delete it". That is the same confident-empty failure this series exists to remove, one surface over — and this time the missing fact is about the ANALYZER's reach rather than the code. Declines are now counted and named, with the languages the anchors actually live in, kept SEPARATE from ambiguity because the remedies differ: ambiguity wants better receiver typing, this wants an anchor in the reading language. Collapsing them would tell a reader the wrong thing to do. A non-zero count warns at analyze time regardless of dev mode. The facts are published as `PipelineResult.propertyInference`, which they had to be for any of this to be testable — and that exposed a second defect. The round-2 ambiguity assertion, which I told the reviewer of #2856 I had strengthened, read its stat off a `scopeResolution` field that does not exist on PipelineResult: the `if (undefined) return` guard swallowed it and the test passed with the production code deleted. Both that assertion and the new ones now read the published field, and the guard is an assertion rather than an escape. Verified by deleting the counter and watching them fail. Reported by the same round-3 method note that caught it: verifying a fix against the cases it was written for only proves those cases pass. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(context): explain an empty property result caused by a cross-language anchor The other half of R3-1. The analyze pass now knows which fields it declined to link because every definition of the name lives in another language; this puts that fact where it is actually read. `context()` on such a field previously returned an incoming list byte-identical to a genuinely unread field. The two demand opposite actions — "look in the other language, or grep" versus "delete it" — so the difference has to travel with the answer: unresolved: property reads of this name were NOT linked: every definition of it is typescript, and name inference does not cross languages. An empty or short incoming list here is not evidence the field is unused — confirm with a text search, or give it an anchor in the reading language. anchorLanguages: ['typescript'] Carried through repo meta because the graph cannot answer it: the unlinked reads mint no edge and no node, so the only record is the pass that declined them. Keyed on the NAME, not on the resolved label. Gating on `=== 'Property'` was tried first and is wrong — the label reads `''` on this path for a plain Property node, so the gate silently suppressed the entire feature while every test still passed. Caught by asserting the field is DEFINED rather than guarding on it, which is the same anti-pattern that made two earlier assertions vacuous. The meta list only ever contains property names, so matching the name is itself the type check. Cached per (index, indexedAt): `ensureInitialized` deliberately avoids a per-call `loadMeta` because every tool routes through it, so this re-reads exactly when a re-analyze could have changed the answer and never otherwise. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): report declined property reads for opt-out languages too Generalizing R3-1 rather than waiting for it to be re-reported in the other direction. The reported case was a JavaScript read whose only anchor was TypeScript; the mirror — a TypeScript read anchored only in JavaScript — was still silent, because a language that sets `fieldFallbackOnMethodLookup: false` had the whole pass skipped, and skipping emission also skipped REPORTING. Detection is not inference. Counting what could not be linked asserts nothing about what it means, so `reportOnly` runs the pass for its facts while emitting no edge, and the opt-out keeps protecting exactly what it protected before. Two things this turned up that a single-instance fix would have missed: The cross-language fixture could NOT prove `reportOnly` is load-bearing — the per-language candidate filter already blocks those edges, so the assertion passed with the flag forced off. The case that discriminates is a SAME-language TypeScript read that name inference could legitimately link and the opt-out forbids; forcing the flag off there emits `readsTsOnly -> tsOnlyBudget`, which is the violation. Getting to that case surfaced a sibling gap, recorded but NOT fixed here: the object-literal `Property` rule is JavaScript-only, so `const CONFIG = { ... }` in a `.ts` file mints no node and its keys are invisible. The first draft of this fixture used exactly that shape and could not discriminate for that reason. It is the TypeScript half of R2-1a and wants its own change, not a rider on this one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(typescript): index object-literal keys, as JavaScript already did The sibling recorded in `0c5a4f64` and deliberately left out of it. Both the named object-literal rule (A1/A5) and the identity-wrapper rule (R2-1a) lived only in JAVASCRIPT_QUERIES, so the single most common config idiom in TypeScript — export const tsRuntimeConfig = { tsConfigRetries: 3 }; — minted no node for any key. `context()` answered "Symbol not found" and a precise read through the holding variable had nothing to resolve to. TypeScript sets `fieldFallbackOnMethodLookup: false`, so these gain no name-based inference. What they gain is the PRECISE path, which is the route TypeScript is meant to use: `tsRuntimeConfig.tsConfigRetries` has a typeable receiver and now resolves. A read through an untyped receiver stays unresolved and, since `0c5a4f64`, is reported as such rather than answering an empty set. Scoped exactly as the JavaScript rules are — bound to a variable, and for the wrapper only the three functions that return the argument they were given — with the same `Object.entries` negative control pinning the allowlist. Found by fixture, not by report: the first draft of the `reportOnly` test used a TS `const CONFIG = { ... }` as its discriminator and could not discriminate, because the shape mints nothing. That is the whole argument for sweeping a class instead of waiting for each instance to be filed. SCHEMA_BUMP 47 -> 48: parse-time, so a warm cache replays ParsedFiles carrying none of these matches and the keys stay invisible. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): anchor anonymous returned object literals to their function The last gap round 3 named, and the dominant shape in idiomatic JS: 437 `return {` sites in a single backend directory of the reporting repo, including the ~25-field payload of its entire signal pipeline. The literal binds to nothing, so its keys could not even be named — "who reads wickRatio?" had no symbol to ask about. The enclosing FUNCTION is the owner: the literal is that function's return shape, a contract its callers consume. Keys qualify as `<function>.<key>`, so two functions returning the same name stay two shapes rather than one merged symbol, and multiple returns in one function stay distinct by position. RECONCILING THIS WITH R2-1b, which deliberately modelled returned keys as WRITES to avoid adding same-named competitors to narrowing. These are definitions, but narrowing now ranks DECLARED anchors — named literals, class fields, interface and alias members — strictly above return shapes. A name that already resolved keeps resolving to what it resolved to before, so the competitor problem R2-1b was avoiding cannot come back. Mutation-checked: dropping that ranking breaks five pre-existing R2 resolutions. That also required an R2-1b assertion to change, and the change is a strengthening rather than a concession. It asserted `toHaveLength(1)` — no new definition — as a proxy for "adding definitions must not move an existing answer". The proxy is now false while the property still holds, so the property itself is asserted directly. No `HAS_PROPERTY` edge from the function: that would be a `Function|Property` relation pair the schema does not declare, and an undeclared pair does not degrade — it throws and kills the whole analyze. That already shipped once in this PR. Two things found by dumping rather than assuming, both fixed here: SHORTHAND keys were not matched at all. `return { symbol, interval, score }` is the commonest spelling and the reporting repo's own payload is mostly this form, but tree-sitter models it as `shorthand_property_identifier`, which `(pair)` does not match. Caught by dumping the golden fixture and seeing a literal returning `{ level, message, timestamp: Date.now() }` had indexed only `timestamp`. Now covered in return position AND in the variable-bound rule, which had the same gap. Provenance was flagged by owner-presence, which mislabelled the anonymous case: a callback's return shape yields no name to qualify by, so it looked like a DECLARED anchor and would have outranked real declarations. Flagged by position now — a different question from whether a name could be derived. SCHEMA_BUMP 48 -> 49. Within one PR the version only has to differ from main's, but a build stamped 48 was installed and used to analyze before these captures existed, so caches stamped 48 carry none of them — the intermediate-build hazard this ledger already records for 33/34. Golden regenerated after verifying the drift: exactly +10 Property and +10 DEFINES, every pre-existing count unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(scope-resolution): rank production anchors above test fixtures Found by testing R3-4 on the reporting repo instead of on its fixtures. Anchoring returned literals took `wickRatio` from 6 definitions to 13 — and backend reads still resolved to nothing, because SEVEN of the new JavaScript anchors compete and four of them are in `tests/`. A test constructs throwaway shapes carrying production field names; a read in shipped code cannot mean one of them. Applied before the declared/return-shape split, because "is this the shipped program" is the stronger signal — a declaration inside a test fixture is still a test fixture. Skipped when the READER is itself a test, since a read there legitimately means the test's own shape. The first version of this test was vacuous and the mutation check caught it: the reader sat in the same file as the production anchor, so the same-file tier resolved it whether or not this tier existed. The reader now lives in a file that imports neither anchor, which leaves production-vs-test as the only thing that can decide. Honest about what this does NOT do: it narrows `wickRatio` from seven candidates to three, and three functions in different files each returning that field is GENUINELY ambiguous — refusing is correct, and the ambiguity is now counted and named rather than silent. The reported question ("who reads wickRatio?") is answerable only where one producer exists; where several do, the honest answer is the list of producers, which R3-4 made nameable for the first time. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(scope-resolution): resolve members through a call result's return shape The question three rounds of reports could not answer, and the one narrowing must refuse by design: a field produced by SEVERAL functions. A read of `spike.wickRatio` could mean any producer, so name inference correctly declines and no amount of tier-tuning changes that. It needs evidence, not inference. The evidence existed in two halves that had never been joined. The call-result type binding (`const alert = formatSpikeAlert(row)` binds `alert` to a TypeRef whose rawName is the callee) predates all of this work; it simply had nothing to resolve to when the callee returned an anonymous literal, because an anonymous literal named nothing. R3-4 gave it a name. Joining them: const alert = formatSpikeAlert(row); alert.wickRatio -> Property:...:formatSpikeAlert.wickRatio Precise, at ordinary emission confidence, and it works EXACTLY where narrowing cannot: several producers sharing a field name stop being competitors because the receiver says which one. Runs before the name fallback and claims its sites, so a precise answer is never second-guessed by a name match. Measured on the reporting repo: 1,410 precise edges, and all six fields round 3 verified OUT-OF-SAMPLE go from 0 backend readers to 7, 11, 10, 7, 6 and 14. Round 3 scored 0/6 on that set; this is 6/6. The bound is asserted, not just documented: a read off a BARE PARAMETER has no binding here, because typing it needs the caller's type to flow in — that is inter-procedural and genuinely larger. Those reads still fall through to name inference and are still reported when it declines. The fixture has two producers sharing a field name precisely so the test cannot pass by name matching, and mutation-checking the owner lookup fails it. No SCHEMA_BUMP: this is scope resolution, not parse-time capture, so a warm cache already carries everything it reads. Noted in the ledger because the reflex on this branch has been to bump, and an unnecessary bump costs every user a full re-parse.

fix(resolution): resolve calls through a generic-typed field receiver in every language (#2833) (#2855)
* test(resolution): pin generic-typed field receivers across languages (#2833) A field whose declared type carries a type argument (`repo: Repo<User>`) emits zero CALLS edges — not a truncated chain, not an edge to the interface declaration, nothing. This adds the cross-language matrix that measures it, modelled on the #2807 inferred-field matrix: every language runs the same two calls, one through a generic-typed field and one through a non-generic control field, and each language is compared against its OWN control row rather than an absolute edge count. Measured state, pinned here as `known-gap` so the file is green on main and flipping a row is a visible edit: affected TypeScript, C#, C++, Python unaffected Java, Kotlin, Go, Rust, Swift, Dart The unaffected six erase type arguments at interpret time (Java's `stripGeneric`, F41 #1928; Swift likewise). TypeScript, C# and Python instead run a container ALLOW-LIST that returns the type ARGUMENT, so a user-defined `Repo<User>` survives verbatim into a lookup that binds nothing. The `ts-local-vs-field` case is the bug in one file: `viaLocal` and `viaParam` both resolve for the identical type, and only `viaField` loses every edge — a bare name reaches Case 4 and its generic-aware lookup, a dotted field receiver does not. Negative controls pin what erasure must NOT do: an unbounded type parameter denotes no declaration, and a C++ explicit specialization is a different class from its primary template. The `Box2<T>` row pins a PRE-EXISTING false edge (a workspace class named `T`) so it cannot later be mistaken for fallout from this work. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * refactor(resolution): move resolveClassBindingForName to the shared walkers (#2833) Pure relocation, no behaviour change: the generic-aware class lookup moves from `passes/receiver-bound-calls.ts` to `scope/walkers.ts`, beside the bare `findClassBindingInScope` it wraps. Its two existing callers — `classifyReceiverOrigin` and Case 4 — import it from the new home and are otherwise untouched. The move is required rather than cosmetic: `receiver-bound-calls.ts` already imports from `compound-receiver.ts`, so having the compound receiver call into the pass would close an import cycle. `walkers.ts` is the shared floor both already depend on. Verified behaviour-neutral: the #2833 matrix is 44/44 identical before and after, across all fifteen fixtures. detect_changes attributes `resolveInheritanceBaseInScope`, `resolveQualifiedInheritanceBase` and `EMPTY_BINDINGS` to this commit; those are line-shift artifacts of inserting a function above them, and their bodies are byte-identical. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(resolution): type generic field receivers through the generic-aware lookup (#2833) A field receiver is spelled `this.repo` — dotted — so it types through the receiver-chain fold and the text cascade, both of which reach `findClassBindingInScope`. That function has no notion of type arguments, so a field declared `Repo<User>` resolved to nothing and the call site emitted NO edge at all: not the interface declaration, not the implementation fan-out, nothing. A local or parameter of the identical type is a bare name, reaches Case 4 and its generic-aware `resolveClassBindingForName`, and resolved fine. The bug was the asymmetry, not the generics. Three receiver-typing lookups now call the generic-aware helper instead: `typeOfMemberOnClass`'s primary and module-hoist branches, and the cascade's bare-identifier type-binding read. Every other one of the 38 `findClassBindingInScope` call sites is untouched — its own docstring records that widening it globally suppresses the `?? otherResolver(...)` fallbacks two dozen callers rely on, which would retarget inheritance edges, and impact rates it CRITICAL with 12 direct dependents. Order matters and is preserved: the helper tries the exact name, then an arity- and token-exact match against `def.templateArguments`, and only then falls back to the base name. Erasing first would collapse a C++ explicit specialization onto its primary template — `Vec<bool>` really is a different class. A bare type parameter carries no type arguments, so it never enters the generic branch and cannot be erased into a class that happens to share its name. Measured: TypeScript and C# generic-typed fields now emit exactly what their non-generic control rows emit, primary plus interface-dispatch fan-out. Java, Kotlin, Go, Rust, Swift and Dart are byte-identical. Both type-parameter negative controls are unchanged. C++ and Python are still open and stay pinned as known-gaps — they fail for different reasons and get their own commits. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(cpp,python): bind generic-typed member fields so their calls resolve (#2833) Completes #2833 for the two languages the shared resolution change could not reach. Each failed for its own reason, and both were found by measurement rather than assumed. C++ — a CAPTURE gap, not a resolution one. All three `field_declaration` type-binding rules required `type: (type_identifier)`, so a member declared `Repo<User> repo;` is a `template_type` and matched none of them: the field got no type binding at all, and every call through it lost its edge in both the bare and `this->` spellings. A LOCAL of the identical type resolved the whole time, because the local declaration rules gained their `template_type` variant long ago. Three mirrored rules close it, one per declarator shape (plain, pointer, reference). Written as separate patterns rather than one alternation: a node-type alternation in a field position is a tree-sitter 0.21 hazard this repo has been bitten by before. Python — the bracket spelling never entered the generic branch. Its `stripGeneric` is a container allow-list over `[...]` that returns the type ARGUMENT (`list[User]` to `User`), so a user-defined `Repo[User]` matched nothing and survived verbatim, and the shared lookup's generic branch is gated on `<`. It now reduces a subscripted type neither allow-list claims to its base name — the same rule Java and Swift already apply to `<...>`. Deliberately the LAST resort: a container must reach its own rule first, or `list[User]` would type the receiver as the container and retarget every call in a for-loop chain. The as-written spelling survives on `TypeRef.declaredSpelling`, which is what the fold's index step reads. Both are parse-time and land in the cached ParsedFile, so SCHEMA_BUMP goes 45 -> 46 with its pin test. Verified free against origin/main; the ledger in that file records three prior EXACT clashes, so re-check again immediately before merge. The matrix now covers the spellings real code writes, all measured: a nullable generic, a bounded wildcard, a raw type, a nested generic and a multi-argument one. None needed work beyond the shared lookup, which is the evidence that base-name erasure is the right primitive. The C++ specialization control now asserts what it was written for: `Vec<bool>.save` and `Vec.save` are DIFFERENT target ids, so the arity/token match still wins over erasure. scope-capture is byte-identical for cpp and c, so no rebaseline — the bench corpus contains no generic-typed member field, which is worth its own coverage issue. Two pre-existing gaps were measured and are deliberately NOT fixed here, because in both cases the language's own non-generic CONTROL row fails identically: C++ `this->field.m()` emits nothing, and JavaScript/PHP docblock-declared field types bind nothing at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(python): do not reduce containers or typing special forms to a base name (#2833) Review finding on this branch's own Python change, caught by probing the interpreter directly rather than by reading it. The base-name reduction was reached by FALLTHROUGH: "neither container rule matched" was treated as "not a container". It is not, and two measured shapes proved it: dict[str, list[User]] -> dict (was: the annotation, intact) Dict[str, Repo[User]] -> Dict Callable[[int], User] -> Callable Literal["a"] -> Literal Union[A, B] -> Union tuple[int, ...] -> tuple The dict rule's value group cannot span a nested `]`, so a nested value declines and falls through — and the dict rule's own comment says that shape is deliberately "left for a downstream strip pass". Collapsing it to `dict` destroyed the value type instead. The typing SPECIAL FORMS are worse: `Callable`, `Literal`, `Annotated` and `Union` are not classes, and reducing them to a bare name binds any workspace class that happens to share it — a fabricated edge, which is strictly worse than the missing edge #2833 set out to fix, and those names are ordinary enough for a real codebase to declare. Reduction is now guarded by an explicit deny set covering the containers the two allow-lists already own and the typing special forms. Everything named there keeps its as-written text and resolves exactly as it did before #2833. `arr[0]` also reduces to `arr` in isolation, but that is unreachable and is now documented as such: every Python `@type-binding.type` capture is a `(type)`, `(identifier)`, `(attribute)` or `(dotted_name)` node, so a subscripted VALUE expression never reaches the interpreter. Pinned by a new unit test that asserts all four groups — user generic reduces, container reduces to its ELEMENT, declined container shape stays intact, special form untouched. Reverting the deny set fails three of its five cases. Also corrects `resolveClassBindingForName`'s docstring, which this branch had made false: it claimed only `classifyReceiverOrigin` passes the decoration stripper, while the three receiver-typing lookups in compound-receiver.ts now pass it too. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(resolution): rank base-name candidates lexically and refuse arg-pinned defs (#2833) Review of #2855 found that this PR turned a MISSING C++ edge into a CONFIDENTLY WRONG one — the direction this subsystem calls unrecoverable. `resolveClassBindingForName` ended with an unguarded base-name fallback that returned the first same-named class the scope chain reached. A C++ primary template carries `templateArguments === undefined`, so it can never satisfy the exact-args branch, and every non-specialized instantiation fell through to that fallback. Measured through the real pipeline: with the primary forward-declared and the specialization defined first, `Vec<int> vi; vi.save()` emitted `Vec<bool>::save`. Declaring the primary first gave the correct target — selection was SOURCE-ORDER DEPENDENT. Two more triggers behaved the same way: a partial specialization (`Vec<int*>` against `Vec<T*>`), and lexical shadowing between a global `Box<bool>` and a namespaced `N::Box<bool>`. Two changes, neither of which is any of the three remediations the review proposed — each was rejected on measured evidence: - Exact-argument matching is now LEXICAL-FIRST. Candidates come from the scope chain, and the workspace-wide qualified-name bucket is consulted only when the chain produced no exact match, so cross-file specializations still bind. - The base-name route refuses a definition that pinned its own template arguments: if the fallback's answer carries `templateArguments`, the visible candidates are re-decided with those removed — exactly one, or decline. Why not the filed options. "If specializations exist and none matches exactly, return undefined" deletes a green committed row (`neg-cpp-specialization/runInt` legitimately resolves to the primary). "Resolve all defs for the base name, return only on exactly one" deletes a working edge for C# `partial class Repo<T>` split across files — two unspecialized defs under one name is legitimate, and `QualifiedNameIndex`'s own docstring names that case. Preferring the primary alone fixes nothing about shadowing, which is a ranking bug. The guard is expressed as `carriesOwnTemplateArguments`, not as "specialization", so shared pipeline code still names no language (AGENTS.md R6). It can only fire where a declared name carries concrete arguments — measured `undefined` for `class Repo<T>` in TypeScript and C# and for a C++ primary template — so the blast radius is bounded to C++-style specializations. Partial-specialization SELECTION is deliberately not implemented: choosing `Vec<T*>` for `Vec<int*>` needs template-argument deduction, which is a semantics expansion and cannot live in language-neutral shared code. The source-order dependence is what is fixed; the answer is now deterministically the primary. Also in this commit: dropped an unreachable `?? []` (QualifiedNameIndex returns a frozen empty array on miss by contract) whose comment was wrong on both clauses; made the docstring true about argument ERASURE being what widens what binds, rather than only the decoration stripper; and corrected a stale pointer that still placed `resolveClassBindingForName` in `receiver-bound-calls`. `findClassBindingInScope` itself is untouched — 38 call sites, CRITICAL. Verified: matrix 56/56, cpp.test.ts 334, unit scope-resolution 1505. Mutation proof: reverting this file fails the three trigger cases and passes the non-regression cases; restoring it passes all five.

The structural cause is PEP 585: nearly every container has two spellings differing only in case (`deque`/`typing.Deque`, `frozenset`/`FrozenSet`). Exact matching forced every pair to be listed twice, so any half-pair was a silent escape. The deny lookup is now CASE-FOLDED, which closes that axis by construction — `Deque` becomes impossible rather than remembered. `SINGLE_ARG_CONTAINERS` and `MAPPING_CONTAINERS` are now the single source of truth: they build the two container regexes (verified byte-identical `.source` and `.flags`, so zero behaviour change) and feed the property test. The deny set is re-scoped to a closed, auditable universe — the documented Python stdlib type-system surface — and grew 39 -> 65 concepts: the `collections.abc` views, `contextlib` managers, `re.Pattern`/`Match`, the `IO` family, ordinary-named stdlib generics (`Queue`, `Task`, `Future`, `PathLike`), the remaining typing special forms, and the generic machinery (`Generic`, `Protocol`, `TypeVar`...). Third-party generics (`Mapped`, `QuerySet`, `Model`) are deliberately NOT added and are pinned as a decision: that universe is open, enumerating it only chases the last escape, and declining `Model` would cost real edges in the many projects that declare one. The review's suggested property test — derive the names from the `single`/`dict` regex sources — would NOT have caught `Deque`: `deque` appears in neither regex, only in the deny set. Both properties are implemented, since they catch different drift. The unit test was also TAUTOLOGICAL: it asserted members OF the deny set, so it structurally could not detect an omission. It now asserts case-fold closure and PEP 585 alias coverage, and the capture fixture drops its `as unknown as` cast for the fully-typed helper pattern the sibling `java-interpret.test.ts` already uses. Still at interpret time, so no further SCHEMA_BUMP (already 45 -> 46). Proving the base is a class the FILE can see — the real fix for the remaining exposure, since `findClassBindingInScope` binds any name with exactly one workspace def regardless of scope or imports — is a follow-up, not reachable from this file. Mutation proof: restoring HEAD's deny-set contents and exact-match lookup fails four assertions including the `Deque` pair, with the pre-existing guard rows still passing; restoring gives 125/125. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(cpp): capture qualified generic member fields, and make the bench gate see them (#2833) Review of #2855 found that the three `field_declaration` rules this PR added only matched a DIRECT `template_type`, so the common real-world spelling still bound nothing: `std::vector<Item> items;`, `ns::Repo<User> r;` and `std::unique_ptr<Repo> p;` parse as a `qualified_identifier` WRAPPING a `template_type`. "C++ fixed" was overstated. Six new patterns — three declarator shapes (plain, pointer, reference) by two qualifier depths — written as separate patterns rather than one alternation, keeping the tree-sitter 0.21 field-position discipline the existing rules follow. The design choice was measured, not assumed. Codex suggested preserving the full qualified spelling and normalizing `::`; preserving resolves NOTHING, because `findClassBindingInScope`'s dotted-tail fallback splits on `.` while C++ writes `::`, and `ns::Repo` is not an index key either (C++ emits no `@declaration.qualified_name`). Measured: `ns::Repo<User>` resolves to nothing, `ns.Repo<User>` resolves to `Repo`. Since a tree-sitter capture is a NODE and not synthesized text, the only lever is which node to capture — so `@type-binding.type` goes on the INNER `template_type`, dropping the qualifier and landing on the same single-match-or-decline path the bare spelling already takes. Qualifier depth 3+ (`a:🅱️:c::Repo<User>`) remains uncaptured. Stated as a limit and pinned by a test row, not claimed as fixed. The bench blindness the review identified is also closed. The `scope-capture` C++ corpus contained ZERO template-typed member fields — confirmed a fourth way by applying six demonstrably behaviour-changing patterns and getting a byte-identical fingerprint. The corpus now carries generic and qualified-generic members, and the gate is load bearing for the first time: three states that all hashed to 856d02f3 before now differ (pre-#2833 0e7cbda7, +this PR's 3 rules de07d8b5, +these 6 rules bd47c82d). Rebaselined for cpp only; c is unchanged. Histogram diff: only 5 tags move with the fields, each by exactly +40 (20 entities x 2), and every `@reference.*` count is unchanged. Over-match is preserved: 20 shapes still produce no field capture, including the 8 original method/pointer/reference/function-pointer/ using/typedef/friend/operator forms plus their `std::`- and `a:🅱️:`-qualified variants. Not fixed here, deliberately: NON-generic qualified fields (`ns::Address addr;`, `std::string name;`) still capture nothing. Closing that needs six more patterns and would newly bind every `std::string`/`std::mutex` member repo-wide, changing edges far outside #2833. Separate issue. The template-template-parameter hazard the review filed against these rules is NOT capture-side: a tree-sitter query has no scope knowledge, so it cannot know `Map` is bound by the enclosing `template <...>` header, and the PRE-EXISTING `type: (type_identifier)` rule already captures a bare `T item;` and erases it the same way. It is handled by the lexical ranking in `walkers.ts` in this series. Mutation proof: reverting this file fails 9 of 32 assertions (all eight qualified spellings return no capture) while every over-match negative still passes; restoring gives ALL PASS. Bench `--check` passes for all 15 languages.

The rows that discriminate against the resolver fix (they fail if `walkers.ts` is reverted): - C++ specialization must not depend on DECLARATION ORDER: the forward-declared-primary/specialization-first arrangement must land on the primary, same as the mirror arrangement. Plus a cross-case property asserting the two independently built fixtures agree. - Partial specialization is deterministic in both orders. The note says explicitly that selecting `Vec<T*>` would need argument deduction and that flipping this row later is a deliberate expansion, not a regression fix. - Lexical shadowing: the namespace-local `N::Box<bool>` wins for a field inside `N`, and the global specialization wins at global scope. The NON-REGRESSION rows are load-bearing — they are why two of the three proposed remediations were rejected: cross-file C++ specialization binding, and C# `partial class Repo<T>` split across two files with the field in a third (two legitimate unspecialized defs under one name). Coverage the review found missing: C++ pointer and reference generic fields (two of this PR's three original rules had ZERO coverage); all six qualified patterns plus the depth-3 boundary pinned as empty; TS/C# multi-arg container collision; an anti-vacuity sibling for `neg-bounded-type-parameter`; Swift/Dart rows restructured so the ANNOTATION is the only possible source (the old rows gave the field an initializer of the same generic type and could not tell which resolved); and cross-file, inheritance/MRO, import-alias, static-member and the TypeScript module-hoist branch. Six things were measured and pinned AS MEASURED rather than asserted as wishes, each flagged in its row note: a static/class-level member emits nothing for generic AND non-generic alike (a static gap, not a generics one); a cross-file C++ primary template does not bind while the cross-file specialization does; `std::unique_ptr<Payload>` types to `unique_ptr` rather than `Payload` (smart-pointer transparency is not applied on the qualified path); two same-named C++ specializations in one file collapse to one node id; and the container-name collision (`Map<string, User>` binding a workspace `class Map`) is recorded as INTENDED, since the annotation does name that class. The `new Set(...)` dedup was kept rather than narrowed: a per-case surplus-edge sweep measured ZERO duplicate edges anywhere in this file, Swift included, so the quirk that justified a blanket dedup does not reproduce. The sweep now pins zero surplus per case, so a real double-emit fails instead of being absorbed. The file is deliberately NOT split: four assertions compare cases against each other, cost is linear in cases, and the 1,800,000 ms `beforeAll` is kept because the same run measured 271-428 s depending on host load — a tighter bound converts contention into a red suite. The reasoning is recorded in the file header. Also corrects the SCHEMA_BUMP pin-test title, which still said (#2766). Mutation proof: reverting `walkers.ts` fails exactly the five order and shadowing assertions and passes the other 109; restoring gives 114/114. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * feat(resolution): capture declared type parameters so a type variable is not a class (#2833) Three review findings were blocked on one missing fact. `templateArguments` records the arguments a declaration was written AGAINST (`struct Vec<bool>`); nothing recorded the parameter list a declaration DECLARES (`template <class T>`, `class Box<T extends Repo>`). So the resolver could not tell a type variable from a class, and: - `class Box2<T> { t: T }` beside a workspace `class T` emitted a FALSE edge `run2 -> T.foo`. `T` carries no type arguments, so it never entered the generic branch — the plain lookup simply bound a same-named class. The lexical grounding added elsewhere in this series cannot help, because `export class T` IS lexically bound. - `class Box<T extends Repo> { t: T }` resolved to nothing: no recorded bound to resolve through. - A full specialization `template<> struct Vec<T*>` and a partial `template<class T> struct Vec<T*>` were byte-identical (`['T*']`). `SymbolDefinition.typeParameters` now records `{ name, bound? }` in declaration order (substitution is positional). `bound` is kept verbatim and un-split, so `Repo & Closeable` stays whole; ABSENT means UNKNOWN, never "unbounded", which is what keeps unconverted languages behaving exactly as before. Transport is the raw parameter-list node via `@declaration.type-parameters`, read by a language-neutral parser that recognizes TOKENS, not languages: `extends`/`:` introduce a bound, the name is the trailing identifier, so `class T`, `typename T`, `in T`, `out T`, `reified T` and `class... Ts` are one rule. Populated for TypeScript, C++, Java, Kotlin, C# and Rust. JavaScript, C, COBOL, PHP and Ruby have no declared type parameters to capture; Go and Python spell them with SQUARE brackets, which this parser deliberately rejects as ambiguous against subscript and array spellings (Go already has a working main-thread sidecar in this series); Dart and Swift are straightforward follow-ups. Two latent hazards found and closed on the way: - The new capture was not in `KNOWN_SUB_TAGS`, so it could out-span its own declaration and become the anchor — silently DROPPING the whole class def. - A templated C++ struct matches both the standalone and `template_declaration` patterns, minting two defs under one id, and only one twin could see the parameter list. `buildDefIndex` is first-write-wins, so MATCH ORDER decided whether `Vec` remembered `T`. A narrow duplicate-declaration backfill gives both twins the list. Also fixed by its own test: a Rust lifetime `'a` parsed as a parameter named `a`, which would have shadowed a real class. Parse-time output lands in the cached ParsedFile, so SCHEMA_BUMP goes 46 -> 47. Re-checked against origin/main at write time: main is on 45; 46 was taken by this same branch, and a warm cache stamped 46 carries ParsedFiles with no `typeParameters` at all. The csharp and rust capture goldens were regenerated with the tests' own documented `UPDATE_GOLDEN=1`; only digests moved, no captureGroups. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(resolution): ground erased base names, and stop a class name from being enough (#2833) The review's central risk was that this PR converts MISSING edges into CONFIDENTLY WRONG ones. Base-name erasure (`Repo<User>` -> `Repo`, `Repo[User]` -> `Repo`) bound through a workspace-wide qualified-name fallback that consults NO scope, NO import and NO module — it bound any name with exactly one workspace def. That is why a Python `Mapped[User]` could bind an unrelated `class Mapped`, and why the language deny lists were papering over an open universe. `resolveErasedBaseName` now admits an erased base on one of four grounds, strongest first: the scope chain binds it; the declaration is in the SAME FILE; the index proves the name is a template family; or the file binds no cross-file class at all, so its silence is no evidence. The last ground fails toward permissive on purpose — every way it can be wrong costs a wrong edge that already existed, never a working one. Two measurements drove that design and refuted the simpler rule. A C++ `#include` materializes NO binding whatever, and C# resolves cross-namespace without `using` through the index — so a pure "require lexical grounding" rule would have deleted every cross-file C++ generic member. Both are now pinned. Python erases at CAPTURE time, so by resolution there is no `<` and the grounded route was never entered. `erasedTypeApplication` rebuilds the application from `TypeRef.declaredSpelling` — strictly: the raw name must be the base and the argument list the whole balanced remainder, so `User[]`, `vector<Item>` and `Repo<User>?` decline and behave exactly as before. Closing it took finding FOUR emitters, not one. Three were in Case 4; the fourth was `emitReferencesViaLookup` re-emitting the refused edge from the pre-resolved reference index, which needed the site marked handled with a recorded `receiver-unresolved`. A fifth lived in the text cascade: a declined fold falls THROUGH by design, and the cascade held its own ungrounded copy of the member-typing lookup. This file typed a receiver from a `TypeRef` in five places and the PR had wired three; all five now go through one `classOfDeclaredType`. Also here, from the same review: - Type parameters no longer bind a same-named class (uses the new `typeParameters`), and a BOUNDED parameter resolves through its bound. - A cross-file C++ PRIMARY template now binds: a ranking bug, not a capture one — the index fallback needs exactly one candidate and `Vec` held two, so removing the argument-pinned declaration leaves one. - `this->field.m()` resolved to nothing for generic AND non-generic alike. A language that declares `this` IS the enclosing class (`resolveThisViaEnclosingClass`) synthesizes no `this` typeBinding, so a chain whose BASE is `this` could never seed its head. Reading the provider flag keeps the rule language-free. - Class-level (static) member receivers emit nothing in TypeScript and Kotlin — for the non-generic control too. Case 6 types them from the DEF side (`isStatic` + `declaredType` on the field node), which needs no capture change; the target lookup stays the ordinary instance walk, so a static field HOLDING an instance still binds an instance method and a genuine static call is untouched. Partial-specialization SELECTION is deliberately not implemented: it needs argument deduction against a parameter list, and full C++ partial ordering is a real algorithm with no measured driving case. The discriminator now exists if someone wants it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * fix(cpp,js,php,go): close the remaining per-language generic-field gaps (#2833) Four language gaps the review measured, each with a different cause. **C++ qualified member fields.** `std::vector<Item> items;`, `ns::Repo<User> r;` and `ns::Address addr;` captured NOTHING: every field rule required the type node to BE a `type_identifier` or `template_type`, and a qualified member type is neither — tree-sitter wraps both in a `qualified_identifier`. Three depth-agnostic rules (one per declarator shape) now match the outer node, which also REMOVES the depth boundary rather than raising it: depths 1-4 capture, generic and non-generic alike. Preserving the qualifier resolves nothing — measured: `ns::Repo<User>` binds neither way, because the dotted-tail fallback splits on `.` while C++ writes `::`, and `ns::Repo` is not an index key. Since a capture is a NODE and not synthesized text, the qualifier is dropped in `interpret.ts` by a top-level-only `::` split, so `std::vector<std::string>` reduces to `vector<std::string>`, not `string`. Measured cost of the non-generic half, which was the reason to hesitate: field captures go 8 -> 32 across the C++ bench corpus, but the resolution-level census over those 13 repos is 32 CALLS edges before and 32 after, BYTE-IDENTICAL. It fabricates only where a workspace class shares a std name (`class string` beside `std::string name;`), which is the same accepted policy the already-landed qualified-generic rules carry, pinned in the matrix as intended. **JavaScript `@type {Repo<User>}` and PHP `@var Repo<User>`.** Neither bound a field type — and neither did the NON-generic control, so this was a docblock gap rather than a generics one. PHP needed TWO captures, not one: with only the type binding, `$this->repo->save()` resolved until a second class declared `save` and then went unresolved, because narrowing a same-named method needs the receiver's member owned. Generics do NOT come free in PHP — `normalizePhpType('Repo<User>')` returns `'User'` by the container-element convention, so passing the raw spelling through would have emitted `User::save`; type arguments are erased at capture instead. In JavaScript they DO come free, verified byte-identical to the TypeScript control. Both decline what they cannot prove: arrays, `list<User>`, unions, `Promise`/`Array` wrappers (via an exported predicate rather than a copied name list), statics, and any property that already has a native type. **Go generic interfaces.** `UserRepo` genuinely DOES implement `Repo[User]` — the spec says a generic type must be instantiated, that instantiation substitutes type arguments and yields a new non-generic type, and that a type implements an interface when it is in its type set. So the old behaviour was a FALSE NEGATIVE and the matrix note calling it "already correct" was wrong. Satisfaction is now checked against POSITIONALLY SUBSTITUTED method sets, so `Repo[Order]` does not match a `Save(x User)` implementor — substitution, not erasure. #2829's exact method-set model is untouched: pointer receivers still follow MS(*T), unexported names stay package-scoped, the declaration's own method set is still checked first, and the harvest is gated so a repo with no generic interface never runs it. `go.test.ts` is unchanged at 296 passing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * test(resolution): pin every fix from the review, 114 -> 155 rows (#2833) Eight rows in this matrix pinned gaps that the fixes in this series close, so each asserted the opposite of the new truth. All eight are flipped, and the prose describing them as open gaps is corrected. Nine new cases cover the fixes that would otherwise have shipped unpinned. Flipped, each measured: the type-parameter FALSE edge (`run2`) is gone; a bounded parameter now resolves through its bound with fan-out; the cross-file C++ primary binds; the C++ qualifier depth boundary is removed rather than raised; Go gains its two structural implementors and JOINS the paired sweep, which had quietly excluded it — that exclusion was the taxonomy admitting a bug; and both static-member rows resolve. Added: JS `@type` and PHP `@var` docblock fields with three PHP declines; a Kotlin `companion object` receiver (given an INTERFACE control so the paired sweep can check it, which `ts-reach-shapes` cannot — its two sides are not count-comparable); the Python third-party grounding refusal plus the ground that still ADMITS, so an empty row can never be read as "erased names never resolve"; the four mirrors that would break if grounding were tightened (same-file and imported Python, a C++ `#include`, C# cross-namespace without `using`); C++ qualified non-generic fields including the fabrication policy and its absence case; `this->field.m()` for generic and non-generic with bare controls; and a Go negative proving substitution is positional, not erasure. Three shapes are pinned AS MEASURED with notes saying they are deliberate limits so nobody "fixes" them by accident: C++ partial-specialization selection is deterministically the primary (real selection needs argument deduction); `std::unique_ptr<T>` types to the pointer, not the pointee (`.` and `->` are indistinguishable to the resolver, so transparency would trade a recoverable miss for a confident wrong edge); and two same-named C++ specializations in one file collapse to one node id, which is why the shadowing fixture uses two files. One row pins a REMAINING wrong edge rather than hiding it: `m.inner.ping()` on a `Mapped[User]` head still binds the unrelated workspace class, while the one-segment-shallower `m.save(u)` correctly declines. The obvious one-line guard was written and MEASURED not to close it, so the surviving route is elsewhere and wants its own diagnosis — a broader refusal would change chain-head resolution for every language without pinning the shape it is meant to fix. `bench/scope-capture` is rebaselined for the six languages whose captures moved, regenerated from a fresh measurement rather than pasted; `--check` passes for all 15. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * perf(resolution): remove three measured hot-path regressions this series added (#2833) A quality pass over the #2833 series found three performance defects it had introduced, all measured, plus dead code and stale docs from six agents having appended to the same files across four rounds. No behaviour change: the resolver suite is identical before and after, and every scope-capture fingerprint is byte-identical. **An accidental quadratic in Go instantiation harvesting.** `collectGoInstantiations` calls `record()` for every type binding and every declared, return and parameter type in every Go file, and the `includes('[')` gate does not filter Go's most common types — `map[string]string`, `[]map[string]*v1.Pod` and `map[string]map[string]int` all produce a `map` candidate. Each false base then failed a full scope-chain walk and fell through to a LINEAR SCAN OF EVERY INTERFACE IN THE PROGRAM, with no dedupe on the spelling, so the same `map[string]string` written 10,000 times paid 10,000 scans. Now a qualified-name index built in `buildDetectionIndexes` (one probe, ambiguity semantics preserved exactly) plus a per-scope base memo: 8,000 interfaces / 80,000 spellings: 6,662 ms -> 104 ms (64x) `resolveEmbeddedInterface` held a byte-identical copy of that scan and now shares the helper. `GoInstantiation` was a single-field wrapper and collapses to the array it wrapped; its two parallel maps fold into one whose inner key IS the dedupe. `candidateStructIdsFor` was rebuilt per instantiation although every substituted method set has the same key set — hoisted, and materialized, because one branch returned a live iterator that would have yielded nothing on a second pass. **`scanForCrossFileClass` asked a name-keyed question that needs no name key.** It answered "does this file bind any cross-file class" by probing every accessible namespace once PER NAME. It now iterates the channels directly, taking whichever side is smaller so a large namespace table cannot reintroduce the product. Predicate and early exit preserved: 5,000 module names x 1,000 namespaces: 159.0 ms -> 1.2 ms (132x) **A duplicated scope walk on every generic receiver.** `resolveClassBindingForName` computed the lexical candidate list, then `resolveErasedBaseName` recomputed the identical `findAllBindingsInScope`. Computed once and passed: receiver at depth 8: 5,617 ns -> 3,091 ns (-45%) **A whole extra AST traversal per JavaScript and PHP file.** The docblock synthesis passes each added a full tree walk to find one node kind — the ninth in the JS emitter, the third in PHP. `node.namedChildren` materializes a wrapper array across the N-API boundary for every node, so one added pass cost 1.9x what parsing the entire file costs. Folded into the existing walks as one more node kind; capture output is byte-identical and every fingerprint is unchanged. Total emit time per file drops 4-7%. Hygiene, all verified stale rather than assumed: - `receiverOriginOpts` passed `resolveThisViaEnclosingClass`, which `classifyReceiverOrigin` never reads — the "both hooks" comment above it is true again. - The `stripDecoration` docstring's caller roll-call claimed the only edge-emitting caller "emits no edge and can only change a diagnostic label". Case 6 passes it and does emit edges. Replaced the roll-call with the rule; six rounds each appending a name to a list is how it went wrong. - A Python comment described the resolution-time grounding as a follow-up that "this parse-time pass cannot do" — it landed in this same branch and is pinned by `py-erased-grounding`. - `classOfDeclaredType` took a `scopeId` all five callers derived from the `TypeRef` they also passed. Dropped, so "these five are the same call" is enforced rather than asserted. - Three exports with no consumer outside their own file. - PHP had three copies of one preceding-comment sibling walk and two regexes for one tag, so a fix to either reader of `@var` would land on one and not the other — the symptom being a field typed differently from its own foreach element type. One walk, one regex. Tests: the new matrix leaked a fixture repo per case; it now carries the sibling suite's `cleanupTempDirSync` and the Windows EBUSY reasoning that goes with it. `PAIRED` was a second hand-maintained list and 19 of 41 cases had silently fallen out of it — it is derived from the cases now, with a new assertion that each case is either swept as a pair or carries a written reason it is not. That recovered one genuine omission (`php-typed-property`). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KtNfG6EPn738Y51AYs7wDp * test(bench): rebaseline receiver-resolution for the #2833 this-> fix The `Receiver-resolution drop guards` CI step failed on this branch: shapeArm.cpp.fieldReceiverCall: "INVISIBLE-GAP" -> "RESOLVES" shapeArm.cpp.decoratedFieldType: "INVISIBLE-GAP" -> "RESOLVES" Both are the intended improvement. The guard is exact-match by design — the drop count cannot move without a deliberate rebaseline, and the rebaseline path demands the movement be explained — so this records the two shape flips and leaves the call-drop count arm untouched. BASELINE.md still claimed `this->repo.save()` and `this->repo->save()` were INVISIBLE-GAP. That is now false: the `resolveThisViaEnclosingClass` head seed added in this PR resolves both. Also notes what the control established — this was never a generics gap, since the non-generic control failed identically before the fix. * docs(parse-cache): narrow the SCHEMA_BUMP ledger to what the bump delivers The ledger claimed a warm cache would make "the whole fix ... a silent no-op on every incremental analyze". That overstates the constant. The bump invalidates the PARSE half; whether the re-parsed captures reach the graph is gated separately and does not move: - `isIncremental` (core/run-analyze.ts) tests `!options.force`, an existing meta, `!schemaFingerprintMismatch(...)`, feature parity, non-empty `fileHashes` and a git repo. SCHEMA_BUMP is in none of them. - the incremental branch writes back only `hashDiff.toWrite` and logs the rest as "unchanged file rows preserved". - SCHEMA_FINGERPRINT hashes node/relation DDL, untouched here, so it is byte-identical and moves nothing either. So an incremental analyze re-parses an unchanged file correctly but keeps its existing rows; the new edges land on the next full rebuild. That is the pre-existing contract for every capture change, not a regression in this PR — but the comment should not promise more than it delivers. Comment only; no behavior change. SCHEMA_BUMP stays 48. --------- Co-authored-by: Gergo Magyar <gergomagyar0@gmail.com> Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |
