* feat(scope-resolution): migrate Dart to registry-primary call resolution (#939)
Add a Dart scope-resolution module (languages/dart/) mirroring the Swift
template and flip Dart to registry-primary. Resolution edges
(CALLS/IMPORTS/ACCESSES/EXTENDS/IMPLEMENTS/METHOD_IMPLEMENTS) now route
through the shared registry pipeline with byte-for-byte parity against the
legacy DAG: test/integration/resolvers/dart.test.ts passes 53/53 under both
REGISTRY_PRIMARY_DART=0 and =1 (scripts/run-parity.ts --language dart: 2/2).
Dart-specific handling:
- Function scopes are synthesized to span signature..body (tree-sitter
function_signature/function_body are siblings, not parent/child).
- extends rides @reference.inherits (EXTENDS via the generic pre-pass);
implements/with are carried as __heritage__ side-effect imports and
emitted as IMPLEMENTS, since Dart `implements <class>` must be IMPLEMENTS
regardless of the target's symbol kind.
- imports are wildcard (whole-library) with expandsWildcardTo so imported
return types propagate cross-file (var u = getUser(); u.save()).
- getInnerSignature now self-returns a bare signature node so top-level
function params/return/name extract (legacy-safe: legacy only ever passes
method_signature/declaration wrappers).
Also: add Dart scope-capture bench coverage (linear ~0.99 scaling); update
two tests that used Dart as a non-migrated control (Vue / forced legacy).

* fix(scope-resolution): close Dart registry-primary parity gaps from review
Adversarial review of #1970 surfaced real divergences from the legacy DAG on
constructs the 10 fixtures don't exercise. All fixed; parity gate still 2/2
(now 55/55 each mode):
- Implicit-constructor construction (`Foo()` with no explicit ctor): the
legacy DAG emits `caller -> Foo` (Class) but registry emitted nothing
(callee tagged @reference.call.free never reaches constructorCallTargetsClass).
Re-tag UpperCamelCase free-callees to @reference.call.constructor (Dart types
are UpperCamelCase) so they link to the Class. Locked in with a regression
fixture + test that passes in BOTH modes.
- Cascade calls (`list..add(1)..sort()`) were dropped — cascade_section has no
`selector` wrapper, so the reference walk never saw them while legacy emitted
them as free calls. Add a cascade_section handler.
- BUILT_INS (setState/then/push/pop/listen/...) were not suppressed on the
registry path, so a user symbol shadowing one produced a spurious CALLS edge
the legacy DAG suppresses. Skip built-in-named call refs at capture time
(extract the set to a leaf module shared with the provider).
- Enhanced-enum methods mis-parented to Module (no enum scope). Add
`(enum_declaration) @scope.class` so enum members are owned by the enum.
Re-baseline the Dart scope-capture fingerprint (linear ~0.95).

* feat(scope-resolution): apply issue #1926 F24/F25 findings to the Dart scope path
Issue #1926 catalogs Dart parsing-layer coverage gaps. Apply the two that the
registry-primary scope-resolution path owns (call edges + call attribution),
registered as legacy-expected-failures since they are scope-resolver-only wins.
- F24: the scope path's unified tree-walk already captures member calls
(obj.method()) in return / list-literal / named-argument / arrow-body
contexts — the legacy DAG only captures them under expression_statement /
initialized_variable_definition. Lock it with the dart-member-call-contexts
fixture + tests.
- F25 (constructor portion): a constructor's body is a sibling of the WRAPPING
method_signature (class_body > method_signature > constructor_signature, then
function_body), so findFunctionBody now walks up to the method_signature
wrapper. Constructor bodies get a Function scope and their body-calls
attribute to the Constructor (a valid caller anchor) instead of the class.
Add the dart-constructor-body fixture + test.
Switch dart.test.ts to createResolverParityIt('dart') and add the dart entry to
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES (5 wins). Both modes pass:
run-parity --language dart → 2/2 (registry 60/60; legacy 55 pass + 5 skipped).
Not applicable to the scope path (structure-phase / shared-pipeline, tracked by
#1926's legacy fix): F25 getter/setter (Property is not a caller anchor) and
operator (no Method node emitted by the structure phase) bodies; F26 (static
field Property nodes); F27 (no generic_type reference in the scope module);
F28/F29 (typedef/variable node extraction). Re-baseline the Dart scope-capture
fingerprint (linear ~1.0).

* fix(scope-resolution): fix Dart named-constructor file-drop + container-name mis-binding (tri-review)
Multi-engine tri-review (GitNexus + CE personas + Codex gpt-5.5) of #1970
found a P0 the parity gate missed plus a P2 wrong-edge:
- P0 (file drop): a named constructor with a body (`class A { A.named() {…} }`,
idiomatic Dart) parses as ONE constructor_signature carrying multiple `name:`
fields, so the scope query matched it more than once and synthesized two
identical-range @scope.function captures → ScopeTreeInvariantError(duplicate-
scope-id) → extractParsedFile swallowed it → the WHOLE file was dropped from
registry-primary resolution (CALLS=0 vs legacy CALLS=2). Introduced by the
#1926 F25 findFunctionBody change that started giving constructors body
scopes. Fix: dedup function-like declarations by their statement node so each
is emitted once. Add dart-named-constructor-body fixture + a parity guard test
(both modes) that fails if the file is dropped, plus the named-ctor F25
attribution win (registry-only).
- P2 (wrong edge): normalizeDartType's Future<X>/List<X> unwrap is unreachable
(generic args are stripped upstream to a bare `Future`/`List`), so a return/
field type binding to the bare container name let a same-named user class
(`class Stream {…}`) capture the receiver — a wrong CALLS edge legacy didn't
emit. Suppress type bindings that normalize to a bare container name (leaving
the call unresolved, matching legacy) instead of binding to the container.
Both modes still pass: run-parity --language dart → 2/2 (registry 62/62; legacy
56 + 6 skipped). Re-baseline the Dart scope-capture fingerprint. Also: refresh
the captures.ts module doc (constructors get scopes; cascade calls).

* fix(scope-resolution): address Dart tri-review follow-ups (heritage collision + polish)
- P2 heritage cross-file name collision: emitDartHeritageEdges resolved both
child and base by a global last-write-wins simple-name map, so two files each
declaring `class Logger` (one `implements Logger`) produced a wrong-file
IMPLEMENTS edge. Resolve with same-file affinity (prefer a same-file class,
then a workspace-unique match, else refuse to guess) — the #1951 file-affinity
pattern. Add dart-heritage-name-collision fixture + a parity test (both modes
resolve same-file). Also reason-qualify the dedup key so `implements X` + `with X`
keep distinct edges.
- Polish: buildDartMro uses Sets instead of Array.includes-in-loop; merge-bindings
uses named tier constants matching swift; drop the dead no-op stripQuotes in
import-target (targetRaw already arrives quote-stripped).
Both modes pass: run-parity --language dart → 2/2 (registry 63/63; legacy 57 + 6
skipped). Re-baseline the Dart scope-capture fingerprint.
