fix(parity): align WASM/native extraction for swift and jelly-micro fixtures#1594
Conversation
…ixtures
swift:
- WASM extractors/swift.ts: navigation_expression calls used navigation_suffix
child text (".save") rather than descending into the simple_identifier. Adds
seedSwiftPropertyTypeMap() to also set typeMap from class-body property
type annotations so receiver edges resolve correctly (repo -> UserRepository).
- Rust extractors/swift.rs: mirrors the navigation_suffix fix — descends into
find_child(&n, "simple_identifier") to extract the bare method name.
- Both engines now produce identical calls (name="save", receiver="repo") and
the 3 missing receiver + calls edges in the swift fixture.
jelly-micro:
- WASM extractors/javascript.ts: extractObjectLiteralFunctions was only called
for const declarations. Adds extractLetVarObjLiteralDeclarators() to emit
qualified method definitions (var.method) for let/var object literals,
called from extractConstantsWalk (which provides the function-scope guard).
Also adds the equivalent in handleVariableDecl for the walk path.
- 12 missing nodes (x.a, q1.m1, k1.a1, x12.f13, etc.) now produced by WASM.
Note: no Rust change needed — match_js_objlit_qualified_method_defs already
handles let/var correctly.
erlang divergence pre-dates this run — no WASM grammar available (issue #1582
filed). All other 35/36 fixtures are now wasm == native.
Verification: cargo test (419 pass), vitest (3125 pass), resolution benchmark
(176 pass), parity audit (35/36 clean, erlang excluded per #1582).

Greptile SummaryThis PR fixes two WASM/native parity divergences found during the Titan audit: Swift's
Confidence Score: 5/5Safe to merge — both fixes are well-scoped, have regression tests, and the two JS extraction paths are mutually exclusive so there is no risk of duplicate definitions. The Swift changes correctly descend into navigation_suffix in both Rust and TS extractors and are symmetric. The JS changes add let/var object-literal method extraction at exactly two independent code paths (query and walk fallback) with matching scope guards; the paths cannot both fire for the same input. All new behaviour is covered by targeted regression tests. No files require special attention. Important Files Changed

The comment says the TypeScript "Mirrors Rust match_swift_node which reads node_text of the last child directly (which equals .method)." That describes the old broken Rust behavior — but match_swift_node in swift.rs is also updated in this same PR to descend into navigation_suffix via find_child. The Rust no longer reads the last child's text directly, so framing the TypeScript fix as "mirroring" an already-fixed Rust behavior is misleading and will confuse future readers of this comment.
Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Fixed — the comment now says both TS and Rust descend into navigation_suffix via find_child to extract the inner simple_identifier, with a dot-strip fallback. Commit: b0f5fd0.

The PR summary says "Native extractor missed object-spread property extraction — javascript.rs updated to handle { ...obj } spread patterns." However, this diff contains no changes to crates/codegraph-core/src/extractors/javascript.rs, and the actual code here handles method definitions inside let/var object literals ({ m() {} }, { k: () => {} }), not { ...obj } spread patterns. If javascript.rs already had match_js_objlit_qualified_method_defs before this PR, it would be helpful to confirm that explicitly; if it still needs to be added, that fix appears to be missing. Did crates/codegraph-core/src/extractors/javascript.rs already have match_js_objlit_qualified_method_defs for let/var object literals before this PR? The description implies javascript.rs was changed here, but no diff for that file is present. If Rust was already correct, the description is just wrong; if Rust still needs the fix, it's missing from this PR.

Investigated — match_js_objlit_qualified_method_defs already exists in javascript.rs (no change needed there). The PR description's mention of spread patterns and javascript.rs changes was inaccurate. The TS function extractLetVarObjLiteralDeclarators mirrors the existing Rust equivalent. Updated the JSDoc to say exactly that: it mirrors match_js_objlit_qualified_method_defs in javascript.rs. Commit: 0301a61.
