  - `extractPendingAssignment` in per-language type extractors captures `let x = getUser()` patterns
  - Unified fixpoint loop resolves variable types from function return types after initial walk

  - Method-call-result chaining: `user.getProfile().bio` resolves through intermediate return types
  - 22 new test fixtures covering call-result and method-chain binding across all supported languages
  - Integration tests added for all 10 language resolver suites
- **ACCESSES edge type** with read/write field access tracking (#372)

- **tests**: update property edge and write access expectations across multiple language tests
- **docs**: corrected stale "single-pass" claims in type-resolution-system.md to reflect walk+fixpoint architecture

### Changed
- **Upgrade `@ladybugdb/core` to 0.15.2** and remove segfault workarounds (#374)
- **type-resolution-roadmap.md** overhauled — completed phases condensed to summaries, Phases 10–14 added with full engineering specs

## [1.4.6] - 2026-03-18

### Added
- **Phase 7 type resolution** — return-aware loop inference for call-expression iterables (#341)
  - `ReturnTypeLookup` interface with `lookupReturnType` / `lookupRawReturnType` split
  - `ForLoopExtractorContext` context object replacing positional `(node, env)` signature

  - PHP `$this->property` foreach via `@var` class property scan (Strategy C)
  - PHP `function_call_expression` and `member_call_expression` foreach paths

  - `pendingCallResults` infrastructure (dormant — Phase 9 work)

### Fixed

### Changed
- **Migrated from KuzuDB to LadybugDB v0.15** (#275)

- Worker pool threshold — skip worker creation for small repos (<15 files or <512KB total)
- AST walk pruning via `SKIP_SUBTREE_TYPES` for leaf-only nodes (string, comment, number literals)
- Pre-computed `interestingNodeTypes` set — single Set.has() replaces 3 checks per AST node
- `fastStripNullable` — skip full nullable parsing for simple identifiers (90%+ case)
- Replace `.children?.find()` with manual for loops in `extractFunctionName` to eliminate array allocations

### Fixed
- Same-directory Python import resolution (#328)
- Ruby method-level call resolution, HAS_METHOD edges, and dispatch table (#278)
- C++ fixture file casing for case-sensitive CI
- Template string incorrectly included in AST pruning set (contains interpolated expressions)
