ceb7baffb5 feat(mir): Phase 136 Step 7/7 - CompilationContext extraction 
**Step 7/7 Complete**: Extract compilation-related fields into CompilationContext

**抽出したフィールド** (15個):
- compilation_context: Box compilation context
- current_static_box: Current static box name
- user_defined_boxes: User-defined box registry
- reserved_value_ids: Reserved ValueIds for PHI
- fn_body_ast: Function body AST for capture analysis
- weak_fields_by_box: Weak field registry
- property_getters_by_box: Property getter registry
- field_origin_class: Field origin tracking
- field_origin_by_box: Class-level field origin
- static_method_index: Static method index
- method_tail_index: Method tail index (fast lookup)
- method_tail_index_source_len: Source size snapshot
- type_registry: Type registry (TypeRegistryBox)
- current_slot_registry: Function scope SlotRegistry
- plugin_method_sigs: Plugin method signatures

**新規ファイル**:
- src/mir/builder/compilation_context.rs (435 lines)
  - CompilationContext struct with 15 fields
  - Helper methods for all compilation operations
  - Comprehensive tests (13 test cases)

**MirBuilder 統合**:
- Added comp_ctx: CompilationContext field
- Marked 15 legacy fields as #[deprecated]
- CompilationContext::with_plugin_sigs() initialization

**テスト結果**:
- ✅ cargo build --release (469 warnings - deprecated)
- ✅ cargo test --release --lib (1029/1033 PASS)
- ✅ phase135_trim_mir_verify.sh (PASS)

**影響範囲**:
- 12 files use comp_ctx fields (87 total usages)
- 36 deprecated fields in builder.rs (ready for Phase 2 cleanup)

**Phase 136 Status**: ✅ 7/7 Context Boxes Complete!
- TypeContext, CoreContext, ScopeContext (Steps 1-3)
- BindingContext, VariableContext, MetadataContext (Steps 4-6)
- CompilationContext (Step 7) - NOW COMPLETE

**Next Phase**: Legacy field deletion (Phase 2)
- Remove #[deprecated] fields from builder.rs
- Migrate all code to ctx accessors
- Reduce deprecation warnings from 469 → 0

903ab8ef4c refactor(mir): Extract MetadataContext from MirBuilder (Phase 136 follow-up 6/7) 
## Summary
Extracted metadata and debug information management into dedicated
MetadataContext struct, completing step 6 of 7 in the Context Box
refactoring plan.

## Changes

- Modified: src/mir/hints.rs (added Clone + Debug derives to HintSink)
- Updated: phase-136-context-box-progress.md (6/7 progress)

## Extracted Fields
- current_span: Span → metadata_ctx.current_span
- source_file: Option<String> → metadata_ctx.source_file
- hint_sink: HintSink → metadata_ctx.hint_sink
- current_region_stack: Vec<RegionId> → metadata_ctx.current_region_stack

## Key Features
- Zero-cost type inference hints (HintSink)

## Tests
- cargo test --release --lib: 1019/1023 passed (4 pre-existing failures)
- phase135_trim_mir_verify.sh: PASS
- Backward compatibility: 100% maintained (deprecated fields synced)

## Progress
Phase 136 Context Extraction: 6/7 complete (86%)
- ✅ Step 1: TypeContext
- ✅ Step 2: CoreContext
- ✅ Step 3: ScopeContext
- ✅ Step 4: BindingContext
- ✅ Step 5: VariableContext
- ✅ Step 6: MetadataContext (this commit)

ee2915a6b2 refactor(mir): Extract VariableContext from MirBuilder (Phase 136 follow-up 5/7) 
## Summary
Extracted variable mapping management into dedicated VariableContext struct,
completing step 5 of 7 in the Context Box refactoring plan.

## Changes
- NEW: src/mir/builder/variable_context.rs (VariableContext struct + helpers)
- Modified: src/mir/builder.rs (added variable_ctx field + sync helpers)
- Updated: phase-136-context-box-progress.md (5/7 progress)

## Extracted Fields
- variable_map: BTreeMap<String, ValueId> → variable_ctx.variable_map

## Key Features
- snapshot/restore for if/loop pattern state management
- JoinIR integration: CarrierInfo::from_variable_map()
- ExitLine contract enforcement (carriers in variable_map)
- NYASH_TRACE_VARMAP debug visualization support

## Design Clarity
- BindingContext: String → BindingId (binding identity, survives SSA renaming)
- VariableContext: String → ValueId (current SSA values, block-local)
- Both contexts work together for complete variable management

## Tests
- cargo test --release --lib: 1014/1018 passed (4 pre-existing failures)
- phase135_trim_mir_verify.sh: PASS
- Backward compatibility: 100% maintained (deprecated fields synced)

## Progress
Phase 136 Context Extraction: 5/7 complete (71%)
- ✅ Step 1: TypeContext
- ✅ Step 2: CoreContext
- ✅ Step 3: ScopeContext
- ✅ Step 4: BindingContext
- ✅ Step 5: VariableContext (this commit)
- ⏳ Step 6: MetadataContext
- ⏳ Step 7: CompilationContext

81d79161e4 feat(mir): Phase 136 Step 2/7 - CoreContext extraction complete 
Extract core ID generation fields from MirBuilder to improve organization:
- value_gen: ValueIdGenerator
- block_gen: BasicBlockIdGenerator
- next_binding_id: u32 (Phase 74)
- temp_slot_counter: u32
- debug_join_counter: u32

Implementation:
- Created src/mir/builder/core_context.rs (215 lines)
- Added core_ctx field to MirBuilder as SSOT
- Deprecated legacy fields with backward compat
- ID allocation methods use core_ctx and sync legacy fields
- Added next_block_id() helper, replaced 30+ block_gen.next() calls

Testing:
- cargo build --release: SUCCESS (193 warnings expected)
- cargo test --release --lib: 1004/1004 PASS (+7 tests)
- phase135_trim_mir_verify.sh: PASS
- phase132_exit_phi_parity.sh: 3/3 PASS

Progress: 2/7 Context extractions complete (TypeContext + CoreContext)

  - Document design principles
  - Plan next steps (CoreContext)

## Impact
- 16 files with 113 deprecated field usages
- No breaking changes (gradual migration)
- All tests pass (997/997)

## Test Results
✅ cargo build --release (warnings only)
✅ cargo test --release --lib (997 passed)
✅ phase135_trim_mir_verify.sh (PASS)
✅ phase132_exit_phi_parity.sh (3/3 PASS)
