5709026812 docs(phase131): Phase 131-3 完了 - LLVM lowering 棚卸し（3ケース） 
Phase 131-3 完了: MIR→LLVM lowering 棚卸し

テスト結果マトリックス:
- Case A (phase87_llvm_exe_min.hako): ✅ PASS (baseline)
- Case B (loop_min_while.hako): ❌ TAG-EMIT (PHI after terminator)
- Case B2 (print(42) simple): ✅ PASS (BoxCall works)
- Case C (llvm_stage3_loop_only.hako): ❌ TAG-EMIT (JoinIR pattern gap)

Critical Bugs:
1. Bug #1: PHI After Terminator (Case B)
   - 原因: function_lower.py が terminator を PHI より先に emit
   - 修正: 4-pass block emission (2-3h)

2. Bug #2: JoinIR Pattern Gap (Case C)
   - 原因: loop(true) { break } パターンが JoinIR 未対応
   - 修正: Pattern 5 設計・実装 (3-4h)

Next Actions:
- P1 (推奨): PHI ordering 修正 → 80% のループを有効化
- P2: JoinIR Pattern 5 → infinite loop 対応

ドキュメント:
- phase131-3-llvm-lowering-inventory.md: 詳細棚卸し結果
- phase87-selfhost-llvm-exe-line.md: LLVM IR parsing error 追記
- CURRENT_TASK.md: phase131-3 参照追加

e912ef9134 docs(phase131): SSOT整備 - VM入口/env var/次の入口を1箇所に固定 
Phase 131 SSOT 整備完了:

1) VM Box 解決の入口SSOT（phase131-2-box-resolution-map.md）
   - 📍 入口3行を先頭に追記（handle_new_box/UnifiedRegistry/BoxFactoryRegistry）
   - NYASH_VM_FAST を bench/profile-only 特例と明記

2) 環境変数のSSOTを1箇所へ（environment-variables.md）
   - ## LLVM Build Pipeline セクション新設（14変数）
   - phase87 の Environment Variables セクションを参照リンクに置き換え
   - 重複表を削除、SSOTドキュメントへの導線確立

3) 次の開発の入口を明確化（CURRENT_TASK.md）
   - P1（Loop Canonicalizer）: 🔶 設計待ち（外部検討中）
   - P2（JoinIR / Selfhost depth-2）: ✅ 実装可能
   - 次に触るSSOTを1行で指定:
     - Loop系: joinir-architecture-overview.md
     - VM Box系: phase131-2-box-resolution-map.md

Impact:
- 迷子防止: 各領域のSSOTが1行で分かる
- 重複削減: env var 表を environment-variables.md に集約
- 状態明確化: P1/P2 の「設計待ち/実装可能」が一目瞭然

cd12a2569e feat(llvm): Phase 87 - LLVM exe line SSOT + integration smoke 
Established single pipeline for .hako → executable generation.

SSOT: tools/build_llvm.sh
- Standard procedure: build_llvm.sh input.hako -o output_exe
- Prerequisites: llvm-config-18, llvmlite, LLVM features enabled
- Pipeline: .hako → MIR → LLVM IR → .o → executable

New files:
- docs: phase87-selfhost-llvm-exe-line.md (SSOT procedure doc)
  * Full troubleshooting guide (llvm-config, llvmlite, linking)
  * Advanced usage (custom output, debugging, performance notes)
  * Anti-patterns documentation (no duplication/fragmentation)
- fixture: apps/tests/phase87_llvm_exe_min.hako (5 lines, return 42)
- smoke: integration/apps/phase87_llvm_exe_min.sh
  * Exit code verification (stdout-independent testing)
  * SKIP if LLVM unavailable (graceful degradation)
  * Integration profile only (not in quick)
- index: 10-Now.md, 01-JoinIR-Selfhost-INDEX.md (Phase 87 entries)
- task: CURRENT_TASK.md (Phase 74-87 status update)

Integration smoke: demonstrates full pipeline

b7f7882558 feat(joinir): Phase 79 Activation - BindingId wiring operational (dev-only) 
Phase 79 の最終段階：BindingId を ExprLowerer に配線し、end-to-end で動作確認。

Key changes:
- ExprLowerer wiring:
  - scope_resolution.rs: build_condition_env_from_scope_with_binding() (BindingId-aware)
  - expr_lowerer.rs: lower_condition() uses BindingId priority lookup

- ConditionEnv extension:
  - register_loop_var_binding(): Loop var BindingId→ValueId registration
  - register_condition_binding(): Condition-only carrier BindingId→ValueId registration

- Pattern2 integration:
  - pattern2_with_break.rs: Loop var registration (Line 116-128)
  - pattern2_with_break.rs: Carrier role-based registration (Line 381-425)
  - Debug logging: [phase79] tags for registration, [binding_pilot/hit] for lookup success

- E2E tests (normalized_joinir_min.rs, debug-only):
  - test_phase79_digitpos_bindingid_lookup_works(): DigitPos pattern verification
  - test_phase79_trim_bindingid_lookup_works(): Trim pattern verification

Result: BindingId lookup actually works end-to-end
- Promoted carriers resolve via BindingId, not string hacks
- Debug: NYASH_JOINIR_DEBUG=1 shows [phase79] Registered loop var BindingId, [binding_pilot/hit] BindingId(1) -> ValueId(100)

Tests: 1025/1025 lib PASS
Design: dev-only feature-gated, dual-path maintained (BindingId priority + name fallback)

Phase 74-79 complete: BindingId migration fully operational
- Infrastructure (74-76): BindingId type, binding_map, 3-tier lookup, promoted_bindings map
- Implementation (77): DigitPos/Trim populate, legacy deprecate
- Refactoring (78-79 Refactoring): PromotedBindingRecorder, Detector/Recorder split
- Activation (80 Foundation + 79 Activation): CarrierBindingAssigner + ExprLowerer wiring

8b48bec962 feat(joinir): Phase 78 - BindingId infrastructure for promoted carriers (dev-only) 
Phase 78 adds infrastructure to assign BindingIds to synthetic promoted
carriers (e.g., is_digit_pos, is_ch_match), enabling type-safe promoted
variable lookup without string-based naming conventions.

Key Changes:
1. CarrierVar.binding_id field (dev-only):
   - Added Option<BindingId> to track BindingId for each carrier
   - Updated all constructors and struct instantiations

2. CarrierBindingAssigner Box (new file, 273 lines):
   - Allocates BindingIds for promoted carriers via builder.allocate_binding_id()
   - Records original → promoted mapping in promoted_bindings
   - Sets binding_id field on promoted CarrierVar
   - Includes 3 comprehensive unit tests

3. ConditionEnv.register_carrier_binding() (new method):
   - Registers carrier BindingId → ValueId mappings
   - Enables type-safe lookup via binding_id_map

4. Logging cleanup:
   - Gated 6 eprintln! statements with NYASH_JOINIR_DEBUG
   - Unified logging tags to [binding_pilot/*]

Design Decisions:
- Promoters create CarrierInfo, lowering code assigns BindingIds
- CarrierBindingAssigner called from Pattern2/4 lowering (has builder access)
- Clear documentation prevents misuse (promoters lack builder access)

Files modified (18):
- carrier_info.rs: binding_id field added to CarrierVar
- carrier_binding_assigner.rs: New Box for BindingId allocation
- condition_env.rs: register_carrier_binding() method
- mod.rs: Module exports
- pattern2_with_break.rs, pattern4_with_continue.rs: Updated for binding_id
- loop_body_*_promoter.rs: Logging cleanup + binding_id in structs
- phase78-bindingid-promoted-carriers.md: Architecture documentation

Tests: 970/970 PASS (zero regressions)
Status: Infrastructure complete, integration deferred to Phase 79

Next Phase: Wire CarrierBindingAssigner in Pattern2/4 lowering + E2E tests

851bf4f8a5 design(joinir): Phase 73 - ScopeManager BindingId Migration Design + PoC 
Phase 73 plans migration from name-based to BindingId-based scope management
in JoinIR lowering, aligning with MIR's lexical scope model.

Design decision: Option A (Parallel BindingId Layer) with gradual migration.
Migration roadmap: Phases 74-77, ~8-12 hours total, zero production impact.

Changes:
- phase73-scope-manager-design.md: SSOT design (~700 lines)
- phase73-completion-summary.md: Deliverables summary
- phase73-index.md: Navigation index
- scope_manager_bindingid_poc/: Working PoC (437 lines, dev-only)

Tests: 6/6 PoC tests PASS, lib 950/950 PASS
Implementation: Parallel layer (no changes to existing code paths)
