d7805e5974 feat(joinir): Phase 213-2 Step 2-2 & 2-3 Data structure extensions 
Extended PatternPipelineContext and CarrierUpdateInfo for Pattern 3 AST-based generalization.

Changes:
1. PatternPipelineContext:
   - Added loop_condition: Option<ASTNode>
   - Added loop_body: Option<Vec<ASTNode>>
   - Added loop_update_summary: Option<LoopUpdateSummary>
   - Updated build_pattern_context() for Pattern 3

2. CarrierUpdateInfo:
   - Added then_expr: Option<ASTNode>
   - Added else_expr: Option<ASTNode>
   - Updated analyze_loop_updates() with None defaults

Status: Phase 213-2 Steps 2-2 & 2-3 complete

120fbdb523 fix(mir): Receiver used_values for DCE + trace + cleanup 
- Fix: Call with Callee::Method now includes receiver in used_values()
  - Prevents DCE from eliminating Copy instructions that define receivers
  - Pattern 3 (loop_if_phi.hako) now works correctly (sum=9)

- Add: NYASH_DCE_TRACE=1 for debugging eliminated instructions
  - Shows which pure instructions DCE removes and from which block

- Cleanup: Consolidate Call used_values to single source of truth
  - Early return in methods.rs handles all Call variants
  - Removed duplicate match arm (now unreachable!())
  - ChatGPT's suggestion for cleaner architecture

- Docs: Phase 166 analysis of inst_meta layer architecture
  - Identified CSE pass callee bug (to be fixed next)
  - Improvement proposals for CallLikeInst

caf38dba19 feat(joinir): Phase 190 - LoopExitBinding boxification 
Formalize exit PHI → variable_map reconnection with explicit LoopExitBinding
structure. Eliminates hardcoded variable names and prepares for Pattern 4+
multi-carrier support.

Key changes:

1. **New LoopExitBinding struct**:
   - carrier_name: String (e.g., "sum", "count")
   - join_exit_value: ValueId (JoinIR exit value)
   - host_slot: ValueId (variable_map destination)
   Makes it explicit: WHICH variable, FROM where, TO where.

2. **Updated JoinInlineBoundary**:
   - Replaced implicit host_outputs: Vec<ValueId>
   - With explicit exit_bindings: Vec<LoopExitBinding>
   - Old APIs marked #[deprecated] for backward compatibility

3. **Pattern 3 now uses explicit bindings**:
   Before: boundary.host_outputs = vec![sum_var_id]  // implicit
   After:  boundary.exit_bindings = vec![LoopExitBinding {
       carrier_name: "sum".to_string(),
       join_exit_value: ValueId(18),
       host_slot: sum_var_id,
   }]

4. **merge_joinir_mir_blocks() updated**:
   - Consumes exit_bindings instead of bare ValueIds
   - Enhanced debug output shows carrier names
   - Validates carrier name matches variable_map expectations

Benefits:
- Self-documenting code: bindings explain themselves
- Multi-carrier ready: Pattern 4+ just extend the vec![]
- Type-safe: No implicit semantics
- Debuggable: Explicit carrier name in logs

Test status:
- Build: ✅ SUCCESS (0 errors, 47 warnings)
- Pattern 3: ✅ PASS (no regressions)
- Backward compatibility: ✅ Maintained via #[deprecated]

Prepare for Phase 191: Pattern Router Table and Phase 192: JoinLoopTrace

3e3d1b369d refactor(phase124): Delete NYASH_HAKO_CHECK_JOINIR flag completely 
- Remove src/config/env/hako_check.rs entirely (file deleted)
- Comment out hako_check module in src/config/env.rs with Phase 124 markers
- Mark NYASH_HAKO_CHECK_JOINIR as deleted in environment-variables.md
- Document reason: JoinIR-only consolidation makes flag unnecessary

Phase 124 Task 2/5 complete

adc10fdf54 Phase 123 proper完了：hako_check JoinIR実装（環境変数選択可能化） 
## 実装内容

### 1. 環境変数フラグ追加
- NYASH_HAKO_CHECK_JOINIR でJoinIR/Legacy経路を切り替え可能
- src/config/env/hako_check.rs で hako_check_joinir_enabled() 実装
- デフォルト: false（レガシー経路）で後方互換性確保

### 2. MIR Builder JoinIR スイッチ
- cf_if() メソッドにフラグチェック追加
- try_cf_if_joinir() プレースホルダー実装（Phase 124で完全実装）
- JoinIR → legacy フォールバック機構を構築

### 3. テストケース作成（4個）
- phase123_simple_if.hako
- phase123_nested_if.hako
- phase123_while_loop.hako
- phase123_if_in_loop.hako

### 4. テスト結果
✅ Legacy path: 4/4 PASS
✅ JoinIR path: 4/4 PASS
（JoinIR path は現在フォールバック経由で動作）

### 5. ドキュメント更新
- environment-variables.md: NYASH_HAKO_CHECK_JOINIR 記載
- phase121_hako_check_joinir_design.md: Phase 123実装セクション追加
- hako_check_design.md: 2パス実行フロー図を追加
- CURRENT_TASK.md: Phase 123完了を記録

## 数値成果

- 新規ファイル: 2個 (config/env/hako_check.rs, test cases × 4, test script)
- 修正ファイル: 6個
- 総追加行数: 335行
- ビルド: Zero errors

## 設計・実装の特徴

✅ Environment variable で簡単に経路切り替え可能
✅ レガシー経路を完全に保持（後方互換性）
✅ JoinIR基盤を Phase 124 での完全実装に向けて構築
✅ フォールバック機構でリスク最小化

## 次のステップ

Phase 124: JoinIR 完全実装＆デフォルト化
- try_cf_if_joinir() を IfSelectLowerer と統合
- Loop JoinIR 統合追加
- JoinIR をデフォルト経路に変更
- NYASH_LEGACY_PHI=1 で legacy フォールバック可能に

Tests:
- 3/3 unit tests pass (test_select_true/false/int_cond)
- Integration tests pass (RC: 0)
- A/B execution verified (existing if_phi vs JoinIR Select)

Files changed:
- New: apps/tests/joinir_if_select_{simple,local}.hako
- New: src/mir/join_ir/lowering/if_select.rs
- Modified: src/mir/join_ir/{mod,json,runner,vm_bridge}.rs
- Modified: src/config/env.rs (joinir_if_select_enabled)
- Modified: docs/reference/environment-variables.md

Phase 33-3 ready: MIR pattern recognition + auto-lowering pending

94b2bd2799 feat(selfhost): add observation logs for Ny compiler path diagnosis 
Add NYASH_CLI_VERBOSE>=2 observation logs to trace the Ny compiler
child process path (NYASH_USE_NY_COMPILER=1):
- Log when spawning child process
- Log when receiving Program(JSON v0)
- Log before/after maybe_dump_mir with dump path info
- Report whether MIR dump file was created

Key finding: apps/selfhost/compiler/compiler.hako doesn't exist,
so the preferred child process route never fires. This explains
why RUST_MIR_DUMP_PATH doesn't create files in Ny compiler path.

Also update environment-variables.md with:
- NYASH_CLI_VERBOSE=2 level documentation
- Ny compiler observation template for Phase 29
