d2972c1437 feat(joinir): Phase 92完了 - ConditionalStep + body-local変数サポート 
## Phase 92全体の成果

**Phase 92 P0-P2**: ConditionalStep JoinIR生成とbody-local変数サポート
- ConditionalStep（条件付きキャリア更新）のJoinIR生成実装
- Body-local変数（ch等）の条件式での参照サポート
- 変数解決優先度: ConditionEnv → LoopBodyLocalEnv

**Phase 92 P3**: BodyLocalPolicyBox + 安全ガード
- BodyLocalPolicyDecision実装（Accept/Reject判定）
- BodyLocalSlot + DualValueRewriter（JoinIR/MIR二重書き込み）
- Fail-Fast契約（Cannot promote LoopBodyLocal検出）

**Phase 92 P4**: E2E固定＋回帰最小化 (本コミット)
- Unit test 3本追加（body-local変数解決検証）
- Integration smoke追加（phase92_pattern2_baseline.sh、2ケースPASS）
- P4-E2E-PLAN.md、P4-COMPLETION.md作成

## 主要な実装

### ConditionalStep（条件付きキャリア更新）
- `conditional_step_emitter.rs`: JoinIR Select命令生成
- `loop_with_break_minimal.rs`: ConditionalStep検出と統合
- `loop_with_continue_minimal.rs`: Pattern4対応

### Body-local変数サポート
- `condition_lowerer.rs`: body-local変数解決機能
  - `lower_condition_to_joinir`: body_local_env パラメータ追加
  - 変数解決優先度実装（ConditionEnv優先）
  - Unit test 3本追加: 変数解決/優先度/エラー
- `header_break_lowering.rs`: break条件でbody-local変数参照
- 7ファイルで後方互換ラッパー（lower_condition_to_joinir_no_body_locals）

### Body-local Policy & Safety
- `body_local_policy.rs`: BodyLocalPolicyDecision（Accept/Reject）
- `body_local_slot.rs`: JoinIR/MIR二重書き込み
- `dual_value_rewriter.rs`: ValueId書き換えヘルパー

## テスト体制

### Unit Tests (+3)
- `test_body_local_variable_resolution`: body-local変数解決
- `test_variable_resolution_priority`: 変数解決優先度（ConditionEnv優先）
- `test_undefined_variable_error`: 未定義変数エラー
- 全7テストPASS（cargo test --release condition_lowerer::tests）

### Integration Smoke (+1)
- `phase92_pattern2_baseline.sh`:
  - Case A: loop_min_while.hako (Pattern2 baseline)
  - Case B: phase92_conditional_step_minimal.hako (条件付きインクリメント)
  - 両ケースPASS、integration profileで発見可能

### 退行確認
- ✅ 既存Pattern2Breakテスト正常（退行なし）
- ✅ Phase 135 smoke正常（MIR検証PASS）

## アーキテクチャ設計

### 変数解決メカニズム
```rust
// Priority 1: ConditionEnv (loop params, captured)
if let Some(value_id) = env.get(name) { return Ok(value_id); }
// Priority 2: LoopBodyLocalEnv (body-local like `ch`)
if let Some(body_env) = body_local_env {
    if let Some(value_id) = body_env.get(name) { return Ok(value_id); }
}
```

### Fail-Fast契約
- Delta equality check (conditional_step_emitter.rs)
- Variable resolution error messages (ConditionEnv)
- Body-local promotion rejection (BodyLocalPolicyDecision::Reject)

## ドキュメント

- `P4-E2E-PLAN.md`: 3レベルテスト戦略（Level 1-2完了、Level 3延期）
- `P4-COMPLETION.md`: Phase 92完了報告
- `README.md`: Phase 92全体のまとめ

## 将来の拡張（Phase 92スコープ外）

- Body-local promotionシステム拡張
- P5bパターン認識の汎化（flagベース条件サポート）
- 完全なP5b E2Eテスト（body-local promotion実装後）

9e3b258046 feat(phase-91): JoinIR Selfhost depth-2 advancement - Pattern P5b design & planning 
## Overview
Analyzed 34 loops across selfhost codebase to identify JoinIR coverage gaps.
Current readiness: 47% (16/30 loops). Next frontier: Pattern P5b (Escape Handling).

## Current Status
- Phase 91 planning document: Complete
  - Loop inventory across 6 key files
  - Priority ranking: P5b (escape) > P5 (guard) > P6 (nested)
  - Effort estimates and ROI analysis

- Pattern P5b Design: Complete
  - Problem statement (variable-step carriers)
  - Pattern definition with Skeleton layout
  - Recognition algorithm (8-step detection)
  - Capability taxonomy (P5b-specific guards)
  - Lowering strategy (Phase 92 preview)

- Test fixture: Created
  - Minimal escape sequence parser
  - JSON string with backslash escape

- Loop Canonicalizer extended
  - Capability table updated with P5b entries
  - Fail-Fast criteria documented
  - Implementation checklist added

## Key Findings

### Loop Readiness Matrix
| Category | Count | JoinIR Status |
|----------|-------|--------------|
| Pattern 1 (simple bounded) | 16 | ✅ Ready |
| Pattern 2 (with break) | 1 | ⚠️ Partial |
| **Pattern P5b (escape seq)** | ~3 | ❌ NEW |
| Pattern P5 (guard-bounded) | ~2 | ❌ Deferred |
| Pattern P6 (nested loops) | ~8 | ❌ Deferred |

### Top Candidates
1. **P5b**: json_loader.hako:30 (8 lines, high reuse)
   - Effort: 2-3 days (recognition)
   - Impact: Unlocks all escape parsers

2. **P5**: mini_vm_core.hako:541 (204 lines, monolithic)
   - Effort: 1-2 weeks
   - Impact: Major JSON optimization

3. **P6**: seam_inspector.hako:76 (7+ nesting)
   - Effort: 2-3 weeks
   - Impact: Demonstrates nested composition

## Phase 91 Strategy
**Recognition-only phase** (no lowering in P1):
- Step 1: Design & planning ✅
- Step 2: Canonicalizer implementation (detect_escape_pattern)
- Step 3: Unit tests + parity verification
- Step 4: Lowering deferred to Phase 92

## Files Added
- docs/development/current/main/phases/phase-91/README.md - Full analysis & planning
- docs/development/current/main/design/pattern-p5b-escape-design.md - Technical design
- tools/selfhost/test_pattern5b_escape_minimal.hako - Test fixture

## Files Modified
- docs/development/current/main/design/loop-canonicalizer.md
  - Capability table extended with P5b entries
  - Pattern P5b full section added
  - Implementation checklist updated

## Acceptance Criteria (Phase 91 Step 1)
- ✅ Loop inventory complete (34 loops across 6 files)
- ✅ Pattern P5b design document ready
- ✅ Test fixture created
- ✅ Capability taxonomy extended
- ⏳ Implementation deferred (Step 2+)

## References
- JoinIR Architecture: joinir-architecture-overview.md
- Phase 91 Plan: phases/phase-91/README.md
- P5b Design: design/pattern-p5b-escape-design.md

Next: Implement detect_escape_pattern() recognition in Phase 91 Step 2

22b0c14adb feat(joinir): Phase 135 P1 - Contract checks Fail-Fast (二度と破れない設計) 
## Summary
Adds early Fail-Fast contract verification to prevent Phase 135 P0 issues from recurring.
Two new verifiers catch allocator SSOT violations and boundary inconsistencies before --verify.

## Changes

### Step 1: verify_condition_bindings_consistent
**Location**: `src/mir/builder/control_flow/joinir/merge/contract_checks.rs`

**Contract**: condition_bindings can have aliases (multiple names for same join_value),
but same join_value with different host_value is a violation.

**Example Error**:
```
[JoinIRVerifier/Phase135-P1] condition_bindings conflict:
  join_value ValueId(104) mapped to both ValueId(12) and ValueId(18)
```

**Catches**: ConditionLoweringBox bypassing SSOT allocator before BoundaryInjector

### Step 2: verify_header_phi_dsts_not_redefined
**Location**: `src/mir/builder/control_flow/joinir/merge/contract_checks.rs`

**Contract**: Loop header PHI dst ValueIds must not be reused as dst in non-PHI instructions.
Violation breaks MIR SSA (PHI dst overwrite).

**Example Error**:
```
[JoinIRVerifier/Phase135-P1] Header PHI dst ValueId(14) redefined by non-PHI instruction in block 3:
  Instruction: Call { dst: Some(ValueId(14)), ... }
```

**Catches**: ValueId collisions between header PHI dsts and lowered instructions

### Integration
**Location**: `src/mir/builder/control_flow/joinir/merge/mod.rs`

Added to `verify_joinir_contracts()`:
1. Step 1 runs before merge (validates boundary)
2. Step 2 runs after merge (validates func with PHI dst set)

### Documentation
- Updated `phase135_trim_mir_verify.sh` - Added P1 contract_checks description
- Updated `phase-135/README.md` - Added P1 section with contract details and effects

## Acceptance
✅ Build: SUCCESS
✅ Smoke: phase135_trim_mir_verify.sh - PASS
✅ Regression: phase132_exit_phi_parity.sh - 3/3 PASS
✅ Regression: phase133_json_skip_whitespace_llvm_exe.sh - PASS

## Effect
- **Prevention**: Future Box implementations catch SSOT violations immediately
- **Explicit Errors**: Phase 135-specific messages instead of generic --verify failures
- **Unbreakable**: Debug builds always detect violations, enforced by CI/CD

d82c332a40 feat(joinir): Phase 135 P0 - ConditionLoweringBox allocator SSOT (ValueId collision fix) 
## Summary
Root cause: ConditionLoweringBox was bypassing ConditionContext.alloc_value (SSOT allocator),
causing ValueId collisions between JoinIR condition params and lowered instructions.

## Changes
1. **ConditionLoweringBox (expr_lowerer.rs)**: Must use ConditionContext.alloc_value
   - Pass &mut ConditionContext to lower_condition (SSOT allocator)
   - Eliminates internal counter usage

2. **Allocator unification (condition_lowerer.rs, method_call_lowerer.rs)**:
   - Accept &mut dyn FnMut() -> ValueId as allocator parameter
   - Ensures all lowering paths use same SSOT allocator

3. **Boundary Copy deduplication (joinir_inline_boundary_injector.rs)**:
   - Deduplicate condition_bindings by dst
   - Fail-Fast if different sources target same dst (MIR SSA violation)

4. **Trim pattern fixes (trim_loop_lowering.rs, trim_pattern_validator.rs, stmts.rs)**:
   - Use builder.next_value_id() instead of value_gen.next() in function context
   - Ensures function-level ValueId allocation respects reserved PHI dsts

## Acceptance
✅ ./target/release/hakorune --verify apps/tests/phase133_json_skip_whitespace_min.hako
✅ Smoke: phase135_trim_mir_verify.sh - MIR SSA validation PASS
✅ Regression: phase132_exit_phi_parity.sh - 3/3 PASS
✅ Regression: phase133_json_skip_whitespace_llvm_exe.sh - compile-only PASS

aad01a1079 feat(llvm): Phase 132-P2 - Dict ctx removal (FunctionLowerContext SSOT completion) 
Completed SSOT unification for FunctionLowerContext by removing the manual
dict ctx creation and assignment in function_lower.py.

Changes:
- Removed builder.ctx = dict(...) creation (18 lines, lines 313-330)
- Removed builder.resolver.ctx assignment (no longer needed)
- Confirmed instruction_lower.py uses context=owner.context throughout
- Added phase132_multifunc_isolation_min.hako test for multi-function isolation
- Extended phase132_exit_phi_parity.sh with Case C (Rust VM context test)

Testing:
- Phase 132 smoke test: All 3 cases PASS
- Phase 87 LLVM exe test: PASS (Result: 42)
- STRICT mode: PASS
- No regressions: Behavior identical before/after (RC:6 maintained)

Impact:
- Reduced manual context management complexity
- FunctionLowerContext now sole source of truth (SSOT)
- Per-function state properly isolated, no cross-function collisions
- Cleaner architecture: context parameter passed explicitly vs manual dict

42f7eaa215 tools: speed up build_llvm NyRT cache + fix Phase 132 smoke counters 
Improvements:
1. NyRT build cache in tools/build_llvm.sh
   - Skip [3/4] rebuild when target/release/libnyash_kernel.a exists
   - Add NYASH_LLVM_FORCE_NYRT_BUILD env var to force rebuild
   - Performance: 60-80% faster on incremental builds

2. Fix Phase 132 smoke test arithmetic bug
   - Replace ((PASS_COUNT++)) with PASS_COUNT=$((PASS_COUNT + 1))
   - Issue: ((x++)) returns 0 when x=0, causes set -e to exit
   - Locations: 8 places in phase132_exit_phi_parity.sh

3. Document NYASH_LLVM_FORCE_NYRT_BUILD in environment-variables.md

Acceptance criteria met:
- Behavior unchanged (first build creates .a, subsequent skip rebuild)
- NYASH_LLVM_FORCE_NYRT_BUILD allows forcing rebuild
- Phase 132 smoke test passes (both cases)
- Behavior-preserving optimization

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
- Build: .hako → .o → exe (successful ✅)
- Runtime: Ring0 initialization issue (known limitation, out of scope)
Quick profile: unchanged (integration only, per policy)
Policy: No duplicate build paths, SSOT maintained

987/987 tests PASS (production stable)

e30116f53d feat(joinir): Phase 171-fix ConditionEnv/ConditionBinding architecture 
Proper HOST↔JoinIR ValueId separation for condition variables:

- Add ConditionEnv struct (name → JoinIR-local ValueId mapping)
- Add ConditionBinding struct (HOST/JoinIR ValueId pairs)
- Modify condition_to_joinir to use ConditionEnv instead of builder.variable_map
- Update Pattern2 lowerer to build ConditionEnv and ConditionBindings
- Extend JoinInlineBoundary with condition_bindings field
- Update BoundaryInjector to inject Copy instructions for condition variables

This fixes the undefined ValueId errors where HOST ValueIds were being
used directly in JoinIR instructions. Programs now execute (RC: 0),
though loop variable exit values still need Phase 172 work.

Key invariants established:
1. JoinIR uses ONLY JoinIR-local ValueIds
2. HOST↔JoinIR bridging is ONLY through JoinInlineBoundary
3. condition_to_joinir NEVER accesses builder.variable_map

5bc0fa861f feat(joinir): Phase 188 Pattern 1 Core Implementation + Phase 189 Planning 
Phase 188 Status: Planning & Foundation Complete (100%)

Completed Tasks:
✅ Task 188-1: Error Inventory (5 patterns identified)
✅ Task 188-2: Pattern Classification (3 patterns selected)
✅ Task 188-3: Design (51KB comprehensive blueprint)
✅ Task 188-4: Implementation Foundation (1,802 lines scaffolding)
✅ Task 188-5: Verification & Documentation
✅ Pattern 1 Core Implementation: Detection + Lowering + Routing

Pattern 1 Implementation (322 lines):
- Pattern Detection: is_simple_while_pattern() in loop_pattern_detection.rs
- JoinIR Lowering: lower_simple_while_to_joinir() in simple_while_minimal.rs (219 lines)
  - Generates 3 functions: entry, loop_step (tail-recursive), k_exit
  - Implements condition negation: exit_cond = !(i < 3)
  - Tail-recursive Call pattern with state propagation
- Routing: Added "main" to function routing list in control_flow.rs
- Build: ✅ SUCCESS (0 errors, 34 warnings)

Infrastructure Blocker Identified:
- merge_joinir_mir_blocks() only handles single-function JoinIR modules
- Pattern 1 generates 3 functions (entry + loop_step + k_exit)
- Current implementation only merges first function → loop body never executes
- Root cause: control_flow.rs line ~850 takes only .next() function

Phase 189 Planning Complete:
- Goal: Refactor merge_joinir_mir_blocks() for multi-function support
- Strategy: Sequential Merge (Option A) - merge all functions in call order
- Effort estimate: 5.5-7.5 hours
- Deliverables: README.md (16KB), current-analysis.md (15KB), QUICKSTART.md (5.8KB)

9f2c791f2a fix(json_parser): Eliminate _parse_number() infinite loop with flat control flow 
Root cause: Nested-if-in-loop pattern triggered MIR compiler bug
- `if parsing_done == 1 { break }` inside loop caused infinite execution
- Flag variable approach created 2-level nesting that MIR couldn't handle

Fix: Refactored to flat control flow
- Removed `parsing_done` flag variable
- Inverted condition: check exit first (`digit_pos < 0 → break`)
- Direct break without nesting
- Moved `digits` constant outside loop (optimization)

Result:
- Lines: 28 → 15 (-46% complexity)
- Nesting: 2 levels → 1 level
- MIR-safe: No nested-if-in-loop pattern

This unblocks Phase 161-2 full MIR JSON parsing (rep1_if_simple.mir.json 8.5KB)

3c6797c1fb feat(phase161): Add MirAnalyzerBox implementation (Phase 161-2 基本実装) 
Task先生による Phase 161-2 実装成果:

**tools/hako_shared/mir_analyzer.hako** (375行)
- MirAnalyzerBox: MIR JSON v1 パーサー＆アナライザー
- Core Methods:
  - birth(mirJsonText): JSON パース＆キャッシュ
  - validateSchema(): MIR v1 構造検証
  - summarize_function(funcIndex): メタデータ抽出
  - count_phis(funcIndex): PHI 命令検出
  - count_loops(funcIndex): CFG backward edge によるループ検出

**テストインフラ**
- test_mir_analyzer.hako: テストハーネスフレームワーク
- test_rep1_inline.hako: インラインテスト (rep1_if_simple)
- rep1_if_simple.mir.json: MIR JSON テストデータ (8.5KB)
- rep2_loop_simple.mir.json: ループパターンテストデータ (9.6KB)

**箱理論適用**
- 箱化: MirAnalyzerBox = MIR 分析専任（単一責務）
- 境界: JsonParserBox との完全分離
- Fail-Fast: 明示的エラー、フォールバック無し
- 遅延SG: _functions キャッシュ、オンデマンド計算

**発見された課題**
- JsonParserBox._parse_number() 無限ループ問題（次タスクで対処）
- VM ステップ予算超過でフル MIR JSON テスト一時ブロック

Status: Phase 161-2 80%完了（コア実装OK、テスト検証はJsonParser修正後）
Next: _parse_number() 修正 → Phase 161-2 テスト完了 → Phase 161-3

dd314a0a72 feat(hako_check): Improve usability with debug output filtering 
Phase 1 実装: デバッグ出力ノイズを除去して、実際の lint 結果を見やすく

改善内容:
1. デバッグ出力の自動フィルタリング (デフォルト有効)
   - [DEBUG/...] 系の出力を全て除去
   - [ControlForm::...] 制御フロー出力を除去
   - [BUILDER] MIR ビルダー出力を除去
   - [rule/exec] ルール実行出力を除去

2. 環境変数サポート追加
   - HAKO_CHECK_DEBUG=1 で詳細デバッグ出力有効化
   - HAKO_CHECK_VERBOSE=1 で詳細モード有効化（将来実装予定）

3. 実際の エラーメッセージが明確に見える
   - 修正前: 大量の [DEBUG] 出力に埋もれて見えない
   - 修正後: [ERROR] メッセージが直接見える

実行例:
```bash
# デフォルト: クリーンな出力
./tools/hako_check.sh file.hako
[ERROR] ❌ MIR compilation error: Undefined variable: void
[lint/summary] failures: 1

# デバッグモード: 詳細情報表示
HAKO_CHECK_DEBUG=1 ./tools/hako_check.sh file.hako
[DEBUG/build_block] Processing 3 statements
[ControlForm::Loop] entry=BasicBlockId(2) ...
```

次のステップ (Phase 2, 3):
- Rust 側のデバッグ出力環境変数制御化
- エラーメッセージの構造化とヒント表示

c86b6e3baa fix(hako_check): Restore functionality with void-safety guards and option parsing 
重大バグを2つ修正して hako_check をセルフホスティングソースで使えるように:

1. cli.hako の VoidBox.get() エラー修正 (最優先)
   - HakoAnalysisBuilderBox.build_from_source_flags() が void を返す可能性に対応
   - フォールバック処理を追加: null/void チェック → Minimal MapBox 生成
   - 134行の null チェックが不十分だった

2. hako_check.sh の引数処理修正 (中優先)
   - --dead-code, --rules, --no-ast, --debug オプションをサポート
   - 以前は --format のみ処理、他はそのまま sed に渡されていた
   - while ループで全オプションを正しくパース、EXTRA_ARGS に蓄積

3. cli.hako への EXTRA_ARGS 伝播
   - --format "$FORMAT" $EXTRA_ARGS を引数として cli.hako に渡す

結果:
✅ hako_check がセルフホスティングソースで実行可能に
✅ [lint/summary] failures: 1 が出力される（正常動作）
✅ --dead-code オプションが実装済みだが、スクリプトが反映していなかった

次のステップ: デバッグ出力ノイズ削減（デフォルトで [DEBUG/build_block] を非表示）

608693af7f fix(json_parser): Fix infinite loop by working around MIR nested-if bug 
🐛 バグ修正: JsonParserBox 無限ループ解消

**問題**:
- `vm step budget exceeded` エラーが発生
- `_parse_number()` で無限ループ

**根本原因**:
- MIR lowering の既知のバグ: ループ内のネスト if-else 文が無限ジャンプチェーンを生成
- bb11 → bb6 → bb4 の無条件ジャンプループ
- PHI 更新が実行されず、ループ変数が更新されない

**修正内容**:
1. `while` → `loop()` 構文に統一（10箇所）
2. ネスト if-else をフラット化（workaround）:
   - `_parse_number()`: `ch >= "0" && ch <= "9"` → `digits.indexOf(ch) >= 0`
   - `_parse_string()`: ネスト if を分離
   - `_unescape_string()`: `ch == "\\" && i + 1 < s.length()` をフラット化

**テスト**:
- json_parser.hako: RC 0 ✅
- ネスト if-else バグを回避して正常動作

**注記**:
- 根本修正（MIR lowering bug fix）は別タスク
- workaround で Phase 173 ブロック解除

000335c32e feat(hako_check): Phase 154 MIR CFG integration & HC020 dead block detection 
Implements block-level unreachable code detection using MIR CFG information.
Complements Phase 153's method-level HC019 with fine-grained analysis.

Core Infrastructure (Complete):
- CFG Extractor: Extract block reachability from MirModule
- DeadBlockAnalyzerBox: HC020 rule for unreachable blocks
- CLI Integration: --dead-blocks flag and rule execution
- Test Cases: 4 comprehensive patterns (early return, constant false, infinite loop, break)
- Smoke Test: Validation script for all test cases

Implementation Details:
- src/mir/cfg_extractor.rs: New module for CFG→JSON extraction
- tools/hako_check/rules/rule_dead_blocks.hako: HC020 analyzer box
- tools/hako_check/cli.hako: Added --dead-blocks flag and HC020 integration
- apps/tests/hako_check/test_dead_blocks_*.hako: 4 test cases

Architecture:
- Follows Phase 153 boxed modular pattern (DeadCodeAnalyzerBox)
- Optional CFG field in Analysis IR (backward compatible)
- Uses MIR's built-in reachability computation
- Gracefully skips if CFG unavailable

Known Limitation:
- CFG data bridge pending (Phase 155): analysis_consumer.hako needs MIR access
- Current: DeadBlockAnalyzerBox implemented, but CFG not yet in Analysis IR
- Estimated 2-3 hours to complete bridge in Phase 155

Test Coverage:
- Unit tests: cfg_extractor (simple CFG, unreachable blocks)
- Integration tests: 4 test cases ready (will activate with bridge)
- Smoke test: tools/hako_check_deadblocks_smoke.sh

Documentation:
- phase154_mir_cfg_inventory.md: CFG structure investigation
- phase154_implementation_summary.md: Complete implementation guide
- hako_check_design.md: HC020 rule documentation

Next Phase 155:
- Implement CFG data bridge (extract_mir_cfg builtin)
- Update analysis_consumer.hako to call bridge
- Activate HC020 end-to-end testing

e4eedef34f feat(llvm): Phase 132 - Fix PHI instruction ordering bug 
Structural fix for LLVM backend PHI placement issue discovered in Phase 131.

Changes:
- Modified ensure_phi() to position PHI before existing instructions
- Enhanced setup_phi_placeholders() with debug mode
- Created phi_placement.py utility for validation
- Added test script for representative cases

Technical approach:
- PHI creation during setup (before block lowering)
- Explicit positioning with position_before(instrs[0])
- Debug infrastructure via NYASH_PHI_ORDERING_DEBUG=1

Design principles:
- PHI must be created when blocks are empty
- finalize_phis only wires, never creates
- llvmlite API constraints respected

Phase 132 complete. Ready for Phase 133 (ConsoleBox integration).

  - esc_dirname_smoke.hako (複雑制御構造・StringBox)
- ✅ 期待フロー整理: JoinIR Strict モード説明ドキュメント作成
- ✅ 実行調査完了: NYASH_JOINIR_STRICT=1 での動作確認
- ✅ ベースライン確立: 詳細実行結果記録
- ✅ スモークスクリプト作成: integration profileに統合

### 実行結果
- ✅ 完全成功: 2/3 (peek_expr_block, loop_min_while)
- ⚠️ 既知問題: 1/3 (esc_dirname_smoke - ConsoleBox.println解決失敗)

### JoinIR Strict検証結果
- ✅ If Lowering 動作
- ✅ Loop Lowering 動作
- ✅ PHI命令生成
- ✅ ControlForm構造生成
- ✅ StringBox操作
- ❌ ConsoleBox.println (メソッド解決失敗)

### Phase 122+への課題
**高優先度**:
- ConsoleBox.printlnメソッド解決エラー修正

**中優先度**:
- NYASH_PARSER_STAGE3非推奨警告対応

**低優先度**:
- builtin Box プラグイン移行検討

### 技術的成果
- Phase 106-115の安定性確認完了
- JoinIR Lowering動作確認
- 明確なPhase 122+タスクリスト確立
- 回帰検証可能なテスト整備

### ファイル構成
**新規作成**:
- docs/development/current/main/phase120_selfhost_stable_paths.md (指示書)
- docs/development/current/main/selfhost_stage3_expected_flow.md (期待フロー)
- docs/development/current/main/phase120_baseline_results.md (ベースライン結果)
- tools/smokes/v2/profiles/integration/selfhost/phase120_stable_paths.sh (スモークテスト)

**修正**:
- CURRENT_TASK.md (Phase 120完了記録追加)

804ccff23f feat(phase73): Selfhost Stage-B I/O 簡素化 - HAKO_SRC 環境変数統一化 
Unified selfhost Stage-B I/O path from argv to environment variables:
- Remove --source "$SRC_CONTENT" from compiler.hako invocation (argv limit)
- Export HAKO_SRC="$SRC_CONTENT" instead (env-based I/O)
- Update compiler_stageb.hako to check HAKO_SRC fallback

Changes:
1. lang/src/compiler/entry/compiler_stageb.hako:
   - Added HAKO_SRC env check in StageBArgsBox.resolve_src()
   - Fallback order: --source arg → HAKO_SOURCE_FILE_CONTENT → HAKO_SRC → default

2. tools/selfhost/selfhost_build.sh:
   - Removed --source "$SRC_CONTENT" from compiler.hako invocation
   - Export HAKO_SRC="$SRC_CONTENT" before Stage-B execution
   - Unified with wrapper pathway (HAKO_USE_BUILDBOX=1)

Benefits:
- Eliminates "Argument list too long" (os error 7) for large .hako files
- Single unified I/O pattern (env variables) for all Stage-B paths
- Consistent with hako_check.sh and wrapper pattern
- Ready for future HAKO_SRC_FILE optimization

Verification:
✅ NYASH_FEATURES=stage3 NYASH_USE_NY_COMPILER=1 \
  ./tools/selfhost/selfhost_build.sh --in apps/tests/stage1_run_min.hako --run
  Output: abc (correct)
