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）

568619df89 feat(mir): Phase 92 P2-2 - Body-local variable support for ConditionalStep 
Phase 92 P2-2完了：ConditionalStepのcondition（ch == '\\'など）でbody-local変数をサポート

## 主要変更

### 1. condition_lowerer.rs拡張
- `lower_condition_to_joinir`に`body_local_env`パラメータ追加
- 変数解決優先度：ConditionEnv → LoopBodyLocalEnv
- すべての再帰ヘルパー（comparison, logical_and, logical_or, not, value_expression）対応

### 2. conditional_step_emitter.rs修正
- `emit_conditional_step_update`に`body_local_env`パラメータ追加
- condition loweringにbody-local環境を渡す

### 3. loop_with_break_minimal.rs修正
- break condition loweringをbody-local init の**後**に移動（line 411）
- header_break_lowering::lower_break_conditionにbody_local_env渡す
- emit_conditional_step_updateにbody_local_env渡す（line 620）

### 4. header_break_lowering.rs修正
- `lower_break_condition`に`body_local_env`パラメータ追加
- scope_managerにbody-local環境を渡す

### 5. 全呼び出し箇所修正
- expr_lowerer.rs (2箇所)
- method_call_lowerer.rs (2箇所)
- loop_with_if_phi_if_sum.rs (3箇所)
- loop_with_continue_minimal.rs (1箇所)
- carrier_update_emitter.rs (1箇所・legacy)

## アーキテクチャ改善

### Break Condition Lowering順序修正
旧: Header → **Break Cond** → Body-local Init
新: Header → **Body-local Init** → Break Cond

理由：break conditionが`ch == '\"'`のようにbody-local変数を参照する場合、body-local initが先に必要

### 変数解決優先度（Phase 92 P2-2）
1. ConditionEnv（ループパラメータ、captured変数）
2. LoopBodyLocalEnv（body-local変数like `ch`）

## テスト

### ビルド
✅ cargo build --release成功（30 warnings、0 errors）

### E2E
⚠️ body-local promotion問題でブロック（Phase 92範囲外）
- Pattern2はbody-local変数をcarrier promotionする必要あり
- 既存パターン（A-3 Trim, A-4 DigitPos）に`ch = get_char(i)`が該当しない
- **Phase 92 P2-2目標（condition loweringでbody-local変数サポート）は達成**

## 次タスク（Phase 92 P3以降）
- body-local variable promotion拡張（Pattern2で`ch`のような変数を扱う）
- P5b E2Eテスト完全動作確認

## Phase 92 P2-2完了
✅ Body-local変数のcondition lowering対応完了
✅ ConditionalStepでbody-local変数参照可能
✅ Break condition lowering順序修正

51017a0f9a feat(joinir): Phase 92 P0-2 - Skeleton to LoopPatternContext (Option A) 
SSOT principle: Pass canonicalizer-derived ConditionalStep info to Pattern2 lowerer
without re-detecting from AST.

Changes:
- router.rs: Add skeleton: Option<&'a LoopSkeleton> to LoopPatternContext
- parity_checker.rs: Return (Result, Option<LoopSkeleton>) to reuse skeleton
- routing.rs: Pass skeleton to context when joinir_dev_enabled()
- pattern2_with_break.rs: Detect ConditionalStep in can_lower()

Next: P0-3 implements actual JoinIR generation for ConditionalStep.

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

- ExitMeta expansion NOT needed initially - return ends function, no carrier reconnect needed
- Return payload self-contained within Pattern5 (temporary/direct return, no phi merge)
- ContinueReturn asset reuse: extract consistency checks only (not exit_line machinery)
- Implementation checklist prepared for next session

42339ca77f feat(mir): Phase 143 P1 - Add parse_string pattern to canonicalizer 
Expand loop canonicalizer to recognize parse_string patterns with both
continue (escape handling) and return (quote found) statements.

## Implementation

### New Pattern Detection (ast_feature_extractor.rs)
- Add `detect_parse_string_pattern()` function
- Support nested continue detection using `has_continue_node()` helper
- Recognize both return and continue in same loop body
- Return ParseStringInfo { carrier_name, delta, body_stmts }
- ~120 lines added

### Canonicalizer Integration (canonicalizer.rs)
- Try parse_string pattern first (most specific)
- Build LoopSkeleton with HeaderCond, Body, Update steps
- Set ExitContract: has_continue=true, has_return=true
- Route to Pattern4Continue (both exits present)
- ~45 lines modified

### Export Chain
- Add re-exports through 7 module levels:
  ast_feature_extractor → patterns → joinir → control_flow → builder → mir
- 10 lines total across 7 files

### Unit Test
- Add `test_parse_string_pattern_recognized()` in canonicalizer.rs
- Verify skeleton structure (3+ steps)
- Verify carrier (name="p", delta=1, role=Counter)
- Verify exit contract (continue=true, return=true, break=false)
- Verify routing decision (Pattern4Continue, no missing_caps)
- ~180 lines added

## Target Pattern
`tools/selfhost/test_pattern4_parse_string.hako`

Pattern structure:
- Check for closing quote → return
- Check for escape sequence → continue (nested inside another if)
- Regular character processing → p++

## Results
- ✅ Strict parity green: Pattern4Continue
- ✅ All 19 unit tests pass
- ✅ Nested continue detection working
- ✅ ExitContract correctly set (first pattern with both continue+return)
- ✅ Default behavior unchanged

## Technical Challenges
1. Nested continue detection required recursive search
2. First pattern with both has_continue=true AND has_return=true
3. Variable step updates (p++ vs p+=2) handled with base delta

## Statistics
- New patterns: 1 (parse_string)
- Total patterns: 4 (skip_whitespace, parse_number, continue, parse_string)
- New capabilities: 0 (uses existing ConstStep)
- Lines added: ~300
- Files modified: 9
- Parity status: Green ✅

d605611a16 feat(canonicalizer): Phase 143-P0 - parse_number pattern support 
Add parse_number pattern recognition to canonicalizer, expanding adaptation
range for digit collection loops with break in THEN clause.

## Changes

### New Recognizer (ast_feature_extractor.rs)
- `detect_parse_number_pattern()`: Detects `if invalid { break }` pattern
- `ParseNumberInfo`: Struct for extracted pattern info
- ~150 lines added

### Canonicalizer Integration (canonicalizer.rs)
- Parse_number pattern detection before skip_whitespace
- LoopSkeleton construction with 4 steps (Header + Body x2 + Update)
- Routes to Pattern2Break (has_break=true)
- ~60 lines modified

### Export Chain (6 files)
- patterns/mod.rs → joinir/mod.rs → control_flow/mod.rs
- builder.rs → mir/mod.rs
- 8 lines total

### Tests
- `test_parse_number_pattern_recognized()`: Unit test for recognition
- Strict parity verification: GREEN (canonical and router agree)
- ~130 lines added

## Pattern Comparison

| Aspect | Skip Whitespace | Parse Number |
|--------|----------------|--------------|
| Break location | ELSE clause | THEN clause |
| Pattern | `if cond { update } else { break }` | `if invalid { break } rest... update` |
| Body after if | None | Required (result append) |

## Results

- ✅ Skeleton creation successful
- ✅ RoutingDecision matches router (Pattern2Break)
- ✅ Strict parity OK (canonicalizer ↔ router agreement)
- ✅ Unit test PASS
- ✅ Manual test: test_pattern2_parse_number.hako executes correctly

## Statistics

- New patterns: 1 (parse_number)
- Total patterns: 3 (skip_whitespace, parse_number, continue)
- Lines added: ~280
- Files modified: 8
- Parity status: Green ✅

58f66e3fa2 feat(mir): Phase 137-5 - Decision Policy SSOT化完了 
## 目的
Canonicalizer の RoutingDecision.chosen を「lowerer 選択の最終結果」にする
（構造クラス名ではなく ExitContract ベースの決定）

## 実装内容

### 1. Canonicalizer の決定ロジック修正
- `src/mir/loop_canonicalizer/mod.rs`
  - `skip_whitespace` パターン認識で ExitContract (has_break=true) を考慮
  - Pattern3IfPhi → Pattern2Break に修正（構造は似ているが break あり）
  - 単体テスト更新（Pattern2Break 期待に変更）

### 2. Parity 検証テスト修正
- `src/mir/builder/control_flow/joinir/routing.rs`
  - `test_parity_check_mismatch_detected` → `test_parity_check_skip_whitespace_match`
  - Canonicalizer と Router の一致を検証（ミスマッチ検出からマッチ検証へ）
  - Phase 137-5 の SSOT 原則を反映

### 3. ドキュメント更新
- `docs/development/current/main/design/loop-canonicalizer.md`
  - Phase 137-5: Decision Policy SSOT セクション追加
  - ExitContract 優先の原則を明記
  - skip_whitespace の例を追加

- `docs/development/current/main/phases/phase-137/README.md`
  - Phase 4 完了マーク追加
  - Phase 5 完了セクション追加（実装・検証・効果）

## 検証結果
- ✅ 単体テスト: `cargo test --release --lib loop_canonicalizer::tests` (11/11 passed)
- ✅ Parity テスト: `cargo test --release --lib 'routing::tests::test_parity'` (2/2 passed)
- ✅ Strict モード: `HAKO_JOINIR_STRICT=1` で skip_whitespace parity OK

## 効果
- Router と Canonicalizer の pattern 選択が一致
- ExitContract が pattern 決定の SSOT として明確化
- 構造的特徴（if-else 等）は notes に記録（将来拡張に備える）
