de1cd1fea0 refactor(joinir): Phase 287 P1 - Modularize ast_feature_extractor (facade pattern) 
Extracted pattern recognizers from ast_feature_extractor.rs (1,148 lines) into
specialized modules under pattern_recognizers/ directory.

**Structure**:
- ast_feature_extractor.rs: Facade (135 lines, re-exports)
- pattern_recognizers/: 8 modules (1,126 lines total)
  - continue_break.rs: continue/break/return detection
  - infinite_loop.rs: loop(true) detection
  - if_else_phi.rs: if-else PHI pattern detection
  - carrier_count.rs: carrier variable counting
  - parse_number.rs: parse_number pattern (+ read_digits)
  - parse_string.rs: parse_string pattern (+ continue pattern)
  - skip_whitespace.rs: skip_whitespace pattern

**Contract**:
- Semantic invariance: All existing APIs preserved via re-exports
- No routing changes, no detection spec changes
- Public API unchanged (facade pattern)

**Verification**:
- Build: 0 errors, 0 warnings
- Pattern6: RC:9 (maintained)
- Smoke tests: 154/154 PASS

a04b48416e fix(joinir): Phase 287 P2 - Pattern6 nested loop latch overwrite fix 
Fix infinite loop in Pattern6 (nested loop minimal) caused by main→loop_step
overwriting k_inner_exit→loop_step latch values.

Root cause: JoinIR main entry block was incorrectly treated as BackEdge,
causing it to overwrite the correct latch incoming values set by the true
back edge (k_inner_exit → loop_step).

Solution:
- Restrict latch recording to TailCallKind::BackEdge only
- Treat only MAIN's entry block as entry-like (not loop_step's entry block)
- Add debug_assert! to detect double latch set in future

Refactoring:
- Extract latch recording to latch_incoming_recorder module (SSOT)
- Add boundary.loop_header_func_name for explicit header identification
- Strengthen tail_call_classifier with is_source_entry_like parameter

Tests: apps/tests/phase1883_nested_minimal.hako → RC:9 (was infinite loop)
Smoke: 154/154 PASS, no regressions

a2c5fd90fe feat(joinir): Phase 188.3 - Pattern6 (NestedLoopMinimal) 選択ロジック実装 
## Phase 188.3 進捗: Phase 2 完了 (6/13 tasks)

### 実装完了 ✅

**Phase 1: Fixture作成**
- apps/tests/phase1883_nested_minimal.hako 追加
  - Add/Compare のみ（乗算なし）
  - 期待 exit code: 9 (3×3 nested loops)
- 既存 lowering で fallback 動作確認

**Phase 2: 選択ロジック (SSOT)**
- LoopPatternContext に step_tree_max_loop_depth フィールド追加
- choose_pattern_kind() に Pattern6 選択ロジック実装:
  1. Cheap check (has_inner_loop)
  2. StepTree 構築 (max_loop_depth 取得)
  3. AST validation (is_pattern6_lowerable)
- pattern6_nested_minimal.rs モジュール作成 (stub)
- LOOP_PATTERNS に Pattern6 entry 追加
- **検証**: Pattern6 が正しく選択される ✅

### 設計原則 (確認済み)

1. **Fail-Fast**: Pattern6 選択後は Ok(None) で逃げない
2. **outer 変数 write-back 検出 → validation false** (Phase 188.4+)
3. **最小実装**: inner local だけ、Pattern1 モデル二重化
4. **cfg! 依存なし**: production で動作

### 検証結果

```
[choose_pattern_kind] has_inner_loop=true
[choose_pattern_kind] max_loop_depth=2
[choose_pattern_kind] is_pattern6_lowerable=true
✅ Pattern6 SELECTED!
```

Stub からの期待エラー:
```
[ERROR] ❌ [Pattern6] Nested loop lowering not yet implemented
```

### 次: Phase 3 (Lowering 実装 - 推定4時間)

残りタスク:
- Phase 3-1: AST 抽出ヘルパー
- Phase 3-2: Validation ヘルパー
- Phase 3-3: Continuation 生成 (outer_step, inner_step, k_inner_exit)
- Phase 3-4: fixture が exit=9 を返すことを検証

### 変更ファイル

**新規**:
- apps/tests/phase1883_nested_minimal.hako
- src/mir/builder/control_flow/joinir/patterns/pattern6_nested_minimal.rs
- docs/development/current/main/phases/phase-188.{1,2,3}/README.md

**変更**:
- src/mir/builder/control_flow/joinir/routing.rs (Pattern6 選択)
- src/mir/builder/control_flow/joinir/patterns/router.rs (Context 拡張)
- src/mir/builder/control_flow/joinir/patterns/mod.rs (module 宣言)

832d018046 feat(joinir): Phase 286 P2.4.1 - Pattern8 normalizer 実装 + Fail-Fast 化 
## 概要
Pattern8 (BoolPredicateScan) を Plan line で完走させる。
stub normalizer を完全実装に置き換え、legacy fallback を禁止。

## Step 0: Fixture 簡約
- `?:` ternary → `if/else` に変更（PoC 安定化）

## Step 1: Router Fail-Fast 化
- 文字列判定 `e.contains("[normalizer/pattern8]")` を削除
- extract が Some → normalize/lower 失敗は即 Err（fallback 禁止）
- extract が None → 次の extractor へ（legacy 含む）

## Step 2: Pattern8 normalizer 実装
- CFG: preheader → header(PHI) → body → found/step → after
- found: return false（早期脱出）
- after: return true（ループ完走）
- compose::cleanup() で 2 つの Return exit をマージ

## 検証結果
- Integration: exit 7 ✅
- Plan 完走: route=plan strategy=extract pattern=Pattern8 MATCHED
- Regression: quick 154 PASS, 0 FAILED

843d094598 refactor(joinir): Phase 286 P1-P3 - Boundary contract context enrichment 
- P1: Add alloc_join_param()/alloc_join_local() API to JoinValueSpace
  - Prevents future API misuse (thin wrappers with explicit "JoinIR" context)
  - Updated docs with footnote-style number references

- P2: Enrich error context with host_fn for better diagnostics
  - Added context: &str parameter to verify_boundary_contract_at_creation()
  - Error format now shows: [merge_joinir_mir_blocks host=<fn> ...]

- P3: Add join-side info to error context (continuation count + boundary summary)
  - Uses boundary.continuation_func_ids.len() for join=
  - Adds [conts=X exits=Y conds=Z] suffix with fixed key names
  - Enables faster debugging with log-searchable format

Error format: [merge_joinir_mir_blocks host=X join=Y [conts=A exits=B conds=C]]
