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)

095213c580 refactor(smoke): Clarify auto_detect.conf responsibilities with profile parameter 
**Problem**:
- detect_optimal_config() took no arguments (line 11)
- Quick profile SSOT forcing scattered outside function (line 134-137)
- Profile-specific logic split between detect_optimal_config() and auto_configure()
- Hard to understand flow: "why is this logic duplicated?"

**Solution** (Task 4 - Low Priority):
- Accept profile parameter: `detect_optimal_config(profile)`
- Move quick profile SSOT forcing inside function (top priority)
- Eliminate duplicate logic in auto_configure()
- Update show_auto_config() to pass profile parameter

**Changes**:
- detect_optimal_config(): Add `local profile="${1:-quick}"`
- Quick SSOT check: Move to function top (early return)
- auto_configure(): Pass `"$profile"` to detect_optimal_config
- show_auto_config(): Pass `"${SMOKES_CURRENT_PROFILE:-quick}"`
- Remove 6 lines of duplicate quick forcing logic

**Benefits**:
- Single responsibility: Profile logic inside detect_optimal_config
- Clearer flow: All detection in one function
- Maintainability: One place to modify profile behavior
- Readability: Intent is explicit (profile parameter)

**Verification**:
- ✅ detect_optimal_config "quick": returns rust_vm_dynamic (SSOT)
- ✅ detect_optimal_config "integration": returns llvm_static
- ✅ Quick profile: 154/154 PASS

**Note**: This is a low-impact refactoring (code organization only)
- Behavior unchanged (same logic, better location)
- No performance impact
- Future-proof for profile-specific detection

1869396fd7 refactor(smoke): Consolidate LLVM detection to can_run_llvm() SSOT 
**Problem**:
- LLVM availability check scattered across 9+ test files
- Duplicate grep patterns: `--version | grep -q "features.*llvm"`
- Hard to maintain when detection logic changes
- Potential SKIP hell when conditions diverge

**Solution** (Task 3 - Medium Priority):
- Create `can_run_llvm()` function in test_runner.sh (SSOT)
- Consolidate both detection methods:
  1. Primary: `--version | grep features.*llvm`
  2. Fallback: `strings | grep ny-llvmc|NYASH_LLVM_USE_HARNESS`
- Replace all inline checks with function call

**Files Changed**:
- test_runner.sh: Add can_run_llvm() + update run_nyash_llvm()
- 9 test files: Replace inline grep with can_run_llvm()
  - quick: phase285_weak_basic_llvm.sh
  - integration: phase284/285, json_{lint,pp,query}, parity tests

**Benefits**:
- Single point of maintenance (SSOT)
- Consistent LLVM detection across all tests
- Easy to extend (e.g., add Python llvmlite check)
- Prevents future SKIP divergence

**Verification**:
- ✅ phase284_p2_return_in_loop_llvm: PASS
- ✅ phase285_weak_basic_llvm: PASS
- ✅ Quick profile: 154/154 PASS

798c193cbe refactor(kernel): Extract weak reference FFI to ffi/weak.rs module 
**Problem**:
- nyash_kernel/src/lib.rs is 1295 lines (monolithic FFI functions)
- Hard to navigate and maintain
- No clear module boundaries

**Solution** (Task 2 - Medium Priority):
- Create `ffi/` module structure
- Extract weak reference functions to `ffi/weak.rs` (74 lines)
  - nyrt_weak_new
  - nyrt_weak_to_strong
  - nyrt_weak_drop
- lib.rs: 1295 → 1221 lines (-74 lines, -5.7%)
- Re-export via `pub use ffi::weak::*` for ABI compatibility

**Architecture**:
- Box-First: Clear module boundaries (SSOT for weak refs)
- Reversible: Can merge back if needed (small, safe step)
- ABI stable: #[no_mangle] exports preserved

**Verification**:
- ✅ Build successful (cargo build -p nyash_kernel)
- ✅ phase285_p2_weak_upgrade_success_llvm: PASS
- ✅ phase285_p2_weak_upgrade_fail_llvm: PASS
- ✅ Quick profile: 154/154 PASS

**Next steps** (deferred to future):
- Extract string FFI (~11 functions)
- Extract memory management FFI
- Extract box operations FFI

d7c6df3675 refactor(smoke): Phase 284 P2 - LLVM harness exit code SSOT 
**Problem**:
- phase284_p2_return_in_loop_llvm.sh used fallback: exit code OR output grep
- Inconsistent with exit code SSOT policy for LLVM harness tests
- Output pollution from harness logs makes grep unreliable

**Solution** (Task 1 - High Priority):
- Remove `|| echo "$OUTPUT" | grep -qE "(^7$|RC: 7$)"` fallback
- Pure exit code validation: `if [ "$EXIT_CODE" -eq 7 ]`
- OUTPUT kept for error debugging only (line 40)
- Align with phase285_p2 tests (already using exit code SSOT)

**Verification**:
- ✅ phase284_p2_return_in_loop_llvm: PASS (exit 7)
- ✅ phase285_p2_weak_upgrade_success_llvm: PASS (exit 2)
- ✅ phase285_p2_weak_upgrade_fail_llvm: PASS (exit 1)
- ✅ Quick profile: 154/154 PASS

**Impact**:
- 1 file changed, 5 lines modified
- More reliable LLVM test validation
- No regression in existing tests

5a88c4eb23 refactor(llvm-py): Phase 3 boxification - Strategic extraction 
Extract complex logic while keeping simple parts inline:

1. StringBoxerBox (15 lines)
   - Box string pointers (i8*) to handles (i64)
   - Eliminate function declaration boilerplate
   - Clear single responsibility

2. ReturnPhiSynthesizerBox (101 lines)
   - Synthesize PHI nodes for return values
   - should_synthesize_phi(): Zero-like detection
   - synthesize_phi(): PHI creation with predecessors
   - Respects _disable_phi_synthesis flag

What was NOT boxified (good decisions):
- Fast path vmap lookup (13 lines): Too simple
- Global vmap fallback (7 lines): Too small
- Default value generation (18 lines): Clear as-is

Impact:
- lower_return(): 166→117 lines (-29% reduction)
- File size: 250→352 lines (+102 for organization)
- Testable units: 2→4 (+2 new Boxes)

Tests:
- phase286_pattern5_return_min.hako: PASS (exit 7)
- phase284_p1_return_in_loop_llvm.sh: PASS
- phase284_p2_return_in_loop_llvm.sh: PASS

32aa0ddf69 refactor(llvm-py): Box-First refactoring of ret.py (Phase 1-2) 
Extract two responsibility Boxes following Box-First principle:

1. UnreachableReturnHandlerBox (Phase 1)
   - Handle unreachable block returns with Fail-Fast principle
   - Implements Phase 284-P2 unreachable semantics
   - Moved os/sys imports to file header

2. ReturnTypeAdjusterBox (Phase 2)
   - Handle ptr↔int conversion and int width adjustment
   - Isolate type coercion logic for LLVM compatibility
   - Support truncate/extend for integer width mismatches

Changes:
- File size: 205→249 lines (+21% for better organization)
- Reduced lower_return() complexity
- Preserved all Phase 284-P2 comments and semantics
- No breaking changes

Tests:
- phase286_pattern5_return_min.hako: PASS (exit 7)
- phase284_p2_return_in_loop_llvm.sh: PASS
- Quick profile: 154/154 PASS

225600b5f9 fix(llvm): Phase 284 P2 - Use unreachable for null returns (Fail-Fast) 
MIR generates unreachable blocks with null return values (e.g., after loop(true)).
LLVM type-checks ALL blocks, so we must match function signatures.

Solution: Use builder.unreachable() instead of ret void for non-void functions.
- Type-safe: Satisfies LLVM type checker without return value
- Fail-Fast: Immediate crash if "unreachable" block is executed
- No silent failures

Test results:
✅ phase284_p2_return_in_loop_llvm: PASS (integration)
✅ phase285_p2_weak_upgrade_success_llvm: PASS (already passing)
✅ quick 154/154: PASS (no regression)

ce2baa0d47 feat(llvm): Phase 285 P3 - KeepAlive/ReleaseStrong LLVM implementation 
Phase 285 P3: LLVM One-Pass (VM/LLVM一気通貫の最小ゲート)

## 実装内容

### 1. LLVM Backend (Python)
- src/llvm_py/instructions/lifecycle.py: NEW
  - lower_keepalive(): no-op (DCE/liveness only)
  - lower_release_strong(): ny_release_strong() 呼び出し
- src/llvm_py/builders/instruction_lower.py:
  - KeepAlive/ReleaseStrong ディスパッチエントリ追加

### 2. Runtime (Rust)
- crates/nyash_kernel/src/lib.rs:
  - ny_release_strong(handle: i64): handles::drop() 呼び出し
  - Phase 287対応（変数上書きセマンティクス）

### 3. MIR JSON Serialization
- src/runner/mir_json_emit.rs:
  - KeepAlive/ReleaseStrong JSON emit 追加（両関数）
  - {"op":"keepalive","values":[...]}
  - {"op":"release_strong","values":[...]}

## テスト結果

✅ **phase285_p2_weak_upgrade_fail_llvm**: PASS (exit 1, weak_to_strong null)
⏸️ **phase285_p2_weak_upgrade_success_llvm**: SKIP (--version に features 表示なし)
⏸️ **phase284_p2_return_in_loop_llvm**: SKIP (同上)

## SKIP理由（--version feature表示問題）

テストスクリプトが `--version | grep "features.*llvm"` で環境チェックするが、
現在の --version は "nyash 1.0" のみ出力。LLVM feature有効でも SKIP される。

**対応方針**: Phase 285 P3 目的（KeepAlive/ReleaseStrong LLVM実装）達成。
--version feature表示は Phase 286以降で対応予定。

## 検証

- cargo build --release --features llvm: OK
- weak_upgrade_fail_llvm: PASS (VM/LLVM parity確認)
- quick gate: 154/154 PASS (退行なし)

3bb865c6b0 refactor(mir): Separate KeepAlive/ReleaseStrong instructions (Phase 287) 
Phase 287: KeepAlive/ReleaseStrong 命令分離

## 変更内容（2つの側面）

### 1. 命令セマンティクスの分離
- KeepAlive { values, drop_after: bool } を2命令に分離
  - KeepAlive { values }: スコープ終了での生存維持（PURE）
  - ReleaseStrong { values }: 変数上書き時の強参照解放（WRITE）
- 効果分析の明確化: PURE vs WRITE の境界確定

### 2. VM実行サポート
- handlers/mod.rs: KeepAlive → 完全 no-op
- handlers/mod.rs: ReleaseStrong → release_strong_refs() 呼び出し
- handlers/lifecycle.rs: handle_keepalive() 削除

## 影響範囲
- 10 ファイル修正（31箇所の出現を全変換）
- instruction.rs, builder.rs, lexical_scope.rs, methods.rs,
  display.rs, printer_helpers.rs, query.rs, joinir_id_remapper.rs,
  handlers/mod.rs, handlers/lifecycle.rs

## 検証
- 154/154 quick smoke PASS
- weak テスト回帰なし（weak_upgrade_fail, weak_basic）
- rg -n drop_after src → 0 件（完全除去確認）
- MIRダンプで release_strong/keepalive 正常表示

3bf0dee2b0 feat(mir): Phase 285 P2.1 - KeepAlive instruction for weak ref semantics 
Add KeepAlive instruction to fix hidden root problem where x = null
doesn't properly drop the strong reference.

Key changes:
- Add KeepAlive { values, drop_after } instruction to MIR
- Emit KeepAlive[drop=true] in build_assignment() before variable overwrite
- Emit KeepAlive[drop=false] in pop_lexical_scope() at scope end
- VM handler: when drop_after=true, remove ALL ValueIds pointing to
  the same Arc (handles SSA Copy chains)

Test results:
- weak_upgrade_fail: exit 1 ✅ (weak_to_strong returns null after x=null)
- weak_basic: exit 2 ✅ (weak_to_strong succeeds while x alive)
- quick smoke: 154/154 PASS ✅

58ceb3de2f feat(smoke): Phase 285 P2 - weak conformance smokes (success pattern) 
Phase 285 P2: weak の意味論（weak <expr> + weak_to_strong() 成功/失敗）を integration smoke で固定

実装内容:
- Fixture A（成功パターン）: exit 0 → exit 2 に変更（fail=1, success=2 で明確化）
- Fixture B（失敗パターン）: 明示 drop (x = null) 方式で作成
- VM smoke success: PASS
- LLVM smoke success: SKIP（backend unavailable）
- VM/LLVM smoke fail: SKIP（hidden root 問題で理由付き）

既知の問題:
- x = null で明示 drop しても weak_to_strong が成功（hidden root が strong ref を保持）
- Phase 285 P2.1 (investigation) で root 保持箇所を棚卸し予定

スコープ:
- Block scope drop conformance は別タスク（未整合の可能性あり）
- P2 では明示 drop 方式で weak の最小意味論（non-owning）のみを検証

検証:
- quick smoke 154/154 PASS 維持
- integration smoke 4本（success 2本 PASS/SKIP、fail 2本 SKIP）

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
