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

bbfc3c1d94 refactor(joinir): Phase 287 P2 - Strengthen BackEdge/latch conditions (WIP) 
**Problem**: Phase 188.3 Pattern6 (nested loop) encounters infinite loop
- inner_step → inner_step (self-recursion) incorrectly classified as BackEdge
- → redirects to outer header (loop_step) instead of inner_step entry
- is_recursive_call causes inner recursion to overwrite outer latch values
- → PHI receives wrong values → i doesn't increment → infinite loop

**Fix 1: BackEdge classification strictness** (tail_call_classifier.rs)
- Add `is_target_loop_entry` parameter to classify_tail_call()
- BackEdge ONLY when target==loop_step (entry_func), not inner_step
- Prevents inner_step → inner_step from redirecting to outer header

**Fix 2: latch_incoming guard** (instruction_rewriter.rs)
- Change condition from `is_recursive_call || is_target_loop_entry`
  to `is_target_loop_entry` only
- Prevents inner_step self-recursion from overwriting outer loop's latch
- set_latch_incoming() now called with correct values (verified by debug)

**Status**: 🚧 WIP - Infinite loop still occurs
- set_latch_incoming('i', BasicBlockId(8), ValueId(21)) ✅ Called correctly
- But final PHI: `phi [%4, bb8]` instead of `phi [%21, bb8]` ❌
- Root cause likely in PHI generation (merge/mod.rs), not latch_incoming
- Next: Investigate why latch_incoming values aren't used in PHI

**Files**:
- src/mir/builder/control_flow/joinir/merge/tail_call_classifier.rs
- src/mir/builder/control_flow/joinir/merge/instruction_rewriter.rs

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)

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)

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）
