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 ✅

bfd324d7b9 feat(joinir): Phase 256 P1.5 - JoinInst::Select 命令サポート（根治） 
## 変更内容

Task 1（既完了）: boundary パラメータを bridge 経路全体に伝播
- conversion_pipeline.rs, bridge.rs（複数箇所）, meta.rs, routing_legacy_binding.rs, execute_box.rs

Task 2-A～2-D: Select 命令の実装
- 2-A: MirInstruction::Select バリアント追加
- 2-B: JoinIR Select → MIR Select 直接変換（branch+phi展開廃止）
- 2-C: ⭐ joinir_id_remapper に Select remap case（ValueId変換の根治）
- 2-D: value_collector に Select case

## 根本原因解決

Pattern7 の JoinInst::Select が JoinIR→MIR で未対応
→ ValueId(1002) → ValueId(57) のリマップが行われず
→ "use of undefined value ValueId(57)" エラー

## 現在地

✅ cargo check: 0 errors
⏳ Pattern7/6 VM test（Task 2-E LLVM実装後）

c6edbaaf3a feat(mir): Phase 63-6-1/2 MIR Phi type_hint field & JoinIR propagation 
Phase 63-6-1: MirInstruction::Phi に type_hint フィールド追加
- Added `type_hint: Option<MirType>` field to Phi instruction
- Updated 21 files with type_hint initialization (all set to None for legacy paths)
- Pattern matching updated across codebase (11 files)
- Test code updated (basic_block.rs)

Phase 63-6-2: JoinIR→MIR Bridge で型ヒント伝播実装
- Modified convert.rs: Select → MIR now creates PHI with type_hint
- Removed Copy instructions from then/else blocks
- PHI instruction at merge block receives type_hint from JoinIR Select
- Test verification: ✅ Type hint propagation successful (Some(Integer))

Modified files:
- instruction.rs: Added type_hint field definition
- join_ir_vm_bridge/convert.rs: Select lowering with PHI + type_hint
- 19 other files: type_hint field initialization

Test results:
- ✅ test_type_hint_propagation_simple: Type hint = Some(Integer) confirmed
- ✅ 7/8 if_select tests passing (1 race condition, passes individually)

Next: Phase 63-6-3 (lifecycle.rs で型ヒント使用)

525e59bc8d feat(loop-phi): Add body-local variable PHI generation for Rust AST loops 
Phase 25.1c/k: Fix ValueId undefined errors in loops with body-local variables

**Problem:**
- FuncScannerBox.scan_all_boxes/1 and BreakFinderBox._find_loops/2 had ValueId
  undefined errors for variables declared inside loop bodies
- LoopFormBuilder only generated PHIs for preheader variables, missing body-locals
- Example: `local ch = s.substring(i, i+1)` inside loop → undefined on next iteration

**Solution:**
1. **Rust AST path** (src/mir/loop_builder.rs):
   - Detect body-local variables by comparing body_end_vars vs current_vars
   - Generate empty PHI nodes at loop header for body-local variables
   - Seal PHIs with latch + continue snapshot inputs after seal_phis()
   - Added HAKO_LOOP_PHI_TRACE=1 logging for debugging

2. **JSON v0 path** (already fixed in previous session):
   - src/runner/json_v0_bridge/lowering/loop_.rs handles body-locals
   - Uses same strategy but for JSON v0 bridge lowering

**Results:**
- ✅ FuncScannerBox.scan_all_boxes: 41 body-local PHIs generated
- ✅ Main.main (demo harness): 23 body-local PHIs generated
- ⚠️ Still some ValueId undefined errors remaining (exit PHI issue)

**Files changed:**
- src/mir/loop_builder.rs: body-local PHI generation logic
- lang/src/compiler/entry/func_scanner.hako: debug logging
- /tmp/stageb_funcscan_demo.hako: test harness

5b7ef32277 feat(phase-5.2): Complete backend cleanup - reject deprecated MIR instructions 
Phase 5.2 of MIR 35→26 reduction project:
- VM backend: Reject all 17 deprecated instructions with proper error messages
- WASM backend: Reject deprecated instructions with migration guidance
- All deprecated instructions now properly handled in both backends
- Build successful with expected deprecation warnings

Deprecated instructions removed:
- UnaryOp → Use BinOp
- Load/Store → Use BoxFieldLoad/BoxFieldStore
- ArrayGet/ArraySet → Use BoxFieldLoad/BoxFieldStore or intrinsics
- Print/Debug → Use Call @print/@debug
- TypeCheck/Cast → Use Call @type_check/@cast
- Throw/Catch → Use Call @throw/@catch
- RefNew → References handled implicitly
- BarrierRead/BarrierWrite → Use AtomicFence
- FutureNew/FutureSet/Await → Use NewBox/BoxCall
- Copy/Nop → Not needed in final IR

3df87fb1ce fix(phase-4.3c-3): Fix StringBox literal handling in MIR builder 
Phase 4-3c-3 Complete: WASM host functions now correctly output string content

## Changes:
- Fixed MIR builder to handle StringBox with string literal arguments
- Special case for  to generate proper string constants
- Removed debug output after successful verification
- WASM now correctly outputs "Hello MIR!" instead of "StringBox"

## Test Results:
- MIR generation: ✅ Generates  correctly
- WASM compilation: ✅ String data correctly placed at offset 4096
- WASM execution: ✅ Outputs "Hello MIR\!" as expected

## Technical Details:
- Modified build_new_expression() to detect StringBox with literal arguments
- Generates Const instruction with actual string content
- Host function reads StringBox memory layout correctly

This completes the WASM string output functionality for Phase 4.
