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

f74b7d2b04 📦 Hotfix 1 & 2: Parameter ValueId Reservation + Exit PHI Validation (Box-First Theory) 
**箱理論に基づく根治的修正**：

## 🎯 Hotfix 1: Parameter ValueId Reservation (パラメータ ValueId 予約)

### 根本原因
- MirFunction counter が params.len() を考慮していなかった
- local variables が parameter ValueIds を上書き

### 箱理論的解決
1. **LoopFormContext Box**
   - パラメータ予約を明示的に管理
   - 境界をはっきりさせる

2. **MirFunction::new() 改善**
   - `initial_counter = param_count.max(1)` でパラメータ予約
   - Parameters are %0, %1, ..., %N-1

3. **ensure_counter_after() 強化**
   - パラメータ数 + 既存 ValueIds 両方を考慮
   - `min_counter = param_count.max(max_id + 1)`

4. **reserve_parameter_value_ids() 追加**
   - 明示的な予約メソッド（Box-First）

## 🎯 Hotfix 2: Exit PHI Predecessor Validation (Exit PHI 検証)

### 根本原因
- LoopForm builder が存在しないブロックを PHI predecessor に追加
- 「幽霊ブロック」問題

### 箱理論的解決
1. **LoopFormOps.block_exists() 追加**
   - CFG 存在確認メソッド
   - 境界を明確化

2. **build_exit_phis() 検証**
   - 非存在ブロックをスキップ
   - デバッグログ付き

### 実装ファイル

73844dbe04 feat(builder): CalleeBoxKind構造ガードで静的/ランタイムBox混線を根絶 
🎯 箱理論の実践: 「境界を作る」原則による構造レベル分離

## 問題
- StageBArgsBox.resolve_src内のargs.get(i)が
  Stage1UsingResolverBox.getに化ける（静的Box名混入）
- 未定義ValueIdエラー発生（receiver定義なし）

## 解決策（構造ガード）
✅ CalleeBoxKind enum追加
  - StaticCompiler: Stage-B/Stage-1コンパイラBox
  - RuntimeData: MapBox/ArrayBox等ランタイムBox
  - UserDefined: ユーザー定義Box

✅ classify_box_kind(): Box名から種別判定
  - 静的Box群を明示的に列挙（1箇所に集約）
  - ランタイムBox群を明示的に列挙
  - 将来の拡張も容易

✅ apply_static_runtime_guard(): 混線検出・正規化
  - me-call判定（receiver型==box_name → 静的降下に委ねる）
  - 真の混線検出（receiver型≠box_name → 正規化）
  - トレースログで可視化

## 効果
- 修正前: Invalid value ValueId(150/187)
- 修正後: Unknown method 'is_space' (別issue、StringBox実装不足)
- → 静的Box名混入問題を根絶！

## 箱理論原則
- ✅ 境界を作る: Static/Runtime/UserDefinedを構造的に分離
- ✅ Fail-Fast: フォールバックより明示的エラー
- ✅ 箱にする: CalleeBoxKindでBox種類を1箇所に集約

## ファイル
- src/mir/definitions/call_unified.rs: CalleeBoxKind enum
- src/mir/builder/calls/call_unified.rs: classify_box_kind()
- src/mir/builder/calls/emit.rs: apply_static_runtime_guard()
- docs/development/roadmap/phases/phase-25.1d/README.md: 箱化メモ更新

c27f6466e8 fix(builder): BoxCompilationContext clear()アプローチ確立 
🎯 箱理論: swap累積バグを修正し、clear()で完全独立化を実現

## 問題
- swap実装は ctx に変数が累積され、次のメソッドで汚染される
- StageBArgsBox.resolve_src で ValueId(21) 未定義エラー

## 解決策
- swap → clear() に変更（開始時・終了時両方）
- context_active mode: clear() のみ（完全独立）
- legacy mode: saved_var_map で従来の挙動維持

## 成果
✅ StageBArgsBox.resolve_src - 成功！
❌ StageBBodyExtractorBox.build_body_src - 次の問題箇所（進展！）

## 実装
- src/mir/builder/builder_calls.rs:
  - 開始時: context_active なら clear()（swap削除）
  - 終了時: context_active なら clear()（swap back削除）
  - legacy mode: saved_var_map で復元

c459135238 feat(mir/phi): improve LoopForm parameter detection - track param names 
**Problem**: is_parameter() was too simple, checking only ValueId which changes
through copies/PHIs. This caused parameters like 'data' to be misclassified as
carriers, leading to incorrect PHI construction.

**Solution**: Track original parameter names at function entry.

**Changes**:

1. **Added function_param_names field** (builder.rs):
   - HashSet<String> to track original parameter names
   - Populated in lower_static_method_as_function()
   - Cleared and repopulated for each new function

2. **Improved is_parameter()** (loop_builder.rs):
   - Check name against function_param_names instead of ValueId
   - More reliable than checking func.params (ValueIds change)
   - __pin$*$@* variables correctly classified as carriers
   - Added debug logging with NYASH_LOOPFORM_DEBUG

3. **Enhanced debug output** (loopform_builder.rs):
   - Show carrier/pinned classification during prepare_structure()
   - Show variable_map state after emit_header_phis()

**Test Results**:
- ✅ 'args' correctly identified as parameter (was working)
- ✅ 'data' now correctly identified as parameter (was broken)
- ✅ __pin variables correctly classified as carriers
- ✅ PHI values allocated and variable_map updated correctly
- ⚠️ ValueId undefined errors persist (separate issue)

**Remaining Issue**:
ValueId(10) undefined error suggests PHI visibility problem or VM verification
issue. Needs further investigation of emit_phi_at_block_start() or VM executor.

**Backward Compatibility**:
- Flag OFF: 100% existing behavior preserved (legacy path unchanged)
- Feature-flagged with NYASH_LOOPFORM_PHI_V2=1

f85e485195 feat(mir/phi): add LoopForm Meta-Box for PHI circular dependency solution 
**Problem**: ValueId(14)/ValueId(17) circular dependency in multi-carrier
loop PHI construction. Loop body PHIs referenced ValueIds not defined in
header exit block, causing SSA use-before-def violations.

**Root Cause**: Interleaved ValueId allocation when processing pinned
(parameters like 'me', 'args') and carrier (locals like 'i', 'n')
variables created forward references:
```
Iteration 1: pre_copy=%13, phi=%14  ✅
Iteration 2: pre_copy=%15, phi=%19  ✅ (but %14 not yet emitted!)
Body PHI: phi %17 = [%14, bb3]  ❌ %14 doesn't exist in bb3
```

**Solution**: LoopForm Meta-Box with 3-pass PHI construction algorithm
inspired by Braun et al. (2013) "Simple and Efficient SSA Construction".

**Core Design**:
- **Meta-Box abstraction**: Treat entire loop as single Box with explicit
  carrier/pinned separation
- **Three-pass algorithm**:
  1. Allocate ALL ValueIds upfront (no emission)
  2. Emit preheader copies in deterministic order
  3. Emit header PHIs (incomplete)
  4. Seal PHIs after loop body (complete)
- **Guarantees**: No circular dependencies possible (all IDs pre-allocated)

**Academic Foundation**:
- Cytron et al. (1991): Classical SSA with dominance frontiers
- Braun et al. (2013): Simple SSA with incomplete φ-nodes ✅ Applied here
- LLVM Canonical Loop Form: Preheader→Header(PHI)→Body→Latch

**Files Added**:

1. **src/mir/phi_core/loopform_builder.rs** (360 lines):
   - LoopFormBuilder struct with carrier/pinned separation
   - LoopFormOps trait (abstraction layer)
   - Three-pass algorithm implementation
   - Unit tests (all pass ✅)

2. **docs/development/analysis/loopform-phi-circular-dependency-solution.md**:
   - Comprehensive problem analysis (600+ lines)
   - Academic literature review
   - Alternative approaches comparison
   - Detailed implementation plan

3. **docs/development/analysis/LOOPFORM_PHI_SOLUTION_SUMMARY.md**:
   - Executive summary (250 lines)
   - Testing strategy
   - Migration timeline (4 weeks)
   - Risk assessment

4. **docs/development/analysis/LOOPFORM_PHI_NEXT_STEPS.md**:
   - Step-by-step integration guide (400 lines)
   - Code snippets for mir/loop_builder.rs
   - Troubleshooting guide
   - Success metrics

**Testing**:
- ✅ Unit tests pass (deterministic allocation verified)
- ⏳ Integration tests (Week 2 with feature flag)
- ⏳ Selfhost support (Week 3)

**Migration Strategy**:
- Week 1 (Current): ✅ Prototype complete
- Week 2: Integration with NYASH_LOOPFORM_PHI_V2=1 feature flag
- Week 3: Selfhost compiler support
- Week 4: Full migration, deprecate old code

**Advantages**:
1. **Correctness**: Guarantees SSA definition-before-use
2. **Simplicity**: ~360 lines (preserves Box Theory philosophy)
3. **Academic alignment**: Matches state-of-art SSA construction
4. **Backward compatible**: Feature-flagged with rollback capability

**Impact**: This resolves the fundamental ValueId circular dependency
issue blocking Stage-B selfhosting, while maintaining the LoopForm
design philosophy of "normalize everything, confine to scope".

**Total Contribution**: ~2,000 lines of code + documentation

**Next Steps**: Integrate LoopFormBuilder into src/mir/loop_builder.rs
following LOOPFORM_PHI_NEXT_STEPS.md guide (estimated 2-4 hours).

nyash-codex
eadde8d1dd fix(mir/builder): use function-local ValueId throughout MIR builder 
Phase 25.1b: Complete SSA fix - eliminate all global ValueId usage in function contexts.

Root cause: ~75 locations throughout MIR builder were using global value
generator (self.value_gen.next()) instead of function-local allocator
(f.next_value_id()), causing SSA verification failures and runtime
"use of undefined value" errors.

Solution:
- Added next_value_id() helper that automatically chooses correct allocator
- Fixed 19 files with ~75 occurrences of ValueId allocation
- All function-context allocations now use function-local IDs

Files modified:
- src/mir/builder/utils.rs: Added next_value_id() helper, fixed 8 locations
- src/mir/builder/builder_calls.rs: 17 fixes
- src/mir/builder/ops.rs: 8 fixes
- src/mir/builder/stmts.rs: 7 fixes
- src/mir/builder/emission/constant.rs: 6 fixes
- src/mir/builder/rewrite/*.rs: 10 fixes
- + 13 other files

Verification:
- cargo build --release: SUCCESS
- Simple tests with NYASH_VM_VERIFY_MIR=1: Zero undefined errors
- Multi-parameter static methods: All working

Known remaining: ValueId(22) in Stage-B (separate issue to investigate)

13f21334c9 fix(aot): resolve copy chains in PHI propagation for deep loop coverage 
Fix CollectionsHot type_table to resolve copy chains when propagating types
through PHI nodes, enabling ArrayBox optimization in deeply nested loops (matmul).

**Root Cause:**
- PHI incoming values were checked directly in type_table
- Copy chains (e.g., SSA 56→11) were not resolved
- Types failed to propagate through deep loop nesting

**Solution:**
- Add copy_src_map parameter to build_type_table()
- Resolve copy chains before checking if PHI incoming values are typed
- Multi-pass fixpoint algorithm (up to 12 passes) ensures convergence

**Impact:**
- matmul: ArrayBox A/B/C now propagate through nested loops
- Expected: boxcall→externcall conversion for get/set/push
- Backwards compatible: opt-in (NYASH_AOT_COLLECTIONS_HOT=1), no behavior change when disabled

**Analysis:**
- Documented in docs/development/analysis/matmul_collections_hot_fix.md
- Box→SSA flow traced: A(dst=2)→...→71(get), B(dst=3)→...→73(get), C(dst=4)→...→105(set)

**Testing:** Pending verification due to VM step budget constraints

8b44c5009f fix(mir): fix else block scope bug - PHI materialization order 
Root Cause:
- Else blocks were not propagating variable assignments to outer scope
- Bug 1 (if_form.rs): PHI materialization happened before variable_map reset,
  causing PHI nodes to be lost
- Bug 2 (phi.rs): Variable merge didn't check if else branch modified variables

Changes:
- src/mir/builder/if_form.rs:93-127
  - Reordered: reset variable_map BEFORE materializing PHI nodes
  - Now matches then-branch pattern (reset → materialize → execute)
  - Applied to both "else" and "no else" branches for consistency
- src/mir/builder/phi.rs:137-154
  - Added else_modified_var check to detect variable modifications
  - Use modified value from else_var_map_end_opt when available
  - Fall back to pre-if value only when truly not modified

Test Results:
✅ Simple block: { x=42 } → 42
✅ If block: if 1 { x=42 } → 42
✅ Else block: if 0 { x=99 } else { x=42 } → 42 (FIXED!)
✅ Stage-B body extraction: "return 42" correctly extracted (was null)

Impact:
- Else block variable assignments now work correctly
- Stage-B compiler body extraction restored
- Selfhost builder path can now function
- Foundation for Phase 21.x progress

52b62c5772 feat(phase21.5): Stage-B parser loop fix + delegate path stabilization 
## 修正内容

### 1. Stage-B パーサー修正（偶然の回避）
- **ファイル**:
  - `lang/src/compiler/parser/expr/parser_expr_box.hako`
  - `lang/src/compiler/parser/stmt/parser_control_box.hako`
- **問題**: ネストループで gpos が正しく進まず、loop の cond/body が壊れる
- **回避策**: new 式のメソッドチェーン処理追加で別ループを導入
- **結果**: MIR 生成が変わって VM gpos バグを回避

### 2. delegate パス動作確認
- **テスト**: `/tmp/loop_min.hako` → rc=10 ✅
- **MIR構造**: 正しい PHI/compare/binop を生成
- **チェーン**: hakorune parser → Rust delegate → LLVM EXE 完動

### 3. ドキュメント追加
- `docs/development/analysis/` - delegate 分析
- `docs/development/guides/` - ループテストガイド
- `docs/development/testing/` - Stage-B 検証報告

### 4. カナリーテスト追加
- `tools/smokes/v2/profiles/quick/core/phase2100/` 配下に複数追加
- emit_boxcall_length_canary_vm.sh
- stageb_parser_loop_json_canary_vm.sh
- 他

### 受け入れ基準
- ✅ delegate パス: rc=10 返す
- ✅ FORCE パス: rc=10 返す（既存）
- ✅ MIR 構造: 正しい PHI incoming と compare
- ✅ 既定挙動: 不変（dev トグルのみ）

b9e9c967fb feat(phase21.5): Fix --emit-mir-json BoxCall emission + EXE staging docs 
## Task 2: BoxCall Emission Fix ✅
- Fix: --emit-mir-json now properly emits boxcall for method calls when NYASH_MIR_UNIFIED_CALL=0
- Root cause: v0 format fallback wasn't inspecting Callee::Method enum
- Implementation: Added proper v0 boxcall emission with dst_type hints
- Location: src/runner/mir_json_emit.rs:329-368
- Preserves: All default behavior, only affects explicit NYASH_MIR_UNIFIED_CALL=0

## Task 4: Documentation Updates ✅
- Added: selfhost_exe_stageb_quick_guide.md (comprehensive usage guide)
- Added: selfhost_exe_stageb_verification_report.md (test results)
- Updated: tools/selfhost_exe_stageb.sh with prerequisite comments
- Documented: EXE test timeout recommendations (--timeout 120)
- Documented: NYASH_EXE_ARGV=1 usage with ensure_ny_main/argv_get
- Added: Phase 2034 emit_boxcall_length canary test

## Implementation Principles
- 既定挙動不変 (Default behavior unchanged)
- 最小差分 (Minimal diff)
- ロールバック容易 (Easy rollback via clear else-if block)
- Dev toggle guarded (NYASH_MIR_UNIFIED_CALL=0 explicit activation)

6055d53eff feat(phase21.5/22.1): MirBuilder JsonFrag refactor + FileBox ring-1 + registry tests 
Phase 21.5 (AOT/LLVM Optimization Prep)
- FileBox ring-1 (core-ro) provider: priority=-100, always available, no panic path
  - src/runner/modes/common_util/provider_registry.rs: CoreRoFileProviderFactory
  - Auto-registers at startup, eliminates fallback panic structurally
- StringBox fast path prototypes (length/size optimization)
- Performance benchmarks (C/Python/Hako comparison baseline)

Phase 22.1 (JsonFrag Unification)
- JsonFrag.last_index_of_from() for backward search (VM fallback)
- Replace hand-written lastIndexOf in lower_loop_sum_bc_box.hako
- SentinelExtractorBox for Break/Continue pattern extraction

MirBuilder Refactor (Box → JsonFrag Migration)
- 20+ lower_*_box.hako: Box-heavy → JsonFrag text assembly
- MirBuilderMinBox: lightweight using set for dev env
- Registry-only fast path with [registry:*] tag observation
- pattern_util_box.hako: enhanced pattern matching

Dev Environment & Testing
- Dev toggles: SMOKES_DEV_PREINCLUDE=1 (point-enable), HAKO_MIR_BUILDER_SKIP_LOOPS=1
- phase2160: registry opt-in tests (array/map get/set/push/len) - content verification
- phase2034: rc-dependent → token grep (grep -F based validation)
- run_quick.sh: fast smoke testing harness
- ENV documentation: docs/ENV_VARS.md

Test Results
✅ quick phase2034: ALL GREEN (MirBuilder internal patterns)
✅ registry phase2160: ALL GREEN (array/map get/set/push/len)
✅ rc-dependent tests → content token verification complete
✅ PREINCLUDE policy: default OFF, point-enable only where needed

Technical Notes
- No INCLUDE by default (maintain minimalism)
- FAIL_FAST=0 in Bring-up contexts only (explicit dev toggles)
- Tag-based route observation ([mirbuilder/min:*], [registry:*])
- MIR structure validation (not just rc parity)

772149c86d Analyzer安定化完了: NYASH_DISABLE_PLUGINS=1復元 + plugin無効化根治 
## 修正内容
1. **hako_check.sh/run_tests.sh**: NYASH_DISABLE_PLUGINS=1 + NYASH_BOX_FACTORY_POLICY=builtin_first追加
2. **src/box_factory/plugin.rs**: NYASH_DISABLE_PLUGINS=1チェック追加
3. **src/box_factory/mod.rs**: plugin shortcut pathでNYASH_DISABLE_PLUGINS尊重
4. **tools/hako_check/render/graphviz.hako**: smart quotes修正（parse error解消）

## 根本原因
- NYASH_USE_PLUGIN_BUILTINS=1が自動設定され、ArrayBox/MapBoxがplugin経由で生成を試行
- bid/registry.rsで"Plugin loading temporarily disabled"の状態でも試行されエラー
- mod.rs:272のshortcut pathがNYASH_DISABLE_PLUGINSを無視していた

## テスト結果
- 10/11 PASS（HC011,13-18,21-22,31）
- HC012: 既存issue（JSON安定化未完）

cef820596f FileBox SSOT設計移行完了: Provider Pattern実装 
## 🎯 目的
FileBoxをSSOT（Single Source of Truth）設計に移行し、
static/dynamic/builtin providerを統一的に扱える基盤を構築。

## ✅ 実装完了（7タスク）

### 1. Provider Lock Global
**File**: `src/runtime/provider_lock.rs`
- `FILEBOX_PROVIDER: OnceLock<Arc<dyn FileIo>>` 追加
- `set_filebox_provider()` / `get_filebox_provider()` 実装

### 2. VM初期化時のProvider選択
**File**: `src/runner/modes/vm.rs`
- `execute_vm_mode()` 冒頭でprovider選択・登録
- ENV（`NYASH_FILEBOX_MODE`, `NYASH_DISABLE_PLUGINS`）対応

### 3. CoreRoFileIo完全実装
**File**: `src/boxes/file/core_ro.rs` (NEW)
- Read-onlyファイルI/O実装
- Thread-safe: `RwLock<Option<File>>`
- Newline正規化（CRLF→LF）

### 4. FileBox委譲化
**File**: `src/boxes/file/mod.rs`
- 直接`std::fs::File`使用 → `Arc<dyn FileIo>` provider委譲
- 全メソッドをprovider経由に変更
- Fail-Fast: write/delete等の非対応操作は明確エラー

### 5. basic/file_box.rs Deprecate
**File**: `src/boxes/file/basic/file_box.rs`
- 120行 → 12行に削減
- `#[deprecated]` マーク + 再エクスポート
- 後方互換性維持

### 6. Feature Flag追加
**File**: `Cargo.toml`
- `builtin-filebox = []` feature追加

### 7. Provider抽象・選択ロジック
**Files**:
- `src/boxes/file/provider.rs` (NEW) - FileIo trait定義
- `src/boxes/file/box_shim.rs` (NEW) - 薄いラッパー
- `src/runner/modes/common_util/provider_registry.rs` (NEW) - 選択ロジック

## 📊 アーキテクチャ進化

**Before**:
```
FileBox (mod.rs) ──直接使用──> std::fs::File
FileBox (basic/)  ──直接使用──> std::fs
```

**After**:
```
FileBox ──委譲──> Arc<dyn FileIo> ──実装──> CoreRoFileIo
                                        ├──> PluginFileIo (future)
                                        └──> BuiltinFileIo (future)
```

## 🔧 技術的成果

1. **Thread Safety**: `RwLock<Option<File>>` で並行アクセス安全
2. **Fail-Fast**: 非対応操作は明確エラー（silent failure無し）
3. **後方互換性**: deprecated re-exportで既存コード維持
4. **環境制御**: `NYASH_FILEBOX_MODE` でランタイム切替

## 📝 環境変数

- `NYASH_FILEBOX_MODE=auto|core-ro|plugin-only`
  - `auto`: プラグインあれば使用、なければCoreRoにフォールバック
  - `core-ro`: 強制的にCoreRo（read-only）
  - `plugin-only`: プラグイン必須（なければFail-Fast）
- `NYASH_DISABLE_PLUGINS=1`: 強制的にcore-roモード

## 🎯 次のステップ（Future）

- [ ] Dynamic統合（plugin_loaderとの連携）
- [ ] BuiltinFileIo実装（feature builtin-filebox）
- [ ] Write/Delete等の操作対応（provider拡張）
