d605611a16 feat(canonicalizer): Phase 143-P0 - parse_number pattern support 
Add parse_number pattern recognition to canonicalizer, expanding adaptation
range for digit collection loops with break in THEN clause.

## Changes

### New Recognizer (ast_feature_extractor.rs)
- `detect_parse_number_pattern()`: Detects `if invalid { break }` pattern
- `ParseNumberInfo`: Struct for extracted pattern info
- ~150 lines added

### Canonicalizer Integration (canonicalizer.rs)
- Parse_number pattern detection before skip_whitespace
- LoopSkeleton construction with 4 steps (Header + Body x2 + Update)
- Routes to Pattern2Break (has_break=true)
- ~60 lines modified

### Export Chain (6 files)
- patterns/mod.rs → joinir/mod.rs → control_flow/mod.rs
- builder.rs → mir/mod.rs
- 8 lines total

### Tests
- `test_parse_number_pattern_recognized()`: Unit test for recognition
- Strict parity verification: GREEN (canonical and router agree)
- ~130 lines added

## Pattern Comparison

| Aspect | Skip Whitespace | Parse Number |
|--------|----------------|--------------|
| Break location | ELSE clause | THEN clause |
| Pattern | `if cond { update } else { break }` | `if invalid { break } rest... update` |
| Body after if | None | Required (result append) |

## Results

- ✅ Skeleton creation successful
- ✅ RoutingDecision matches router (Pattern2Break)
- ✅ Strict parity OK (canonicalizer ↔ router agreement)
- ✅ Unit test PASS
- ✅ Manual test: test_pattern2_parse_number.hako executes correctly

## Statistics

- New patterns: 1 (parse_number)
- Total patterns: 3 (skip_whitespace, parse_number, continue)
- Lines added: ~280
- Files modified: 8
- Parity status: Green ✅

076f193f76 refactor(mir): Extract TypeContext from MirBuilder (Phase 136 follow-up 1/7) 
## Summary
Extract type-related fields into dedicated TypeContext for better code
organization and maintainability. First step of 7-context refactoring plan.

## Changes
- **New**: src/mir/builder/type_context.rs
  - Consolidates value_types, value_kinds, value_origin_newbox
  - Provides clean API for type operations
  - BTreeMap/HashMap as appropriate for determinism

- **Modified**: src/mir/builder.rs
  - Add type_ctx field to MirBuilder
  - Deprecate old fields (backward compat)
  - Add sync helpers for gradual migration
  - Initialize type_ctx in new()

- **Doc**: phase-136-context-box-progress.md
  - Track refactoring progress (1/7 complete)
  - Document design principles
  - Plan next steps (CoreContext)

## Impact
- 16 files with 113 deprecated field usages
- No breaking changes (gradual migration)
- All tests pass (997/997)

## Test Results
✅ cargo build --release (warnings only)
✅ cargo test --release --lib (997 passed)
✅ phase135_trim_mir_verify.sh (PASS)
✅ phase132_exit_phi_parity.sh (3/3 PASS)

## Next Step

455d511187 feat(mir): Phase 136 P0 - ValueId allocator SSOT 徹底（関数内経路から value_gen.next() 掃討） 
## Summary
Eliminates remaining `value_gen.next()` calls from function-context code paths,
unifying all ValueId allocation through `MirBuilder::next_value_id()` SSOT allocator.

## Changes

### 1. Fixed `new_typed_value()` (src/mir/builder.rs:1068)
**Before**: `let id = self.value_gen.next();` (bypasses function context)
**After**: `let id = self.next_value_id();` (respects function context)

This is a public API used in function context, so must use SSOT allocator
to avoid collisions with reserved PHI dsts and function params.

### 2. Fixed test code (src/mir/builder.rs)
**test_shadowing_binding_restore** (lines 1161, 1171):
- Simulates function scope with `push_lexical_scope()`
- Changed to `builder.next_value_id()` for function scope simulation

**test_valueid_binding_parallel_allocation** (lines 1196-1216):
- Tests ValueId/BindingId independence
- Changed to `builder.next_value_id()` with note that Module context fallback preserves test intent

### 3. Verified Module context fallbacks (OK, no change needed)
These already check `current_function.is_some()` and use `value_gen.next()` only as Module context fallback:
- `src/mir/builder/utils.rs:43` - next_value_id() SSOT implementation
- `src/mir/builder/utils.rs:436` - pin_to_slot()
- `src/mir/builder/utils.rs:467` - materialize_local()
- `src/mir/utils/phi_helpers.rs:69` - insert_phi_unified()

## Verification
```bash
rg -n "value_gen\.next\(" src/mir --type rust | grep -v "Module context" | grep -v "//"
# Result: Only comments/docs remain
```

## Acceptance
✅ cargo test --release --lib - 997 passed
✅ phase135_trim_mir_verify.sh - PASS
✅ phase132_exit_phi_parity.sh - 3/3 PASS
✅ All function-context `value_gen.next()` eliminated

## Effect
- **Collision prevention**: No more ValueId collisions between function-level allocations and reserved PHI dsts
- **SSOT compliance**: All ValueId allocation flows through single allocator
- **Contract enforcement**: Phase 135 P1 contract_checks will catch violations immediately

3dc691d39f feat(joinir): Phase 50 Loop Frontend Binding layer 
Phase 50 implements the Loop Frontend Binding layer that maps
actual loop variables to JoinIR Frontend's expected names (i, acc, n).

## Changes

- Add loop_frontend_binding.rs module with:
  - LoopFrontendBinding struct for variable mapping
  - for_print_tokens() and for_array_filter() factory methods
  - generate_local_declarations() for JSON v0 format
  - rename_body_variables() for out → acc renaming

- Integrate binding with cf_loop_joinir_impl:
  - Create binding based on function name
  - Inject i/acc/n Local declarations into JSON v0
  - Use correct JoinIR Frontend type names (Int/Var/Method)

## Limitations Found

JoinIR Frontend doesn't support:
- Field access (me.tokens) - blocks print_tokens
- NewBox (new ArrayBox()) - blocks array_filter

These will be addressed in Phase 51.

a98cc1b945 feat(phi): Step 5-5-F/G - Prevent __pin$ from entering variable_map 
Step 5-5-F: build_assignment() safeguard
- Skip inserting __pin$ temporaries into variable_map
- __pin$ variables are transient compiler-generated temps
- They should not persist across blocks or loops

Step 5-5-G: build_variable_access() safeguard
- Reject attempts to access __pin$ variables from variable_map
- Return clear error: "COMPILER BUG: Attempt to access __pin$ temporary"
- This catches stale __pin$ references early

Root Cause (Corrected):
- NOT BlockId renumbering (as Task initially thought)
- ChatGPT analysis: variable_map/snapshot/carrier have wrong ValueIds
- __pin$ temps were persisting and causing stale references

Test Status: 267 PASS / 1 FAIL (no regressions)

116c6cc74a feat(phi): Step 5-5-E - Fix variable map corruption in build_assignment() 
Root Cause Fixed:
- build_assignment() was calling pin_to_slot(raw_value_id, "@assign")
- This would sometimes return a ValueId from previous __pin$ temporaries
- Result: variable_map["m"] incorrectly pointed to __pin$767$@binop_lhs

Solution:
- REMOVED pin_to_slot() call from build_assignment()
- Direct assignment: value_id = build_expression(value)
- SSA + PHI merges work correctly without explicit pinning

Impact:
- Error location changed: bb363→bb13, ValueId 260→271
- This indicates we've fixed one bug and revealed another
- Test status: 267 PASS / 1 FAIL (no regressions)

Technical Details:
- Task analysis confirmed: Variable map was being corrupted during binop
- The pin_to_slot() caching logic was returning wrong ValueIds
- Simplified code path: expression building creates necessary temporaries

Next: Investigate new ValueId(271) error at BasicBlockId(13)

- 観測専用（NYASH_REGION_TRACE=1で動作、挙動変更なし）

設計理解の深化:
- ValueId(40)問題 = LoopForm v2スコープ契約違反の症状
- 根本解決 = Region観測で無名一時値のスコープまたぎを検出
- 箱理論3原則: 境界明確化/差し替え可能/段階的移行

関連議論:
- ChatGPT提案: Region統一理論でGC/寿命管理の基盤構築
- SlotRegistry: 変数の単一真実源（SSOT）
- 階層構造: FunctionRegion → LoopRegion → IfRegion

次のステップ:
- Phase 1: Region観測（現在）- 非破壊的追加

ff4c4b84c5 📦 Hotfix 3: NewBox ValueId(0) Bug Fix - Module-Level Generator Elimination 
**根本原因**: build_new_expression が value_gen.next() を使用（module-level, starts from 0）

**修正内容**:
- src/mir/builder.rs:738 - Core-13 pure mode NewBox
- src/mir/builder.rs:760 - IntegerBox optimization path
- src/mir/builder.rs:779 - General NewBox emission path

**Before**:
```rust
let dst = self.value_gen.next();  // ❌ Starts from ValueId(0), overwrites param!
```

**After**:
```rust
let dst = self.next_value_id();  // ✅ Respects function param reservation
```

**Impact**:
- ✅ `new ArrayBox()` now gets correct ValueId (e.g., %4 instead of %0)
- ✅ No more parameter ValueId collision
- ✅ SSA form integrity preserved

**Test Result**:
```
Before: %0 = new ArrayBox()  // ❌ Overwrites param %0
After:  %4 = new ArrayBox()  // ✅ Correct allocation
```

**業界標準準拠**:
- ✅ Single Source of Truth: next_value_id() is the only allocator
- ✅ Context-aware allocation (function vs module level)

**Next Issue Discovered**:
- Static box methods need receiver ValueId reservation
- `collect_entries/1` signature shows 1 param, but needs 2 ValueIds (receiver + param)

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
- `src/mir/function.rs`: Parameter reservation
- `src/mir/phi_core/loopform_builder.rs`: Context + validation
- `src/mir/loop_builder.rs`: LoopFormOps impl
- `src/mir/builder/stmts.rs`: Local variable allocation

### 業界標準準拠
- ✅ LLVM IR: Parameters are %0, %1, ...
- ✅ SSA Form: PHI predecessors must exist in CFG
- ✅ Cytron et al. (1991): Parameter reservation principle

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

4f3831c07b fix(builder): 修正案A実装 - emit_unified_call↔emit_box_or_plugin_call再入防止 
🎯 無限再帰の構造的防止（修正案A採用）

## 問題
Phase 2リファクタリング後、stack overflow発生:
```
emit_unified_call (emit.rs:15)
  ↓
emit_box_or_plugin_call (utils.rs:136)
  ↓ line 190
emit_unified_call (emit.rs:15) ← 無限ループ！
```

## 修正案A: 再入防止ガード（採用理由）
- B（Math機能削除）: 対処療法で仕様削減 ❌
- C（"birth"特別扱い）: 局所的修正で他Boxに波及 ❌
- A（構造的再入防止）: 根治的アプローチ ✅

## 実装内容

### 1. MirBuilder にフラグ追加
```rust
pub(super) in_unified_boxcall_fallback: bool
```
役割: RouterPolicyでRoute::BoxCallと決めたフォールバック中マーク

### 2. emit_unified_call 側修正 (emit.rs)
```rust
// Route::BoxCall のときだけ
self.in_unified_boxcall_fallback = true;
emit_box_or_plugin_call(...);
self.in_unified_boxcall_fallback = false;
```

### 3. emit_box_or_plugin_call 側修正 (utils.rs)
```rust
if use_unified_env
    && matches!(route, Route::Unified)
    && !self.in_unified_boxcall_fallback  // ← 追加
{
    // emit_unified_call(...) への再入を防止
}
```

## 構造的改善
- RouterPolicyBox の決定を優先
- emit_unified_call → emit_box_or_plugin_call の一方向化
- 「上位の決定を尊重する」という明確なルール

## 残存課題
⚠️ まだstack overflowが残存（別の再帰ルート存在の可能性）
→ 次のステップでstack trace解析が必要

## テスト状況
- Test 1 (Direct VM): ✅ 成功
- Test 2 (Stage-B): ❌ stack overflow（別ルート調査中）
- Test 3 (MIR verification): ✅ 成功
