432fc96082 refactor(joinir): extract IfSumExitMetaBuilderBox for Fail-Fast carrier binding 
Phase 118 refactoring: Box modularization for ExitMeta generation.

# Changes
- Created `exit_meta_builder.rs` with IfSumExitMetaBuilderBox
- Extracted ExitMeta generation logic from loop_with_if_phi_if_sum.rs
- Implemented Fail-Fast contract (carrier name validation)
- Added comprehensive unit tests (5 tests, all passing)

# Design
- **Responsibility**: Builds ExitMeta from carrier name + ValueId
- **Fail-Fast**: Validates carrier names immediately
- **Reusability**: Can be used by other patterns (Pattern 4, etc.)

# Test Results
- Unit tests: 5/5 PASS
- Phase 118 smoke tests: PASS (VM + LLVM)
- Phase 117 regression: PASS

04fdac42f2 feat(mir): Phase 93 P0 - ConditionOnly Derived Slot実装 
## 概要
body-local変数を参照するbreak条件が毎イテレーション正しく再計算される
ConditionOnlyパターンを実装。

## 問題
- `is_ch_match`がConditionBindingで運ばれると初回計算値が固定
- loop header PHIで更新されず、毎周回同じ値がコピーされる
- 結果: `if ch == "b" { break }` が正しく動作しない

## 解決策 (B: ConditionOnly)
1. ConditionOnlyRecipe作成 - Derived slot再計算レシピ
2. setup_condition_env_bindings()でConditionBinding登録停止
3. Pattern2スケジュールでbody-init → break順序保証
4. break条件: ConditionOnlyでは非反転版を使用

## 変更ファイル
- condition_only_emitter.rs (NEW): Derived slot再計算ロジック
- step_schedule.rs: from_env()にhas_condition_only_recipe追加
- loop_with_break_minimal.rs: スケジュール決定でrecipe考慮
- trim_loop_lowering.rs: ConditionOnly用break条件生成追加

## テスト
- step_schedule: 6 tests PASS (新規1: condition_only_recipe_triggers_body_first)
- condition_only_emitter: 3 tests PASS
- Phase 92 baseline: 2 cases PASS
- E2E: /tmp/test_body_local_simple.hako → 出力 "1" ✓

d2972c1437 feat(joinir): Phase 92完了 - ConditionalStep + body-local変数サポート 
## Phase 92全体の成果

**Phase 92 P0-P2**: ConditionalStep JoinIR生成とbody-local変数サポート
- ConditionalStep（条件付きキャリア更新）のJoinIR生成実装
- Body-local変数（ch等）の条件式での参照サポート
- 変数解決優先度: ConditionEnv → LoopBodyLocalEnv

**Phase 92 P3**: BodyLocalPolicyBox + 安全ガード
- BodyLocalPolicyDecision実装（Accept/Reject判定）
- BodyLocalSlot + DualValueRewriter（JoinIR/MIR二重書き込み）
- Fail-Fast契約（Cannot promote LoopBodyLocal検出）

**Phase 92 P4**: E2E固定＋回帰最小化 (本コミット)
- Unit test 3本追加（body-local変数解決検証）
- Integration smoke追加（phase92_pattern2_baseline.sh、2ケースPASS）
- P4-E2E-PLAN.md、P4-COMPLETION.md作成

## 主要な実装

### ConditionalStep（条件付きキャリア更新）
- `conditional_step_emitter.rs`: JoinIR Select命令生成
- `loop_with_break_minimal.rs`: ConditionalStep検出と統合
- `loop_with_continue_minimal.rs`: Pattern4対応

### Body-local変数サポート
- `condition_lowerer.rs`: body-local変数解決機能

- `test_variable_resolution_priority`: 変数解決優先度（ConditionEnv優先）
- `test_undefined_variable_error`: 未定義変数エラー
- 全7テストPASS（cargo test --release condition_lowerer::tests）

### Integration Smoke (+1)
- `phase92_pattern2_baseline.sh`:
  - Case A: loop_min_while.hako (Pattern2 baseline)
  - Case B: phase92_conditional_step_minimal.hako (条件付きインクリメント)
  - 両ケースPASS、integration profileで発見可能

### 退行確認
- ✅ 既存Pattern2Breakテスト正常（退行なし）
- ✅ Phase 135 smoke正常（MIR検証PASS）

## アーキテクチャ設計

### 変数解決メカニズム
```rust
// Priority 1: ConditionEnv (loop params, captured)
if let Some(value_id) = env.get(name) { return Ok(value_id); }
// Priority 2: LoopBodyLocalEnv (body-local like `ch`)
if let Some(body_env) = body_local_env {
    if let Some(value_id) = body_env.get(name) { return Ok(value_id); }
}
```

568619df89 feat(mir): Phase 92 P2-2 - Body-local variable support for ConditionalStep 
Phase 92 P2-2完了：ConditionalStepのcondition（ch == '\\'など）でbody-local変数をサポート

## 主要変更

### 1. condition_lowerer.rs拡張
- `lower_condition_to_joinir`に`body_local_env`パラメータ追加
- 変数解決優先度：ConditionEnv → LoopBodyLocalEnv
- すべての再帰ヘルパー（comparison, logical_and, logical_or, not, value_expression）対応

### 2. conditional_step_emitter.rs修正
- `emit_conditional_step_update`に`body_local_env`パラメータ追加
- condition loweringにbody-local環境を渡す

### 3. loop_with_break_minimal.rs修正
- break condition loweringをbody-local init の**後**に移動（line 411）
- header_break_lowering::lower_break_conditionにbody_local_env渡す
- emit_conditional_step_updateにbody_local_env渡す（line 620）

### 4. header_break_lowering.rs修正
- `lower_break_condition`に`body_local_env`パラメータ追加
- scope_managerにbody-local環境を渡す

### 5. 全呼び出し箇所修正
- expr_lowerer.rs (2箇所)
- method_call_lowerer.rs (2箇所)
- loop_with_if_phi_if_sum.rs (3箇所)
- loop_with_continue_minimal.rs (1箇所)
- carrier_update_emitter.rs (1箇所・legacy)

## アーキテクチャ改善

### Break Condition Lowering順序修正
旧: Header → **Break Cond** → Body-local Init
新: Header → **Body-local Init** → Break Cond

理由：break conditionが`ch == '\"'`のようにbody-local変数を参照する場合、body-local initが先に必要

### 変数解決優先度（Phase 92 P2-2）
1. ConditionEnv（ループパラメータ、captured変数）
2. LoopBodyLocalEnv（body-local変数like `ch`）

## テスト

### ビルド
✅ cargo build --release成功（30 warnings、0 errors）

### E2E
⚠️ body-local promotion問題でブロック（Phase 92範囲外）
- Pattern2はbody-local変数をcarrier promotionする必要あり
- 既存パターン（A-3 Trim, A-4 DigitPos）に`ch = get_char(i)`が該当しない
- **Phase 92 P2-2目標（condition loweringでbody-local変数サポート）は達成**

## 次タスク（Phase 92 P3以降）
- body-local variable promotion拡張（Pattern2で`ch`のような変数を扱う）
- P5b E2Eテスト完全動作確認

## Phase 92 P2-2完了
✅ Body-local変数のcondition lowering対応完了
✅ ConditionalStepでbody-local変数参照可能
✅ Break condition lowering順序修正

d82c332a40 feat(joinir): Phase 135 P0 - ConditionLoweringBox allocator SSOT (ValueId collision fix) 
## Summary
Root cause: ConditionLoweringBox was bypassing ConditionContext.alloc_value (SSOT allocator),
causing ValueId collisions between JoinIR condition params and lowered instructions.

## Changes
1. **ConditionLoweringBox (expr_lowerer.rs)**: Must use ConditionContext.alloc_value
   - Pass &mut ConditionContext to lower_condition (SSOT allocator)
   - Eliminates internal counter usage

2. **Allocator unification (condition_lowerer.rs, method_call_lowerer.rs)**:
   - Accept &mut dyn FnMut() -> ValueId as allocator parameter
   - Ensures all lowering paths use same SSOT allocator

3. **Boundary Copy deduplication (joinir_inline_boundary_injector.rs)**:
   - Deduplicate condition_bindings by dst
   - Fail-Fast if different sources target same dst (MIR SSA violation)

4. **Trim pattern fixes (trim_loop_lowering.rs, trim_pattern_validator.rs, stmts.rs)**:
   - Use builder.next_value_id() instead of value_gen.next() in function context
   - Ensures function-level ValueId allocation respects reserved PHI dsts

## Acceptance
✅ ./target/release/hakorune --verify apps/tests/phase133_json_skip_whitespace_min.hako
✅ Smoke: phase135_trim_mir_verify.sh - MIR SSA validation PASS
✅ Regression: phase132_exit_phi_parity.sh - 3/3 PASS
✅ Regression: phase133_json_skip_whitespace_llvm_exe.sh - compile-only PASS

3f58f34592 feat(llvm): Phase 132-P0 - block_end_values tuple-key fix for cross-function isolation 
## Problem
`block_end_values` used block ID only as key, causing collisions when
multiple functions share the same block IDs (e.g., bb0 in both
condition_fn and main).

## Root Cause
- condition_fn's bb0 → block_end_values[0]
- main's bb0 → block_end_values[0] (OVERWRITES!)
- PHI resolution gets wrong snapshot → dominance error

## Solution (Box-First principle)
Change key from `int` to `Tuple[str, int]` (func_name, block_id):

```python
# Before
block_end_values: Dict[int, Dict[int, ir.Value]]

# After
block_end_values: Dict[Tuple[str, int], Dict[int, ir.Value]]
```

## Files Modified (Python - 6 files)

1. `llvm_builder.py` - Type annotation update
2. `function_lower.py` - Pass func_name to lower_blocks
3. `block_lower.py` - Use tuple keys for snapshot save/load
4. `resolver.py` - Add func_name parameter to resolve_incoming
5. `wiring.py` - Thread func_name through PHI wiring
6. `phi_manager.py` - Debug traces

## Files Modified (Rust - cleanup)

- Removed deprecated `loop_to_join.rs` (297 lines deleted)
- Updated pattern lowerers for cleaner exit handling
- Added lifecycle management improvements

## Verification

- ✅ Pattern 1: VM RC: 3, LLVM Result: 3 (no regression)
- ⚠️ Case C: Still has dominance error (separate root cause)
  - Needs additional scope fixes (phi_manager, resolver caches)

## Design Principles

- **Box-First**: Each function is an isolated Box with scoped state
- **SSOT**: (func_name, block_id) uniquely identifies block snapshots
- **Fail-Fast**: No cross-function state contamination

## Known Issues (Phase 132-P1)

Other function-local state needs same treatment:
- phi_manager.predeclared
- resolver caches (i64_cache, ptr_cache, etc.)
- builder._jump_only_blocks

447d4ea246 feat(llvm): Phase 132 - Pattern 1 exit value parity fix + Box-First refactoring 
## Phase 132: Exit PHI Value Parity Fix

### Problem
Pattern 1 (Simple While) returned 0 instead of final loop variable value (3)
- VM: RC: 3 ✅ (correct)
- LLVM: Result: 0 ❌ (wrong)

### Root Cause (Two Layers)
1. **JoinIR/Boundary**: Missing exit_bindings → ExitLineReconnector not firing
2. **LLVM Python**: block_end_values snapshot dropping PHI values

### Fix
**JoinIR** (simple_while_minimal.rs):
- Jump(k_exit, [i_param]) passes exit value

**Boundary** (pattern1_minimal.rs):
- Added LoopExitBinding with carrier_name="i", role=LoopState
- Enables ExitLineReconnector to update variable_map

**LLVM** (block_lower.py):
- Use predeclared_ret_phis for reliable PHI filtering
- Protect builder.vmap PHIs from overwrites (SSOT principle)

### Result
- ✅ VM: RC: 3
- ✅ LLVM: Result: 3
- ✅ VM/LLVM parity achieved

## Phase 132-Post: Box-First Refactoring

### Rust Side
**JoinModule::require_function()** (mod.rs):
- Encapsulate function search logic
- 10 lines → 1 line (90% reduction)
- Reusable for Pattern 2-5

### Python Side
**PhiManager Box** (phi_manager.py - new):
- Centralized PHI lifecycle management

233a49d902 feat(joinir): Phase 131-11 A-C - InfiniteEarlyExit パターン追加（検出部分） 
## Step A: Feature Detection
- LoopPatternKind::InfiniteEarlyExit (Pattern 5) 追加
- LoopFeatures::is_infinite_loop フィールド追加
- detect_infinite_loop() で loop(true) 検出

## Step B: Classification Logic
- classify() を更新: Pattern 5 を Pattern 4 より優先
- Pattern 4 を狭化: has_continue && !has_break のみ
- 誤ルーティング完全除去

## Step C: Pattern Module
- pattern5_infinite_early_exit.rs 新規作成
- Fail-Fast 設計: 超狭い shape guard
- lowering はスケルトン（Phase 131-11-D で実装）

## 動作確認
- Pattern 5 正常検出 ✅
- Shape guards 動作（1 break, 1 continue, 1 carrier）✅
- Pattern 4 誤ルーティング回避 ✅

b7f7882558 feat(joinir): Phase 79 Activation - BindingId wiring operational (dev-only) 
Phase 79 の最終段階：BindingId を ExprLowerer に配線し、end-to-end で動作確認。

Key changes:
- ExprLowerer wiring:
  - scope_resolution.rs: build_condition_env_from_scope_with_binding() (BindingId-aware)
  - expr_lowerer.rs: lower_condition() uses BindingId priority lookup

- ConditionEnv extension:
  - register_loop_var_binding(): Loop var BindingId→ValueId registration
  - register_condition_binding(): Condition-only carrier BindingId→ValueId registration

- Pattern2 integration:
  - pattern2_with_break.rs: Loop var registration (Line 116-128)
  - pattern2_with_break.rs: Carrier role-based registration (Line 381-425)
  - Debug logging: [phase79] tags for registration, [binding_pilot/hit] for lookup success

- E2E tests (normalized_joinir_min.rs, debug-only):
  - test_phase79_digitpos_bindingid_lookup_works(): DigitPos pattern verification
  - test_phase79_trim_bindingid_lookup_works(): Trim pattern verification

Result: BindingId lookup actually works end-to-end
- Promoted carriers resolve via BindingId, not string hacks
- Debug: NYASH_JOINIR_DEBUG=1 shows [phase79] Registered loop var BindingId, [binding_pilot/hit] BindingId(1) -> ValueId(100)

Tests: 1025/1025 lib PASS
Design: dev-only feature-gated, dual-path maintained (BindingId priority + name fallback)

Phase 74-79 complete: BindingId migration fully operational
- Infrastructure (74-76): BindingId type, binding_map, 3-tier lookup, promoted_bindings map
- Implementation (77): DigitPos/Trim populate, legacy deprecate
- Refactoring (78-79 Refactoring): PromotedBindingRecorder, Detector/Recorder split
- Activation (80 Foundation + 79 Activation): CarrierBindingAssigner + ExprLowerer wiring

8b48bec962 feat(joinir): Phase 78 - BindingId infrastructure for promoted carriers (dev-only) 
Phase 78 adds infrastructure to assign BindingIds to synthetic promoted
carriers (e.g., is_digit_pos, is_ch_match), enabling type-safe promoted
variable lookup without string-based naming conventions.

Key Changes:
1. CarrierVar.binding_id field (dev-only):
   - Added Option<BindingId> to track BindingId for each carrier
   - Updated all constructors and struct instantiations

2. CarrierBindingAssigner Box (new file, 273 lines):
   - Allocates BindingIds for promoted carriers via builder.allocate_binding_id()
   - Records original → promoted mapping in promoted_bindings
   - Sets binding_id field on promoted CarrierVar
   - Includes 3 comprehensive unit tests

3. ConditionEnv.register_carrier_binding() (new method):
   - Registers carrier BindingId → ValueId mappings
   - Enables type-safe lookup via binding_id_map

4. Logging cleanup:
   - Gated 6 eprintln! statements with NYASH_JOINIR_DEBUG
   - Unified logging tags to [binding_pilot/*]

Design Decisions:
- Promoters create CarrierInfo, lowering code assigns BindingIds
- CarrierBindingAssigner called from Pattern2/4 lowering (has builder access)
- Clear documentation prevents misuse (promoters lack builder access)

Files modified (18):
- carrier_info.rs: binding_id field added to CarrierVar
- carrier_binding_assigner.rs: New Box for BindingId allocation
- condition_env.rs: register_carrier_binding() method
- mod.rs: Module exports
- pattern2_with_break.rs, pattern4_with_continue.rs: Updated for binding_id
- loop_body_*_promoter.rs: Logging cleanup + binding_id in structs
- phase78-bindingid-promoted-carriers.md: Architecture documentation

Tests: 970/970 PASS (zero regressions)
Status: Infrastructure complete, integration deferred to Phase 79

Next Phase: Wire CarrierBindingAssigner in Pattern2/4 lowering + E2E tests

- DigitPosPromoter: Added binding_map field and record_promoted_binding() calls
- TrimLoopHelper: Added binding_map field for ch → is_ch_match tracking
- Pattern2/4: Wired binding_map from builder.binding_map to promoters
- Legacy deprecation: Added #[deprecated] to resolve_promoted_join_id()
- Dual-path design: BindingId priority + name fallback maintained

Files modified (8):
- pattern2_with_break.rs, pattern4_with_continue.rs: binding_map wiring
- trim_loop_lowering.rs: Trim promoter integration
- carrier_info.rs: Deprecation warnings
- scope_manager.rs: Deprecated fallback paths
- loop_body_carrier_promoter.rs: Trim binding_map support
- loop_body_cond_promoter.rs: Orchestrator updates
- loop_body_digitpos_promoter.rs: DigitPos binding_map support

Tests: 958/958 PASS (zero regressions)
Design: Type-safe BindingId mapping replaces string-based promoted variable resolution

Phase 78+ will delete deprecated code (~50 lines) and make binding_map required.

11e68203c8 feat(joinir): Phase 76 - promoted_bindings map (dev-only) 
Phase 76 introduces type-safe promotion tracking via promoted_bindings
(BindingId→BindingId map). Replaces fragile string matching hacks with
compiler-checked identity mapping.

Changes:
- carrier_info.rs: Added promoted_bindings field and resolution methods
- pattern4_carrier_analyzer.rs: Updated for BindingId integration
- pattern_pipeline.rs: Carrier resolution via promoted_bindings
- loop_with_break_minimal/tests.rs: Added promoted_bindings tests
- normalized/fixtures.rs: Extended with Phase 76 fixtures

Tests: 5/5 new unit tests PASS (record/resolve/merge/default/overwrite)
Tests: lib 958/958 PASS, normalized_dev 54/54 PASS (no regressions)

Design: Dual-path (BindingId OR name) enables gradual Phase 77+ transition.

c18dde238a feat(joinir): Phase 75 - BindingId pilot lookup (dev-only) 
Phase 75 pilots BindingId-based variable lookup in the ScopeManager and
ConditionEnv components. Demonstrates "BindingId priority → name fallback"
strategy with comprehensive testing and zero production impact.

Changes:
- scope_manager.rs: Added lookup_with_binding() trait method
- condition_env.rs: Implemented resolve_var_with_binding() with 3-tier fallback
- expr_lowerer.rs: Integrated pilot lookup paths
- condition_lowering_box.rs: Updated with BindingId support

Tests: 3/3 new pilot tests PASS (priority/fallback/legacy)
Tests: lib 958/958 PASS, normalized_dev 54/54 PASS (no regressions)

Design: Feature-gated with normalized_dev, enables Phase 76 expansion.

851bf4f8a5 design(joinir): Phase 73 - ScopeManager BindingId Migration Design + PoC 
Phase 73 plans migration from name-based to BindingId-based scope management
in JoinIR lowering, aligning with MIR's lexical scope model.

Design decision: Option A (Parallel BindingId Layer) with gradual migration.
Migration roadmap: Phases 74-77, ~8-12 hours total, zero production impact.

Changes:
- phase73-scope-manager-design.md: SSOT design (~700 lines)
- phase73-completion-summary.md: Deliverables summary
- phase73-index.md: Navigation index
- scope_manager_bindingid_poc/: Working PoC (437 lines, dev-only)

Tests: 6/6 PoC tests PASS, lib 950/950 PASS
Implementation: Parallel layer (no changes to existing code paths)

c2df1cacf6 feat(joinir): Phase 70-B - Multihop Relay Passthrough Support (dev-only) 
Phase 70-B relaxes runtime guard from "always error" to "unsupported only".
Adds structural detection (is_supported_multihop_pattern) to distinguish:
- Simple passthrough (no self-updates): ACCEPT
- Complex patterns (self-conflict, etc): REJECT with [ownership/relay:runtime_unsupported]

Changes:
- plan_validator.rs: +is_supported_multihop_pattern() method + unit tests
- normalized_joinir_min.rs: +2 integration tests for passthrough/rejection
- phase70-relay-runtime-guard.md: Phase 70 series status table added

Tests: normalized_dev 52/52 PASS, lib 950/950 PASS
Design: Structural detection only (no by-name branching)

db9c9055fa obs(joinir): Phase 72 - PHI Reserved Region Observation Complete 
## Summary
Observed PHI dst ValueId distribution to determine if verifier can enforce
reserved region (0-99). **Conclusion: Verifier strengthening NOT recommended.**

## Key Finding
PHI dst allocation does NOT architecturally respect reserved region:
- PHI dst comes from `builder.next_value_id()` (host MirBuilder)
- Reserved region (0-99) is a JoinValueSpace contract for JoinIR lowering
- These are separate allocation pools with no enforcement mechanism
- Current stability is accidental (ValueId allocation ordering)

## Evidence
Manual verification (`apps/tests/loop_min_while.hako`):
- PHI dst = %3 (ValueId(3)) ✅ in reserved region
- Works because PHI allocated early in function (0-20 typical)
- JoinValueSpace allocates high (100+, 1000+)
- Accidental separation, not enforced

## Implementation
Added observation infrastructure (debug-only):
- `src/mir/join_ir/verify_phi_reserved.rs` (266 lines)
  - PHI dst observer with distribution analyzer
  - Region classifier (Reserved/Param/Local)
  - Human-readable report generator
- Instrumentation at PHI allocation points:
  - loop_header_phi_builder.rs:94, 151
  - Debug-only `observe_phi_dst()` calls

## Test Results
- Unit tests: ✅ 4/4 PASS (verify_phi_reserved module)
- Lib tests: ✅ 950/950 PASS, 56 ignored
- Normalized tests: ✅ 54/54 PASS
- Manual verification: ✅ PHI dst in 0-99 observed

## Decision: Document, Don't Enforce
**Rationale**:
1. No architectural mechanism to enforce PHI dst ∈ [0, 99]
2. Adding verifier creates false assumptions about allocation order
3. Current system stable through separate pools (950/950 tests)
4. Future architectural fix possible (Phase 73+) but not urgent

## Documentation
- PHASE_72_SUMMARY.md: Executive summary and implementation record
- phase72-phi-reserved-observation.md: Detailed findings and analysis
- CURRENT_TASK.md: Phase 72 completion entry

## Next Steps
- Phase 73: Update architecture overview with Phase 72 findings
- Optional: Explicit PHI reserved pool (future enhancement)
