0a29f1443e test: Phase 115 if-only call result merge parity (VM + LLVM EXE) 
Phase 115実装 - if分岐内での関数呼び出し結果をマージするパターンを固定

**実装内容**:
- Fixture: phase115_if_only_call_merge_min.hako (expected: 2, 3)
  - if/else両分岐で関数呼び出し f() の結果を変数 v に代入
  - if後にマージされた v を使用（LLVM EXE でのPHI node生成を検証）
- VM smoke: phase115_if_only_call_merge_vm.sh
  - NYASH_DISABLE_PLUGINS=1 HAKO_JOINIR_STRICT=1 で実行
- LLVM EXE smoke: phase115_if_only_call_merge_llvm_exe.sh
  - llvm_exe_runner.sh を利用した標準パリティ検証

**検証結果**:
- VM test: PASS ✅
- LLVM EXE test: PASS ✅
- Phase 114 regression: PASS ✅

**箱化モジュール化の観点**:
- 単一責任: 各smokeは1パターンのみ検証（call result merge）
- 分離: VM/LLVM EXEで独立したテスト（llvm_exe_runner.sh経由）
- Fail-Fast: HAKO_JOINIR_STRICT=1 で不正な制御フローを即座に検出

**関連**:
- Phase 103: If-Only基本パリティ（制御フロー基礎）
- Phase 113: If-Only部分代入パリティ（変数マージ）
- Phase 114: If-Only return+post パリティ（early returnとpost-if文）
- Phase 115: If-Only call result merge パリティ（関数呼び出し結果マージ） ← 今回

80be814fa4 test: Phase 114 if-only return+post parity (VM + LLVM EXE) 
Phase 114 validates that if-only lowering correctly handles cases with:
- Early return in the if-only branch
- Post-if statements that execute on the else path
- Different return values from each path

Fixture: apps/tests/phase114_if_only_return_then_post_min.hako
- Expected output: 7\n2
- f(1): condition true → early return 7
- f(0): condition false → x=1+1=2, return 2

Testing:
- VM backend: phase114_if_only_return_then_post_vm.sh ✅
- LLVM EXE backend: phase114_if_only_return_then_post_llvm_exe.sh ✅
- Regression: Phase 103/113 maintained ✅

Implementation: No new code required - validates existing if-only
exit line routing and post-if statement processing.

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

771bf6b0d1 feat(joinir): Phase 132-P3 - Exit PHI collision early detection 
Added verify_exit_phi_no_collision() to contract_checks.rs for early detection
of ValueId collisions between exit PHIs and other instructions.

Problem detected:
- If exit_phi_builder uses builder.value_gen.next() (module-level) instead of
  func.next_value_id() (function-level), ValueIds can collide:

  Example:
  - bb0: %1 = const 0   (counter init)
  - bb3: %1 = phi ...   (exit PHI - collision!)

Previous behavior:
- Error only detected at LLVM backend runtime
- Cryptic error: "Cannot overwrite PHI dst=1"

New behavior:
- Panic at Rust compile time (debug build)
- Clear error message with fix suggestion:
  "Exit PHI dst %1 collides with instruction in block 0
   Fix: Use func.next_value_id() in exit_phi_builder.rs"

Benefits:
- 🔥 Fail-Fast: Catch errors during Rust compilation, not LLVM execution
- 📋 Clear messages: Exact collision point + fix suggestion
- 🧪 Testable: verify_exit_phi_no_collision() can be unit tested

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
- 47 lines → 8 lines (83% reduction)
- SSOT: builder.vmap owns PHIs
- Fail-Fast: No silent overwrites

**Integration**:
- LLVMBuilder: Added phi_manager
- block_lower.py: Delegated to PhiManager
- tagging.py: Register PHIs with manager

### Documentation
**New Files**:
- docs/development/architecture/exit-phi-design.md
- docs/development/current/main/investigations/phase132-llvm-exit-phi-wrong-result.md
- docs/development/current/main/phases/phase-132/

**Updated**:
- docs/development/current/main/10-Now.md
- docs/development/current/main/phase131-3-llvm-lowering-inventory.md

### Design Principles
- Box-First: Logic encapsulated in classes/methods
- SSOT: Single Source of Truth (builder.vmap for PHIs)
- Fail-Fast: Early explicit failures, no fallbacks
- Separation of Concerns: 3-layer architecture

- Integer/Handle → nyash.console.log_handle(i64)

## 結果
- Case B (loop_min_while): LLVM outputs `0,1,2` ✅
- VM/LLVM完全パリティ達成

5709026812 docs(phase131): Phase 131-3 完了 - LLVM lowering 棚卸し（3ケース） 
Phase 131-3 完了: MIR→LLVM lowering 棚卸し

テスト結果マトリックス:
- Case A (phase87_llvm_exe_min.hako): ✅ PASS (baseline)
- Case B (loop_min_while.hako): ❌ TAG-EMIT (PHI after terminator)
- Case B2 (print(42) simple): ✅ PASS (BoxCall works)
- Case C (llvm_stage3_loop_only.hako): ❌ TAG-EMIT (JoinIR pattern gap)

Critical Bugs:
1. Bug #1: PHI After Terminator (Case B)
   - 原因: function_lower.py が terminator を PHI より先に emit
   - 修正: 4-pass block emission (2-3h)

2. Bug #2: JoinIR Pattern Gap (Case C)
   - 原因: loop(true) { break } パターンが JoinIR 未対応
   - 修正: Pattern 5 設計・実装 (3-4h)

Next Actions:
- P1 (推奨): PHI ordering 修正 → 80% のループを有効化
- P2: JoinIR Pattern 5 → infinite loop 対応

ドキュメント:
- phase131-3-llvm-lowering-inventory.md: 詳細棚卸し結果
- phase87-selfhost-llvm-exe-line.md: LLVM IR parsing error 追記
- CURRENT_TASK.md: phase131-3 参照追加

cd12a2569e feat(llvm): Phase 87 - LLVM exe line SSOT + integration smoke 
Established single pipeline for .hako → executable generation.

SSOT: tools/build_llvm.sh
- Standard procedure: build_llvm.sh input.hako -o output_exe
- Prerequisites: llvm-config-18, llvmlite, LLVM features enabled
- Pipeline: .hako → MIR → LLVM IR → .o → executable

New files:
- docs: phase87-selfhost-llvm-exe-line.md (SSOT procedure doc)
  * Full troubleshooting guide (llvm-config, llvmlite, linking)
  * Advanced usage (custom output, debugging, performance notes)
  * Anti-patterns documentation (no duplication/fragmentation)
- fixture: apps/tests/phase87_llvm_exe_min.hako (5 lines, return 42)
- smoke: integration/apps/phase87_llvm_exe_min.sh
  * Exit code verification (stdout-independent testing)
  * SKIP if LLVM unavailable (graceful degradation)
  * Integration profile only (not in quick)
- index: 10-Now.md, 01-JoinIR-Selfhost-INDEX.md (Phase 87 entries)
- task: CURRENT_TASK.md (Phase 74-87 status update)

Integration smoke: demonstrates full pipeline
- Build: .hako → .o → exe (successful ✅)
- Runtime: Ring0 initialization issue (known limitation, out of scope)
Quick profile: unchanged (integration only, per policy)
Policy: No duplicate build paths, SSOT maintained

987/987 tests PASS (production stable)

Task 80-0: Current status verification
- ✅ 970/970 lib tests PASS (production stable)
- ✅ Core VM smoke tests PASS (json_pp_vm)
- ❌ Phase 79 E2E tests broken (AST API mismatch, out-of-scope)
- ❌ Pre-existing json_lint_vm failure (Pattern2 verifier, out-of-scope)
- **Conclusion**: Phase 80 has ZERO blockers

Task 80-A: SSOT design doc created
- New: docs/development/current/main/phase80-bindingid-p3p4-plan.md (336 lines)
- Pattern3/4 BindingId wiring strategy
- Implementation order: 80-B (P3) → 80-C (P4) → 80-D (E2E)
- Code examples and success metrics
- Fallback detection mechanism (existing log tags)

Design principles (consistent with Phase 74-79):
- Dev-only code (feature-gated)
- Dual-path maintained (BindingId priority + name fallback)
- Structural detection only (NO by-name branching)
- Fail-Fast error handling
- Zero production impact

Updated docs:
- 01-JoinIR-Selfhost-INDEX.md: Phase 79 Activation status
- 10-Now.md: Phase 80 tasks 80-0/80-A complete
- 20-Decisions.md: BindingId migration complete status
- joinir-architecture-overview.md: Phase 79/80 sections

e30116f53d feat(joinir): Phase 171-fix ConditionEnv/ConditionBinding architecture 
Proper HOST↔JoinIR ValueId separation for condition variables:

- Add ConditionEnv struct (name → JoinIR-local ValueId mapping)
- Add ConditionBinding struct (HOST/JoinIR ValueId pairs)
- Modify condition_to_joinir to use ConditionEnv instead of builder.variable_map
- Update Pattern2 lowerer to build ConditionEnv and ConditionBindings
- Extend JoinInlineBoundary with condition_bindings field
- Update BoundaryInjector to inject Copy instructions for condition variables

This fixes the undefined ValueId errors where HOST ValueIds were being
used directly in JoinIR instructions. Programs now execute (RC: 0),
though loop variable exit values still need Phase 172 work.

Key invariants established:
1. JoinIR uses ONLY JoinIR-local ValueIds
2. HOST↔JoinIR bridging is ONLY through JoinInlineBoundary
3. condition_to_joinir NEVER accesses builder.variable_map
