aabb67cdc2 docs: Phase 125 P2-P5 feedback (boxification review) 
Feedback summary:
- 単一責任: EnvLayout / lower_return_value
- SSOT: reads ∩ available_inputs
- Fail-Fast: 構造化エラー + hint
- 段階的投入: 構造のみ（P3 で完成）

Good:
- Single responsibility principle maintained
- SSOT approach for env layout
- Fail-Fast with structured errors
- Graceful degradation (Ok(None))

Improvement proposals:
- P3 wiring clarification
- EnvLayout responsibility scope
- Error hint context-awareness
- Fixture completeness after P3

Next: Phase 125 P3 (available_inputs wiring)

92b3c2afb5 test(joinir): Phase 125 P5 fixture + smoke (VM, structure-only) 
Phase 125 P5: Integration smoke test
- fixture: apps/tests/phase125_if_only_return_readonly_input_min.hako
  - Expected: 7 (return x from reads-only input)
  - Note: Demonstrates structure, full functionality needs P3 wiring
- smoke: tools/smokes/v2/profiles/integration/apps/phase125_if_only_return_input_vm.sh
  - NYASH_JOINIR_DEV=1 HAKO_JOINIR_STRICT=1
  - VM backend only

Test results:
- Phase 125 smoke: PASS (exit code 7)
- Regression (Phase 121-124, 118): PASS
  - phase124_if_only_return_var_vm: PASS
  - phase123_if_only_normalized_semantics_vm: PASS
  - phase121_shadow_if_only_vm: PASS (3/3 tests)
  - phase118_loop_nested_if_merge_vm: PASS

Note:
- P3 (available_inputs wiring) not implemented yet
- Fixture uses simple return (no if-only pattern yet)
- Serves as design document for future P3 implementation
- EnvLayout.inputs will be populated when P3 is complete

4c98313b58 refactor(control_tree): Phase 125 P2-P4 introduce EnvLayout (writes+inputs) + Return(Variable) from inputs 
Phase 125 P2: EnvLayout introduction
- Add EnvLayout struct (writes + inputs)
- from_contract() creates layout from StepTreeContract + available_inputs
- SSOT: inputs = reads ∩ available_inputs (deterministic order)
- No AST inference (don't capture from AST, use provided available_inputs)

Phase 125 P2: Builder env mapping
- lower_if_only_to_normalized: Use EnvLayout to create env map
- writes: Generate ValueId (as before)
- inputs: Reference ValueId from available_inputs (placeholder for P3)
- Function params: writes only (inputs come from outer scope)

Phase 125 P4: Return(Variable) resolution extended
- lower_return_value: Check env (writes + inputs)
- If found: return it (Phase 124 for writes, Phase 125 for inputs)
- If not found: Fail-Fast with structured error + hint
  - Hint: "Pass as param, add to pinned capture, or define before if"
- Phase 125 errors return Ok(None) (out of scope, graceful degradation)

Unit tests:
- test_return_variable_from_env: PASS (Phase 124 regression)
- test_return_variable_out_of_scope: PASS (updated for Phase 125)
- test_return_variable_from_inputs_stub: PASS (P3 not wired yet)
- All 1160 lib tests PASS (no regression)

Note:
- P3 (available_inputs wiring) not implemented yet
- available_inputs is empty BTreeMap (stub)
- EnvLayout.inputs will be empty until P3 is wired
- Structured error tags: [phase125/return/var_not_in_env]

7eec4ec0c8 feat(control_tree): Phase 123 if-only compare+return lowering (Normalized, dev-only) 
Implements Phase 123 P3: If(cond_ast) minimal lowering with graceful degradation.

**What's Implemented**:
- If node lowering with minimal binary comparison (Variable op Integer)
- Supported operators: ==, !=, <, <=, >, >=
- Generates: Compare + Const + Ret structure
- Graceful degradation: returns Ok(None) for unsupported patterns

**Key Design Decisions**:
1. **Graceful Degradation**: Phase 123 limitations return `Ok(None)` instead of failing
   - Allows dev-only mode to coexist with legacy code
   - Error messages prefixed with `[phase123/...]` are caught
2. **Fail-Fast with Structured Errors**: All limitations use structured error codes
   - Format: `[phase123/category/specific]`
3. **Box-First Principles**:
   - `parse_minimal_compare`: Single responsibility parser
   - `verify_branch_is_return_literal`: Branch validation box
   - `lower_if_node`: If lowering box

**Implementation**:
- Added `lower_if_node`: If lowering with minimal compare
- Added `parse_minimal_compare`: Binary comparison parser
- Added `verify_branch_is_return_literal`: Branch validator
- Updated `lower_if_only_to_normalized` return type: `Result<Option<...>, ...>`
- Updated `test_return_variable_out_of_scope`: Verifies graceful degradation
- Added `test_if_minimal_compare`: Verifies If lowering structure

**Tests**: 8 passed (including graceful degradation test)

052040e59c refactor(joinir): extract ExitArgsCollectorBox for jump_args SSOT 
Phase 118 refactoring: Box modularization for exit value collection.

# Changes
- Created `exit_args_collector.rs` with ExitArgsCollectorBox
- Extracted jump_args processing logic from instruction_rewriter.rs
- Implemented SSOT for offset calculation (0 vs 1 legacy layout)
- Added comprehensive unit tests (6 tests, all passing)

# Design
- **Responsibility**: Collects exit PHI inputs + carrier inputs from jump_args
- **SSOT**: Centralized offset calculation logic
- **Fail-Fast**: Validates jump_args length against exit_bindings
- **Phase 118 P2 Contract**: Uses boundary.exit_bindings as SSOT

# Key Features
- Filters ConditionOnly carriers (no exit PHI needed)
- Handles both direct mapping (offset=0) and legacy layout (offset=1)
- Strict mode: Fail-Fast on validation errors
- Non-strict mode: Warns and continues with best effort

# Test Results
- Unit tests: 6/6 PASS
- Phase 118 smoke tests: PASS (VM + LLVM)
- Phase 117 regression: PASS

# Reduced Code Complexity
- instruction_rewriter.rs: ~90 lines → ~25 lines (box call)
- Offset logic: Centralized in ExitArgsCollectorBox

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

- docs/development/current/main/10-Now.md (updated with Phase 117 entry)
- docs/development/current/main/01-JoinIR-Selfhost-INDEX.md (added Phase 117 to index)

**Phase 117 Summary**:
- Verified nested if-only (inner if + outer else) with call merge
- Pattern: 3 call sites (f(1), f(2), f(3)) merge to single variable
- VM/LLVM EXE parity: both produce identical output "2\n3\n4"
- Regression: Phase 116 maintained

**Technical Details**:
- JoinIR Pattern3 (if-only) nested structure validation
- Call merge across nested control flow
- PHI node generation for nested branches
- LLVM EXE plugin integration (StringBox, IntegerBox, ConsoleBox)

**Next Steps**:
Phase 118+ will address more complex nested patterns (if-else nested, loop-if combinations).

ed38aa820a test: Phase 116 if-only keep+call merge parity (VM + LLVM EXE) 
Phase 116 固定: if-only で片側が元値保持、片側が call 結果の merge パターン

## 実装内容

### Fixture
- `apps/tests/phase116_if_only_keep_plus_call_min.hako`
- Expected output: `10\n2`
- Pattern:
  - then側: call結果でvを更新 (`v = f(1)`)
  - else側: 元の値を保持 (`v = 10`)
  - merge地点: 異なるソース（元値 vs call結果）からのPHI

### Smoke Tests
- `phase116_if_only_keep_plus_call_vm.sh` - VM parity
  - output_validator.sh で数値2行 `10\n2` を検証
  - `NYASH_DISABLE_PLUGINS=1 HAKO_JOINIR_STRICT=1`
- `phase116_if_only_keep_plus_call_llvm_exe.sh` - LLVM EXE parity
  - llvm_exe_runner.sh を利用（plugin dlopen/cache/build-all SSOT）
  - llvm_exe_build_and_run_numeric_smoke で検証

## 検証結果

✅ VM smoke: PASS (10\n2)
✅ LLVM EXE smoke: PASS (10\n2)
✅ 回帰 (Phase 115): PASS (2\n3)

## 技術的詳細

### JoinIR Pattern 1 (Simple If)

```
entry_block:
  v = 10
  if flag == 1 goto then_block else exit_block

then_block:
  v = f(1)
  goto exit_block

exit_block:
  v_merged = PHI [v=10 from entry, v=f(1) from then]
  print(v_merged)
```

### PHI接続の重要性
- entry → exit: 元値 (`10`) を直接伝播
- then → exit: call結果 (`f(1)`) を伝播
- PHI: 異なる型のソース（変数 vs call結果）を正しくmerge

LLVM IRでは、これらが適切な型で統一される必要がある。

## Box-First原則の適用

✅ 既存の箱化されたコンポーネントを活用
  - output_validator.sh による出力検証の統一
  - llvm_exe_runner.sh によるLLVM実行の標準化
  - テストインフラの再利用（no reinvention）

## Fail-Fast原則

✅ VM/LLVM両方でエラーを即座に検出
  - `HAKO_JOINIR_STRICT=1` で厳密な検証
  - フォールバック処理なし（エラーは明示的に失敗）

5602aff8a9 refactor(smokes): add output_validator.sh for SSOT numeric assertion 
Output検証をSSOT化して保守性を向上

**新規追加**:
- tools/smokes/v2/lib/output_validator.sh
  - extract_numeric_lines N: 数値行をN行抽出（パターンマッチング）
  - assert_equals_multiline EXPECTED ACTUAL: 複数行期待値と比較
  - validate_numeric_output N EXPECTED OUTPUT: extract + assert の合成Box

**リファクタリング対象** (5ファイル):
- phase103_if_only_vm.sh
- phase103_if_only_early_return_vm.sh
- phase113_if_only_partial_assign_vm.sh
- phase114_if_only_return_then_post_vm.sh
- phase115_if_only_call_merge_vm.sh

**変更内容**:
- 重複パターン `grep -E '^-?[0-9]+$' | head -n N` → `extract_numeric_lines N`
- 比較ロジック → `validate_numeric_output` に統一
- 各smokeは `source output_validator.sh` で共通機能を利用

**検証結果**:
- phase103_if_only_vm: PASS ✅
- phase103_if_only_early_return_vm: PASS ✅
- phase113_if_only_partial_assign_vm: PASS ✅
- phase114_if_only_return_then_post_vm: PASS ✅
- phase115_if_only_call_merge_vm: PASS ✅

**箱化モジュール化の成果**:
- 単一責任: extract_numeric_lines（抽出のみ）、assert_equals_multiline（比較のみ）
- 分離: 各機能が独立したBox（テスト容易性向上）
- 合成: validate_numeric_output が extract + assert を組み合わせ
- Fail-Fast: 全関数でパラメータチェック（明示的エラー）
- 保守性: 検証パターン変更時は output_validator.sh の1箇所のみ修正

**設計原則**:
- Box-First: 機能を箱に切り出して境界を明確化
- SSOT: 数値行抽出と検証ロジックを1箇所に集約
- Fail-Fast: パラメータ不正時は即座にエラー（フォールバックなし）

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
