c5abf62350 docs(phase84): Add Phase 84-3 analysis and Phase 84-4 recommendations
Task agent investigation results after Phase 84-3 completion.

Remaining 4 Case D analysis:
- test_lowering_await_expression: await construct
- mir_lowering_of_qmark_propagate: QMark (?) construct
- mir_stage1_cli_emit_program_min_*: Stage1Cli type inference (2 tests)

Root cause (unified): BoxCall/Await/QMark return types not registered in value_types

Phase 84-4 implementation recommendations:
- Phase 84-4-A: dev fallback (0.5 days) - immediate unblock
- Phase 84-4-B: BoxCall type registration (1-2 days) - solves 3 cases
- Phase 84-4-C: Await type special handling (0.5 days) - solves 1 case

Documents added:
- phase84-3-summary.md: Reduction results and Phase 84-4 recommendations
- phase84-3-remaining-4-analysis.md: Detailed analysis of each test
- phase84-4-implementation-recommendation.md: Implementation guide with code examples
- phase84-index.md: Phase 84 overall index and roadmap
- phase84-3-final-report.md: Complete report with executive summary

Cumulative results:
- Phase 82: 12 cases
- Phase 84-2: 9 cases (25% reduction)
- Phase 84-3: 4 cases (56% reduction)
- Total: 67% reduction achieved (12 → 4)

4ef5eec162 feat(mir): Phase 84-2 CopyTypePropagator for Copy chain type propagation
- Add CopyTypePropagator box (ChatGPT Pro design) for fixed-point
  Copy instruction type propagation
- Integrate into lifecycle.rs before return type inference
- Case D reduced from 12 to 9 (25% reduction)

Implementation:
- src/mir/phi_core/copy_type_propagator.rs: New box with fixed-point loop
- src/mir/phi_core/mod.rs: Add module export
- src/mir/builder/lifecycle.rs: Call propagator before return inference

Test results:
- Baseline: 494 passed, 33 failed (was 489/34)
- Case D: 9 remaining (from 12)
- Unit tests: 4/4 passed

Remaining 9 Case D breakdown:
- GroupA: Loop Edge Copy (7 cases) - PHI incoming needs Copy trace
- GroupB: Multi-level PHI (2 cases) - Recursive PHI resolution needed

Phase 84-3 will address GroupA with Edge Copy tracing in GenericTypeResolver.

0771945735 docs: Add Phase 84 Case D detailed analysis
Task先生による残り15件のCase D詳細分析レポート。

## 主要発見

**根本原因**: Const命令の型アノテーション欠如(58-67%)
- Integer/Bool/Float/Null/Void定数が型登録されていない
- String定数は既に実装済み

## 分類

- GroupA: Const命令型アノテーション欠如(14-16件、58-67%)
- GroupB: Copy命令型伝播不足(6-8件、25-33%)
- GroupC: PHI命令型推論不足(4-6件、17-25%)
- GroupD: その他の命令型(2-4件)

## Phase 84-1 推奨

`src/mir/builder/emission/constant.rs` に5行追加で90%削減可能。

## ドキュメント

- phase84-case-d-detailed-analysis.md: 全24件の詳細分析

be38e4c272 fix(joinir): Phase 82-5 lifecycle.rs return type inference bug fix
**Problem**: lifecycle.rs walked bb.instructions before checking bb.terminator,
causing it to infer types from intermediate values like `%1 = const void` instead
of the actual return value.

**Solution**: Remove instructions walking entirely, only check terminator Returns.
This ensures we infer type from the actual return value (e.g., `ret %3`).

**Impact**:
- Case D failures: 51 → 20 (60% reduction! 31 eliminated)
- Removed ~55 lines of redundant instructions walking
- All remaining 20 Case D are genuine GenericTypeResolver coverage issues

**Files Modified**:
- src/mir/builder/lifecycle.rs: Remove instructions loop, only check terminator

**Test Results**:
- Baseline: 483 passed, 33 failed
- With NYASH_PHI_FALLBACK_DISABLED=1: 463 passed, 53 failed (20 Case D panics)
- All remaining Case D are in `main` functions (genuine, not bugs)

e656958033 feat(env): Phase 71-73 - SSA fix + Stage-3 ENV consolidation
## Phase 71-SSA: StageBDriverBox birth warning 解消
- Fixed false-positive dev verify warning for static boxes
- StageBDriverBox is a static box, so it doesn't follow NewBox→birth pattern
- Modified lifecycle.rs to skip StageBDriverBox from birth() requirement

## Phase 73-A: Stage-3 legacy ENV 統一化
- Consolidated NYASH_PARSER_STAGE3 and HAKO_PARSER_STAGE3 → NYASH_FEATURES=stage3
- Updated 20 test files (46 direct replacements)
- Special handling for parser_stage3.rs compat layer and mir_static_main_args_loop.rs
- All test files now use unified NYASH_FEATURES=stage3

## Phase 72-73: ENV inventory documented
- Created phase72-73-env-inventory.md with complete usage analysis
- Identified 113 direct ENV reads requiring SSOT consolidation
- Prioritized Phase 72 (JoinIR EXPERIMENT SSOT) and Phase 73 (Stage-3 cleanup)

## Phase 74-SSA: Minimal reproduction for static box delegation
- Created parser_box_minimal.hako and ssa_static_delegation_min.hako
- Investigated spawn failure in selfhost compiler (arguments too long)
- Root cause: NYASH_NY_COMPILER_EMIT_ONLY=1 defaults to emit-only mode

4b3eb6b3a9 feat(phase71-ssa): SSA undef 完全解消達成!(4件→0件)
## Phase 71-SSA SSA undef 削減 完全達成!

### 🎉 成果
- **SSA undef**: 4件 → **0件** (100%解消!)
- **所要時間**: 約2時間 (Task先生調査 + 実装 + 検証)
- **修正ファイル**: 3ファイル (.hako実装のみ、MIR/SSAビルダー不変)

### 🔍 根本原因 (Task先生による徹底分析)
**ValueId(272) = StringHelpers.starts_with_kw/3 の戻り値**
- static boxの委譲でValueIdマッピング失敗
- 引数パラメータ設定ログが一切出力されず
- 別関数の戻り値ValueIdが誤って引数として参照される

### 🛠️ 修正内容

**修正1: ParserStringUtilsBox.trim (Quick Win)**
- L76: `StringHelpers.skip_ws` → `ParserStringUtilsBox.skip_ws`
- 効果: SSA undef 4件 → 2件
- 副次効果: Main._parse_number/ParserBox.parse_block2 消滅

**修正2: ParserCommonUtilsBox.trim (修正案A)**
- L50-69: 委譲を廃止、直接実装に変更
- FuncScannerBox.trimの成功パターンを適用

**修正3: ParserBox.trim (修正案A)**
- L81-98: 委譲を廃止、直接実装に変更
- 効果: 残り2件のSSA undef完全解消

###  検証結果
```bash
grep -c 'ssa-undef-debug' logs/selfhost/stageb_20251202_111409_2674670.log
# 出力: 0 ← 🎉 完全解消!
```

### 📊 SSA undef 推移
| フェーズ | 件数 | 詳細 |
|---------|------|------|
| Phase 71初回 | 4件 | trim×2, _parse_number, parse_block2 |
| Quick Win後 | 2件 | trim×2 (予想外: 他2件消滅) |
| 修正案A後 | **0件** | 🎉 **完全解消!** |

### 🎯 残存課題 (次フェーズ)
1. dev verify警告: 1件 (StageBDriverBox birth)
2. Program JSON未出力: extract_ok=0 (rc=0だが行なし)

### 💡 重要な教訓
- static boxの委譲は危険 (ValueIdマッピング失敗)
- 静的呼び出し (BoxName.method) が SSA-friendly
- 成功パターン (FuncScannerBox.trim) の積極活用

### 📝 ドキュメント
- 詳細レポート: phase71-ssa-trim-fix-20251202.md

f4044c56cb refactor(phase62): Delete phi_input_collector.rs (-384 lines)
Phase 62前倒し: PhiInputCollectorの物理削除

Changes:
- Delete src/mir/phi_core/phi_input_collector.rs (-384 lines)
- Inline PhiInputCollector logic in json_v0_bridge/lowering/loop_.rs
  - sanitize: BTreeMap dedup + sort
  - optimize_same_value: check all inputs for same value
- Remove mod declaration in phi_core/mod.rs

Rationale:
- PhiInputCollector already inlined in Phase 59 (loopform_builder.rs)
- Last remaining usage was in JSON v0 Bridge
- Simple inline preserves exact behavior

Impact:
- -384 lines (Box + tests)
- No behavior change (inline equivalent)
- Build & test pass

3af98964ed feat(joinir): Phase P2-P4 Loop Pattern boxification
- P2: Create loop_patterns/ module structure
  - common.rs: shared helpers (ParsedProgram, LoopContext, etc.)
  - simple.rs: generic loop lowering
  - filter.rs, print_tokens.rs: delegate to simple
  - break_pattern.rs, continue_pattern.rs: new modules

- P3: Create LoopFrontendBinding layer
  - Separate function name detection from pattern lowering
  - detect_loop_pattern() for pattern classification

- P4: Break/Continue pattern migration
  - Move Break/Continue handling from loop_patterns_old.rs
  - Add LoopPattern::Break and LoopPattern::Continue variants

- Design: 3-layer architecture
  - LoopFrontendBinding: function name → LoopPattern
  - loop_patterns: LoopPattern → JoinIR
  - Bridge/VM: Box semantics

All 56 JoinIR tests pass.

fd83903f87 feat(joinir): Phase P1 If Handler boxification - 40% code reduction
## Summary
Refactored loop-internal If statement handling into a boxified module
structure, achieving 154-line reduction (40%) from stmt_handlers.rs
with zero regression.

## Implementation
- Created if_in_loop/ module (9 files, ~480 lines)
  - pattern.rs: IfInLoopPattern enum (5 variants)
  - lowering/{empty,single_var_then,single_var_both,conditional_effect,unsupported}.rs
- Replaced lower_if_stmt_in_loop() (154 lines) with lower_if_stmt_in_loop_boxified()
- Made StatementEffect pub(crate) for module visibility

## Pattern Classification
1. Empty: condition-only check (no side effects)
2. SingleVarThen: if { x = a } → x = cond ? a : x
3. SingleVarBoth: if { x = a } else { x = b } → x = cond ? a : b
4. ConditionalEffect: if pred(v) { acc.push(v) } (filter pattern)
5. Unsupported: complex cases (Phase 54+)

## Test Results
 56 JoinIR tests PASSED (0 failed, 0 regression)
 Build successful (1m 02s)
 Improved maintainability (easier to add new patterns)

## Files Changed
- src/mir/join_ir/frontend/ast_lowerer/
  - if_in_loop/ (9 new files)
  - mod.rs (+2 lines: module + pub use)
  - stmt_handlers.rs (-154 lines: 40% reduction)
- CURRENT_TASK.md (+5 lines: Phase P1 記録)
- docs/development/refactoring/p1-if-handler-boxification-plan.md (new)

6bb6f38a1c feat(joinir): Phase 51 Field access / NewBox 式タイプ拡張
JoinIR Frontend の式タイプを拡張し、Field access と NewBox のパースと
MIR 変換をサポート。

## 新機能

### Field access (me.tokens 等)
- expr.rs に "Field" タイプハンドラ追加
- JoinInst::FieldAccess バリアント追加
- MIR 変換: FieldAccess → BoxCall (getter pattern)

### NewBox (new ArrayBox() 等)
- expr.rs に "NewBox" タイプハンドラ追加
- JoinInst::NewBox バリアント追加
- MIR 変換: NewBox → MirInstruction::NewBox

## 修正ファイル

- src/mir/join_ir/mod.rs: JoinInst 拡張
- src/mir/join_ir/frontend/ast_lowerer/expr.rs: パース対応
- src/mir/join_ir_vm_bridge/convert.rs: MIR 変換
- src/mir/join_ir_runner.rs: ハンドラ追加
- src/mir/join_ir/json.rs: JSON シリアライズ

## 注意

print_tokens/array_filter の JoinIR 完走には Phase 52 で
JSON 生成側 (LoopFrontendBinding) の修正が必要。

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.
