50bb58f2a1 refactor(phi): Phase 57 PHI code reduction 
## Changes

### 57-2-alt: Remove redundant ConservativeMerge call
- phi.rs called ConservativeMerge::analyze twice (once directly,
  once via merge_all_vars)
- Now merge_all_vars returns changed_vars, eliminating redundancy

### 57-3: Delete PhiMergeOps trait (dead code, 17 lines)
- PhiMergeOps trait was defined but never called
- Only impl in loop_builder.rs was unused
- PhiBuilderOps has replaced it

### 57-4: Add responsibility comments to infer_type_from_phi
- Document that it's the "last resort" for type inference
- Specify deletion conditions (JoinIR type annotations)

## Cumulative PHI reduction
- Phase 38: 90 lines
- Phase 40-4.1: 35 lines
- Phase 41-1: 99 lines
- Phase 47: 33 lines
- Phase 57: 17 lines (PhiMergeOps) + optimization
- Total: 365+ lines removed

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)

96849a7ffa docs: AST JSON "kind" vs "type" フィールド設計ドキュメント 
Phase 56 リファクタリング調査の結果、"kind" フィールド削除が不可能と判明。
両フィールドの役割分担と削除不可の理由を明確に文書化。

## 主要発見

- **"kind"**: AST内部用（json_to_ast, PHI生成, ループ変数追跡）
- **"type"**: JoinIR Frontend用（AST lowering）
- **両方必須**: 用途が異なるため並存が設計上必要

## 削除不可の3大理由

1. json_to_ast() の唯一の判定キー
2. PHI生成ロジックに依存（SSA構築）
3. ループ変数処理に使用

## 今後の計画

Phase 60+ で JoinIR Frontend への完全移行後、統一を検討可能。

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.

1e1b2183b2 feat(joinir): Phase 49-4 multi-target routing with graceful fallback 
- Add ArrayExtBox.filter/2 as second JoinIR mainline target
- Fix function name arity: print_tokens is /0 (no implicit me in arity)
- Construct proper JSON v0 format with defs array for JoinIR Frontend
- Add catch_unwind for graceful fallback on unsupported patterns
- Add 3 array_filter tests (smoke, fallback, A/B comparison)
- All 6 Phase 49 tests passing

Dev flags:
- HAKO_JOINIR_PRINT_TOKENS_MAIN=1: JsonTokenizer.print_tokens/0
- HAKO_JOINIR_ARRAY_FILTER_MAIN=1: ArrayExtBox.filter/2

Note: Currently all loops fall back to legacy LoopBuilder due to
JoinIR Frontend expecting hardcoded variable names (i, acc, n).
Full JoinIR integration pending variable scope support in Phase 50+.

  - AST Loop node → Program JSON
  - AstToJoinIrLowerer::lower_program_json() → JoinModule
  - convert_join_module_to_mir_with_meta() → MirModule
  - merge_joinir_mir_blocks() (MVP: logging only)

- Add Phase 49 smoke tests (2 tests):
  - phase49_joinir_mainline_pipeline_smoke
  - phase49_joinir_mainline_fallback_without_flag

- Dev flag: HAKO_JOINIR_PRINT_TOKENS_MAIN=1
- Debug flag: NYASH_JOINIR_MAINLINE_DEBUG=1

MVP limitations:
- Block merge is logging only (Phase 49-3.2 for full impl)
- if-analysis meta is empty (Phase 40+ territory)

- Add LoopScopeShape::from_loop_form() that creates Trio internally
- Remove LoopExitLivenessBox import from loop_to_join.rs
- Switch loop_to_join.rs to use from_loop_form() instead of from_existing_boxes()

This is the first step in absorbing Classifier Trio into LoopScopeShape.
External Trio dependency reduced from 3 boxes to 2 (intake_loop_form only).
