87e477b13e feat(joinir): Phase 188-Impl-2 Pattern 2 (Loop with Conditional Break) implementation
Add Pattern 2 lowerer for `loop { if cond { break } body }` pattern.

New files:
- loop_with_break_minimal.rs (291 lines): JoinIR lowerer for Pattern 2
  - Exit PHI receives values from both natural exit and break path
  - Tail-recursive loop_step function design

Modified files:
- loop_pattern_detection.rs: Add is_loop_with_break_pattern() detection
- mod.rs: Router integration (Pattern 1 → Pattern 2 ordering)

d303d24b43 feat(joinir): Phase 188 JoinInlineBoundary + Pattern 1 working! 🎉
Major milestone: loop_min_while.hako outputs "0 1 2" correctly!

## JoinInlineBoundary (Option D from ChatGPT Pro design review)
- New struct for clean SSA boundary between JoinIR and host function
- JoinIR uses local ValueIds (0,1,2...) - no host ValueId dependency
- Copy injection at entry block connects host → JoinIR values

## Pattern 1 Simple While Loop
- Refactored to use pure local ValueIds
- Removed Pattern1Context dependency on host ValueIds
- Clean separation: lowerer generates, merger connects

## Key Design Principles (Box Theory)
- Box A: JoinIR Frontend (host-agnostic)
- Box B: Join→MIR Bridge (independent functions)
- Box C: JoinInlineBoundary (boundary info only)
- Box D: JoinMirInlineMerger (Copy injection)

## Files Changed
- NEW: inline_boundary.rs - JoinInlineBoundary struct
- control_flow.rs - merge with boundary, void return fix
- simple_while_minimal.rs - pure local ValueIds
- mod.rs - module export

Test: NYASH_DISABLE_PLUGINS=1 ./target/release/hakorune apps/tests/loop_min_while.hako
Output: 0\n1\n2

a7f3200fba wip(joinir): Phase 188-Impl-2 Pattern1Context host variable integration
Work in progress - ValueId mismatch issue needs resolution.

Changes:
- Add Pattern1Context struct with loop_var and value_allocator
- Extract loop variable from condition in cf_loop_pattern1_minimal
- Pass host's ValueId to Pattern 1 lowerer

Problem discovered:
- merge_joinir_mir_blocks() remaps ALL ValueIds
- Host's i (ValueId(2)) gets remapped to ValueId(5)
- ValueId(5) has no initialization → undefined value error

Options under consideration:
- Option A: Pinned Values (don't remap host ValueIds)
- Option B: Inline Block Generation (no JoinModule)
- Option C: Continuation Passing
- Option D: SSA Copy Injection

6d069ba61d feat(joinir): Phase 188 Print instruction + Router integration
- Add MirLikeInst::Print variant for direct output operations
- Implement Print instruction in JSON serialization
- Update simple_while_minimal.rs to use Print instead of BoxCall
- Add Print handling in JoinIR VM bridge and runner
- Add router logic to call Pattern 1 lowerer from main pipeline

Note: Router integration exposes ValueId mismatch issue between
Pattern 1's hardcoded IDs and host function's variables.
This architectural issue needs resolution in next phase.

9ff84596ca fix(joinir): Deterministic HashMap iteration for block allocation
Problem: HashMap iteration order is non-deterministic due to HashDoS
protection (random seeds), causing different block ID assignments on
each run and breaking Pattern 1 execution.

Evidence:
  Run 1: join_func_1:bb2 → bb5
  Run 2: join_func_1:bb2 → bb6  // Different!
  Run 3: join_func_2:bb0 → bb6  // Collision!

Solution: Sort collections before iteration for deterministic ordering:
- Functions sorted by name (alphabetically)
- Blocks sorted by BasicBlockId value (numerically)

Implementation:
- Lines 404-438: Sort functions+blocks in allocation loop
- Lines 493-522: Sort functions+blocks in merge loop

Verification (3 consecutive runs):
  Run 1: join_func_0:bb0→bb3, join_func_1:bb0→bb4...
  Run 2: IDENTICAL 
  Run 3: IDENTICAL 

Impact: Zero performance overhead, guaranteed determinism

2c68b04e49 feat(joinir): Phase 188 Pattern 1 tail call parameter binding
Problem: Tail call conversion (Call→Jump) was failing because:
1. Function parameters were not bound, causing "undefined value" errors
2. Instructions before Call (like BoxCall for print) were being skipped

Solution: Implemented two-pass tail call conversion:
- First pass: Process all instructions, detect tail calls, skip only Call itself
- Second pass: Insert Copy instructions to bind call arguments to parameters

Implementation:
- Lines 517-609: Two-pass approach with tail_call_target tracking
- Lines 588-603: Parameter binding via Copy instructions (arg → param)
- Lines 566-573: Debug logging for BoxCall verification

Example binding:
  Call(loop_step, [i_next])
  → Copy { dst: param_i, src: i_next }
  → Jump(loop_step_entry)

Status: JoinIR firing , parameter binding 
Blocker: Non-deterministic HashMap iteration (next fix)

074fab8459 fix(joinir): Phase 189 HashMap collision bug fix - composite keys
Problem: Multiple JoinIR functions had blocks with identical BasicBlockIds
(e.g., func_0 and func_2 both had BasicBlockId(0)), causing HashMap key
collisions in merge_joinir_mir_blocks(). This corrupted block mappings
and prevented multi-function JoinIR→MIR merge.

Solution: Use composite keys (String, BasicBlockId) instead of simple
BasicBlockId in the global block_map to guarantee uniqueness across
functions.

Implementation:
- Line 399: Changed block_map type to HashMap<(String, BasicBlockId), BasicBlockId>
- Lines 491-507: Added per-function local_block_map for remap compatibility
- Lines 610-616: Updated entry function block_map access to use composite key

Verification:
- Build:  0 errors (34 unrelated warnings)
- Coverage:  100% (all 4 block_map accesses use composite keys)
- Performance:  O(1) HashMap lookups maintained

Phase 189 Status:  COMPLETED (1h vs 4-6h estimate)

5bc0fa861f feat(joinir): Phase 188 Pattern 1 Core Implementation + Phase 189 Planning
Phase 188 Status: Planning & Foundation Complete (100%)

Completed Tasks:
 Task 188-1: Error Inventory (5 patterns identified)
 Task 188-2: Pattern Classification (3 patterns selected)
 Task 188-3: Design (51KB comprehensive blueprint)
 Task 188-4: Implementation Foundation (1,802 lines scaffolding)
 Task 188-5: Verification & Documentation
 Pattern 1 Core Implementation: Detection + Lowering + Routing

Pattern 1 Implementation (322 lines):
- Pattern Detection: is_simple_while_pattern() in loop_pattern_detection.rs
- JoinIR Lowering: lower_simple_while_to_joinir() in simple_while_minimal.rs (219 lines)
  - Generates 3 functions: entry, loop_step (tail-recursive), k_exit
  - Implements condition negation: exit_cond = !(i < 3)
  - Tail-recursive Call pattern with state propagation
- Routing: Added "main" to function routing list in control_flow.rs
- Build:  SUCCESS (0 errors, 34 warnings)

Infrastructure Blocker Identified:
- merge_joinir_mir_blocks() only handles single-function JoinIR modules
- Pattern 1 generates 3 functions (entry + loop_step + k_exit)
- Current implementation only merges first function → loop body never executes
- Root cause: control_flow.rs line ~850 takes only .next() function

Phase 189 Planning Complete:
- Goal: Refactor merge_joinir_mir_blocks() for multi-function support
- Strategy: Sequential Merge (Option A) - merge all functions in call order
- Effort estimate: 5.5-7.5 hours
- Deliverables: README.md (16KB), current-analysis.md (15KB), QUICKSTART.md (5.8KB)

9d29718f03 fix(vm): Phase 173-B using-imported static box method calls
Enable static box method calls for boxes imported via `using` statement.

Root cause: 3 interrelated issues
1. Cross-function ValueId: methodize created singleton with ValueId that
   can't be used across MIR function boundaries
2. Missing registration: using-imported static boxes weren't in
   static_box_decls (only AST-based boxes were registered)
3. Wrong dispatch: method.rs tried InstanceBox dispatch instead of
   MIR function table lookup for static boxes

Fixes:
- unified_emitter.rs: Use receiver=None for StaticCompiler boxes
- vm.rs: Auto-detect and register static boxes from MIR function names
- mod.rs: Add has_static_box_decl() helper
- method.rs: Add MIR function table lookup path for static boxes
- guard.rs: Trust methodize for StaticCompiler boxes without type info

Test: JsonParserBox.toString() via using import now works correctly

c89f08fc52 feat(mir): Phase 84-3 PhiTypeResolver for PHI+Copy graph type inference
- Add PhiTypeResolver box (ChatGPT Pro design) with DFS graph traversal
- Resolve types through PHI + Copy chains with safety conditions
- Case D reduced from 9 to 4 (56% reduction)

Implementation:
- src/mir/phi_core/phi_type_resolver.rs: New box with graph search
- src/mir/phi_core/mod.rs: Add module export
- src/mir/builder/lifecycle.rs: Integrate as P4 (before P3-C)

Algorithm:
- DFS traversal: root → Copy → src / Phi → inputs
- Collect base types (Const/Call/BoxCall/etc definitions)
- Safety: Return Some only when converges to 1 type

Test results:
- Baseline: 504 passed, 30 failed (was 494/33)
- Case D: 4 remaining (from 9, 56% reduction)
- Unit tests: 7/7 passed

Box responsibilities (final):
- GenericTypeResolver: P3-C (generic T/V inference)
- CopyTypePropagator: Copy alias only
- PhiTypeResolver: PHI + Copy graph traversal

Remaining 4 Case D: Special patterns (await/try-catch) need dedicated handling.

Phase 84 progress:

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.

40dfbc68a8 feat(constant): Phase 84-1 Add type annotations for all constant types
Const命令の型アノテーション欠如を根本的に修正。

## 変更内容

5つの emit 関数に型登録を追加:
- emit_integer → MirType::Integer
- emit_bool → MirType::Bool
- emit_float → MirType::Float
- emit_null → MirType::Unknown (Null型が存在しないため)
- emit_void → MirType::Void

emit_string は既に実装済み (Phase 3-A)。

## 成果

- Case D 大幅削減 (詳細は Phase 84 テスト結果で確認)
- 残り 12 件は edge copy / loop break/continue 関連
- Task先生予測の GroupA (Const欠如) を完全解決

## 設計原則

emit_string と同じパターンを踏襲:
```rust
b.value_types.insert(dst, crate::mir::MirType::Integer);
```

## 次のステップ

Phase 84-2: Copy命令型伝播の徹底

  - BoxCall/Call のメソッド名から戻り値型を推論
  - TypeAnnotationBox と同等のマッピングを適用
  - length/size/len → Integer, push → Void, str/substring → String
- lifecycle.rs: P3-D 経路を P3-C の前に挿入
- mod.rs: method_return_hint モジュール登録

## 成果

- Case D 削減: 20 → 16 (4件削減, 20%)
- Unit tests: 5/5 passed

## 設計原則

- 単一責務: P3-D 推論のみ
- TypeAnnotationBox 薄ラップ: 型マッピングの SSOT は TypeAnnotationBox
- 将来移行性: MethodRegistry 導入時も API 不変

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)

b9496000f9 refactor(phase82): DRY化 - Case判定ロジックをヘルパー関数に統一
### リファクタ内容
- 2箇所の callsite で重複していた Case 判定ロジックを統一化
- classify_phi_fallback_case() ヘルパー関数を追加

### 変更前(重複)
- Callsite 1: L321-328 で Case 判定(9行)
- Callsite 2: L378-385 で Case 判定(9行)
- 完全に同一のロジックが重複

### 変更後(DRY)
- classify_phi_fallback_case() ヘルパー関数(14行)
- 各 callsite は 1 行の呼び出しのみ

### メリット
-  DRY原則: ロジック重複削減
-  保守性: Case 分類変更が 1 箇所で完結
-  テスト: ヘルパー関数単独でテスト可能
-  可読性: panic 処理が簡潔に

### 動作確認
- ビルド成功(warning のみ、既存のもの)
- テスト結果: 482 PASS, 34 FAIL(既存の失敗のみ)

1260f2b6d0 feat(phase82): Phase 82-if-phi-retire Step 1-3 dev ガード実装
Phase 82-if-phi-retire Implementation:
- Step 1-3 分析完了: lifecycle.rs 精読 + P3-C カバレッジ突き合わせ
- dev ガード実装: NYASH_PHI_FALLBACK_DISABLED=1 で callsite 封じ

Implementation Details:

1. Analysis Findings (Step 1-2):
   - lifecycle.rs に 2箇所の infer_type_from_phi_with_hint() callsite
   - GenericTypeResolver::resolve_from_phi() と infer_type_from_phi() は同一ロジック
   - Case 分類: A (hint付き), B (P1/P2/P3-A/B hint失敗), D (P3-C 失敗・無駄な再実行)

2. config/env/joinir_dev.rs:
   - phi_fallback_disabled() フラグ追加
   - NYASH_PHI_FALLBACK_DISABLED=1 で有効化

3. lifecycle.rs dev ガード:
   - Callsite 1 (L320-336): instructions 内 Return
   - Callsite 2 (L377-393): terminator Return
   - Case 判定付き panic で関数名・ValueId・Case を出力

Next Steps:
- テスト実行で callsite が実際に呼ばれるか検証
- 結果に基づいて削除計画確定

Documents Created:
- docs/private/roadmap2/phases/phase-82-if-phi-retire/infer_type_from_phi_callsites.md
- docs/private/roadmap2/phases/phase-82-if-phi-retire/step1-3-analysis.md

Goal:
- lifecycle.rs から infer_type_from_phi* 呼び出しを排除
- if_phi.rs 本体削除への道筋を明確化

## 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

Replace HashSet with BTreeSet for CFG predecessors/successors:
- BasicBlock.predecessors: HashSet → BTreeSet
- BasicBlock.successors: HashSet → BTreeSet
- LoopFormOps.get_block_predecessors(): returns BTreeSet
- BasicBlock.dominates(): takes &[BTreeSet<BasicBlockId>]

This ensures deterministic PHI generation and test stability.

Test results:
- loop_with_continue_and_break tests: now deterministic (3/3 same output)
- loopform tests: 14/14 PASS (no regressions)
- merge_exit_with_classification tests: 3/3 PASS

Technical changes (6 files):
- basic_block.rs: BTreeSet types + new() initialization
- loopform_builder.rs: trait signature + 2 mock implementations
- phi_ops.rs: return type
- json_v0_bridge/loop_.rs: return type

lifecycle.rs の型ヒント判定ロジックを箱化モジュール化し、
単一責務原則に基づいたクリーンなアーキテクチャを実現。

## 主な変更

### 新規ファイル

- **type_hint_policy.rs** (237行): 型ヒントポリシー専用モジュール
  - `TypeHintPolicy` 構造体: 型ヒント対象関数の判定
  - `is_target()`: P1/P2/P3-A/P3-B 統合判定
  - `extract_phi_type_hint()`: PHI から型ヒント抽出
  - 7つの単体テスト(パターン別カバレッジ)

### 既存ファイル修正

- **lifecycle.rs**: 60行削減
  - `get_phi_type_hint()` 削除 → `TypeHintPolicy::extract_phi_type_hint()` に移行
  - `is_type_hint_target()` 削除 → `TypeHintPolicy::is_target()` に移行
  - 2箇所の呼び出し箇所を TypeHintPolicy 使用に更新

- **lowering/mod.rs**: type_hint_policy モジュール宣言追加

   - Fail-fast 原則遵守:既存挙動を一切変更しない

2. **lifecycle.rs 呼び出し経路統一** (2箇所)
   - lifecycle.rs:284, 303 で `infer_type_from_phi_with_hint(None, ...)` を呼び出し
   - 現時点では `type_hint=None` でフォールバック動作(既存挙動維持)
   - 将来 Phase 63-6+ で JoinIR からの型ヒント取得を実装

### Test Results

-  IfSelect 全 8 テスト PASS(test_type_hint_propagation_simple 含む)
-  JoinIR 全 57 テスト PASS
-  退行なし確認

### Documentation Updates

## Technical Achievements

- 型ヒント優先インターフェース確立
- lifecycle.rs 呼び出し経路統一
- Phase 63-6+ での段階的型ヒント供給の準備完了

## Deletion Condition Progress

**削除条件達成率**: 2/5 (40%) → **3/5 (60%)** ← Phase 63-5 完了で +20%

1.  JoinIR に `type_hint` 追加(Phase 63-3)
2.  代表ケースで `type_hint` 埋め込み(Phase 63-2)
3.  型ヒント優先に縮退(Phase 63-5)← NEW!
4.  P1 ケースで `type_hint` のみで型決定(Phase 63-6+)

3194cc1e6c feat(joinir): Phase 61-4-F ToplevelOps and production path integration
Phase 61-4-F: Loop-outside If JoinIR production path

Changes:
- F.1: Add ToplevelOps struct implementing PhiBuilderOps for MirBuilder
  - Enables emit_toplevel_phis() to emit PHI instructions via MirBuilder
  - Uses insert_phi_at_head_spanned for proper PHI placement
  - ~70 lines, thin wrapper following box theory

- F.2: Integrate production path with emit_toplevel_phis
  - Replace TODO with actual PHI emission call
  - Build IfShape from branch blocks
  - Log PHI count on dry-run

- Add IfToplevelTest.* to try_lower_if_to_joinir allowed list
  - Fixes function name guard that blocked testing

Note: Pattern matching currently only supports return patterns
(IfMerge/IfSelect). Local variable assignment patterns fall back
to existing PHI generation, which correctly produces valid MIR.

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

## Summary
ArrayExtBox.filter/2 の JoinIR Frontend lowering を完全実装し、
ConditionalMethodCall 命令を導入して filter パターンに対応。
56 JoinIR テスト全て PASS(退行なし)。

## Technical Changes

### 1. ConditionalMethodCall 命令追加
- **新規命令**: `if pred(v) { acc.push(v) }` パターン用
- **構造**: cond が true なら method 実行、false なら no-op
- **MIR 変換**: 4ブロック構造 (cond→then/else→merge)

### 2. AST JSON 拡張
- Break/Continue/FunctionCall に "type" フィールド追加
- ArrayLiteral/MapLiteral に "type" フィールド追加
- JoinIR Frontend 互換性向上

### 3. Expression Handler 拡張

- Call(変数関数呼び出し)を MethodCall に変換

### 4. Loop Pattern Binding 修正
- `BoundExpr::Variable("n")` 問題修正
- `MethodCall { receiver: "arr", method: "size" }` に変更
- external_refs (arr, pred) を step 関数に伝播

### 5. If Statement Handler 拡張
- 条件付き側効果パターン(ケース4)追加
- MethodCall/Method 形式の statement を ConditionalMethodCall に変換

## Files Modified (10 files, +456/-45 lines)
- ast_json.rs: AST JSON "type" フィールド追加
- loop_frontend_binding.rs: n バインディング修正
- control_flow.rs: external_refs params 追加
- loop_patterns.rs: external_refs step 関数伝播

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+.
