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 ✅

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

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

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)

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

✅ 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

feat(phase182): Upgrade 3 JOINIR_TARGETS functions from LowerOnly to Exec
...
Phase 182 implementation: JOINIR_TARGETS expansion for representative paths
## Changes
- Stage1UsingResolverBox.resolve_for_source/5: LowerOnly → Exec (default_enabled: true)
- StageBBodyExtractorBox.build_body_src/2: LowerOnly → Exec (default_enabled: true)
- StageBFuncScannerBox.scan_all_boxes/1: LowerOnly → Exec (default_enabled: true)
## Critical Finding: JOINIR_TARGETS is Loop-Only
Discovered that JOINIR_TARGETS is specifically for LOOP lowering only.
Adding if-lowering functions (like IfSelectTest.test/1) would be counterproductive
because is_loop_lowered_function() exclusion would disable if-lowering entirely.
## Test Results
- 4/5 selfhost loop tests: PASS with NYASH_JOINIR_CORE=1 NYASH_JOINIR_STRICT=1
- 1/5 if-select test: FAIL (requires Phase 183 architectural fix - Option A)
- No regressions in existing functionality
## Phase 183 Recommendation
Implement Option A: Create JOINIR_IF_TARGETS as separate table for if-lowering
functions, avoiding the mutual exclusion problem between loop and if lowering.

fix(json_parser): Eliminate _parse_number() infinite loop with flat control flow

Root cause: Nested-if-in-loop pattern triggered MIR compiler bug
- `if parsing_done == 1 { break }` inside loop caused infinite execution
- Flag variable approach created 2-level nesting that MIR couldn't handle
Fix: Refactored to flat control flow
- Removed `parsing_done` flag variable
- Inverted condition: check exit first (`digit_pos < 0 → break`)
- Direct break without nesting
- Moved `digits` constant outside loop (optimization)
Result:

feat(phase161): Add Analyzer Box design and representative function selection
...
Phase 161 Task 2 & 3 completion:
**Task 2: Analyzer Box Design** (phase161_analyzer_box_design.md)
- Defined 3 core analyzer Boxes with clear responsibilities:
1. JsonParserBox: Low-level JSON parsing (reusable utility)
2. MirAnalyzerBox: Primary MIR v1 semantic analysis (14 methods)
3. JoinIrAnalyzerBox: JoinIR v0 compatibility layer
- Comprehensive API contracts for all methods:
- validateSchema(), summarize_function(), list_phis(), list_loops(), list_ifs()
- propagate_types(), reachability_analysis(), dump methods
- Design principles applied: 箱化, 境界作成, Fail-Fast, 遅延シングルトン
- 5-stage implementation roadmap (Phase 161-2 through 161-5)
- Key algorithms documented: PHI detection, loop detection, if detection, type propagation
**Task 3: Representative Function Selection** (phase161_representative_functions.md)
- Formally selected 5 representative functions covering all patterns:
1. if_simple: Basic if/else with PHI merge (⭐ Simple)
2. loop_simple: Loop with back edge and loop-carried PHI (⭐ Simple)
3. if_loop: Nested if inside loop with multiple PHI (⭐ ⭐ Medium)
4. loop_break: Loop with break statement and multiple exits (⭐ ⭐ Medium)
5. type_prop: Type propagation through loop arithmetic (⭐ ⭐ Medium)
- Each representative validates specific analyzer capabilities
- Selection criteria documented for future extensibility
- Validation strategy for Phase 161-2+ implementation
Representative test files will be created in local_tests/phase161/
(not committed due to .gitignore, but available for development)

feat(hako_check): Improve usability with debug output filtering
...
Phase 1 実装: デバッグ出力ノイズを除去して、実際の lint 結果を見やすく
改善内容:
1. デバッグ出力の自動フィルタリング (デフォルト有効)
- [DEBUG/...] 系の出力を全て除去
- [ControlForm::...] 制御フロー出力を除去
- [BUILDER] MIR ビルダー出力を除去
- [rule/exec] ルール実行出力を除去
2. 環境変数サポート追加
- HAKO_CHECK_DEBUG=1 で詳細デバッグ出力有効化
- HAKO_CHECK_VERBOSE=1 で詳細モード有効化（将来実装予定）
3. 実際の エラーメッセージが明確に見える
- 修正前: 大量の [DEBUG] 出力に埋もれて見えない
- 修正後: [ERROR] メッセージが直接見える
実行例:
```bash
# デフォルト: クリーンな出力
./tools/hako_check.sh file.hako
[ERROR] ❌ MIR compilation error: Undefined variable: void
[lint/summary] failures: 1
# デバッグモード: 詳細情報表示

fix(hako_check): Restore functionality with void-safety guards and option parsing
...
重大バグを2つ修正して hako_check をセルフホスティングソースで使えるように:
1. cli.hako の VoidBox.get() エラー修正 (最優先)
- HakoAnalysisBuilderBox.build_from_source_flags() が void を返す可能性に対応
- フォールバック処理を追加: null/void チェック → Minimal MapBox 生成
- 134行の null チェックが不十分だった
2. hako_check.sh の引数処理修正 (中優先)
- --dead-code, --rules, --no-ast, --debug オプションをサポート
- 以前は --format のみ処理、他はそのまま sed に渡されていた
- while ループで全オプションを正しくパース、EXTRA_ARGS に蓄積
3. cli.hako への EXTRA_ARGS 伝播
- --format "$FORMAT" $EXTRA_ARGS を引数として cli.hako に渡す
結果:
✅ hako_check がセルフホスティングソースで実行可能に
✅ [lint/summary] failures: 1 が出力される（正常動作）
✅ --dead-code オプションが実装済みだが、スクリプトが反映していなかった
次のステップ: デバッグ出力ノイズ削減（デフォルトで [DEBUG/build_block] を非表示）

箱化モジュール化: Phase 173-B の散在した static box 管理を一元化
Before (4箇所に散在):
- static_box_decls: HashMap (AST経由のBox宣言)
- static_boxes: HashMap (実行時シングルトン)
- vm.rs Phase 173-B手動検出コード (~60行)
- method.rs static_box_decls.contains_key() 直接参照
After (StaticBoxRegistry箱に統一):
- declarations: AST経由のBox宣言を登録
- detected_boxes: MIR関数名から自動検出 (using import対応)
- instances: 遅延作成シングルトン
- naming utilities: parse/format関数
Benefits:
- vm.rs: 63行削減 (Phase 173-B手動コード削除)
- 自動検出: using import した static box も対応
- 単一責務: static box lifecycle を1箱に集約
- Fail-Fast: 存在しないBoxへのアクセスは即エラー

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

fix(json_parser): Fix infinite loop by working around MIR nested-if bug
...
🐛 バグ修正: JsonParserBox 無限ループ解消
**問題**:
- `vm step budget exceeded` エラーが発生
- `_parse_number()` で無限ループ
**根本原因**:
- MIR lowering の既知のバグ: ループ内のネスト if-else 文が無限ジャンプチェーンを生成
- bb11 → bb6 → bb4 の無条件ジャンプループ
- PHI 更新が実行されず、ループ変数が更新されない
**修正内容**:
1. `while` → `loop()` 構文に統一（10箇所）
2. ネスト if-else をフラット化（workaround）:
- `_parse_number()`: `ch >= "0" && ch <= "9"` → `digits.indexOf(ch) >= 0`
- `_parse_string()`: ネスト if を分離
- `_unescape_string()`: `ch == "\\" && i + 1 < s.length()` をフラット化
**テスト**:
- json_parser.hako: RC 0 ✅
- ネスト if-else バグを回避して正常動作
**注記**:
- 根本修正（MIR lowering bug fix）は別タスク
- workaround で Phase 173 ブロック解除

feat(hako_check): Phase 154 MIR CFG integration & HC020 dead block detection
...
Implements block-level unreachable code detection using MIR CFG information.
Complements Phase 153's method-level HC019 with fine-grained analysis.
Core Infrastructure (Complete):
- CFG Extractor: Extract block reachability from MirModule
- DeadBlockAnalyzerBox: HC020 rule for unreachable blocks
- CLI Integration: --dead-blocks flag and rule execution
- Test Cases: 4 comprehensive patterns (early return, constant false, infinite loop, break)
- Smoke Test: Validation script for all test cases
Implementation Details:
- src/mir/cfg_extractor.rs: New module for CFG→JSON extraction
- tools/hako_check/rules/rule_dead_blocks.hako: HC020 analyzer box
- tools/hako_check/cli.hako: Added --dead-blocks flag and HC020 integration
- apps/tests/hako_check/test_dead_blocks_*.hako: 4 test cases
Architecture:
- Follows Phase 153 boxed modular pattern (DeadCodeAnalyzerBox)
- Optional CFG field in Analysis IR (backward compatible)
- Uses MIR's built-in reachability computation
- Gracefully skips if CFG unavailable
Known Limitation:
- CFG data bridge pending (Phase 155): analysis_consumer.hako needs MIR access
- Current: DeadBlockAnalyzerBox implemented, but CFG not yet in Analysis IR
- Estimated 2-3 hours to complete bridge in Phase 155
Test Coverage:
- Unit tests: cfg_extractor (simple CFG, unreachable blocks)
- Integration tests: 4 test cases ready (will activate with bridge)
- Smoke test: tools/hako_check_deadblocks_smoke.sh
Documentation:
- phase154_mir_cfg_inventory.md: CFG structure investigation
- phase154_implementation_summary.md: Complete implementation guide
- hako_check_design.md: HC020 rule documentation
Next Phase 155:
- Implement CFG data bridge (extract_mir_cfg builtin)

docs(claude.md): Add hako_check workflow for .hako development (Phase 153)
...
Added new section "🔍 コード品質チェック - hako_check" after selfhost section:
- 5-step workflow with hako_check examples
- Development flow example (edit → run → check → fix loop)
- Check contents: HC011, HC012, HC019 (dead code detection)
- Value: JoinIR-based, safety net for Phase 160+ migration, instant feedback
Integration with selfhost line creates complete .hako development experience:
1. NYASH_USE_NY_COMPILER=1 for fast iteration
2. ./tools/hako_check.sh --dead-code for quality assurance
3. Full verification loop without cargo build overhead

feat(hako_check): Phase 153 - Dead code detection revival (JoinIR version)
...
Implement comprehensive dead code detection for hako_check with JoinIR
integration, following Phase 133/134/152 box-based modularity pattern.
## Key Achievements
1. **Comprehensive Inventory** (`phase153_hako_check_inventory.md`):
- Documented current hako_check architecture (872 lines)
- Analyzed existing HC011/HC012 rules
- Confirmed JoinIR-only pipeline (Phase 124)
- Identified Phase 153 opportunities
2. **DeadCodeAnalyzerBox** (`rule_dead_code.hako`):
- Unified HC019 rule (570+ lines)
- Method-level + box-level dead code detection
- DFS reachability from entrypoints
- Text-based analysis (no MIR JSON dependency for MVP)
- Heuristic-based false positive reduction
3. **CLI Integration** (`cli.hako`):
- Added `--dead-code` flag for comprehensive mode
- Added `--rules dead_code` for selective execution
- Compatible with --format (text/json-lsp/dot)
4. **Test Infrastructure**:
- HC019_dead_code test directory (ng/ok/expected.json)
- `hako_check_deadcode_smoke.sh` with 4 test cases
## Technical Details
- **Input**: Analysis IR (MapBox with methods/calls/boxes/entrypoints)
- **Output**: HC019 diagnostics
- **Algorithm**: Graph-based DFS reachability
- **Pattern**: Box-based modular architecture
- **No ENV vars**: CLI flags only
## Files Modified
