# CURRENT_TASK (moved)
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 - NEW: docs/development/current/main/phase153_hako_check_inventory.md - NEW: tools/hako_check/rules/rule_dead_code.hako - MOD: tools/hako_check/cli.hako - NEW: tools/hako_check/tests/HC019_dead_code/ - NEW: tools/hako_check_deadcode_smoke.sh - MOD: CURRENT_TASK.md ## Next Steps - Phase 154+: MIR CFG integration for block-level detection - Phase 160+: Integration with .hako JoinIR/MIR migration 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

### 状況（SSOT）
- 現行の入口: `docs/development/current/main/10-Now.md`
- 次の候補: `docs/development/current/main/30-Backlog.md`
refactor(joinir): unify boundary join_inputs SSOT (pattern4/6/7) Apply Phase 256.8 SSOT fix to Pattern4/6/7: - Use join_module.entry.params.clone() instead of hardcoded ValueIds - Add fail-fast validation for params count mismatch - Remove ValueId(0), ValueId(PARAM_MIN + k) patterns - Clean up unused PARAM_MIN imports This prevents entry_param_mismatch errors structurally and maintains consistency with Pattern2/3. Changes: - pattern4_with_continue.rs: Lines 442-476 (SSOT extraction + validation) - pattern6_scan_with_init.rs: Lines 447-471 (SSOT extraction + validation) - pattern7_split_scan.rs: Lines 495-526 (SSOT extraction + validation) All patterns now use the same SSOT principle: 1. Extract entry function (priority: join_module.entry → fallback "main") 2. Use params as SSOT: join_inputs = entry_func.params.clone() 3. Build host_inputs in expected order (pattern-specific) 4. Fail-fast validation: join_inputs.len() == host_inputs.len() Verification: - cargo build --release: ✅ PASS (no PARAM_MIN warnings) - Quick profile: ✅ First FAIL still json_lint_vm (baseline maintained) - Pattern6 smoke: ✅ PASS (index_of test) - Pattern7 smoke: Pre-existing phi pred mismatch (not introduced by SSOT) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

### 設計方針メモ（SSOT候補）
- ExprLowererBox（式SSOT）
- 役割: `AST(expr)` → `(prelude: Vec<Inst>, value: ValueId)`（ANF含む）
- pure/impure/whitelist/strict の契約を集約（入口SSOT）
- ConditionLowererBox（条件→分岐SSOT）
- 役割: `AST(cond)` → `BranchPlan`（短絡なら分岐語彙で組む）
- 評価順は ExprLowererBox に委譲（ANFで順序固定）
- `&&/||` は制御として扱い、式で無理しない
- ControlLowererBox（制御SSOT）
- 役割: `StepNode/ControlTree` → JoinIR（継続 + env）
- `if/loop` はここ、条件の中身は ConditionLowererBox に委譲

## Resolved (historical)
### WSL EXDEV / cargo build failure (resolved)
- 2025-12-18: `Invalid cross-device link (os error 18)` により `cargo build` が失敗する事象があったが、`wsl --shutdown` 再起動後に復旧。
- 再発時のワークアラウンド: `tools/build_llvm.sh` は EXDEV を避けるため `TMPDIR` を `target/...` 配下へ寄せる。
