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) - Update analysis_consumer.hako to call bridge - Activate HC020 end-to-end testing 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
