Phase 161 Task 1 completion: Complete documentation of MIR JSON v1 and JoinIR JSON schemas with:
- Full schema definitions for all 14 MIR instruction types
- PHI/Loop/If identification methods and criteria
- Type hint propagation algorithms
- 3 representative JSON snippets (if_select_simple, min_loop, skip_ws)
- 5-stage implementation checklist for .hako Analyzer
Recommendation: Prioritize MIR JSON v1 over JoinIR for initial .hako Analyzer implementation
due to unified Call instruction support and CFG integration (Phase 155).
docs(phase173b): Add comprehensive StaticBoxRegistry boxification assessment
Confirms Phase 173-B reached optimal complexity:
- All 3 fields (declarations, detected_boxes, instances) are necessary
- All public methods (exists, get_or_create_instance, register_declaration) serve distinct purposes
- Design principles properly applied (箱化、境界作成、Fail-Fast、遅延シングルトン)
- No further simplification possible without losing correctness
- Ready for Phase 34+ work
