R4-R7: 全モジュール深層カバレッジ補完（727テスト/0FAIL）
R4: core.py(289IF) + __init__.py(91IF) 内部関数全網羅
R4-design: design.py(161IF) enum_paths/constraint/redefines/occurs
R4-cond: cond.py(51IF) 全演算子×T/F×MC/DC
R4-coverage: coverage.py(116IF) mark_*全種別+HTML分岐
R5: 統合テスト(extract_structure→generate_data検証)
+ pipeline.py(34IF)+hina_agent.py(12IF)+read.py(54IF)
+ output.py(19IF)+orchestrator.py+classifier.py追加
R6: 複合ネストIF/PERFORM/EVAL/SEARCH+PIC解析全部
R7: FD方向解析+混乱グループ+contradiction+LLM応答
残環境依存: web/api(6IF), web/worker(6IF), runners/(6IF), gcov(6IF)
