Phase 5.1 구현 완료: SubgraphRetriever + PatternMatcher
[SubgraphRetriever] - retrieve_neighborhood(entity_id, hops): N-hop 이웃 추출 - retrieve_context(entity_ids): 다중 엔티티 공통 경로 검색 - retrieve_induced_subgraph(entity_ids): 유도 부분 그래프 생성 - Cypher 최적화로 2-hop 쿼리 < 200ms [PatternMatcher] - find_paths(start, end, max_length): 경로 탐색 (깊이 우선) - find_cycles(min_length): 순환 의존성 감지 - find_strongly_connected_components(): SCC 분석 - find_motifs(type): 삼각형/체인/별 모티프 검출 - analyze_entity_connectivity(entity_id): 연결 메트릭 [테스트] - test_phase5_subgraph_retriever.py (6 테스트 통과) - test_phase5_pattern_matcher.py (10 테스트 통과) - test_phase5_integration_graphrag.py (6 통합 테스트 통과) Phase 5.2 (Graph Analytics) 준비 완료 Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
