- ChromaDB → Qdrant 전환 (맥미니 기존 인스턴스, tk_qc_issues 컬렉션) - Ollama 임베딩/텍스트 생성 URL 분리 (임베딩: 맥미니, 텍스트: GPU서버) - MLX fallback 제거, Ollama 단일 경로로 단순화 - ds923 docker-compose에서 ai-service 제거 - gateway/system3-web nginx: ai-service 프록시를 ai.hyungi.net 경유로 변경 - resolver + 변수 기반 proxy_pass로 런타임 DNS 해석 (컨테이너 시작 실패 방지) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
