76e723cdb1 feat(search): Phase 1.3 TEI reranker 통합 (코드 골격)
데이터 흐름 원칙: fusion=doc 기준 / reranker=chunk 기준 — 절대 섞지 말 것.

신규/수정:
- ai/client.py: rerank() 메서드 추가 (TEI POST /rerank API)
- services/search/rerank_service.py:
    - rerank_chunks() — asyncio.Semaphore(2) + 5s soft timeout + RRF fallback
    - _make_snippet/_extract_window — title + query 중심 200~400 토큰
      (keyword 매치 없으면 첫 800자 fallback)
    - apply_diversity() — max_per_doc=2, top score>=0.90 unlimited
    - warmup_reranker() — 10회 retry + 3초 간격 (TEI 모델 로딩 대기)
    - MAX_RERANK_INPUT=200, MAX_CHUNKS_PER_DOC=2 hard cap
- services/search_telemetry.py: compute_confidence_reranked() — sigmoid score 임계값
- api/search.py:
    - ?rerank=true|false 파라미터 (기본 true, hybrid 모드만)
    - 흐름: fused_docs(limit*5) → chunks_by_doc 회수 → rerank_chunks → apply_diversity
    - text-only 매치 doc은 doc 자체를 chunk처럼 wrap (fallback)
    - rerank 활성 시 confidence는 reranker score 기반
- tests/search_eval/run_eval.py: --rerank true|false 플래그

GPU 적용 보류:
- TEI 컨테이너 추가 (docker-compose.yml) — 별도 작업
- config.yaml rerank.endpoint 갱신 — GPU 직접 (commit 없음)
- 재인덱싱 완료 후 build + warmup + 평가셋 측정

47e9981660 fix: Qwen3.5 Thinking Process 텍스트 제거 — JSON 파싱 개선
첫 번째 { 이전의 모든 비-JSON 텍스트를 제거하여
thinking/reasoning preamble이 있어도 JSON 추출 가능.

d93e50b55c security: fix 5 review findings (2 high, 3 medium)
HIGH:
- Lock setup TOTP/NAS endpoints behind _require_setup() guard
  (prevented unauthenticated admin 2FA takeover after setup)
- Sanitize upload filename with Path().name + resolve() validation
  (prevented path traversal writing outside Inbox)

MEDIUM:
- Add score > 0.01 filter to hybrid search via subquery
  (prevented returning irrelevant documents with zero score)
- Implement Inbox → Knowledge file move after classification
  (classify_worker now moves files based on ai_domain)
- Add Anthropic Messages API support in _request()
  (premium/Claude path now sends correct format and parses
  content[0].text instead of choices[0].message.content)

299fac3904 feat: implement Phase 1 data pipeline and migration
- Implement kordoc /parse endpoint (HWP/HWPX/PDF via kordoc lib,
  text files direct read, images flagged for OCR)
- Add queue consumer with APScheduler (1min interval, stage chaining
  extract→classify→embed, stale item recovery, retry logic)
- Add extract worker (kordoc HTTP call + direct text read)
- Add classify worker (Qwen3.5 AI classification with think-tag
  stripping and robust JSON extraction from AI responses)
- Add embed worker (GPU server nomic-embed-text, graceful failure)
- Add DEVONthink migration script with folder mapping for 16 DBs,
  dry-run mode, batch commits, and idempotent file_path UNIQUE
- Enhance ai/client.py with strip_thinking() and parse_json_response()

131dbd7b7c feat: scaffold v2 project structure with Docker, FastAPI, and config
동작하는 최소 코드 수준의 v2 스캐폴딩:

- docker-compose.yml: postgres, fastapi, kordoc, frontend, caddy
- app/: FastAPI 백엔드 (main, core, models, ai, prompts)
- services/kordoc/: Node.js 문서 파싱 마이크로서비스
- gpu-server/: AI Gateway + GPU docker-compose
- frontend/: SvelteKit 기본 구조
- migrations/: PostgreSQL 초기 스키마 (documents, tasks, processing_queue)
- tests/: pytest conftest 기본 설정
- config.yaml, Caddyfile, credentials.env.example 갱신
