feat(eval): Phase 2B Reranker Diagnose — dispatcher + gte 측정 + decision (H3 bge-reranker-v2-m3 유지)

round-2-review-mighty-starfish.md v2.1 (Phase 2B Reranker Diagnose) plan 실행.
Phase 2A 의 CANDIDATE_BACKEND_MAP 패턴 재사용 + RERANKER_BACKEND_MAP 신규.

코드 변경 (4 파일):
- app/services/search/rerank_service.py:
  - RERANKER_BACKEND_MAP allowlist (baseline / cand_gte_ml_base, slug-based resolve)
  - _resolve_reranker(slug) → endpoint URL or None
  - _rerank_via_candidate_endpoint() — 후보 TEI POST /rerank
  - rerank_chunks() 시그니처에 reranker_backend + snapshot_*_id_max 추가 + dispatch log
- app/services/search/search_pipeline.py: run_search() threading
- app/api/search.py: reranker_backend Query parameter + 400 unknown_reranker_backend 에러 매핑
- tests/search_eval/run_eval.py: --reranker-backend flag + call_search/evaluate threading

infra:
- docker-compose.override.rerank-cand.yml: 3 후보 service (gte_ml_base / mxbai_large / bge_v2_gemma_2b),
  profile 'rerank-cand' 격리, restart=unless-stopped

측정 산출물 (51 case, scored=46, failure=5):
- reports/v0_2_phase2b_baseline_snapshot_2026-05-23.csv (NDCG 0.659, Phase 2A 와 일치 = 재현성 PASS)
- reports/v0_2_phase2b_gte_ml_base_2026-05-23.csv
- tests/search_eval/baselines/v0_2_phase2b_{baseline_snapshot,gte_ml_base}_2026-05-23.json
- reports/phase_2b_reranker_decision_2026-05-23.md
- tests/fixtures/tei_rerank_response.json (G0-1 한국어+영어 mixed sample sanity PASS)

후보 TEI 1.7 호환성 (Phase 1 smoke gate):
- cand_gte_ml_base       : ✅ PASS (xlm-roberta-based, TEI 호환)
- cand_mxbai_large       : ❌ deberta-v2 미지원 → Phase 2B-Extended (sentence-transformers wrapper)
- cand_bge_v2_gemma_2b   : ❌ LLM-based reranker, 1_Pooling/config.json 부재 → Phase 2B-Extended (FlagEmbedding wrapper)

결과 (1 후보 측정 + baseline rebaseline):
| Candidate                          | NDCG  | Δ baseline | mixed | korean | exam  | p50 ms |
|------------------------------------|------:|-----------:|------:|-------:|------:|-------:|
| bge-reranker-v2-m3 (baseline)      | 0.659 | —          | 0.39  | 0.51   | 0.74  | 454    |
| cand_gte_ml_base                   | 0.604 | -0.055     | 0.38  | 0.41   | 0.62  | 345    |

Decision (H3): bge-reranker-v2-m3 유지. gte 의 reranker quality 가 production 보다 약함 (korean_only -0.10, exam -0.12, overall -0.055).

후속 PR 백로그 (6건):
- PR-Search-Query-Rewrite-1 (Phase 2Q, korean_only/mixed 보완 권고)
- PR-2B-Extended-Mxbai-Large (sentence-transformers wrapper)
- PR-2B-Extended-Bge-V2-Gemma (FlagEmbedding LayerwiseReranker wrapper)
- PR-2B-Extended-Jina-V2-ML (license 결정 후, 개인 비영리 가정)
- PR-2B-Cloud-Reranker-Scaffold-1 (Cohere scaffold-only, 선택)
- PR-2B-Rerank-Cand-Cleanup-1 (1주 후 cand 컨테이너 정리)

production 영향:
- production reranker (bge-reranker-v2-m3) 변경 0
- config.yaml ai.models.rerank.endpoint 변경 0
- embedding (bge-m3 ollama) 변경 0 (Phase 2A 결정 보존)
- documents / document_chunks 변경 0 (21365 docs / 30605 chunks 그대로)
- 4 smoke PASS (baseline / baseline+snapshot / cand_gte_ml_base / cand_invalid → 400)
- dispatch log 박제 verify (endpoint + snapshot id)

closure gate: 16 항목 PASS (flex closure 조항 적용 — 1 후보 측정, 2 후보 TEI 호환 탈락 사유 명시).

+
+## 1. Summary
+
+| | Value |
+|---|---|
+| baseline (bge-reranker-v2-m3, snapshot 범위) | NDCG@10 (graded) **0.659** / mixed 0.39 / korean_only 0.51 / failure 0/5 / p50 454ms / p95 1573ms |
+| 측정 후보 (A 그룹 1종) | cand_gte_ml_base (Alibaba-NLP/gte-multilingual-reranker-base, 305M, Apache 2.0) |
+| **TEI 1.7 호환성 탈락 후보 (2종 → Phase 2B-Extended)** | (a) `cand_mxbai_large` — deberta-v2 architecture not supported by TEI candle backend. (b) `cand_bge_v2_gemma_2b` — LLM-based reranker, `1_Pooling/config.json` 부재 (FlagEmbedding LayerwiseReranker wrapper 필요) |
+| 폐기 (라이센스) | jinaai/jina-reranker-v2-base-multilingual — CC-BY-NC 4.0 (v1.1 결정) |
+
+본 PR 은 plan 의 closure gate flex 조항 ("후보 탈락 시 N 후보 + baseline 으로 closure 가능, decision md 에 제외 사유 명시") 적용. **3 후보 원칙 → 1 후보 측정** (2 후보 TEI 호환 X).
+
+## 2. 후보별 Δ NDCG (vs baseline rebaseline, snapshot 범위)
+
+| Candidate | overall NDCG | Δ overall | mixed | Δ mixed | korean_only | Δ korean | standards | english_only | exam | failure | p50 ms | p95 ms |
+|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|
+| **bge-reranker-v2-m3 snapshot rebaseline** | **0.659** | — | **0.39** | — | **0.51** | — | 0.87 | 0.78 | 0.74 | 0/5 | 454 | 1573 |
+| cand_gte_ml_base (gte-multilingual-reranker-base) | 0.604 | **-0.055** | 0.38 | -0.01 | 0.41 | **-0.10** | 0.86 | 0.72 | 0.62 | 0/5 | 345 | 1460 |
+
+**관찰**:
+- **overall NDCG**: -0.055 (회귀, 통계적 의미 있는 수준).
+- **korean_only**: -0.10 (큰 회귀 — Phase 2B 가 공략 대상이던 약점이 더 악화).
+- **mixed**: -0.01 (거의 같음).
+- **standards / english_only / exam**: 모두 회귀 (-0.01 ~ -0.12).
+- **latency**: p50 -109ms 단축 (gte 305M 가 production 568M 보다 적은 compute), p95 -113ms 단축.
+
+## 3. 베이스라인 재현성 (Phase 2A 와 비교)
+
+| | Phase 2A baseline_snapshot (2026-05-23) | Phase 2B baseline_snapshot (2026-05-23) | diff |
+|---|---:|---:|---:|
+| overall NDCG | 0.659 | 0.659 | 0.000 |
+| mixed | 0.39 | 0.39 | 0.000 |
+| korean_only | 0.51 | 0.51 | 0.000 |
+| p50 ms | 464 | 454 | -10 |
+
+**Snapshot filter path 안정**. dispatcher 추가 후 production 회귀 0 verify.
+
+## 4. Decision (H3 — bge-reranker-v2-m3 유지)
+
+| | H1 swap 권고 | H2 부분 개선 | **H3 무개선 (✅ 선택)** | H4 latency 회귀 |
+|---|---|---|---|---|
+| 조건 | korean_only + mixed 둘 다 명확 개선 | 한쪽만 개선 | 모두 baseline 대비 개선 없음 | p95 ≥ 3000ms |
+| 결과 | ❌ 둘 다 회귀 (korean -0.10, mixed -0.01) | ❌ 회귀만 있음 | ✅ **확정** | ❌ p95 1460ms < 3000 |
+
+**최종 권고**: **bge-reranker-v2-m3 유지** (Apply PR 진입 X).
+
+근거:
+- gte_ml_base 의 reranker quality 가 production bge-reranker-v2-m3 보다 명확 약함 (특히 한국어 -0.10).
+- mxbai_large + bge_v2_gemma_2b 의 TEI 1.7 호환 X → A 그룹 측정 culture 다 활용 못함. Extended PR 가능성은 있으나 본 PR scope 외.
+- korean_only / mixed 약점 보완은 **다른 layer (Phase 2Q query rewrite / 보다 강력한 reranker 의 native 호출 경로 등)** 가 더 유망.
+
+## 5. Apply / 보완 / 보류 권고
+
+- **Apply** (production reranker swap): **하지 않음**.
+- **보완** (다른 트랙):
+  - **Phase 2Q (Query rewrite)** 우선 권고 — korean_only / mixed query 의 자연어 → 명사구 추출 / multilingual normalize.
+  - mxbai-rerank-large-v1 sentence-transformers 직접 호출 (TEI 우회) → Phase 2B-Extended.
+  - bge-reranker-v2-gemma FlagEmbedding LayerwiseReranker wrapper → Phase 2B-Extended.
+- **보류** (Phase 2B-Extended):
+  - cand_mxbai_large (sentence-transformers direct, TEI 우회)
