Merge pull request 'fix: parent_resolution JOIN 타이밍 갭 허용' (#226) from hotfix/join-timing-tolerance into main

5분 사이클에서 폴리곤 저장 → inference 실행 순서로 인해
latest snapshot_time > last_evaluated_at이 될 수 있음.
JOIN 조건에 10분 여유를 두어 이전 사이클 결과도 매칭되도록 수정.

+# Gear Parent Inference Algorithm Spec
+
+## 문서 목적
+
+이 문서는 현재 구현된 어구 모선 추적 알고리즘을 모듈, 메서드, 파라미터, 판단 기준, 저장소, 엔드포인트, 영향 관계 기준으로 정리한 구현 명세다. `GEAR-PARENT-INFERENCE-DATAFLOW-PAPER.md`가 서술형 통합 문서라면, 이 문서는 구현과 후속 변경 작업에 바로 연결할 수 있는 참조 스펙이다.
+
+## 1. 시스템 요약
+
+### 1.1 현재 목적
+
+- 최근 24시간 한국 수역 AIS를 캐시에 유지한다.
+- 어구 이름 패턴과 위치를 기준으로 어구 그룹을 만든다.
+- 주변 선박/오분류 어구를 correlation 후보로 평가한다.
+- 후보 중 대표 모선 가능성이 높은 선박을 추론한다.
+- 사람의 라벨/제외를 별도 저장소에 남겨 향후 모델 평가와 자동화 전환에 활용한다.
+
+### 1.2 현재 점수 구조의 역할 구분
+
+- `gear_correlation_scores.current_score`
+  - 후보 스크리닝용 correlation score
+  - EMA 기반 단기 메모리
+- `gear_group_parent_candidate_snapshots.final_score`
+  - 모선 추론용 최종 후보 점수
+  - coverage-aware 보정과 이름/안정성/episode/lineage/label prior 반영
+- `gear_group_parent_resolution`
+  - 그룹별 현재 추론 상태
+- `gear_group_episodes`, `gear_group_episode_snapshots`
+  - `sub_cluster_id`와 분리된 continuity memory
+- `gear_parent_label_tracking_cycles`
+  - 라벨 세션 동안의 자동 추론 성능 추적
+
+## 2. 현재 DB 저장소와 유지 기간
+
+| 저장소 | 역할 | 현재 유지 규칙 |
+| --- | --- | --- |
+| `group_polygon_snapshots` | `1h/1h-fb/6h` 그룹 스냅샷 | `7일` cleanup |
+| `gear_correlation_raw_metrics` | correlation raw metric 시계열 | `7일` retention partition |
+| `gear_correlation_scores` | correlation EMA score 현재 상태 | `30일` 미관측 시 cleanup |
+| `gear_group_parent_candidate_snapshots` | cycle별 parent candidate snapshot | 현재 자동 cleanup 없음 |
+| `gear_group_parent_resolution` | 그룹별 현재 추론 상태 1행 | 현재 자동 cleanup 없음 |
+| `gear_group_episodes` | active/merged/expired episode 현재 상태 | 현재 자동 cleanup 없음 |
+| `gear_group_episode_snapshots` | cycle별 episode continuity 스냅샷 | 현재 자동 cleanup 없음 |
+| `gear_parent_candidate_exclusions` | 그룹/전역 후보 제외 | 기간 종료 또는 수동 해제까지 |
+| `gear_parent_label_sessions` | 정답 라벨 세션 | 만료 시 `EXPIRED`, row는 유지 |

+- 조건:
+  - stale resolution 숨김

+
+- 역할:
+  - 특정 그룹의 현재 live sub-cluster 상세
+- 주의:
+  - “현재 최신 전역 `1h`에 실제 존재하는 sub-cluster만” 반환
+
+### `/api/kcg/vessel-analysis/parent-inference/candidate-exclusions`

+  - 그룹/전역 제외 목록 조회
+
+### `/api/kcg/vessel-analysis/parent-inference/label-sessions`

+- 역할:

+
+## 6. 현재 기억 구조와 prior bonus
+
+### 6.1 short-memory와 long-memory의 분리
+
+- `gear_correlation_scores`
+  - EMA short-memory
+  - 미관측 시 decay
+  - 현재 후보 seed 역할
+- `gear_group_parent_resolution`
+  - 현재 상태 1행
+  - same-episode가 아니면 `PREVIOUS_SELECTION` carry를 직접 사용하지 않음
+- `gear_group_episodes`
+  - continuity memory
+- `candidate_snapshots`
+  - bonus 집계 원천
+
+### 6.2 현재 final score의 장기 기억 반영
+
+현재는 과거 점수를 직접 carry하지 않고, 약한 prior bonus만 후가산한다.
+
+```text
+final_score =
+  current_signal_score
+  + china_mmsi_bonus
+  + prior_bonus_total
+```
+
+여기서 `prior_bonus_total`은:
+
+- `episode_prior_bonus`
+- `lineage_prior_bonus`
+- `label_prior_bonus`
+
+의 합이며 총합 cap은 `0.20`이다.
+
+### 6.3 왜 weak prior인가
+
+과거 점수를 그대로 넘기면:
+
+- 다른 episode로 잘못 관성이 전이될 수 있다
+- split/merge 이후 잘못된 top1이 고착될 수 있다
+- 오래된 오답이 장기 drift로 남을 수 있다
+
+그래서 현재 구현은 과거 점수를 “현재 score 자체”가 아니라 “작은 bonus”로만 쓴다.
+
+## 7. 현재 continuity / prior 동작
+
+### 7.1 episode continuity
+
+- 같은 lineage 안에서 최근 `6h` active episode를 불러온다.
+- continuity score가 높은 이전 episode가 있으면 `CONTINUED`
+- 1개 parent episode가 여러 current cluster로 이어지면 `SPLIT_CONTINUE` + `SPLIT_NEW`
+- 여러 previous episode가 하나 current cluster로 모이면 `MERGE_NEW`
+- 어떤 current와도 연결되지 못한 old episode는 `EXPIRED`
+
+### 7.2 prior 집계
+
+| prior | 참조 범위 | 현재 집계 값 |
+| --- | --- | --- |
+| episode prior | 최근 동일 episode `24h` | seen_count, top1_count, avg_score, last_seen_at |
+| lineage prior | 동일 이름 lineage `7d` | seen_count, top1_count, top3_count, avg_score, last_seen_at |
+| label prior | 라벨 세션 `30d` | session_count, last_labeled_at |
+
+### 7.3 구현 시 주의
+
+- 과거 점수를 직접 누적하지 말 것
+- prior는 bonus로만 사용하고 cap을 둘 것
+- split/merge 이후 parent 후보 관성은 약하게만 상속할 것
+- stale live sub-cluster와 vanished old sub-cluster를 혼동하지 않도록, aggregation도 최신 episode anchor를 기준으로 할 것

+# Gear Parent Inference Dataflow Paper
+
+## 초록
+
+이 문서는 `iran-airstrike-replay-codex`의 한국 수역 어구 모선 추적 체계를 코드 기준으로 복원하는 통합 기술 문서다. 범위는 `snpdb` 5분 궤적 적재, 인메모리 캐시 유지, 어구 그룹 검출, 서브클러스터 생성, `1h/1h-fb/6h` 폴리곤 스냅샷 저장, correlation 기반 후보 점수화, coverage-aware parent inference, `episode_id` 기반 연속성 계층, backend read model, review/exclusion/label v2까지 포함한다. 문서의 목적은 “현재 무엇이 구현되어 있고, 각 경우의 수에서 어떤 분기 규칙이 적용되는가”를 한 문서에서 복원 가능하게 만드는 것이다.
+
+## 1. 범위와 전제
+
+### 1.1 구현 기준
+
+- frontend: `frontend/`
+- backend: `backend/`
+- prediction: `prediction/`
+- schema migration: `database/migration/012_gear_parent_inference.sql`, `database/migration/014_gear_parent_workflow_v2_phase1.sql`, `database/migration/015_gear_parent_episode_tracking.sql`
+
+### 1.2 실행 환경
+
+- lab backend: `rocky-211:18083`
+- lab prediction: `redis-211:18091`
+- lab schema: `kcg_lab`
+- 로컬 프론트 진입점: `yarn dev:lab`, `yarn dev:lab:ssh`
+
+### 1.3 문서의 구분
+
+- 구현됨:
+  - 현재 repo 코드와 lab 배포에 이미 반영된 규칙
+- 후속 확장 후보:
+  - episode continuity 위에서 추가로 올릴 `focus mode`, richer episode lineage API, calibration report
+
+## 2. 문제 정의
+
+이 시스템은 한국 수역에서 AIS 신호를 이용해 아래 문제를 단계적으로 푼다.
+
+1. 최근 24시간의 선박/어구 궤적을 메모리 캐시에 유지한다.
+2. 동일한 어구 이름 계열을 공간적으로 묶어 어구 그룹을 만든다.
+3. 각 그룹에 대해 `1h`, `1h-fb`, `6h` 스냅샷을 생성한다.
+4. 주변 선박 또는 잘못 분류된 어구 AIS를 후보로 수집하고 correlation 점수를 만든다.
+5. 후보를 모선 추론 점수로 다시 환산한다.
+6. 사람이 라벨/제외를 누적해 모델 정확도 고도화용 데이터셋을 만든다.
+
+핵심 난점은 아래 세 가지다.
+
+- DB 적재 지연 때문에 live incremental cache와 fresh reload가 다를 수 있다.
+- 같은 `parent_name` 아래에서도 실제로는 여러 공간 덩어리로 갈라질 수 있다.
+- 짧은 항적이 `track/proximity/activity`에서 과대평가될 수 있다.

+
+## 4. 원천 데이터와 시간 모델
+
+### 4.1 원천 데이터 형식
+
+원천은 `signal.t_vessel_tracks_5min`이며, `1 row = 1 MMSI = 5분 구간의 궤적 전체`를 `LineStringM`으로 보관한다. 실제 위치 포인트는 `ST_DumpPoints(track_geom)`로 분해하고, 각 점의 timestamp는 `ST_M((dp).geom)`에서 꺼낸다. 구현 위치는 `prediction/db/snpdb.py`다.
+
+### 4.2 safe watermark
+
+현재 구현은 “DB 적재가 완료된 bucket만 읽는다”는 원칙을 따른다.
+
+- `prediction/time_bucket.py`
+  - `compute_safe_bucket()`
+  - `compute_initial_window_start()`
+  - `compute_incremental_window_start()`
+- 기본값:
+  - `SNPDB_SAFE_DELAY_MIN`
+  - `SNPDB_BACKFILL_BUCKETS`
+
+핵심 규칙:
+
+1. 초기 적재는 `now - safe_delay`를 5분 내림한 `safe_bucket`까지만 읽는다.
+2. 증분 적재는 `last_bucket - backfill_window`부터 `safe_bucket`까지 다시 읽는다.
+3. live cache는 `timestamp`가 아니라 `time_bucket` 기준으로 24시간 cutoff를 맞춘다.
+
+### 4.3 왜 safe watermark가 필요한가
+
+`time_bucket > last_bucket`만 사용하면, 늦게 들어온 같은 bucket row를 영구히 놓칠 수 있다. 현재 구현은 overlap backfill과 dedupe로 이 drift를 줄인다.
+
+- 조회: `prediction/db/snpdb.py`
+- 병합 dedupe: `prediction/cache/vessel_store.py`
+
+## 5. Stage 1: 캐시 적재와 유지
+
+### 5.1 초기 적재
+
+`prediction/main.py`는 시작 시 `vessel_store.load_initial(24)`를 호출한다.
+
+`prediction/cache/vessel_store.py`의 규칙:
+
+1. `snpdb.fetch_all_tracks(hours)`로 최근 24시간을 safe bucket까지 읽는다.
+2. MMSI별 DataFrame으로 `_tracks`를 구성한다.
+3. 최대 `time_bucket`을 `_last_bucket`으로 저장한다.
+4. static info와 permit registry를 함께 refresh한다.
+
+### 5.2 증분 병합
+
+스케줄러는 `snpdb.fetch_incremental(vessel_store.last_bucket)`로 overlap backfill 구간을 다시 읽는다.
+
+`merge_incremental()` 규칙:
+
+1. 기존 DataFrame과 새 batch를 합친다.
+2. `timestamp`, `time_bucket`으로 정렬한다.
+3. `timestamp` 기준 중복은 `keep='last'`로 제거한다.
+4. batch의 최대 `time_bucket`이 더 크면 `_last_bucket`을 갱신한다.
+
+### 5.3 stale eviction
+
+`evict_stale()`는 safe bucket 기준 24시간 이전 포인트를 제거한다. `time_bucket`이 있으면 bucket 기준, 없으면 timestamp 기준으로 fallback한다.
+
+## 6. Stage 2: 어구 identity 추출
+
+`prediction/fleet_tracker.py`는 어구 이름 패턴에서 `parent_name`, `gear_index_1`, `gear_index_2`를 파싱하고 `gear_identity_log`를 관리한다.
+
+### 6.1 이름 기반 필터
+
+공통 규칙은 `prediction/algorithms/gear_name_rules.py`에 있다.
+
+- 정규화:
+  - 대문자화
+  - 공백, `_`, `-`, `%` 제거
+- 추적 가능 최소 길이:
+  - 정규화 길이 `>= 4`
+
+`fleet_tracker.py`와 `polygon_builder.py`는 모두 `is_trackable_parent_name()`을 사용한다. 즉 짧은 이름은 추론 이전, 그룹 생성 이전 단계부터 제외된다.
+
+### 6.2 identity log 동작
+
+`fleet_tracker.py`의 핵심 분기:
+
+1. 같은 MMSI + 같은 이름:
+  - 기존 활성 row의 `last_seen_at`, 위치만 갱신
+2. 같은 MMSI + 다른 이름:
+  - 기존 row 비활성화
+  - 새 row insert
+3. 다른 MMSI + 같은 이름:
+  - 기존 row 비활성화
+  - 새 MMSI로 row insert
+  - 기존 `gear_correlation_scores.target_mmsi`를 새 MMSI로 이전
+
+## 7. Stage 3: 어구 그룹 생성과 서브클러스터
+
+실제 어구 그룹은 `prediction/algorithms/polygon_builder.py`의 `detect_gear_groups()`가 만든다.
+
+### 7.1 1차 그룹화
+
+규칙:
+
+1. 최신 position 이름이 어구 패턴에 맞아야 한다.
+2. `STALE_SEC`를 넘는 오래된 신호는 제외한다.
+3. `440`, `441` MMSI는 어구 AIS 미사용으로 간주해 제외한다.
+4. `is_trackable_parent_name(parent_raw)`를 만족해야 한다.
+5. 같은 `parent_name`은 공백 제거 버전으로 묶는다.
+
+### 7.2 서브클러스터 생성
+
+같은 이름 아래에서도 거리 기반 연결성으로 덩어리를 나눈다.
+
+- 거리 임계치: `MAX_DIST_DEG = 0.15`
+- 연결 규칙:
+  - 각 어구가 클러스터 내 최소 1개와 `MAX_DIST_DEG` 이내면 같은 연결 요소
+- 구현:
+  - Union-Find
+
+모선이 이미 있으면, 모선과 가장 가까운 클러스터를 seed cluster로 간주한다.
+
+### 7.3 `sub_cluster_id` 부여 규칙
+
+현재 구현은 아래와 같다.
+
+1. 클러스터가 1개면 `sub_cluster_id = 0`
+2. 클러스터가 여러 개면 `1..N`
+3. 이후 동일 `parent_key`의 두 서브그룹이 다시 근접 병합되면 `sub_cluster_id = 0`
+
+즉 `sub_cluster_id`는 영구 식별자가 아니라 “그 시점의 공간 분리 라벨”이다.
+
+### 7.4 병합 규칙
+
+동일 `parent_key`의 두 그룹이 다시 가까워지면:
+
+1. 멤버를 합친다.
+2. 부모 MMSI가 없는 큰 그룹에 작은 그룹의 `parent_mmsi`를 승계할 수 있다.
+3. `sub_cluster_id = 0`으로 재설정한다.
+
+### 7.5 스냅샷 생성 규칙
+
+`build_all_group_snapshots()`는 각 그룹에 대해 `1h`, `1h-fb`, `6h` 스냅샷을 만든다.
+
+- `1h`
+  - 같은 `parent_name` 전체 기준 1시간 활성 멤버 수 `>= 2`
+- `1h-fb`
+  - 같은 `parent_name` 전체 기준 1시간 활성 멤버 수 `< 2`
+  - 리플레이/일치율 추적용
+  - 라이브 현황에서 제외
+- `6h`
+  - 6시간 내 stale이 아니어야 함
+
+추가 규칙:
+
+1. 서브클러스터 내 1h 활성 멤버가 2개 미만이면 최신 2개로 fallback display를 만든다.
+2. 수역 외(`GEAR_OUT_ZONE`)인데 멤버 수가 `MIN_GEAR_GROUP_SIZE` 미만이면 스킵한다.
+3. 모선이 있고, 멤버와 충분히 근접하면 `members[].isParent = true`로 같이 넣는다.
+
+## 8. Stage 4: correlation 모델
+
+`prediction/algorithms/gear_correlation.py`는 어구 그룹별 raw metric과 EMA score를 만든다.
+
+### 8.1 후보 생성
+
+입력:
+
+- group center
+- group radius
+- active ratio
+- group member MMSI set
+
+출력 후보:
+
+- 선박 후보(`VESSEL`)
+- 잘못 분류된 어구 후보(`GEAR_BUOY`)
+
+후보 수는 그룹당 최대 `30`개로 제한된다.
+
+### 8.2 raw metric
+
+선박 후보는 최근 6시간 항적 기반으로 아래 값을 만든다.
+
+- `proximity_ratio`
+- `visit_score`
+- `activity_sync`
+- `dtw_similarity`
+
+어구 후보는 단순 거리 기반 `proximity_ratio`만 사용한다.
+
+### 8.3 EMA score
+
+모델 파라미터(`gear_correlation_param_models`)별로 아래를 수행한다.
+
+1. composite score 계산
+2. 이전 score와 streak를 읽는다
+3. `update_score()`로 EMA 갱신
+4. threshold 이상이거나 기존 row가 있으면 upsert
+
+반대로 이번 사이클 후보군에서 빠진 기존 항목은 `OUT_OF_RANGE`로 fast decay된다.
+
+### 8.4 correlation 산출물
+
+- `gear_correlation_raw_metrics`
+- `gear_correlation_scores`
+
+여기까지는 “잠재적 모선/근접 대상”의 score이고, 최종 parent inference는 아직 아니다.
+
+## 9. Stage 5: parent inference
+
+`prediction/algorithms/gear_parent_inference.py`가 최종 모선 추론을 수행한다.
+
+전체 진입점은 `run_gear_parent_inference(vessel_store, gear_groups, conn)`이다.
+
+### 9.1 전체 분기 개요
+
+```mermaid
+flowchart TD
+    A["active gear group"] --> B{"direct parent member<br/>exists?"}
+    B -- yes --> C["DIRECT_PARENT_MATCH<br/>fresh resolution upsert"]

+    L -- yes --> M["REVIEW_REQUIRED"]
+    L -- no --> N["UNRESOLVED"]
+```
+
+### 9.1.1 episode continuity 선행 단계
+
+현재 구현에서 `run_gear_parent_inference()`는 후보 점수를 만들기 전에 먼저 `prediction/algorithms/gear_parent_episode.py`를 호출해 active 그룹의 continuity를 계산한다.
+
+입력:
+
+- 현재 cycle `gear_groups`
+- 정규화된 `parent_name`
+- 최근 `6h` active `gear_group_episodes`
+- 최근 `24h` episode prior, `7d` lineage prior, `30d` label prior 집계
+
+핵심 규칙:
+
+1. continuity score는 `0.75 * member_jaccard + 0.25 * center_support`다.
+2. 중심점 지원값은 `12nm` 이내일수록 커진다.
+3. continuity score가 충분하거나, overlap member가 있고 거리 조건을 만족하면 연결 후보로 본다.
+4. 두 개 이상 active episode가 하나의 현재 cluster로 들어오면 `MERGE_NEW`다.
+5. 하나의 episode가 여러 현재 cluster로 갈라지면 하나는 `SPLIT_CONTINUE`, 나머지는 `SPLIT_NEW`다.
+6. 아무 previous episode와도 연결되지 않으면 `NEW`다.
+7. 현재 cycle과 연결되지 못한 active episode는 `EXPIRED` 또는 `MERGED`로 종료한다.
+
+현재 저장되는 continuity 메타데이터:
+
+- `gear_group_parent_candidate_snapshots.episode_id`
+- `gear_group_parent_resolution.episode_id`
+- `gear_group_parent_resolution.continuity_source`
+- `gear_group_parent_resolution.continuity_score`
+- `gear_group_parent_resolution.prior_bonus_total`
+- `gear_group_episodes`
+- `gear_group_episode_snapshots`
+
+### 9.2 direct parent 보강
+
+최신 어구 그룹에 아래 중 하나가 있으면 후보 추론 대신 직접 모선 매칭으로 처리한다.
+
+1. `members[].isParent = true`
+2. `group.parent_mmsi` 존재
+
+이 경우:
+
+- `status = DIRECT_PARENT_MATCH`
+- `decision_source = DIRECT_PARENT_MATCH`
+- `confidence = 1.0`
+- `candidateCount = 0`
+
+단, 기존 상태가 `MANUAL_CONFIRMED`면 그 수동 상태를 유지한다.
+
+### 9.3 짧은 이름 스킵
+
+정규화 이름 길이 `< 4`면:
+
+- 후보 생성 자체를 수행하지 않는다.
+- `status = SKIPPED_SHORT_NAME`
+- `decision_source = AUTO_SKIP`
+
+### 9.4 후보 집합
+
+후보 집합은 아래의 합집합이다.
+
+1. default correlation model 상위 후보
+2. registry name exact bucket
+3. 기존 resolution의 `selected_parent_mmsi` 또는 이전 top candidate
+
+여기에 아래를 적용한다.
+
+- active global exclusion 제거
+- active group exclusion 제거
+- 최근 reject cooldown 후보 제거
+
+### 9.5 이름 점수
+
+현재 구현 규칙:
+
+1. 원문 완전일치: `1.0`
+2. 정규화 완전일치: `0.8`
+3. prefix/contains: `0.5`
+4. 숫자를 제거한 순수 문자 부분만 동일: `0.3`
+5. 그 외: `0.0`
+
+비교 대상:
+
+- `parent_name`
+- 후보 AIS 이름
+- registry `name_cn`
+- registry `name_en`
+
+### 9.6 coverage-aware evidence
+
+짧은 항적 과대평가를 막기 위해 raw score와 effective score를 분리한다.
+
+evidence에 남는 값:
+
+- `trackPointCount`
+- `trackSpanMinutes`
+- `overlapPointCount`
+- `overlapSpanMinutes`
+- `inZonePointCount`
+- `inZoneSpanMinutes`
+- `trackCoverageFactor`
+- `visitCoverageFactor`
+- `activityCoverageFactor`
+- `coverageFactor`
+
+현재 최종 점수에는 raw가 아니라 adjusted score가 들어간다.
+
+### 9.7 점수 식
+
+가중치 합은 아래다.
+
+- `0.40 * base_corr`
+- `0.15 * name_match`
+- `0.15 * track_similarity_effective`
+- `0.10 * visit_effective`
+- `0.05 * proximity_effective`
+- `0.05 * activity_effective`
+- `0.10 * stability`
+- `+ registry_bonus(0.05)`
+
+그 다음 별도 후가산:
+
+- `412/413` MMSI 보너스 `+0.15`
+- 단, `preBonusScore >= 0.30`일 때만 적용
+- `episode/lineage/label prior bonus`
+  - 최근 동일 episode `24h`
+  - 동일 lineage `7d`
+  - 라벨 세션 `30d`
+  - 총합 cap `0.20`
+
+### 9.8 상태 전이
+
+분기 조건:
+
+- `NO_CANDIDATE`
+  - 후보가 하나도 없을 때
+- `AUTO_PROMOTED`
+  - `target_type == VESSEL`
+  - candidate source에 `CORRELATION` 포함
+  - `final_score >= auto_promotion_threshold`
+  - `margin >= auto_promotion_margin`
+  - `stable_cycles >= auto_promotion_stable_cycles`
+- `REVIEW_REQUIRED`
+  - `final_score >= 0.60`
+- `UNRESOLVED`
+  - 나머지
+
+추가 예외:
+
+- 기존 상태가 `MANUAL_CONFIRMED`면 수동 상태를 유지한다.
+- active label session이 있으면 tracking row를 별도로 적재한다.
+
+### 9.9 산출물
+
+- `gear_group_parent_candidate_snapshots`
+- `gear_group_parent_resolution`
+- `gear_parent_label_tracking_cycles`
+- `gear_group_episodes`
+- `gear_group_episode_snapshots`
+
+## 10. Stage 6: backend read model
+
+backend의 중심은 `backend/.../GroupPolygonService.java`다.
+
+### 10.1 최신 1h만 라이브로 간주
+
+group list, review queue, detail API는 모두 최신 전역 `1h` 스냅샷만 기준으로 삼는다.
+
+핵심 효과:
+
+1. `1h-fb`는 라이브 현황에서 기본 제외된다.
+2. 이미 사라진 과거 sub-cluster는 detail API에서 다시 보이지 않는다.
+
+### 10.2 stale inference 차단
+
+`resolution.last_evaluated_at >= group.snapshot_time`인 경우만 join한다.
+
+즉 최신 group snapshot보다 오래된 candidate/resolution은 detail/review/list에서 숨긴다. 이 규칙이 `ZHEDAIYU02433`, `ZHEDAIYU02394` 유형 stale 표시를 막는다.
+
+### 10.3 detail API 의미
+
+`/api/kcg/vessel-analysis/groups/{groupKey}/parent-inference`
+
+현재 의미:
+
+- 해당 그룹의 최신 전역 `1h` live sub-cluster 집합
+- 각 sub-cluster의 fresh resolution
+- 각 sub-cluster의 latest candidate snapshot
+
+## 11. Stage 7: review / exclusion / label v2
+
+v2 Phase 1은 “자동 추론 결과”와 “사람 판단 데이터”를 분리하는 구조다.
+
+### 11.1 사람 판단 저장소
+
+- `gear_parent_candidate_exclusions`
+- `gear_parent_label_sessions`
+- `gear_parent_label_tracking_cycles`
+
+### 11.2 액션 의미
+
+- 그룹 제외:
+  - 특정 `group_key + sub_cluster_id`에서 특정 후보 MMSI를 일정 기간 제거
+- 전체 후보 제외:
+  - 특정 MMSI를 모든 그룹 후보군에서 제거
+- 정답 라벨:
+  - 특정 그룹에 대해 정답 parent MMSI를 `1/3/5일` 세션으로 지정
+  - prediction은 이후 cycle마다 top1/top3 여부를 추적
+
+### 11.3 why v2
+
+기존 `MANUAL_CONFIRMED`/`REJECT`는 운영 override 성격이 강했고, “모델 정확도 평가용 백데이터”와 섞였다. v2는 이 둘을 분리해 라벨을 평가 데이터로 쓰도록 한다.
+
+## 12. 실제 경우의 수 분기표
+
+| 경우 | 구현 위치 | 현재 동작 |
+| --- | --- | --- |
+| 이름 길이 `< 4` | `gear_name_rules.py`, `fleet_tracker.py`, `polygon_builder.py`, `gear_parent_inference.py` | identity/grouping/inference 단계에서 제외 또는 `SKIPPED_SHORT_NAME` |
+| 직접 모선 포함 | `polygon_builder.py`, `gear_parent_inference.py` | `DIRECT_PARENT_MATCH` fresh resolution |
+| 같은 이름, 멀리 떨어진 어구 | `polygon_builder.py` | 별도 sub-cluster 생성 |
+| 두 서브클러스터가 다시 근접 | `polygon_builder.py` | 하나로 병합, `sub_cluster_id = 0` |
+| group 전체 1h 활성 멤버 `< 2` | `polygon_builder.py` | `1h-fb` 생성, live 현황 제외 |
+| 후보가 하나도 없음 | `gear_parent_inference.py` | `NO_CANDIDATE` |
+| 짧은 항적이 우연히 근접 | `gear_parent_inference.py` | coverage-aware 보정으로 effective score 감소 |
+| stale old inference가 남아 있음 | `GroupPolygonService.java` | 최신 group snapshot보다 오래되면 숨김 |
+| 직접 parent가 이미 있음 | `gear_parent_inference.py` | 후보 계산 대신 direct parent resolution |
+
+## 13. `sub_cluster_id`의 한계
+
+현재 코드에서 `sub_cluster_id`는 영구 identity가 아니다.
+
+이유:
+
+1. 같은 이름 그룹의 공간 분리 수가 cycle마다 달라질 수 있다.
+2. 병합되면 `0`으로 재설정된다.
+3. 멤버가 추가/이탈해도 기존 번호 의미가 유지된다고 보장할 수 없다.
+
+따라서 `group_key + sub_cluster_id`는 “현재 cycle의 공간 덩어리”를 가리키는 키로는 유효하지만, 장기 연속 추적 키로는 부적합하다.
+
+## 14. Stage 8: `episode_id` continuity + prior bonus
+
+### 14.1 목적
+
+현재 구현의 `episode_id`는 “같은 어구 덩어리의 시간적 연속성”을 추적하는 별도 식별자다. `sub_cluster_id`를 대체하지 않고, 그 위에 얹는 계층이다.
+
+핵심 목적:
+
+- 작은 멤버 변화는 같은 episode로 이어 붙인다.
+- 구조적 split/merge는 continuity source로 기록한다.
+- long-memory는 `stable_cycles` 직접 승계가 아니라 약한 prior bonus로만 전달한다.
+
+### 14.2 현재 저장소
+
+- `gear_group_episodes`
+  - active/merged/expired episode 현재 상태
+- `gear_group_episode_snapshots`
+  - cycle별 episode 스냅샷
+- `gear_group_parent_candidate_snapshots`
+  - `episode_id`, `normalized_parent_name`,
+    `episode_prior_bonus`, `lineage_prior_bonus`, `label_prior_bonus`
+- `gear_group_parent_resolution`
+  - `episode_id`, `continuity_source`, `continuity_score`, `prior_bonus_total`
+
+### 14.3 continuity score
+
+현재 continuity score는 아래다.
+
+```text
+continuity_score =
+  0.75 * member_jaccard
+  + 0.25 * center_support
+```
+
+- `member_jaccard`
+  - 현재/이전 episode 멤버 MMSI Jaccard
+- `center_support`
+  - 중심점 거리 `12nm` 이내일수록 높아지는 값
+
+연결 후보 판단:
+
+- continuity score `>= 0.45`
+- 또는 overlap member가 있고 거리 조건을 만족하면 연결 후보로 인정
+
+### 14.4 continuity source 규칙
+
+- `NEW`
+  - 어떤 이전 episode와도 연결되지 않음
+- `CONTINUED`
+  - 1:1 continuity
+- `SPLIT_CONTINUE`
+  - 하나의 이전 episode가 여러 현재 cluster로 갈라졌고, 그중 주 가지
+- `SPLIT_NEW`
+  - split로 새로 생성된 가지
+- `MERGE_NEW`
+  - 2개 이상 active episode가 의미 있게 하나의 현재 cluster로 합쳐짐
+- `DIRECT_PARENT_MATCH`
+  - 직접 모선 포함 그룹이 fresh resolution으로 정리되는 경우의 최종 resolution source
+
+### 14.5 merge / split / expire
+
+현재 구현 규칙:
+
+1. split
+  - 가장 유사한 현재 cluster 1개는 기존 episode 유지
+  - 나머지는 새 episode 생성
+  - 새 episode에는 `split_from_episode_id` 저장
+2. merge
+  - 2개 이상 previous episode가 같은 현재 cluster로 의미 있게 들어오면 새 episode 생성
+  - 이전 episode들은 `MERGED`, `merged_into_episode_id = 새 episode`
+3. expire
+  - 최근 `6h` active episode가 현재 cycle 어떤 cluster와도 연결되지 않으면 `EXPIRED`
+
+### 14.6 prior bonus 계층
+
+현재 final score에는 signal score 뒤에 아래 prior bonus가 후가산된다.
+
+- `episode_prior_bonus`
+  - 최근 동일 episode `24h`
+  - cap `0.10`
+- `lineage_prior_bonus`
+  - 동일 정규화 이름 lineage `7d`
+  - cap `0.05`
+- `label_prior_bonus`
+  - 동일 lineage 라벨 세션 `30d`
+  - cap `0.10`
+- 총합 cap
+  - `0.20`
+
+현재 후보가 이미 candidate set에 들어온 경우에만 적용하며, 과거 점수를 직접 carry하는 대신 약한 보너스로만 사용한다.
+
+### 14.7 병합 후 후보 관성
+
+질문 사례처럼 `A` episode 후보 `a`, `B` episode 후보 `b`가 있다가 병합 후 `b`가 더 적합해질 수 있다. 현재 구현은 병합 시 무조건 `A`를 유지하지 않고 새 episode를 생성해 `A/B` 둘 다의 history를 prior bonus 풀에서 재평가한다. 따라서 `b`는 완전 신규 후보처럼 0에서 시작하지 않지만, `A`의 과거 `stable_cycles`가 그대로 지배하지도 않는다.
+
+## 15. 현재 episode 상태 흐름
+
+```mermaid
+stateDiagram-v2
+    [*] --> Active
+    Active --> Active: "CONTINUED / 소규모 멤버 변동"
+    Active --> Active: "SPLIT_CONTINUE"
+    Active --> Active: "MERGE_NEW로 새 episode 생성 후 연결"
+    Active --> Merged: "merged_into_episode_id 기록"
+    Active --> Expired: "최근 6h continuity 없음"
+    Merged --> [*]
+    Expired --> [*]
+```
+
+## 16. 결론
+
+현재 구현은 아래를 모두 포함한다.
+
+- safe watermark + overlap backfill 기반 incremental 안정화
+- 짧은 이름 그룹 제거
+- 거리 기반 sub-cluster와 `1h/1h-fb/6h` 스냅샷
+- correlation + parent inference 분리
+- coverage-aware score 보정
+- stale inference 차단
+- direct parent supplement
+- v2 exclusion/label/tracking 저장소
+- `episode_id` continuity와 prior bonus
+
+남은 과제는 `episode` 자체보다, 이 continuity 계층을 read model과 시각화에서 더 설명력 있게 노출하는 것이다. 즉 다음 단계의 핵심은 episode 도입이 아니라, `episode lineage API`, calibration report, richer review analytics를 얹는 일이다.

+
+Phase 1 범위는 아래로 제한한다.
+
+- DB 마이그레이션
+- backend API 계약
+- prediction exclusion/label read-write 지점
+- 프론트의 최소 계약 변화
+
+이번 단계에서는 실제 자동화/LLM 연결은 다루지 않는다.

+# Gear Parent Inference Workflow V2
+
+## 문서 목적
+
+이 문서는 lab 환경의 어구 모선 추적 워크플로우를 v1 운영 override 중심 구조에서,
+`평가 데이터 축적 + 후보 제외 관리 + 기간형 정답 라벨 추적` 중심 구조로 재정의하는 설계서다.
+
+대상 범위는 아래와 같다.
+
+- `kcg_lab` 스키마
+- `backend-lab` (`192.168.1.20:18083`)
+- `prediction-lab` (`192.168.1.18:18091`)
+- 로컬 프론트 `yarn dev:lab`
+
+운영 `kcg` 스키마와 기존 데모 동작은 이번 설계 단계에서 변경하지 않는다.
+
+현재 구현 기준으로는 v2 Phase 1 저장소/API가 이미 lab에 반영되어 있고, 그 위에 `015_gear_parent_episode_tracking.sql`과 `prediction/algorithms/gear_parent_episode.py`를 통해 `episode continuity + prior bonus` 계층이 추가되었다. 이 문서는 여전히 워크플로우 설계서지만, 사람 판단 저장소와 자동 추론 저장소 분리 원칙은 현재 코드의 실제 기준이기도 하다.
+
+## 배경
+
+현재 v1은 자동 추론 결과와 사람 판단이 같은 저장소에 섞여 있다.
+
+- `확정`은 `gear_group_parent_resolution`을 `MANUAL_CONFIRMED`로 덮어쓴다.
+- `24시간 제외`는 특정 그룹에서 후보 1개를 24시간 숨긴다.
+- 자동 추론은 계속 돌지만, 수동 판단이 최종 상태를 override한다.
+
+이 구조는 단기 운용에는 편하지만, 아래 목적에는 맞지 않는다.
+
+- 사람이 보면서 모델 가중치와 후보 생성 품질을 평가
+- 정답/오답 사례를 데이터셋으로 축적
+- 충분한 정확도 확보 후 자동화 또는 LLM 연결
+
+따라서 v2에서는 `자동 추론`, `사람 라벨`, `후보 제외`를 분리한다.
+
+## 핵심 목표
+
+1. 자동 추론 상태는 계속 독립적으로 유지한다.
+2. 사람 판단은 override가 아니라 별도 라벨/제외 데이터로 저장한다.
+3. 그룹 단위 오답 라벨은 `1일 / 3일 / 5일` 기간형 후보 제외로 관리한다.
+4. 전역 후보 제외는 모든 어구 그룹에서 동일 MMSI를 후보군에서 제거한다.
+5. 정답 라벨은 `1일 / 3일 / 5일` 세션으로 만들고, 활성 기간 동안 자동 추론 결과를 별도 추적 로그로 남긴다.
+6. 알고리즘은 DB exclusion/label 정보를 읽어 다음 cycle부터 바로 반영한다.
+7. 향후 threshold 튜닝, 가산점 실험, LLM 연결 평가에 쓰일 수 있는 정량 지표를 만든다.
+
+## 용어
+
+- 자동 추론
+  - `gear_parent_inference`가 계산한 현재 cycle의 후보 점수와 추천 결과
+- 그룹 제외
+  - 특정 `group_key + sub_cluster_id`에서 특정 후보 MMSI를 일정 기간 후보군에서 제거
+- 전역 후보 제외
+  - 특정 MMSI를 모든 어구 그룹의 모선 후보군에서 제거
+- 정답 라벨 세션
+  - 특정 어구 그룹에 대해 “이 MMSI가 정답 모선”이라고 사람이 지정하고, 일정 기간 자동 추론 결과를 추적하는 세션
+- 라벨 추적
+  - 정답 라벨 세션 활성 기간 동안 자동 추론이 정답 후보를 어떻게 rank/score하는지 누적 저장하는 기록
+
+## 현재 v1의 한계
+
+### 1. `확정`이 평가 라벨이 아니라 운영 override다
+
+- 현재 `CONFIRM`은 resolution을 `MANUAL_CONFIRMED`로 덮어쓴다.
+- 이 경우 자동 추론의 실제 성능과 사람 판단이 섞여, 나중에 모델 정확도를 평가하기 어렵다.
+
+### 2. `24시간 제외`는 기간과 범위가 너무 좁다
+
+- 현재는 그룹 단위 24시간 mute만 가능하다.
+- `1/3/5일`처럼 길이를 다르게 두고 비교할 수 없다.
+- “이 MMSI는 아예 모선 후보 대상이 아니다”라는 전역 규칙을 넣을 수 없다.
+
+### 3. 백데이터 축적 구조가 없다
+
+- 현재는 review log는 남지만, “정답 후보가 cycle별로 몇 위였는지”, “점수가 어떻게 변했는지”, “후보군에 들어왔는지”를 체계적으로 저장하지 않는다.
+
+### 4. 장기 세션에 대한 그룹 스코프가 약하다
+
+- 현재 그룹 기준은 `group_key + sub_cluster_id`다.
+- 기간형 라벨/제외를 도입하면 subcluster 재편성 리스크를 고려해야 한다.
+
+## v2 설계 원칙
+
+### 1. 자동 추론 저장소는 그대로 유지한다
+
+아래 기존 저장소는 계속 자동 추론 전용으로 유지한다.
+
+- `gear_group_parent_candidate_snapshots`
+- `gear_group_parent_resolution`
+- `gear_group_parent_review_log`
+
+단, `review_log`의 의미는 “UI action audit”로 바꾸고, 더 이상 최종 라벨 저장소로 보지 않는다.
+
+### 2. 사람 판단은 새 저장소로 분리한다
+
+사람이 내린 판단은 아래 두 축으로 분리한다.
+
+- 제외 축
+  - 이 그룹에서 제외
+  - 전체 후보 제외
+- 정답 축
+  - 기간형 정답 라벨 세션
+
+### 3. 제외는 후보 생성 이후의 gating layer로 둔다
+
+전역 후보 제외는 raw correlation이나 원시 선박 분류를 지우지 않는다.
+
+- `gear_correlation_scores`는 계속 쌓는다.
+- exclusion은 parent inference candidate set에서만 hard filter로 적용한다.
+
+이렇게 해야 원시 모델 출력과 사람 개입의 차이를 비교할 수 있다.
+
+### 4. 라벨 세션 동안 자동 추론은 계속 돈다
+
+정답 라벨 세션이 활성화되어도 자동 추론은 그대로 수행한다.
+
+- UI의 기본 검토 대기에서는 숨길 수 있다.
+- 하지만 prediction은 계속 candidate snapshot과 tracking record를 남긴다.

+### 5. lab에서는 override보다 평가를 우선한다
+
+v2 이후 lab에서 사람 버튼은 기본적으로 자동 resolution을 덮어쓰지 않는다.

+
+## 사용자 액션 재정의
+
+### `정답 라벨`
+
+의미:
+
+- 해당 어구 그룹의 정답 모선으로 특정 MMSI를 지정
+- `1일 / 3일 / 5일` 중 하나의 기간 동안 자동 추론 결과를 추적
+
+동작:
+
+1. `gear_parent_label_sessions`에 active session 생성
+2. 다음 cycle부터 prediction이 이 그룹에 대한 추적 로그를 `gear_parent_label_tracking_cycles`에 누적
+3. 기본 review queue에서는 해당 그룹을 숨기고, 별도 `라벨 추적` 목록으로 이동
+4. 세션 종료 후에는 completed label dataset으로 남음
+
+중요:
+
+- 자동 resolution은 계속 자동 상태를 유지
+- 점수에 수동 가산점/감점은 넣지 않음
+
+### `이 그룹에서 제외`
+
+의미:
+
+- 해당 어구 그룹에서만 특정 후보 MMSI를 일정 기간 후보군에서 제외
+
+기간:
+
+- `1일`
+- `3일`
+- `5일`
+
+동작:
+
+1. `gear_parent_candidate_exclusions`에 `scope_type='GROUP'` row 생성
+2. 다음 cycle부터 해당 그룹의 candidate set에서 제거
+3. 다른 그룹에는 영향 없음
+4. 기간이 끝나면 자동으로 inactive 처리
+
+용도:
+
+- 이 후보는 이 어구 그룹의 모선이 아니라고 사람이 판단한 경우
+- 단기/중기 관찰을 위해 일정 기간만 빼고 싶을 때
+
+### `전체 후보 제외`
+
+의미:
+
+- 특정 MMSI는 모든 어구 그룹에서 모선 후보 대상이 아님
+
+동작:
+
+1. `gear_parent_candidate_exclusions`에 `scope_type='GLOBAL'` row 생성
+2. prediction candidate generation에서 모든 그룹에 대해 hard filter
+3. 해제 전까지 계속 적용
+
+초기 정책:
+
+- 전역 후보 제외는 기본적으로 기간 없이 active 상태 유지
+- 수동 `해제` 전까지 유지
+
+용도:
+
+- 패턴 분류상 선박으로 들어왔지만 실제 모선 후보가 아니라고 판단한 AIS
+- 잘못된 유형의 신호가 반복적으로 후보군에 유입되는 경우
+
+### `해제`
+
+의미:
+
+- 활성 그룹 제외, 전역 제외, 정답 라벨 세션을 조기 종료
+
+동작:
+
+- exclusion/session row에 `released_at`, `released_by` 또는 `status='CANCELLED'`를 기록
+- 다음 cycle부터 알고리즘 적용 대상에서 빠짐

+
+## prediction 변경 설계
+
+### 적용 지점
+
+핵심 변경 지점은 [gear_parent_inference.py](/Users/lht/work/devProjects/iran-airstrike-replay-codex/prediction/algorithms/gear_parent_inference.py), [fleet_tracker.py](/Users/lht/work/devProjects/iran-airstrike-replay-codex/prediction/fleet_tracker.py), [polygon_builder.py](/Users/lht/work/devProjects/iran-airstrike-replay-codex/prediction/algorithms/polygon_builder.py) 중 `gear_parent_inference.py`가 중심이다.
+
+### 1. active exclusion load
+
+cycle 시작 시 아래 두 집합을 읽는다.
+
+- `global_excluded_mmsis`
+- `group_excluded_mmsis[(group_key, sub_cluster_id)]`
+
+적용 위치:
+
+- `_build_candidate_scores()`에서 candidate union 이후, 실제 scoring 전에 hard filter
+
+규칙:
+
+- GLOBAL exclusion은 모든 그룹에 적용
+- GROUP exclusion은 해당 그룹에만 적용
+- exclusion된 후보는 candidate snapshot에도 남기지 않음
+
+중요:
+
+- raw correlation score는 그대로 계산/저장
+- exclusion은 parent inference candidate set에서만 적용
+
+### 2. active label session load
+
+cycle 시작 시 현재 unresolved/active gear group에 매칭되는 active label session을 읽는다.
+
+phase 1 매칭 기준:
+
+- `group_key`
+- `sub_cluster_id`
+
+phase 2 보강 기준:
+
+- member overlap
+- center distance
+- anchor snapshot similarity
+
+### 3. tracking cycle write
+
+각 그룹의 자동 추론이 끝난 뒤, active label session이 있으면 `gear_parent_label_tracking_cycles`에 1 row를 쓴다.
+
+기록 항목:
+
+- 현재 auto top-1 후보
+- auto top-1 점수/격차
+- 후보 수
+- 라벨 대상 MMSI가 현재 후보군에 존재하는지
+- 존재한다면 rank/score/pre-bonus score
+- top1/top3 일치 여부
+
+### 4. resolution 저장 원칙 변경
+
+v2 이후 lab에서는 아래를 원칙으로 한다.
+
+- 자동 resolution은 자동 추론만 반영
+- 사람 라벨은 resolution을 덮어쓰지 않음
+
+즉 아래 legacy 상태는 새로 만들지 않는다.
+
+- `MANUAL_CONFIRMED`
+- `MANUAL_REJECT`
+
+기존 row는 읽기 전용으로 남겨둘 수 있지만, v2 새 액션은 이 상태를 만들지 않는다.
+
+### 5. exclusion이 적용된 경우의 상태 전이
+
+후보 pruning 이후:
+
+- 후보가 남으면 기존 자동 상태 전이 사용
+- top1이 제외되어 후보가 비면 `NO_CANDIDATE`
+- top1이 제외되어 top2가 승격되면 새 top1 기준으로 `AUTO_PROMOTED / REVIEW_REQUIRED / UNRESOLVED` 재판정
+
+## backend API 설계

+```
+
+response:

+`GET /api/vessel-analysis/parent-inference/label-sessions?status=ACTIVE`
+
+`GET /api/vessel-analysis/parent-inference/label-sessions/{id}/tracking`

+
+기존 `GroupParentInferenceDto`에 아래 요약을 추가한다.
+
+- `activeLabelSession`
+- `groupExclusionCount`
+- `hasGlobalExclusionCandidate`
+- `availableActions`
+
+`ParentInferenceCandidateDto`에는 아래를 추가한다.
+
+- `isExcludedInGroup`
+- `isExcludedGlobally`
+- `activeExclusionIds`
+
+## 프론트엔드 설계
+
+### 버튼 재구성
+
+현재:
+
+- `확정`
+- `24시간 제외`
+
+v2:
+
+- `정답 라벨`
+- `이 그룹에서 제외`
+- `전체 후보 제외`
+- `해제`
+
+### 기간 선택
+
+`정답 라벨`과 `이 그룹에서 제외`는 버튼 클릭 후 아래 중 하나를 고르게 한다.
+
+- `1일`
+- `3일`
+- `5일`
+
+### 우측 모선 검토 패널 변화
+
+- 후보 카드 상단 action area를 아래처럼 재구성
+  - `정답 라벨`
+  - `이 그룹에서 제외`
+  - `전체 후보 제외`
+- 현재 후보에 active exclusion이 있으면 badge 표시
+  - `이 그룹 제외 중`
+  - `전체 후보 제외 중`
+- 현재 그룹에 active label session이 있으면 summary box 표시
+  - 라벨 MMSI
+  - 남은 기간
+  - 최근 top1 일치율
+
+### 새 목록
+
+- `검토 대기`
+  - active label session이 없는 그룹만 기본 표시
+- `라벨 추적`
+  - active label session이 있는 그룹
+- `제외 대상 관리`
+  - active group/global exclusions
+
+### 지도 표시 원칙
+
+- active label session 그룹은 기본 review 색과 다른 badge 색을 사용
+- globally excluded candidate는 raw correlation 패널에서는 참고로 보일 수 있지만, parent-review actionable candidate 목록에서는 숨김
+
+## 지표 설계
+
+정답 라벨 세션을 기반으로 최소 아래 지표를 계산한다.
+
+### 핵심 지표
+
+- top1 exact match rate
+- top3 hit rate
+- labeled candidate mean rank
+- labeled candidate mean score
+- time-to-first-top1
+- session duration 동안 top1 일치 지속률
+
+### 보정/실험 지표
+
+- `412/413` 가산점 적용 전후 top1/top3 uplift
+- pre-bonus score 대비 final score uplift
+- global exclusion 적용 전후 오탐 감소량
+- group exclusion 이후 대체 top1 품질 변화
+
+### 운영 준비 지표
+
+- auto-promoted 후보 중 라벨과 일치하는 비율
+- high-confidence (`>= 0.72`) 구간 calibration
+- label session 종료 시점 기준 `실무 참고 가능` threshold
+
+## 단계별 구현 순서
+
+### Phase 1. DB/Backend 계약
+
+- 마이그레이션 추가
+  - `gear_parent_candidate_exclusions`
+  - `gear_parent_label_sessions`
+  - `gear_parent_label_tracking_cycles`
+- backend DTO/API 추가
+- 기존 `CONFIRM/REJECT/RESET`는 lab UI에서 숨기고 legacy로만 남김
+
+### Phase 2. prediction 연동
+
+- active exclusion load
+- candidate pruning
+- active label session load
+- tracking cycle write
+
+### Phase 3. 프론트 UI 전환
+
+- 버튼 재구성
+- 기간 선택 UI
+- 라벨 추적 목록
+- 제외 대상 관리 화면
+
+### Phase 4. 지표와 리포트
+
+- label session summary endpoint
+- exclusion usage summary endpoint
+- 실험 리포트 화면 또는 문서 산출
+
+## 마이그레이션 전략
+
+### 기존 v1 상태 처리
+
+- `MANUAL_CONFIRMED`, `MANUAL_REJECT`는 새로 생성하지 않는다.
+- 기존 row는 history로 남긴다.
+- 필요하면 one-time migration으로 legacy `MANUAL_CONFIRMED`를 `expired label session`으로 변환할 수 있다.
+
+### 운영 영향 제한
+
+- v2는 우선 `kcg_lab`에만 적용
+- 운영 `kcg` 반영 전에는 사람이 직접 누르는 흐름과 tracking 지표가 충분히 쌓여야 함
+
+## 수용 기준
+
+### 기능 기준
+
+- 그룹 제외가 다음 cycle부터 해당 그룹에서만 적용된다.
+- 전역 후보 제외가 다음 cycle부터 모든 그룹에 적용된다.
+- active exclusion list가 DB/API/UI에서 동일하게 보인다.
+- 정답 라벨 세션 동안 cycle별 tracking row가 누락 없이 쌓인다.
+
+### 데이터 기준
+
+- label session당 최소 아래 값이 저장된다.
+  - top1 후보
+  - labeled candidate rank
+  - labeled candidate score
+  - candidate count
+  - observed_at
+- exclusion row에는 scope, duration, actor, comment, active 기간이 남는다.
+
+### 평가 기준
+
+- `412/413` 가산점, threshold, exclusion 정책 변경 전후를 label session 데이터로 비교 가능해야 한다.
+- 일정 기간 후 “자동 top1을 운영 참고값으로 써도 되는지”를 정량으로 판단할 수 있어야 한다.
+
+## 열린 이슈
+
+### 1. 그룹 스코프 안정성
+
+`group_key + sub_cluster_id`가 며칠 동안 완전히 안정적인지 추가 확인이 필요하다.
+
+현재 권장:
+
+- phase 1은 기존 키를 그대로 사용
+- 대신 `anchor_snapshot_time`, `anchor_center_point`, `anchor_member_mmsis`를 저장
+
+### 2. 전역 후보 제외의 기간 정책
+
+현재 제안은 “수동 해제 전까지 유지”다.
+
+이유:
+
+- 전역 제외는 단기 오답보다 “이 AIS는 parent candidate class가 아님”에 가깝다.
+
+필요 시 추후 `1/3/5일` 옵션을 추가할 수 있다.
+
+### 3. raw correlation UI 노출
+
+전역 제외된 후보를 모델 패널에서 완전히 숨길지, `참고 제외` badge만 붙여 남길지는 사용성 확인이 필요하다.
+
+현재 권장은 아래다.
+
+- parent-review actionable 후보 목록에서는 숨김
+- raw model/correlation 참고 패널에서는 badge와 함께 유지
+
+## 권장 결론
+
+v2의 핵심은 `사람 판단을 자동 추론의 override가 아니라 평가 데이터로 축적하는 것`이다.
+
+따라서 다음 구현 우선순위는 아래가 맞다.
+
+1. exclusion/label DB 추가
+2. prediction candidate gating + tracking write
+3. UI 액션 재정의
+4. 지표 산출
+
+그 다음 단계에서만 threshold 자동화, 가산점 조정, LLM 연결을 검토하는 것이 안전하다.
