## 요약

Identity map idempotency/retry follow-up loop 2에서 atomic identity conflict handling과 strict retry identity key를 보완하고 최종 PASS로 종결했다.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_cloud_G07_0.log` | `code_review_cloud_G07_0.log` | FAIL | identity upsert rebind race와 retry identity tenant/project mismatch 문제로 follow-up 작성 |
| `plan_cloud_G07_1.log` | `code_review_cloud_G07_1.log` | PASS | conditional upsert conflict mapping과 strict retry identity tests 확인 |

## 구현/정리 내용

- `UpsertRoadmapSyncIdentityByWorkItem`의 `DO UPDATE`를 기존 Milestone path와 incoming path가 같을 때만 실행하도록 바꾸고, path 재바인딩 no-row와 unique violation을 `ErrRoadmapSyncIdentityConflict`로 변환했다.
- store의 비원자적 선조회 기반 conflict check를 제거하고 SQL statement 단위 conflict handling으로 정리했다.
- `Identity.MatchesStrict`를 추가하고 `ReconcileCreationCycle`에서 provider, tenant, project, work item id, Milestone path를 모두 비교하도록 보완했다.
- rebind/no-row, path unique violation, generic DB error propagation, tenant/project mismatch 테스트를 추가했다.

## 최종 검증

- `cd services/core && ./bin/sqlc` - BLOCKED; 기존 `queries/workspace_slots.sql:19:11` ambiguity로 실패, 이번 신규 query와 follow-up 범위 밖 차단으로 기록됨.
- `cd services/core && go test -count=1 ./internal/storage ./internal/roadmapsync ./internal/adapters/plane` - PASS; storage, roadmapsync, Plane adapter targeted tests 통과.
- `cd services/core && go test ./...` - PASS; core 전체 Go test 통과.
- `cd services/core && go vet ./internal/roadmapsync ./internal/storage ./internal/db` - PASS; 출력 없음.
- `cd services/core && gofmt -l internal/roadmapsync internal/storage internal/db` - PASS; 출력 없음.
- `git diff --check` - PASS; whitespace 오류 없음.
