fix(data-rights): keep creation replay idempotent after lifecycle advance

[seonghobae]

Why

The durable request creation replay classifier currently compares mutable lifecycle state and latest_event_at_unix_ms in addition to immutable creation evidence. Once the same request advances to identity verification, an otherwise exact retry of the original creation command is therefore misclassified as ConflictingReplay. That turns a transport/retry-safe creation contract into a state-dependent failure even though request identity, scope, propagation targets, and immutable outbox evidence have not changed.

What

• Add a PostgreSQL regression test that creates a request, durably advances it to identity_verified, then retries the exact original creation command and requires Duplicate.
• Classify request creation replay from immutable creation evidence (tenant_ref, participant, kind, scope, requested time) plus the existing exact target/outbox evidence, not mutable lifecycle state/time.
• Preserve fail-closed behavior for changed request evidence or propagation targets and continue requiring a caller-supplied domain request in Requested state.

Test-first evidence

• RED: 595f05b30a089f2275b40864779751ef6621b345 (test(data-rights): preserve creation replay after lifecycle advance)
• GREEN: 4e88de15d8ad332c0b904eb2174c52a2322564c2 (fix(data-rights): decouple creation replay from mutable lifecycle)
• Required exact-head PostgreSQL/runtime/coverage/security/review checks must pass before merge.

Summary by CodeRabbit

• 버그 수정

  • 데이터 권리 요청이 처리 단계로 진행된 후에도 동일한 요청을 재시도하면 중복 요청으로 정확히 처리됩니다.
  • 신원 검증이 완료되거나 후속 상태로 전환된 뒤 동일한 검증을 재시도해도 중복으로 인식됩니다.
  • 저장된 검증 증거가 일치하지 않는 경우에는 충돌로 처리되어 잘못된 재처리를 방지합니다.

• 테스트

  • 다양한 상태 전환 이후의 요청 및 신원 검증 재시나리오를 검증하는 테스트를 추가했습니다.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 9 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

데이터 권리 요청 재생 판정이 현재 lifecycle 상태 대신 영속 요청 식별 정보와 신원 검증 증거를 사용하도록 변경되었습니다. PostgreSQL 테스트는 lifecycle 진행 후 동일한 요청과 검증 재생이 Duplicate로 처리되는지 확인합니다.

Changes

데이터 권리 재생 처리

Layer / File(s)	Summary
영속 증거 기반 재생 판정 src/postgres_data_rights.rs	요청 재생은 요청 식별 정보와 최초 요청 시각을 비교합니다. 신원 검증 재생은 저장된 검증 증거와 검증 시각을 비교합니다. 현재 lifecycle 상태와 최신 이벤트 시각은 판정에서 제외됩니다.
lifecycle 진행 후 재생 검증 tests/postgres_data_rights_creation_replay.rs	요청과 신원 검증을 저장한 뒤 상태를 진행합니다. 동일한 요청과 검증을 재실행할 때 Duplicate가 반환되는지 검증합니다.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 81d7f

The change preserves creation retries after lifecycle advancement, but the new database test can fail when tests run in parallel because multiple invocations may use the same schema name. Merge should wait until the test fixture uses a per-invocation unique schema.

per-invocation nonce, rather than relying only on std::process::id(), so
parallel tests always use distinct schema names. Ensure the fixture cleanup
drops that generated schema when the test ends, while preserving the existing
