Why

Protected main already validates Research Commons release candidates, but accepted product-side approval evidence is in-memory only. That leaves privacy/scientific review, rights, measurement provenance, access approval, citation metadata, separation-of-duties and manifest identity without a durable immutable record before handoff to the external public catalog owner.

What

  • Add migrations/0016_research_release_approval.sql for immutable product-owned release-approval evidence.
  • Add postgres_research_release persistence for the existing ApprovedResearchRelease domain type under READ COMMITTED.
  • Preserve exact replay idempotency and fail closed on any immutable evidence rebinding or stored-row tampering.
  • Persist all four explicit access classes and enforce canonical SHA-256, descriptive opaque references and approver/admin separation at the database boundary.
  • Add real PostgreSQL tests for insert/replay, access-class mapping, digest/metadata conflicts, tamper detection, unsupported isolation, and typed database failures.

This slice does not publish artifacts or register a public catalog entry. semantic-data-portal remains the owner of immutable public research catalog/release registration, and restricted research linkage is not introduced here.

Verification intent

  • cargo test --test postgres_research_release_persistence
  • full Runtime CI, exact statement/branch coverage, docs, security and independent review on the exact head

Base at branch creation: cc5850a0d1eacbbf16d03075534fce460a8286e6.

Summary by CodeRabbit

  • 새 기능

    • 승인된 연구 릴리스의 검토·승인 기록, 데이터셋 스냅샷, 접근 등급 및 무결성 정보를 PostgreSQL에 저장합니다.
    • 동일한 승인 증거의 재저장은 중복 처리하고, 변경된 증거는 충돌로 구분합니다.
    • 지원되는 접근 등급과 승인 정보를 검증합니다.
  • 안정성

    • 저장된 승인 기록은 수정·삭제·전체 삭제할 수 없도록 보호됩니다.
    • 누락된 저장 증거와 잘못된 참조 값, 다이제스트 및 격리 수준을 감지하고 명확한 오류 정보를 제공합니다.

Review Change Stack

Warning

Review limit reached

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

Next review available in: 57 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

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

PostgreSQL 연구 릴리스 승인 증거 테이블과 불변성 제약을 추가했습니다. Rust 저장 어댑터는 접근 등급, 격리 수준, 중복 재실행, 충돌 재실행과 누락된 저장 증거를 처리합니다. 통합 테스트는 저장 계약, 변조 감지와 오류 매핑을 검증합니다.

research_release_approval 테이블에 참조 필드, digest, 접근 등급, 승인자 분리와 생성 시각 제약을 추가했습니다. UPDATE, DELETE와 TRUNCATE는 55000 오류를 발생시키는 트리거로 거부합니다.

모든 접근 등급의 초기 저장과 중복 재실행을 검증합니다. 증거 필드 변경, 데이터베이스 변조, UPDATE·DELETE·TRUNCATE, 누락된 저장 증거, 격리 수준과 오류 전파를 검증합니다.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 68796

The change adds durable immutable approval evidence, but its immutability test only checks that a database error occurred and does not prove the protected row was rejected for the intended reason. Merge should wait for a more specific assertion or explicit owner acceptance of this bounded correctness risk.

Please fix the exact-head Runtime CI branch-coverage blocker on 03bde461f972932b20e845cb22abb8a100de9ebf against protected main cc5850a0d1eacbbf16d03075534fce460a8286e6. Run 31801864327 has production line coverage and format/lint/tests/rustdoc green, but production branch coverage job 94771471899 fails the repository's exact 100% gate. Identify the first uncovered production branch, add or correct realistic fail-closed evidence rather than weakening/excluding the gate, keep semantic-data-portal ownership unchanged, and do not merge. After updating, leave the branch for fresh exact-head CI/review.

저장 행 부재 시 오류 매핑을 확인하십시오.

ON CONFLICT ... DO NOTHING이 0행을 반환하면 query_one이 정확히 1행을 요구합니다. 현재 마이그레이션의 불변 트리거가 DELETE를 차단하므로 행은 남아 있습니다. 그러나 TRUNCATE나 트리거 비활성화 경로에서는 0행이 가능하고, 그 경우 ConflictingReplay가 아니라 Database로 매핑됩니다.

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

  • Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

  • Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

  • Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

  • Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

  • Result: REQUEST_CHANGES

Head e95d447 persistence kernel is sound: query_opt + MissingStoredEvidence, TRUNCATE guard, SQLSTATE 55000, and tamper-column whitelist are in place. OpenCode CHANGES_REQUESTED on 687960e is stale coverage-evidence from an older head.

Do not merge this head. Recovery still copies only outbox/inbox/consumption/response snapshots, so a restored store can lose approved Research Commons evidence and will not prove the immutability guard survived COPY. TRACEABILITY still marks research-release manifests as Target, CHANGELOG/ERD/UML/Research Commons governance omit research_release_approval, and there is no independent database CHECK coverage for numeric identity, whitespace, digest, access class, or shared approver/admin.

Those gaps are implemented on cursor/bc-47f93277-ffe5-4ddf-bb77-ce962ce10d26-d732. Merge that successor after exact-head CI and independent review. Keep semantic-data-portal as the catalog owner.

Recovery seeds and copies outbox, inbox, consumption, and response snapshots only. Migration 0016 creates research_release_approval, but a clean restore never copies that row and never asserts that UPDATE still fails with SQLSTATE 55000. Add the approval fixture to the seed, the COPY table list, and the restored-evidence assertions before merge.

### Active implementation work that is not protected-main truth

**Active PR** #76 data-rights processing-start persistence is not protected-main truth until an unchanged reviewed/check-clean head is integrated. Identity-verified requests persist an immutable operation identity and processing-start time under `FOR UPDATE` so later lifecycle composition cannot race the classified row. Dependent-system execution remains outside this slice.
**Active PR** #71 research-release persistence is not protected-main truth until an unchanged reviewed/check-clean head is integrated. Immutable release approval evidence is persisted with exact replay and fail-closed rebinding. Public catalog presentation remains outside this slice.

This Active PR note is not enough for a material persistence slice. The evaluated-main matrix still says research-release manifests are Target, the source/migration tree omits postgres_research_release.rs and 0016_research_release_approval.sql, and ERD/UML/CHANGELOG/Research Commons governance still describe only the later catalog research_release. Record the product-owned approval evidence as Active PR implementation, distinct from semantic-data-portal registration.
