How can I continue?After more reviews become available, a review can be triggered using the 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.

📝 WalkthroughWalkthroughPostgreSQL 18 기반의 참가자별 동의 원장과 추가 전용 이벤트 저장을 추가했다. 멱등 재생, 충돌 이벤트 거부, Changes동의 영속성
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🟡 Moderate · up to The change adds PostgreSQL consent ledgers and events, but the current schema does not tie ledgers to persisted participants or enforce tenant ownership at the database boundary. This could allow orphaned or incorrectly scoped records, so merge should wait for the ownership foreign key and corresponding tenant-scope coverage; the append-only wording should also match the actual enforcement.

Store participant-bound consent ledgers and append-only grant/revoke events with exact replay, independent research-scope shape, and fail-closed conflicting event identity.
Fail closed when a consent timestamp exceeds PostgreSQL bigint, when the event relation is missing after ledger insert, and when replay SELECT is redirected off the live search path.
CI branch coverage failed at 556/560 because replay conflict only rebound the form version. Independently mismatch purpose, decision, research scope, and occurred-at so each AND branch fails closed.
