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.

Found one merge-blocking concern in The current implementation rebuilds a fresh adapter map for every provider invalidation: providers := r.providerRepo.GetAll()
next := make(map[uint64]provider.ProviderAdapter, len(providers))
// factory(p) for every provider
r.adapters = nextThat makes a peer-side provider reload much broader than the changed provider. Any provider update can replace every runtime adapter instance, including unchanged Codex/custom providers. Those adapters own runtime state such as Responses WebSocket continuation sessions; replacing the instance drops that state and can leave existing upstream websocket sessions unreachable until their own timeout/cleanup. It can also disrupt unrelated in-flight/continuation requests even though only one provider changed. Suggested fix: reconcile incrementally instead of wholesale replacement:
The current tests cover the happy path for a newly-created provider becoming matchable on another instance, but not the state-preservation case for existing adapters. This is risky in the provider adapter / websocket request path, so I would not treat this as merge-ready without tightening that behavior. |

Approved after re-review: conflict-free, required checks passed, and the adapter reconciliation regression concern is addressed with incremental preservation plus targeted tests.
