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.

WalkthroughThe PR separates ChangesgRPC consumer authentication
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to Consumer authentication tokens can be exposed and reused when the client connects over non-TLS TCP, enabling consumer impersonation; consumer-owned session access also remains incomplete because Python session CRUD calls do not consistently propagate tokens. Merge should be blocked until token transport is protected or insecure token use is rejected. Sequence Diagram(s)sequenceDiagram

documentation to remove the claim that all discovery RPCs are ungated;
explicitly list only the health, status, and list RPCs that remain ungated,
while preserving the session CRUD description.
In `@packages/python/src/abbenay_grpc/client.py`:
- Around line 341-343: Add an optional token parameter to the create_session,
get_session, list_sessions, and delete_session methods, and forward it through
gRPC metadata using the same consumer-token handling as chat(). Add a client
test covering session creation followed by session_chat with the identical
token.

Summary
consumersis configured andx-abbenay-tokenis present but matches no consumer: session RPCs returnUNAUTHENTICATEDinstead of mapping the caller tolocal(#71).localfor unix-socket / local CLI DX.authorizeConsumer): missing/unrecognized token →UNAUTHENTICATED; recognized consumer lacking a capability →PERMISSION_DENIED. Denial messages stay identical so the string does not leak token validity.Why
PR #62 / DR-031 stamped sessions with an owner, but
resolveGrpcSessionOwnertreated a wrong token like no token. That let a caller with a bad consumer token use the CLI session namespace.Test plan
resolveGrpcSessionOwner(no token → local, match →consumer:<name>, wrong/empty token → fail closed, stray token with no consumers → local)UNAUTHENTICATEDand does not call the storeauthorizeConsumercodes (UNAUTHENTICATEDvsPERMISSION_DENIED)localandconsumer:full; wrong token on GetSession →UNAUTHENTICATEDCloses #71
