Hi team , I opened PR #14031 to prevent a node from being published

Online

before its gRPC listener is ready. I confirmed the startup ordering could signal initialization before Tonic bound the gRPC socket, leaving a brief window for distributed queries to select an unreachable node. The fix binds the listener first, then reports readiness, and adds coverage for successful readiness and bind failures. CI is running.

Thanks for the fix and detailed validation! we'll take a look at the PR.
