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 within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

📝 WalkthroughWalkthroughAdds an observed dashboard connect handoff helper with bounded output capture, forward-start detection, process-group cleanup, timeout and cancellation handling, artifact persistence, and result reporting. Updates remote-bind E2E coverage with forward status and TCP reachability checks. ChangesDashboard Connect Handoff
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR changes dashboard E2E process handoff and cleanup behavior. Current failure paths can expose connect output in CI logs and leave a detached test process running, creating bounded diagnostic and runner-resource risks; merge should wait for these safeguards or explicit owner acceptance.

57-77: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winMake the "before spawning" claim observable.
The test title states that validation rejects the call before it spawns connect. The assertions prove only that the promise rejects with the expected message. They pass equally if the helper spawns first and validates after. Give the command an observable side effect and assert the side effect never occurs.
♻️ Proposed change to assert no spawn occurred

In `@test/e2e/live/dashboard-remote-bind.test.ts`:
- Around line 187-199: Update the assertion for connect.proof in the dashboard
handoff test to remove inline connect.stdout and connect.stderr from the failure
message, and instead reference the existing dashboard-connect-handoff.stdout.txt
and dashboard-connect-handoff.stderr.txt artifacts produced by
runDashboardConnectUntilForwardHandoff. Keep child output bounded and redacted
in artifacts only.
In `@test/e2e/support/dashboard-connect-handoff.test.ts`:
- Around line 113-121: Update the finally cleanup in the handoff test to fail
explicitly when no valid positive cleanup PID can be obtained from forwardPid or
pidFile, instead of resolving silently; retain stopFixtureProcess for valid PIDs
and ensure cleanup remains bounded and failure-propagating.

Summary
Refs #9606. Stacked on #9323.
Related delivery: #9140. Related epic: #7744.
The dashboard remote-bind target recovered a missing forward successfully, then waited for ordinary interactive
nemoclaw connectto exit before evaluating the already-emitted recovery proof. The shell remained attached by design until the generic command timeout killed its process group, changing the historic no-exit result into exit 143 and preventing the target from reaching its independent bind and audit assertions.This change observes the real connect child asynchronously. Once the existing forward-recovery proof appears, it signals and reaps only the attached connect leader and requires its captured descriptors to close without forced cleanup. A correctly backgrounded forward remains live for the existing exact owner, all-interface bind, reachability, and security-audit verification. Ordinary interactive and noninteractive
connectbehavior is unchanged.Changes
