Warning

Review limit reached

@boul2gom, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 33 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

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.

Please refer docs for additional details.

In `@docs/self-hosting/govern/reverse-proxy.md`:
- Line 228: Update the reverse-proxy route table entry to match the examples’
default public upload path, documenting `/uploads` as the route to plane-minio
on port 9000; if retaining the configurable bucket-name route, add the required
rewrite behavior consistently across the documented proxy configurations.
- Around line 260-268: Add proxy_http_version 1.1; to the /live/ WebSocket
location block alongside the existing proxy_pass and upgrade headers, preserving
the rest of the reverse-proxy configuration.
- Line 346: Update the Traefik router rules in the documented reverse-proxy
configuration to use exact root matches plus trailing-slash prefixes instead of
broad PathPrefix matchers. Apply this boundary-safe pattern consistently to api,
auth, static, god-mode, spaces, live, and uploads across the affected rules,
preserving the existing Host condition.
