Warning Review limit reachedYou’ve reached a temporary PR review limit under our Fair Usage Limits Policy. Next review available in: 32 minutes Limit details: You’ve used all 3 included reviews currently available under your plan. You completed 70 included PR reviews in the past 7 days; at that activity level, included reviews refill at 3 reviews per hour. Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available. 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.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The media reliability changes are mergeable with owner awareness, but timing diagnostics still need focused checks for recorded values and early-return paths, and cancellation behavior should be asserted precisely to prevent regressions.

In `@docs/api/methods.md`:
- Line 759: Update the response examples in the API methods documentation to
include the required hasCover field on every BrowseEntry, including the root
example and browse-path entries. Use boolean values consistent with each entry’s
available image properties so the examples match BrowseEntry serialization.
In `@pkg/api/methods/media_image.go`:
- Around line 903-928: Add focused tests for the timing instrumentation in
pkg/api/methods/media_image.go lines 903-928, covering successful and
validation-error HandleMediaImage requests and asserting ok, delivery, and
mediaId fields. In pkg/api/methods/media_image.go line 937, verify the timing
log records the snapped thumbnail size. In pkg/api/methods/media_meta.go lines
39-57, test single, batch, parse-error, and downstream-error requests, asserting
batch, itemCount, and ok fields.
In `@pkg/database/mediadb/sql_browse_cache.go`:
- Around line 554-562: The sqlInvalidateBrowseCache upsert must not create a
version row when DBConfigBrowseIndexVersion is absent; restrict the update to
existing rows whose value is browseCacheSchemaVersion or
browseCacheInvalidatedVersion. Add test coverage for a missing version row with
existing BrowseDirs rows, verifying the cache remains incompatible and is not
served.
In `@pkg/database/mediadb/sql_browse.go`:
- Around line 1555-1595: The sqlBrowseDirectFileCountFromCache path must not
treat partial BrowseDirCounts self-row aggregates as complete totals. Track or
validate coverage for every requested system, and return control to
sqlBrowseFileCount’s sqlBrowseFileCountFromMedia fallback whenever any requested
or unfiltered system lacks a complete self-row; preserve cache use only for
complete coverage. Add regression tests covering an unrefreshed system and an
unfiltered request after refreshing a single system.

Add tests for the new handler timing instrumentation. Both handlers add new logging code without focused tests for its metrics and error-path behavior.

- Return a non-timeout error from the route
COUNT(*)query and assert propagation.- Cancel the caller context during the route query and assert that fallback does not occur.
Existing tests cover timeout, probe timeout/error, probe reuse, and cancellation during the probe.

so every event asserts that the duration field is present. Do not require a
positive duration value; zero must remain valid.
