Wait for the free limit to reset to keep reviewing this public repository. 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.

- Around line 109-112: Update setExpectedPackages() to normalize each incoming
package by cloning it and removing properties whose values are undefined before
comparing or assigning. Use the normalized package collection for both _.isEqual
against this.#expectedPackages and the this.#expectedPackages assignment,
preserving change detection based on the MongoDB-persisted shape.
In `@packages/job-worker/src/ingest/model/implementation/IngestModelImpl.ts`:
- Around line 593-642: Extend NotificationsModelHelper with a pending-change
indicator and expose it to IngestModelImpl, then update `#findFirstChange`() to
return a change error when notifications have unsaved changes. Ensure
hasChanges() and assertNoChanges() detect notification-only updates before
saveAllToDatabase() persists them, and add an ingest test covering persistence
when only a notification changes.

This is a: Bug fix / Feature
Current Behavior
We have identified a few cases where an ingest update can trigger a series of unnecessary react renders. The impact is likely not all that large, but it is unnecessary work and easy to stop
New Behavior
The full DBRundownPlaylist was being passed as a prop to each SourceLayerItem. These components made no use of it, and the playlist and so do not need its reactivity. This prop has been dropped where possible.
The DBRundownPlaylist being passed around the ui had unused and noisey properties such as the modiifed timestamp changed following each ingest operation. A ui now queries a smaller shape to avoid this noise and passes a more minimal type around.
After the blueprint
getSegmentwas called for a segment, Sofie was not diffing the segment to see if it actually changed before writing it to mongodb. Sofie is now doing a deep diff of the segments, allowing ops which fire often and make no changes to terminate quicker inside the ingest thread, and avoid attempting to touch playout or push any publication updates to the ui.Added a
partChangedproperty to theBlueprintSyncIngestNewData, to allow blueprints to easily identify if the Part that thesyncIngestChangesis running for has any ingest changes to sync.Testing
