What

The periodic reminder about dispatched background work now identifies itself as worker-checkin rather than coordinator-worker-checkin, in both the notification and the code that matches on it.

Details
  • The scheduler call replaceCoordinatorWorkerCheckin became replaceWorkerCheckin and now records intervalMs.
  • Nearby, new subscription helpers appear for sessionAgentNameChanged and sessionTitleChanged.
Evidence

worker-checkin, e.origin.source === "worker-checkin"

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
