Artifacts

Artifact comment watchers can be restored after a headless resume by rescanning the transcript.

What

Background watchers that report new comments on an artifact can now be re-established when a session resumes on a host surface, by rescanning the end of the session transcript instead of relying on the newer session-record store.

Details
  • The rescan reads the transcript from a saved byte offset and refuses if the file shrank, or grew by more than 8 MB, or if the appended region does not start on a line boundary and end with a newline.
  • Only watcher records whose session id matches the current session are replayed.
  • The watcher messages gained a host-surface variant that drops the /tasks, /login and claude agents suggestions, since those commands do not exist on those surfaces.

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