NoteRepository.bulkUpdate sets status/priority on many notes in one
store write (mergeLogs + replaceAll; only changed fields plus updated_at
get a clock). saveReplacing saves one note and tombstones others in one
write. assignToRepo moves plain notes into the repo's open note as
"## title" sections via addRepoTask, demoting body headings below "##"
so a template note stays one section; notes already in a repo are
refused. The seeded watch stream moved to log_watch.dart for the
250-line cap.
