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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WzxdWXdsB7CQPNXVN829G1
