Follow-up to the 2026-10-18 review of the v1→v2 migration. Start-up (finishing a pending restore, then migrating or reconciling) now runs under the lock every save takes, so a second tab's save cannot be overwritten; where no lock exists it opens unlocked, as before. The automatic backups get a size cap like Back up now's: past it the oldest are dropped, never the newest, leaving the main save room to grow. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
