- ProfilePreparation.catch_up_backup carries the file name of the copy as
soon as it exists, so the Journal error line of a catch-up that stops
afterwards (history_write_failed, pragma_failed, apply_pending) names it.
- Error lines and the JS fallback message keep only the last segment of a
path (withoutFolders): no error line contains a slash or a backslash.
- The copy is taken again at every catch-up, written as .tmp, synced and
renamed over a same-name copy; after a successful catch-up only, the
other copies of that profile are pruned (remove_backups keep argument).
- Pins: a pre-existing foreign key violation in the profile without
category 31 (RV4, RV7) and the Journal line that reports it (RT2).
- Ignored test measuring prepare_at on 100 000 transactions at floor 6:
306 ms in release, so STARTUP_TIMEOUT_MS stays 10 s (ADR 0021).
- Guide, docs.profiles.tips, ADR 0021, architecture and changelogs.
