The editor and the engine write to the same row from different threads, so an
edit is a transaction: read, transform, write back, with the id and the
creation stamp forced from the stored row. Without it the editor would
re-enable an alarm the engine had just resolved as disabled, or move a row's
history.
`AudioSourcePolicy` is where the silent sentinel becomes an empty source list
— the audio player then fails to start by design, and the ring falls through
to vibration instead of to nothing.
