The record backed-up reads is the key `<module>.<item>` of the module's own state put-off (key-ttl), bounded by the setting put-off-bound (minutes, default 60); the bus removing it is heard as the expiry, which writes the finding backup-waits through the held writer over the module's findings and ends the wait, so the night never holds its lock without a bound. The file put-off.json and its writes are gone. The manifest requires put-off, findings and finding-events and hears findings-asked.
