About
Registry Backup (hg-regbak-01) is a scheduled droid owned by Hagrid whose job is to keep Carol's registry crown-jewel recoverable. Every six hours it takes a rolling snapshot of registry.db, so that even if the live database gets clobbered, the last good snapshot survives and can never be overwritten. It exists precisely for that worst case: a corrupted or collapsed registry must not destroy the recovery path.
It works by using SQLite's online-backup API to copy the database while it's live, independently of any relay. It refuses to snapshot a stub or collapsed registry, and it writes the last-good manifest that the Collapse Guard later uses as its baseline. Registry Backup is the only droid in the backup family currently running โ family size is one โ and it belongs solely to Hagrid; its name is unique rather than a shared template other agents run. See Droid Families for how droid families are tracked.
Its execution engine isn't recorded yet (no source has been located), so the detected engine is unknown โ nothing is confirmed about whether it runs as pure software or calls Claude.
