Redundancy Copies Your Mistaken Delete Within a Second; Only a Backup Undoes It

The curation's outcome names two ways an application betrays you, going away and being wrong, and this node is where that distinction lands on the database's own safety mechanisms. It presupposes the standby and replica nodes for what redundancy does and the snapshot-and-log node for what a restore does, and it is the failure of judgement most likely to be held by a learner who has just finished those nodes. Its Apply question, classifying incidents by which mechanism recovers them, belongs to no other node in the sub-domain.
