Term	Kind	Topic	What it is
Deletion Propagation Purge Fanout, Erasure Propagation	pattern	Retention & Purge	The mechanism that carries a deletion from the primary store to every derived copy - which is where retention and erasure obligations are actually met or missed.
Deletion Verification	practice	Retention & Purge	Proving that a deletion actually removed the data everywhere it existed, which is a harder problem than issuing the delete.
Erasure Amplification Deletion Write Multiplier, Purge Fan-Out	concept	Retention & Purge	The ratio between the bytes rewritten to honour a deletion request and the bytes actually belonging to the subject, which decides whether on-demand erasure is feasible or must be batched.
Retention and Purge	practice	Retention & Purge	Deleting data when its lawful or business purpose has ended, and being able to prove that it happened.
