nox records the hand act a sensitive vault verb is warranted by

Each sensitive vault verb judges its own caller, and nox reaches the vault
as its machine's runtime, never as a person, so it could use none of them.
Before rotate, retire approve, cleanup delete and secret export nox records
the act through mesh-hand-acts (the vault verb as its verb, what it acts on
as its what) and names it as act; a refused recording calls the vault not at
all (ADR 0590 §8, issue 1126 review 1).
