"""Slice 12 — actor × target authz matrix for ``POST /key/delete``.

Same shape as Slices 10/11: master-seed a scoped scratch key, the actor under
test attempts to delete it via ``POST /key/delete {keys: [<cleartext>]}``. On
200 the test verifies the row is gone (or soft-deleted) AND the cleartext can
no longer auth. On denial it verifies the row survives and still authenticates.
