Keep an approval asked through a silence of its condition (hq ADR 0259, the confirmation review's M1)

Choosing Silence silenced the condition, the condition was no longer wanted, and the next reconcile
cancelled the Restart or Release ask beside it: an acknowledgement, which any desk click may give,
took an approval back. An open approval ask now stays until it is answered or expires while its
condition is open and silenced with the same answers. The test silences as the controller does; it
failed before (0 open) and passes, and the kept Restart is performed on its warrant.
