Exercise the kill-switch at least once before declaring readiness
Open, MediumPublic

Description

Turning the flag on, observing that the cross-wiki read path works, turning it off, observing that the special page cleanly becomes unavailable, and turning it back on again is the cheapest possible drill and directly satisfies the preamble readiness criterion "a kill-switch exists and has been exercised in at least one drill". The drill should be performed by whoever holds the deploy, not just described in a runbook.
