Both marked SHIPPED + PROVEN-LIVE in OPEN-ITEMS and the campaign doc. All three
of Campaign 8's alarm findings are now closed (F-CRIT-1, F-CRIT-2, F-A1).
Adds the standing rule earned by this arc to the versioned workspace CLAUDE.md:
a comment asserting an invariant needs a test pinning it, or it is a wish — with
all six shipped-false-guarantee instances catalogued, and the corollary that a
test should assert the CONSEQUENCE (does the alarm fire?) not the MECHANISM
(does suppression expire?).
