The user-driven verification matrix for the whole advancement chain on a
scratch character: live run-speed change under a Quickness raise, the
Endurance single-record stamina fan-out, the deliberate raise-10 failure
probe that resolves the narrowed AP-73 ghost question, skill raise/train,
gem-driven specialize/lower with the confirmation dialog, and a
regression sweep. CA1-CA4 are committed and pushed; this script is the
campaign's remaining gate.
