Record the staged retail A/B: FIFA consumed the Rust squad path end-to-end
(userMassInfo overlay, in-game swap -> squad-replace {"id":0}, formation
f442->f433 persisted to Core, cold relaunch returned the persisted squad),
with Python rollback / Rust re-enable proven by host-log presence. Note the
OPENFUT_DEV_CONTENT_GAMES=fifa17 startup requirement (silent empty /collection
if omitted) as a needed deployment/preflight assertion.
