The multi-measure trigger fixture is a cert the sized ASHP alone cannot clear 🟩

Browse source 
Golden cert 0330 now reaches band C on the dwelling-sized ASHP alone
(ADR-0049), dropping its solid_floor_insulation companion; cert 0390
still fires three measures, so the per-measure trigger-attribute
assertions move there (and gain the lighting triggers).
