Qscore score changed

A newly generated Qscore report produced a score different from the subject’s previous known score (e.g. on a monitoring re-pull or a new purchase). Emitted only when the score actually changes; the payload carries the old and new score/band pair so you can decide whether to act. Subscribe to this event to monitor a subject over time without polling.
