A soft nudge advisory belongs to one continuous on-task stretch in an allowed app. Guard it with an on-task-stretch epoch (advanced on session reset and on any non-on-task-match observation) instead of a session-only counter, and clear the advisory on leaving the allowed app, so a stale 'Heads up' never resurfaces after a drift episode.
