Elevated (≥ high-risk) episodes paired with salient audiences, ranked by the compound priority score (compound_priority_v1) — 499 strategy objects. Behavioural fields are design templates (tagged in evidence_basis), and every object is ex_post — reconstructed from realized data, claiming no advance notice.
