Descriptive alerts only (ALERT_POLICY_V1, policy 9cfc4be4420d…, monitor config 74276a3f4c21…). An alert is an accepted M14 attention reason that reached its versioned display threshold; thresholds are not optimized against outcomes. Category order is review order, never expected profitability. Seen / acknowledged / dismissed are your workflow states, not trading states. Options-derived alerts describe the current selected contract set, not whole-market flow. Nothing here is a recommendation, prediction or score.
