Message template

SKEW at {skew_close:.0f} — extreme tail-risk pricing, markets bracing for large move.

Rendered with the current signals dict via Python str.format. Placeholders that fail to resolve fall back to the raw template (see _format_message in app/signals/alerts.py).

Cooldown / dedup

• Cooldown: none. Re-evaluation on every cycle.
• Dedup: at most one active (or acknowledged) row per alert_id at a time. Re-firing while active updates fired_at and the message but keeps the original first_fired_at.

Notifies

• Active alert feed (/api/v1/alerts/active, /alerts/summary).
• SSE stream (/api/v1/agents/stream) for real-time consumers.
• alert_fired webhook on first fire (critical-tier).
• alert_escalated webhook (critical-only).
• alert_resolved webhook when the condition clears (non-cross-detection alerts only).
