Screener Exits Digest

Alert ID: SCREENER_EXITS_DIGEST
Category: screener
Cross-detection: no

Weekly rollup of every name that left the screener program (ripeness-trust Wave 3, W3-3): pick-contract exits (horizon elapsed / price or regime invalidation), candidacy decay (relabeled tier_drop when a conviction downgrade was the proximate driver), and S2 evictions. ONE portfolio-level fire per week (10080min cooldown, not per-ticker — the digest engine’s own days= window is the configured floor, screener_config.json screener_alerts.exits_digest_days, default 7), reusing GET /api/v1/screener/exits’ compute_exits_digest verbatim (no new grading). Skips silently when nothing exited in the window (no spam on a quiet week). Not calibration-gated (accountability surface, not a trade-entry signal).

Severity

INFO — positive signal or notable event; no action needed

Trigger condition

{
  "type": "computed",
  "computation": "screener_exits_digest"
}

Computed condition (screener_exits_digest) — the trigger logic lives in app/signals/alerts.py:_eval_computed. This alert does not decompose into a simple field threshold; consult the source for the exact semantics.

Message template

Screener: {name_count} name(s) exited the program ({count} exit event(s)) in the trailing {days}d ({since_date} → {as_of_date}). Reasons: {reason_summary}. {never_ripened_count} never ripened, {unknown_count} unclassified.

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: 10080 minutes (~168.0 h) between fires. After the alert resolves, re-firing is suppressed until the cooldown window has passed.
• 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.
• alert_resolved webhook when the condition clears (non-cross-detection alerts only).
