Why declareddeclareHybrid
Incident declaration (deterministic floor + LLM relevance gate)v1
DECLARE when deterministicFloor AND (llm.declare OR acuteWeatherFloor) AND NOT aggregateTitle, and no open same-domain incident merges it. deterministicFloor = maxSeverity>=8 AND (newsScore>=1 OR bpoScore>=1 OR acuteWeatherFloor). acuteWeatherFloor = maxSeverity>=9 AND any signal is an acute severe-weather WARNING (tornado/severe-thunderstorm/flash-flood) — overrides the LLM footprint-based suppression. aggregateTitle (grab-bag "Multiple/Several/Various…") is refused (agents-019 §D). Asset-class deny (military/war-zone, WFM-37) suppresses earlier. cyberFloor disabled (agents-009 hotfix).

Why SEV3SEV3score 3Deterministic
Incident severity level (SEV1–SEV4) at declarationv1
Base: SEV2 if sev>=9 AND news>=2 AND bpo>=1; else SEV3 if sev>=8 AND (news>=1 OR bpo>=1); else SEV4. Acute severe-weather (agents-028): if sev>=9 floor to SEV3 (SEV2→SEV3); minor/transient watches+advisories drop SEV2/SEV3→SEV4. Single-event cap: any SEV2 caps to SEV3 absent sustained multi-day BPO-region corroboration (SEV2 promotion is human-gated via revalidation). score = numeric SEV (1=most severe … 4); SEV3/SEV4 auto-validate, SEV1/SEV2 require human validation.
