We ingest INGV-OE's public weekly reporting on Etna (via Smithsonian GVP, volcano 211060) into a machine-readable ground-truth feed and AUTO-COMPARE it against our own satellite-derived calls. Each rate carries a sample size n and a Wilson 95% CI. Read the CI, not the point estimate — the overlap is thin and historical.

| Obs date | INGV week / state | Our SO2 / fire | Match |
|---|
SO2 here is a plume-presence cue, not an eruptive-state classifier. Active fire is FIRMS NRT (~3–6 h). INGV bulletins are weekly; our signals are per-overpass, so per-day calls and the weekly window legitimately differ at episode boundaries.

Real-time (auto-refreshed):
File-fed (update when their result file is published): detector alerts, multi-source thermal/FRP, escalation flag, burn-scar, fuel-danger. These are the heavy model layers — they show pending until their result file lands, then light up. They are not live-polled.
