A calm room stays calm
Movement, cooking, steam — Pyra watches without raising a single alarm. This is the hard part, and where it earns its keep.
Fire appears — and is seen
The instant flame is visible, per-frame detection lights up. The state moves to SUSPECTED — but no one is alerted yet.
Confirmed, then alerted
Only once the fire persists across frames does Pyra confirm it — and raise an evidence-backed alert in seconds. That two-stage check is why it doesn't cry wolf.
