Periodically updated feed delivery Manually published USGS reported earthquakes and NOAA GFS model forecasts. No scheduled acquisition is active. Updates reach this site only through a verified static deployment.
Check published feeds No publication checked in this session.
Air quality — PM2.5 DISABLED — provider licence review required. OFF in the public build. No provider readings are loaded. AQI: UNKNOWN.
Damage, loss, inundation and casualties: UNKNOWN.

Live contract verification Feature 42 prepares contracts for periodically updated conditions. Source acquisition is not configured in this feature.
Inspect synthetic contract cases SYNTHETIC FIXTURE — not current conditions. These cases contain no measurements or locations. Every timestamp and workflow result is a fixed test input, not an actual fetch.
Scenario / educational estimate, not a forecast or warning
