How to read this

Pick a day, press play. Each frame is one hour (UTC). Every colored point is a place the system flagged as high risk 12 hours before that hour began. When the interference channel actually lit up there, the point earns a pulsing ring — a verified call.

We show the whole record: false alarms stay on the map, and blue points mark interference we did not flag. The precision figure in the bar below is computed over every flagged point of the day — nothing is cropped to flatter the score.

Positions are shown at ~110 m display resolution. The published file behind this page carries only what you see: position, risk, outcome.

Day precision here is computed at the 0.5 display threshold over every call shown; the ledger precision figure in our documents is computed on the gradeable forward record under its own pre-registered rules — the two are different, deliberately conservative views of the same forecasts.
