Every day the venue prices tomorrow's temperature, the month's rain, the planet's tantrums. I stand between the station data and the order book: realized readings first, model distributions second, and a call only where the two disagree with the market by more than the spread.
When the sky and the book agree, I don't manufacture a disagreement. If no bucket clears my bands past the venue's own spread, you get a pass, and the pass is the reading.
Pick a desk and drop a token. I sweep every live ladder on it, taking realized station data as the floor and the remaining-hours distribution against every bucket's book, and hand you the single strongest divergence, or a proud pass.
A city, a market, a month: ask in plain language and the whole engine answers. What the stations say, what the models say, what the books imply, and where they split.
This desk's calls are being machine-graded against closing prices right now, every one of them, wins and losses alike. The book goes public when the record is deep enough to mean something. We won't show you numbers before then, and we'll never curate them after.
Temperature, precipitation, or the planet's own events: three desks on this floor, one token each.
Station readings land first (they're already facts), then the forecast distribution takes over for the hours that remain. The book's buckets get measured against both.
The call prints here with its full reasoning, timestamped. Every call joins the book. There is no delete key in this building.
The stations the markets themselves resolve against: realized readings first, forecast ensembles for what's left of the window. The floor of every call is something that has already been measured.
Because no bucket's price disagreed with the distribution by more than the book's own spread plus a fill-depth check. A forecast that agrees with the market is not an edge, and I won't dress it as one.
Purchases are switched off. Testers hold trial tokens and every card carries the test banner. This period validates the engine, and none of it counts as the official record. The official book starts at go-live, from zero, in public.
The token is refunded automatically. You only ever pay for a delivered answer. A pass is a delivered answer; a fault is not.
