Preamble
Anyone can claim to have predicted an outcome after it is known. The credibility of a forecast lies entirely in when it was made, whether it can still be changed, and whether every forecast — not a chosen few — stands in the record. Yet in nearly every field where predictions are sold, none of these three things can be established by the public.
This standard defines the minimum requirements for a prediction to be called verified: sealed before the event, anchored in time beyond the forecaster's control, graded against the official result, and preserved — hits and misses alike — in a record that no one, including its author, can rewrite.
The standard certifies honesty of process, not quality of prediction. A forecaster of any skill may conform. What conformance guarantees is that the published record, whatever it shows, is complete and unaltered — and that anyone can check it.
