Method
Three steps, in order. Skipping any one of them breaks the record.
A model produces a probability and a stake size before an event starts. Nothing here is a human's after-the-fact opinion.
The prediction is signed, hashed, and chained to the row before it, then timestamped — before the event, not after.
Once the event ends and a verifiable market close exists, the prediction is graded against it. No close, no grade.

FAQ
No. The predictions table is append-only at the database level — the server itself has no UPDATE or DELETE privilege on it, regardless of who's asking.
It's marked ungraded and stays out of the public record. Brier doesn't grade on an assumption.
Grading is only as honest as the closing-line data behind it. One market, done right, beats several done loosely.
