FLX-7001: observed readout predates its registered prediction
Family: calibration (the 7000 band)
A PredictionRecord is sealed by its registered_at instant; an ObservedReadout naming an observed_at before that instant could only have been known before the prediction was made, which makes it evidence for the prediction rather than a test of it. Register the prediction before the outcome window opens, or read the outcome again once it has.
