The checksum checks internal consistency; it is not independent proof against database tampering. Results use the current corrected fixture record. The archived probabilities remain unchanged.
Multiclass Brier sums squared errors across all three outcomes (0–2). Log loss uses natural logarithms and a 1e-15 floor. Rounded probabilities are normalized for grading.
