This ledger is append-only: nothing in it is ever edited or removed. Predictions from 2026 are written before their game kicks off and carry the UTC timestamp at which they locked. The 2024 and 2025 seasons are archived model results, generated with that season's data and not locked pregame. Scores shown are the model's projected final scores, not results. Machine-readable: JSON · CSV. Player-level projections are withheld until they are verified against the current season's roster feed.
