Model Validation
NFL performance desk
NFL proof starts in shadow.
One complete, timestamped player-prop checkpoint is useful evidence. It is not an official record and it is not enough to establish long-run profitability.
Official record
Nothing to headline yet.
Forward shadow checkpoint
A profitable test, with limits attached.
Test #001 is preserved in full. The pregame checkpoint, every winning and losing row, captured price, actual result, injury context, and correlation warning remain visible in the master proof ledger.
What comes next?
Repeat the process across independent slates.
Forward checkpoints need broader game, market, price, and week coverage. Official grades and units stay unissued until the calibration threshold is satisfied.
