Problem
Pick sites show picks without a record.
A board that shows a model probability next to a market line means nothing unless the reader can also see how the model has done. Picks without a graded record are opinions.
Decision
One normalizer over four databases, with guardrails that null profit claims and freeze pregame odds.
Each sport’s back end writes probabilities to its own database; one normalizer reads them through a single contract and publishes graded results per sport. Edge, expected value and ROI are null on every public route until audited; the odds shown are a pregame snapshot, and at kickoff the displayed line becomes the closing snapshot.
Result
Four sports graded in public, with the record dated.
