Matchup lab
Build any matchup and score it with the same forward engine that prices the daily slate: pick the away and home team, then drag each side's schedule situation. Sliders prefill to each team's real rest state as of the last engine run; everything recomputes instantly in your browser.
Lab numbers are interactive hypotheticals — they are never logged and never enter the season accuracy tracker, which scores only the append-only pregame record. A rest of 0 means a back-to-back (played yesterday); rest is capped at the engine's 7-day ceiling. Cold-start teams score from the league-average prior. Each team's lineup-based ratings use the roster it dressed last game. Scoreline odds carry the engine's fitted adjustment for tied games, the same as the daily predictions.
