Model card. The DOC race formula is now fully recovered & runtime-validated (SH-4 static + live GDB trace, see _sh4/decode/*.md): weighted-sum accumulator, dirt 4-band curve, condition gates, linear late-falloff, the 12-key distance table @0x10F204 (a pace normalizer: distance×mult≈const; 1.0323 = 1600m), the stamina-drain ladder, and the whip/hold handler (grades 1/2/3).
This page now includes BOTH the transparent strength & best-trip estimator (aggregate, normalized 0–100) AND a faithful tick-by-tick simulator (the ▶ Run race / Odds buttons) ported from _sh4/sim, which integrates the per-tick velocity, stamina drain, and [10,160] clamp across the race from each horse's roster stats.
The sim runs at real-racing pace: average speed is held near-constant across distances (~9% sprint→stayer fade, matching real thoroughbreds), anchored to the measured 1600m turf time (winner 48.5s). The Realistic field mode uses DOC's grade + surface groupings in a competitive class band for game-like ~16s finishes.
faithful tick-by-tick sim — Realistic fields the race's grade + surface in a competitive class band (game-like ~16s spread); each Run reshuffles the field
