Races come from Tyre Signal's own scenario generator (season-scenarios-v1): seven race states (green, traffic, safety car, VSC, restart, wet, damage) with the project's transition odds and pace penalties, its fuel coefficients, an RBF nuisance process and Student-t lap noise; both strategies share every draw. The tyre curves and pit losses (22 s, 11 under a safety car, 14 under a VSC) are illustrative: the fitted curves come from archived timing data that is not in the public repository. A simulator, not a forecast. Circuit outlines: bacinger/f1-circuits (MIT).
