Cleared source observations for the selected class. Per-round tables supply explicit timing, grids, laps and race points where available. Season matrices fill remaining races. Replaced matrices are retained as evidence, with genuine conflicts withheld. Combined classifications and interim standings remain separate; no missing field is reconstructed. Full coverage and certification remain incomplete.
