How it's measured

ComputeSDK re-runs the sandbox suite every day in public GitHub CI and commits the raw per-iteration results to an open repo. We read those results straight from the source and aggregate the medians shown here — the composite is ComputeSDK's own headline score, folding reliability into the latency percentiles so a degenerate run can't top the board.
