What the checks measure
The contract, automated
Every check traces back to a specific token or rule in the design system contract. Motion standards, typography cadence, color discipline, accessibility thresholds, and identity rules — all codified, all verifiable. The score is the output metric: not whether you read the contract, but whether your design actually passes it.
