Eleven statistical operations against a live 100,000-row dataset. The substrate returns a result plus the actual elapsed milliseconds — usually under 3.
Each button POSTs to /api/maths-demo/compute with one op. The substrate computes against a pre-loaded 100k-row dataset and returns the value plus the elapsed time it took.
Most engines need to materialise rows before a statistic can be computed. Validiti doesn't. Every result above came back signed and reproducible across the full 100,000-row dataset in single-digit milliseconds — the same shape Maths uses on a billion rows on the same commodity hardware.
