Fidelity matrix
The behavioral cross-check runs the same probe corpus under the mock engine and under real React Native — and CI runs it against every supported React Native version in the Vitest × RN matrix. This page is generated from that matrix's own reports, so every number below was produced by CI, not written by hand.
Every probe matches on every gated React Native version.
