Is OpenTrustBench production-ready?

Legit.Show scores OpenTrustBench 57 out of 100 — the simple average of its 5 measured frames. Legit.Show ran its deterministic 7-Frame production-readiness benchmark on OpenTrustBench (public-surface assessment), measured from the public surface with no LLM in the scoring path. Its strongest frame is Discoverability; its weakest is Privacy. 5 of the seven frames returned a score; Performance and Accessibility were not measurable on this service and are recorded as null — not as zero.
