Is Sim production-ready?

Legit.Show scores Sim 92 out of 100 — the simple average of its 6 measured frames. Legit.Show ran its deterministic 7-Frame production-readiness benchmark on Sim (public-surface assessment), measured from the public surface with no LLM in the scoring path. Its strongest frame is Privacy; its weakest is Security. 6 of the seven frames returned a score; Accessibility was not measurable on this service and is recorded as null — not as zero. Every frame it averages is published with its evidence on the Legit.Show listing.
