Is Systems Check production-ready?

Legit.Show scores Systems Check 92 out of 100 — the simple average of its 7 measured frames. Legit.Show ran its deterministic 7-Frame production-readiness benchmark on Systems Check (public-surface assessment), measured from the public surface with no LLM in the scoring path. Its strongest frame is Accessibility; its weakest is Discoverability. Every frame it averages is published with its evidence on the Legit.Show listing.
