What we fail, and why

L3-09fail

UCP readiness

We do not sell products, so there is no catalogue to expose. The check runs anyway rather than being silently excluded, because a rubric you can opt out of is a rubric nobody can compare against.

L3-10fail

x402 payment support

No agent-payable endpoints yet. On the roadmap for the API, not for the marketing site.

L2-18partial

Content freshness

Four Registry pages have not changed in over 60 days. Flagged against our own 30/60/90-day thresholds, same as any client.
