✓
tier 2

We fetched the site and tested each signal ourselves. Dated, repeatable, re-checked on a schedule.

1 check did not pass when we last looked: API catalog. Each is a small, specific fix; the rubric says exactly what we look for.

Behavioural verification — an agent completing your key actions end to end, with the date published here — opens to a small founding cohort first. Leave an email to be in it.
