No venue currently has this status. No badge for this appears anywhere on this site today, and none will appear automatically just because a venue is public.
An Attendant Guild Partner Venue would be somewhere whose staff are genuinely familiar with the Safe Exit procedure — confirmed directly with that venue, never assumed. It would never be called a "safe venue," and Attendant Guild would never claim a venue guarantees anyone's safety.
Where a venue has genuinely confirmed it supports Ask for Angela, that could be shown too — only where it's actually true, never by default.
That stays with Attendant Guild's own review process.
