Women-only events
Any woman can create or join a women-only event. Gender is declared once during sign-up and is then permanently locked — it can't be edited in the app, and corrections go through support. We don't check it against a document, and we won't pretend we do. What we do enforce is the wall around the event: to everyone else it simply doesn't exist. Not in the feed, not on the map, not in search. The attendee list is closed off the same way, so nobody outside can see who's going, and a link to one shared publicly returns a 404.
