System Health shows every user's name and avatarAt to everyone, but the picture route GET /api/users/:id/avatar sat under the staff-only /users prefix, so a developer got 403 EADMIN and saw only initials. authGuard now lets any signed-in account make that one read (EVERYONE_READS); every other /users path stays staff-only, and the test checks both.
