Players are verified when they're in the configured Steam group (public memberslistxml, refetched every 10 minutes, kept on failure) or have an unexpired override row in gv_verified, written by the web panel. Settings and data live in CS2-SimpleAdmin's MySQL database (gv_verified, gv_settings, gv_migrations), reached through its API. - css_gv_group <groupId64|0>, css_gv_enable, css_gv_disable (@css/root): verification runs only when enabled with a group set. - css_verify <target>: why a player is or isn't verified. Admin and above (by immunity from SimpleAdmin's groups) plus Guardian, unless admin_overrides.json says otherwise. - groupverify:api (shared/GroupVerifyApi): IsVerified, GetStatus, IsActive and OnVerifiedChanged. The API object lives in the shared assembly, so it survives hot reloads of GroupVerify.
