🎮 Try in WordPress Playground

Open this PR in Playground →

Preview is pinned to WordPress 7.0.

Uses the checked-in blueprint.json from this PR, with the plugin install pinned to commit d89f004094965dcf2f8766e65e2033a3ce95b590 through Playground's CORS-safe git:directory resource.

Logs in as admin / password; use password again for the WP Sudo reauthentication challenge.

✅ What you can test

Feature	Notes
Plugin activation & settings page	✅
Gate fires on dangerous actions (plugin activate/delete, user delete, etc.)	✅
Challenge / reauthentication page	✅
Password verification & session cookie	✅
Admin bar countdown timer	✅
Request stash & replay after auth	✅
Rate limiting / 5-attempt lockout	✅ within session
Session expiry by time	✅ wait out the configured duration (1–15 min)
Two Factor plugin (TOTP)	✅ installed automatically via blueprint
unfiltered_html removed from Editor role	✅

❌ What won't work

Feature	Why
WP-CLI / Cron entry point policies	No CLI in browser
REST / XML-RPC entry point policies	Network disabled in Playground
Two Factor email / magic-link providers	PHP outbound network is off
Multisite behaviour	Single-site only
State after refreshing Playground	Full reset on page reload

Transients and user meta persist across normal WP navigation within
a session, but are wiped if you reload the Playground page itself.
Use the integration test suite to verify
transient TTL, real bcrypt, and multisite isolation.
