Scope & MVP Decisions

Implemented (MVP)

✅ General settings (registrations, maintenance) ✅ Security settings (login attempts, lockouts, sessions) ✅ Tab navigation ✅ Form validation ✅ Save/Reset functionality ✅ Loading states ✅ Error handling

Deferred (Phase 2)

❌ Email settings tab (SMTP config) ❌ Notification settings tab (channels, frequency) ❌ Maintenance settings tab (backups, cache) ❌ Analytics settings ❌ Integrations settings

Reason: Backend endpoints for email/notifications not implemented yet. General and Security tabs provide core MVP functionality.

Conclusion

✅ AdminSettingsPage is now functional for MVP

The page successfully transitions from "Under Construction" to a fully operational configuration interface. Administrators can now:

• Control user registrations
• Enable/disable maintenance mode
• Configure security policies (login attempts, lockouts, sessions)

The implementation is production-ready, with proper error handling, validation, and user feedback mechanisms in place.
