Why mam-main uses FastCron instead of wp-cron.php, how mam_setcron_manager schedules jobs through the FastCron REST API, and the AJAX endpoint mam_setcron_processor that pings on every tick.

How mam-main hands off iOS / Android builds to the WPMAM Fastlane CI: account-code verification, mam_fastlane_settings filter, the publish endpoint, and the fire-and-forget submit pattern.

How MAM_Account_Code_Manager owns the local-app-account_code option, the enrollment server handshake, the transient cache, and the graceful-degradation hooks for enrollment-server unreachability.

How forms-manager integrates with the third-party Gravity Forms plugin: GF discovery, the cache layer, the per-form-id submission hook chain, and what happens when GF is missing or deactivated.

How wp_mam_notifications_history records every dispatch, how the in-app notification center reads it, and the opt-out tables (per-user email opt-out, SMS STOP, push permission revocation).
