mam_codex_manager — the settings inspection / discovery API. Lets admin tooling enumerate all registered settings, categories, and content-class field schemas without parsing PHP source.

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.

Per-phase reference for phase_auth, phase_settings, phase_content, phase_finalize. What each does, what each fires, what each reads/writes on the context, and where sibling-plugin hooks land.

How JSON_Cursor_Manager lets the mobile app fetch only changed sections. Per-section timestamps, the ?cursor= request parameter, when reset_cursor() is called, and the bypass_caching flag for cloning admins.
