Authors save the intended record and submit the current revision to the existing editorial process. Publication preserves audience and eligibility rules. Engineering's maintained handbook is packaged from source; its CMS articles remain editorial records and are not overwritten at startup.
The page builder now includes immutable checkpoints, previews, exact-revision releases, explicit menus, discovery and guarded images. Home/Site Guide conversion has explicit route modes and recovery. Authoring and public serving are separate switches; implemented source does not imply a live public rollout.
Video publication requires substantive description, eligible cast and valid linked lyric context. Discovery, current-release evidence and content removal retain their owning filters. Retention reports do not by themselves authorize deletion.
