Presence can show selected entities, active editors, editing fields, cursors, camera/viewport state, Prefab Mode locks, active uploads, and last-seen state. Selection outlines and camera/follow affordances are advisory; they help collaborators coordinate without locking ordinary edits.

Prefab Mode shows when someone else is editing a prefab. A collaborator can also use Lock Prefab during a major refactor; this is visible to everyone but still advisory.

Uploads show as shared progress while a collaborator reserves, uploads, finalizes, validates, completes, or fails an asset upload.

Private AI prompts do not appear in shared activity. Project-visible AI runs do.
