What

Metadata attached to collaboratively-edited artifacts and documents, which already included cowritten, agentDirect, and typeLocked, now also carries a writerClass field. It is derived from whether the caller has an owner or writer permission role, and is used to decide whether a write applies to a single page or to the whole document.

Why

This lets the system scope collaborative edits differently depending on the editor's role, so an owner and a writer may not always have the same write scope on a shared artifact.
