Artifacts now distinguish co-written content from type-derived content for consent purposes.
Consent handling for artifacts now distinguishes content co-written by a non-owner from content whose files or assets derive from an artifact type the user didn't author. Reading such content throws a distinct refusal unless consent was granted, with messages like "a co-writer has published to this artifact" and "[ownership: yours, co-written: a non-owner has also published to it]".
