Artifact comments and messages now carry an optional presence field for human authors

What

Comments and messages attached to artifacts (files Claude creates or edits that you can view and comment on) now include an optional presence field. It is only filled in when the comment or message comes from a human, not from Claude.

Why

The finding does not say what the field displays or how it is used, only that it exists and is populated for human-authored comments.

Confirmed since Anthropic's documentation has since written up presence, on Beta. the presence of this entry in `usage.iterations`. api/beta see the edit
