You'll notice
Artifact titles now get carried into editor-renewal data and artifact metadata
What
When an artifact (a generated document, app, or other file Claude Code produces and can re-edit) has a title, that title is now included both in the data sent when renewing the artifact editor and in the artifact's metadata. One of these spots can also carry a favicon.
Why
This keeps an artifact's title attached to it through more of the editing and metadata handling, rather than dropping it in these paths.
