What
When publishing to an existing artifact slug (its short name), and no contract was supplied, Claude Code can now fetch the artifact's type and contract again before publishing, using the capabilities it already knows about. This only happens when the publish mode allows it.
Why
The publish step works from the artifact's current type rules rather than a missing or outdated copy.
