What
When creating an artifact fails because Claude Code has no way to authenticate, some sessions now show "This session could not reach Artifacts: ..." instead of "Not authenticated, run /login". When Claude Code runs as a runner, creating an artifact also goes through a stricter relay route.
Why
In hosted sessions, telling you to run /login was not useful advice, so the new message describes the actual problem.
