You'll notice
Artifact publish failures are now shown directly in the publish panel with the reason
What
When publishing an artifact's files fails, Claude Code's publish status panel now shows a red "Couldn't publish its files" message along with the specific reason, instead of failing silently or less visibly. Session state also now tracks crashedPublishChecks and frozenHotUpdate.
Why
This makes publish failures visible where you're already looking, so you know immediately that publishing didn't succeed and why, rather than only discovering it later.
