What
Claude Code emits two new events around prototype artifacts: one when a prototype run starts, and one when a prototype is published, carrying the artifact's slug and whether it was the first publish.
Details
The publish event records artifact_slug and is_first_publish.
Neither event name exists in the previous build.
The functions that emit these events are new; which artifact flow calls them was not traced, so it is not clear from the build itself which user actions trigger them.
Evidence
prototype_publish
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
