What

The artifact publish helper takes a single options bag instead of positional flags, and reports one more field on success.

Details
  • Options are injectDiagramRuntime, injectHighlightRuntime and composedPrReview.
  • Successful validation can attach refusedClassSidecarTypes to the result.
  • Content-type detection for uploaded files moved from an inline extension map to a helper.
Evidence

injectDiagramRuntime

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
