What

The check that runs before an artifact bundle is published now also refuses bundles containing <!-- frame-runtime --> and <!-- /frame-runtime --> markers, joining the existing refusals for mermaid and chart-runtime markers.

Details
  • Rejection message: bundle contains a frame-runtime serve sentinel.
Evidence

bundle contains a frame-runtime serve sentinel

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