What

The schema that defines the artifact tool's parameters was rewritten and now documents several new pieces:

  • read_page_data, an action that validates a page's declared data against a named interaction schema
  • a reserved preflight.js file convention at the artifact root
  • capabilities and contract fields for declaring what an artifact can do at runtime
  • type_query, type, type_url, and auto_open fields for browsing and creating artifacts from published "types"
  • a label field for named publishes
Why

This expands what an artifact can declare about itself and how it can be validated, browsed, and published, building on the previously introduced preflight.js hook and republish-deadline mechanism.
