- * Reject JavaScript expressions in Cordis Loader entry metadata.

  * The Loader interpolates only a plugin entry's `config`; expression objects in
  * fields such as `disabled` remain truthy data and silently change composition.
+ * Example configs run from built packages, so every named package must resolve
+ * from the examples workspace and every local package must be in the root
