Case
- Goal
- Measure CommonJS loading and transformSync availability for @babel/core 7.29.7 from an ES module HOW
- Packages
-
@babel/core 7.29.7
- Environment
- node

Commonly assumed
Loading @babel/core through createRequire from an ES module throws instead of returning the CommonJS API object.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- assert createRequire can load @babel/core 7.29.7 from the ES module contract
- assert the loaded API exposes transformSync as a function
- assert transformSync returns an object whose code string contains the transformed const declaration
