Questions to ask at workshop:

Ask a REF person:
- How does the REF deal with supplementary variables?

Ask tech lead people:
- How do we get variables and datasets from a recipe?

The issue names no file, test, or entry point. Start by confirming the two questions with the relevant REF and technical-lead contacts, then identify the workshop notes or documentation where answers should be recorded; done means both questions have clear, agreed answers in the appropriate materials.
