Structured contract copied for validation or lookup.
- Purpose
- Output contract: one ref per workflow input, resolved or an honest gap with a reason. Cast bundles the JSON Schema; validate with `foundry validate-test-data-refs` before returning.
- Verify
- Run the test-data-resolution chain on a pinned scenario and confirm each leg's test-data-refs.json validates and implement-galaxy-workflow-test stages from it.
