Dataset boundary

No synthetic dataset — by design

A scan cannot be honestly stood in for by a file of invented numbers, and every tabular stand-in we sketched for this task drifted towards describing individual patients rather than groups.

Why we stopped

We do not invent person-level records where a stand-in could normalise unsafe or unauthorised decisions.

What responsible work needs instead

Anyone taking this further needs a partner radiology service and access to a real imaging archive under formal clinical-research governance, with a named sponsor, ethics approval, and reporting clinicians involved from the start.
