List	Version	Source flow	Name there	Why this flow
bafu	2026-v1	be168116-e9b8-5816-98ba-a6d5bb5eef29	Uranium Alpha	This substance answers to the name the row carries; both name the same compartment.
bafu	2026-v1	e68e7759-561f-5dbd-9ed6-a85994b0421e	Uranium Alpha	This substance answers to the name the row carries; no flow of this substance sat in that compartment, so this one was created for the row.
