List	Version	Source flow	Name there	Why this flow
EF	3.1	653d74e8-d259-4d3d-81b3-4f47c391fd51	mercury (ii)	The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu	2026-v1	4a154714-6351-5214-911b-86f0b14651cb	Mercury	The CAS numbers are the same (14302-87-5); both name the same compartment.

Every implementation that says anything about this flow. Published as is what this list did with the row: where more than one implementation states a number and they agree it publishes it as agreed; where only one speaks, as sole; where they disagree it publishes nothing and asks.
