List Version Source flow Name there Why this flow
EF 3.1 fe0acd60-3ddc-11dd-a97e-0050c2490048 lead The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 f63c7822-ac27-5c6b-a036-8f89d9810450 Lead The CAS numbers are the same (7439-92-1); 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.

Something wrong here?

A flow can be wrong in three ways, and they are decided differently. Pick the one that matches what you are looking at.

You do not need to run a build or clone anything. Name the row and say what your evidence is; the measurement is done for you. How contributing works
