Source lists

in merge order

A source list carries one row per substance per context, so its rows are not its substances: flow objects counts the distinct names its rows use.

# List Version Rows Flow objects
0 ecoinvent 3.12 9,850 1,805
1 ecoinvent 3.8 4,421 1,389
2 bafu 2026-v1 2,679 1,003
3 stepwise 2006-1.09 6,055 1,370
4 agribalyse 3.2 5,485 1,778

Order matters: a later list can match a flow an earlier one created.

Outcomes

rows, and what they are

Flow objects counts the distinct substance names the rows carry; elementary flows counts the consensus flows they landed on, which is why unmatched has none. The last line counts every row once, so it is smaller than the columns added up.
