The editor built the circuit-group subtree snapshot without
manualQuantity, while the server compares it with an exact capture that
includes the column. Deleting any group that contained a device row was
therefore rejected with "Circuit-group subtree changed before deletion."
The new integration test builds the snapshot from the real circuit-tree
read model, as the editor does, and deletes the group for a manual row
and for a row with a Revit quantity share.
