+
+	- No join to the element table. A terminal row already carries its
+	  element_uuid, so joining element back just to read the same uuid adds
+	  nothing -- and would actively drop rows, because populateElementTable()
+	  only inserts elements matching Simple|Terminal|Master|Thumbnail. Slave
+	  elements (relay contacts and the like, extremely common at the end of a

+	  load, so an inner join through it silently loses their conductors.
+	- element_info is LEFT joined for the same reason. A wire whose endpoint
+	  element carries no info row still belongs in a wiring list; it comes
+	  back with an empty label rather than vanishing. Losing a wire from a
+	  wiring list is a worse failure than showing one with a blank end.
+
+	- diagram is LEFT joined for the same reason. It should
+	  always match, since QETProject::diagramAdded is wired to addDiagram()
+	  and a conductor cannot exist before its folio -- but an inner join here
+	  would make that an assumption the view silently enforces, and a wire
+	  missing from a wiring list is the one failure this view must not have.
+
+	The result is that this view returns exactly as many rows as the
+	conductor table holds -- what is already excluded upstream (conductors
+	on legacy terminals without uuids) stays excluded, and nothing new is
