Prod had 331 relationships, 268 computers, 204 machines, but the report came
back empty. The query only matched computer(source) -> machine(target), while
the import stores the general machinerelationships as machine(source) ->
PC(target) (only the synthetic measuring-tool links are PC -> tool). So the real
shop-floor edges never matched.
Make the query direction-agnostic (UNION of both orientations); a PC-runs-machine
report is conceptually undirected. Also drop the comtypeid=1 filter so the IP is
taken from the primary communication regardless of its type.
Test: a machine(source) -> PC(target) edge now appears in the report.
