QA notes

Verify that, in a steady state, there are no non-inference type origins that have empty results in Octpoes/XTDB. This can be done using xtdb-cli.py or visually VisualOctopoesStudio.

To use xtdb-cli.py the following query checks for empty results for non-inference origins:
octopoes/tools/xtdb-cli.py query '{:query {:find [(pull ?var [*])] :where [[?var :type "Origin"]]}}}' | jq -C '.[][] | select(.origin_type != "inference" and (.result | length == 0))'

Jup works. Normalizers that yield empty observations after yielding observations with objects still nicely clean up their old data.
