wdyt about also adding changes to the enriched_history_operations SQL? I think Securrency still uses that table as a source.

Also do you mind sneaking in a change to disable relevant asset trades? This would snooze the data quality alerts we're getting due to the bad SCD 2 # table

I don't think we should. I would rather them point to the new dbt eho table.

Yeah I can add that
