The Original Sin that sabotaged my citation graph workflow is that I used Redis as my data store, a data store that does everything in RAM. This killed scalability, disabled the service for years, and the only reason it came back is because I finally had a machine with enough RAM to run it. Currently I am working on a next-generation database in Postgres, and once I do this I may be able to rewrite Citationgraph Bot to use that instead.
