**Definition of Done**
https://github.com/bcgov/wps/wiki/Definition-of-Done

The issue names no files, tests, or entry points. First clarify which forecast model metadata must be retained, where submitted forecast values are stored, and how skill scores should be calculated before locating the relevant application components; done should include agreed acceptance criteria and tests for both behaviors.
