Module settings 

DRE’s settings and where each value came from.

A setting is chosen, highest first, by its command-line flag, its DRE_* environment variable, its key in dre_project.yml, then its default. [env] is the one place DRE reads its own environment variables; Settings records every resolved value with its source, for dre validate --verbose (and its JSON), run_results.json and the run’s log.
