* CI min, recoverable min and failure rate cover only the latest 500 runs of a repo with more in 30 days.
Public data from each repo's GitHub Actions. Minutes are wall-clock workflow time over 30 days. These repos run Actions free (public repos always do). Each scorecard shows the private-repo dollar equivalent as a labeled estimate. Repo owners can remove their scorecard any time.
