According to the [Salesforce documentation], the best place to look for all automation rules and engagement studio programs that a prospect has been a member of is the Prospect's Audits tab. This tab shows a detailed history of all the actions and activities that have occurred for a prospect, including the automation rules and engagement studio programs that they have been added to, removed from, or completed. The Automation settings, Scoring rules, and Lifecycle report do not provide this information, as they are related to the configuration, scoring, and reporting of the automation and engagement features, not the individual prospect's history.
