What it requires. No active Process Builder processes or workflow-era automations should remain in the org. These surface through the Flow API with processType Workflow, CustomEvent, or InvocableProcess.
Why it matters. Process Builder and Workflow Rules are retired generations of automation, superseded by record-triggered flows. Legacy processes run in system context without sharing considerations, fragment an object's automation across tools, and block the one-entry-point model the decision guide prescribes.
How to fix it. Migrate the process to a record-triggered flow (the Migrate to Flow tool covers most patterns), then deactivate and remove the legacy version.
Is this rule worth checking?
