The Action framework needs to have a method for running all of the Actions in dependency which is called from main.py. When called, the function needs to:

• Generate a list of all the Actions on the system
• Consult the dependencies of each Action to run them in a set order.
• Fail if there are Actions with unsatisfied dependencies. This should be such that we fail prior to shipping a release.
• Run the Action in dependency order, recording success or failure.
• Record any Actions whose dependencies have failed as Not Run due to whichever dependencies failed and skip them.
• Hand the record of success and failure to another subsystem which will emit a report.
• If there were any failures, stop the conversion. Otherwise, return to main for the next step (for pre-assessment, rollback and exit. For conversion, prompting the user to continue to post-PONR tasks).
