Why execute TIDY phase for HELD entities?

TIDY is always executed for all entities when a request fails. The system would not know in advance if there were any build materials for the entities. Thus, the TIDY phase is invoked. This is considered a good "just in case" mechanism to clean up any build materials left over or to determine if they should be kept for subsequent re-release which happens with interdependency.

TIDY is also valid for HELD entities when a request completes successfully. Assuming an interdependent request with entities A and B on first execution, the build for A could succeed but then the build for B fail. In that instance, the build materials for A would be retained. If the user then held entity A before resubmitting the request, the tidy phase needs to be executed in order to get rid of the retained build materials from the first submission.
