What a person said should happen to a deleted run's results.
A run that produced nothing is never asked. A run that did is, once, when it goes into the trash - and the answer waits there with it, because trashing changes nothing in the artifact store and emptying the trash is what acts.
Keep is the default and the safe one. A run with no answer recorded keeps what it produced: a build that predates the question, a recording that was lost, a run that arrived by sync. Nothing infers delete.
