For background, we don't ever want to call
evaluate_added_goals_and_make_canonical_responseif a previous call totry_evaluate_added_goalshas bailed withNoSolution, since our nested goals are left in an undefined state at that point. This most commonly suggests a missingEvalCtxt::probe, but could also signify some other shenanigans like dropping aQueryResulton the floor without properly?'ing it.r? @lcnr
