Question

Which effects can cause a player (or encounter) deck to reshuffle in the middle of resolution? According to the rules, Draw does trigger a reshuffle mid effect, and Discard does not trigger a reshuffle. Per the Ultron’s Imperative ruling, a shuffle should be done to complete the effect. If instructed to Search, Look At, or otherwise interact with the top n cards of the deck, which cause a reshuffle to satisfy themselves, and which do not?

Answer

Your first statements were correct, that you can reshuffle and continue a Draw effect, but you would not continue a Discard effect after a reshuffle. And that Ultron’s Imperative requires two cards to be dealt, and a reshuffle can take place as this is resolving, because it’s not a “Discard” effect and it doesn’t adhere to the Discard rule.
Neither Search nor Look At effects would cause a deck to become empty, so neither should constitute a shuffling of the discard pile into a new deck. You would Search or Look At whatever area was specified by the card, resolving as much of the effect as possible.
