Does an artifact's 'whenever this card goes to your discard pile' effect trigger at end of turn?
One reply says so, and no designer post is among the sources.

Yes. The trigger covers every route to the discard pile: when the card is acquired, when it is discarded from hand, and when it moves from the play area to the discard pile at end of turn.
