Forum:Cost as last resolved event

Can costs of activation be considered the last resolved events in a game? For example, assume that my opponent has a face down Trap Hole, and I summon a monster with more the 1000 ATK. Since I am the turn player, I have priority to activate a card or effect immediately after the summon, so I could activate something like Smashing Ground and then priority would pass to my opponent, who could then chain his Trap Hole to my Smashing Ground since my monster's summon is still the last resolved event in the game (ergo my opponent's Trap Hole has not missed the timing). But what if instead I were to activate something like Lightning Vortex, which has a discard cost? Would the discarding of a card become the last resolved event in the game, meaning my opponent would miss the timing for Trap Hole?

Also, if that is not the case, when is the discard (or any other cost) considered to have happened? At some point in the game, costs must be considered to be resolved events, otherwise cards like.....Dandylion.....would never activate their effects after a chain resolves (in which they were discarded as a cost and successfully landed in the graveyard).

Actual quotes or rulings from Konami, citations from official tournaments, etc... would be greatly appreciated.
