The passive condition must exist when this resulting action is resolved in its own chain of effects, or the action is canceled. Note that actions in the strike sequence follow a different set of rules.
Annotation 9a: If a card is required to be discarded by some passive condition, the card is discarded immediately when the condition resolves, not in the following chain of effects.

If passive condition is produced not in chain of effects this action becomes automatically the first action declared in the new chain of effects. No chain of effects may be started before this chain of effects.

CoE Rules Digest #112 wrote:(4) The question has arisen how one is supposed to deal with sites that have effects in their card text, e.g. hero Mt Doom and minion Isles of the Dead that Live. This led us to a total formalization of the beginning of the movement-hazard phase.
--------------------------------------------------------------------------------
The beginning of a company's movement-hazard phase unfolds thus:
(A) Revealing the site: Simultaneously determine the company's site path and the base hazard limit. This happens immediately, and cannot be responded to.
* Opponent halving the hazard limit in order to sideboard affects the base hazard limit.
* There are special rules concerning Under-deeps movement. (CRF: Rulings by Term: Under-deeps)

(B) Resolution of the site: Simultaneously draw cards, resolve other effects of the site card, and apply any other relevant effects in play. This happens immediately, and cannot be responded to.
* Annotation 26 applies here, except for hazard limit modifying effects which were in play prior to the start of the movement/hazard phase.

(C) First chain of effects: Effects that were played during the organization phase and depend on the site or site path of a moving company, create an effect which is now declared along with actions from passive conditions.
* After all of these effects/actions have been declared, players are free to add to this chain of effects by playing cards and/or declaring more actions.
