farmer maggot

Playing a card is the process of bringing a card from your hand into play.

A card isn't in play until it resolves.

Cards that tap the site as an active condition require an untapped site as part of that active condition.

Cards that tap the site as an effect once they resolve require (by rule) an untapped site.

The both require the same thing, but for different reasons, and tap the site at different points.

The phrase "such an attack can occur only if one of the following criteria is met" seems to me to apply to any attack generated by a creature card.

Attacks generated by other sources (such as Dragons Ahunt) are considered hazard creature attacks, but are not generated by a hazard creature card.

Cards that tap the site as an active condition require an untapped site as part of that active condition.

I would say (according to CRF) that:

Annotation 5: If an action requires an entity to tap as a condition for the action's main effect, that entity must be untapped when the action is declared; else, the action may not be declared.

"Tap X" and "X must be unapped" are mutually exclusive active conditions. Second is prerequisite for first.

Attacks generated by other sources (such as Dragons Ahunt) are considered hazard creature attacks, but are not generated by a hazard creature card.

Ok. However Dragon Ahunt does not create immediate attack. Non-creature cards that creates immediate attack are e.g. cards allowing Agents to attack during m/h phase.

are we still discussing about the relation between assassin and farmer maggot?

Now we are discussing about assumptions, which are base of such or another interpretation of Such an attack can occur only if one of the following criteria is met.
