So, if I'm reading that correctly... the "good faith rule" should prevent abuse of actions vs. negation at announcement, however, the "good faith rule" apparently does not apply to attaching cards in the effect that you do not need to site any attachment, only an action that attaches something, and the target, (and any other additional costs caused by effect or as part of the specific action)?
If an action card, being face-down in your hand, is announced, and the action is negated, do costs still need to be paid?
Is paying for an attachment a cost of an action, or an effect? Or a cost of an effect?
For the "Good Faith" rule. If the sited action is on a card that is face down, is the card revealed or shown at all?
Is a Variable Gold Cost, such as with Hired Killer or Ruthless Advance, needed to be announced as part of the "Good Faith Rule"?
Is a Variable Gold Cost that does not affect targeting, such as Dark Fate, needed to be announced as part of the "Good Faith Rule"?
Would an action card with a variable gold cost of either of the two above mentioned types, that is negated by Reinforce the Gates, need to have it's costs paid?
Actual answers please, sending links to the CR or quoting the rulebook, while occasionally very useful (and the same thing) is often not specific or clear enough.

Every Samurai card I could find only negates effects of an action, not an entire action. If only the effects are negated (ie Reinforce the Gates), costs still need to be paid.

Its the cost of the attachment.

Face up.
http://rules.l5r.com/Card_types#Using_Action_cards A. The player puts the Action card face-up in a resolution area, which is created for that card.
B. The player announces which ability on the card is to be used. The action then proceeds (see Actions and abilities.)
http://rules.l5r.com/Abilities_and_acti ... _abilities At this step, the player says which ability he or she is using, indicating its source and, if that source has multiple abilities appropriate for that point in time, which ability is being used.
Good Faith Rule: When an action is announced, the player must be able to target all required targets, meet all conditions of the action, and pay all mandatory costs, to the best of his or her knowledge. (rest of section)
Is a Variable Gold Cost, such as with Hired Killer or Ruthless Advance, needed to be announced as part of the "Good Faith Rule"?
That is determined based on targeting and has nothing to do with ability announcement. The Good Faith rule still applies to the resulting cost.
Is a Variable Gold Cost that does not affect targeting, such as Dark Fate, needed to be announced as part of the "Good Faith Rule"?
Not sure if any such cards exist in the Samurai environment, but Dark Fate is paid during the Costs step of the action, and does not need to be announced during ability announcement. The Good Faith rule still applies to the minimum gold cost of 2 on Dark Fate.
Would an action card with a variable gold cost of either of the two above mentioned types, that is negated by Reinforce the Gates, need to have it's costs paid?
Hired Killer/Ruthless Advance would need to be paid based on targeting, as Reinforce only negates effects of the action. Dark Fate would need to have at least 2 gold paid per its costs, but you do not need to choose to pay more.
