So with a card like "Lookout Post" from twenty festivals, it has an absent interrupt with the following wording, " Negate the action if it is Engage", this would negate cavalry because the movement from it would be the action correct? But would this stop Naval? because there's no actual action from announcing Naval as an engage, or would it stop the battle action allowed because of Naval?
Negating engage for naval/cav/etc
A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing.

It will negate Cavalry which is a player Engage ability.
It will also negate Naval, which is also a player Engage ability. Negating Naval does not negate the Battle action that would've been taken prior to the defender's first opportunity for a battle action, as happened with cards in the past such as Reinforce the Gates and Entrenched Position; it simply negates the action that would give the attacker the opportunity to take the first Battle action.
