especially in this case where trelix lets you perform an attack in the standard rear arc, ignoring the "[front arc] attack arc"-restriction.
See this is where you are wrong. the YV-666 cannot use outmanoeuvre on it's primary weapon as it simply cannot perform [Front Arc] attacks with it, the arc you actually use for the attack it irrelevant, only the arc printed on the weapon.
