Welcome to the Official Redemption® Message Board!
Removing the last character on either side of the battle doesn't force the battle into battle resolution. The 3rd part of the battle phase (initiative) isn't fully described, because you can trigger other cards (like Writ or Unknown Nation) there as well, even after one side is completely removed. You don't enter Battle Resolution until both players agree to it (more or less).d-2 is about characters that are defeated by the numbers.
I had this situation in a recent tournament where I discarded my opponent's last EC, was now unblocked, and had a sole rescuing hero. He threw down CM. I didn't think this could be done, but because I was unfamiliar with the rules at the time and didn't challenge it, I went with it. When this situation occurs, a dominant like CM should not be able to be played since my opponent had plenty of time to play that during battle but didn't.

What you are missing is that the battle did not end when you discarded his EC. Your opponent is allowed to respond to your action with his own dominant before Battle Resolution begins. Whether he "had plenty of time to play it" earlier or not is irrelevant.
The REG is intended to be an "advanced guide". Everything that you need to play and enjoy the game is in the rulebook, but for tournament play where minor issues can mean a difference between winning or losing the tournament, a more in depth guide is needed. Which is where the REG comes in. It doesn't have step by step rules as to how you would go about playing the game. So if you are looking for how to play a particular part of the game, it might be better to look in the rulebook, then verify that the REG doesn't contradict it. For looking up how a certain ability should be played, the REG is usually better. But the rulebook is still valid, and looking there for understanding the game is perfectly fine, as long as it's not contradicted by the REG. And yes, you are correct. Battle resolution happens when both players agree the battle is over.
