Artemis II is not on the pad. It's in the VAB, and it isn't stacked yet (source: my sister's an engineer with NASA Exploration Ground Support and is one of the people in charge of assembling it).

There's a lot left to do before it's ready to launch: https://spaceflightnow.com/2025/10/17/orion-spacecraft-arriv...

Of course, compared to the decades-long SLS timeline, that's "ready to go".
