How does this interact with the concept of an "attached wallet"?
User A and User B both have direct private channels to SN with plenty of liquidity both ways. They have no other channels. They both have attached wallets.
Are they able to zap each other directly through SN?

Yes, because SN proxies the invoice. The sender pushes money to SN (SN can't yet settle it without a "cryptographic proof" it only gets when the receiver is paid), SN pays the receiver, then SN settles with the sender.
Both the sender and receiver only need to know about SN and be able to route to/from. Neither lightning node knows who the other node is.

Are you worried this makes SN a money transmittal organization? 😵‍💫

we're moving towards this to not be a money transmitter

This is what every lightning routing node does.
SN never has custody which, to date at least, has been what determines whether an entity is a money transmitter.

I see.... there is still much I need to learn about the details of how lightning works.
