How to Use Coven to Restrain Outputs

The ASP is kind of man helping man helping me manage that shared UTXO. But we're using coven as to sort of restrain the outputs. It's like a silent payment style. We anchor or coins, like two coins as we coin select it, into the coin join transaction, using ATLCs. And this is based on the public key, like, you know the public key after intended recipient already. So in order for the ATLC to be claimed by the service provider, the Coin Join Transaction ID has to exist. If there is a double spent pair of coins, I can't claim them because they are not mine.
