They do, however, both trust me.

The token can be sent up front, and all parties can see the lock using Cashu Witness.

If the deal goes through, I can witness the token and send it on to HeidE, who can then sign and swap it for an unlocked token she can spend (again using Cashu Witness).

If the deal falls through, I witness the token and send it back to Calle to cash in.

if I get hit by a bus or the deal isn't done in time, Calle can cash in the token when the the token lock expires.

We have a proposal for cashu DLCs which I implemented for nutshell, so you could have an ecash DLC between calle and heidE without any intermediary and the Mint would be oblivious to the specifics of the wager.

Cool - Calle and HeidE could also do a 2 party token, 2-of-2 to sign... with no intermediary....

The party who can cash it in is the one who witnesses last.

That was my main compalint about current p2pk, you're relying on the mint to enforce

You still do… my NutLock tool only selects mints that are NUT-11 compliant
