They do, however, both trust me.

Calle can lock his payment token to all three of us, requiring 2-of-3 signatures to redeem... and specify a time limit for performance.

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.

Trust is an unavoidable part of all lightning/layer2/custodial solutions. The answer is you need to pick your mint carefully… same as you choose your lightning wallet provider.

I’d add that I don’t even trust myself not to leave cash in my pockets of my jeans that go in the washing machine.

Well, a better analogy would be whether you trust that Visa will give your money to the marchant each time you pay for something or just take the amount from you, pocket it, and leave you in an awkward position.

EVEN IF YOU USED AN INTERMEDIARY to mitigate the risk, only to learn that the intermediary had no power to begin with.

Honestly, for the equivalent of a few small bills in the pockets of my jeans, if I worried about it a good deal then that'd mean (a) I'm really struggling financially, in which case I've got bigger things to worry about, or (b) I've got some kind of OCD, so again, bigger things to worry about.
