I may not be as technically sophisticated as many here, but I don't see how we can ensure that's not the case.
It uses something known as a Chaumian coordinator (as does Wasabi). Each participant in the coinjoin connects to the coordinator via Tor, and supplies the coordinator with their inputs as well as their blinded outputs. The coordinator signs these blinded outputs and returns them to the participants. The participants then unblind their outputs and reconnect to the coordinator via a new identity, and then send back the now unblinded outputs. The coordinator can still verify these unblinded outputs are correct since they still carry the correct signature the coordinator gave them earlier. The coordinator now has all the inputs and all the outputs, but cannot match them up.

It would obviously be possible to introduce a vulnerability in this process, but given that both wallets are open source, any vulnerability should get picked up and revealed.

Bitcoin is fungible with or without you, and you're not helping it's fungibility at all.  Quite the contrary, your shenanigans can only hurt.
Call me crazy, but here's an idea to promote bitcoin fungibility: Don't user coinjoin fees to directly fund blockchain analysis firms.
