Feel free to try to trace a WabiSabi coinjoin yourself, no one else has been able to do it:

https://kycp.org/#/1ca4743bd12bc54cd19233f0807ae8b7faec7fdce695f72f345b99d0200ef3d5

15 address reuses
13 exit merges
233 inputs linked
236 outputs linked

This is exactly the sort of confusion a coinjoin is designed to cause Grin

You mistakenly thought that multiple inputs being spent together meant that they were linked to the same owner, but a coinjoin has inputs from multiple owners in the same transaction!

2 address reuses

This one with extra bonus of 100% deterministic link between input and output!

Here is the exit merge transaction spending coinjoin outputs - 9273410e2994fa02fb1baa071d84a44fb4ad12ceba50a46eadfd24cf0dd7efa6 - let's analyze the coinjoined inputs!

In the coinjoin, there are 13 outputs for 0.1 BTC:

By consolidating two inputs for 0.1 BTC for the payment, the owner retroactively reveals a coinjoin output value of 0.2 BTC. Does this cause him to lose any privacy? Let's check the original coinjoin transaction to find out...

In the coinjoin, there are are 9 outputs for 0.2 BTC:

This shows how the "smart clients" arrange their output values so that merging outputs together results in even more matches!
