- Add OrderBookDomain: in-memory order book with Pending →
WaitingForPayment → Fulfilling → Delivered state machine, payment
window based on passed-in timestamps, cancellation rules
- Add OrderBookTests: 7 integration tests in given/when/then/when/then
anti-pattern style as starting material for the exercise
- Learning hour: add round 2 where participants create the example
themselves before showing it to the agent (no refactored test given)
- Fix sln: OrderTests Debug config was mapped to Release
Exercise project with Order domain and NUnit tests demonstrating
the 'show, don't tell' pattern for guiding coding agents.
