Recap and Feedback
We have followed a request through validation, application rules, and PostgreSQL. The smaller examples let us inspect each boundary. The marketplace combined them into draft editing, bidding, and repeat-safe auction closing.
Choose one accepted operation and one rejected operation in your project. Follow each from its input to the stored result. Which decision required current data? Which writes had to succeed together? What did your tests observe?
A transaction groups related writes. A coordinating lock protects decisions made from changing state, and a clock sampled after that lock makes deadline rules testable.
