The Test Data I Did Not Write

Clean Architecture correctly positioned the database at the edge, yet erroneously grouped essential product knowledge there. A detailed order flow diagram illustrated services for creation, payment, inventory, cancellation, and refund, including queues and circuit breakers, while Analytics remained overlooked. Separately, a charging map displayed duplicate pins due to multiple data sources like Tesla and the German federal register. Despite a refactored nightly job with a passing test suite, data duplication persisted after fourteen months.
