Built a working modernization of the KM-Waechter service flow: corrected the wear calculation, handled missing service readings safely, fixed the nightly report’s crash and mileage conversion bug, and added the missing regression test. The candidate also documented what the AI agent got wrong and verified the result with the project’s acceptance script.

What stood out6
- Fixed the nearly-worn-car bug with true division so 14,900/15,000 now evaluates to about 99% instead of 0%
- Caught and corrected the quiet helper-module mileage conversion bug that no test directly covered
- Added the missing report test for a car with no last_service_km and documented the verification steps in NOTES.md
- Leakage-Free Bug Diagnosis
- Directed AI Code Review
- Acceptance-Driven Verification
