What Hari demonstrated

Built and verified a full legacy-service repair for KM-Wächter: fixed the wear calculation, handled missing service readings safely, corrected the nightly fleet report, added the missing regression test, and modernized the code style. Also produced a data-driven breakdown-risk analysis that followed the fleet_history.csv evidence rather than the misleading mileage assumption, and validated the result with pytest and the project acceptance script.
