What Jevin demonstrated

Built a working modernization of the KM-Waechter service end to end: fixed the wear calculation so nearly-worn cars are flagged, handled missing service readings without crashing the report, corrected the fleet-distance conversion, and added the missing regression test. They also produced a data-driven breakdown-risk analysis that follows the actual signals in the fleet history data and documented the verification process clearly.
