What Romesa demonstrated

Built and verified a full legacy-code modernization for a fleet service system: fixed the wear calculation so near-due cars are flagged correctly, handled missing service readings without false positives or crashes, corrected the nightly report’s averaging and mileage conversion, and added the missing regression test. Also produced a data-driven breakdown-risk analysis that follows the fleet history data rather than the naive mileage/age assumption, and documented the review process clearly in NOTES.md.
