  "reasoning": {
    "task_resistance": "Cutting out a cracked center sill and welding in a new section, pressing wheels onto axles, changing a Type E coupler knuckle in a yard track, and rigging a 100-ton car onto jacks are single-piece, non-repeating operations on equipment that never presents the same way twice — the only genuinely automatable slice is the AAR job-code paperwork, which is why this sits at 17 rather than mid-band.",
    "embodiment": "You work outdoors on ballast in whatever weather the yard gives you, crawl under cars behind blue-flag protection, torch and weld in confined body positions, and carry brake shoes, draft gear and slack adjusters by hand — the only thing keeping it off 20 is that some shop work happens indoors on a rip track with overhead cranes.",
    "liability_shield": "49 CFR 232 and 215 require you to be a designated qualified person to perform and certify Class I brake tests and single-car air brake tests, and your name on that record is what the FRA cites after a derailment — but the railroad or contract shop holds the certification program and the enforcement usually lands on the carrier, not on a personal state licence you could lose, which caps this at 12.",
    "trust_premium": "Car owners and yardmasters deal with your shop, not with you by name, though a mobile repair truck operator working the same shortline customers or the mechanic a trainmaster trusts to make a call on a hot car does build a real personal reputation — that's relationship value, not the product itself.",
    "judgment_accountability": "Deciding whether a car with a cracked sill or thin wheel flange gets a running repair, gets bad-ordered and shopped, or is safe to move empty to a repair point is a real call with derailment consequences, but AAR interchange rules, FRA condemning limits and wheel gauges give you hard numbers for most of it, which is why this is 12 and not 16."
  },
  "rationale": "The job is welding cracked sills, replacing couplers, wheelsets and brake shoes, jacking cars, and crawling under equipment in yards and repair-in-place tracks — physical work in weather, on uneven ballast, with heavy irregular components no current robot handles. AI can absorb the paperwork tier: defect coding, AAR billing repair cards, parts ordering, and increasingly automated wayside detectors that flag hot bearings and wheel impacts before a human looks. What survives is the FRA-qualified person actually certifying air brake tests and single-car tests, and deciding whether a car gets patched, shopped, or bad-ordered out of service.",
  "outlook": "Employment stays roughly flat and tied to rail freight volumes; predictive detectors will shift work from routine inspection walks toward targeted heavy repair, so the wrench-and-welder tier holds while the clipboard tier thins.",

        "change": "FRA tightening 49 CFR Part 215 / Part 232 qualification rules so that a named, individually-qualified inspector must personally certify Class I air brake tests and single-car tests, with the certification non-delegable to automated wayside or machine-vision inspection output — the reverse of current railroad petitions for waivers allowing automated track/car inspection (ATIP-style) to substitute for walking inspections. A rulemaking that explicitly bars automated inspection from satisfying the certifying-person requirement would raise this.",

    "ceiling_note": "No realistic route to a higher trust premium: the buyer is a railroad or leasing company optimizing car-hire cost, and no shipper pays extra for human-performed repairs. Embodiment is near ceiling already and cannot rise. Total headroom is roughly 8-10 points, concentrated in liability_shield, and it is contested — carriers are actively petitioning FRA in the opposite direction to substitute automated inspection for human walking inspections."
