    "task_resistance": "String-up after a break, feeling denier by hand at the godet, and judging when a bushing is drifting are still manual on most lines — but setpoint recipes, closed-loop tension and temperature control, and automated doffing on newer spinning positions have already absorbed a large share of the shift, which is why this sits at 11 rather than up with millwrights.",
    "embodiment": "You work within arm's reach of 250-300°C melt, glass bushings at bushing temperature, and steam-hot quench air, threading filament bundles by hand at the winder and hauling packages — an uncontrolled, hot, moving environment that no arm has been cheaply retrofitted into, held below the high teens only because the work happens on a fixed line rather than roaming a site.",
    "liability_shield": "No state license, no certification requirement, no signed record follows you; OSHA lockout/tagout and PPE rules bind the employer, and any fiber defect claim lands on the plant's quality system, not your name — the 2 reflects only that you may hold in-house forklift or confined-space cards.",
    "trust_premium": "The output is packages of yarn or roving graded by denier, tenacity, and break count; the customer never learns which operator ran the position, and shift handover to another operator changes nothing about the product.",
    "judgment_accountability": "Your calls are bounded by the recipe sheet and control limits — bump the winder speed, pull a position, escalate to the process engineer — so real discretion exists on when to down a position mid-shift, but the draw ratio and temperature profile were decided by someone else."
  },
  "rationale": "The work is hands-on: threading filaments through spinnerets, changing dies and bushings, clearing broken ends, doffing packages, and adjusting temperature, draw ratio, and winder speed on continuous fiber lines. Language AI barely touches this, but the plant-floor automation that already runs modern spinning lines does — inline vision inspection, closed-loop process control, and automated doffing steadily cut the operator-to-machine ratio. There is no license, no signature, and no customer relationship protecting the role; what protects it is the awkward physical reality of hot polymer, glass bushings, and thousands of fragile filaments.",
  "outlook": "Employment keeps shrinking as fiber lines run with fewer, more technical operators; the survivors are the ones doing changeovers, mechanical fixes, and break diagnosis rather than watching gauges.",

Watch for the operator-to-machine ratio falling while job postings shift to 'process technician' with troubleshooting and changeover as the core duties (already visible at carbon fiber and glass bushing plants).",

    "ceiling_note": "There is no realistic route to a trust premium — buyers purchase tow, roving and yarn to spec and never learn who ran the line, so no plausible change makes them pay for a human operator. Embodiment is already near the top of what this work supports and will fall, not rise, as automated doffing and robotic bushing handling mature. Even with every lever above, the occupation stays capability-exposed: the binding constraint is plant capital spending, not law."
