  "basis": "Factory141 supplies the handed complete dampers and six frame bolt/plain/spring-washer roles. Supplier photographs show a compact rounded body, projecting crossshaft/arms and mounting ears. New bodies share the existing three estimated platform axes and lower bearing plane; kingpin, trunnion, pin and arm-root/tip stations stay.",
  "limits": "Every casting size, hollow volume, ear shape, drilling map, bore, screw/head/washer size, shaft/support section and installed coordinate remains a construction estimate. GSA102/103 andCHA398 are factory comparison roles, not fitted identification. Supplier new/rebuilt/uprated versions are not selected for this car. Existing platform holes, bearing plane, arm roots/tips and upper-joint registration are retained uncalibrated references. Hollow case has no verified piston, valve, hydraulic passages or fluid volume; crossshaft bore is not a loaded bearing or seal fit. Smooth shaft/root-eye interfaces are unloaded construction relationships, not splines, loaded clamps or torque transfer. The flat arm sections, bent plan, root eyes and case-to-arm spacing are estimates, not fitted clearances. Mounting bolts are unthreaded35mm display envelopes; no supplier/factory bolt length or terminal diameter is assigned. The smooth lock-washer rings are unloaded role cues, not spring geometry or compression. No damping performance, angular motion, alignment, stored spring load, strength, thread ownership/engagement, torque, tool access, support sequence or verified damper replacement/removal path. Display separation is illustrative.",
  "handed_profile_scope": "Left/right casing profiles are mirrored construction references; supplier photographs do not verify fitted handed contours."
