  "applied": "Steel rim and nominal lining share a simplified32mm comparison envelope centered on the unchanged -2mm local axial station, replacing24mm. Each axial edge moves4mm. Radial layers,177.8mm nominal outer contour,webs,spring eyes,expander slots,cylinder/adjuster maps and both wheel-end frames stay.",
  "limits": "Manufacturer shoe width boundary comparison, not fitted GBS625 or A.B.S. 8606 identity, approved interchangeability or an exact product reconstruction. The rounded 178 mm catalog drum association stays separate from the retained nominal 177.8 mm contour. Applying the 32 mm width to both simplified rim and lining envelopes is a construction interpretation; exact lining margins, chamfers, layer dimensions and developed outline remain unknown. Radial layers, angular endpoints and installed registration remain estimates. Static backplate, drum, shaft, expander and cylinder contacts remain reconstruction discrepancies. No running clearance, wear limit, leading/trailing assignment, loading, friction performance, adjustment or verified replacement procedure is established. No neighboring part moves or owner measurements are applied.",
