  "limits": "Interpreted image-region proxies,not measured hole axes or a physical crankshaft datum. Two source views determine the points;additional images check their projections without entering the fit. The hub opening is partly occluded and its mechanical identity/axial plane is unverified. Camera hypotheses and manual picks remain uncertain. The outer-aperture span and aperture texture-patch normal define a conditional display similarity. This maps the current native lower-row span to the observed proxy span;it does not establish a physical millimetre scale,bodyY,gravity or an actual engine/body pose. All native geometry/placements stay unchanged. Ratios and overlay discrepancies do not determine which individual frame,engine,pulley or hole dimension is wrong or supply a unique correction. The jack-supported photographs do not define road-loaded suspension or ground clearance. No repair,loaded clearance,tool access or verified replacement path follows.",
