  "read_scope": "Supplier photograph visually inspected: two side tanks,crossflow horizontal tube rows and dense thin fin field,with upper/lower edge support. This is architecture comparison,not the actual fitted radiator or a calibrated tube/fin drawing.",

  "factory_scope": "Existing documented1500crossflow radiator/tank/hose/cowl roles;factory plate does not supply a fitted internal construction or dimensions.",

  ],
  "owner_scope": "Owner views show installed cooling-stack order,fan/cowl and nearby hoses;core field and hidden waterways are not sufficiently exposed for counting or measuring.",
  "registration_review": "Read coupled-bay-evidence-review and bay-photo-reconstruction-validation. The14-view reconstruction is arbitrary-scale;no new metric common engine/body/mount frame recovered. Existing installed transformations remain.",
  "diagnosis": "The actual active source is lower-hose-connected-reference,whose core is a solid opaque box. Other tank/neck/route groups and separate upper-hose/cowl/fan imports remain;the opaque box is not physical tube-and-fin architecture.",
  "selected_change": "Replace only the opaque core within its422x258x40mm envelope by open flattened crossflow tubes,open header plates and separate sparse sheet-fin comparisons.",
  "dimension_boundary": "24tube levels,two depth rows,3x14mm tubes,.35mm tube walls,1.2mm headers,96flat fins,.15mm fins and all radii/pitches are explicitly selected estimates. No fitted fin count,corrugation,louvres,material,baffles/pass arrangement or seal/braze joint assigned.",
  "limits": "No pressure integrity,flow/heat/airflow model,loaded support,fitted cooling-stack clearance,serviceability or verified replacement/removal path. No source moved to force a clearance result."
