Review Shipping Weight for a Paper Bundle

Estimate paper stack mass,add supplied packaging weight,then compare parcel and dimensional billing weights with both complete original reports.

• Choose UTF-8 JSON with eight STRING keys:mode,weight,basisWidthInches,basisHeightInches,sheetWidthMm,sheetHeightMm,sheetCount,packagingKg. Mode gsm or basis (pounds per500basis sheets);gsm ignores basis dimensions. Source<=8KiB/4096 characters;single-line fields<=128. Original paper mass plus explicit nonnegative packaging kg uses one binary64 addition. This estimated full parcel mass feeds original shipping arithmetic at supplied outer dimensions cm,divisor,exact/upward-cm rounding and positive billing step kg. Original exact decimal billing ceil and1billion-step limit retained. Bad tare,overmass or unsupported billing values keep the complete paper checkpoint. Raw source,arguments and both full reports remain unredacted. No thickness/moisture/ink/binding/box inference,carrier rates,fees,postage class,universal tariff or measured-weight guarantee. Original30s workers;90s connections.
• Original basisArea=baseW*baseH*0.0254**2;gsm=basisPounds*453.59237/(500*basisArea) or original enteredgsm. sheetArea=widthMm*heightMm/1e6;gramsPerSheet=area*gsm;totalGrams=gramsPerSheet*count;totalKg=totalGrams/1000;totalLb=totalGrams/453.59237. Preserve all original fields/nulls and binary64 order. Bounded owned projection validates explicit packagingKg with unchanged original nonnegative parser0..1e12,then computes packageKg=actual original totalKg+packagingKg using one explicit binary64 addition;String(packageKg) feeds original shipping mass. No paper-only mass mislabeled as full package. This necessary bounded job-specific addition is allowed own processing,not a new general engine/shared machinery. All source/operand values and operation recorded in final manifest.
• Original billed dimensions either Math.ceil each or retain entered Number. volume uses sequential binary64 multiply from1;dimensionalKg=volume/divisor;chargeable=max(actualKg,dimensionalKg). Exact entered decimal rational dimensions/divisor and projected mass decimal string determine max and exact ceil billingSteps;0..1e9 rounded-count bound;reported billedKg=steps*step Number. Preserve all11 native fields/arrays. Nonnegative projected mass<=1e12,positive dimensions/divisor/step1e-12..1e12;original exact decimal limits retained. Overmass,overbillingsteps,invalidtare or consumer controls keep full paper CP/refuse.

• Estimated sheet mass from declared gsm or explicit pounds per500basis sheets plus explicitly supplied packaging tare;no thickness,moisture,stock quality,binding/ink/contents inferred.
