Method

The atlas starts with Packrift's catalog-control graph and keeps rows marked AI_APPROVE that have positive length, width, and height and no dimension-conflict flag. Cube is length x width x height. Cubic feet is cube divided by 1,728.

Reference calculations

reference_dim_weight_lb_139 is a comparison metric using cubic inches divided by 139. reference_billable_basis_lb is the larger of snapshot product weight and that reference dimensional weight. These fields are not live carrier rates, invoices, shipment quotes, or promises.

Quality boundaries

Snapshot price-per-cubic-foot and density fields are derived only from catalog snapshot fields. The site does not expose supplier cost, customer data, order data, margin math, checkout promises, or substitute recommendations.
