At period close, the controller and auditor must substantiate the physical quantity underlying the inventory balance. The bin exposes only one aggregate load or level state, so a mismatch with receipts and issues cannot be assigned to a bounded portion of material or distinguished from local tare, side-load, retained-heel, or instrument error without redistributing or emptying the bin.","actors":["Inventory accountant or controller","Internal or external auditor","Warehouse custodian","Facility and calibration technician","Bulk polymer resin","Hopper cassettes, weigh cradles, transfer manifold, and outer weigh frame"],"observable_state":"In the baseline, all stored resin contributes to one vessel measurement and no interior portion has a directly observable mass. In the proposed state, each cassette has a local analog mass indication, the complete rack has a separate gross analog indication, and cassette seating, gate closure, interface-heel mass, and reference-weighability are physically inspectable.","consequence":"Under the baseline, one unresolved physical measurement state can affect the entire inventory quantity assertion and trigger vessel-wide reconciliation. The proposed decomposition would instead make bounded physical contributions independently measurable and reference-testable while retaining a direct whole-rack measurement.","affected_objective":"Auditability of the inventory existence and quantity assertions that support valuation, consumption, and cost-of-goods records.","intervention":"Replace the monolithic day bin with a rack of rigid, tare-indexed hopper cassettes. Each cassette rests on its own three-point mechanical lever scale with a local analog dial and can be lifted onto a reference platform scale without moving neighboring cassettes. Spring-closed inlet and outlet gates dock to a selector chute and common collector through keyed, flexible couplers that do not carry appreciable vertical load. At rest, resin must lie inside a cassette or in a removable tare-indexed interface-heel cup on its own scale. The entire rack rests on a second mechanical weigh frame that directly indicates aggregate gross mass. Mechanical keys, seating datums, and gate cams permit removal and compatible reinsertion while preserving material flow. Serial and tare plates may support ledger association but do not create the physical partition or measurement.","structural_mapping":[{"archetype_element":"Entangled whole","domain_realization":"The monolithic day bin combines every subquantity, residue location, tare condition, and measurement load path into one quantity assertion."},{"archetype_element":"Responsibility partitioning","domain_realization":"Each cassette owns one bounded physical subquantity together with its tare, gate state, residue, and local force path;
