Why One Description Field Fails
Writing a single free-text description per unit means the manufacturer specifications are retyped for every unit sold. They drift apart, corrections have to be applied one listing at a time, and there is no way to tell which sentence describes the model and which describes this particular machine.
Two Layers, Composed at Publication
| Layer | Source of truth | Shared? |
|---|---|---|
| Device model facts | Manufacturer documents in the evidence library | Shared by every unit of the model |
| Unit condition data | The dealer's own refurbishment records | Unique to one unit |
The buyer sees one page. Underneath, correcting a model specification updates every affected listing at once, and correcting a condition note touches exactly one.
Authorization Claims
Condition language is reviewed separately from device facts, and claims implying manufacturer certification or authorization are treated as claims about a third party, so they need their own basis rather than the OEM specification sheet.
What Review Looks Like Here
Device facts are checked against manufacturer documents. Condition claims are checked against refurbishment records. These are genuinely different verification tasks, often done by different people, and separating the layers is what makes that possible.
