# Architecture Decision: Provider Product Mapping ## Status Accepted ## Decision Provider mappings are first-class Product-level records. During new Product creation, configured pricing providers are searched for candidate matches. The admin confirms the appropriate match, refines a search manually when necessary, or marks a provider Not Applicable. Mappings are reused by all physical Inventory Items belonging to the Product. ## Mapping types - `PRODUCT`: specific canonical provider/catalog entity. - `SEARCH`: provider search/query definition. eBay supports both mapping types. ## Rationale A provider relationship describes the identity of the Product, not a particular physical copy. Keeping it at Product level avoids repeating provider discovery for every copy while supporting multiple conditions and future copies. A search mapping is necessary for providers such as eBay where a canonical product may not exist for every collectible or merchandise item.
