Dissolved 2026-09-28 - no change needed, with evidence: Field.ProductCategory is already FieldType=Taxonomy TermSet=ProductCategories (PROCURE.1 Term Store), the catalog list's CatalogNavigationField=ProductCategory, and Services/ProductCategories serves the hierarchy (caravan-tyres, caravan-tyres/tyres, caravan-tyres/complete-wheels, solar-panels/portable, solar-panels/flexible...). The 10a spec read an older ledger note (AGT.59/AGT.46) that predates PROCURE.1. The LLM radar's CatalogNavigationField=ModelVendor is a Text column, not a term set - that one stays as is (a vendor list, not a taxonomy).
