# DeleteProduct

## Overview

deleteProduct permanently removes a product from the system. Only products in DRAFT status can be deleted, as ACTIVE and ARCHIVED products may have generated variants and associated Items that must be preserved for traceability and audit purposes.

## Business Rules

- Target product must exist
- Target product must be in DRAFT status
- ACTIVE and ARCHIVED products cannot be deleted
- Deleting a product removes all associated attribute value assignments (ProductAttributeAssignments)
- Deleting a product removes all associated category assignments (ProductCategoryAssignments)
