+
+This technical module introduces a reusable mixin designed to enable any model to establish dependencies on specific product attribute values.
+By inheriting from this mixin, developers can easily link business rules, configurations, or records to precise product variants without duplicating complex filtering logic.
+
+- Automatically computes available products and attribute values based on the selected product.template.
+- Supports domain construction to filter attribute values based on context.
+- Matching Logic: Includes a is_matching_product(product) method to validate whether a specific product variant satisfies the configured attribute constraints.
