The negative control

For every product, does the catalog return the metafield or the merchant description?

ProductKindIn catalogCatalog desc len Metafield lenMetafield in catalogMerchant desc in catalog
P01 FLAT_FACTS found 486 116 no YES
P02 VARIANT_SCOPE found 568 141 no YES
P03 COMPATIBILITY found 410 83 no YES
P04 BUNDLE_COMPOSITION found 570 175 no YES
P05 CONDITIONAL found 428 141 no YES
P06 MATERIAL_SPEC found 422 104 no YES
P07 NEGATIVE_CONSTRAINT found 391 129 no YES
P08 RANGE_EXCLUSION found 445 93 no YES

A "YES" in the metafield column would falsify the assumption that Catalog Mapping is required. It has never appeared in any run.
