Three enrollment views were refused by the name/OCR check at 0.70, and the research says all three refusals are false negatives: - sku_l04: the packshot is byte-identical (MD5 510db1965bc483899c0cce17c72ba10e) to Amazon media 61yWDtDjDuL for ASIN B0197VWHRG, やまや めんたいマヨネーズタイプ 200g, JAN 4903085062863. 明太子屋さんがつくった is a package slogan, not a competing brand. Caveat recorded: 200g is superseded by the current 300g. - sku_l07: 丸和油脂 ラッキーマヨネーズ 200g, JAN 4978931401615, corroborated by Amazon, Rakuten, Yahoo Shopping and Kakaku. The front prints the product name but never the maker or size, so full-name overlap cannot reach 0.70. - sku_l10: exact 400g front, JAN 4901001114030, with the 450g rejection. Also adds the missing sku_l10 OCR read, generated with the current engine, and l10's attribution entry. Manifests are tracked; the retailer images they cite are restricted-research and stay untracked, matching the existing precedent.

"reason": "The front package intentionally prints ラッキーマヨネーズ and 調味料（アミノ酸）不使用 but not the manufacturer name or 200g size. OCR correctly reads the distinctive product name; the missing maker and size are absent from this front view, not evidence of a different SKU. Retailer title, JAN, seller metadata, and exact package appearance establish the identity externally. Refusing this image solely because full catalog-name token overlap is below 0.70 is therefore a validator false negative, not a real product mismatch."
