Thrive Market returned HTTP 403 to every request, so no page could be opened and it was left out. Ralphs' own site (ralphs.com) timed out repeatedly and is represented only through the Instacart storefront, which is recorded as unconfirmed because that page names neither a product nor Los Angeles. Ghost Town Oats is a Los Angeles oat milk brand, but its own shop at ghosttown.world sells only apparel and patches, so it is listed through the retailers that carry it rather than as brand-direct. Erewhon's category pages return the same JavaScript shell as a deliberately nonsense URL on the same host, so only its product pages, which return distinct real titles, were treated as evidence. Amazon and other marketplace listings were excluded by the brief.
