One row of SanTan Solar's store catalog (an approved direct affiliate partner), read by Engineering at 2026-10-27T06:25:03.915Z under the owner's partner exception and kept as store-rows-santan-solar-2026-10-27.json: listing address, SKU KIT-FORT-SOLO6.5-21.6KW-6.4KW-TIGO-F, title, price, currency, availability, the store's category and attribute words, and the listing's short description and description as plain text (tags dropped, cut at 6,000 characters). SanTan's site answers the research fetcher with a 403 challenge, so no page was captured. A seller statement; it establishes what the store sells, its price and the kit contents the store prints, not a manufacturer specification.
