A2A-Passport.ai — one GTIN, one call, everything GSC knows, signed.
A passport is a signed document for a product or a retail banner: where its record lives, where it is cleared, who lists it, where the money door is. Issued live from the GSC hubs, stamped every week.
GTIN is the Global Trade Item Number — the number under a product's barcode. GSC is GreenCore Solutions Corp. A banner is written market/banner — FR/Carrefour.
