## Tools (as reported by the server, not verified)

- `get\_passport`: The signed passport of a product \(a Global Trade Item Number, GTIN\) or a retail banner \(market/banner, e.g. FR/Carrefour\): which hub holds its record, where it is on the record, its compliance records, who lists it, where the payment door is. Read live from the GSC hubs on every call; the first call
- `list\_passports`: The passports on the register: ids, kinds, markets, versions and issue times, newest first. No bodies. Filter by kind \(gtin or banner\), market, or issued since a time; paginated.
- `verify\_passport`: Check a passport: is the signature valid, is the chain of versions intact, how old is the stamp, was any section not read. Verifies from the published key at /.well-known/jwks.json.
