Your UCP profile lists no public keys, so cryptographic message signing is not yet enabled for this store. HTTPS already confirms your store's identity; signing adds a further layer for checkout, payment and webhook messages.

Identity & authenticationread from profile

Every request we made was signed (Web Bot Auth, RFC 9421). The profile publishes no keys, so the store's own signed messages can't be checked.

Payment architectureread from profile

Declares dev.boutir.payment.paylink, dev.boutir.payment.bank_transfer. Payment happens inside checkout, which a check never calls, so it shows only in an agent run.
