Vixns Commerce Profile for Universal Commerce Protocol

Vixns Commerce Profile for Universal Commerce Protocol writes an honest business profile JSON to a static file at /.well-known/ucp, can expose UCP catalog REST (search / lookup / product), and can publish keys[] (JWK Set) with rotation for Web Bot Auth type=jwks_uri interop.

This is a third-party WooCommerce integration by Vixns. It is not an official Universal Commerce Protocol product.

• Spec target: 2026-08-25
• Never advertises checkout, cart, or payment handlers
• Private keys stored under uploads/vixns-commerce-profile-ucp/private/ (Apache/IIS deny files are written automatically; block the path on nginx)
• Optional product feed (JSONL), not linked from the profile
• Catalog REST is intentionally open to agents that send a valid UCP-Agent header (same visibility as a public product catalog)
