Cryptographic proof that a real, present human approved THIS EXACT action - anonymously. No KYC, no wallet score, no biometrics, no hardware. The human confirms with a passkey (Face ID / fingerprint, WebAuthn); you get a signed EdDSA proof bound to your exact action text, plus an anonymous per-service pairwise ID. Use as the human-in-the-loop approval before an agent sends funds, signs, posts, or runs an irreversible action - the anonymous alternative to World ID and KYC personhood.
