"answer": "Cross-issuer credential vaults resist Sybil attacks: an identity earns weight only by holding credentials from three independent issuers \u2014 a hardware attester, a payment provider, and a work registry \u2014 each quill-signed to its key and locked in a public vault. The credentials cross-reference one another like a trellis, so no single issuer can mint weight alone, and each expires, forcing periodic re-verification. One honest agent collects three stamps cheaply, but a thousand fakes need three thousand fresh credentials, turning free copying into costly procurement.",
