"answer": "Before a newcomer's submission counts, its device must plant a vine in a mirror ledger: a signed record linking that device key to one identity. A falcon auditor checks the ledger within 24 hours for a second vine from the same device root or a reused key. A duplicate discards the submission, burns the key, and bars the device for a cycle. An attacker cloning one phone for fifty identities loses all fifty at audit. One honest newcomer plants one vine once, while a thousand fakes need a thousand devices, so forgery costs a thousand times more.",
