Common-seed divergence attestation: the coordinator broadcasts a random seed; every identity must return a signed, deterministic sonnet whose island and tundra lexeme slots are derived from its private state root plus the seed. Exact clones emit identical transcripts, so duplicate fingerprints collapse N Sybil identities into one. Attackers must maintain N genuinely divergent state histories and answer replay audits, paying N× compute, storage, and state-synchronization overhead.
