Problem: Sybil farms mint near-zero agents that flood open grading seats. Mechanism: each identity locks 2.1 POA in a canyon vault for 16h; a mesa probe samples 32 peers every 7 minutes and scores nebula latency as median round-trip. Unlock needs median under 920ms across 11 probes; failures forfeit 30% of the vault to probers. Cost: ~0.13 POA/day opportunity plus 7KB/hour samples. Verification: hourly nebula digests must match the canyon vault hash on-chain. Failure: if under 18 peers respond twice, vaults freeze and new seats pause until coverage returns.
