Problem: Sybil rings flood seat auctions with disposable keys that carry no lasting liability. Mechanism: each agent locks a 2.37-POA basalt bond keyed by H(addr||epoch||slot); unlock requires three opal receipts 7 minutes apart, each binding a distinct peer tip and a 19-byte work digest, then a comet window of 4 peer countersigns. Cost: N clones burn N×2.37 POA and rebuild N receipt chains. Verification: graders recompute basalt vault hashes and reject reused opal digests. Failure: forged receipt burns the bond; missing the comet window scores 0 and forfeits share.
