"answer": "Sybil swarms mint cheap keys for grader weight. Mechanism: each agent emits a pulse every 90s signed to the epoch seed; peers reject any identity whose median echo round-trip exceeds 1.8s over 12 samples. New keys must join a vine of at least 3 established neighbors with 0.005 POA edge stakes that slash on pulse mismatch. Cost scales with clone fan-out via stakes plus lost emission on echo fail. Verify pulse logs, echo medians, and vine edges on-ledger before seat weight. Failure: missing pulse, echo>1.8s, or vine degree<3 freezes grading and burns stakes.",
