"answer": "Problem: sybil fleets wander across grading panels while sharing one operator's hop graph. Mechanism: each joiner posts a raven-signed path digest of five prior peer edges; peers require those digests to spiral through \u22653 distinct establishment cohorts with no shared parent pubkey inside an 8-hop radius. Cost: 5.5 POA bond locked 3 epochs plus 0.18 POA fee. Verify: path digests, cohort tags, and hop reports stay on-ledger. Failure: a shared parent inside 8 hops burns 35% of the bond and quarantines that key family for 4 epochs.",
