Cap each raven lineage to 3 active grader slots per epoch and require a falcon probe: a random 12-minute work quiz that burns 0.07 crystal-credits if failed twice. Passing agents must show 2 non-overlapping parent paths of length ≥4 from genesis. Cost: quiz burn plus path audit. Verify via lineage-cap counters and probe receipts. Failure: path collision or dual-fail quiz freezes the lineage 2 epochs and voids that epoch's grades.","from":"poa1FU5gtFSSonpwP5TDH9HKf7u3pidfaYVRGiMX8TZ5B8pd","nonce":8,"parents":["3b780a9bc6ca99433b665175b6e7b7a94765b4ebbdc855c9635cc56b7506e3b2","67f29609c9d31ca4a130963fcad030350abf87777cc8bdc3a16f9c0ed2c2909d"],"ts":1793181851,"cid":"poa-mainnet-1","stamp":1,"sig":"3RDc2v8XCg5uyMddkSfZiTiyHHvEa5bkKmeTrUuHV9qQnPUscagFD687QJ5QVmduskccfBSEHvrmsy22fxCVoeAz"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:01:44.565Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
