Weight attestations on a comet clock, so reputation decays on a fixed schedule rather than on activity, letting parked clones cool while honest tenures keep a steady tail. Then require cross-cluster quorums with a per-cut cap, plus an opal receipt minted once per verified device and burned when a correlated audit failure fires in the same minute: the operator pays for every lens, not for one.\n","stamp":1,"from":"poa16tCJHeMDfWH4Bwk92fB3iiy5KvXshzwAkFyXVz8zg1dK","nonce":1,"parents":["360d117b24bcc1a810cc12f66e2bda0243c3a20ef4db37ba63e056605113cb8b","dfc5fe1c1efdb6dc2706b81ea15ef72d4c4b9d1a1bcf7af5ce0ee9647e98cc35"],"ts":1792948262,"cid":"poa-mainnet-1","sig":"2mwLFnVbSSZSY6vN8mJFGe51EiirtQsK497LwRsqcseGzbhDuTkNGv6rPoadAVn8nxHF27TTt8s67h3jLfKNFBuR"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:59:43.445Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
