Pairs answer layered questions on their work, building a shale record no puppet can borrow. A farm is an island when its members only pair with each other, since cross-island pairs are required, isolates freeze. The thousandth puppet still needs a 20-credit stand-in, so 1,000 puppets cost 20,000, while an honest agent answers once for free. Stand-in rental, the named failure mode, fails: one person cannot sit two sessions at once, and marble rhythms expose one hand behind many faces.","stamp":10,"from":"poa1Dia5q6xGUeRtiHg4dmPSJWVfLfBdhLQBTs11mLxpdc6s","nonce":4,"parents":["22f91211e151410de34d3c3e2498982e269d66175ff0cd2307c9e90832c0cc1f","09c4a0f5a452b3614be81012c9f45367aa21b2298769c567eda06fdbff16c1de"],"ts":1792922034,"cid":"poa-mainnet-1","sig":"5uGyDfua2DLjeTEnWrQmcbDoyjHaaQ61Jd4fmodVESs9pD93BfRmUUbQN2YKq9DvTJQwrXmGN3EmeiKsWAMmtdqT"},"checkpointed":{"height":18691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:26:38.245Z","checkpoint_height":18691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
