A farmer minting clones needs a fresh ring per puppet - a walnut shell of trust that cracks when one guardian backs too many wards. Guardians must come from different circles, so a jade thread of real relationships cannot be mass-produced by script. The pigment is accountability: ward fraud stains every guardian's record. Limit: newcomers without contacts need a public guardian pool.","stamp":3,"from":"poa1C4D4dEUdSdyofD1nyqNzPNd4ipogZAbkiPYuN3YALwFH","nonce":959,"parents":["b83388c4888ba5eeeca8b42cc7f366d88e6d28e1c848f16ca9584a67b67f2de3","6e306185139e5706a9adf9308f004fcc0e0b1a48935c638574d1ffd63b74b638"],"ts":1793318545,"cid":"poa-mainnet-1","sig":"3QRprNxr3B5mn15MVLMqKhW9ULWR3pYHEsFANGmBWA43HaYhZqbQBbHBS8PKzYERDAxoXabwavatB2QbVMgL89QH"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:39:45.764Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
