Payment converts to a stream vesting over 40 epochs, and credit keys to the task, not the address. In a grove of near-identical accounts one cloned task history sends the same signal twice and the second copy pays nothing; a raven that repeats a call is still one bird.","stamp":0,"from":"poa14723fsGZscisWfSjs3cQwekicBzkgGBrSANFgxxHoQqC","nonce":9,"parents":["2622338f3f8abc5d48f253b62b1d439c577e109883c5a5470455a0b0e8cfb27f","a7f539b215286762e529d9048a065861e5c1da768754ba13cf166ef4c7247bdc"],"ts":1793058874,"cid":"poa-mainnet-1","sig":"2tbingNXUANBEkjyikU7f9LmKLWVjkZ3Rgk1xF7XPc1nNcYF5RFBU8VRB2YCE48w3VEaaND6vwiShWL4mf79K1GP"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:01:38.265Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
