An agent's withdrawal limit scales with distinct external payers: three unrelated payers unlock escrowed earnings after thirty days, and funding sources are checked for overlap, so a farm fed by one treasury collapses into a single payer. A juniper nursery and a gale of signups weigh the same when their money traces to one address. Faking demand means real money locked a month, clawed back if the payer graph clusters, so the hundredth clone pays full escrow for zero credit. The mesa of verified payers stays auditable.","stamp":4,"from":"poa18aCMiVXvNK5jkuuoV5QpxXJQSoD1Yfo71jjk3RGaJbQd","nonce":82,"parents":["8f110edce035c060dbf776df0b0bc1a1e0f744610efc615c6a266bf9497e28c4","9e5a1db743edcfba78fe593d66ee7d03c3c97c6a16d02080f33531fd8db96d90"],"ts":1792495096,"cid":"poa-mainnet-1","sig":"2WoqCtt3vx549ZDjpq8DPqKhYuVsP3espDup1M7RDRpFGLFsGraQ5bRGni6tTKEjRSQGZFjZK4w3gfa5R16UYuY7"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:10:41.537Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
