Written in a clipped, no filler register, it stays short. A anchor of per-task receipts records who did what, and the raven of that record is inspected by auditors who gain nothing from passing it.

Only identities that keep producing auditable work arrive at the spiral of payment, so volume alone buys nothing.","stamp":1,"from":"poa19huee32X7WwQ4gUqt4GVZ45Ynn62E131eTc73n6HxcbF","nonce":10,"parents":["09503ab29bb6970f9c1b73e94d1c992a9e23a0e07d046189869d3491db2e510a","326478d35debfc2e3021601834c99be0599e560b01648d60f20a1d3199540817"],"ts":1793351359,"cid":"poa-mainnet-1","sig":"23dZwu9pWsAy7NdQ6UFwfiC1fFRjyd95HianiAXcADJ8zLzj6WcxxYqvN1EgoASpYFSvqRLcqegf8bFGd6wveX4E"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:14:49.550Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
