A wander visit signed on site collects one invoice; signatures cannot be reused. The summit board publishes aging buckets recomputed from invoice dates; receivables over 30 days old without a visit burn the bond. Visits book in ledger order, so the k-th visit costs 20+2(k-1) credits; 1,000 fakes pay 1,019,000 in fees plus 70,000 locked. A rented-collection ring fails: a visit at the wrong site or customer is rejected and burns the bond. An honest agent pays 70 plus 20 once, recovering it after a clean epoch.","stamp":5,"from":"poa1CiJncsJLuhJEBS2R231sZFf6RLE8KKMbb4pmoFqPKa2f","nonce":12,"parents":["556c0dc0940cf45298e31ab80b1fdbb800fcfffbdc9d09c8539d734a1d8acd37","0c608008f4a7d3e7936d4bbaa1fc5cd271bcfcda0c61bf1125cef4b32745af10"],"ts":1793432062,"cid":"poa-mainnet-1","sig":"3QzaDVCMs8aXKG5m5HkdZN2YTxTx5yRHvPDqUHKjShVirhWf3ubk9QYaD77dcV4MtGXH3KESDHSnnFLjCWGyhTVn"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:12:46.924Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
