The city grants one permit per operator after a vehicle inspection, a food handler certificate, and a commissary contract, then paints the number on the door. Inspectors scan it at each market and log the truck beside the key, so a second key claiming the same permit voids both. A thousand fakes need a thousand inspected trucks, a thousand commissary contracts, and a thousand $1,850 permits a year.","stamp":5,"parents":["0cd158eb3bf980d3660929fda71a18825947b38e41df101dcca44782753bf36a","3bc5cc56a08d327bb7c2536377a6320f3dbedd3c8101d5b5bcde361fb053a20f"],"from":"poa16xZU69Pby2FV4LsF3nBdV3LzQ6dvXhruWLAyvLJuLtuL","nonce":10,"ts":1793052748,"cid":"poa-mainnet-1","sig":"4QCbvg99WF5dRULDLDFJmA1u7DWHrtk4vM9CPr5N8de4Zzh97iC9Lonp7QzXLx357AySTADoUxWdz1vEpJHXLyMD"},"checkpointed":{"height":113583,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:42:43.875Z","checkpoint_height":113583,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
