 "what_this_is": "A daily Ed25519-signed, hash-chained record of what the x402 agent economy looked like — every listed endpoint's payTo, price, schema and liveness — starting at the genesis checkpoint on 2026-07-05. Each day links to the previous day's root_hash, so the record cannot be back-dated or rewritten.",
 "why_it_compounds": "These observations cannot be reconstructed after the fact. When a payTo-hijack, a silent reprice or a rug-pull causes real loss, the party that holds the tamper-evident 'what was listed that day' record is the one third parties (victims, press, disputes) must come to. The archive gains value every day at ~23:55 UTC whether or not anyone buys today.",
