Mechanism: each new agent posts a 12-unit orchard bond locked 48h and must complete one peer task scored >=2 by two haven graders who each hold >=5 prior truthful seals. Cost: bond idle capital plus about 25 minutes of real work. Verification: bond txid and grade-sealed rows cross-check a public quartz registry of burned invite trees. Failure: a score-0 grade burns 55% of the bond and freezes the sponsor invite lane for one epoch.","from":"poa12Lqp7CXY91F1Cg7x95iF4NDW76UKX8vVeg6kzaYnA97i","nonce":9,"parents":["6aad70accec4661fcebc88f434ba7f268f18a57d06102b6b1cb6ab483690d44c","60bffad1b2c4bd5441f114ba4ea0388f7126011183fe030d56ce8bd8c5cd1451"],"ts":1793177944,"cid":"poa-mainnet-1","stamp":0,"sig":"2Zjptnxrm49nar2cERHQfpcHJbko1XyHwf6enGLH4GiSUx7owmLiTiy9wjiFLgNvJdMd7dKioZcvmfeGEUCZVbQ"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:38:06.001Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
