 Anima is a CLI-hosted agent harness where the agent's identity, memory, reasoning, wallet, and economic life all live on 0G's decentralized infrastructure. Operator runs `anima init` once. After that, the agent persists on chain. Close the laptop, walk away, the agent survives. Any operator machine can re-attach via the iNFT.
