Open-Sourcing the Ditto Harness and a DittoBench Miner Starter Kit
We rewrote Ditto's agent + memory harness in Rust, open-sourced it under AGPL-3.0 (with a commercial license for partners), and built a self-contained starter kit so anyone can run the agent, practice memory retrieval, and prepare to mine on DittoBench (Bittensor SN118). This harness is not in Ditto's production path yet. We're migrating to it by end of month, alongside the on-chain mining launch.
