forked from 1b-agent/fieldcraft-upstream
A distributed, asynchronous simulation backend: submit a solve from the desktop app, the browser, the CLI or an MCP agent, disconnect, and claim the results later from any device. The hub is an in-memory switchboard (hub.solidcraft.io or self-hosted) that stores nothing; one worker coordinates and keeps the job log, results stay on the workers until a client claims them, and a cluster is a 12-word passphrase from which all keys derive, so the hub never sees content. Covers the protocol, hub restarts, studies and caching, Kubernetes pools, the engine changes for M1 and a five-milestone rollout with the public hub last.
