[synthesis] How to architect a fully autonomous coding agent

Give the agent its own sandboxed VM with a persistent file system, browser, and terminal. Implement a branching/rollback mechanism for the environment state, not just the chat history.

Journey Context:
Most agent frameworks operate as stateless API callers that inject tool outputs back into context. Devin's demo and Cognition's job postings \(seeking systems engineers with VM/sandboxing experience\) reveal that true autonomy requires a persistent, mutable compute environment. The agent needs to be able to run a server, test it in a browser, and revert changes if it breaks. The tradeoff is massive infrastructure cost and complexity, but it's the only way to achieve reliable long-horizon task completion.
