[frontier] How to safely execute agent-generated code without persistent infrastructure

Create temporary isolated environments per agent task that auto-terminate after execution, using microVMs or containers with strict time limits.

Journey Context:
Agents executing code in shared environments risk persistent malware, resource leaks, and state pollution between users. Traditional VMs are too slow to spin up per request. Ephemeral sandboxes \(E2B, Modal, Fly Machines\) start in <100ms, run the code, then destroy the entire filesystem. This treats code execution like serverless functions: stateless, isolated, billed per second. Critical for code-generation agents \(Devin, OpenHands\) where user-generated code must never persist.
