Could you build this?

Partial Connecting an agent runner to Temporal workflows is achievable, but building a reliable, deterministic verification environment with secure multi-tenant microVM sandboxes is difficult systems work.

What it would actually take: The architecture combines Temporal for durable workflow orchestration with Firecracker or gVisor microVMs for code execution sandboxing and git-based evidence capture. The challenging part is creating deterministic execution environments that reliably record, replay, and verify software builds and test runs without flaky environment leakage. Requires expertise in distributed systems orchestration, hypervisor-level virtualization, and Linux container isolation.
