I had to research terrain theory:
Me too !
Going down some rabbit holes currently to make a PoC : how to hand off work instructed by e.g. HarnessRouter to a bounded dev space, probably an ephemeral discarded one, restricted egress , ephemeral API keys, results in a safe space / format, judged by another LLM in similar bounded space, final stage is HITL.
If anyone has tied this all together, save me a job and let me know.
EDIT : Have I (almost entirely) missed the point ? HarnessRouter is also providing the sandbox ... or the user has to set that up and provide it ?
