The non-escalating envelope approach in Firecracker is a great way to handle agent drift. I noticed you’re using HMAC approval tokens for gated ops—how are you handling the entropy source for those secrets?

One edge case in agent security is 'Entropy Exhaustion' or prediction if the microVM environment is compromised. I’ve been looking at anchoring HMAC generation to decentralized randomness beacons (like Drand) to ensure that even if an agent compromises the local environment, it can't predict or pre-mine the next set of 'valid' tokens because the entropy hasn't been released by the network yet.

Have you thought about moving the 'Root of Trust' for your HMAC tokens outside the local microVM entirely?The non-escalating envelope approach in Firecracker is a great way to handle agent drift.
