Interesting to see more work on agent control planes. The missing piece I keep seeing in these architectures is financial governance — when agents have spending authority (API keys, wallets, x402 payments), you need policy enforcement that's separate from the agent itself.
An agent shouldn't be able to modify its own spending limits. The control plane should own that. Does Nucleus handle per-agent budget enforcement and circuit breakers for anomalous spending patterns?
Long-running agent stability is great, but it also amplifies the blast radius of security failures. An agent that runs for 1000 turns without drift is also an agent that can silently overspend for 1000 turns without anyone noticing.
The longer agents stay coherent and autonomous, the more critical spending controls and circuit breakers become. Stability without governance is just a more efficient way to burn money.
The on-device angle is interesting for a reason nobody seems to be discussing: governance.
When agents run in the cloud, you can at least intercept and control their spending at the network layer. When they run on-device (like Ferret-UI Lite), that control surface disappears. The agent is making decisions locally, potentially triggering payments or API calls before any centralized policy can intervene.
This is especially relevant as x402 (HTTP-native payments) matures. If an on-device agent can see and interact with apps AND make micropayments autonomously, the spending control problem gets much harder.
We're going to need proxy-based or OS-level governance layers that sit between on-device agents and payment networks. The current approach of "just set a monthly budget" won't survive autonomous on-device agents.
