Q: Why not just use a local SQLite DB for memory?
Nucleus isn't just a database; it's a Governance Layer. While engrams are stored locally, the value is in the Hypervisor that mediates agent access to that data based on the current task's context.
Q: How is the Audit Trail "Tamper-Proof"?
Every decision and tool invocation is cryptographically signed at the protocol level. If an agent (or an attacker) tries to alter the narrative ledger, the signature check fails.
Q: Does this require a specific LLM?
No. Nucleus is model-agnostic. It works with Claude (via Windsurf/Cursor), GPT-4, or local Llama instances via Ollama. It sits at the MCP (Model Context Protocol) layer.
Q: Is this really "Local-First"?
Yes. No telemetry, no default cloud syncing. The "Agentic Brain" lives in your ~/.nucleus directory. You own the engrams; you own the audits.
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?
Great point. Currently, Nucleus focuses on Sovereign Execution Governance--specifically tool sandboxing and forensic audits. While we don't have native 'financial circuit breakers' in the core protocol today, the Hypervisor layer is designed to mediate exactly these types of tool-level interactions.
We’re mapping out a 'Budget Proxy' capability for v1.1 where you can define hard spending caps per-agent. For now, the Audit Trail provides real-time forensic proof of tool-spend, which is the foundational telemetry needed for manual or automated circuit breaking.
