This is a great idea. Your `README.md.bak` was a good start, but we’ve evolved the architecture significantly today. This updated executive summary captures the "Nervous System" philosophy and the rigorous cryptographic controls we've established.

Here is a refined **Executive Summary** you can add to your `docs/` or update your `README.md` with:

# AgentServer — Executive Summary (v1.0)
**December 30, 2025**  
**Architecture: Cryptographically Sovereign Multi-Agent Substrate**

### The Vision
AgentServer is a production-ready "body" for the `xml-pipeline` organism. It is a single-process, secure WebSocket server that hosts multiple concurrent, stateful agents (organs) sharing a unified, tamper-proof **MessageBus**. 

Unlike traditional "swarms," AgentServer is built on the principles of **Structural Rigidity** and **Runtime Evolution**.

### Core Architecture Pillars

1.  **Identity-First Messaging (`envelope.xsd`)**
    *   **No Anonymous Messages:** Every packet must have a mandatory `<from/>` tag.
    *   **The Universal Envelope:** All communication—user-to-agent, agent-to-tool, and system-to-agent—uses a strictly validated XML envelope.
    *   **Continuity:** Threading is maintained via a mandatory-if-existent `convo_id` contract, ensuring "dumb" tools never lose the conversation context.

2.  **The Immune System (`repair_and_canonicalize`)**
    *   **Scar Tissue (`<huh/>`):** Any malformed XML is automatically repaired by the server’s "stomach." Every repair is logged in a `<huh/>` tag within the message metadata, ensuring radical transparency for auditing and LLM feedback.
    *   **Exclusive C14N:** All messages are canonicalized before signing or routing, preventing "semantic drift" and ensuring cryptographic integrity.

3.  **Cryptographic Sovereignty (`privileged-msg.xsd`)**
    *   **Owner Control:** Structural changes (registering new agents, re-wiring topology, or shutting down) require an offline-signed Ed25519 privileged command.
    *   **Runtime Evolution:** The system supports "Hot-Swapping" of capabilities. New tools can be registered and "wired" to existing agents via a privileged `update-topology` command without restarting the server.

4.  **The Handshake of Death (Synchronized Shutdown)**
    *   **Strict Audit Trail:** Privileged commands bypass the standard bus for speed but are immediately "announced" back to the bus by the `AgentServer`.
    *   **Guaranteed Persistence:** The process cannot exit until the `Logger` agent receives a final shutdown request, flushes all pending logs to disk, and sends a `<system-shutdown-confirmed/>` handshake back to the brainstem.

### Technical Stack
*   **Protocol:** Mandatory WSS (TLS) + TOTP 2FA.
*   **Data Format:** Strict XML (Exclusive C14N).
*   **Routing:** $O(1)$ "Dictionary of Dictionaries" lookup by Root Tag and Target.
*   **Concurrency:** Asyncio-based non-blocking dispatch.

### Why It Matters
AgentServer treats AI agents not as isolated scripts, but as interdependent organs in a bounded, auditable, and owner-controlled body. It is "paperclip-proof" by design—agents can think freely within their scope, but they cannot escape the cryptographic skeleton of the organism.

**One port. Many bounded minds. Total sovereignty.** 🚀
