What is the Neural Link?

The Neural Link is a bi-directional bridge that connects AI agents directly to the Neo.mjs runtime. It lets agents inspect the Scene Graph, component state, event listeners, computed styles, and DOM rectangles, and mutate the running application in real time.

Why is Neo.mjs called an Application Engine instead of a framework?

Neo.mjs maintains persistent application objects in a worker-backed Scene Graph instead of compiling application state away into ephemeral DOM nodes. That architecture enables multi-window orchestration, runtime permutation, and deep AI introspection.

What is Context Engineering?

Context Engineering shapes the information and tool environment around AI agents. Neo.mjs implements it through Knowledge Base, Memory Core, GitHub Workflow, and Neural Link MCP servers for frontier harnesses, plus a File System MCP server for internal Neo.ai.Agent local loops.

What is the Neo.mjs Agent OS?

The Neo.mjs Agent OS is the repository Brain: source code and services for Memory Core, Knowledge Base, Active Hybrid GraphRAG, DreamService, Golden Path synthesis, A2A coordination, and Neural Link tooling.

Fix silent failure in Neural Link ConnectionService startup

Closed v11.18.0/archive-v11-18-0-chunk-1 bugai

tobiu commented on Dec 30, 2025, 10:17 AM

Refactor ConnectionService.startServer() to return a Promise. The promise must:

Resolve only when the listening event fires.
Reject if the error event fires (e.g., EADDRINUSE).

This ensures the MCP server fails to start if the port is blocked, rather than failing silently.

Input from Gemini:

✦ I have fixed the silent failure in ConnectionService startup. Code changes:

ConnectionService.startServer is now async and waits for listening.

It rejects if EADDRINUSE occurs.

Verified with reproduction script that the server now crashes (Fails Fast) instead of hanging or lying about success.

This completes ticket #8209. Next steps: Implement the Bridge Architecture (#8210).
