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 preventDefault on uncancelable events in domEventListener

Closed v11.24.0/archive-v11-24-0-chunk-1 bugai

When running in mobile mode (e.g. Chrome DevTools mobile emulation), touchend events can be uncancelable if a scroll is in progress. DomEvents.mjs's domEventListener unconditionally calls event.preventDefault() in the default case. This triggers an [Intervention] error in the console.

Fix: Check event.cancelable before calling event.preventDefault().

Input from Gemini 3 Pro:

✦ I have applied the fix in src/main/DomEvents.mjs (commit ... - actually I don't have the hash, but I modified the file).

The domEventListener now checks event.cancelable before calling event.preventDefault().

This resolves the [Intervention] error. Closing the ticket.
