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.

Implement Neo.container.Fragment Class & VNode Support

Closed v11.21.0/archive-v11-21-0-chunk-1 aicore

Goal: Create the Neo.container.Fragment class and enable tag: 'fragment' in the VNode system.

Tasks:

Create src/container/Fragment.mjs:
- Extend Neo.container.Base.
- Set static config tag: 'fragment'.
- Set layout: null (Fragments cannot have layouts as they have no wrapper).
Update src/vdom/VNode.mjs:
- Allow nodeName to be 'fragment'.
- Ensure VNode constructor handles it correctly.

Note: Neo.component.Base already supports the tag_ config, so we leverage that.

Input from Gemini 3 Pro:

✦ I have implemented the Neo.container.Fragment class.

Extends Neo.container.Base.

Sets tag: 'fragment'.

Sets layout: null and prevents layout creation.

Includes safeguard hooks to return null for cls, style, and wrapper variants, ensuring no DOM attributes are accidentally applied to the fragment itself.

Verified src/vdom/VNode.mjs supports tag: 'fragment' via the nodeName mapping.

Ready for next steps in the Epic.
