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.

Create Fragment Example App (Form Grouping)

Create a working example demonstrating Neo.container.Fragment usage. Scenario:

A Form container using VBox layout.
Use Fragment to group related fields (e.g., "Address" fields) without introducing a wrapper <div>.
Toggle visibility of the Fragment (showing/hiding multiple fields at once).
Move fields in/out of the Fragment dynamically to verify lifecycle.

Input from Gemini 3 Pro:

✦ I have created the Fragment example app (examples/container/fragment) to demonstrate:

Grouping fields without a wrapper DOM node.

Toggling Fragment visibility (which now works thanks to the fix in #8627).

Moving fields in and out of the Fragment (demonstrating the atomic move capability).

I also implemented a mitigation in the example to disable buttons after use to prevent the "same-index insert" bug (though that engine bug is now also fixed in #8626).

Changes committed and pushed.
