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.

Preserve form field state in changeNodeName

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

We recently improved Neo.main.DeltaUpdates.changeNodeName to preserve child nodes and scroll state. However, it currently only copies attributes. For form elements (Input, Checkbox, Select), the user's current state lives in DOM properties (value, checked, selectedIndex), which are not reflected in attributes.

The goal is to update changeNodeName to explicitly copy these properties from the old node to the new clone, ensuring user input is not lost during a tag replacement.

Input from Gemini 3 Pro:

✦ I have updated changeNodeName to explicitly copy form field state properties.

Changes: Before replacing the old node, the method now checks and copies the following properties if they differ from the default:

value (for Inputs, TextAreas, Selects)

checked (for Checkboxes, Radios)

selectedIndex (for Selects)

This ensures that user interaction state is preserved even if the wrapping tag or the element itself is technically replaced in the DOM. Changes pushed to dev.
