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 Portal Learn section tree navigation with removeDom optimization

Closed v11.23.0/archive-v11-23-0-chunk-1 bugai

The src/tree/List.mjs component now uses removeDom for collapsed folders. The Portal "Learn" section controller (apps/portal/view/learn/MainContainerController.mjs) fails to expand parent folders when navigating via deep links, causing the selection to fail because the target nodes do not exist in the DOM.

Fix: Update onRouteLearnItem to use tree.expandAndScrollToItem(itemId) or tree.expandParents(itemId) to ensure target nodes are rendered before selection.

Input from Gemini 3 Pro:

✦ Fixed in 4867a2cf7. Applied logic from News/Tickets controller to properly expand parent nodes before selecting the item, ensuring compatibility with the recent removeDom optimization in Neo.tree.List.
