What is the 'Neural Link'?

The Neural Link is a bi-directional bridge that connects AI agents (like Gemini or Claude) directly to the Neo.mjs runtime. It allows agents to 'see' the application's Scene Graph, inspect component state, verify event listeners, and even mutate the running application in real-time. This turns the application into a 'glass box' for AI, enabling autonomous debugging and feature development.

Why is Neo.mjs called an 'Application Engine' instead of a framework?

Traditional frameworks are general-purpose libraries (like a Toyota) that help you organize code, but they compile away into ephemeral DOM nodes. Neo.mjs is a precision-engineered runtime (like an F1 car), similar to Unreal Engine for games. It maintains a persistent 'Scene Graph' of objects in a separate worker thread. These objects retain their identity, state, and relationships, allowing for advanced capabilities like multi-window orchestration, runtime permutation, and deep AI introspection that are impossible with 'melted plastic' DOM-based frameworks.

What is 'Context Engineering'?

Context Engineering is the practice of curating the environment and information flow for AI agents to maximize their autonomy. In Neo.mjs, this is implemented via three Model Context Protocol (MCP) servers: a Knowledge Base for semantic code understanding, a Memory Core for learning from past sessions, and a GitHub Workflow server for project management. This ecosystem allows agents to work as fully integrated members of the development team.

What is 'Object Permanence' in the context of Neo.mjs?

In Neo.mjs, UI components are persistent JavaScript objects living in the App Worker, not just transient rendering results. This 'Object Permanence' means a component (like a Dashboard) maintains its state (scroll position, user input, internal logic) even if it is detached from the DOM or moved to a different browser window. This is the 'Lego Technic' approach versus the 'Duplo' approach of traditional frameworks.

What is an 'Agent Operating System'?

Neo.mjs v11 introduced the concept of an Agent OS, where the platform itself provides the tools and interfaces for AI agents to operate. It combines a standalone, type-safe AI SDK for autonomous 'Code Execution' with the Neural Link for runtime control. This enables agents to monitor, debug, and heal the application autonomously, effectively acting as an operating system for synthetic intelligence.

How does Neo.mjs handle multi-window applications?

Neo.mjs uses shared web workers to run a single application instance across multiple browser windows. All windows share the same application state and data in real-time. Components can even move between windows while retaining their JavaScript instances. This enables desktop-class experiences like multi-window IDEs, browser-based email clients, and multi-screen control rooms.

What makes Neo.mjs different from React, Angular, or Vue?

Neo.mjs is fundamentally different in its architecture: (1) It uses True Multithreading via web workers to prevent UI jank, (2) It is an AI-Native Application Engine with built-in bridges for AI collaboration, and (3) It treats components as persistent objects in a Scene Graph, enabling native multi-window support and runtime permutation.

Clean up SourceParser and use Class Hierarchy

Name: Neo.mjs Application Engine
Author: Neo.mjs

Closed v11.19.0 airefactoring

tobiu commented on Jan 8, 2026, 2:50 PM

Now that docs/output/class-hierarchy.json is the single source of truth for the class hierarchy, the SourceParser logic can be simplified and improved.

Issues:

Remove Flawed Logic: The SourceParser still contains the heuristic logic for resolving superClass (imports map + path resolution + heuristic app naming) which was deemed "messed up". This should be removed.
Use Hierarchy File: Instead of guessing the superClass from imports, SourceParser (or rather ApiSource calling it) should look up the extends property from the authoritative class-hierarchy.json.

Plan:

Refactor SourceParser.mjs:
- Remove the complex import mapping and heuristic resolution logic for superClass.
- Accept an optional hierarchy object in the parse() method arguments.
- If hierarchy is provided, look up the extends value using the extracted className.
- Fallback: If not in hierarchy, leave extends empty or null (better than guessing wrong).
Refactor ApiSource.mjs:
- Load docs/output/class-hierarchy.json at the start of extract().
- Pass this hierarchy map to SourceParser.parse().

Goal: Ensure vector metadata (className and extends) is populated using the authoritative hierarchy data, removing all "hallucinated" heuristics.

Input from Gemini 3 Pro:

✦ I have refactored SourceParser and ApiSource to implement a clean, authoritative inheritance resolution.

Changes:

SourceParser.mjs: Removed the flawed import-mapping and heuristic superClass resolution logic. It now accepts an optional hierarchy object and performs a simple O(1) lookup: superClass = hierarchy[className].

ApiSource.mjs: Now loads docs/output/class-hierarchy.json at the beginning of the extraction process and passes it to SourceParser.parse(). It includes a warning if the hierarchy file is missing (to avoid silent failures).

This ensures that the vector metadata (extends) matches the authoritative JSDoc-generated hierarchy, removing all hallucinated or guessed relationships.
