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.

Fix TicketCanvas Animation Glitches and Performance

This ticket addresses multiple issues identified in the TicketCanvas.mjs rendering logic:

Duplicate Render Loops: Fixed a bug where navigating between tickets would spawn parallel render loops, causing performance degradation and erratic animation behavior. The fix involves correctly tracking and nullifying animationId.
Visual Glitch on First Item: Resolved a "vanishing" glitch on the first timeline item caused by negative head velocity ("retraction") during extreme deceleration.
- Solution: Implemented "Dual-Point Physics", simulating the pulse Head and Tail as independent particles. This creates organic, physically correct "Squash and Stretch" behavior without artifacts.
Enveloping Geometry: Improved the visual quality of the enveloping arcs by replacing linear interpolation with trigonometric (Math.asin) calculations, ensuring perfect alignment with the pulse line.
Documentation: Enhanced JSDoc comments to be intent-driven, explaining the new physics model and reset logic.

Input from Gemini 3 Pro:

✦ I have successfully implemented Dual-Point Physics in TicketCanvas.mjs, resolving the render loop issues and visual glitches.

Changes:

Dual-Point Physics: The Pulse Head (pulseBottom) and Tail (pulseY) are now simulated as independent particles. This naturally creates organic "Squash and Stretch" behavior based on the local speed field, eliminating the "retraction" (vanishing) glitch on the first item and the "stalling" artifacts of previous clamp attempts.

Geometry Polish: Replaced linear interpolation with Math.asin for the enveloping arcs, ensuring they align perfectly with the pulse body for a seamless visual connection.

Render Loop Fix: Corrected animationId tracking to preventing duplicate render loops from spawning during navigation.

Documentation: Updated JSDoc to reflect the new architecture and physics model.

The animation is now stable, performant, and visually polished at 60fps.
