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.

Description

Resolves #8851 Resolves #9782 Resolves #9783

Implementation of the Neural Link Driven Playwright Integration architecture. This PR introduces White-Box E2E testing capabilities to the Neo.mjs framework without making any structural regressions to the DOM observers. Playwright instances can now actively grab memory-resident component structures.

Extends Bridge.mjs and ConnectionService.mjs to parse role=test and bind appName payloads safely.
Expands fixtures.mjs providing native app.getComponent, app.setProperties to Test runners.
Includes working E2E validation.
