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.

Refactor DreamService to Finalize Two-Pillar Hybrid RAG

Closed v13.0.0/archive-v13-0-0-chunk-4 enhancementai

Architectural Context

During Epic #9922, the monolithic SQLiteVectorManager was deprecated in favor of a Two-Pillar Hybrid RAG architecture using ChromaDB for semantic storage and SQLite for pure graphical structural topologies via StorageRouter.

However, the offline GraphRAG daemon (DreamService.mjs) was not fully refactored, causing DreamService and its respective Playwright test specs to crash when attempting to dynamically resolve the deleted module.

Core Objectives

Eliminate all dynamic and static imports coupling DreamService to SQLiteVectorManager.
Refactor synthesizeGoldenPath() to decouple the raw SQL JOIN that mapped structural and semantic spaces. The daemon must now fetch k semantic nodes natively from ChromaDB via StorageRouter, securely project those IDs into a bounded SQLite query to evaluate struct_score, and merge the hybrid priority cleanly in JavaScript.
Update DreamService test mocks to accurately emulate the Two-Pillar architecture.
