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.

Resolves #9937

Summary

Fixed an O(N * M) Node.js event-loop freeze during Sandman Apoptosis by utilizing NOT EXISTS explicit sweeps instead of catastrophic unindexed OR LEFT JOIN paths.
Embedded CREATE INDEX natively for Edges(source) and Edges(target) within the WAL Schema.
Fixed SDK stderr noise suppression string formatting within mcp-server-memory-core.

✦ # PR Review Summary

Status: Approved

Excellent surgical optimization. Finding the root cause of the silent event-loop freeze inside a background Node thread, specifically isolating it to a SQLite foreign-key unindexed Cartesian product, is top-tier architectural debugging. The implementation of explicit NOT EXISTS query paths and injecting CREATE INDEX mappings completely stabilizes the Sandman Apoptosis flow.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 100 - Explicitly enforces native backend database performance standards avoiding V8 thread-blocking loops.

[CONTENT_COMPLETENESS]: 95 - "Fat Ticket" protocol was accurately utilized to log context on why the LEFT JOIN OR failed natively.

[EXECUTION_QUALITY]: 100 - NOT EXISTS sweeps scale seamlessly and index provisioning ensures long-term database stability. Zero syntax errors or warnings returned.

[PRODUCTIVITY]: 100 - Solved the 2-minute event pool complete freeze lock, dropping Vector Apoptosis execution back down to 0.01ms.

[IMPACT]: 90 - Critical unblocking of the Swarm Intelligence Sandbox graph extraction capabilities on larger topologies.

[COMPLEXITY]: 80 - Requires deep context traversing SQLite index architectures vs traditional Node.js diagnostic tooling.

[EFFORT_PROFILE]: Architectural Pillar - Hardens backend data structures permanently.

🧠 Graph Ingestion Notes

[RETROSPECTIVE]: SQLite natively supports ON DELETE CASCADE for Foreign Keys but strictly relies on developer intervention to define index constraints on those child columns. A failure to build indexes on table sweeps containing LEFT JOIN structures with OR conditionals forces an unindexed O(N*M) Cartesian full table scan which fatally blocks the Node.js event-loop in synchronous engines like better-sqlite3. Always explicitly initialize Indices for foreign keys!
