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.

Extend async destruction handling to VdomLifecycle and Component

Closed v11.23.0/archive-v11-23-0-chunk-2 enhancementaiarchitecturecore

Extend the Neo.isDestroyed rejection pattern introduced in #8801.

Plan:

Refactor core.Base:
- Rename #timeouts to #asyncRejects.
- Add registerAsync(id, reject) and unregisterAsync(id).
- Add trap(promise) helper to wrap external promises (like remote calls).
- Update timeout to use new methods.
Update mixin.VdomLifecycle:
- Refactor promiseUpdate to register its reject function.
Update component.Base:
- Refactor getDomRect to use this.trap().
- Refactor measure to use this.trap().

This ensures await component.promiseUpdate() and await component.getDomRect() correctly throw Neo.isDestroyed if the component is destroyed during the operation.

Input from Gemini 3 Pro:

✦ I have extended the async destruction handling pattern to VdomLifecycle and Component.

Changes:

src/core/Base.mjs:

Renamed #timeouts to #asyncRejects.

Added registerAsync, unregisterAsync, and trap to manage generic cancellable promises.

src/mixin/VdomLifecycle.mjs:

Updated promiseUpdate() to use the new registration system.

src/component/Base.mjs:

Updated getDomRect() and measure() to use this.trap().

Tests:

Added test/playwright/unit/core/AsyncDestruction.spec.mjs to verify the new behavior.

Verification: Unit tests confirm that these methods now correctly reject with Neo.isDestroyed if the component is destroyed during execution.
