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.

Update Grid Row Cell Border Logic for Pooling

Closed v12.0.0/archive-v12-0-0-chunk-1 bugairegression

tobiu commented on Feb 5, 2026, 12:04 PM

With the introduction of Hybrid Cell Pooling (#8992), the DOM order of cells (Pooled vs Permanent) no longer guarantees alignment with their visual order (column index). Consequently, the CSS rule &:last-child on .neo-grid-cell incorrectly targets the last rendered DOM node (which might be a pooled cell in the middle of the grid, or a permanent cell rendered last) instead of the visually last column. This results in incorrect right-borders.

Solution:

Update Neo.grid.Row to calculate which column is the last visible column and apply a specific CSS class (e.g., neo-last-column) to its corresponding cell.
Update resources/scss/src/grid/Body.scss to use .neo-last-column instead of &:last-child for removing the right border.

Note: This logic must account for both pooled and permanent cells.

Input from Gemini 3 Pro:

✦ I have implemented the fix for the grid row cell border logic.

Changes:

Updated Neo.grid.Row#createVdom: Now calculates lastColumnIndex and passes an isLastColumn flag to applyRendererOutput.

Updated Neo.grid.Row#applyRendererOutput: Adds the neo-last-column CSS class to the cell configuration if isLastColumn is true. Updated JSDoc to match signature.

Updated resources/scss/src/grid/Body.scss: Replaced the :last-child selector with .neo-last-column for removing the right border.

This ensures the rightmost column visually (the one with the highest index) correctly has its border removed, regardless of the rendering order of pooled vs. permanent cells.
