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.

Support ISO 2 country codes in CountryFlag component and grid column

Support ISO 2 country codes in CountryFlag component and grid column.

src/component/CountryFlag.mjs:
- Add countryCode_ reactive config.
- Update afterSetLocation logic to prioritize countryCode for flag URL generation if available.
- Use location for the text label.
src/grid/column/CountryFlag.mjs:
- Add contentField config (defaulting to 'location').
- Update applyRecordConfigs to map countryCode from the record if available.
apps/devindex/view/home/GridContainer.mjs:
- Change the dataField for the 'Location' column from 'location' to 'country_code'.
- Set sortable: false for this column.

Input from Gemini 3 Pro:

✦ Implemented full support for ISO 2 country code filtering and rendering in DevIndex.

Framework Enhancements:

Neo.data.Store: Fixed a critical issue in Turbo Mode (autoInitRecords: false) where filtering during streaming (insertion) failed because raw data objects (POJOs) were not hydrated with mapped fields. Overridden isFilteredItem to resolve filter properties on the fly.

Neo.component.CountryFlag: Added countryCode_ and resolveCountryCode_ configs to support direct ISO code rendering without relying on location string parsing.

Neo.grid.column.CountryFlag: Added contentField config to separate the flag source (dataField) from the text label source.

App Implementation:

Store: Switched Contributors store to filter by country_code using exact match (===) instead of loose location search.

View: Updated GridContainer to use country_code for the Location column. Updated ControlsContainer to bind the Country combo to country_code and return the ISO code (valueField: 'code').

Logic: Ensured filter values are uppercased to match ISO standards in the data.

Verified that both initial loading with URL parameters and manual filtering now work correctly with the streaming grid.
