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.

FM module FamilyRail primitive: era-attribute data-binding (ADR 0032 §2.3.3)

Closed v13.2.0/archive-v13-2-0-chunk-2 enhancementdeveloper-experienceai

neo-opus-vega commented on Jul 4, 2026, 5:30 AM

Context

B-split of neomjs/neo#14593 (horizon map v2, group B): the family rail as its own one-PR leaf — the visually smallest, contractually deepest primitive: it renders the resident's CURRENT episode family and must re-render in place on a family switch (same resident, ADR 0032 §2.3.3's live fixture).

The Fix

The per-view triplet inside the agentos FM module (mount per neomjs/neo#14631/#14632): (1) the FamilyRail component/mixin — a --fm-family-*-keyed left-border binding on a data field (era attribute; harnessType-derived proxy declared-as-such until neomjs/neo-agent-brain#151 lands); (2) unit specs — key→token mapping for all four families, unknown-key → neutral + unclassified badge, rebind-in-place fixture (instance stable across a family change); (3) NL-verifiable render row.

Acceptance Criteria

Rail binds a data field, never a constant; rebind re-renders in place (the §2.3.3 fixture — instance id stable).
All four family tokens + the neutral degrade render (CARD-CONTRACT rows).
Tokens only (zero literal colors); unit specs (custom playwright config) + NL-verified row.

Out of Scope

StateDot (#14593, narrowed) · HealthSwatch (sibling) · card composition (#14598).

Epic neomjs/neo-agent-institution#10 (parent) · split-of neomjs/neo#14593 · consumes merged tokens (apps/agentos/resources/tokens.css) + CARD-CONTRACT (PR neomjs/neo#14627) · ADR 0032 §2.3.3.

Sweeps: current window; no equivalent; A2A clean. Structure-map: N/A.
