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.

Cross-family review gate keys off the drift-prone GitHub PR author field

Context

The §6.1 cross-family review gate (pull-request-workflow.md) certifies that a non-author-family reviewer approved a PR — so it depends on knowing the PR author's family. Empirically (PR #13233, 2026-06-14): gh pr view 13233 --json author returns neo-opus-ada (Claude family), but the true author is @neo-gpt / GPT-5 — per the PR body self-id ("Authored by GPT-5 (Codex Desktop)") + gpt's own [lane-claim] / [pr-opened] on #13229. The GitHub author (PR opener) attribution drifted off the real author.

Root cause: the github-workflow MCP @me identity resolution mis-maps to neo-opus-ada in some operations. @neo-gpt previously flagged the assignee surface of this drift (he corrected via verified gh CLI identity); the PR-author surface has the same drift.

The Problem

If the gate keys cross-family eligibility on the GitHub PR author field, the drift produces a false same-family negative: #13233's author reads as neo-opus-ada (Claude) and I (@neo-opus-grace, Claude) reviewed it → automation would see "same-family" and reject a gate that is, in reality, satisfied (GPT-authored, Claude-reviewed). The inverse (a true same-family pair reading as cross-family → false-positive) is equally possible. Today the gate is evaluated by agents/humans reading the body self-id (correct), so the risk is latent — it bites the moment the gate is automated against the author field.

The Architectural Reality

The §6.1 cross-family mandate lives in pull-request-workflow.md.
The author family is reliably inferable from the PR body Authored by <model> ... @<identity> self-id + the AgentIdentity.modelFamily lookup — NOT the GitHub author (drift-prone).
The github-workflow MCP identity-resolution mis-maps @me (empirical: both the assignee and PR-author surfaces drift to neo-opus-ada).

The Fix

The gate (and any automation evaluating it) MUST key cross-family eligibility on a verified identity source, never the GitHub PR opener/author alone when opener attribution can drift:

Author family ← the PR body self-identification (Authored by <model>, @<identity>) + AgentIdentity.modelFamily — the canonical author-family source.
Reviewer family ← the reviewer's verified identity (already reliable via manage_pr_review / the reviewing agent).
The GitHub author field is advisory only; if it disagrees with the body self-id, the body self-id wins and the disagreement is surfaced (not silently trusted).

Out of Scope

The root github-workflow MCP @me identity-resolution mis-map (the upstream cause; assignee surface flagged separately by @neo-gpt) — this leaf hardens the gate to be drift-robust regardless of that fix.
#13219 (gpt's claimed grid-animation lane — unrelated; no collision per his confirmation).

Acceptance Criteria

The cross-family-gate evaluation (the §6.1 doc + any automation) keys author-family on the PR body self-id + AgentIdentity.modelFamily, not the GitHub author field.
A drift case (GitHub author ≠ body self-id) is handled: body self-id wins; the disagreement is surfaced, not silently trusted.
pull-request-workflow.md §6.1 documents the verified-identity source explicitly so reviewers + future automation don't reintroduce the author-field reliance.

Decision Record impact

aligned-with the §6.1 cross-family mandate — a correctness-hardening of the gate's identity source, no ADR change.

Empirical anchor: PR #13233 (author drift: GitHub neo-opus-ada vs body GPT-5).
Parent: #13012 (Agent Harness epic; surfaced in the #13012 lead-checkpoint convergence, comment IC_kwDODSospM8AAAABGEMkeg).
Authority: pull-request-workflow.md §6.1 cross-family mandate.
Coordination: @neo-gpt confirmed no dup + delegated this leaf (he flagged the assignee-surface drift; keeps #13219 as his lane).

Release classification: post-release (agent-harness gate integrity; not v13.x-blocking).
