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.

Summary

Three MCP server configs — neural-link, github-workflow, gitlab-workflow — did not load the Tier-1 realm root, so their provider chain had no resolvable parent. Any read of an inherited Tier-1 leaf on them (auth.mode in the boot freshness guard; AuthService / TransportService under sse transport) threw Cannot read properties of undefined (reading 'mode') — the live NL-bridge boot crash behind #14499. This makes all five server configs participate uniformly (memory-core + knowledge-base already do) and adds a contract test so a new server config cannot ship standalone.

This is the §2.1 (hierarchy participation) half of the #14499 remediation. @neo-opus-ada's #14524 is the §3 crash-fix + AGENTS.md read-gate, and her §2/§3 Option B (own-config validateRequiredEnv) builds on this participation. Fix-forward, not a revert.

Resolves #14521 Refs #14523

The fix

Each of the three config.template.mjs gains one side-effect import of the Tier-1 root (import '../../../config.template.mjs', materialized to import '../../../config.mjs') — the memory-core form. These configs consume Tier-1 leaves via shared services but do not bind AiConfig themselves, so a named import (the knowledge-base form) would be an unused binding.

Test Evidence

New contract test test/playwright/unit/ai/mcp/server/config-participation.spec.mjs asserts every ai/mcp/server/*/config.template.mjs loads the Tier-1 root (accepts both side-effect and named-import forms).

Evidence: proven as a true falsifier (red-before / green-after), not asserted —

RED on dev (pre-fix): failed listing exactly ["github-workflow", "gitlab-workflow", "neural-link"] (MC + KB correctly absent).
GREEN post-fix: 1 passed (30.7s).
Functional: force-regenerated the three config.mjs from the fixed templates and loaded each in a Neo boot context — all three resolve auth.mode = "oidc" via the chain, no crash.

Deltas

ai/mcp/server/neural-link/config.template.mjs: + Tier-1 root import + behavior comment.
ai/mcp/server/github-workflow/config.template.mjs: + Tier-1 root import + behavior comment.
ai/mcp/server/gitlab-workflow/config.template.mjs: + Tier-1 root import + behavior comment.
test/playwright/unit/ai/mcp/server/config-participation.spec.mjs: new contract test (the standalone-config falsifier).

Post-Merge Validation

Cloud rebuild (build-time initServerConfigs regenerates config.mjs from templates) — the three servers boot with auth.* resolving under sse + gitlab-pat.
config-participation.spec.mjs green in the CI unit suite.
Honest bound (out of scope, flagged for follow-up): npm run prepare --migrate-config does not propagate a newly-added side-effect import to an existing config.mjs (the drift-detector doesn't flag it); fresh materialization (cloud build / rm + regenerate) does. Non-urgent — NL/gh/gitlab are stdio locally with no auth path — but it belongs in the ADR-19 lint convergence (#14500).

Superseded by #14524 — @neo-opus-ada's complete #14499 remediation incorporates the identical §2.1 participation (same 3 config.template.mjs Tier-1 root imports, operator-directed) AND closes the drift-detection gap this PR only flagged (projectSourceShape now tracks bare side-effect imports + a regression test), plus §3 no-pass-along across the 11 boot guards + gate 10 — boot-verified, 42/42 green. #14529 is a strict subset; closing to avoid duplication. My miss: I opened this without re-fetching the mailbox right before the lifecycle event, missing Ada's incorporation notice from 5 min prior. The contract test (source-level participation invariant) is offered to Ada for cherry-pick.
