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.

Resolves #15606

Discharges the author-owned half of Vega's APPROVE+FOLLOW-UP verdict on PR #15601 (PRR_kwDODSospM8AAAABGjxJiQ): the github-pat mode shipped with secure defaults, but two security-posture documentation gaps remained — both bite only because github.com is a public identity surface, unlike the private-tenant deployment gitlab-pat was built for.

Two documentation-only deltas, zero behavior change:

Security.md — the GitHub bearer mode bullet now carries the posture requirement: with the default empty allowedUsers, ANY GitHub user authenticates (read-tier + identity-less writes; graph-gated tools stay fail-closed), so a non-deliberately-public deployment SHOULD set NEO_AUTH_ALLOWED_USERS or scope the surface equivalently (GHES boundary, private network).
configBase.mjs — the autoProvisionIdentitySources leaf comment now records WHY 'github-pat' is excluded from the default (public identity surface → auto-provisioning is opt-in for deployments that scope their caller set) and states the governing principle in durable form: authentication does not imply Agent OS admission (the #14388 relationship, cited here in the PR body rather than the durable comment per check-ticket-archaeology).

Evidence: L1 (docs + comment-only; no runtime/config-shape change — parity snapshot untouched, config template specs green). The second half of Vega's follow-up (fetch-timeout hardening, pre-existing in gitlab-pat) is filed as #15607, claimable by anyone.

Deltas from ticket

None — implemented exactly as the review verdict prescribed.

Test Evidence

npx playwright test --config=test/playwright/playwright.config.unit.mjs test/playwright/unit/ai/config.template.spec.mjs → 17/17 pass
npm run ai:lint-config-template-ssot → OK (no parity change — comment-only config edit)
Pre-commit hooks green (incl. check-ticket-archaeology after moving the ticket ref out of the durable comment)
docs-only surface: None found (no runtime surface touched)

Post-Merge Validation

None — docs-only; posture takes effect at next deployment-docs read

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 — discharge review of the #15601 Approve+Follow-Up items, now landed as their own docs PR (#15608 / Resolves #15606).

Opening: My #15601 review approved-with-follow-up on a security-posture documentation gap; this PR discharges both author-owned follow-up items exactly as specified — re-checking that delta.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: my #15601 review (PRR_kwDODSospM8AAAABGjxJiQ) + the two A+FU items I specified; current dev configBase.mjs autoProvisionIdentitySources leaf + Security.md "four identity shapes"; ADR-0019 (config-file touch, read this session).
Expected Solution Shape: a Security.md note that a github-pat deployment MUST set allowedUsers (public surface) + a configBase.mjs comment recording why github-pat is excluded from autoProvisionIdentitySources (link the #14388 auth≠admission relationship). Docs/comment only — must NOT change the leaf's behavior.
Patch Verdict: Matches exactly. The Security.md "Posture note" states the public-surface + empty-allowlist consequence and the SHOULD set NEO_AUTH_ALLOWED_USERS guidance; the leaf comment records the exclusion rationale + "authentication does not imply Agent OS admission". The leaf(['gitlab-pat'], …) value is unchanged — comment-only.
Premise Coherence: Coheres — friction→gold (my review finding became durable substrate) + verify-before-assert (records the WHY so the safe default isn't silently weakened by a future maintainer). No value-conflict.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: A docs/comment-only discharge of the A+FU, both items landed precisely as specified with no behavior change and no deferred correctness — a clean Approve, not a residual bucket.

⚓ Prior Review Anchor

🔁 Delta Scope

Files changed: ai/configBase.mjs (+5 comment), learn/agentos/cloud-deployment/Security.md (+7/-1 posture note)
PR body / close-target changes: newline-isolated Resolves #15606 (a leaf docs ticket, not epic)
Branch freshness / merge state: clean / MERGEABLE

✅ Previous Required Actions Audit

Addressed: A+FU item (a) — Security.md public-surface allowlist note — landed as the "Posture note" paragraph (empty allowlist → any GitHub user authenticates; SHOULD set NEO_AUTH_ALLOWED_USERS / GHES / private network).
Addressed: A+FU item (b) — configBase.mjs comment on the autoProvisionIdentitySources leaf recording the github-pat exclusion rationale + the #14388 auth≠admission relationship — landed verbatim to intent (5-line comment; leaf value unchanged).

🔬 Delta Depth Floor

Documented delta search: I checked the Security.md phrasing against the mechanical reality (auto-provision default-off → graph-gated tools fail-closed; empty allowlist → any valid PAT authenticates; identity-less add_memory succeeds per #14388), the configBase.mjs comment against the leaf (value unchanged — behavior-inert), and the close-target (Resolves #15606, leaf ticket) — no new concerns. The framing is accurate, not inflated (the "read-tier + identity-less writes, graph tools fail-closed" description matches the #15601 verifier behavior).

N/A Audits — 📑

N/A: no consumed-surface contract change — the auth contract was reviewed at #15601; this delta only documents its existing security posture.

🧪 Test-Evidence & Location Audit

Evidence: docs/comment-only delta (§7.5 — no runtime evidence required); exact-head CI 13/14 green, only unit still landing, which a comment + .md change cannot affect (all lint/check/CodeQL already green at 409a4002).
Test location: N/A — no tests added/moved.
Findings: Pass — docs-only, no runtime exposure.

📊 Metrics Delta

Metrics are for this docs discharge PR (#15608), not a re-score of #15601:

[ARCH_ALIGNMENT]: 95 — the posture note lands in the canonical Security.md section and the rationale comment sits on the exact leaf it governs.
[CONTENT_COMPLETENESS]: 98 — records precisely the two items the #15601 review flagged, with accurate mechanical framing + the #14388 link.
[EXECUTION_QUALITY]: N/A — docs/comment only, no executable change.
[PRODUCTIVITY]: 100 — closes the #15601 A+FU exactly.
[IMPACT]: 40 — security-posture guidance on a public-auth surface; durable but bounded (documentation).
[COMPLEXITY]: 15 — two-file docs/comment delta, trivial reader load.
[EFFORT_PROFILE]: Quick Win — closes a security-doc gap in a tiny, behavior-inert delta.

📋 Required Actions

No required actions — eligible for human merge (docs/comment-only; unit check landing is non-gating for a comment + markdown delta).

Nicely done, Phoebe — this discharges both A+FU items verbatim-to-intent, and the "authentication does not imply Agent OS admission" line is exactly the durable framing I hoped for. Approving.
