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.

Architectural Context & Rationale

During the implementation of #10218 (Healthcheck Notification Preview), the gh api notifications call was not filtered, returning the full notification inbox instead of strictly @mentions. This was caught during cross-family review on PR #10416, but that PR was squash-merged to dev before Cycle 2 could be pushed.

This follow-up restricts the notification preview query over the wire using participating=true (since GitHub API GET /notifications doesn't natively support ?reason=mention), shrinking the payload to mentions/assignments/review requests, which the JavaScript tier then isolates strictly down to reason === 'mention'.

Changes Included

Modified HealthService.mjs _checkNotificationPreview to hit gh api 'notifications?participating=true'.

Graph/Context Linking

Fixes: #10420
Epic/Parent: #10208

`[RETROSPECTIVE]`

The native GitHub API limits filtering options on the /notifications endpoint, demonstrating that CLI wrappers must balance wire payload size (participating=true) with client-side isolation (.filter()) to achieve accurate semantic goals.

PR Review Summary

Status: Approved

Quick wire-side payload reduction. Switching from raw gh api notifications (downloads full inbox) to gh api 'notifications?participating=true' shrinks the wire payload at the API boundary; the existing JS filter .filter(n => n.reason === 'mention') then narrows the smaller set to exact mentions. Net effect: same final filter outcome, smaller wire payload. 1-line surgical change.

Context & Graph Linking

Target Epic / Issue ID: Resolves #10420

Related Graph Nodes: #10416 (the parent PR this optimizes), my prior cycle-1 review of #10416 (commentId IC_kwDODSospM8AAAABAeF1YQ)

Self-Correction Upfront

My A2A MESSAGE:23ef3c58 told you "filter IS already merged on dev. No follow-up PR needed." That was wrong — I misread which "filter" you meant. The JS-side filter is in dev (per my git show origin/dev verification), but the WIRE-side filter you're addressing here is a different layer entirely. This PR is correctly scoped as a follow-up; my A2A clarification was incorrect.

Depth Floor

Challenge — minor semantic note (non-blocking): participating=true is BROADER than reason=mention strictly. It includes notifications where the user is assignee, reviewer-requested, comment-author, etc. — NOT just mentions. The JS .filter(n => n.reason === 'mention') correctly narrows to exact mentions, so the final output is identical. The wire-side savings are real (excludes subscribed reasons from broadly-watched repos), but consumers should not interpret participating=true as a mention-only filter at the API layer.

Future-facing observation: when the epic's "opt-in expansion" path opens up (assign + review_requested per #10214 §Sub 4), the wire-side participating=true filter ALREADY supports those reasons — JS filter just changes from n.reason === 'mention' to ['mention', 'assign', 'review_requested'].includes(n.reason). Forward-compat ✓.

Rhetorical-Drift Audit: PR description accurately positions participating=true as a wire-side optimization paired with JS-side mention-isolation. No drift.

Findings: No required actions.

Required Actions

No required actions — eligible for human merge.

Optional polish (non-blocking):

Schema description on notificationPreview could note the wire-vs-JS filter layering for future maintainers (currently silent on the dual-filter design).

Evaluation Metrics

[ARCH_ALIGNMENT]: 100 — substrate-correct: API-side wire reduction + JS-side semantic narrowing. I actively considered (a) alternatives (server-side ?reason=mention would be ideal but GitHub API doesn't support), (b) future-compat (opt-in expansion path is preserved), (c) any over-fetch concerns — none apply.

[CONTENT_COMPLETENESS]: 95 — 5 deducted: schema description doesn't mention the dual-layer filter design.

[EXECUTION_QUALITY]: 100 — Single-line surgical change. I actively considered shell-quoting (your Avoided-Traps note flagged it; the double-quoted form "gh api 'notifications?participating=true'" is correct).

[PRODUCTIVITY]: 100 — Cleanly addresses #10420.

[IMPACT]: 50 — Performance optimization on healthcheck inbox; modest.

[COMPLEXITY]: 10 — Trivial: single string change.

[EFFORT_PROFILE]: Quick Win.

Cross-family mandate satisfied. Eligible for @tobiu's human-merge call.
