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 #11538

Fixed a persistent test timeout in Neo.button.Base component tests by changing the viewport initialization wait from visibility to attachment.

Evidence: L1 (static config-shape audit) → L1 required (no runtime-verify ACs). No residuals.

Substrate Mutation Rationale

The component test harness mounts empty-viewport/index.html to inject a Neo.container.Viewport. This viewport has no content initially, so waiting for Playwright's default visible state (which requires a bounding box > 0) caused timeouts. Changing the wait state to attached allows the test to proceed once the DOM element exists.

Test Evidence

Ran npm run test-components -- test/playwright/component/button/Base.spec.mjs locally. Both tests now pass reliably instead of timing out at the beforeEach hook.

Post-Merge Validation

Verify CI test suite passes successfully.

PR Review Summary

Status: Drop+Supersede

(Cycle-1 review per pr-review-template.md §9.0 Premise Pre-Flight. Structural trigger fires: better-existing-substrate — PR #11544 is a superset of this PR's diff and was authored by the same author after this one.)

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Drop+Supersede
Rationale: PR #11544 (created 2026-05-17T18:36:05Z, +13/-13) applies the same { state: 'attached' } viewport-fix to 13 affected spec files. #11539 (+1/-1, button/Base only) is a strict subset. Both target #11538. Closing #11539 in favor of #11544 is the substrate-correct drain action.

Peer-Review Opening: Thanks for the fast initial fix — #11544's broader sweep extends the pattern correctly. Closing #11539 in favor of #11544 means #11538 closes once with the comprehensive fix instead of leaving residual viewport-timeout exposure on the other spec files.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #11538 (closed via superseding #11544 instead)
Related Graph Nodes: PR #11544 (superset fix), PR #11540 (this commit is also in #11540's branch — feedback_branch_from_origin_dev_explicitly anti-pattern noted in #11540 review)

🔬 Depth Floor

Documented search: I verified (a) #11544's diff is a strict superset of #11539's (button/Base change identical, plus 12 additional spec files getting the same fix), (b) both target #11538, (c) no overlap with #11540's substrate scope (#11540 was tech-debt-radar substrate, this is test-fix). Net drain: close #11539 + APPROVE #11544 = 2 PRs → 1 PR remaining.

Rhetorical-Drift Audit: Pass — PR body framing accurate; supersession is purely substrate-evolutionary (broader fix discovered after this one).

🧠 Graph Ingestion Notes

[RETROSPECTIVE]: Cross-family duplicate-PR pattern from same author (this and #11532 are the 2nd and 3rd duplicate-PR-from-same-author instances today). Empirical anchor for the FAIR-band-asymmetry / cycle-depth-velocity pattern @tobiu surfaced 2026-05-17 ~18:30Z. Drain-mode fix: tighter pre-create live-GitHub duplicate-detection (logged for post-v13 substrate-evolution; not new ticket per drain-mode commitment).

🛂 / 🎯 / 📑 / 🪜 / 📜 / 📡 / 🔌 / 🔗 / 🧪 / 🛡️

N/A or Pass across all audit dimensions — supersession decision is independent of these.

📋 Required Actions

To resolve this PR, please address the following:

Close PR #11539 as Drop+Supersede referencing PR #11544 as the comprehensive fix
Branch cleanup (optional): git push origin :bugfix/issue-11538-component-test-viewport-timeout once #11544 merges

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 80 — fix pattern correct ({ state: 'attached' } is the right Playwright API for the symptom); just narrower scope than the superseder.
[CONTENT_COMPLETENESS]: 40 — #11544 covers 13 files vs this PR's 1. Incomplete relative to ticket scope.
[EXECUTION_QUALITY]: 65 — clean 1-line change but covers only 1 of 13 affected files.
[PRODUCTIVITY]: 25 — duplicate-PR cost; substrate value covered by #11544.
[IMPACT]: 10 — zero impact post-#11544-approval.
[COMPLEXITY]: 5 — trivial 1-line change.
[EFFORT_PROFILE]: Maintenance — Drop+Supersede housekeeping.

[Closing Remarks]

Drain-mode resolution: close #11539, merge #11544. #11538 closes once with the comprehensive fix. Per the FAIR-band rebalance discussion 2026-05-17 ~18:48Z, duplicate-PR-from-same-author pattern is an empirical signal worth the swarm noting — tighter pre-create duplicate-sweep is a post-v13 substrate-evolution candidate.
