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 #15286

The dock reorder journey is green again on plain dev: the seed assert is position-scoped to the drag's real precondition (strategy + swarm adjacent at the head of main-tabs), the release lands at Swarm's center (exactly one sibling midpoint crossed = one deterministic swap on any bar length, replacing the 2-tab-era "+12px past Swarm" overshoot that now sits in Metrics' territory), and the post-drag assert proves the exact single swap — head pair flipped, tail byte-identical to the seed. The example's deliberately-grown 7-item seed (the overflow-pressure scene) stays authoritative and untouched.

Evidence: L3 achieved (real-pointer headless journey against the live example; App-Worker committed-document truth via the neuralLink fixture) → L3 required (AC-1/AC-3). Residual: none.

Deltas from ticket

None substantive — the fix shipped exactly as prescribed. The ticket's contingency (a blocked_by edge to PR #15282 if the 7-tab bar needed the sensor repair) proved unnecessary: the journey passes on plain dev, so this PR is fully independent.

Test Evidence

NEO_E2E_PORT=8096 npx playwright test DockDragDropNL -c test/playwright/playwright.config.e2e.mjs --workers=1 → 1/1 on dev-based head (was: red at the seed assert). Console receipt: ["strategy","swarm","metrics","timeline","agents","alerts","history"] -> ["swarm","strategy","metrics","timeline","agents","alerts","history"].
Touched surface: dashboard dock example journey only (spec-only diff; the example source is untouched). Sibling coverage on the same surface: DockCrossZoneDragNL 1/1 in the same session's sweep.

Post-Merge Validation

None — the spec runs outside CI by design (e2e layer); the local receipt above is the evidence class.

PR Review Summary

Status: Approve

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: A 19-line test-only realignment that repairs the journey's seed-drift class at its root (position-scoping) while making the post-condition STRONGER — first-review-terminal per the graduated economics.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: #15286; the full diff; the PR body's console receipt + run evidence; the drag-family context (D#15204 lineage, #15282 sensor adjacency).
Expected Solution Shape: decouple the journey from the example's evolving tab count without weakening what the drag proves.
Patch Verdict: Matches, and exceeds on the proof side.
Premise Coherence: The seed-drift diagnosis is correct — the old whole-array seed assert + the 2-tab-era "+12px past Swarm" release were both bar-length-coupled.

🔬 Depth Floor

Challenge (the narrowing-change falsifier — does the scoped seed introduce a false negative?): No — verified against the mixed-input matrix: (a) a 3-tab overshoot (strategy past swarm AND metrics) fails slice(0,2) = ['swarm','metrics']; (b) a broader reorder fails the tail-identity assert; (c) a no-op drag fails the head-pair flip. The narrowed seed is paired with a NEW post-assert (tail === seedTail), so net proof strength increases: the old test proved "some reorder happened", this proves "exactly one deterministic swap". The center-release geometry is bar-length-independent by construction (exactly one sibling midpoint crossed) — the right invariant, not a coordinate patch. Findings: none blocking. One pre-existing note, explicitly out of this diff's scope: the waitForTimeout(1000) settle is the fixed-sleep class the whitebox-readiness work targets elsewhere — when a settled-projection helper lands repo-wide, this journey is a natural adoption site.

🪜 Evidence Audit

Evidence: L3 achieved — real-pointer headless journey vs the live example, App-Worker committed-document truth via the neuralLink fixture; 1/1 on the dev-based head with the before→after console receipt reproduced in the body.
The ticket's #15282 contingency correctly proved unnecessary and is documented as such (fully independent PR — no phantom dependency edge).

🧪 Test-Evidence & Location Audit

Canonical e2e tree; spec-only diff; no runtime surface touched. Findings: Pass.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 96 — the invariant (one midpoint = one swap) replaces coordinate coupling.
[CONTENT_COMPLETENESS]: 97 — seed-scope + geometry + exact-swap proof + honest contingency closure.
[EXECUTION_QUALITY]: 97 — 19 lines, stronger proof, clean receipt.
[PRODUCTIVITY]: 95 — unblocks the dock wave's journey gate on plain dev.
[IMPACT]: 85 — the docking demos' e2e gate is a release-sentence item.
[COMPLEXITY]: 95 — appropriately minimal.
[EFFORT_PROFILE]: Quick Win.

Terminal verdict: approved on this exact head. Human merge gate only.
