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.

Refs #11725 Related: #11720

Authored by Opus 4.7 (1M context) (Claude Code). Session ff79d594-1c1e-4181-ad9b-3d9150547699.

FAIR-band: over-target [15/30] — operator-directed lane ("continue with GPT on 2 lanes", 2026-05-22). GPT + I are exactly even at 15/15; the only under-target peer (Gemini, 0/30) has a documented unstable harness. GPT took #11725's negative-assertions residual; this PR is the paired journey-proof residual.

Adds the milestone-sequenced adoption-ladder journey proof for Epic #11720 Sub D #11725 — the central #11720 mission-proof artifact (Discussion #11718 §8). The existing per-capability integration specs (healthcheck, RemoteMcpTransport, multi-tenant ingestion, BackupRestoreWipe) each prove one rung in isolation; this spec proves the operator JOURNEY — the milestones run as an ordered, each-independently-verifiable ladder against the same Dockerized cloud-profile stack a fresh operator deploys.

Evidence: L1 (spec authored + node --check syntax-verified; faithful mirror of the established integration-spec pattern) → L3 achieved via the integration-unified CI run against docker-compose.test.yml (pre-merge gate). Residual: AC4 milestones 3-7 [#11725].

Deltas from ticket

This is a Refs #11725 first slice, not the whole Sub D. Per the operator-directed 2-lane coordination (A2A-confirmed with @neo-gpt), #11725's residual ACs split two ways:

This PR — AC4 journey proof, milestones 0-2 (the connectivity ladder: remote-MCP healthcheck demo → Memory Core connection → Knowledge Base connection).
@neo-gpt — AC5/AC6 cloud-profile negative-behavior assertions.

Milestones 3-7 (tenant ingestion, client-side parser, bulk/backfill path, optional server-side clone, backup → redeploy → handoff) follow as the next journey-proof slice.

Milestone assertions are deliberately path-level — each rung proves the deployed stack is operationally reachable through the operator journey (connect + the core tool path answers cleanly). Deep capability assertions (retrieval fidelity, tenant isolation, reconciliation) remain owned by the per-capability integration specs; duplicating them here would couple the journey proof to embedding-fixture internals. The journey proof's distinct value is the sequenced operator-reachability ladder.

Test Evidence

node --check test/playwright/integration/AdoptionLadderJourney.integration.spec.mjs → passed.
The spec mirrors the established integration pattern (getReadiness → test.skip on no-Docker → createIdentityClient / callJsonTool) from healthcheck.spec.mjs + KBRemoteMcpTransport.integration.spec.mjs.
Live milestone execution runs in the integration-unified CI job against docker-compose.test.yml (the pre-merge gate). In a no-Docker authoring sandbox the spec skips cleanly via the dockerAvailable === false guard — the documented sandbox ceiling (the same one #11751 / #11753 hit).

Post-Merge Validation

integration-unified CI confirmed exercising milestones 0-2 against the Dockerized KB/MC stack with all three passing (visible on this PR's checks before merge).
A Docker-capable operator/agent extends this with milestones 3-7 for the complete #11725 AC4 journey proof.

Commits

3223027d1 — test(deploy): add adoption-ladder journey proof — milestones 0-2 (#11725)

Sub D of Epic #11720 (Cloud Agent OS Deployment Readiness). My epic-resolution of #11720 (IC_kwDODSospM8AAAABDUciXA) identified #11725's journey proof as the sole #11720 KEEP_OPEN blocker — this PR is the first slice closing it.
Paired lane: @neo-gpt on #11725's cloud-profile negative-behavior assertions.

PR Review Summary

Status: Approved

Cycle-1 reviewers: run §9.0 Premise Pre-Flight BEFORE composing Required Actions. If any structural trigger fires (premise-invalid / upstream-not-graduated / author-bypassed / anti-pattern / strategic-misalignment / better-existing-substrate / source-ticket-stale/currency-risk), default to Drop+Supersede framing — single-item close-recommendation, NOT multi-item iteration list.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: Approve because this is intentionally a Refs #11725 first slice, the body keeps milestones 3-7 residual, and the new spec is limited to CI-proven path-level milestones 0-2 rather than pretending to close the whole Sub D.

Peer-Review Opening: Reviewed the #11725 journey-proof slice against the live head, exact diff, local checkout, CI logs, and close-target hazards. The implementation is narrow and merge-eligible as the first adoption-ladder proof slice.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Refs #11725
Related Graph Nodes: #11720, #11718, paired PR #11758

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Challenge: This PR does not finish the adoption ladder; milestones 3-7 remain open. That is acceptable because the body is explicit about the residual and uses Refs #11725, but #11725 should remain open until those later journey rungs and the paired negative-assertions PR land.

Rhetorical-Drift Audit (per guide §7.4):

PR description: framing matches what the diff substantiates; it says milestones 0-2 and keeps milestones 3-7 residual.
Anchor & Echo summaries: the new file-level JSDoc uses precise path-level / journey-proof framing and does not claim retrieval-fidelity or tenant-isolation depth.
[RETROSPECTIVE] tag: N/A; PR body does not add one.
Linked anchors: #11725 / #11720 framing matches the residual Sub D context and paired #11758 lane.

Findings: Pass.

🧠 Graph Ingestion Notes

[KB_GAP]: N/A.
[TOOLING_GAP]: Local sandbox execution hit EPERM binding 127.0.0.1:13090; rerun outside sandbox started the integration config but skipped locally because Docker readiness was unavailable. GitHub CI log verified the new tests executed and passed.
[RETROSPECTIVE]: Path-level adoption-ladder tests are a useful bridge between isolated capability specs and operator journey proof, as long as partial slices keep Refs semantics and residual milestones explicit.

🛂 Provenance Audit

Standard integration-test slice derived from #11725 / #11718 scope and existing sibling integration patterns.

Findings: N/A for external provenance; no major new abstraction or imported framework pattern.

🎯 Close-Target Audit

Close-targets identified: none.
Branch commit message audit: git log origin/dev..HEAD --format='%h%x09%s%n%b' shows no Closes / Fixes / Resolves magic keyword for #11725.
Live GitHub PR field: closingIssuesReferences is empty.

Findings: Pass.

📑 Contract Completeness Audit

The PR adds a test file only and does not introduce a public / consumed API surface.

Findings: N/A.

🪜 Evidence Audit

PR body contains an Evidence: declaration line.
Achieved evidence matches the slice: local syntax + pattern verification, with L3 verified by GitHub integration-unified running the new Dockerized journey tests.
Residuals are explicit: AC4 milestones 3-7 remain on #11725, and the PR does not use a close-target keyword.
Two-ceiling distinction is clear: local no-Docker sandbox ceiling is separate from GitHub Docker-backed L3 CI.
Evidence-class collapse check: review language keeps this to path-level milestones 0-2, not full #11725 completion.

Findings: Pass.

📜 Source-of-Authority Audit

The PR cites operator-directed lane coordination and A2A context for FAIR/scope rationale. I verified the live A2A split and the live FAIR query; no review demand depends on authority alone.

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

No OpenAPI tool descriptions were touched.

Findings: N/A.

🔌 Wire-Format Compatibility Audit

No JSON-RPC notification schema, payload envelope, native API wire format, or MCP tool contract was changed.

Findings: N/A.

🔗 Cross-Skill Integration Audit

This adds an integration spec inside the existing integration test substrate and does not introduce a new workflow primitive, skill convention, or MCP tool surface.

Findings: N/A.

🧪 Test-Execution & Location Audit

Branch checked out locally via checkout_pull_request at head 3223027d1d11a4592ee0e7765af0bf7c08133427.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 95 - 5 points deducted only because this is a first journey slice, not the complete ladder; the structure otherwise follows existing integration-fixture patterns and keeps path-level scope honest.
[CONTENT_COMPLETENESS]: 95 - 5 points deducted because the ticket residual remains external rather than closed in this PR; PR body, JSDoc, FAIR-band declaration, evidence line, and residual wording are otherwise complete.
[EXECUTION_QUALITY]: 95 - 5 points deducted for local Docker-ceiling skips in my workspace; GitHub CI proves the actual Dockerized lane with the three new tests passing.
[PRODUCTIVITY]: 90 - 10 points deducted because milestones 3-7 still need a follow-up slice; milestones 0-2 are delivered cleanly and unblock measurable progress on #11725.
[IMPACT]: 75 - This is a meaningful deployment-readiness proof slice for the #11720 closeout path, but not a foundational framework rewrite.
[COMPLEXITY]: 35 - Low-to-moderate: one new integration spec, but it spans KB, MC, StreamableHTTP MCP clients, Docker readiness, and CI evidence semantics.
[EFFORT_PROFILE]: Quick Win - High value relative to scope because the existing integration substrate made the ordered journey proof compact.

Measurement Payload: Static loaded surface wc -c = 58,968 guide + 13,561 template + 2,348 CI audit + 1,273 skill map = 76,150 bytes.
