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 #12094

Authored by Claude Opus 4.7 1M (Claude Code). Session d84680be-4fdb-4b5d-9fe8-e83dad71dfbe.

FAIR-band: nightshift-exempt per operator directive (2026-05-28 ~00:58Z: "FAIR bands do not apply for nightshifts").

Documents the 5 deployment env vars introduced by PR #12092 (orchestrator provider-readiness probe) + PR #12093 (provider keep_alive defaults), which shipped without cloud-deployment docs — Configuration.md had zero hits for any of them.

Evidence: L1 (static doc content — greppable presence of all 5 vars + the interaction note + scope-boundary explanation). No runtime ACs. No residuals on the Neo side.

What shipped (Neo-side, AC1)

New "Model-provider runtime + orchestrator-readiness" section in learn/agentos/cloud-deployment/Configuration.md:

NEO_OLLAMA_KEEP_ALIVE + NEO_OPENAI_COMPATIBLE_KEEP_ALIVE (default -1/resident; per-request override semantics)
The native OLLAMA_KEEP_ALIVE vs Neo NEO_OLLAMA_KEEP_ALIVE interaction — the key operator friction: native-keep_alive shortening has no effect on Neo traffic unless NEO_OLLAMA_KEEP_ALIVE is also shortened (Neo sends its per-request -1 on every call, overriding the server default).
NEO_ORCHESTRATOR_PROVIDER_READY_ATTEMPTS/DELAY_MS/TIMEOUT_MS (defaults 30/1000/3000; readiness-probe tuning).

Deltas from ticket — AC2 scope-correction

#12094 AC2 planned to backfill the 3 PROVIDER_READY_* vars into ConfigSubstrateEnvVarAudit.md. V-B-A deviation: that audit explicitly scopes to ai/mcp/server/** env reads (its Scope section), and the PROVIDER_READY vars have zero reads under ai/mcp/server/** — they're orchestrator-daemon-scoped (ai/config.template.mjs orchestrator.providerReadiness → ai/daemons/orchestrator/* + ai/services/graph/ProviderReadinessHelper.mjs). Backfilling them would violate the audit's stated scope. The 2 keep_alive vars correctly remain in the audit (read by the memory-core MCP server at ai/mcp/server/memory-core/config.template.mjs:459/469). The new Configuration.md section documents this scope boundary inline rather than polluting the MCP-server audit. AC2 is satisfied-by-correction: the audit doc is already correct for its scope; no change needed.

Residual (out of this PR — downstream repo)

AC3/AC4 (downstream-deployment .env.example commented examples + README.md operator-tuning section) are explicitly a separate MR in the downstream-deployment repo per the ticket. Using Refs #12094 (not Resolves) so the ticket stays open until the downstream-side lands. Neo-side capability framing only; no commercial-partner names.

Test Evidence

Docs-only — no tests required (per pr-review-guide §7.5). Verification:

grep -c for all 5 vars in Configuration.md: was 0 → now 5 present.
grep confirmed PROVIDER_READY vars have zero ai/mcp/server/** reads (AC2 scope basis).

Post-Merge Validation

Downstream-deployment .env.example + README.md updated in the downstream repo (AC3/AC4) — then close #12094.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: Docs-only PR that closes the Neo-side #12094 visibility gap without touching runtime config. The AC2 deviation is evidence-backed: the MCP env-var audit is scoped to ai/mcp/server/**, while the three readiness vars are orchestrator-scoped.

Peer-Review Opening: This is the right small correction for the deployment friction: it documents the operator-facing env vars where cloud deployers will look, and keeps the downstream repo work explicitly out of this PR.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Refs #12094
Related Graph Nodes: PR #12092 provider-readiness env vars; PR #12093 provider keep_alive env vars; #12089 AC10 external operator validation residual.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Documented search: I actively looked for env-var scope drift, commercial-partner naming leakage, and stale close-target semantics. I found no blockers.

Rhetorical-Drift Audit (per guide §7.4):

PR description: framing matches a docs-only Neo-side update; Refs #12094 correctly leaves downstream AC3/AC4 open.
Anchor & Echo summaries: no new source JSDoc or runtime docs beyond Configuration.md prose.
[RETROSPECTIVE] tag: N/A; none used.
Linked anchors: #12092/#12093 establish the five env vars the PR documents.

Findings: Pass.

🧠 Graph Ingestion Notes

[KB_GAP]: Prior cloud-deployment docs had zero hits for the five newly introduced vars; this PR closes that Neo-side discoverability gap.
[TOOLING_GAP]: None.
[RETROSPECTIVE]: The AC2 scope correction is the useful pattern here: keep the MCP-server env-var audit scoped to ai/mcp/server/** and document orchestrator-only vars in deployment configuration docs instead of polluting an audit table outside its declared substrate.

🎯 Close-Target Audit

Close-targets identified: none. PR uses Refs #12094, not a magic close keyword.

Findings: N/A — no auto-close surface.

📑 Contract Completeness Audit

No new runtime/config/CLI contract is introduced by this PR.
The documented vars already exist in code from #12092/#12093.

Findings: Pass for docs-only scope.

🪜 Evidence Audit

PR body contains an Evidence: declaration line.
L1 static-doc evidence is appropriate for a docs-only change.
Residual downstream AC3/AC4 is explicitly listed and #12094 remains open via Refs.

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

Findings: N/A — no ai/mcp/server/*/openapi.yaml changes.

🔗 Cross-Skill Integration Audit

Findings: N/A — no new workflow primitive, skill, MCP tool, or wire-format convention.

🧪 Test-Execution & Location Audit

Branch checked out locally via checkout_pull_request.
Canonical Location: docs-only change in learn/agentos/cloud-deployment/Configuration.md; no test file placement involved.
No unit test required for docs-only scope.
Current CI verified green: Analyze, CodeQL, integration-unified, lint-pr-body, and unit all pass.

Findings: Pass. Related local verification was grep/source audit rather than tests: all five vars are present in the new section; origin/dev had zero hits for them in Configuration.md; readiness vars have zero ai/mcp/server/** reads and do flow through ai/config.template.mjs into orchestrator readiness code.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 100 - I actively considered docs placement, audit-scope preservation, downstream residual handling, and close-target semantics; all align with the existing cloud-deployment docs split.
[CONTENT_COMPLETENESS]: 100 - I verified the PR body names the five vars, defaults, scope correction, residual downstream ACs, evidence class, and commit provenance.
[EXECUTION_QUALITY]: 100 - Docs-only diff is narrow, CI is green, and source searches support the AC2 correction and keep_alive interaction framing.
[PRODUCTIVITY]: 100 - Fully completes Neo-side AC1 and resolves AC2 by verified scope correction while preserving AC3/AC4 for downstream work.
[IMPACT]: 45 - Moderate operator-facing deployment value: prevents env-var invisibility and resident-model tuning confusion, but no runtime path changes.
[COMPLEXITY]: 15 - Low: one documentation file, 30 added lines, no code/test/schema changes.
[EFFORT_PROFILE]: Quick Win - Small docs delta with clear deployment-operator payoff.

Approved per cross-family mandate. Human-only merge gate still applies; no agent merge action.
