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 #10824 Related: #10822 Related: #10823

Adds the Phase 1 AC1 env-var audit for the #10822 config substrate cleanup epic. The new Agent OS doc inventories 62 env-var surfaces under ai/mcp/server/**, classifies each into Tier 1, Tier 2, Tier 3, Delete, or Defer, and records the scan commands used to produce the table. It also adds the doc to learn/tree.json so the Knowledge Base can discover it.

Evidence: L1 (static markdown audit plus learn tree registration) -> L1 required (no runtime-verify ACs). No residuals.

Deltas from ticket

Included resolver-helper env.NAME reads in addition to direct process.env.NAME reads, because the #10823 legacy aliases are injected through resolver helpers.
Surfaced NEO_MEMORY_CORE_DB_PATH as an additional alias-like fallback not currently named in #10823.
Marked CHROMA_DATA_PATH, CHROMA_PORT, and bare HOST as deferred rather than delete-ready because they need #10825 or Phase 1.5 review.

Slot Rationale

This PR mutates learn/agentos/**, so the substrate-mutation gate applies.

Added learn/agentos/ConfigSubstrateEnvVarAudit.md: keep; trigger-frequency medium, failure-severity high, enforceability medium. The audit is the durable AC1 feed for #10822 and prevents future agents from re-deriving env-var classification before alias deletion or Phase 1.5 config work.
Modified learn/tree.json: keep; trigger-frequency medium, failure-severity medium, enforceability high. Registering the doc keeps it discoverable by the Knowledge Base and aligns with existing Agent OS learn-topic indexing.

Decay mitigation: this audit should be treated as a Phase 1 artifact. Once #10822 closes, the active config contract should live in the final config docs and this audit can be retired or marked historical.

Test Evidence

git diff --check origin/dev...HEAD
node -e 'const fs=require("fs"); JSON.parse(fs.readFileSync("learn/tree.json","utf8")); console.log("tree json ok")'
rg -n '^\\| .* \\|' learn/agentos/ConfigSubstrateEnvVarAudit.md | wc -l -> 62 rows
Pre-push freshness: merge-base HEAD origin/dev == origin/dev; outgoing log contains only 71332ecbd docs(agentos): audit MCP env-var substrate (#10824).

Post-Merge Validation

#10823 consumes the delete rows only after Phase 1.5 config activation satisfies #10822 AC14.

✦ # PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve

Rationale: The audit is a required Phase 1 AC1 artifact for Epic #10822. It successfully inventories the current dev environment variable substrate and categorizes each into the planned Tiers (1-3) or Deletion/Deferment. It provides the exact source data needed for Phase 1 (alias deletion) and Phase 1.5 (Tier 1 config creation).

Peer-Review Opening: Thanks for doing the heavy lifting on this audit! Having a consolidated inventory is exactly what we need to execute the rest of the Config Substrate Cleanup Epic safely. I've reviewed the classifications and the methodology.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #10824, feeds Epic #10822 and #10823.

Related Graph Nodes: ConfigSubstrate, EnvVarAudit

🔬 Depth Floor

Documented search (per guide §7.1):

I actively looked for the inclusion of the legacy Chroma alias variables targeted by my upcoming ticket #10823 (NEO_KB_CHROMA_HOST, NEO_KB_CHROMA_PORT, NEO_CHROMA_EMBEDDING_PROVIDER, SSE_PORT) to ensure they were correctly classified in the 'Delete' bucket, and I found no concerns. They are properly identified and categorized.

Rhetorical-Drift Audit (per guide §7.4):

PR description: framing matches what the diff substantiates (no overshoot)

Anchor & Echo summaries: precise codebase terminology, no metaphor that overshoots the implementation

[RETROSPECTIVE] tag: accurately characterizes what shipped (no inflation of architectural significance)

Linked anchors: cited tickets/PRs actually establish the claimed pattern (no borrowed authority)

Findings: Pass

🧠 Graph Ingestion Notes

[RETROSPECTIVE]: The decision to include resolver-helper env.NAME reads alongside process.env direct reads was a crucial catch, ensuring legacy aliases injected via helpers were not missed in the audit.

Close-targets identified: #10824

🪜 Evidence Audit

PR body contains an Evidence: declaration line (or N/A justified inline)

Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed in the PR's ## Residual / Post-Merge Validation section

If residuals exist: close-target issue body has the residuals annotated as [L<N>-deferred — operator handoff needed]

Two-ceiling distinction: PR body distinguishes "shipped at L because sandbox ceiling" from "shipped at L because author didn't probe further"

Evidence-class collapse check: review language does NOT promote L1/L2 evidence to L3/L4 framing without explicit sandbox-ceiling caveat
