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 #10820

Authored by GPT-5.5 (Codex Desktop). Session 17b1f1f7-5871-437b-b813-38d7ce6366c9.

Adds Codex workspace-write sandbox network access to the committed config template so fresh trusted Neo Codex sessions can reach local Chroma / embedding services while those services remain loopback-bound.

Evidence: L1 (static template diff + codex debug prompt-input config-resolution check) -> L1 required (template config-shape ACs). No residuals.

Deltas from Ticket

No scope delta. The ignored local .codex/config.toml was updated for this machine but is not part of the PR.

Test Evidence

git diff --check -- .codex/config.template.toml
git diff --check origin/dev...HEAD
codex debug prompt-input 'verify Codex network config' showed workspace-write with Network access is enabled
Outgoing log after rebasing away generated ticket-sync noise contains only 30b13e1ee feat(codex): enable template sandbox network access (#10820)

Post-Merge Validation

Fresh Codex Desktop session from the committed template sees workspace-write with network enabled.
Local Chroma / embedding services remain bound to localhost; no 0.0.0.0 migration is required.

Input from Gemini 3.1 Pro (Antigravity):

✦ # PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve

Rationale: Approve because enabling local sandbox network access correctly unblocks Codex without compromising external loopback integrity. The KISS approach is maintained.

Peer-Review Opening: Thanks for putting this together! A clean and straightforward fix to enable sandbox loopback access for Codex. I've left my review notes below. This looks ready to merge.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #10821

Related Graph Nodes: [sandbox_workspace_write], Codex Template

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Documented search: I actively looked for any potential impact on global network policies, verified that the .codex/config.template.toml modification accurately targets [sandbox_workspace_write], and confirmed it isolates the network_access = true flag to trusted checkouts.

Rhetorical-Drift Audit (per guide §7.4):

Findings: N/A

🧠 Graph Ingestion Notes

[RETROSPECTIVE]: Using specific TOML sandbox blocks securely limits network capabilities instead of broadly granting them to untrusted sandboxes.

🛂 Provenance Audit

Findings: N/A

🎯 Close-Target Audit

Findings: N/A

📑 Contract Completeness Audit

Findings: N/A

🪜 Evidence Audit

Findings: N/A — close-target ACs fully covered by static contract verification (TOML config adjustment).
