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 #10587

Adds a durable diagnostics path for the explicit Sandman operator flow when the configured OpenAI-compatible / MLX provider never becomes reachable. runSandman.mjs now exposes test seams for provider readiness, records a structured provider-timeout breadcrumb through the Memory Core logger, flushes that file sink before nonzero exit, and remains import-safe for unit coverage.

Deltas from ticket

The durable breadcrumb currently lands in the existing Memory Core always-on log file, not a new Graph node or MCP tool. That keeps the slice intentionally narrow and aligned with #10580/#10583 logger observability while preserving room for later graph-level diagnostics if repeated Sandman failure classes justify it.

Test Evidence

git diff --check
npm run test-unit -- test/playwright/unit/buildScripts/ai/runSandman.spec.mjs test/playwright/unit/ai/mcp/server/memory-core/logger.spec.mjs — 4 passed

Post-Merge Validation

Temporarily point NEO_OPENAI_COMPATIBLE_HOST at an unavailable local endpoint and run npm run ai:run-sandman; verify it exits nonzero and .neo-ai-data/logs/mc-server-<date>.log contains runSandman.provider_readiness_timeout with provider host/model metadata.

✦ # PR Review Summary

Status: Approved

Peer-Review Opening: Thanks for putting this together! Great approach to capturing the hard-fail state durably and adding clear test coverage without needing the actual provider.

Target Epic / Issue ID: Resolves #10587

Related Graph Nodes: runSandman, logger

🔬 Depth Floor

Documented search: I actively looked for the proper test coverage, correct exit status semantics, and ensuring the secret API keys are not leaked in the log breadcrumbs, and found no concerns. The tests correctly assert the log line doesn't contain must-not-be-logged.

🧠 Graph Ingestion Notes

[RETROSPECTIVE]: The addition of logger.flush() is a highly valuable micro-pattern for short-lived operator scripts within the swarm, ensuring durable logs even on hard process exits without breaking long-lived MCP server ergonomics.

Input from Gemini 3.1 Pro (Antigravity):

✦ Status: Approved

Review Synthesis: This PR effectively addresses the Sandman observability gap. By introducing logger.flush(), it ensures that short-lived scripts can durably record hard-fail diagnostics into the Memory Core log stream before exiting. The refactoring of the provider check logic exposes clear test seams without polluting the execution path. Most importantly, the createProviderFailureDiagnostic structure explicitly prevents API key leaks while capturing all necessary topology details (host, model, elapsed time).

Test Coverage: The new Playwright tests successfully validate the timeout loop and ensure the diagnostic payload is sanitized and correctly persisted.

LGTM to merge.
