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 #11006

Adds a sibling ai/scripts/orchestrator-daemon.mjs runner for Agent OS maintenance triggers, moves the existing summary sweep out of bridge-daemon.mjs, and schedules Knowledge Base delta sync through the same per-host singleton boundary. The bridge daemon now remains focused on wake delivery only.

Evidence: L2 (static contract checks + unit-validated task wiring + bridge wake regression suite with spawned daemon fixtures) -> L2 required (MVP ownership split and existing-script orchestration). No residual ticket ACs.

Deltas from ticket

Keeps NEO_SUMMARIZATION_SWEEP_INTERVAL_MS as a compatibility alias while adding NEO_ORCHESTRATOR_SUMMARY_SWEEP_INTERVAL_MS.
Adds NEO_ORCHESTRATOR_KB_SYNC_INTERVAL_MS and NEO_ORCHESTRATOR_POLL_INTERVAL_MS.
Adds an M3 MVP split note to learn/agentos/v13-path.md; the full Neo ai/daemons/Orchestrator.mjs class and healthcheck surface remain future M3 completion work.

Slot Rationale

Added M3 MVP split note in learn/agentos/v13-path.md: disposition keep until the full M3 orchestrator class lands, then rewrite or retire into milestone history. 3-axis rating: trigger-frequency low, failure-severity medium, enforceability low. Future-decay mitigation: the paragraph names #11006 as an MVP bridge and explicitly preserves the later full-Orchestrator completion target, so it should not accrete into a permanent duplicate roadmap layer.

Test Evidence

node --check ai/scripts/orchestrator-daemon.mjs
node --check ai/scripts/bridge-daemon.mjs
git diff --check
rg -n "Piece C|summarize-sessions|summarization.pid|NEO_SUMMARIZATION_SWEEP_INTERVAL_MS|checkSummarizationLifecycle|getUnreadSunsetHandovers|markNodesAsRead" ai/scripts/bridge-daemon.mjs ai/scripts/orchestrator-daemon.mjs package.json test/playwright/unit/ai/scripts learn/agentos/v13-path.md
npm run test-unit -- test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs test/playwright/unit/ai/scripts/bridge-daemon-queries.spec.mjs — 10 passed.
npm run test-unit -- --workers=1 test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs test/playwright/unit/ai/scripts/bridge-daemon-queries.spec.mjs test/playwright/unit/ai/scripts/bridge-daemon.spec.mjs — 23 passed. Ran outside the sandbox because this checkout's .neo-ai-data/sqlite is a symlink to the shared Git checkout path.

Post-Merge Validation

Restart the bridge daemon and confirm it no longer logs Triggering Piece C periodic summarization sweep.
Start npm run ai:orchestrator on the operator host and confirm .neo-ai-data/orchestrator-daemon/orchestrator.log records summary and KB sync task ownership.
Optionally use short NEO_ORCHESTRATOR_SUMMARY_SWEEP_INTERVAL_MS / NEO_ORCHESTRATOR_KB_SYNC_INTERVAL_MS values once to confirm cadence behavior without waiting for default intervals.

Input from Gemini 3.1 Pro (Antigravity):

✦ # PR Review Summary

Status: Comment (Pending CI)

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve+Follow-Up

Rationale: Splitting the orchestrator maintenance daemon from the bridge daemon fulfills the MVP scope of #11006. The code correctly shells out to the existing scripts instead of reimplementing them, keeping the diff lean.

Peer-Review Opening: Solid MVP slice for the Orchestrator daemon. Moving the summary and KB sync triggers out of the bridge daemon strictly isolates their lifecycle concerns. The test coverage for the interval parsing and task mapping looks robust. I've left the formal evaluation below and will hold final approval until CI goes green.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #11006

🔬 Depth Floor

Documented search: I reviewed the new daemon script and its unit tests. The fallback logic for handling interval 0 is properly tested, and the buildTaskDefinitions map provides a clean extension point for future tasks.

Rhetorical-Drift Audit (per guide §7.4):

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

Anchor & Echo summaries: precise codebase terminology

[RETROSPECTIVE] tag: accurately characterizes what shipped

Linked anchors: cited tickets/PRs actually establish the claimed pattern

Findings: Pass. The MVP limitation is explicitly documented in the PR body and the v13-path.md file.

🧠 Graph Ingestion Notes

[RETROSPECTIVE]: The Agent OS architecture now divides daemon responsibilities: bridge-daemon strictly handles wake-event delivery, while orchestrator-daemon handles scheduled maintenance tasks like KB sync and session summarization.
