# System overview

Explains system zones and responsibilities.

### High-Level Architecture

IntelFactor consists of two primary layers:

```mermaid
flowchart LR
  subgraph OT[Zone 1: Production (OT)]
    CAM[Cameras / sensors] --> EDGE[Edge node]
    EDGE --> DET[Inspection + guardrails]
    DET --> EVT[(Local event DB)]
    DET --> EVID[(Local evidence store)]
    DET --> RCA[Local RCA / decision support]
  end

  subgraph SITE[Zone 2: Site data zone (on-prem)]
    HUB[Site hub services]
    HUB --> PG[(Relational DB)]
    HUB --> OBJ[(Object storage)]
    HUB --> DASH[Dashboards]
    HUB --> REG[Model / artifact registry]
  end

  subgraph REMOTE[Zone 3: Remote access (optional)]
    VPN[VPN / jump host]
    OBS[Monitoring / alerts]
  end

  EDGE -. controlled conduit .-> HUB
  VPN -. maintenance only .-> HUB
  HUB --> OBS
```

### Edge Layer

* Captures production signals
* Executes inspection logic
* Classifies outcomes
* Packages evidence
* Emits structured events

### Cloud Layer

* Ingests inspection events
* Stores inspection records
* Provides aggregated analytics
* Supports dashboards and reporting

Each layer has clearly defined responsibilities and failure boundaries.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://intelfactor.gitbook.io/doc/intelfactor-ai/architecture-and-data/system-overview.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
