# C4 Architecture Documentation


## 🔴 AI FIRST Quality Principle

> **Apply the AI FIRST principle: never accept first-pass quality. Minimum 2 iterations. Read all output, improve every section. No shortcuts.**

## Purpose

Document Riksdagsmonitor architecture using C4 model (Context, Container, Component, Code).

## C4 Model Levels

### Level 1: Context Diagram
Shows system in environment with users and external systems.

```mermaid
C4Context
  title System Context - Riksdagsmonitor

  Person(citizen, "Citizen", "Seeks political transparency")
  
  System(riksdag, "Riksdagsmonitor", "Static HTML/CSS website for Swedish Parliament monitoring")
  
  System_Ext(github_pages, "GitHub Pages", "Static site hosting with CDN")
  System_Ext(riksdag_api, "Riksdag-Regering MCP", "Swedish political data API (32 tools)")
  System_Ext(cia, "CIA Platform", "Political intelligence backend")
  
  Rel(citizen, riksdag, "Views political data", "HTTPS")
  Rel(riksdag, github_pages, "Hosted on", "HTTPS, TLS 1.3")
  Rel(riksdag, riksdag_api, "Fetches data via", "HTTP MCP")
  Rel(riksdag, cia, "Links to", "HTTPS")
```

### Level 2: Container Diagram
Shows high-level technology choices.

```mermaid
C4Container
  title Container Diagram - Riksdagsmonitor

  Person(citizen, "Citizen")
  
  Container(web, "Web Application", "HTML5/CSS3", "Static website with 14 languages")
  Container(mcp, "MCP Servers", "Node.js", "riksdag-regering, filesystem, memory, git")
  Container(gh_actions, "GitHub Actions", "CI/CD", "Quality checks, deployment")
  
  ContainerDb(git_repo, "Git Repository", "GitHub", "Version control, content storage")
  
  System_Ext(github_pages, "GitHub Pages")
  System_Ext(riksdag_api, "Riksdagen API")
  
  Rel(citizen, web, "Views", "HTTPS")
  Rel(web, github_pages, "Hosted on")
  Rel(mcp, riksdag_api, "Fetches data")
  Rel(gh_actions, git_repo, "Deploys from")
  Rel(gh_actions, github_pages, "Publishes to")
```

### Level 3: Component Diagram
Shows internal structure.

## Documentation Structure
