### Component Architecture

```yaml
components:
  auth_service:
    name: "Authentication Service"
    type: "Microservice"
    technology:
      language: "TypeScript"
      framework: "NestJS"
      runtime: "Node.js 18"


*See sub-skills for full details.*
### Data Architecture (SQL)

```sql
-- Entity Relationship Diagram
-- Users Table
CREATE TABLE users (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    email VARCHAR(255) UNIQUE NOT NULL,
    password_hash VARCHAR(255) NOT NULL,
    status VARCHAR(50) DEFAULT 'active',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,

*See sub-skills for full details.*

## Metrics & Success Criteria

- All components have defined interfaces
- Database schema includes appropriate indexes
- API specification is complete and versioned
- Security architecture covers auth, encryption, compliance
- Scalability plan with measurable triggers
