 # 02 — Architecture Constraints
 
-Status: skeleton
+## Technical Constraints
 
-Document imposed constraints: technical, organizational, regulatory, and environmental constraints that affect architecture decisions.
+> e.g., choice of FastAPI, PostgreSQL, SQLAlchemy, Chart.js, Jinja2 templates.
+
+## Organizational Constraints
+
+> e.g., team skillsets, development workflows, CI/CD pipelines.
+
+## Regulatory Constraints
+
+> e.g., data privacy laws, industry standards.
+
+## Environmental Constraints
+
+> e.g., deployment environments, cloud provider limitations.
+
+## Performance Constraints
+
+> e.g., response time requirements, scalability needs.
+
+## Security Constraints
+
+> e.g., authentication mechanisms, data encryption standards.
+
+## Budgetary Constraints
+
+> e.g., licensing costs, infrastructure budgets.
+
+## Time Constraints
+
+> e.g., project deadlines, release schedules.
+
+## Interoperability Constraints
+
+> e.g., integration with existing systems, third-party services.
+
+## Maintainability Constraints
+
+> e.g., code modularity, documentation standards.
+
+## Usability Constraints
+
+> e.g., user interface design principles, accessibility requirements.
+
+## Data Constraints
+
+> e.g., data storage formats, data retention policies.
+
+## Deployment Constraints
+
+> e.g., deployment environments, cloud provider limitations.
+
+## Testing Constraints
+
+> e.g., testing frameworks, test coverage requirements.
+
+## Localization Constraints
+
+> e.g., multi-language support, regional settings.
+
+## Versioning Constraints
+
+> e.g., API versioning strategies, backward compatibility.
+
+## Monitoring Constraints
+
+> e.g., logging standards, performance monitoring tools.
+
+## Backup and Recovery Constraints
+
+> e.g., data backup frequency, disaster recovery plans.
+
+## Development Constraints
+
+> e.g., coding languages, frameworks, libraries to be used or avoided.
+
+## Collaboration Constraints
+
+> e.g., communication tools, collaboration platforms.
+
+## Documentation Constraints
+
+> e.g., documentation tools, style guides.
+
+## Training Constraints
+
+> e.g., training programs, skill development initiatives.
+
+## Support Constraints
+
+> e.g., support channels, response time expectations.
+
+## Legal Constraints
+
+> e.g., compliance requirements, intellectual property considerations.
+
+## Ethical Constraints
+
+> e.g., ethical considerations in data usage, user privacy.
+
+## Environmental Impact Constraints
+
+> e.g., energy consumption considerations, sustainability goals.
+
+## Innovation Constraints
+
+> e.g., limitations on adopting new technologies, risk tolerance for experimentation.
+
+## Cultural Constraints
+
+> e.g., organizational culture, team dynamics affecting development practices.
+
+## Stakeholder Constraints
+
+> e.g., stakeholder expectations, communication preferences.
+
+## Change Management Constraints
+
+> e.g., processes for handling changes, version control practices.
+
+## Resource Constraints
+
+> e.g., availability of hardware, software, and human resources.
+
+## Process Constraints
+
+> e.g., development methodologies (Agile, Scrum), project management tools.
+
+## Quality Constraints
+
+> e.g., code quality standards, testing requirements.
