# ResNet AI Model Constitution

## Core Principles

### Code Quality and Modularity
All code must follow PEP 8 standards, include type hints, comprehensive docstrings, and be organized into modular, reusable components. Rationale: Enhances readability, maintainability, and collaboration in complex AI projects.

### Rigorous Testing Standards
Implement unit tests for all utility functions, integration tests for data pipelines, and model validation tests including cross-validation and performance benchmarks. Use pytest or equivalent frameworks. Rationale: Ensures reliability and catches errors early in AI model development where failures can have significant impacts.

### Reproducibility and Versioning
Version all code, data, and models using Git and DVC. Set random seeds for reproducibility in experiments. Document all dependencies and environments. Rationale: Critical for scientific validation and debugging in machine learning.

### Model Evaluation and Validation
Evaluate models on independent test sets with multiple metrics (accuracy, F1-score, AUC, etc.). Perform error analysis and bias checks. Rationale: Prevents overfitting and ensures models are fair and effective.

### Continuous Integration and Quality Gates
All changes must pass linting, unit tests, and integration tests in CI/CD pipelines. Model performance regressions must be flagged. Rationale: Maintains code and model quality over time.

## Additional Standards

Security: Protect sensitive data, comply with privacy regulations. Ethics: Conduct bias audits, ensure responsible AI practices. Performance: Optimize for computational efficiency and scalability.

## Development Workflow

Code reviews mandatory for all PRs. Model changes require peer review of evaluation results. Use issue tracking for bugs and features.

## Governance

Constitution supersedes other practices. Amendments require documentation and approval from project maintainers. Compliance verified in code reviews.
