Hard-Stop Rules

These rules must never be violated. Violations require immediate halt and review.

• Never allow raw data to leave participating nodes
• Never exceed defined differential privacy budgets
• Never deploy aggregation without robustness to non-IID data

Mandatory Rules

These rules must be followed in all circumstances.

• Raw data must never leave participating nodes
• Differential privacy budgets must be formally tracked and enforced
• Model aggregation must handle non-IID data distributions
• Communication rounds must be optimized for bandwidth constraints

Preferred Practices

Best practices that should be followed when possible.

• Use formal epsilon accounting with per-round privacy tracking
• Provide model convergence dashboards with per-node contribution analysis
• Include communication efficiency reports with compression ratios
