CRITICAL: Never use unwrapor(MAXVALUE) or similar fallback methods for type conversions.

Reason: Using unwrapor(MAXVALUE), max(0), unwrapor(0), or similar fallback methods can cause severe issues by silently mapping out-of-range or invalid values to default values, leading to incorrect calculations and potential system failures.

Rule: Always use proper error handling with maperr or explicit match statements for type conversions. Never silently convert invalid values (negative, out-of-range, etc.) to default values.
