I build systems
that make complex
things feel simple.

// Biological plausibility limits check
export function validateObservation(obs: RawObservation): ValidationResult {
  const bounds = PLAUSIBILITY_BOUNDS[obs.loinc_code];
  if (bounds && obs.value_numeric !== null) {
    if (obs.value_numeric < bounds.min || obs.value_numeric > bounds.max) {
      return {
        severity: "CRITICAL_PLAUSIBILITY_BREACH",
        message: `Value ${obs.value_numeric} outside physiological limits (${bounds.min}-${bounds.max})`
      };
    }
  }
  return { severity: "PASS", message: "Valid" };
}
