      • Retains only pincode (not full address) for regional analysis
    • Added validateAnonymization() function
      • Throws error if PII detected in anonymized data
      • Ensures DPDP Act 2023 compliance
    • Added aggregateSymptomsByRegion() function
      • Aggregates anonymized data for Sentinel Dashboard
