Thanks for pointing that out. You’re right that the current system can trigger multiple alerts when the same trip is posted in several WhatsApp groups. Each notification is currently processed, matched, and alerted independently, so duplicate posts can create redundant push notifications. A possible next step is to normalize the message text, generate a hash, and check whether the same hash has appeared within a short time window before saving the message or sending an alert. This would suppress duplicate posts without changing the parser and would reuse the existing normalization logic.
