Summary

Before OpenClaw 2026.4.2, Zalo webhook replay dedupe keys were not scoped strongly enough across chat and sender dimensions. Legitimate events from different conversations or senders could collide and be dropped as duplicates.

Impact

Cross-conversation or cross-sender collisions could cause silent message suppression and break bot workflows. This was an availability issue in webhook event processing.
