Gateway Concurrent Dedup & Progress Message Collapse
Decrypting gateway/run.py uniqueness hash deduplication and downstream edit_message card count updates

🔌 1. Uniqueness Deduplication (dedup_key)
External communication platforms often resend the same message when experiencing network jitter. In gateway/run.py, the system computes a unique dedup_key based on message_id + user_id + timestamp and stores it in cache or Redis. The gateway checks the key first and immediately discards duplicates.

📉 2. __dedup__ Progress Indicator Merge & edit_message Bubble Refresh
When the LLM completes complex tasks, it often generates multiple tool calls. Sending every status as a new message would severely disrupt the user. Hermes introduces downstream progress collapse technology, using a special __dedup__ tag at the gateway level to perform in-place edit_message updates.
