Subsequent edits replaced that message's content with only the small post-split tokens, causing the message to visually shrink from ~3800 chars to a few dozen. Fix: at the split threshold, finalize (edit) the current message with its accumulated content, then reset current_msg_id = None so the next batch of tokens creates a fresh message. This eliminates both the content duplication across messages and the dramatic shrinking effect.
