Bug type

Regression (worked before, now fails)

Summary

Description

When chatting via iMessage, assistant replies are now appearing in BOTH:

1. The original iMessage conversation
2. The Control UI / WebChat interface

This is a regression. Previously, these were independent - Control UI was just a viewer, replies only went to the source channel.

Expected Behavior

• When user messages via iMessage, replies should ONLY go back to iMessage
• Control UI should only display the conversation, not receive duplicate replies

Environment

• OpenClaw version: 2026.3.2
• macOS: 26.3
• Channels: iMessage enabled, Control UI (WebChat)

Configuration

{
  "channels": {
    "imessage": {
      "enabled": true
    }
  },
  "session": {
    "dmScope": "per-channel-peer"
  }
}

### Steps to reproduce

Send a message via iMessage

### Actual behavior

msg duplicate
