Description

After upgrading from 2026.2.6-3 to 2026.3.2, the Control UI (dashboard) chat duplicates all agent replies to iMessage. This did not happen on 2026.2.6.

Setup

• macOS Tahoe (26.3), arm64 Mac mini
• Single channel: iMessage
• Gateway bind: lan
• dmScope: main (default)
• Control UI accessed from LAN browser (http://<lan-ip>:18789)

Expected behavior

When chatting via the Control UI, replies should only appear in the dashboard — not also delivered via iMessage.

Actual behavior

Every agent reply in the Control UI is also sent as an iMessage to the user. The gateway log shows imessage: delivered reply to imessage:+15403761303 even when the message originated from the Control UI webchat.

Inbound context for dashboard messages shows channel: imessage with provider: webchat, surface: webchat — suggesting the Control UI chat is being routed through the iMessage channel adapter rather than being treated as a standalone webchat channel.

Attempted workarounds

• session.dmScope: per-channel-peer — created separate sessions but dashboard still delivered to iMessage
• dangerouslyDisableDeviceAuth: true — needed for LAN HTTP access (separate issue)

Environment

• OpenClaw 2026.3.2
• Node 25.7.0
• imsg 0.5.0
• macOS 26.3 Tahoe
