Problem

BlueBubbles group chat messages do not include sender information in the message header/envelope passed to the LLM, making it impossible for the AI to distinguish who is speaking in group chats.

Expected format:

[BlueBubbles GROUP CHAT from 张三 (+8613800138000) Sat 2026-02-14 21:00 GMT+8] message text

Actual format:

[BlueBubbles Sat 2026-02-14 21:00 GMT+8] message text

The [from:] field is completely absent for group messages.

Root Cause

In monitor-processing.ts (around line 1996-2020), the fromLabel is explicitly set to undefined for group chats:

const fromLabel = isGroup ? undefined : message.senderName || `user:${message.senderId}`;

The sender data (senderId, senderName) exists in the webhook payload but is not included in the formatted message body/envelope.

Impact

• AI agent cannot identify who sent each message in group chats
• Leads to misattribution of messages (e.g., confusing family members)
• Severely degrades group chat experience

Environment

• OpenClaw: 2026.2.12
• BlueBubbles Server: macOS 26.2.0
• Platform: macOS (Apple Silicon)

Suggested Fix

Include sender info in the envelope for group messages, similar to what #336 proposes for Telegram:

const fromLabel = message.senderName || `user:${message.senderId}`;
