Bug Description

In OpenClaw v2026.3.31, Cron scheduled tasks execute successfully but QQ Bot delivery fails.

Reproduction Steps

1. Create a Cron job with delivery configured to qqbot channel
2. Run task: \openclaw cron run \
3. Task executes successfully, logs show \delivered: true\
4. But no QQ push notification received

Expected Behavior

After Cron task execution succeeds, it should automatically push to the configured QQ session.

Actual Behavior

• Logs show: \delivered: true, \deliveryStatus: delivered\
• No push notification actually received
• Manual \sessions_send\ works correctly

Environment

• OpenClaw Version: 2026.3.31
• OS: Windows 10.0.26200
• Node.js: 24.14.0
• Channel: QQ Bot (configured correctly, manual delivery works)

Possible Cause

Version 3.31 introduced unified Background Tasks system, delivery logic may have changed.

Workaround

1. Use Heartbeat instead of Cron (executes in main session, delivery works)
2. Manual push
