[Billing / Go Plan] Abnormal high-frequency deduction on qwen3.7-max under Go subscription #36399

Description

Hi team,

I am a paid OpenCode Go subscriber experiencing unexpected billing issues with qwen3.7-max.

Environment

• OS: Ubuntu 24.04
• Client: OpenCode CLI (Latest)
• Plan: Go ($60/month)

Observed Behavior
Since July 8th, I see continuous calls every 30 minutes. Each costs ~$0.20.

Logs:

Key Anomalies:

1. Frequency: Exact 30-minute intervals (Automated/Cron).
2. Volume: ~64k Input Tokens (Automated Context Injection).
3. Balance: Dropped to ~$2. Possible leak from Zen balance despite "Go" label.

Expected Behavior

1. Go credits should cover usage without touching Zen balance.
2. No idle calls.
3. Clear log separation between Go credits and real balance.

Security Note
API keys rotated. Pattern suggests background agent billing issue.
I have private logs/screenshots ready.

Please advise on stopping this drain and reviewing charges.

Thanks.
