[Bug] Session flagged by content filter despite model confidence

**Bug Description**
I did what I can try to test our companies' service using interner product and aws infra. Fable 5.1 flagged my session but, it is not something the model doubt. still the sensoring coverage is broad.

**Environment Info**
- Platform: darwin
- Terminal: Orca
- Version: 2.1.258
- Feedback ID: 29271b1b-8e9d-4f7e-a22f-f429f17a7194

**Errors**
```json
[]
```

Start with feedback ID 29271b1b-8e9d-4f7e-a22f-f429f17a7194 and reproduce the report on darwin with Orca 2.1.258, using the described service and AWS setup. No source file, test, or precise triggering session is identified; done requires a confirmed explanation or reproducible fix for the session being flagged despite the reported model confidence.
