[Bug] Fable 5.1 generates false security warnings for embedded systems code

**Bug Description**
Fable 5.1 raise false security alarms which is an annoyance. My field is generator-set control and I am doing embedded systems development. This is terrible.

**Environment Info**
- Platform: linux
- Terminal: xterm-256color
- Version: 2.1.263
- Feedback ID: ff6fe4c3-68c2-409e-bf61-cffbec5d26d7

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

The issue names no repository file, test, entry point, or reproducible steps. Start by clarifying what “Fable 5.1” and the reported version refer to, then obtain a minimal example that produces the false security warning; done should mean the warning is no longer incorrectly reported and the behavior is covered by a test.
