[Bug] Fable safeguards causing excessive false positives and forced model switching

**Bug Description**
Your Fable safeguards are buggy as hell. I can not use Fable for any security/cryptography related work, and even in normal work messages are being flagged for nonsense. Those safeguards force a model switch, which does then result in lower quality output as well. That's not useable in any professional environment. That issue has been opened many times by others as well, and then closed because it was ignored. Seriously not good advertising.

**Environment Info**
- Platform: win32
- Terminal: null
- Version: 2.1.270
- Feedback ID: 2712c54b-997f-4780-9f74-5aac13d50e08

● Fable 5.1's safeguards flagged this message. Our intentionally broad safeguards allow us to deliver more capabilities faster, but can sometimes flag
legitimate coding, cybersecurity, and biology tasks. Switched to Opus 5. Send feedback with /feedback or learn more:
