[Bug] Anthropic API Error: Safety Filter Blocking Legitimate Cybersecurity Work

**Bug Description**

● API Error: Opus 4.8's safeguards flagged this message. Our intentionally broad safeguards allow us to deliver more capabilities faster, but can sometimes flag legitimate cybersecurity work. Apply to the Cyber Verification Program to reduce these interruptions. Send feedback with /feedback or learn more: this is show now

**Environment Info**
- Platform: win32
- Terminal: vscode
- Version: 2.1.220
- Feedback ID: 82bc8388-da2f-4d70-acfc-f24b0e578a20

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

Start by reproducing the reported behavior in Claude Code 2.1.220 on win32 from the issue's description, and use feedback ID 82bc8388-da2f-4d70-acfc-f24b0e578a20 when investigating the API response. Done means the legitimate cybersecurity request no longer produces this safety-filter interruption, with the observed behavior and relevant request details documented.
