[Bug] Anthropic API Error: Sonnet 5 Safeguards Incorrectly Blocking Legitimate Game Development Tasks

**Bug Description**
Subject: Suspected false-positive cyber safeguard blocking mobile game development

Claude Code running inside Munder Difflin repeatedly returns:

“Sonnet 5's safeguards flagged this message.”
Details: [cyber]
Request ID: req_011CezPsfqfxGfqubkKPcreS

The requested task is development of a local Phaser/TypeScript mobile puzzle game, Elektrik Ustası: PNG artwork, transparency, tile alignment, visual QA, and gameplay.

Please investigate the identified request and determine whether this is a false-positive classification. The visible error does not identify the triggering content.

Repeated attempts have remained blocked. A previous /feedback screen opened an unrelated, older Chrome-cleanup report, so I am submitting this incident separately.

Please provide the supported remediation for this session.

**Environment Info**
- Platform: darwin
- Terminal: xterm-256color
- Version: 2.1.265
- Feedback ID: dc0c54aa-f2cd-49e2-a065-8c8a062cebba

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

No repository file, test, or entry point is named. Start by reviewing the reported request ID and reproducing the task on Claude Code 2.1.265 on darwin; the investigation is complete when the triggering content or false-positive classification and the supported session remediation are identified.
