**Bug Description**
i keep running into safeguards when developing a video game that contains violent mechanics, GTA 5 style (FiveM)

**Environment Info**
- Platform: win32
- Terminal: null
- Version: 2.1.229
- Feedback ID: dd788081-ed66-48ec-b5e2-da73a8f7ac0f

**Errors**
```json
[{"error":"TelemetrySafeError: VirtualMessageList: itemKeys/messages length desync (keys=291 messages=290 range=[256,291))\n at cfE (B:/~BUN/root/cli:23349:33082)\n at aGm (B:/~BUN/root/cli:23349:26004)\n at $n (B:/~BUN/root/cli:2273:21349)\n at lc (B:/~BUN/root/cli:2273:40444)\n at ETe (B:/~BUN/root/cli:2273:51368)\n at JV (B:/~BUN/root/cli:2273:89058)\n at Cbe (B:/~BUN/root/cli:2273:88009)\n at kTe (B:/~BUN/root/cli:2273:87830)\n at uL (B:/~BUN/root/cli:2273:84092)\n at ft (B:/~BUN/root/cli:2273:6660)","timestamp":"2026-09-02T19:02:32.362Z"}]
```

The report names no source file, test, or entry point. Start by locating where Claude Code safeguards and policy decisions are handled, then clarify the proposed game-development exception, its boundaries, and a testable acceptance case for violent mechanics.
