**Bug Description**
Continued flagging of [cyber] with Fable 5.1, despite just doing normal Quest/PICO app development tasks

**Environment Info**
- Platform: win32
- Terminal: visualstudio
- Version: 2.1.261
- Feedback ID: a08fb504-abcf-46d5-8874-d633331b16d6

**Errors**
```json
[{"error":"TelemetrySafeError: VirtualMessageList: itemKeys/messages length desync (keys=474 messages=473 range=[417,474))\n at mQt (B:/~BUN/root/chunk-bab5vngb.js:36:27375)\n at hhe (B:/~BUN/root/chunk-bab5vngb.js:36:20207)\n at Br (B:/~BUN/root/chunk-3fchm6tx.js:18:20178)\n at zu (B:/~BUN/root/chunk-3fchm6tx.js:18:38344)\n at Ih (B:/~BUN/root/chunk-3fchm6tx.js:18:84425)\n at Wg (B:/~BUN/root/chunk-3fchm6tx.js:18:83425)\n at ic (B:/~BUN/root/chunk-3fchm6tx.js:18:83254)\n at jh (B:/~BUN/root/chunk-3fchm6tx.js:18:79779)\n at qe (B:/~BUN/root/chunk-3fchm6tx.js:18:6261)\n at ke (B:/~BUN/root/chunk-3fchm6tx.js:18:4792)","timestamp":"2026-09-05T21:48:16.440Z"}]
```

Start by reproducing the normal Quest/PICO development workflow on win32 with Visual Studio, then inspect the feedback ID and the reported stack trace in chunk-bab5vngb.js and chunk-3fchm6tx.js. Done means legitimate development no longer triggers the cyber safety flag and the VirtualMessageList keys and messages remain synchronized.
