macOS Colima Sandbox // Zero Host Fingerprint

Swallow Host Fingerprints. Pass Only /workspace.

When you type claude on your Mac, Blackhole intercepts the launch. Hardware serials, region settings, and SSH keys are swallowed into the singularity — only your current folder slingshots across into an isolated Colima VM.
