🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Server hardening guide covering SSH lockdown, UFW firewall, Fail2ban, and Tailscale VPN; curl-pipe-sh is used only for the official Tailscale installer which is the standard documented installation method, not a covert execution.

⚠ Flagged for review — coarse, uncorroborated signal, not a confirmed exploit. Review the config yourself before installing.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.
