The installer creates a scheduled task running as SYSTEM, copies one PowerShell script under Program Files, stores settings and status under ProgramData, and manages one clearly marked block in the Windows hosts file.

The updater accepts an IPv6 endpoint only after the original ZZZ CDN hostname passes certificate verification and returns a valid HTTP partial-content response. It does not install a certificate, proxy, driver, VPN, or background network service.

The release EXE is a small .NET Framework GUI compiled entirely from this repository. The PowerShell scripts and default configuration are embedded as resources; the program does not download executable code. Every release includes a SHA-256 checksum generated during the build.

Please open a GitHub security advisory instead of a public issue when a report contains an exploitable vulnerability or sensitive details.
