7z

High-compression archive creation with strong compression and encryption support.

Prerequisite Check

Run this before proposing archive work:

command -v 7z >/dev/null 2>&1 || 7z --help

If 7z is missing, surface that immediately and either:

• run scripts/install.sh or scripts/install.ps1
• fall back to unzip for ZIP extraction only
• fall back to tar -xf archive.tar.* for tar-based archives
