#!/usr/bin/env python3 """End-to-end pack integrity test. Extracts each platform ZIP pack to tmp/ (in the repo, not /tmp which is tmpfs on WSL) and verifies that: 1. The archive is not corrupt and fully decompressable 2. Every file declared in the platform YAML exists at the correct path 3. Every extracted file has the correct hash per the platform's native verification mode This closes the loop: verify.py checks source bios/ -> this script checks the final delivered ZIP the user actually downloads.
