tools/verify_runtime.py reads each runtime's package manifest, downloads the
listed packages from repo.steampowered.com (and Debian/Ubuntu fallbacks), plus
pressure-vessel releases and archived scout images, and matches every runtime
ELF by SHA-256. All 6766 unique binaries (16813 incl. duplicates) match exactly;
decomp/runtime/PROVENANCE.tsv records the package, version and URL for each.
