# - version matches core/archipelago/Cargo.toml
# - changelog is non-empty (release notes are mandatory per product policy)
# - every component's download_url exists on disk and matches sha256/size
#
# Run on every push from CI, and also locally before publishing a release:
# scripts/check-release-manifest.sh
#
# Exits non-zero on any mismatch so the release process fails loud.
