7/// The release's `SHA256SUMS.minisig` must verify against a minisign key this
8/// build embeds, and the archive must match the signed manifest, before any
9/// byte of the running binary changes. Only a binary the user can write and
10/// that `cargo install` did not place is replaced; the command names the path
11/// and the reason otherwise.
