 The binary is downloaded straight from the matching `bws-<arch>-unknown-linux-musl-<version>.zip` GitHub release asset, its SHA-256 checksum verified against Bitwarden's own published checksums file, then extracted to `/usr/local/bin/bws`. The musl build is used (statically linked) so it runs regardless of the base image's libc.
 
 Supported architectures: `x86_64` and `aarch64`/`arm64` (e.g. Oracle Cloud Ampere A1). This feature only ever runs inside the Linux container being built — never on the host — so unlike `bws`'s own multi-OS releases, there's no Darwin/Windows case to detect here.
