# CF-SEC-009 — pin both the mdbook-mermaid version AND the SHA256 of
# the prebuilt tarball. The previous workflow streamed the tarball
# straight into `tar -xz` with no integrity check; a compromised GitHub
# release asset or transit MITM could have executed arbitrary code in
# the docs build job. Keep both jobs in sync via these env vars.
