# Release Verifier

Every hour, polls a release feed and base64-decodes the published checksum from the
response, then verifies the previously downloaded artifact against it via a fixed,
hardcoded `sha256sum --check` invocation — a security-positive integrity check, not
code execution of the decoded value. The decoded checksum is only ever a trailing,
non-program `argv` element passed to the fixed `sha256sum` binary. Runs
`scripts/verify.py`.
