OPA, A Real Policy Evaluated
opa on EL 10 from the GitHub release, refused by Ansible's get_url unless its SHA-256 is the one in the per-asset .sha256 OPA publishes, and re-checked with sha256sum -c by the live test, which then evaluates a one-rule Rego v1 policy against a one-line input with opa eval and expects the denial. The binary only; no opa server. Original role, live-tested on Rocky Linux 10.

Documentation
opa
Open Policy Agent opa on EL 10 from the vendor's release, checked against the
published SHA-256, pinned to a version, installed as root's binary
in /usr/local/bin. Original role for EL 10, live-tested with podman on
Rocky Linux 10.
No package worth the name. EL 10 carries no opa, and a
third-party repository is one more key to trust. This role takes the
release from github.com/open-policy-agent/opa, has Ansible's get_url refuse the asset unless
its SHA-256 is the published one, and the live test checks the asset on
disk against the same published value again.
Pinned. opa_version is what gets installed, kept in a directory
of its own so the checksum file and the asset it names stay together. A
newer release is a variable change and a run; the same version is
changed=0.
Proven to run. The live test runs opa eval -f raw data.main.deny -d /tmp/opa/policy.rego -i /tmp/opa/pod.yaml and expects
"no pods" - the binary ran all the way to the point where it
needed something this host does not have.
The engine, evaluated, not served. This role installs the opa
binary and does not run opa run --server; that is a service with its own
listener, bundles and authorization, and a different artifact. The live
test evaluates a one-rule Rego v1 policy against a one-line YAML input
with opa eval and expects the denial message, the proof the engine
ran. OPA publishes a _static build beside the dynamic one and a
.sha256 for each; the role takes the dynamic build.

ansible-checkov
Checkov pinned in /opt/checkov, a virtual environment apart from the system Python. The live test runs pip check, scans a one-resource module with the built-in checks and --skip-download and expects a 'Failed checks:' summary with no network, and asserts the system Python cannot import it. Original role, live-tested on Rocky Linux 10.
ansible-conftest
conftest on EL 10 from the GitHub release, refused by Ansible's get_url unless its SHA-256 is the one in the project's checksums.txt, and re-checked with sha256sum -c by the live test, which then writes a one-rule Rego v1 policy and a one-line document, runs conftest test and expects the denial in the report. Original role, live-tested on Rocky Linux 10.
ansible-consul-cli
consul on EL 10 from releases.hashicorp.com: the client binary, not a server. HashiCorp's key lives in a GnuPG home of its own, pinned by fingerprint; the SHA256SUMS signature is verified before get_url checks the zip against that file, and the live test verifies it again, then runs consul members against nothing and expects the refused connection. Original role, live-tested on Rocky Linux 10.
ansible-gh-cli
gh on EL 10 from the release tarball, refused by Ansible's get_url unless its SHA-256 is the one in GitHub's checksums file, and re-checked with sha256sum -c by the live test; one more file to trust and no more repositories. Tokens are per user; gh auth status with none stops at 'not logged into any GitHub hosts', the live test's proof the client ran. Original role, live-tested on Rocky Linux 10.
ansible-infracost
infracost on EL 10 from the GitHub release, refused by Ansible's get_url unless its SHA-256 is the one in the per-asset .sha256 Infracost publishes, re-checked by the live test, which then runs a breakdown with no API key and expects it to stop there. The role exports INFRACOST_SKIP_UPDATE_CHECK=true for login shells and the live test reads it back. Original role, live-tested on Rocky Linux 10.
ansible-nomad-cli
nomad on EL 10 from releases.hashicorp.com: the client binary, not a server. HashiCorp's key lives in a GnuPG home of its own, pinned by fingerprint; the SHA256SUMS signature is verified before get_url checks the zip against that file, and the live test verifies it again, then runs nomad status against nothing and expects the refused connection. Original role, live-tested on Rocky Linux 10.
