yamlfmt, Lint, Format, Lint Again
yamlfmt on EL 10 from the GitHub release; get_url refuses it unless its SHA-256 is in the vendor's checksums file, and the live test re-checks it, then writes a misindented file, expects -lint to exit 1, formats it in place, reads the result back byte for byte and expects the second lint to exit 0. Pinned. Original role, live-tested on Rocky Linux 10.

Documentation
yamlfmt
Google yamlfmt 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 yamlfmt, and a
third-party repository is one more key to trust. This role takes the
release from github.com/google/yamlfmt, 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. yamlfmt_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 yamlfmt -lint /tmp/yamlfmt-p/in.yaml and expects
"formatting differences" - the binary ran all the way to the point where it
needed something this host does not have.
Lint, format, lint. The live test writes a misindented YAML file,
expects yamlfmt -lint to exit 1 and name the formatting differences,
formats the file in place, reads it back byte for byte (a: 1 and a
two-space list) and expects the second lint to exit 0. Both halves of the
tool are proven: the check a CI job runs, and the rewrite a developer
runs.

Related modules
ansible-atmos
atmos on EL 10 from the GitHub release, get_url refuses it unless its SHA-256 is the one in the vendor's SHA256SUMS, and the live test re-checks it, then writes an atmos.yaml, a stack and a component, validates the stacks and describes the component with no Terraform installed. Pinned. Original role, live-tested on Rocky Linux 10.
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-glab
glab on EL 10 from the GitLab-hosted release, get_url refuses it unless its SHA-256 is the one in the vendor's checksums file, and the live test re-checks it, then runs auth status to the 401 gitlab.com returns and round-trips a config value offline. Pinned. Original role, live-tested on Rocky Linux 10.
