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.

ansible-forgejo-runner
Forgejo Runner 13.2 from the vendor's release, sha256-checked, in a hardened unit, registered the way Forgejo now asks: a secret registered with forgejo-cli on the Forgejo host and a connection in config.yml. The live test pushes a workflow; its job runs on the runner and finds /home hidden, /tmp private and the system read-only. Original role, live-tested on Rocky Linux 10.
ansible-forgejo
Forgejo from the upstream release as a hardened service on loopback with sqlite and a configuration it never needs to write. The live test creates an administrator with Forgejo's own command, sees a wrong password refused and registration disabled, creates a private repository, hides it from an anonymous request and clones it over HTTP. Original role, live-tested on Rocky Linux 10.
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.
