Trace a build to reviewed inputs
Record the source revision, build job, and approved dependency changes with the artifact. Restrict publishing credentials to the release job. Review the contents of the finished player or website bundle so local configuration and credentials stay out of public output.
Practice a recovery path
Rehearse reverting to a known release in a test environment. Check what happens when a data migration or client version survives the rollback. Document which artifacts can be reissued and which credentials can be rotated to contain a problem.
