Function buildExperimentArtifactDownloadSteps

pkg/workflow/compiler_experiments.go:566–576

buildExperimentArtifactDownloadSteps creates a download step for the experiment artifact. The artifact is downloaded to experimentsCacheDir so the detection agent can read the current variant assignments from state.json. The step is a no-op when no experiments are declared. pinAction resolves the do
