Parameter Passing And Variable Interpolation Across Workflow Steps

Kubernetes-native workflow engine.

Unique: Implements parameter passing as a declarative workflow concern with template-level interpolation, avoiding the need for container-level environment variable parsing. Parameters are resolved by the workflow-controller before pod creation, enabling static analysis and validation.

vs others: More explicit than Airflow XCom (parameters declared upfront) and simpler than Kubeflow Pipelines (no type system overhead), but less type-safe than strongly-typed workflow systems.
