Git First Parent History View Visual

Using [repository], [merge commit], [history question], create the verified merge graph with first-parent edges emphasized and side branches still visible. Compare ordinary and first-parent history for the supplied merge using read-only commands. Explain which parent path each view follows; do not equate a hidden side-branch commit with absent code or rewrite history. Use a deliberate focal point and leave unsupported exact labels blank.

Use the attached references only for the specified visual attributes. If a required reference is missing, request it before generation. Produce one finished image with a deliberate focal point, consistent geometry and clean margins. Keep any exact wording on a separate editable label layer or leave its area blank. Do not invent evidence or present an illustration as documentary proof.
