+		\textbf{The reexecution system encompasses both Article Reexecution, and the Meta-Article as independent Make targets.}
+		Depicted is the workflow of the re-execution system, with two reexecution entry points, the “Original Article”, the “Meta-Article” (i.e. \textit{this} article, which also performs the reproduction assessment).
 		Notably, for the generation of the meta-article, the Original Article can be executed, or not — the meta-article will dynamically include all reexecution results which are published, as well as all which are locally produced.
 		The article reexecution PDF results are highlighted in light green, and the PDF of the resulting meta-article (i.e. this article) is highlighted in light blue.
+		Optional nodes (such as fetching a container image for meta-article reexecution) are faded gray.
