+This graph differs from the previous snapshot in exactly two ways. #12 and #18
+both advanced, which adds #12+#18, #17+#18, and #12+#19. And #19 no longer
+duplicates the repo-wide hygiene legacy-exception mechanism that #18 also
+carries, which makes #18+#19 clean. Recompute before every integration step;
