+# Scoped to THIS installation's path, not to the script names. pgrep is system-wide, and a box
+# running both a production checkout and a development clone will always have one of them busy —
+# matching on "Orchestrators/" alone made a dev migration abort because prod was mid-cycle, which
+# is a process that cannot touch this tree's data at all. The full path is what distinguishes
+# them, so that is what is matched.
