+ * so from the day the control arrived until 2026-08-03 every test in this file
+ * skipped and the whole delegated-write journey ran nowhere. The file said out
+ * loud what to change and nobody changed it, which is the standing lesson
+ * about a check that cannot fail: the skip is quiet, and a quiet skip and a
+ * passing suite look identical in a CI summary.
  *
- * The skip is deliberately loud rather than silent: it names the missing
- * control, so a run where the control exists and the journey still does not
- * execute reads as a bug in this file rather than as an absence upstream.
