+# But "no assertions" has two very different causes, and only one of them is the
+# entry's problem. If coverage exists and the tool it needs was simply absent,
+# that is an environment gap: the validate job runs on ubuntu-latest, which never
+# builds the load-generator images (benchmark.sh does that, on the self-hosted
+# runner), so h3 checks skip there and would fail every h3-only entry for a
+# reason that has nothing to do with the entry. Warn loudly and pass.
+# Fail only when validate.sh genuinely has no checks for anything subscribed.
