+# The goth network depends on the host daemon, docker credentials, cached
+# images and the container-side yagna configuration, so when a run fails it is
+# hard to tell from the pytest output which of those layers is at fault.  These
+# helpers capture a snapshot of the relevant state so it can be inspected
+# after the fact.  They are strictly read-only and never fail the caller.
