+"""An OEM wrapper archive must not read as an empty bug report.

+MIUI / HyperOS hands out a zip of app logs with the real
+`bugreport-<device>-<timestamp>.zip` nested inside. The outer archive has
+none of the entry points the modules read, so every module
+reported it found nothing and the command still exited 0 — an empty analysis
+that looks like a finished one.
