"""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.
