"""protocol/ and ocf/ must be vendorable on their own — no dependency
on mqtt_demo/. This copies just those two directories into an empty
temp dir and imports every module in them there, so a stray
`from mqtt_demo... import ...` fails loudly instead of silently
passing because mqtt_demo/ happens to also be on sys.path in-repo."""
