"""A filename-agnostic scan seeds only from the build the platform runs.

armsx2 declares bios_mode: agnostic, and its proverb.zip is a standalone
file the Android app fetches into its arcade/ folder. The scan never read
`mode:` and put it at system/proverb.zip in every pack running armsx2 as a
libretro core, while verify set the entry aside. Reads the repository.
