"""Integrity tests for the binary release-asset naming convention.

`binary_name`, `versionless_alias` and `binary_filename_re` are the one
definition of the `{package}-{version}-{target}.{ext}` convention that the
release engine, the install-guide freeze, and the binaries catalog all build
on. These tests pin the convention against every `NUITKA_BUILD_TARGETS`
entry.
