"""A targeted pack is checked under the target reading it was built with.

`--all --target x86_64` packs a platform that has no target file unnarrowed
under the target's name (Recalbox, Lakka, BizHawk, MiSTer, ROCKNIX). The
conformance check read the same target without the --all tolerance, raised
FileNotFoundError on the first of those packs and stopped the run in a
traceback after every pack had been written.
