"""A profile names each repository under the name its forge answers today.

GitHub follows a renamed or transferred repository's old name in silence:
flycast2021 declared libretro/flycast, which answers as libretro/parallel-dc,
and reicast declared reicast/reicast-emulator, which answers as
skmp/reicast-emulator. profile_sync counts such a move as review work. This
test reads the forge answers profile_sync has cached and fails on any
profile still declaring an old name. Without a cache it has nothing to read
and skips.
