"""A platform declaration that a content-found core entry accepts by hash.

atari800 identifies its ROMs by CRC32 in the folder it scans. RetroDECK
lists Atari BASIC Rev A as ROM_BASIC_A, a name atari800 never opens, and
the profile answered it with a false alias. Settled by content instead, the
declared file meets the entry and the label is not shipped a second time.
