.. py:function:: test_an_all_ones_version_word_decodes_as_not_advertised() -> None

   Two readers used to disagree on this exact word: one mapped it to
   (0, 1) — a plausible-looking old shell — while the other ran it
   through from_u32 and got (65535, 65535), which compares GREATER than
   the capability-word version and so read words the shell never
   decoded. A sentinel below every real version makes them agree.
