Found by the interop run against pinned peers. The End of Range's Group ID was read and
written as a delta from the prior entry (-22 11.4.1.2, -18 11.4.4.2: the Group ID and
Object ID fields; -23 A.1 is where it becomes delta-coded). Both corpora and both
independent decoders follow. The -16 bridge sent -22's number for codes -16 does not
register (13.4.2).
