     |    any code exists that treats it as
     |    a client version) but are ignored on
     |    deserialization.
     |
     |  - The high bits (masked by
     |    ~DISK_VERSION_IGNORE_MASK) store actual
     |    serialization information.  Only 0 or
     |    DISK_VERSION_ADDRV2 (equal to the
     |    historical ADDRV2_FORMAT) are valid now,
     |    and any other value triggers
     |    a deserialization failure. Other values
     |    can be added later if needed.
     |
     |  For disk deserialization, ADDRV2_FORMAT in
     |  the stream version signals that ADDRV2
     |  deserialization is permitted, but the
     |  actual format is determined by the high
     |  bits in the stored version field. For
     |  network serialization, the stream version
