I don't have a precise definition.
This is what I would advance:

  + A walled-garden network is provided by a service-specific internet
    service provider (SS/ISP) to a residential or small office.  
  + The service-specific connection is in the form of a dedicated WAN link into
    the dwelling. (The link may be physical or might be carried by a virtual
    layer-2).  Some dwellings may have only the service specific connection.
  + The service-specific connection provides access to a service
    (IPTV is a known example), and is not general Internet service.
  + The IPv6 service is reachable only using IPv6 from a block that the
    service-specific ISP will allocate to the residence using regular
    mechanism.  
  + The IPv6 service is numbered using globally unique IPv6 addresses,
    which are usually not accessible outside of the "garden", i.e. they
    are not routed in the global Default-Free Zone.
  + In IPv6, no special DNS tricks are required to make the clients
    systems pick the right target address.  Multiple AAAA records, 
    (possibly with walled-garden ACLs on authoritative servers) and
    happy eyeballs is enough.

A walled-garden is no different than a multiple ISPs in a residence,
except that general internet traffic does not transit that connection.
