AWM-WW-AID-26-ONEBODY (washer+dryer combo) reports numofsubdevice='2' on
/multidevice/vs/0 but carries no /subdevices/vs/0 (no subdeviceIdList --
Pattern B's signal) and 4.04s /device/1 and /device/2 (Pattern A's). The
washer subdevice's UUID appears only as the path prefix of the
x.com.samsung.da.multidevice link in /oic/res; GET /<uuid>/device/0
answers the washer's own full Collection batch (model ..._WF80H vs the
master's ..._DV80H27H).
Treat every UUID path prefix seen in /oic/res as a prefixed-subdevice
candidate (minus ones subdeviceIdList already named), probed with the
same tolerated-404 seed RETRIEVE as Pattern B -- the shared body is
factored into _probe_prefixed. discover_partitioned's entity-level
liveness gate still decides materialization, so a UUID link with no live
sibling behind it contributes nothing.
Fixture is a live capture from the reporting board (serials/MACs/di
scrubbed); tests cover discovery, probe hygiene, washer-side entity
binding, and that the master's own entity set is unchanged.
