"""Verify that multi-instance fridge resources produce distinct entity keys.

The two physical door resources (/door/cooler/0, /door/freezer/0) and the two
ice-maker resources (/icemaker/one/vs/0, /icemaker/two/vs/0) use named path
segments rather than numeric indices, so they are modelled as separate
Capability objects with distinct entity keys.
