"""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 via DOOR_GENERIC
pattern capability that auto-derives distinct keys from the href segments.
