Re-read on every heartbeat. A port that goes down takes its fabric off this node within seconds; one that comes back returns it. Errors are cumulative since the adapter came up: a number that grows is the one to look at.

NV is a pair of cards joined by NVLink; a tensor-parallel group kept to NV pairs runs its all-reduces at NVLink speed, and placement picks it that way. The nearest adapter is where a card's share of traffic between nodes should go: PIX and PXB are under the same PCIe switch, SYS is across the processors.
