bench-conversation.py answers 'what does this endpoint feel like': ten real jobs streamed once, TTFT split from decode tok/s, salted so no arm inherits a warm cache, optional concurrent burst for capacity. Needed to compare the two tensor-parallel runtimes the 2026-09-20 board swap unblocked. dankserver-route-primary.sh pins eno1 (the fleet address, .235) as the preferred default route after the board swap brought up eno2 with DHCP and a lower metric; eno2 stays up as failover. nmcli device reapply, not connection up, so the link this session rides is not torn down.

# The 2026-09-20 board swap (TUF GAMING B650-E -> ProArt B850-Creator WiFi NEO)
|
|
# brought up a second port, eno2, which took DHCP and — with NetworkManager's
|
|
# default per-connection metric of 100 — came up with metric 101 while eno1's
|
|
# static gateway got 102. Outbound traffic therefore started leaving by eno2
|
|
# even though every fleet peer, Caddy upstream and monitoring target addresses
|
|
# this host as .235. Keep eno2 (it is a real second link) but make it secondary:
|
|
# route metrics decide the default route, so eno1 wins while eno2 stays a
|
|
# failover.
