memory: snapshot — GX10 liveness confirmed; racking is not a prerequisite

Browse Source 
Probed the box read-only. Alive and idle at 11h48m uptime, 118 of 121 GB
memory free, 822 GB disk free, and completely unchanged since onboarding:
no torch, no nvcc, no uv, and infra-ops is not in the docker group.

The useful finding is a negative one. I assumed the temporary Wi-Fi would
gate getting a 49 GB base model onto the box and it does not. The link is
Wi-Fi 7 on 6 GHz at 2401.9 Mbit/s with a -48 dBm signal, and a measured
300 MB transfer ran at 67 MB/s over SSH, which puts the full base at
about twelve minutes. SSH's cipher is the limiter there, not the radio.
So the throughput probe can run from the desk today and racking is worth
doing for permanence rather than as a blocker.

Also recorded that nvidia-smi reporting FB Memory and BAR1 as N/A is
correct for GB10 rather than a driver fault, since the Grace Blackwell
superchip shares unified LPDDR5X between CPU and GPU and has no discrete
VRAM figure to report.
