 ## Notable findings / TODOs
 - ⚠️ **compute6 NIC runs at 100 Mb** (ethtool-confirmed; the K10 has 2.5 GbE) — bad cable/switch port. `speedtest-tracker` runs on this node, so its WAN results are capped/misleading. Fix the cable/port.
 - **beast concentration / SPOF** — PVE master + NUT master + GPUs + TrueNAS + Media-Server + Nextcloud + DNS all on one machine.
 - **Kernel skew** — docker-node01/02 + ansible-control on 6.8.0-111 (pending update); media-server 6.8.0-134; PVE nodes 6.17.13-pve.
-- **Deferred (need root sudo):** serials/DIMM/SMART on beast, compute2, compute3, compute4, pbs; TrueNAS `tank` disk-passthrough map; Synology model.
+- **Disk SMART/serials: DONE for all 6 PVE nodes** (via Proxmox API, no sudo). Still deferred: **DIMM layout + system serial on beast/compute2/3/4** (need `sudo`; the password tried was rejected), **pbs disk SMART/serials** (PBS API token id unknown, sudo pw rejected), TrueNAS `tank` disk-passthrough map, Synology model.
