On 2026-09-29 the NVMe SSDs of `youko` and `shushou` were physically swapped, and the 2×4TB USB HDDs
moved with the `youko` role to the other chassis. The reason was Jellyfin: HDR transcoding on the
5625U's Barceló iGPU could not keep up (~0.4–0.8×), while the 5900HX's Cezanne iGPU can (~1.68× for
1080p HDR). So the homelab-core role (all services + one k3s VM + the HDDs + the UPS) now runs on
the Beelink GTR5 and the k3s VM-host role on the UM560; the other services moving along is a side
effect of swapping the role's disk, not a separate migration. Hostnames, IPs, and state followed the
disks.
