## Changelog
### 2026-04-29 — relocated to better-ventilated spot
User physically moved the host to a new location with improved airflow. Post-move idle baseline (45 min uptime, light load): k10temp Tctl **47.2 °C**, amdgpu edge 42 °C, nvme0 composite 34.9 °C / sensor1 32.9 °C, nvme1 composite 38.9 °C / sensor1 52.9 °C, DRAM 34–35.5 °C, ACPI zone 47–49 °C. Compares well against the 2026-04-23 thermal-pad steady-state (nvme0 sensor1 60–61 °C). Watch the lifetime NVMe warning-time counter over the coming days for confirmation. See [investigation](../investigations/2026-04-21-hubris-crash-loop.md#2026-04-29-physical-relocation).
### 2026-04-28 — Phase 1 WiFi failover
Host now dual-homed: LAN `192.168.8.77` (primary) + WiFi `192.168.8.141` (failover, metric 200) on the GL-AXT1800-714-5G AP. Installed `wpasupplicant`+`iw`; added `wlp3s0` stanza to `/etc/network/interfaces` with `wpa-conf`; ARP isolation sysctls in `post-up`. Built `wan-failover.service` to remove the vmbr0 default route on `eno1` carrier loss, since the bridge's carrier doesn't follow `eno1` (the LXC veths keep it `1`). LXC/VM guests are still LAN-only — Phase 2 will migrate them.
