+
+**Notes:**
+- Installed 2026-07-28 (bare-metal). UEFI boot from the internal mSATA required a manual `efibootmgr` NVRAM entry (`\EFI\BOOT\BOOTX64.EFI`) — ASRock Q1900 firmware will not auto-create a UEFI boot entry for a fixed SATA disk (boots from USB only). Booted a SystemRescue USB in UEFI mode and ran `efibootmgr -c -d /dev/sda -p 1 -L "HAOS" -l '\EFI\BOOT\BOOTX64.EFI'`.
+- Network: was silent on the CSS326 Kids port (Port 18, VLAN 25 — that VLAN is not trunked to the router). Moved to Port 3 (VLAN 10) → got DHCP immediately.
+- Reverse proxy: Traefik `ha.xtrm-lab.org` → `192.168.10.102:8123`; HA `http.trusted_proxies` = `192.168.10.20`, `172.18.0.0/16` (required — new HA returns HTTP 400 to proxied requests otherwise).
+- Old HA VM (`192.168.10.20:8123`) kept as fallback, now reachable by IP only.
