Proxmox Host
The Annex runs the same Proxmox VE baseline as the Manor, but as a single standalone host rather than a cluster member. It carries the heavy, I/O-bound work — build pipelines, source forges, public-facing web traffic — where raw throughput matters more than surviving a node failure.
Same framing technique, different posture: where the Manor trades capacity for resilience, the Annex spends it on power. If this box goes down, its rooms go down with it — an accepted trade for the workloads it holds. What runs where is detailed in the Hardware Manifest.
