Suspend/resume kills the GPU-side duo member (CUDA context lost; often wedged nvidia_uvm on this machine). Daemon now ticks every 60s: if exactly one duo member is running, the missing one is reloaded via its /upstream health endpoint and its snapshot restored. Saves stay at 5-min cadence. Boot restore skips members that are already running. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
