- pct-run.sh: add CT 109 note (KVM VM), document decommissioned/migrated CTs
- disk-gc-threat-response: add docker-vm (SSH .7), add amdpve Docker scope,
  remove jitsi (decommissioned), update access matrix with KVM VM section
- infrastructure-control: docker-vm container count 11→16, add Trove agents stack
- infrastructure-monitoring: deployment status updated (core live, GPU exporters not deployed)

-  already deployed by proxmox-monitor contract. GPU exporters (.8/.110/.15)
-  NOT yet live — gpu-exporter crash-loops on .15, sidecars never deployed.

+  DEPLOYMENT STATUS (2026-07-09):
+  ✅ Core stack deployed: Prometheus + Grafana + pve/node/docker exporters
+     (via proxmox-monitor contract). Grafana at :3001, 5 scrape targets active.
+  ❌ GPU exporters NOT deployed: gpu-exporter crash-loops on .15,
+     NVIDIA sidecar exporters (.8/.110:9400) never installed.
+     Router falls back to direct GPU /health probes.
+  ⚠️ This contract is target-state aspirational — not as-built.
+     As-built GPU monitoring is via gpu-monitor contract (port 9100 poll).
