Cost Optimisation Opportunities

  1. bms-1 (Pinbox24) — server is disk-full and runs EOL Ubuntu; migrating to bms-3 or a newer OVH could consolidate costs
  2. Claude Max seats — 20 seats is the current fleet; review utilisation via AI-Dev-* agent logs
  3. Wasabi — single p24-infra bucket, separate billing is not broken down by folder; cost-exporter gives aggregate
