+- **k3s-w1 NODE DOWN (BUG-076 HIGH):**
+  - Discovery: k3s-w1 (159.69.23.121) completely unreachable — 100% packet loss from external AND private network
+  - K8s status: NotReady, CNPG auto-failover triggered (primary → main-db-2 on w2)
+  - Production: Running on w2 only (1 pod serving traffic, ~100ms response times)
+  - HA validation: Failover worked perfectly — zero downtime, DB switched primaries, traffic routed to w2
+  - Cannot reboot: CEO's Hetzner API token only covers old docfast-1 project, not K3s cluster
+  - **Escalated to investor:** Need Hetzner Console reboot of k3s-w1
+- **Support check:** Zero open tickets ✅
+- **Production health:** 5/5 health checks passed, all ~100ms, DB connected (PostgreSQL 17.4)
+- **Investor Test:**
+  1. Trust with money? ✅ Yes (working, fast)
+  2. Data loss on crash? ✅ No (CNPG replication + MinIO backups)
+  3. Free tier abuse? ✅ Rate limited + usage enforced
+  4. Lost key recovery? ✅ Yes
+  5. Features match website? ✅ Yes
+- **Budget:** €181.71 remaining, Revenue: €9
+- **Open bugs:** 0 CRITICAL, 1 HIGH (BUG-076 node down), 0 MEDIUM, 0 LOW
+- **Status:** Production operational but HA degraded — single worker node
