 Complete audit of all Firefrost Gaming infrastructure to document every service, port allocation, and interconnection. Prevents port conflicts and creates comprehensive network diagram.
 
 **Key Deliverables:**
-- Server inventory (6 servers: Command Center, Ghost VPS, Billing VPS, Panel VPS, TX1, NC1)
-- Port allocation registry (what's used, what's reserved, what's free)
-- Service audit per server (systemd, Docker, native apps)
-- Connectivity map (internal server-to-server, external public-facing)
-- Dependency graph (database connections, API calls, webhooks, authentication flows)
-- Visual network diagram (Mermaid or similar)
+- ✅ Server inventory (6 servers: Command Center, Ghost VPS, Billing VPS, Panel VPS, TX1, NC1)
+- ✅ Port allocation registry (90+ services documented)
+- ✅ Service audit per server (systemd, Docker, native apps)
+- ✅ Connectivity map (internal server-to-server, external public-facing)
+- ✅ Dependency graph (database connections, API calls, webhooks, authentication flows)
+- ✅ Visual network diagram (Mermaid)
+- ✅ 14 game servers mapped to UUIDs and connection strings
+- ✅ 68 Docker containers inventoried
+- ✅ Single points of failure identified
+- ✅ Disk usage warnings documented (Billing 70%, NC1 66%)
 
-**Methodology:**
-1. SSH to each server via Cockpit
-2. Run `netstat -tlnp | grep LISTEN` to identify all listening ports
-3. Run `systemctl list-units --type=service --state=running` for systemd services
-4. Run `docker ps` if Docker is present
-5. Document configuration files for each service
-6. Map data flows between services
+**Audit Results:**
+- No current port conflicts detected
+- All critical services operational
+- 2 warnings: High disk usage on Billing VPS and NC1
+- Known issue: Ghost VPS port 25 blocked at provider level
+- Plane monitor container in restart loop (investigate)
 
-**Why This Matters:**
-- Prevents port conflicts (e.g., The Arbiter tried 3000 → 3001 → 3500)
-- Documents authentication dependencies (OAuth, SMTP, API tokens)
-- Shows single points of failure
-- Enables informed architecture decisions
-- Essential for disaster recovery planning
+**Output Files:**
+- `docs/infrastructure/network-audit-2026.md` (600+ lines, comprehensive)
+- `docs/infrastructure/network-diagram-2026.mmd` (Mermaid visual diagram)
 
-**Output Location:** `docs/infrastructure/network-audit-2026.md`
-
-**Dependencies:**
-- Cockpit access to all 6 servers
-- Root SSH access
-- ~2 hours uninterrupted audit time
-
-**Next Session Priority:** Execute this FIRST before any other infrastructure work.
+**Git Commit:** `8ddaf76` - "feat: complete infrastructure audit and network topology map"
