+# Phase 5: Network Simplification
+
+## Agent Assignment
+**Primary Agent:** infra-agent
+**Duration:** 15 minutes
+
+## Prerequisites
+- Phase 1 (Docker Compose) must be complete
+
+## Objectives
+1. Reduce networks from 5 to 3
+2. Remove platform and egress networks
+3. Update service network assignments
+4. Maintain proper isolation
+
+## Step-by-Step Instructions
+
+### Step 1: Update docker-compose.yml Networks Section
+
+**Remove these networks:**
+```yaml
+# DELETE:
+platform:
+  driver: bridge
+egress:
+  driver: bridge
+```
+
+**Keep these networks:**
+```yaml
+networks:
+  frontend:
+    driver: bridge
+  backend:
+    driver: bridge
+  database:
+    driver: bridge
+```
+
+### Step 2: Update Service Network Assignments
+
+```yaml
+mvp-traefik:
+  networks:
+    - frontend
+
+mvp-frontend:
+  networks:
+    - frontend
+    - backend  # Needs to reach backend API
+
+mvp-backend:
+  networks:
+    - backend
+    - database  # Needs to reach postgres and redis
+
+mvp-postgres:
+  networks:
+    - database
+
+mvp-redis:
+  networks:
+    - database
+
+mvp-platform:
+  networks:
+    - backend    # Reached by mvp-backend
+    - database   # Reaches postgres and redis
+```
+
+### Step 3: Restart Services
+```bash
+docker compose down
+docker compose up -d
+```
+
+### Step 4: Verify Network Configuration
+```bash
+# List networks
+docker network ls | grep motovaultpro
+# Expected: 3 networks (frontend, backend, database)
+
+# Test connectivity
+docker compose exec mvp-backend ping -c 1 mvp-postgres
+docker compose exec mvp-backend ping -c 1 mvp-platform
+# Expected: Successful
+```
+
+## Validation Criteria
+- [ ] Only 3 networks exist (frontend, backend, database)
+- [ ] All services can communicate as needed
+- [ ] No platform or egress networks
+- [ ] Traefik routing still works
+
+## Update EXECUTION-STATE.json
+```json
+{
+  "phases": {"5": {"status": "completed", "validation_passed": true}}
+}
+```
