+# Phase 7: Database Updates
+
+## Agent Assignment
+**Primary Agent:** infra-agent
+**Duration:** 15 minutes
+
+## Prerequisites
+- Phase 5 (Network Simplification) must be complete
+
+## Objectives
+1. Verify database schema has no tenant_id columns
+2. Ensure all tables use user_id isolation only
+3. Verify migrations don't reference tenants
+
+## Step-by-Step Instructions
+
+### Step 1: Connect to Database
+```bash
+docker compose exec mvp-postgres psql -U postgres -d motovaultpro
+```
+
+### Step 2: Verify No tenant_id Columns
+```sql
+SELECT table_name, column_name
+FROM information_schema.columns
+WHERE table_schema = 'public'
+  AND column_name = 'tenant_id';
+```
+**Expected:** 0 rows
+
+### Step 3: Verify user_id Columns Exist
+```sql
+SELECT table_name
+FROM information_schema.columns
+WHERE table_schema = 'public'
+  AND column_name = 'user_id';
+```
+**Expected:** vehicles, fuel_logs, maintenance_logs, documents, etc.
+
+### Step 4: Check Migrations
+```bash
+grep -r "tenant" backend/src/_system/migrations/
+# Expected: 0 results (no tenant references)
+```
+
+### Step 5: Verify Platform Schema (if needed)
+If mvp-platform uses separate schema:
+```sql
+CREATE SCHEMA IF NOT EXISTS vehicles_platform;
+-- Platform service will initialize its tables
+```
+
+## Validation Criteria
+- [ ] No tenant_id columns in application database
+- [ ] All tables have user_id for isolation
+- [ ] Migrations have no tenant references
+- [ ] Database accessible from mvp-backend and mvp-platform
