 - ✅ **Type safety** - Full TypeScript support from better-auth
 - ✅ **Programmatic API** - Access auth methods via `authManager.api`
 
+#### ObjectQL Database Architecture
+
+The plugin uses **ObjectQL** for data persistence instead of third-party ORMs:
+
+```typescript
+// Object definitions replace ORM schemas
+export const AuthUser = ObjectSchema.create({
+  name: 'auth_user',
+  fields: {
+    id: Field.text({ label: 'User ID', required: true }),
+    email: Field.email({ label: 'Email', required: true }),
+    name: Field.text({ label: 'Name', required: true }),
+    // ... other fields
+  },
+  indexes: [
+    { fields: ['email'], unique: true }
+  ]
+});
+```
+
+**Benefits:**
+- ✅ **No ORM Dependencies** - No drizzle-orm, Prisma, or other ORMs required
+- ✅ **Unified Data Layer** - Uses same data engine as rest of ObjectStack
+- ✅ **Driver Agnostic** - Works with memory, SQL, NoSQL via ObjectQL drivers
+- ✅ **Type-Safe** - Zod-based schemas provide runtime + compile-time safety
+- ✅ **"Data as Code"** - Object definitions are versioned, declarative code
+- ✅ **Metadata Driven** - Supports migrations, validation, indexing via metadata
+
+**Database Objects:**
+- `auth_user` - User accounts (email, name, emailVerified, etc.)
+- `auth_session` - Active sessions (token, expiresAt, ipAddress, etc.)
+- `auth_account` - OAuth provider accounts (providerId, tokens, etc.)
+- `auth_verification` - Verification tokens (email, phone verification)
+
+**Adapter:**
+The `createObjectQLAdapter()` function bridges better-auth's database interface to ObjectQL's IDataEngine:
+
+```typescript
+// Better-auth → ObjectQL Adapter
+const adapter = createObjectQLAdapter(dataEngine);
+
+// Better-auth uses this adapter for all database operations
+const auth = betterAuth({
+  database: adapter,
+  // ... other config
+});
+```

Subject: [PATCH 6/6] Use better-auth native naming conventions for seamless
 migration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Changed table names: auth_user → user, auth_session → session, etc.
- Changed field names: email_verified → emailVerified, created_at → createdAt, etc.
- Removed name conversion logic from adapter (no longer needed)
- Updated documentation to reflect better-auth native schema usage
- All tests passing (11/11)

This ensures existing better-auth databases can migrate without schema changes.
