+# Tenancy Change Log - December 9, 2024
+
+## Summary
+This document tracks all changes made to the multi-tenancy system during the current staging session and the last 2 commits (4d13a570 and 72d0b6b0).
+
+---
+
+## 🔧 Recent Session Changes (Uncommitted)
+
+### 1. Authentication & Signup Flow
+**Fixed: JWT Token Generation in Registration**
+- **Issue**: Users were immediately logged out after signup because tokens weren't being returned
+- **Root Cause**: Two separate `register` endpoints existed - one in `AuthViewSet` (unused) and one in `RegisterView` (actual endpoint)
+- **Fix**: Updated `RegisterView` in `backend/igny8_core/auth/urls.py` to generate and return JWT tokens
+  ```python
+  # Added token generation to RegisterView
+  access_token = generate_access_token(user, account)
+  refresh_token = generate_refresh_token(user, account)
+  # Return tokens in response data
+  ```
+- **Files Changed**: `backend/igny8_core/auth/urls.py`
+- **Impact**: Users now stay logged in after successful registration
+
+**Enhanced: Frontend Token Extraction**
+- **Issue**: Frontend couldn't parse tokens from backend response structure
+- **Fix**: Added multiple fallback paths in `authStore.ts` to handle nested response structure
+  ```typescript
+  // Handle both data.tokens.access and data.data.tokens.access
+  const newToken = tokens.access || responseData.access || data.data?.tokens?.access
+  ```
+- **Files Changed**: `frontend/src/store/authStore.ts`
+
+### 2. Payment Confirmation Modal
+**Fixed: Invoice Amount Display**
+- **Issue**: Amount showing as "PKR 0.00" in payment confirmation modal
+- **Root Cause**: Frontend expected `total` field but backend returned `total_amount`
+- **Fix**: Updated invoice API to return both fields for compatibility
+  ```python
+  'total': str(invoice.total),  # Alias for compatibility
+  'total_amount': str(invoice.total),
+  ```
+- **Files Changed**: 
+  - `backend/igny8_core/business/billing/views.py`
+  - `frontend/src/components/billing/PaymentConfirmationModal.tsx`
+  - `frontend/src/components/billing/PendingPaymentBanner.tsx`
+
+### 3. Payment Approval Workflow
+**Fixed: Manual Status Change Not Triggering Account Activation**
+- **Issue**: When admin changed payment status to "succeeded" in Django admin, it didn't activate account or add credits
+- **Root Cause**: `save_model()` only set `approved_by` but didn't run the full approval workflow
+- **Fix**: Enhanced `save_model()` in `PaymentAdmin` to trigger complete workflow:
+  - Update invoice status to 'paid'
+  - Activate subscription status to 'active'
+  - Activate account status to 'active'
+  - Add credits based on plan
+  - Prevent duplicate credit transactions
+- **Files Changed**: `backend/igny8_core/modules/billing/admin.py`
+- **Impact**: Admins can now manually approve payments in Django admin with full automation
+
+### 4. Site Creation Permissions
+**Fixed: Site Creation Failing Due to Permission Issues**
+- **Issue**: Users couldn't create sites and were getting logged out
+- **Root Cause**: 
+  1. `SiteViewSet.get_permissions()` wasn't properly returning instances
+  2. Domain field validation rejected empty strings
+- **Fixes Applied**:
+  - Updated `get_permissions()` to return instantiated permission classes
+    ```python
+    return [IsAuthenticatedAndActive(), HasTenantAccess(), IsEditorOrAbove()]
+    ```
+  - Modified domain validation to accept empty/None values
+    ```python
+    if not value or value.strip() == '':
+        return None
+    ```
+- **Files Changed**: 
+  - `backend/igny8_core/auth/views.py`
+  - `backend/igny8_core/auth/serializers.py`
+
