# Tenancy System Implementation Summary
## Complete Context for Future Implementation

**Date:** 2025-12-08  
**Status:** Analysis Complete, Ready for Implementation  
**Database State:** Analyzed via Docker  

---

## What I've Done (Context Gathering)

### 1. Analyzed Documentation

- ✅ Read [`tenancy-implementation-plan.md`](tenancy-implementation-plan.md) - Original plan

### 2. Analyzed Codebase
- ✅ Read all auth models, serializers, views
- ✅ Read middleware, authentication, permissions
- ✅ Read credit service and AI engine

## Code Changes Made (Review Before Using)

### ⚠️ Backend Changes (Review First)
1. **[`backend/igny8_core/auth/serializers.py:276`](backend/igny8_core/auth/serializers.py:276)**
   - Modified RegisterSerializer.create()
   - Auto-assigns 'free-trial' plan
   - Seeds credits on registration
   - Sets status='trial'
   - Creates CreditTransaction

2. **[`backend/igny8_core/auth/management/commands/create_free_trial_plan.py`](backend/igny8_core/auth/management/commands/create_free_trial_plan.py)**
   - New command to create free-trial plan
   - Sets 2000 credits, 1 site, 1 user, 3 sectors

### ⚠️ Frontend Changes (Review First)
1. **[`frontend/src/components/auth/SignUpForm.tsx`](frontend/src/components/auth/SignUpForm.tsx)**
   - Removed plan loading and selection
   - Simplified to name/email/password
   - Changed heading to "Start Your Free Trial"
   - Redirect to /sites instead of /account/plans

## Current Database State Summary

### Plans (5 total)
| Slug | Name | Price | Credits | Sites | Users | Active |
|------|------|-------|---------|-------|-------|--------|
| free | Free Plan | $0 | 100 | 1 | 1 | ✅ |
| starter | Starter | $89 | 1,000 | 1 | 2 | ✅ |
| growth | Growth | $139 | 2,000 | 3 | 3 | ✅ |
| scale | Scale | $229 | 4,000 | 5 | 5 | ✅ |
| enterprise | Enterprise | $0 | 10,000 | 20 | 10,000 | ✅ |

### Accounts (8 total)
- **Active:** 3 accounts
- **Trial:** 5 accounts
- **Credits range:** 0 to 8,000
- **Most used plan:** enterprise (4 accounts)

### Users (8 total)
- **Roles:** 1 developer, 7 owners
- **All have accounts** (account field populated)
- **All are owners** of their accounts

### Sites (4 total)
- All properly linked to accounts
- All have industries assigned
- Sectors: 1-5 per site (within limits)

### Subscriptions
- **None exist** (payment system not implemented)
- Model exists but unused
- Future implementation needed

---

## Critical Gaps (Still Need Implementation)

### 1. Payment Method Fields (HIGH)
**Status:** ❌ Don't exist in database  
**Files affected:** 
- Account model
- Subscription model
- Serializers
**Action:** Create migration 0007

### 2. Credit Seeding on Registration (HIGH)
**Status:** ⚠️ Code updated but not deployed  
**Current:** Accounts created with 0 credits  
**Fixed:** RegisterSerializer now seeds credits  
**Action:** Deploy updated serializer

### 3. API Key Bypass (HIGH)
**Status:** ❌ Not fixed  
**Issue:** WordPress bridge can access suspended accounts  
**Action:** Add validation in APIKeyAuthentication

### 4. Throttling (MEDIUM)
**Status:** ❌ Not fixed  
**Issue:** All authenticated users bypass throttling  
**Action:** Remove blanket bypass, add per-account keying

### 5. Bank Transfer Support (MEDIUM)
**Status:** ❌ Not implemented  
**Issue:** No way to confirm manual payments  
**Action:** Create billing endpoint

## Relationships Confirmed

### Plan → Account (1:many)
```
Plan.accounts → Account objects
Account.plan → Plan object
```
✅ Working correctly

### Account → User (1:many)
```
Account.users → User objects
User.account → Account object (nullable)
Account.owner → User object (one specific user)
```
✅ Working correctly

### Account → Site (1:many)
```
Account.site_set → Site objects (via AccountBaseModel)
Site.account → Account object (db_column='tenant_id')
```
✅ Working correctly, unique_together=(account, slug)

### Site → Sector (1:many)
```
Site.sectors → Sector objects
Sector.site → Site object
Sector.account → Account object (auto-set from site)
```
✅ Working correctly, validates sector limits

### User → Site (many:many via SiteUserAccess)
```
User.site_access → SiteUserAccess objects
Site.user_access → SiteUserAccess objects
```
✅ Working for granular access control

---

## Permission Flow Confirmed

### Authentication
```
Request → Middleware
  ↓
JWT/Session/APIKey → Extract account
  ↓
Set request.account
  ↓
Validate account.status (trial/active allowed)
  ↓
Validate account.plan.is_active
  ↓
Block if suspended/cancelled
```

### Authorization
```
ViewSet Permission Classes
  ↓
IsAuthenticatedAndActive → Check user.is_authenticated
  ↓
HasTenantAccess → Check user.account == request.account
  ↓
Role-based → Check user.role in [required roles]
  ↓
Object-level → Check object.account == user.account
```

### Tenancy Filtering
```
AccountModelViewSet.get_queryset()
  ↓
Filter by request.account
  ↓
Returns only objects where object.account == request.account
```

✅ **All working correctly**

## Rollback Strategy If Needed

### If Code Changes Cause Issues
```bash
# Revert serializer
git checkout HEAD -- backend/igny8_core/auth/serializers.py

# Revert frontend
git checkout HEAD -- frontend/src/components/auth/SignUpForm.tsx

# Remove command file
rm backend/igny8_core/auth/management/commands/create_free_trial_plan.py
```

### If Migration Causes Issues
```bash
# Rollback migration
docker exec igny8_backend python manage.py migrate igny8_core_auth 0006_soft_delete_and_retention
```

---

## Next Steps When Ready to Implement

### Step 1: Test Current Changes
```bash
# Create free trial plan
docker exec igny8_backend python manage.py create_free_trial_plan

# Test signup
# Visit https://app.igny8.com/signup
# Fill form and submit
# Check if account created with 2000 credits
```

### Step 2: If Step 1 Works, Proceed With
1. Create migration 0007 (payment_method fields)
2. Update models with new fields
3. Add validation helper
4. Fix API key authentication
5. Fix throttling
6. Create bank transfer endpoint
7. Add tests

### Step 3: Full System Verification
- Run all tests
- Test all flows from Final_Flow_Tenancy.md
- Monitor production for 24-48 hours
