Tenancy System Implementation Summary

Complete Context for Future Implementation

Date: 2025-12-08
Status: Analysis Complete, Ready for Implementation

---

What I've Done (Context Gathering)

1. Analyzed Documentation

• ✅ Read Tenancy_Audit_Report.md - Gap analysis
• ✅ Read audit_fixes.md - Previous recommendations
• ✅ Read 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
• ✅ Read all migrations (0001-0006)

3. Queried Database (via Docker)

• ✅ Found 5 existing plans (free, starter, growth, scale, enterprise)
• ✅ Found 8 accounts, all using existing plans
• ✅ Found 280+ credit transactions (system actively used)
• ✅ Confirmed NO subscriptions exist

Code Changes Made (Review Before Using)

⚠️ Backend Changes (Review First)

1. 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

   • 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
   • 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

# 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

# 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

# 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

• Middleware validation works
• AI operations work

⚠️ Needs Enhancement

• Payment method tracking (add fields)
• API key validation (add check)
• Registration credit seeding (deploy fix)
• Throttling enforcement (tighten rules)
• Bank transfer workflow (add endpoint)

📊 Database is Healthy
