1. ARCHITECTURE OVERVIEW

1.1 Core Principles

Principle	Description	Implementation
Domain-Driven Design	Organize by business domains, not technical layers	domain/ folder with content, planning, linking, optimization, publishing domains
Service Layer Pattern	Business logic in services, not ViewSets	All modules delegate to domain services
Single Responsibility	Each layer has one clear purpose	Core → Domain → Module → Infrastructure
No Duplication	Reuse services across modules	ContentGenerationService used by Writer + Site Builder
Multi-Tenancy First	All features respect account/site/sector boundaries	All models inherit AccountBaseModel or SiteSectorBaseModel
Automation Ready	All functions can be automated via Celery	All AI functions exposed as Celery tasks with scheduling support

1.2 System Boundaries

System	Purpose	Technology	Container
IGNY8 Core App	Main backend API (all domains)	Django 5.2+	igny8_backend
IGNY8 Main App	Dashboard UI	React 19 + Vite	igny8_frontend
IGNY8 Site Builder	Site creation wizard	React 19 + Vite	igny8_site_builder (NEW)
IGNY8 Sites	Public site renderer	React 19 + Vite/Next.js	igny8_sites (NEW)
IGNY8 Marketing	Marketing website	React 19 + Vite	igny8_marketing_dev (can merge with Sites)
Celery Workers	Async task processing	Celery + Redis	igny8_celery_worker
Celery Beat	Scheduled automation	Celery Beat	igny8_celery_beat

---

2. CONTAINER ARCHITECTURE

2.1 Container Structure

Container	Port	Purpose	Volumes	Dependencies
igny8_backend	8011:8010	Django API server	/data/app/igny8/backend:/app, /data/app/logs:/app/logs, /data/app/storage:/app/storage	postgres, redis
igny8_frontend	8021:5173	Main app UI (dev)	/data/app/igny8/frontend:/app	igny8_backend
igny8_site_builder	8022:5175	Site Builder UI (NEW)	/data/app/igny8/site-builder:/app	igny8_backend
igny8_sites	8024:5176	Sites renderer (NEW)	/data/app/igny8/sites:/app, /data/app/sites-data:/sites	igny8_backend
igny8_marketing_dev	8023:5174	Marketing site	/data/app/igny8/frontend:/app	igny8_backend
igny8_celery_worker	-	Async tasks	/data/app/igny8/backend:/app, /data/app/logs:/app/logs	postgres, redis
igny8_celery_beat	-	Scheduled tasks	/data/app/igny8/backend:/app, /data/app/logs:/app/logs	postgres, redis

2.2 Volume Strategy

Volume Path	Purpose	Mount Type	Backup Strategy
/data/app/igny8/backend	Backend code (dev)	Bind mount (rw)	Git repo
/data/app/igny8/frontend	Frontend code (dev)	Bind mount (rw)	Git repo
/data/app/igny8/site-builder	Site Builder code (NEW)	Bind mount (rw)	Git repo
/data/app/igny8/sites	Sites renderer code (NEW)	Bind mount (rw)	Git repo
/data/app/storage	Generated files, images	Named volume	Daily backup
/data/app/sites-data	Rendered site files (NEW)	Named volume	Daily backup
/data/app/logs	Application logs	Named volume	Rotate weekly
/data/app/cache	Redis cache (optional)	Named volume	No backup

Volume Improvements:

• Use named volumes for data (storage, sites-data, logs) - better performance, easier backup
• Use bind mounts only for code (development)
• Production: Use named volumes for all, code deployed via images

---

6. MULTI-SITE MANAGEMENT

6.1 Site Isolation Strategy

Aspect	Implementation	Purpose
Database Filtering	All models inherit AccountBaseModel/SiteSectorBaseModel	Automatic site isolation
API Filtering	ViewSets use base classes	Automatic filtering by site_id
Storage Isolation	/data/app/storage/{site_id}/	Separate storage per site
Site-Specific Limits	Plan limits enforced per site	Prevent one site from overwhelming system
Queue Isolation	Celery queues per site (optional)	Prevent site blocking
Rate Limiting	Per-site rate limits	Prevent abuse

6.2 Site Resource Management

Resource	Limit Type	Enforcement	Location
Daily Content Tasks	Per site	Plan.daily_content_tasks	domain/content/services/content_generation_service.py
Daily AI Requests	Per site	Plan.daily_ai_requests	infrastructure/ai/engine.py
Monthly Word Count	Per site	Plan.monthly_word_count_limit	domain/content/services/content_generation_service.py
Daily Image Generation	Per site	Plan.daily_image_generation_limit	infrastructure/ai/functions/generate_images.py
Storage Quota	Per site	Configurable (default: 10GB)	infrastructure/storage/file_storage.py
Concurrent Tasks	Per site	Configurable (default: 5)	Celery queue configuration

6.3 Site Performance Optimization

Optimization	Implementation	Benefit
Database Indexing	Indexes on site_id, sector_id, account_id	Faster queries
Query Optimization	select_related(), prefetch_related()	Reduce DB queries
Caching	Redis cache per site	Faster responses
Background Processing	Celery for heavy operations	Non-blocking
Resource Throttling	Per-site rate limits	Prevent overload

7. VOLUME & STORAGE STRATEGY

7.1 Volume Structure

/data/app/
├── igny8/                         # Code (bind mount, git repo)
│   ├── backend/
│   ├── frontend/
│   ├── site-builder/             # NEW
│   └── sites/                     # NEW
│
├── storage/                       # Named volume (data)
│   ├── {site_id}/
│   │   ├── images/
│   │   ├── content/
│   │   └── exports/
│   └── shared/
│       └── templates/
│
├── sites-data/                    # Named volume (NEW - rendered sites)
│   ├── marketing/
│   └── clients/
│       ├── {site_id}/
│       │   └── v{version}/
│       │       ├── site.json
│       │       ├── pages/

│   └── nginx/
│
└── cache/                         # Named volume (optional)
    └── redis/

7.2 Volume Mounting Strategy

Volume	Type	Purpose	Backup
Code directories	Bind mount (dev) / Image (prod)	Source code	Git repo
storage/	Named volume	Generated files, images	Daily backup
sites-data/	Named volume	Rendered site files	Daily backup
logs/	Named volume	Application logs	Weekly rotation
cache/	Named volume	Redis cache	No backup

7.3 Storage Service Implementation

# infrastructure/storage/file_storage.py
class FileStorageService:
    def get_site_storage_path(self, site_id: int) -> str:
        return f"/data/app/storage/{site_id}/"
    
    def get_site_quota(self, site_id: int) -> int:
        # Get from Plan or Site model
        return site.plan.storage_quota_gb * 1024 * 1024 * 1024
    
    def check_quota(self, site_id: int, file_size: int) -> bool:
        current_size = self.get_site_storage_size(site_id)
        quota = self.get_site_quota(site_id)
        return (current_size + file_size) <= quota

10. CREDIT-BASED USAGE SYSTEM

10.1 Core Principle

Credit-Only Model: All features are unlimited. Only credits restrict usage.

• ✅ All features unlocked for paid users
• ✅ No plan-based limits (keywords, clusters, tasks, etc.)
• ✅ Only credits control usage
• ✅ Operational limits only (50 keywords/request, 6 images/request)

10.2 Plan Model (Simplified)

Field	Type	Purpose
monthly_credits	Integer	Credits added per month
support_level	CharField	Support tier (basic, priority, enterprise)
billing_cycle	CharField	'monthly' or 'annual'
price	Decimal	Subscription price
features	JSONField	Feature flags (for future use)

REMOVED FIELDS (no longer needed):

• max_keywords, max_clusters, max_content_ideas
• daily_content_tasks, monthly_word_count_limit
• daily_image_generation_limit, monthly_image_count
• All other usage limits

10.3 Credit Cost Structure

Operation	Credit Cost	Type	Notes
Clustering	10 credits	Fixed	Per clustering request
Idea Generation	15 credits	Fixed	Per cluster → ideas request
Content Generation	1 credit per 100 words	Variable	Based on word count
Image Generation	5 credits	Fixed	Per image (user sees batch)
Image Prompt Extraction	2 credits	Fixed	Per content piece
Linking	8 credits	Fixed	Per content piece (NEW)
Optimization	1 credit per 200 words	Variable	Per content piece (NEW)
Site Structure Generation	50 credits	Fixed	Per site blueprint (NEW)
Site Page Generation	20 credits	Fixed	Per page (NEW)

10.4 Credit Enforcement

Location	Check	Implementation
AI Engine	Before AI call	infrastructure/ai/engine.py - Check credits, deduct before request
Content Generation	Before generation	domain/content/services/content_generation_service.py
Image Generation	Before generation	infrastructure/ai/functions/generate_images.py
Linking	Before linking	domain/linking/services/linker_service.py (NEW)
Optimization	Before optimization	domain/optimization/services/optimizer_service.py (NEW)
Site Building	Before structure gen	domain/site_building/services/structure_generation_service.py (NEW)

10.5 Credit Logging

Log Type	Fields	Purpose
CreditUsageLog	account, operation_type, credits_used, related_object_type, related_object_id, metadata	Track all credit consumption
CreditTransaction	account, transaction_type, amount, description	Track credit additions/deductions

Usage Tracking:

• Total credits used (account level)
• Credits per operation type (clustering, content, images, etc.)
• Credits per site (site level breakdown)
• Credits per user (user level breakdown)
• Historical usage trends

10.6 Operational Limits (Technical Constraints)

Limit	Value	Type	Reason
Keywords per request	50	Technical	API payload size, processing time
Images per request	6	Technical	Queue management (user sees as batch)
Images per AI call	1	Technical	Image API limitation (internal)

These are NOT business limits - they're technical constraints for request processing.

Credit Check	Before every AI operation	domain/billing/services/credit_service.py
Credit Deduction	After successful operation	domain/billing/services/credit_service.py

platform_type	CharField	Type: 'cms', 'ecommerce', 'custom_api'
config_json	JSONField	Platform-specific configuration
credentials	EncryptedField	Encrypted API keys, tokens, passwords
is_active	Boolean	Enable/disable integration
sync_enabled	Boolean	Enable two-way sync
last_sync_at	DateTime	Last successful sync

Purpose:

• Sites can be NEW (built via Site Builder) or EXISTING (already integrated)
• One site can have multiple integrations (WordPress + Shopify)
• Integration credentials stored securely
• Two-way sync support

11.2 Site Types & Hosting

Site Type	Description	Integration	Hosting
NEW Site (IGNY8 Built)	Created via Site Builder	None initially	IGNY8 Sites renderer
EXISTING WordPress	Already has WordPress site	WordPress integration	WordPress hosting
EXISTING Shopify	Already has Shopify store	Shopify integration	Shopify hosting
EXISTING Custom	Custom platform/API	Custom integration	External hosting
Hybrid	Built in IGNY8, also integrated	Multiple integrations	IGNY8 + External

11.3 Site Builder Structure

Site Builder Flow:
1. User creates SiteBlueprint (via wizard)
2. SiteBlueprint.hosting_type = 'igny8_sites' | 'wordpress' | 'shopify' | 'multi'
3. If 'wordpress' or 'shopify':
   - User must configure SiteIntegration first
   - Site Builder generates content compatible with platform
4. If 'igny8_sites':
   - Site deployed to Sites renderer
5. If 'multi':
   - Site can publish to multiple destinations

11.4 Multi-Destination Publishing

Content Type	Can Publish To	Implementation
Blog Posts	WordPress, IGNY8 Sites, Shopify Blog	PublisherService routes to adapters
Pages	WordPress, IGNY8 Sites, Shopify Pages	PublisherService routes to adapters
Products	Shopify, WooCommerce (WordPress), IGNY8 Sites	Product adapter per platform
Categories	WordPress, Shopify Collections, IGNY8 Sites	Taxonomy adapter per platform
Site Blueprint	IGNY8 Sites, WordPress (via plugin), Shopify (future)	DeploymentService routes to adapters

Publishing Flow:

# Single content can publish to multiple destinations
publisher_service.publish(
    content=content,
    destinations=['wordpress', 'igny8_sites', 'shopify']  # Multiple destinations
)

11.5 Integration Adapters

Adapter	Platform	Purpose	Implementation
WordPressAdapter	WordPress	Publish content, sync status	Uses WordPress REST API
SitesRendererAdapter	IGNY8 Sites	Deploy site blueprints	Uploads to Sites container
ShopifyAdapter	Shopify	Publish products, pages, blog	Uses Shopify Admin API
BaseAdapter	Abstract	Common interface	All adapters inherit

11.6 Site Integration Service

# domain/integration/services/integration_service.py
class IntegrationService:
    def create_integration(self, site, platform, config, credentials):
        """Create new site integration"""
    
    def test_integration(self, integration):
        """Test integration connection"""
    
    def sync_site_data(self, integration, sync_type='full'):
        """Sync site data from external platform"""
        # Full: All posts/products
        # Incremental: Only changes since last sync
    
    def get_available_platforms(self):
        """Get list of supported platforms"""
        return ['wordpress', 'shopify', 'custom_api']

11.7 Site Model Extensions

Field	Type	Purpose
site_type	CharField	'new', 'existing', 'hybrid'
hosting_type	CharField	'igny8_sites', 'wordpress', 'shopify', 'custom', 'multi'
integrations	ManyToMany(SiteIntegration)	Multiple integrations per site

Current Site Model (needs extension):

• Already has: wp_url, wp_username, wp_app_password (WordPress specific)
• NEW: Move to SiteIntegration model for flexibility
• NEW: Add site_type and hosting_type fields

11.8 Publishing Workflow

Content/Site Publishing Flow:

1. User selects content/site to publish
2. System checks Site.integrations (available destinations)
3. User selects destinations (can be multiple)
4. PublisherService routes to appropriate adapters:
   - WordPressAdapter.publish()
   - SitesRendererAdapter.deploy()
   - ShopifyAdapter.publish()
5. PublishingRecord created for each destination
6. Status tracked per destination
7. Two-way sync enabled if integration.sync_enabled = True

11.10 Site Builder Integration Flow

Site Builder → Publishing Flow:

1. User builds site via Site Builder wizard
2. SiteBlueprint created with hosting_type
3. If hosting_type = 'wordpress' or 'shopify':
   a. User must configure SiteIntegration
   b. Site Builder generates platform-compatible structure
4. User clicks "Deploy"
5. DeploymentService:
   - If 'igny8_sites': Deploy to Sites renderer
   - If 'wordpress': Publish via WordPressAdapter
   - If 'shopify': Publish via ShopifyAdapter
   - If 'multi': Publish to all configured destinations
6. DeploymentRecord created
7. Site available on selected platforms

SUMMARY

Key Architectural Decisions

1. Domain-Driven Structure: Organize by business domains, not technical layers
2. Service Layer: All business logic in services, ViewSets are thin
3. Unified Content Model: Extend existing Content model, don't create duplicates
4. Automation First: All functions can be automated via Celery + AutomationRule
5. Multi-Site Ready: All features respect site boundaries and limits
6. Volume Strategy: Named volumes for data, bind mounts for code (dev)
7. Single Repository: Keep all code in one repo with clear structure
8. Container Separation: Separate containers for different UIs (Main, Site Builder, Sites)

Implementation Order

1. Phase 0: Foundation (Service layer, Automation, Model extensions)
2. Phase 1: Site Builder
3. Phase 2: Linker & Optimizer
4. Phase 3: Sites Renderer
5. Phase 4: Universal Content Types

Success Criteria

• ✅ No code duplication
• ✅ All functions automatable
• ✅ Multi-site isolation working
• ✅ Limits enforced per site
• ✅ Volume strategy optimized
• ✅ Repository structure clean
• ✅ All placeholders implemented
