✅ wordpress/      - WP installation & config
✅ environments/   - Dev/stage/prod environments
✅ staging/        - Staging workflow
✅ backups/        - Backup/restore operations
✅ billing/        - Subscription & invoicing
✅ payments/       - Payment processing
✅ nodes/          - Server/node management
✅ sessions/       - Session management

Modules (Supporting Features - 8 modules):

✅ auth/           - Authentication & tokens
✅ users/          - User management
✅ teams/          - Team/tenant management

🔧 Environment Configuration Analysis¶

Current State: Scattered Configuration¶

Issue: Environment files exist in multiple locations: - /env/ - Template examples (3 files) - /backend/.env - Active backend config - env/backend-local.example - Template - Root level .env expected by docker-compose

Environment File Comparison¶

Variable	/env/backend-local.example	backend/app/core/config.py	Status
APP_ENV	✅ `local`	✅ `app_env`	Match
DB_HOST	✅ `db`	✅ `db_host`	Match
DB_PORT	✅ `5432`	✅ `db_port`	Match
DB_NAME	✅ `mbpanel_local`	✅ `db_name`	Match
DB_USER	✅ `mbpanel_local`	✅ `db_user`	Match
DB_PASSWORD	✅ `local_password`	✅ `db_password`	Match
RABBITMQ_URL	✅ Present	✅ `rabbitmq_url`	Match
REDIS_URL	✅ `redis://redis:6379/0`	✅ `redis_url`	Match
ENCRYPTION_KEY	✅ Empty (needs value)	✅ `encryption_key`	Match
BACKEND_CORS_ORIGINS	✅ `http://localhost:3000`	❌ Missing	ADD
VZ_VIRTUOZZO_BASE_URL	✅ Present	❌ Missing	ADD
VZ_VIRTUOZZO_SIGNIN_URL	✅ Present	❌ Missing	ADD
VZ_VIRTUOZZO_TIMEOUT_SECONDS	✅ `15`	❌ Missing	ADD

Missing Config Variables in backend/app/core/config.py¶

# Virtuozzo API (from /env templates but missing in config.py)
VZ_VIRTUOZZO_BASE_URL: str = "https://app.mymightybox.io/1.0"
VZ_VIRTUOZZO_SIGNIN_URL: str = "https://app.mymightybox.io/1.0/users/authentication/rest/signin"
VZ_VIRTUOZZO_TIMEOUT_SECONDS: int = 15

# CORS (partially missing)
backend_cors_origins: str = "http://localhost:3000"  # EXISTS BUT NOT IN /env template

Recommendation: ✅ Config.py is more complete than /env templates. Update /env templates to match config.py.

📊 Observability Infrastructure Assessment¶

🧪 Testing Infrastructure¶

Current State¶

backend/tests/
├── __init__.py          ✅ Present
├── conftest.py          ⚠️ Needs fixtures
├── unit/                ✅ Directory exists
│   └── (empty)          ❌ No unit tests yet
└── integration/         ✅ Directory exists
    └── (empty)          ❌ No integration tests yet

What's Needed for Examples¶

1. Unit Test Examples (Need at least 1-2 domains):

# backend/tests/unit/test_domains_sites.py
from app.domains.sites.domain import Site
from app.domains.sites.service import SiteService
from app.domains.sites.schemas import SiteCreate

# Test domain logic, validation, business rules

2. Integration Test Examples (Need at least 1-2 routers):

# backend/tests/integration/test_api_sites.py
from fastapi.testclient import TestClient
from app.main import app

# Test HTTP endpoints with TestClient

3. Fixtures Needed (conftest.py):

# backend/tests/conftest.py
@pytest.fixture
def test_db():
    # Test database setup

@pytest.fixture
def test_client():
    # FastAPI TestClient setup

@pytest.fixture
def mock_user_service():
    # Mock service for dependency overrides

🚀 API Examples Needed for Observability¶

To properly demonstrate observability features, you need working API endpoints. Currently, all domains exist but may be stubs.

Minimum Viable Examples (for observability demo)¶

Recommended: Implement 2-3 complete endpoints:

Sites Domain (Primary):

POST /api/v1/sites/        - Create site (shows: tracing, error capture, audit)
GET  /api/v1/sites/{id}    - Get site (shows: caching, performance)
DELETE /api/v1/sites/{id}  - Delete site (shows: audit logging, security)

Users Module (Secondary):

POST /api/v1/users/register  - Register user (shows: PII filtering, security)
GET  /api/v1/users/me        - Get current user (shows: auth context)

Health Endpoints (Already exist, need enhancement):

GET /api/v1/health           - Basic health ✅
GET /api/v1/health/ready     - K8s readiness ❌
GET /api/v1/health/live      - K8s liveness ❌

Why These? - Sites is your primary domain → best for demonstrating core patterns - Users shows auth/security → demonstrates PII filtering and security monitoring - Health endpoints → required for production deployment

Current Status: - ✅ Domain structure exists - ❌ Need actual database models - ❌ Need service implementations - ❌ Need router implementations with proper error handling

🎬 Next Steps¶

Option 1: Observability First (Recommended for Production Readiness)¶

Timeline: 8-12 hours 1. Implement Sentry core (2h) 2. Complete health checks (1h) 3. Add metrics module (2h) 4. Implement audit logging (2h) 5. Add PII filtering (2h) 6. Create basic example API (3h)

Option 2: Example Domain First (Recommended for Development)¶

Timeline: 6-8 hours 1. Complete Sites domain implementation (3h) 2. Add integration tests (2h) 3. Add Sentry integration to Sites (1h) 4. Add audit logging to Sites (1h) 5. Create testing fixtures (1h)

Option 3: Hybrid Approach (Recommended)¶

Timeline: 10-14 hours 1. Install missing deps (psutil) (15min) 2. Consolidate env files (30min) 3. Complete Sites domain with DB models (3h) 4. Implement Sentry core + integrate with Sites (2h) 5. Complete health checks (1h) 6. Add audit logging + integrate with Sites (2h) 7. Create test fixtures and examples (2h)

✅ Summary¶

Overall Project Health: 8/10

Strengths: - Excellent architecture alignment with DDD principles - Proper separation of concerns - Good documentation - Docker setup ready - Modern tech stack

Areas for Improvement: - Missing observability infrastructure (critical for production) - Need example implementations (critical for testing observability) - Testing infrastructure needs examples - Environment consolidation

Critical Path to Production: 1. Implement observability (Sentry + health + metrics) 2. Complete 1-2 example domains with tests 3. Add security compliance (PII filtering + audit) 4. Set up monitoring/alerting

Recommendation: Follow Option 3 (Hybrid Approach) - Implement one complete domain (Sites) alongside core observability features. This gives you: - Working examples for testing - Production-ready monitoring - Testing patterns established - Clear path forward for other domains
