-## 🏗️ New Architecture Components
+## 🏗️ Architecture Components

-### 1. SeedDataLoader (Core Engine)
+### 1. Direct Database Loading

-**Location**: `services/demo_session/app/services/seed_data_loader.py`
+Each service's `internal_demo.py` endpoint now loads data directly into its database, eliminating the need for:
+- Kubernetes Jobs
+- HTTP-based cloning
+- External orchestration scripts

-**Features**:
- ✅ **Parallel Execution**: 3 workers per phase
- ✅ **Automatic Retry**: 2 attempts with 1s delay
- ✅ **Connection Pooling**: 5 connections reused
- ✅ **Batch Inserts**: 100 records per batch
- ✅ **Dependency Management**: Phase-based loading
+**Example**: `services/orders/app/api/internal_demo.py`

-**Performance Settings**:
+**Key Features**:
+- ✅ **Direct database inserts** - No HTTP overhead
+- ✅ **Transaction safety** - Atomic operations with rollback
+- ✅ **JSON seed data** - Loaded from standardized files
+- ✅ **Shared utilities** - Consistent transformation logic
+
+### 2. Shared Utilities Library
+
+**Location**: `shared/utils/`
+
+Three critical utilities power the new architecture:
+
+#### a) ID Transformation (`demo_id_transformer.py`)
+
+**Purpose**: XOR-based deterministic ID transformation
 ```python
-PERFORMANCE_SETTINGS = {
-    "max_parallel_workers": 3,
-    "connection_pool_size": 5,
-    "batch_insert_size": 100,
-    "timeout_seconds": 300,
-    "retry_attempts": 2,
-    "retry_delay_ms": 1000
-}
+from shared.utils.demo_id_transformer import transform_id
+
+# Transform base ID with tenant ID for isolation
+transformed_id = transform_id(base_id, virtual_tenant_id)
 ```

-### 2. Load Order with Phases
+**Benefits**:
+- ✅ **Deterministic**: Same base ID + tenant ID = same result
+- ✅ **Isolated**: Different tenants get different IDs
+- ✅ **Consistent**: Cross-service relationships preserved

-```yaml
-# Phase 1: Independent Services (Parallelizable)
- tenant (no dependencies)
- inventory (no dependencies)  
- suppliers (no dependencies)
+#### b) Temporal Adjustment (`demo_dates.py`)

-# Phase 2: First-Level Dependencies (Parallelizable)
- auth (depends on tenant)
- recipes (depends on inventory)
+**Purpose**: Dynamic date adjustment relative to session creation
+```python
+from shared.utils.demo_dates import adjust_date_for_demo, resolve_time_marker

-# Phase 3: Complex Dependencies (Sequential)
- production (depends on inventory, recipes)
- procurement (depends on suppliers, inventory, auth)
- orders (depends on inventory)
+# Adjust static seed dates to session time
+adjusted_date = adjust_date_for_demo(original_date, session_created_at)

-# Phase 4: Metadata Services (Parallelizable)
- sales (no database operations)
- orchestrator (no database operations)
- forecasting (no database operations)
+# Support BASE_TS markers for edge cases
+delivery_time = resolve_time_marker("BASE_TS + 2h30m", session_created_at)
 ```

-### 3. Seed Data Profiles
+**Benefits**:
+- ✅ **Temporal determinism**: Data always appears recent
+- ✅ **Edge case support**: Create late deliveries, overdue batches
+- ✅ **Workday handling**: Skip weekends automatically
+
+#### c) Seed Data Paths (`seed_data_paths.py`)
+
+**Purpose**: Unified seed data file location
+```python
+from shared.utils.seed_data_paths import get_seed_data_path
+
+# Find seed data across multiple locations
+json_file = get_seed_data_path("professional", "08-orders.json")
+```
+
+**Benefits**:
+- ✅ **Fallback support**: Multiple search locations
+- ✅ **Enterprise profiles**: Handle parent/child structure
+- ✅ **Clear errors**: Helpful messages when files missing
+
+### 3. Data Loading Flow
+
+The demo session creation follows this sequence:
+
+```mermaid
+graph TD
+    A[Create Demo Session] --> B[Load JSON Seed Data]
+    B --> C[Transform IDs with XOR]
+    C --> D[Adjust Dates to Session Time]
+    D --> E[Insert into Service Databases]
+    E --> F[Return Demo Credentials]
+
+    C --> C1[Base ID + Tenant ID]
+    C1 --> C2[XOR Operation]
+    C2 --> C3[Unique Virtual ID]
+
+    D --> D1[Original Seed Date]
+    D1 --> D2[Calculate Offset]
+    D2 --> D3[Apply to Session Time]
+```
+
+**Key Steps**:
+1. **Session Creation**: Generate virtual tenant ID
+2. **Seed Data Loading**: Read JSON files from `infrastructure/seed-data/`
+3. **ID Transformation**: Apply XOR to all entity IDs
+4. **Temporal Adjustment**: Shift all dates relative to session creation
+5. **Database Insertion**: Direct inserts into service databases
+6. **Response**: Return login credentials and session info
+

-## 🚀 Performance Optimization
+## 🚀 Key Technical Innovations

-### Parallel Loading Strategy
+### 1. XOR-Based ID Transformation

-```
-Phase 1 (Parallel): tenant + inventory + suppliers (3 workers)
-Phase 2 (Parallel): auth + recipes (2 workers)
-Phase 3 (Sequential): production → procurement → orders
-Phase 4 (Parallel): sales + orchestrator + forecasting (3 workers)
-```
+**Problem**: Need unique IDs per virtual tenant while maintaining cross-service relationships

-### Connection Pooling
-
- **Pool Size**: 5 connections
- **Reuse Rate**: 70-80% fewer connection overhead
- **Benefit**: Reduced database connection latency
-
-### Batch Insert Optimization
-
- **Batch Size**: 100 records
- **Reduction**: 50-70% fewer database roundtrips
- **Benefit**: Faster bulk data loading
-
-## 🔄 Migration Guide
-
-### From Legacy to Modern System
-
-**Step 1: Update Tiltfile**
+**Solution**: XOR operation between base ID and tenant ID
 ```python
-# Remove old demo-seed jobs
-# k8s_resource('demo-seed-users-job', ...)
-# k8s_resource('demo-seed-tenants-job', ...)
-# ... (30+ jobs)
-
-# Add new seed-data-loader
-k8s_resource(
-    'seed-data-loader',
-    resource_deps=[
-        'tenant-migration',
-        'auth-migration',
-        # ... other migrations
-    ]
-)
+def transform_id(base_id: UUID, tenant_id: UUID) -> UUID:
+    base_bytes = base_id.bytes
+    tenant_bytes = tenant_id.bytes
+    transformed_bytes = bytes(b1 ^ b2 for b1, b2 in zip(base_bytes, tenant_bytes))
+    return UUID(bytes=transformed_bytes)
 ```

-**Step 2: Update Kustomization**
-```yaml
-# Remove old job references
-# - jobs/demo-seed-*.yaml
+**Benefits**:
+- ✅ **Deterministic**: Same inputs always produce same output
+- ✅ **Reversible**: Can recover original IDs if needed
+- ✅ **Collision-resistant**: Different tenants = different IDs
+- ✅ **Fast**: Simple bitwise operation

-# Add new seed-data-loader
- jobs/seed-data/seed-data-loader-job.yaml
+### 2. Temporal Determinism
+
+**Problem**: Static seed data dates become stale over time
+
+**Solution**: Dynamic date adjustment relative to session creation
+```python
+def adjust_date_for_demo(original_date: datetime, session_time: datetime) -> datetime:
+    offset = original_date - BASE_REFERENCE_DATE
+    return session_time + offset
 ```

-**Step 3: Remove Legacy Code**
-```bash
-# Remove internal_demo.py files
-find services -name "internal_demo.py" -delete
+**Benefits**:
+- ✅ **Always fresh**: Data appears recent regardless of when session created
+- ✅ **Maintains relationships**: Time intervals between events preserved
+- ✅ **Edge case support**: Can create "late deliveries" and "overdue batches"
+- ✅ **Workday-aware**: Automatically skips weekends

-# Comment out HTTP endpoints
-# service.add_router(internal_demo.router)  # REMOVED
+### 3. BASE_TS Markers
+
+**Problem**: Need precise control over edge cases (late deliveries, overdue items)
+
+**Solution**: Time markers in seed data
+```json
+{
+  "delivery_date": "BASE_TS + 2h30m",
+  "order_date": "BASE_TS - 4h"
+}
+```
+
+**Supported formats**:
+- `BASE_TS + 1h30m` - 1 hour 30 minutes ahead
+- `BASE_TS - 2d` - 2 days ago
+- `BASE_TS + 0.5d` - 12 hours ahead
+- `BASE_TS - 1h45m` - 1 hour 45 minutes ago
+
+**Benefits**:
+- ✅ **Precise control**: Exact timing for demo scenarios
+- ✅ **Readable**: Human-friendly format
+- ✅ **Flexible**: Supports hours, minutes, days, decimals
+
+## 🔄 How It Works: Complete Flow
+
+### Step-by-Step Demo Session Creation
+
+1. **User Request**: Frontend calls `/api/v1/demo-sessions` with demo type
+2. **Session Setup**: Demo Session Service:
+   - Generates virtual tenant UUID
+   - Records session metadata
+   - Calculates session creation timestamp
+3. **Parallel Service Calls**: Demo Session Service calls each service's `/internal/demo/clone` endpoint with:
+   - `virtual_tenant_id` - Virtual tenant UUID
+   - `demo_account_type` - Profile (professional/enterprise)
+   - `session_created_at` - Session timestamp for temporal adjustment
+4. **Per-Service Loading**: Each service:
+   - Loads JSON seed data for its domain
+   - Transforms all IDs using XOR with virtual tenant ID
+   - Adjusts all dates relative to session creation time
+   - Inserts data into its database within a transaction
+   - Returns success/failure status
+5. **Response**: Demo Session Service returns credentials and session info
+
+### Example: Orders Service Clone Endpoint
+
+```python
+@router.post("/internal/demo/clone")
+async def clone_demo_data(
+    virtual_tenant_id: str,
+    demo_account_type: str,
+    session_created_at: str,
+    db: AsyncSession = Depends(get_db)
+):
+    try:
+        # Parse session time

+        json_file = get_seed_data_path(demo_account_type, "08-orders.json")
+        with open(json_file, 'r') as f:
+            seed_data = json.load(f)
+
+        # Clone customers
+        for customer_data in seed_data['customers']:

+            last_order = adjust_date_for_demo(
+                customer_data.get('last_order_date'),

+            customer_id = transform_id(order_data['customer_id'], virtual_tenant_id)
+
+            # Handle BASE_TS markers for precise timing
+            delivery_date = resolve_time_marker(
+                order_data.get('delivery_date', 'BASE_TS + 2h'),
+                session_time
+            )
+
+            new_order = CustomerOrder(
+                id=transformed_id,
+                tenant_id=virtual_tenant_id,
+                customer_id=customer_id,
+                requested_delivery_date=delivery_date,
+                ...
+            )
+            db.add(new_order)
+
+        await db.commit()
+        return {"status": "completed", "records_cloned": total}
+
+    except Exception as e:
+        await db.rollback()
+        return {"status": "failed", "error": str(e)}
 ```

 ## 📊 Monitoring and Troubleshooting

-### Logs and Metrics
+### Service Logs
+
+Each service's demo cloning endpoint logs structured data:

 ```bash
-# View job logs
-kubectl logs -n bakery-ia -l app=seed-data-loader -f
+# View orders service demo logs
+kubectl logs -n bakery-ia -l app=orders-service | grep "demo"

-# Check phase durations
-kubectl logs -n bakery-ia -l app=seed-data-loader | grep "Phase.*completed"
+# View all demo session creations
+kubectl logs -n bakery-ia -l app=demo-session-service | grep "cloning"

-# View performance metrics
-kubectl logs -n bakery-ia -l app=seed-data-loader | grep "duration_ms"
+# Check specific session
+kubectl logs -n bakery-ia -l app=demo-session-service | grep "session_id=<uuid>"
 ```

 ### Common Issues

 | Issue | Solution |
 |-------|----------|
-| Job fails to start | Check init container logs for health check failures |
-| Validation errors | Run `python3 validator.py --profile <profile>` |
-| Slow performance | Check phase durations, adjust parallel workers |
-| Missing ID maps | Verify load script outputs, check dependencies |
+| Seed file not found | Check `seed_data_paths.py` search locations, verify file exists |
+| ID transformation errors | Ensure all IDs in seed data are valid UUIDs |
+| Date parsing errors | Verify BASE_TS marker format, check ISO 8601 compliance |
+| Transaction rollback | Check database constraints, review service logs for details |
+| Slow session creation | Check network latency to databases, review parallel call performance |

 ## 🎓 Best Practices

-### Data Management
- ✅ **Always validate** before loading: `validator.py --strict`
- ✅ **Use generators** for new data: `generate_*.py` scripts
- ✅ **Test in staging** before production deployment
- ✅ **Monitor performance** with phase duration logs
+### Adding New Seed Data

-### Development
- ✅ **Start with professional** profile for simpler testing
- ✅ **Use Tilt** for local development and testing
- ✅ **Check logs** for detailed timing information
- ✅ **Update documentation** when adding new features
+1. **Update JSON files** in `infrastructure/seed-data/`
+2. **Use valid UUIDs** for all entity IDs
+3. **Use BASE_TS markers** for time-sensitive data:
+   ```json
+   {
+     "delivery_date": "BASE_TS + 2h30m",  // For edge cases
+     "order_date": "2025-01-15T10:00:00Z"  // Or ISO 8601 for general dates
+   }
+   ```
+4. **Validate data** with `validator.py --profile <profile> --strict`
+5. **Test locally** with Tilt before committing

-### Production
- ✅ **Deploy to staging** first for validation
- ✅ **Monitor job completion** times
- ✅ **Set appropriate TTL** for cleanup (default: 24h)
- ✅ **Use strict validation** mode for production
+### Implementing Service Cloning
+
+When adding demo support to a new service:
+
+1. **Create `internal_demo.py`** in `app/api/`
+2. **Import shared utilities**:
+   ```python
+   from shared.utils.demo_id_transformer import transform_id
+   from shared.utils.demo_dates import adjust_date_for_demo, resolve_time_marker
+   from shared.utils.seed_data_paths import get_seed_data_path
+   ```
+3. **Load JSON seed data** for your service
+4. **Transform all IDs** using `transform_id()`
+5. **Adjust all dates** using `adjust_date_for_demo()` or `resolve_time_marker()`
+6. **Handle cross-service refs** - transform foreign key UUIDs too
+7. **Use transactions** - commit on success, rollback on error
+8. **Return structured response**:
+   ```python
+   return {
+       "service": "your-service",
+       "status": "completed",
+       "records_cloned": count,
+       "duration_ms": elapsed
+   }
+   ```
+
+### Production Deployment
+
+- ✅ **Validate seed data** before deploying changes
+- ✅ **Test in staging** with both profiles
+- ✅ **Monitor session creation times** in production
+- ✅ **Check error rates** for cloning endpoints
+- ✅ **Review database performance** under load

 ## 🔧 Technical Details

-### ID Mapping System
+### XOR ID Transformation Details

-The new system uses a **type-safe ID mapping registry** that automatically handles cross-service references:
+The XOR-based transformation provides mathematical guarantees:

 ```python
-# Old system: Manual ID mapping via HTTP headers
-# POST /internal/demo/tenant
-# Response: {"tenant_id": "...", "mappings": {...}}
+# Property 1: Deterministic
+transform_id(base_id, tenant_A) == transform_id(base_id, tenant_A)  # Always true

-# New system: Automatic ID mapping via IDMapRegistry
-id_registry = IDMapRegistry()
-id_registry.register("tenant_ids", {"base_tenant": actual_tenant_id})
-temp_file = id_registry.create_temp_file("tenant_ids")
-# Pass to dependent services via --tenant-ids flag
+# Property 2: Isolation
+transform_id(base_id, tenant_A) != transform_id(base_id, tenant_B)  # Always true
+
+# Property 3: Reversible
+base_id == transform_id(transform_id(base_id, tenant), tenant)  # XOR is self-inverse
+
+# Property 4: Preserves relationships
+customer_id = transform_id(base_customer, tenant)
+order_id = transform_id(base_order, tenant)
+# Order's customer_id reference remains valid after transformation
+```
+
+### Temporal Adjustment Algorithm
+
+```python
+# Base reference date (seed data "day zero")
+BASE_REFERENCE_DATE = datetime(2025, 1, 15, 6, 0, 0, tzinfo=timezone.utc)
+
+# Session creation time
+session_time = datetime(2025, 12, 14, 10, 30, 0, tzinfo=timezone.utc)
+
+# Original seed date (BASE_REFERENCE + 3 days)
+original_date = datetime(2025, 1, 18, 14, 0, 0, tzinfo=timezone.utc)
+
+# Calculate offset from base
+offset = original_date - BASE_REFERENCE_DATE  # 3 days, 8 hours
+
+# Apply to session time
+adjusted_date = session_time + offset  # 2025-12-17 18:30:00 UTC
+# Result: Maintains the 3-day, 8-hour offset from session creation
 ```

 ### Error Handling

-Comprehensive error handling with automatic retries:
+Each service cloning endpoint uses transaction-safe error handling:

 ```python
-for attempt in range(retry_attempts + 1):
-    try:
-        result = await load_service_data(...)
-        if result.get("success"):
-            return result
-        else:
-            await asyncio.sleep(retry_delay_ms / 1000)
-    except Exception as e:
-        logger.warning(f"Attempt {attempt + 1} failed: {e}")
-        await asyncio.sleep(retry_delay_ms / 1000)
+try:
+    # Load and transform data
+    for entity in seed_data:
+        transformed = transform_entity(entity, virtual_tenant_id, session_time)
+        db.add(transformed)
+
+    # Atomic commit
+    await db.commit()
+
+    return {"status": "completed", "records_cloned": count}
+
+except Exception as e:
+    # Automatic rollback on any error
+    await db.rollback()
+    logger.error("Demo cloning failed", error=str(e), exc_info=True)
+
+    return {"status": "failed", "error": str(e)}
 ```
