+# Phase 5: Entity Deletions Through Sacred Pipeline - COMPLETE
+
+**Status:** ✅ Complete  
+**Date:** 2025-11-08  
+**Phase:** 5 of 5 (Sacred Pipeline Entity Operations)
+
+## Overview
+
+Successfully implemented entity deletion functionality through the Sacred Pipeline for all entity types (Parks, Rides, Companies, RideModels). All DELETE operations now flow through the ContentSubmission → Moderation → Approval workflow, completing the Sacred Pipeline implementation for CRUD operations.
+
+## Previous Phases
+
+- ✅ **Phase 1**: Sacred Pipeline foundation fixes (submission types, polymorphic approval)
+- ✅ **Phase 2**: Entity submission services (BaseEntitySubmissionService with create/update methods)
+- ✅ **Phase 3**: Entity creation (POST endpoints use submission services)
+- ✅ **Phase 4**: Entity updates (PUT/PATCH endpoints use submission services)
+- ✅ **Phase 5**: Entity deletions (DELETE endpoints use submission services) - **THIS PHASE**
+
+## Deletion Strategy Implemented
+
+### Soft Delete (Default)
+**Entities with status field:** Park, Ride
+- Sets entity status to 'closed'
+- Preserves data in database for audit trail
+- Can be restored by changing status
+- Maintains relationships and history
+- Default behavior for entities with status fields
+
+### Hard Delete
+**Entities without status field:** Company, RideModel
+- Removes entity from database completely
+- More destructive, harder to reverse
+- Used when entity has no status field for soft delete
+- May break foreign key relationships (consider cascading)
+
+### Implementation Logic
+```python
+# Entities WITH status field (Park, Ride)
+deletion_type='soft'  # Sets status='closed'
+
+# Entities WITHOUT status field (Company, RideModel)
+deletion_type='hard'  # Removes from database
+```
+
+## Changes Made
+
+### 1. BaseEntitySubmissionService (`apps/entities/services/__init__.py`)
+
+Added `delete_entity_submission()` method:
+
+```python
+@classmethod
+@transaction.atomic
+def delete_entity_submission(cls, entity, user, **kwargs):
+    """
+    Delete (or soft-delete) an existing entity through Sacred Pipeline.
+    
+    Args:
+        entity: Existing entity instance to delete
+        user: User requesting the deletion
+        **kwargs: deletion_type, deletion_reason, source, ip_address, user_agent
+    
+    Returns:
+        tuple: (ContentSubmission, deletion_applied: bool)
+    """
+```
+
+**Key Features:**
+- Supports both soft and hard delete
+- Creates entity snapshot for potential restoration
+- Non-moderators restricted to soft delete only
+- Moderators can perform hard delete
+- Creates ContentSubmission with type='delete'
+- Stores deletion metadata (type, reason, snapshot)
+- Moderator bypass: immediate application
+- Regular users: submission enters moderation queue
+
+### 2. ModerationService (`apps/moderation/services.py`)
+
+Updated `approve_submission()` to handle deletion approval:
+
+```python
+elif submission.submission_type == 'delete':
+    deletion_type = submission.metadata.get('deletion_type', 'soft')
+    
+    if deletion_type == 'soft':
+        # Soft delete: Apply status change to 'closed'
+        for item in items:
+            if item.field_name == 'status':
+                setattr(entity, 'status', 'closed')
+            item.approve(reviewer)
+        entity.save()
+    else:
+        # Hard delete: Remove from database
+        for item in items:
+            item.approve(reviewer)
+        entity.delete()
+```
+
+**Handles:**
+- Soft delete: Sets status='closed', saves entity
+- Hard delete: Removes entity from database
+- Marks all submission items as approved
+- Logs deletion type and entity ID
+
+### 3. DELETE Endpoints Updated
+
+#### Parks (`api/v1/endpoints/parks.py`)
+```python
+@router.delete("/{park_id}",
+    response={200: dict, 202: dict, 404: ErrorResponse, 400: ErrorResponse, 401: ErrorResponse})
+@require_auth
+def delete_park(request, park_id: UUID):
+    submission, deleted = ParkSubmissionService.delete_entity_submission(
+        entity=park,
+        user=user,
+        deletion_type='soft',  # Park has status field
+        ...
+    )
+```
+
+#### Rides (`api/v1/endpoints/rides.py`)
+```python
+@router.delete("/{ride_id}",
+    response={200: dict, 202: dict, 404: ErrorResponse, 400: ErrorResponse, 401: ErrorResponse})
+@require_auth
+def delete_ride(request, ride_id: UUID):
+    submission, deleted = RideSubmissionService.delete_entity_submission(
+        entity=ride,
+        user=user,
+        deletion_type='soft',  # Ride has status field
+        ...
+    )
+```
+
+#### Companies (`api/v1/endpoints/companies.py`)
+```python
+@router.delete("/{company_id}",
+    response={200: dict, 202: dict, 404: ErrorResponse, 400: ErrorResponse, 401: ErrorResponse})
+@require_auth
+def delete_company(request, company_id: UUID):
+    submission, deleted = CompanySubmissionService.delete_entity_submission(
+        entity=company,
+        user=user,
+        deletion_type='hard',  # Company has NO status field
+        ...
+    )
+```
+
+#### RideModels (`api/v1/endpoints/ride_models.py`)
+```python
+@router.delete("/{model_id}",
+    response={200: dict, 202: dict, 404: ErrorResponse, 400: ErrorResponse, 401: ErrorResponse})
+@require_auth
+def delete_ride_model(request, model_id: UUID):
+    submission, deleted = RideModelSubmissionService.delete_entity_submission(
+        entity=model,
+        user=user,
+        deletion_type='hard',  # RideModel has NO status field
+        ...
+    )
+```
+
+## API Response Patterns
+
+### Moderator Response (200)
+```json
+{
+  "message": "Park deleted successfully",
+  "entity_id": "uuid",
+  "deletion_type": "soft"
+}
+```
+
+### Regular User Response (202)
+```json
+{
+  "submission_id": "uuid",
+  "status": "pending",
+  "message": "Park deletion request pending moderation. You will be notified when it is approved.",
+  "entity_id": "uuid"
+}
+```
+
+### Error Responses
+- **400**: ValidationError, deletion failed
+- **401**: Authentication required
+- **404**: Entity not found
+
+## Deletion Flow
+
+### For Moderators
+1. User makes DELETE request with authentication
+2. `delete_entity_submission()` creates ContentSubmission
+3. Moderator bypass activates immediately
+4. ModerationService approves submission
+5. Deletion applied (soft or hard based on entity type)
+6. Returns 200 with deletion confirmation
+7. Entity marked as deleted (or removed from database)
+
+### For Regular Users
+1. User makes DELETE request with authentication
+2. `delete_entity_submission()` creates ContentSubmission
+3. Submission enters 'pending' status
+4. Returns 202 with submission ID
+5. Moderator reviews submission later
+6. On approval: deletion applied
+7. User notified via email
+
+## Submission Metadata
+
+Stored in `ContentSubmission.metadata`:
+```python
+{
+    'entity_type': 'park',
+    'entity_id': 'uuid',
+    'entity_name': 'Cedar Point',
+    'deletion_type': 'soft',  # or 'hard'
+    'deletion_reason': 'User-provided reason',
+    'entity_snapshot': {
+        # Complete entity field values for restoration
+        'name': 'Cedar Point',
+        'park_type': 'theme_park',
+        'status': 'operating',
+        ...
+    }
+}
+```
+
+## Submission Items
+
+For soft delete:
+```python
+[
+    {
+        'field_name': 'status',
+        'field_label': 'Status',
+        'old_value': 'operating',
+        'new_value': 'closed',
+        'change_type': 'modify'
+    },
+    {
+        'field_name': '_deletion_marker',
+        'field_label': 'Deletion Request',
+        'old_value': 'active',
+        'new_value': 'closed',
+        'change_type': 'modify'
+    }
+]
+```
+
+For hard delete:
+```python
+[
+    {
+        'field_name': '_deletion_marker',
+        'field_label': 'Deletion Request',
+        'old_value': 'active',
+        'new_value': 'deleted',
+        'change_type': 'remove'
+    }
+]
+```
+
+## Security & Permissions
+
+### Authentication Required
+All DELETE endpoints require authentication via `@require_auth` decorator.
+
+### Moderator Privileges
+- Can perform both soft and hard deletes
+- Deletions applied immediately (bypass moderation)
+- Hard delete restricted to moderators only
+
+### Regular User Restrictions
+- Can only request soft deletes
+- All deletion requests enter moderation queue
+- Hard delete attempts downgraded to soft delete
+- Email notification on approval/rejection
+
+## Logging
+
+Comprehensive logging throughout deletion process:
+
+```python
+# Deletion request
+logger.info(f"Park deletion request: entity={park.id}, user={user.email}, type=soft")
+
+# Submission created
+logger.info(f"Park deletion submission created: {submission.id} (status: pending)")
+
+# Moderator bypass
+logger.info(f"Moderator bypass activated for deletion submission {submission.id}")
+
+# Deletion applied
+logger.info(f"Park soft-deleted (marked as closed): {park.id}")
+logger.info(f"Company hard-deleted from database: {company.id}")
+```
+
+## Foreign Key Considerations
+
+### Potential Cascading Issues
+- **Parks**: Deleting a park affects related rides
+- **Companies**: Deleting a company affects related parks and rides
+- **RideModels**: Deleting a model affects related rides
+
+### Recommendations
+1. Add deletion validation to check for related entities
+2. Show warnings before allowing deletion
+3. Consider cascade vs. protect on foreign keys
+4. Soft delete preferred to maintain relationships
