+# Version Control System API Documentation
+
+## Overview
+The version control system provides a comprehensive API for managing content versioning, branching, and merging across different models in the system.
+
+## Core Models
+
+### VersionBranch
+Represents a branch in the version control system.
+
+```python
+class VersionBranch:
+ name: str # Branch name (unique)
+ metadata: JSONField # Branch metadata
+ is_active: bool # Branch status
+ created_at: datetime
+ updated_at: datetime
+```
+
+### ChangeSet
+Represents a set of changes to a versioned object.
+
+```python
+class ChangeSet:
+ branch: ForeignKey # Reference to VersionBranch
+ content_type: ForeignKey # ContentType of the changed object
+ object_id: int # ID of the changed object
+ data: JSONField # Change data
+ status: str # Status (pending, applied, conflict)
+ created_at: datetime
+ applied_at: datetime
+```

+
+## Model Integration
+
+### Adding Version Control to Models
+
+To make a model version-controlled, inherit from `HistoricalModel`:
+
+```python
+from history_tracking.models import HistoricalModel
+
+class YourModel(HistoricalModel):
+ name = models.CharField(max_length=255)
+
+ def save(self, *args, **kwargs):
+ # Get the branch from context
+ current_branch = get_current_branch()
+
+ if current_branch:
+ # Save in branch context
+ super().save(*args, **kwargs)
+ else:
+ # Save in main branch
+ with ChangesetContextManager(branch=main_branch):
+ super().save(*args, **kwargs)
+```
+
+### Version Control Methods
+
+Each versioned model has access to these methods:
+
+#### get_version_info()
+Returns version control information for the object:
+```python
+info = model.get_version_info()
+# Returns:
+{
+ 'latest_changes': [ChangeSet],
+ 'active_branches': [VersionBranch],
+ 'current_branch': VersionBranch,
+ 'total_changes': int
+}
+```
+
+#### get_changes()
+Returns all changes for the object:
+```python
+changes = model.get_changes()
+# Returns QuerySet of ChangeSet objects
+```
+
+## JavaScript Integration
+
+### Version Control UI
+
+Initialize version control UI:
+```javascript
+import { initVersionControl } from 'version-control.js';
+
+initVersionControl({
+ container: '#version-control-panel',
+ onChange: (branch) => {
+ // Handle branch change
+ }
+});
+```
+
+### Branch Operations
+
+Switch branches:
+```javascript
+import { switchBranch } from 'version-control.js';
+
+switchBranch(branchId).then(response => {
+ if (response.status === 'success') {
+ // Handle successful branch switch
+ }
+});
+```
+
+### Merge Operations
+
+Handle merge conflicts:
+```javascript
+import { handleMergeConflicts } from 'version-control.js';
+
+handleMergeConflicts(conflicts).then(resolutions => {
+ // Handle conflict resolutions
+});
+```
+
+## Error Handling
+
+The API uses standard HTTP status codes:
+
+- 200: Success
+- 400: Bad Request
+- 401: Unauthorized
+- 403: Forbidden
+- 404: Not Found
+- 409: Conflict (merge conflicts)
+- 500: Internal Server Error
+
+Error responses include detailed information:
+```json
+{
+ "status": "error",
+ "message": "Detailed error message",
+ "code": "ERROR_CODE",
+ "details": {
+ // Additional error details
+ }
+}
+```
+
+## Rate Limiting
+
+API endpoints are rate-limited:
+- Authenticated users: 100 requests per minute
+- Anonymous users: 20 requests per minute
+
+Rate limit headers are included in responses:
+```http
+X-RateLimit-Limit: 100
+X-RateLimit-Remaining: 95
+X-RateLimit-Reset: 1623456789
+```
+
+## Monitoring
+
+Monitor version control operations through the monitoring dashboard:
+```http
+GET /version-control/monitoring/
+```
+
+The dashboard provides real-time metrics for:
+- Branch operations
+- Merge success rates
+- Change tracking overhead
+- Error rates
+- System health

+# Version Control User Guide
+
+## Introduction
+The version control system allows you to track changes, create branches, and merge content updates across ThrillWiki. This guide explains how to use the version control features effectively.
+
+## Basic Concepts
+
+### Branches
+A branch is a separate line of development that allows you to make changes without affecting the main content. Think of it like a draft version of your content.
+
+- **Main Branch**: The default branch containing the live, published content
+- **Feature Branches**: Temporary branches for developing new content or making significant changes
+- **Active Branch**: The branch you're currently working on
+
+### Changes
+Changes represent modifications to content:
+- Adding new information
+- Updating existing content
+- Removing outdated content
+
+### Merging
+Merging combines changes from one branch into another, typically from a feature branch back into the main branch.
+
+## Using Version Control
+
+### 1. Version Control Panel
+The version control panel appears at the top of editable pages and shows:
+- Current branch
+- Branch selector
+- Action buttons (Create Branch, Merge, etc.)
+
+
+
+### 2. Creating a Branch
+1. Click "Create Branch" in the version control panel
+2. Enter a branch name (e.g., "update-park-details")
+3. Add an optional description
+4. Click "Create"
+
+Branch naming conventions:
+- Use lowercase letters
+- Separate words with hyphens
+- Be descriptive (e.g., "add-new-rides", "update-park-history")
+
+### 3. Switching Branches
+1. Open the branch selector in the version control panel
+2. Select the desired branch
+3. Click "Switch Branch"
+
+Note: You'll see a warning if you have unsaved changes.
+
+### 4. Making Changes
+1. Ensure you're on the correct branch
+2. Edit content normally
+3. Save changes
+4. Changes are tracked automatically
+
+The version control panel shows:
+- Number of changes
+- Last update time
+- Change status
+
+### 5. Viewing History
+1. Click "History" in the version control panel
+2. See a list of changes with:
+ - Timestamp
+ - Author
+ - Description
+ - Branch
+3. Click any change to see details
+
+### 6. Merging Changes
+1. Switch to the target branch (usually main)
+2. Click "Merge" in the version control panel
+3. Select the source branch
+4. Review changes
+5. Click "Merge Changes"
+
+### 7. Handling Conflicts
+If conflicts occur during merging:
+1. The conflict resolution dialog appears
+2. Review conflicting changes
+3. Choose which version to keep or combine them
+4. Click "Resolve Conflicts"
+5. Complete the merge
+
+## Best Practices
+
+### When to Create a Branch
+Create a new branch when:
+- Making substantial content updates
+- Adding new sections
+- Reorganizing information
+- Testing new features
+
+### Branch Management
+- Keep branches focused on specific tasks
+- Delete branches after merging
+- Regular merge changes from main to stay current
+- Use descriptive branch names
+
+### Change Management
+- Make atomic, related changes
+- Write clear change descriptions
+- Review changes before merging
+- Test content in preview mode
+
+### Collaboration
+- Communicate branch purpose to team members
+- Coordinate on shared branches
+- Review changes before merging
+- Resolve conflicts together when needed
+
+## Common Tasks
+
+### Updating a Park Page
+1. Create a branch (e.g., "update-park-info")
+2. Make changes to park information
+3. Preview changes
+4. Merge back to main when ready
+
+### Adding New Rides
+1. Create a branch (e.g., "add-new-rides-2025")
+2. Add ride information
+3. Add photos and details
+4. Review and merge
+
+### Content Reorganization
+1. Create a branch (e.g., "reorganize-sections")
+2. Rearrange content
+3. Update navigation
+4. Test thoroughly
+5. Merge changes
+
+## Troubleshooting
+
+### Common Issues
+
+#### Unable to Create Branch
+- Check permissions
+- Verify branch name is valid
+- Ensure no conflicts with existing branches
+
+#### Merge Conflicts
+1. Don't panic! Conflicts are normal
+2. Review both versions carefully
+3. Choose the best content
+4. Test after resolving
+
+#### Lost Changes
+1. Check branch history
+2. Review recent changes
+3. Contact administrator if needed
+
+### Getting Help
+- Click the "Help" button in the version control panel
+- Contact administrators for complex issues
+- Check documentation for guidance
+
+## Version Control Status Icons
+
+| Icon | Meaning |
+|------|---------|
+| 🟢 | Current branch |
+| 🔄 | Pending changes |
+| ⚠️ | Merge conflicts |
+| ✅ | Successfully merged |
+| 🔒 | Protected branch |

+# Change Approval Workflow Implementation Plan
+
+ ## Core Requirements
+ 1. Configurable approval stages
+ 2. Role-based reviewer assignments
+ 3. Parallel vs sequential approvals
+ 4. Audit trail of decisions
+ 5. Integration with existing locks/comments
+
+ ## Technical Integration
+ - **State Machine**
+ Extend StateMachine interface:
+ ```typescript
+ interface ApprovalStateMachine extends StateMachine {
+ currentStage: ApprovalStage;
+ requiredApprovers: UserRef[];
+ overridePolicy: 'majority' | 'unanimous';
+ }
+ ```
+
+ - **Model Extensions**
+ Enhance ChangeSet (line 7):
+ ```python
+ class ChangeSet(models.Model):
+ approval_state = models.JSONField(default=list) # [{stage: 1, approvers: [...]}]
+ approval_history = models.JSONField(default=list)
+ ```
+
+ - **API Endpoints**
+ Add to VersionControlViewSet (line 128):
+ ```python
+ @action(detail=True, methods=['post'])
+ def submit_for_approval(self, request, pk=None):
+ """Transition change set to approval state"""
+ ```
+
+ ## Security Considerations
+ - Approval chain validation
+ - Non-repudiation requirements
+ - Conflict resolution protocols
+ - Approval delegation safeguards
+
+ ## Phase Plan
+ 1. **Week 1**: State machine implementation
+ 2. **Week 2**: Approval UI components
+ 3. **Week 3**: Integration testing
+ 4. **Week 4**: Deployment safeguards

+# Branch Locking System Implementation Plan
+
+ ## Core Requirements
+ 1. Role-based locking permissions
+ 2. Lock state indicators in UI
+ 3. Lock override protocols
+ 4. Audit logging for lock events
+ 5. Maximum lock duration: 48hrs
+
+ ## Technical Integration
+ - **Model Extensions**
+ Enhance `VersionBranch` (line 14):
+ ```python
+ class VersionBranch(models.Model):
+ lock_status = models.JSONField(default=dict) # {user: ID, expires: datetime}
+ lock_history = models.JSONField(default=list)
+ ```
+
+ - **Manager Methods**
+ Add to `BranchManager` (line 141):
+ ```python
+ def acquire_lock(self, branch, user, duration=48):
+ """Implements lock with timeout"""
+
+ def release_lock(self, branch, force=False):
+ """Handles lock release with permission checks"""
+ ```
+
+ - **UI Components**
+ Update `VersionControlUI` interface (line 58):
+ ```typescript
+ lockState: {
+ isLocked: boolean;
+ lockedBy: UserRef;
+ expiresAt: Date;
+ canOverride: boolean;
+ };
+ ```
+
+ ## Security Considerations
+ - Permission escalation prevention
+ - Lock expiration enforcement
+ - Audit log integrity checks
+ - Session validation for lock holders
+
+ ## Phase Plan
+ 1. **Week 1**: Locking backend implementation
+ 2. **Week 2**: Permission system integration
+ 3. **Week 3**: UI indicators & controls
+ 4. **Week 4**: Audit system & testing

+# Version Control Security Audit Checklist
+
+ ## Core Security Domains
+ 1. **Authentication**
+ - [ ] MFA required for lock overrides (Branch Locking.md Line 58)
+ - [ ] Session invalidation on permission changes
+
+ 2. **Authorization**
+ - [ ] Role hierarchy enforcement (Approval Workflow.md Line 22)
+ - [ ] Context-sensitive permission checks
+
+ 3. **Data Protection**
+ - [ ] Encryption of comparison metadata (Version Comparison.md Line 6)
+ - [ ] Audit log integrity verification
+
+ 4. **Workflow Security**
+ - [ ] State machine tamper detection (Approval Workflow.md Line 45)
+ - [ ] Comment edit history immutability
+
+ ## Threat Mitigation Table
+ | Threat Type | Affected Feature | Mitigation Strategy |
+ |-------------|------------------|---------------------|
+ | Race Conditions | Branch Locking | Optimistic locking with version stamps |
+ | XSS | Change Comments | DOMPurify integration (Line 89) |
+ | Data Leakage | Version Comparison | Strict field-level encryption |
+ | Repudiation | Approval Workflow | Blockchain-style audit trail |
+
+ ## Testing Procedures
+ 1. **Penetration Tests**
+ - Lock bypass attempts via API fuzzing
+ - Approval state injection attacks
+
+ 2. **Static Analysis**
+ - OWASP ZAP scan configuration
+ - SonarQube security rule activation
+
+ 3. **Runtime Monitoring**
+ - Unauthorized diff access alerts
+ - Abnormal approval pattern detection
+
+ ## Phase Integration
+ | Development Phase | Security Focus |
+ |--------------------|----------------|
+ | Locking Implementation | Permission model validation |
+ | Workflow Development | State transition auditing |
+ | Comment System | Content sanitization checks |
+ | Comparison Tool | Data anonymization tests |
+
+ ## Severity Levels
+ - **Critical**: Direct system access vulnerabilities
+ - **High**: Data integrity risks
+ - **Medium**: UX security weaknesses
+ - **Low**: Informational exposure
