+# Shot Soft Deletion Design
+
+## Overview
+
+This design document outlines the implementation of comprehensive soft deletion for shots in the VFX Project Management System. The solution marks shots and all related data as deleted without removing them from the database, ensuring data preservation for audit and recovery purposes while hiding deleted content from normal operations.
+
+The design follows a single-phase approach: immediate database updates within a transaction to mark all related records as deleted. Physical files are preserved on the file system for potential recovery. This ensures data consistency, maintains audit trails, and provides recovery capabilities.

+
+## Error Handling
+
+### Database Error Handling
+
+1. **Transaction Rollback**: Any database error during soft deletion triggers complete rollback
+2. **Constraint Violations**: Database constraints are handled gracefully with clear error messages
+3. **Concurrent Access**: Database locks prevent concurrent deletion attempts on the same shot
+4. **Connection Failures**: Database connection issues are retried with exponential backoff
+5. **Already Deleted**: Attempts to delete already deleted shots return appropriate error messages
+
+### Data Consistency Error Handling
+
+1. **Missing Related Records**: Missing related records are handled gracefully without failing the operation
+2. **Orphaned Records**: Orphaned records are identified and handled appropriately
+3. **Timestamp Consistency**: All related records receive the same deletion timestamp
+4. **User Reference Integrity**: Deleted_by references are validated before updates
+
+### Recovery Error Handling
+
+1. **Already Active**: Attempts to recover already active shots return appropriate error messages
+2. **Missing Dependencies**: Recovery validates that parent records (episode, project) are still active
+3. **Partial Recovery Failures**: Failed recovery of individual records doesn't prevent recovery of others
+4. **User Permission Validation**: Recovery operations validate user permissions before proceeding
+
+## Testing Strategy
+
+### Unit Testing Approach
+
+Unit tests will focus on individual components and their specific responsibilities:
+
+- **ShotDeletionService**: Test deletion logic, error handling, and transaction management
+- **FileCleanuService**: Test file operations, batch processing, and error recovery
+- **ActivityService**: Test logging functionality and audit trail creation
+- **Frontend Components**: Test UI behavior, confirmation dialogs, and user interactions
+
+### Property-Based Testing Approach
+
+Property-based tests will verify the universal properties across all valid inputs using **Hypothesis** for Python backend testing and **fast-check** for TypeScript frontend testing. Each property-based test will run a minimum of 100 iterations to ensure comprehensive coverage.
+
+**Backend Property Tests** (using Hypothesis):
+- Generate random shots with varying numbers of tasks, submissions, and attachments
+- Test cascading soft deletion properties across different data configurations
+- Verify query exclusion properties with various deleted/active data combinations
+- Test recovery properties with different deletion scenarios
+- Test error handling properties with simulated database failures
+
+**Frontend Property Tests** (using fast-check):
+- Generate random deletion info objects and verify UI calculations
+- Test dialog behavior with various user interaction patterns
+- Verify state management across different component configurations
+- Test recovery UI with various deleted shot configurations
+
+**Property Test Tagging**: Each property-based test will include a comment with the format:
+`# Feature: shot-soft-deletion, Property {number}: {property_text}`
+
+### Integration Testing
+
+Integration tests will verify the complete deletion workflow:
+
+- End-to-end deletion scenarios with real database and file system operations
+- Cross-component communication and data flow validation
+- Error propagation and recovery across system boundaries
+- Performance testing with large datasets
+
+### Test Data Management
+
+- **Database Fixtures**: Standardized test data sets with known relationships
+- **File System Mocking**: Controlled file system environments for testing
+- **Error Simulation**: Configurable failure injection for error path testing
+- **Performance Datasets**: Large-scale test data for performance validation
+
+## Implementation Notes
+
+### Database Considerations
+
+1. **Cascade Configuration**: Leverage existing SQLAlchemy cascade relationships where possible
+2. **Index Optimization**: Ensure proper indexing on foreign key relationships for efficient deletion
+3. **Batch Operations**: Use bulk delete operations for large datasets
+4. **Connection Pooling**: Manage database connections efficiently during long operations
+
+### File System Considerations
+
+1. **Path Validation**: Validate all file paths before attempting deletion
+2. **Atomic Operations**: Use atomic file operations where possible
+3. **Cleanup Ordering**: Delete files before directories to avoid permission issues
+4. **Storage Monitoring**: Monitor disk space during cleanup operations
+
+### Performance Considerations
+
+1. **Lazy Loading**: Avoid loading unnecessary data during deletion operations
+2. **Batch Processing**: Process files and records in configurable batch sizes
+3. **Background Tasks**: Use background task queues for file cleanup operations
+4. **Progress Tracking**: Provide progress feedback for long-running operations
+
+### Security Considerations
+
+1. **Authorization**: Verify user permissions before allowing deletion
+2. **Path Traversal**: Prevent directory traversal attacks in file paths
+3. **Audit Logging**: Log all deletion attempts for security auditing
+4. **Data Sanitization**: Ensure complete data removal for sensitive information
+## Implementation Notes
+
+### Database Considerations
+
+1. **Soft Delete Columns**: Add deleted_at and deleted_by columns to all relevant tables
+2. **Index Optimization**: Create partial indexes on non-deleted records for efficient querying
+3. **Query Modification**: Update all existing queries to exclude deleted records by default
+4. **Migration Strategy**: Implement database migrations to add soft delete columns safely
+
+### Query Pattern Updates
+
+1. **Default Filtering**: All model queries should include `WHERE deleted_at IS NULL` by default
+2. **Admin Queries**: Provide special query methods for administrators to include deleted records
+3. **Recovery Queries**: Implement queries to find and recover deleted records
+4. **Performance Optimization**: Use database indexes to ensure efficient filtering of deleted records
+
+### Performance Considerations
+
+1. **Index Strategy**: Create partial indexes on active records to maintain query performance
+2. **Batch Updates**: Use bulk update operations for marking large numbers of records as deleted
+3. **Query Optimization**: Ensure all queries efficiently exclude deleted records
+4. **Memory Management**: Process large datasets in batches to avoid memory issues
+
+### Security Considerations
+
+1. **Authorization**: Verify user permissions before allowing deletion or recovery
+2. **Audit Logging**: Log all deletion and recovery attempts for security auditing
+3. **Data Access**: Ensure deleted data is only accessible to authorized administrators
+4. **Recovery Permissions**: Implement strict permissions for data recovery operations
+
+### Migration Strategy
+
+1. **Schema Updates**: Add soft delete columns to existing tables without downtime
+2. **Data Integrity**: Ensure existing data remains unaffected during migration
+3. **Query Updates**: Gradually update application queries to use soft delete filtering
+4. **Rollback Plan**: Provide rollback procedures in case of migration issues

+# Shot Soft Deletion Requirements
+
+## Introduction
+
+This specification defines the requirements for implementing comprehensive soft deletion when a shot is "deleted" from the VFX Project Management System. Instead of permanently removing data, the system will mark shots and all related data as deleted while preserving the records in the database for potential recovery and audit purposes.
+
+## Glossary
+
+- **Shot**: A sequence of frames in an episode that represents a specific scene or action
+- **Task**: A work item assigned to a shot (e.g., animation, lighting, compositing)
+- **Submission**: A file uploaded by an artist as work progress for a task
+- **Attachment**: Reference files, documentation, or other files attached to a task
+- **Production Note**: Comments, feedback, or discussion items related to a task
+- **Review**: Approval/feedback records for submissions
+- **Activity**: System-generated log entries tracking changes and actions
+- **Soft Deletion**: Marking records as deleted without removing them from the database
+- **Cascading Soft Deletion**: Automatically marking all related records as deleted when a parent record is soft deleted
+- **Deleted Flag**: A database field indicating whether a record is considered deleted
+
