| 23 | +## Goals for This Week |
| 24 | + |
| 25 | +- Design and implement a comprehensive brick tree model for managing hierarchical connections |
| 26 | +- Implement connection validation based on brick types and notch availability |
| 27 | +- Create robust tree management with proper merging and splitting behavior |
| 28 | +- Develop comprehensive test coverage for all tree operations |
| 29 | + |
| 30 | +--- |
| 31 | + |
| 32 | +## This Week's Achievements |
| 33 | + |
| 34 | +### 1. **Comprehensive Brick Tree Model Implementation** |
| 35 | + |
| 36 | +Developed a `BrickTreeManager` class that handles: |
| 37 | +- **Tree Structure Management**: Each tree has a unique ID that changes when connections/disconnections occur |
| 38 | +- **Hierarchical Connections**: Parent-child relationships where disconnecting a parent keeps children connected |
| 39 | +- **Connection Validation**: Ensures bricks can only connect if their notches are compatible and available |
| 40 | + |
| 41 | +### 2. **Advanced Connection System** |
| 42 | + |
| 43 | +Implemented a dual connection approach: |
| 44 | +- **Top-Bottom Connections**: Hierarchical parent-child relationships |
| 45 | +- **Left-Right Notch Connections**: Graph-like where bricks connect only if their right and left notches are free |
| 46 | +- **Nested Notch Support**: Support for complex nested brick structures |
| 47 | +- **Connection State Tracking**: Real-time tracking of which notches are occupied or available |
| 48 | + |
| 49 | +### 3. **Tree Management** |
| 50 | + |
| 51 | +Created tree operations: |
| 52 | +- **Tree Merging**: When bricks connect, their respective trees merge into a single tree |
| 53 | +- **Tree Splitting**: When bricks disconnect, new trees are formed preserving child relationships |
| 54 | +- **Hierarchical Disconnection**: Disconnecting a parent preserves child connections and forms new trees |
| 55 | +- **UUID Management**: Each brick has a unique UUID, and trees have dynamic IDs that change with connections |
| 56 | + |
| 57 | +### 4. **Comprehensive Test Suite** |
| 58 | + |
| 59 | +Developed extensive test coverage including: |
| 60 | +- **Connection Tests**: Validating proper tree merging when bricks connect |
| 61 | +- **Disconnection Tests**: Ensuring correct tree splitting behavior |
| 62 | +- **Hierarchical Tests**: Testing parent-child relationship preservation |
| 63 | +- **Notch Validation Tests**: Verifying connection rules based on notch availability |
| 64 | +- **Edge Case Tests**: Handling complex scenarios with multiple connections |
| 65 | + |
| 66 | +### 5. **Type Safety and Validation** |
| 67 | + |
| 68 | +Enhanced the type system with: |
| 69 | +- **Brick Type Definitions**: Clear interfaces for Simple, Expression, and Compound bricks |
| 70 | +- **Connection Validation**: Type-safe connection checking based on brick types |
| 71 | +- **Notch Compatibility**: Validation ensuring only compatible notches can connect |
| 72 | +- **Error Handling**: Comprehensive error handling for invalid operations |
| 73 | + |
| 74 | +--- |
| 75 | + |
| 76 | +## Technical Implementation Details |
| 77 | + |
| 78 | +### Brick Tree Structure |
| 79 | +```typescript |
| 80 | +interface BrickTree { |
| 81 | + id: string; |
| 82 | + bricks: Map<string, Brick>; |
| 83 | + connections: Map<string, Connection>; |
| 84 | + rootBricks: Set<string>; |
| 85 | +} |
| 86 | +``` |
| 87 | + |
| 88 | +### Connection Types |
| 89 | +- **Hierarchical Connections**: Top-bottom parent-child relationships |
| 90 | +- **Notch Connections**: Left-right graph-like connections |
| 91 | +- **Nested Connections**: Complex nested brick structures |
| 92 | + |
| 93 | +### Key Features |
| 94 | +- **Automatic Tree ID Generation**: Trees get new IDs when connections change |
| 95 | +- **Connection Validation**: Ensures only valid connections are allowed |
| 96 | +- **Hierarchical Preservation**: Child relationships are maintained during disconnections |
| 97 | + |
| 98 | +--- |
| 99 | + |
| 100 | +## Challenges & How I Overcame Them |
| 101 | + |
| 102 | +### Challenge 1: Hierarchical vs Graph-like Connections |
| 103 | +**Problem**: Balancing hierarchical parent-child relationships with graph-like notch connections was complex. |
| 104 | +**Solution**: Implemented a dual connection system where hierarchical connections manage the tree structure, while notch connections provide the visual puzzle-like behavior. |
| 105 | + |
| 106 | +### Challenge 2: Tree Splitting Logic |
| 107 | +**Problem**: Ensuring that disconnecting a parent brick correctly preserves child relationships and forms new trees. |
| 108 | +**Solution**: Developed a algorithm that traverses the tree structure, identifies connected components, and creates new trees while maintaining all valid connections. |
| 109 | + |
| 110 | +### Challenge 3: Connection Validation |
| 111 | +**Problem**: Ensuring that bricks can only connect when their notches are compatible and available. |
| 112 | +**Solution**: Created a comprehensive validation system that checks notch types, availability, and compatibility before allowing connections. |
| 113 | + |
| 114 | +### Challenge 4: Test Coverage |
| 115 | +**Problem**: Creating comprehensive tests for complex tree operations and edge cases. |
| 116 | +**Solution**: Developed a systematic testing approach covering all major operations, edge cases, and error conditions with clear test descriptions. |
| 117 | + |

| 119 | + |
| 120 | +## Key Learnings |
| 121 | + |
| 122 | +- **Tree Data Structures**: Deep understanding of tree management, merging, and splitting operations |
| 123 | +- **Graph Theory**: Applied graph concepts for notch-based connections |
| 124 | +- **Type Safety**: Enhanced TypeScript skills with complex type definitions and validation |
| 125 | +- **Testing Strategies**: Learned systematic approaches to testing complex data structures |
| 126 | +- **Algorithm Design**: Developed algorithms for tree traversal and component identification |
| 127 | + |
| 128 | +--- |
| 129 | + |
| 130 | +## Code Quality Improvements |
| 131 | + |
| 132 | +- **Comprehensive Documentation**: Added detailed JSDoc comments for all public methods |
| 133 | +- **Type Safety**: Enhanced TypeScript interfaces and type checking |
| 134 | +- **Test Coverage**: Achieved high test coverage with edge case testing |
| 135 | + |
| 136 | +--- |
| 137 | + |
| 138 | +## Next Week's Roadmap |
| 139 | + |
| 140 | +- **Visual Tree Rendering**: Implement visual representation of the brick tree structure |

| 142 | +- **Performance Optimization**: Optimize tree operations for large brick structures |
| 143 | +- **Integration Testing**: Test the tree model with the existing brick rendering system |
