-# Vue Node Resize Tracking Optimization
-
-## Summary
-
-Implemented centralized resize tracking system with O(1) element registration, single ResizeObserver traversal, and extensible ECS architecture to optimize Vue node bounds synchronization.
-
-## Changes
-
-- **What**: Centralized resize registry with single ResizeObserver, optimized math functions for bounds computation, extensible tracking system, DDD-compliant file organization
-- **Breaking**: Moved composable from `src/composables/` to `src/renderer/extensions/vueNodes/composables/` (DDD architecture)
-- **Dependencies**: None
-
-## Review Focus
-
-### Performance Optimizations
-- **Single ResizeObserver**: Replaced per-component observers with centralized registry to minimize browser reflow
-- **O(1) Element Access**: Map-based tracking configs eliminate linear searches across element types
-- **Single Traversal**: Batch processing groups updates by type in one ResizeObserver callback
-- **Optimized Math**: Union bounds computation uses incremental min/max instead of array operations
-
-### Architecture Decisions
-- **ECS Pattern**: Element-Component-System design allows tracking different element types (nodes, widgets, slots) with shared infrastructure
-- **Extensible Registry**: `trackingConfigs` Map enables adding new element types without core logic changes
-- **Data Attribute Strategy**: Uses configurable data attributes (e.g., `data-node-id`) for O(1) element identification vs DOM traversal
-
-### Technical Implementation
-- **Yjs Batch Optimization**: Removed race condition check in `batchUpdateNodeBounds` that could drop updates during concurrent transactions
-- **Null Safety**: Replaced never-null assertions with proper error handling and null checks
-- **Vue Lifecycle Integration**: Automatic cleanup on component unmount prevents memory leaks
-- **Type Safety**: Full TypeScript coverage with proper bounds interfaces
-
-### Testing Strategy
-- **Component-focused**: Uses Vue Test Utils for realistic DOM integration vs complex unit test mocking
-- **Utility Extraction**: Centralized test setup eliminates repetitive mock configuration
-- **Injection Mocking**: Proper Vue dependency injection setup for component isolation
-
-### Mathematical Optimizations
-- **Bounds Union**: `computeUnionBounds` uses streaming min/max calculation (O(n)) instead of coordinate array operations (O(n log n))
-- **Transform Calculations**: Leverages ResizeObserver's native `contentBoxSize` API for accurate dimensions without layout thrashing
