# Memory Leak Analysis in SPAs

## Summary
Detect, isolate, and fix memory leaks in long-running React Single Page Applications.

## Key Capabilities
- Profile heap snapshots to find detached DOM trees.
- Identify closure retention cycles in hooks and listeners.
- Verify cleanup execution in `useEffect` and unmount life-cycles.

## PhD-Level Challenges
- Automate regression testing for memory consumption.
- Analyze leaks caused by hydration of large data structures.
- Trace leaks across React Router navigation boundaries.

## Acceptance Criteria
- Provide heap comparison reports before/after fixes.
- Demonstrate stable memory usage over extended sessions.
- Document memory profiling methodology.
