# Cross-Boundary Consistency (React 18)

## Summary

Guarantee data and UI consistency across multiple `Suspense` and error boundaries.

## Key Capabilities

- Design cross-boundary synchronization protocols.
- Prevent inconsistent partial renders during rapid updates.
- Implement conflict resolution for overlapping data sources.

## PhD-Level Challenges

- Prove invariants across boundary partitions.
- Analyze consistency under partial hydration and retries.
- Derive conflict-free merge strategies for concurrent data.

## Acceptance Criteria

- Demonstrate consistent UI state across boundaries under load.
- Provide invariants and a proof sketch.
- Document recovery behavior for conflicting updates.
