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.
