Concurrent Rendering Orchestration (React 18)

Summary

Design and validate complex concurrent rendering workflows using useTransition, Suspense, and selective hydration to preserve responsiveness under heavy workloads.

Key Capabilities

• Model UI updates as urgent vs non-urgent and coordinate transitions across nested trees.
• Compose Suspense boundaries to avoid cascading stalls and over-suspension.
• Implement selective hydration strategies that prioritize user-critical regions.

PhD-Level Challenges

• Prove liveness properties for a UI state machine under partial rendering.
• Construct a minimal cut set of Suspense boundaries for optimal TTI.
• Derive empirical thresholds where useTransition improves tail latency.

Acceptance Criteria

• Demonstrate a UI with nested Suspense boundaries and staged reveals.
• Show consistent input responsiveness during large list updates.
• Provide a benchmark report before/after applying transitions.
