Precision Re-render Control (React 18)

Summary

Minimize unnecessary re-renders through precise state partitioning and selector-driven updates.

Key Capabilities

• Implement selector-based memoization for fine-grained updates.
• Partition global state to isolate hot paths.
• Detect referential instability and eliminate it.

PhD-Level Challenges

• Construct a formal model of re-render propagation.
• Prove minimality of renders under defined constraints.
• Evaluate selector stability with adversarial updates.

Acceptance Criteria

• Provide render-count baselines and improvements.
• Demonstrate stable selectors with no thrashing.
• Document state partition strategy.
