Resource Cache Invalidation (React 18)

Summary

Implement advanced caching with precise invalidation for highly dynamic data domains.

Key Capabilities

• Design multi-tier caches (in-memory + persisted) with TTL policies.
• Implement versioned cache keys to prevent stale hydration.
• Use dependency-based invalidation with minimal recomputation.

PhD-Level Challenges

• Formally reason about cache staleness windows and correctness.
• Analyze invalidation cascades in high-churn data graphs.
• Derive optimal TTL under changing network conditions.

Acceptance Criteria

• Provide cache hit-rate analysis before/after improvements.
• Demonstrate deterministic cache invalidation behavior.
• Document consistency guarantees and failure modes.
