Concurrent-Safe State Machines (React 18)

Summary

Design deterministic state machines that remain correct under concurrent rendering and re-entrancy.

Key Capabilities

• Apply idempotent reducers and effect cleanup patterns.
• Model state transitions as pure functions with replay tolerance.
• Prevent torn reads during interleaved renders.

PhD-Level Challenges

• Prove invariants under double-invocation in StrictMode.
• Provide a correctness argument for side-effect isolation.
• Stress-test state transitions under randomized scheduling.
