Event Sourcing for UI State (React 18)

Summary

Use event sourcing to build auditable, replayable UI state systems compatible with concurrent rendering.

Key Capabilities

• Model UI state transitions as append-only event logs.
• Support replay and time-travel debugging at scale.
• Maintain consistency under concurrent updates.

PhD-Level Challenges

• Prove convergence of event streams under concurrency.
• Design compaction strategies for long-lived logs.
• Analyze storage/performance trade-offs for event sourcing.

Acceptance Criteria

• Provide a replayable UI event log implementation.
• Demonstrate time-travel debugging with deterministic results.
• Document compaction and retention policies.
