Observability for React Concurrency (React 18)

Summary

Implement advanced observability to capture concurrent rendering behavior and scheduling anomalies.

Key Capabilities

• Trace concurrent render events with lane metadata.
• Correlate UI traces with backend spans.
• Detect scheduling anomalies and alert on regressions.

PhD-Level Challenges

• Formalize anomaly detection for concurrent schedules.
• Optimize sampling without losing tail-event fidelity.
• Validate observability accuracy under load.

Acceptance Criteria

• Provide a trace schema and sample dashboards.
• Demonstrate detection of a concurrency anomaly.
• Document sampling strategy and trade-offs.
