Concurrent Debugging Strategies (React 18)

Summary

Develop advanced debugging workflows for concurrent rendering, including reproducibility under non-deterministic scheduling.

Key Capabilities

• Reproduce concurrency bugs using controlled scheduler instrumentation.
• Isolate torn render artifacts with boundary tracing.
• Correlate render phases with state snapshots.

PhD-Level Challenges

• Construct a deterministic replay harness for concurrent updates.
• Formalize minimal counterexamples for concurrency regressions.
• Build tooling to visualize lane interactions in real time.

Acceptance Criteria

• Provide a repro harness with deterministic scheduling.
• Demonstrate isolation of a concurrency bug to a single boundary.
• Document a debugging protocol with evidence.
