Fiber Scheduling Theory (React 18)

Summary

Apply deep knowledge of Fiber scheduling to reason about rendering priorities, preemption, and starvation avoidance.

Key Capabilities

• Interpret scheduler lanes and priority escalation behavior.

• Model preemption effects on UI atomicity guarantees.

• Diagnose starvation risks and mitigate via boundary design.

PhD-Level Challenges

• Construct a formal scheduling model for multi-lane updates.

• Derive starvation bounds under adversarial update patterns.

• Evaluate performance regressions using synthetic lane stress tests.

Acceptance Criteria

• Present a lane diagram for a complex interaction scenario.

• Validate that high-priority input stays responsive under load.

• Explain trade-offs in at least two real scheduling decisions.
