Custom Renderer Implementation (React 18)

Summary

Architect bespoke React renderers for non-DOM environments using the react-reconciler package.

Key Capabilities

• Implement a full HostConfig interface for a custom target.
• Map fiber mutations to imperative host API calls.
• Manage persistent vs. transient host instance updates.

PhD-Level Challenges

• Design a scheduling-aware host config for Frame-limited targets.
• Prove correctness of the mutation queue execution order.
• Implement concurrent mode support for a custom target.

Acceptance Criteria

• Deploy a working custom renderer (e.g., to Canvas or Terminal).
• Demonstrate correct update propogation.
• Pass the standard React conformance test suite for renderers.
