React

This is a comprehensive React 19 reference with 49 rules across 9 categories, from concurrent rendering and Server Components down to codebase-level hygiene (dead code, duplication, boundary drift). It ships with a category-major review algorithm designed for whole-repo audits, not just single-file questions. Each rule opens with "shapes to recognize" because real violations hide behind syntactic disguises that grep misses. The high-value rules include concrete before/after pairs for pattern detection. Use it when migrating from React 18, auditing a codebase for anti-patterns, or writing new components with modern idioms like ref-as-prop, useActionState, and inline document metadata. Category 9 is where you'll find the remove/dedup/consolidate findings that single-file linters can't see.
