Use names that clearly reflect the thing being identified, and ensure renamed identifiers don’t accidentally couple to old data or misleading conventions.

• When an identifier backs persisted/external state (e.g., localStorage keys), rename the storage key as well to prevent reusing stale values after refactors.

  // Before: reads old stored values
  const [sortDesc, setSortDesc] = useLocalStorage('reactQueryDevtoolsSortDesc', '')
  
  // After: new state name, use a new storage key
  const [baseSort, setBaseSort] = useLocalStorage('reactQueryDevtoolsBaseSort', '')
  

• Name test files/identifiers for the specific scenario being tested; avoid redundant labels when the suffix/extension already implies the category.

  # Prefer a scenario/feature name
  mutations.test-d.tsx
  

Applying this keeps naming semantically aligned with behavior and prevents accidental cross-contamination from previously persisted names.
