Ensure that method, variable, and class names accurately reflect their actual behavior, purpose, or content. Names should semantically match what they represent to prevent confusion and bugs.

Key principles:

• Method names should match their actual behavior: detachX() should perform get + cancel, not just cancel
• Variable names should reflect their content: patch_block_indices not patch_col_indices when indexing blocks
• Class names should accurately describe their function: Serialization not Compression when the class handles serialization
• Method names should be descriptive of their purpose: shouldSearchForPartsOnDisk() not lookOnDisk()
• Use consistent, accurate terminology throughout: disk not drive when referring to storage disks

Example of problematic vs. corrected naming:

// Problematic - method name doesn't match behavior
void detachParallelReadingExtension(); // actually just clears/cancels

// Corrected - name matches actual behavior  
void clearParallelReadingExtension(); // or implement proper detach semantics

// Problematic - variable name doesn't match content
PaddedPODArray<UInt64> patch_col_indices; // actually indexes blocks

// Corrected - name matches content
PaddedPODArray<UInt64> patch_block_indices;

This prevents misunderstandings about code behavior and makes the codebase more maintainable by ensuring names serve as accurate documentation of functionality.
