title: "Refactor monolithic process_data() into three focused functions"
description: |
  processor.py contains a single 60+ line process_data() function that validates,
  transforms, and formats data all in one place. Extract three top-level functions:
  validate_data(data), transform_data(data), format_output(data).
  process_data() must delegate to all three and continue to work correctly.
