  execution is a fundamental directory that includes 3 subdirectories: history, impl and steps.
  In the root directory, 'history' carries 2 directories: changes, impl.
  Within directory hierarchy 'history / changes', 'changes' is blank.
  Within directory hierarchy 'history / impl', The 'impl' folder awaits content.
  Back to the top level.
  At the top level, Inside 'impl', you'll find it stands empty.
  In the root directory, 'steps' is barren.

   |   `--plugins
   |       `--catalog
   |           `--internal
   `--catalog
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
