Clean/Repair History Icons?

Hi Team,

In Console

  In "Security and Patch Information"

    In "Clean/Repair History"

      Under "Date/Time"

I have some icons that I don't fully understand ?

   .see the image

Looking around I can see different bit of information regarding Icon used in the 32bit Console, but is there a definitive list of Icons used ?

However, I'd settle for understanding these icons in "Clean/Repair"

.....Dave
