Fool shortly facing guaranteed shutdown (7)

Ross

I believe the answer is:

closure

I'm a little stuck... Click here to teach me more about this clue!

'shutdown' is the definition.
(I know that shutdown can be written as closure)

'fool shortly facing guaranteed' is the wordplay.
'fool shortly' becomes 'clo' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'facing' says to put letters next to each other.
'guaranteed' becomes 'sure' (I've seen this in another clue).
'clo'+'sure'='CLOSURE'

Can you help me to learn more?

(Other definitions for closure that I've seen before include "Sealing device" , "End; fastening" , "Ending" , "Stoppage" , "Resolution of emotional upheaval" .)

I've seen this clue in The Guardian.
