full scale

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

'unrestricted' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?

'satisfied climb' is the wordplay.
'satisfied' becomes 'full' (e.g. after eating).
'climb' becomes 'scale' (scaling is a kind of climbing).
'full'+'scale'='FULL-SCALE'

Can you help me to learn more?

(Other definitions for full scale that I've seen before include "one to one" , "comprehensive" .)
