"Inviolable" is just an internal Custom tag.  From cus-start.el:

(const :tag "Inviolable"
       :doc "Prevent point from ever entering prompt"
       :format "%t%n%h"
       :inline t
       (point-entered minibuffer-avoid-prompt))

    - Is "intangible" not the same property as what Customize refers to as
   "inviolable"? More precisely, isn't the "intangible" property what makes the
   minibuffer-prompt area "inviolable"?

No, it is the point-entered property, as you can see from the above.
If it were the intangible property, you would be able to move to the
beginning of the prompt, you would just not be able to move _inside_
the prompt.  In other words, C-b would not stop just after the
prompt.  Instead, it would move from just after the prompt to the
beginning of the minibuffer with one single C-b.

    - If so,

It is not so, so I guess that makes the remainder of the message irrelevant.

Sincerely,
