This is not about semantics. The point position when there is hidden
text is generally ambiguous. Emacs chooses to put point before or after
invisible text depending on the "direction" of the last command. See
22.6 Adjusting Point After Commands section of Elisp manual, if you want
to know the details. The scenario when invisible text is right at bol is
the most tricky.

Unescaped brackets are not allowed in the link path.
See 4.1 Link Format section of the manual

      [[LINK][DESCRIPTION]]
     
     or alternatively
     
          [[LINK]]
     
        Some ‘\’, ‘[’ and ‘]’ characters in the LINK part need to be
     “escaped”, i.e., preceded by another ‘\’ character.  More specifically,
     the following characters, and only them, must be escaped:
     
       1. all ‘[’ and ‘]’ characters,
       2. every ‘\’ character preceding either ‘]’ or ‘[’,
       3. every ‘\’ character at the end of the link.
