From CommonMark Spec 0.31.2 Section 6.3 Links:
An inline link consists of a link text followed immediately by a left parenthesis
(, an optional link destination, an optional link title, and a right parenthesis). These four components may be separated by spaces, tabs, and up to one line ending.
(Bold added. Links removed due to forum new user limitations.)
In my reading it is unclear what the phrase “these four components” refers to. There are five components mentioned in the preceding sentence (inline link, left paren, link destination, link title, right paren).
Experimenting with the Java implementation, it seems clear you are referring to the last four components in that sentence. (The link text really does need to be followed “immediately” by the left paren, but there can be a newline/space after the paren, before the closing paren, a newline between the link and title, etc.)
I would suggest rephrasing to make clearer what components you refer to, such as:
An inline link consists of a link text followed immediately by a left parenthesis
(, an optional link destination, an optional link title, and a right parenthesis). The four components after the link text may be separated by spaces, tabs, and up to one line ending.
(New phrasing in bold for visibility; I do not propose it be bold in the final text.)
