Agreed, For this purpose white space is 0x20 or 0x9, space or tab

Separate, but closely related..

Clarification if I may. Do you agree
\s{0-3} arbitrary text termination.

Testing with currentMD,
it would appear that termination can consist of
\n\n   | \ws+\n |\nEOF | \ws+EOF|EOF

where ws is 0x20 |  0x9, I.e. any number of white space characters,
(or the 'empty line').

I intend and believe that my definition matches this.

Curiously, or not (I'm not sure), subsequent 'blank lines' are ignored totally,
yet one in this line termination mode, has effect. This provides a definition
of normalization?
1. A blank line (\ws+\n) terminates a preceding paragraph
2. two or more blank lines are minimized to a single one.

Note that headings are parsed differently from para's? I.e. cannot be
continued on the next line.
#heading
This is a following para

para
this is the same para

So heading termination is different from para termination. worth noting.

Tested with currentMD and file below (assuming no changes with post...
can we have attachments?)

Tests for para start and termination

plain para, terminated by two \n

plain para, only one \n
Is this a new para

 para, 1 leading sp

  para 2 leading sp

   para 3 leading sp

para line ends sans space
continuation line, same para

para line ends one sp
continuation line or not?

para line ends two sp
Is this a cont line?

para line ends three sp
Is this a cont line?

para, \n\s
 continuation line

para, \n\s{1..3}
 continuation line

para, \n\s{1..3}
   continuation line

para
 
para

## Blank lines
Below is 3 * sp \n

Next para
