Looks like #353 broke the PDF build. Relevant error message:

! Package amsmath Error: Extra & on this line.

See the amsmath package documentation for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.4712 \end{alignat*}

Based on this, my guess is that the issue is in the <md> beginning at line 176 of 02-EV/07.ptx

<md alignat-columns='5' alignment="alignat">
<mrow>
2x_1&amp;\,+\,&amp;4x_2&amp;\,+\,&amp;2x_3 &amp;\,-\,&amp;3 x_4 &amp;\,+\,&amp;31x_5&amp;\,+\,&amp;2x_6&amp;\,-\,&amp;16x_7&amp;=&amp; 0

</md>

Eyeballing it, looks like the alignat-columns is too few?

I believe this was taken care of in #494
