bold_heading_pattern will match lines like ** ** (only whitespace inside the bold markers). Because the capture group is stripped before storing, this can create nodes with an empty node_title, which later yields empty titles in the tree. Consider tightening the regex to require non-whitespace content inside **...**, or add a guard to skip appending when the stripped title is empty.
