These templates declared pdfstandard=ua-2 and loaded tagpdf with
\tagpdfsetup{activate-all}. That combination sets /Marked true and
writes the PDF/UA-2 claim into the metadata, but activate-all is
tagpdf's low-level switch and does not turn on the kernel code that
tags document structure. The result was a file announcing itself as
accessible while carrying nothing for assistive software to read: the
memo's structure tree held one /Document and two /Link nodes, and the
letter's held /Document alone.
tagging=on loads that kernel code. The memo now tags three headings, a
subsection, its paragraphs and its bibliography list; the letter tags
all ten body paragraphs. The manual tagpdf lines are no longer needed
since the kernel loads it.
This requires TeX Live 2025 or later; on TeX Live 2024 the key is
unknown and the build stops.
