Follow-up: The 66 complaints come from \startsection .. \stopsection pairs (and
\startsubsection .. \stopsubsection).
Adding just one of them increases the number of complaints by two.
Instead of your
\setupheads
[section,subsection]
[color=darkred]
\setuphead
[section]
[style=\bfb]
\setuphead
[subsection]
[style=\bfa]
I use
\setuphead[subsection][number=yes,
page=yes,
before={\noindentation\hairline\blank},
after={\nowhitespace\hairline\blank[line]\indentation}]
\setuphead[section][number=yes,
page=yes,
before={\noindentation\hairline\blank},
after={\nowhitespace\hairline\blank[line]\indentation}]
which is causing trouble somehow. No big deal.
