See the issue thread where you got the example from or the

I have figured experimentally that I could use (at least in some cases, and after math fonts are initialized which in LaTeX seems to mean one needs to enter math mode at least once before) \font\fixmath=\fontname\textfont\foo mode=base; \textfont\foo=\fixmath for example creating this \fontname: [Vollkorn-Regular]:mode=node;script=latn;language=DFLT;+tlig;+lnum;mode=base; which is then experimentally observed to obey the second mode specifier and thus does display lining figures in math mode.

I only have to figure out the best time to do that in a context (no pun intended) where people may change "\mathversion" (latex thing).

I only need to add the layer to do nothing if "=node" is not found, and

That's easy if one can select the fonts explicitly, but the question
was triggered by the url package which internally switches to math.
Also in the context example there aren't two font definitions:
\starttext
\font\test= {name:TeX-Gyre-Termes:+onum}
\test 0123456789
$\fam0 \textfont0=\test 0123456789$
\stoptext
Nevertheless "\test" seems to use mode=node outside math and
mode=base inside math and I would like to know where the code is
that does it.

Define two fonts: one for use in math mode, another for where you
really, really require node mode.

in your font definition you use a low level xetex like specification so
you bypass the normal feature definition mechanism which means that as
you don't specify a mode, you get base mode which in turn means that the
onum is applied to the font immediately and as you use the same font in
math you get onum there too
{name:TeX-Gyre-Termes:+onum;mode=node}
gives you onum in text as a result of node mode processing but then the
math is normal digits because the font is pass as-is

I assumed the default mode would be like in luaotfload "node". Thanks for correcting me. It is a relieve that I didn't find the font simply because it isn't there ;-).
