• Renderer=Basic sometimes munches on characters. latex3/luaotfload#241
• https://tex.stackexchange.com/questions/666234/fontspecluatex-with-renderer-basic-causes-some-text-to-disappear-sometimes

The font loading features should use Renderer=Harfbuzz here:

tufte-latex/tufte-common.def

Lines 308 to 310 in efb8c8e

	\setmainfont[Renderer=Basic, Numbers=OldStyle, Scale = 1.0]{TeX Gyre Pagella}
	\setsansfont[Renderer=Basic, Scale=0.90]{TeX Gyre Heros}
	\setmonofont[Renderer=Basic]{TeX Gyre Cursor}

I wouldn't force Harfbuzz. For latin scripts node mode is fine. See e.g. the comment here latex3/luaotfload#175 (comment). So simply remove the Renderer option.
