As for the interaction patching, in the following example I can't figure out how to have, for the chapter lines, only "CHAPTER 1" being the interaction and not "the title" + "the dots line" + "the page number", as it is the case with this code.The example is minimal, but I left everything I am afraid could be dropped by a solution.
Thanks for help !

\setupinteraction[state=start]
\setuplabeltext[chapter=CHAPITRE~]
\setupcombinedlist[content][	level=3,	alternative=c,	]	\unprotect\define[3]\ChapterList{\vbox{	\setuplocalinterlinespace[line=2.8ex]	\listparameter\c!before	\leftskip\listparameter\c!margin	\noindent\currentlistsymbol\crlf#2\enspace\listdots\enspace#3	\par	\listparameter\c!after	\setuplocalinterlinespace[line=4.2ex]	}}\protect
\setuplist[chapter][	label=yes,	alternative=vertical,	command=\ChapterList,	interaction=all,	]	\starttext
\startfrontmatter\placecontent\stopfrontmatter
\startbodymatter\chapter{CHAPTER}\section{SECTION}\subsection{SUBSECTION}\stopbodymatter
\stoptext
