looks like lpdf-pdx.xml is used in the end:
backend > xmp > using file 'C:/data/context/bin/beta-win64/tex/texmf-context/tex/context/base/mkiv/lpdf-pdx.xml'
only \enabletrackers[resolvers.details] adds the information "file not readable", likely without any real effect.
I'm getting different results on windows and linux in more complex setup and "file not readable" was the only difference in log files.
That's why I became interested in "file not readable" information, which seems to be misleading.
In the end all files are are listed in
system > start used files
section and context doesn't complain it cannot open or read those files (file not found).
The mystery of the log information remains unresolved.
Thank you,
