Some mtime checks are reproducibly off by a tiny bit and for the same files. Please note that the file content did not change (no difference in MD5 hash). Overall I'd classify most files as cache files that are changing by design and therefore maybe shouldn't even be checked like static files. I have no idea if this is caused by qcheck or the ebuilds.

The MTIME errors for python shouldn't be like that, and indicates something has tampered with them. The other packages are indeed cache files that have dynamic changing MTIMES, and I would agree something might need to be done about those. but the python part means something is changing .pyc files = valid discrepancy
I am unable to reproduce the issue you are experiencing with python. % sudo qcheck -v dev-lang/python Checking dev-lang/python-3.12.3 ... * 8236 out of 8236 files are good Checking dev-lang/python-3.11.9 ... * 8421 out of 8421 files are good Checking dev-lang/python-2.7.18_p16-r2 ... * 4565 out of 4565 files are good It seems likely that the file timestamps on your system have been messed with somehow.
what filesystem do you use?
I can't reproduce the python issues, so "works for me" is OK. Maybe I had an python emerge running at that time. My ext4 fs mounted with noatime,discard,commit=600 P. S.: What's the correct approach for patches regarding the cache file cases like libs/gdk-pixbuf? It is not obvious from typical ebuilds, and mocking with /var/db/pkg/x/y/CONTENTS does not feel correct.
