You could just .split it:
>>> Path('logs/date.log.txt').stem.split('.')[0]
'date'
os.path works just as well:
>>> os.path.basename('logs/date.log.txt').split('.')[0]
'date'
It passes all of the tests:
In [11]: all(Path(k).stem.split('.')[0] == v for k, v in {
....: 'a': 'a',
....: 'a.txt': 'a',
....: 'archive.tar.gz': 'archive',
....: 'directory/file': 'file',
....: 'd.x.y.z/f.a.b.c': 'f',
....: 'logs/date.log.txt': 'date'
....: }.items())

Why not go recursively?

Python's pathlib Module: Taming the File System – Real Python
January 11, 2025 - You’re using .with_stem() to create the new filename without changing the extension. The actual copying takes place in the highlighted line, where you use .read_bytes() to read the content of source and then write this content to destination using .write_bytes(). While it’s tempting to use pathlib for everything path related, you may also consider using shutil for copying files.
