macOS has blocked passing down DYLD_LIBRARY_PATH for some time but only for
"restricted" binaries (this is part of what SIP does). I should see if someone
the verification script is picking up the wrong Python. Here's my system
python3 (which is restricted):
```console
$ ls -lO /usr/bin/python3
-rwxr-xr-x 78 root wheel restricted,compressed 118864 Sep 25 00:03
/usr/bin/python3*
$ DYLD_LIBRARY_PATH="osmenthe" /usr/bin/python3
Python 3.9.6 (default, Aug 8 2025, 19:06:38)
[Clang 17.0.0 (clang-1700.3.19.1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ["DYLD_LIBRARY_PATH"]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

```
Here's my brew python3 (not restricted)
```console
$ ls -lO (command -v python3)
