[oberstet]

this is fixed in v25.10.2:

https://github.com/crossbario/autobahn-python/tree/v25_10_2
https://pypi.org/project/autobahn/25.10.2/
https://autobahn.readthedocs.io/en/v25.10.2/

the wheels published (and autobahn NVX in general) now uses a safe CPU arch compile target that will work on any x86-64 / ARM64 younger than ~ 10 years
