These packages are supposed to be co-installable, and the file in question should be identical across architectures. However, it _is_ an autogenerated file and that increases the risk of mismatches when the generator doesn't behave exactly the same.

I just verified this, and the file is in fact identical between release architectures amd64, arm64 and ppc64el.
riscv64 doesn't match, because it was built with a different SIP version:

--- pynest2d.pyi.amd64  2025-12-06 00:45:50.000000000 +0100
+++ pynest2d.pyi.riscv64        2025-12-08 03:09:28.000000000 +0100
@@ -1,6 +1,6 @@
  # The PEP 484 type hints stub file for the pynest2d module.
  #
-# Generated by SIP 6.14.0
+# Generated by SIP 6.15.0

There are no other mismatched lines in the file.

This should be easy to fix - I committed a patch that removes the version info from the file:

@myon Could you upload 5.0.0-4 when you have time?
Thank you!
