…BI infix support Document in .agents/rules/windows.md that platform.machine() returns uppercase on Windows and requires .lower() normalization, and that CPython on Windows natively supports loading SOABI ABI-tagged .pyd files with platform tags.
Agents resolving platform tags on Windows may encounter uppercase strings from platform.machine(), leading to mismatch errors when matching PEP 508 tags. Additionally, agents lacked guidance on Windows CPython native support for SOABI ABI infix tags. Document the requirement to normalize platform.machine() to lowercase and clarify native SOABI platform tag support for Windows CPython.
