📝 Walkthrough

Walkthrough

This PR modernizes the ext4 library's type system by introducing a basetype attribute to enum classes and updating struct field definitions to use the underlying ctype instead of enum wrappers. Python 3.10 support is dropped to 3.11+, while CI is expanded to build wheels for riscv64 and s390x architectures with musl support, adding automated wheel testing.

Changes

Cohort / File(s)	Summary
Type System Modernization ext4/enum.py, ext4/blockdescriptor.py, ext4/directory.py, ext4/htree.py, ext4/inode.py, ext4/superblock.py	Added basetype attribute to TypedCEnumeration factory; updated struct field definitions across multiple files from enum types to their underlying .basetype for proper ctypes storage. Simplified enum coercions from assert_cast(...) calls to direct enum constructor calls.
CI Workflow Enhancements .github/workflows/build.yaml, wheel.sh	Adjusted workflow formatting; removed Python 3.10 from CI matrix; expanded build-wheel matrix to include riscv64 and s390x architectures; enabled musl builds alongside glibc; added conditional Docker image selection for riscv64; integrated test-image as build dependency.
Test Infrastructure & Scripts test-wheel.sh, test.py	Added new wheel testing script that selects wheels by architecture/libc/Python version, builds Docker commands with platform mapping, installs binfmt support for non-x86_64 arches, and executes tests. Updated test expectations for dx_root_info.hash_version type and added exception-safety validation.
Package Metadata pyproject.toml	Bumped version from 1.3.1 to 1.3.2; raised requires-python from ≥3.10 to ≥3.11; removed Python 3.10 Trove classifier; cleared test optional dependencies list.

Poem

🐰 Our types now base, our arches grow wide,
riscv64 and s390x along for the ride,
Wheels tested on musl, Python 3.11 and beyond,
The enum's foundation: a robust new bond! ✨
