- Line 554: Normalize the source-distribution filename’s name component in
default_build_sdist to match the canonical archive naming convention, using the
existing canonicalize_name transformation rather than the raw requirement name.
Keep the existing arcname_root behavior unchanged.
In `@tests/test_tarballs.py`:
- Around line 113-118: Extend the regression coverage around test_arcname_root
to call default_build_sdist with Requirement("Foo.Bar==1.0") and a
monorepo-style build_dir instead of invoking tarballs.tar_reproducible directly.
Assert that the archive filename uses the normalized foo_bar-1.0 name and that
its complete top-level entry set is exactly {"foo_bar-1.0"}.

When a package specifies build_dir in settings (monorepo subdirectory),
default_build_sdist was creating tarballs rooted at the build_dir's name
instead of {name}-{version} as required by PEP 427.
For example, mlserver-xgboost with build_dir=runtimes/xgboost/ produced
mlserver-xgboost-1.7.1.tar.gz unpacking to xgboost/, causing name collisions
and identity mismatches.
Changes:
- Add arcname_root parameter to tar_reproducible() to explicitly set the
top-level directory name in archives
- Pass normalized {name}-{version} as arcname_root in default_build_sdist()
- Add test to verify correct archive structure with arcname_root
Fixes python-wheel-build#1315

The test_default_build_sdist_normalizes_name_and_root test was failing with FileExistsError because it was trying to create a tarfile with the same name twice. Delete the first tarfile before creating the second one for the archive root verification. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com> Signed-off-by: Justin Larkin <jlarkin@redhat.com>

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Test the default_build_sdist archive result.
The mock at Line 819 bypasses the call that receives arcname_root. The later direct call hard-codes "foo_bar-1.0", so this test passes even if default_build_sdist stops passing the archive root.
Remove this mock. Open sdist_file after default_build_sdist returns. Assert that its top-level directory is exactly {"foo_bar-1.0"}.
As per path instructions, tests must verify the intended behavior.
