Every release since v0.20.16 has uploaded 12 wheels but no sdist. The
underlying failure is a 400 from PyPI:
400 License-File NOTICE does not exist in distribution file
headroom_ai-X.Y.Z.tar.gz at headroom_ai-X.Y.Z/NOTICE
Two-part regression:
1. The hatch -> maturin migration in 2a91cbb (single-wheel maturin build
backend, May 4) replaced `[tool.hatch.build.targets.sdist].include`,
which listed both `LICENSE` and `NOTICE`, with maturin's own include
directive that only carried `LICENSE` over. Maturin's PEP 639 license
auto-discovery still emits `License-File: NOTICE` into the sdist's
PKG-INFO (because NOTICE exists at the project root and matches the
default glob), so the sdist tarball declares a license file it
doesn't physically contain. PyPI's PEP 639 validator rejects with
400. Wheels were unaffected because maturin auto-injects both files
into `*.dist-info/licenses/`.
2. CI showed "publish-pypi" green for ~22 releases despite this break
because twine was bailing earlier with `400 File already exists` on
the wheels (the version detector kept computing the same v0.21.5).
PR #412 added `skip-existing: true` (May 6) to make wheel re-uploads
idempotent. With wheels now silently skipping, twine proceeded to
upload the sdist for the first time in three weeks - and the
dormant License-File error surfaced as a hard 400.
Fix:
- Add `NOTICE` alongside `LICENSE` in `[tool.maturin].include` for the
`sdist` format. Both files now ship in the tarball, matching what
PEP 639 already declares in PKG-INFO.
- Replace the existing "verify sdist contains LICENSE" check with a
generic "every License-File entry in PKG-INFO resolves to a real
tarball member" check. This catches the same bug class for any
future addition (COPYING, AUTHORS, etc.) without another bespoke
literal.
