fix(legal): wave-av-sdk's Apache-2.0 licensing cannot reach PyPI at 2.0.0 (LEGAL-001) - #81
Conversation
….0.0 (LEGAL-001) sdk-python/pyproject.toml declares Apache-2.0, but the only release on PyPI -- wave-av-sdk 2.0.0 -- was published carrying `License: MIT` and the MIT trove classifier. Both statements were true at the same version string: $ curl -s https://pypi.org/pypi/wave-av-sdk/2.0.0/json | jq -r '.info.license' MIT $ git show origin/main:sdk-python/pyproject.toml | grep '^license' license = {text = "Apache-2.0"} PyPI releases are immutable. So the correction could never reach a user while the source still said 2.0.0, and the next `sdk-python-v*` tag push would have built 2.0.0 and died on `400 File already exists`. Bumped to 2.0.1 so the Apache-2.0 metadata can actually ship. The published 2.0.0 stays as published -- it cannot be changed, and the gate now says so out loud instead of pretending it agrees. Adds scripts/registry_license_truth.py, which reads the *published* metadata and compares it to source. It draws the line where registry immutability puts it: a collision or a license disagreement at the version about to be published is blocking; a strictly older release that disagrees is immutable history, reported but never failed, so the gate cannot rot into a permanently-red check nobody reads. Stdlib-only with a scoped regex TOML reader for the 3.10 CI leg, where tomllib does not exist yet. Also retitles the changelog: it read "wave-sdk Changelog" while this directory builds "wave-av-sdk". wave-sdk is a different distribution from a different repo (wave-av/sdk-python); conflating them is how one package's license story got read onto the other. Proving runs (local, python 3.14.7 / pytest 9.1.1): # pre-fix tree -- the gate reproduces the defect $ python3 scripts/registry_license_truth.py --pyproject <(git show HEAD:sdk-python/pyproject.toml) [FAIL] version-already-published [FAIL] same-version-license-drift EXIT=1 # post-fix $ python3 scripts/registry_license_truth.py [note] historical-license-drift: 2.0.0 is published as MIT ... stays as published EXIT=0 $ python3 -m pytest -q 31 passed in 0.14s (21 new, 10 pre-existing) Does not touch sdk-python/LICENSE (open PR #80), .github/workflows/publish-pypi.yml (open PR #78) or scripts/license-consistency.mjs (open PR #80).

Do not convert unsupported SPDX identifiers to GPL-3.0-only.
normalize_license("GPL-2.0-only") reaches this fallback and returns "GPL-3.0-only". A source declaration of GPL-3.0-only and a published GPL-2.0-only declaration can then compare as equal. This suppresses license drift. Map only exact supported identifiers. Return UNKNOWN for expressions that the gate cannot compare. Add regressions for GPL-2.0-only and compound SPDX expressions.

🌐 Web query:
Confirm the selected PEP 440 parser treats 2.0and2.0.0as equivalent and orders2.0.0rc1before2.0.0.
💡 Result:
Yes, the PEP 440 specification treats 2.0 and 2.0.0 as equivalent and orders 2.0.0rc1 before 2.0.0 [1]. PEP 440 normalizes version strings, meaning that versions such as 2.0, 2.0.0, and 2.0.0.0 are considered the same version [1]. Consequently, an equality check like 2.0 == 2.0.0 will evaluate to true [1]. Regarding ordering, PEP 440 defines specific rules for release suffixes. Pre-releases (such as aN, bN, and rcN) are ordered numerically before the corresponding stable release [2]. Therefore, 2.0.0rc1 is explicitly considered less than 2.0.0 [1][2]. This ordering is enforced by standard Python packaging tools like the packaging library [2].

Use PEP 440 semantics for registry version comparisons.
check_release_readiness compares raw release strings, so equivalent versions such as 2.0 and 2.0.0 do not collide. Its parse_version also sorts 2.0.0rc1 after 2.0.0, contrary to PEP 440. This can miss upload collisions and misclassify historical license drift. Use a PEP 440-compliant parser for version identity and ordering.

Fail closed when the source license is unknown.
If the source uses an unrecognized license value and has no license classifier, declared_spdx becomes UNKNOWN. For a new version, the function returns no violations and main prints that the source agrees with every published artifact. The gate cannot establish that agreement. Add a blocking source-license-unknown violation before registry comparison.

LEGAL-001 — the license correction that could never ship
The defect
sdk-python/pyproject.tomldeclaresApache-2.0. The only release of this package on PyPI —wave-av-sdk 2.0.0— was published carryingLicense: MITand the MIT trove classifier. Both are true right now, at the same version string:PyPI releases are immutable — a version can never be re-uploaded. Two consequences, both live on
mainbefore this change:wave-av-sdkresolves to2.0.0, and2.0.0says MIT in itsMETADATAforever..github/workflows/publish-pypi.ymlfires onsdk-python-v*tags and builds whateverpyproject.tomlsays. At2.0.0that upload dies on400 File already exists— after the tag is cut, in thepypi-publishenvironment, at the worst possible moment.This is the same-version-string drift called out in LEGAL-001. It is invisible to every gate in the fleet, because every existing gate compares a declaration to another declaration or to the
LICENSEfile beside it. None of them read the registry.The fix
version = "2.0.0"→"2.0.1", with the reason written next to it. The license itself is unchanged —Apache-2.0was already correct here. The published2.0.0stays as published; nothing in this PR pretends otherwise.The gate that keeps it fixed
sdk-python/scripts/registry_license_truth.pyreads the published metadata and compares it to source. It draws the line where registry immutability actually puts it:version-already-publishedsame-version-license-driftsource-classifier-mismatchhistorical-license-driftThat last row is the design decision worth reviewing. An older release that disagrees with today's source is a real fact and it stays printed on every run, but it is not something this repo can fix, so it does not fail the build.
It is stdlib-only and offline: the check runs against a checked-in snapshot of the real PyPI response (
tests/fixtures/pypi_wave_av_sdk.json, captured frompypi.org), so CI is deterministic and cannot go red because an index is having a bad afternoon.--refreshre-fetches it (read-only, unauthenticated GET).tomllibis used where it exists and a scoped[project]-table regex reader stands in on the 3.10 CI leg, wheretomllibdoes not exist yet — a test asserts the two agree.No workflow file is edited. The tests live in
sdk-python/tests/, so the existingpython testgate (pytest -q, matrix 3.10 + 3.12) picks them up as-is.Proving runs
21 of those are new. The load-bearing one is
test_the_2_0_0_collision_is_blocking: it feeds the real captured registry snapshot in beside a source at2.0.0and asserts both blocking codes fire. If that ever stops failing, the gate has stopped seeing the defect that shipped.test_bumping_the_version_clears_the_blockasserts the mirror image, including that the historical drift is still reported and still non-blocking.Also in here
sdk-python/CHANGELOG.mdwas headed "wave-sdk Changelog" while this directory buildswave-av-sdk.wave-sdkis a different PyPI distribution published from a different repository (wave-av/sdk-python), and the two ship a byte-identicalSummaryon the index. Conflating them is precisely how one package's license story gets read onto the other. Retitled, with a note stating the two are unrelated distributions.Contention
Verified against every open PR on this repo before writing — no file in this diff appears in any of them:
sdk-python/LICENSEis MIT text under an Apache-2.0 declaration. That is a real second defect and it is owned by fix(legal): 52 packages declared Apache-2.0 and shipped the MIT text (LEGAL-001) #80; deliberately untouched here..github/workflows/publish-pypi.yml— owned by fix(security): patch runtime deps in sdk-typescript; pin and harden workflow actions #78.scripts/license-consistency.mjs— owned by fix(legal): 52 packages declared Apache-2.0 and shipped the MIT text (LEGAL-001) #80.Rollback
git revertthis commit. The gate is additive and the version bump has never been published, so reverting restores2.0.0in source with no registry side effects. Nothing here publishes, mints, or deploys anything —--refreshis the only network call and it is a read-only GET.Not fixed here, needs a decision
wave-av-sdk(this repo) andwave-sdk(wave-av/sdk-python) are two PyPI packages shipping the same description for the same product. Which one is canonical is a product call, not a lint fix — flagged for the operator rather than guessed at.🤖 Generated with Claude Code
