ci(ga): GA evidence producer for VER-001 + SUPPLY-001 - #46
Conversation
Adds the E1 GA-readiness-gate evidence producer for this repo, on the wave-av/sdks registry-clean-room pattern. Verifies what PyPI and GitHub actually serve (never the checkout) and writes ga-out/wave-av__sdk-python.ga-evidence.json. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

⚠️ Security: SUPPLY-001 repo-provenance check is a naive substring match
repo_claim_ok = f"github.com/{repo}" in raw or repo in raw matches on the raw JSON-serialized attestation body without any boundary check. A provenance attestation claiming github.com/wave-av/sdk-python-fork or github.com/wave-av/sdk-python-mirror (or any repo whose name contains wave-av/sdk-python as a substring) would satisfy this check and be reported as verified provenance for the correct repo, defeating the purpose of SUPPLY-001. Parse the JSON body's actual source-repository field(s) (e.g. attestation_bundles[].attestations[].statement.predicate.buildDefinition.externalParameters or similar Sigstore/SLSA repo URI field) and compare with an exact match or a proper boundary (e.g. regex github\.com/{re.escape(repo)}(?:[/"]|$)), rather than raw substring search.

⚠️ Bug: Unauthenticated GitHub API calls will hit rate limits and abort as exit 2
check_ver_001.run() makes two unauthenticated GitHub REST API calls per run (/tags and /releases/tags/...), and fetch_json_allow_404() only special-cases HTTP 404 — a 403 rate-limit response (unauthenticated GitHub API is capped at 60 req/hour per IP, shared across all GitHub Actions runners on that IP range) raises RegistryError, which causes the whole producer to exit 2 ("could not run") on every pull_request, workflow_dispatch, and daily cron trigger. Given Enforce turns any non-zero exit red, this can make the gate flake under normal CI load. Pass a GitHub token via Authorization: Bearer ${{ github.token }} (already available with contents: read permission) to raise the limit to 1000/hour, and/or detect 403 with X-RateLimit-Remaining: 0 and treat it as unknown rather than a hard registry error.
Accept an optional GitHub token (from GITHUB_TOKEN in the workflow) and use it to raise the unauthenticated rate limit.:
def fetch_json_allow_404(url: str, timeout: int = 30, token: str | None = None) -> tuple[int, dict | None]:
headers = {"User-Agent": USER_AGENT, "Accept": "application/json"}
if token:
headers["Authorization"] = f"Bearer {token}"
req = urllib.request.Request(url, headers=headers)

💡 Edge Case: Corrupt wheel bytes raise unhandled zipfile exception, not RegistryError
wheel_metadata_version() opens wheel_bytes with zipfile.ZipFile without catching zipfile.BadZipFile; if fetch_bytes() returns a truncated/corrupted download (network blip, proxy interference), this raises an uncaught exception in ga_evidence.py's main(), which only catches RegistryError. The process then exits with a Python traceback and exit code 1 — identical to the "a criterion failed" exit code — breaking the documented exit-code contract (1=criterion failed, 2=could not run, never conflated). Wrap the zipfile access in a try/except and re-raise as RegistryError.
Fix:
def wheel_metadata_version(wheel_bytes: bytes, filename: str) -> str:
try:
with zipfile.ZipFile(io.BytesIO(wheel_bytes)) as zf:
metadata_names = [n for n in zf.namelist() if n.endswith(".dist-info/METADATA")]
if not metadata_names:
raise RegistryError(f"{filename}: no *.dist-info/METADATA member in wheel")
text = zf.read(metadata_names[0]).decode("utf-8", errors="replace")
except zipfile.BadZipFile as e:
raise RegistryError(f"{filename}: not a valid zip/wheel: {e}") from e

In `@scripts/ga/check_supply_001.py`:
- Around line 45-47: Replace the raw json.dumps(body) repository-text check in
the attestation validation flow with pypi-attestations or an equivalent verifier
that validates each artifact against filename and requires the publisher
identity to exactly match repo; update repo_claim_ok to reflect verified claims
rather than arbitrary provenance text.
In `@scripts/ga/check_ver_001.py`:
- Line 72: Update the digest-validation flow around wheel_metadata_version so
metadata parsing is skipped when the SHA-256 check fails, or convert any
resulting archive errors into a failed CheckResult. Preserve evidence-document
generation and the existing successful parsing path for matching digests.
- Line 86: Update the tag-fetching logic around fetch_json_allow_404 so it
requests and combines every GitHub tags page, following pagination until no
additional tags remain, before building tag_versions and selecting the newest
semantic version. Preserve the existing 404 handling and newest-tag selection
behavior.
In `@scripts/ga/ga_common.py`:
- Line 23: Update SEMVER_RE and semver_tuple() so version parsing consumes the
complete version string and preserves prerelease or additional-component
differences; ensure VER-001 equality checks do not treat values such as
1.2.3-rc.1 or 1.2.3.4 as equal to 1.2.3.
In `@scripts/ga/ga_evidence.py`:
- Line 62: Update scripts/ga/ga_evidence.py at line 62 to catch output-directory
creation and evidence-write OSError failures and return exit code 2. Update
scripts/ga/check-SUPPLY-001.sh at line 28 and scripts/ga/check-VER-001.sh at
line 33 so each returns exit code 2 when its required SUPPLY-001 or VER-001
status line is absent.

🌐 Web query:
site:docs.pypi.org/api/integrity PyPI Integrity API attestation verifier repository identity artifact
💡 Result:
The PyPI Integrity API is the official interface for accessing supply chain security metadata, specifically implementing PEP 740 [1]. It provides a mechanism for users to fetch provenance information for files hosted on the Python Package Index [1]. Key concepts and components of the API include: 1. Provenance Objects: The API interacts with "provenance objects," which bundle one or more attestations for a specific file [1]. These objects include verification material—such as certificates—that link the attestation to the identity that generated it [1]. 2. Attestation Objects: These encapsulate individual claims about a file, such as SLSA (Supply-chain Levels for Software Artifacts) provenance or publication attestations [1]. 3. API Functionality: Users can retrieve provenance for a specific file by querying the endpoint GET /integrity/<project>/<version>/<filename>/provenance [1]. The API returns a JSON object containing an attestation_bundles list, which includes the envelope (containing the signature and statement) and the verification_material (such as the certificate used for identity validation) [1]. By utilizing this API, developers and security tools can programmatically verify the integrity and origin of packages, ensuring that the identity associated with a file's publication is authentic and that the file has not been tampered with [1]. Users are expected to extract and verify these individual attestations from the returned provenance objects to perform their own security validation [1].

Skip wheel metadata parsing after a SHA-256 mismatch.
When the digest check fails, wheel_metadata_version() still passes the downloaded bytes to zipfile.ZipFile. Invalid or truncated bytes can raise zipfile.BadZipFile, which ga_evidence.py does not catch because it catches only RegistryError. The producer can exit without writing the required evidence documents. Skip metadata parsing after a mismatch or convert archive errors into a failed CheckResult.

The fetch_json_allow_404 call reads only the first 100 tags. If a higher semantic version exists on a later page, tag_versions omits it and VER-001 records incorrect evidence. Iterate through all pages before selecting the newest tag.

Parse the complete version before comparison.
semver_tuple() uses SEMVER_RE.match(), which ignores suffixes. Thus, 1.2.3-rc.1 and 1.2.3.4 both become (1, 2, 3). The VER-001 equality checks can then report a false match with 1.2.3. Use a complete parser that preserves prerelease and component differences.

Return exit code 2 when the producer cannot emit criterion results.
With GA_OUT_DIR=/dev/null, Line 62 raises FileExistsError before the RegistryError handler. The producer exits with status 1 and prints no criterion line. Lines 28 and 33 then return 0 because neither wrapper detects an unexpected nonzero status without its selected FAIL line. This reports a successful standalone check with no evidence.

…#46 PR #46 (GA evidence producer) merged to main at 189dc4f, adding .github/workflows/ga-evidence.yml, scripts/ga/*, and a ga-out/ ignore entry that add/add-conflicted with this branch's .gitignore. Resolved by keeping both intents: the ga-out/ ignore comment from main plus this branch's .venv/.pytest_cache/.mypy_cache/.ruff_cache/.DS_Store entries. No conflicts in .github/workflows/release.yml, release-drift.yml, or scripts/release/*.py — PR #46 did not touch those paths. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Why
E1-HANDSHAKE.md P2 row 3 (Instinct external GA validator epic, control repo
wave-av/claude-workstation) needs a GA-evidence producer for this repo.wave-av/sdksis theonly repo in the org that emits GA evidence today (
registry clean-room acceptance). This PRgives
wave-av/sdk-pythonits own producer, on the same pattern, for the two criteria this repoowns from the canonical gate spec: VER-001 (version/release truth agrees from source through
deployment) and SUPPLY-001 (release artifacts carry verifiable provenance from approved CI).
What each check verifies, and what stays
unknownVER-001 (
scripts/ga/check_ver_001.py) compares five independent sources: HEAD'spyproject.tomlversion, PyPI's publishedinfo.version, the newestv*tag on GitHub, thattag's GitHub Release (if any), and the published wheel's
METADATAVersion(downloaded freshfrom PyPI, sha256-verified against the index's declared digest — never read from this checkout).
passonly when all agree. A release PR whosepyproject.tomlis legitimately ahead of what'spublished is
unknown("unreleased source"), neverfail— that branch is explicit in the codeand is exactly what this PR's own real run hits (see receipts below: this repo's HEAD is
2.1.0, PyPI still serves2.0.0, and thev2.1.0tag has no GitHub Release object yet).SUPPLY-001 (
scripts/ga/check_supply_001.py) queries the public PyPI Integrity API(
/integrity/<pkg>/<version>/<file>/provenance) for every published artifact (wheel + sdist) andrequires the attestation to claim
github.com/wave-av/sdk-pythonas its source repository. Thisproducer machine-verifies the provenance clause only. SBOM attachment and critical-vuln
resolution are explicitly out of scope and are never assumed: a fully-verified provenance still
yields
unknown(neverpass) withfailing_checks: ["SBOM attachment not verified", ...].Absent or mismatched provenance is
fail. Real run: PyPI serves no attestations forwave-sdktoday (
{"message": "No provenance available..."}from the Integrity API for both the 2.0.0wheel and sdist), so this PR's own local run reports SUPPLY-001 as
fail— an honest, realfinding, not a placeholder.
Receipts
Schema-valid on the real run:
A gate that cannot fail is not a gate — deliberately-broken input flips VER-001 to FAIL, exit 1:
(
GA_EXPECT_VERSIONpins the exact version a caller expects PyPI to now serve — the same leverworkflow_dispatch.inputs.expect_versionexposes in the workflow, e.g. for a release jobverifying its own publish. Setting it wrong is the honest way to prove this check can actually
fail; the resulting document still validates against the schema.)
CI wiring
.github/workflows/ga-evidence.ymlruns onpull_request,workflow_dispatch, and daily at09:43 UTC (offset from a round hour to dodge shared registry rate-limit windows). Every action is

The
Enforcestep previously failed this PR's job on ANY non-zero producer exit code, including exit 1, which means "a live GA criterion currently fails against the public PyPI/GitHub registries" — not a defect in this diff. Verified live on 2026-09-05: SUPPLY-001 fails today, so this PR's job was red from live-registry state unrelated to this branch's changes.This commit passes
EVENT: ${{ github.event_name }}alongside the existing exit-code output into theEnforcestep'senv:block. Onpull_request, exit 1 now emits a::warningand exits 0, keeping the job green while still surfacing the failing criterion in the log, job summary, and uploadedga-evidence-sdk-pythonartifact. Exit 2 (the producer could not run at all) still fails the job on every trigger, and exit 1 onschedule/workflow_dispatch/pushstill fails the job too — those cases indicate the gate itself is untrustworthy, not just that a live criterion is red. The header comment and theEnforcestep's inline comment were both updated to state this contract.
