Why

Instinct's GA validator found two real gaps on this repo:

  • VER-001 — no GitHub Release exists for the current tag (v2.1.0), and PyPI is a version behind (2.0.0).
  • SUPPLY-001 — the published wave-sdk package carries no provenance/attestation.

Jake's 2026-09-05 decision: "agents build release-on-tag + provenance PRs, and we need to ensure it's always codified workflows so we don't ever have drifts." This PR is that codification: a tag-triggered release pipeline that publishes with PEP 740 attestations and creates the missing GitHub Release, plus a standing drift gate so this class of gap cannot silently recur.

What changed

.github/workflows/release.yml (rewritten, folds in the existing publisher)

The repo already had a release.yml that ran a PR dry-run (build + twine check + install + import) and, on v* tag push, built and published to PyPI via Trusted Publishing (OIDC, no token). I did not leave two publishers — that file is rewritten in place; there is still exactly one pypa/gh-action-pypi-publish step in this repo, in the same file.

New three-job shape, each with its own minimal, explicit permissions::

  1. verify (permissions: {contents: read}) — resolves the target tag from either the tag-push ref or a workflow_dispatch tag input (strictly validated against ^v[0-9]+\.[0-9]+\.[0-9]+(-[0-9A-Za-z.]+)?$ before it is ever interpolated into a ref:, to close the ref-injection class of bug), checks out that exact tag, runs scripts/release/assert_version.py to fail loud if the tag, pyproject.toml version, and wave_sdk.__version__ disagree, installs with dev,realtime,x402 extras, runs the full pytest suite, builds sdist+wheel, and twine checks them.
  2. publish (permissions: {id-token: write, contents: read}) — PyPI Trusted Publishing via pypa/gh-action-pypi-publish@ed0c53931b1dc9bd32cbe73a98c7f6766f8a527e # v1.13.0 with attestations: true (PEP 740 provenance), no token anywhere. Before publishing it calls scripts/release/pypi_version_exists.py against the live PyPI JSON API; if that exact version is already published, the publish step is skipped with a ::notice:: log line and the job still succeeds — a re-run (e.g. the workflow_dispatch backfill below) is idempotent, not a hard failure.
  3. release (permissions: {contents: write}) — creates the GitHub Release for the tag via gh release create ... --generate-notes with the sdist+wheel attached. If the release already exists it uploads the assets onto it (gh release upload --clobber) instead of failing, so re-runs are idempotent.

Triggers: push: tags: ["v*"] and workflow_dispatch with a required tag input, specifically so the existing v2.1.0 tag (pushed before this workflow existed) can be backfilled:

gh workflow run release.yml --repo wave-av/sdk-python --ref main -f tag=v2.1.0

Every uses: is pinned to a 40-character commit SHA with the human version in a trailing comment. I verified each SHA against the GitHub API directly (not guessed) — actions/checkout@df4cb1c...# v6.0.3, actions/setup-python@a309ff8...# v6.2.0, actions/upload-artifact@ea165f8...# v4.6.2 (all three carried over unchanged from the prior file), actions/download-artifact@3e5f45b2cfb9172054b4087a40e8e0b5a5461e7c # v8.0.1 (new, resolved via gh api repos/actions/download-artifact/tags), and pypa/gh-action-pypi-publish@ed0c539...# v1.13.0.

Disclosed tradeoff: the old release.yml also ran its build+twine-check dry-run on every pull request. The new release.yml only triggers on tag-push / workflow_dispatch (a job that checks out a real git tag cannot sanely run against a PR ref). smoke-install.yml (build wheel + install + import, on every PR across the 3.9/3.12/3.13 matrix) and python-tests.yml (full pytest suite, every PR) already cover the substance of that dry-run; the one thing genuinely lost is a PR-time twine check. I judged that an acceptable, disclosed tradeoff rather than fabricating a way to checkout a tag from a PR context — happy to add twine check to smoke-install.yml in a follow-up if you'd rather keep it on the PR path.

.github/workflows/release-drift.yml (new)

Runs on push to main, daily (cron: "17 6 * * *"), and workflow_dispatch. Single job, permissions: {contents: read}, that runs scripts/release/check_drift.py. Fails loud (exit 1) the moment any of these disagree: latest v* git tag, pyproject.toml version, PyPI's latest published version, GitHub Release existence for the latest tag, and PEP 740 attestation coverage (urls[].provenance non-null on every published file, per PyPI's own JSON API). Exits 2 (never conflated with "in sync") if any source is unreadable — a network blip on PyPI never gets treated as "everything's fine."

scripts/release/ (new, stdlib-only, called by both workflows and runnable locally)

  • check_drift.py — the drift comparison above. python3 scripts/release/check_drift.py.
  • assert_version.py — tag vs. pyproject.toml vs. wave_sdk.__version__, used by verify.
  • pypi_version_exists.py — live PyPI existence check for one version, used by publish to decide skip-vs-publish.

All three are plain Python 3.11+ stdlib (tomllib, urllib.request, subprocess, argparse) plus the git/gh CLIs — no third-party dependency, so they run identically in CI and on a laptop.

Live local receipts (run in /tmp/sdkpy-release, a git worktree off origin/main, today 2026-09-05)

$ python3 scripts/release/check_drift.py
[source] latest git tag           : v2.1.0 (version 2.1.0)
[source] pyproject.toml version    : 2.1.0
[source] PyPI latest version        : 2.0.0
[source] GitHub Release for v2.1.0   : MISSING
[source] PyPI 2.0.0 attestations : NONE (urls[].provenance is null on every file)

RESULT: DRIFT DETECTED
 - DRIFT: PyPI latest (2.0.0) != latest tag version (2.1.0)
 - DRIFT: no GitHub Release exists for tag v2.1.0
 - DRIFT: PyPI 2.0.0 is missing PEP 740 attestation/provenance on: ['wave_sdk-2.0.0-py3-none-any.whl', 'wave_sdk-2.0.0.tar.gz']
exit=1

This is the honest first run and matches exactly what the GA validator reported (VER-001 + SUPPLY-001). I confirmed the urls[].provenance field is real and currently null by curling https://pypi.org/pypi/wave-sdk/2.0.0/json directly, not by assumption.

$ python3 scripts/release/assert_version.py v2.1.0
tag              : v2.1.0 (version 2.1.0)
pyproject.toml   : 2.1.0

actionlint (v1.7.12, /opt/homebrew/bin/actionlint) is installed on this machine — both new/changed workflow files lint clean.

One-time operator step (I cannot do this — no publish secrets, decision IGV-D-010)

On pypi.org, as the wave-sdk project owner:

  1. Go to https://pypi.org/manage/project/wave-sdk/settings/publishing/
  2. Under "Add a new publisher" → GitHub:
    • Owner: wave-av
    • Repository name: sdk-python
    • Workflow name: release.yml
    • Environment name: (leave blank)
  3. Save. No token, no secret — this authorizes OIDC-based Trusted Publishing from that exact repo + workflow only.

Backfilling the existing v2.1.0 tag

Once the Trusted Publisher above is registered:

gh workflow run release.yml --repo wave-av/sdk-python --ref main -f tag=v2.1.0

This runs verifypublish (uploads wave-sdk==2.1.0 with PEP 740 attestations) → release (creates the missing v2.1.0 GitHub Release with the built sdist+wheel attached), closing both VER-001 and SUPPLY-001 in one run.

What I could not verify / gaps

  • I do not have access to the mcp__corridor__analyzePlan tool in this worker session (it was not present in my available tool set, and no ToolSearch tool was available to load it) — the plan-analysis step my global instructions call for could not be executed. Flagging this honestly rather than silently skipping it.
  • I have not triggered the workflow against real PyPI/GitHub Release APIs (that requires the operator's Trusted Publisher registration above, and would actually publish 2.1.0 and create a public release — an irreversible action I should not take without that authorization in place first).
  • CI on this PR: the two new/changed workflow files only run on tag-push / workflow_dispatch, so they will not execute as PR checks; python-tests.yml, smoke-install.yml, python-lint.yml, foundation-gate.yml, and public-repo-guard.yml will run as usual and are unaffected by this change (verified: grep -rln "gh-action-pypi-publish\|twine upload\|pypi" .github/workflows/ returns only release.yml).

Note

High Risk
Changes the production release and PyPI publish path (OIDC, attestations, idempotent publish) and tightens which refs can be released; misconfiguration could block or incorrectly gate public releases.

Overview
Replaces the prior tag/PR release workflow with a four-job pipeline (resolve-refverifypublishrelease) that only runs on v* tag pushes or workflow_dispatch with a required tag input (PR dry-run removed).

The new resolve-ref job validates dispatch/push tags (semver shape, existence, commit must be an ancestor of origin/main) and passes a fixed commit SHA to all later checkouts. verify runs assert_version.py, full pytest, build, and twine check, then uploads dist artifacts. publish uses PyPI Trusted Publishing with attestations: true, skips upload when pypi_version_exists.py says the version is already on PyPI. release creates or updates the GitHub Release and uploads sdist/wheel idempotently.

Adds release-drift.yml (on main push, daily cron, manual) calling check_drift.py to fail when git tag, pyproject.toml, PyPI latest, GitHub Release for the tag, or PEP 740 provenance on PyPI disagree; unreadable sources exit 2 instead of passing.

New stdlib scripts/release/ helpers (assert_version.py, check_drift.py, pypi_version_exists.py) support local runs. .gitignore gains common Python/tool caches.

Review in cubic

Addendum — 2eef32a

Hardened the dispatch-tag trust path per the reference implementation on wave-av/sdk PR #121 (commit 293e0df):

  • Split tag resolution out of the verify job into its own dedicated resolve-ref job, matching the reference shape. It now validates the tag in three stages before it is trusted for anything downstream: (1) format — full-anchored regex ^v[0-9]+\.[0-9]+\.[0-9]+(-[0-9A-Za-z.]+)?$ (unchanged from before, now run in resolve-ref); (2) existence — new: git rev-parse --verify --quiet "refs/tags/$TAG^{commit}", failing loud with ::error:: if the tag doesn't resolve to a real commit; (3) trust — new: git merge-base --is-ancestor "$SHA" origin/main, failing loud with ::error:: if the tag's commit isn't reachable from origin/main. Outputs both tag and sha.
  • resolve-ref's checkout uses fetch-depth: 0 (full history + tags), since the existence/ancestry checks need real git objects.
  • Every downstream actions/checkout in verify, publish, and release now pins ref: to ${{ needs.resolve-ref.outputs.sha }} (the validated commit) instead of refs/tags/${{ ...outputs.tag }} (the mutable tag name). persist-credentials: false was already set and is unchanged.
  • Confirmed no dependency cache is read or written anywhere in this workflow: no cache: key on either actions/setup-python step, and no actions/cache usage anywhere in release.yml — nothing to remove.
  • PyPI Trusted Publishing (OIDC, PEP 740 attestations), per-job minimal permissions:, and the existing exact-SHA action pins are all unchanged.
  • Inputs flow only via env:/job outputs: — nothing is interpolated into a shell body.

Validation (in /private/tmp/sdkpy-release, a worktree on this branch):

$ python3 -c 'import yaml,sys; yaml.safe_load(open(sys.argv[1]))' .github/workflows/release.yml
OK
$ actionlint .github/workflows/release.yml
(no output, exit 0)

Live logic test against this repo's real tags (extracted the resolve-ref step's shell to a standalone script and ran it in this worktree): DISPATCH_TAG=v2.1.0 resolved to v2.1.0 -> 6b1afc10deba698187b00c76633365d2265e6b74 (exit 0, confirmed an ancestor of origin/main). A malformed tag (notatag) and a nonexistent tag (v99.99.99) both failed loud with the expected ::error:: message (exit 1).

CodeAnt-AI Description

Make tagged releases verifiable, provenance-attested, and safe to rerun

What Changed

  • Tag pushes and manual backfills now verify that the tag is valid, exists, matches the package versions, and points to code merged into main before publishing
  • Releases run the full test suite, build checks, and version consistency checks before any package is published
  • PyPI publishing uses Trusted Publishing with PEP 740 attestations; rerunning an already-published version skips the upload instead of failing
  • A GitHub Release is created automatically with the built packages, or updated when it already exists
  • A scheduled and main-branch drift check now detects mismatches between tags, project versions, PyPI, GitHub Releases, and package provenance

Impact

✅ Fewer failed release reruns
✅ Verified package provenance on PyPI
✅ No releases from unmerged tag code
✅ GitHub Releases stay aligned with published packages

Summary by CodeRabbit

  • Release Management

    • Releases can now be initiated from version tags or manually with a specified tag.
    • Published packages are validated, accompanied by generated release notes, and attached distribution files.
    • Existing package versions are detected to prevent duplicate publication.
  • Reliability

    • Automated checks compare repository, package registry, and GitHub release versions.
    • Package provenance is verified to improve release integrity.
    • Scheduled monitoring identifies release inconsistencies.

Walkthrough

The pull request adds release validation scripts, replaces the release workflow with tag-based verification and publication, creates GitHub Releases, and adds scheduled checks for drift between Git, PyPI, and GitHub Releases.

Changes

Release automation and drift detection

Layer / File(s) Summary
Release validation tooling
scripts/release/assert_version.py, scripts/release/pypi_version_exists.py, .gitignore
The new scripts validate package versions and check exact PyPI version existence. Ignore rules cover Python and build artifacts.
Verified release execution
.github/workflows/release.yml
The workflow validates tags and package versions, runs tests, builds and verifies distributions, publishes missing versions with Trusted Publishing, and creates or updates GitHub Releases.
Release drift monitoring
scripts/release/check_drift.py, .github/workflows/release-drift.yml
The drift checker compares repository, PyPI, and GitHub Release state and validates PyPI provenance. The workflow runs it on pushes, daily, and manual dispatches.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to f2616

The documented backfill cannot satisfy the new provenance gate, and the drift monitor can report incorrect failures for valid release state or malformed upstream responses. These issues should be resolved before relying on the pipeline.

⚠️ Bug: Concurrency group differs between tag-push and workflow_dispatch runs

The concurrency.group is release-${{ github.event.inputs.tag || github.ref }}. For a tag push, github.ref resolves to refs/tags/v2.1.0, but for a workflow_dispatch backfill of the same tag, the group resolves to just v2.1.0. These are different strings, so GitHub Actions treats them as unrelated concurrency groups — a tag-push run and a workflow_dispatch backfill run for the same tag can execute concurrently. That undermines the PR's own idempotency goal (the documented backfill use case): the publish job's check-then-skip against PyPI (pypi_version_exists.py) has a TOCTOU window, and two concurrent gh release create/gh release upload calls for the same tag can also race. Use a normalized value for the group key, e.g. release-${{ github.event.inputs.tag || github.ref_name }}, so both trigger types key off the bare tag name.

Key the concurrency group off the bare tag name for both trigger types so a tag-push and a workflow_dispatch backfill for the same tag serialize against each other.:

💡 Quality: github_release_exists return type annotated bool | None but never returns None

The docstring/type hint for github_release_exists in scripts/release/check_drift.py says it returns "True/False if the API answered, None if gh CLI itself is unavailable," but the implementation only ever returns True/False or raises UnreadableError (including when gh itself can't be invoked, per the except (OSError, subprocess.TimeoutExpired) branch). This is dead/misleading documentation that could confuse future maintainers reading main()'s if not released: check. Simplify the signature to -> bool and drop the None case from the docstring.

Correct the type hint and docstring to match actual behavior.:

def github_release_exists(tag: str) -> bool:
    """True/False if the GitHub API answered; raises UnreadableError otherwise
    (including when the gh CLI itself cannot be invoked).

💡 Edge Case: Tag-format validation regex is the sole guard against ref-injection across 3 jobs

The "Resolve target tag" step in verify validates $TAG against a strict semver-ish pattern and exit 1s on mismatch, which correctly halts the job and blocks publish/release (no if: always() overrides exist), so this is not currently exploitable. However, this regex is the only thing preventing an unvalidated tag string from reaching ref: refs/tags/${{ steps.resolve.outputs.tag }} in three separate checkout steps; if it's ever loosened or copy-pasted incorrectly elsewhere, ref-injection risk returns immediately across all three jobs. Consider centralizing the tag-format validation in one reusable script (mirroring assert_version.py) so the regex can't drift between the inline shell in verify and any future call sites.

🩺 Stability & Availability | 🔵 Trivial

Make scheduled drift failures produce an actionable notification.

The scheduled job runs check_drift.py, whose exit codes 1 and 2 fail the workflow. GitHub does not send failed scheduled-workflow email by default, so drift can remain visible only in Actions. Configure notifications for the responsible maintainer, or add an idempotent issue-alert job for schedule failures with job-level issues: write permission.

Handle pre-existing PyPI versions without PEP 740 provenance

When the exact version exists, pypi_version_exists.py skips the only publish step with attestations: true, while the workflow continues to create the GitHub Release. check_drift.py then reports drift for every PyPI file without urls[].provenance. PyPI does not support attaching PEP 740 attestations after upload, so the documented v2.1.0 backfill cannot close this gap. Add an explicit legacy-version policy, such as failing before release or exempting and documenting the version in check_drift.py; do not treat the backfill as complete.

Treat malformed PyPI JSON as unreadable input. If the decoded payload is not an object, or if a urls entry is not an object, these .get() calls raise AttributeError. main() does not catch it, so the script exits with status 1, which the workflow reserves for verified drift. Validate the payload and each entry, then raise UnreadableError so the script returns exit 2.

Read pyproject.toml in binary mode

Path.read_text() uses the process locale when no encoding is specified. A supported standalone invocation can run under a non-UTF-8 locale, causing valid UTF-8 TOML with non-ASCII text to raise UnicodeDecodeError before the existing handlers run. Use tomllib.load to make decoding locale-independent:

Ignore prerelease tags when selecting the latest release tag

Git’s default -v:refname ordering places v2.1.0-rc2 before v2.1.0. When both tags exist, latest_git_tag() can select the prerelease tag and cause the drift checks to fail.

Filter tags to final vX.Y.Z releases before selecting the first result.

Use the HTTP status line instead of gh stderr text.

gh api returns exit code 1 for every failed request. Its supported --include option writes the HTTP status line to stdout, while --silent only suppresses the response body. If gh changes its stderr wording, a reachable 404 can reach UnreadableError and return exit code 2 instead of reporting drift with exit code 1. Add --include --silent and parse the returned status code from stdout; return False only for status 404 and raise UnreadableError for other statuses or a missing status line.

Confidence score: 2/5

  • .github/workflows/release.yml can skip the only attestation-enabled PyPI upload when an existing version lacks PEP 740 provenance, while the release continues and may create a misleading GitHub Release; validate existing files and fail or explicitly handle legacy versions.
  • .github/workflows/release.yml uses inconsistent concurrency keys for tag pushes and manual backfills, allowing the same tag to publish concurrently and hit PyPI duplicate-file failures; normalize both triggers to the tag name.
  • scripts/release/check_drift.py can select prerelease tags as the latest release and can crash on valid-but-malformed PyPI JSON, producing false drift failures or an unhandled gate error; filter to final vX.Y.Z tags and validate the response shape before parsing.
  • The release checks in .github/workflows/release.yml, scripts/release/pypi_version_exists.py, and scripts/release/check_drift.py do not verify the built wheel in a fresh environment and lack focused coverage for critical success, drift, HTTP 404, and unreadable-input branches; add artifact-install/import checks and mocked tests before relying on these gates.

<file name="scripts/release/pypi_version_exists.py">

<violation number="1" location="scripts/release/pypi_version_exists.py:28">
P2: Custom agent: **Enforce Pragmatic Test Coverage**

The new PyPI publish gate has no tests for its critical branches. Add tests that mock `urlopen` and verify true for a valid response, false for HTTP 404, and exit 2 for other HTTP, timeout/network, malformed-JSON, and invalid-argument cases.</violation>

<violation number="2" location="scripts/release/pypi_version_exists.py:48">
P3: Connection-level failures (http.client.IncompleteRead, ConnectionResetError, other OSError subclasses) are not caught by this tuple, so a truncated/reset response escapes the handler and exits 1 with a raw traceback instead of the documented clean `UNREADABLE` message and exit 2. Broaden the tuple (e.g. add `OSError` and `http.client.HTTPException`, importing http.client) so every "PyPI could not be read" case keeps the fail-loud exit-2 contract the docstring promises.</violation>
</file>

<file name="scripts/release/check_drift.py">

<violation number="1" location="scripts/release/check_drift.py:14">
P3: The docstring claims the exit codes are 'checked by both workflows', but only `.github/workflows/release-drift.yml` invokes `check_drift.py`; `release.yml` does not reference it. This overstates the gate's reach and could mislead someone into thinking the release pipeline itself enforces drift checks.</violation>

<violation number="2" location="scripts/release/check_drift.py:74">
P2: When PyPI returns valid JSON with the wrong response shape, this parser raises `AttributeError` outside the `UnreadableError` handler. Validate the response object and each `urls[]` item before calling `.get()` so malformed registry data consistently returns exit 2.</violation>

<violation number="3" location="scripts/release/check_drift.py:85">
P3: Read `pyproject.toml` with `tomllib.load()` from a binary file handle. The current locale-dependent `read_text()` call can raise `UnicodeDecodeError` on valid UTF-8 TOML before the existing unreadable-input handlers run.</violation>

<violation number="4" location="scripts/release/check_drift.py:101">
P2: When a stable tag has a prerelease sibling, Git's `v:refname` ordering selects the prerelease first, so the daily gate reports drift even though the stable tag, `pyproject.toml`, and PyPI agree. Select the latest stable tag when present or implement prerelease-aware version ordering.</violation>

<violation number="5" location="scripts/release/check_drift.py:101">
P2: Filter tags to final `vX.Y.Z` releases before selecting the first sorted tag. Otherwise a prerelease such as `v2.1.0-rc2` can become the latest tag and cause false version, PyPI, and GitHub Release drift.</violation>

<violation number="6" location="scripts/release/check_drift.py:112">
P2: The gate picks the globally-highest `v*` tag as the canonical current version and compares it to `pyproject.toml` and PyPI. Because `release.yml` is tag-driven (pyproject is bumped on main before the release tag is pushed), every forward version bump immediately trips `tag_version != pv` and `pypi_v != tag_version`, so the standing gate goes red during the entire normal pre-release window — and any dangling/experimental higher `v*` tag anywhere in the repo trips it too. Repeated false drift alarms will teach operators to ignore the gate, undermining the fail-loud guarantee it exists to provide.</violation>

<violation number="7" location="scripts/release/check_drift.py:115">
P3: Change `github_release_exists` to return `bool` and document that unavailable or unexpected `gh` responses raise `UnreadableError`; the current `None` return case is impossible.</violation>

<violation number="8" location="scripts/release/check_drift.py:116">
P3: Custom agent: **Flag AI Slop and Fabricated Changes**

When `gh` is unavailable, `github_release_exists` raises `UnreadableError` rather than returning `None`, so this docstring advertises behavior the implementation never provides. Document the exception-based failure behavior (and align the `bool | None` annotation if this function remains internal).</violation>

<violation number="9" location="scripts/release/check_drift.py:128">
P2: Parse a machine-readable HTTP status from `gh api --include --silent` and treat only status 404 as a missing release. Matching stderr text can misclassify a reachable 404 as unreadable input.</violation>

<violation number="10" location="scripts/release/check_drift.py:133">
P2: Custom agent: **Enforce Pragmatic Test Coverage**

The new release gate has no tests for its main success, drift, or unreadable-source paths. Add focused tests that mock the git, PyPI, and GitHub sources and assert exit codes 0, 1, and 2, including missing releases and provenance.</violation>

P3: All three triggers share the concurrency group because each resolves `github.ref` to `refs/heads/main`, and `cancel-in-progress: true` cancels whichever run is in progress when a new one starts. A push or manual dispatch landing during the daily scheduled drift check silently cancels the scheduled audit instead of letting it finish. The drift state is still covered because the push also runs the same check, but the scheduled-run failure notification (the only explicit alerting this job produces) can be suppressed. Use a group that distinguishes the triggers, or set `cancel-in-progress: false`, so the daily audit always completes.</violation>

The new PyPI publish gate has no tests for its critical branches. Add tests that mock urlopen and verify true for a valid response, false for HTTP 404, and exit 2 for other HTTP, timeout/network, malformed-JSON, and invalid-argument cases.

P3: Connection-level failures (http.client.IncompleteRead, ConnectionResetError, other OSError subclasses) are not caught by this tuple, so a truncated/reset response escapes the handler and exits 1 with a raw traceback instead of the documented clean UNREADABLE message and exit 2. Broaden the tuple (e.g. add OSError and http.client.HTTPException, importing http.client) so every "PyPI could not be read" case keeps the fail-loud exit-2 contract the docstring promises.

P3: All three triggers share the concurrency group because each resolves github.ref to refs/heads/main, and cancel-in-progress: true cancels whichever run is in progress when a new one starts. A push or manual dispatch landing during the daily scheduled drift check silently cancels the scheduled audit instead of letting it finish. The drift state is still covered because the push also runs the same check, but the scheduled-run failure notification (the only explicit alerting this job produces) can be suppressed. Use a group that distinguishes the triggers, or set cancel-in-progress: false, so the daily audit always completes.

…#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.
