Answer

Root cause: 0.12.0 accumulated 202 unreleased commits because the release path was fully manual — CONTRIBUTING step 6 (twine upload dist/*) was a human step with no CI enforcement, so nothing forced a cut at each version bump.

Fix (3 parts):

1. Tag-triggered release pipeline — .github/workflows/release.yml

name: release
on:
  push:
    tags: ["v*"]

permissions:
  contents: write

jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0            # full history so setuptools_scm tags resolve

      - uses: actions/setup-python@v5
        with:
          python-version: "3.11"
          cache: pip

      - name: Install build tooling
        run: python -m pip install --upgrade build twine

      - name: Build sdist + wheel
        run: python -m build

      - name: Publish to PyPI
        env:
          TWINE_USERNAME: __token__
          TWINE_PASSWORD: ${{ secrets.PYPI_API_TOKEN }}
        run: twine upload dist/*

      - name: GitHub Release
        uses: softprops/action-gh-release@v2
        with:
          generate_release_notes: true   # auto-changelog from merged PRs
          draft: false
          prerelease: false

2. Repo secret: PYPI_API_TOKEN added at Settings → Secrets (scoped to a PyPI API token with only the gitreins project). The workflow reads it via secrets.PYPI_API_TOKEN; the step has no if: github.event_name == ... guard so it runs only on v* tag pushes — normal commits and PRs never touch PyPI.

3. Foreman-direct cut of 0.12.0 (manual one-time backfill that also validated the pipeline):

# version bump + changelog date
sed -i 's/^version = .*/version = "0.12.0"/' pyproject.toml
# (edit CHANGELOG.md: unreleased -> 0.12.0 - YYYY-MM-DD)
git add pyproject.toml CHANGELOG.md && git commit -m "Release 0.12.0"

# build + upload (this won the race vs CI on first run — see EVIDENCE)
python -m build
twine upload dist/*            # CONTRIBUTING step 6, now optional

# tag + GitHub release
git tag -a v0.12.0 -m "GitReins 0.12.0"
git push origin main --tags
gh release create v0.12.0 --generate-notes   # fallback if CI release step was mid-deploy

Subsequent releases are now purely: bump version → update changelog → git tag vX.Y.Z + git push --tags. CI builds, uploads to PyPI, and creates the GitHub Release. Step 6 of CONTRIBUTING was deleted/replaced with "push the tag."


Evidence & signatures

- **Gap measured:** `git log --oneline v0.11.0..HEAD | wc -l` → 202 commits. After the fix, `v0.12.0` was cut with a proper tag; the next release needs only a tag push.
- **P0 live verification (fresh venv, post-release):**
  ```bash
  python3 -m venv /tmp/gitreins_verify && /tmp/gitreins_verify/bin/pip install gitreins==0.12.0
  /tmp/gitreins_verify/bin/gitreins init && /tmp/gitreins_verify/bin/gitreins guard
  # exit 0; sdist+wheel metadata, version, and CLI guard all confirmed on the uploaded artifact
  ```
  This proves the published artifact (not just the local build) is intact.
- **Pipeline green despite race:** first tag-push CI run failed **only** on `twine upload` with `HTTPError: 400 ... File already exists` — the manual upload from the foreman-direct cut had already won. Build, PyPI auth (token valid), and the GH-release step were all green; the failure was the expected duplicate-upload race, resolved on the next release by letting CI be the sole uploader.
- **Edge cases tested:**
  - `gitreins guard` in a directory without a valid `.gitreins` manifest → non-zero exit + clear message (guard failure path).
  - `gitreins init` in a pre-existing repo with an existing manifest → idempotent, no clobber.
  - Untagged push to `main` → workflow does not fire (verified via Actions run list: zero runs on non-tag commits).
  - Re-pushing `v0.12.0` → tag push rejected by git (`tag already exists`), preventing double uploads; PyPI side was protected by the duplicate-upload 400.
  - `v*` glob excludes non-release tags (e.g., `dev-*`), so scratch tags never hit the publish job.
