+## Release process
+
+- The tagged source commit must already contain the package version it
+  releases. Do not make the release workflow edit `pyproject.toml`.
+- The tag must be `vMAJOR.MINOR.PATCH`, and `.github/workflows/release.yml`
+  verifies that it matches `project.version` before building GitHub release
+  assets and publishing to PyPI.
+- Prepare releases on a branch from current `main`. Set `VERSION`, then run:
+
+```sh
+set -euo pipefail
+
+VERSION=0.1.1
+BRANCH="release-v${VERSION}"
+
+git fetch origin --tags --prune
+git switch main
+git pull --ff-only
+git switch -c "${BRANCH}"
+
+uv run python - "${VERSION}" <<'PY'
+from pathlib import Path
+import re
+import sys
+
+version = sys.argv[1]
+path = Path("pyproject.toml")
+text = path.read_text()
+new_text = re.sub(
+    r'(?m)^version = "[^"]+"$',
+    f'version = "{version}"',
+    text,
+    count=1,
+)
+if new_text == text:
+    raise SystemExit("pyproject.toml version was not updated")
+path.write_text(new_text)
+PY
+
+uv lock
+```
+
+- Validate before opening the PR:
+
+```sh
+set -euo pipefail
+
+uv lock --check
+npx --yes markdownlint-cli2
+uv run ruff check .
+uv run ruff format --check .
+uv run pyright
+uv run python -m unittest discover -s tests
+uv build --wheel --sdist --out-dir /tmp/src-py-lib-release-check --no-create-gitignore
+rm -rf /tmp/src-py-lib-release-check
+```
+
+- Commit, push, open the PR, wait for checks, then merge it. If review is
+  required, stop after `gh pr checks` and ask for review before merging.
+
+```sh
+set -euo pipefail
+
+VERSION=0.1.1
+BRANCH="release-v${VERSION}"
+GH_REPO="sourcegraph/src-py-lib"
+
+git add pyproject.toml uv.lock
+git commit -m "Release v${VERSION}"
+git push -u origin "${BRANCH}"
+
+gh pr create \
+  --repo "${GH_REPO}" \
+  --base main \
+  --head "${BRANCH}" \
+  --title "Release v${VERSION}" \
+  --body "Bump src-py-lib package metadata to ${VERSION}."
+
+gh pr checks "${BRANCH}" --repo "${GH_REPO}" --watch --fail-fast
+gh pr merge "${BRANCH}" --repo "${GH_REPO}" --squash --delete-branch
+```
+
+- Tag the merged `main` commit. Do not tag a branch commit.
+
+```sh
+set -euo pipefail
+
+VERSION=0.1.1
+
+git fetch origin --tags --prune
+git switch main
+git pull --ff-only
+git tag "v${VERSION}"
+git push origin "v${VERSION}"
+```
+
+- Watch the release workflow and confirm the GitHub release and PyPI project.
+
+```sh
+set -euo pipefail
+
+VERSION=0.1.1
+GH_REPO="sourcegraph/src-py-lib"
+
+RUN_ID="$(
+  gh run list \
+    --repo "${GH_REPO}" \
+    --workflow release.yml \
+    --branch "v${VERSION}" \
+    --limit 1 \
+    --json databaseId \
+    --jq '.[0].databaseId // empty'
+)"
+test -n "${RUN_ID}"
+gh run watch "${RUN_ID}" --repo "${GH_REPO}" --exit-status
+gh release view "v${VERSION}" --repo "${GH_REPO}"
+uvx --from pip pip index versions src-py-lib
+```
+
+- If a pushed tag points at the wrong commit, move it only after explicit
+  human approval.
