Create Release

Create a CRAN release

Use the repository's two-stage workflow: submit from an open release branch, then publish the GitHub Release from main only after CRAN acceptance.

Establish the release target

1. Read AGENTS.md and .github/workflows/submit-cran.yaml.
2. Verify GitHub authentication, fetch origin, and preserve unrelated local changes. Use a clean worktree when needed.
3. Query CRAN for the latest version actually published. Cross-check it against DESCRIPTION, open release pull requests, and GitHub tags and releases.
4. If resuming an existing release branch, pull request, or rejected submission, keep its target version. Do not increment past it or create a duplicate.
5. When starting a new release and the user has not specified the release type, ask whether it is patch, minor, or major. Compute the new version from the CRAN-published version, not from an unaccepted submission.
6. Start a new release-x.y.z branch from the latest origin/main only when no matching release is already in flight.

Prepare and validate

1. Review commits and merged pull requests since the latest CRAN release and the existing development section in NEWS.md. Do not invent changes.

2. Synchronize the target version in DESCRIPTION, the first NEWS.md heading, and codemeta.json; remove any development .9000 suffix.

3. Keep NEWS concise and user-facing. Omit routine dependency, lint, formatting, CI, and generated-file maintenance.

4. Update cran-comments.md accurately. Mention a CRAN issue only when the repository evidence supports it.

5. Do not refresh dependencies merely because this is a release.

6. Run the complete release gate:

   air format . --check
   make lint
   make hooks
   make check
   git diff --check
   

7. Clean build artifacts, inspect the complete diff, commit the validated release state, and push the release branch. Only then open or update a ready-for-review pull request against main; its title must contain the exact text CRAN Release and its body must describe the final net diff and validation.

8. Wait for every required check to pass. Address, reply to, and resolve every actionable review thread. After each fix, rerun the affected validation, commit and push it, and re-fetch the live thread and check state.

Submit while the pull request stays open

1. Keep the CRAN Release pull request open. Verify that the worktree is clean and the remote release-branch SHA matches the validated local HEAD, then dispatch the package workflow from that branch:

   gh workflow run submit-cran.yaml --ref release-x.y.z
   

2. Find and watch the resulting run. On a non-default branch, the reusable workflow must build and submit to CRAN while the GitHub Release job is skipped. Inspect the logs and verify that no tag or GitHub Release was created. Record the workflow run's head SHA as the exact submitted commit.

3. If submission fails, fix it on the same release branch and retry only after the updated pull request checks are green.

4. When submission succeeds, report the exact version and workflow run, remind the maintainer to confirm the CRAN email, and stop. Submission success and email confirmation are not CRAN acceptance.

5. Never merge the pull request, create a tag, or create a GitHub Release until the user explicitly states that CRAN accepted the package.

Publish only after CRAN acceptance

1. After the user explicitly reports acceptance, verify that CRAN publishes the target version.
2. Squash-merge the CRAN Release pull request and verify that main contains the accepted version.
3. Dispatch submit-cran.yaml from main and watch it to completion. On the default branch, the reusable workflow must skip CRAN submission, resolve the most recently merged matching CRAN Release <version> pull request, and rebuild and publish from that pull request's original submitted head SHA.
4. Verify that the tag targets the recorded submitted SHA, not a later main tree; the source tarball is attached; and the release body is the complete matching NEWS.md version section verbatim. Never use generated release notes or summarize NEWS.
