Pull Request

Purpose

Automate PR creation when version branches are created via version_branch.yml workflow to eliminate manual steps and ensure consistent review process.

Change Summary

Modified .github/workflows/version_branch.yml:

Added permission: pull-requests: write to workflow
Added step: "Create pull request" after branch push
- Creates PR from version branch to base branch
- Title format: Version branch {VERSION} or Version branch {VERSION} ({VERSION_TEXT})
- Body includes: version, version text, branch prefix, base branch
- Uses gh pr create with captured output and exit codes
- Workflow continues on PR creation failure (handles duplicate PRs, no-commit scenarios)

Example workflow execution:

# Input: new_version="03.05.00", version_text="RC1", branch_prefix="dev/"
# Creates branch: dev/03.05.00
# Auto-creates PR: "Version branch 03.05.00 (RC1)" targeting base branch

Pattern follows existing release_pipeline.yml PR creation implementation.

Testing Evidence

YAML validation: passed (all 6 workflows)
CodeQL scan: 0 alerts
No tabs/control characters
Workflow validation script: passed

Risk and Rollback

Risk: Low. Step only creates PR; does not modify branch or files.

Failure modes handled:

PR already exists → logs info, continues
No commits between branches → logs info, continues
Other errors → logs warning, continues

Rollback: Revert commit or disable step via REPORT_ONLY=true flag.

Checklist

Reviewer Notes

Error handling uses regex patterns pull request.*already exists and no commits between.*branch to avoid false positives. Step skipped when REPORT_ONLY=true to preserve dry-run behavior.

The grep pattern on line 676 may not match the actual GitHub CLI error message for the "no commits" scenario. The expected message format is typically "no commits between BASE and HEAD", which may not contain the word "branch". Consider adjusting the pattern to "no commits between" without requiring "branch" in the match, or test the actual error message format to ensure the pattern matches correctly.

            elif echo "${PR_OUTPUT}" | grep -iqE "no commits between"; then
