Input

• PR: <pr-number>

Do (end-to-end) Goal: PR ends in GitHub state MERGED (never CLOSED). Use gh pr merge with --rebase or --squash.

1. Repo clean: git status.
2. Identify PR meta (author + head branch):
   • gh pr view <pr-number> --json number,title,author,headRefName,baseRefName --jq '{number,title,author:.author.login,head:.headRefName,base:.baseRefName}'
   • contrib=$(gh pr view <pr-number> --json author --jq .author.login)
   • head=$(gh pr view <pr-number> --json headRefName --jq .headRefName)
3. Fast-forward base:
   • git checkout main
   • git pull --ff-only
4. Create temp base branch from main:
   • git checkout -b temp/landpr-<pr-number>
5. Check out PR branch locally:
   • gh pr checkout <pr-number>
6. Rebase PR branch onto temp base:
   • git rebase temp/landpr-<pr-number>
   • fix conflicts; keep history tidy
7. Fix + tests + changelog:
   • implement fixes + add/adjust tests
   • update CHANGELOG.md and mention #<pr-number> + @$contrib
8. Pick merge strategy (if unclear, ask):
   • Rebase: preserve commit history
   • Squash: single clean commit
9. Full gate (BEFORE commit):
   • pnpm lint && pnpm build && pnpm test
10. Commit via committer (include #<pr-number> + contributor in commit message):

• committer "fix: <summary> (#<pr-number>) (thanks @$contrib)" CHANGELOG.md <changed files>
• capture land_sha=$(git rev-parse HEAD)

11. Push updated PR branch (rebase => usually needs force):

• git push --force-with-lease

12. Merge PR (must show MERGED on GitHub):

• Rebase: gh pr merge <pr-number> --rebase
• Squash: gh pr merge <pr-number> --squash
• Never gh pr close

13. Sync main + push:

• git checkout main
• git pull --ff-only
• git push

14. Comment on PR with what we did + SHAs + thanks:

• merge_sha=$(gh pr view <pr-number> --json mergeCommit --jq '.mergeCommit.oid')
• gh pr comment <pr-number> --body "Landed via temp rebase onto main.\n\n- Gate: pnpm lint && pnpm build && pnpm test\n- Land commit: $land_sha\n- Merge commit: $merge_sha\n\nThanks @$contrib!"

15. Verify PR state == MERGED:

• gh pr view <pr-number> --json state,mergedAt --jq '.state + \" @ \" + .mergedAt'

16. Delete temp branch:

• git branch -D temp/landpr-<pr-number>
