| # Merge-commit PR variant of ../sdk-repo's stlc-promote.yml, for when the | |
| # production repo requires a PR for changes to main. On push to staging main | |
| # (and manual dispatch) it pushes staging main to a stainless/release branch on | |
| # production, opens a PR into production main, and enables auto-merge. That PR | |
| # MUST merge with a MERGE COMMIT — never squash/rebase, or the SHAs get rewritten | |
| # and the trunks fork. Self-routed to staging; needs PRODUCTION_REPO_TOKEN with Contents + Pull requests: write on production. | |
