| name: OBS Stale PR Cleanup | |
| # Runs daily. For each open PR, looks at the last commit's date and: | |
| # - skips PRs carrying the `keep-pr-build` label (never delete); | |
| # - posts a one-day deletion warning when the last commit is >= WARN_DAYS old | |
| # (idempotent: a marker in the comment body avoids reposting); | |
| # - deletes the PR's OBS project when the last commit is >= DELETE_DAYS old. | |
| # Staleness is measured from the last commit (not updatedAt) so that posting | |
| # the warning comment does not reset the deletion countdown. | |
| # Can also be triggered manually via workflow_dispatch. | |
