GitHub REST API list pull requests associated with a commit can return multiple pull requests endpoint documentation

💡 Result:

Yes, the GitHub REST API endpoint GET /repos/{owner}/{repo}/commits/{commit_sha}/pulls can return multiple pull requests [1][2]. According to the official GitHub documentation, the behavior of this endpoint is as follows: 1. It lists the merged pull request that introduced the commit to the repository [1][2]. 2. If the commit is not present in the default branch, the endpoint will return both merged and open pull requests associated with the commit [1][2]. Because it returns an array of pull request objects, it is possible for the response to contain multiple items depending on the state of the commit and the associated pull requests [1][3]. Additionally, you can pass a branch name as the commit_sha parameter to list open or merged pull requests associated with that branch [1][2].

Citations:

Reject ambiguous pull-request lookups.

When workflow metadata has no pull request, line 34 selects the first result from an endpoint that can return multiple pull requests for one commit. Resolve the fallback only when exactly one pull request matches the source run; otherwise fail the deployment. This prevents publishing artifacts under another pull request's preview URL or comment.

Do we need both the always() and !cancelled() calls? I am not an expert on this, but it sounds like maybe we don't: https://docs.github.com/en/actions/reference/workflows-and-actions/expressions#always
