WalkthroughThe documentation workflow now uses ChangesDocumentation preview deployment
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The deployment workflow may publish a preview under the wrong pull request when a commit matches multiple pull requests, which could expose documentation artifacts in the wrong review context. Merge should wait until ambiguous pull-request lookups fail safely. Sequence Diagram(s)sequenceDiagram

github.event.workflow_run.conclusion to equal 'success' before deployment,
replacing the current check that only excludes 'cancelled'; preserve the
pull_request event filter.
- Around line 24-32: Remove the pr-number artifact download and Set PR number
steps; derive GH_PR_NUM from the workflow_run event metadata, using its
pull_requests value and a head_sha API lookup fallback when that list is empty,
then validate the resolved pull request number from the trusted API response
before exporting it.

I don't know a lot about this. the CodeRabbit stuff sounds like things we want to fix. I also have a question about whether we need always() and !cancelled().
| - name: Upload documentation | ||
| if: always() | ||
| - name: Upload documentation preview | ||
| if: always() && !cancelled() && github.event_name != 'pull_request' |

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

@dlabaj The coderabbit callouts seem like they're worth investigating. Maybe we can limit the surge deployments to just PF team member /deploy-preview comments, if it ends up being tricky to safely pass PR for the workflow? |

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].

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.
