Transient failures in actions/download-artifact are a frequent source of flaky CI runs. Add a retry step after each download that triggers only when the first attempt fails (continue-on-error + outcome check). Applied to both functional-tests.yaml and upgrade-tests.yaml.

There was a problem hiding this comment.
It would be nice if the task itself could have retries, but this "maybe just run it again" will help.

Agreed - that feature isn't built in to github actions though, it would require referencing a third party action. |

Transient failures in
actions/download-artifactare a frequent source of flaky CI runs — I see these several times a week, always succeeding on manual re-run.This adds a single automatic retry for each
download-artifactstep using thecontinue-on-error+outcome == 'failure'pattern:How it works: Each download step gets
id+continue-on-error: true. A duplicate step follows that only runs when the first attempt failed (steps.<id>.outcome == 'failure'). No new dependencies, no third-party actions.Example of a recent failure this would fix: https://github.com/microsoft/VFSForGit/actions/runs/26310137269/job/77463758324?pr=1981
