Looks like this is the offending commit.

The logs for the set-status job look like this:

2023-04-25 17:53.03: New job: Set ocaml/opam refs/heads/master
                     e66648f0/ocaml-benchmarks to
                     {"state":"pending","target_url":"https://autumn.ocamllabs.io/ocaml/opam"}

                       {
                         "context": "ocaml-benchmarks",
                         "state": "pending",
                         "target_url": "https://autumn.ocamllabs.io/ocaml/opam"
                       }
2023-04-25 17:53.08: Job succeeded

I've looked at the code, and tried to look at the API docs and it doesn't seem like something like this would "delete" other statuses.

The same thing happened for already opened PRs on ocaml/opam

Okay, thanks for the additional information.
