- [x] works on Linux (ie CI)
- [x] works on Mac (ie my computer)

[First CI
run](https://github.com/temporalio/temporal/actions/runs/12269035797/attempts/1?pr=6966),
`TestNexusCallbackReplicated` failed with `Error while dialing: dial tcp
127.0.0.1:33279: connect: connection refused`. Looks like there was an
unrelated data race (that I've reported to Slack).

[Second CI
run](https://github.com/temporalio/temporal/actions/runs/12269035797/attempts/2?pr=6966)
passed.

[Third CI
run](https://github.com/temporalio/temporal/actions/runs/12269035797?pr=6966),
Versioning suite seems to have [timed
out](https://github.com/temporalio/temporal/actions/runs/12269035797/job/34233452135?pr=6966#step:8:966).
Unrelated.

So it seems to be fine from a random port perspective.

## Potential risks

change to production? -->

stated in `docs/`? If significant

be sent to the broader community? (Yes/No) -->
