name: tests

# Reusable race-test matrix for the state-machine modules. Runs `go test -race
# ./...` for each module across the Go × OS matrix. Called by ci.yml so the legs
# render as a single collapsible tree in the checks UI (e.g. "state machine tests
# / test (1.25.11, ubuntu-latest)") instead of cluttering the top-level checks
# list. The sink-domain modules have their own reusable workflow (sink.yml).
