name: 'Distributed E2E Tests'

# The distributed architecture against real PostgreSQL and NATS (including the
# NATS JWT specs), started by testcontainers, plus the multi-frontend paths
# against the in-process bus under the race detector. Nothing else runs the
# dedicated `make test-e2e-distributed` target: `make test-e2e` reaches these
# specs only because it recurses, and only after it has built the e2e image.
