# Verify the OpenZaak → Open Notificaties (NRC) notification path end to end (S-01-c,
# #56): a zaak created in OpenZaak is published to NRC and delivered to a subscriber.
#
# Everything that talks to OpenZaak/NRC runs *inside* the compose network and reaches
# them by container IP — the hosted CI runner can't reach published ports (sibling
# containers, gitea-actions-gotchas.md §5) and OpenZaak/NRC reject a single-label host
# in URLs (Django URLValidator). Plain docker primitives only (docker/podman-portable),
# like infra/seed-config.sh and infra/run-integration.sh. See ADR-0007.
