# Wrangler-style InteractionTopology fragment for this lab.
#
# In Phase 7 vocabulary this is an InteractionTopology description: it names
# one Channel ("greeting") and two Picos ("hello-producer-pico" publishes,
# "hello-consumer-pico" subscribes). The "wiring" list makes the runtime
# relationship between the two Picos explicit: producer -> channel -> consumer.
#
# It is authored as an ordinary YAML fragment adjacent to the lab, not a new
# platform format. It is applied to the cluster as a ConfigMap
# (04-topology-configmap.yaml) so the RuntimeEnvironment can carry the same
# declarative truth as the walkthrough.
