# L1 asserts ServiceDefinition -> rendered resources match golden expectations
# (e.g. `egress: vpn` renders the kill-switched egress path). The actual render
# + assert is Chainsaw's L1 layer, owned by the conformance harness (T-0.4).
# CI just invokes the runner filtered to the L1 layer and the touched subset.
