 # Wraps run_platform.sh for L2 composition modules in the modules-lifecycle
 # pipeline. Sets ACDL_REMOTE_STATE_KEY to point to the CI VPC state.
 #
+# NOTE: unlike the L1 scripts (run_lifecycle_destroy.sh), the L2 path does
+# NOT take a ci-vpc-outputs.json argument. L2 compositions reference the
+# platform VPC via terraform_remote_state (a data source), not by injecting
+# VPC outputs into the contract. The workflow passes 2 positional args for
+# parity with the L1 matrix, but $2 is accepted-but-ignored here (documented,
+# not a bug).
+#
 # Lifecycle mode (REQ-134): ACDL_LIFECYCLE_MODE default "plan" = no-op
 # (plan mode never applies resources, so there is nothing to destroy).
 # Set to "full" for the real `--destroy` against live AWS.
