+summary: >
+  Add the SEA route-construction contract and node_model_routing_compute (Phase 0 + Phase 1 of the SEA
+  node-ization plan, epic OMN-12468). The routing contract owns route construction only: the local-first
+  model ladder with cloud_opt_in=false, the three verbatim prompt blocks (node_generator_v1 with sandbox
+  lines, node_generator_eval_v1 without them, self_extending_agent_v1), and generation params (max_tokens=2048
+  moved out of consumer.py and eval_runner.py). The YAML loader rejects unknown keys; route resolution
+  fails closed (ROUTE_NOT_FOUND, CLOUD_NOT_OPTED_IN) with no silent downgrade.
