  "_note": "kb#128 (A2A-16): human-readable source of truth for the auto_router route set. NOT loaded from this path at runtime -- litellm-config.yaml's `auto_router` deployment inlines this same `routes` array as a literal JSON string via litellm_params.auto_router_config. Reason (verified hands-on 2026-07-26 against litellm:main-latest): the auto_router_config_path loader (AutoRouter._load_semantic_routing_routes -> SemanticRouter.from_json) unconditionally builds a raw semantic_router encoder from encoder_type/encoder_name and requires a real provider API key even for a local model name like bge-m3 -- this IS the open Auto Router v2 embedding bug the task brief warned about. The auto_router_config (inline-string) loader (_load_auto_router_routes_from_config_json) only reads the `routes` key and builds Route objects directly, with zero encoder bootstrap -- confirmed working end-to-end: real litellm.embedding(model=ollama/bge-m3) calls, zero metered API spend, 'hi there' -> ollama/gemma3:4b, a refactor/dependency-injection prompt -> kimi-agent. Keep the two `routes` arrays in sync by hand when editing either.",
