LOCAL_EMBEDDING_MODEL_FILE	—	—	ONNX file path inside a manifest-backed local embedding directory
LOCAL_EMBEDDING_POOLING	—	—	Explicit pooling for an external local embedding ID without a manifest
LOCAL_EMBEDDING_NORMALIZE	—	—	Explicit L2 normalization for an external local embedding ID without a manifest
