    note: Route table read from the FastAPI APIRouter prefixes in main.py (openai_v1_router, megatron_router '/megatron', health_router '/health' and generate_router '/generate' are all mounted under '/v1'; slurm_router '/slurm' is mounted at the app root). Schemas transcribed from the Pydantic models under routers/request_types/. CompletionRequest and ChatCompletionRequest are vLLM types re-exported by ScalarLM and are modelled as open objects rather than reproduced field by field.
