where JIT code lives.** Open it after the include block and close it at the end of the file, with the device kernels, traits and host wrapper inside. The shared `host::` / `device::` helpers are nested in it too, so they resolve unqualified. `load_jit` emits the `TVM_FFI_DLL_EXPORT_TYPED_FUNC` wrapper inside `namespace sglang` as well, so the `kernel_name` you pass from Python needs no `sglang::` prefix. - **Check where the check is cheapest: `static_assert` > C++ host check > cached Python > per-call Python.** Anything fixed at compile time is a `static_assert`. Anything about the tensors is a `TensorMatcher` / `CHECK_HOST` in the C++ launcher, free next to a kernel launch. A check Python cannot delegate goes inside the `@cache_once` module factory, where it runs once per specialisation. What remains in the per-call entry point costs interpreter time on *every* forward, so it should be nothing but picking the module and allocating `out`. - **Fixed-width integer types.** Prefer `int32_t` / `int64_t` / `uint32_t` / `size_t` over `int`, `long`, or `long long`, so an index has the same width on both sides of the FFI boundary. Bare `int` is fine only where the width plainly cannot matter — an unrolled loop counter over a `constexpr` bound, a template `int` parameter. Shapes arrive as `int64_t` (`SymbolicSize::unwrap()`); narrowing to `uint32_t` for in-kernel indexing is a deliberate act, so write the `static_cast` explicitly and only where the range is known. - **Doxygen comments in C++.** Document exported entities with `///` or `/** ... */` blocks using `\brief`, `\param`, `\tparam`, `\return`, the way `include/sgl_kernel/` does. `python -m sglang.kernels.jit` writes `CommentFormat: Doxygen` into `.clangd` when clangd is 21 or newer, so these render on hover in the editor.
