+## Ejemplo
+
+```bash
+source bash/functions/infra/cuda_toolkit_check.sh
+cuda_toolkit_check
+```
+
+Salida en maquina con CUDA completo:
+```
+nvcc=12.4
+nvidia_smi=present
+driver_version=550.54.15
+cuda_libs=/usr/local/cuda
+overall=ok
+```
+
+Salida en maquina sin CUDA:
+```
+nvcc=missing
+nvidia_smi=missing
+driver_version=missing
+cuda_libs=missing
+overall=missing
+```
+
+Invocar directamente:
+```bash
+bash bash/functions/infra/cuda_toolkit_check.sh
+```
+
+Parsear desde otro script:
+```bash
+eval "$(cuda_toolkit_check)"
+echo "CUDA overall: $overall"
+if [[ "$overall" == "ok" ]]; then
+    echo "CUDA completo: nvcc=$nvcc driver=$driver_version libs=$cuda_libs"
+fi
+```
+
+## Notas
+
+- Idempotente: no instala, no modifica nada, solo consulta.
+- Exit code 0 siempre — ausencia de CUDA es informacion, no fallo.
+- Busca `libcuda.so` en `/usr/local/cuda*`, `/opt/cuda*` y via `ldconfig -p`.
+- `driver_version` refleja el driver NVIDIA del kernel, reportado por nvidia-smi.
+- `nvcc` reporta la version del compilador CUDA toolkit (puede diferir de la version soportada por el driver).
+- Para obtener la version CUDA maxima soportada por el driver, usar `get_gpu_info_go_infra` (campo CudaVersion del struct GpuInfo).
