+"""
+AOT-Inductor compile the exported SAM3 full pipeline ``.pt2``.
+
+Loads an ExportedProgram saved by ``scripts/export_sam3_full_pipeline.py``
+and packages it into an AOTI ``.pt2`` runner that can be loaded with
+``torch._inductor.aoti_load_package``.
+
+Usage::
+
+    python scripts/compile_sam3_aoti.py \
+        --in artifacts/export/full_sam3_pipeline.pt2 \
+        --out artifacts/aoti/full_sam3_pipeline_aoti.pt2
+
+Environment requirements (CUDA build):
+- ``CUDA_HOME`` must point at a CUDA toolkit with ``nvcc``. If the system
+  doesn't have one installed, the simplest path is::
+
+      uv pip install --index-url https://pypi.nvidia.com \\
+          nvidia-cuda-nvcc nvidia-cuda-cccl
+      export CUDA_HOME=$VIRTUAL_ENV/lib/python3.12/site-packages/nvidia/cu13
+      export PATH=$CUDA_HOME/bin:$PATH
+
+  The torch wheels (``torch==2.10.0+cu128``) do not bundle ``nvcc`` —
+  only the runtime libraries.
+- ``import torchvision.ops`` runs before ``torch.export.load`` so that
+  ``torch.ops.torchvision.roi_align.default`` is registered before the
+  serialized graph references it.
