# Platform Notes

> NumKong for C++

### Integration Notes

- The C ABI is the easiest place to integrate with foreign runtimes and custom allocators.
- The C++ layer is the easiest place to express typed packed workflows, tensor slicing, and allocator-aware ownership.
- `aligned_allocator` defaults to 64-byte alignment for owned containers, but unaligned caller inputs are still valid for the kernels that accept raw pointers or views.
- If you override result types away from the scalar defaults, document that choice carefully because it can change both performance and numerical policy.
