## Summary of Changes Hello @junrushao, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces extensive documentation for TVM-FFI's tensor handling, centralizing around the DLPack standard. It aims to provide clear guidance on tensor types, ownership, memory layouts, and ABI conversions, along with practical API usage and integration strategies for various developer roles, ensuring a consistent and robust approach to tensor management within the TVM-FFI ecosystem. ### Highlights * **New Tensor Documentation**: A comprehensive guide `docs/concepts/tensor.rst` has been added, detailing how TVM-FFI handles tensors, with a strong focus on DLPack integration. * **Tensor Types and Ownership**: The documentation clarifies different tensor types (DLPack's `DLTensor`, `DLManagedTensorVersioned`, and TVM-FFI's `TensorView`, `TensorObj`, `Tensor`) and their ownership semantics (non-owning views vs. managed objects). * **ABI Layout and Conversion**: It explains the memory layout of these tensor types and how conversions occur across TVM-FFI's stable C ABI, emphasizing lifetime management. * **API Usage and Allocation**: The guide covers important C++ and Python APIs for tensor manipulation, recommended allocation patterns (e.g., `FromEnvAlloc`), and what TVM-FFI's tensor system *does not* provide (e.g., kernels, advanced indexing). * **Integration Guidance**: Specific tips are provided for kernel library developers, graph compilers, and runtimes on how to effectively integrate with TVM-FFI's tensor system, including stream context for GPU. * **Documentation Structure Update**: The main documentation index (`docs/index.rst`) has been updated to include the new tensor concept document. * **Minor Code Comment**: A small comment was added in `include/tvm/ffi/reflection/overload.h` for clarity regarding a super class alias. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. **Click [here](https://codeassist.google/code-review/login) to enable Memory in your admin console.** <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
