## Summary - Extend `@py_class` to detect and register recognized FFI dunder methods (`__ffi_repr__`, `__ffi_eq__`, `__s_equal__`, etc.) defined on Python dataclasses, making them callable from C++ and other FFI languages - `_FFI_RECOGNIZED_METHODS` allowlist in `py_class.py` gates which dunders are collected; `_collect_py_methods()` scans class dict and `TypeInfo._register_py_methods()` registers via the C API (`TVMFFITypeRegisterMethod` + `TVMFFITypeRegisterAttr`) - No C++ changes — `dataclass.cc` is unmodified from upstream ## Test plan - [x] 12 new dedicated tests covering allowlist filtering, registration, round-trip dispatch (repr, eq, compare, hash) - [x] All 590 existing tests in affected test files pass (`test_dataclass_py_class`, `test_dataclass_repr`, `test_dataclass_compare`, `test_dataclass_hash`) - [ ] CI: lint, C++ tests, Python tests, Rust tests 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
