Thank you for your feedback regarding the lldb failure. After [discussions](https://github.com/llvm/llvm-project/issues/137046#issuecomment-2895504831) with @dmpots, we identified that the issue stems from an implicit dependency on `<__ranges/movable_box.h>` in lldb’s tests, likely due to clang’s AST processing. This patch itself does not introduce issues to libc++. I’ve submitted a temporary fix in #140960 by re-adding the header. However, a long-term solution may require deeper investigation by the lldb or clang teams, and I’d welcome their input on this.
