The issue provides a ranked table of 50 packages and identifies 11 packages lacking both upstream riscv64 wheels and RISE registry entries. It names no files, tests, commands, or build entry point, so first locate the repository workflow for building Python wheels; done means the targeted packages have riscv64 wheels and the table's registry status is updated.
