yggdrasil-engine is Unleash's ctypes binding to their yggdrasilffi Rust cdylib (github.com/Unleash/yggdrasil-bindings), not Google's Yggdrasil Decision Forests despite the name. Upstream downloads a prebuilt binary per platform instead of compiling it, and ships none for riscv64, so this workflow builds the cdylib natively in the manylinux_2_39_riscv64 container, runs upstream's own pytest suite against it, and retags the resulting wheel with upstream's own repair_wheel.py. compat_glibc.rs's hand-rolled gettid/statx syscall shim only defines its syscall numbers for x86_64 and aarch64 but compiles unconditionally, so the crate fails to build on riscv64 with two cannot-find-value errors; the added patch supplies the same numbers for riscv64, which uses the identical generic syscall table as aarch64.
