+# Based on upstream's own release pipeline:
+#   https://github.com/opendp/opendp/blob/v0.16.0/.github/workflows/.build.yml
+# opendp is a Rust library exposed to Python as a plain cdylib (setuptools-rust,
+# binding=NoBinding - no CPython linkage at all), so its own CI generates the
+# Python glue code once (the "bindings" feature, architecture-independent) and
+# then compiles the cdylib per platform. Upstream splits those two steps across
+# separate runners only to share the glue code across its many OS/arch jobs;
+# here they run as the two jobs below, narrowed to riscv64.
