| # v12.0.0 moved bindings/CMakeLists.txt from pybind11 to nanobind's split mode | |
| # (nanobind_add_module(... BACKEND_MODULE nanobind_backend STABLE_ABI_VERSION | |
| # 3.11)): pyproject.toml now sets `wheel.py-api = "cp311"`, so cibuildwheel | |
| # produces a single cp311-abi3 wheel that covers every newer non-free-threaded | |
| # interpreter (CLAUDE.md gotcha 11), and upstream's own python-dist.yml builds | |
| # it once per OS with no interpreter matrix at all. Building it on cp312+ | |
| # here (as the old per-interpreter pybind11 matrix did) would tag the wheel | |
| # cp311-abi3 while compiling it against newer headers than the tag claims | |
| # (gotcha 96), so build on cp311, the floor the tag actually promises. | |
| # | |
| # Free-threaded (cp314t) is dropped: nanobind-backend>=1.0 publishes no | |
| # cp313t/cp314t wheel on *any* platform (only cp315t), so pyslang ships no | |
| # free-threaded wheel upstream either (the litellm/gotcha-11 "abi3-only, no | |
| # cp314t variant" shape) -- this is an upstream gap, not riscv64-specific. | |
