| # CI: build and test both backends on every push/PR. | |
| # | |
| # Two test jobs run in parallel: | |
| # test-bitexact — NUMPYCPP_STD_ONLY=OFF → must be GREEN (900/900 bit-exact) | |
| # test-std — NUMPYCPP_STD_ONLY=ON → informational only (continue-on-error) | |
| # std::exp/log/pow/atan2 and C++ loops are intentionally NOT bit-exact vs numpy. | |
| # Failures here document the precision gap — they do NOT block the build or DEB. | |
| # | |
| # DEB packaging: single DEB (header-only — backend is consumer's compile choice) | |
| # cmake .. → numpycpp-dev-<ver>-Linux.deb | |
