corvus v0.1.0 -- first tagged release
P0 special-function surface, complete and audited: erf, erfc, erfinv,
erfcinv, lgamma, regularized incomplete gamma P/Q, regularized
incomplete beta P/Q.
- C++20, std-only public API (std::span); Highway behind an internal
op facade with runtime multi-target dispatch. - Per-tier ULP bounds measured on real silicon (docs/ACCURACY.md):
AVX3_ZEN4 native + AVX2/SSE4/SSSE3/SSE2 capped (Zen 4), Linux CI
sweep + sanitizers, NEON (macOS arm64 CI), MSVC toolchain. - Reference oracles independently certified (verification harness with
baked-in negative controls). - install/export requires a system Highway (find_package(hwy >= 1.4));
FetchContent builds are build-tree-only. - API not yet stable; P1 families (digamma, inverse incomplete
gamma/beta, Bessel I0/I1) ahead.
