Moira

An auditable astrology engine with explicit computational policy, deterministic behavior, and readable reduction stages grounded in modern standards and references including JPL DE441, IAU 2000A/2006, ERFA/SOFA-aligned practices, and Gaia DR3-linked star data where applicable. A required C++17 extension (_moira_native, compiled with pybind11) accelerates admitted numerical substrates including nutation, SPK/DAF access, apparent-place evaluation, coordinate transforms, harmogram computation, and selected event-search primitives. Python remains the governing layer for public semantics, doctrine, policy, and orchestration.
