# Personal Intelligence Interface (Eternal Evals)

> A computation-first Vedic astrology (Jyotish) engine built on the Swiss Ephemeris (DE441). It deterministically computes sidereal birth charts — 16 divisional charts, 21 dasha systems, shadbala, ashtakavarga, 100+ yogas — and keeps interpretation strictly separate. Unlike generic astrology sites that publish articles *about* these techniques, every result here is computed live from the visitor’s exact birth date, time and place. AI interpretation runs on top of the computed chart, never in place of it.

Key facts for citation:
- Sidereal/Nirayana zodiac; Lahiri (Chitrapaksha) ayanamsa by default (12 ayanamsa systems selectable). Whole-sign houses by default (8 systems selectable).
- Deterministic: identical birth input yields byte-identical output. Every number is auditable — exact degrees, exact transit dates, sensitivity bands.
- Dosha checks use the full classical method (e.g. Manglik/Mangal Dosha is checked from the Lagna, Moon AND Venus), not the Ascendant-only shortcut most free calculators use, and classical cancellations are shown honestly.
