Kaal Sarp Yoga (काल सर्प) (時蛇瑜伽)

KAAL SARP YOGA — the serpent of time: when all seven classical planets stand hemmed between Rahu and Ketu, the chart carries one of Indian astrology's most-consulted configurations, in twelve serpent-named forms by Rahu's house — Anant (1st) through Sheshnag (12th), with the Shankhachood/Shankhnaad and Ghatak/Patak transliteration variants both served. THE ENGINE'S LAWS ARE GEOMETRIC: the hemming test proves ROTATION INVARIANCE at load — a global rotation of the zodiac can never change the verdict, across all three regimes (complete, partial, none) — plus the node-graze downgrade (a planet within a degree of either node breaks completeness, as most schools hold). The nodes are the project's Meeus MEAN node (law-checked at source, and the published Lahiri transit of Rahu into sidereal Aquarius on 18 May 2025 reproduced by test); mean-vs-true disclosed, never blended. Hemisphere direction (planets behind the head vs the tail) named; a single escapee served as the PARTIAL form most schools hold far milder; the twelve-type naming DEFERS honestly unless BOTH birth time and birthplace are supplied (the lagna sweeps all twelve signs daily) while the hemming verdict still serves; and an UN-TIMED birth gets a DECISION, not a hedge (timeSensitivity): the hemming verdict sampled across the civil day — certified when stable, exact verdict windows when the Moon crosses the nodal axis intra-day. Framed as tradition — a karmic intensifier, never a verdict. Indian becomes 26. Pure compute, no LLM.
