Gandanta & Gand Mool Nakshatras (甘丹塔結點)

GANDANTA — the knots of the sidereal zodiac: the three junctions where a WATER sign hands to a FIRE sign (Pisces→Aries, Cancer→Leo, Scorpio→Sagittarius), held in jyotish to be karmic seams — and the six nakshatras flanking them (Ashwini, Ashlesha, Magha, Jyeshtha, Mula, Revati) are the GAND MOOL set, the famous Moon-birth dosha with its 27th-day shanti tradition. THE STRUCTURE IS PROVEN AT LOAD THREE WAYS: the junction theorem (27×4 padas of 3°20′ tile 360°, the seams at exactly 0°/120°/240° — the ends of nakshatras 27, 9, 18); the adjacency theorem (the six DERIVED as junction-flanking pairs equal the classical list); the lord theorem (the six are exactly the Ketu- and Mercury-ruled nakshatras of the nine-lord cycle the panchanga and dasha engines already trust). ANCHORED BY AN ECLIPSE: at the published total lunar eclipse of 7 September 2025 the engine's sidereal Moon must stand in Purva Bhadrapada — placement check and Gand-Mool negative control in one. Conventions served SIDE BY SIDE, never blended: the junction pada (primary), the 1° band, the innermost 0°48′ deep gandanta with Abhukta Mula named at the Jyeshtha–Mula seam. ETHICS RAIL THROUGHOUT (the manglik precedent): a computable feature of a classical system, served as tradition-report — never a verdict on any child or person. Indian tradition grows by one. Pure compute, no LLM.
