Vedic-centric weighting prioritizes deterministic Dasha cycles over interpretive transits for timing precision.

Edge Cases We Handle
Vedic Dynamic Sade Sati
Phased, not flat: Rising (-5) → Peak (-15) → Setting (-5). Other apps flatten 7.5 years into one penalty.
Western System Isolation
Western uses True Node (osculating), Vedic uses Mean Node (averaged). Never mixed. Mixing violates both traditions.
Western Saturn Return
Ages 29-31, 58-60: Saturn conjuncts natal position. Maturation crisis or breakthrough.
Vedic Dasha Transitions
Mahadasha lord dignity modifies base score ±20. Planetary period shifts reshape the entire year.
Saju Bungchung Exception
Beom Taesal with Earth-Earth clash (Jin-Sul, Chuk-Mi) = reduced penalty (-5), not standard (-10). Activation, not destruction.
Saju Daeun Shift
10-year luck pillar transitions mark major life phases. New Daeun = new element balance.
