Narayana Dasha is Parashara's rashi-based dasha system, complementary to Vimshottari (nakshatra-based). Algorithm: start from Lagna, each sign's dasha years = count from the sign to its lord's sign (zodiacal order). Implementation: - scripts/narayana_dasha.py: core calculation module - calc_narayana_mahadasha(): 12-sign sequence from Lagna - calc_narayana_antardasha(): sub-periods within each MD - get_current_narayana_dasha(): locate current period by age - scripts/cmd_narayana_dasha.py: CLI subcommand - jyotish_engine.py: Step 4.13 in full-reading + narayana-dasha subparser Verified with Leo Asc chart: total cycle 88 years, current Sagittarius MD (31-38 yrs, 5H/creativity) complements Vimshottari Saturn MD.
