Retrograde Dasha Lord Activation

get_retrograde_dasha_activation

T10: which of the running Mahadasha, Antardasha and Pratyantardasha lords were retrograde at birth ('retroDashaLords'), and the dates in the scan when transit Jupiter or Saturn comes within 2 degrees of such a lord's natal degree, sampled every 3 days, one hit per pair per 30 days. Reads no event. No source has been found for the rule or the 2-degree orb (the corpus was searched 2026-09-28): present it as the engine's, not KSK's. Returns '{ retroDashaLords, scanStartDate, scanEndDate, hits: [{ dashaLord, natalRetroDegree, transitPlanet, transitDate, transitLongitude, orb }], summary }'. The same block 'get_retrograde_panel' returns as 'retroDashaActivation'.

Birth data

This tool requires birth data on every call. The MCP server is stateless, so calling set_birth_profile first validates the data and returns the reading plan, but it does not store anything. Repeat the same five fields here.
