Event Dasha Periods
get_event_dasha
Find which Vimshottari dasha periods activate a specific life event. Filters to periods where MD+AD lords jointly signify the required houses; ranks by signification coverage. Returns '{ event, requiredHouses[], periods: [{ md, ad, startDate, endDate, coveragePct, supportingHouses[] }], eventResolution }'. If 'event' is omitted, the engine derives the most active event from the running MD+AD signification with RP tie-break. For 3-level (MD+AD+PD) timing + RP filtering + transit hierarchy, prefer 'find_event_timing_v2'.

}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.
