Station Windows

get_station_windows

T12: the days in the scan when Jupiter or Saturn stations ('stationPoints', retrograde or direct, found by a day-by-day change in the direction of motion), and which of the event's significators sit within 3 degrees of a station ('significatorMatches'). The release is Sutra 32 (KP Reader 6 canon p.155: a retrograde planet gives its results once it is direct again and passes the point where its retrograde motion began); the 3-degree orb is the engine's. Returns '{ event, requiredHouses, scanStartDate, scanEndDate, stationPoints: [{ planet, date, longitude, stationType: STATION_RETROGRADE | STATION_DIRECT, speedBefore, speedAfter }], significatorMatches: [{ station, significatorPlanet, significatorLongitude, orb, houses }], summary }'. The same block 'get_retrograde_panel' returns as 'stationWindowMapping'.

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.
