Progeny Promise (KP)

get_progeny_promise

Whether children are promised. The 5th cusp sub lord on 2/5/11 (promise) against 1/4/10 (denial), its retrograde state and its star lord's (read as KP reads motion, the nodes never retrograde; 'promise.retrogradeReading' carries the astronomical reading beside it, F160); the Jupiter karaka on 6/8/12; the 5th cusp sign as fruitful, semi-fruitful or barren. The three combine into 'overallVerdict'; the IVF/assisted signals and the miscarriage score (an engine figure) are read off the same promise. Returns '{ overallVerdict: NATURAL | IVF_OR_ASSISTED | DELAYED | DENIED | MIXED, promise: { fifthCSL, fifthCSLStarLord, fifthCSLRetrograde, fifthCSLStarLordRetrograde, cslSignifies, promiseHousesCovered, denialHousesCovered, lossHousesCovered, miscarriageSignal, promiseVerdict, rationale, retrogradeReading }, jupiterKaraka: { jupiterSignifies, afflictedHouses, isAfflicted, rationale }, fifthCuspSign: { sign, classification, rationale }, ivfOrAssistedSignals, miscarriageRiskScore, bookCitations, disclaimer }'. The same fields 'get_fertility_window' returns under those names. Supplementary lens, never a fertility diagnosis.

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.
