Ashtama Sani and Ardha-ashtama, read by star lord

get_ashtama_sani

Saturn in the 8th sign from the natal Moon (Ashtama Sani, ~2.5 years) and in the 4th (Ardha-ashtama, also called Kantaka Sani), every window across the life, each decomposed into one entry per nakshatra Saturn crosses inside it. **The window is not the verdict.** KP Reader 5 devotes four chapters to saying so: Ch.42 "Is Chandra-Ashtama ever evil", Ch.43 "Chandrashtama and its truth", Ch.45 "Ashtama Sani and Honour", Ch.53 "Traditional Transit System - Meaningless". canon p.290: the blanket adverse reading "is incomplete", because "in which cases Sani is a benefic and in which cases Ashtama Sani is evil, has not been scientifically discussed elaborately"; canon p.286 heads a worked example "the honour and reputation conferred on a Hotel Proprietor and his success in the competition during Ashtama Sani". The KP verdict is chart-dependent and comes from 'starLordWindows[].reading', judged on that star lord's house lordship in THIS chart: signifying 8 or 12 is adverse (canon p.298), 10 or 11 benefic (canon p.297). 'currentStatus' says whether either is running now. A verdict of UNKNOWN means significators were unavailable, so report that there is no KP verdict rather than falling back on the window's name. Companion to 'get_sade_sati_phases', which returns these two families as dates only. Books: KP Reader 5 canon pp.277-290, pp.296-299.

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.
