Hospitalization Window (natal promise + dated confinement windows)

get_hospitalization_window

Natal 12th-house confinement analysis. Promise gate on the 12th CSL: signifying 6 and/or 8 makes the confinement illness-driven (PROMISED); only 3/9 reads as travel/retreat (WEAK, non-medical); neither is DENIED. Walks the MD/AD/PD calendar for windows where the three lords jointly activate the 12th with an admission driver — typed ADMISSION {12,6}, SURGICAL_OR_ICU {12,8}, CRITICAL {12,8,bhadhaka}, DAY_PROCEDURE {12,1} (the confinement group is 1/6/12 per KP Reader 3 canon p.293, "if the significator of the sixth house is also the significator of 1 and also 12 one will be confined to bed"; it used to carry the 5th, which is the CURE house) — chronological, capped at 12, with Saturn (prolonged-stay) and Mars (emergency/acute) transit confirmation sampled at each window midpoint. Duration class from the 12th CSL's occupied sign modality: movable=SHORT_STAY, fixed=PROLONGED, dual=REPEAT_ADMISSIONS. Supplementary lens, not medical advice or 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.
