House strength index: the five-factor 0-100 score per house [Lumin index]

get_house_strength_index

A Lumin index, not KP and not a BPHS computation: a 0-100 score for each of the twelve houses, summed from five factors, 'occupants' (0-25: each occupant scored by dignity, combustion, motion and natural benefic class; an empty house 5), 'csl_strength' (0-30: the cuspal sub lord's dignity, combustion, motion and placement, and whether it also lords the cusp's sign), 'house_lord_placement' (0-20: the cusp sign's lord by the house it occupies), 'aspects' (0-15: from a neutral 7, each graha drishti offset falling within the orb of the Placidus cusp adds 5 for a benefic and takes 3 for any other planet, plus up to 2 for a close orb) and 'self_reference' (0-10: whether the CSL signifies its own house), graded VERY_STRONG (80+), STRONG (60+), MODERATE (40+), WEAK (20+), VERY_WEAK. Returns '{ chart_info, nodeDrishtiReading, house_strength: { scores: [{ house, total_score, factor_scores: { occupants, csl_strength, house_lord_placement, aspects, self_reference }, verdict, csl_planet, occupants, house_lord, house_lord_placed_in, stellium_detected, stellium_note, notes }], retrograde_reading: { applied, rule, retrograde_planets, astronomical, differs }, summary: { strongest_houses, weakest_houses, average_score, stellium_houses } }, houseConvention }'. The aspects factor reads the degree-exact aspects under 'nodeDrishtiReading' (the node reading used, default the 7th only); 'houseConvention' names the Placidus houses it is scored on and every planet whose house differs under whole sign. The motion deductions read KP motion, the nodes never retrograde ('retrograde_reading', with the astronomical flag beside). The weights are the engine's own and carry no source label yet (F031, F036). Built from natural benefic and malefic class, dignity and combustion, which KP judges by none of: reference and cross-system comparison only, never an input to a KP verdict. For the BPHS ch. 27 figure use 'get_shadbala'; for the house index of three components use 'get_bhava_bala'. The same block 'get_aspects_and_strength' returns as 'house_strength'.
