House-planet relations

Catalogs every way a planet connects to a house in the chart — occupation, ownership, aspect, dispositor chains, navamsa link, nakshatra-lord link, sambandha with the house lord. Each relation carries a strength so they can be aggregated into a per-house influence score.

Ten relation types

Type	Max strength	Meaning
occupation	60	Planet physically sits in the house.
mooltrikona_ownership	55	Planet rules the house through its mooltrikona sign.
ownership	50	Planet rules the sign on the house.
aspect_to_cusp	40	Planet casts a drishti onto the house cusp.
aspect_to_occupant	35	Planet aspects another planet sitting in the house.
dispositor_placement	30	The planet's own dispositor sits in the house.
sambandha_connection	up to 30	Planet has a sambandha with the house lord.
navamsa_dispositor_placement	25	The planet's navamsa-dispositor sits in the house.
navamsa_sign_placement	20	The planet's D9 sign matches the sign on the house.
nakshatra_lord_placement	15	The planet's nakshatra-lord sits in the house.

How to aggregate

A house with planets summing to > 200 across all relation types is strongly activated. The fast triage rule of thumb:

Total strength	Reading
> 200	Densely activated — many strong ties.
100-200	Moderately activated.
< 100	Weakly activated.

Whole-sign houses are used; the orb-to-cusp modulation of the astrolink reference is collapsed to a fixed 60 Virupa for occupation so the math is reproducible.
