KP Significators & Cuspal Sub Lords
Two related KP-system tools: "Significators" lists, per house, which planets are considered capable of delivering results for that house's matters (based on their own placement and connections); "Cuspal Sub Lords" applies the same Sub Lord/Sub-Sub Lord logic (see KP System above) to each house's exact Placidus cusp degree, not just to planets.
A house's Cuspal Sub Lord is considered by KP practitioners to be highly decisive for whether that house's matter will materialize — used alongside the Significator list to build a prediction.
Significators are built from a planet's own house placement, the house(s) it owns, and its Nakshatra lord's placement/ownership — Cuspal Sub Lords use the exact Placidus cusp degree (see Bhava Chalit below) run through the same Sub Lord segmentation described in the KP System entry.
