🎯 Significators — star vs. sub division of labour (Chapter I.10, p. 23)
"The significator gives during its period, sub period or inter period the results of its star lord. The sub lord of the significator shows whether these results will be favourable or unfavourable."
→ Drives the A/B/C/D table in 🎯 Planetary Significators. Star-lord = what, sub-lord = how.
🔍 Cuspal Sub-Lord — the central rule (Chapter I.13, p. 29)
"The sum and substance of the sub disposition theory of prediction is that the cuspal sub lord of a house indicates whether the matter signified by the house is promised or denied. If the cuspal sub lord promises, then only during the joint period of the significators of that matter the results of that matter are experienced; otherwise not."
→ Drives the Promised / Partial / Denied verdicts in 🔍 Cuspal Sub-Lord Analysis.
🕰️ Dasha — transit-verification at the event (p. 105)
"At the time of event Sun, Moon and/or the joint period rulers will be found in the star or sub of the same joint period ruler or rulers."
→ At fructification, the fast movers (Sun ~13 d/star, Moon ~24 h/star, ~3 h/sub) transit the star or sub of one of the MD/AD/PD rulers shown in 🕰️ Vimshottari Dasha.
🕐 Ruling Planets — definition + retrograde rule (Chapter II, pp. 43 + 52)
"The sign lord of the Asc, the star lord of the Asc, the sign lord of Moon, the star lord of Moon at the time of query or judgment and the day lord are called the 'Ruling Planets'."
"A retrograde ruling planet shall give the results only when it becomes direct in motion."
→ Drives 🕐 Birth Time Rectification (BTR). Five base RPs; Rahu/Ketu added when they conjoin/aspect an RP or tenant an RP's sign.
🔢 Sub formula — the arithmetic underneath everything (p. 5)
"Dasha years of each planet ÷ The total number of Vimshottari Dasha years × Star area = The longitude or extent or area of the Sub for each planet in any Star or Constellation or Nakshatra."
→ Drives the 249-sub table. Validated 2026-05-22 against canonical Vimshottari math — zero arc-second deltas across all 249 rows.
Where this lives in the app: the four panes named in the cards above (Significators, CSL, Dasha, BTR) each implement one of these rules. This card collects them in one place; the original pane-level citations were removed 2026-05-22 to avoid repetition.
