Pisano-tower lock: 36 = 4 × 9 = Pisano-Ψ ratio × Navagraha. Each kūṭa returns a residue from a fixed table — a deterministic residue-arithmetic computation in R, NOT a prediction.

Bride's varṇa should equal or exceed groom's varṇa per BPHS 71.4.
Same vaśya class = full 2 points. Adjacent classes get 1; distant 0.
Count nakṣatra-distance / 9. Inauspicious tāras (2,4,6,8) halve the score.
14 yoni-types based on nakṣatra. Same yoni = max; enemy yonis (cat-mouse, dog-deer) = 0.
Friendship between Moon-sign-lords. Mutual friends or same lord = 5; enemies = 1.
Deva-gaṇa best with deva or manuṣya; rākṣasa with rākṣasa only. Mismatch causes friction.
Inauspicious sign-distances (2-12, 5-9, 6-8 axis) reduce to 0. Auspicious give full 7.
Different nāḍīs (Ādi/Madhya/Antya) = 8. Same nāḍī = 0 (mahā-doṣa, requires remedy).
Strong structural compatibility. Marriage carries the support of multiple clusters. Standard auspicious muhūrta windows are usually sufficient.
Workable. Individual clusters may flag concerns; remedial-mantra and ritual alignment (vrata, dāna, varṣaphala-check) advised for the cluster-weak axes.
Structurally challenging. Especially if Nāḍī or Bhakūṭa scored zero, full parihāra-rituals are classically required before fixing the date. Always cross-read with the full chart, not the kūṭa-score alone.
Cast both birth-charts via /chart, then read the Moon's nakṣatra of each. Plugging both indices into the Aṣṭakūṭa engine produces the 8-cluster score. Always verify with the full chart (D9 navāṃśa, Maṅgala-doṣa, 7th-house yogas).
KAAL Truth #5: The Aṣṭakūṭa score is a structural compatibility metric. Any marriage decision integrates many additional factors (D9 navāṃśa, Maṅgala-doṣa, full graha-overlay, lived family context). Always consult the learned Jyotiṣī before committing — no algorithmic score replaces the full reading.
