Anvaya uses KP/Krishnamurti ayanamsha with Placidus cuspal houses, while Parashari lordship and yoga rules use whole-sign houses. Strength calculations use compound panchadha friendship; plain chart labels use natural friendship for readability. Declared conventions cover Sripati as a school-variant house system, Taurus/Scorpio nodes, post-classical D6 as a supporting health witness, Tajika night saham reversal, activity-scoped Panchaka, refined 5-9 Bhakoot, MM.2 guna-milan / Stree-Deergha / vedha rules, disc-center sunrise, purnimanta masa, BPHS Mangal houses, Santhanam D60 recension, and classical D9-only Ishta derivation.
- KP / Krishnamurti
- Keeps natal, panchang, muhurat, and Tajika frames aligned.
- Placidus cuspal default; whole-sign for lordship/yoga (HR 24.1)
- Preserves KP cuspal house reads while keeping Parashari lordship/yoga canonical.
- Placidus (KP) primary + whole-sign for lordship/yoga
- Sripati is available as a Bengali-school variant without displacing the KP default.
- Compound panchadha for Bala/strength; natural friendship for plain labels
- Strength requires natural × tatkalika relationship; surface labels stay readable.
- Post-classical D6 extension; odd signs from Aries, even signs from Libra; multi-witness health only
- D6 is not part of the classical shodashavarga; stability plus disclosure beats unsourced switching.
- Rahu Taurus, Ketu Scorpio
- Node exaltation has no single consensus; readings keep node dignity low-weight.
- Night reverses A-B+C to B-A+C by default; Vivaha, Bhratri/Bhratru, and Roga do not reverse
- Makes day/night Varsha Pravesha treatment explicit.
- Classical Janma Panchaka span; weekday table removed; activity-scoped DQ
- Avoids confident wrong weekday gates and over-rejection outside governed activities.
- 5-9 (nava-pancham) Bhakoot is not a dosha; only 2-12 and 6-8 pairs score zero
- Preserves supportive nava-pancham treatment while keeping other bad pairs gated.
- Same-animal yoni pairs use gender-refined half-points (4.5/4.0/3.0), capped at koot max 4
- Discloses gender-refined half-points instead of silent integer rounding.
- Koot scores stored and summed as floats in 0.5 steps; totals may be fractional
- Preserves classical half-point arithmetic through the full ashtakoota sum.
- 13-threshold school: bride-to-groom nakshatra count must exceed 13; same-nakshatra always fails
- One classical threshold implementation avoids competing Stree-Deergha forks.
- Classical thirteen obstruction pairs; Chitra vedha-exempt
- Keeps vedha on classical pairs rather than an unsourced arithmetic mirror.
- Swiss Ephemeris rise_trans with BIT_DISC_CENTER (solar disc center)
- One sunrise limb convention shared by panchang and Varshaphala day boundaries.
- Purnimanta kernel (day_context: sunrise JD, adhik-maas, Krishna-1 advance)
- Aligns masa naming with the North-Indian purnimanta day-context kernel.
- Parashari lagna-primary set {1, 4, 7, 8, 12}; 2nd house omitted
- Uses the strict BPHS house list and discloses the 2nd-house school variance.
- Mars in Cancer treated as hard cancellation (is_cancelled=True)
- Boolean cancellation is strict while prose hedges the minority-school basis.
- Kantha (wife longevity) strand ranked caution when matched; Nabhi/Siro incompatible
- Discloses Tamil porutham severity variance for Kantha vs Nabhi/Siro.
- Santhanam BPHS Ch.6 deity listing; Phaladeepika 3.5 krura positions for valence
- Pins D60 deity names and valence to a disclosed Santhanam/Phaladeepika recension.
- Shashtiamsa never derives, confirms, or tie-breaks Ishta Devata; classical D9 hierarchical chain only
- Keeps Ishta on the classical D9 chain; D60 amsa does not elect or confirm.
- Classical Jaimini chain occupant>aspector>lord in Navamsa frame (12-from-Karakamsa per Rath/PVR convention)
- Uses the classical occupant→aspector→lord chain in the Navamsa Karakamsa frame.
- Dignity rank first; higher D9 deg_in_sign among tied candidates
- Makes Ishta ties deterministic via dignity then D9 degree advancement.
- Slash deity entries resolve to primary_form per register (e.g. Mars vaishnav Hanuman; shaiva Skanda with Bhairava secondary); practice/yantra anchors on primary_form
- Resolves slash deities to a disclosed primary form per theological register.
- Lagna and Moon amsa claims require rectification_complete or ≥30 min boundary clock; grahas ineligible within 0.01° of amsa boundary
- Gates fragile D60 amsa claims behind birth-time precision / rectification signals.
- D60 deity-amsa layer does not feed matchmaking verdict_home scoring or prose
- Keeps matchmaking verdict free of D60 amsa claims that lack classical couple basis.
