c41555f69e
Astrologer round-5 Q1-Q4 in scripts/narayana_rath.py (frozen narayana_dasha.py untouched). Levels 1-2 are upstream c7117f92's rath_p36_role_conjunction_v1 counting (test compares with the upstream function); Ketu reversal is the upstream rath_ketu_table12_v1 branch; Ketu first when Saturn shares the seed. Book tables: 15 Cancer (level 1) and 17 Pisces (level 2) reproduce; 18 gives Capricorn at level 5, so the Indira AK example (full tie only) is never reached -> red line 3: no T4 wiring, no T5 trial.

"""Narayana Dasha, Sanjay Rath profile (`sanjay_rath`) — research only (BUG-1215 / BUG-1218).
|
|
|
|
Astrologer round-4 ruling (Q4): the second time axis should be Sanjay Rath's
|
|
Narayana Dasha. Round-5 ruling 2026-10-03 fixed the open points (book pages
|
|
in brackets; Sanjay Rath, *Narayana Dasa*):
|
|
|
|
Start sign = the stronger of Lagna and 7th [p.48]. General rule, seven levels,
|
|
stop at the first level that separates the two signs, no weighting [p.35-36,
|
|
p.63]:
|
|
|
|
1. more occupants (actual bodies, Rahu/Ketu included);
|
|
2. more support from three roles — Jupiter, Mercury and the sign lord — each
|
|
role counted once when the planet is in the sign or casts Rasi Drishti on
|
|
it [p.48; no graha drishti]; roles are not de-duplicated by planet
|
|
(Jupiter as Jupiter and as lord counts twice) [p.36];
|
|
3. occupant dignity: exalted > moolatrikona > own sign (whole sign) — best
|
|
rank, then the number of dignified occupants;
|
|
4. dual > fixed > movable;
|
|
5. the lord's degree inside its sign, Chara Karaka sense (higher is
|
|
stronger; Rahu / Ketu as 30 - degree);
|
|
6. the lord placed in a sign of the opposite parity to the sign it rules;
|
|
7. the sign giving the longer dasha.
|
|
"Contains the AK" / "lord is the AK" are not general rules [p.35]. The
|
|
Indira example (p.65-66) decides Cancer by the AK; it is kept as a flagged
|
|
book example (`book_example_exception: rath_p66_indira_ak`), used only when
|
|
all seven levels tie.
|
|
|
|
MD order: Table 10 by the start sign [p.51]; Saturn in the start sign -> zodiacal,
|
|
sign by sign (Table 11) [p.51-53]; Ketu in the start sign -> Table 10 direction
|
|
reversed, keeping the fixed / dual stepping (not the whole table read
|
|
backwards) [p.51, p.53 Table 12; p.54 Table 14 is the AD table]. Saturn and
|
|
Ketu both in the start sign: Ketu first (PyJHora's practice, product owner
|
|
ruling 2026-10-03, `method_note`).
|
|
|
|
Years: `jaimini_odd_footed_dignity_v2` (odd/even-footed count, fixed-sign
|
|
exception, exalted +1 / debilitated -1); Scorpio / Aquarius lords by
|
|
`jaimini_dual_lord_source_v1`. Cycle 2 = 12 minus cycle 1.
|
|
|
|
AD [p.48 Arambha Rasi, p.50 note 2]: compare the MD sign and its 7th with the
|
|
same seven levels, take the stronger, start from the sign holding that sign's
|
|
lord (dual lords by the same rule), twelve equal parts. Order: Table 13 from
|
|
the start sign; Saturn in the MD sign -> Table 11 (zodiacal); Ketu in the MD
|
|
sign -> Table 14 (Ketu first when both).
|
|
|
|
Ported verbatim from upstream yinduzhanxing c7117f92 `scripts/narayana_dasha.py`:
|
|
`_rath_ketu_table12_sequence` (the `rath_ketu_table12_v1` branch of
|
|
`build_narayana_sign_sequence`), `_RATH_CLASSICAL_MOOLATRIKONA_SIGNS`, and the
|
|
level 1-2 counting of `select_narayana_seed_sign(strength_profile=
|
|
"rath_p36_role_conjunction_v1")` (`_role_candidate`; tests compare it with the
|
|
upstream function). Tables 10 / 11 / 13 / 14, `_rasi_aspects`, the year and
|
|
dual-lord functions are the same in both repositories and are reused from the
|
|
frozen local `narayana_dasha.py`, which this module does not modify.
|
|
|
|
Not wired into scoring, consultation or reports (task red line 3: Table 18 is
|
|
not reproduced by the general rule, see tests/test_narayana_rath_book_tables.py).
