Display only; scoring and timing conclusions keep the legacy algorithm.
narayana_legacy_label attaches a Rath view (seed, deciding level, direction,
24 MDs, running MD/AD) under modules.narayana_dasha.rath for the consultation
modules, full reading Step 4.13 and the CLI. Reference report: one summary
line under the legacy line plus Rath MD / running-MD AD tables (English terms
added). Evidence card: narayana_rath (label, seed sign, level, running MD) on
timing / annual cards only — other cards sit at 11,979 of 12,000 characters.

Round-4 ruling Q4 / product decision A: scoring and the consultation and
report time axes keep the old Narayana (from the Lagna, always zodiacal) until
the Rath trial is decided; every user-visible Narayana now says so.
narayana_legacy_label adds profile=legacy_reference_only and the note (zh/en)
at the consumers (consultation modules, full reading Step 4.13, CLI), not in
the frozen narayana_dasha.py (ERR-110/115). The card's timing.narayana carries
'algorithm'; the projection allowlist passes algorithm_note; the reference
report's Narayana section and the dasha-family table show '算法：…' (English
twin in the phrase table). The unused narayana-dasha --variant-profile flag,
the one place offering a Chara Dasha author's profile for Narayana, is removed.

Narayana Dasha is Parashara's rashi-based dasha system, complementary to
Vimshottari (nakshatra-based). Algorithm: start from Lagna, each sign's
dasha years = count from the sign to its lord's sign (zodiacal order).
Implementation:
- scripts/narayana_dasha.py: core calculation module
- calc_narayana_mahadasha(): 12-sign sequence from Lagna
- calc_narayana_antardasha(): sub-periods within each MD
- get_current_narayana_dasha(): locate current period by age
- scripts/cmd_narayana_dasha.py: CLI subcommand
- jyotish_engine.py: Step 4.13 in full-reading + narayana-dasha subparser
Verified with Leo Asc chart: total cycle 88 years, current Sagittarius MD
(31-38 yrs, 5H/creativity) complements Vimshottari Saturn MD.
