"""Honest label for the product Narayana Dasha (BUG-1215, round-4 ruling Q4).

`narayana_dasha.narayana_dasha_full_report` (consultation, report, CLI) runs
`calc_narayana_mahadasha`: always from the Lagna, always zodiacal. The
astrologer's ruling is Sanjay Rath's Narayana Dasha (stronger of Lagna / 7th,
order by the start sign); until the product switches (product decision after
the trial), every user-visible Narayana carries this label and the data carry
`profile: legacy_reference_only`. Kept outside `narayana_dasha.py`, which is in
the frozen rectification scoring identity (ERR-110 / ERR-115).
