Ported from yinduzhanxing 0afa2780 (algorithm hunks and its four regression tests; the PyJHora / profile-metadata hunks do not apply to our file). The archived-PyJHora Kala test follows upstream's rewrite. The V.P. Jain benchmark expectations still need the three-column update (follow-up in this branch). TASK-upstream-sync4-20261002 T3.
