about

nx_stem.nx -- SOVEREIGN morphological stemming (the stemming/lemmatization SOTA-parity rung; sota_stemming canon). Inflected forms map to a common conflation root so a query recalls all forms: run/running/runs, rank/ranking/ranked, index/indexes/indexing. Upgraded 2026-07-03 from Step-1a-only to a PORTER-LITE stemmer (the high-recall steps: plurals + -ed/-ing + -ly + common derivational suffixes) with Porter's measure(m) guard that stops over-stemming short words. NO index-format change: it drives QUERY-TIME dictionary expansion (dss_stem_expand), so indexing is untouched. HONEST SCOPE: no irregulars (children->child needs a lexicon). exports: nx_stem (buffered) + vr_stem (in-place, backward-compat). license_tier: ORIGINAL
