Plan

Hypothesis. Equi-complexity/compensation: richer morphology negatively associates with word-order freedom (morph up => order freer? or morph up => order more rigid/less info-bearing). Test sign and whether it survives genealogical+areal control.

Over UD v2.15, compute per language >=2 morphological-complexity measures (mean inflectional entropy per lemma+UPOS, forms-per-lemma, feats-per-word) and >=2 word-order-freedom measures (weighted head-direction entropy per relation, core-argument placement entropy, global branching-direction entropy). Join Glottolog family+macroarea by curated UD-name->Glottocode map. Test for a NEGATIVE partial correlation under genealogical+areal control via MixedLM (crossed VC + family-RE/area-FE) and family x area stratified permutation, plus family-aggregate. Sensitivity across all measure pairs. Ship zero-download smoke repro.
