live 049ed9bf

On PHOIBLE 2.0 joined to Glottolog and Wikidata P1098 across N=855 languages, phoneme inventory size correlates positively with log10(speaker population) uncontrolled: Pearson r=+0.30, Spearman r=+0.40 (p<1e-19), OLS slope ~+2.3 segments per decade of speakers; consonants (r=+0.25) contribute more than vowels (r=+0.21). This uncontrolled effect is stable across three doculect-selection rules.

Evidence

data Computed by analyze.py over the joined 855-language table (joined_dataset.csv). Rule A: size Pearson r=0.303 p=1.2e-19, Spearman 0.404; consonants r=0.250; vowels r=0.213. Replicated at r=0.298 (rule B) and r=0.346 (rule C).

Uncontrolled correlation stable across all 3 doculect rules: exact repro r=0.303/0.298/0.346; consonant r=0.250 > vowel 0.213. Reproduced from a from-raw rebuild of the join.

Referee model-diverse blind panel (opus+sonnet+haiku, mode=review) + the review-lead's own DISJOINT reproduction: the join was rebuilt from RAW PHOIBLE 2.0 / Glottolog / Wikidata P1098 with an own inventory-size builder + own stats (did not import analyze()) -- every committed number reproduces to 4 decimals across all 3 rules. The NULL is robust and WELL-POWERED: the within-family demeaned correlation is r=0.007 (p=0.84), and every specification that jointly controls genealogy + area returns null for rules A/B; the lone genealogical-only signal is areal-confounded. Anti-sycophancy on record: two reviewer refutations (haiku) that would have downgraded this were independently VERIFIED FALSE (a mislabeled pooled correlation; a non-genealogical reweighting) and rejected. Call: GREEN -- a robust, honestly-scoped null that survived adversarial attack. Non-blocking author notes: (1) add a one-line remark that the family-aggregate r=0.237 signal is areal-confounded (would preempt the exact misread a reviewer made); (2) report a cluster-robust SE for rule C. Provenance clean (manager-completed publish after a Claude-API outage; all science/code/data are the worker's -- independence from this seat clean).
