From 525a0e11149bc7d68e85e022e41143437920d7b1 Mon Sep 17 00:00:00 2001 From: Alpamys Date: Tue, 26 May 2026 16:43:17 +0500 Subject: [PATCH] feat(brain-rot): per-language low-effort + clickbait bundles for es/fr/de/ru (#234) Extends v0.69.0 Part E score_triviality + score_popularity_signal to non-English corpora. New utils/brain_rot_lang.py ships a MappingProxyType registry of frozen BrainRotLangBundle for en/es/fr/de/ru. Every public scorer accepts an optional lang kwarg (default None preserves v0.69.0 English behaviour). The "auto" sentinel routes through the v0.53.10 [data-pro] langdetect helper with silent fallback to English on missing-package / detector-exception / unsupported-code. soup data brain-rot gains --lang en|es|fr|de|ru|auto, strictly validated at the CLI boundary (exit 2 on typos). Per-row resolution backed by eager _validate_lang_arg on dataset scorers so empty rows cannot bypass shape checks. Closes #234.
