  abstract  = {KrenTransV0-1 is MWire Labs' submission to the WMT 2026 Low-Resource Indic MT Shared Task. We achieve \#1 primary rank on both English→Khasi and English→Kokborok. The system covers all 11 Northeast Indian language pairs using a hybrid architecture combining fine-tuned IndicTrans2 for Indic-script languages, NLLB-200 1.3B mono fine-tuned models for Latin-script languages, and M2M-100 418M fine-tuned models for three severely data-starved languages that exhibited complete output collapse under NLLB. All submissions are primary, covering the English-to-target direction only. We additionally report a negative reranking result: neither BharatGen PARAM-1 (2.9B) perplexity reranking nor NE-BERT fluency reranking improved over a beam-search baseline, and all final submissions use the baseline decoding configuration.},
