The HULAT2-UC3M team participated in the MER-TRANS 2026 Spanish Easy-to-Read translation task with three distinct approaches. Their primary method, RUN1, utilized a LangGraph-based multi-agent workflow incorporating Gemini 2.5 Flash and RigoChat-7B-v2, achieving the highest SARI score of 44.0543. A second approach, RUN2, added a lexical-support layer to the multi-agent workflow but resulted in a slightly lower SARI score. A baseline approach, RUN3, employed a generate-evaluate-regenerate strategy with prompt engineering and LoRA adaptation, scoring 38.5136 on the SARI metric. AI
