Sonar Municipal PTT5 base fine-tuned (LoRA, merged) for ementa-to-action textualization

PTT5 base (unicamp-dl/ptt5-base-portuguese-vocab, 220M params) fine-tuned with LoRA and merged into the base for distribution (loads with AutoModelForSeq2SeqLM.from_pretrained, no peft dependency at inference) for semantic textualization of Brazilian municipal legislative bill summaries (ementas) into direct imperative action form. Companion artifact to the ICMC-USP undergraduate thesis "Mineração de Dados e Busca Semântica Aplicadas à Análise de Projetos de Lei Municipais" (Sonar Municipal project).
