MiniCPM5-1B-eyewitness — testimony→attribute parser

LoRA fine-tune of openbmb/MiniCPM5-1B that turns messy bilingual (EN/ES) eyewitness descriptions ("caterpillar eyebrows, pinta de no haber dormido, un gorro de lana") into strict attribute JSON over a closed vocabulary. Powers the EYEWITNESS game.

• Training data: 4,000 synthetic (testimony → labels) pairs generated by the game engine itself — ground truth by construction, no human labeling (generator: train/gen_dataset.py in the Space repo).
• Recipe: LoRA r=16 α=32 on all-linear, 2 epochs, bf16, TRL SFTTrainer, trained on Modal (A10G).
• Eval loss: 0.2846 (2% held-out split).

Built for the Build Small Hackathon (Thousand Token Wood track).
