# CORD structured-extraction (LoRA training set)

200 train + 20 val examples derived from CORD (naver-clova-ix/cord-v2, train
split). Each example pairs a **preprocessed** receipt image with the **target
extraction JSON** (receipt fields + line items in the pipeline's schema).

- `prompt.txt` - the shared instruction (schema skeleton injected)
- `train.jsonl` / `val.jsonl` - lines of `{"id", "image": "images/..png", "target": "<json>"}`
- `images/` - the preprocessed pages (deskew / resize<=1536 / denoise)

Used to QLoRA-fine-tune `sarcasticcoder/qwen2.5-vl-7b-cord-lora`.
