`catalog.json` is a list of image records; `images/` contains the corresponding files. Paths are relative to this directory. The initial selection contains 1,000 images.
Each record contains a stable `id`, image path, exact reference `text`, source `category`, reference `scope`, annotation `quality`, `reading_order_known`, optional word `regions`, and `source` provenance/rights. Source references and word regions are evaluation annotations, never hints to the OCR engine.
Keep source transcripts exactly as supplied. `target_text_only` references cover a selected target instruction, not necessarily all text visible in the image. The initial references have silver quality; preserve that distinction when reporting results. Dataset records and image bytes should be reviewed together.
The loading, metrics and runner code lives under `research/ocr_eval/evaluation/` in the [VIPI code repository](https://github.com/EnXan/VIPI).
