   - Source: korean_PP-OCRv5_mobile_rec, https://huggingface.co/PaddlePaddle/korean_PP-OCRv5_mobile_rec_onnx
     (inference.onnx, repository commit 5c6f574b), sha256 92f0b7785e64fc9090106a241cf4c1eb97472824558272751b88a2a4476d3a08.
   - MODIFIED by the 멍냥체크 project (2026-10):
     a) converted from ONNX opset 7 to opset 17 (onnx 1.23.1 version converter);
     b) appended an ArgMax/ReduceMax head so the model outputs per-step character indices ("idx", int64 [B,T])
        and their probabilities ("prob", float32 [B,T]) instead of the full softmax matrix.
     The weights are unchanged; argmax output was verified identical to the original at widths 160/640/1440
     (max probability difference 1.3e-6). Modified file sha256 6083f730ef00fcc190341b1a6c142c8b64227e28bdf1349929d3ef7cfbed6118.
   - The file is gzip-compressed (level 9) for transfer.

3. dict-ko-ppocrv5.a7872c92.txt
   - Source: PaddleOCR ppocrv5_korean_dict (identical to the character_dict in the model's inference.yml), not modified.

The browser pipeline that uses these files (src/lib/ocr/paddle/pipeline.mjs in the app source) re-implements
PaddleOCR's DB post-processing, crop and CTC decoding (Apache-2.0) and follows the canvas-crop approach of
eSearch-OCR (https://github.com/xushengfeng/eSearch-OCR, Apache-2.0).

infer.worker.mjs in this folder is part of 멍냥체크 itself. It loads ONNX Runtime Web 1.30.0 (MIT,
Copyright (c) Microsoft Corporation) from /ort/1.30.0/, where its LICENSE and ThirdPartyNotices.txt are kept.
