## ddddocr

DSH Patrol's optional owned-site CAPTCHA demo helper installs and imports `ddddocr` 1.6.1 from PyPI at local setup time. The ddddocr project is distributed under the MIT License.

- Upstream: https://github.com/sml2h3/ddddocr
- License: MIT
- DSH Patrol does not vendor or modify ddddocr's source or model files in this repository; the optional local Python virtual environment is ignored by Git.

## Text_select_captcha

The public `MgArcher/Text_select_captcha` repository was reviewed for its documented architecture and API shape. At the time this integration was implemented, the repository did not publish a license through GitHub and did not contain a root LICENSE file, so DSH Patrol does **not** copy, vendor, redistribute, or import its source/model files. The owned-site ordered-click implementation in DSH Patrol is an independent implementation using ddddocr detection/OCR plus local image processing.
