# Third-party notices — Typing keyboard

The generated Chinese source manifest is
`OSGKeyboardShared/Resources/Typing/Rime/manifest.json`. Exact librime
binary dependency licenses are bundled beside `NOTICE.txt`.

sources into `osg_pinyin.dict.yaml`; its manifest records every source URL,
commit, SHA-256 and output SHA-256.

## OSG-owned pieces

- SwiftUI QWERTY / candidate UI, `RimeEngineBridging`, and the English
  suggestion / autocorrect / next-word session layer.
- Objective-C++ C-API bridge for librime.
- Full-pinyin, Microsoft-double-pinyin and Sogou-double-pinyin schemas.
- Microsoft/Sogou mappings were independently encoded from public key-map
  specifications; GPL schema files were not copied.
- Eight opt-in fuzzy-pinyin rule groups.
- Offline English typing data under
  `OSGKeyboardShared/Resources/Typing/English/`:
  - `english_lexicon.tsv` — curated word list with synthetic relative
    frequency ranks for autocomplete / autocorrect
  - `english_bigrams.tsv` — light next-word candidates
  - Not derived from GPL/LGPL dictionaries; ranks are ordering weights,
    not a single third-party corpus dump
