The pinned upstream README identifies `ara_atb` as PATB/CalimaStar-derived
inflection data, `ara_new` as a consistently processed subset of the earlier
`ara` lemmas, attributes both to Salam Khalifa and Nizar Habash, and applies

Revision status: recorded

Radixor modifications: Verification of both pinned source files, NFC normalization, filtering to Unicode letters, numbers, and combining marks, grouping inflected forms by lemma, exact deduplication, deterministic GZip packaging, and generation of runtime descriptor and checksum metadata. The reproducible import is implemented by `tools/import-unimorph-arabic.py`.

The derived model data is distributed under CC BY-SA 3.0. UniMorph supplies morphological data; Radixor constructs its own patch-command trie at runtime. Neither UniMorph nor any upstream contributor endorses Radixor.
