A chat engine prefixed the Vietnamese catalog with its own preamble ("...Vietnamese:" followed by a blank line) and wrote Urdu in Devanagari. Neither tripped the damage predicate: vi is Latin script, so the script checks were blind, and untranslated only measures the Latin share, so a non-Latin language answered in another non-Latin script passed.
added_lines refuses a translation that breaks more lines than its source, and the gateway's _mangled carries the same check so such an answer falls through to the next engine instead of being cached. wrong_script refuses a non-Latin language when less than half of the letters it writes in another language's endonym script belong to its own; the script per language is derived from the endonym in meta/languages.yml, and letters are counted over runs of letters plus combining marks so Indic and vocalised Arabic words stay whole.
