StudyForge processing policy

StudyForge expands slash-separated spelling variants and keeps a word-level CEFR label only when every source entry for that normalized headword agrees on the same A1-C2 level. Headwords with conflicting part-of-speech or sense levels are omitted and reported as unknown at runtime. StudyForge does not infer CEFR from word frequency.
