@ -7,10 +7,33 @@ Extensions already covered by PLAINTEXT_EXTENSIONS, AUDIO_EXTENSIONS, or
DIRECT_CONVERT_EXTENSIONS in file_classifier are NOT repeated here -- these
sets are exclusively for the "document" ETL path (Docling / LlamaParse /
Unstructured).
Image extensions intentionally remain in the per-parser sets for fallback
compatibility. IMAGE_EXTENSIONS is used only for routing classification.
