+Bendyline Knowledge - repository and dataset licenses
+
+1. General license and scope
+============================
+
+The MIT License below applies to Bendyline's original pipeline code, original
+project documentation, and original dataset metadata, unless a more specific
+license is identified. Imported catalog content and adaptations of that content
+retain their applicable source licenses. The MIT grant does not replace them.
+
+The per-catalog list in section 2 identifies the applicable licenses and notices.
+It describes catalogs registered in the source repository; a listing does not
+mean that a compiled release has been published. For a particular release, use
+the license texts, attribution, source revisions, and notices shipped with that
+release. Later changes to this overview do not change earlier release licenses.

+2. Per-catalog licenses
+======================
+
+License summaries are a guide to the full terms, not additional restrictions or
+substitute licenses. Retain the applicable license texts and notices when
+redistributing material. For CC BY content, retain attribution and identify
+modifications. For CC BY-SA content, also license shared adaptations under the
+applicable ShareAlike terms. Follow the full license for the material you reuse.
+Source-specific notices and separately identified third-party material remain
+subject to their own applicable terms. This file grants no trademark rights or
+endorsement by the original publishers.
+
+Each .gezk contains LICENSES/ with full license texts and catalog notices, plus
+source provenance where applicable. Hugging Face release directories also carry
+license sidecars. The source records linked below provide the current catalog
+definitions; the records bundled with an immutable release describe that release.
