+    (a) install and use the SDK **in object-code form only** together with
+        the Wrapper, in products and services that You develop or operate;
+    (b) reproduce and redistribute the unmodified SDK solely when it is
+        embedded in an application that **depends on the Wrapper**, provided

+        • do not charge a fee specifically for the SDK.
+
+2.  Restrictions
+    You shall not, and shall not allow any third party to:
+    • modify, translate, reverse-engineer, decompile, disassemble or

+    • remove or obscure any proprietary notices;
+    • use the SDK to create or train competing speech-enhancement models;
+    • redistribute the SDK as a stand-alone product, via package registries
+      (PyPI, npm, crates.io, etc.), or in any manner that allows third
+      parties to access the SDK separate from Your application.
+
+3.  Proprietary Rights

+5.  Limitation of Liability

+    their respective terms.
+
+9.  Entire Agreement
