+Subject: [PATCH] Fix gb_trees iterator exhaustion for OTP 27
+
+In OTP 27, gb_trees:next/1 returns 'none' when the iterator is
+exhausted, instead of the empty list '[]' as in previous versions. The
+encode_as_reference/2 function only handled the '[]' case via a function
+clause, causing a {case_clause, none} crash at runtime when encoding
+objects, arrays or typed objects.
+
+Add a 'none' clause to the case expression to handle iterator exhaustion
+correctly under OTP 27 while remaining compatible with older OTP
+versions.
+
+Fixes FTBFS on Fedora Rawhide (OTP 27).
