 A Property Descriptor has one metadata store. Its entries are either Attributes or Constraints.

+An `Object_Schema` may additionally contain type-level Attributes supplied through
+`type_metadata(...)`. This is the single metadata store for facts about the described type;
+it is deliberately separate from property metadata and from inheritable property defaults.
+Core applies the same Attribute protocol and category uniqueness rules without interpreting
+extension-owned type semantics.
+
 Core and extensions share one Attribute mechanism for descriptive metadata. An Attribute owns a category and declares whether it is single-valued and inheritable. Constraints use the validation protocol but live in the same descriptor metadata store.

 Core must not create parallel metadata storage systems for UI, serialization, diagnostics or domain-specific features.
