# Structive Property Core

The Core is the C++20 header-only structural and managed-property layer of Structive.

It provides `Type_Descriptor<T>`, `Object_Schema`, member/computed property descriptors, the unified Attribute protocol, explicit constraints and validation, access capability views, synchronization plans/guards, typed traversal and type-erased runtime access.

The core design rule is that registered properties remain ordinary C++ members. Structive adds a managed structural layer; it does not replace the native object model.
