 # Structive Property Core
 
-The Core is the C++20 header-only structural and managed-property layer of Structive.
+`structive::property_core` describes intrinsic property structure and provides managed read/write, synchronization, traversal, validation metadata and type-erased runtime access.
 
-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.
+Core has no access-control modes. A property only reports its own intrinsic `readable` / `writable` capability. External systems own their own exposure and authorization policy.
 
-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.
+Stored `read_only` properties do not receive lock slots or contribute mutexes, and managed reads use the no-lock fast path.
