Phase 72 task 72.21.1.6 is implemented by the
Xbox GDK SDK stub contract
and the V2OnlineServices public Xbox API surface. The public bridge is
V2XboxGdkSdkStubBridge. This is an NDA-safe interface stub, not a native GDK
implementation. The boundary guarantee is that proprietary headers and symbols
stay in Restricted/NotForLicensees/Online/PlatformSDK/XboxGDK.

Guard Rails#
The public module only defines stable request, config, and operation-plan shapes. Restricted adapters are named as opaque targets so gameplay code can plan work without including NDA GDK headers.
Plans are only ready when the restricted module is loaded, the build is certification-scoped, an Xbox Live user is signed in, and the platform SDK abstraction route is active. Quick Resume requires serialized session state. Smart Delivery and Game Pass checks fail closed unless entitlement verification succeeds.
Verification#
Run the focused gate with:
python3 V2/ue/Tools/check-v2-xbox-gdk-sdk-stub.py
The checker validates the contract, C++ source declarations, automation spec, CI/Horde wiring, this document, Phase 72 TODO evidence, and the NDA-safe public boundary.
