 ### Silent stubs
 
 - [sceNpGameIntentVshInitialize, sceNpGameIntentVshTerminate](../../../core/libs/prx/libSceNpGameIntent/Export.cpp) (libSceNpGameIntent) - VSH initialization and termination return 0 without performing shell operations, matching `sceNpGameIntentInitialize` and `sceNpGameIntentTerminate`
+- [sceNpAppLauncherInitialize, sceNpAppLauncherTerminate](../../../core/libs/prx/libSceNpGameIntent/Export.cpp) (libSceNpGameIntent) - app-launcher lifecycle returns success without tracking launch state; `sceNpAppLauncherInitialize` accepts its init parameter without validation, following the silent-stub precedent of `sceNpGameIntentInitialize` — a title calls it early in boot, and returning success lets it continue
 
 ### Unknown function info

They are declared without parameters solely to resolve known imports and make no ABI claim.

Call sites in a title's executable give a partial prototype: `sceNpAppLauncherLaunchApp` takes `(user_id, uri struct, context)` and returns int — throws because no launcher-service semantics are derivable. The rest are declared without parameters solely to resolve known imports and make no ABI claim.
