 ### Unknown function info
 
+- [sceNpEntitlementAccessGetEntitlementKey](../../core/libs/prx/libSceNpEntitlementAccess/Export.cpp) - the three-argument signature, 16-byte key and errors `0x817D0002`/`0x817D0007` follow [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/main/src/libs/libNet.cpp); PPSA01521 passes a service label, entitlement label and output pointer. Only the no-key path is implemented: local entitlement labels carry no keys, and the output is untouched on failure. Console error precedence and key provisioning are unverified
+- [sceRudpGetStatus](../../core/libs/prx/libSceRudp/Export.cpp) - PPSA01521 passes an output pointer and byte count `0xF8`; the status layout, size rules and error behavior are unknown. The export throws without writing output, including after initialization. [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/rudp/rudp.cpp) declares it without arguments and returns success without writing status
+- [sceHttpSetCookieEnabled](../../core/libs/prx/libSceHttp/Export.cpp) - the two-argument signature and 0/1 enable values follow [VitaSDK](https://github.com/vitasdk/vita-headers/blob/master/include/psp2/net/http.h) and [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/network/http.cpp); PPSA01521 passes 0 to disable cookies. Disabling succeeds because the offline HTTP backend has no cookie engine; enabling throws. Invalid enable values use the same error as `sceHttpSetInflateGZIPEnabled`. Like the existing offline HTTP setters, the handle is not validated; requests still fail with the network error. Console behavior is unverified
+
 - [sceHmd2Initialize](../../core/libs/prx/libSceHmd2/Export.cpp) (libSceHmd2) - the error the console returns when the PS VR2 runtime is unavailable is unknown; it returns libSceHmd's `UNSUPPORTED_FEATURE` (0x81110016). PPSA01317 passes a pointer to 16 zeroed bytes and only tests the result for non-zero
 - PPSA01317 imports declared without parameters, signatures unknown: the remaining [libSceHmd2](../../core/libs/prx/libSceHmd2/Export.cpp) and [libSceVrTracker2](../../core/libs/prx/libSceVrTracker2/Export.cpp) exports. Names from the aerolib NID list
 - [libSceMbus](../../core/libs/prx/libSceMbus/Export.cpp) (`libSceDeviceService`) - signatures taken from PPSA01317, which calls `sceDeviceServiceInitialize(3, 0)`, polls `sceDeviceServiceGetEventState(1)` and queries again when bit 0 or 1 is set, and calls `sceDeviceServiceQueryDeviceInfo_(0x7001, 0, 0, infos, 1, &count, &unknown, 0x70)`, treating a negative result as an error and `count` as the number of entries. The host has no devices: the event state is 0 and a query returns 0 with `count` 0
