# libSceNpCppWebApi technical debt ### Silent stubs - [sce::Np::CppWebApi::Common](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - the `finish` overrides of `TransactionBase<...>` (8 instantiations), `DownStreamTransaction<...>` (2 instantiations) and `Vector>::pushBack` return success without doing work; a failed request never produces a transaction to finish - [sce::Np::CppWebApi::Leaderboards::V1](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - request-body and parameter bookkeeping succeeds without storing state: `GetRankingRequestBody::set{StartSerialRank,Group,Limit,Users,Offset}`, `RecordScoreRequestBody::set{Comment,SmallData,NeedsTmpRank,ComparedDateTime,PcId}`, `User::{setAccountId,setPcId}`, `BoardsApi::ParameterToGetBoardDefinition::{initialize,terminate}`, `RecordApi::ParameterToRecordLargeData::{initialize,terminate}`, `RecordApi::ParameterToRecordScore::{initialize,setxPsnAtomicOperation,terminate}`, `ViewApi::ParameterToGetLargeDataByObjectId::{initialize,terminate}`, `ViewApi::ParameterToGetRanking::{initialize,setgetRankingRequestBody,terminate}` - [sce::Np::CppWebApi::SessionManager::V1](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - parameter bookkeeping succeeds without storing state: `PlayerSessionsApi::ParameterToCreatePlayerSessions::{ctor,dtor,initialize}`, `PlayerSessionsApi::ParameterToGetPlayerSessionInvitations::{ctor,dtor,initialize,setfields,setinvitationInvalidFilter}`, `PlayerSessionsApi::ParameterToJoinPlayerSessionAsPlayer::{ctor,dtor,initialize,terminate}`, `PlayerSessionsApi::ParameterToLeavePlayerSession::{ctor,dtor,initialize}`, `RequestPlayerSession::set{MaxSpectators,InvitableUserType,JoinableUserType,ExclusiveLeaderPrivileges}`, `RequestPlayerSessionPlayer::setPushContexts` - [sce::Np::CppWebApi::TitleCloudStorage::V1](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - `DataApi::ParameterToDownloadData::{initialize,terminate}` succeed without storing state ### Unknown function info - [sce::Np::CppWebApi](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - every request entry point (API calls, transaction `start`/`getResponse`/`readData`, the `*Factory::create`s) returns `SCE_NP_WEBAPI_ERROR_NOT_SIGNED_IN` offline. The constant's name and value follow the reference tables in shadPS4 `np_error.h` and fpPS4 `np_error.pas`, where `0x80552907` is `ORBIS_NP_WEBAPI_ERROR_NOT_SIGNED_IN` and `0x80552901` is `OUT_OF_MEMORY` (no `UNAVAILABLE` exists in the `0x80552901`-`0x8055291F` range); it is the code a signed-out console returns from these entry points. The earlier `0x80552901` value came from the module the previous implementation shipped, which used the same incorrect constant - [sce::Np::CppWebApi::Common::IntrusivePtr](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - the 0x18-byte layout (object, deleter, `LibContext*`) and the offset of the 32-bit reference count in the pointee (0x00, 0x30 for `Vector`) come from the module bundled with one title (PPSA21564); other SDK versions are not checked. The destructor throws on the last reference of a pointer without a deleter: destroying the object needs its destructor and the `LibContext` allocator, which are not implemented - [sce::Np::CppWebApi::Common::String](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - the 0x20-byte layout (32-bit reference count, buffer at 0x08, buffer size at 0x10, `LibContext*` at 0x18) comes from the module bundled with one title (PPSA21564); other SDK versions are not checked. `append` grows the buffer with the host allocator and the destructor frees it, instead of going through the `LibContext` allocator. `pushBack` into `Vector` stores a deep copy, so a destroyed temporary cannot invalidate the stored element; a title that byte-copies a `String` with a live buffer would still double-free, as nothing increments the reference count - [sce::Np::CppWebApi::Common::Vector](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - imported by PPSA03671, whose dump ships no `libSceNpCppWebApi.prx`. A `Vector` handle is an `IntrusivePtr` over a shared body; bodies created by `pushBack` use a host-side layout with the reference count at 0x30, matching the adopted-body convention measured on PPSA21564. The pointer/deleter constructor adopts a title-provided body released through the stored deleter; `pushBack` on such a body throws, since its element layout is unknown. `begin`, `end`, iterators and `operator[]` throw: the only `Vector`s the title reads back come from failed transactions, which never produce one - [sce::Np::CppWebApi::SessionManager2V1](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - imported by PPSA03671. Offline, the factories, `PlayerSessionsApi` calls and transaction `start`/`getResponse`/`readData` fail with `SCE_NP_WEBAPI_ERROR_NOT_SIGNED_IN`; parameter setters, `initialize`, `terminate`, constructors and destructors succeed without keeping state, as no request is ever sent. Response-body accessors (`getSessionId`, `getPlayerSessions`, `getInvitations`, the `IsSet` queries) throw: a failed request never produces a response object - [libSceNpCppWebApi](../../../core/libs/prx/libSceNpCppWebApi/Export.cpp) (libSceNpCppWebApi) - unimplemented stubs have their parameter lists, const qualifiers and return types aligned with the demangled symbols confirmed by NID matching in [#8143](https://github.com/boykopovar/AnyPS5/issues/8143). They cover response-body accessors, iterators, and uninstantiated transactions in Leaderboards::V1, SessionManager::V1, InGameCatalog::V5, TitleCloudStorage::V1, and Common templates: each mangled name gives the method and parameter types, but the runtime layout of response objects and errors are unverified on console, so each call continues to throw NotImplemented_nid_no_patch. No call site is recorded for them
