### Functional
- [sceNetSendmsg and sceNetRecvmsg](../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) copy the scatter/gather list through one host buffer and accept only the flags `sceNetSend`/`sceNetRecv` accept. Sending control data throws; a receive never returns control data (`msg_controllen` 0), since no socket option that queues it is supported
- [Additional content](../../core/libs/prx/libSceAppContent/Export.cpp) (libSceAppContent) is not installed or mounted: `sceAppContentAddcontMount` answers `NOT_FOUND` for every entitlement label and `sceAppContentAddcontUnmount` for every mount point, as no add-content mount is ever handed out
- [Additional content](../../core/libs/prx/libSceAppContent/Export.cpp) (libSceAppContent) is not installed or mounted: `sceAppContentAddcontMount` answers `NOT_FOUND` for every entitlement label and `sceAppContentAddcontUnmount` for every mount point, as no add-content mount is ever handed out; `sceAppContentGetAddcontInfo` answers `DRM_NO_ENTITLEMENT` for every label and `sceAppContentGetAddcontInfoList` reports 0 entries
- [sceKernelInstallExceptionHandler](../../core/libs/prx/libkernel/System/src/Exception.cpp) records the handler but nothing delivers to it: a host fault still ends the process, and `sceKernelRaiseException` is not implemented. PPSA12544's PS5Util module (Unity) installs a SIGUSR1 handler that reads `uc_mcontext.mc_rsp` (offset 0xf8 of the context) and raises SIGUSR1 on other threads to stop them for garbage collection, so delivery must run the handler on the target thread with a FreeBSD `ucontext`
- [libSceUlt queues](../../core/libs/prx/libSceUlt/Export.cpp) use preallocated host storage instead of the supplied guest work area; its existing size formula and the 512-byte object layouts remain unverified. Waiting-queue pool thread limits and waiter priority ordering are not implemented. Finalization wakes blocked queue callers with `ULT_ERROR_STATE`.
- [Thread cancellation](../../core/libs/prx/libkernel/Pthread/src/Thread.cpp) (libkernel) is not modelled: `scePthreadCancel` throws, so no cancel request is ever pending and `scePthreadTestcancel` and `pthread_testcancel` return without acting; the cancel state and type set by `scePthreadSetcancelstate` and `scePthreadSetcanceltype` are stored and not used
