The tests required the app list with no room, the running-app queries
for another app ID, sceLncUtilIsAppLaunched for another title, and
sceLncUtilGetAppId (through GetAppIdThrows) for another title to throw.
Those answers aren't measured, and a test shouldn't lock in the
placeholder, so these checks go and GetAppIdThrows is back to main's
form. The calls still refuse those cases, as the debt entries say; the
running title's answers and firmware 13.42's argument checks stay.
BunnyFl ran firmware 13.42's libSceSystemService.sprx in an emulator and
recorded the checks these calls make before they pass a request on. A
null title ID or one whose length isn't 9 makes sceSystemServiceGetAppId
and sceLncUtilGetAppId return -1 and sceLncUtilIsAppLaunched return
0x80940005. A null output, list, count or user returns 0x80940005 from
the LncUtil and SystemService calls and 0x80e30003 from
sceShellCoreUtilGetUserFocus, before the app ID is looked at, and a null
sceLncUtilLoadExec path returns 0x80940005.
What the module passes on as a request still throws: another
9-character title ID, another app ID, a list capacity of 0 and an empty
sceLncUtilLoadExec path.
sceLncUtilIsAppSuspended, sceSystemServiceIsAppSuspended and
sceLncUtilIsSpeculativeLaunch write false for the running title's app
ID. The title that calls them is running and has no shell to suspend
it. It was started from the host rather than by sceLncUtilLaunchApp,
so no LncLaunchParam asked for a speculative launch. Another app ID
and a null output still throw.
sceLncUtilGetAppLaunchedUser, sceSystemServiceGetAppLaunchedUser and
sceShellCoreUtilGetUserFocus write the initial user for the running
title's app ID. That is the user sceUserServiceGetInitialUser and
sceUserServiceGetForegroundUser report. Another app ID and a null user
pointer still throw.
sceLncUtilGetAppId and sceLncUtilIsAppLaunched accept the running
title's ID as sceSystemServiceGetAppId does, and
sceLncUtilGetAppIdOfRunningBigApp returns what
sceSystemServiceGetAppIdOfRunningBigApp returns. Both big-app lists
write the running title's app ID as their only entry, because AnyPS5
runs one title. Another title ID, a null pointer and a list capacity of
0 still throw.
sceSystemServiceShowDisplaySafeAreaSettings returns success without
showing anything, so check the result through the existing guest test.
AI-assisted: yes
Forever Launcher (PPSA99030) imports sceSystemServiceAddLocalProcessForPsmKit
and sceSystemServiceKillLocalProcessForPsmKit and stops at load without
them. AnyPS5 runs one process and starts no other, so both throw without
reading their arguments. The parameters follow the title's own firmware
probes (path, argv and a 0x90-byte parameter block; the kill takes the
returned handle), and the unknown results are recorded as technical debt.

The param is void*, as RommPS declares it. The test also passes a null and an empty URI and a param that must stay untouched, and compares against 0x8002002D itself. The debt entries now say the error is returned for any arguments and that the param layout and the console's argument checks are unknown.
sceSystemServiceLaunchWebBrowser fails with the kernel's EOPNOTSUPP: there is no web browser to open. RommPS PPSA76677 stops on main at this import and shows a QR code instead when the browser does not open.
The export threw, and titles query the system name during startup.
Parameter 6 (the system name) now writes the fixed name "PS5" into a
buffer of at least SYSTEM_SERVICE_MAX_SYSTEM_NAME_LENGTH (65) bytes.
A null buffer or a zero size returns SYSTEM_SERVICE_ERROR_PARAMETER,
as in KytyPS5. Other parameter ids and buffers of 1 to 64 bytes still
throw, because no PS5 source gives their result. guest_system_service
covers the error rows, both throws and the returned name.

sceSystemServiceGetHdrToneMapLuminance was NotImplemented. Titles read
it at startup to set up their HDR tone mapping.
The presenter always outputs through a B8G8R8A8 sRGB-nonlinear swapchain,
so the display range the title has to map into is SDR: the maximum and
full-frame maximum luminance are the 100 cd/m2 SDR reference white and
the minimum is 0. A null output pointer returns
SYSTEM_SERVICE_ERROR_PARAMETER like the other getters here.
