The status layout is shadPS4's OrbisGameLiveStreamingStatus2 (72
bytes). Live streaming is not supported, so the call reports that no
stream is on air, with an invalid user id; a null status throws.
Uncharted: Legacy of Thieves Collection (PPSA05684) stopped at sceGameLiveStreamingGetCurrentStatus2.
msync follows FreeBSD 11's kern_msync and vm_map_sync over the guest's
mappings as sceKernelVirtualQuery reports them: the address is rounded
down to the page, a range that wraps and MS_ASYNC with MS_INVALIDATE are
EINVAL, an unmapped start or page is ENOMEM, and length 0 checks the
mapping that holds the address. The guest has no file mappings, so a
successful call has nothing to write back. MS_INVALIDATE on a mapped
range throws, since FreeBSD's EBUSY for mlocked pages needs lock state
that is not tracked.
EVO-PLAYER PPSA99039 v0.11.0 imports it.

The IME panel cannot be open while sceImeOpen is unimplemented, so the
query returns SCE_IME_ERROR_NOT_OPENED and leaves the output untouched,
like sceImeSetCaret, sceImeSetText and sceImeSetTextGeometry. As with
sceImeSetCaret, the closed panel is reported before a null output.

shadPS4 returns success for an object id that was never reserved and the invalid-object error only for a released one; this library returns the error for both.

Both exports are imported by titles that link libSceAudio3d; without them the loader fails with an unresolved import before the title runs. Following the offline model, object attributes are validated but produce no audio and PortFlush drops the frames queued by sceAudio3dPortAdvance.
C17 has no binary prefix: with base 0 or 2, strtol("0b101", &end, base)
reads the subject "0", returns 0 and leaves end at the 'b'. With glibc
2.38 or later, g++ (which defines _GNU_SOURCE) binds std::strtoll,
strtoull, strtoul, strtoimax and strtoumax to the C23 __isoc23_*
functions, which accept 0b/0B: the Linux exports returned 5 and
consumed the whole string. The Windows UCRT already follows C17, so the
same guest call gave different results on the two hosts.
strtol, strtoul, strtoll, strtoull, _Stoull, strtoimax, strtoumax and
_Stoul now return 0 with the end pointer after the '0' when, after
white space and an optional sign, the text starts with 0b or 0B and a
binary digit, in base 0 or 2. Everything else still goes to the host
function. The scanf family's %i has the same glibc behaviour; it is
recorded in TechnicalDebt.

FreeBSD vsyslog logs the complaint with LOG_ERR|LOG_CONS|LOG_PERROR|LOG_PID passed as the priority (0x23), not LOG_ERR.

ps5-opengl (PPSA99005) and ProsperoRadio (PPSA99001) import syslog
from libSceLibcInternal. Messages go to stderr with the priority, and
the format follows FreeBSD's vsyslog: %m expansion, masking of unknown
priority bits, LOG_USER as the default facility, errno preserved.

A title's descriptors are taken as never being terminals: a file or
pipe gets ENOTTY with the termios untouched, a socket gets what its
protocol answers a termios ioctl on FreeBSD (EADDRNOTAVAIL for AF_INET,
EOPNOTSUPP otherwise), and a closed or invalid descriptor EBADF.
tcsetattr gives EINVAL for an action other than TCSANOW, TCSADRAIN or
TCSAFLUSH, with or without TCSASOFT, before anything else, and EFAULT
for a null termios before the descriptor is checked; with TCSASOFT a
null termios throws, where FreeBSD's libc faults copying it. What the
console gives a title as descriptors 0 to 2 is unknown, as recorded in
TechnicalDebt.

LibwuIonIBw registers video out event id 16, which the host never triggers because its VRR state does not change; kP2L8t3j-aM returns 0 without effect.
Keeps this branch's CONTEXT_FULL | CONTEXT_SEGMENTS read, context-first
order and bounded retry in RaiseOn, and adds #1478's ymm save fields to
both deliveries. The test keeps both phase sets; the vectors phase runs
after the continuing, selfing and looping phases and counts their
deliveries. The TechnicalDebt entry about ymm upper halves is dropped,
since #1478 preserves them.

The guest process is assumed to run as root. Under FreeBSD's
sys_seteuid and sys_setegid, id 0 is then accepted without a privilege
check and changes no credential, so both return 0. Any other id would
change the effective credential, which is not modelled, and throws.
Part of #1578.
sceNpEAAccessInitialize and sceNpEAAccessTerminate resolve the NIDs
7CxI50-xlCk and pMxXhNozUX8, which shadPS4 names in np_partner.cpp. The
stubs still throw; only the names and no-argument signatures change.
Use INFINITY and NAN from <cmath> instead of a new <limits> include, and
list the TechnicalDebt entry beside the other NGS2 voice entries, so the
change merges cleanly with the pan, channel map and reverb changes.

The template allocated a fixed 4 KiB of LDS, so kernels with immediate
offsets past it could not run. --lds (Python lds) sets the group segment
size in bytes, up to 64 KiB, with 4096 as the default.

A reverb_size other than the default was accepted and ignored, and below
about 7.5 kHz an allpass length went negative and wrapped to a 16 GB buffer.

Parse legacy decimal, octal and hexadecimal forms before host lookup. Preserve FreeBSD shorthand, whitespace and 64-bit accumulation, clear the SDK resolver error on numeric success, and add regression coverage.
libSceVdecsw is the software H.264 decoder interface PPSA05684 uses for
its movies. Decoder creation, compute queues, memory queries, decode
input and output, AVC picture info, reset and finalize are implemented
with the layouts of shadPS4's vdecsw.h, checked against the title's
movie decoder, and decode through libSceVideodec2. The H.264 stream the
Videodec2 test uses moves to a shared fixture, and a guest test decodes
it through Vdecsw.
Uncharted: Legacy of Thieves Collection (PPSA05684) plays its movies through libSceVdecsw and stopped at sceVdecswQueryComputeMemoryInfo.
llvmpipe builds the high dword of the shader clock with a left shift by
32 (emit_clock in Mesa's lp_bld_nir_soa.c), so it is always 0 and
s_memtime and s_memrealtime wrap every 2^32 ns. A pass of
agc_driver_shader_clock whose two reads straddle a wrap failed with
"memtime: lane N went back from 4294921902 to 3823"; dispatching right
before the boundary fails every lane of that pass.
On llvmpipe compare the low dwords modulo 2^32, which stays correct if
Mesa fixes the shift. Other devices keep the 64-bit comparison.

PS5 titles pass a 0x230-byte SceAvPlayerInitDataEx: auto start is the
byte after debug_level at 0x74, nine 0x30-byte thread parameter blocks
fill 0x78-0x228 and the output video frame buffer count is at 0x228.
sceAvPlayerInitEx read both fields at their PS4 offsets: auto start at
0xa8 is the video decoder thread priority and the buffer count at 0xa4
lies in the audio decoder block. PPSA25063 (Poppy Playtime: Chapter 4)
sets every thread priority to 700, so its intro video started on its
own and stopped at once; it writes auto start 0 and starts playback
itself.
With this_size 0x230 or more both fields are read at the PS5 offsets;
smaller structures are read as before. The layout follows KytyPS5,
prosper, SharpProspero and sharpemu and is recorded in TechnicalDebt.
guest_avplayer builds a 0x230-byte structure with auto start 0 and
nonzero thread parameters, then with auto start 1, and checks when
playback starts and how many video buffers are allocated.

sceHttp2GetMemoryPoolStats, sceSslGetMemoryPoolStats and
sceNetGetMemoryPoolStats threw. PPSA16064 (Minecraft Dungeons II,
Unreal Engine) queries all three while its HTTP module starts, and
aborted there.
Each library now records the pool size given at sceHttp2Init,
sceSslInit or sceNetPoolCreate and reports it with a peak and current
use of 0: the offline Http2 and Ssl models and the host-socket Net
library allocate nothing from these pools. The layouts follow the PS4
SDK's *MemoryPoolStats structures. Net returns EBADF for an unknown
pool and EINVAL for a null output, like its other pool calls; Http2 and
Ssl throw for both, as their error codes are unknown. Terminating a
context or destroying a pool forgets its size.
sceHttp2SetResolveRetry, which the title calls next, accepts and
ignores its value like the other Http2 settings. The four Http2
WebSocket exports the title imports are added as unimplemented.
guest_http2, guest_ssl and guest_sce_net check the reported sizes;
guest_sce_net also checks the null-output and unknown-pool errors.
The unified and service entitlement info list requests and polls threw.
They now return SCE_NP_ERROR_SIGNED_OUT, like the consume requests in
the same library. Their signatures are unknown, so they stay declared
without parameters.
PPSA15657 calls the unified request during start-up and continues past
the error.

Sackboy: A Big Adventure (PPSA01289) imports nine functions that no library
exports, so eager binding fails before it starts.
- libSceVoiceChat: sceVoiceChatRequestLeaveVoiceChatGroup and
sceVoiceChatRequestDeleteVoiceChatGroup, offline requests like the other
sceVoiceChatRequest* calls
- libSceNpSessionSignaling: sceNpSessionSignalingGetConnectionFromPeerAddress,
a throwing stub; the signature is unknown
- libSceCdlgG2P, a new library: the six sceG2PDialog* functions, throwing
stubs declared without parameters
TechnicalDebt records the assumed and unknown signatures.

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.
PPSA01289 (Sackboy: A Big Adventure) calls sceAudioOut2MasteringTerm when it
replaces its world, which threw. Like Init and SetParam it has no effect, as
there is no mastering stage. The title creates its next world's audio device
before it destroys the previous one, so Init runs twice before Term runs
twice; whether the console reports an error for either is unknown, so both
return 0 and the case is recorded in TechnicalDebt.

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.
sceSystemServiceKillApp now ends the title as guest exit() does, so driver calls that wait for the exit park instead of throwing ProcessShutdown, and a second exit waits for the first. The test now fails when the kill returns, exits with a status other than 0 or bypasses the coordinator, and checks why a rejected call throws.
Report an app ID for the running title from sceSystemServiceGetAppIdOfRunningBigApp, and shut the guest down and exit when sceSystemServiceKillApp receives that ID with the arguments -1, 0 and 0. SwanStationPS5 (PPSA98510) 1.0.6 closes itself this way and stops on both imports on main.
The hardware findings give 0xF_F000_0000, which is 0xFF0000000, not 0xFF00000000. Check the ring across threads, at ps5-opengl's size of 0x1b000 and with a canary after the outputs, and say in the debt entry that nothing is written to the ring.
Record the tessellation factor ring that sceAgcDriverSetTFRing receives and report it from sceAgcDriverGetTFRing, with the console's default of 0xFF00000000 and 128 KiB before a title sets one. VITA5 (PPSA39410) and Homebrew UI Lab (PPSA99050) stop on this import once sceVideoOutGetResolutionStatus resolves.
EVO-PLAYER (PPSA99039) creates resident AVC, HEVC and VP9 decoders at
start-up, and stopped at "Videodec2: unsupported codec" on the HEVC one.
Codec types 974921 (HEVC) and 2382845 (VP9) now open FFmpeg's HEVC and
VP9 decoders. HEVC input goes through the same Annex B conversion as
H.264 and VP9 frames are passed through; output stays 8-bit NV12, and a
frame deeper than 8 bits throws. Picture info throws for HEVC and VP9,
whose layouts differ from the AVC one.

Capturing a shader evaluates every V#, T# and S# the program uses,
including those behind a branch the wave does not take. When such a
descriptor was loaded through a pointer read from memory that is null
or unmapped, the capture threw "guest memory is not readable", while
the console faults only if a wave executes that s_load. The descriptor
now reads as zero words, and the flat SRT walk records the s_load's
dwords as it does for flat reads, so their guarded ReadConst raises
the BDA fault where the wave runs the s_load. A zero V# is an absent
buffer and a zero T# binds a null descriptor, as for any zero word
read from memory, so nothing new enters a key. A zeroed descriptor
whose read no flat slot records still throws, as do branch conditions,
uniform fills, table bases and user-data pointers.
Capturing a shader threw "null or misaligned address" when the flat
SRT walk read through a pointer loaded from memory that is null or
unmapped, even when the program skips that s_load. Such a read now
yields zero and a record with its pc and address, as does a slot whose
address needs it. The registered artifact checks one flag word per
guarded slot at each ReadConst; the capture appends the flags and the
records to the flattened SRT, and a set flag raises an Unmapped BDA
fault through the fault buffer and stops the invocation as a BDA read
does. Nothing per capture enters a key: poisoned and clean captures
share one variant and specialization. Descriptors, branch conditions,
uniform fills, table bases and user-data pointers that need such a
value still throw, and poisoned results stay out of the dispatch and
draw caches. The shader disk cache format becomes 21.
