The search returned saves in host directory order and ignored the condition's key and order. A title that asks for the newest save first (modification time, descending) got whichever directory the host listed first: the alphabetically first on NTFS, an arbitrary one on Linux. Sort by directory name, user parameter or modification time, reverse for a descending order, and reject unknown keys and orders with the parameter error, as shadPS4 does.
PPSA06888 stops on main at start-up because its bundled
Media/Plugins/SceRudp.prx imports sceRudpEnableInternalIOThread2,
sceRudpGetOption and sceRudpGetRemoteInfo, which no library exports.
The signatures are unknown, so they are declared without parameters and
throw. The title does not call them during start-up.

Add thirteen offsets measured repeatedly on PS5 firmware 13.42, keeping DST names ahead of their shorter prefixes. Cover case folding, prefix matching and a second valid date.
Written with AI assistance; validated against real hardware and the guest RTC tests.
One queue for APR and AMM buffers kept an AMM buffer behind an APR buffer
waiting on an address that the AMM buffer writes, so neither ran.
Marvel's Wolverine does this: an APR buffer waits on a counter that the
WriteAddress commands of later AMM buffers advance, and its loading
stopped. APR and AMM buffers now keep their order within their own queue.

sceKernelGetModuleInfoFromAddr has a Windows path since 77ef75c1d, so
_sceLibcInternalForceTlsDestructor finds each dso's module there too.
The test takes the other module's address with GetProcAddress where
Linux uses dlsym(RTLD_NEXT), and the TechnicalDebt entry no longer says
the call throws on Windows.

A rect-list draw whose count is not a multiple of 3 threw "incomplete rect-list
primitive". Rect lists are drawn as patch lists of 3 control points, and Vulkan
generates floor(vertexCount/3) patches, so the draw now records as is and the
trailing 1 or 2 vertices are left out. Palworld (PPSA23126) draws 4 vertices x 9
instances as a rect list when character creation opens (#3832).

scePadOpen returned the standard pad's handle for a special port
(type 2) as well, and scePadGetHandle found it there. Both ports then
read the one input queue, so a press queued between two frames could be
drained by the special port's read and never reach the standard port.
PPSA16827 (Harmony's Odyssey) opens both ports for the initial user and
reads both every frame, also polling controller information and device
class data for the special one.
Special ports now return DEVICE_NOT_CONNECTED (0x80920007) from
scePadOpen, as scePadOpenExt already does because the host has no
special controller, and scePadGetHandle has no handle for them.
TechnicalDebt's scePadOpenExt entry now covers both calls.
guest_pad opens a special port before and after the standard one and
expects DEVICE_NOT_CONNECTED, and DEVICE_NO_HANDLE from scePadGetHandle
for the special port while the standard handle stays valid. It fails on
main.
PPSA16827 over 130 s of its title screen: 6812 scePadRead, 3408
scePadGetControllerInformation and 3406 scePadDeviceClassParseData calls
before, two reads of the same queue per frame; 2702 reads, one
information call and no parse calls after.
Elden Ring Nightreign (PPSA25380) imports the function, which no library
exported, so the title failed to load. The option is ORed into the buffer
attribute and a null attribute throws. Options other than 0 and 8 still
throw when the buffers are registered.
`v_movrels_b32`, `v_movreld_b32`, `v_movrelsd_b32`, `v_movrelsd_2_b32`
and `v_swaprel_b32` lowered to a compare-and-select chain over every
register from the base to the program's last allocated register, so a
program addressing 154 registers 104 times turned 3176 ISA words into
649,515 SPIR-V words that Intel's compiler did not finish. The registers
from the lowest relative base up now live in a function-scope array per
invocation (`LoadVectorWindow`/`StoreVectorWindow`), so an indexed access
is one load or store; plain accesses to those registers go through the
same array, DPP-modified relative writes keep their `DppUpdateU32` merge,
an index past the window reads 0 and drops its write, and programs
without relative addressing are unchanged. The same program recompiles
to 392,333 words with 4,992 selects instead of 32,383.

mingw's fprintf writes an unbuffered stream a character at a time and
holds the stream's lock for the whole line. The APS5_LOG_* lines that
carry a RecompileRequest ("Shader ... could not be prepared after
registration", 15-20 KB each) took one WriteFile per character, and every
other thread writing to stderr waited behind them, guest calls that log
included. Demon's Souls (PPSA01342 v1.005, Windows) stops on a black
screen after two frames on main: a BPE job worker waits for the stderr
lock in sceSaveDataDirNameSearch's trace while the shader preparation
pool prints its dumps, so GameCoreLoop never finishes a frame.
The log macros now format the line into memory and write it with one
fwrite, as Driver::reportSkip does since 8cf2f6580. The UCRT writes an
unbuffered stream's fwrite as one even-length block and the last byte,
so a line takes at most two writes on Windows and one on Linux.

sceKernelGetOperationMode returned 0 for both values, which were
unknown. A payload on a PS5 (firmware 13.60) reads mode 2 and submode 0;
nothing past the two ints is written and the result register holds no
status, so the function now returns nothing. PPSA12544 logs both values
and ignores the result.

Hollow Knight Silksong (PPSA12544) imports libSceAgc NID vieBRwlh1Lw
(#699). Its name is unknown: it is not in aerolib, and the
sceAgcUpdateInterpolantMapping label other projects give it hashes to
SbuY2jN+axQ.
OpenAGC (src/game_compat.c at 3c7e807, sceAgcUnknownVieBRwlh1Lw) reads
it from FW 11.60 as the dbOlWdppb4o transform with the same (regs, gs,
ps) arguments, without the identity tail: it writes one register per
pixel shader input, none for a pixel shader without inputs, and rejects
a null pixel shader. It now shares the dbOlWdppb4o path and throws for
the rejected arguments.
For is_f16 1 and 3 inputs whose default_value and default_value_hi
differ, OpenAGC takes DEFAULT_VAL from default_value_hi, while KytyPS5,
sharpemu and dbOlWdppb4o here take it from default_value; these inputs
throw. On every other input the dbOlWdppb4o values equal OpenAGC's.
agc_interpolant_mapping runs the dbOlWdppb4o vectors and OpenAGC's
enhanced-mapping vectors through it.

agc_driver_f32_denormal_flush fails on RADV RENOIR (Mesa 26.2.4):
lane 20 no float mode v_fma_f32 v14, v4, v5, v6 is 0x00800000, expected 0x00ffffff
The driver lowers Fma to a multiply and an add: the compiled shader has
v_mad_f32 and no v_fma_f32. The product 0x1fffffff * 0x1fffffff is below
2^-126 and is flushed before 0x00800000 is added. Lane 20 is the only
row with a tiny product and a non-zero addend. v_fma_f32 and v_fmac_f32
fail on it in all three float modes; every other check passes.
When both return that sum, the two values are not checked. FmaRounding
already leaves out its fused forms on a device that splits fma.
sceKernelGetModuleInfoFromAddr found the size of the image's .eh_frame
on every call by walking all of its CIE and FDE records, checking each
against every PT_LOAD header. The guest libc's unwinder calls it for
each frame it unwinds, so a title that unwinds often walked its whole
.eh_frame hundreds of times per second.
The tables read from a .eh_frame_hdr are now kept per header address
and reused while the image stays loaded. The cache is dropped whenever
dl_iterate_phdr reports that an object was unloaded (dlpi_subs), so an
address reused by another image is read again.
guest_module_info queries a module twice and expects the same tables,
then unloads it, loads it again and expects tables of the same size at
the same offset in the new image.
PPSA16827 (Harmony's Odyssey), title screen, over 500 calls per second
counted under gdb, which slows the title: the process used 9269 CPU
samples per 10 s, 53.7% of them in this walk, and 3306 with this change,
3.2% in the lookup. The title still runs at 27 FPS; its frame rate is
limited elsewhere.
Rows that run the same kernel at the same wave size compile the same
pipeline, so each part now takes whole groups of them, and the test is
split into fourteen parts. Each shader is compiled once per CI run
instead of in up to three parts at once.

On main asin(2.0) returns 0x7ff8000000000000 and sets errno to 33;
FreeBSD msun (lib/msun/src/e_asin.c) returns 0xfff8000000000000 and
never sets errno. asin now handles |x| > 1 itself with quiet
comparisons, so a NaN input still raises no exception. For |x| <= 1
and for NaN the host function is still called.

Surround Sound Studio (PPSA99051), catalog build on main a11c8f7f with
the flat-interpolation fix, stops 16 s in, before its first frame
(orishamir, #3581 comment 6109839314):
sceAudioOutSysGetHdmiMonitorInfo not implemented
The call takes (type, out, size); out must be non-null, size exactly
0x180 and type 1 (HDMI) or 0x10 (sainsaji/PS5-Audio-Passthrough-Research
c3be9c2a, docs/FINDINGS.md section 3 and AGENTS.md:25, firmware 12.70).
Titles read the monitor name at +0x0B, the descriptor count at +0x94 and
8-byte descriptors from +0x98 (same, FINDINGS.md hardware log item 1 and
sample-app/src/platform/ps5/bitstream_out.cpp:92-128).
Audio reaches the host through SDL as PCM and there is no EDID, so type 1
with a 0x180-byte buffer reports a sink without a name or descriptors:
the buffer is zeroed and 0 is returned. Surround Sound Studio's
Passthrough page then lists no formats; EVO Player's code treats an empty
list like a negative return. A null buffer returns 0x80260004, as the
other AudioOut calls do. Type 0x10, other types and other sizes throw:
their results and error codes are not known.

v_cvt_i16_f16 with mul:2, mul:4, div:2 or clamp in the VOP3 encoding
stops the recompiler with "VOP3 source modifiers are not implemented".
On gfx1036 (Radeon 610M) the result is identical with and without
mul:2, mul:4, div:2 and clamp combined with mul:2, for all 66 measured
inputs; clamp on its own is not a measured case.
The decoder now accepts omod and clamp on v_cvt_i16_f16 and drops them,
as measured. Clamp without an output multiplier is accepted by the same
rule: clamp with mul:2 gives the same hardware result as mul:2 alone.
Matches 528 of 528 rows in two float modes, 0 differing.
v_cvt_u16_f16 is not measured and stays refused.
