A raised exception redirects the target thread to a stub that runs the handler and returns through RtlRestoreContext. On Windows 10 (19045) RtlRestoreContext restores in user mode only when the context flags are exactly CONTEXT_FULL | CONTEXT_SEGMENTS (CONTEXT_XSTATE aside); for the CONTEXT_FULL | CONTEXT_FLOATING_POINT context it was given, it calls NtContinue. When the next raise suspended the thread inside that system call, NtContinue then replaced the redirected context with the one it was restoring, so the handler never ran although sceKernelRaiseException had returned 0. guest_raise_exception lost such a delivery to its busy thread in about one run in five and hung until the ctest timeout.
The context is now read with CONTEXT_SEGMENTS, so the handler returns through the user-mode restore, and a raise that finds the thread inside NtContinue or NtContinueEx (an APC or an exception handler returning) resumes it and suspends it again.

Measured on a PS5 (firmware 13.60) through dlopen of
libSceVoiceQoS.sprx: a null block, any size other than exactly 0x40000,
and an app type other than 0x20000000 or 0x10000000 all return
0x804E0902 without touching the block, instead of throwing. A second
initialization returns 0x804E0905, as prosper reads from the module.

Add scePadOpenExt for special ports, which return DEVICE_NOT_CONNECTED because the host has no special controller, and the extended read and report exports, which throw.
The LOD warning lwe adds to the texel status is texture-streaming feedback,
which is not reported for the T# MIN_LOD_WARN either. Accept lwe on sample
and gather instructions as it already is on loads and stores; lwe on
image_get_lod still throws.
Once an image has .ehmeta, an eh_frame_hdr version other than 1, an
eh_frame_ptr encoding other than absptr or pcrel, a 64-bit record length,
an eh_frame_ptr outside the image or a missing terminator now throw
instead of returning the empty answer. The test queries a fixture DLL
whose .ehmeta it can break, since the unwinder reads the same section.

Opening a save progress dialog immediately reported FINISHED. Skyrim
waited for RUNNING before writing SAVEDATA.DAT and never resumed. Keep
progress-bar mode running through polling and progress updates until
Close, retaining the existing automatic responses for other dialog modes.
Add lifecycle regression coverage for repeated polling, completion,
reopening, result metadata and ordinary selection dialogs. The test
failed on the previous implementation and passes with the fix on Fedora
44 Release. Correcting the live dialog state recovered a blocked Skyrim
save without restarting its session.

Measured on a PS5 (firmware 13.60) through dlopen of libSceRtc.sprx.
The weekday is required in any case or length, month names may be
full, RFC 2822 and RFC 850 share one lenient grammar with 2-digit years
split at 50, and the asctime zone is ignored. Zones come from a name
table, a military letter, or +HHMM without a range check. Text the
console rejects returns a parse error with the tick untouched, and an
invalid calendar date returns 0 with only the offset applied to the
tick, as the console does.

On a PS5 (firmware 13.60) every input that starts with a digit gets the
same result and tick from sceRtcParseDateTime as from
sceRtcParseRFC3339, except that leading spaces and tabs are skipped
first. A string without a zone, or with a space instead of T, is a
parse error rather than UTC.

A year before 1980 or after 2107 cannot be packed into the DOS time, so
GetDosTime threw. Following the disassembly-derived fpPS4
reimplementation of the PS4 library, it now returns INVALID_YEAR after
writing 0 for an earlier year and 0xff9fbf7d, the largest encodable
time, for a later one. The TechnicalDebt entry now records fpPS4 as the
source for the SetDosTime year decode as well.
A captured grain stored only the port slot and data pointer, so a port
created in a destroyed port's slot before the next push mixed the old
pointer with its own format. Ports now carry a generation that the
capture records. TechnicalDebt notes that the last grain pushed before a
title stops is never played.

A wave64 graphics program on a 32-lane host runs one guest lane per
invocation, yet an EXEC written as a value keeps all 64 bits: the NGG
prologue's s_lshr_b64 exec, -1, 64 - count reads count 0 and sets -1.
A waterfall loop that copies EXEC with s_mov_b64 and retires one key
per pass then never empties its copy, since no ballot sets the lanes
the host lacks, and its v_readlane picks lane 32 and up.
readRawU32 now ANDs EXEC with a ballot of true when it is read as a
value (s_mov_b64, ALU sources, src_execz), and s_*_saveexec and
s_*_wrexec store that masked copy. EXEC's own words, threadBit and the
saveexec combination keep the raw words, so s_orn2_saveexec_b64 vcc,
exec still sets all 64 bits. On subgroups under 32 lanes the EXEC_LO
copies of agc_driver_scalar_sop1 now hold only the subgroup's lanes.
The Smurfs Dreams imports both and no library exports them, so eager
binding stops the title before it starts. sceAudioInAsyncOpen throws
like the other AudioIn opens that have no implementation;
sceHttp2SetMinSslVersion returns success like the other Http2 SSL
setters, as no request reaches the network.

The host mixes without the console's mastering stage, so the mastering
parameters have nothing to configure, as with sceAudioOut2MasteringInit.
Accept them instead of aborting, keep throwing for a null parameter
block, and record SetParam next to MasteringInit in TechnicalDebt.

Return the id a graphics event was registered with in
sceAgcDriverAddEqEvent, which titles derive from their context
(PPSA12544: 0 or 1 for graphics, 0x20 + 8 * pipe + queue for compute) and
read back to dispatch the event. Other event filters, a null or
misaligned event and an id above 32 bits throw. The meaning is an
assumption and recorded in the technical debt.

GuestAppContent now writes a param.json that declares downloadDataSize 0
and checks that sceAppContentDownloadDataGetAvailableSpaceKb returns OK
with 0 KB for /download0 (it threw before), and PARAMETER for a null
result. TechnicalDebt records that the console's behaviour for such a
title is unverified.

Address review: read a grain's buffers at the next push without spinning
under the context lock, keep the no-device model mixing at push time,
size the pad queue from the unplayed main grains again, use generic
names in comments and TechnicalDebt, and add audio_out2_timing (next-push
read, queue level beyond the cushion, priming after running dry).

The APC delivery was allocated after SuspendThread, so a target holding
the allocator lock deadlocked the raising thread; it is now allocated
before the suspend. The wait count a raise checks lived in the target's
thread_local storage and dangled once the thread exited; it is now a
member of PthreadPrivate, which TimedWait counts into through a
thread-local pointer bound when the thread starts, and a raise on a
thread that already finished returns ESRCH. TechnicalDebt gets one line
per unverified choice: Windows only, the FreeBSD ucontext layout, the
signal mask, the YMM upper halves, and delivery to threads outside
TimedWait.
