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.

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.

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.

PPSA03306 (Silt) loads the Unity plugin Media/Plugins/PSNCore.prx, which
imports scePlayerReviewDialogInitialize, Open, UpdateStatus, GetResult and
Terminate from libSceCdlgPlayerReview. No library provided it, so loading
the plugin failed with "Failed to load module ...\libs\libSceCdlgPlayerReview.prx".
The library follows libSceWebBrowserDialog: the dialog shows nothing, Open
finishes at once and GetResult reports that the user canceled. Terminate
also accepts a finished dialog. GetStatus and Close are added as well.
