Return SCE_SHARE_PLAY_ERROR_INVALID_ARGS (0x810E0001) instead of throwing APS5_INVALID_ARG_EX when an invalid prohibition value is passed to sceSharePlayProhibitController. Update regression test assertions in GuestSharePlay to verify the error code and record technical debt.
RaiseOn suspends the target, reads its context and, while it is in host
code, resumes it and samples again after SwitchToThread. On a 16-core
Ryzen 9 5950X (Windows 11 22H2) that resampled the writer of
guest_raise_in_host_code about every 10 us before it could run: in the
raise that hung, 4,989 samples over 50 ms all found it in ucrtbase, so
the 50 ms host-code limit ran out and the handler was redirected into
fwrite, where it deadlocked on the stream lock (the test timed out at
30 s on every run). In a passing raise the samples sat at one RIP for
14,695 of 14,703 samples and the raise took 145 ms.
Spin for 20 us before each new host-code sample, so the target gets to
leave host code. With that, guest_raise_in_host_code passes 5 of 5 runs,
no raise is redirected in host code, and the longest raise is 0.46 to
0.53 ms. Other samples keep SwitchToThread.

The debt entry says the rule follows a static reading of the console's
wcsncat_s in libc.prx, that wcscat_s inherits it unread, and that the
narrow strncat_s keeps a wider rule, as asked in review.

Initialize, Terminate, UpdateStatus, GetStatus, Open, OpenA, Close and
GetResult run the common-dialog state machine. There is no PSN profile
UI, so Open and OpenA finish at once and GetResult reports result 0,
userAction USER_CANCELED and the caller's userData, as shadPS4 does when
its window is dismissed.
Paths where shadPS4 and the other common dialogs here return different
errors throw, and so does a param whose size or mode does not match the
shadPS4 layout. The common-dialog codes the library uses are added to
libSceCommonDialog/CommonDialog.hpp.
Every import lookup walked the lease out from the containing range to find
the run of continuing registry ranges, which is linear in the run length.
That walk depends only on the lease snapshot, the containing range and the
import window block, so its first and last index are now memoized per
thread under a weak reference to the snapshot, the range index, the window
and the window's low end. APS5_NO_RUN_MEMO walks every time.
Everything that depends on other state runs on each call as before: the
largest size, the budget, the failed blocks, the remembered refusals and
the halving block search. importRunBounds returns the chosen indices, so
sameRange, runCovers and the whole-run lookup in importAllocation compare
against the lease without copying the run's range pointers.
importRunFailureShrinkTests records a failed 8 MiB block between two
lookups on an unchanged registry and requires the run to shrink to its
4 MiB blocks. importRunGrowthTests and importRunReplacedTests check that a
run grows and shrinks when its ranges are registered or replaced.

Delegate sceNpCommerceDialogInitializeInternal to sceNpCommerceDialogInitialize, sharing dialog state and returning COMMON_DIALOG_ERROR_ALREADY_INITIALIZED on duplicate initialization, following shadPS4. Add regression tests in GuestNpCommerceDialog covering initial, duplicate, and post-termination initialization, and update technical debt documentation.
Adds the PPSA01746 measurements on an RX 6400 to the existing entry: the awaited word already holds a slot address when the wait starts, and the RELEASE_MEM the driver saw was queued but not shown to land.
