Resolve ASCII case differences in guest paths and mount aliases while preferring exact names and rejecting ambiguous fallback matches. Preserve new filenames and host roots. Five filesystem tests pass; Skyrim now loads its INI and shader archives, initializes Vulkan and uploads intro textures instead of dereferencing null shader metadata. Written with AI assistance.
Titles pass handle 0 (RTLD_DEFAULT) for a process-wide lookup, and the loader rejected it: the handle is
not in the module map, so every such lookup failed even when a loaded module exports the symbol. Handle 0
and -2 now take the default scope, searching the global modules by plain name, NID and `#guest` form, and
then the process-wide scope.
The process-wide scope of the real loader also contains glibc and libstdc++, so an unfiltered fallback
would answer `malloc`, `dlopen` and `pthread_create` where PS5 reports the symbol as missing: handle 0 is
the main program, whose lookup sees the program's exports, not the host C++ runtime. A result from the
process scope is therefore accepted only when `dladdr` attributes it to a converted or replacement module
(a `.prx` library or the executable), which keeps the fallback for guest symbols and removes the host
leak. `guest_dynamic_loader` asserts the three host names are not found; disabling the filter makes that
test fail.
The scripting heap that an earlier revision of this branch added has been dropped: the title reaches the
same boot milestone with the lookup failing honestly, so the export was an inference rather than a
requirement, and prosper's bring-up notes report `ESRCH` for that name on hardware.
Preserve files across unmount, block new lookups until remount, and validate mount-dependent operations. Keep prior-run storage inaccessible after initialization.

send, sendto and sendmsg rejected every flag with EOPNOTSUPP, so callers
that pass FreeBSD's MSG_NOSIGNAL (0x20000) could not send at all. Accept
it: Windows sockets never raise SIGPIPE, and on Linux it maps to the
native MSG_NOSIGNAL. Other flags still fail with EOPNOTSUPP.
DOOM (PPSA99666) sends its upload server replies with MSG_NOSIGNAL and
closed every connection without an answer.

Translate the FreeBSD pollfd layout and flags to WSAPoll on Windows and
poll on Linux. Closed socket descriptors report POLLNVAL, a timeout below
-1 fails with EINVAL and a null array with EFAULT. Non-socket
descriptors, unknown event bits, POLLPRI on Windows and an infinite wait
without sockets throw; these are recorded in TechnicalDebt.
DOOM (PPSA99666) imports poll for its upload server.

Guest C built with -fexceptions binds __gcc_personality_v0 to
__gcc_personality_v0_nid_postfix, and the unwinder recognizes the frame
by that address. exception_c_cleanup links the host personality, so it
passed without the export.
The new test builds a call-site table by hand and drives the routine the
way the unwinder does: through the _nid_postfix symbol and through
CallPersonality. It covers the cleanup phase installing the landing pad,
the search phase continuing, ranges before and after the call site, a
call site with no landing pad, no LSDA, a signal frame, an unsupported
version, and an unknown personality. Without the export it fails to link.
No request reaches the network, so sceHttpsSetSslVersion has no TLS
connection to configure, sceHttpSetRedirectCallback and
sceHttpSetCookieRecvCallback register callbacks that are never called,
and sceHttpsGetSslError reports error 0 with detail 0. A null errNum or
detail returns SCE_HTTP_ERROR_INVALID_VALUE like sceHttpGetLastErrno.
Signatures follow shadPS4.

A thread had one TimedWait waiter for every wait. When
sceKernelRaiseException reached a thread blocked in a TimedWait
condition, its handler ran as an APC inside that wait, and a wait in
the handler queued the same waiter on a second condition while it was
still linked into the first. The links of the first queue were
overwritten, so waiters behind it were never woken, and a wake of the
outer wait set the shared event and was consumed by the inner wait.
A wait now takes the thread's first waiter that is not in use, and
creates a deeper one for a wait nested inside another.

On Windows each AIO request seeked a _dup of the descriptor and then read
or wrote through it. A duplicated descriptor shares the file position, and
the seek and the transfer are separate calls, so two threads submitting
requests on one descriptor could transfer at each other's offset. Each
request is now a single ReadFile/WriteFile with an OVERLAPPED offset on
the OS handle, as pread and pwrite already do in Stdio.cpp.
GuestAio reads four distinct blocks of one descriptor from four threads
and checks every result.

Opening a volume needs administrator rights, so the volume flush skipped
every volume in a normal user session. The libc, libkernel, save data and
app content file functions now record each host file and directory they
change. On Windows sceKernelSync flushes the recorded paths that changed
since the previous call, plus their changed parent directories, through
handles a normal user can open. Linux still calls sync().
wcstod, wcstof, wcstold, wcstol, wcstoll, wcstoul, wcstoull, wcscoll and wcsxfrm still forwarded to the host's wchar_t functions, which use 32-bit units on Linux. The wcsto* functions now parse the ASCII prefix of the guest string with the narrow parsers, as the C locale accepts only ASCII white space and digits. wcscoll compares like wcscmp and wcsxfrm copies, as strcoll and strxfrm do in the C locale.
BnMAMrsfVWo is _ZSt19_Throw_bad_weak_ptrv. Replace the unknown stub
with a throw of a guest std::bad_weak_ptr, and add its type info,
vtable, destructors and what().

FreeBSD's setvbuf takes a zero size with _IOFBF or _IOLBF as "pick the
buffer size". The UCRT rejects sizes below 2 for those modes through
its invalid parameter handler, so the call failed on Windows and a test
process was terminated. A zero size now drops the given buffer and
asks the host for one of BUFSIZ bytes.

Gathering every iovec into one host buffer threw for a total above
INT_MAX, which a console readv/writev accepts, and copied the whole
transfer twice. Each iovec is now read or written in place, in chunks
of at most INT_MAX bytes. A readv on a pipe returns after one read so
it does not block once the available bytes are consumed.
