There is no PSN sign-in, so the code getter answers SCE_NP_ERROR_SIGNED_OUT
instead of throwing; its parameters are unknown and not read. Minecraft
(PPSA17221) calls it after its sign-in dialog and treats the result as
offline play. The request, token and wait calls are left to #3604.

FreeBSD's vfs_kqfilter checks neither the vnode type nor fflags, so the
registration is valid; it is only delivered for a move between directories,
which the Windows directory handle cannot tell from a removal plus an addition.
Also moves the TechnicalDebt entries to docs/dev/debt after main split the file.

The trace gets a gpu track: one slice per recorder batch from its timestamp
pair, and with APS5_PROFILE_GPU=1 one per command class range under the
[gputime] class names. The GPU clock is mapped onto the CPU clock from
calibrated timestamps (VK_KHR_calibrated_timestamps or the EXT version,
enabled only when a trace switch is set) taken when the window opens and
when it closes. A traced thread's wait for the GPU mutex becomes a
GpuMutex.wait.<site> slice, and the shader preparation threads are traced
with smaller buffers.

PS5MC (PPSA99420) imports setitimer (hPWDGx8ioXQ, aerolib) at registry
index 472, after tcsetpgrp and before getitimer. Predicted stop:
"FAIL: unresolved ELF import hPWDGx8ioXQ from libkernel.prx".
setitimer follows FreeBSD 11.4 kern_time.c (8c639945) sys_setitimer and
kern_setitimer: EINVAL for an unknown timer and for an itimerfix failure
or more than INT32_MAX / 2 seconds; a zero value clears the interval and
disarms; a null value reads the timer, EFAULT when the output is null too.
ITIMER_REAL shares the alarm state, now with an interval that re-arms it
as realitexpire does; alarm clears it, as FreeBSD's alarm.c does.
Guest SIGALRM handlers are not run, so an expiry with a handler, or with
SIGALRM blocked (signals are never left pending), throws naming the
interval; SIG_IGN drops it and the default disposition exits with 142,
as alarm already did. Intervals below 1 ms throw (itimerfix rounds them
to tick / 16 and the console's hz is unknown). ITIMER_VIRTUAL and
ITIMER_PROF throw when armed and read and disarm as zero.

UFC 6 (PPSA23566) imports sceNetResolverAbort (#992, #1502); Palworld
(PPSA23126) and LEGO Horizon Adventures (PPSA14632) import
sceNetResolverStartNtoaMultipleRecords.
Signatures and behaviour follow shadPS4 811bfcd7d17e
(src/core/libraries/net/net.cpp, net_resolver.cpp); the abort signature
also matches SharpProspero Interop/Net/Socket.cs.
sceNetResolverStartNtoaMultipleRecords shares the lookup of the Ex form
and, like it, throws for any flag. sceNetResolverAbort returns EBADF for
an unknown resolver and throws for flag bits other than NTOA (1) and
ATON (2) preservation. Host lookups cannot be interrupted, so an abort
during a running lookup makes it fail with EINTR when the host call
returns, without writing its output; with nothing running, the
preservation flags make the next lookup of that kind fail with EINTR.

(cherry picked from commit bcc8be8a58aa6a9e6b7c288d8a90af6ed63837aa)
Review of #3787 asked for no retries after an error in Jit.cpp.
Linux: memfd_create is called once with MFD_CLOEXEC. MFD_EXEC was
tried first and dropped on EINVAL; the flag only sets the file's execute
permission bits (Linux 6.3 and later), not whether the object maps
PROT_EXEC, which is decided by the mapping protection, as for the direct
memory memfd in DirectMemory.cpp. A one-shot choice from the headers
would fail on older kernels, so the flag is dropped; TechnicalDebt
records it.
Windows: the delete-on-close backing file is named from the process id,
a process-wide atomic counter and the performance counter, so CREATE_NEW
cannot meet an existing name, and any CreateFileW failure throws with
the Win32 error instead of looping up to 64 times on ERROR_FILE_EXISTS.
The descriptor stays a CRT descriptor on the file, so close, dup and
dup2 keep working as before.

The three JIT shared memory exports (avvJ3J0H0EY, MR221Mwo0Pc,
YKT49TOLQWs) are absent imports of three homebrew titles that cannot
finish loading without them. Predicted next stops (registry order):
- VLC PPSA85300 after getdtablesize (idx 354):
"FAIL: unresolved ELF import YKT49TOLQWs from libkernel.prx"
(Map idx 452, Create idx 462)
- XPSemu PPSA97358 after tcsendbreak (idx 214):
"FAIL: unresolved ELF import avvJ3J0H0EY from libkernel.prx"
(Create idx 398, Map idx 399)
- RetroArch PPSA99169:
"FAIL: unresolved ELF import avvJ3J0H0EY from libkernel.prx"
(Create 476, Alias 477, Map 478)
XPSemu and VLC (ps5/compat/mmap.c, __wrap_mmap) create an object for
every anonymous PROT_EXEC mapping (QEMU's TCG buffer) and map it with
the same protection, falling back to flexible memory on any non-zero
return. RetroArch's eboot runs a probe: Create("ps5-platform-probe",
0x10000, 7, &fd), Alias(fd, 3, &alias), Map(fd, 5, &address), then logs
"jit create=0x%08x alias=0x%08x map=0x%08x".
Signatures from Orbital cc408367 tools/ida/db_types.json (name, len,
maxProt, fdOut; fd, maxProt, fdOut; fd, prot, startOut), matching
ps4sdk 4df9d001 include/sce/kernel.h, ps5-jar-loader 8034177e
LibKernel.java and the three titles' call sites. SharpProspero 5dfdb4b0
declares the alias as returning the descriptor; the RetroArch call site
passes an out pointer.
The object is a host anonymous file (memfd on Linux, a delete-on-close
temporary file mapped as a PAGE_EXECUTE_READWRITE section on Windows),
the alias a duplicate descriptor, and each map maps the whole object
through the direct memory placement path, so a write through one view
is visible through the others. Bad lengths and protection bits are
EINVAL, protection past the descriptor's maximum is EACCES (FreeBSD 11
vm_map_protect), unknown descriptors are EBADF; close, dup and dup2
keep the descriptor table in step. Unverified details are recorded in
TechnicalDebt.

PRAGMATA (PPSA02530) imports sceSharePlayProhibitController (NID
FzQS6DREDfk), which no library exports on main, so the load fails on the
unresolved import. It is one of the "six declared-only imports" of
xXPBSXx's branch in #3043 (comment 6107100345): "These only stop the
load failure; as described above, the title calls some of them later and
needs their real behavior."
sharpemu src/SharpEmu.Libs/Share/SharePlayExports.cs:9-31
(a2983692930564815a77f81e74c151268f5b935f, used as a source of facts)
takes one value, accepts 0 and 1 and returns 0. Nothing here would read
the setting, as no Share Play session or visitor controller exists, so
it is not stored. sharpemu rejects other values with its synthetic
0x80020003, not a Share Play code, so they throw, as
sceSharePlayInitialize does for its unknown error. Like the other exports
of the library it does not check initialization. The NID hashes from the
name and is in aerolib. Unverified points are in TechnicalDebt.

PRAGMATA (PPSA02530) imports sceRazorCpuSync (NID Ax7NjOzctIM), which no
library exports on main, so the load fails on the unresolved import. The
title calls it after sceConvertKeycodeGetCharacter. From #3043 (comment
6106731532): "`sceRazorCpuSync`: answering 0 and doing nothing was
enough to carry on (the other `sceRazorCpu*` calls in `main` are no-ops
without a capture)."
SharpProspero src/SharpProspero/Interop/Debug/RazorCpu.cs:119-122
(5dfdb4b0b166e83dc9ae275001afb695f12c7174, GPL-3.0, used as a source of
facts) gives int sceRazorCpuSync(void), an unnamed frame-boundary event.
Without a capture there is no event to record, so it returns 0 and does
nothing, like the other sceRazorCpu markers here and the shadPS4 stub
(razor_cpu.cpp:143, 3a9f57265d28975658f1ca941daa5c879c7a74bd). The NID
hashes from the name and is in aerolib. Unverified points are in
TechnicalDebt.

PRAGMATA (PPSA02530) calls it after sceRazorCpuSync and stops on main
with "sceNpEntitlementAccessGetGameTrialsFlag not implemented". From
called once; I logged four register values but cannot tell which are
arguments. Answering 0 without writing anything carried on." Killing
Floor 3 (PPSA08427) and RE4 also import it.
The title is reported as a full game, not a game trial: 0 is written to
the uint32_t output and 0 returned; a null pointer returns 0x817D0002.
Signature, value, one-word write and error follow sharpemu
src/SharpEmu.Libs/Np/NpEntitlementAccessExports.cs:98-116 and its test
NpEntitlementAccessExportsTests.cs:16-36 (a2983692930564815a77f81e74c151268f5b935f),
used as a source of facts; 0x817D0002 is also the parameter error of
KytyPS5, prosper and sceNpEntitlementAccessGetEntitlementKey here. The
library has no initialization state, so none is checked. The NID
y7JD1gfwyfA hashes from the name and is in aerolib. Unverified points
are in TechnicalDebt.

Adds tcsendbreak (vXE-dIUIZlE), tcdrain (brGGJWsZauw), tcflush
(FxHW5NuEXsY), tcflow (OG8xRaGIpqk), tcgetpgrp (5OEl1mRhUm0) and
tcsetpgrp (YMuesZTyTl4) next to tcgetattr and tcsetattr in
File/src/Terminal.cpp. The NIDs come from tools/nid_names.py and match
aerolib.csv (zecoxao/sce_symbols 2883963a).
They follow FreeBSD 11.4 lib/libc/gen/termios.c (8c639945), which
implements each one over a terminal ioctl: tcflush returns EINVAL for a
queue other than TCIFLUSH, TCOFLUSH or TCIOFLUSH and tcflow for an
action outside TCOOFF..TCION before the descriptor is used; every other
call fails with the error the merged tcgetattr gives (EBADF for a closed
descriptor, ENOTTY for a file or pipe, EADDRNOTAVAIL or EOPNOTSUPP for a
socket, per soo_ioctl and in_control/in6_control). tcsendbreak fails on
TIOCSBRK before its 0.4 s pause, and tcflow's TCIOFF/TCION fail in
tcgetattr. FreeBSD's pipe_ioctl answers TIOCGPGRP/TIOCSPGRP on a pipe or
FIFO with the SIGIO owner, which is not modelled, so tcgetpgrp and
tcsetpgrp throw on a host pipe above descriptor 2.
Titles (homebrew catalog #1578), predicted stops from registry order:
- PS5MC PPSA99420 imports tcsendbreak (442), tcdrain (443), tcflush
(444), tcflow (445), tcgetpgrp (462) and tcsetpgrp (463); once pause
and setrlimit are in, it stops at
"FAIL: unresolved ELF import vXE-dIUIZlE from libkernel.prx".
- XPSemu PPSA97358 imports tcsendbreak (214), its first uncovered import
after execv, sigwait, setrlimit, mlockall, setuid and getopt:
"FAIL: unresolved ELF import vXE-dIUIZlE from libkernel.prx".
guest_terminal covers each call over stdin, stdout, stderr, a file, both
pipe ends and an AF_INET socket, the EINVAL cases (also on -1), and
EBADF for -1, a closed socket, a closed pipe and a closed file.
