swscanf (HNnWdT43ues) runs the swscanf_s scanner without the buffer
size arguments after %s, %c and %[, as FreeBSD's swscanf.c passes its
arguments to vswscanf. Both entry points share one engine with a flag
for the sizes; swscanf_s behaves as before.
Title: PS5CEMU-HAR PPSA99360 imports swscanf from libSceLibcInternal.prx
(import audit with --trap-sdk-syscall-stubs, registry index 292, right
after pthread_setaffinity_np at 276). Predicted stop line once
pthread_setaffinity_np resolves, without this change:
FAIL: unresolved ELF import HNnWdT43ues (swscanf) from libSceLibcInternal.prx
NID from tools/nid_names.py, confirmed in shadPS4 aerolib.inl:51950
(e0a466753a1a). Prototype in ps5-payload-dev include/freebsd/wchar.h:133,
export in sce_stubs/libSceLibcInternal.c:8582 (f5d40f02770e).

PS5MC (PPSA99420, Kodi 22) imports getpriority (miQ1wVwSexE) from
libkernel.prx, one reference, next to chflags in its import order.
Predicted stop once the imports ahead of it are covered (not a run):
FAIL: unresolved ELF import miQ1wVwSexE from libkernel.prx
The NID is computed with tools/nid_names.py and matches aerolib.
Follows FreeBSD 11.4 sys/kern/kern_resource.c sys_getpriority
(8c639945a44588f6cfdddfb057bb5aad88735da0) for the only guest process,
taken to run at nice 0 and to lead its own process group (as kill and
setsid already assume): PRIO_PROCESS and PRIO_PGRP with 0 or its pid,
and PRIO_USER with 0 or its uid 0, return 0; other ids give ESRCH and
an unknown which gives EINVAL. getpriority is a bare system call in
FreeBSD's libc (lib/libc/sys/Symbol.map), so errno is left unchanged
on success.

(cherry picked from commit 63262245d274342b693fda146ae9feca3752b6e3)
v_cvt_f32_ubyte0 accepts every SDWA source selector, but the other three byte
conversions had no VOP1 SDWA rule, so any SDWA source select on them was refused
("VOP1 SDWA source selector 4 of opcode 0x12 at pc 0xfcc is not supported").
The selected and optionally sign-extended source goes through the same operand
path as for ubyte0 before byte N is extracted: SDWA supplies source 0 (RDNA 2 ISA
guide 6.8 and 13.3.7) and the opcode reads S0.u[8N+7:8N] (12.8).
agc_driver_sdwa_cvt_f32_ubyte: WORD_0 and WORD_1 selects on ubyte1, and
sign-extended WORD_1 and BYTE_3 selects on ubyte2 and ubyte3.
The rebase onto main deleted docs/dev/TechnicalDebt.md, which is now the
index that points into docs/dev/debt/. Restore it from main and add the
missing final newline to docs/dev/debt/libSceNgs2.native.md.
Resolve a host name to its first IPv6 address through the host resolver
(getaddrinfo with AF_INET6) and write the 16-byte address. The lookup
shares the IPv4 path's resolver bookkeeping (abort preservation, error
state); a name without an IPv6 address fails with RESOLVER_ENODNS like a
failed lookup. Nonzero flags throw.
Metal Gear Solid 4 Master Collection (PPSA18194) imports it and failed to
load without it (unresolved zl35YNs9jnI from libSceNet.prx).

PS5MC (PPSA99420, Kodi 22) imports chflags (ixrw0h2tWuI) from
libkernel.prx, one reference. Predicted stop once the imports ahead of
it (pthread_getthreadid_np, sendfile, wcstok, pause, setrlimit and the
termios calls) are covered (not a run):
FAIL: unresolved ELF import ixrw0h2tWuI from libkernel.prx
The NID is computed with tools/nid_names.py and matches aerolib.
Follows FreeBSD 11.4 (8c639945a44588f6cfdddfb057bb5aad88735da0)
sys/kern/vfs_syscalls.c kern_chflagsat and setfflags, and
sys/ufs/ufs/ufs_vnops.c ufs_setattr, for a root caller: the lookup
through the guest resolver gives EFAULT, ENOENT and ENOTDIR (also for a
file reached through a trailing slash or used as a directory), a bit
outside the 17 UFS flags of sys/sys/stat.h (VNOVAL included) gives
EOPNOTSUPP, and SF_SNAPSHOT gives EPERM, since the snapshot flag cannot
be toggled. No host keeps BSD file flags and stat reports st_flags 0,
so flags 0 succeed without touching the file and any other flag throws
with the flags named. UF_READONLY and the other Windows-attribute flags
are not mapped to FILE_ATTRIBUTE_READONLY and its siblings: UFS stores
them without enforcing them, and on Windows the read-only attribute is
already the owner write bit of chmod.

(cherry picked from commit 16e5b7ccd04e6467a5a282b6cfc9271304f42244)
PS5CEMU-HAR (PPSA99360, ps5-payload-dev build, relinks with
--trap-sdk-syscall-stubs) imports pthread_setaffinity_np (5KWrg7-ZqvE)
from libkernel.prx. babyhuey's run with #3787 merged onto main e7c70a2d
(PR #3787, 2026-10-12T10:54:44Z) stops at it:
Windows: FAIL: unresolved ELF import 5KWrg7-ZqvE (pthread_setaffinity_np) from libkernel.prx
Linux: undefined symbol: 5KWrg7-ZqvE (pthread_setaffinity_np)
It follows FreeBSD 11.4 libthr thr_affinity.c (8c639945) over
kern_cpuset_setaffinity: another thread is looked up first (EINVAL for
null, ESRCH when unknown or finished, as _thr_find_thread without dead
threads), a size other than the 32-byte cpuset_t returns ERANGE, the
mask is clipped to sceKernelGetAvailableCpumask and an empty result
returns EDEADLK, as cpuset_setaffinity does. The affinity is stored on
the guest thread through scePthreadSetaffinity, for the caller and for
any live guest thread.

Add missing libc.prx symbols required by Unity IL2CPP runtime:
- Implement _Dtest double classification in Math.cpp
- Implement _Inf double constant in Math.cpp
- Implement sceLibcBacktraceGetBufferSize and sceLibcBacktraceSelf in Backtrace.cpp
- Implement _Cnd_signal in Threads.cpp
- Implement _ZNSt8ios_base7_AddstdEPS_ in RuntimeSupport.cpp
- Implement __pointer_type_info and __function_type_info vtables in TypeInfo.cpp
- Remove duplicate stubs from libSceAmpr/Export.cpp
- Add unit tests in GuestMath.cpp and GuestLibcThreads.cpp
- Document unverified behaviors in docs/dev/debt/libc.md
With --trace-imports the entry stub resolves TraceImport_nid_no_patch
in libc.prx and passes each function import through it before writing
the slot: every PLT slot, and a GOT slot only when the original symbol
is a function, so data imports such as __stdoutp keep their address.
Without the option the output is unchanged.

sceCoredumpAttachUserFile (5nc2gdLNsok) and
sceCoredumpAttachMemoryRegionAsUserFile (MEJ7tc7ThwM) get the
signatures of Orbital's db_types.json (cc408367) and SharpProspero's
KernelSystem.cs (5dfdb4b0): (uint32_t userValue, const char* path) and
(uint32_t userValue, const void* mem, size_t size, const char* name).
The handler is never invoked here, so both return
SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER (0x81180003, shadPS4
coredump_error.h e0a46675) and attach nothing; a null path or name and
a null, empty or wrapping region throw because the order of the
console's checks is unknown.

PPSA99058 and PPSA99420 import sceKernelGetCpuTemperature and sceKernelGetSocSensorTemperature and stop at start-up on main. Read the host CPU/package, board and NVMe sensors (hwmon/thermal on Linux, the ACPI thermal zones and the storage temperature property on Windows) and report an unsupported sensor with EINVAL.
2 Ship 2 Harkinian (PPSA99621) imports fchmodat through std::filesystem::permissions and stops at start-up on main. Resolve AT_FDCWD and absolute paths as usual and join other relative paths to the directory descriptor like openat, accept 0 and AT_SYMLINK_NOFOLLOW, and mask the mode to 07777.
TraceImport_nid_no_patch wraps a function of a library named in
APS5_TRACE_CALLS in a thunk that records the import, the thread and
the caller in a ring and counts the call, then jumps to the function.
One target keeps one thunk, so function pointers compare equal. The
crash and abort reports print the last 64 calls and the 32 most called
imports. Nothing calls TraceImport_nid_no_patch yet.
