strtof and wcstof now set ERANGE for a decimal input whose nonzero
subnormal result is inexact, never for a hexadecimal nonzero subnormal,
and keep it for underflow to zero and overflow. This is what the libc.prx
bundled with PPSA08427 (J03547016) and PPSA03671 (J03848509) do when run
side by side with this libc. The earlier commit followed
libSceLibcInternal's _Stof, which leaves errno alone for hexadecimal under-
and overflow, but titles import these NIDs from their own libc.prx.

PS5VR (PPSA99177) reads sysctl {CTL_KERN, KERN_PROC, KERN_PROC_ENV, pid}
for its own pid at start-up and stopped on "unsupported MIB 1.14.35.<pid>".
The call now returns the empty start-up environment that environ and
libc's getenv also begin with, and follows FreeBSD 11's
sysctl_kern_proc_env for the errors: EINVAL for a MIB without exactly one
pid, ESRCH for another pid or -1, EPERM for a write.

Mode 1 threw for every input since fe4016f61, which stopped Grand Theft Auto V (PPSA04264) right after sceVoiceInit. It now returns 0 for priorities 256-767 with non-zero affinity masks within 0x1fff, the range sceVideoOutOpen accepts for its service thread; no voice worker threads run, so the values reach no host scheduling, and other values still throw.
The trap checks unmask exceptions with feenableexcept and its relatives
and expect MXCSR to hold the new masks, and the enable and disable
results to report the traps enabled on both units. Under Rosetta 2
MXCSR keeps its six exception masks set, so no SSE trap is ever enabled
and every result reports none. The test now asks the host once whether
it keeps an unmasked MXCSR exception and, where it does not, expects
all six SSE masks set and no trap on both units; on other hosts the
expectations are the same as before. A debt entry records that the
trap functions change only the x87 masks under Rosetta.
Under Rosetta 2 the six MXCSR exception masks always read back set: a
write that unmasks an SSE exception is not kept, while the x87 masks and
the other MXCSR bits are. guest_floating_point unmasked the overflow
exception on both units and then expected MXCSR to equal the value it
wrote, so it failed on macOS although fesetexceptflag and feclearexcept
left the masks alone. The test now compares with the environment read
back after the write, which on other hosts is the value written. The
debt entry for the floating-point functions notes the Rosetta behaviour.
main now starts libSceNetCtl initialized, so GuestNetCtl's checks before
sceNetCtlInit expect argument errors; the NpToolkit register, unregister
and check join them with the errors and result their IPv4 counterparts give.
BunnyFl ran firmware 13.42's libSceHmd exports under an emulator. The
distortion and wide-near correction queries look the handle up before
checking initialization: a handle other than the one sceHmdOpen stored,
which stays 0 without a headset, returns HANDLE_INVALID even before
sceHmdInitialize. sceHmdGet2dVrCommand checks its arguments first:
PARAMETER_NULL for a null descriptor or command buffer or a null
pointer at descriptor offset 0, 8 or 0x20, and PARAMETER_INVALID for a
non-zero field at 0x34 or 0x38.
The queries and their sceHmdDistortion* aliases now answer in that
order. What handle 0 gets after initialization isn't measured, so it
throws NotImplemented_nid_no_patch instead of returning HANDLE_INVALID.
Each GCN instruction is re-encoded to its RDNA form and decoded by the
existing RDNA decoder, so the PS4 path shares the recompiler. Covers the
legacy VS stage (program at the VS slot, user SGPRs from s0, vertex and
instance index in v0-v3), fetch shaders linked as user-data calls, MIMG
(image_sample and friends), PS4 buffer descriptors (GCN DATA_FORMAT /
NUM_FORMAT, 44-bit base) and T# image descriptors (GCN tiling in word 7).
The GCN switch is keyed into the shader disk cache. PS5 behaviour is
unchanged: every PS4-only rule is gated on GcnGuestShaders().
A one-sample depth target under a multisampled rasterizer without MSAA_ENABLE is drawn as one sample at the pixel center, but DB_EQAA INTERPOLATE_COMP_Z threw on it. Gran Turismo 7 (PPSA01317) draws its 3840x2160 main pass this way after its EQAA pass (PA_SC_AA_CONFIG 0x0020c002, PA_SC_MODE_CNTL_0 0x2, DB_EQAA 0x00050000, a Z_32_FLOAT depth target with one sample) and stops on it.
On this path every sample is taken to be at the pixel center, so Z interpolated to any sample position is the center's Z, which the one-sample draw already tests and writes. INTERPOLATE_COMP_Z is now accepted there. INTERPOLATE_SRC_Z and overrasterization still throw. Neither PAL nor radeonsi sets the bit and its meaning is not documented, so the debt entry records this as the same inference.
A second sceCommonDialogInitialize returned 0x80B80004
(ALREADY_INITIALIZED), the code each dialog's own Initialize returns.
The common-dialog system initializer returns 0x80B80002
(ALREADY_SYSTEM_INITIALIZED), as shadPS4 and the SDK error names have
it, so callers that accept only SCE_OK or ALREADY_SYSTEM_INITIALIZED
treated a second call as a failure. The header keeps
ALREADY_INITIALIZED for the dialog libraries that return it. The test
pins the literal instead of the header constant, and the debt entry
records that a repeated call's value is not measured on a console.

A guest read over the depth or HTILE range of a native multisample depth
surface threw even when the host had not written the surface since its
import. Its samples are then still the clear value the import took from
the guest HTILE, so the guest bytes already describe it. Retire such a
surface and its guards instead, and keep the refusal for a surface the
host wrote: draws with depth or stencil writes, depth/stencil copies and
storage write-back.
Onimusha: Way of the Sword (PPSA27836) imports a 4-sample D32 target,
draws into it once with depth tests only and no color target, then reads
the memory back as a structured buffer in a compute dispatch.
Unblocks PPSA27836.

Implement sceVoiceSetMuteFlagAll, sceVoiceSetBitRate and
sceVoiceUpdatePort on main's port model. They return the
not-initialized, port-range and missing-port codes of the other port
calls, validate bitrates against the table sceVoiceCreatePort uses and
throw where the console's code is unknown.

Take main's restored signatures (the firmware-database sweep of 2026-10-21):
the typed UsbStorageCallback across the register/unregister family, the
UsbStorageDeviceInfo-typed device-info query, IsExist's three-argument bool
form (succeeds and reports non-existence with no device attached), and
RequestMap's six parameters with the trailing reserved pair dropped. The
no-device answers and the argument validation are unchanged; the guest test
passes an APS5_VABI callback and pins the exists out-parameter.
The first entry in the libSceNpSns debt file lists 24 names, but Export.cpp declares 21. The note two entries below says that sceNpSnsFacebookCreateRequest, sceNpSnsFacebookDeleteRequest and sceNpSnsFacebookGetAccessToken are omitted from this module because another module declares them. They are declared in libSceNpManager (Export.cpp, since f04d16d702), not in libSceNpSnsFacebookDialog by #6977 as the note still says. The three names are removed from the entry so that it names exactly the 21 declared functions, and the note now names libSceNpManager. No code changes.
