FreeBSD msun e_acosf.c returns (x-x)/(x-x) for |x| > 1 and NaN inputs: the
x86 default NaN 0xffc00000, or the quieted input NaN. std::acos left it to the
host libm, and guest_math failed on the runner's glibc 2.39.

PPSA99611 imports ceilf, floorf, truncf, isnan and isinf from libc.prx and stops at start-up on main. Implement them next to the existing double forms: the rounding results delegate to the standard library like the other float exports, and isnan/isinf reuse the __isnan/__isinf helpers isnanf already uses.
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.

A formatted store of an 8- or 16-bit component into a bound buffer
patched the dword around it with a compare-exchange loop (writeBuffer
in SpirvRuntimeBuffer.cpp). Ghost of Yotei's light-culling compute
pass (program 0x800038be00, 240x135 groups per frame) stores millions
of such components per dispatch and took 426 ms of GPU time per
dispatch on an RTX 4070 Ti SUPER.
Compute stores now go through a byte view of the bound buffers
(buffers_u8, an aliased declaration of the buffers binding, defined
on the first narrow store): one OpStore per byte under
StorageBuffer8BitAccess, which the shader device profile already
requires. Without the capability, and in every other stage, the
compare-exchange path remains: the draw-time validator accepts only
u32 and u64 aliased views. Loads, dword stores and stores through
GPU-selected descriptors (BDA) are unchanged.
Ghost of Yotei (PPSA26344 02.002.000), Windows 11, RTX 4070 Ti SUPER,
logo phase: that dispatch 426 -> 10.7 ms of GPU time, 1.9 -> 11 fps.
agc_formatted_buffer_byte_stores compiles a formatted 8_8_8_8 store
as compute with and without StorageBuffer8BitAccess and as a vertex
shader with it, and checks the byte view, the byte stores, the
compare-exchange loops and the fallbacks. agc_driver_formatted_store_unaligned
executes 8- and 16-bit formatted stores at misaligned offsets,
including stores that cross a dword, and checks every byte of the
output including the untouched neighbours.

The signature (uint32_t service label, const NpUnifiedEntitlementLabel*)
follows SharpProspero Interop/AppContent/AppContent.cs (5dfdb4b0). dlc_emu
dlc_content.cpp (fcf69b16) answers NOT_FOUND for a label that is not a
known add-on and PARAMETER for a null label. No add-on content is ever
installed here, as sceAppContentAddcontMount and sceAppContentGetAddcontInfo
already model, so every non-null label answers NOT_FOUND and nothing is
queued. dlc_emu's nonzero-padding check is left out, as sibling functions
do not check it and no console source confirms it.

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.
textureClearKeys reads the keys through a raw pointer, past the flush hook, so writes the
recorder holds for the key range are not in the bytes yet. A title that clears the keys of a
target with a kernel and samples it in the same batch had its keys read from the memory's
previous contents: in Palworld (PPSA23126) these were the float data of a reused heap, so the
keys read as mixed and the texels were read as stored.
When the keys read do not decode (not uncompressed, not a clear the format can fill),
WaitForKeyWriters answers from the pending fills and stores it knows, or waits for the batch
that writes the keys, and the keys are read again. Keys that decode are used as before.
RunSampledKeysBehindKernel (agc_driver_dcc_keys_first_write): key memory holding float bytes,
then the 0000 clear kernel recorded without a wait; the sampled texture's keys read Clear0000.
