Add the long-double siblings of _Cosh and _Sinh with the same scaled finite-input path, signed-zero handling and Dinkumware two-argument contracts. The reductions use a long-double ln2 split, and the scaled-range tests pin 64-bit results instead of the intermediate writer's output. Cover known values, signs and non-finite inputs in guest_math; record the unverified console results and exception behavior in the libc debt list.
Resolved GuestPsml.cpp by dropping the extern block; the Mfsr2 placeholders in the libScePsml_debug header now carry the implemented signatures and the test uses the library header.

DecodeColorBuffer dropped the DCC address of a color target with more than
one mip, so the target's resident image had no keys: it was uploaded from
guest memory under the game's fast-clear keys, and no draw into it marked
them uncompressed. The game's textures over the same chain name the keys,
so they kept sampling the clear (0000 reads as (0,0,0,0)) whatever was
drawn. MXGP 26, Borderlands 4 and Forspoken render such targets.
- ColorTarget.chainDccAddress keeps the keys of a 2D single-layer chain;
dccAddress stays 0, so the per-draw single-mip key handling is unchanged.
- SurfaceForTarget gives the resident surface those keys, and the image
then treats them as a multi-mip storage image does: a uniform clear is
cleared on the GPU at upload, and the first write marks every key
uncompressed.
- A draw recipe's key check uses the surface's keys.
- sizeof(State) is 840: the recipe codec and CanonicalPipelineState do not
copy the field.

Resolved Export.cpp and GuestVrTracker2.cpp keeping main's header layout; the new sceHmd2Internal exports are declared in the libSceHmd2 header and the test uses the library headers.

Resolve a FreeBSD/ELF tls_index {module, offset} the way the relinker's
DTPMOD64 values are laid out: on Windows through the PE _tls_index the
module word points at and the thread's ThreadLocalStoragePointer, on
Linux through glibc's __tls_get_addr.
A string created from a text source in the default horizontal form (0x10)
reported 0x10. TEKKEN: DARK RESURRECTION (PPSA31371) passes the reported form
to sceFontCreateWritingLine, which only accepts 0x11 and 0x12, so the call
failed and the layout width was 0.
On firmware 13.42 sceFontCreateString decides the direction for a default-form
source and sceFontStringGetWritingForm returns the stored form. The string
gets 0x12 when its first strong character is left to right, 0x11 when it is
right to left, and 0x12 when it has none. Left-to-right and right-to-left marks
count as strong, embeddings and overrides do not, and text between an isolate
initiator and its PDI is skipped. Explicit 0x11 and 0x12 sources keep their
form.
The test follows the table reported on the pull request. Which characters are
strong is decided by Unicode block ranges here, not by the full bidi class
tables.
A traced run that ends without a crash or an abort never reports which
imports it called. With APS5_TRACE_CALLS_FILE set, the first traced import
starts a thread that rewrites that file every 10 seconds with every import
called so far, most called first.

scePthreadMutexTimedlock on a mutex the caller holds, and
scePthreadRwlockTimedrdlock and scePthreadRwlockTimedwrlock on a rwlock
it holds for writing, returned EDEADLK at once. The console returns
ETIMEDOUT, as the prosper console oracle measured. They now sleep until
the timeout and return ETIMEDOUT, as FreeBSD libthr does. The POSIX
timed locks call these and change with them.

The graphics pipeline store kept a fixed 1024 entries and the pipeline journal replayed at most
1024 records, and a replayed pipeline that found the store full was dropped. A title whose
working set is larger rebuilt the rest at the draw on every run, and evicted pipelines it kept
using were rebuilt again and again.
The bound now starts at 1024 and doubles up to 4096: a journal replay that does not fit grows it
instead of dropping the pipeline, and so does eviction churn (a ghost list of evicted keys, checked
every bound/32 evictions: more than half of them came back). It never shrinks during a run;
APS5_PIPELINE_STORE_ENTRIES still fixes it. The journal loads its last 4096 records by default
(APS5_PIPELINE_JOURNAL_ENTRIES). Resident pipelines are bounded by count, not bytes.
agc_driver_recorder_tests --benchmark-pipeline-store-memory [count] (opt-in, not registered)
builds count graphics pipelines with one fragment module each through CachedPipeline and prints
process private bytes and VK_EXT_memory_budget heap usage before and after: with the triangle
shaders about 59 KiB host and no device memory per pipeline on an RTX 4090, 100 KiB host and
8 KiB device-local on a UHD 770.
Tests: agc_pipeline_store_growth (fails on main), agc_pipeline_store_fixed_bound,
agc_pipeline_store_replay_growth (replays on one thread: the mock Vulkan is not thread-safe).

sceUsbdGetDevice, sceUsbdGetDeviceSpeed, sceUsbdGetMaxPacketSize,
sceUsbdGetMaxIsoPacketSize, sceUsbdOpenDeviceWithVidPid,
sceUsbdSetInterfaceAltSetting, sceUsbdClearHalt and
sceUsbdDetachKernelDriver follow FreeBSD 11.4 libusb10.c over the host
libusb. The packet sizes and the alternate setting checks are done as
FreeBSD does them, so the library records which interfaces are claimed,
and a device stays known while a handle to it is open.
