GuestModuleWriter::WriteLinux adds read permission to every PT_LOAD, including
the SCE dynlib data segment, which has no flags and is never mapped on the PS5.
When that segment starts inside the last page of the preceding RW segment, the
read-only mapping covers the tail of its bss and the module's initializer faults
on its first write there. The symbol and relocation tables it holds are already
copied into the appended segment, so it no longer needs to be mapped.

The host-region fallback added with the Demon's Souls work calls VirtualQuery and
includes windows.h unconditionally, so libkernel no longer compiles on Linux.
On Linux, read the containing mapping and its permissions from /proc/self/maps.

Every lock, unlock, signal and wait took the process-wide initialisation
mutex to read the handle, serialising all guest synchronisation. The
handle is now read atomically and the lock is only taken to initialise a
static initializer or to report a destroyed object.

The merge brought a NotImplemented scePthreadOnce_nid_postfix next to the
existing scePthreadOnce. The NID patcher gives the NID to the postfixed
symbol, so the stub replaced the working export and the title aborted at
its first once-initialisation.

When the presentation device was replaced, textures created on the old
device stayed in the global sampled and storage texture caches and kept a
reference to the destroyed TextureDetiler, whose VkDevice was then read
corrupted ("missing Vulkan function: vkResetDescriptorPool" at startup).
The replacement now flushes the old device's cached storage textures and
publishes every unit shadow before waiting for the device, and the device
teardown erases the cache entries that belong to it.

Brings in main up to 9958d26 (homebrew runtime, POSIX wrappers in
libkernel, sce_module guest modules and --skip-sce-module, the --to-intel
general pipeline, libSceRandom, libSceRtc, libScePosixForWebKit,
libRenoirCore, test wiring).
Resolutions where both sides implemented the same thing:
- libkernel pthread: main's structure (lazy static initialisation,
destroyed markers, MutexOperations/CondOperations, mutex protocol and
condattr clock) with this branch's TimedWait deadlines and condition
(precise timed lock/wait on Windows), wait tracing, the adaptive mutex
type 4, POSIX default ERRORCHECK mutexes, EDEADLK/EPERM results instead
of throws, and condition clocks honoured for absolute timeouts.
- libc locale: the guest Dinkumware ABI (_Locimp, facet vtables, short
ctype/case tables, locale ids, stream storage) is kept because guest code
inlines those layouts; main's C character functions are kept on top.
- libc stdio/strings/math: main's stream functions (guest FILE status
sync), strerror/perror, remove, formatting, string and math exports win
over this branch's duplicates.
- libc paths: main's working directory with this branch's path aliases
resolved on the normalised guest path.
- libkernel file: this branch's sceKernel* results as SCE errors, main's
POSIX wrappers and both fstat helpers.
- relinker: this branch's stub lowering keeps its trampolines through the
main executable path; guest modules refuse lowerings that need stubs.
- AGC driver: main's rendering wait is executed by this branch's workers.

sceAgcDcbDrawIndexIndirect and sceAgcDcbDrawIndexIndirectMulti emit
DRAW_INDEX_INDIRECT (0x25) and DRAW_INDEX_INDIRECT_MULTI (0x38) like their
non-indexed counterparts, with 20-byte records.

readU32Pair read a literal or inline constant into both halves of a 64-bit
source. A literal is now zero-extended, an integer inline constant
sign-extended and a float inline constant becomes the matching double.

Convert 5 remaining pure stubs (log + return 0) to throwing with
literal NID, keep trailing return 0. Real SDL/state-tracking impls
(20 studio + 2 libfmod + C++ classes) untouched. Remove stale
logging-stub comments only around touched stubs.
Throwing: Cm2cmtCv8cA, EfM9xXvBmxk, Js90KQXVS4s, oCYWES02VPc, vVwA2cZA5e4
Copy the patched libcohtml.prx to libcohtml.Prospero.prx (exact DT_NEEDED name) via a post-build copy in the module CMakeLists, wired into the libs umbrella target. OUTPUT_NAME with a dot was rejected: the parent pipeline derives unpatched/patched paths from the directory target name, so renaming output would break it; dotted CMake target names are supported (e.g. libSceSaveData.native) but the parent-owned NID-patch rule is kept untouched. Adds DEPLOY.md deploy note. All 50 raw NIDs re-verified in the renamed file export table.
Minecraft Legends' libcohtml.Prospero.prx imports 23 NIDs from lib
libRenoirCore.PS5_v1 (docs/legends-unresolved-nids.json). Clear names are
unknown, so each export is exposed under its raw NID via APS5_EXPORT
alias (<NID>_nid_no_patch_cut), which nid_patcher strips to the
literal NID instead of hashing.
Stubs follow KytyPS5 UnresolvedImportStub policy (log call + return 0)
via APS5_LOG_OUT rather than throwing NotImplemented.
