The H+8UBOwfScI import was a throwing stub (libcCyberUnknown08). It is
the NID of "__powidf2", the double-precision integer-power helper that
complements __powisf2.
`LibcHeapErrorReportForGame_nid_postfix` exports NID SlMztUijOSk, which no
NID list or emulator knows. The name is KytyPS5's label for al3JzFI9MQ0,
the NID of sceLibcInternalHeapErrorReportForGame, which libc already
exports from HeapDiagnostics.cpp.

The plain-named twin of std::_Execute_once delegates to that symbol and inherits its call_once semantics; the name-equivalence assumption is recorded in TechnicalDebt. Registers guest_std_execute_once_tests.
The DQbtGaBKlaw import was a throwing stub (libcCyberUnknown17). It is
the NID of "strnlen_s", which C11 K.3.7.4.4 defines as strnlen that
returns 0 for a null pointer.
The removed stub comment from #358 described its call site as
float -> float, which contradicts the hash-verified name; #492 left the
stub untouched for that reason.
Comments in this codebase may only mark technical debt (per
docs/dev/CONVENTIONS.md), plus the #endif and namespace-close
structural exceptions. Removes the descriptive comments added on
this branch across PreciseWait.hpp, FormattingWide.cpp, the
direct-memory pool query/free-run plumbing, and the module loader
wiring, keeping the two allowed structural markers intact.
- Add FormattingWide.cpp implementing vswprintf_nid_postfix and
wprintf_nid_postfix, the only wide-char printf-family functions
upstream had left as unimplemented stubs (Formatting.cpp's checked
and unchecked narrow printf/scanf families are unaffected). Removes
the dead vswprintf_nid_postfix stub from Export.cpp.
- Add PreciseWait.hpp: std::condition_variable::wait_for cannot return
in under about one system tick on this MinGW toolchain regardless of
the requested budget, even with NtSetTimerResolution; PreciseSleepUs
uses a high-resolution waitable timer instead (~0.5ms vs ~15.6ms).
Header-only for now: its guest-side callers (Equeue/EventFlag/
Semaphore/AgcDriver wait loops) are out of scope for this change, so
it is not wired into them here.
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.

- libc: reserve guest memory in one arena below the PS5 map limit with
MEM_WRITE_WATCH (GuestArena) and a caching guest heap; the allocation
registry gains a generation counter, an invalidator callback for the
driver's page cache and a pin waiter for leased ranges. This replaces
the fault-based GuestMemoryTracking/GuestMemoryBacking layer, whose
files are removed.
- libkernel: mmap/mprotect/munmap on the arena, flexible memory budget,
real sceKernelVirtualQuery; POSIX pthread layer, rwlocks, timed locks,
TSD, event flags; 0.5 ms scheduler tick and high-resolution sleeps;
TSC/clock/time functions; file APIs return SCE errno codes; the APR
file-streaming API.
- libc: vectored crash reporter with backtraces for fatal exceptions,
SIGABRT, UCRT invalid parameters and process exit; SSE4a EXTRQ/INSERTQ
emulation for Intel hosts; %ls/%lc/%S/%C with the guest's 16-bit
wchar_t; hand-written setjmp/longjmp for the guest jmp_buf; a path
alias table for short save-data mount points; more string, stdio and
math exports.
