Black Myth: Wukong (PPSA23226) exits at start-up with STATUS_DLL_NOT_FOUND after "Failed to load module: libs\libSceDbgThreadSanitizer.prx". The executable does not need the library: its bundled sce_module/libSceJobManager_nosubmission.prx lists it in DT_NEEDED and imports __tsan_acquire and __tsan_release from it, plus sceKernelIsThreadSanitizerEnabled from libkernel. The relinker converts every module in sce_module and loads it at start-up (only --module-dir directories are deferred), and GuestModuleBuilder adds each module's host dependencies to the executable's DT_NEEDED, which the Windows start-up stub loads. libSceDbgThreadSanitizer now exports __tsan_acquire and __tsan_release with the void(void* addr) signatures of LLVM compiler-rt's tsan_interface.h (llvm-project 87f0227cb601, LLVM 20.1.8). Both throw: AnyPS5 runs no race detector, and the module calls them only after sceKernelIsThreadSanitizerEnabled reports the sanitizer enabled. libkernel's sceKernelIsThreadSanitizerEnabled returns 0, as sceKernelIsAddressSanitizerEnabled does; its int(void) signature is assumed and recorded in the libkernel debt file.

- [__tsan_acquire, __tsan_release](../../../core/libs/prx/libSceDbgThreadSanitizer/Export.cpp) (libSceDbgThreadSanitizer, NIDs `XyX1104ACcU` and `IkoI44e0OXc`) - declared as throwing stubs: AnyPS5 runs no race detector. The `void (void* addr)` signatures are those of LLVM compiler-rt's [tsan_interface.h](https://github.com/llvm/llvm-project/blob/87f0227cb60147a26a1eeb4fb06e3b505e9c7261/compiler-rt/include/sanitizer/tsan_interface.h#L24-L25), whose names hash to the imported NIDs; that the console library has the same signatures is assumed. PPSA23226's bundled `libSceJobManager_nosubmission.prx` imports both and calls them only after [sceKernelIsThreadSanitizerEnabled](../../../core/libs/prx/libkernel/System/src/Sanitizer.cpp) reports the sanitizer enabled, which it never does here
