D778 - libSceSysmodule's unwind query is the kernel's

Status: decided Date: 2026-10-09 known_by: assumed (the names match; nothing on the target compares the two)

sceSysmoduleGetModuleInfoForUnwind(address, flags, info) answers exactly as libkernel's sceKernelGetModuleInfoForUnwind does (D768). It fills the same block of the module holding address, and refuses as it refuses. The implementation is the kernel's function, registered under the second name.

Why: PPSA02664's libc asks the sysmodule spelling 1100 times a run, and every call landed on a stub. The two names differ only in library, and the census found both on the system. A copy of the kernel's semantics would be a second place to keep them true.
