The SDK libc.a's syscalls.o stubs (mov $N,%rax; syscall; ret) never check the carry flag, so a failing call returns the errno value as a result: openat "returned" fd 2 for ENOENT, unlinkat "succeeded". std linked dup, openat and unlinkat from there. - ps5-std-rt/build.rs: disassembles the installed SDK's syscalls.o and generates all 232 stubs (fstatat excluded, it's ours) with the same numbers plus `jb __ps5_cerror` (errno + -1); any stub with another shape stops the build. Drops syscalls.o from the patched libc copy, which no longer needs the fstatat rename. - std-examples/err_probe: provokes failures (bad fds, missing paths, refused connect, port in use) via libc and std, port 9960. Tested on CFI-1215A, fw 13.60: all errors reported as -1 + errno; the SDK-style stub returns 2. faccessat/readlinkat give ENOSYS from the PS5 kernel itself. fs_probe and https_probe unchanged.
