Titles resolve NID 59oywaaZbJk as a 112-byte STT_OBJECT on PPSA16833 libc.prx; export fourteen zeroed slots and the matching id so the data object exists while facet methods stay unwired.
expm1 returned the host's expm1, whose last bit differs from the titles'
copy on Windows on 35,152,346 of 320 million random arguments. The titles'
copy is FreeBSD msun's s_expm1.c, and it sets ERANGE only when a finite
argument overflows to infinity. expm1 now computes that algorithm and sets
ERANGE there.

A Windows process started without a standard handle, such as a detached
process or a --windows-gui executable started from Explorer, has
descriptors 0 to 2 whose _get_osfhandle is -2. fcntl then threw on their
unknown file type, which stopped Halo: Combat Evolved (PPSA99500) at
start-up. Open NUL on each of them when libc loads, as Linux and macOS
already open /dev/null on a closed standard descriptor.

strcasecmp and strncasecmp returned the folded unsigned-byte difference,
following FreeBSD 11.4's strcasecmp.c (#3966, #9642). The libc.prx bundled
with eleven titles returns -1, 0 or 1, the sign of that difference; both
functions now do the same, and the byte-pair tests expect it.

The libc.prx that PS4 titles ship (measured for CUSA04865 and CUSA12435 on a
PS4 Pro, firmware 10.71) names 0 "No error", 1 to 94 with the FreeBSD texts
(30 is "Read-only filesystem"), answers every other number, 95 and 96
included, with "error_code=0x%08x", and leaves errno alone. AnyPS5 returned
"No error: 0", named 95 and 96, answered "Unknown error: %d" and set errno
to 22. strerror_r and perror keep their wording; only the shared EROFS text
changes for them.

Console title libc.prx (PPSA26344) and libSceLibcInternal export H-TDszhsYuY as STT_OBJECT st_size 104; titles that resolve it as data need thirteen zeroed uintptr_t slots.
The debt entry says the rule follows a static reading of the console's
wcsncat_s in libc.prx, that wcscat_s inherits it unread, and that the
narrow strncat_s keeps a wider rule, as asked in review.

FreeBSD 11.4's lookup() (sys/kern/vfs_lookup.c) fails with ENOTDIR when
a path with a trailing slash ends at something that is not a directory.
On Windows a mount alias dropped the slash, and the host calls do not
report ENOTDIR for "file\", so unlink, rename and open acted on the file
or failed with EINVAL. Guest path resolution now rejects an existing
non-directory named with a trailing slash with ENOTDIR on every host, and
a mount alias keeps the slash on Windows as it does on Linux and macOS.
