On a PS5 (firmware 12.70), of the values 0, 1, 2 and -1,
pthread_spin_init, pthread_barrierattr_setpshared and
pthread_mutexattr_setpshared accept only PTHREAD_PROCESS_PRIVATE (0);
1, 2 and -1 return EINVAL and leave the attribute unchanged.

Prospero Themes (PPSA90210) imports nmount (3YnXspQNyw8) from libkernel
and fails to load without it:
"./app.elf: symbol lookup error: ./app.elf: undefined symbol: 3YnXspQNyw8".
Mounting file systems is not supported, so it throws if called, like
execvp does for executable replacement. The title opens its theme
library without calling it.

PSFlyCast (PPSA99247) imports pthread_condattr_setpshared (3BpP850hBT4)
from libkernel and fails to load without it:
"./app.elf: symbol lookup error: ./app.elf: undefined symbol: 3BpP850hBT4".
The attribute stores PTHREAD_PROCESS_PRIVATE (0) or
PTHREAD_PROCESS_SHARED (1); a null or uninitialized attribute and any
other value return EINVAL without changing it, following FreeBSD 11
libthr thr_condattr.c and pthread_mutexattr_setpshared here. Sharing
across processes is not modeled, as for mutexes.

Goosebumps Terror in Little Creek (PPSA27305) aborts in gameplay with
"unsupported color format 16 number type 0 component swap 2": it renders
into a COLOR_5_6_5 UNORM target. The target now renders into
R5G6B5_UNORM_PACK16. AMD keeps X in bits 0-4 and Z in bits 11-15, and
Mesa's ac_translate_colorswap programs SWAP_STD_REV for a surface with
red in bits 11-15, so with SWAP_STD_REV the exports are written as they
are and with SWAP_STD they are written with X and Z exchanged, as for
1_5_5_5. The alternate swaps and other number types keep throwing.

Prevent reached null conversion destinations from crashing sscanf_s and vsscanf_s. Return EOF before writes and retain earlier assignments. Add regression coverage through both guest ABI entry points.
AI-assisted: yes (OpenAI Codex). Windows WinLibs GCC 15.2 Release: production baseline crashes with the new regression; fixed shared libc passes guest_scan_count, guest_formatting, guest_wide_formatting and guest_strings (4/4). Conventions pass. Full all-target build was deliberately stopped after 83s with 3691 pending targets, not completed. No title or console run; constraint-handler invocation remains unimplemented as documented. No performance or coverage-percentage claim.
The entry sat right after "connect to AF_UNSPEC", where the open #6884 adds
its own entry, so whichever merges second would conflict. Move it after the
mlockall entry, which no open pull request changes. The text is unchanged.

socket() returned EPROTONOSUPPORT for every socket type it does not create.
FreeBSD 11.4's socreate returns EPROTOTYPE when no protocol is found, the
protocol is 0 and the type is not 0, and EPROTONOSUPPORT when a protocol was
given. Its inet domain (in_proto.c) has SOCK_RAW entries in every kernel and
a SOCK_SEQPACKET entry only with SCTP, and no SOCK_RDM or other type.
Return EPROTOTYPE for a type the inet domain never has, such as SOCK_RDM,
with protocol 0. SOCK_RAW and SOCK_SEQPACKET keep EPROTONOSUPPORT, since
whether the console creates them is not known. Test the unknown types and
mismatched protocols for AF_INET and AF_INET6, and list the socket types and
families that are not created in the library's technical debt file.

The Rosetta conversion limits were measured on an M1 running macOS 15.3.1
and an M5 Max. A survey on an M5 running macOS 26.4 executes ANDN, RDRAND,
the rest of BMI1 and BMI2, LZCNT, PREFETCHW, CLFLUSHOPT, AVX, AVX2, FMA,
F16C and MOVBE while CPUID reports none of them, and raises an illegal
instruction for RDSEED, CLWB, RDPID, ADCX and ADOX.
`Path.write_text(newline=...)` and `zip(strict=True)` were added in
Python 3.10. macOS ships 3.9.6 as /usr/bin/python3, the interpreter CMake
finds when no newer one is installed, so `prepare_release_notes` raised
TypeError when the release workflow wrote its notes and the
`pr_overlap_tools`, `release_package` and `linux_fixed_base` tests failed
on a stock macOS host. Writing the encoded text keeps the newline
translation off on every host, and the dynamic tag counts are compared
before the pairs are walked.
