What

Implements sceNetShowNetstat (NID WxislcDAW5I) as the pool-less form of the existing sceNetShowNetstatWithMemory: it writes the socket count and the same per-socket lines to standard output and returns 0.

Source of the behaviour. No console measurement is involved.

• Signature int (void): Orbital's IDA type database, db_types.json L1419 ("int sceNetShowNetstat(void)", PS4). The debt entry links the same line at b321fcd, the commit that last changed the file; the content is identical. The PS Vita SDK headers declare the same int sceNetShowNetstat(void) (vita-headers net.h L194).
• Output: the socket listing merged in feat(net): implement memory-pool netstat diagnostic boykopovar/AnyPS5#4785 for sceNetShowNetstatWithMemory, without its pool part. Like that listing, it is a host-side snapshot of the guest sockets (id, family, type, non-blocking, bound, listening), not the console's text. shadPS4's sceNetShowNetstat is a logged (STUBBED) return ORBIS_OK (net.cpp L2570-L2573) and gives no output format either.

Changes:

• core/libs/prx/libSceNet/Export.cpp: the socket snapshot and the per-socket printing move out of sceNetShowNetstatWithMemory into two static helpers, unchanged; its output and its EBADF for an unknown pool stay as they are. sceNetShowNetstat takes the snapshot under the network mutex, prints sceNet netstat: sockets=N and the socket lines after releasing it, and returns 0. It moves below the socket registry it reads.
• core/libs/tests/GuestSceNet.cpp: the stdout capture takes any call. guest_sce_net compares the complete output of sceNetShowNetstat with no socket, with a non-blocking bound listener, and after the socket is closed.
• docs/dev/debt/libSceNet.md: the existing entry, which listed the signature as unknown, records the Orbital signature and that the output format and any dependency on sceNetInit are unverified.

What stays unverified: the console's output text and destination, and whether the call needs sceNetInit or fails in any case; no case of this call throws. The signature is the PS4 one.

Progress: libSceNet 50/52 → 51/52; system libraries 3249/3678 (88.34%) → 3250/3678 (88.36%) by tools/progress.py on the branch base caee23f.

• Linux (Ubuntu 22.04, GCC 12.3.0, Ninja, Release, BUILD_TESTING=ON, tests run under QEMU 8.2 user mode with -cpu EPYC-Rome because the build host lacks AVX2): guest_sce_net_tests 5/5 passes.
• Negative control: keep the tests and replace only core/libs/prx/libSceNet/Export.cpp with the base version: guest_sce_net_tests fails with sceNetShowNetstat not implemented. Restoring the PR source and rebuilding passes guest_sce_net_tests 5/5.
• Windows: fork Build workflow pending; result added here when it finishes.
• Conventions checker and git diff --check pass. The Linux job of the Build workflow now targets the project's self-hosted runner, so it was not run on the fork; no title was run.

Duplicate and overlap check

Checked the files of all 443 open PRs on 2026-10-14 and searched open, merged and closed PRs for sceNetShowNetstat. No open PR implements or names it.

Open PRs sharing a file (pairwise git merge-tree against each PR head):

• fix(libSceNet): stop Sackboy loading retries on peer sockets boykopovar/AnyPS5#5836, fix(libSceNet): report SO_SNDBUF and SO_RCVBUF from sceNetGetsockopt boykopovar/AnyPS5#5536, fix(libkernel): refuse a loopback TCP connect at once on Windows boykopovar/AnyPS5#5141 (libSceNet/Export.cpp, GuestSceNet.cpp) and fix(libScePad): return measured status for unknown Pad NID boykopovar/AnyPS5#5676 (docs/dev/debt/libSceNet.md, the entry two lines above): no conflict.
• fix(libkernel): poll libSceNet sockets with the host wait boykopovar/AnyPS5#4933 and fix(libkernel): answer fcntl status flags on libSceNet sockets boykopovar/AnyPS5#4924 (libSceNet/Export.cpp, GuestSceNet.cpp) already conflict with main; this branch adds no conflict file or block to theirs.

Earlier PRs on the same export: boykopovar#2831 (merged) declared it as a throwing stub. boykopovar#3963 and boykopovar#5004, which returned 0 and printed nothing, were closed: no title was shown calling it, and the 0 return had no source for what the export does. This PR does print, with the format of boykopovar#4785, but has no console source for the output and no title stop (Unblocks is none).

The branch is one commit on caee23f; none of the newer commits on main (84b01f9) touch these files, and it merges without conflicts.
