Move the guest_move registration in core/libs/CMakeLists.txt next to the
voice tests so it no longer shares lines with the netctl access point
tests that another open pull request adds.

The seven fixed-unit additions (Ticks, Microseconds, Seconds, Minutes,
Hours, Days, Weeks) now only check the two pointers and store the source
plus the amount modulo 2^64; they no longer return 0x80B50003 for a source
above 9999-12-31 or a result outside the tick range.
sceRtcTickAddMonths and sceRtcTickAddYears no longer reject a source tick
above the 9999 limit. They split the tick into a 16-bit year, add the months
in 32 bits and divide by 12 truncating toward zero. They return 0 without
writing when the 16-bit target year is outside 1 to 9999 or the month sum is
negative and not a multiple of 12; otherwise they write the result.
Observed by executing the code of libSceRtc.sprx from PS5 firmware 3.20 and
4.03 in an emulator with its imports mocked (entry points 0x32c0-0x3440,
0x3470, 0x37f0 on 3.20; 0x3370-0x34f0, 0x3520, 0x3890 on 4.03), not on a
console. Both firmwares give identical results on the same inputs. Current
firmware was not checked.

sceVideodec2Decode threw for these, which ended the title. Media Player Classic PS5 submits an empty unit when its own converter misreads a length prefix as a start code, and it counts the error and keeps playing on a console.
sceMoveOpen returned a new handle for any user, type and index, although
the console's result for a user other than the initial user and for a
type and index that are already open is not known. Both now throw, as
libSceHmd2 does for another user. Record which shadPS4 behaviour the
handle and open checks add to.

The word reaches the data-only mask through userDataRegisterReads (the stage
layout's user-data registers). Dropping those bits from the mask makes the
draw reuse the old stage (it writes 127, expected 191) and verify mode abort.
LLM assistance used.

A data-only hit (#494) reused a cached stage only when every user data word
of the stage was unchanged. A stage records the user words it depends on when
it is captured: the words its SRT walk reads as values or bases
(SrtUserDataUse), the words its binding layout forwards into shader data
(userDataRegisterReads), and the vertex fetch table words of its vertex stage
info. A cached stage is now a candidate when only words outside that set
changed; its captured memory is validated as before.

MCOMMIT becomes STC plus NOP padding and RDPRU goes through a
runtime-checked stub returning the host TSC for MPERF/APERF while
other selectors yield zero, with converter and execution tests.
docs/dev/debt/relinker.md records the new lowering and its unverified
assumptions.
APS5_COARSE_TIMED_WAITS is read under _WIN32 only; on Linux the condition
variable path always ends a sleep when a completion arrives.

PS4 titles import both and do not load without them; every call throws and
the debt files list them.

agc_driver_resource_cache_replaced_texture clears the sampled cache
under a template that takes the fast proof and requires the next proof
to fail. agc_driver_resource_cache_lookup_changed checks that a proof
past the audit interval takes the full walk and keeps an unchanged
template, then host-imports the surface (no lookup runs) and requires
the template to stop proving current. Both run over a write-watched
surface so the template takes the fast proof.
The fast proof of a cached ShaderResources proves each sampled texture
from write stamps, keys and the pending registry. It never asks whether
the sampled lookup would still return the bound Texture, so a template
whose surface memory is unchanged keeps binding an old object:
- After the sampled cache drops or replaces the entry (#6492 marks the
texture released), Find keeps serving the template until the next
Insert, and its fast proof passes.
- When the lookup's answer changes without any lookup running (a
snapshot whose surface became host-imported is viewed through its
storage image from then on), nothing replaces the entry and the
template keeps the snapshot until it leaves the resource cache.
The fast proof now fails with 'replaced texture' when a bound texture
is released. A template whose last full walk is older than
APS5_TEMPLATE_AUDIT_MS (default 1000, 0 turns it off) takes the full
walk instead of the fast proof ('audit'), so a different lookup answer
fails the proof and the template is rebuilt.
Prevent decimal-comma LC_NUMERIC from emitting invalid JSON and silently truncating decimal-point input. Keep 17-digit output, signed underflow and overflow rejection without changing the process locale.
AI-assisted: yes (OpenAI Codex). Windows WinLibs GCC15.2 Release: original shared Json2 fails the final locale regression; fixed guest_json and guest_json_numeric_locale pass (2/2, no skips). Final conventions pass. Only relevant runtime/test targets built; full build/full suite and game/console/Linux/macOS behavior unverified. No performance or coverage increase claimed.
sceNpGetAccountCountry, sceNpGetAccountDateOfBirth, sceNpGetAccountLanguage
and sceNpGetParentalControlInfo take an online id that matches no user,
sceNpGetUserIdByOnlineId and sceNpCheckPlus report NP as signed out, and
sceNpNotifyPlusFeature is declared and throws.

Track the handles sceMoveOpen issues. A handle that was never opened,
is closed or was opened before sceMoveTerm now throws instead of
succeeding, since the console's INVALID_HANDLE result and its order
against INVALID_ARG are not known. List the no-controller path under
Silent stubs, as libSceHmd and libSceBluetoothHid do, and check the
handle values in the test.

The Linux entry stub now passes each traced import through libc.prx's
TraceImport_nid_no_patch before it calls the guest entry, and stores the
returned thunk in the import's slot. The same imports are traced as on
Windows: functions bound through a PLT slot or a GOT slot, without an
addend, and not weak. TraceImport_nid_no_patch is bound eagerly through
an added GLOB_DAT relocation, so a libc.prx without it fails at load.
Each slot's page is made writable with mprotect first, so slots inside a
PT_GNU_RELRO range can be replaced.
--trace-imports now requires libc.prx among the libraries on Linux too,
and is refused with --macos.
A thread that lost the race to write the report passed SIGABRT on straight away, and the default action ended the process while the first thread was still writing. It now waits for the report to finish, polling with nanosleep for at most 2 seconds, before it chains. guest_call_trace_abort_race aborts from two threads at once and checks the whole report; it failed 35 times in 50 without the wait. Reported by jotitadev.
The SIGABRT handler used stdio and dladdr, so an abort raised while another thread held the stderr lock or the loader lock hung instead of ending. The report is now formatted into a stack buffer and written with write(2). Callers are named from a module list taken with dl_iterate_phdr when imports are traced, and import counts are read without a lock from a fixed record array. The abort test now holds the stderr lock in another thread, which timed out before this change.
Build the call tracer for Linux as well as Windows. The thunk area is a
memfd mapped twice, writable and executable, and threads are named by
gettid. Linux has no crash report, so the first traced import installs a
SIGABRT handler that prints the last calls and the most called imports,
then passes the signal on to the previous handler.
guest_call_trace and guest_call_trace_abort now run on Linux too.
The 73 sceNpCppWebApiUnknown<nn> stubs carried an APS5_EXPORT alias because their
names were placeholders. aerolib names all of them, and each name recomputes to
the NID a title imports, so the alias is dropped and the loader derives the NID
from the real symbol name, as the rest of the library does. Behaviour is
unchanged: every one of them throws.
The stubs are ordered by demangled name instead of by NID, so the Common template
instantiations and the V1/V5 accessors sit together, as the rest of the file
does. No symbol changes: the built .prx exports the same 359 NIDs as main.
