SignalAndModifyByWaitingCountIfEqual with count <= 0 and at least one waiter stored value - 1; Horizon stores
value - 2 (mesosphere KAddressArbiter::SignalAndModifyByWaitingCountIfEqual; yuzu, LAS Recomp and nxnative agree).
The word was already updated with compare-and-swap, as LAS Recomp 1144aea made theirs; the count > 0 values were
right.
--probe-kernel arbiter part expected the old value: it now wants 4 for value 6 with one waiter and count -1, and
4 for two waiters and count 0. Before: 5 for both. After: ok.

Ours took a pending CancelSynchronization first, before the signalled objects and before the timeout-0 return, so a
poll or a wait on a signalled object used it up and the blocking wait it was meant for ran on. Horizon checks a
signalled object, then timeout 0, then the cancel (mesosphere KSynchronizationObject::Wait; LAS Recomp 1144aea moved
the poll the same way): both keep it pending. A cancel that wakes a blocked wait still ends it cancelled:
CancelSynchronization now wakes it with R_CANCELLED, which the loop tells apart from a signal's -1.
--probe-kernel events part: a cancel sent before a poll and before a wait on a signalled event; each is followed by a
blocking wait with a 500 ms timeout. Before: the poll and the signalled wait returned 0xec01 (cancelled) and the
blocking waits timed out (0xea01). After: timeout, success, then cancelled both times.

Reverts dafc35f: free_cores = 1 in totk.ini lifts the virtual core gate again, as in 0.2.8. The mode stays as an
experiment, and every place a player meets it says the game crashes: totk.ini.example, a WARNING line in the start log,
and a line under every crash report and FATAL while the gate is off (kern_free_cores_note), so a log from #212 names
the cause at once.

Earlier settings menus wrote free_cores = 1 under the label "Virtual core gate", which promised the gate. Without it a
thread that holds no virtual core reports its ideal core to GetCurrentProcessorNumber, so the game's job workers all
report core 0 and run its per-core code at once. On 1.2.1 two of them add the same per-core NVN control memory, which
retires the command handle the other just recorded, and its CallCommands fails at start (#212); on 1.4.3 the game
corrupts a heap in main+0x82e00 or hangs at the title menu. A player with such a totk.ini crashed at every start and
the menu no longer shows the row.
free_cores is no longer a setting: only TOTK_FREE_CORES in the environment lifts the gate, and a free_cores value in
totk.ini is logged as ignored. The kernel probe asks the kernel whether the gate is on.

The branch forked 79 commits before main and 98 before dev. Resolutions:
1. Aspect ratio: dev's implementation stays (camera patch at page +56 on 1.4.3, tools/ultrawide_layout.py layouts per
size in romfs-patches-<w>x<h>, the aspect = fit|stretch setting). The PR's second implementation is dropped: the
aspect sets of patches-v121.txt and patches-v143.txt (the 1.4.3 one patched the same viewport sites as dev's),
tools/aspect_layouts.py, the resolution.c shapes that limited game resolutions to 16:9, 16:10 and 21:9, and the
picture_fit setting. Its letterbox code (gfx_fit_rect) is kept and reads TOTK_ASPECT.
2. Code dev changed where the PR moved it: the stick dead zone, the test gamepad and the paddles go to input.c; the
DPI awareness, keep-awake and IME detach of gfx_window.c go to gfx_window_win.c; device fault reports and GPU
breadcrumbs to gfx_present.c. gfx_window_dpi gets an SDL version.
3. dev's Win32 calls in shared code go through platform.h: the shader cache pack reader (PlatFile), the romfs
overlay checks, the audio pacing waits, the motion, ASTC and device fault locks. plat_cpu_usable and
plat_commit_info get Linux versions; plat_cpu_count counts the machine's processors on both. dpi_probe.c becomes
dpi_probe_win.c.
4. assume_focus defaults to 1 as the PR has it (a load interrupted by a focus loss can stop for good) and stays live,
with dev's Game tab row.
5. The frame limits 40 and 45 join dev's list. The BC 3D storage fallback for Vega only runs with
TOTK_BLOCK_VIEWS_3D=1, since dev makes 3D BC images without block views by default.

Eight places sized a pool (pipeline workers, library prebuild, translator prewarm and seeding, the multithreaded ASTC decoder) by GetActiveProcessorCount, every logical processor of the machine. A process limited with start /affinity, Task Manager or a launcher then started a pool for 16 CPUs on 4. plat_cpu_usable counts the affinity mask (all active processors for a process that spans processor groups); plat_cpu_count, the machine's count, stays for the system info. Idea from MMadmer's UsableCpuCount in a fork of the Shadow of the Colossus PC port.
Shared runtime code now goes through runtime/platform/platform.h, implemented by platform/win32.c and a new
platform/linux.c: futex locks, a userfaultfd and PAGEMAP_SCAN write watch, signal-based async preemption, our own
fiber switch, and a SIGSEGV handler for the thaw and crash hooks. The window, input, menu and software keyboard get
SDL3 back ends beside the Win32 ones, with the swapchain (gfx_present.c) and input merging (input.c) shared. SHA-256
replaces BCrypt, ELF builds get their own override sections, and the build tools gain Linux branches.
On Linux the selftest and the gfx-abi, astc, nvn and window probes pass. probe-vkmem still fails: imported guest
memory cannot be write-watched on Linux, which the shadow buffers in vk_memory.c will address.
