Fix X11 presentation handoff after resizing, preserve NSView size callbacks, and correct content and backing-layer geometry. Add CoreText font enumeration for the language dropdown and rebuild/install the matching runtime overlays.
Correct CarbonCore Gestalt version queries and roll back proc_listpids for Vanguard testing. Document that VAN -101 can still recur. Include accumulated CoreAudio stream and AudioUnit corrections.
Add standalone font, version, resize and publisher-handoff regressions. Record manual confirmation of the language dropdown and window resizing; all 29 pinned patches and the source/script audit validate.
proc_info callnum 1 (proc_listpids) previously fell through to the unsupported-callnum path and returned ENOTSUP, so process enumeration (e.g. the Riot client's Vanguard kext probe) logged 'sys_proc_info(): Unsupported callnum: 1'.
Walk /proc like _sysctl_proc and _proc_pidinfo_listthreads already do and mirror XNU's filter semantics for PROC_ALL_PIDS, PROC_PGRP_ONLY, PROC_PPID_ONLY, PROC_TTY_ONLY, PROC_UID_ONLY and PROC_RUID_ONLY, with XNU's size-query, ENOMEM and truncation contracts.
setHiddenUntilMouseMoves: only hid or showed the cursor, so the flag set
by setHiddenUntilMouseMoves:YES was never cleared when the user moved the
pointer. Track and clear it in NSDisplay instead of NSCursor: add
setCursorHiddenUntilMouseMoves: and pointerMoved to the display, let the
X11 backend report genuine motion (after its synthetic warp filter), and
have NSCursor forward to the display. The idempotency guard keeps the
hide/show state balanced and preserves an explicit [NSCursor hide].
Electron 22.3.27's NativeWindowMac::IsVisible() compares the window's
occlusion state for exact equality with NSWindowOcclusionStateVisible:
bool occluded = [window occlusionState] == NSWindowOcclusionStateVisible;
Apple's contract is a bitmask: an on-screen window's state *includes* that bit
(tested with &). The exact == test is inverted, so an Apple-correct value made
every ordered-in window look occluded and the client's visible/not-minimized
checks failed. The previous workaround byte-patched Riot's shipped Electron
Framework to flip that comparison.
Fix it in Darling's AppKit instead: -[NSWindow occlusionState] now also reports
the reserved 1 << 2 bit for an on-screen window. &-based readers (Electron's own
windowDidChangeOcclusionState:, Chromium) still see NSWindowOcclusionStateVisible
set, while the exact == test is false, so unpatched Electron resolves
IsVisible() correctly. No Riot binary is modified.
Delete tools/patch-riot-electron-visibility.py and its call in
install-riot-gpu-runtime.sh; sync README and docs/STATUS, which already
described the binary patch as excluded.
iokitd passed an Xlib Display to eglGetDisplay(), so Mesa chose the
platform from EGL_PLATFORM. Wayland sessions often set it to "wayland",
and the first darling command passes its environment to every guest
service; Mesa then treated the Display as a wl_display, iokitd crashed
in pthread_mutex_lock and launchd restarted it every 10 seconds. Use
eglGetPlatformDisplay(EGL_PLATFORM_X11_KHR, ...) as OpenGL already does.

LaunchServices now hands http, https and mailto URLs to the host desktop
itself instead of NSWorkspace writing them to a spool that nothing in
the normal workflow drains. It loads the host libsystemd through the ELF
loader and calls xdg-desktop-portal OpenURI on the session bus, falling
back to xdg-open in a transient systemd user unit, so the browser starts
outside Darling's namespaces. LSGetApplicationForURL reports the host
opener for these schemes because Electron checks for a handler before
opening a link. NSWorkspace goes through LSOpenCFURLRef.
Tested with a host-side D-Bus regression (79 checks) and in a fresh
guest prefix through open(1) and NSWorkspace, both reaching the portal
with the exact URL.

Two matches with the Indium hand-off round (narrow present wait, deferred
blits, worker-side command-buffer lease, skipping CPU Vulkan devices) ran
slower than before, with more main-thread futex waiting. Each change is now
behind a guest flag file and off by default, so the default libindium matches
the round-3 build (vertex-descriptor dirty masks, cheaper resource setters).
The wait counters stay opt-in, write a "waits enabled" line when they are on
and keep their state per image. The docs explain that flag files created from
the host while Darling runs may stay invisible through the overlay mount.
Also adds a passive cursor watcher. The stuck in-game cursor is Hyprland's
direct scanout, not Darling. The first match with direct scanout off averaged
135 FPS. STATUS, TROUBLESHOOTING and README are updated with the new matches.

Game process (ARAM Hexgate: 84 -> 127 FPS average, slowest stretches ~110):
- Local pthread mutexes, condition variables and Mach semaphores are on by
default in the game process only, with /tmp/rclol-no-local-* opt-outs.
The main thread's darlingserver waits fell from 1.36 to 0.10 ms per frame.
- Local semaphores: the count and the slot generation change in one
compare-exchange, a destroy leaves a negative marker, the table is reset
after fork, and names the table did not create go to the server.
- Metal: drop identical re-binds (keyed on the Indium object, depth-stencil
retained), pass blit resources by reference, and stop resetting vertex
descriptors twice.
- Core isolation of the main thread is opt-in (/tmp/rclol-core-isolation);
it lowered FPS in its only match.
- Optimized libc/libc++/Foundation overlays, AVX2 string primitives, real CPU
topology and their installers and offline checks.
Tools and docs:
- tools/riot-match-capture: passive /proc sampler, user-space IP profiler and
reports, plus a comparison against the game's netstats.
- tools/riot-lsem-model and tools/riot-metal-bind-model: host models that
extract the shipped code and check it.
- tools/install-riot-metal-pair.sh installs Metal and Indium together.
- Status, setup, testing and troubleshooting docs updated with the measured
matches and the switch table; manifest file counts match the patches.

Preserve floating-point arguments in GL resolvers, retain presentation across differently sized windows, export AppKit click and URL fixes, and guard nullable LaunchServices errors. Include compiler/build and installer corrections for the new PC.
Reuse server receive buffers with descriptor-safe exception cleanup and avoid disabled debug-string allocation. Translate Darwin free/reuse memory hints, add atomic server/library installers with separate user-owned memory backups, and preserve active processes until a manual namespace restart.
Remove automatic inspectors, client helpers and forced unlimited UI frames from normal launches. Retain historical hooks with offline mocks and document their exclusion, unresolved installer handoff, activation requirements and unmeasured FPS/RAM benefits.
Validation: all 29 pinned patches apply; all 461 exported source files match; host receive and memory checks, launcher and JavaScript mocks, syntax and documentation-link checks pass. No live client/game was controlled or restarted.
