Open with no row selected passed nil to -_setFilename:, and NSOpenPanel boxed it in an
array literal, so the action threw before the modal session was stopped and the panel
stayed up. Both buttons now go through one helper that stops the session only when
this panel is the modal window and always orders the panel out; Open accepts the
selection (filtered by canChooseFiles/canChooseDirectories and multiple-selection),
or the shown directory for directory choosers. Escape cancels.

Restack and makeKey no longer map a window AppKit considers hidden, and
setIsVisible: NO always unmaps, so the client's splash stays hidden.

Synchronize Motif decoration hints on style and titlebar-property changes, including native-window recreation and restoring ordinary WM decorations. Add a ten-case standalone Cocoa/X11 regression probe and document validation on KWin/Xwayland.
#79 made update.sh stop Darling again after the overlays and run
configure-darling-platform.py --replace-known-defaults --write. The
rootless update test still expected the old call list and failed. Stub the
identity tool, expect the stop + identity calls last, and check a failed
install never reaches them.

The issue #75 trace shows recording now runs, but Vivox's playback unit
(mic test loopback, other players' voices) sets interleaved Float32 stereo
at 32 kHz on input scope element 0 and got -10868. Apply the relaxed rule
to both client sides (input scope element 0, output scope element 1); the
playback path already interleaves for the device and PulseAudio resamples.
AudioUnitRender(bus 1) now traces frames and peak level (no samples) so a
log shows whether the client pulls sound or silence. The input check also
sets Vivox's playback format and expects unsigned 16-bit to be refused.

RenderBus pads missing frames with zeros, which is loud for unsigned PCM
(silence is 0x80 for 8-bit, 0x8000 for 16-bit). Reject unsigned and 8-bit
formats on element 1; voice engines use float or signed 16-bit.

When install-runtime.sh creates the prefix (first-time setup, regular or
Nix), it now runs configure-darling-platform.py --provision --write once
the runtime is stopped, so each new install gets its own synthetic serial,
MLB, UUID and ROM. A prefix counts as new the same way Darling decides it:
the directory did not exist before the first `darling shell`. Existing
prefixes keep their identity on reinstall and update.

Older setups shipped serial C02ZL0GVMD6N and UUID
6F3B2A1E-8C4D-4E5F-9A7B-1D2C3E4F5A6B to every install. After installing,
update.sh now runs configure-darling-platform.py --replace-known-defaults,
which provisions the prefix only when its saved identity still has one of
those values. Other custom values (imported serials/UUIDs, model, board,
manufacturer, ROM, MLB) are kept; prefixes with no saved identity or only
custom values are not touched.
provision() also drops a standalone system-id or provisioning_UDID derived
from the shared UUID instead of keeping it.

Vivox sets interleaved Float32 stereo on output scope element 1 and
AUBase's canonical-only rule rejected it with -10868, so voice chat never
started recording (issue #75 trace: 20 attempts, all failing there).
A real AUHAL converts any linear PCM; element 1 now accepts native-endian
float32 or 8/16/32-bit integers in either layout, which PulseAudio records
and RenderBus copies. Playback (element 0) keeps the canonical rule.
The input check gains a Vivox-style run: interleaved stereo 44.1 kHz with
the device set on element 1.

last_close started at 0.0 and the cooldown compares it with
time.monotonic(), which counts from boot. For the first 30 s of uptime
every close was refused as "in cooldown". That made the tests flaky on
freshly booted CI runners (seen on PR #76). Use None for "never closed".

Right Alt (keycode 108) was hard-coded as Mod5/AltGr. On layouts where it
is Mod1, the swallowed-release reconcile accepted Mod1 as held but rebuilt
the state with Mod5, so the guest could see Option and Function together.
Read the per-key masks from XGetModifierMapping (refreshed on
MappingNotify) and use them everywhere; the old table is the fallback for
unmapped keys. The probe now checks Right Alt against whichever mask the
backend reports.

The handler read a flag the caller wrote without synchronization, and
inferred "called inside the request" from whether the call had returned,
which misfires when the handler runs on another thread first. Compare the
handler's thread with the caller's instead and keep the shared results
atomic.

GNOME's overview delivers the Super press to the game window, eats the
release and hands the keyboard back without a FocusOut. The backend kept
Command held, so every later key and click reached the game as a Command
shortcut until a real focus change reconciled it (issue #74).
Each key, button, motion and crossing event carries the server's modifier
state; release any modifier key we track as down whose modifier is missing
from it. Synthetic events from other clients are ignored.

Voice chat (Vivox) saw no capture device and Chromium was told mic
access was denied. Fixes for issue #75:
- AVCaptureDevice: audio is Authorized when CoreAudio has a default
input device; requestAccess answers asynchronously. Video stays Denied.
- PulseAudio input device reports 2 channels on input scope, 0 on output
(was copied from the output device).
- PulseAudio input stream: real sample/host timestamps, one device
buffer per IOProc call, holes as silence, IOProc errors no longer cork
the stream, record buffer attrs sized to the device buffer.
- AUHAL: two elements per scope like macOS, non-blocking
AudioUnitRender on bus 1 with planar support, device records in the
bus 1 format, input-only units route CurrentDevice/BufferFrameSize to
the input device, input start errors handled.
- New offline check tools/riot-audio-input-check.cpp.

A long patch or login can keep the League client closed for more than ten
minutes after launch; the helper then left before the first match.

Mesa derives its shader disk cache from $HOME. Inside the guest that is
/Users/<user>, which does not exist on the host filesystem, so Mesa could not
create the cache and disabled it, once per process:
Failed to create /Users/<user> for shader cache (Permission denied)---disabling
One launcher log contained 212 of those lines, and no shader compiled by one
process was reused by another process or by the next start: the client and the
game recompiled every shader on every launch, spending CPU at startup for no
gain.
Mesa is host code loaded into the guest and reads MESA_SHADER_CACHE_DIR verbatim,
so point it at a host directory; Mesa creates mesa_shader_cache/ (client and game
shaders) and radv_builtin_shaders/ below it. A non-empty value from the caller is
preserved, and a directory that cannot be created leaves the previous behaviour
instead of ending the launch.
Observed on a Radeon RX 550 with radv: no shader-cache failure after the change,
and 434 files / 5.6 MB written during one client start, still growing while the
client ran. The cache is reused from the second start on, which lowers the
client's CPU use while it starts; the startup-time gain itself has not been
measured separately.
The client does not come back properly after a match when its own "Close client
during game" option is enabled. The UI (LeagueClientUx and its helpers) is a
Chromium/CEF instance and, under Darling, the pre-match instance keeps running:
the client the backend starts when the match ends is a second CEF instance on the
same --user-data-dir, and its window never paints. Its DOM and audio work and the
window stays black; closing the client by hand during a match leaves the same
state for the same reason.
RCLOL_CLOSE_CLIENT_IN_GAME=1 opts in to closing that UI from the host, and only
while a match runs, so the client that appears afterwards is the only instance.
The UI also competes with the game for CPU: on a four-core host with a Radeon
RX 550 a practice match reported roughly 120 FPS with the UI running and roughly
180 FPS with it closed. This is not the helper-killing memory optimization the
RAM section warns against, and the Riot client, the League backend and the game
are never touched.
The helper fails closed. It attributes the game and the client to the launcher's
prefix through the loader's __mldr_sockpath, since guest processes do not carry
DPREFIX (checked on a live session). It never closes a client younger than 60
seconds (the one the backend starts after a match), preserves a process of
another installation or owner, acts only when the environment and the stat fields
can be read, gives up after three closes in one match, and leaves after ten
minutes without a client or a match. It is off by default.
Tests use fake /proc entries and mock every signal.
Riot's splash screens draw on a black rectangle: LeagueClient's is a
borderless NSWindow with setOpaque:NO and a pattern-image background, the
Riot Client's an Electron BrowserWindow with transparent: true. X11Window
created every window with a 24-bit visual and -setOpaque: only stored the
flag, so there was no alpha channel.
A non-opaque window whose background can show through (alpha below 1, or a
pattern image) now gets the 32-bit ARGB visual. League's game window is
non-opaque on an opaque background and stays on the opaque visual, which
X11IsLeagueGameWindow also enforces. The X window exists before apps set
opacity and background, so the choice is checked again when the first
subwindow is created (layer subwindows inherit the visual) and before the
first map, and the window recreated while unmapped if it changed. Its
background is transparent instead of None, so no black frame shows before
the first draw. Its surface comes from an alpha EGL config for that visual
(CGLGetWindowWithAlpha) and its compositing context from the surface's
config (CGLCreateContextForWindow): NVIDIA refuses the default config on a
32-bit window, and no driver makes a context from it current on the alpha
surface. Without an alpha config the window falls back to the opaque
visual.
A translucent window above the normal level (Electron's alwaysOnTop
splash) is typed _NET_WM_WINDOW_TYPE_SPLASH with _NET_WM_STATE_ABOVE before
it is mapped: window managers float it and draw no frame around it.
Electron's level never arrived, though: CGWindowLevelForKey returned the
normal level for every key, and the SDK turns NSFloatingWindowLevel into a
call to it. It now returns the levels macOS does; Cocotron only stores
levels, so nothing else changes.
