Wait up to 2 s for the cancellation callback instead of one 50 ms run-loop
pass, count only callbacks without stored addresses so a completed lookup
cannot pass as a cancellation, print the failing stage, and have the runner
require the exact success line since Darling can exit zero after a trap.

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.
Drop the tooling that drives, automates, inspects, profiles, captures or
patches the Riot client and League game process, plus the historical
research/tools probes. These were never part of the supported workflow and
involve synthetic input, attaching to Riot's process, driving its local API,
or patching its binaries.
Removed from tools/: the baron-* and practice helpers, uinput_click.py,
lcu-practice-game.py, check-riot-vanguard.py, the riot-league-* / riot-open-url-*
inspector hooks and API/state helpers, the riot-*-watch.py observers,
riot-match-capture/ profilers, riot-cursor-watch/, the analyze-*/symbolize-*
profilers, capture-game-perf.py, the native VPX bridge and the client
log-dir/autofill shims. Removed all of research/tools/.
The supported launch/install pipeline is unchanged: scripts/, the launcher and
ensure-* helpers, fetch-installer.sh, stop-darling-runtime.py, the
build-*-runtime / build-m58f3* runtime builders, the install-* overlays and
offline installer checks, and the standalone operator/-check regression probes
are all retained. Docs that referenced the removed tools were updated.
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.

The counters (user space, counting only) show page walks cost the game's
main thread at most 3.5% of its cycles, so huge pages for its code are not
worth pursuing and for its heap are worth at most 1-3%.

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.
