With LTO, GCC inlines the IME handlers into the test that passes a
32-byte buffer and warns that strndup's 256 KiB bound exceeds it
(-Wstringop-overread). The read never passed the NUL, since libwayland
always terminates protocol strings, but the warning reached consumers
such as wsap_term.
The text is now measured with strlen, capped at IME_TEXT_MAX, and copied,
which keeps the same truncation. An LTO release build is warning-free.

wsap_term writes PNG screenshots for its debug server and keeps its own
copy of the frame because YASL had no readback.
yasl_surface_read_pixels() copies the frame from the last successful
present, or reports its extent when the buffer is too small. X11 and
Cocoa keep it in their single CPU target until the next draw starts;
X11 now also forgets it when a resize replaces the target, and Cocoa
records the presented extent because a resize can change the size before
the next draw. Wayland remembers which buffer it committed and forgets it
when a draw reuses that buffer.
The backend test checks the copy on Wayland and X11, and that draws that
never present do not show through. The Cocoa path is not built or run
here.

wsap_term hardcodes 400 ms in three places to count clicks.
yasl_display_double_click_ms() reads the interval from the system. X11
parses Net/DoubleClickTime from the XSETTINGS owner's property. Wayland
has no protocol for it, so it asks the Settings portal for KDE's
DoubleClickInterval, which KDE sends as a string and which exists only
when the user set it, then GNOME's double-click. X11 without XSETTINGS
asks the portal too. Cocoa reads NSEvent.doubleClickInterval. Missing or
implausible values give YASL_DOUBLE_CLICK_MS_DEFAULT, 400 ms.
The X11 state test covers the XSETTINGS parser in both byte orders and
with truncation. The Xwayland test owns the settings selection. The
desktop test serves both portal keys. The Cocoa path is not built or run
here.

wsap_term keeps per-platform code for opening links, notifications, the
bell, high-contrast detection, the executable and bundle paths, and the
default locale. These now live behind <yasl/desktop.h>.
On Linux, src/platform/freedesktop serves both backends. Opening a URI
runs xdg-open from PATH through a double fork, so the opener gets default
signal dispositions, an empty mask, a new session, and none of the
application's descriptors. Notifications and the Settings portal use the
session bus through libdbus-1, an optional dependency behind -Ddbus.
Appearance falls back to GTK_THEME without a portal. The bell uses
xdg-system-bell on Wayland and the XKB bell on X11.
Cocoa implements the same calls with NSWorkspace, UserNotifications, the
effective appearance, NSBeep, the bundle, and CFLocale. That code is not
built or run here; it needs a macOS check.
The desktop test runs under dbus-run-session against a fake notification
server and portal, and uses a fake xdg-open to check argument passing,
signal state, and descriptor inheritance.

Pointer events set button only on press and release, so wsap_term tracked
held buttons itself to tell a drag from a hover.
yasl_pointer_event.buttons now holds a YASL_BUTTON_BIT() mask of the buttons
held after each event. The common input queue tracks it from the DOWN and
UP events it queues, and clears it on INPUT_RESET and on allocation
failure. Wayland also clears it on leave, since the compositor sends leave
during a press only when it takes the pointer and no release follows. X11
and Cocoa keep it, because they deliver motion and the release to the
pressed window after leave.

wsap_term runs its own eventfds to wake the loop from its pty worker and
accessibility threads, and its own signalfd or self-pipe per platform.
yasl_loop_kick() is now documented as safe from any thread and from a
signal handler. yasl_loop_post() queues a function to run on the owning
thread during a later step. yasl_loop_watch_signals() installs a
process-wide SA_RESTART handler per signal that records the signal and
kicks the loop, so callbacks run on the loop thread on every platform
without touching thread masks.
Cocoa dispatch waited only for AppKit events, so kicks, posts, and fd
watches could not end an indefinite wait, and yasl_post_event() did not
wake yasl_run(). While waiting, Cocoa now mirrors the loop's descriptors
in a kqueue whose run loop source posts a wake event. If kqueue rejects a
descriptor, the wait is bounded to 10 ms.
The Cocoa change is not built or run here; it needs a macOS check.

yasl_surface_set_pointer_mode(YASL_POINTER_RELATIVE) now takes a
persistent zwp_locked_pointer_v1 on the surface and hides its cursor.
While the compositor keeps the lock engaged, zwp_relative_pointer_v1
motion is pushed as POINTER_MOTION with pos frozen and delta in device
pixels. When the lock disengages, as on focus loss, motion is absolute
again with a delta derived by the input queue.
The lock follows the pointer's seat: it moves to another seat when its
seat loses the pointer, and is released on NORMAL and on surface
destruction. Compositors without both protocols return false.

The core input queue and the yasl_run() runner each had their own event
type, and the runner translated one into the other. Both now share
struct yasl_event in <yasl/yasl.h>: yasl_surface_poll_event() returns the
same events the app event callback receives, so the runner forwards them
unchanged.
Pointer input becomes POINTER_DOWN/UP/MOTION/SCROLL/LEAVE with a named
yasl_pointer_button and a motion delta computed in the input queue. TEXT,
PASTE and DROP share one text payload, scale changes fold into
WINDOW_RESIZE, and every event carries a monotonic time_ns.
yasl_surface_set_mouse_mode() is replaced by
yasl_surface_set_pointer_mode(); no backend implements relative mode yet.
The export check now only counts YASL_API declarations, so function
pointer fields returning enum yasl_app_result are not mistaken for
exports.
