The final piece of the lid-closed field report (fixes 1-3: 3d9b3290;
prerequisites: 85dd2bb0 pf-mouse, 845a9760 leaf primitives, 94ca4041
pf-capture hook): the IDD first-frame gate can only pass if DWM composes
at least one frame, and a lid-closed/locked/idle machine is exactly the
state Windows has decided not to compose in. The SendInput compose kick
is conditional on this process's context — wrong session → wrong input
queue; secure desktop → blocked; display powered off → no wake. A report
from the resident pf-mouse HID device is REAL input to win32k:
session-independent, secure-desktop-proof, wakes a powered-off display,
counts as user presence. Parsec-class mechanism, and semantically honest
— a remote user starting a stream IS a user arriving at this machine.
- hid_kick(rect, bounds): newest-wins kick slot + condvar, serviced by
the keeper thread that owns the ONE process-wide VirtualMouse (a
second open() would squat the bootstrap mailbox). Not-ready (opt-out,
driver missing, not yet attached) returns false → the capture crate
falls back to SendInput.
- perform_kick: park the pointer at the target display's center, dwell
35 ms (Stage-W3: DWM samples cursor position at the next vsync tick;
the gaps also keep reports from coalescing in the driver's 8 ms
timer), wiggle ~2 px, restore the saved position. Desktop→HID
coordinates normalize against pf_win_display::desktop_bounds() (CCD
union — correct from any session, unlike per-session GDI metrics).
- ensure_resident registers the hook (pf_capture::HID_COMPOSE_KICK) —
the one-way-edge inversion: pf-capture never reaches into inject.
- keeper loop: condvar wait (250 ms tick) so a kick executes
immediately, not at the next tick; publishes MOUSE_READY from
driver_proto.
Paired with pf-frame's DisplayWakeRequest (held by the capturer from
before the first-frame gate): the power request keeps the display from
going dark mid-session, the HID kick wakes it when it already is.
Verified on winbox: combined-tree cargo check + clippy for
punktfunk-host, pf-capture, pf-frame, pf-win-display all EXIT 0.
