Create and advertise one reliable input stream for each possible LGMP
client, then bind endpoints to active input subscribers.
Drain endpoints fairly while prioritizing the current owner's lane so
its RELEASE remains the ordering barrier. Reject transport changes
within an activation generation.
Gracefully retire missing or stalled subscribers without reusing an
active reservation. Keep excess clients on the queue and release HID
ownership from the input worker when its stream retires.
Make CSRWLock own the native lock and provide scoped guards for shared,
exclusive, early-unlock, and non-blocking use.
Replace direct SRW lock management throughout the IDD, input driver,
and helper while preserving the existing lock scopes.
Move named pipe writes off the LGMP input worker so a stalled LGInput
endpoint cannot block queue draining or lease maintenance.
Coalesce motion only under queue pressure while preserving mode, button,
wheel, and keyboard transitions. Reset HID state after discontinuities
and carry all 32 mouse button bits through the pipe and HID reports.
Add an optional input transport and a dedicated LGMP receiver that
validates source ownership, generations, ordered sequences, and leases.
Poll input outside the 10 ms control timer. Forward mouse and keyboard
state through the LGInput pipe, and neutralize the endpoint before
ownership changes or transport failures can leave input held.
